Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
Apparatus of modular construction for feeding bar or tube stock of various diameters to a machine comprising, a plurality of feed stations each including a plurality of rollers in contact with the stock, means interlinking the rollers of each feed station for simultaneous movement of all rollers for maintaining a constant definition of a predetermined center line common to all feed stations and to the machine as stock is being fed regardless of stock diameter, means for driving one of the rollers of at least one feed station for imparting a rotary motion to the stock, means for skewing at least one of the rollers of each feed station for imparting translatory motion to the stock, and means for loading consecutive bars of stock into a feed position.
Claim 2
Dependent Claim
128 words
Apparatus of modular construction for feeding bar or tube stock of various diameters to a machine comprising, a plurality of feed stations each including a plurality of rollers in contact with the stock, means interlinking the rollers of each feed station for simultaneous movement of all rollers for maintaining a constant definition of a predetermined center line common to all feed stations and to the machine as stock is being fed regardless of stock diameter, means for driving one of the rollers of at least one feed station for imparting a rotary motion to the stock, means for skewing at least one of the rollers of each feed station for imparting translatory motion to the stock, and means for loading consecutive bars of stock into a feed position.
Claim 3
Dependent Claim
25 words
Apparatus according to claim 1, wherein each feed station includes a trio of rollers disposed at spaced intervals around the stock and in tangency thereto.
Claim 4
Dependent Claim
44 words
Apparatus according to claim 1, wherein the means for driving the rollers of each feed station and said means for skewing the rollers comprise universally coupled shafting, the universally coupled shafting connecting the drivEn rollers providing a common drive shaft for all such rollers.
Claim 5
Dependent Claim
94 words
Apparatus according to claim 1, wherein the means for loading consecutive bars of stock into a feed position comprises a power driven system of links carrying the rollers and a ramp for supporting the bars of stock, one of the links having an interceptor point for holding back all of the bars of stock with the exception of the first bar which rests against an abutment on another of the links, the last named link being movable for releasing said first bar for allowing it to roll into a feed position between the rollers.
Claim 6
Dependent Claim
19 words
Apparatus according to claim 1, including means for adjusting the spacing between the rollers for accommodating various stock sizes.
Claim 7
Dependent Claim
33 words
Apparatus according to claim 4, including means for mechanically interconnecting the rollers, the ramp and the interceptor point, and means for effecting simultaneous adjustment of the rollers, the ramp and the interceptor point.
Claim 8
Dependent Claim
24 words
Apparatus according to claim 6, wherein the means for effecting simultaneous adjustment of the rollers, the ramp and the interceptor point comprises a handwheel.
