Title: Improvements in or relating to emergency exits more particularly for closed passenger vehicles
IPC: B60J9/02
Filed: 1932-02-04
Abstract: 396,441. Vehicle emergency-exits; doors; fastenings. LONDON GENERAL OMNIBUS CO., Ltd., 55, Broadway, Westminster, and HAIGH, D., 7, The Close, Spring Grove Road, Isleworth, Middlesex. Feb. 4, 1932, No. 3342. [Class 108 (i).] In emergency-exits or doors for road vehicles, aeroplanes, buildings, &c. having locking means, a manually - operated striker is provided for releasing the locking mechanism and a frangible insert is disposed between the striker and the locking means so that it must be fractured when the striker is operated to release the locking mechanism. As shown in Figs. 2 and 3, a hinged panel for a closed vehicle is provided with latches 24 adapted to engage pocketed striker-plates 25. The latches are spring pressed and are disengaged by means of a lever 36 which contacts with rocker arms 40, 41. On the inside of the vehicle a striker 44 is pivoted to the frame and bears on a glass insert 32 the arrangement being such that on operating the striker 44 the glass 32 is broken and the striker then contacts with the lever 36 and releases the latches, continued movement of the striker opening the panel &c. As shown, the latches 24 are all operated from one striker. Fig. 9 shows the arrangement applied to the door of a building the striker lever 44 operating the releasing lever 36 after breaking a sheet of glass 54.

Title: Improvements in shock absorbers
IPC: F16F9/49
Filed: 1923-02-05
Abstract: 204,635. Kerr, B. Feb. 5, 1923. Dash-pots.-In a shockabsorber of the dashpot type for vehicles, means are provided wherebv the recoil is cushioned from its commencement to approximately the normal loaded position of the suspension spring and the remaining movements in both directions are left comparatively free. A cylinder 10, Fig. 2, having working therein a piston 17 with spring-controlled valves 27, is provided at its upper part with a bypass comprising a jacket 14 communicating with the interior of the cylinder 10 by apertures 15, 16. On the downward motion of the piston, the fluid, which may be air, passes freely from the lower side of the piston to the upper through valves 2'7 and the by-pass. On the upward movement the valves close and the air above and below is compressed and rarified respectively, so providing a check action for the recoil until the piston reaches the lower end of the by-pass, when the upward motion of the piston ceases to be retarded. At the commencement of the upward movement, the velocity of the piston is comparatively slow owing to the fact that the suspension springs are overcoming the inertia of the vehicle body; the velocity is then increased and subsequently is retarded by the compression until the by-pass is reached. In a modification, the cylinder communicates with a reservoir by means of a tube 37, Fig. 5, and an inwardly opening valve 32 which is closed only when the pressure in the cylinder rises.

Abstract: 1417205 Conveyers EASTMAN KODAK CO 23 Jan 1973 [24 Jan 1972] 3445/73 Heading B8A Film cartridges to be filled in a spooling machine are automatically unloaded from a tray 16 at an in-feed section 10, fed via an indexing mechanism 18 and conveyers 22, 26 to the machine, after which they are fed, by a mechanism 36 and conveyers 34, 36, on to an empty tray of an out-feed section 12. The trays have compartments 40 each provided with an elongated opening 42 through which bars 54 for lifting the cartridges may move upwardly. In order to prevent tilting of the cartridges when they are lifted they are engageable by a plurality of bars 80 which are vertically movable relative to a frame 77 and which may fall under gravity or be latched in a raised position. The frame 77, which forms part of the mechanism 18, also has a depending bar 126 for sweeping rows of cartridges off the bars 54 on to T-shaped bars 98 of an endless conveyer 128 of the mechanism 18. The cartridges are transferred from the bars 98 to the conveyer 22 by pushers 142 secured to a driven chain 140. At a transfer station 24 a pusher mechanism 150 transfers the cartridges one by one into the spooler conveyer 26. The outfeed section 12, which is fed filled cartridges by the conveyer 28 rearranges the cartridges, by means of the indexing mechanism 36, into adjacent rows for sweeping on to elevator bars 178 which extend upwardly through an empty tray. After the bars have been lowered, the tray is manually removed and a sweep mechanism (not shown) returns to a position above the indexing mechanism 36. The trays at both sections 10, 12 are releasably clamped and the operation of the various transfer-conveyer mechanisms are automatically controlled by photocells, relays and logic controls.

