IMPROVEMENT IN SAUSAGE-MACHINES.

Specification forming part of Letters Patent To all whom it may concern:

Be it known that I, HUGH P. RANKIN, of the city and county of Allegheny, and State of Pennsylvania, have invented a new and Improved Sausage-stutter; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specification, in which Figure l is a side elevation; Fig. 2, a plan view, partly in section; Fig. 3, a detail transverse section through line g 3 Fig. 4, a transverse section through line as w.

This invention relates to certain improvements in sausage-stuffers; and it consists in a barrel or cylinder pivoted upon trunnions on a frame-work, and provided with an adjustable nozzle. In said barrel moves a piston, which is rigidly attached to a screw-threaded rod, which said rod is actuated longitudinally in the barrel by means of a bevel-gear, which operates through a revolving sleeve and an adjustable screw-threaded segment. The latter, by engaging the threads of the pistonrod, converts the rotary motion of the sleeve into a longitudinal rectilinear motion of the piston, and a stud upon the frame-work engages a longitudinal groove of the piston-rod to keep the latter from turning.

In the drawing, A represents the framework upon which the stuft'er is'constructed, and B is the barrel, which constitutes the body of the stuffer, and in which the sausage is contained. Said barrel is provided with trunnions a a, which are journaled in open bearings 12 of the frame-work, so that the stuti'er may be either disposed in a vertical position to facilitate the filling of the same, or placed horizontally during the stuffing operation without taking it from the frame. '0 is a detachable nozzle, which is held to the barrel by a fastening, D. Said fastening is provided with cams e e and slots 0 c, which latter receive studs d d of the barrel, and the former serve to tigliten the connection and hold the parts together when turned. E. is

the piston, which is rigidly attached to the screw-threaded rod F. Said piston is provided with a valve, f, which opens into the barrel, and admits the air upon the backward No. 171,631, dated December 28, 1875; application filed J line 12, 1875. l

threaded segment, K, which said segment may be ln'adeeither to engage or be out of contact of the eccentric collar'L and screw M. When said collar is turned in one direction the segment K is brought 'into engagementwith the piston-rod,and a rotation of the crank imparts motion through the sleeve to the piston-rod.

When the said eccentric collar is turned in ment is withdrawn from the piston-rod, and the latter is free to be drawn back with the pistonprevious to filling" the barrel with a new charge of sausage. I

N are supporting-screws or stop projections upon the barrel, which, with its trunnions, support the same in horizontal position *upon the frame, and O is an adjustable arm, which is turned across the edge of the barrel to hold the same down during the operation of stuffin g.

- Having thus described my invention, what I claim as new is with a screw-threaded piston-rod, of arevolving sleeve and an adjustable connection, for gearing together or disengaging the same, as and for the purpose set forth.

2. The combination of the screw-threaded h, the revolving sleeve G, the threaded segment K, the eccentric collar 'L, and the gearwheels, substantially as described, and for the purpose set forth.
