Title: Improvements in or connected with apparatus for shrinking metal tyres on wheels
IPC: B60B31/00
Filed: 1921-10-29
Abstract: 187,460. Duncan (Partick Foundry), Ltd., R., and Duncan, W. L. Oct. 29, 1921. Building-apparatus.-Apparatus for shrinking metal tyres on wheels consists of a platform A which carries the wheel and is mounted on a water tank B in such a manner that, normally, it lies horizontally above the level of the water and, when required, can be tilted so as to submerge a portion of its surface. In the construction described the tank is substantially the shape of a quarter of a sphere and the platform is mounted on trunnions diametrically disposed at the straight side of the tank. In its horizontal position, the platform is supported by the edge of the tank and by a pivoted latch D. The wheel is secured on the platform by a spindle E and clamp nuts at the top and bottom, either of which can be slackened when the platform is tilted to allow the wheel to be turned so as to pass the whole of the tyre through the water. The arrangement shown in Fig. 3 is adapted to slacken the wheel automatically when the platform is tilted. The lower end of the spindle E elides non-rotatably in the platform and has a yoke extension 9 adapted to ride over a cam rail H, which, in the tilting movement of the platform, slides the spindle outwards. The platform can be held vertical by pushing the spindle inwards to engage the inner end of the yoke over a stop K.

Title: Improvements in and relating to electric lamp adapters
IPC: H01R33/94
Filed: 1939-10-27
Abstract: 533,280. Lamp-holders. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 27, 1939, No. 28814. Convention date, Oct. 28, 1938. [Class 38 (i)] An adapter for carrying a reflector to convert a lamp tc indirect lighting, consists of an insulating body 10 made in twc identical halves, the central section 13 contain a lampsocket 24 and the lower end a plug 31 to fit a supply socket, the upper end 14 constituting a shield surrounding part of the lamp and carrying a reflector 11 to surround the remainder. The twc halves of the body are held together by the contact shell 33 and by the reflector 11 which is held against a shoulder 39 by a spring ring 37 that snaps into a groove 36.

Title: Feed adjusting means for hammer mills, pneumatic conveyors and the like suction-operated means
IPC: B65G53/42
Filed: 1955-10-10
Abstract: 775,262. Pneumatic conveyers. ABONNENC, J. Oct. 10, 1955 [Oct. 15, 1954; April 15, 1955; April 15, 1955], No. 28828/55. Class 78 (1). [Also in Group XL (b)] Material to be crushed or conveyed passes into the apparatus through rectangular openings A, B and C formed between a curved partition 2 and the front and rear walls of a casing. The material drops through the opening A on to the bottom 5 of the casing and is then sucked through the opening B. When the input increases, the upper surface EF, Fig. 4, of the material rises towards the lower edge CD of the partition 2 until clogging occurs. Just before this happens, the upper surface of the material is at XY and control apparatus is provided for regulating the feed so that the surface remains in that position. A photo-cell type detector, or an electronic presence detector, causes actuation of an electric motor 8, Fig. 3 which traverses a nut 10 operatively associated with a lever 12 connected to a gate 14 at the end of the feed channel. Switches 16, 17 actuated by the nut at the ends of its movement, stop the motor in correspondence with the closing and opening of the gate 14, respectively, and also actuate sound or optical signals to indicate that the feed is empty while the gate remains open, or conversely that the adjusting means is still clogged while the gate remains closed. The action of one form of detector (not shown) depends on whether or not it is covered by the material. Such a detector may be used in conjunction with a photo-cell type detector to provide a maximum and minimum detector. In another form a beam of light 28, Fig. 7, from a source 23 falls on the cell 24 when the material is below the predetermined level. The light source may be adjusted vertically or angularly. A maximum and minimum detector may consist of light sources 32a, 32b, Fig. 9, and cells 34a, 34b. The projectors may be arranged in a common casing located at the middle of the material. Additional air may enter through a channel 53, Fig. 12, between a plate 52 and the upturned end of the curved partition 50 and through an aperture or slot 54. In a modification the upper end 56, Fig. 13, of the plate 52 is curved over the top of the extension of the partition and an adjustable plate 57 regulates the amount of air admitted. A curved plate 59 mounted on the partition 50 extends over a trough 61 in which collects any material projected below the partition. The position of the trough 61 is adjustable by a lever 62.

Abstract: 246,804. Wolfer, A., and Maurer, P., (trading as Von Berg & Wolfer). Jan. 27, 1925, [Convention date]. Envelopes and the like, making.-In a machine for folding and sealing letters in an envelope or wrapper folded at the same time, as the enclosed letter and then sealed, the envelopes 1, Fig. 9, are automatically fed into position before the first folding operation. The envelopes are fed as a, continuous strip 21, Fig. 3, and reciprocating hooks 28 with tapered sliding faces engages in holes 39 in the envelopes when moving in the direction of feed and disengage when moving in the opposite direction. A cutter 40 operated in conjunction with the movement of the hooks detaches the individual prepared envelopes from the strip. The strip can be withdrawn from within reach of the hooks by rotating a guide 23 about a pivot 26. The strip winds off a supply roll 66, Fig. 2, and depends in a loop engaged by a feeler 67 which, when the loop shortens, operates a clutch so that the roll is unwound positively. The enclosure 2 is placed on a table 4 by hand or by a mechanism similar to that used in printing presses, and the enclosure and envelope are folded along line 41 of the envelope by a blade 7, Fig. 1, and rollers 9. The letter falls along a slipway 10 to a table 13 where the letter is positioned by a movable stop finger 43. Above the table 13 are a gumming plate 48 and a retaining-plate 47, Fig. 7, which presses on the letter during gumming. Adhesive is applied to a gumming-edge 49 by a roller 51 which is pressed upwards by a lever 52 carrying rollers 55 which run under guides 53. The letter is folded along line 56 by a blade 14 and roller 16, which are shorter than the envelope to prevent rolling out the gummed edges. The letter falls to a press consisting of two electrically heated frame plates 18, which act on the edges of the envelope and carry two spring-pressed inner plates 65. The machine may be used in combination with devices for stamping printing, and addressing the envelopes.

Abstract: 176,041. Rafferty, W. F., and Haines, F. M. Oct. 20, 1920. Skid; scotch blocks.-In a brake for railway vehicles, of the kind in which wedge blocks are adapted to be engaged between the wheels and the rails, the blocks 1 are normally suspended by a spring 16 and a rod 12 attached to a transverse yoke or frame 12 extending between the blocks. The spring 16 is secured at its other end to the underside of the vehicle and the rod 12 to a hand-lever 15 extending through the vehicle floor. Slotted bars 20 fixed to the blocks embrace similarly shaped brackets 18 fixed to the vehicle.
