Patent Number	Date	Title	Name	City	Description
1,102,018	Jun. 30, 1914	Power-driven handsaw	Ethan I. Dodds	Central Valley, NY	This patent is most notable for its blade guard, riving knife, and built-in fence. The assignee manufactured bolts and enamel-ware, though they were assigned a number of patents related to handheld power tools and granted to Ethan I. Dodds; a search failed to turn up any evidence that Kerner Mfg. ever made power tools. This patent date was seen on a pneumatically-powered circular saw from Ingersoll-Rand Co.; this patent seems to be the most likely match. This patent date was also seen on a circular saw from Skilsaw, Inc.; the other patent dates on the saw spanned 1920 to 1925, "other patents pending". The inventor, Ethan I. Dodds, promoted himself as the most prolific inventor in the USA aside from Thomas Edison, claiming that he was granted over 2000 US patents. The actual count was more like 320.
1,512,296	Oct. 21, 1924	Rotary cutting implement	Edmond Michel	New Orleans, LA	This is the original Skilsaw. Inventor Edmond Michel reportedly was trying to ease the cutting of sugarcane; the patent specification itself is vague as to its uses, but mentions slaughterhouse applications.
1,540,388	Jun. 02, 1925	Portable saw	John M. Crowe	Covington, KY	This patent date was seen on a pneumatically-powered circular saw from Ingersoll-Rand Co. This patent date was also seen on a circular saw from Skilsaw, Inc.; the other patent dates on the saw spanned 1914 to 1925, "other patents pending". An article in the May 1927 "Railway Engineering and Maintenance", page 218, describes Ingersoll-Rand Co.'s "New Air-Driven Portable Hand-Saw". The saw "consists essentially of an Ingersoll-Rand three-cylinder type air motor, a circular saw blade and a Crowe safety saw guard, together with suitable hand grips..." The saw was intended for cutting wood, soapstone, bakelite, wall-board, cable and copper. A variety of blades were available. The speed of cutting was claimed to be 20 times as fast as by hand-power. It was available in sizes to accommodate blade diameters of 6, 8 and 12 inches.
1,708,345	Apr. 09, 1929	Portable power-driven tools	Joseph F. Haas	Forest Park, IL	An example of a Skilsaw Model E worm-drive saw bearing this patent number is reported.

