Abstract
Abstract Apparatus is shown for injecting a material into a poultry product whereby the injection needles may be provided at a location remote from the pump and shut-off valve controlling the flow of material to the injecting apparatus. The injection apparatus consists of a needle assembly having the needles provided at a predetermined angle to the handle on the needle assembly such that when the operator holds the injection apparatus in the normal position, the needles are positioned to prevent the injection material from leaking or dripping therefrom. Further, since there is substantially no leakage of injection material from the needles, it is possible to inject birds with a desired quantity of fluid within very low tolerances.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
225 words
Apparatus for injecting a basting material into the flesh of poultry substantially without leakage of the basting material comprising: a pump connected to a source of basting material, a control valve connected to said pump for controlling the flow of basting material to be injected, a needle assembly for injecting the basting material into the poultry product, a flexible hose connecting said control valve into said needle assembly, said hose having a sufficiently low coefficient of expansion to substantially prevent the build-up of residual pressure in the hose, said needle assembly including a handle member and at least one injection needle having injection openings therein, said handle member being at a predetermined angle of about 30* - 60* to said needle such that when the operator holds the needle assembly with the needle in a horizontal position sufficient leverage for effecting the ready insertion and removal of the needle from the poultry product being injected is obtained from said hAndle member and when the operator holds the needle assembly in an at-rest position the needle is inclined, the injection openings in said needle being sufficiently small that the surface tension of the material within the needle in combination with the prevention of build-up of residual pressure in the hose substantially prevents the basting material from leaking from the injection openings when the needle is inclined.
Claim 2
Dependent Claim
225 words
Apparatus for injecting a basting material into the flesh of poultry substantially without leakage of the basting material comprising: a pump connected to a source of basting material, a control valve connected to said pump for controlling the flow of basting material to be injected, a needle assembly for injecting the basting material into the poultry product, a flexible hose connecting said control valve into said needle assembly, said hose having a sufficiently low coefficient of expansion to substantially prevent the build-up of residual pressure in the hose, said needle assembly including a handle member and at least one injection needle having injection openings therein, said handle member being at a predetermined angle of about 30* - 60* to said needle such that when the operator holds the needle assembly with the needle in a horizontal position sufficient leverage for effecting the ready insertion and removal of the needle from the poultry product being injected is obtained from said hAndle member and when the operator holds the needle assembly in an at-rest position the needle is inclined, the injection openings in said needle being sufficiently small that the surface tension of the material within the needle in combination with the prevention of build-up of residual pressure in the hose substantially prevents the basting material from leaking from the injection openings when the needle is inclined.
Claim 3
Dependent Claim
11 words
The apparatus according to claim 1 wherein the angle is 45*.
Claim 4
Dependent Claim
13 words
The apparatus according to claim 1 wherein the needle assembly has two needles.
Claim 5
Dependent Claim
186 words
Apparatus for injecting a material into a poultry product substantially without leakage of the material wherein the needle assembly is located at a position remote from the pump and control valve assembly which supplies the injection material from a source to the needle assembly comprising: a flexible hose connecting the pump and control valve to the needle assembly, said hose having a sufficiently low coefficient of expansion to substantially prevent the build-up of pressure in the hose, said needle assembly consisting of a manifold member, at least one hollow needle connected to said manifold, said needle having injection openings therein, and a handle member connected to said manifold at a predetermined angle to said needles such that when the operator holds the needle assembly in an at-rest position the needles are inclined to the hose connected thereto and the injection openings in said needle being sufficiently small that the surface tension of the material within the needle in combination with the prevention of build-up of residual pressure in the hose substantially prevents the basting material from leaking from the injection openings when the needle is inclined.
Claim 6
Dependent Claim
186 words
Apparatus for injecting a material into a poultry product substantially without leakage of the material wherein the needle assembly is located at a position remote from the pump and control valve assembly which supplies the injection material from a source to the needle assembly comprising: a flexible hose connecting the pump and control valve to the needle assembly, said hose having a sufficiently low coefficient of expansion to substantially prevent the build-up of pressure in the hose, said needle assembly consisting of a manifold member, at least one hollow needle connected to said manifold, said needle having injection openings therein, and a handle member connected to said manifold at a predetermined angle to said needles such that when the operator holds the needle assembly in an at-rest position the needles are inclined to the hose connected thereto and the injection openings in said needle being sufficiently small that the surface tension of the material within the needle in combination with the prevention of build-up of residual pressure in the hose substantially prevents the basting material from leaking from the injection openings when the needle is inclined.
Claim 7
Dependent Claim
67 words
The apparatus according to claim 4 wherein said handle member comprises a rigid supply line portion connected to said hose and to said manifold at the predetermined angle and a hand hold member connected to said supply line portion at substantially a right angle thereto such that when the operator holds the injecting apparatus in the at-rest position the needle is inclined to the supply line portion.
Claim 8
Dependent Claim
29 words
The apparatus according to claim 5 wherein two needles are provided on the manifold and the needles are provided at an angle of about 30*-60* from said handle member.
