COMPUTING CHEESE-CUTTER.

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed December 15, 1904. Serial No. 236,979.

Figure 1 is a plan view of a cheese com puting or measuring machine, with the cheese-board removed from the table to better show the relation of the parts. Fig. 2 is a plan view, enlarged, showing in detail the locking device for arresting the momentum of the table.- Fig. 3 is a detail section showing the same. Fig. 4 is a detail plan view, enlarged, showing more particularly the clutch carried by the radial actuatingarm. Fig. 5 is a detail section showing the same and taken on the line 5 5 of Fig. 4, and Fig. 6 is a detailplan of the clutch-plate. Fig. 7 is a detail transverse section showing more particularly the vertically-adjustable pin for use as a stop on the price-unit bar.

These improvements have special relation to the invention covered by my former ap-- plications, and particularly application serially numbered 224,576, filed September 15, 1904, and patented August 22, 1905, No. 797,599; and the special object of the present improvements is to insure accuracy of measurement, whether the amount'measured off be a full pound or a fraction thereof, as more fully hereinafter set forth. To the accomplishment of this object and such others as may hereinafter appear the invention consists of the arts and combination of parts hereinafter ully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming part of this specification.

Referring to the drawings by reference characters, a designates the base-ring of the machine, which is adapted at b to receive the standard supporting the knife. (Not shown.)

A bar 0 extends across the base-ring to afford a support for the central pivot of the rotary cheese-table frame d. Opposite the knifereceiving part b the base-ring is provided with a segmental depression or recess, between whose shoulders e e the actuatinglever f is adapted to vibrate in rotating the table. The lever f is pivoted to a lug g on the base-ring adj acent to the knife-receiving part b. The lever actuates the table through the medium of a radial arm h, carrying a clutch at its outer end which engages a depending flange i, carried by the table and a suitable connection between this arm and the lever, this connection being adjustable in order to vary the throw of the radial arm, and thereby vary the amount of cheese measured off by the rotation of the table.

The adjustable connection consists of a sliding box mounted on the arm and having a pivotal connection to a sliding nut is, mounted on the lever below, so that when the nut is slid inward or outward on the lever the box will be similarly adjusted on the arm. The nut 7c is adjusted along the lever by means of a screw-rod Z lying in a channel formed in the lever and extending outward slightly beyond the lever in order that a suitable wrench or key may be applied for turning it. A suitable cheese-total indicator or scale is arranged on the projecting end of the lever, as in my former application hereinbefore mentioned.

The clutch device carried by the arm it consists of a plate m, which is secured to the upper face of the arm by the conjoint action of a pivot-screw n and the table (1. The screw or headed pin a engages loosely a slot or notch 0 formed in the inner end of the plate, and rising from the plate near its outer end is a pair of gripping pins or lugs 0 0, arranged upon opposite sides of and adapted to grip the annular flange i of the table. The inner lug or pin 0 is arranged in advance of the lug 0that is, out of radial alinement with the sameand the two lugs are so spaced with reference to each other that when the arm h is moved in the direction of the arrow shown in Fig. 4 they will grip the flange, and thereby cause the table to move with the arm, and when the arm is moved in the opposite direction the plate carrying the lugs will be swung sufliciently on its pivot to permit the grip-lugs to slide freely on the flange without rotating the table.

It will be observed that the gripping action is caused by the-tendency of the plate m to turn on its pivot n, this tendency to turn on its pivot being caused by the friction of the lu s against the flange.

In order that the lugs shall always grip the flange except when the arm is moving back to its starting position, I provide a spring 2), whose tendency is to swing the plate backward on its pivot, thereby keeping the lugs in close contact with the flange. This causing the lugs to normally grip the flange insures accuracy in the movement of the table, as is obvious.

