Patent Number Date Title Name City Description
14,863 May. 13, 1856 Handsaw Jackson Gorham Bairdstown, GA Combination square and saw and the first in the 7/150 catagory. This patent was utilized by Henry Disston in the No. 42 and 43 series of saws and early examples will bear the incorrect patent mark of MAY 12,1856 instead of MAY 13,1856. Hiram Smith specifically mentions this patent as a basis for his patent, 20313, which was assigned to Henry Disston.
Disston catalog pictures as well as know examples are marked with the incorrect patent date of MAY 12,1856 as well as JACKSON GORMAN in an arch above the date.

A featured article in Scientific American, 15 AUG 1857, describes the saw as well as indicates to contact H. Williams, assignee, in Atlanta GA for more information.
20,313 May. 18, 1858 Device Attached to Handsaws for Squaring and Marking Hiram Smith Camden, NJ References improvements on the Jackson Gorham patent, 14863, of 12 MAY 1856. Shoulder strips are riveted directly to the blade instead of the handle to ensure squareness is maintained. A sharp projection occurs at the beginning of the rule for reference and an awl is provided in the handle for marking.
20,337 May. 25, 1858 Leveling Device Attached to Handsaws Henry Disston Philadelphia, PA One of the patents that is the basis of Disston's No 43, No 42, and No 39 combination saws. Text specifically mentions that it may be combined with the Jackson Gorham's patent 14863 (also noted on the 43 series saws). Patent is for the levels in the handle positioned for plumb and level with respect to the back edge of the saw.

Note the spelling of Morse verus Morss. Strangely, the original patent page is missing the signatures to help asertain if this spelling is correct or an error in typesetting. Thomas L. is reported to be the father of Joab Morss of the venture of Disston and Morss.
    Leveling Device Attached to Handsaws Thomas L. Morse (Morss) Philadelphia, PA

67,734 Aug. 13, 1867 Improvement in Hardening and Straightening Steel Blades Henry Disston Philadelphia, PA Simulataneous hardening and straightening blades of steel using gradual pressure between plates and dipping the blades into the hardening composition while the blades are in a heated state. Disston subsequently applied for a different patent, 86286, since while this method worked well for handsaw blades and thin strips of metal, it did not allow larger circular saw blades to be adequately coated with the hardening composition.
70,423 Nov. 05, 1867 Improved Device for Setting Saw Teeth Henry Disston Philadelphia, PA Notched swage hinged to rods that enable the cutting edges when set by the swage to be the same distance from the center of the saw.

72,766 Dec. 31, 1867 Improvement in Bolts for Saw Frames, &c F. Washbourne New York, NY Head and shank made separately and then brazed together as an improvement over a cast saw bolt. Frequently found on American, and some Canadian, split nut saws and also sometimes observed with the patent stamped on the bolt.

WRT Canadian use, Rob Paul reports "Flint of Rochester opened his saw works in St Catharines Ontario in 1856 (the first saw works in Upper Canada), and sold to R H Smith in 1870. From my collection, R H Smith initially used a J Flint medallion and his own blade etch which included "R H Smith, Successor to J Flint", then an early "R H Smith" flush mounted split-screw medallion has no patent date, and later surface mounted R H Smith medallions have the 1887 Glover Pat date"
73,238 Jan. 14, 1868 Improvement in circular saws Henry Disston Philadelphia, PA Circular saw patented gullet tooth. Each tooth has the back edge formed as an arc of a circle with the center eccentric with the center of rotation (image 2). Sharpening lines of teeth continue to ensure that same number of teeth remain as the saw diameter is reduced thru sharpening. Use of one of Disston's patented gummer is referenced.

Prominently displayed in the 1876 Price List
79,184 Jun. 23, 1868 Improvement in Swage for Circular Saws John Gulick Baker Philadelphia, PA An improvement over Henry Disston's patent, 70423, which was apparently put into use at the Disston works and this patent reflect the experience with the earlier patent in use.

The swage is hung loosely to the bar and its movement is independent but limited by a pin in the bar. Disston's patent had the swage secured to the bar when used.
80,242 Jul. 21, 1868 Mincing Cleaver Samuel J. Tongue Philadelphia, PA Munn & Co.- patent attorneys
This invention consists in combining a mincing knife or cutter, and a cleaver, in such a manner that one and the same implement may be used either in the capacity of a cleaver or a mincing knife, as desired. In using the implement as a cleaver, the handle is grasped horizontally, in the usual way, the cutting edge rising and falling in the vertical plane; but in using the device as a mincing-knife or chopper, the handle is grasped vertically, and worked up and down in that position.
Blade is stamped "Disston, Philada, Warranted, Patent July 21st, 1868."
86,724 Feb. 09, 1869 Improvement in Screw Driver Handles Eli S. Bitner Lock Haven, PA A smooth metal cap fits loosely in a socket in the top of the screwdriver to eliminate friction to the palm when driving screws.

