Description
UNITED STATES PATENT l OFFICE.
IRA CURTNER, OF DAYTON, OHIO, ASSIGNOR TO CEAS. A. GMP AND EDWIN S. FORGY, OF SAME PLACE.
'IMPROVEMENT IN sToNE-TooLS.
Spccl ation forming part of Lettere Patent No. 146,05 l, dated December 30, 1873; application filed September 20, 1973.
Fo all whom it may concern:
Be it known that I, IEA GURTNER, of Dayton, in the county of Montgomery and State of Ohio, have invented a new and valuable Imand it consists in the construction and novel arran gement of the devices for securing 1n "place a removable blade with a recess, as hereinafter more fully described.
In the accompanying drawings, the letter A designates the handle. B indicates the removable blade, tapering on its upper or lower surface, or both of them, toward the ends from the central portion a, which is provided in its under side with the central recess b. G designates a ferrule, provided with a socket to' receive the end or tenori of the handle A, a screw or key, c, being usually employed to secure the connection. The upper end of the ferrule is provided with a screw-thread, d, extending to a shoulder, c, and designed to engage with the shank-socket of the T-coupling. At the end of the threaded portion a small boss er projection, h, is provided to enter the recess b of the blade when the ferrule is screwed 4 home. l) represents the T-coupling. This consists of the shank-socket k, having a female screw-thread, and the blade-socket l, rectangular in form, and arranged at right' angles with the axis of the shank-socket. rEhe bladesocket is of greater diameter than the shanksocket usually, and its upper or outer wall m is designed to extend longitudinally for some distance on each side of the shank-socket to receive the parallel central portion or body a of the blade, thus materially strengthening the same and deadening the vibrations, as the blade is, by the pressure of the boss h of the ferrule, when the latter is screwed home, brought rml y in contact with said wall. When the parts are screwed together, the end of the shank-socket is designed to t the shoulder e of the ferrule neatly and evenly, so that the joint of the cylindrical surfaces of the "two parts will be hardly perceptible. `At the same time the frictional contact serves to obviate, in great measure, the tendency of the parts to become loose by unscrewing. The blade-socket is designed to fit the blade neatly on each side, but loosely on .the lower surface, so that it can be easily and quickly removed in either direction.
What I claim as new, and desire to secure by Letters Patent, is
The combination, with the T-coupling having the blade socket b, and shanksocket k, of the screw-ferrule C, provided with the boss h, to enter a central recess in the blade, substantially as specied.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
IRA OURTNER.
