Abstract
Abstract A tubular casing is provided with fluid pressure for shifting an insert back and forth within the casing. The insert is coupled to a carriage which mounts a head moved back and forth between a pickup station and a delivery station in response to movement of the insert. The head pick up work at the pickup station, deposits it at the delivery station and returns to the pickup station to complete one cycle of operation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
141 words
In apparatus for transferring workpieces from a pickup station to a delivery station, the combination comprising A. a tubular casing with longitudinally spaced portions respectively at said pickup and delivery stations, B. a fluid pressure actuated member within said casing shiftable by said fluid pressure back and fort between said stations, C. a carriage on the outer side of said casing provided with rollers, D. a pickup head mounted upon said carriage, E. means paralleling said casing and providing guidance for said rollers and thereby said carriage, and F. means coupling said carriage to said member for movement of said carriage and pickup head back and forth between said stations in response to movement of said member, said pickup head being operable for picking up said workpieces at said pickup station and releasing the same for deposit at said delivery station.
Claim 2
Dependent Claim
141 words
In apparatus for transferring workpieces from a pickup station to a delivery station, the combination comprising A. a tubular casing with longitudinally spaced portions respectively at said pickup and delivery stations, B. a fluid pressure actuated member within said casing shiftable by said fluid pressure back and fort between said stations, C. a carriage on the outer side of said casing provided with rollers, D. a pickup head mounted upon said carriage, E. means paralleling said casing and providing guidance for said rollers and thereby said carriage, and F. means coupling said carriage to said member for movement of said carriage and pickup head back and forth between said stations in response to movement of said member, said pickup head being operable for picking up said workpieces at said pickup station and releasing the same for deposit at said delivery station.
Claim 3
Dependent Claim
30 words
The combination according to claim 1 wherein the casing and fluid actuated member are both cylindrical in transverse section and said fluid actuated member is slidably fitted in said casing.
Claim 4
Dependent Claim
34 words
The combination according to claim 1 wherein the roller and roller guide means are each disposed respectively on opposite sides of the casing and the roller guide means are carried directly by the casing.
Claim 5
Dependent Claim
31 words
The combination according to claim 1 wherein the fluid pressure actuated member and the carriage are interconnected by flexible cable means and thereby coupled together for movement simultaneously in opposite directions.
Claim 6
Dependent Claim
30 words
The combination according to claim 4 wherein the flexible cable means extends from the fluid actuated member in opposite directions through closed opposite ends of the casing to the carriage.
Claim 7
Dependent Claim
37 words
The combination according to claim 5 wherein, after passing through each closed end of the casing, the flexible cable means is trained about antifriction guide means and thereby turned back upon itself for connection to the carriage.
Claim 8
Dependent Claim
57 words
The combination according to claim 1 wherein the casing is made of nonmagnetic material, the carriage is provided with means disposed in close spaced relation to said casing and made of magnetic material, and said fluid actuated member is magnetized thereby to couple said carriage to said fluid actuated member for movement together in the same direction.
Claim 9
Dependent Claim
67 words
The combination according to claim 2 wherein the casing is made of nonmagnetic material, the carriage is provided with means made of magnetic material and provided with substantial surface areas arcuate in transverse section disposed in overlying close spaced relation to said casing, and said fluid actuated member is magnetized thereby to couple said carriage to said fluid actuated member for movement together in the same direction.
Claim 10
Dependent Claim
40 words
The combination according to claim 1 wherein the casing is made of nonmagnetic material, the fluid pressure actuated member is made of magnetic material, the carriage mounts an electromagnet embracing said casing, and means is provided for energizing said electromagnet.
Claim 11
Dependent Claim
40 words
The combination according to claim 9 wherein the means for energizing the electromagnet includes an electric conductor extending along the casing, trolley means mounted upon the carriage and operatively engaging said conductor, and means connecting said trolley with said electromagnet.
Claim 12
Dependent Claim
34 words
The combination according to claim 10 wherein the electric conductor is a rigid member, and the trolley is provided with means engaging said trolley and thereby securing the carriage against turning about the casing.
