SLIGE RECEIVER FOR SLCING- MACHINES.

Application (filed, June 23,

T 0 all whom t may concern.'

Be it known that I, JOSEPH FOLK, a citizen of the United States, residing at Laporte, in the. county of Laporte and State of Indiana, have invented certain new and useful improvements in Slice Receivers for Slicing Machines, of which the following is a specification.

This invention relates to a receiving table upon which slices are deposited as they are formed by a slicing machine, and it has for its object the provision of such a table which may be operated to arrange the slices in various relations to one another, and which shall be of improved construction and convenient and efficient in operation.

The invention is exemplified in the combination and arrangement' of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed out in the appended claims.

In the drawings,-

Fig. 8 is a horizontal section on line 8-8 of Fig. 7.

The present invention is especially applicable for receiving slices from a machine which deposits the slices broad side down on a receiving table. One such machine is shown in Patent No. 1,376,775, granted P May e, i921. j

In the drawings, the numeral 10 designates the frame of a slicing machine of any approved construction, having a reciprocating fly 11 for discharging slices therefrom in the manner described in the patent referred to above. The fly 11 is pivoted at 12 on the frame of the machine and is operated by a link 13. A pair of bracket 1922, Serial No. 570,368,

bars 14; are secured to the frame 10 and project forwardly therefrom. The bracket bars 14; are connected by a transverse bar 15, having a standard 16 mounted thereon. A runner 17 (Fig. 7) is mounted for vertical movement along the standard 16 and carries a horizontal bar 18, having a table 19 mounted thereon in the manner eX- plained in the patent mentioned above. A threaded shaft 2O is arranged adjacent the upright 16 and extends parallel therewith. A sliding toothed member or half-nut 21 is connected with the runner 17 in position to engage the threads on the shaft 20. A rod 22 connects the half-nut 21 with a hand lever 23, by which the half-nut may be disengaged from the shaft 20 to permit movement of the table 19 vertically along the standard 16. A. spring 24 normally presses the half-nut into mesh with the threads on the shaft 20. A plunger 25 8) is slidably connected with the bar 18 below the runner 17 and may be moved into and out of engage-ment with the opening 26 in the standard 16. To enter the opening 26 the plunger 25 must be projected through an opening 27 in the sliding halfenut 21. When the plunger is in the position shown in Fig. 8 the half-nut will be locked in its retracted position, and the bar 18 with the table thereon will be held against movement along the standard 16. The. opening 26 is arranged at the uppermost position of the table 19, so that' the plunger 25 may be used for locking the table in its uppermost position and for holding the half-nut out of engagement with the screw shaft 20 at this position. A knob or finger-piece 28 is connected with the plunger 25 for moving it into and out of its holding position.

The shaft 20 is 'journaled in the lower end of the bar 15, as shown in Fig. 6, and carries a pair of ratchet wheels 29 and 36 fixed on the lower end thereof. An arm 31 is ivoted on the shaft 2O above the ratchet wheels 29 and is connected by a link 32 with operating mechanism on the slicing machine, as described in the patent referred to. A pawl 33 is journaled on a pivot screw 34, which connects the arm 31 and the link 32, and a spring 35 normally presses the pawl 33 into engagement with teeth 36 on the ratchet wheel 30. Each movement of the pawl 33 will thus impart a slight rotary movement to the ratchet wheel 30 and consequently to the shaft 20. The amount of this movement is controlled by a shroud or cam 37 carried by a shaft 38 extending centrally through the shaft 20 and adjustable by means of a. lever 39 at the top of the shaft, Fig. 1. The disc 29 is provided with spaced notches 40 upon its periphery.y which cooperate with a dog 41 carried on the arm 31 opposite the dog 82. A fiat spring 42 engages a pin 4B on the dog` 41 and presses the nose of the dog against the disc 29 when the dog is in the full line position shown in Fig. 5. The dog 41 is movable into inoperative position shown in broken lines in that figure and when thus moved it is held out of engagement with the ratchet 29 by the spring 42. lVhen the dog 41 is in its operative position the shaft 20 will be rotated in short steps by the dog 32 until one of the notches 40 comes to a position adjacent the nose of the dog 41. rlhe next oscillation of the arm 31 will cause the dog 41 to rotate the shaft 2() an amount corresponding to the full movement of the arm 31. In this way the shaft 2O may be rotated in short steps which are interspersed periodically by longer movements. The shaft may be used for feeding` the table 19 in the manner described in the patent referred to. rllhis operation is produced when the dog 41 is moved to its inoperative position. the plunger 25 is out of engagement with upright 16, and the half-nut 21 is permitted to engage the screw 20. When thus operated, the slices will be piled in a single stack upon the table 19.

