-3'Claims. 1

This invention relates to improvements in manually operated machines for cutting into slices, of varying thickness, of cooked meats, sausages, cheese and products of a similar nature and has particular reference to a machine of the said character wherein a circular knife is mounted upon a frame or base and rotated by the action of a reciprocally moving arm and mechanism upon the said arm which carries, co-acting therewith, a set 'of jaws comprising a hopper for holding the product to be sliced. The forward and downward movement of the saidarm brings theproduct to be sliced into contact with the edge of the said rotating knife and away from same when the handle is retracted. The said hopper comprises two jaws, one of which is immovably fixed to the lower, inner end of said arm in a manner as will be hereinafter described, and pivotally attached to the stationary frame at base. The second jaw is pivotally attached to the said fixed hopper jaw but operates with the said arm and holds the product .to be sliced ,in the hopper during the slicing movement and releases the said product at a predetermined point in the retractivemovement of the parts.

One object of this invention is to provide a manually operated slicing machineof the character described and which comprises a minimum number of parts, making same compact, light .in Weight and particularly desirable for .household use.

Another obj ect of this invention istheprovision of a machine of the character described in .which the parts are so designed andassembled that they may be readily and quickly cleaned. without dismantling or disassembling.

A further objectof this invention is .to provide a manually operated slicing machine of thecharacter described wherein a hopperhavingholding jaws is employed. The said hopper being adapted to hold theproduct to be slicedand .beingactuated by a reciprocally moving arm which is pivotally attached to thebase of the machine.

A still further object of this invention is the inclusion therein of aspring .means for holding theproduct .to be sliced. in the hopper during the cutting action and releasing the said ,product when the cutting action has been completed.

Another objectof thisinvention is theinclusion therein of .a gaugeplate to fixthe thickness of the slice to be cut and novelnieans .foradjusting the said gauge plate.

A further object of this invention is the inclusion therein of a rack and ratchet driving means for rotating the said knife, the said rackbeing 2 actuated by the reciprocal movement of the said operating handle.

A further object of this invention is the means provided therein, for changing the movement of the rack to reduce or accelerate the rotating speed of the knife.

Astill furtherobject of this invention islthe provision of a device in which the constituent elementsare so arranged'structurallyand functionally as to assure improved results withmaterials and members which may be manufactured at reasonable cost, may be easily assembled and known to me, but such embodiment is to be regarded astypical only'of many possible embodiments, and the invention is not to .be limited thereto.

The novel featuresconsidered characteristic of my invention are set forth with particularity in theappended claims. The invention itself, however, bothas to its organization and its method of operation, together .with additional objects and advantages thereof, will best be understood from the followingdescription of a specific embodiment whenread in connection with the accompanying drawings, in which:

'Fig. 7 is an enlarged fragmentary detail of the modification shown in Fig. 4 and is a partial section taken along the line l'! of Fig. 4.

Fig. 13 is a side view, partly broken away, show- I ing the working parts in its advanced cutting position.

Fig. 14 is a similar view, partly broken away and shows another position of the operating parts.

Referring in detail to the parts, II designates a supporting frame formed with an inclined side member I2 having a recessed portion which forms a pocket I3 within which a circular knife or cutter I 4 is rotatably mounted. Lugs I5 and It are formed upon the base of said supporting frame II to which the lower ends I? and I8 of a hopper jaw I9 are pivotally attached. An operating arm having a handle 2| and legs 22 and-23 is attached against the under side of said hopper jaw I9 and is held in place by means of a rivet 24 formed upon the leg 23 of the said operating arm 20. The said rivet '24 is adapted to engage within a corresponding, orifice 25 in the leg I8 of the said hopper jaw I9. A second rivet 26 formed upon the leg I! of the said hopper jaw I9 engage through an orifice 21 in the leg 22 of the said operating arm 29. (Figs. 8 and 11.)

The hopper legs I 'I and I8 are each formed with studs or bosses 21 and I8 respectively which are flattened along part of their peripheries as at 29 and 39 and are adapted to engage the

legs

22 and 23 of the said operating arm 29. The said. flattened portions of the bosses, together with the

rivets

24 and 26 coact to hold the said operating arm securely upon the hopper jaw I9. The said hopper jaw I 9 and its connected operating arm 29 are adapted to oscillate as a single unit about the pivotal connections I5 and I6. A pin 3 Ibeing employed to complete the connection.

