Abstract
Abstract A fluid-operated apparatus for injecting seasoning solutions into meat having a reciprocable head with spaced, independently force-limited needle elements disposed over a conveyor belt for injecting the meat as it is successively positioned by longitudinal and lateral movement of the conveyor belt. The needle elements have individual poppet valves actuated by needle penetration into the meat. The needles are pushed back into the head when bone or cartilage is encountered and a predetermined force is exceeded, thereby protecting them from damage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
An injection system for injecting seasoning solutions into meat comprising manifold means for coupling to a source of seasoning solution, a plurality of hollow needles depending from said manifold means for injecting seasoning solutions into the meat, means including a plurality of telescoping tubes coupling said needles to said manifold means for independent, force-limited insertion into the meat, said coupling means further including a valve sleeve surrounding the upper end of each of said hollow needles, valve seat means mounted within said valve sleeve, cap means sealing the upper end of each needle, said cap means being mounted for limited movement within said valve sleeve and being dimensioned to allow the passage of solution therearound, and valve seal means mounted in said cap means for forming a seal with said valve seat means to prevent the passage of solution through said hollow needles until said needles are moved upwardly.

Claim 3
Dependent Claim
18 words
The combination according to claim 1 comprising upper needle guide means to provide moment-resisting support for the needles.
Claim 4
Dependent Claim
36 words
The combination according to claim 1 comprising lower needle guide means which engaged the meat to be injected to provide moment-resisting support for the needles and hold the Meat in position when the needles are withdrawn.
