ILLINOIS, A CORPORATION OF ILLINOIS.
SLICING MACHINE.
Application filed April 29, 1922. Serial 1T0. 557,367.
To all whom it may concern:
Be it known that I, PATRICK J LUGEY, a citizen of the United States, and a resident of the city of South Bend, county of St.
5 Joseph, and State of Indiana, have invented certain new and useful Improvements in Slicing Machines, of which the following is a specification.
My invention relates to new and useful 1 improvements in slicing machines, and more particularly to a power driven slicing ma.- chine of the type in which a table reciprocates to and fro along the side of a rotary knife and a material holder or feed plate is 1 automatically slidable on said table toward the knife.
The main objects of my invention are, First, to provide means for properly deflecting or guiding the sliced material away from the knife, and without permitting portions of the slices or particles of material to wedge in between the deflector and the knife thereby creating waste; second, to provide means co-operating with the table and the feed plate for holding the material with increasing firmness as it is advanced toward the knife during the slicing operation; third, to provide means for automatically disconnecting the driving motor and to lock the machine in an inoperative position when the feed plate has completed its limit of feed; fourth, to provide means for automatically displaying a signal when said feed plate has reached its limit of feed, and to retain said signal displayed until positive action is taken; fifth, to provide a universally movable operating handle for conveniently and readily moving the feed plate.
These and other objects and advantages will become apparent from the following description taken in connection with the drawings, in which,
Fig. 1 is a side view of the upper part of a slicing machine with my improvements mounted thereon;
Fig. 2 is an end view, partly in section along line 2-2 of Fig. 1;
Fig. 3 is a plan view;
ig. 4 is a sectional view along line 44 of Fig. 2, showing the universally movable handle for releasing the driving mechanism of the feed plate; v
Fig. 5 is a vertical sectional view on line 5-5 of Fig. 3, showing the circuit breaking means, and the curved and elevated ridges on the corrugated plate;
Fig. 6 is a sectional detail showing the deflector engaging in a groove provided in the knife;
Fig. 6 is a sectional detail view of the modified from, showing the deflector engaging the knife inward of a defiectin ridge formed on the convex side of the kni e;
. Fig. 7 is a fragmentary detail view showing the mechanism for locking the reciprocating table when the feed plate has reached its limit of feed;
Fig. 8 is a vertical sectional view taken on line 8-8 of Fig. 7;
Fig. 9 is a fragmentary view showing the driving motor with driving connections and electric switches; and
Fig. 10 is a diagramatic view of the electric circuits and elements.
In the drawings I have shown 111 improvements applied to a slicing machine of well known construction, having a rotary knife 15 mounted on a housing 16 extendingupward from the base 17 of the machine, and a curved guard 18 and a round wire guard 19 are provided for said knife. The machine is also provided with the usual material tray 20 and back plate 21.
In the machines now on the market the means for deflecting the material from the knife as it is being sliced, generally consists of a curved shield, the edge of which is placed close to the convex side of the knife,
but particles of the sliced material generally get between said convex side of the knife and the adjacent edge of the shield thereby creating unnecessary waste and soil. and the thin slices are not properly deflected and are frequently stopped and broken. Iovercome these defects by providing means on the convex side of the knife, which positively guides the sliced material onto the outer face of said deflecting means. I have shown this means in Fig. 6 in the form of a roove 23 extending around the convex side of the knife, just inside of the beveled edge.
this groove I set the forward edge of the shield or deflector, 24 so that the forward beyond the forward portion 26' of the deflector 24, thereby causing the sliced ma- .terial to be positively guided from the beveled edge onto theouter face of said In many of the slicing machines now in use the reciprocating table has been provided with a corrugated plate adjacent the rotary knife to firmly grip the lower face of the'material advanced by the feed plate, van'd'to'prevent said material from being shifted away from the knife while said knife engages the material, said shifting of material causing uneven slices, however such corrugated plates do not prove effective because the upper edges of the ridges on the plate are no higher than the usual top of the main table, and after usage the portions of the ridges near the knife wear down even lower than the back portions.
It is my object to provide the reciprocating table with a corrugated plate which is actually effective and which will hold the material rigidly in position with increasing 'firmness as the material approaches the knife side of the table 30. This I accomplish by providing my table 30 with a cor- 'rugated plate 31 having ridges 32, which 7 and further b plate thus provide means which co-operate.
the grooves between said ridges 32, with in creased effectiveness, and will also be urged toward the knife by the curvature of said ridges, as the material is advanced toward the knife edge of the table by said feed plate. Said curved and elevated ridges with the corresponding grooves on said with the material holder comprising the press bar 35 and-its uprights 36, for holding or gripping the material with increased firmness as it approaches the table edge,
thereby producing slices of even thickness. The slicing means thus operates to out even slices, while the deflecting means co-operates therewith to move said slices smoothly and evenly from the knife onto the tray or receptacle.
