SLICING-MACHIN E.

Specification of Letters Patent.

Application filed .Tanuary 4. 1919. Serial no. 269.637..

To all whom it may concern Be it known that I, ERNEST K. I-Ioomla citizen of the United States of America, residing t Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Slicing-Machines, of which the following is a specification.

The object of my invention is to provide a combined power and hand driven outfit which can be easily operated and is compact and efficient.

In the drawings Figure 1 is a plan;

Fig. 2 a cross section of the clutch mechanism;

Fig. 3 a plan of a portion thereof and Fig. 1 an elevation and section of the motor and gear reduction.

The numeral 1, represents, a standard slicing machine of the reciprocating carriage type which is well known in the trade. This machine carries a rotary knife 2, a reciprocatin carriage 3 and a feeding mechanism 1. Hrimarily the machine is operated by hand wheel 5, mounted on a shaft 6. Power is transmitted through this shaft and a train of gears to the knife and carriage. As the knife rotates and the carriage reciprocates, the feed mechanism feeds the meat or material to be out, toward the plane of rotation of the knife the predetermined thickness. This construction is old and well known.

Mounted on the machine 1, is an electric motor 7 having the usual armature shaft 8 which carries a coupling plate 9. This coupling late is provided with the usual flexible d1sk 10 which drives a worm 11, meshing with a worm wheel 12 carried in a housing 13. This housing 13 is secured to the base of the machine as shown at 14. Vorm wheel 12 is mounted on the end of a quill 15, which carries at its other end the male member 16, of a friction clutch.

This quill 15 is loosely mounted on the end of the machine knife driving shaft 17, which carries at its outer end a sprocket18, which drives knife 2. This shaft also carries a car 19 which meshes with a gear 20 carrie by shaft 6.

Splined to shaft 17, is the female member 21, of the friction clutch. This is adapted to slide on shaft 17, and either contact with or. disengage from the member 16.

A slot 22, is cut through shaft 17 and also through clutch part 21, and through this slot is a drive key 23. Extending through a hole 241 in shaft 17, is a rod 25, rigidly secured to key 23, and carrying at its outer end a washer 26 in contact with a spring 27, resting on a ball bearing 28, carried in a pocket in the quill.

Mounted in housing 13 concentric with shaft 17 is a threaded stud 29 carrying a hand wheel 30. This stud 29 is adapted to contact with rod 25.

The operation of the device is as follows: When it is desired to drive the machine electrically, the hand wheel 30 is turned so as to release stud 29 from rod 25. This allows spring 27 to draw the clutch member 21, in contact with clutch member 16, thus providing a driving connection between the motor and the knife driving shaft 17, through worm ll, worm wheel 12, quill l5, clutch 16, clutch 21 and driving key 23. Thus the entire driving mechanism rotates and the machine is driven.

Now when it is desired to stop the machine, the hand wheel 30 is operated so that stud 29 pushes against rod 25, compresses spring 27, and at the same time pushes clutch member 21 out of contact with member 16, thus entirely releasing shaft 17 from driving connection with the motor.

It will be noted now that if the machine is operated by means of the hand wheel 5, shaft 17 is driven by gear 19 and clutch member 21 rotates therewith; rod 25 also rotates as does washer 26, spring 27 and ball bearing 28. The quill stands still however and this allows hand operation of the machine without operating the motor driving parts.

In order to limit the throw of hand wheel 30, I provide a stop pin 31, and a plunger 32, which allows 1 turn of the hand wheel which is ample for all practical purposes. I also provide a felt washer 33 to prevent the oil in gear housing 13 from working along the quill.

I claim 1. In a slicing machine; a friction clutch and ear reduction consisting of a shaft; a member of said clutch being splined to said shaft, a quill mounted on said shaft and earrying'the other member of said clutch; a gear carried by the other end of said quill; a rod extending through said shaft and connected to the splined member of the clutch;

Patented July 29, 1919.

copies of this patent may be obtained for nected to the splined member of the elutch;

a ball bearing and spring interposed between said rod and quill; and means for operating said rod longitudinally substantially as and for the purpose set forth.
