EDWARD F. SMITH, OF ROCHESTER, NEW YORK, ASSIGNOR TO JOSIAH ANSTIOE, OF

ROCHESTER, NEW YORK.

SLICER.

Application flled November To all whom it may concern:

Be it known that l, EDWARD F. SMITH, a citizen of the United States, residing atltochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Slicers, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to im rovements in slicers, and pertains particulari to a machine in which a rotary swinging kni e is used.

The object of my invention-is to provide a slicer of this character, in which a rotary swinging knife is used, and in which the knife travels slowly during the cutting action and rotates very rapidly, and travels very rapidly during the return movement and rotates at a decreased speed, thus increasing the cutting power of the machine and making as rapid cutting machine as if the cutter traveled at the same'rate of speed during both the cutting and return strokes.

Another object of my invention is to provide a machine of this character, in which a more perfect feed is accomplished, and the adjustment of which is such that a slice varying from one-fiftieth (1 /50) of an inch to eighteen-fiftieths (18/50), may be readil cut, and the exact thickness of the slice read ily determined.

A further object of my invention is to provide a sharpening means for the rotary cutter, which is adapted to be set in operation during the operation of the machine, without interfering at all with the merits-of the cutter.

A still further object of my invention is to provide a cutter of this character, in which variousadjustments are obtained, as hereinafter fully described.

In the accompanying drawings, Figure 1, is an enlarged side elevation of my improved cutter showing the balance wheel and the hand-operating means removed, and showing the cutter at the end of the cutting stroke. Fig. 2, is an enlarged side elevation of the same as Fig. 1, only showing the cutter at the beginning of the cutting stroke. Fig. 3, is a top plan view of Fig. 2, with the cutter at the beginning of the cutting stroke. Fig. l, is a side elevation, looking from the op ositc direction, and showing the cutter at the end of the cutting stroke the same as Fig. 1. Fig. 5, is a transverse vertical sectional view. Fig.

'6, is a detached perspective view of the feed carriage, showing a piece of meat held there'- Speciflcation of Letters Patent.

on. Fig. 7, is an enlarged perspective view of that portion of the cutter showing the sharpener thrown down, and engaging the cutter for sharpening the same. Fig. 8, is an enlarged vertical sectional view of the r0 tary knife. Fig. 9, is a vertical sectional view through the lower end of the bladecarrying arm showing the'eccentricring for tightening the chain.

Referring now to the drawings, 1 represents a base which, as shown, is sup orted upon legs 2 and 3, which support the ass a sllght distance above the tab e or stand upon which the slicer is to be placed. The said base 1 has bolted thereto at its rear face, by means of bolts 4, see Fig. 5, the rearwardlyextending feed carriage supporting table 5 which is )rovided at its rear end with the downwardly extending foot 6, and supports the table in a horizontal plane. The base 1, flush with its forward or outer end, is providedwith an u wardly extending frame 7 which is adapte to'support the gear, etc., of the cutting mechanism, as I will now proceed to describe. The said frame 7, as shown, is of an enlarged form, and is provided adjacent one side with the opening 8 through which the meat or bread is to be fed from the feed carriage. The lower ed e of said opening 8 is in a straight horizonta line with the table 5, and'is provided with an outwardly-extending horizontal flange 9 of hard steel, and forms the surface against which the rotary knife acts in cutting. The said flange is in a horizontal plane with the n ma face of the carriage-supporting table 5.

10 frame 7, as the edge opposite that in which the opening 8 is formed,is provided with an outwardly and inwardl -extending arm 10 in which is journaled tie shaft 11 which carries on the inside of the arm 10 a pinion 12. The said shaft 11 on the outside of the arm is provided with a balance wheel 13 which is provided with the handle 14 by means of which the cutter is operated. The said arm 10 is )rovided at its upper edge with the upweirdly-extending curved arm 15 in which is journaled a shaft 16 to which is keyed on the outside of the arm, a gear wheel 17 which meshes with the small pinion 12. The said gear 17 carries on the inside thereof a larger gear 18 which meshes with a pinion '19 loosely carried '0 the shaft 20. The said shaft, as shown in ig. 5, is of an elongated form, and is journaled in an elongated bearing 21 carried by and made as a part of the upper end of the frame 7. The said pinion on the inside is provided with an elongated sleeve 22 which carries at its inner end the sprocket wheel 23, which is removably supported to the flange 24 by means of screws 25.

