Title: Improvements in and relating to jacking-apparatus for motor cars or other vehicles
IPC: B60S9/10
Filed: 1930-02-14
Abstract: 348,688. Fluidpressure operated jacks. HEDGES, A. E., Kingston, Taunton, Somerset. Feb. 14, 1930, No. 5024. [Class 78 (iii).] A jacking attachment for motor and other vehicles comprises a pivoted link or strut 6 the free end of which is connected to the rod 20 of a piston 21 operated by fluid pressure in a pivoted cylinder 17. The ends of the piston rod and link are forked and connected by a pin 8 carrying a roller 9 which may engage the ground directly or may be peripherally grooved to ride along a cam track 10 on a shoe 11 suspended by means of shaped bars 12 passing over the ends of the pin 8 and constrained by a compression spring 19 on a rod 14 connecting the end 15 of the shoe to a bracket 16 on the cylinder. The piston stroke is limited by a rod 22, passing through the end of the cylinder, where it is screwed into a part 24a forming the pivotal connection to the supporting bracket 25 on the vehicle. Fluid under pressure, supplied by a pump and controlled by a two-way cock, is conveyed to the inner end of the cylinder by a connection 44 or may be led to the outer end from a second connection 46 through a pipe 47 leading to an elbow 48. Non-return valves may be arranged within the connections 44, 46 or in association with the pump. Automatically actuated valve means are provided whereby, at each end of the stroke, that portion of the cylinder receiving the fluid under pressure is opened to the atmosphere whilst the other end is closed, preparatory to the return stroke. For this purpose, a glanded nipple 30a, at the outer end of the cylinder, -forms a stuffing box for a slidable valve member 30, which is connected, by a head 27, with a second similar valve member 31 operating in a stuffing box 33, located on the outside of the cylinder and communicating, by a pipe 45, with the inner end thereof. Axial passages in the valve members, terminating in lateral ports 38, 39, are so arranged that, on the completion of the return stroke, when a stop 41 on the piston rod engages the valve head 27, the valve members are pushed inwards as shown in Fig. 1, closing the valve 30 and opening the valve 31 in readiness for the next outward stroke, the positions being reversed when the piston, at the end of the outward stroke, engages and pushes outwards the valve member 30. The parts may be supported in the raised position, Fig. 1, by a depending plate with an upturned end engaging under a pin.

Patent GB-413787-A (GB)
Title: Improvements in or relating to circular knitting machines
IPC: D04B9/10
Filed: 1933-02-20
Abstract: 413,787. Circular knitting-machines. SPIERS, Ltd., W., XL Works, Walnut Street, Leicester, and KENT, A. W., Swithland, Leicester Road, Groby, Leicestershire. Feb. 20, 1933, No. 5169. [Class 74 (ii).] In machines having double-ended needles operated and transferred by sliders, means is provided for selectively varying the operation of the needles by moving selected sliders endwise retractively so as to enable tucking, missstitch and like effects to be produced in desired wales and courses of ribbed or plain fabric. The reverse stitch cam 1 of the plain knitting cam system A, which causes the heel and toe needles to clear before knitting on the forward strokes of the machine during reciprocatory knitting, can be moved for tuck effects from the normal position (shown dotted), to a tucking position shown in full lines. Those needles which may be transferred are actuated by normal sliders 10. The others are actuated by patterning sliders 8 arranged in alternate tricks, and differentiated one from another by different numbers and/or positions of patterning butts 25 which are acted on by some or all of selecting cams 2 (preferably at half course height). Needles pass from the forward knitting cam 5 to an upthrow cam 20 which raises them to half-course height. Certain patterning sliders are now depressed to knocking over level by the selecting cams 2, and the knitting butts 18 follow a track 19, as at c, until they are again raised to half-course height by a cam 6. The associated needles then take yarn at the feeder 7 without clearing their loops, and remain at this level until the butts are depressed by the stitch cam 5. Thus the needles draw loops of the yarn without forming them into stitches. The sliders are then again raised by cam 20 for further selection. The associated needles are caused to knit in a subsequent course to form tuck stitches. The butts of the ordinary sliders and of those patterning sliders missed by the selecting cams, are raised by cam 3, as at f, and the corresponding needles are raised to clearing height. These butts subsequently enter the knitting cam system A and normal stitches are formed. Ordinary sliders are raised by a cam 23 acting on transfer butts 24. During transference, this cam 23 also prevents accidental entry of the knitting butts in track 19, and so ensures positive action of transfer cam 22. The selecting cams 2 preferably consist of plate-like elements slidably mounted above one another, and selectively operated from a patterning device and means may be provided for holding all the cams inoperative. Patterning sliders having the maximum number of frangible butts may be provided, and butts broken off when not required. To restrict the patterning to definite portions of the fabric a group of patterning sliders may have longer butts than the remainder and the selecting cams may be movable to act only on these. The means provided by this invention may be combined with a striping attachment or yarn changing means.
