Abstract: 1414307 Percussive tools J M KENWORTHY 12 March 1973 [24 March 1972] 14001/72 Heading B4C [Also in Division B3] A press tool has a tool carrier 16 slidably mounted on a frame 14 and movable by a lever 20, the tool carrier having a percussive tool in a holder 42 which is mounted on the carrier with a lost motion connection. The lost motion connection is provided by a flange 46 on the rear of the holder movable in a spacing between a collar 44 and the carrier. An impact pin 48 is fitted to the holder and only projects into the cylinder 30 of the tool actuating device when the tool contacts a workpiece and the lost motion is taken up.

Title: Blind-stitching attachment for sewing machines
IPC: H01G4/248
Filed: 1937-05-20
Abstract: 472,308. Sewing-machines. SINGER MANUFACTURING CO. May 20, 1937, No. 14026. Convention date, June 30, 1936. [Class 112] A blind-stitching attachment has a yielding abutment with a work guide over and under which the work is folded, a carrier for the abutment and a guide for the carrier co-operating with a fixed stop. The fabric plies a, bare folded over and under the edge portion 1 of the frame 3 adjustably secured to a bracket 4 by a screw 5 and elongated slot. The bracket 4 is hinged by a pin 7 to a yoke 12 secured to the base-plate 13. The frame 3 has a downturned lug 16 penetrated by screw 15 to adjust the frame relatively to the base 13. The base 13 is anchored to the cover-plate of the machine by the plate 18 and screws 19. The attachment is thus adjustable towards and from the needle to compensate for different thicknesses of fabric. A spring 20 tends to lift the frame 3 to facilitate introduction of the work. The carrier 21 for the abutment co-operating with the frame has a part 22 formed as a presser foot with a sole portion above the feed dog 53. An actuating lever 25 is pivoted to the carrier 21 bv a screw 23. The lower end of the lever 25 has an inclined depending tail portion 26 penetrating a slot 27 in the throat plate 28 to function as a guide. When the carrier 21 is pushed away from the throat plate 28, together with the work, by the feed dog 53, and when the carrier 21 is lowered again by the descent of the feed dog, the abutment is displaced laterally during these vertical movements by the action of the tail 26 guided by the slot 27. The inclination of the tail is such that in the ascent of the carrier 21, the abutment is moved away from the needle and in the descent of the carrier, is moved towards the needle. The stitching is as shown in Fig. 5.

Filed: 1926-06-03
Abstract: 274,612. Edge, S. F., and A. C. Cars, Ltd. June 3, 1926. Cone and disc; force-transmitting mechanism.-In a disc brake for a motor vehicle wheel comprising a disc or ring 18 attached to the wheel and a floating disc or ring 17 of fibre, the latter is adapted to be pressed against the disc 18 by a brake or operating disc 1 having a limited movement connection with the axle-tree and moved by lever mechanism against the action of a spring or resilient means. The brake disc 1 is carried on spring plates 2 supported by an end plate 3 of the stub shaft carrier and is actuated through torque pins 5, Fig. 2, engaged by levers 6 pivoted on the plate 3. The free ends 7 of the levers are universally jointed to a compensating bar 8 connected at the centre by a brake actuating cable 9 which is led over a pulley 10. This pulley is on the axle-tree 4 and is preferably disposed with its axis forwardly of the front wheel pivots 14, and the interior of the nipple 12 through which the cable passes is provided with a flared bush 15, and so curved and positioned in relation to the axis 14 and pulley 10, that when the wheel is deflected in one direction the cable 9 is tightened, whilst when deflected in the opposite direction it is slackened. The Provisional Specification states that the cable may be altered in length when the wheel is deffected by the bending of the cable in the bush 12 or a combination of the foregoing constructions may be employed.

Title: Improvements in or relating to a load retaining device
IPC: B66C1/66
Filed: 1962-04-12
Abstract: 932,149. Load-supporting devices. AERPAT A.G. April 12, 1962 [April 13, 1961], No. 14131/62. Class 78 (4). A body 20 is held within a chamber 18 by balls 46 which are urged inwardly by a sleeve 48. As the body 20 is drawn upwards, by a ferrule 24 attached to a cable, it pushes a resilient band 56 outwards into a groove 58 in the sleeve 48 by moving balls 64 outwards. This movement of the band, which normally locks the sleeve in the raised position shown, allows the sleeve to be pushed down by a spring 50 thus pushing the balls 46 inwards to lock the body 20 in the chamber. To release the body, the weight is taken by the cable and the sleeve 48 is raised to allow the balls 46 to move outwards. A cable coupler 23 is attached to the body 20 by ball detents 27 held against shoulders 29 by a pin 28. The coupler is released by moving the pin 28 upwards against a spring 38 either manually or by a solenoid 41. The reduced end 42 of the pin 28 permits inward movement of the balls 27 and subsequent ejection of a barrel 26 by a spring 34, thus freeing the cable from the body 20.

The spring E is located between elements C, D having one end secured to each. Clockwise rotation of the handle 14, causes a lug 22 on the member A to engage a shoulder 38 on the element C and turn it clockwise, thereby winding up the spring: for a lug 43 on the element D presses against a lug 31 on the member B until the latter is released. Anticlockwise rotation of the handle 14, causes the lug 22 to engage the lug 43 and turn the element D anticlockwise, thereby again winding up the spring; for the shoulder 38 presses against the lug 31 until the member B is released. Two modifications are described in which the elements B, C are provided with arcuate slots.
