ALFRED M. DEMU TI-I, OF CHICAGO, ILLINOIS, ASSIGNOB TO U. S. SLIOING MACHINE COMPANY, OF LAPORTE, INDIANA, A CORPORATION OF INDIANA,

WORK HOLDER FOR SLIGING-MACHINES.

Application filed November 10, 1917.

1 b all whom it may concern Be it known that l. ALFRED M. DEMUTH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in VVorkdiolders for Slic ing-Machincs, of which the following is a specification.

This invention relates to improvements in work holders for slicing machines. In slicing machines of the type embodying a rotary cutter and a reciprocating carriage, it is customary to provide a feeding plate mounted upon a carriage so as to intermit tently advance the article tothc cutter during the reciprocation of the carriage. In order to hold the article with relation to the feeding plate, spaced uprights are provided which are connected with the plate, and a clampin bar moves upon the uprights and cooperates with the feeding plate.

lVith this form of article holding means, and as generally constructed, it is impossible to hold the article so that it will be entirely out up or sliced, as it is necessary to leave a considerable port-ion of the end of the article which cannot be sliced, owing to the fact that the. clamping means must extend for a considerable distance over the end of the article to grip the same, and with the holding members which are provided with laterally projecting pins. the ends of the pins protrude into the meat and into the path of movement of the cutter before the end of the article is reached.

It is one of the objects of the present invention to pr vide an improved work holder which ill not only secure and hold the article by the very tip end while being cut so that the entire article may be cut up, but one which will also serve as an individual holder adapted to be readily applied to any machine and as readily removed therefrom, and which holder embodies an article support and. a cooperating clamping member.

A further object is to provide an improved article support adapted to rest upon the feedin plate so as to engage and be held in position by the uprights carried by the feeding plate, and an improved clamping member cotiperating with the support, said clamping member being also held in position and being movable upon the same uprights or guides which hold the article support, so that the article support may he read Specification of Letters Patent.

ily attached and detached from the machine adapting it for an individual article holder, rendering it unnecessary to remove the article from the holder after being once placed thereon.

To the attainment of these ends and the accomplishment of other new and useful objects will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the ac companying drawings illustrating this invention and in which;

Figure 1 is a front elevation, with a portion broken away, of an improved device of.

Fig. 10 is a detail top plan view partly in section of the cooperating clamping member.

Referring more particularly to the drawings, the numeral 10 designates a feeding plate usual in the type of slicing machine embodying a rotary cutter and a relatively reciprocating carriage, and which plate 10 is mounted upon the carriage to be intermittently fed or moved during the reciprocation of the carriage to advance the article to the cutter, as is usual in machines of this character.

Uprights 11 are carried by the plate 10 and are provided with teeth or shoulders 12 on the inner face thereof and extending lengthwise of the uprights.

This plate 10 is usi'ially inovided 'ith pins or projections 13 extending above its upper face and upon which plate the article is adapted to be placed so that the pins will impale the article.

ith the present invention, the article is held in position upon the plate by means of a supplemental support let which may be of any desired size and configuration and may be constructed of any suitable material, the bottom of the support 14 is recessed or hollowed out as at 15 so that when the support 14: is placed upon the plate 10, the pins 13 on the plate willproject into the hollow portion 15 of the support and by means of which the support 14 is adapted to be placed upon any machine.

In the form of the invention shown in Figs. 1 to a, the support 14 is provided with upright portions 16 extending along the lateral edges thereof and the extremities of these upright portions 16 are deflected laterally as at 17 and if desired, the edges of the portions 17 may be curved as at 18 to form a suitable and convenient handle for gripping the support 14C to transport the same.

The portions 17 are provided with apertures therethrough and surrounding each of the apertures is an upwardly projecting boss or collar 19. The aperture and boss are located in such a position that the uprights 11 will pass therethrough when the support 1% is placed in position, and the front edge 20 of the support is arranged to stand flush with the front edge of the plate 10, as shown more clearly in Fig. 3.

The support 14 is provided on its under face with enlarged or projecting portions 21 having apertures extending therethrough in a direction transverse to the front edge of the support and pins 22 are provided and adapted to be secured to the support 14. These pins 22 may be of any desired size and length and the rear portions 23 thereof are preferably arranged at an angle to the pointed extremities of the pins, and are adapted to be driven into the openings in the portions 21. The front of the support is provided with a suitable recess communicatin with each of the apertures in the portions 21, so that when the portion 23 of the pin is seated in the aperture, the body of the pin will be seated in the recess so that the outer face of the pin will stand substantially flush with the outer edge 20 of the support 14:.

With this improved construction, it will be manifest that in the event that any one or more of the pins become broken or damaged, they can be readily removed by turning over the support 1 1 and striking the projecting extremity of the portion 23 of the pin, thereby driving the pin out of its seat without dismantling any of the other portion of the mechanism. A new pin may be readily inserted as will be understood- The support 14 may also be provided adj acent its rear end with upstanding pins 24 which cooperate with the pins 22 and impale the article to assist in holding the article in position.

A clamping member is adapted to cooperate with the support 14 and may be of any desired configuration, preferably comprising a body portion 25 of any suitable material, having apertures through its extremities through which the uprights 11 are adapted to pass. This clamping member may be provided with a face plate 26 constructed of any suitable material and which plate is provided with teeth 27 extending thereacross, and the teeth are preferably arranged so as to extend in a direction toward one end of the clamping member and in a direction in opposition to the action of the cutter upon the article so that when the article is being cut, any tendency of the cutter to move the article laterally, will be resisted by the teeth 27 of the clamping member and which teeth will be forced into the article by such action of the cutter. This plate 26 may be secured to the body portion of the clamp 25 in any suitable manner such as by means of fastening bolts or devices 28, so that the plate may be readily removed when desired.