A second hopper jaw 32 having

legs

33 and 34 is pivotally attached to the legs I I and I8 respectively by means of a pin 35 around which a spirally wound spring 36 is mounted. The said spring ha adownwardly extending arm 3! the end of which engages a slot 38 formed in a web formation 38' which unites the two said legs I! and I8 of the hopper jaw I9. The opposite end of the spiral spring 36 has an upwardly turned arm 39, the upper end of which is turned out at a right angle 40, to engage in a slot 4! (Figs. 4 and 9) formed in a hopper jaw 32. The said spiral spring 35 exerts a force between the hopper jaws I9 and 32 whichtends to bring them normally together and hold a product to be cut by the rotating knife. The dot-dash lines in Figs. 10, 13 and 14 indicate a food produce which is to be sliced. 1

The angular end 49 of the spiral spring 35 is adapted to act as a bumper and limit the retractive movement of said hopper jaw 32. This limitation of movement is accomplished by the contact of the spring with a lug 42 formed upon an arcuate flange 43 upon the frame I I. A gauge plate 44 is adapted to rest upon the said arcuate flange 43 and is adjusted relatively with the rotating knife, by means of a four point helical mechanism acuated by means of a hand knob 45 (Fig. 11) which engage a cylindrical member 46, and enables full adjustment of the gauge plate by one quarter turn of the knob. The said cylindrical member 45 is rotatably mounted within a cup shaped portion 41 of the frame II and is rotatable therein. The inner edge of said cylindrical member is formed with four helical surfaces 48 which contact complementary helical surfaces 49 formed upon an annular flange 50 in turn integrally formed upon the gauge plate 44. A spring 5! is adapted to hold the parts together as clearly shown in Fig. 11, the spring 'being assembled in torsion to oppose the torsional component of the lineal spring force, due to the angularity of the helical surfaces. The hand. knob 45 is keyed to the said cylindrical member 46 by means of pins 52 which engage in grooves 53. As shown in Fig. 11, the gauge plate 44 is set to cut a slice of minimum thickness. By turning the knob 45, the said gauge plate may be moved outwardly until the opposing helical surfaces are brought closely together at which point a slice of maximum thickness may be cut by the rotatingknife I4.

The knife and its associated drive mechanism mountings will be best understood by the following description considered in connection with the illustrations in Figs. 5, 6, l0 and 12. A boss or stud 54, having a central bore 55, i shown in Figs. 6 and 12 and is formed in the pocket I3 of the frame II. Within the said bore 55, there is a bushing 56 and within the bushing is an internally threaded tubular member 51 to which the saidknife I4 is attached by means of the counter-sunk screw 58. The said tubular member5'! is held upon the boss 54 by means of a screw 59 and interposed washer 69. Rotatably mounted over the said tubular member is a ratchet member GI having pawl elements EZheId in recesses or pockets 53 (Fig. 5). The ratchet member BI is provided with pins 64 by means of which the said ratchet is tied to the knife Mas clearly shown in Figs. 6, 10 and 12. The said ratchet SI is given rotary movement by means of a gear 65 having internal ratchet teeth with which the pawls BI engage. A flat .V-shaped spring 61 being employed to keep the said. pawls rfiigrmally in contact with the said ratchet teeth The said gear 65 is activated or rotated by means of a rackIiS which engages'the gear 65 and is held in alinement therewith by the idler or guide pulley 69 (Figs. 10 and 12). When the ,rack 68 moves in the direction indicated by the arrows X, (Figs. 5 and 10), the gear 65 and its associated ratchet '6! and knife I4 will. rotate in the direction indicated by the arrows Xf. When the rack 68 is retracted or moves in the opposite direction, the gear 65 will turn in a reverse direction to that above indicated while the knife I4 will continue in its original rotary movement or come to a stop.

