I 'lkpplication filed. January 8, 1903. Serial No. 138,210.

To all whom it may concern:

Be it known that I, EDWARD F. SMITH, of

Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Slicing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention has for its object to provide a machine for slicing meat, bread and similar material and it embodies generally a support or holder and a reciprocatory carriage having mounted thereon a continuously operated rotary cutter and means for operating it and reciprocating the carriage whereby a draw out is effected.

My invention also has for its object to provide means for adjusting the movement of the carriage relatively to the movement of the cutting portion of the knife whereby a greater or lesser portion of the blade may be moved in contact with the material, depending upon the nature thereof and to these and other ends my invention consists in certain improvements and combinations of parts all as will be fully described and the novel features pointed outin the claims at the end of the specification.

In the drawings: Figure 1 is a top plan view of a slicing machine constructed in accordance with my invention. Fig. 2 is an end elevation thereof showing the parts at the beginning of the slicing operation. Fig. 3 is a similar view showing the parts at the completion of said operation. Fig. 4 is a rear elevation shown partly in section. Fig. 5 is a horizontal sectional view taken on the line AA of Fi 2. Fi 6 is a vertical sectional view t rough the cutting knife taken on the line C-O of Fig. 2. Fig. 7 is a detail sectional view on the line DD of Fig. 2 showing the sharpening device. Fig. 8 is a detail sectional view on the line E-E of Fig. 2.

Similar reference numerals in the several figures indicate similar parts.

A slicing machine constructed in accordance with my invention embodies a-supporting frame or holder a which may be conveniently mounted u on a table or other support or mounted as s own, upon suitable downwardly extending legs I). At one side 1 of the frame isprovided a trough or receptacle, adapted to contain the material to be sliced, which is formed by vertically extending sides '0. The material to be operated upon, such as bread or meat is conveniently operated toward the cutting knife by hand although it will be understood any suitable means may be employed for this purpose and in order to hold it firmly during the slicing operation I form the bottom of the trough at a slight angle to a horizontal plane, at its outer or forward end, as shown particularly in Fig. 4 so that the material supported thereon will be naturally crowded against the outer wall 0 of the trough. To this end I also arrange a movable guard frame provided with the top and side adapted to engage the corresponding portions of the material and which are movable relatively to both the bottom and side of the trough. This frame or presser may be formed in a variety of ways but the construction which I deem preferable is that, shown in Figs. 1 and 4, in which it is provided with its up or and lower ends 20 and 21 respectively gui ed in apertures formed in the holder at and wall 0 and having at its side an outwardly and upwardly extending arm or guide '5 provided with a slot through which extends a pin upon a suitable bracket whereby the frame may be adjusted relatively to the side and bottom of the holder to accommodate both small and large pieces of material.

At the center or angle portion of the guard frame is provided the flange 22 flaring outwardly, in the direction from which the material is advanced, so that as irregularities of the material engage therewith the guard will be raised and lowered and the frame held in .contact with the material at all times preventing the operators fingers from accidental contact with the cutting knife. If the operator desires he may conveniently remove the frame by tilting it to the position shown in dotted lines in Fig. 4.

At the forward end of the support or holder a is a vertically extending supplemental frame 7c, provided at its upper and lower sides with ways Z, upon which is movably mounted a reciprocatory and transversely movable carriage m movably secured to the frame it by means of clamping pieces a adapted to engage over the guides, as shown in Figs. 4 and 6. Arranged on the carriage is a relatively stationary stop plate 0 adapted to be engaged by the material to be sliced and, pivotally mountedin rear of said stop plate is a rotary cutting knife'p, having the over hanging cutting portion or edge (1 arranged in the plane of the stop plate, as shown in Figs. 5 and 7, and as a convenient means of construction I mount the cutter upon a stud 11 attached to the plate. The rotary and re ciprocatory motion of the cutter and carriage respectively is accomplished by a single 0 erating means as'will be further described. 'I 1e "rotary motion'of the cutter is imparted to. it by; means of; a small pinion s rigidly se'cured' thereto and meshing with the teeth of; an internal gear formed. on the plate or disk t; pivotally journaled upon a studu secured to an arm 12 on the reciprocatory carrFiagee tending in rear of the stop plate, (see w indicates an arm attached to the carriage andto the stop plateo tostrengthen the latter, saidarm being off set as willbe understoodto accommodate the overhanging edge of;.the knife or cutter.

' The disk t constituting a driving wheel, is adapted to be rotatedxby a handle a: which is attachedto a wrist pin y, and also j ournaled on'the latter is a radius. arm or link 2, the outer endof which is pivotally attached to a lug or extension 10 on the frame is so that. as the drivingwheel'isv operatedby the movement of..the handle, a reciprocatory motion will be imparted to the carriage. In order that the distance through which the carriage is m'oved,'at each revolution of the crank handle. may be adjusted to accommodate it to the nature ofthe material to be operated upon, I provide 'means for" adjusting the wrist pin 'y relatively to the journal a of the driving wheel. have shown the Wrist: pin arrangedupon a plate 2fwhich is secured. to the'diskt by means of screws. or bolts 3 which latter may bei'readily removed and inserted in other threadedrapertures (as shownin dotted lines in" Fig. 3).to increase the diameter of the circle described by the rotation of the pin thereby causing the carriage to be operated through greater or less distance as may be required by the nature of the material-operatedupon.

For instance in operating upon a small piece ofirelatively hard material the Wrist pin is arranged near the center of rotation and the rotary-movement of .the cutting'edge willbe the same while the amount, of reciprocation of. the carriage willjb'e shorter.

Arranged at the forward endof the carriage m is a gage plate 4 which is adapted to be normally in line with the forwardor open endof the trough andin order that the thickness ofthe slices of materialto be removed,

may-be varied, I provide said gage plate with a ing threadedlugs or ears 7 engagedby an In the present; instance 1' adjusting screw 8, by means of which the gage plate may be moved relatively to the plane of the'l'rnife or cutter.

As a convenient means for sharpening the rotary knife g I have provided at the upper side of the frame m ears or lugs between which are pivoted arms 11 carrying at their outerends a piece of abrasive material, indicated by 12, which is adapted to engage the edge of the knife, as shown in full lines in Figs. 2 and 7. The arms 11 are attached to a hub, as shown, having flattened or angular surfaces 13 and 1 1 against which engages a spring-operated finger 50, said surfaces being so arranged that when the block is. moved into the operative position it will be held yieldingly in contact with the edge of the knife, during the rotation of..the latter, andwhen the finger 50. is in engagement with the face 1.4. the device will be s'upportedin the opera tive position, as shown in dotted lines in Fig. 7;. 'ihegrinding device being mounted-upon the carriage it: may be moved into contact therewith and employedto sharpen the knife during a slicing operation.

The'operation of the machine will now be understood. The material to be out, such as shown in fulllines in Fig. 1 and in dotted lines in Fig. 5, is placed in the trough or holder between the side plates 0 and it is moved into engagement. with the gage plate twhich may be adj'ustedto determine the thickness of the slice. The operator revolving the handle '96 moves the carriage m from the position shown in Figs. 1. and, 2to that. shown in Fig. 3. This occurs simultaneously with the rotation of the knife, through the operation ofthe pinion s and the contact therewith theslice is all'owedto fall .away from the machine into any suitable receptacle. The continued rotation of'the .handle causes the carriage to be retracted .allowmg the material to be again moved into contact with the gage plate and an additionalslice to be cut therefrom.
