Title: Apparatus for supplying lubricant to chain links
IPC: B65G45/08
Filed: 1969-07-25
Abstract: 1,272,967. Lubricating. TOKYO SHIBAURA DENKI K.K. 25 July, 1969 [30 July, 1968 (2)], No. 37514/69. Heading F2A. An automatic lubricator for chain links has a rotary member 9 whose rotation is synchronized with the movement of the chain links, with a lubricant supply head 13 mounted on the member 9 and a valve which actuates the head to forcibly lubricate the links. The rotary member 9 is journalled by a shaft 7 in a support 6 and consists of upper and lower sprockets which engage rollers 11a and 11b of the chain links 11. The links are also guided by rollers 11c, lid and 11e which contact the supporting frame 6. Each link is provided with a lubricant port 12 from which lubricant is fed to each joint of the link. Mounted on the rotary member 9 is a lubricant supply head 13 having a closed cylinder 40 at one end of which is a compressed air opening, to which air may be supplied via a flexible pipe 33 from the shaft 7. Lubricant is also conveyed from the shaft to the head by means of a flexible pipe 24. Compressed air is fed via a passage 28 to the disc 25 in which there is provided an arcuate groove 26. The disc 25 engages a plate 30 which rotates with the shaft 7 and which has a number of air ducts 31, one for each lubricant supply head, which communicate with the head via passages 32a, 32b and 33. The arcuate groove 26 is arranged to engage each duct 31 periodically as the shaft rotates so as to operate each lubricant head in turn. The ducts are exhausted by means of a second groove (27) (Fig. 4, not shown) which communicates with an exhaust passage 29. In operation air is supplied to the passage 15 which causes the piston 17 to move against the spring 16 and forces the nozzle 14 outwards to engage the lubricant port 12 of a link 11. The port 12 causes the valve 14a to be released, lubricant being forced from the chamber 19 through the check valves 20a and 20b to the link. As the member 9 rotates, the compressed air supply to the head is cut off and the air exhausted, causing the piston 17 to return to its original position and the valves 14a, 20a and 20b to close.

Filed: 1974-08-28
Abstract: 1480505 Bookbinding XEROX CORP 28 Aug 1974 [29 Aug 1973 (2)] 37601/74 Heading B6A In bookbinding apparatus of the kind in which a binding strip 16, Fig. 2, is applied to a stack of pages 22, means are provided for producing a binding strip of the correct length, in accordance with a manually adjustable wheel 100, Fig. 5, and for pushing the strip into a binding position. The stack is located between guides 20, held by clamps 28, moved down past a retractable stop 40 into contact with the strip 16 resting on top of heated platens 36, then raised and lowered again so that the strip is pressed downwardly onto a heated platen 38. Platens 36 then clamp the strip 16 onto the outermost page sides. The strip comprises a paper or fabric substrate having a thin, high tack adhesive underneath a thick, low tack adhesive, and is fed by pinch rollers 70, 72 from a cassette 14, Fig. 4, the roller 72 being driven via a shaft 98 and drive gear 94. The gear 94 carries a detent 92 which is engaged by a biased driving lever 90 attached to a rotating shaft 88. The adjustable wheel 100 carries a stop 104 and when a pin 106 on the gear 94 engages this stop, gear 94 is stopped, and the bias on lever 90 is overcome so that it can move past the detent 92. Thus drive to the feed roller 72 is stopped. The length of the incremented feed feed steps imparted in this way to the binding strip, is determined by the angular position of the stop 104 on wheel 100. Once feeding has stopped and the strip is cut by a guillotine cutter 114 pin 106 is rotated back to its starting position by a torsion spring 110. The cut strip is then moved into the binding position in guides 42, 44 by a pivotable pusher finger 124. Before binding, the thickness of the stack is gauged by manually rotating a knob 45 which causes the guides 20 clamps 28 and guides 42, 44 to approach and caliper the pages. The knob is then turned back a pre-determined amount to correctly space the guides 42, 44. If a cassette holding binding strip of the incorrect width is then inserted into the apparatus switch devices cause a warning light to show.

A machine for continuously winding wire comprises a rotatable disc 43 carrying at least two winding reels 54, 55 and independent drive motors 62, 63 for the reels, the arrangement being such that when a reel 54 is full the disc 43 is rotated through half a revolution to bring the wound reel 54 from an upper winding station to a lower unloading station, this movement causing the empty reel 55 to act temporarily as a guide for the wire 1 as it continues to pass on to the lower reel 54. The wire is fed by a capstan 2 to a wire accummulator 14, 16 and thence to a wire traversing arm 19. The accummulator includes a pivoted arm 17, and movement of this arm in response to any difference in speed between the capstan 2 and the empty take-up reel 55 is used to adjust the speed of the motor driving the empty take-up reel such that it rotates at the same take-up speed as the speed of the wire supplied by the capstan 2. When the lower reel 54 is fully wound, as determined by a measuring meter, an arm 68 engages the wire extending between the reels 54, 55 and forces it to a setting where it is caught by a clamping device 74 on an end cheek 72 associated with the reel 55 and presses the wire leading to the reel 54 against the disc 43. The wire then breaks between the reels 54, 55. The wire is traversed onto the reel at the winding station by the guide arm 19 being reciprocated by a screw and nut means 20, 23 Fig. 2 (not shown), the direction of rotation of the screw being determined through the medium of two clutches that are alternately made effective. The shafts 52, 53 on which the reels 54. 55 are mounted carry cheeks 71, 72 having dogs that engage the reels 54, 55 to drive them, and clamping devices 74 for catching the wire. The shafts have locking means at their extremities for holding the reels 54, 55 thereon.
