8 Claims,

This invention relates to slicing machines and particularly to a slicing machine having a rotary slicing knife, and a gauge plate for determining the thickness of slices of substance-to be cut, which is adjustable simultaneously both obliquely and perpendicularly in relation to the cutting plane of the slicing knife.

An object of this invention is to provide a slicing machine in which a gauge plate is mounted on a slide member for movement to various positions of adjustment in planes parallel to the cutting plane of the slicing knife, and the slide member is arranged for movement in an angular direction in relation to the cutting plane of the slicing knife.

Another object of the invention is to provide a slicing machine employing a rotary slicing knife and an adjustable gauge plate in which the gauge plate is adjustable to a position in the cutting plane of the knife and planes parallel thereto, and the application of power to the slicing knife and the adjustment of the gauge plate are controlled by a common control member, and the operation of the control of the application of power to theknife is possible only when the gauge plate is positioned in alignment with the cutting plane of the knife.

A further object of the invention is to provide means in a slicing machine having an adjustable gauge plate and a rotary slicing knife, for indicating the thickness of a slice to be cut according to the position of adjustment of the gauge plate and the kind of substance to be sliced.

This invention further resides in the combination, construction and arrangement of .parts illustrated in the accompanying drawings, and while there is shown therein preferred embodiments of the invention, it is to be understood that the same are susceptible of modification and change without departing from the spirit of the invention.

The accompanying drawings illustrate a se lected embodiment of the invention, and the views therein are as follows:

Fig. 1 is a plan view of a machine embodying the invention; 7

Fig. 2 is a partial vertical section alone the line 22 of Fi 1;

Fig. 3 is a partial vertical section along the line 3-3 of.Fig. 1;

Fig. 4 is a partial vertical section along the line 44 of Fig. 2; and

Fig. 5 is a detail perspective view of certain parts of the machine shown in Fig. 2.

The particular embodiment of the invention illustrated in the drawings and generally designated by the numeral 6 comprises a base I, a motor 8 mounted on the base and operatively I connected with a shaft 9, rotatably mounted in a support 10 secured on the base I. A gauge plate II is slidably mounted on the base I in adjustable spaced relation with a rotary slicing knife l2 which is fixedly mounted on the shaft 9.

' The gauge plate I I is fixedly mounted on one end of a carriage or slide member Hi. The slide member I3 is in the form of a parallelogram .and of dovetail cross-sectional configuration; and is arranged between opposed, parallel guides l4 and I5 for sliding obliquely on the top l6 of the base I. To this end the guides l4 and I5 are secured to the top Hi by means of screws 11 and disposed angularly in relation to the top so as to conform with the adjacent sides of the member IS.

The member l3 and the gauge plate H are movable in relation to the base landthe knife.

l2 by means of a manually-operable knob l8 which is fixedly mounted upon one end of a shaft l9. The opposite end of the shaft I9 is adapted to be received in a bore at one end of a generally tubular member 20 in releasable interlocking engagement therewith, a pin 2| being provided on the shaft l9 and adapted to be re' ceived in a slot 22 in the member 20 for this purpose. The opposite end of the member 20 is providedwith a journal portion 20-a. The

journal 2ll-a and the portion of the shaft l9 adjacent the knob l8 are mounted in bearings 23 and 24, respectively, provided interiorly of the base I; the bearing 23 being mounted on theunderside of the top l6 and the bearing 24 being mounted in the bore of a boss 24b provided in a side wall of the base and secured therein by means of a set screw 24-11, 1

The member 20 has an externally toothed por-' tion 20-1) the teeth 2llc of which are elongated for a purpose hereinafter to be mentioned, and arranged to mesh with the teeth 25-11 of a rack 25 which is secured by means of setscrews 26 to the underside of the slide member !3. The top It is slotted as indicated at lB-a in Fig. 2

to provide for travel of the rack 25. The rack 25 is arranged perpendicularly in relation to the gauge plate H. The'arrangement is such that upon the shaft [9 being interlocked with the. member 20 and the knob 18 being rotated, the

member l3 and the gauge plate will be moved in relation to the base 1 and the knife l2 according to the direction of rotation of the knob l8. As the member 13 is disposed obliquely with respect to the top l6 and the gauge plate H, and

the rack 25 is arranged perpendicularly in relation to the gauge plate II, the rack 25 will travel longitudinally in relation to the axis of the shaft I9 upon rotation of the shaft, making necessary the provision of elongated teeth on the member 20.

