MEAT-CURING MACHINE.

Specification of Letters Patent.

Patented July 21, 1918.

Application filed April 2, 1917. Serial No. 159,093.

To all tohom it may concern:

Be it known that 1, MICH EL F. SERVA- '1'I Us, a citizen of the United States of Amer My invention relates ,to meat-curing machines o'fthat kind inwhich means are provided for injecting brine or other liquid into the meat,. as in making corned beef or other similar products, and is in the nature of an improvement on the device covered by my priordPatent No. 1,126,579, granted January 26, 1 15.

An object of my invention, as herein disclosed, is to simplify and reduce the cost ofmanufacture of a machine of this char ac e Another object is to provide an improved construction and arrangement which will tend to render the machine more certain of operation and lessliable to get out of order.

It is also an object to provide certain details and features of construction and combinations tending to increasethe general efficiency and'desir; bility of a meat-curing machine of thisparticular character.

To the foregoing and other useful ends, my invention 'consistsin matters hereinafter set forth and claimed.

In the accompanying drawings Figure 1 is a Vertical section of a pail or receptacle for holding the brine, showing a meat-curing machine in side 7 elevation .therein,.em bodying the principles of my invention.

- Fig. 2 is a plan of the structure shown in Fig. 1. t

Fig. 3 is an enlarged vertical section of the mechanism of'said machine, showing the pump-plunger in elevated position.

Fig. 4 is a similar view showing the planger .in depressed position. Fig. 5. is anenlarged detail sectional VlOW of the upper end'of the needle or piercing member by which the brine is injected into the-meat- I Fig. 6 is a detail view showing a portion ofthe mechanism adjusted to limit the downward.movement of the plunger.

Fig. 7 v isasection on line 7 -7 in Fig. 2, with the .lower portion of the pm] or receptacle broken away for convenience of illustration, and showing the pump-mechanism tilted downward to the position which it occupies when the machine is not in use.

As thus illustrated, my invention comprises a receptacle A of any suitable character, having a top B of suitable shape and construction. The pump-cylinder C is removably secured by screws 0 to the top plate 1,,which plate has one edge thereof hingeconnected at 2 with the depending bracket 3, which latter has its upper end suitably secured to the cover B of the receptacle. The bracket 4 is rigidly secured to the under side of said cover, but the bracket '5 is pivotally connected at 6 with the under side of the cover, so that this bracket 5 is movable about said pivot in a horizontal plane. When the bracket 5 rests upon the lower end of the bracket i (see Fig. 1), a support is provided for the other end of the plate '1, so that the pump is supported in upright position. However, when the bracket 5 is swung about its pivot 6, so as to disengage the adjacent edge of the plate 1, the pump is then movable about its hinge 2 into the position shown in Fig. 7, so that the entire mechanism is depressed below the cover to prevent in ury thereto when the machine is not in use. The cover B has an opening 6 through which the upper portion of the pump-mechanism is movable.

'Said pump has a plunger D therein, and this plunger has a vertically disposedtube d rigidly secured thereto, and the upper end of said tube has a flathead or meat-rest E removably secured thereto. The needle or piercing member F is a hollow tube, of smaller diameter than the tube d, and arranged inside of the latter. The upper end of this member F is provided with outlets f for the brine or other liquid to be injected into the meat. The lower end of the roda is provided with a head 7 which bears against the under side of the plate 8, the latter being secured upon the plate 1 in any suitable'or desired manner. A shoulder 9 is suitably secured to the member F, and the latter has a lateral opening 10 which communicates through this shoulder with the tube 11 which extends horizontally a dis tancetherefrom. Thelower end of the tube F is screwed into the shoulder J, and the upper end of the rod a 15 screwed into this same shoulder. A compression-spring 12 is interposed between the top of the plate 8 and the bottom of the shoulder 9, so that the downward movement of the member F is yieldingly resisted by this spring. The lower end of the pump-cylinderqOis provided with an outlet-tube 13, and this tube is connected with the tube 11 by means of a flexible tube 14 of rubber or other suitable material. The lower end of the pump-cylinder has an inlet 15 provided with a depending rubber tube 16 which extends downward into the brine or other liquid in the receptacle. A ball 17, or other movable valvemember, controls the upper end of the inlet 15, allowing the liquid to enter the pumpcylinder, but serving as a check-valve to prevent the liquid from discharging through the same passage through which it entered. A spring 18 is interposed between the bottom of the plunger D and the lower end of the pump-cylinder, so that the downward movement of the plunger and its stem d, and the head E at the upper end thereof, is yieldingly resisted, whereby the plunger is auto matically restored to its normal or raised position after being depressed and released.

i I The plunger can be depressed until'the lower such is necessary or desirable.

end 6 of the head bears against the top of the shoulder 9, with the mechanism as shown in Figs. 3 and 4. The tube or stem dis, it will be seen, provided with

vertical slots

19 and 20 at the opposite sides thereof, so that it can slide downward without moving the shoulder 9 and the tube 11, thus permitting said shoulder 9 to remain in the position shown in Fig. 8, when the plunger is forced downward. A pivoted stop 19 is, however, mounted on the tube 11 in such position that it can be raised to engage with its free end the lower end 6 ofthe head E (see Fig. 6), thus limiting the downward movement of the plunger, relative to the shoulder 9, when lVhen the plunger is forced downward (see Fig. 4.), the spring .18 is compressed, and when the head E strikes the shoulder 9, any further movement will then'compress the spring '12, in the manner shown, the tube 1e flexing slightly to permit this mode of operation.

If, however, it is desired to limit the extent of'penetration' of the member Fin the meat,

7 the stop 19 is then swung upward (see Fig.

6.), and when the head E strikes. the upper .end of this stop, the relative movement between the head E andthe piercing member F.

willcease, and any further downward'pres- .sure. on the head E will then simply move the plunger and the member F downward in unison. q,

'In. operatlon, the sectlon"v of meat is brought downward upon thetop of the head E, and downward pressure will then cause the plunger to move downward in the pump, but the spring 12is strong enough to maintain the member F in its raised position, causing this member to penetrate the meat. The downward movement of the plunger will force the brine or other liquid out of the pump-cylinder and through the pipes and

tubes

11, 13 and 14L into the member F',

so that this liquid will finally be discharged through the orifices f into the meat. During this operation, should the point of the mem ber F strike a bone, this member would then be depressed, the spring 12 yielding to prevent breakage or'injury to the mechanism. WVhen the pressure is relaxed, the spring 18 then drives the plunger 1D upward, causing the brine or liquid in' the receptacle to be drawn upward through the rubber tube 16 and into the cylinder of the pump. Then when the pressure is again exerted down-' ward, the liquid in the pump is driven-out the ball check-valve or other device shown in the tube), so that when the plunger moves upward theliquid in the flexible tube 14; is not drawn back into the cylinder. It-will be understood, however, that this check:

valve, and the one which controls the inl'et of the cylinder, can be of any suitable form or character. V

What I claim as my invention is 1. In a meat-curing machine, a hollow piercing member having outlet means in the end-portion thereof, a pump connected to supply the curing liquid to said member, said pump having a plunger, anda meatrest associated with said member and rigidly connected to said plunger. v

2. A structure as specified, in claim 1, in which said pump has a tubular plunger-rod which forms a guide, and in which said member has an inlet connection which slides in said guide. i
