UNITED STATES PORTER E. GUMMINGS, OF SANFORD, MAINE.

IMPROVED KNIFE-CARRIER.

Speeieation forming part of Letters Patent No. 58,992, dated October 23, 1866.

To all lwhom. it may concern:

Be it known that I, lon'rnn E. CUMMINGS, of Sanford, in the county of' York and State of Maine, have iliade a new and useful invention having reference to Knife-Carriers of Sole-Cutting lilachines,and particularly to that as used in the machine described in No. 43,958 of United States Patents; and I do hereby declare the same to he fully described in the following specification and rel'nescnted in the accompanying drawings, ot' which- Figure l denotes a side elevation, and Fig. 2 an edge elevation, ot' a knit'e and its carrier as formed in one piece, sneh being the inode heretofore adopted ot' constructing the same, my invention being an improvement thereon. Fig. 3 is a top view, Figs. 4 and 5 side elevations, Fig. (i an edge elevation, Fig. 7 a vertical and longitudinal section, and Fig. 8 a vertical and transverse section, of a knife and its carrier made in laccordance with my invention, by which the knife and its carrier are in two separate parts, and the carrier is formed with asocket and a rabbet to receive the knife, and is provided with a clamp or set screw to hold it in such socket.

After the knife-carrier has been once fixed and adjusted in the machine, its removal for the purpose of sharpening the knife often renders it dit'licult or requires a considerable expenditure of time and labor to readjust it properly. It is therefore desirable always to keep the knife-carrierin its proper place in the machine, and for this purpose I make it separate from the knife, and with a socket and a rahbet to receive the shank of the hinge.

In Figs. 3, 4, 5, G, 7, and 8, A represents the knife, and B the carrier; e, the journal; b, the socket; c, the rabbet, and (Z the chimpscrew ofthe carrier. The knit'c is to be made with a shank, c, to tit to and extend down into the socket. The screw screws into the carrier and against the knit'e. The rabbet goes across the socket, and allows the face ot' the knife to rest closely against the edge of the pattern; It also constitutes a shoulder to rest against the lower surface of the pattern and as a means ot' preventing the edge of the knife from cutting into the edges ofthe pattern.

Vith my invention the knife can be easily removed from the carrier without the necessity otq removing the latter from the machine.

I claim- The improved knifecarrier made substantially as described-viz., with the knife-shank socket and the rabbet arranged in it as set forth, the said carrier heilig provided with a set-screw, or equivalent means ot' xing the knife-shank in the socket.

PORTER E. CUMMINGS.