It will be readily understood that upon adjustment of the'position of the gauge plate II by turning the knob I8, the shaft I9 being in looking engagement with the member 28, the gauge plate will be displaced in relation to the cutting plane of the knife I2 in two directions, that is, perpendicularly to the cuttingplane of the knife and obliquely thereto, as illustrated in dotted lines in Fig. 1. r I

It is desirable in a slicing machine of the kind described to have a. convenient indication of the position of the gauge plate in relation to the cutting plane of the knife and the corresponding thickness of substance to be cut, especially with reference to particularsubstance. In order to provide such an indication the present invention includes an indicating device which upon the upper front portion of the base of the machine. This indicating'device is operatively connected with the means for adjusting the position of the gauge plate by means which includes rack teeth 21 which are provided on the front edge of the member I3 for meshing with a gear segment 28 which is rotatably mounted on a stub shaft 29 and p The stub shaft 29 may be in the form of a screw arranged in a conveniently disposed threaded opening in the top I6. A cutaway portion I 4-a is provided in the guide I4 for receiving the gear segment 28. The pointer 38 is preferably arranged in association with a graduated translucent scale or dial plate 3I. Theplate 3I may be secured, as by means of screws 32, upon a cover 33, which preferably extends over the entire top I6. The dial plate 3 I may be provided with graduations to show the thickness of the slice to be cut and suggested thicknesses of slices forvarious substances. An electric light (not shown) may be provided to illuminate the indicating device and reflect the thickness of slice to be cut by projecting the shadow of the pointer'upon the translucent dial plate. r

In addition to regulating the thickness of slices the knob I8 may be utilized to control the application of power to the knife I2. This may be accomplished by means of a sleeve 34 secured on the shaft I9 intermediately of the member and the bearing 24, as by means ofa set screw 34-b. The sleeve 34 is provided with an annular groove 34-11 adapted to receive one end of a crank 35. The crank 35 is pivotally mounted at 35-a upon a bracket 36 supported on the base I and has itsopposite end operatively connected with an electric switch 31, which is operatively connected with the motor 8. The arrangement of these parts is such that upon movement of the shaft I9 a predetermined distance longitudinally in relation to its axis, the crank 35 will operate to throw the switch 31 from off position to on position and vice-versa according'to the direction of movement ofthe shaft I9.

In order that the cutting edge of the slicing knife be guarded toavoid accidental cutting of the hands of the operator when the machine is being loaded, unloaded or cleaned, and the knife is not being operated, the switch control mechanism is arranged so that the switch maybe thrown to foif position only when the gauge carries a pointer 30.

plate is atzero position that is, in substantial is mounted top of the position of the alignment with the knife. For this purpose the shaft I9 is provided with a second pin 38 which is arranged in spaced relation with the pin 2I and so as to abut the inner end of the bearing 24 when the pin 2I is within the slot 22 (see Fig. 2) and to be received in a slot 39 extending longitudinally of the bearing 24 from its inner end upon outward movement of the shaft. The pin 38 and slot 39 are so disposed that the slot 39 will be in position to receive the pin 38 only when the gauge plate is in zero position as above stated.

A coil spring 40 is arranged Within the hollow portion of the member 28 intermediate the inner end of the shaft I9 and the journaled end of the member 28-so as to operate to move the shaft I9 outwardly when the pin 38 is in position to be received in the slot 39. The length of the slots 22 and 39, the position of the sleeve 34 on the shaft I9, and the throw of the switch 3'! are so correlated that when the shaft is moved outwardly by operation of the spring 40 the pin 2| will be withdrawn from the slot 22, the pin 38 will be received in the slot 39, and the switch 31 will be thrown from on to ofi" position. The shaft I9 and the switch 31 will thereafter remain locked in their respective positions until upon inward movement of the shaft I9, as by pressing the knob I8, the pin 38 is withdrawn from the slot 39 and the switch 31 thrown to on position, when the knob I8 may be rotated to adjust the gauge plate and lock, the switch in on position.
