Filed: 1961-09-29
Abstract: 931,536. Fluid pressure apparatus. CLEMCO AERO PRODUCTS Inc. Sept. 29, 1961, No. 35337/61. Class 69 (2). A fluid pressure device comprises a piston 12, Fig. 1, and rod 11 forming an assembly reciprocatable in a cylinder 10, latching means 26 for interengaging the cylinder and assembly, means 30 mounted on the assembly for locking the latching means in interengagement with the cylinder and assembly, and means for moving the locking means to release the latching means. Each end of the cylinder is provided with a ring 26, 27 of latching fingers which co-operate with shoulders 22, 23 on the piston when the latter is in one or other of its end positions. Locking collars 30, 31 interconnected by bolts 34, which are slidable in bores in the piston and screwthreaded into a cap 36, engage their associated rings of fingers where the piston is in one or other of its end positions. Fluid pressure can be supplied through either port 13 or port 14 to move the piston in opposite directions. When supplied through port 14, the piston moves to the left until the shoulder 22 moves the fingers 26 inwardly to engage the collar 30 which moves relatively to the piston against springs 32. Further movement of the piston permits the fingers to spring outwardly behind the shoulder 22 and the springs 32 move the collar into the ring of fingers to retain them in position. When the piston is moved to the right, fluid pressure from port 13 passes through ports 38 and the spaces between the fingers to act on the end of the cap 36 which moves to disengage the collar 30 from the fingers 26 to enable the fluid pressure to move the piston the fingers riding over the shoulder 22. The piston is locked at the other end of its stroke by the fingers 25 engaging the shoulder 23. The locking collar 31 retains the fingers in engagement with the shoulder until fluid pressure from the port 14 acts on the heads of the bolts 34 and, through passages 39, 40 in the rod, on the inside of the cap 36 to move the collar from engagement with the fingers. The length of the rod 11 can be adjusted by a screw connection 41 and a screw-threaded end cap 43 carrying the fingers 27 can be adjusted to vary the stroke of the piston. In another embodiment, the cap 36 is replaced by nuts on the bolts 34 and fluid pressure acts on the heads of the bolts or on the nuts to move the locking collars from engagement with the fingers. In a further embodiment, the piston 58, Fig. 7, is axially slidable between collars 56, 57 on the rod 51, the collars co-operating with fingers 54, 56 at the ends of the cylinder 50 to lock the rod in its end positions. Springs 64, 65 act to urge rings 62, 63 into engagement with the fingers to maintain them latched behind the collars when the rod is in its end positions and are moved from engagement with the fingers by fluid pressure when the rod is to be moved. A lamp 76 or 77 is lit to indicate when the rod is locked in one or other of its end positions by abutment of the rings 62, 63 with levers 70, 71 operating switches 75.

Abstract: 863,631. Sealing packages with adhesive tape. ADHESIVE TAPES Ltd. Nov. 6, 1959 [Nov. 6, 1958], No. 35636/58. Class 73. A V-sealer which applies pressure-sensitive adhesive tape to the retreating face of a carton has a presser 19 on a slidably-mounted arm 18 pivotally connected (at 22) to a retractable tape-applying member 3. The member 3 is carried on a bell-crank lever 4 pivoted to a side frame plate 5 at 6 and 15 is spring biased at 7. The arm 18 has a groove 21 in which slides a stud 20 fixed on the frame 5. Tape 13 from a roll 11 is led to the member 3 and is retained there by a finger 9 carried on a pivoted arm 8. A roller 24 on a flexible wire 25 gives additional support to the tape when the finger 9 is disengaged. A package 2 moving along the pathway 1 presses back the projecting finger of the arm 8 and contacts the leading end of the tape on the member 3. The member 3 is thereby tilted together with the lever 4 and wipes the tape along the underside of the package. This movement of the lever 4 draws down the arm 18 so that the presser 19 is also under the package. The package then cocks against a spring 18a a pivoted arm 16 which carries a knife 17. Release of the arm 16 at the rear edge of the package allows the knife 17 to rise and cut the tape leaving the leading end of the main tape supply lying along the member 3 ready for the next cycle. The presser 19 then rolls over the rear edge and up the retreating face of the packet to wipe on the severed end of the applied strip. In an alternative embodiment (Fig. 4, not shown) the tape is retained on the member 3 by a withdrawable spike instead of by the finger 9 and the arm 18 slides through a pivoted roller slideway fixed to the plate 5 instead of on a pin 20.