Loosely mounted upon the shaft 20 between the sprocket wheel 23 and the elongated bearing 21, is a downwardly-extending arm 26 which is fastened to the shaft 20 by means ofa set screw 26, and a pin 26 carried by the shaft, and resting in recesses in the arm, and said arm is curved outwardly at 27 so as to allow the free passage of the knife thereby, as hereinafter more fully described. The said arm, at its'extreme lower end is provided with an outwardly-curved or bent portion 28 which is provided with an enlarged central opening 75 extending transversely therethrough and in which rests a sleeve or eccentric 76 which is of a length equal to the thickness of the arm, as shown in Fig. 5. The said sleeve is provided with an eccentrically-arranged opening 77 extending longitudinally therethrough, and which forms the eccentric sleeve. Snugly fitting within said eccentrically-arranged opening is the shaft 29 which extends inward and upon which the rotary knife is mounted, as hereinafter more fully described. The portion 28 of the arm is provided with an opening 78 through which is screwed the set screw 29,

said set screw passing through a segmentally-arranged opening 79, and bearing directly against the shaft 29, and said set screw holds the shaft against the opposite side of the eccentric opening and frictionally holds the eccentricwlthin the arm. The outer end of the shaft has an opening therein into which passes a screw 80 for holding the washer 81 to the shaft, see Fig. 1, and thus limiting the outward movement of the ec centric within the arm. The shaft 29 as shown, extends inwardly beyond the arm and is provided with a sleeve 30 which is I loosely mounted thereon, and said sleeve 30 engages the inner edge of the eccentric 76 and limits the inward movement thereof.

From the foregoing description, it will be seen that by loosening the set screw 29 and turning the eccentric the shaft 29 is moved to or from the ivotal point of the arm, and the sprocket w eel carried by said shaft, as hereinafter more fully described, is also moved to or from said pivotal connection, and the chain assing over the sprocket wheel is tightened or loosened as desired.

The inner end of the sleeve is provided with a knife holder 31 which is rigidly secured thereto, and as shown, is formed of a diskshape and has its inner face slightly concaved. The outer periphery of said knife holder is provided with a circumferential oove or recess 31 in which rests the circu ar cutter blade 31 which is secured to the holder by 32, which is also rigidly carrie by the sleeve 30. Passing around the sprocket wheel 32 and the sprocket wheel 23 is a sprocket chain 33, and by means of the gearing heretofore described, it will be seen that the sleeve 30 is caused to revolve very rapidly, and thus the rotary knife is also caused to rapidly revolve.

The knife as before described, is carried by the swinging arm 26, and is ada ted to be swung across the opening 8, 8.1M the knife also rapidly revolving during its swinging movement. The shaft 16 on the inside of the arm 15 is provided with a crank arm 34 which has its outer end pivotally connected to a link 35, which has its outer end pivotally connected to the arm 26 at 36, which is at a point intermediate its ends, and thus the arm 26 is reciprocated back and forth across the opening As shown in Fig. 1 of the drawings, the knife is at its full outer stroke and the continued rotation of the gear 17 causes the pivotal point between the arms 34 and 35 to move off of a dead center, and the positioning of the shaft 16, 20 and the pivotal connection of the swinging arm 26 is such that the link 35 allows the arm 26 to have a more.

rapid motion, thus allowing the same to travel backward across the opening 8 at a much greater rate of s eed than it travels forward, and bringing t e knife back beyond the opening 8, so that the meat or bread may be fed forward through the opening. The backward movement of the knife being in the same direction of the travel of the gear 23, it will be seen that the knife will rotate at a loss rate of speed during its backward movement than the forward movement, thus increasing the cutting action of the knife during its forward movement.

The end of the link 35 beyond its pivotal connection with the crank 34, is provided with an enlarged extended end 36 which is provided with an outer bearing surface 37 which is adapted to engage the roller 38 carried by the pivoted arm 39 of the feed mech anism, and said surface is adapted to raise the said pivoted arm 39 and operate the feed mechanism, as hereinafter more fully. described. The said lever is shown raised by the extended bearing surface of the links in Fig. 2, while in Fig. 4, the said 'ivoted lever or arm 39 is in its downwar movement. The arm 39 is pivoted to an extension 39' of the frame 7. p

The arm 26 is provided with an outwardlyextending lug 40, to which is pivotally connected the arm 41, which is provided at its outer end with a sharpening material 42 which is adapted to e age the outer cutting ed e of the knife, and s arpen the same. In or er to hold the said end of the arm 41 carrying the material, firmly upon the blade, I provide the inner end of the arm with the two flat surfaces 43 and 44 at right angles to each other, and ad'acent said arm' is a flat leaf-s ring 44' whic is adapted to bear upon said at surfaces of the arm 41, and thus said arm is eitherheld in the'position shown in Fig. 1, or in the position shown in Fig. 7, and in both positions the arm is firmly held.

