252,177 Jan. 10, 1882 Gong Bell Frederick W. Brocksieper New Haven, CT John E. Earle - patent attorney
This invention relates to an improvement in that class-of gong-bells which are placed directly upon the inside of a door to be operated by a lever upon the outside, or, placed at a distance, may be operated by a connected wire-pull, the object of the invention being a simple construction to avoid the hinged latch necessary in the usual construction.

303,478 Aug. 12, 1884 Tool Handle Granville W. Wright New Haven, CT Claim is for the tubular socket and a pin that goes through both the socket and jaws to prevent longitudinal movement.
303,887 Aug. 19, 1884 Tool-handle Joseph B. Sargent New Haven, CT An example has been seen, marked with the patent date. No maker's name is marked so we assume it was manufactured by the assignee.

377,645 Feb. 07, 1888 Lateral Lever John H. Shaw New Haven, CT The invention is a screw adjustment for squaring up a blade in the mouth of the plane when the edge is not perpendicular to the sides of the blade. Shaw's patented planes used this patented feature along with 824954.
444,207 Jan. 06, 1891 Pliers Fredrich W. Brocksieper New Haven, CT One jaw of the pliers has a double linkage like the one used in several parallel jaw pliers patents. The other jaw has a freely rocking tip segment so the pliers will adapt to tapering forms as well as those with parallel sides.
445,793 Feb. 03, 1891 Plane Granville W. Wright New Haven, CT This disc-shaped lateral adjuster replaced the horseshoe-shaped lateral adjuster patented by Sargent on this day 445792, which was only used for a short period of time in 1891 on the Sargent #3400 series of transitional planes.
445,792 Feb. 03, 1891 Plane Granville W. Wright New Haven, CT This horseshoe-shaped lateral adjuster was only used for a short period of time in 1891 on the Sargent #3400 series of transitional planes. It was replaced by the disc lateral adjuster patented by Sargent on this day 445793.
493,903 Mar. 21, 1893 Blockplane Lateral Adjuster Granville W. Wright New Haven, CT The invention is the cutter adjustment of the type that has a toothed lever that cooperates with a cutter that has notches on the underside. Commonly seen on Sargent and Fulton blockplanes.

651,057 Jun. 05, 1900 Steel Square Artemas Roberts Normal, NE Table gives lengths of rafters having a defined pitch and a given horizontal run.
Patent date seen marked on a Sargent & Co square and Henry B. Sargent references this patent in his patent 1,102,689.
This patent appears on a Sargent VBM 500CR square (pic 2) with the 1,102,689 patent on the opposite side.
657,391 Sep. 04, 1900 Wrench Thomas H. Brosnihan Livermore Falls, ME The key elements of the patent are the hardened pipe-gripping jaw faces. The pipe-gripping jaw face on the adjustable jaw slides on a keyway-shaped base, and is pressed outward by a spring.
818,472 Apr. 24, 1906 Mouthpiece with Cammed Adjuster Henry B. Sargent New Haven, CT Used on the Sargent #306, #307, #316, #317, #606, #607, #1306, #1307, #1606, #1607, #4306, #4307, #5306, #5307, and #5607 blockplanes. Also used on the #514 low-angle jackplane. The cammed mouthpiece adjuster is distinctive of blockplanes made by Sargent and can help identify which blockplanes they made for others.
824,954 Jul. 03, 1906 Frog Adjuster John H. Shaw New Haven, CT This patent is for a frog adjuster that is functionally equivalent to that on the more famous Bed Rock line of planes made by Stanley 987081. It allows the frog to be adjusted to set the mouth size without removing the cutter. It was another 4 years until Sargent produced the Shaw's patent line of benchplanes in 1910, and production ended in 1918. The benchplanes in the Shaw's patent line are numbered from 7 to 24. These planes also used Wright's patented lateral adjuster 445793. These are well made and collectible planes. Shaw's patented planes used this and 377645.
869,267 Oct. 29, 1907 Tilting Tote John H. Shaw New Haven, CT The Sargent #400 adjustable plane handle. Made with rosewood from 1907 to 1909 and East India mahogony from 1910 to 1916.
960,039 May. 31, 1910 Marking Gage William Potter New York, NY An extremely complicated butt and marking gage with lots of reference faces and points. It could allow fixed or adjustable gain, allowed points to be extended as they were sharpened, and supposedly solved the problem of the gage "tipping" as it marked. One of these appeared on a Patrick Leach tool list.
1,042,139 Oct. 22, 1912 Match Plane Albert A. Page New Haven, CT Used on Sargent's #1066, #1067, and #1068 matchplanes.