In Figs. 1 and 2 the actuating-lever is shown in its starting position. When the cheese is Weighed and placed upon the table and the proper adjustment of the connection j k is made through the medium of the screw-rod Z, (this adjustment being indicated by the cheese-total scale on the projecting end of the lever,) the cheese is measured off by vibrating the lever, as is usual in this class of devices. Movement of the lever be tween the stops 0 c after the cheese-total scale is adjusted will measure off exactly one pound of cheese, and fractions of a pound are measured off by a shorter throw of the lever. The forward movement of the lever does not rotate the table, but simply moves the clutch to its starting-point. Then the reverse or backward throw of the lever causes the table to be turned the desired distance whether it be for a full pound or a fraction thereof. It will thus be seen that the actuating-lever is brought back to the same starting-point after each measuring operation-that is to say, the feeding or actuating stroke itself of the lever brings it back to the starting-point, irrespective of the amount of cheese measured 0 Any-suitable devices may be employed for measuring off fractions of a pound. I have shown a series of lugs q q (1 on the base for measuring off, respectively, a quarter, a half, or three-quarters of a pound, these lugs being adapted for use in connection with the spring-retracted stop-pin 1', carried by the lever. Secured to the base and arranged over the lever is a curved bar 3, graduated for use as a price-unit scale, this bar 8 carrying an adjustable slide It, provided with a vertically-adjustable stop-pin u, as in my former application.

i It will be observed that another advantage in actuating the table on the reverse stroke is that the blow of the initial stroke, which is of course the lighter of the two strokes, will be taken up by the stop-pin, while the blow or impact of the actuating stroke will be received by the permanent stop or table-arrester, whereby the stop device will be less liable to injury and disarrangement than if it were arranged so as to take the impact of the working stroke.

For the purpose of arresting the momentum of the table at the end of each working stroke of the lever I provide a simple device which will be caused to grip the depending flange of the table and positively lock the table against further movement when the lever reaches the end of its actuating stroke. Any suitable devices may be employed for this purpose without departing frommy invention. I have shown and I prefer using av finger or arm 1), pivotally mounted by means of a headed screw to on the base adjacent to the stop-shoulder e and extending inwardly under the table. Thisarm v rests upon an inward-extending lug carried by the base, and it is provided with a pair of upwardly-extending grip-lugs or pins 1 1 similar in construction and operation to the grip-lugs 0 0, carried by the clutch. Rising from the lever f in the path of the inner end of the finger o is a lug 2, which carries an ad justable set-screw a, adapted to contact with the adjacent rounded face of the finger when the lever returns to its starting-point, this screw being held in its adjusted position by means of a binding-nut b By means of this screw the device may be adjusted to accurately lock the table at the proper point.

It will be observed that the headed pin or screw to engages loosely a notch in the outer end of the arm 12, so that said arm shall have a pivotal action on said pin or screw sufficient to permit the grip-lugs to bite the flange i when the arm is actuated by contact with the adjusting-screw. The grip-lugs y y are arranged out of radial alinement and the outer lug y is arranged a little forward of the lug y, so that the table will be free to revolve without hindrance from said lugs until the arm v is turned backward on its pivot, as is obvious. The forward movement of arm '0 is limited by stop-pin '0 The advantage in mounting the clutchplate m so that it may have a slight radial movement on the arm in addition to its pivotal movement is that it is thereby free to ad just itself to the clutch rim or flange more ac curately that is, so that both pins may clutch the rim with equal force even after the pins become worn.

It will be observed that an important advantage is derived by pivoting the operatinglever at a point considerably beyond the center of the table from the side at which the handle end of the lever projects. This arrangement gives an augmented throw of the handle ortion or that portion which works along t e scale-plate-that is, for a given movement of the table the projecting portion of the lever will move farther and faster than the periphery of the table. This enables me to use a scale having larger graduations-i. a, graduations set farther apart than would be the case were the lever pivoted at or near the center of the table so as to rotate in unison with it. Where the lever is pivoted at or near the center, it necessarily travels the same distance as the table to measure off a given quantity of cheese, so that particularly when a heavy cheese is being measured off and a fraction of a pound only is desired the movement of the table will be necessarily comparatively slight, as the slice must be cut comparatively thin. This, as is obvious, will require to attain the necessary accuracy that avery fine scale be used and that all lost motion will be eliminated and that the clutch shall operate with a great degree of accuracy; but by giving the lever or that part of it which works in conjunction with the scale an augmented throw a much greater degree of accuracy is obtainable with a given degree of skill and care in the construction of the table-operating devices.

It will be apparent to those skilled in the art that various mechanical embodiments of the invention are possible, and I therefore do not wish to be limited to the exact arrangement and construction shown.
