Abstract: 582,925. Vehicle spring-suspensions. DYSON, J., POLLARD, T. A., MARENBON. A., BARKER, S., and DYSON & CO., Ltd., R. A. Oct. 6, 1944, No. 19153. [Class 108 (ii)] In a trailer wagon for road vehicles the axle of the rear road wheels is detachably and pivotally mounted for transverse oscillation on an arm 7 of a spring controlled lever 5 pivoted at 6 in the trailer chassis. As shown in Fig. 1, each side member a of the chassis is of hollow section comprising side channels 3 and top and bottom plates 4, and the arm 7 of the lever 5 is tapered to engage within a socket 8 in a housing 9 on a short transverse axle 10 carrying a pair of road wheels .11. To the forward end of the lever 5 is pivoted at 12 one end of a laminated spring 13, the other end of which slidably engages beneath a shoulder 14 on the lever between side cheeks 15. The spring 13 is maintained centrally within the member a by means of wedge blocks 16 engaging between the sides of the spring and inside walls of the member, the wedge blocks being secured and adjusted by bolts 17 passing through slots 17a in the lower plate 4. The socket member 8 is oscillatable on the arm 7 and is held in position thereon by a collar 19 and screw cap 20. In order to load the vehicle the axles 10 are removed from the arms 7 and the chassis lowered as required and after loading the chassis is jacked up and the axles 10 re-engaged with the arms 7, the levers 5 tilting about their pivots 6 to depress the springs 13 against the lower parts of the members a. In a modification, Fig. 6, the inner end of the lever 5 is connected to a plunger 23 in a hydraulic cylinder 22 within the member a, the cylinder being connected by piping 26 with a spring-loaded plunger 27 in a chamber 28 in the member. Alternatively, the springing means may comprise a coiled spring or springs, rubber buffers, or other resilient means.

Title: Improvements in or relating to sewing machines
IPC: D05B73/12
Filed: 1935-07-05
Abstract: 449,054. Sewing machines. HANDSCHUH, A., 103, Urbanstrasse, Berlin. July 5, 1935, No. 19186. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 7, 1936.] [Class 112] A sewing - machine is operated with either the needle and the feeddog co-operating to feed the work, or the feed dog alone. In the latter case the work feed movement of the needle is stopped and the timing of the feeddog movement is delayed until the needle is clear of the work. The work feed movement of the needle is furnished by a lever 20 which is reciprocated by a two-piece shaft 18 and lever 27. The needle movement is stopped by a sliding coupling 22, 23. The timing of the feed dog is changed by uncoupling a loose eccentric 3 from a fixed sleeve 7 and turning the latter with the main shaft through 180‹. In order that the machine may be used for zigzag stitching the direction of vibration of the needle bar is controlled by a guide 33 which encloses the needle bar leaving sufficient clearance for the largest amplitude of vibration. The guide 33 is mounted for vertical displacement in the head of the machine. At the top, the guide is slotted at 34 to receive pins 35 and at the bottom it is slotted at 33 to receive pins 37 on the needle-bar. In the former case the needle-bar is capable of vibration in the direction of the work and in the latter case, in a direction at right angles thereto such as is required for zigzag stitching. In a modification a shaft 39 corresponding to the shaft 18 actuates a lever 45 pivoted at 44. The lower lever-arm 46 is slotted and is connected to a link 47 actuating the needle-bar. A link 50 connects the link 47 and the guide 33. The needle-bar work feed movement is stopped by connecting the end 48 of the lever 47 to the pivot 44 and this movement lifts the guide 33 bringing the slots 34 into engagement with the pins 35. In a further modification the needle bar moves with the feed dog instead of being positively operated. The needle is vibrated laterally by a mainshaft cam-actuated linkage.
