ni e END WEIGHT SUPPORTS AND CONTROLS FOR smcusc MACHINES Filed Mar. 18, 1959, Set. 0. 800,336 10 Claims. 01. 140-102 This invention relates to end weights in general for slicing machines and more particularly to an end weight supports and controls for a chute that is inclined to the vertical but otherwise substantially vertical to the path of movement of the knife blade of a slicing machine.

Airiong the objects of the present invention it is aimed to provide an improved end weight support the lower end of which will just clear the knife blade when in position to engage the article to be sliced and which will positively clear the knife guard when swung into inoperative position.

It is still another object of the present invention to provide an end weight support the lower end of which will just clear the knife blade when in position to engage the article to be sliced and which will not only positively clear the knife guard when swung into operative position but will also clear the chute supporting bracket when swung into its finally locked inoperative position.

These and other features, capabilities, and advantages of the present invention will appear from the subjoined detailed description of one specific embodiment thereof illustrated in the accompanying drawings in which:

Fig. 1 is a perspective of a slicing machine equipped with the improved end weight control in operative position.

Fig. 2 is a fragmental perspective of the slicing machine shown in Fig. 1 equipped with the improved end weight support shown in finally locked inoperative position.

Fig. 3 is an enlarged fragmental elevational view of the end weight support adjacent its lower cam in operative position.

Fig. 4 is an enlarged fragmental elevational view of the end weight support in engagement with its lower cam and moved part way into inoperative position.

i Fig. 6 is an enlarged fragmental elevational view of an end weight support adjacent its upper cam when positioned in its finally locked inoperative position.

Fig. 7 is a fragmental section on an enlarged scale on i the line 7-7 of Fig. 3.

In the embodiment shown there is illustrated a slicing machine such as disclosed in United States Patent No. 2,665,531 having a main frame 1 having an extension 2 provided with an opening 3 through which extends the arm 4 reciprocably slidablein the extension 2. The outer free end of the arm 4 is connected'to the conventional chute or article carrier 5 having two wings 6 and 7 forming a dihedral angle with one another disposed at an angle to the vertical but otherwise substantially vertical to the plane of the rotatable cutting knife 8 which is rotatably mounted in the gear housing 9 containing the driving connection between the motor 10 and the knife 8, the gear housing 9 and motor 10 being mounted on the main frame 1.

Adjacent the knife 8 and in substantial alinement with States Patent 2 the plane of the knife 8, there is disposed the gauge plate or platform 11. In practice the chute 5 is reciprocated across the gauge plate 11 and knife 8 into and out of cutting relation with the knife 8.

On the edge of the plate 7 disposed substantially perpendicular to the knife 8, there is formed the rod 12 mounted in the upper bearing ear 13 and lower bearing ear 14 extending from such edge of the plate 7. The lower edges of the plates 6 and 7 just clear the cutting knife 8 when the chute is moved across the knife 8 into cutting relation with the knife 8. There is provided a guard 15 consisting in the present instance of an inner plate 16 disposed above the central portion of the knife 8 from which extends the arcuate guard portion 17 enclosing the cutting edge of the knife 8 along its outer arcuate path of movement. The guard .15 alsohas extending from the same the short rectangular plate portion 18 adjacent the extension 2 of the frame 1. The guard 15 is connected to and supported by the driving connection, not shown, mounted in the gear housing 9. The upper faces of the plate 16, the guard portion 17 and the rectangular plate portion 18 extend slightly above the upper face of the knife 8. The lower edges of the wings 6 and 7, however, clear the upper face of the plate portion 16 in its movement across the sarne. The upper face of the guard portion 17 may, be slightly above the upper face of the plate portion 16 but since the chute 5 does not in its reciprocation move over to the guard portion 17, there is of course no danger of the lower edges of the wings 6 and 7 engaging the guard portion 17. v

However, since the upper faceof the arcuate guard portion 17 may extend into the path of movement of the pins 19 extending downwardly from the lower face of the arm 20 of the end weight, it is desirable that when the end weight is swung into inoperative position, that shown in Fig. 4 of the drawings, it is desirous that the arm 20 be raised so that the pins 19 will. clear the guard plate portion 17 when swung from its operative position into its inoperative position. 'For this purpose the lower car 14, see'Figs. 3, 4, and 5 is provided with a cam face 21 to cooperate with the fibrous projection 22 at the lower end of the arm 20 adjacent its cylindrical journal 23 slidably mounted on the rod 12. Above the car 14 on the rod 12 as many shims or washers 24 may be provided, three being shown, as are necessary to position the arm 20 and therewith the pins 19 so that they will at least clear the central guard portion 16 in operative position. When, however, it is desirous to move the arm 20 from the operative position shown in Figs. 1 and 3, into the position shown in Fig. 4, then due to the cooperation of the fibrous pin 22 and cam face 21, the arm 20 and therewith the pins 19 will be raised to clear the arcuate guard portion 17. Since the upper face of the rectangular guard portion 18 may be disposed in a plane still higher than the plane of the upper face of the guard portion 17, the journal 23, see Figs. 1 and 7, is provided with a boss 25 which will engage the free edge 26 of the plate 27 and obstruct the further outward movement of the arm 20 until the bearing 23 of the arm 20 clears the plate 27 and the projection 22 rides up on the cam face 28 formed by the upper edge of the plate 27, see Fig. 6. In order to cushion the upper movement of the bearing 23 relative to the ear 13, the spring 29 is provided below the ear 13. When the projection 22 rides along the cam face 28 the arm will be swung over, see Fig. 6 where the semi-circular projection 30 clears the semi-circular projection 31 formed on the boss 32, formed on and ex tending from the arm 4, see Figs. 1, 2 and 6. The projection 30 has a cam face 33 which is adapted to engage the cam face 34 of the projection 31 so that the pro- 3 jection 30 will ride over the projection 31 into the locking position shown in Fig. 6.

In the present invention advantage is taken of the position of the end of the wing 7 relative to the rod 12 forming the plate or extension 27 on the wing 7 and forming the cam face 28 to coo erate with the fibrous protection 22 to raise the arm 20 and clear the arm 4 before swin ing the arm 20 back into the finally locked position with the pro ection 31 as shown in Fig. 6, and also using the edge 26 of the extension 27 to cooperate with the boss 25 formed on the journal 23 of the arm 20 to bar the arm 20 from swinging around into contact with the arm 4 or in contact with the rectangular guard portion 18 and conseouentlv insure that the arm 20 will not be swung around to the finally locked inoperative position until the arm 20 has been raised above the cam face 28, and finally using the inner upper face of the car 14 ad acent to the wing 7 and which ear is a part of the portion 35 extending from the lower edge of the pl te 7 which face constitutes the cam face 21 to be engaged by the fibrous projection or button 22, see Figs. 3 and 4 to raise the arm 20 so that its pins 19 will clear not only the rectangular guard portion 18 but also the arcuate guard portion 17.

The parts of the machine to which the present invention rel tes are disclosed in the copending applications cases #27, #28 and #29 all executed on or about March 16, 1959, Serial Nos. 800,189, 800,188, and 800,272 respectively.
