' SAUSAGE-STUFFIN G MACHINE.

Specification of Letters Patent.

Application filed January 9, 1907. Serial No. 851,498.

To all whom it may concern:

Be it known that I, EDWARD J .HALLAHANH a citizen of the United States, residing at Augusta,, in the county of Richmond and State of Georgia, have invented new'and useful Improvements in Sausage-Stuffing Machines, of which the following is a specification;

This invention relates to a sausage stuffing 'machine, and aims to provide a machine of such class with means hereinafter set forth to permit of the automatic return of the forcing piston and head by gravity when occasion so re uires.

A further ob ect of the invention is to pro vide a machine of such class with means for automatically discontinuing the operation ,thereobwhen the forcing piston and head have arrived at the limit of their stroke in one direction. I

A further object of the invention is to provide a machine of such class with means to prevent leaking of the motive fluid from around the piston during the operation of the -forcing piston and head.

A further object of the invention is to provide the forcing piston head in a machine of such class with a packing whereby the tight fit between inner face of the material containing cylinder and the piston head is above the top of the piston head thereby enabling the packing to' remove any matter adhering to the inner face of the cylinder.

A further object of the invention is to ro vide a forcing piston and head in a mac ine of this class with means whereby said piston and head can be readily removed when occasion so requires.

I A further object of the invention consists in providing a sausage stufii'ng machine which shall be simple in its construction, operated by motive fluid, preferably water, strong, durable, efficient in its use, conveniently operated, having its operation automatically stopped when occaslon so requires, readily set u and comparatively inexpensave to manu acture.

With the foregoing and'other objects in view, theinvention consists in the novel construction, combination, and arrangement of parts hereinafter more-specifically described andillustrated in the accom anying draw: mgs, wherein lsshown the pro erred embodiment of the invention, but it is to beunderstood that changes, variations, and modifications can be resorted to which come within the scope ofthe claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, wherein like reference characters denote corvlews, and in which Figure 1 1s a vertical sectional view of a sausage stufiing machine in accordance with this invention. Fig. 2 is a plan with the material containing cylinder removed. Fig. 3 is a plan of the automatic stop mechanism responding parts throughout the" several with certain portions of the machine shown in dotted lines. Fig. 4 is a perspective of the automatic stop mechanism. Fig. 5 is a sectional view of the piston packing. Fi

'6 is'a sectional detail of one of the chec Fig. 7 is a plan of one of the checkvalves. valves,' and Fig. 8 1s a detail showing the handle for removing the forcingpiston and head.

Referring to the drawings b reference characters, 1 denotes the materia containing cylinder which is open at its bottom and provided atits top-with a cover. 2 detachably secured in position by the holdfast device 3. Communicating with the to of the cylinder 1 is a discharge spout 4 to w ich the sausage casing is attached, and the said spout'4 18 provided with a suitable cut-ofi 5.

Within the cylinder is'arranged a reci ro- A catory forcing 1piston to which is secure the plate 7 a eather packing cu 8 whic projects forwardly of the piston ead 6 so that the joint between the cylinder 1 and the piston head will be had above the upper face thereof. The projecting ortion of the cu 8 acts as a means to clean t e inner face of t e cylinder from any material adhering thereto when the piston is reciprocated in one direction, that 1s, during the forcing stroke of the piston. The head 6 is formed with a screwthreaded openin 9 in which can be secured the handle 10 (Flg'. 8) so that, when occasion.

member 12 to.,the base.15 as well as acting turn carrying the hea as a closure for the lower-end of said hollow cylindrical member 12. The cylinder 1 is orted upon the base 15 by the uprights 16 which are fixedly secured at their lower ends to, the base and at their upper ends to the cylinder.

Mounted upon the base 15 is .a water reservoir17 which is adapted to communicate with a pair of forcing pum s 18, 19 operated in alternate directions. h'e reservoir 17 further communicates with the interior of the hollow member 12. The pum s18 and 19 also communicate with the ho ow member 12 for supplying a motive fluid thereto thereby elevating the iston 11, the latter in (i 6 therewith and forcing the material from the cylinder 1 through the spout 4, thatis, if the cut ofi 5 is open. The communication between the member 12 and the pumps 18 and 19 consists of'a pipe 20 which opens at one end into said member '12 and at its other end is connected by the 'cou ling 21 to a pipe 22, the latter being attac ed to a three-way coupling 23 which in turn is connected to a pipe-section 24. The pipe section 24 is connected by the coupling 1pipe section 26 which'communicates with a c eck-valve casing 27, the latter being in communication, by means of the pipe section28, with the pump 19. The check valve cas' 27 is connected'by a pi e section 29 .to a c eck valve casing 30 an communication between the latter and the pump 18 is check valve casings 34 and 35,

had b the pipe section 31. Communicating 3 5 with e pumps 18 and 19 are respectively the pipe sections 32 and 33 which open into the v respectively. The check valve casing 34 communicates with 5 a three-way coupling 36 through the medium with respect-to the "of the pipe section 37, and the three-way cou ling 36 is connected with the check valve casing by the ipe sections 38 and 39. Connected to the t rec-way couplin 36 is a pipe 40-which communicates witht ereservo1r'1'7. Within the check valve casings 27, 30, 34, and 35 is positioned a-check valve 40 6), and a stop 41 consisting of a bar which extends across the casing is provided to arrest the movement of the valve 46 when shifted from off. its seat 42. The valves 40 in the casings 30 and 34 operate alternately valves in the casings 27 and 35. This is owing to the. fact that when the latter being in a reservoir the pump 19 is suck- 'e three-wa coupling as connected thereto one en of a ipe 42 which communicates with a cut-.0 43, communication with the 17 through the medium of the pipe section.44. From the foregoing arrangementof iping it will be evident that, when the cut-o 43 is closed, the motive fluid will be sucked from the, reservoir 17 and forced into the member the pump -18 is forc' mg or vice versa. 23 i1 12 and consequently elevate the piston 11, v,

