Abstract
Abstract An injecting apparatus and method for injecting a liquid additive at high pressure into an object having converging opposite ends, such as a fowl, in which there is a table upon which the object is placed, a set of nozzles for engaging one end portion of the object, a clamping member for engaging and partially surrounding the opposite end portion, and means for clamping the object between the nozzles and the clamping member while the fluid liquid additive is being injected. The nozzles are formed in two groups which vary in length and disposition with respect to each other in such a manner that their terminal portions approximately conform with the surface of the object to be injected, such as the breast of a fowl. The passages through the nozzles also vary in size so that a greater amount of liquid is introduced into certain portions of the object requiring more liquid additive, such as the breast portion of a fowl. The table is vertically adjustable to enable proper positioning of the object to be injected with respect to the nozzles. The means for injecting the liquid includes a piston and cylinder and there is means for adjusting the stroke of the piston and hence the amount of liquid additive which is injected. In injecting the liquid into a yieldable object such as a fowl, the fowl is compressed during the injecting operation to prevent escape of the liquid additive, and after the injecting operation is completed, is released to assume its normal shape.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
143 words
Apparatus for injecting a fluid additive into the flesh of a fowl to improve the eating qualities thereof, said apparatus comprising: a table for supporting the fowl, a plurality of nozzles supported with respect to said table disposed so as to engage the breast of a fowl placed on the support on opposite sides of the longitudinal center of the fowl. fluid delivery means for delivering to said nozzles a fluid additive under sufficiently high pressure that said fluid additive penetrates the skin of a fowl engaging said nozzles without substantial rupture of said skin, a posterior engaging member also supported with respect to said table and designed to engage and partially surround the posterior portion of a fowl, and means for causing relative movement of said nozzles and said posterior engaging member to clamp a fowl on said table against said nozzles.
Claim 2
Dependent Claim
143 words
Apparatus for injecting a fluid additive into the flesh of a fowl to improve the eating qualities thereof, said apparatus comprising: a table for supporting the fowl, a plurality of nozzles supported with respect to said table disposed so as to engage the breast of a fowl placed on the support on opposite sides of the longitudinal center of the fowl. fluid delivery means for delivering to said nozzles a fluid additive under sufficiently high pressure that said fluid additive penetrates the skin of a fowl engaging said nozzles without substantial rupture of said skin, a posterior engaging member also supported with respect to said table and designed to engage and partially surround the posterior portion of a fowl, and means for causing relative movement of said nozzles and said posterior engaging member to clamp a fowl on said table against said nozzles.
Claim 3
Dependent Claim
70 words
The apparatus of claim 1 in which the nozzles are fixedly secured with respect to said table, in which said posterior engaging member is movable with respect to said table to act as a clamping member, and in which said means for causing relative movement of said nozzles and said posterior engaging portion is a means for moving said posterior engaging member towards said nozzles to clamp the fowl therebetween.
Claim 4
Dependent Claim
55 words
The apparatus of claim 1 in which the table and nozzles are relatively adjustable in a vertical direction to accommodate the apparatus for fowl of various weights and to insure correct positioning of said nozzles with respect to the breast of the fowl despite such variations in weight and hence of size of the fowl.
Claim 5
Dependent Claim
31 words
The apparatus of claim 3 in which the nozzles are fixed in a vertical direction and the table is vertically adjustable with respect to the nozzles and the posterior engaging member.
Claim 6
Dependent Claim
43 words
The apparatus of claim 1 in which said fluid delivery means includes a piston and a cylinder in fluid communication with said nozzles, and means for adjusting the stroke of the piston and hence the amount of fluid additive introduced into the fowl.
Claim 7
Dependent Claim
32 words
The apparatus of claim 1 in which the table has guide means to engage the fowl to maintain the longitudinal axis of the fowl parallel to the longitudinal axis of the table.
Claim 8
Dependent Claim
40 words
The apparatus of claim 1 in which said plurality of nozzles comprises two groups of nozzles varying in length and disposition with respect to each other so that their terminal portions approximately conform with the breast of a typical fowl.
Claim 9
Dependent Claim
61 words
The apparatus of claim 7 in which the passages through the nozzles adjacent the portions of the fowl having the larger amounts of flesh to be injected are larger than those through other of the nozzles so that a greater amount of fluid additive is introduced into the portions of the fowl having the greater amount of flesh to be injected.
Claim 10
Dependent Claim
138 words
Apparatus for injecting a fluid into an object having opposite end portions each converging towards its outer end, said apparatus comprising: a table for supporting the object to be injected, a nozzle assembly supported with respect to said table and comprising a housing and a plurality of nozzles projecting from said housing and extending outwardly to varying extents to conform with a portion of the surface of one end portion of such an object, means for delivering to said nozzles a fluid additive under high pressure for injection into such an object, a member also supported with respect to said table and designed to engage and partially surround the opposite end of such an object, and means for causing relative movement of said nozzle assembly and said last named member to clamp such an object against the nozzles.
Claim 11
Dependent Claim
138 words
Apparatus for injecting a fluid into an object having opposite end portions each converging towards its outer end, said apparatus comprising: a table for supporting the object to be injected, a nozzle assembly supported with respect to said table and comprising a housing and a plurality of nozzles projecting from said housing and extending outwardly to varying extents to conform with a portion of the surface of one end portion of such an object, means for delivering to said nozzles a fluid additive under high pressure for injection into such an object, a member also supported with respect to said table and designed to engage and partially surround the opposite end of such an object, and means for causing relative movement of said nozzle assembly and said last named member to clamp such an object against the nozzles.
Claim 12
Dependent Claim
43 words
The apparatus of claim 9 in which the table and nozzles are relatively adjustable in a vertical direction so as to insure that the nozzles are properly positioned with respect to the object being injected, despite different sizes of the objects being injected.
Claim 13
Dependent Claim
56 words
The apparatus of claim 1 in which the means for causing relative movement of said nozzles and said posterior engaging member is capable of sufficient clamping force upon the fowl that said nozzles all firmly engage the breast of the fowl and that the fowl is compressed to prevent the escape of the injected fluid additive.
Claim 14
Dependent Claim
45 words
The apparatus of claim 11 in which said means for causing relative movement oF said nozzles and said posterior member is quickly releasable to enable the fowl to quickly return to its original shape following the injecting operation to prevent escape of the fluid additive.
