FLUID INJECTION MEANS
Nicholas J. Dziedzic, Chicago, Ill., assîgnor to In
dustrial Patents Corporation, Chicago, Ill., a
corporation of Delaware
Application July 29, 1935, Serial No. 33,701
18 Claims. (Cl. 99-256)
This invention relates to- a fluid injection tion, partly in section, taken on line 6--6 of
means.
One of the objects of this invention is to pro
vide an improved ñuid injection means.
Another object _of this invention is to provide
a device for injecting a curing medium into the
hollow interior of the bone of meat cuts.
Another object of this invention is to provide
a device for injecting a curing medium under
10 pressure into the hollow interior of the bone of
meat cuts whereby it will be forced through the
articular cartilage to the flesh surrounding the
bone.
Another object of this invention is to provide
15 a device for introducing a curing medium into
the bone, the ñesh or through the vascular> sys
tem of cuts of meat.
Another object of this invention is to provide
means for injecting a curing medium into the
20 marrow of bone to prevent souring of the marrow.
Another object of this invention is to provide
a device utilizing a needle for the injection of
a curing medium into the marrow of bone, having
novel means for preventing stoppage and clog
ging of the needle during the injection thereof.
Another object of this invention is to provide a
needle for introducing a curing medium under
pressure into cuts of meat, having means engage
able with the outer surface of the product to pre
30 vent leakage of the curing medium at the point
of insertion of the needle.
Another object of this invention is to provide
a needle for introducing a curing medium into
35
cuts of meat having means for positively limiting
the insertion thereof.
Another object of this invention is to provide a
device of this character having adjustable means
for varying the depth of insertion of the needle.
Other objects will be apparent from the de
40 scription and claims which follow.
In the drawings, similar reference characters in
the several ñgures designate similar parts.
Figure 1 is a side View of a preferred embodi
ment of the present invention, partly in section,
45
showing the needle closed, ready for insertion.
Figure 2 is a side view, partly in section, show
ing the needle as it will appear whenin operation.
Figure 3 is a plan view of Figure 1.
Figure 4 is a side elevation, the sealing means
50
being shown in full lines in a rearward position
and in dotted lines in a partly forward position.
Figure 5 is an end View of the barrel portion of
the device taken on line 5-5 of Figure 4.
Figure 6 is a transverse view of the barrel por
55
Figure 4.
The device shown in Figure 1 comprises a barrel
portion I and a stock portion 2.
Barrel I comprises hollow cylinder 3 threaded
within stock 2 at 4. Piston 5 is slidably mounted
within cylinder 3 and is provided with compres
sion rings 6 to snugly engage the inner wall of
cylinder 3. The movement of piston 5 is limited
at the stock end of cylinder 3 by annular boss 'I 0
and at the needle end of cylinder 3 by plug 8
threaded within cylinder 3 at 9.
Plug 8 is provided with opening I0 for the re
ception of tubular injection needle ||, which eX
tends outwardly from cylinder 3. Needle ||,
adapted for insertion into meat products, is se
curely held within opening I0 by plug I3 threaded
within plug 8. Elongated pin |4 is secured at
one end to face 20 of piston 5 at I5. When pis
ton 5 is in the position shown in Figure 1, pointed
end I6 of pin I4 extends slightly beyond the end 20
of needle ||.
`
Conduit |`| communicates with cylinder 3
through port I8 and with cylinder 5| through
port 56. Plug 8 is annularly recessed at I3 tov N) 5
permit fluid passing through port I8 lto flow free
ly into cylinder 3 at a point slightly beyond the
foremost movement of piston 5 and thus- to ap
ply pressure against face 20 thereof.
Rack 2| is rigidly secured to the outer face of
cylinder 3 and is provided with a series of notches 30'
22 having intervening spaces 23. Handle 24 is
slidably mounted upon cylinder 3 kand rack 2|.
Handle 24 is bored at 25 for the passage of con
duit |'| by which it will be seen handle 24 is free
to move lengthwise of cylinder 3 but is prevented
5
from rotating thereabout.
Cap 26 is secured to handle 24 above rack 2|
by screws 21 and is cut away at 28 and bored at
29 to permit reciprocal movement of dog 30 and
stem 3|, respectively. Dog 30 is provided with 40
notches 32 having intervening spaces 33 to mesh
with comparable spaces 23 and notches 22 on
rack 2|, respectively, and hold handle 24 in a
fixed position on cylinder 3. Dog 3l) is held in
engagement with rack 2| by coil spring 34 inter
posed between it and cap 26. Knob 35 is secured
to rod 3| by rivet 36 for manually raising dog 30
to alter the position of handle 24.
Plate 31, provided with opening 38, is slidably Ul
mounted at right angles to needle || and is rig
idly secured to handle 24 by bolts 39. Cushion 40
of rubber or other resilient material is secured
to face 4| of plate 3`| by screws 42. As handle
24 is moved forward on rack 2|, the extension of
2,110,263
291,
and serves to cut' a neat slit for insertion of the
needle II is relatively diminished, thereby pro
needle into the product. Also, as piston 5 is urged
toward cap 8 due to pressure against face 54,
face 20 simultaneously forces the curing medium
previously contained in the forward end of cyl
viding means for varying the depth of insertion
of needle I I into the product. In practice, needle
II is inserted the full depth permitted by cushion
40, which by reason of its resiliency, will conform
to the contour of the product at the point of in
sertion and act as a sealing means to prevent loss
