It will be realized that whereas I have illustrated and described a practical and operative device that nevertheless many changes may be made Without de arting from the spirit of my invention, an I therefore wish my drawings and description to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my precise showing.
The use and operation of my invention are as follows:
I provide a generally vertical fixed guard 1 plate, arcuately cut away to permit the penetration or the exposure of the rotary knife. The plane of the knife is tilted in order to bring the exposed edge generally into the plane or close to the plane of the forward face of the guard plate, the knife being hollowed or sunk in order to permit its peripheral portion E to extend forwardly beyond the body of the knife. Generally aligned with the fixed guard plate H is the adjustable gauge plate K controlled by the worm J 2 which in turn is controlled by rotation of the handle J The gauge plate and guard plate are slightly bowed to conform'to the curvature of the exposed knife edge. This bowing is particularly important in connection with the gauge plate but is also preferable in connection with the guard plate.
Referring to Figure 3 it will be noted that the upper edge of the guard plate H projects forwardly somewhat as at H in order to permit the central portion, along the arc H to penetrate the space in the knife. It is the central portion which is bowed, in order to conform to the contour of the cutting arc of the knife in the cutting plane. The forwardly offset portion H and a corresponding lower offset portion concealed by the carriage O in Figure 3, are positioned above and below, respectively, that part of the guard plate which normally engages the work as the carriage is reciprocated. I have shown a fixed finger J 5 on the housing opposed to the symbols J t on the handle, but obviously any other practical means for controlling or indicating the necessary rotation of the worm may be employed. In response to rotation of the worm the link or lever K is rotated and moves in unison with the gauge plate K The lever or link rotates necessarily in unison with the link K, the two being of like length between pivot points, the gauge K always lying in a plane parallel with the plane of the guard plate H.
The material being cut is placed upon the carriage and is moved, for the cutting excursion, from left to right, as shown in Figures 2 and 3. The thickness of the slice is determined by the position of the gauge plate, K the slice passes through the aperture between the edge of the knife and the gauge plate K anddrops upon the receiving plate L. from which it may be manually removed. With the gauge plate K supported as herein shown, as the plate is moved 'backwardly from the cutting plane, in order to increase the thickness of the slice to be produced, the arcuate edge of the gauge plate draws readily away from the cutting edge, so that the throat between the gauge plate and the cutting edge is both deepened and widened, and, as the slice is thereby thickened, a relatively greater space is provided, through which the thickened slice may easily pass. This double recessive movement is the necessary result of the employment of the mounting herein shown, but obviously other means may be employed in order to impart to the gauge plate the combined rearward and lateral movement above described. An advantage of this disposition rests in the fact that the thickness of the slice increases more readily than does the actual distance between the gauge plate and the plane of the knife and a smaller'movement of the gauge plate is necessary.
As shown in Figures 2 and 5, the guard plate H is adjustable toward and away from the knife, for example by means of rotation of the threaded stud bolt Q, screwed to the lugs Q, on the frame C and secured by the screws QR threaded into the stud bolt Q. The position of the plate H is preferably initially adj usted at the factory but further adjustment, if necessary, ma easily be made by the operator. The kni e shaft sleeve D being also longitudinally adjusted, it is possible easily. and accurately to position knife and guard plate in the proper relation. The housing C and the plate H between them entirely enclose the knife driving mechanism and the knife is exposed only along the cutting edge and only when the gauge plate is Withdrawn. When the gauge plate is advanced forwardly to the position shown in full line in Figure 2 the entire edge of the knife is guarded or concealed.
