Patent Number Date Title Name City Description
1,531,357 Mar. 31, 1925 Micrometer caliper Herbert E. Tautz Milwaukee, WI The inventor Tautz, who went on to found Delta Manufacturing Co., is described as a citizen of Germany.

1,749,114 Mar. 04, 1930 Toy sewing machine Herbert Erich Tautz Milwaukee, WI This was marketed as the "American Girl" sewing machine, a companion piece to the "American Boy" scrollsaw. Those two toys were the first products of what became the Delta Manufacturing Co. According to correspondent Thomas H. Fehring, "Delta eventually sold the right to manufacture the device to the National Sewing Machine Company in Belvedere Illinois. National continued making the American Girl toy sewing machine into the 1950s, coming out in additional colors and with other versions of the machine called 'Eldredgette' and 'Stitchwell.'"

2,009,304 Jul. 23, 1935 Combination guard and support for jointer fences Herbert E. Tautz Milwaukee, WI "This invention relates to a combination guard and support for a jointer fence. More specifically it relates to a device for guarding that portion of the jointer cutter which is not being used for a given setting of the jointer fence, namely, ordinarily the portion to the right of the fence. Another object is to provide means to support the jointer fence at a point remote from the front end thereof, whereby the yielding or play of the jointer fence may be minimized, said support, nevertheless, permitting the fence to be tilted freely to any desired angle with the jointer tables. A further object is to provide such combined guard and fence support, which need not be removed from the machine regardless of the position of adjustment of the fence, so that no portion of the cutter knives will ordinarily be exposed, the new guard cooperating with the ordinary guard, which protect the left hand or active portion of the knives, to secure full protection of all parts of the cutters."
2,015,734 Oct. 01, 1935 Sectional jointer fence Herbert E. Tautz Milwaukee, WI "The invention relates to jointers and more particularly to jointer fences. An object of the invention is to provide a jointer fence which is so constructed that the lower edge thereof can be kept close to the front and rear tables of a jointer regardless of the relative adjustment of the tables for regulating the depth of cut. Another object of the invention is to provide a jointer fence of this character capable of being mounted on the adjustable front table of the jointer."

2,069,395 Feb. 02, 1937 Safety shield Herbert E. Tautz Milwaukee, WI This is the patent for the Delta Twin-Lite grinder shield. "The invention relates to safety shields for grinding wheels and the like, and has for an object to provide a safety shield which will effectively guard a user of a grinding wheel from flying particles and afford shadowless illumination of the wheel and work viewed through the shield." This is done by using a pair of lamps, one on either side of the grinding wheel.
This patent was the subject of at least two lawsuits: one launched by Delta against Essley Machinery Co., and the other launched by The Stanley Works against Delta's successor, Rockwell Manufacturing Co. The first lawsuit was decided in favor of Delta. The second lawsuit concerned this patent's Claim 6: "A safety shield comprising a housing having a top wall and a skirt, said top wall having an opening, a transparent panel for said opening, a transparent panel for said opening for viewing work therethrough, and means carried by said housing for directing light onto the work from regions adjacent the opposite sides of said panel and within said skirt". This claim was disallowed as being an obvious extension of the prior art, especially patent 1,633,412.

2,085,131 Jun. 29, 1937 Jointer fence Herbert E. Tautz Milwaukee, WI This end-locking mechanism for a jointer fence was used by Delta on their 6-inch jointer, and was apparently also used by Walker-Turner, because the patent number is listed in a Walker-Turner jointer manual.

2,168,282 Aug. 01, 1939 Circular saw Herbert E. Tautz Milwaukee, WI This patent is quite interesting because it shows what is believed to be a proto-Unisaw. This patent covers a tilting-arbor mechanism that is somewhat similar to the mechanism ultimately used in the Unisaw. The actual Unisaw mechanicals were covered in patents 2,265,407 and 2,265,408.
"It has been usual in circular saws of the tilting arbor type to place the saw arbor and driving motor therefor on the same tiltable support, which has subjected the support and its pivotal mounting to a relatively heavy load. In other cases, the saw has been belt-driven from a counter-shaft or non-tilting motor, necessitating twisting of the driving belt when the arbor is tilted. An object of the invention is to provide a circular saw of the like in which the cutter arbor and a driving motor therefor are carried on separate tiltable supports, so as to relieve the arbor mounting of excessive weight and torsional stresses, both supports being tiltable together to maintain the same relative position of arbor and motor." Other objectives were to mount the motor at the rear of the saw, to keep belt tension constant, and provide a trunnion which is of "strong but inexpensive construction."

2,180,079 Nov. 14, 1939 Convertible sawing and abrading machine Leighton A. Wilkie Glencoe, IL Bandsaw that can be converted to a "filing or abrading device, or a polishing machine, as the occasion may require."
This patent number was listed in a Delta catalogue.
2,193,946 Mar. 19, 1940 Extension control means for tool guides Herbert E. Tautz Milwaukee, WI This patent covers the lower saw guide mounting for the Delta 14" bandsaw and Crescent/Delta 20" bandsaw. This is an improvement on patent 2,108,086; the lower saw guide itself is covered by patent 2,032,233.

2,211,050 Aug. 13, 1940 Woodworking machine John E. Boice Toledo, OH "The invention is directed particularly to the problem of easy shifting of the belt drive so as to change the speed ratio between the driving and the driven pulley. To this end, it provides a motor that is swingingly mounted on the frame of the press in such a manner that gravity, i.e., the weight of the motor, keeps the belt taut, and which may be moved to a position to release the belt by simply grasping a lever and pulling toward the operator."
