797,321	Aug. 15, 1905	Band-saw machine	Benton Rishebarger	Pittsburgh, PA	"The object of this invention is the provision of novel means for adjusting the saw whereby right and left hand bevels or angular cuts may be made." The innovation is a mechanism for a tilting-frame bandsaw.
798,519	Aug. 29, 1905	Adjustable band-saw	Edward Tiers Manning	Knoxville, TN	"The present invention relates to band-saws where the frame carrying the saw-blade is adjustable, so as to set the saw at different oblique positions in order to adapt it to cut bevels and any desired angles. It is desirable where the saw-blade is adjustable in this way that the work-supporting table through which the saw passes should also be adjustable to follow the different positions of the saw; and the present invention relates specifically to means for effecting the adjustment of the saw-carrying frame and also to means for automatically effecting an adjustment of the table to correspond with the different positions of the saw."

1,134,738	Apr. 06, 1915	Guard for woodworking machines	Leroy J. Halverstadt	Leetonia, OH	Guard is for a jointer or planer. It is not known to have ever been produced by Crescent Machine Co.
1,147,473	Jul. 20, 1915	Cutter-head	Clinton G. Wilderson	Leetonia, OH	This invention is a variation on the design in patent 943,540; the changes are aimed at making the head less expensive to produce, and to allow the holding bars to be removed without having to pull them out through the end of the cutter-head. This design was a dead end, being superseded by that in patent 1,153,910. Nonetheless, it is believed to have been used on Crescent jointers and planers.

1,471,993	Oct. 23, 1923	Mortising and boring machine	Clinton G. Wilderson	Leetonia, OH	This invention is improved in patent 1,619,049, and was used in the Crescent mortiser.
1,478,956	Dec. 25, 1923	Exposure meter	Elmer Harrold	Leetonia, OH	Invention is a photographic exposure meter, and is of interest because the inventor was a co-founder of Crescent Machine Co.
1,496,035	Jun. 03, 1924	Combined guard and blower	Enos E. Thomson	Cleveland, OH	It appears that this invention was never actually produced by Crescent.
1,518,982	Dec. 09, 1924	Weighing scale	Elmer Harrold	Leetonia, OH	Invention is of interest because the inventor is a co-founder of Crescent Machine Co. The weigh scale itself is a postal scale and is ingenious for its simplicity and very low cost.
1,528,592	Mar. 03, 1925	Combined guide and support for bandsaws	Clinton G. Wilderson	Leetonia, OH
1,560,748	Nov. 10, 1925	Work clamp for woodworking machines	Clinton G. Wilderson	Leetonia, OH

1,789,125	Jan. 13, 1931	Cutoff gauge for saws	Clinton G. Wilderson	Leetonia, OH	Seen in 1926 catalog on the Crescent no. 12 saw table. Seen in a 1930 catalog on the No. 13 and No. 15 saw tables as well.
1,802,800	Apr. 28, 1931	Router attachment for woodworking machines	Clinton G. Wilderson	Leetonia, OH	Invention is intended as an accessory for the Crescent Universal Variety Saw, patent 1,846,295. This accessory appears to have never been produced: it has never been seen in any Crescent literature.
1,830,151	Nov. 03, 1931	Dust collector and guard for saws	Clinton G. Wilderson	Leetonia, OH	The guard is for the Crescent Universal Variety Saw (what we would call a radial arm saw), patent 1,846,295. This guard is shown on the cover of a 1927 Crescent circular for the Universal Variety Saw.
1,846,295	Feb. 23, 1932	Woodworking machinery	Clinton G. Wilderson	Leetonia, OH	This is the Crescent Universal Variety Sawâ€”a radial arm sawâ€”which is described in the patent as "a machine of more or less light construction intended for doing light work, and especially adapted for use by contractor where a light portable saw is required in the erection of a building or other construction." Patent 1,830,151 describes a blade guard for this saw.
1,857,905	May. 10, 1932	Control mechanism	Clinton G. Wilderson	Leetonia, OH	Inventor Wilderson was a co-founder of the Crescent Machine Co. He was deceased by the time this patent was issued. The invention itself is a means of quickly stopping a machine spindle. A 1930 Crescent catalog shows this feature on their single-spindle shaper.
2,032,233	Feb. 25, 1936	Band saw guide	Herbert E. Tautz	Milwaukee, WI	Seen on the Crescent/Delta 20-inch Band Saw. Since Herb Tautz is the patentee, it is clear that this machine is actually a Delta creation, not a Crescent creation. The patent number has also been seen on a Delta No. 768 10" band saw, along with patent 2,040,718; those patent numbers have also been seen on a No. 890 14" band saw.
2,040,718	May. 12, 1936	Trunnion	Herbert E. Tautz	Milwaukee, WI	Seen on the Crescent/Delta 20-inch Band Saw.