Title: Apparatus for mechanically transferring bottles or other glass ware
IPC: C03B35/12
Filed: 1936-02-07
Abstract: 469,912. Stacking glassware in leers. PEARSON, T. F. Feb. 7, 1936, No. 3729. [Class 56] [Also in Group XXX] A method of delivering articles of glassware to a leer consists in picking up an article at the end of an arm, rotating the arm through 180‹ and moving it in a linear path, and then releasing the article when the arm has reached the end of its linear travel. The bottles or like articles are engaged one at a time by gripping-members 3, 4 pivoted at 7 and normally closed by a spring 12 but opened at the receiving and delivery stations by the engagement of members 14 with fixed ramps or with pivoted gravity latches 51, 57 which are raised and tripped by movement of the carrier in one direction but act to lift the member 14 on the return stroke. The transference comprises three movements as follows : (1) The carrier 1 carrying the gripping members moves to-and-fro in the guides 20 along the arm 21 through the agency of a continuously-driven shaft 24 cut with interlacing right-and-left hand screw threads running into one another at the ends. A pin 25 on the carrier engages the thread to effect this movement ; (2) During this movement a pinion 18 on the carrier engages a short rack 33 on the arm and operates gearing 17 to rotate the carrier through 180‹ as' shown in dotted lines; (3) The arm 21 is swung slowly to-and-fro about the pivot 49 by a link 46 carrying a roller engaging a face cam slot in a member 40. All the mechanism is driven from the main power shaft 32. Preferably the arm 21 is duplicated so that the two arms have a V-formation which is moved as a unit, the carriers in such a case being arranged so that one is moving inwards while the other is moving outwards along the arm. In operation the arms swing slowly and each serves one half of the leer so that the carriers can arrange the bottles in rows in the two halves of the leer.

Title: Improvements in or relating to electrical signalling and telephone systems
IPC: G08B27/00
Filed: 1953-02-12
Abstract: 733,945. Electric selective signalling. ERICSSON TELEPHONES, Ltd., and STEVENS, J. R. H. Feb. 12, 1953, No. 3942/53. Class 40(1). [Also in Group XXXIX] In a signalling system in which a first signal is sent over a two-wire line by alternating current, and a second signal by pulsating direct current, means is provided at one or more receiving points which responds to alternating current but gives no signal, and responds to pulsating direct current to provide the second signal ; the said means including four rectifiers connected in bridge formation across the line and two relays connected one in each of two arms of the bridge. As shown, with the key KB/KC normal the alternating current output of magneto generator G rings a polarized bell (not shown) to provide the first signal. This current also operates relays X and Y, which hold from cycle to cycle, whereupon C, AA and BB all pull up. At the end of the signal, relay C relapses but AA and BB hold up. If KB is then operated and the generator G is again turned, the resulting pulsating direct current operates X, thus releasing AA which remains down when X restores at the end of the signal. Next, with KC operated the output from G operates Y, thus releasing BB. As soon as Y restores, D pulls up, and remains held, so that the bell BL is rung to provide the second signal. This arrangement, which requires pulsating direct current in both directions sequentially to provide the second signal, is unlikely to result in false operation. In the embodiment of Fig. 2 (not shown) relays X and Y are operated in the same way but the bell control circuit is less complex. Two relays A and B are normally operated over their first windings and back X and back Y contacts, respectively, and simultaneous operation of X and Y results in A and B holding over their second windings and front X and front Y contacts in series. However, operation of X or Y alone results in release of A or B, the relevant one of which then completes a local circuit for the bell BL. The second signal is thus provided in response to pulsating direct current in either direction. In the even simpler arrangement of Fig. 1 (not shown) X and Y are the only relays and the bell circuit is completed over front X and back Y contacts in series, so that the second signal is provided in response to pulsating direct current in one direction only.

Filed: 1932-02-10
Abstract: 391,568. Coin - freed amusement apparatus. DEHN, F. B., 103, Kingsway, London.-(Mills Novelty Co. ; 4100, Fullerton Avenue, Chicago, U.S.A.) Feb. 10, 1932, No. 4015. [Class 27.] Relates to coin-operated machines of the kind described in Specifications 309,627 and 324,941, [both in Class 27, Coin-freed apparatus &c.], in which a number of reels 59 are set rotating and are subsequently stopped automatically by stop levers 65 pivoted at 67, or in advance of the automatic stop by skill control devices 124, the reels, according to their stopping positions, controlling a prize delivery mechanism which is effective only when the skill-control device is used. According to the invention, the stopping lugs 68, which engage star-wheels 69 connected to the reels, are carried by sections 97 slidably mounted by pins and slots 98, 99 on the members 95 which are pivoted at 96 to the main portions 94 of the stop levers and are rocked to stop the reels when the skill control devices are used. The arrangement is such that the stop levers are automatically shortened, when the skill-control is used, so that the reels are stopped in a different series of positions from those in which they are stopped when the stop levers act automatically. Each section 97 is held projected by a bell-crank lever 101 pivoted at 104 to the lever section 94 and retained in latching position as shown by a spring 105. Pins 133, 134 are provided on a bar 135 adjustably secured at 136 to each link 185 which connects the skill-control devices 124 to the locking bars 109 that render the members 95 rigid with the members 94. When the skill control is used, the pins 134 release the bell-crank levers 101 thereby allowing the sections 97 to move downwardly by gravity on the members 95 and shorten the stop levers. On the next actuation of the machine, the stop levers are withdrawn from the star-wheels, the bars 109 returned to locking position, and the links 115 raised. During this return of the parts, the pins 133 engage arms 137 on the sections 97 and move these outwardly to normal position, after which the cycle of operations will be repeated. If the skill control is not used, the members 94, 95 move automatically as a unit to stop the reels and the sections 97 remain in extended position.