A different arrangement of the slices may be secured by sliding a paper 45- horizontally across the table 19. A roll of paper 45 is carried on a bar 46 supported by an extension 47 of the bracket members 14. The paper strip extends rearwardly from the roll 45 about a rounded edge 48 of the table 19 and thence forwardly across the top of the table and also across the top of the plate 49, which is arranged substantially in the plane of the table 19 when that table is in its uppermost position. Adjacent the forward end of the plate 49 a roller 50 is journaled in the frame 47 and is provided with corrugated ends 5l7 which engage the lower face of the paper at opposite edges thereof. The paper is pressed downwardly upon the corrugated ends 51 by rollers 52 carried on arms 53 and pressed against the roller by springs 54. The rollers 50 are secured to a shaft 55, which carries a sprocket wheel 56, as shown in Fig. 4. A second sprocket wheel 57 is secured to the shaft 20 above the threaded portion thereof and a sprocket chain 58 connects the two sprocket wheels. Since the sprocket wheels are in planes at right angles to one another the chain 58 will be given a quarter turn7 but the parts move slowly and it has 1been found. in practice that 4no difficulty is experienced in operating the chain in this position. 'will be seen that rotation of the shaft 2O by the ratchet mechanism described will impart rotation to the shaft and corsequently will feed the paper 45 forwardly over the tables 19 and 49 with a step by step movement in timed relation with the rotation of the shaft 20. Since this shaft is rotated after the deposit of each slice upon the table` it will be seen that the paper will be moved horizontally over the table after each slice is deposited thereon and the amount of such movement may be controlled by the handle 39 and the cam 37. luthis way the slices will be arranged upon the paper in overlapping relation to one another, which is an arrangement desired by the trade for the reason that it produces an attractive appearance and permits each slice to be seen by the customer. 1t will be understood that during this operation the plunger will be in the position shown in Fig. 8. to hold the table 19 in its uppern'iost position and prevent downward movement thereof by the screw 20. The slices may be arranged upon the paper 45 in a continuous series of overlapping` positions. lt is sometimes desirable, however. to separate the slices into groups to be wrapped in packages. To do this the dog 41 will be moved to its operating position which will then periodically impart an extended movement to the shaft 2O and consequently to the roller 50 i through the sprocket chain 58. The number of slices in a group will depend upon the spacing` imparted to the slices by the dog 32 and upon the number of notches in the ratchet 29. The groups of slices thus formed may be separated from one another by severing the paper between the groups. For this purpose a frame 6() is pivoted at 61 adjacent the forward end of the plate-49 and carries a wire 62 in position to enter a slot 68 formed in the plate 49. Wvhen the wire 62 is moved downwardly into the slot 63 it severs the paper positioned above the slot. A spring 64 normally holds the frame 60 in its uppermost position and a tension nut 65 is employed for regulating the tension in the wire 62. ln order to prevent overthrow of the parts driven by the screw 20 and to hold the screw against backward movement. a friction shoe 66 may be pressed against the surface of the shaft 20 by the spring 67, as shown in Fig. 6. The end of the crossbar 18 is guided in its vertical movement by a radius rod 68 pivoted to the frame of the machine at 69, as shown in Fig. 3.
