12 Claims. '(Cl. 146-102) This case relates to food slicing machines.

In general, the object of this invention is to increase the efficiency and practicability of a slicing machine by improving the various parts thereof.

Specifically, an object of the invention is to provide a novel clamping means for holding and feeding an article to be cut by the knife.

Further and other-objects and advantages will be hereinafter set forth in the accompanying specification and claims, and shown in the drawings, which by way of illustration show what is now considered to be the preferred embodiment of the invention.

In the drawings:

Fig. 1 is a view of the machine from the feeding side.

Fig. 2 is an end view gage plate side.

Fig. 3 is a detail view of the clamp.

Fig. 4 is a detail view of the clamp and carriage.

Fig. 5 is a front view of the clamp.

Fig. 6 is a rear detail view of the carriage and clamp.

Fig. 7 is .a view of a modified clamp, and

Figs. 8 and 9 are sections through lines 8-8 and 9-9 of Fig. 7, respectively.

Referring to the drawings in detail, the machine comprises a base 10 on which is fixedly mounted a motor 11 and a box frame and knife housing 12. The front or motor side of the housing is provided witha hub portion 13 for journaling the shaft 15 of a pulley 16 carrying a disk knife 1'7 and driven by a belt 18 from a pulley 19 on the motor shaft. To the upper edges of frame 12, a cantilever beam or frame 20 is secured by screws 21. The rear or feeding side of the frame 12 is closed by a cover plate 22 .remov-' ably secured to frame 12 by

screws

23 and 25.

Grindstones 30 and 33 are provided to sharpen the knife, a cover 35 being used to shield stone 30 when in retracted, non-sharpening position.

The cantilever beam 20 at its unsupported end has secured thereto by screws 50, a box housing and frame 51 for the gage plate mechanism. The support for the frame 51 is such that it is free of the base 10 and permits the slice receiving plate 52 carried by the base to extend beneath the frame. This makes it easier for the merchant to receive the slices, as his view is not obstructed as is the case when the gage plate housing is mounted directly on the base. It also provides a more sanitary construction, the plate 52 being easily cleaned and there being no corners in of the machine from the which meat particles or the like may accumulate.. Further, the area of the receiving plate may be made much greater than when it is necessary to limit it by engagement with a gage plate housing rising from the base, thus permitting a greater number of slices to be received.

The front or motor side of the gage plate housing is formed with a hub portion 53 (see Figs. 1 and 2). In the hub portion is journalled a shaft 55 fast to a cam disk 56 having three similar circumferentially spaced cam surfaces 57. In engagement with each cam surface is a roller 58, each rotatably mounted between a pair of lugs 59 extending perpendicularly from the rear of a gage plate 60. Adjacent each corner of plate 60, a tube 61 is fixed thereto which is slidably guided on a rod 62 secured to the housing 51. Springs 63 between the heads 64 of the rod and the closed ends of the tubes 61 in which the rods are located normally urge the gage plate towards the cam disk. Pinned to the exteriorly accessible end of the shaft 55 of the cam disk is a sleeve 65 carrying a handle 66 and a graduated segment 67. By grasping and turning the handle, the cam disk may be adjusted to present different portions of its cam surfaces to the rollers 58, the "springs 63 causing the gage plate to follow the contour of the cam surfaces and move in t a horizontal direction relative to the plane of the knife.

Mounted on the base in front of the gage plate and cover plate 22 are a pair of vertical posts '76 and 77 carrying between them a round rail 78. Below the latter is a flat rail '79 directly secured to the base. Rails 78 and '79 guide a carriage 80 for movement past the knife. The carriage is provided with a through opening 81 (Fig.

6) through which rail 78 passes and a guide lug 82 sliding on rail 79.

