Description
A MOUNTING BLOCK
BACKGROUND OF THE INVENTION
The art of simultaneously extruding a meat emulsion material into a casing while also extruding a second material such as chili or cheese into the interior of the casing to ultimately form a frankfurter or the like filled with the interior material is an old art. However, efforts to practice this art onsmodern meat encasing machines. such as that generally shown in United States Patent No. 3,115,668, have not met with the success that is necessary to adapt this process to rapid, mass productlon requirements.
For example, recent efforts to make this adaption of filling the center of a frankfurter or the like with a condiment is illustrated in United States Patents Nos. 4,569,101 and 4,570,298. However, it is believed that the concept of these patents interferes with the free flow of the material being used and this results in damage to the material being utilized.
Also, the devices of these patents and others are complex in construction, less sturdy than ie desired for mass production requirements, and more difficult to clean.
In addition, difficulty exists with prior art devices insofar as controlling the coordinated rate of extruding two materials simultaneously into the casing material.
Therefore, it is an object of this invention to provide a compound pump mechanism for meat encasing machines and the like whereby dual pumps are used for the dual extrusion process and wherein the pumping operations of the two pumps can be carefully coordinated and controlled.
A further object of this invention is to provide a compound pump mechanism for meat encasing machines and the like wherein two pumps are provided with a single source of operational power.
A still further object of this invention is to provide a compound pump mechanism, wherein the pumping capacity of one pump can be selectively adjusted with respect to the other pump.
A still further object of this invention is to provide a compound pump mechanism wherein two pumps are powered by the same common drive shaft with the pump capacity of one pump being selectively adjustable with respect to the other pump, and wherein the speed of operation of the common drive shaft will maintain the proprtionate pumping capacities of both pumps.
A still further object of this invention is to provide a compound pump mechanism, wherein dual pumps can deliver material being pumped to the ends of concentrically positioned inner and outer stuffing horns without damaging the pumped material.
A still further object of this invention is to provide a compound pump mechanism, wherein the entire apparatus can be easily cleaned and wherein the pumping structure and the means for supplying the pumped material to the ends of the concentrically arranged stuffing horns are simple of manufacture, and structurally sound.
These and other objects will be apparent to those skilled in the art.
SUMMARY OF THE INVENTION.
A compound pump mechanism is provided adjacent the inlet ends of concentrically positioned inner and outer stuffing horns or tubes of a meat encasing machine. The first pump mechanism is in communication with a source of conventional meat emulsion, and is powered by a vertically disposed power shaft. This power shaft extends into the hous ing of a second pump mounted adjacent to, and preferably oh top of, the first pump housing. The drive shaft of the first pump housing operates the pump mechanism in the second pump housing.
Both pumps have inlet and outlet ports for conveying material to be pumped. The outlet ports of both pumps discharge the pumped material into a block element which sl id- ably receives the ends of two concentrically positioned inner and outer stuffing horns. The pumped material from the second pump housing delivers pumped material into the end of the inner stuffing horn, and the pumped material from the first pump delivers-meat emulsion or the like into the end of the outer stuffing horn.
The housing of the upper pump or second pump contains a vane-type pumping mechanism. The pumping capacity of that pumping mechanism is selectively controlled by pivot ing the position of the second pump housing with respect to the first pump housing.

DESCRIPTION OF THE PREFERRED EMBODIMENT.
The numeral 10 designates a conventional sausage encasing machine, the major components of which are essentially shown in United States Patent No. 3,115,668. These machines typically are comprised of a frame 12 and a plurality of legs 14. A pump assembly 16 is secured to the upper portion of frame 12 and is powered by a power mechanism (not shown) normally mounted within the frame. A stuffing horn assembly 16 is operatively reciprocally connected to the pump assembly.
A chuck assembly 20 supports the outer end of stuffing horn assembly 18 and normally provides rotational motion to a casing mounted on a stuffing horn which extends into the chuck assembly.
A conventional linking mechanism 21 is located downstream from the chuck assembly 20. A discharge horn 22 is mounted downstream from the linking mechanism to receive the linked sausages or frankfurters. A conventional conveyor 24 is positioned downstream from the discharge horn and is adapted to receive the linked product from the discharge horn. All of these foregoing components are typically present in modern meat encasing machines, and do not of themselves constitute the essence of the present invention.
A lower pump 25 includes a lower pump housing 26 which is secured in any convenient fashion to the top of frame 12. Lower pump housing 26 has an outlet port 28 shown in dotted lines in Fig. 3. This pump housing also has an inlet port connected to a source of meat emulsion or the like1 neither of which are shown.
Pump 25 is a conventional gear-type metering pump which include gears 30 which are rotatably powered by a shaft 32. Lower pump housing 26 can have a detachable cover 33 which is secured in place by any convenient means.
Upper pump 34 includes upper pump housing 36 which has a circular well 38 formed in its lower central portion. A center bore 40 is formed in the upper portion of well 38.
The upper splined end portion 42 of shaft 32 extends upwardly through well 38 and terminates within center bore 40.
The pumping mechanism for pump 34 includes a cylindrical hub 44 which has a plurality of vanes 46 radially slidably mounted in radially disposed slots (not shown) in hub 44.
Wells 48 are formed in the upper and lower surfaces of hub 44 and movably receive cylindrical rings 50 which are spaced from the spline portion 42 of shaft 32. The outer surfaces of the rings 50 engage the inner lower portions of each of the vanes 46.
Two bolts 52 extend through arcuate slots 54 which vertically extend through the upper pump housing 36 and are threadably secured in cover 33. This housing is pivotally secured to the lower pump housing 26 by means of bolt 56 which is threadably secured in cover 33.