152,347 Jun. 23, 1874 Improvement in Handsaws Henry Disston Philadelphia, PA Skew back handsaw. Changing the back from straight to skew reduces vibration of the saw and it makes the saw less likely to jar the operator causing kinks.
157,634 Dec. 08, 1874 Improvement in handles for saws William J. Reagan Royersford, PA Recess for thumb - right hand only. Primarily used on the Disston No 9 improved backsaw and also occasionally found on Disston's No 4 backsaw models. Unknown if the the use on No 4s was a catalog item or a special order. Early handles have the patent number stamped near the recess.

Reagan also held a patent 154,904 an improved casting for school desk arms.

The patent specification gives the patentee's location as "Royer's Ford" rather than the usual spelling of Royersford.
163,162 May. 11, 1875 Improvement in Saw Sets Henry Disston Philadelphia, PA Handled saw set/saw wrest designed to accomodate teeth of different thickness by utilizing a revolving disk with openings corresponding to the blade thickness along with set screws to secure the disk as well as limit the set.

181,422 Aug. 22, 1876 Improvement in Handsaws Henry Disston Philadelphia, PA A hole thru the blade facilitates a screw/bolt to secure the blade to the back of a backsaw as either a "U" shaped clamp or as part of the frame. Would prevent the blade from working its way out of the metal back as is sometimes encountered with backsaws.

Known example with closed handle but apparently a short lived design.
    Improvement in Handsaws Charles T. Shoemaker Philadelphia, PA  
181,421 Aug. 22, 1876 Improvement in tabs for gang-saws Henry Disston Philadelphia, PA
181,650 Aug. 29, 1876 Improvement in Saw Blades Henry Disston Philadelphia, PA Handsaw blade's double taper is accomplished by rolling rather than previous method of grinding which wasted metal and reduced toughness of the blade.
181,648 Aug. 29, 1876 Improvement in Securing Saw-Handles to Blades Henry Disston Philadelphia, PA The heads of the saw screw and nut are slightly domed, and their outer edges beveled so that they flare outward toward the face. Additionally, the screw is received by a blind threaded socket in the tubular projection of the nut. The tubular projection may, or may not, be long enough to engage the saw blade. Disston expresses a preference for those which are long enough to engage the blade. The overall purpose of this patent is to allow the handle and the saw nuts and screws to be finished and polished prior to assembly, with the beveled edges of the bolts/screws forming their own seats in slightly undersized shallow holes bored into the handle. This also allows for the saw nut to be subsequently tightened without altering appearances.

Saw nuts based on this patent were cast, making them relatively expensive to produce. Additionally, the shafts were relatively thin, so were prone to twisting off. In time, they appear to have been superceded by Glover's patent (375350).

Figures 4 & 5 of the patent drawing were added to illustrate the common "split nut" arrangement which Disston intended to replace.
183,805 Oct. 31, 1876 Improvement in Methods of Attaching Saws to Handles Joseph Holden Middletown, NY Handle with thumbscrew to allow a slotted blade blade to be inserted/removed. Slot in handle allows the blade to be placed in four different positions.

Initially produced by WM&C and later offered by Henry Disston & Sons as the No. 70 Holden Pattern Compass Saw.
188,243 Mar. 13, 1877 Improvement in Wrenches Willis D. Gold Philadelphia, PA The tool is a steel bitted screwdriver, with the malleable iron handle containing several wrench openings on the sides and end. It is called an improvement on Gold's May 14, 1867 patent (no. 64,662). One version of the tool may have been a tool kit screwdriver for Domestic sewing machines.
According to Ken Cope's "American Wrench Makers 1830-1930" H. Disston & Sons of Philadelphia produced this as the Excelsior Wrench and Screwdriver.
188,604 Mar. 20, 1877 Improvement in Combined Pruning Shears and Saw Thomas S. Disston Philadelphia, PA
189,199 Apr. 03, 1877 Improvement in insertible saw-teeth Thomas S. Disston Philadelphia, PA

194,659 Aug. 28, 1877 Improvements in Saw Handles Henry Disston Philadelphia, PA Keyhole style metal saw handle. Known examples have the patent date cast into the handle.

Interesting to note that this appears to be one of the few patents that Henry Disston assigned to his brothers but perhaps only as a result of the dual inventor status.
    Improvements in Saw Handles John Vandegrift Philadelphia, PA  
201,276 Mar. 12, 1878 Improvement in Spirit Level and Plumb Joab Morss Philadelphia, PA Adjustable level and plumb. Bearing point is rigid while the adjusting screws act directly on the vial casing which is claimed to provide a more certain and delicate adjustment than adjustments provided by springs or spring arms.

298,709 May. 13, 1884 Saw John Smith Philadelphia, PA
310,420 Jan. 06, 1885 Combination Gage Andrew J. Hellings Philadelphia, PA Robert C. Barrie - patent attorney

From about 1885 to 1910, Disston made a variety of Machinist's tools.

