6 Claims. (Cl. 146-102) This invention relates to the chutes of a slicing machine in general and more especially to the supporting means or support for a chute which is disposed at an angle to the vertical but substantially vertical to the plane of the rotatable cutting knife of a slicing machine.

Among the objects of the present invention it is aimed to provide a support for the chute on a slicing machine which is disposed at an angle to the vertical but substantially vertical to the plane of a rotatable cutting knife which chute can be swung away from the knife in the interest of removing the knife for cleaning or in the interest of cleaning the cutting area, gauge plate and knife when removal of the knife is not desired and in general in the interest of the flexibility of a slicing machine not only for cleaning but also for repairing parts of the same.

These and other features, capability 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:

i Fig. 1 is a perspective of a slicing machine equipped with the improved chute support in inoperative position.

Fig. 2 is a perspective of the same approaching operative position.

Fig. 3 is a fragmental side elevation showing the connection of the support in detail when the chute is in operative position.

Fig. 4 is a fragmental side elevation showing the connection of the support in detail when the chute is in inoperative position.

Fig. 5 is an enlarged fragmental perspective of a part of the connection for the chute.

Fig. 6 is a section on the line 6-6 of Fig. 3 on an enlarged scale.

In the embodiment shown there is a slicing machine having a main frame 1, having a housing 2, containing a motor which housing 2 has an opening 3 in the rear through which extends a first arm 4 which is slidably mounted in the housing 2. The arm 4 has an upwardly extending boss 5 and a downwardly extending enlargement 6. To the enlargement 6 there is pivotally connected the arm 7 of the chute 8. The chute 8 in the present instance consists of two wings 9 and 10 disposed adjacent to one another to form a dihedral angle between them to receive the article to be sliced. The lower edges of the chute 8 in operative position, that shown in Fig. 3, are disposed substantially parallel to the plane of the cutting knife 11 but clear of the same. When the chute 8 is so disposed in operative position, it will partly obstruct the gauge plate 12 and cutting edge of the knife 11 or else a part of the cutting edge of the knife 11 and the portion 13 of the knife guard 114 and consequently it is of course practically impossible satisfactorily to clean the gauge plate 12, knife 11, and guard 114 when the chute 8 is in the operative position shown in Fig. 3. In order to facilitate access to the gauge plate 12, cutting edge of the knife 11 and guard 114, it has been customary to entirely remove the chute 2,970,623 Patented Feb. 7, 1961 ice 8 and its connecting arms 7 from the arm 4. This is, however, cumbersome and the average attendant in a grocery store, butcher shop, or delicatessan is not qualified to remove and again replace the chute 8 and arm 7. In view of the foregoing the present invention was devised to eliminate any loose screw parts which might be lost and to eliminate the injury of the chute 8 and arm 7 when detached from the frame 1.

According to the present invention, the arm 7 is more or less permanently connected to the arm 4 being pivotally connected thereto but provided with an anchoring means to wit, the locking bolt 113 which has a knurled head 14, a shank 15 which extends through the intermediate web 16 of the arm 7 and is then threaded into the boss 5. The shank 15 is provided with a snap ring 17 disposed on the inside of the web 16 with the collar 18 on the outside of the web 16 to anchor the locking bolt 113 to the arm 7 even though it is freed from the boss 5 as shown in Figs 1 and 4. Preferably as clearly illustrated in Figs. 3 and 4, the locking bolt 113 is provided with a flared portion between the shank 15 and the collar 18 to cooperate with the conical seat in the arm 7. With this arrangement there is also provideda convenient location for the set screw 19 to adjust the position of the arm and therewith of the chute 8 relative to the plane of the cutting knife 11. The set screw 19 is threaded into the upper portion of the boss 5 as shown in Fig. 5 and set according to the adjustment determined. When the chute 8 is to be positioned in operative position, the set screw 19 is first set to effect the predetermined adjustment of the gauge 8 relative to the plane of the cutting knife 11 and then the locking bolt 113 screw threadly connected to the boss 5 as shown in Fig. 3. The set screw 19 determines the position of the arm 7 relative to the boss 5.

The arm 7 U-shaped in cross section has in addition to the web 16 the lateral webs or flanges 20 and 21 which extend on the outside of the enlargement 6 as shown in Fig. 6. To connect the flanges 20 and 21 to the enlargement 6, a pin 22 is passed through the bronzed bushings 23 and 24 in the flanges 20 and 21 respectively and then through the enlargement 6 as shown in Fig. 6 and thereupon a set pin such as the set screw 25 screwed into place through the enlargement 6 into engagement with the pin 22 to lock it in position.

The lower end of the enlargement 6, see Figs. 3, 4,

i and 5 has a clearance 26 for the stop such as the nose 27 at the lower end of the web 16 of the arm 7 which clearance 26 extends to the stop or projection 28 on the enlargement 6 to receive the nose 27 of the arm 7, see Fig. 4 to determine the inoperative position of the arm 7 and chute 8, the arm 7 being swung into operative position after the locking bolt 113 has been released from the boss 5. The arm 4, see Fig. 3, in the present instance is connected to the bracket 29 slidably mounted in the housing 2 by two bolts 30 extending through the openings 31 and 32 in the enlargement 6.

The parts of the machine to which the present invention relates are disclosed in the copending applications, all executed on or about March 16, 1959, Serial Nos. 800,336, 800,188 and 800,272, respectively.