provided with an 0 which in turn will carry the head 6 therewith and force the material Tom the cylinder. If it be desired to lower the piston, the cover 2 is removed, the cut-off 43 opened, and the piston will then lower by gravity and at the same time force the motive fluid out of the member 12 and into the reservoir. This will be evident owin to the fact that the check valve 40 (Fig. 6 in check valve casing 27 will be closed and the water will ass throu h the pipe sections 20, 22, 42, an 44-from t e member 12 into the reservoir 17 Ifthe cutoff 43 is closed and the pump started the water will be drawn from the reservoir through pipe sections 40,36, 37,38, 39, 32 and 33, into the pumps and from the pumps forced through the pipe sections 31, 29, 28, 24, 22 and 20 into the member 12, thereby elevating the iston, which in turn will carry the piston hea therewith. I I

The means for o sists of a driven sha t 45 carryin a loose pulley 46, 47, respective y, and provided. with a, gear 48 which meshes with a gear 49 carried by the pump shaft 50, the'latter being suitably connected to the pumpsso as to cause them to alternately-o era'te with respect tov each other. tion for this urpose may be employed; The

crating the pumps conpulley 46 is riven by a belt 51 connected to a prime mover, not shown.

A means is rovided to prevent the motive fluid from leakin past the piston, and such means consists o a double collar 52. through which the (piston 11 extends, and in the channel forme by the outer and inner portions 54, 55, respectively, of the collar an expanding ring 56 is positioned for retainin "the portions 54 and 55 (Fig. 5) of the co ar separated. The lower eilds of the portions 54, 55 of the collar are beveled, as at 57. The collar is formed of suitable flexible material, preferably recess 58 formed in the-member 12 near the top thereof. The double collar or what may be termed packing 52 is retained in the recess 58 through the medium of a screw-threaded cap 59 which engages with the periphery of the member 12 atthe top thereof and 1s ening through which the piston 11 passes. f the motive fluid should pass upwardly around the piston it would entei' the recess, and, consequently, ex and the collar 52 and cause the portion 55 o the collar to snugly fit the pistonsothat leakage would be prevented.

The means for automatically discontinu ing the operation of the machine when the forcmgpiston has arrived at the limit of its stroke in one direction consists of an automatically o erable belt shifting device for Any suita 1e connecleather, and is mounted within a a fixed and v i moving the elt 51 from off the fixed pulley 46 upon the loose pulley 47 so that the operation of the driven shaft 45 will be discontm'ued. The said means consists of a bracket 60 which issecured to the periphery of the mg plate 62 which is a ertured, as at 63.

referred to.

The upper face of the p ate 62' is provided with a pair of vertically extending apertured protuberances 64, 65, the o ening in the protuberance 64 being of less iameter than the 0 enin in the protuberance 65. Extending t 011 the protuberances 64, 65 is an actuatin ar 66 having an enlar ed portion67 whic extends through the e arged opening in the protuberance65. Mounted upon the bar66 and interlposedbetween the enlarged portion 67 and t e protuberance 64 is an expansive spring 68 which when tension thereof is released is ada ted to shift the bar 66 in one direction for a unction to be hereinafter The bar 66 is retained in normal position so as to store tension in the spring 68 through the medium of a trigger 69 pivoted, as at 70 to the plate 62, and extending in the path of the enlarged 'ortion 67 of the rod 66. The lower end of t e trigger 69 is pivotally connected to a vertically movable shifting bar 70 therefor.- The latter extends throu hthe lug 61 and is adapted to be engaged y a trip member 71 carried on the lower end ofa hollow rod 72 projecting from the lower face of the piston 6 and travelin upon a guide 73 which consists of an upright fixed to the base 15.

Pivoted u on the plate 62, as at 74, is a belt shifter ormed of a handle portion 75 and apairof bars 76, 77, the latter being substantiall L-sha ed and having one portion thereo secure( to the formerso as to form the belt shifter with a yoke-shaped ortion 78 which is ada ted to straddle the Eelt 51. The bar 76 is a a ited to be engaged by the actuatin rod 66 w en the spring 68 is released, whic will cause the actuation of the belt shifter so that the belt will be moved 4 rom the fixed pulley 46 and upon the loose ulley 47. The movement of the arm 76 is imited in either direction through the medium of a stop 79 formed by a slotted member integral with the upper face of the late -62 at one corner thereof. From the Foregoing construction and arran ement of parts it is evident that, when t e piston arrives at the limit of its stroke in one direc-. tion, the trip member 71 will engage the rod and shift the trigger 69 vefipn its pivot so that the nose of the trigger be moved out of the path of the enlarged portion 67 of the actuating bar 66 thereby freeing said bar to the action of the spring 68 so t at the said bar 66 will-be actuated an'd the'reby move the belt shifter so as to shift the belt and discontinue the operation of the machine. I he return of the belt shifter is had manuall which also cocks the trigger. The be t shifter also provides a means for discontineating uing the operation of the machine at any time when occasion so requires irrespective of its operation by the trip.