I further provide my machine with means arranged on the reciprocating table and on the feed plate for automatically opening the electric circuit of the driving motor andsimultaneously closing a .circuit through a specially provided signal light, when the feed plate has reached its limit of feed, and
in addition also provideineans on said table and plate for automatically locking the table against-movement until the feed plate has been retracted. v
The co-operating means for opening the motor circuit comprises a curvedshoulder or cam 38 (see Fig. 3) formed by cutting a notch on the side bar 39 of the feed plate,
and the plunger 40 mounted in a pocket provided in the-side flange 41 of the table, said plunger being normally retracted by a spring 42 (see Fig. 5) but moved. outward by said cam 38 of the feed plate just as'said feed plate reaches its extreme limit of feed; and as the reciprocating table 30 moves over its guide bars 43 and 43', along side the rotating knife 15, to its limitof reciprocation, the outer head 44 of plunger 40 will engage the push button 45 of the bridge or bar which connects and simultaneously actuates the 3-way switch 46 of the conductor 47 leading to the driving motor, to open said circuit and cut out said motor, and actuates the 3-way switch 48 of the circuit 49 for the j signal light 50, to close said circuit and illuminate the signal light.
The electric circuits and elements that are especially suitable for my purpose, I have illustrated diagrammatically in Fig. 10, and
have indicated in part in Figs. 1, 2, 3, and 9. 5
This circuit comprises a suitable feed .wire or conductor 51, leading from any suitable source of power, and provided with asuitable switch 52 to cut out or throw-in the.
driving motor 53. The conductor 51 leads to a 3-way switch 56 connected with the conductors 57 and 57, which are connected with the 3-way switch 46 of the motor circuit 47, and the conductor 51- leads from said conductor 51 to a 3-way switch 58 connected with conductors 59 and 59' which are in turn connected with the 3-way switch 48 of the circuit'49 of the signal light 50.
A push button 55 is provided on a bridge A or bar which connects and simultaneously actuates the switches 56 and 58, in a manner like the bridge bar and its attached button 45 actuates the Switches 46 and 48. The
My means for looking .or retaining the table in its extreme position of travel comprises a hook 71 provided at the end of a bar 72 fastened on the machine base 17 with screws 73, or any suitableameans, said locking-means further comprises a pawl 74 slidably mounted in a. pocket provided in an enlarged outer end 75 of a curved lever 76 which is pivoted on a journal 77 provided on the end of a bracket 78 fastened on the reciprocating table 30 with screws7 9 or the like said pawl being urged outward in said pocket by a spring. 80 and being slidably retained in said pocket by a pin 81 passing through a slot in said pawl. A coil spring 82 is seated with its opposite ends in a pocket in said bracket 78 and-a pocket in ,aid lever, to urge the pawl end of the lever into retracted position; and a stop arm 83 and lug 84 are provided on said bracket to prevent'lever 76 from swinging too far in either direction. A bracket 85 is fastened on the feed plate 34 by means of screws or the like, and is provided with a short arm 86 and a long arm 87. hen the feed plate has reached its limit of feed during operation of the machine, the short arm 86 has passed the adjacent end 88 of lever 76 without actuating said lever, since said lever is normally tilted by spring 82, as shown in the full lines in Figs. 3 and 7, but the long arm 87 has engaged and moved said lever into operative position, as shown in dotted lines at the middle of Fig. 7 and as the reciprocating table then reaches its limit of travel past the knife, the pawl 74 will engage hook 71 on bar 72 and securely lock the table in this position. And when the feed plate has been moved backward by a positive manual operation the short arm 76 will engage end 88 of lever 76, which then extends straight over the table, as shown in the dotted lines in Fig. 7 and will thereby tilt the lever and, release the pawl 74 from hook 71, enabling the table to reciprocate when next the circuit is closed and the electric power applied by depressing push button 55, asabove described.
It will readily be seen from the above description of the circuit breaking means that it fulfills a long felt wantinasmuclras it cuts off the driving power of the machine immediately when thefeed plate has reached its limit of feed thereby overcoming the objectionable features of the electric or power driven slicing machine that are in use at present, inasmuch as there is no means in the present machine to automatically cut off the power whenthe feed plate reaches its limit of feed, but that these machines continue to operate and consume current without slicing material or doing useful work. The locking mechanism above described further assures, in conjunction with the circuit breaking means, that the table and plate will be retained int his position until positive action is taken, as by moving the feed plate backward over the table.
My means for moving the feed plate on the table is provided with a universally movable handle .90, having a ballhead mounted in a spherical socket.member -91 attached to the machine, said ballhead having a fiat face 92 which engages a head 93 mounted on a,
