摘要： 843,480. Endless-belt conveyers. SMITH, J. H. W., and BALDWIN, D. T. R. May 9, 1958 [May 10, 1957], No. 14948/57. Class 78 (1). In a conveyer system for carrying articles, e.g. bundles of newspapers, in which a conveyer 1 feeds the articles on to a second conveyer 5 in controlled, spaced or timed relationship, the second conveyer travels more rapidly than the first and means is provided, which is-actuated by each article after it has left the first conveyer, to stop the feeding of further articles on to the second conveyer until the first - mentioned article has left it. The belt 1 carries rollers 3 for supporting the articles and permitting movement of the belt below them when they are stopped. These rollers are mounted in pairs in cradles 4 attached to the belt. The second conveyer consists of a pair of narrow belts 5 and a wider belt 12 between them. A vertically-movable stop 14 is disposed at each side of the belt 1 in the path of the articles and is connected to one end of a bell-crank lever 15, 16, the other end of which carries a roller 18. This roller bears against a cam 19 fast on a shaft which is connected by bevel gears to a shaft 20. This shaft is connected by chain-and-sprocket mechanism to a' shaft 28 which is connected by similar mechanism to a shaft 25. Gates 23, 24 are fast on the shafts 20, 25, respectively. If the gate 23 is at right-angles to the position shown in Fig. 1, it is engaged by the leading article and turned, thereby rotating the cam 19 to project the stop 14 into the path of the next article. When the article nears the left-hand end of the belts 5, 12, it is discharged by a push-bar moving across the belts and moves the gate 24 to a position at right-angles to that shown. The movement of the gate 24 causes the gate 23 to return to the position shown in Fig. 1 and the stop 14 to be retracted. In a modification the gate 23 is omitted. In another modification the stop actuating means includes a rocking arm which carries the stop at one end and a roller at the other which is depressed by the passage of an article.

摘要： 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.

摘要： 563,544. Photographic copying apparatus. WRAY (OPTICAL WORKS), Ltd., SMITH, A. W., and JOHNSON, B. K. March 15, 1943, No. 4215. [Class 98 (i)] Apparatus for copying documents, books, &c. comprises a table-like open structure, the top of which contains a transparent support for the original illuminated from below, and the legs of which carry a lower support for an upwardlydirected enclosed film camera, the structure carrying also a pedal coupled to the camera so that on operating the pedal the film is advanced and the shutter is actuated. Switch contacts in the circuit of the illuminating lamps may be interconnected with the shutter mechanism of the camera so that the lamps are energized only when an exposure is being made. As shown, a table 1, Fig. 1, has an aperture into which is recessed a glass plate 4 on which the document &c. is pressed face downwards by a weighted platen. Cross-bars 9 between the legs 2 support shaded; angularly-adjustable lamps 8. A shelf 5 near floor-level supports the camera 6 with lens 7 directed towards the plate 4, the camera mechanism being controlled by a spring-biassed pedal 19 operating through linkage 18 a crank 17 fixed on a shaft 16 mounted in the camera body. Shaft 16 operates through ratchet mechanism a feed sprocket 14, Fig. 4, which draws film 29 from a supply spool 8 through the exposure gate 11 and over a guide roller'10, delivering it to a take-up spool 12 which is belt-driven from the sprocket through a slipping clutch at a speed which maintains the film taut ; the ratchet mechanism permits a 90 degrees rotation of the sprocket 14 when the pedal is depressed, the sprocket remaining stationary when the pedal is released. The film is held in the exposure gate 11 by a pressure plate 30 mounted on a pivoted arm 33 retained in operative position by a spring 32 ; a spring clip may also be provided to secure the plate in position. The crank 17 has a foot adapted, when the pedal is depressed and released to rock a stirrup 41, Fig. 1, the arm 42 of which is pivoted at 43, Fig., 3, in the lens shutter casing 35, and is biassed by a spring 47. An extension of this arm is pivoted to a link 44 pivoted at 45 to a sector plate 37, the pivot pin 45 bearing against the edge of an exposure aperture 36 in a shutter slide 34 adapted to move in guides 34a across the lens aperture 46. A bracket 48 on this slide is connected on the one hand to the piston 38 of a dashpot 39 and on the other hand to a tension spring 50. With the arm 42, link 44 and sector 37 in the full-line positions shown, the lens aperture 46 is obscured by the slide 34 only. When the arm 42 is rocked by depressing the pedal, slide 34 moves to the left, stressing spring 50, until its aperture 36 registers with the lens aperture 46, but this is not uncovered because the obscuring sector 37 moves ahead of the aperture 36 in the slide. When the pedal is released, the spring 47 rocks the arm 42 back, so that the link 44 rapidly withdraws the sector 37, initiating the exposure ; owing to the action of the dashpot 38, 39 the slide 34 follows relatively slowly under pull of the spring 50, so that the lens aperture 46 remains uncovered for a period depending on the time taken by the dashpot piston 38 to uncover an air inlet 51, whereafter the spring 50 rapidly withdraws the slide 34 to its original obscuring position. This period may be regulated by pre-setting the dashpot cylinder to different positions by means of a handle 52 moving over a scale 54. Thus, depression of the pedal feeds the film and arms the shutter ; release of the pedal releases the shutter to make the exposure. To synchronise the illumination with the shutter operation, the circuit of the lamps 8 includes contacts 57, Fig. 3, normally maintained open by pressure of a rod 55, mounted on the bracket 48, against a spring 56 carrying one of the contacts. When the shutter slide begins to move to the left, the spring 56 is moved by a biassing spring 58 to close the contacts 57, thus energizing the lamps, which remain lit until the contacts 57 are opened again by the rod 55 on return of the slide 34 after exposure.

摘要： 547,264. Wheels for vehicles. SMITH, R. W. April 19, 1941, No. 5083. [Class 144 (i)] Strakes 8 are adjustably and removably secured to the steel wheels of tractors or the like by angle brackets 4 bolted to the rim 1 and having flanges, flange 7 being provided for securing the strake by means of a bolt or bolts 9 passing through one of a series of holes 13 in the strake and a curved flange 5 to which a tread 6 of rubber or the like may be secured. An additional angle bracket 10 with a lug 11 by which it may be bolted to the wheel rim may be provided to give additional support. In a modification the strakes 8 may be mounted by a pair of brackets 14, 15, Fig. 6 which may be used with or without a tread-supporting flange. The strakes can therefore be adjusted for protrusion from the wheel, withdrawn within the perimeter or removed.

摘要： 527,927. Hand wheels. SMITH, G. W. April 18, 1939, No. 11692. [Class 80 (iv)] [Also in Group XXV] Consists in an auxiliary steering wheel provided with means for readily detachably securing it to the normal steering wheel of a vehicle. The rim 1 of the auxiliary wheel is connected by three radial arms 2 to a concentric flat ring 3 which carries a number, three or four, of angularly adjustable clamping devices for clamping to the arms 5 of the normal wheel 6. Each clamping device consists of a cylindrical member 7 having a depending lug 8 which carries on hinges 9 two arms 10 the lower ends of which are hooked. The arms can be closed against the action of a spring 14 by a fly-nut 13 on a bolt 12. The member 7 is gripped between arcuate faces 16 of the two members 17 which form a split clip having an aperture 18 which accommodates the ring 3. A bolt 20 passes through the members 7, 17. By tightening the nut 22 the member 7 is forced against the ring 3. Alternatively, the ring 3 may be slotted to receive bolts from the blocks bearing against the ring. The clamping devices can be carried by the rim of the auxiliary wheel.
