Abstract: 983,622. Delivering measured quantities of liquid. PAPER CONVERTING MACHINE CO. Inc. Feb. 27, 1961 [Feb. 26, 1960], No. 7091/61. Heading B8N. [Also in Division D1] An apparatus 23 for delivering a predetermined quantity of liquid adhesive under pressure from a nozzle 28 to a moving paper web operates as follows:-adhesive under pressure is delivered from a manifold 25 forming part of a liquid circuit which includes a pump, via passages 43, 41, 40 to a chamber 39 from which it passes via lateral bores 47 and axial bore 48 to the chamber 37 to exert pressure on the diaphragm 61 and so close the passage 75 between the bores 63, 70. Adhesive is prevented from reaching a bore 53 by a floating valve 49 which is forced by the adhesive against a seat 52. On operation of a solenoidoperated valve in the delivery line to the manifold 25 by an automatically operating electric circuit, the adhesive pressure on the valve 49 and on the diaphragm 61 is cut off and air pressure forces the diaphragm 61 to the right, whereby passages 75 and 53 are opened to air and adhesive, respectively. Thus air passes via bores 69, 68, 63, 70 . . . 72 to the nozzle 28 and draws a predetermined quantity of adhesive up the bore 53 for ejection through the nozzle 28, the valve 49 being forced into contact with a seat 48 to cut off the predetermined amount of adhesive in the chamber 37 from the source. A plurality of apparatus 23 may be arranged side-by-side, for applying adhesive periodically to a longitudinally slit moving paper web. Specifications 793,490 and 825,724 are referred to.

Title: Improvements in or relating to automatic clutches
IPC: F16D11/04
Filed: 1940-04-25
Abstract: 540,259. Clutch actuating mechanism. WALTERS, B. April 25, 1940, No. 7425. [Class 80 (ii)] In clutches which dis-engage automatically after one revolution or more, for power presses and the like, a clutch member 19 keyed to the driven shaft 15 is urged by a spring 23 into engagement with a clutch part 18 on a driving pulley 16 free on the shaft 15. The clutch is held dis-engaged by an abutment 24 on a rod 25 connected to the clutch member 19, the rod 25 being slidable in a groove in the shaft 15. The clutch is held dis-engaged by the engagement of the abutment 24 with a stop 26 on a slide 27 acted upon by a spring 29. The clutch is engaged upon depression of a treadle 30, the movement of which is transmitted to the stop 26 through a linkage 31, 33, 34 and catches 37, 38. As the clutch member 19 rotates the abutment 24 engages a cam surface 39 on the link 34 to dis-engage the catches 37, 38. The stop 26 thereupon returns to its operative position. Upon continued rotation of the clutch member 19 the abutment engages a cam 35 fixed to the machine frame and the clutch is thus disengaged. The operative face of the stop 26 is formed as a continuation of the cam 35. When the treadle 30 is released a spring 32 returns the linkage to the operative position, the catches 37, 38 being shaped so as to ride over one another. The clutch may be held permanently out of engagement by inserting a catch 42 between the head of a bolt 41 fixed to the clutch member 19 and a cover 21 fixed to the end of the shaft 15. As shown, the clutch is of the claw type. In order to increase the clearance between the teeth 43, 44, Fig. 6, in the disengaged position each of the torque transmitting faces of the teeth 44 carries a pawl-like member 46. The latter in cross-section is rhomboidal with a cylindrical portion 47 at one corner pivoted in a hole in the teeth 44. The member 46 is acted upon by a spring-pressed plunger 49, so that after dis-engagement of the clutch the edge 50 of the member 46 moves clear of the adjacent edge of the teeth 43.
