Title: Improvements relating to dog racing track hurdles
IPC: A63K3/04
Filed: 1947-03-07
Abstract: 622,052. Hurdles. O'CONNELL H E., (Representative of O'CONNELL, D.). March 7, 1947, Nos. 6379 and 6530. [Class 45] Relates to dog-track hurdles comprising sections mounted side-by-side and adapted to swing independently from an upstanding position to a lowered position if struck by a dog, each section being retained in the upstanding position by a yielding control. According to the invention the axis of pivoting of the sections is. disposed substantially at the level of the face of the track. The sections of the hurdles are of two types. One type has a rigid wooden framework comprising side members 4. 5, Fig. 6, joined by a top bar (not shown) and a cross-bar 7 and covered with canvas. The cross-bar 7 is situated at about half the height of the hurdle and is connected by a spring 24 to a supporting frame comprising a tube 12 with welded arms 14, 18 and a rear member 19 with a flanged base 20 to distribute the weight. The sections of the hurdle are pivotally mounted on the tube 12 by notched pins 21, Fig. 8, which engage a hole 22 in the tube. The spring 24 is arranged to hold the section normally upright and its tensioning nut can be adjusted through a hole 30 in one panel. The top bar carries a resilient bush 11 and has a rubber facing piece 10. Three sections are mounted on each frame so that they are readily portable. The second type of section, which is mounted at one end, provides the aperture for the hare, and comprises an inverted U-shape frame, Figs. 4 and 5, pivotally mounted on brackets 35, 45, which are mounted on spigots in concrete blocks in the track and held upright by a spring 54. The top bar 33 is cranked to provide clearance for the hare rail 1 when the hurdle is lowered. Depending from a cross-member 59 fixed to the top bar 33 is a fibre curtain 58 through which the hare can pass and, upstanding from it, is a resilient brush 57. The cross-bar is faced with a rubber cushion 60. In a modification, when the hare, aperture is intermediate the ends, two adjacent sections have their top bar 6 extended and the resulting aperture is filled with a fibre curtain depending from the extensions. As an alternative, an independent section may be used between two units of three sections comprising a . spring-retained pivotally-mounted inverted U-shape structure on a base frame carrying an upstanding brush and a depending curtain. The brush 11 may be pivotally mounted, as shown in Fig. 10, on a segment 71 which. can roll on curved faces 74, 75 of the side members being normally held in place by elastic links 72, 73.

Title: A new or improved method of manufacturing or producing chain
IPC: B21L15/00
Filed: 1945-03-15
Abstract: 589,009. Making chains. CHAIN DEVELOPMENTS, Ltd., and SMITH, W. March 15, 1945, No. 6463. [Class 83 (ii)] Chains for operating pulley blocks &c. having links of predetermined dimensions are made by cutting predetermined lengths from circular or other stock, bending into half links which are then welded in pairs, interconnecting two welded links to provide a short chain portion of three links by threading half links through each welded link and welding them together, and subsequently building up in stages by interconnecting chain portions of ever-increasing length by threading therein and welding together further pairs of half links. The flash metal resulting from the weld of each complete individual link is removed as produced and the centre link of a three-link portion is also similarly treated after welding. Two three-link portions are then united together by welding a pair of half links thereto to form a seven-link portion and the flash of the new link is then removed. After similarly joining two sevenlink portions to produce a fifteen-link portion and so on until the chain is of the desired length, the flash of the remaining centre links is then removed, the chain being held in a channelled bed or frame. Chain portions having different numbers of links may also be similarly united according to the length of chain. The stock may be fed from a drum through a straightening machine and before bending may be heated to red heat in a furnace and bent before any appreciable degree of cooling, and the ends of the half links cleaned before welding. After the chain is complete it may be heated in a normalizing furnace and may then be tested and polished by barrelling &c. One or more flash-welding machines may be used to effect the welds. The half links may be bent to U- shape for links of round or oval shape, but for stud chain-links one or both halves may be D-shaped. Specification 589,018 is referred to.

Abstract: 284,766. Siemens Bros. & Co., Ltd., Patterson. W. G., and Garnham, E. W. Didier-. March 9, 1927. Drawings to Specification. Automatic and semi-automatic exchange systems.-The circuits of a bi-directional switch are modified so that received impulses exceeding a predetermined number are without effect. The invention is described with reference to a rotary connector having two sets of wipers similar to that illustrated in Fig. 2 of Specification 284,765, modified by the dotted line connections shown therein, in which only the first incoming impulse is effective. Change-over relay C energizes when the switch is seized, and after the first impulseis received and line relay A re-energizes, relay DR(2) energizes over off-normal contact n1 and disconnects vertical magnet VM. Relay C falls back, connecting up rotary magnet RM to start the hunting movement and closing a locking circuit for relay DR(1). The subsequent operations are identical with those described in Specification 284, 765. If more than one impulse is to be effective, the relay DR may be controlled by contacts operated pn a particular level. The invention may be applied to the horizontal motion of a switch.

Abstract: 264,356. Guy, G. W., and Jarl, R. E. March 9, 1926. Electric stoves. - A stove comprises a source of heat with an associated reflector, together with an apparent source of heat simulating a coal fire, independent of the actual source and including a light reflector, the parts being arranged to provide for a circulation of air for cooling both the heat and light reflectors. The stove shown comprises an imitation fire consisting of a pair of electric light bulbs 36 mounted on a base plate 32, which is preferably slotted in order that the light shining through may give an effect similar to that of a, coal fire supported on a barred grate. A coarsemeshed screen 40 carrying pieces of coloured glass or other material simulating a coal fire, extends up behind the grate bars and over the lamps, each of which is provided with a flickerdevice consisting of a fan 46 rotated by the current of hot air and havind downward projections 47 on some, but not all; of the blades. A curved reflector 48 is arranged behind the lamps, the upper edge of which is attached to the lower edge of an upper reflector 52, preferably of polished copper. The actual source of heat comprises three detachable heating-units 54 mounted in front of the latter reflector, at the centre and. sides of the stove, and controlled by a switch which allows either the centre unit, both the side units, or all three to be used. Both the reflectors 52 are spaced from the rear panel 26, air passing up behind and cooling them, and finally being delivered over the curved top 68 of the reflector and beneath the hood 84 of the stove into the room. The heat reflector shown in Fig. 3 directs a large part of the heat down on to the imitation fuel; Fig. 5 shows a reflector directing the heat substantially forwardly, the part 74 reflecting the heat back on the part 76, which directs it outwardly. Fig. 6 shows a modified form of both the heat and light reflectors, the former reflecting the heat partly outwards and partly downwards, whilst the light reflector 50 locates the apparent centre of the fire lower and farther forward than is done by the reflector 48 shown in Fig. 3. Preferably, as in the forms shown in Figs. 5 and 6, the heat reflector shields the light reflector from direct radiation from the source of heat.
