Title: Improvements in or relating to a Step-Wise Driving Mechanism
IPC: C03B5/167
Filed: 1968-01-23
Abstract: 1,183,144. Variable speed ratchet gear. SCHUITEMAKER PATENTS S.A. 23 Jan., 1968 [24 Jan., 1967], No. 3522/68. Heading F2D. In a variable ratchet drive, particularly for an unloading conveyer of a motor truck or trailer, wherein a driven member is periodically moved stepwise by way of a one-way clutch and prevented from back-running by a one-way brake, and wherein the non-driving return stroke of the driving member of the clutch is limited by a manually adjustable abutment to vary the driven member stroke, load-variable driven member stroke loss, due to transmission resilience particularly in the clutch and brake parts, is compensated for, and hence driven member stroke (e.g. conveyer feed) for a particular manual setting thereof is rendered substantially uniform irrespective of load, by mounting the reaction member of the one-way brake so as to react against spring means and using the load-variable periodic reaction movement of said reaction member to effect a periodic overriding movement of the adjustable abutment to render the non-driving return stroke of the driving member proportional to the driven member load. The one-way clutch and brake may be linear or, as shown, rotary. As shown, a cam 11 keyed on an input shaft 4 acts on a follower roller 13 rotatably mounted on a spring-returned bell-crank lever 14. The latter, in turn, is connected by parallel links 18 to the driving outer race 22 of a one-way clutch the driven inner race of which is keyed on an output shaft 26. The inner race 24 also forms the rotatable member of a one-way brake having a reaction outer race 27. The one-way clutch and brake have tilting or rolling gripping means 23, 28. The reaction outer race 27 is pivotally connected at 30, 31 to one arm of a three-armed lever 32 having a second arm 34 engaging a stack of Belleville spring washers 36 via a guide pin 35, and a third arm 37 pivoted to a plate 39 guided by a screw-pin and slot 40, 41. The manually adjustable abutment limiting the non-driving return stroke of the follower roller 13 and the driving outer race 22 is provided by an abutment cam 42 adjustably rotatable, via a tube 5 welded thereto, between limits defined by cam edges 43, 44 and the screw-pin 40. The plate 39 surrounds the tube 5 such that on load-variable periodic reaction movement of the reaction outer race 27, the lever 32 and the plate 39, the Belleville washers permitting greater movement with greater reaction load, the tube 5 and hence the abutment cam 42 are moved leftwardly back to increase the non-driving return stroke. The tube 5 may be rotated by a pulling means engaging a wheel of the tube, by a pair of such pulling means oppositely directed for operation from more than one station, or, shown, by a hand wheel (9) adjacent the driver's seat and acting through worm gearing 7, 6.

Abstract: 459,176. Knitting-machines. SNADER, H. B., Temple, Pennsylvania, U.S.A. Feb. 6, 1936, No. 3590. [Class 74 (ii)] In a knitting-machine for full-fashion hosiery including zones comprising courses of covered elastic thread, means are provided for feeding the elastic thread to the needle bar between the desired limits, and adjusting the stitch length at the beginning and end of the elastic courses. A spool 5 carrying the elastic thread is removably mounted, by means of a spring pressed pivot bearing, in a bracket 6 secured to an oscillating bar 1, and is driven by a sleeve 12 on a rotary shaft 4. A reciprocating shaft 13 carries cam plates 14, 15 which, at the limits of its movement in either direction, engage levers 23, 24 to rock the shaft 1 and break the connection between the spool 5 and its driving-means 12. Thread from the spool 5 passes through a tensioning-device including a weight in the form of a ring 28, and then passes to a carrier 26 on a sliding bar 25, which is connected to the shaft 13 by a latch 29 mounted on a sleeve 30 mounted frictionally on the shaft. A handle 32 enables the latch to be lifted to break the connection. To adjust the length of the stitch at the begin ning and end of the elastic courses, the range of oscillation of a shaft 35, Fig. 4, which is connected to the needle bar 36 and is actuated by a cam 34, is varied by means of an eccentric bush 39, Fig. 5, on which the cam roller 33 is mounted. The eccentric bush is operated by a handle 41 and is held in various positions by a ball detent or the equivalent.

Title: Improvements in brake mechanisms
IPC: F16D55/31
Filed: 1940-03-01
Abstract: 539,041. Disc brakes. PRATT, J. H., MANLEY, G. E., and GIRLING,. A. H. G. March 1, 1940, No. 3837. [Class 103 (i)] In a brake, particularly for the landing wheels of aircraft, the web of the wheel is disposed between a pair of brake discs one of which and also the wheel is axially slidable so that by axial movement of the slidable disc the wheel is gripped between the two discs. The slidable disc may be also rotatable and its tendency to rotate when applied to the wheel is then used to give a self-energizing action. The wheel hub 7 is mounted by a pair of roller bearings 8a, 8b on a sleeve 9 bolted to a flange 10a on the fixed axle 10. The outer race members of the bearings with the rollers are slidable on the inner race members and these are slidable on the sleeve 9 and are spaced apart by a spring 11. A normally fixed brake disc 12 is splined on the sleeve 9 and is axially adjustable by nuts 14, 15 on a tubular plug fixed to the axle 10. A second brake disc 18 is slidable on the sleeve 9 and is engaged through a ball-ended strut 26 with a lever 25 fulcrumed on a fixed conical pin 24 and operated by a Bowden cable 28, the casing of which abuts on a fixed arm 23b extending from a plate 23 bolted to the flange 10a. Balls are disposed in conical pits formed in the adjacent surfaces of the lower part of a pair of washers 20, 21 secured respectively to the disc 18 and the flange 10a. Friction linings 7d, 7e are provided on the wheel web 7b. Operation of the lever 25 thus clamps the web 7b between the discs 12, 18 and the tendency of the disc 18 to rotate with the wheel, causes the balls to ride up the conical, pits in the washers 20, 21 thus increasing the brake pressure. The disc 18 is returned by the spring 11 and the lever 25 by a spring 29.