As shown by dotted lines in Figs. 4 and 5, the upper pump 34 includes an intake port 58 which is in communication with an intake fitting 60, and this housing also has an outlet port 62 which is adapted to be connected to discharge'material conduit 64 (See Fig. 2).
Upper pump 34 is a conventional vane-type pump. Its pumping capacity can be varied by pivoting the pump housing 36 in a horizontal plane with respect to the lower pump housing 26. This is accomplished merely by loosening the bolts 52 and 56. Fig. 5 illustrates a position of zero pumping capacity for tlxe upper pump 34. When in this position, the rings 50 and vanes 46 are concentrically and symetrically positioned around the vertical axis of shaft 32. Fig. 4 shows that the upper pump housing 36 has been rotated in a slight counterclockwise direction with respect to the lower pump housing 26. Fig. 4 shows the upper pump in a position of maximum pumping capacity.
Again, the structure of the upper pump 34 is conventional, and does not of itself comprise the essence of this invention.
As shown in Figs 2, 4, and 5, a mounting block 66 is secured in any convenient fashion to one side of the lower pump housing 26 of lower pump 25. The mounting block 66 has a first inlet port 68 which is in communication with an interior material compartment 69 (Fig. 7). A second inlet port 70 is in communication with the discharge port 28 of lower pump housing 26. The inlet port 70 terminates in an interior material compartment 72.
An elongated longitudinal bore 74 extends through mounting block 66 as shown in Fig. 7. The bore 74 extends through both of the material compartments 69 and 72. Appropriate annular grooves are formed around bore 74 at opposite sides of compartment 69 and adjacent the compartment 72 to receive sealing rings 76.
A cylindrical plug 78 is.slidably mounted within bore 74. Plug 78 includes aperture 80 which extends completely therethrough and which is adapted to be in communication with material compartment 69 during the pumping operation.
An elongated bore 62 (Fig. 7) is formed in the inner end of plug 78 and is in communication with aperture 80.
An inner horn 64 of smaller diameter is rigidly secured by any convenient means in the outer end of bore 82 (Fig. 7). A larger diameter outer horn 86 has one of its ends extending into and through the portion of bore 74 adjacent material compartment 72, and the end thereof is in communication with the compartment 72. A pair of elongated longitudinal tabs 88 extend longitudinally from the end of the outer horn 86, through compartment 72, and are received in slots 90 of plug 78. The ends of the tabs 88 are soldered or otherwise secured within slots 90.
Outer horn 86 (sometimes referred to as a stuffing tube or stuffing horn) is of conventional construction except for the tabs 68. It conventionally slidably extends from the pump to the chuck assembly 20. It can be slidably retracted from the chuck assembly to receive a shirred casing 92 which is mounted on the outside surface of horn 86 and abuts follower or keeper element 94. The inner horn 84 is concentrically mounted within outer horn 86. As shown in Fig. 2, the outer end of horn 84 may protrude slightly beyond the outer end of horn 86, although this arrangement is not absolutely necessary in the dual extrusion process.
An indicia mark 94 (Fig. 2) can be placed on the outside of upper pump housing 36. As explained hereafter, indicia mark 94 can be aligned with any one of a plurality of indicia marks 96 (Fig. 4) located on the top of cover 33 of the lower pump housing 26.
In operation, the position of the upper pump housing 36 can be adjusted to the desired position in the manner described heretofore to adjust the pumping capacity of the upper pump 34. Indicia marks 94 and 96 can be used to assist the operator in securing the upper pump housing 36 in a given desired position. The power plant of the machine 20 is then started by conventional means to cause shaft 32 to rotate. This causes the pumping mechanism of both pumps 25 and 34 to commence. Typically, a quantity of cheese, ch:li, or ocher condiment is operatively connected to the inlet port 58 of the upper pump to assist the operator in securing the upper pump housing 36 in a given desired position. The power plant of the machine 20 is then started by conventional means to cause shaft 32 to rotate.This causes the pumping mechanism of both pumps 25 and 34 to commence. Typically, a quantity of cheese, chili, or other condiment is operatively connected to the inlet port 58 of the upper pump 34. Similarly, a conventional supply of meat emulsion is made available to the inlet port of the lower pump 25.
The operation of the two pumps causes meat emulsion to flow into material compartment 72 of mounting block 66, and thence into the end of outer horn 86. Little if any interference in this flow is provided by the tabs 88 which extend atross the material compartment 72.
At the same time, condiment material is being pumped from the upper pump 34 through conduit 64 and into inlet port 68 of mounting block 66. This material flows into aperture 80, thence into longitudinal bore 82, and thence into the end of inner horn 84.
The flow of meat emulsion into outer horn 86 is generally shown by the arrows 98 in Fig. 6. Similarly, the flow of condiment material into the end of inner horn 84 is generally shown by the arrows 100 in Fig. 6.
Since the two pumps 25 and 34 are powered by the same shaft 32, their pumping action is always precisely coordinated. By being able to adjust the pumping capacity of the upper pump 34, the flow of condiment material can be also carefully controlled. Once the pumping capacity of the upper pump 34 is adjusted to the desired flow, the pumping capacity of the two pumps will always remain precisely coordinated even though the rotational speed of shaft 32 is varied.
The pumped material of this invention is adapted to have substantially free flowing characteristics so that the material is not damaged while en route. The structure of this invention is simple, strong, and is easily cleaned. Accordingly, it is seen that this invention accomplishes at least its stated objectives.
