To all whom it may concern Be it known that I, RAYMOND ST. CLAIR Fow, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inment of. the slicingknife very regular andpowerful and thecarriage-movement very steady through the construction and mutual relations of the fly wheel, the apparatus for moving the carriage, and the knife revolving mechanism are features of mv invention. Other features will appear from the detailed description.

Figure 1 is a side elevation of my invent ed device. Fig. 2 is aplan view of the carriage; Fig. 3 is a rear end elevation; Fig. 4

is a section on line XX on Fig. 1. Fig. 5

is a section on line Y-Y of Fig. 4. Fig. 6 is a rear end elevation of a portion of the carriage showing the feed regulating mechanism. Fig. 7 a is a front end elevation of part of the carriage showing the spacing mechanism. Fig. 8 shows the knife and its movable gu'ard looki toward the same from the front end of t e machine;

The knife 72, the fly wheel 24 and the carriage' 43 are operated from the "shaft 31. This shaft is turned by thecrank 601 and handle 610. The bevel wheel 29 turns the fly wheel 24 by the bevel wheel 25, and the bevel wheel 30 engaging with the bevel wheel 28, turns, through the shaft 32, the

arm 13, that-engages in the cam slot 20 in the cam 14 secured to the carriage 43. The

"shaft30 also carries the bevel wheel 98, that engages with the bevel wheel 96. on the shaft bythe chain 64 turns the sprocket wheelv 63 which turns the shaft on which is mounted the knife 72. This construction gives a very rapid rotation to the fly wheel and to the knife. The momentum of the former of the latter from being interrupted by an occasional hardness of the material to be cut, and the great rapidityof the movement of the knife will enable it to out through bone or other hard material with ease.

The carriage 43 runs on tracks attached to the framework 110 of the machine. To give the greatest ease to its movement, these tracks should be round rods 11 engaged by lugs 12 on the carriage, projecting below its bed, and fitting the rods. The carriage reclprocating mechanism is cam 14 in which is the cam slot 20, is secured to the carriage 43. The pin 15 in the rotatlng arm 13, engages in the slot 20, and the slot and the arm are so arran ed that when the carriage 43 is nearing the end of its movement, the movement of the pin will gradually have become one along the slot 20 with a very slight moving of the carriage,

and at the extremity of the carriages move ment, the angular movement of arm 13 will produce, for a moment, a motion of the pin along the slot 20 without producing any forward or backward movement of the carriage 43. The -cam. slot can be arranged relatively to the axis of rotation of arm 13, and shaped so that the reciprocating movement of the carriage can be hastened or retarded during portions of the reciprocating movement.

The cam slot, as illustrated, will cause the ra id withdrawal of the carriage immediately after the cut of the knife is concluded, and will slow up the carriage while the feed regulating mechanism is being operated; this motion is produced by the forwardly bent part 210,- of the cam slot 20.

.- The platform 42 rests on. the carriage 43, and moves freely thereon, and can be lifted freely-from it. The feed regulating mechanism is as follows: The carriage is provided with the shaft 4 and the worm 1, which engages with the thread 49 of the rack 4' depending from the platform 42, and is rotated by the pawl and ratchet operated gear wheel mechanism which latter is operated by a trip '8, which last is operated by an ad justable stop mechanism. These mechanisms are preferably as follows: The gear wheel 5 is placed on the end of the shaft 4. It meshes with gear wheel 6 concentric'with which is .the ratchet wheel 7 The trip 8 is mounted concentrically with these wheels and carries the pawl-9. The trip 8'is bent forward at its lower end. The adjustable stop 3 .is mounted on the lever 8-7 fulcrumed on pinas follows. I The 88, on the frame 110 ofthe machine, and is lifted and lowered by moving the head 82 along the scale 81. This head is connected to the lever 87 by the bell crank arm 80. The gear wheels are mounted on the ledge 411 attached to carriage 43 and projecting over frame 110. The trip 5 contacting with the, stop 3, in the course of the backward movement of the carriage, causes the last named mechanisms to operate the feed regulating mechanisms.

The material to be spliced is held on the platform 42 by a yielding holder consisting of arms40 secured rigidly to each other and having branches 45 provided with spurs.- These arms are ivotally attached to standards 46 on the p atform 42 by the spindle 41 and are yieldingly actuated toward the platform by the springs 74. These springs are attached to the arms 40 and to the block 7 9 on the spindle 41. The block 79can be secured after it has been turned in any position to give any desired tension to spring 74. 78 is a key to turn the spindle 41. The roller 55 is mounted between the arms of the standard 56. It can be set by the set screw 57, turning in the lug 58 against the arm 59 that, when not held by screw 57 is movable in a hole in lug 58.

The holder, the platform, and the material held thereon form a separable portion of the machine freely removable from the carriage, and duplicates of this separable portion may be provided. The fly wheel 24 rests upon roller bearings 26, and is geared to rotate much more rapidly than the arm 13. It revolves on the spindle 32, which turns the arm 13 carrying. the pin 15. This spindle also revolves in the same direction as the fly wheel 24, but more slowly. This construction minimizes the friction of the fly wheel. The fly wheel has a very heavy rim and preferably is cast in one piece with the bevel wheel 25. It is contained with very little waste space in the frame 110 that protects the garments of the operator from it. v

The rind slicing device is a rotating knife 17 and mechanism for rotating it from the reciprocating movement of the carriage consisting of a spindle 19 on which is placed a gear wheel 18, which is adapted to mesh with the rack 180 placed upon the carriage, when the rod 16, upon which the spindle 19 is angularly mounted, is turned. This rod is supported by hangers 36, and may be 'turned by a head 190. The edge of the 'knife turns more rapidly than the carriage moves thus securing a very clean cut of the rind, and hence permitting it to be out very thin and with trifling waste.

The guard of the knife has a permanent and a movable part. The permanent part protects the user of the machine against the part of the knife lying on the opposite ble link 67, which has a center of rota- 7 tion concentric with the shaft 60 and is provided for convenience with the handle 68.

The machine is operated by turning shaft 31 which puts in motion simultaneously all the operative parts of the machine. The construction of the fly wheel and its operative parts enables it quickly to attain great speed so that its momentum will thoroughly regularize the action of the machine. When the rind cutter is to be used rack 180 and the wheel 18 are brought into connection with each other. The platform can be removed and replaced by a duplicate whenever an. other material is to be cut. The platform can also be lifted back and set when a fresh piece of material is inserted.