1,821,624	Sep. 01, 1931	Sandpapering machine	Arthur N. Emmons	Nedrow, NY	A Skilsaw Model A handheld belt sander was seen, marked as "Licensed under U.S. Pat. 1,821,624â€”others pend."
2,082,806	Jun. 08, 1937	Electric control lock	Edmond Michel	New Orleans, LA	This patent is of interest because the inventor previously patented a handheld circular saw, 1,512,296, and then founded a company, Electric Hand Saw Co., to make it. That company later became Skilsaw, Inc. and then Skil, Inc. Inventor Michel received other patents that were assigned to Larmloc Corp.: 2,136,307, 2,136,858, and 2,136,859. These are all the patents that were ever assigned to this company, so there is a good chance that Michel was at least a part owner.
D114,970	May. 23, 1939	Design for an electric hand saw	Bolton Sullivan	Winnetka, IL	The patentee was the founder and president of Skilsaw, Inc., and this patent covers the "look" of their iconic worm-drive saw.
D123,425	Nov. 05, 1940	Design for a sanding machine	John H. Willmarth	Wilmette, IL
2,272,273	Feb. 10, 1942	Sanding machine	Leonard E. Parker	Cary, IL	This distinctive "locomotive" styled sander was the Skil Sander Models 9, 323, 324 and 325;the 324 was earlier known as the BR. We have also seen this patent number on a "Thor Torpedo-plane" sander from Independent Pneumatic Tool Co., which would change its name to Thor Power Tool Co. It is likely that the sander was made by Skil and was rebadged by Independent Pneumatic: the Thor Torpedo-plane was very nearly the same as a Skil Model 9.
2,390,544	Dec. 11, 1945	Handle	Thomas Lamb	New York, NY	This patent number was seen on a radial arm saw from Skilsaw, Inc., along with the notation "Lamb wedgelock handle". "This invention relates to handles or hand grips adapted for use in connection with many articles which are lifted, pulled, pushed or otherwise manipulated by hand, as for example, luggage, hand tools, flat irons, firearms, coffee pots and many other articles. It is an object of the invention to provide a handle so designed with relation to the average human hand and arm as to provide comfortable, natural gripping surfaces which tend to distribute and equalize gripping tensions and thereby relieve strain and reduce fatigue in use."
D147,502	Sep. 16, 1947	Design for a floor sanding machine or the like	Frank J. Koenig	Chicago, IL
2,545,453	Mar. 20, 1951	Rotary pneumatic tool	Frithiof P. Forss	Auror, IL	This patent number was listed in a Skil Corporation catalog.
2,561,093	Jul. 17, 1951	Internal-combustion rammer	Emmons R. Boddinghouse	Evanston, IL	This patent number was listed in a Skil Corporation catalog. See also patents 2,031,535 and 2,090,842.
		Internal-combustion rammer	Victor W. Breitenstein	Chicago, IL
2,564,350	Aug. 14, 1951	Machine tool	Harry R. Wilson	Waterloo, IA
2,566,183	Aug. 28, 1951	Portable power-driven tool	Frithiof P. Forss	Aurora, IL	This patent number was listed in a Skil Corporation catalog.
2,567,095	Sep. 04, 1951	Portable tool	Allen Benjamin	Chicago, IL	This patent number was listed in a Skil Corporation catalog.
2,600,279	Jun. 10, 1952	Portable power-driven planer	Henry A. Spitzley	Portland, MI	The patent covers depth regulation for a handheld portable planer; this patent number was seen on a Skil 100 portable planer.
2,607,559	Aug. 19, 1952	Valve for pneumatic riveting hammers	Ernest H. Forss	Rockford, IL	This invention "has for its principal object the provision of a slow-hitting hammer having such fine control of air delivery that a single light rap may be given the rivet set, thus better adapting the tool to use in airplane manufacturing plants where the light rap serves as a signal from the operator on the outside of an airplane fuselage to his or her helper inside who backs up the rivets which rivet will next be hammered, thus reducing to a minimum any likelihood of the relatively frail aluminum wall that is being riveted being dented, or even punctured, and requiring removal of a large panel as a result of the failure on the part of the helper to back up the proper rivet." This patent number was listed in a Skil Corporation catalog.
2,618,459	Nov. 18, 1952	Pneumatic hand tool valve and trigger lock	Frithiof P. Forss	Auror, IL	This patent number was listed in a Skil Corporation catalog.

2,681,673	Jun. 22, 1954	Drill bit	Bruce A. Mackey	Libertyville, IL	This patent number was listed in a Skil Corporation catalog.
2,705,980	Apr. 12, 1955	Portable power driven reciprocating and oscillating cutting tool	Walter A. Papworth	Syracuse, NY	This patent number was listed in a Skil Corporation catalog. See patent 2,842,170 for more information on this invention.
2,752,965	Jul. 03, 1956	Drill bit construction	Bruce A. Mackey	Libertyville, IL	This patent number was listed in a Skil Corporation catalog.
2,775,272	Dec. 25, 1956	Portable power reciprocable cutting tool	Walter A. Papworth	Syracuse, NY	This patent number was listed in a Skil Corporation catalog.

3,270,595	Sep. 06, 1966	Offset Drive Attachment with Reversing Means	Emery L. Hall	Hinsdale, IL	Greist, Lockwood, Greenawalt & Dewey - patent attorneys This invention relates generally to drive attachments of the type which permit running a fastener from a power tool with the latter in offset relation from the fastener, and more particularly to a new and improved drive attachment of the type which permits a fastener to be run in either direction without changing the relationship between the drive attachment and the fastener. It is a primary object of the present invention to provide a new and improved drive attachment which includes unique pawl construction for reversing the direction of rotation of the output member of the attachment and thereby reversing the direction of rotation of the fastener being run. Another object of the present invention is the provision of a new and improved drive attachment which includes a pair of drive pawls and a dual action stop pawl which may be selectively positioned alternately to block one of the drive pawls and cooperate with the other for rotating the output member in one direction and to block the other drive pawl and cooperate with the first mentioned drive pawl for rotating the output member in the other direction. Still another object of the present invention is the provision of a new and improved drive attachment which includes resilient means connected with both drive pawls for urging them in engagement with the toothed member, which resilient means also cooperate with the blocked drive pawl and the stop pawl for rockably urging the latter in engagement with the toothed output member.
