APPARATUS FOR TREATING MEAT AND THE LIKE Filed June 22, 1949 2 SHEETS-SHEET 2 Cl, r c G H 1 U ,5 G zz-y ATTORNEYS.
Patented Feb. 26, 1952 APPARATUS FOR TREATING; AN T P E ME T Fred Avery, La Grange, Ap ca iq l Jung 9, a e! n new it has been the usual practice to soak the slabs for a substantial length of time in the curing liquid in order to obtain substantially complete penetration of the liquid throughout tlieslabs. Hams have been cured by injection of curing 'solutions into the veins, but this is notpossible with materials such as bacon because of the fatty character of the slabs and the lack of adequate vein systems. It is also desirable with other types of food materials such as cheeses to distribute curing or treating solutions uniformly through the bodies of the material's.
The present invention, therefore, has for its principal object the provision of a novel'apparatus for distributing by infection a treating or curing liquid substantially uniformly through a body of material to be treated. J
Another object is to provide an apparatus in which a hollow, apertured movably mounted needle is injected into the material, and treating liquid is forced through the needle .into the material in perdetermined volume periunit of travel of the needle. According to one feature of the invention, the solution is forced through the needle by a positive displacement 'pumpumt is operated by a pressure foot engaging the material.
Still another object is to provide an apparatus in which a plurality of needles are movable simultaneously into the material and are individually supplied with treating liquid in proportion to their respective penetrations. Preferably, a positive displacement pump is provided for each needle in order that there is a uniform distribution of the liquid regardless of non-uniformity of the texture of the material, and each pump is operated by a presser foot adjacent its respective needle. A further object is to provide an apparatus of the character under consideration in which a body of material to be treated is advancedfstep by step through the apparatus by reciprocation of a head carrying the needles. In this way liquid is injected into the material at uniformly spaced points throughout its length and width to produce uniform treatment.
The above and other objects and advantages of 1 cl m (or. 99 257) Figure 1 is an elevation of an apparatus embodying the invention with certain parts thereof shownin section; and
ig'ure 21s a' transverse section with parts in elevation.
'Th'eapparatus, as shown, comprises a frame includinga base [0 on which a pair of upright or vertical posts II are supported. A horizontally elongated head I2 is mounted for vertical sliding movement on the posts II and is urged upward thereon by spiral compression spring it around the posts. The head is reciprocated on the frame by'a pair of levers 14 mounted on a horizontal transversely extending shaft I5 and connected by links [6 to the head. The shaft may be oscillated by a handle I! or by any other desired mechanism to move the head downward when desired and to permit it to-raise again under the influence of the springs [3. It together with the handle constitutes driving means for operating the head reciprocating mechanism consisting of the levers I4 and the links l6.
' The'head carries a series of hollow depending needles I8 uniformly spaced along its length and each'of which is formed with one or more laterally facing openings adjacent its tip, as best seenin Figure 2. The upper end of each of the needles is removably attached by a screw thread connection to the lower portion of the head and communicates with a passage l9. The latter is formed in the head, has a check valve 2! in it, and communicates with a vertically extending pump cylinder 22 in the head, there being a separate pump cylinder for each needle. The lower ends of the pump cylinders are supplied with curing liquid from a manifold 23 in individual communication with the cylinders through individual check valves 24, and, as seen in Figure 1, the manifold is supplied with treating or ourns li u d h u a s pp pipe 2 4 piston 26 is reciprocable in each of the cylinders 2.2 and is urged upward by a spring compriession spring 21L As the pistons move downward, they force through the respective needles predetermined quantities of treatingliquid per unit of piston travel. In connection with up ward islidingfmovement 'of the pistons liquid is drawn'into the cylinders after passing the check valves I4.
' In order to operate the pumps, a presser foot 28 is provided adjacent each of the needles. As best seen in Figure 2, each presser foot is mounted for vertical sliding movement with respectto the head by way of a vertically sliding rod and has a central opening therein through Whichthe "associated or corresponding needle may extend to penetrate into the body of material to be treated. Each presser foot is connected through a longitudinally adjustable link 29 to a lever 31 which carries a cam 32 engaging the upper end of the piston 2'6 of the pump that is associated with the same needle as the presser foot. Preferably, the connection between the link 29 and lever 31 is adjustable lengthwise of the lever in order to vary the volume of liquid injected per unit of presser foot movement.
The material to be treated such, for example, as a slab of bacon is supported on a carrier 33 which is horizontally slidable on the frame transversely to the length of the head 12. To advance the carrier the latters edge portions are provided with two similar series of spaced apart notches 34 for engagement by a pair of pawls 35. The pawls, as shown in Figure 2, are formed with elongated slots 36 through which extend pins 37. The latter are carried by arms which are positively connected to, and extend radially from, the shaft [5. As the shaft is rocked counter-clockwise, as seen in Figure 2, the pins 31 will move throughout the length of the slots 36 and will eventually engage the right ends of the slots and shift the pawls 35 to the right. During this movement, the head [2 will move downward carrying with it the presser feet and needles until the presser feet engage the material on the carrier 33. The presser feet are urged downward with respect to the head by means of spiral compression springs 39 which surround the upper ends of the rods on which the presser feet are supported. The lower ends of the springs 39 abut against collars M on the central portions of the rods and the upper ends of the springs engage a crossbar 42 which is carried by the head l2. Thus when the presser feet engage the material to be treated their further downward movement will be stopped and continuing downward movement of the head will force the needles through the presser feet and into the material. As the head moves downward relatively to the presser feet the levers 3| will be rocked to turn the cams 32 and force the pistons 26 downwards into the cylinders 22. It will be noted that with this construction a predetermined quantity of liquid is forced through each of the needles per unit of penetration of the needle into the material so that the liquid is uniformly injected into the material throughout.
its thickness. In the case of materials of varying thickness and varying width such as slabs of bacon, there will, therefore, be discharged into the material a quantity of treating solution which is in direct proportion to the mass of the material and which is distributed throughout the material in proportion to its mass. As shown in Fig. 2 of the drawings the cams 32 are so shaped or contoured that in connection with initial relative movement of the head and presser feet 28 after the presser feet are arrested and the lower ends or tips of the needles initially penetrate the material no downward sliding movement of the pistons 32 into the pump cylinders 22 occurs. After further relative sliding movement of the head and presser feet in connection with further penetration of the needles into the material the cams operate to effect downward sliding movement of the pistons into the cylinders and resultant discharge of the curing or treating liquid into the material. By increasing or decreasing the operative length of the longitudinally adjustable links 29 the time when the needles withdrawn, the head will travel upward a further distance to clear the material, and the presser feet will move upward with it. During this operation the pistons 26 will be moved upwards with respect to the cylinders by the springs 21 and hence will draw in an additional charge of liquid in readiness for the next operation or cycle.
At the same time the levers 33 will move the pins 37 to the left to a sufficient extent to cause the pawls 35 to slide to the left and thereby advance the carrier 33 one step. The amount by which the carrier is advanced is preferably substantially the same as the spacing between the needles so that when a body of material has traveled completely through the apparatus it will have been injected with solution at uniformly spaced points throughout its length and width. I have found, for example, that with bacon the penetration outward from each of the needle punctures is approximately one-half inch so that if the needles are spaced one inch apart and the carrier is advanced one inch at each movement of the head, the bacon will be uniformly treated throughout. With other types of materials the spacing and carrier feed may be varied, as desired. Rocking movement of the handle I! and the shaft l5 may be limited by engagement of arms 43 on the shaft with a fixed stop block 44 on the frame.