The clamping member is provided with a series of depending pins or prongs 29, the rear portion of each of which is dcfiected laterally and is adapted to be seated in a suitable opening in the member 25 so that the outer face of the teeth, when the latter are seated, will stand substantially flush with the front edge of the clamp and also with the front edge of the pins 22, support 14 and plate 10. The pins 29 are of such a length as to impale the extreme end of the article, so that the entire article may be sliced up, permitting the cutter to operate in close proximity to the outer face of the pins. In order to permit of ready removal of the pins 29, the portion 25 of the clamp is provided with a longitudinal re cess or groove 31, into which the extremity of the portion 30 of the pins 29 projects, and the plate 26 is provided with a rib 32 adapted to project into this groove or recess which assists in holding the plate.

Thus it will be seen that when it is desired to remove any one or more of the pins 29, this may be readily accomplished by detaching the plate 26 which will permit access to be had to the extremity of the portion 30 of the pin 29, to drive the same out of the recess in which it is seated. The edge of the plate 26 is also adapted to stand flush with the outer face of the pins 29 and obviously the edge of the plate adjacent the pins may be provided with recesses to receive the pin.

A handle 83 is secured to the clamping member intermediate its ends and by means of which the clamp may be raised or lowered. In order to arrest the downward movement of the clamping member so as to protect the ends of the pins 29, and also additional pins Set which may be provided in the clamping member, the clamping mem her is provided with a recess 35 adjacent each of the uprights 11 and each recess is adapted to receive the respective bosses or collars 19, the recess being of such a size that when the boss or collar engages the bottom of the recess, the extremities of the pins 29 will be. prevented from striking the sup-port 14:.

In order to hold the clamp in its adjustedposition, suitable locking means is provided and the clamp is adapted to be looked upon the uprights or guides 11 of different machines, no matter whether the teeth 12 are arranged on the inside or the outside of the guides.

The locking means preferably comprises two members 36, 37, the extremity of each of which is provided with an opening 38 of a size to permit the upright 11 to pass freely therethrough and these members 36, 37 are adapted to move in a suitable guideway formed by members 39, 4:0, removably secured to. the member 25 of the clamp and the fastening bolts 40 by means of which the handle 33 is secured in position, are ad pted to pass through suitable elongated slots 11 in the members 36, 37 which serve as an additional means for guiding them.

The walls of the openings 38 adjacent the inner and outer faces of the uprights are deflected or inclined as at 42, d3 to form an edge which is adapted to pass under the teeth 12 so that when the teeth are on the inner side of the upright, as shown in Figs. land 2, and the members 36, 37 are moved into the position shown in Fig. 2, the faces 43 thereof will pass under the shoulders 12 and lock the clamp in position. mien the teeth are on the outer face of the uprights or guides 11 as in Fig. 6, the members 36, 37 will be moved in the opposite direction until the faces 42 of the openings 38 will pass under the shoulders 12 as shown more clearly in Fig. 6. In order to accomplish this movementof the members 36, 37, an operating handle 1 i is provided which is pivotally sup ported as at 5 .5, the extremity of th member 37 being pivotally connected as at 46 with the handle, and the extremity of the member 36 being pivot-ally connected as at il with the handle. In order to permit of a free movement of the members 36, 37 to accomplish the locking operation above de scribed, the end of the member 36 is preferably curved as shown so as to permit it to pass over the pivot 45.

lVhen it is desired to place the clamp in position or remove it from the uprights or guides, the handle ii is shifted to what. is termed a neutral position, at which time the clamp is adapted for free movement upon the uprights.

\Vith this improved construction, it will be manifest that no matter what type of machine the clamp is applied to, that is whether the teeth are on the inside or outside of the upright, the clamp will be secured in position by shifting the handle 4st to one side or th other of the neutral position.

In the form of the invention shown in Figs. 7 to 10, the support 49 provided with laterally deflected portions 50 which extend in a plane above the horizontal plane of the body portion of the support and is pro- 'ided with additional pins 51 which are flush with the front edge of the support as are also the pins and the pins 51 are adapted to engage any article which is of a size to project over the laterally deflected portion 50 of the support.

This support 49 is provided with suitable handles by means of which the support may be transported and with both forms of the invention, it will be manifest that if the article is once placed upon the support, it may be allowed to remain thereon as an individual holder so that the article need not be removed from the support after once being placed in position, and may be readily placed in the icebox on the support.

.lVith the form of the invention shown in Figs. 7 to 9 and in order that the pins 51 will not interfere with the operation of the clamping member, the clamping member is provided with a recess 54 adjacent each of the pins 51 to receive the latter when the clamp is moved in proximity thereto as shown more clearly in Fig. 10.

With this improved construction it will be seen that the support and clamping member are not only adapted to be held in position' and operate upon the same guides or uprights, which are already on slicingmachines of this character, but the position of the teeth. 12 on the uprights is immaterial as the securing member on the clamp is adapted for useoneither type of machine.

While the preferred form of the invention has been herein shown and described, it is to be understood that many changes may be made in the design and specific arrangement of the parts within the scope of the claims without departing from the spirit of this invention.