1,090,225 Mar. 17, 1914 Plane Albert A. Page New Haven, CT The blade adjusting screw has a pivot to allow the adjuster to swing the blade from side-to-side, providing lateral adjustment to the blade.
1,100,770 Jun. 23, 1914 Rabbet Plane Albert A. Page New Haven, CT Patent primarily claims the extendible frontpiece.

1,104,454 Jul. 21, 1914 Plane William E. Sparks New Haven, CT
1,106,401 Aug. 11, 1914 Saw Vise Albert A. Page East Haven, CT
D46,446 Sep. 22, 1914 Design for a Plane Body Albert A. Page East Haven, CT Used on early models of the Sargent #160, #161, and #162 family of roughing (more commonly known as scrub) planes. Sargent switched to a conventional style of scrub plane with wooden tote and knobs after the cast ones proved to be easily broken in a fall. The #162 model has two cutters side-by-side and is a rare and valuable plane.
1,124,325 Jan. 12, 1915 Bench-Plane Albert A. Page New Haven, CT Sargent #700 series of Automatic planes, known as the Auto-Set planes. Another patent 1151301 also covers these planes.

The Auto-set series have a complex adjuster mechanism that permits the blade to be kept at a constant depth setting before and after sharpening. The blades on Auto-set planes are very thin, and not nearly as robust as regular blades. Replacement blades are very hard to find. Planes in this series were available in sizes 707 through 722, (wherein the last two digits correspond to the length of the plane, similar to Millers Falls), and included a corrugation option. The planes have a distinctive profile with a sloping side. From 1916 to 1924 the tote and knob were East India Mahogany, and from 1925 to 1947 they are listed as mahogany. Dave Heckel in "Sargent Planes - Identification and Value Guide" states that the VBM era (until 1918) Auto-sets have vertical knurling on the screws, and later era planes have diamond-shaped knurling. He reports an early variation having a levercap with a triangular shaped piece to control the cutter depth setting. It has markings of 1-2-3 to indicate depth setting. The levercap acts as a chipbreaker.

The longer models of the Auto-Set planes (Nos. 718 and 722) are equipped with a tilting front knob described as, "high, to give a full grip for the hand and is adjustable so that the user my regulate the position of the Knob, bringing it closer to the handle or further away, as he may prefer. This feature makes it convenient for use by carpenters with long or short arms and allows fhe forward hand plenty of clearance when the Plane is used close up to a projecting surface."

This design precedes the Gage auto-set design, and is sometimes confused with it.
1,149,703 Aug. 10, 1915 Tilting Knob for Auto-Set Benchplanes Bertel F. Vaughn West Haven, CT Used on the larger Sargent Auto-set benchplanes #718 and #722. The planes were patented by 1124325 and 1151301.
1,151,301 Aug. 24, 1915 Bench-Plane William E. Sparks New Haven, CT A refinement of 1124325 for Sargent Auto-Set benchplanes. The Auto-Set series have a complex adjuster mechanism that permits the blade to be kept at a constant depth setting before and after sharpening. See 1124325 for more details on the Auto-Set planes.
1,164,232 Dec. 14, 1915 Plane William E. Sparks New Haven, CT Sargent #4206 and #5206 "light and unbreakable" steel blockplanes produced from 1913 to 1918. It was a day for steel planes as Stanley patented their steel benchplane 1164615 this day as well.
1,166,437 Jan. 04, 1916 Cutter Adjuster for Combination Plane Herbert G. Collins New Haven, CT The double-notched cutter adjustment used on Sargent #1080 and #1085 combination planes.

D137,230 Feb. 08, 1944 Design for a Carpenter's Plane Samuel Oxhandler Flushing, NY Samuel Oxhandler's design for a bench plane was done for the Sargent Company of New Haven, Connecticut. It was later cited as a reference in the design patent for the Millers Falls Buck Rogers plane 159339, which borrows heavily from the original.
