WILLIAM A. HULBERT, OF BROOKLYN, ASSIGNOR TO MERWIN, HULBERT & CO, OF NEW YORK, N. Y.
DESIGN FOR CYLINDER FOR REVOLVERS.
Specification forming part of Design No. 9,386, dated July 11, 1876; application filed June 27, 1876. [Term of Patent 14 years.]
To all whom it may concern:
Be it known that I, WILLIAM A. HULBERT, of Brooklyn, Kings county, State of New York, have invented a Design for the Cylinder of a Revolver Fire-Arm, of which the following is a specification:
The nature of my design is fully represented in the accompanying drawing to which reference is made.
A represents the body of the cylinder. At each end its outline is a true circle, and the body between the ends is a true cylindrical figure, except that its surface is diversified by oval recesses or depressions a, corresponding in number to the chambers in the cylinder, located intermediate of radii drawn from the center of the cylinder through the centers of its chambers. The recesses or depressions have the form of the outer curved surface of a segment of a cylinder rounded at the ends, and are formed in the surface of the cylinder, with the long axis of the oval parallel to the axis of the cylinder, as plainly represented in the accompanying photographic illustration. They are formed midway, or about midway, between the ends of the cylinder, but do not extend entirely to its ends, thus leaving the said ends true circles, and the body between the ends and the recesses truly cylindrical.
I am aware that the external curved surface of cylinders of revolver fire-arms have been diversified by excavations or depressions; but all such excavations, so far as I am aware, have been made the entire length of the cylinder, thus cutting into scallops or circular notches the perimeters of the ends of the cylinder. Such recesses, while they contribute nothing to the beauty or grace of the design, are objectionable, as interfering somewhat with the mechanical operation of the cylinder.
My design, on the contrary, imparts to the cylinder a light and graceful appearance, very pleasing to the eye, while it leaves the ends of the cylinder intact for the proper performance of their functions.
What I claim as my invention is–
A design for a cylinder of a revolver fire-arm, in which the cylindrical surface is diversified by a number of oval recesses or depressions, located midway, or nearly midway between the ends of the cylinder, as described, leaving the periphery of said ends unbroken circles, as described.
Witness my hand this 20th day of June, 1876.
WM. A. HULBERT.
