CHEESE-CUTTING MACHINE.

Specification of Letters Patent.

Application filed May 5,1905. Serial No. 259,042.

with a rotatable cheese-carrier; and the objects of my invention are to devise a cheap and simply-constructed. machine of this class in which the raising of the handle, in addition to the moving of the cheese-carrier, will operate an index-finger over an indicator-dial in such a manner as to indicate the weight of cheese which would be cut at any point were the knife there lowered; andit consists, es-

sentially, of a revolubly-supported 'cuttingknife, a lever integral with the supportingtrunnions, an index-finger on one endofthe said lever adapted to coact with the indicator-card provided on the frame, an adjustable tappet secured on the other end of the lever and a graduatedlscale provided on said lever to correspond to the total weights of the cheese, an index-mark on said tap et to coact with said graduatiomscale, a c eesecarrier, means for communicating the motion of the tappet to the said carrier, and means for preventing the rotation of said carrier except in one direction, the various parts ofthe device being constructed and arrangedin detailas hereinafter more particularly described.

and rotate the carrier. Fig. 7 is an enlarged detail showing a horizontal section of the construction shown in Fig. 5.

In the drawings like letters of reference indicate corresponding parts ineach figure.

A is thebase of the cutter, which may be of anydesirable form, preferably as shown.

Standards a a upwardly extend from two portions of the circumference thereof.

B is the cutting-knife,secured in the frame I), provided with trunnions b and N, which are journaled in bearings a anda, provided on the standards a and (1 A handle 12 is also provided at one end. thereof for convenience'in operation.

C is a lever made integral with an extension of the trunnion 5 provided at one'end with an index-pointer 0, adapted to coact with an indicator-card g, contained on a frame G, supported by standards 9.

c is a tappet slidably secured on the lever C, of any desirable form, but preferably substantially as shown, which consists of a frame 0 adapted to fit around three sides of the leverC, a thumb-screw c to lock it at' any desirable point thereon, and'an antifrictiOnrollercfi revolubly supportedon a shaft integral with the said frame 0 The edges 0 of the lever C are preferably beveled, as shown, whereby the tappet may be more readily secured thereon. Graduations c to correspond with the total'weight ofthe cheese on the carrier are provided on the face of the lever C, and an index-mark c is provided on the tappet adapted to coact with such graduations.

E is a spider integral with the hase A and provided with an upwardly-extending pintle e.

D is a lever or frame rotatably supported by the pintle e and provided at one end thereof with an upwardly-extending standard (1 and near the end thereof with a plurality of pawls d pivoted in the casing cl and resiliently held against the cheese-carrier by means of the springs (P, as shown in detail in In this manner when the lever D is rotated in one direction the cheese-carrier will be forced to rotate with it, but will not rotate with it in the other direction. An extension d is provided at the opposite end of the said lever D, and a spring (1 connects f at the extremities thereof, which are adapted to engage a track provided in the cheese carrier and so steady and hold it in position. At the end of one of these arms a plurality of ratchet-teethf pivoted in a frame f, are resiliently held in contact with the cheese-carrier H by means of springs f, as shown in Figs. 5 and 7. It will thus be seen that these ratchet-teeth will only permit of rotation of the carrier H in one direction.

Having now pointed out the various elements in the mechanism, I will briefly describe the method of operation of the same.

The indicator-card G has a plurality of columns 9 in which the prices of the cheese are placed in such a manner as to indicate by reference to the column 9 giving the Weights of the cheese, the price that should be charged for the amount cut. In operating the device the first thin to do is to place the tappet c on the lever 6 so that the index-mark a will be opposite the graduation on the scale 0 corresponding to the weight of the cheese which is on the cutter. The handle is then raised. During the first portion of the stroke the cheese-carrier is not rotated; but as soon as the tappet 0 comes in contact with the standard d the lever D is rotated, carrying with it the cheese-carrier H. At the same ime as the tappet 0 comes in contact with the standard at the index-finger 0 comes into position at the bottom of the indicator-card g. The motion being continued, the carrier will be rotated and the index-finger will simultaneously move farther on the indicator card g. To ascertain the price of the cheese to be out, were the knife to be lowered at any point, reference is made to the indicator-card g. For instance, supposing the index-finger 0 had moved up to the position in the column 9 and that the index on the tappet had been set at the graduation corresponding to a ten-pound cheese, reference to the card would show in the column of the indicator-card corresponding to ten cents, or whatever might be the price of the cheese per pound, and opposite the figure 1}, at which the index-finger stood, would be found the price, in this case five cents. When the knife is lowered, the tappet c is brought out of contact with the standard d, and the spring (i acting on the extension (1 returns the frame D to its normal position abutting the standard. The spring-held pawlsf prevent the carrier H moving with the frame. It will thus be seen that each time the handle is raised and lowered the cheese is advanced a certain distance and at the end of the operation is left'with the segment which has been cut off on one side of the cutting-knife and the remainder of the cheese on the other.

By means of the tappet c the cutter may be used on any weight of cheese, all the change necessary to make for the various weights being to move the tappet c.

The chief advantage of my device is that it enables the fraction of pounds of the cheese to be accurately measured, whichhas hitherto not been possible in other forms of cheesecutters. It is evident that any fraction whatever of a cheese could be cut on my cutter.

It is to be understood that in carrying out my device various changes may be made in the details of construction without departing from the spirit of my invention.

What I claim as my invention is 1. In a cheese-cutter, the combination with the cheese-carrier, of a pivotally-supported knife, an arm connected with the knife so as to move therewith, and a tappet -roller adjustably carried by the arm, and means operated by said tappet-roller serving to rotate the carrier, substantially as described.
