JOHN HALLIDAY, OF DETROIT, MICHIGAN.

CHEESE-CUTTER.

Specification of Letters Patent.

Patented May 8, 1906.

Application filed November 21. 1903. Serial No. 182,161.

To aZZ whom it may concern:

Be it known that I, JOHN HALLIDAY, a subject of the King of Great Britain, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Cheese-Cutters; and I 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 pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Myinvention relates to cheese-cutters; and it consists in the improvements hereinafter described, and'pointed' out in the claims.

Referring to the accompanying drawings, Figure 1 is an elevation of a cheese-cutter with the knife broken away embodying my inven tion. Fig. 2 is a plan view of the same. Fi 3 is a section on the line 3 3 of Fig. 2, the knife being shown in full. Fig. 4 is a detail elevation of a portion of the cheese-cutter, showing the knife in its closed position. Fig. 5 is a detail plan of the operating-lever, the dogs of the pawl being removed. Fig. 6 is a detail of the handle by which the knife is operated. Fig. 7 is a plan view of the slide which cooperates with the operating-lever to adjust the throw of the same.

A is the annular base having an outward radial projection A and an inner radial projection A, in which is a radially-extending dovetailed groove A A is a segmental strip of metal secured to the opposite edge of the base A and having a scale on its upper surface designed to correspond to the weight of the cheese that is be g cut.

A A A are radial spokes extending inward from the annular base A and supporting at their centers a bearing A", in which is secured the vertical pivotal pin 13*.

B is a ring provided with a cross-piece B and pivoted upon the pin B at B A A designate lugs adapted to center the ring B. The ring B is provided around its periphery with ratchet-teeth B.

B is a pawl-case secured to the base A and provided with a number of dogs adapted to engage the ratchet-teeth B. The dogs of the pawl-case B are so spaced that their distance apart is not an exact multiple of the length of one of the teeth B. Thus one of the pawls will engage said teeth with a less the teeth B.

C is a circular wooden disk centered upon the pivotal pin B and resting upon the ring B. The disk C forms a table upon which the cheese is placed to be out.

A represents arms extending outward from the base A. A knife A A is pivoted between the outer ends of the arms A and swings inward and downward upon the disk 0, as indicated in Fi 4.

A is an adjustabIe handle upon the frame of the knife A A A is a radially-extend ing slotted link pivoted to the base A and having a pin upon the knife A A, engaging in its slot and serving to limit the outward motion of the knife A A.

D is adovetailed plate fitting in the dove tailed slot A and adapted to reciprocate therein radially to the base A.

D is a segmental guide on the outer end of movement of the ring B than the length of the plate D, having pins or stops D at its ends to limit the motion of the operating-lever. The upper plate of the segmental guide D is graduated on its upper surfaces to indicate fourths of the travel of the operating-lever.

D D D are grooves in the upper surfaces of the plate D. g

D is a lever-arm pivoted upon the pin B and having its outer end provided with a handle and swinging over the scale upon the segmental strip A 61 is a thumb-screw for fixing the leverarm D in any desired position.

D is a connecting-link pivoted to the arm D and to the plate D.

It will be seen that by turning the leverarm D the plate D is adjusted radially to the base A.

E is the operating-lever pivoted at its inner end upon the pin B extending over the plate D and through the guide D and provided with a handle E at its outer end.

F is a awl-case upon the o erating-lever E, provi ed with dogs adapte to engage the ratchet-teeth B to turn the ring B, and conindicating the weight of the cheese.

base A the greater will be the throw of the operating-lever E, and the closer said guide is to the center of said base the less will be the throw of said lever.

The grooves D D D are cut so that the center is radial and marks the mid-position or half-way position of the operating-lever.

The outside grooves are diverging and mark the quarter and three-quarter position of the operating-lever in every position of the plate D, the pin E engaging in these grooves to denote when the corresponding position is reached.

The operation of the above-described de-. vice is as follows: The cheese is first weighed and then placed upon the disk C concentric therewith. The lever-arm D1 is then moved along the scale A to the figure of said S IC iLIlG 1s moves the plate D, and consequently the stops D D to such a position that the throw of the operating-lever E when it contacts said stops is sufficient to turn the disk 0 a distance so that the knife A A moving in an invariable plane shall cut off one pound of cheese. If it is desired to cut off a half a pound, the operating-lever E is moved until the pin E engages the middle groove D If one-quarter or threequarters of a pound is to be cut, the operating-lever E is moved from said stop until the pin E engages the corresponding outer groove D a a are set-screws by which any lost motion between the plate D and the groove in which it reciprocates may be taken up.

It will be evident that various mechanical changes may be made without departing from my invention.

- What I claim is- 1. In a cheese-cutter, the combination of a support for the cheese, a knife adapted to move in a plane radial to the cheese when on said support, an oscillating part adapted to change the relative angular position of said knife and support in proportion to the extent of its travel, a stop to limit the motion of said oscillating part, a scale and alever-arm adapted to move over said scale and to adjust the position of said stop.