This invention relates to that class of devices, which are used by mechanics in truing up work of different forms, and it has for its object to furnish a gage for square corners, hexagonal corners, and equilateral triangles, for finding the center of a square, for measuring the angle of a center hole, and for measuring the depth of apertures. I am aware that gages for trying squares and angles of sixty degrees, also narrow rules for measuring, are common.
311,435 Jan. 27, 1885 Saw Almon Lord Brooklyn, NY Metal strap is riveted to the blade and attached to the handle by screws. Very similar to, and references Hankin's patent 295,385, with the exception that the metal "clamps" the handle by extending past the top surface to embrace a portion of the handle side. Originally produced by Harvey W. Peace Co. and marketed as the "Vulcan" and later produced by Henry Disston and Sons as the D-24 Pruning Saw.
326,798 Sep. 22, 1885 Saw with insertible teeth John Smith Philadelphia, PA
367,605 Aug. 02, 1887 Saw Thomas S. Disston Philadelphia, PA
375,350 Dec. 27, 1887 Saw Screw Charles Glover Hartford, CT The primary focus of this patent is on the two-part construction of the saw medallion ("label screw"). In a sense, it can be seen as an improvement on Munger's patent (U.S.P.N 98180), which had no provision for preventing the shaft from twisting independent of the head if the swaged fit failed. The large show surface of Glover's medallion, in conjunction with the shoulder beneath it, allowed for the addition of longitudinal ribs on the shaft of the screw to resist turning.

The medallion (figures 2, 3 & 4) and the saw screw (figure 5) shown in Glover's patent drawings both feature the internally threaded construction patented by Henry Disston in 1876 (U.S.P.N. 181648). This form displaces the through screw and "split nut" arrangement which had been the norm. Glover's saw screw differs from Disston's by being formed in a die rather than being cast and having longitudinal ribs on the shaft rather than a square section to resist turning. Also, though not specified in the patent, the shafts of Glover's saw nuts were of stouter construction. Glover's form eventually superseded Disston's.

Saw medallions with this patent date have been found on saws from a wide variety of saw manufacturers.
395,218 Dec. 25, 1888 Handle for Crosscut-Saws Christopher Eisenhardt Philadelphia, PA
412,024 Oct. 01, 1889 Device For Inserting Saw Teeth Thomas S. Disston Philadelphia, PA The wrench has a pin that fits in a hole in the tooth, and lugs that bear on either side of the cutting tip of the tooth. It conforms to the form of insertable teeth used in Disston circular saws of the period.
429,019 May. 27, 1890 Saw-gumming machine Thomas S. Disston Philadelphia, PA This patent gummer was featured in the 1895 catalog from Montgomery Ward as "Disston's Patent Self Feeding Saw Gummer. Showing the Victor in position for work on a 60-inch circular saw..."

628,775 Jul. 11, 1899 Cane Knife Henry Disston Philadelphia, PA Corrugations are used on the portion of the blade that is close to and secured by the handle. Claims to overcome the problem of light cane knifes of breaking at the handle and with the corrugations the additional strength afforded, allows the design to remain light (and be able to be used by women and children).
636,168 Oct. 31, 1899 Saw Set Matthew Odgers Philadelphia, PA Sold as Disston's Triumph Saw Set and kept in production until the 1940s.

687,583 Nov. 26, 1901 Saw Handle Edwin F. Shaw Philadelphia, PA Improvement over Shaw's 684729 patent for a metal handle saw. It appears that the improvement is the inclusion of internal flanges at the upper and lower edges, the handhold, and depressed flanges forming the recess for the back of the saw.
687,584 Nov. 26, 1901 Saw Handle Edwin F. Shaw Philadelphia, PA Complementary patent to his patent 687584 for a butcher saw handle. Continuation from his earlier metal handle patent, 684729. In this patent instead of two mirror image pieces, the two pieces consist of a body section and a handle section that are joined together.

919,883 Apr. 27, 1909 Square Ernest A. King Philadelphia, PA Traditional cabinetmakers square where the blade and stock is made of one piece in order to keep it square in spite of rough handling. The brass face of the square is attached to the wooden scales without weaking the scales as the pins are wedged into the slot between the scales.
938,680 Nov. 02, 1909 Adjustable and Detachable Handle for Saws Robert E. Martin Newark, NJ Nine claims for this patent although essentially means to easily attach/detach saw blades and adjust the angle of the handle. Serations on the blade and handle to assist in positioning. Applicable to both traditional handsaws and compass saws. Similar to the patent, 885521, used by Bishop and Simonds with the main visual difference the use of single blade tightening nut on the former and a more conventional two bladed (wing) tightening nut on the latter. Manufactured by Henry Disston & Sons, Richardson Bros, and Atkins.
