SHARPENING ATTACHMENT FOR MEAT-CUTTERS.
SFEGIFIGATION formingpart of Letters Patent No. 680,148, dated August 6, 1901.
Application filed September 20, 1899. Serial No. 731.088. No model.)
T0 at whont it may concern:
Be it known that I, CABEL B. HOPKINS, a citizen of the United States, residingin Phila= delphia, Pennsylvania,have invented certain for Beef-Shaving Machines, of which the following is a specification.
The object of my invention is to sharpen the blade of a machine for cutting or shaving meat, 850., having an oscillating knife, without removing the blade from the machine, and this objectI attain in the following manner, reference being had to the accompanying drawings, in which- Figure l is an end view of a beef-shaver with my improved blade-sharpener attached.
the machine, showing the sharpener shifted clear of the blade. Fig. 3 is aside"view,partly in section, showing the sharpener resting against the blade; and Figs. 4 and 5 are detached perspective views showing the details of the sharpening mechanism.
A is the frame of the machine.
B isthe knife-frame, pivoted at b to the upper portion of the frame A.
A is a V-shaped trough in which the beef to be shaved is placed. The knife is so pivoted that it shears past the end of the trough and cuts the beef as it is fed forward by the feed mechanism of the machine.
My invention does not relate to the construction of the beef-shaving machine, and the above is simply the description of the form of machine to which my invention may be applied.
In machines of the type described above it is a difficult matter to sharpen the knifeblade. Heretofore this has been done by hand, either by drawing the knifeframe back as far as it will go and sharpening the blade while in that position or the blade was removed and sharpened.
My invention relates to sharpening mechanism attached to the machine, which can be throwninto or outof operation without interfering materially with the working of the maachine,and which will accurately sharpen the blade.
D is a block secured to the base of the frame A, but which may form part of the frame in some instances. Pivoted at d to this block is a carrier-lever D, to one arm of which is attached a sharpener d of any suitable form, being shaped in the present instance similar to an ordinary butchers steel.
A spring 0, secured to the block D, rests against the other arm of the lever D and tends to keep the sharpener d in contact with the blade during the time the device is 6:: in position to sharpen the blade, thus insur ing a yielding contact, and when the device is thrown out of gear the spring tends to keep it out of the path of the knife-frame.
E is a shifter pivoted to the frame A at e, and is shaped to conform to the outline of the frame. This shifter has a projection c, which can be moved to either side of the frame, and preferably rests in recesses a a formed in the frame. There is a sufficient 7o spring in the metal of the shifter to allow it to be set in either position. On the shifter is a stop 6 against which strikes the knifeframe B when it is moved forward, so as to limit the forward movement of the knifeframe when the sharpener is in position to sharpen the blade, but when the shifter is moved back, so as to allow the sharpener to clear the blade, the stop is also clear of the knife-frame.
I claim as my invention 1. The combination in a shaver or cutter for meat, &c.,of a knife havinga beveled edge with a sharpening device constructed to be brought into yielding contact with the beveled portion of the knife, and means for normally holding said device on the side of the blade opposite to that having said beveled edge and out of the path thereof, substantially as described.
2. The combination in a shaver or cutter for meat, 850., of a knife having a beveled edge, a pivoted sharpener adapted to rest against said edge, a spring tending to keep the sharpener in contact with the blade when 5 the edge thereof is being sharpened, said spring normally tending to keep the sharpener out of the path of the blade, substantially as described.
3. The combination in a shaver 0r cutter for meat, 85.0., of, a knife having a beveled for meat, &c., having an oscillating blade, a pivoted lever carrying a sharpen-er, and a pivoted shifter for said sharpener, said shifter I 5 having a stop to limit the movement of the blade, substantially as described.
In testimony whereof I have signed my l name to this specification in the presence of two subscribing Witnesses.
CABEL B. HOPKINS.
