COMPUTING CHEESE-CUTTER.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed September 27, 1904. Serial No. 226,184.

To all whom it may concern.-

Be it known that I, BARTON W. SABIN, a citizen of the United States, residing at A11- derson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Computing Cheese-Outters, of which the following is a specification.

This invention relates to improvementsin machines for computing and cutting cheese, the object being to provide a machine that will measure the right fractional part of the cheese to be given to a customer at a certain price-as, for example, the correct size of a slice of twelve-pound cheese for ten cents or any other money denomination called for by the customer.

The object is to provide a simple construction and one that will be positive and accurate in its operation, durable, and readily understood by a person of ordinary intelligence.

I accomplish the objects of my invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top plan view of my complete invention set to measure a five-cent slice in a twelve-pound cheese; Fig. 2, a view in side elevation of the device illustrated in Fig. 1; Fig. 3, a detail in top plan view of my improved machine with the knife, lever, bracket to support the lever, and the table or platform to receive the cheese removed and showing some of the remaining parts broken away to illustrate the under-side construction. Fig. 4 is a side elevation and partial vertical section of my invention.

Like characters of reference indicate like parts throughout the several views of the drawings.

5 is the base-plate of my machine, which is of annular form, supported upon the legs 6'. It has a rear extension 7 to support a bracket or standard 8, which may be integral therewith or formed separately and bolted thereto. This standard preferably comprises two parallel arms. 9 is a lever or handle having a bifurcated end 10, which is placed between the two arms of the standard 8 and is there secured by means of bolt 11. Secured to the handle 9 is the knife 12. The annular base-plate 5 has the radial arms 13, which support a central hub 14. The hub 14 has a vertical opening, as shown.

15 is an annular turn-table plate having the radial arms 16, which support a central hub 17. The outside diameter of this hub is such as to make a close fit in the bore of hub :23 at each of .its

14, in which said hub 17 is inserted. This hub 17 also has a vertical perforation or bore. 18 is the platform upon which the cheese to be measured and out is placed. It will preferably be made out of wood, but will have the centrally-located under-side pin 19 of metal. This pin 19 corresponds in diameter to the size of the bore of the hub 17 and will be seated in said bore when the table 18 is in its operative position. The table 18 will have the customary knife-edges 20 projecting radially from its top surface to enter the .base of the cheese for the purpose of compelling a positive movement of the cheese with the base. The position of the lever or handle 9 previously referred to is such with relation to the platform 18 that its knife 12 upon the raising and lowering of the lever will travel in a vertical plane through the axis of rotation of said table.

Bolted or otherwise securely fastened to the under side of the turn-table l5 is a metal ring 21, having the ratchet-teeth 22 formed on its inner face. Mounted around the hub 14, between the ring 21 and base-plate 5, is the lever 23. Pivotally secured to one of the arms 13 is the lever 24, the outerend 'of which extends toward the front of the ma chine past the limits of the plate 5. Connecting the lever 24 with the lever 23 is the link-bar 25, which is clearly shown in Fig. 3. By the construction thus shown and described a movement of the lever24 back and forth will correspondingly oscil late the lever 23. Mountedupon the lever ends are the pawls 26 26, which engage the ratchet-teeth 22 of ring21.

The pawls are pressed into engagement with said ratchet-teeth by means of the springs 27, as shown, whereby when the lever 24 is oscillated the lever 23 will be moved in a manner to cause its pawls to engage the teeth of ring 21, thereby rotating the ring and causing the turn-table 15 and platform 18 to move ina rotary manner, which will swing the cheese resting upon the platform rotarily around the axis of the table and bring it under the vertically-reciprocating cutting-knife.

Mounted on one of the radial arms 13, preferably the rear one of said arms on account of being less inthe way there, is a third pawl 28, which is pressed by a s ring into constant engagement with the rate et-teeth 22 and is for the purpose of acting as a brake or stop to control and regulate the .movement of the turn-table and especiallyto prevent the back will preferably comprise a ably by means of bolts 31, as shown in Figs. 2

and 4, is the extension 32, which has the diagonal slot 34 adjacent to its right end. The

slot 34 forms the seat'for pin 35, which is ad- 'ustable longitudinally of said slot. The pin bolt having a head at its lower end, which bears against the plate on each side of the slot and extending up through the slot has a threaded end, on which a nut with a milled head is screwed. Extending longitudinally of said plate 32 is the slot 36, in which is seated the adjustable stop 37, which in construction and operation is similar to the pin 35 just described. The

function of the slots 34 and 36 and their adjustable pins 35 and 37 will be better understood by a description of the operation of the several parts. With the pin 35, for example, at the lower and outer end of the slot 34 and the pin 37 at the inner or adjacent end of slot 36 the throw of lever 24 will be limited in both directions by contact with said pins, and the distance between the said pins when set at the positions just specified will give a rotary movement to the table, and therefore to the cheese carried by it, just sufficient to cause a cheese weighing twelve pounds and valued at five cents per pound to move under the cutting-knife just far enough to produce a slice of cheese if cut off by the knife one pound in weight, and consequently five cents in value. The direction of the oblique slot 34 with relation to the radial plane of the cutting-knife is such that when the pin 35 is moved a distance in said slot marked as 36 on the drawings at the end of said slot the lever 24 contacting with said pin at'said point 36 will be arrested in its movement and on its return to the pin 37 will move the table 'ust far enough to cause a thirty-six-pound cheese placed upon said table to move under the knife a distance that will produce a slice of cheese of the value of five cents when out off at that position of the table. Cheese of weights between twelve and thirty-six pounds, the extremes selected in this illustration, will be gaged by placing the pin 35 at proportionate points between these extremes here named, which points are readily ascertained by a mechanical subdivision of the distance between said extremes and will preferably be marked in the plate 32 at the side of the slot in the manner shown in the drawings.

Multiples of the first five cents worth may be obtained by moving the lever 24 a corresponding number of times back and forth between its pins, or the pin 37 may be moved out in the slot 36 a distance such as will afford the required extra travel to the lever 24as, for example, to the point marked 36-10 in the drawings-which means that for a tencent cut of cheese from the thirty-six-pound cheese the lever 24 must move from its stop in slot 34 to the stop in slot 36, set at the point in the latter slot marked by the numerals 36-10, and so on for other multiples or values and for the values of other weights of cheese.

In beginning operations with my improved cheese computer and cutter the weight of the cheese is first ascertained and then the pins 35 and 37 are set at the points in said slots which designate the cheese of the ascertained value and weight. After that the operation of the device becomes simply a matter of routine.

Having thus fully described my invention, what I claim as new, and wish to secure by Letters Patent of the United States, is
