UNITED STATES PATENT EEicE.
DAVID LIPPY, OF MANSFIELD, OHIO.
MEAT-SAWING MACHINE.
SPECIFICATION forming part of Letters Patent No. 599,569, dated February 22, 1898.
Application filed January 11, 1897. Serial No. 618,851. (No model.)
To all whom t may concern:
Be it known that I, DAvID Lrrrv, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio,have invented certain new and useful Improvements in Meat-Sawing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in meat-sawing machines; and the objects of my invention are, rst, to construct amachine for sawing meat with a circular saw and to obviate the necessity of using a knife and saw,
which are now in common use in all butchering establishments; second, to rotate a circular saw by a combination of pulleys and belts to be used in slicing meat; third, to construct the top of the table so that it can be rotated at the will of the operator; also, to divide the top into separate platforms, each part provided with rollers, ratchet mechanism for operating the rollers, and a clamping device for holding the meat in position, each platform can be used for different kinds of meat; fourth, to make a cheap, durable, and efficient means for thepurpose stated. I attain these objects by the mechanism illustrated in the accompanying drawings.
This application is one of a series filed by me of even date herewith for improvements in meat-sawin g machines and bearing, respectively, the Serial Nos. 618,852 and 618,853.
Figure l is a side elevation of my improved meat-sawing machine, showing the general construction of `all the' parts embodying my invention. Fig. 2 is a top view of same, showing more fully the circular platform, the rollers in each division of the same, the clamping device, ratchet mechanism, and combination of pulleys and belts composing the motor. Fig. 3 is a transverse sectional View of circular platform, the modeof pivoting the same in the top of the machine-frame, and the antifriction-rollers, upon which rests the platform. Fig. et is a front view of hand-lever,showing its general construct-ion. Fig.
5 is a'side elevation showing a different motor than the one shown in Fig. 1, the saw operating on parallel guides, the guides and saw adapted to be raised vertically when not in use Fig. 6, a top view of same. Fig. 7 is a front view of lever, showing the mode of at- Jcaching the same at its lower end to the framesill. I have shown this device as a modification of Fig. l. p
Similar letters refer to similar parts throughout the several views.
In the accompanying drawings, A indicates the frame of the machine, which is composed of the legs B B, upper rails C, top D, and sills E. These constitute the frame of the machine.
' F indicates the circular platform; G, the metal pivot-pin, which is secured in the center and upon the under side of the platform. A suitable boxing H is placed in the top D and in which is pivoted the platform F. The
said platform is provided with the metal angle-irons I, so arranged upon the platform that they form recesses J. Each recess is provided with the rollers K, K', and K2. Each roller is journaled in bearings made in the edge of the angle-irons to hold them in position. The roller K' is provided upon one end with a ratchet-wheel L, lever N provided with the pawl N to manipulate the roller. The clamping deviceis composed of the L- shaped bar O, hinged upon its lower end to the angle-iron I. The under side of the horizontal'arm is provided with pointed projections P. The vertical lever Q is also hinged at its lower endy to the angle-iron I upon the opposite side of the platform and is provided with notches R to engage the bar O. Each set of rollers is provided with the clamping device and ratchet mechanism. This description is fully shown in Figs. 1, 2, and 3.
The locking device to hold the platform from rotating is composed of the lever S, placed under the top of the frame and in a line with the center of the circular platform. One end is hinged tothe side rail D of the frame A, the loose end of the lever passing through the rail upon the opposite side of the frame. An upwardly-projecting pin T is secured in the edge of the said lever, the said pin passing through a hole made in the top 0f Athe table and engaging the under side of the circularv platform. The platform rests upon antifriction-rollers U, secured in the top IOO of the frame. Upon one side of the frame and near the end is bolted the standard V. A suitable box-bearing YV is cast in the same and in which is placed a suitable shaft X. Upon the said shaft are secured the pulley Y and balance-wheel Z, provided with the handle B'.
C indicates a bifurcated lever. The lower ends are pivoted upon the shaft D, the said shaft having a bearing in the boxing E', secured upon the outwardly-projecting end of the sill E.
F is a pulley secured upon the shaft D between the boxand one arm of the lever. There is also a pulley G secured upon the said shaft upon the outside of the lever. Two pulleys H and I are secured upon the shaft J', the said shaft journaled in each bar forming the bifurcated lever and near the upper end of the same.
K2 indicates round metal guide-rods. The said rods are placed in suitable bearings formed in the top of the standard V. One end of each is secured in the plates L L, located on each side of the lever. The inner ends are secured in the cross-head M. The said crossheadis bifurcated and is provided withasaw N2, saw-1n andrel O, and pulley P. The pulley is placed within the bifurcation formed in the cross-head.
Vhen the lever C' is placed in position, the pulleys Y and G are in line and provided with a belt Q. The pulleys F and I are also in line; also,the pulleys P and H. Each pair of pulleys is provided with suitable belts R and S to connect the same.
It will be readily seen by those skilled in the art that when the operator takes hold of the handle B and rotates the wheel Z motion is conveyed to the shaft and pulleys D, F, and G' through the belt Q. It is also conveyed to the pulleys Il and I' through the belt R and to the saw N through the belt S.
Then the operator wishes to cut meat, he places a joint upon one set of the rollers and then feeds it forward by the ratchet mechanism until a sufcient quantity of the meat projects past the saw. It is then held firmly by the clamp-levers O and Q. Ile then rotates the saw by the mechanism described and then forces the saw through the meat and bone by the lever C'. As soon as the operator releases the lever it returns to its normal position by the action of the spring T. This description is fully illustrated in the sheet of drawings marked Plate l.
The sheet of drawings marked Plate 2 is shown as a modification of Fig. l, Plate 1, the frame and platform being the same as described. The particular change is in the crosshead and guides and mode of belting. Where three are used in the description given above, two only are used in this device. The crosshead A2 is placed upon the two parallel guides B2. The inner ends are pivoted upon each side of the standard C2. One of the guides is provided with a vertical lever D2, having a spring-bolt fastener E2, which engages in suitable notches formed in the top of the standard C2.
F2indicates connecting-rods, the outer ends secured in lugs formed upon the top of the cross-head, the inner ends to the lever G2.
H2 indicates a foot or support secured upon the outer ends of the guide-rods, and when in position, as shown, the foot rests upon the top of the table I2 to hold the guide-rods parallel with the top of the frame A2.
J2 indicates a belt which passes around the mandrel-pulley K2, thence over the pulley L2, then downward around the pulley N2, up over the pulley M2, forming a communication from one to the other. By pullingdownward upon the lever D2 the guides, foot, and saw are raised in a vertical position to allow the operator to place meat upon the platform.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
