Abstract
Abstract A high speed automatic cold cut feeding, slicing and weighing system which is completely electrical in operation and control to provide cleanliness in operation, high speed, simplified control of all functions of the machine, and extreme accuracy in weight during high speed operation. In the system the rate of feed of the meat feeder is synchronized with the speed of rotation of the slicing blade shaft thereby automatically adjusting the speed of the slicing knife to maintain constant scaling rate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
In a slicing machine having a slicing blade for slicing a loaf of meat product and feeding means for pushing the said loaf to be sliced into the slicing blade the improvement for holding down the loaf of meat and preventing the rotation of such loaf comprising a. a hold down plate positioned adjacent the slicing blade and applying pressure to the top of the loaf; b. a lifter to raise the hold down plate when the slicing operation has been completed and only the butt of the loaf remains; and c. actuator means associated with the feeding means to actuate the said lifter at the conclusion of the slicing operation whereby the hold down plate will be clear of the butt end of the loaf and permit the feeder and butt to move backward.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
243 words
The combination of a. a slicing blade for slicing a loaf of meat product; b. an electric knife motor for rotating the slicing blade, said motor having a device for indicating the speed of rotation; c. a feeder for pushing the said loaf to be sliced into the slicing blade; d. an electric feed motor for driving the feeder, said motor having a device for indicating the speed of rotation; e. stacking and weighing apparatus at the discharge end of said slicing blade for stacking a preselected number of slices of said product as they are discharged by said slicing blade, for weighing the stacks of slices and for conveying the stacks of slices away; f. a knife controller for controlling the rate of speed of said slicing blade and, consequently, the number of stacks per minute; g. a pusher controller for controlling the rate of advance of said feeder toward said slicing blade and, consequently, the slice thickness and weight of a stack of preselected number of slices discharged onto the stacker and weighed; h. a feed back coupling between the knife and pusher controllers and the speed devices on the knife and feed motors whereby variations in the knife speed are automatically introduced into the pusher controller to synchronize the rate of feed of the feeder with the speed of rotation of the slicing blade and maintain a high degree of weight accuracy; and i. a meat hold down device comprising:

Claim 5
Dependent Claim
100 words
a hold down plate positioned adjacent the slicing blade and applying pressure to the top of the loaf to hold such loaf in position and prevent rotation of the loaf; 2. a lifter to raise the hold down plate when the slicing operation has been completed and only the butt end of the loaf remains; and 3. actuation means associated with the feeding means to actuate the said lifter at the conclusion of the slicing operation; whereby the hold down plate will be clear of the butt end of the loaf and permit the feeder and butt to move backward.
Claim 6
Dependent Claim