Reciprocal movement is given to the rack 68 through its attachment at ID or I I, which attachment is fixed by the reciprocating pin I2 or 13 clearly shown in Fig. 11 wherein the pin I3 is shown in engagement with the rack 68 at II, the pin 12 being retracted by a rocker arm I4 pivoted at I5 tothe Web 38'. Obviously, withthis rocker arm connection, when the pin I3 is pushed into action the pin I2 moves out of action as indicated. When the pin I3 is pushed in and connection is made at II, between the rack 68 and hopper jaw I9 the relative position of the said rack is as shown in Figs. 10 and 13. Fig. 10 shows the retracted position of the operating parts and Fig. 13 shows the position of the operating parts at the end of the forward or cutting movement. The connection of the rack 68 with the hopper jaw at H as just described imparts a high speed rotation to the knife Hi. When, however, a slower speed of rotation to the knife is desired, the parts are retracted until the rack 68 rests in the stop 16 as at 11. When the operating parts are in the position just described, the pin 12 is pushed in to make a connection between the rack 68 and hopper jaw l9 at 18 at the same time disengaging the said rack and hopper jaw at H. With this last named connection of the rack and the hopper jaw the operating parts, when the operating arm 20 has been moved forward, assume the position shown in Fig. 14. This arrangement imparts a slow speed to the cutting knife 14 and is desirable for slicing certain types of products. If desired the pin 12 may be shortened so that it does not connect to the rack 68 when pushed in, thus allowing the said rack and the knife M to remain stationary when the operating arm is moved forward. In which case the pin 12 serves only to cause retraction of pin 13.

To prevent the accidental displacement of the

pins

12, 13, the pin 72 is formed with

annular grooves

19 and 88 which engage the lower leg 31 of the said spring 36.

In Figs. 4 and 7 there is shown a modified form which dispenses with the rack 68 and driving gear 65. In this embodiment the gear 65 is replaced by a cylindrical member or drum 8| which rotates freely about the ratchet member BI and has internal ratchet teeth similar to the teeth 66 of the gear 65. A spiral spring 82 is attached at one end to the said drum 8! as at 83 (Fig. 4) and at its outer end is attached to a pin 84 upon a lug 85 which is formed upon the stud 54. A wire, flexible cable or cord 86 is wound over the said drum at one end and at its other end is attached to a pin 81 upon the leg [8 of the hopper jaw l9. The said cord 86 passes around an idler or guide pulley 88 which is rotatably mounted upon a boss formed upon the frame I l.

Suitable markings 89 may be provided upon the cup shaped portion 41 on the frame I l to indicate various positions or settings of the gauge plate 44 and a setting mark 90 may be provided upon the knob 45 to aline with the markings 89 as the knob is turned.

A portion of the wall of the pocket I3 is cut away as at 9| (Fig. 2) to allow the slices, as they are cut from the food product in the hopper, to leave same and fall upon a shelf 92 from where they are discharged or taken from the machine.

A slideable plate 93 may be suspended from the upper edge of the said fixed hopper jaw I9 by means of a hooked end 94 and affords a means whereby small end sections of food products may be fed for slicing.

I claim:

1. A manually operated slicing machine for cutting slices from food products, comprising a base and supporting member, a circular knife r0- tatably mounted thereon, an operating arm mounted upon said base and supporting member and reciprocally movable thereon, a hopper having a fixed and a movable jaw mounted upon said operating arm, the said hopper being adapted to hold a food product and the said movable jaw coordinating with the fixed jaw adapted to hold the said food product in place, a rack pivotally attached at one end to the said fixed jaw, a gear rotatable upon the frame and activated by the said rack, a pawl and ratchet upon the said rotatably mounted knife coordinating with said gear and rack to rotate the said knife, a spring means engaging between the said fixed hopper jaw and movable hopper jaw adapted to hold the movable hopper jaw in gripping contact with a food product in said hopper and a hand hold upon the said reciprocally mounted operating arm to move same to bring the food product into slicing contact with the said rotating knife.

2. The slicing machine as set forth in claim 1, wherein the said rack has interchangeable pivotal connection with the said hopper to change the speed of rotation of the said knife.

3. The slicing machine as set forth in claim 1, wherein a stop is formed upon the said base and supporting member and adapted to engage the said movable hopper jaw to limit its retracting movement and release its hold upon the food product in the hopper.