To ease the shock of engagement of the carriage with the posts 76 and 7'7; rubber or felt bumpers 83 are provided at each end of the carriage. Rigidly secured to the bottom of the carriage is a handle 84 by means of which the carriage may be moved. Secured to the right side of the carriage, as viewed in Figs. 1 and 4 is a rail 85, the upper and lower edges of which are V-shaped. A clamp 86 is guided on said rail for movement to and from the plane of the gage plate and knife. The clamp comprises a casting rotatably carrying upper and lower V- shaped rollers 8'7 riding on the edges of rail 85. A spiked plate 88 is secured by hand screws 89 to a ledge 90 of the clamp. Between the plate 88 and the surface of the carriage a porcelain plate or tray 91 is immovably mounted on the carriage. Casting 86 carries for cooperation with plates 88 and 91 a spiked clamp plate 92 fixed to the end of a square'rod 93. The upper end of the rod is pivoted.- on a pin 94 fixed within a slot or recess 95 cut in the side of a bar 96. The latter is slidably mounted in an opening cut through the post 97 formed at the upper end of the casting 86. To limit-the movement of rod 93 clockwise, as viewed in Fig. 3, the end of the rod has a projection 98 which engages the inner end of a handle 99 secured to the bar 96. The contact of the side of the rod with the lower wall 100 of the recess 95 limits the movement of the rod in the opposite direction.

At its lower end, bar 96 is providedwith a hole 101 in which is located a spring 102 (Fig. 5) bearing against a tab 103 formed on the end of a latch plate 104 extending at right angles to the tab. The latch is pivoted to the bar 96 at 105 and normally tends under the force of spring 102 to move counterclockwise, as viewedin Fig. 5, this movement being limited by contact of the side of the 93 and the latter may be moved out of the recess to position clamp plate 92 parallel to the gage plate 60 and permit it to serve as a pusher plate as indicated in Fig. 2 and in broken lines in Fig. 3.

The return movement of the latter clamp plate to horizontal position is prevented by contact between rod 93 and the top of lug 106. Post 9'7 is formed with a recess 107 in which is a spring 108 bearing on a dog 109 pivoted to the post. The upper end of the dog is adapted to enter a notch 110 in the bar 96 when the latter is in uppermost position and retain it in this position while an article is being placedon the carriage. By pressing on the tail of dog 109, the bar is released and drops by gravity onto the article. be actuated by the thumb of the hand grasping handle 99. The latter is provided with a guard plate 111 shielding the hand gripping the handle from the knife during movement of the carriage past the knife to slice an article.

- To guard the edge of the knife, a member 120' shaped to conform to the edge of the knife is fixed to the frame 12 between the knife and the receiving tray. The tray is cut away to the shape of the guard member to permit removal of the tray at right angles to the plane of the guard member.

The gage plate housing is capable of being supported solely by the cantilever beam 20 but to brace the housing an angular piece 122 is fixed at one end to the post 76, extends horizontally from the post and then vertically below the housing 51 to which it is fixed. The shape of piece 122 is such that it does not obstruct the view of the merchant during cutting operations or interfere with the reception of slices by the portion of the receiving tray to which it is adjacent. If desired, piece 122 may be omitted.

Figs. '7, 8 and 9 show a modification of the clamp carried by the reciprocatable carriage. In this modification the carriage is provided at the side adjacent the gage plate, with a lug ,135 tapped to receive the threaded end of a round rod 136. A nut 137 is threaded on the end of the rod so as to abut the side of lug 135 and thereby prevent accidental movement of the rod. An arm The dog may 9 138 is provided. with a sleeve 139 at one end fitting over rod'136. Rod 136 is tapped to receive a screw 140 between which and sleeve 139 is a friction disk 141, preferably of leather. The screw may be adjusted to provide sufilcient friction between the leather disk and the sleeve 139 to cause the clamp to stay in any adjusted pivotal position relative to the rod 136. The other end of the arm 138 is also provided with a sleeve 142 to receive the round rod 143 fixed to and extending from a casting 144, which is similar to casting 86 in the first modification. The rod is internally threaded at the near end to cooperate with a headed screw 145. Between the head of the screw and the end of the sleeve is a disk 146 pinned to the rod 143 and abutting the end of the sleeve and a spring washer 147 abutting the disk. By adjustment of the screw 145 more or less frictional pressure may be set up between disk 146 and the adjacent end of sleeve 142 and between the other end of the sleeve and the thrust shoulder 148 of the rod 143.

Casting 144', similarly to casting 86 of the first modification is formed with a 'post 149 in which is a square hole 150 to receive a square bar 151 pivotally carrying at its end a clamp plate 152. Post 149, bar 151, and clamp 152, are similarly constructed and cooperate as post 9'7, bar 96 and clamp 92 of the first modification.

While the invention has been disclosed as applied to constructions hereinabovedescribed', it will be understood that various changes within the scope of the invention may be made and applicant therefore desires to be limited only by the following claims.
