Title: Improvements in and relating to sewing machines
IPC: D05B57/02
Filed: 1920-11-16
Abstract: 173,395. Thompson, W. P., (Union Special Machine Co.). Nov. 16,1920. Sewing-machines; feed by devices engaging upper surface of work; presser-bars. - The presser-bar 28 and feed-bar 25 are lifted alternately by a bell-crank lever 60 which pivots alternately upon each of the bars. The feed-bar 25 slides between adjustable plates 40 and its stalk 63 passes through a sleeve 61 pivoted upon the end of the lever 60. A spring 64 between the sleeve 61 and a shoulder on the feed-bar is so proportioned that on the downward movement of the pivot 62 the feed-bar is lowered on to the work, the spring is compressed until its coils are closed and, thereafter, the pivot 62 provides a rigid pivot for the lever 60 in its further oscillation which therefore effects the raising of the presser-bar. In the return movement, after the presser-bar is returned into contact with the work, the feed-bar is not lifted until the movement of the pivot 62 has permitted the spring 64 to expand and the top of the sleeve 61 has contacted with the nuts 66. The to-andfro movement is adjusted by means of a lever 48 having an arcuate slot 57 which is concentric with the pivot 44 when the feed-dog is at the beginning of its stroke. The up-and-down movement is similarly adjustable, the slot being concentric with the pivot 70 of the pitman 71 when the feed-dog is in its lowest position. An arm 78 secured to the presser and a pin 81 on the feed-bar prevent the upper feed-dogs from resting on the lower dog 23 when there is no work in the machine. The upper feed-dog 20 has a single row of serrations and the lower one two rows, one on either side of the upper feed-dog. The presser-bar comprises upper and lower bars 31, 28 which are spaced apart laterally and are connected by clamps upon a member which also carries the pivots of the feed-levers 48, 68 and 60.

Title: Improvements in apparatus for treating textile and like materials
IPC: D06B3/16
Filed: 1959-09-23
Abstract: <PICT:0863773/IV(c)/1> <PICT:0863773/IV(c)/2> Apparatus for treating material in the form of a band with a fluid medium comprises two conveyers between which the material is conveyed through the medium, means for folding material on to one of said conveyers, the two conveyers being separated from one another by a distance which is less than the depth of each fold or plait, whereby the folds or plaits are held together in stack-like formation, such that the direction of travel is first obliquely downwards and then reversed to reverse the sides of the folds before they leave the treating medium and means for drawing off the treated material.  As shown in Fig. 1 two endless conveyers 1, 2 are located in a container of treating fluid.  A band of material 4 is folded by rollers 3 in known manner and proceeds on the conveyer 1 in the direction indicated by arrows. Fig. 1 shows material being folded in the direction of travel and Fig. 2 shows material being folded transverse to the direction of travel. Preferably the distance between the conveyers is less than the fold width or with cross folding the material width so that the folded material is held together stacked between the two bands. Roller 10 may serve as a tension regulating means for conveyer 1. Preferably only one of the conveyers is positively driven, the other being drawn along by the conveyer.  The distance between the conveyers may gradually decrease as they travel through the fluid medium.  Supporting means having a friction reducing surface may be arranged below the conveyer on to which material is folded. The conveyers may be constructed of friction reducing materials e.g. glass fibre fabric.

Abstract: 1453715 Valves for fluid pressure braking systems BENDIX WESTINGHOUSE Ltd 10 July 1974 [11 July 1973] 32958/73 Headings F2V and F2F  A relay valve, e.g. for controlling pressure to a trailer braking system, comprises a housing 1 with a cylindrical bore 2 in which pistons 3, 4, 12 are slidable pistons in response to control pressure supplied to at least one of input ports 13, 14, 15. Piston 4 has an extension 16 carrying a "self-lapping" valve closure member 17 which is biased by spring 18 away from a seat 19. The latter is carried by an exhaust tube 22 which also forms an inlet valve closure member biased against inlet seat 21 by spring 20 to prevent reservoir pressure applied to port 23 from communicating with a work port (not shown) disposed below piston 4 and connected to the trailer brakes. Thus when a control pressure is applied to ports 13, 15 by a foot operated valve or to port 14 by a secondary brake system, piston 4 is forced downwardly so that valve member 17 abuts seat 19 to close the exhaust passage and simultaneously unseat tube 22 to communicate reservoir pressure at port 23 to the trailer brakes via the work port. If the control pressure is reduced, piston 4 rises causing valve member 17 to lift off seat 19 to vent the brake cylinders to atmosphere until a lower pressure is present beneath piston 4, whereupon member 17 again closes the exhaust passage. The pistons 3, 4, 12 move individually or as a stack depending upon which control ports 13, 14, 15 are in use, and mutually guide one another by interfitting skirts 6, 8 provided with nylon packing 11 and seal rings 7, 10.
