WRENCH FOR ,ME AT-CHOPPERS.

SPECIFICATION forming part of Letters Patent No. 760,532, dated May 24, 1904.

Application filed March 25, 1904.

To aZZ whmn it may concern:

Be it known that I, AL IN J. GERHARDT, a citizen of the United States, residing at Milwaukee, county'of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Wrenches for Meat-Choppers, of which the following is a specification.

My invention relates to improvements in wrenches for meat-choppers.

The object of my invention is to provide a form of wrench adapted to be used for adjusting the annular holding-nut of meat-choppers similar to those shown in the patent to Baker, No. 339, 834:, dated April 13, 1886. In the meat-choppers of that class the meat is forced through a perforated plate which is held in position by a nut engaging the marginal edges of the plate and provided with both lateral and radial knobs, some of which are frequently broken in use.

My invention contemplates a form of wrench which can be used on machines of various sizes and which is adapted to engage either the lateral knobs or the radial knobs, as desired.

In the following description reference is had to the accompanying drawings, in Which Figure 1 is a rear view of a meat-chopper with my invention applied thereto in position of use and as it appears when engaging one of the lateral knobs of the holding-nut. Fig. 2 is a side view, partly in section, showing my invention as it is used for engaging one of the radial knobs on the holding-nut. Fig. 3 is a detail view of the adjustable fork for engaging the radial knobs.

Like parts are identified by the same reference characters throughout the several views.

In the meat-choppers of the above-mentioned type the shaft 1 is incased in a bearing-thimble 2. The wrench comprises a bar 0, having an aperture 4 near one end adapted to receive the bearing-thimble 2 and a slot 5 extending from said aperture 4 toward the end of the bar, the slot 5 being adapted to receive one of the lateral knobs 6 on the Serial No. 199,927. (No model.)

holding-nut 7. By adjusting the wrench, as shown in Fig. 1, with the bearing-thimble 2 entered in the aperture L and with the knob 6 projecting into the slot 5 it is obvious that the nut can be readily turned to remove or replace it in position of use. Where the knobs 6 are broken, as indicated in Fig. 2, a fork 8 is used to engage the radial knobs 9 on the ring 7 The fork 8 is provided with a shank 10, which passes through the slot 5 in the bar and is provided with aclamping-nut 11, which 1 when-turned up tightly against the bar will bind the fork forcibly in position. By loosening the nut 11 the fork 8 may be adjusted to any desired position, and thereby adapted to machines of various sizes. I/Vhen in use, one of the radial knobs 9 is entered between the arms of the fork, as indicated in Fig. 2.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A wrench for adjusting the holding-rings of meat-choppers, comprising the bar having an aperture near one end adapted to receive the bearing-thimble of the meat-chopper shaft, said bar being also provided with a slot adapted to receive lateral projecting knobs on the holding-ring of the meat-chopper.

2. A wrench for adjusting the holding-rings of meat-choppers, comprising a bar having an aperture near one end adapted to receive the bearing-thimble of the meat-chopper shaft, said bar being also provided with a slot adapted to receive lateral projecting knobs on the holding-ring of the meat-chopper, together with a fork, adjustably mounted on said. bar and adapted to engage radial knobs on the meat-chopper holding-ring.

In testimony whereof I affix my signature in the presence of two witnesses.

ALI/VIN J. GERHARDT.
