Abstract: 104,707. Wade, H., (Reed & Co., C. E.). March 9, 1916. Shaping by cut. ting. - Relates to machines for removing the stubs from the toes and heels of unfinished lasts, of the kind wherein a tracer 86<a>, Fig. 5, runs around a pattern 88 and cutters 87 are constrained to move in similar paths around the lasts 89 while the pattern and lasts are fed past the tools. The cutters are mounted on rotary spindles carried, with the tracer, by a slide 57 movable on a slide 54, Fig. 2, and the work is fed past the tools by the descent of the work-holder. The pattern and lasts are secured between side clamps 237, 239, 241, 242, Fig. 5, carried by bars 210, 211 adjustable towards each other on the converging faces of the work-carrier 203 to suit the length of the lasts, and the side clamps are carried by bars 216, 217 relatively slidable in the bars 210, 211, so that the space be. tween them can be adjusted to the width of the lasts. The lasts are further held down by clamping-plates 254, 255. The carrier 203 is pivoted at 206 to a slide 161, Fig. 2, so that when the toes are finished it can, be reversed to bring the heels to the cutters without moving the lasts in the carrier; it is supported bv a rod 281 slidable in a tube 275 pivoted to the slide 161, and the rod 281 is provided with a rack engaging a locking- pinion controlled by a handle 280 for reversing and locking the work-carrier. The slide 161 and the work-carrier 203 are partly counterbalanced and are adapted to descend slowly under the action of gravity and a dash-pot 176 in known manner to feed the work past the cutters. The work carriage is set at the different heights necessary preparatory to operating upon the toes and heels respectively, by raising it until a catch-piece 362<a> formed at one end of the lever 361, Fig. 17, carried by the carriage engages with either of two adjustable stops 354, 355 on the machine frame. The lever is rocked on a pivot 360 to set the catchpiece to engage with the appropriate stop by an eccentric pin 365 on the axle 206 of the workholder. The clamps which press the lasts against the face of the work-holder may be formed in two sections 500, 501, Fig. 29, connected together by a pivot 502. Ball bearings 162, Fig. 21, are provided between the work carriage and the machine frame. The balls occupy holes in a plate 169, in which is mounted a pinion 172 in gear with racks 174, 175 secured respectively to the machine frame and the carriage.

Title: Improvements in grabs
IPC: B66C3/08
Filed: 1922-02-07
Abstract: 201,945. Wellington, J. M., and Mackenzie, D. G. Feb. 7, 1922. Grab-buckets.-A guard 7, pivoted on the suspending-hook 3 of a grab of the single-chain type, co-operates with the lifting rope or chain 2 and with the discharging-ring 4 to ensure the correct engagement and disengagement of the hook with the ring. The invention is described in connection with a grab operated by a rope 2 and provided with the device described in Specification 143,963 for controlling the angular position of the hook 3 from the buckets. The guard 7 consists of a pair of plates shaped as shown at 7<1>, 7<11>, 7<111>, and spaced apart by rollers 9, 10, 11, 12 to enclose the hook 3 and rope 2. The guard is pivoted at 6 on lugs on the hook. The rope passes between the rollers 10, 9 as shown. When the loaded grab is being raised, the hook is in the inclined position, as shown in Fig. 2, and the rope 2 bears against the rollers 11, 9, so that the part 7<1> of the guard engages the discharging- ring and draws it beneath the hook 3. When the grab has been discharged and is open, the hook 3 is vertical, and the rope 2 bears against the roller 10 so that the part 7<11> of the guard projects beyond the hook as shown in Fig. 1, and the hook is prevented from engaging when the grab is raised and lowered through the ring.

Title: Actuating mechanism for automatic grab-bucket
IPC: B66C3/08
Filed: 1949-02-10
Abstract: 664,184. Grab-buckets; opening and closing mechanism. ALLARD, P. J. M. T. Feb. 10, 1949. [Feb. 11, 1948] No. 3648/49. Class 78 (iv)] In the grab shown in Figs. 1 and 2, bucket elements 3 are secured to blocks 7 journalled on fixed shafts 6 housed bv tubes 5 joining two casings 4 which house the opening and closing mechanisms for the bucket. A closing and lifting cable 1 passes around a drum 12 secured to a shaft 13 which carries at each end a pinion 14 engaging teeth formed in a slot 16 in a quadrant member 17 pivoted at 18 to the enclosing casing 4. Each quadrant member 17 is joined by links 21, 21 to cranks 23 on the blocks 7 so that as the drum 12 is turned by the rope 1, the resulting rotation of the quadrant member 17 closes the bucket. The bucket is opened by two ropes 2 connected to levers 24 on a shaft 26 carrying a crank 28 within each casing 4, the cranks 28 being connected by links 30 pivoted at 31 to the quadrant members 17 to move the latter in a direction to open the bucket. In the fully closed position a projection on a flange on the drum 12 may be arranged to engage a pawl on the shaft 26 so that the weight of the grab is not taken by the closing mechanism : the pawl may be rigid with the shaft 26 or biassed by a spring relativelv thereto so that it is withdrawn from the path of the projection when the levers 24 and shaft 26 are turned by the opening ropes 2. Alternative constructions in which there are two closing ropes or in which the drum 12 is driven by worm gearing from an electric motor mounted on the grab, instead of by ropes, are described. Fig. 11 shows a grab controlled by a single rope. The opening lever 24 is linked to a slider 46 which is engaged by pawls 42 on the usual crown 41 when a ring 43 normally resting on the tails of the pawls 42 is supported by a platform 49 on the grab. When the rope is then slackened the lever 24 turns the shaft 26 to open the grab as in Figs. 1 and 2. It also acts through a spring 54 to engage a detent 51 with a ratchet wheel 50 on the drum 12. The detent holds the grab open when it is raised slightly to disengage the pawls 42 from the slider 46 and during subsequent lowering. It is retracted by the spring 54 when the grab rests on the material with the rope 1 slack : the grab may then be closed by the rope. Specification 628,045 is referred to.

Title: Pneumatically-Hydraulically Operated Servo-Brake
IPC: B60T13/573
Filed: 1967-01-31
Abstract: 1,162,855. Brake servos. ERNST HEINKEL A.G. 31 Jan., 1967 [17 Dec., 1966], No. 4564/67. Heading F2F. In a servo-brake a brake pedal 1, Fig. 1, acts through a ram 2 forming part of a valve system on a reaction piston 11 which is freely displaceable relatively to a pneumatic working piston 15 acting on a main hydraulic brake piston 18 and the servo pressure acts simultaneously on the pistons 11 and 15 through a common pressure-responsive sealing means 12. In the inoperative position shown in Fig. 1 a vacuum exists in chambers A, B, C, D and E and ambient pressure is present in chamber F between filter 6 and slide valve 5. With manual pedal operation ram 2 urges valve piston 3 against spring 19 until valve 5, under the loading of spring 7, engages valve seat 81. This establishes two separate chamber systems A, B and C, D, E in which vacuum still prevails. Further manual movement of valve piston 3 unseats seal 301 thus opening a path for the ambient pressure in chamber F to penetrate via passages 303, 304 into reaction chamber C and thence into chambers D and E. This is the position illustrated in Fig. 3 (not shown). The resulting movement of piston 15 is transmitted via ram 17 to the main hydraulic piston 18 to create pressure in brake pipe lines (26, 27), Fig. 4 (not shown). The ambient pressure in chamber D causes movement of reaction piston 12 which is transmitted back to the driver's foot via valve piston 3, brake ram 2 and the brake pedal to give a reaction pressure which has a linear relationship with the effective brake pressure.
