COMPUTING CHEESE-CUTTER.

VApplication iiled October, 1904. Serial No. 227,181. l

' the cheese-carrying table-may be moved very accurately in order thata cheese placed thereon may be firmly and accurately subdivided, and to this end includes'a peculiar single-acting driving connection which will not tend to move the table backward on the return stroke of' the operating-lever.

A further object of my invention is to so arrange the parts that without sacrificing accuracy of movement-the operating parts may not project above the level of the table, but may instead be down out of the way, yet so arranged that only a low base is required and also so that a considerable movement of the operating-lever may be required for a comparatively small movement of the cheese-carrying table.

A further objectof my invention is to provide means for holding a multiplicity of measuring cards or charts for use in connection with cheeses of different weights and values and to provide such improvements in details of construction as shall be hereinafter pointed VAout.

' The accompanying drawings illustrate my invention. f

Figure 1 is a perspective view of a cheesecutter embodying my improvements; Fig. 2, a plan, about-full size, of the operating elements for rotating the cheese-carrying table; Fig. 3, an under plan of the same parts; Fig. 4, a section on line 4 4 of Fig. 2; and Fig. 5 is a vertical section, on a smaller scale, through the base and table. l

In the drawings, 10 indicates a base-casting provided at its center with a vertical pin 11, adapted to enter the central bearing 12 of the horizontally-rotating table 13. Table 13. is provided on its upper face with a plurality of retaining-prongs 14, upon which the cheese may be placed. On its lower face table 13 carries a gear 15, which is adapted to mesh with a pinion 16. Pinion 16 is journaled upon a vertical stationary pin 17, secured in the base-frame 10, and is provided on its lower side with a hub 16', having a smooth periphery. Journaled upon the hub 16' is a yoke 18,

in which is pivotedan operating-lever 19. The

Aoperating-lever 19 is'provided with a camshaped innery end 19', adapted to engage the periphery ofthe hub 16', and the operatinglever is normally urged forward by means of a light'spring 20, thus normally holding the cam end 19'in-engagement with the periphery pin 17, above pinion 16, is a sleeve 21, provided upon one side with a key 22, which is parallel with the axis of the sleeveand so arranged thatits lower end may project into an opening 23, formed in the upper face of the pinion 16, the arrangement being such that the sleeve 21 will rotate with the pinion 16,but may be easily removed therefrom. Slipped over the sleeve 21 are several charts or disks 24, which are keyed to the sleeve 21, so as to rotate therevwith,'by means of the key 22. Each chart or disk is provided upon at `least one facewith a series of division-marks 24'., equally angularly spaced, and each of said disks is then marked to indicate the total price of the cheese to be cut and the number of cuts to be made in such cheeseas, 'for instance, if a cheese'having a total value of three dollars is to'be retailed in slices the minimum value of which shall be five cents one of the charts 24 ,ing such arrangement that'a movement ofthe pinion vv16 through a distance equal to one of subdivisions will cause the cheese-table 13 to move through six degrees, thus requiring sixty steps of the cheese-table to make a complete revolution, and thus providing means bywhich the cheese may beaccurately cut into sixty equal slices the value of each of which shall be live cents and the total value of which shall be three dollars.

The pinion 16 is inclosed by a partial annulus 10', which is preferably integral with the main 'base v10 and a piece of clear celluloid or glass or other transparent body 25 slipped over sleeve 21 on top of the stack of `disks 24.v The upper end of sleeve 21 pro- 21, and secured to this upper end is a hand or pointer 27, whichremains xed during op- Journaled upon the upper end of forward across the table 13 and carries at its inner or rear end a knife 34, the forward lower corner of which when the knife is in the position shown in Fig. 1 reaches approximately to the center of table 13.

In operation the cheese is placed upon the table 13, the knife 34 being thrown back out of the way. If `the total value of the cheese is, say, three dollars, the operator will remove

hands

26 and 27 and cover 25 and then select the desired disk 24 which will be so subdivided as to indicate sixty steps of thetable 13 to complete a revolution. If desired, the entire stack, together with the sleeve 21, may be removed to facilitate the selection of the desired disk 24.

The parts will then be returned to position, the selected disk 24 being on top. The operator then grasps the lever 19 and moves it in the direction indicated by the arrow in Fig. 2, thus drawing the cam-shaped end thereof against the hub 16 and rotating the pinion 16 in one direction, so as to cause the table 13 to rotate, this movement continuing until the hand 26 has been moved from the hand 27 an angular distance as indicated by the divisions on the visible disk 24 equal to the amount of cheese desired, whereupon the cutter will be operated and a wedge of cheese cut from the main body-as, for instance, if a wedge of cheese having a value of twenty cents is desired the hand 26 will be moved from the hand 27 an angular distance equal to four subdivisions of the visible disk 24. The operator will then return the hand 26 to a point immediately beneath the hand 27, the sleeve 21 and all of the parts, including the cheese-table and the operating-lever 19, remainining stationary while this is being done. When another wedge of cheese is to be cut, the operation is repeated by first swinging lever 19 backward to obtain a new hold upon hub 16 and then forward in the manner already described. The backward movement of lever 19 swings the end 19 away from the hub 16', so that there is no tendency to move the table 13' backward. By the use of the cam-shaped end of the operating-lever and the smooth periphery of the hub 16 an engagement between the two may be had at any point, thus increasing the accuracy of the operation.