The feed carriage supporting table 5 is pro- I vided with alongitudinally-extending groove or slot 44 in which rests or extends a longitudinally-extending rib 45 carried by the underside of the carriage 46. The said carria e COHSiSiSOf a fiat plate 46 which rests firm y upon the table 5, and carries the rib 45, but is held aslight distance above thesame by the ribs 47 and 48 at each side. The carriage adjacent its forward edge, is provided with upwardly-extending teeth 49 which extend entirely across the plate 46, and are adapted to enter and prevent the meat from slipping on the carriage. The. said carriage at each side adjacent its forward end, is )rovided withupwardly-extending ears 50 in which are rigidly secured the upwardly extending standards 51', whichare provided on their inner faces with the ratchet teeth 52. Slidably mounted u )011 said standard is a follower 53 which as pivotally secured to its under face, the engaging bar 54 which is provided with teeth 55 which are adapted to enter the meat and firml hold the same on the carriage. The sai bar 53, ad'acent the standards, is provided with u war ly-extending spring pawls 56 whic are normally spring held in engagement with the ratchet teeth 52 of the bars 51, and thus the follower is held in its downwardly adjusted position. The said pawls 56, as shown, are in the form of a trigger, and thus can be pulled down so that the springs 57 will hold the triggers in an inward position, so that the follower can oe readily raised forinsertin the meat or bread under the same. The ollower is provided with an operating handle 53 b means of which it raised for inserting the read or meat.

The table 5, adjacent one side, has a worm 58 rotatably mounted thereon, and said worm being in a plane slightly above the table. The carria e46 on the side ad'acent the worm, is provide w ith a horizontal y-pivoted member 59 which is pivoted at 60, and has its edge provided with worm teeth 61 which are adapted to mesh with the worm 58, and thus the rotation of the worm causes the carriage to be fed towards the knife. The said member 59 has a spring 62 connected to the end thereof, and so positioned that it will either hold the member in or out of engagement with theiworm. The said member 59 is provided with an upwardl extending operating pin 63 by means of w ich it can be readily thrown in or out of engagement with the worm. As shown, the worm is mounted in ears 64 carried by the table, and the inner end is provided-with a ratchet disk 65. The worm 58 adjacent one end is provided with a cut-away portion 58 which stops the feed of the carriage when the member 59 reaches the said space.

Loosely. carried by the extreme inner end of the worm 58 is an arm 66 which carries a pivoted pawl 67 which is normally held in engagement with the ratchet disk by means of the spring 68, and thus the upward movement of the arm 66 causes the pawl to rotate the ratchet disk, which in turn rotates the worm, and causes the carriage to be fed towards the knife. The arm 66 interme diate its ends, has )ivotally connected thereto at 69, the upwardly-extending link 70, which is pivotall connected at 71 to the arm 39, and thus t e u ward movement of the arm 39, as heretofore escribcd, causes the link 70 to rotate the ratchet disk and cause the carria e to be fed forward.

n order to limit the downward movement of the arm 66, I provide the arm 39 with an off-set 40, sec Fig. 3, and carried by the same pivot 71 on which the arm 39 is pivoted is an arm 72 which extends under the off-set 40 of the arm 39. The inner end of the arm 72 is provided with an opening through which a-pin 73 passes, and said pin enters one of the series of openings 74 carried by the frame 75 bolted to the frame 7. The said series of openings 74, as shown, are arranged concentric to the pivot 71 of the arm 72, and thus the pin 73 is ada )ted to .enter any one of said openings, as t e arm 72 is raised or lowered. It will be seen that the raising of the arm 72 supports the link or rod 70 in an u ward position, and does notgive as long a t row of the lever 70, and thus the worm will only be turned a slight ortion of a revolution and cause but a slight eed of the carriage. By placing the pin 73 of the arm 72 in the lower 0 ening of the series of openin s 74, it will e seen that the link 70 is al owed to drop, and thus the pawl engages the ratchet at a lower-point, and the upward movement of the link 70 will therefore be greater, and the worm is given a greater part of a revolution, and the carriage necessarily moves a greater distance, and increases the thickness ofthe slice. By this adjustment, as will be seen, the raising or lowering of the arm 72 one opening, increases or decreases the thickness of the feed, and there being a number of openings, it is seen that slices of slight differences may be cut, or a very thin slice or a medium thick slice.
