Patent Number	Date	Title	Name	City	Description
1,229,401	Jun. 12, 1917	Drill gearing	Alonzo Galloway Decker	Orangeville, MD	"The primary object of this invention is the provision in a portable drill of a variable speed disk drive between the power motor of the drill and the chuck spindle or such other member as drives the drill directly. Another object of the invention is to utilize an element of this disk drive as a fan for creating an air draft to cool the motor."

1,463,305	Jul. 31, 1923	Pumping apparatus	Alonzo Galloway Decker	Baltimore, MD	Of interest because it is an early patent to Mr. Black and Mr. Decker. The patent is assigned, by mesne assignments, to the Maryland Trust Co. It is likely that the original work was done for the first, Baltimore-based, incarnation of Black & Decker, which appears to have encountered financial difficulties and been reborn a couple of years later as a Towson-based business.

1,492,095	Apr. 29, 1924	Electrically-driven tool	Alonzo Galloway Decker	Baltimore, MD	An improvement to patent 1,245,860; the improvement is to the on-off switch to address a problem with unequal contact force in a pair of contacts.

1,574,020	Feb. 23, 1926	Electric-cord protector	Alonzo Galloway Decker	Baltimore, MD	The invention is the molded-rubber strain relief for the electrical cord. Previous strain reliefs had been made either from coiled wire or a uniform-cross-section length of rubber hose. Messrs. Black and Decker had the idea of using a rubber strain relief similar to a length of rubber hose, but of decreasing cross-sectional thickness so as to distribute the bending forces over a length of the cord.

1,633,389	Jun. 21, 1927	Electric tool	Walter Stumpf	Baltimore, MD
1,699,870	Jan. 22, 1929	Portable tool	Alonzo Galloway Decker	Baltimore, MD	"The object of the present invention is to product a tool which can be used as a combined screw driver or socket wrench and drill." The innovation is a clutch that can be disabled when the tool is used as a drill.
		Portable tool	Samuel Duncan Black	Baltimore, MD
1,702,245	Feb. 19, 1929	Electrical connection for portable electric tools	Alonzo Galloway Decker	Baltimore, MD	Improved means of electrically connecting the cord to the drill. The improvements are to extend the service life of the cord, and ease replacement of the cord when necessary.

2,038,422	Apr. 21, 1936	Bench drill stand	Alonzo G. Decker	Baltimore, MD	An example is seen labeled as a "Van Dorn No. 60 Bench Drill Stand". The same label gives "The Van Dorn Electric Tool Co. Towson, MD., U.S.A. Div. of Black & Decker Mfg. Co."
2,155,082	Apr. 18, 1939	Portable electric tool and casing	Alonzo Galloway Decker	Towson, MD	This is the Black & Decker "Shorty" drill. The patent drawings suggest that it was inspired by a need in the aircraft industry to drill rivet holes in tight quarters.
