To all-'wkomit-may concern:

Be it known'that L'G nalvvmtn S'rApL- MAN, a citizen of the UnitediSt'ates, resrdmg at Chicago, in the county of Cook-and State of Illino1s, have invented certain new and useful Improvements in Sausage Stuffing Machines, of which thefo'l lowing is a specification.

This invention relates to improvements in eating ejector or plunger which operates to eject the filling matter from the and into the casings.

Here'tofore in machines of this character, it has been customary to employ"fibrous packing rings with the plunger or ejector,- with the result that after the machine has been used for a little w-l-iile, the animal matter which has been taken up by the packing or that adheres thereto decomposes,resulting not only in a very unsanitary construction, but withthe further resultthat a very disagreeable and obnoxious odor will be emitted therefrom.

To overcome these vdiflicultiesand objections and to provide an improved sanitary machine of this character, whereby a metallic packing ring may be "employed with the ejector or plunger and which ring is so connected with the plunger or ejector that access may be readily hadith'ereto to remove the same without dismantling the other parts of the ejector or'plunge'r, is one ofthe objects of the present invention. I

A further object is to provide an in1- proved machine of this character'in which the plunger or ejector may begmoved ,into a convenient positionfree ofthe cylinder so that it can be readily 'det'ac hedfromits op,- erating mechanism Without dismantling any of the other partsof the machine.

To the attainment of these ends, and the accomplishment of other new and "useful objects as'will appeantheinvention concylinder sists in. the features ofnovelty in substan tially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention andiaifwh'iclr- Figure 1 is a vertical longitudinal 'sec;: 7

Fig. 5 is a sectional view taken on line 5 5, Fig. 4,

Referring more particularly to the "draw? ings, the numerals 10 and 11 designate superposed non-communicating cylinders whichare supported in any suitable manner, preferably so that the cylinder 11 will 'extend below the floor line or supportl-Q while thebottoln of the cylinder-1 0 will be preferably tlisposed adjacent said :fioor line. Arranged to reciprocate in the cylinder 11' is a-pi'stonembodying two members 13, 14, the

bottom member 14 being provided with an open groove 1-5 extending therearound and the upper member 13 is provided with a flange l d-adapted to project into said groove.

The parts 13, 14 of the piston are secured together for "relative movement toward and away from each other by means of suitable fastening devices 17, such as screws which enter threadedportions 18 of the member 14: and are provided with heads 19 which areseated inrecesses 20 in the member 13.

' Packing rings 21 are arranged around the periphery ofthe member 13; and between the members 13 and 14:. i-ch this i1nproved.construction,it will be manifest that when pressure is exerted behind the piston inithe cylinder 11 to move the/same in one direction, the member 14: will bemoved toward the member 13 to press the-packing rings .21 and force them outwardly against the wall of the cylinder 11 to forma tight detachably connected to the other end of the rod 22am is adapted to, reciprocate in the cylinder 'The'rod 22' is of such a length Connected with the piston thus of metal and is split so that the ends '30 thereof which are inclined, will overlap to permit ready expansion and contraction of the packing ring. The packing ring is also provided with a conically shaped opening 31, adapted to receive the tapered portion 28 of the ejectorso that the packing ring will rest loosely upon the ejector.

The piston in the cylinder 11 is adapted to be reciprocated in any desired or suitable manner, preferably by means of fluid pressure which is supplied to the cylinder 11 by means of a suitable supply pipe 32 leading from a suitable source. A four-way valve 33 is provided for controlling the fluid.' Leading from the casing of this valve is a pipe 34 which discharges into the top of the cylinder 11 on one side of the piston therein and this pipe 34 preferably extends into the top of the cylinder through the opening 25 of the cylinder 10. Another pipe 35 leads from the valve casing and discharges into the bottom of the cylinder 11 as at 36 and on the other side of the piston therein. An exhaust pipe 37 also leads from the valve casing.

With this improved construction, it will be manifest that the valve 33 may be adjusted so as to direct the fluid on to one side or the other of the piston in the cylinder 11, causing the same to move upwardly or downwardly and the valve is also adapted to form communication between each one of the pipes 34, 35 with the exhaust pipe 37 to permit the fluid on one side of the piston to be discharged. This construction and operation is well known and it is thought that a further specific description of the same is not necessary.

The upper edge of the cylinder 10 surrounding the opening 27 is tapered or de flected as at 38 and the closure 39 for the cylinder is provided with a tapered recess 40 adapted to receive the edge 38- so that when the closure is closed, and drawn tightly in position, the interengaging parts willform a tight joint. The closure is pivotally connected (with the casing preferably by means of a pivot 41 which passes through an eccentric sleeve 42, the latter being mounted in suitable bearings 43 and held against rotation therein. When it is desired to adjust the part to takeup the wear, allthat is necessary is to loosen the eccentricsleeve 44 and adjust the same within its bearing. vIn order to hold the closure in an open position and support the same, a suitable stop or shoulder '44 may be provided which is adapted to engage the wall of the cylinder 10.

, Any sui talble fastenin means mabe provided for the closure, but preferably a U shaped ring or bail 45 is provided which engages over a projection 46 on the closure 39. This link is pivotally connected with a pivot pin 47 and the latter is secured to and passes through a suitable eccentric sleeve 48, the pin 47, extending beyond one side of the link 45 for the reception of an operating handle 49 which is secured thereto, and the eccentric sleeve 48 is j ournaled in a suitable bearing 50, o

With this construction, it will be manifest that when the closure is closed, and thelink 45 passed over the projection 46 of the closure, the operation of the handle 49 will rotate the eccentric sleeve 48 in its bearing and will draw the link 49 and closure 39 downwardly and the closure .will be securely fastened. V

The cylinder 10 is provided adjacent its upper portion with discharge outlet openings 51 and between whichpdischarge outlet openings, the pipes 34, and 35 are arranged so as to be compact and out of the way of the operators. Connected with these outlets 51 are discharge nozzles 52 on .which the sausage casings are slipped. Suitable valves controlthe discharge of the material through the outlets 51 and into the casings.

Vith this improved construction, it will be manifest that bothof the filling nozzles 52 may be employed at the same time either by the same or separate operators, and it will be further manifest that when it is desired to remove the ejector 30 or the packing ring 29 therefrom, all that is necessary is to open the closure 39 and move the ejector so that it willproject beyond the top of the cylinder 10, in which position the packing ring 29 may be lifted off of the ejector as it is only loosely held thereon. Furthermore the ejectorniay be readily detached from the piston rod 22 without dismantling any of the other parts of the mechanism.

With this improved construction, it will be manifest that a sanitary device is produced and all of the objections incident to the use of fibrous packing on the ejector have been obviated.

By extending the cylinder 11 below the floor line 12, the parts may becompactly arand described, many changes in the details of construction and in the design thereofv .may be made within the scope ofthe claims without departing from the spirit of this invention.
