Title: Improvements in or relating to electric signalling systems more particularly fire alarm and like systems
IPC: G08B29/16
Filed: 1936-08-10
Abstract: 479,762. Fire-alarm systems. BROOKES, N. E. (Gamewell Co.) Aug. 10, 1936, No. 21975. [Class 40 (i)] In a, fire-alarm system comprising a closed signal loop including a plurality of transmitters in series and incorporating an emergency circuit such as an earth return for use upon the development of faults, the loop is supplied by direct current for normal signalling and alternating current for emergency working or vice versa. As shown in Fig. 1, the signalling loop is supplied for normal operation from D.C. mains and includes a number of signalling boxes of different types which are adapted to transmit signals for emergency operation over an earth return circuit. A floating battery B may be connected across the supply leads 3, 4. Each leg of the loop also is fed in parallel from an A.C. source 11 through a transformer T, the secondary 12 of which is connected between earth and the legs over inductances 23, 24 and capacities 21, 22, these circuits, however, remaining inoperative in the absence of an earth at any of the signalling boxes. The normal signalling circuit includes a recorder X and a choke 10 for excluding alternating current from the D.C. supply, while the fault signal circuits include recorders Z, Y and the condensers 21, 22 for excluding direct currents from the A.C. supply. In a modification, Fig. 2 (not shown), the A.C. supply is dispensed with, the direct current for normal working being derived from A.C. mains through a rectifier bridge. In such a system, the alternating currents for emergency working are supplied continuously to the loop by a transformer the secondary of which is connected across the loop. D.C. recorders also may be connected in the circuits through the intermediary of rectifier bridges. In a further modification, an emergency A.C. source is provided comprising a motor generator which is brought into operation automatically upon failure of the normal source of supply. The alarm boxes M, N, P and S employ code sending and earthing arrangements of usual type but box R is provided with a double code wheel 90 which controls two sets of contact levers 96, 97 and 98, 99 respectively, the former set being used for normal loop signalling and the latter for transmitting signals over the earth return circuit. Non- interference magnet 100, when released due to simultaneous signalling by another box or a break in the line operates a pin 50 to prevent operation of the contacts by levers 96, 97. In a modification both sets of contacts may be operated by a single cam. In a further modification the non-interference magnet controls contacts which are adapted to shortcircuit the contacts 96, 97. Specification 248,156, [Class 40 (i)], is referred to.

Abstract: 721,123. Lubricating rails. KINKI NIPPON TETSUDO KABUSHIKI-KAISHA. Aug. 10, 1953. No. 22048/53. Class 12 (3). An automatic rail oiler comprises a bar 6 secured to an unsprung part 3 of a carriage and having a resilient portion carrying a guide roller 9 for engagement with the inner face of a rail flange, the lower end of the bar carrying an oiling device normally out of contact with the rail but adapted to have rolling contact with the inside corner of the rail when the carriage passes around a curve or partakes of "snaking" motion on the straight part of the track. As shown, the oiling device comprises a casing 10 containing a rotatably mounted ring 16 with a conical periphery part of which projects through a recess at the bottom of the casing. Oil is supplied by a pipe 12 from a reservoir on the carriage, to a chamber 18 on the casing 10. Flow to the conical ring 16 is controlled by a spring-pressed valve 19 shaped so as to supply a film of oil to the ring when it rotates. Normally the ring 16 is held just clear of the rail, by means of the guide roller, but when the carriage passes around a curve the flange of the wheel moves away slightly from the ring, allowing it to make contact with the corner of the rail so that it rotates and transfers oil to the rail.

Frames.-The upper portion of a. sewing machine frame has a laterally projecting portion to which different sewing heads may be attached in order that machines for making different seams may be built on the same frame. The application to a machine of the suspended work-supporting arm type for felling, or for flat seam work in connection with knit goods is described. The part 2 of the frame which houses the main shaft 4 by which all of the upper parts are actuated, has a lateral extension 6 provided with lugs or crossbars 7, 7<1>. The detachable sewing heads 36 have corresponding lugs 22, 23, by which they may be secured to the frame lugs by screws 24 or otherwise. The work supporting arm is supplied with the proper co-operating elements according to the head selected. Needles, driving; governing needle thread.-In the sewing-head shown, the needle-bar 37 carries three needles and is actuated by a double-armed lever 11 secured to a rock-shaft 10 and connected by a link 12 to a crank on the main shaft 4. When the sewing-head 36 is changed, the link 15 in the needle-drive is disconnected. The shaft 10 may also be changed if the auxiliary devices require it. An arm 69 having needle thread guides is secured to a shaft 70 which is positioned. in accordance with the thickness of the work by a bar 74 fixed to a sleeve 75 on the presser-bar 42. Co-operating with the needles 38 are cross thread laying fingers 39, 40, which are actuated from a vertical rock-shaft 54 by levers 61, 68. The shaft is rocked by a link 58 connected to a ball crank 57 on the end of the cross-shaft 10. Trimming.-A movable trimming blade 41 is carried by a bracket 48 fixed to a sleeve 47 which is mounted to oscillate on the presser-bar 42. The sleeve is oscillated by a link connection 51 with the rock-shaft 54, and the blade 41 cooperates with a fixed blade on the presser-foot. Presser-bar lifting device.-The presser-bar 42, which is prevented from rotating by a collar 53, is lifted by a hand or treadle-operated rod 27. The connecting link 44 is readily detachable to facilitate changing of the sewing head.
Patent GB-222309-A (GB)
Abstract: 222,309. Rider, A. Sept. 22, 1923. Circular machines.-In machines for the production of narrow tubular webs, e.g. neckties, provided with automatic mechanism for reducing at predetermined sections the thickness of the tube by removal of one or more of the knitting yarns, automatic mechanism is provided whereby the movable yarn guide, which effects removal and re-introduction of the one or more yarns, is actuated and controlled by intermediate means and a pattern disc which are additional to the usual intermediate means and pattern mechanism of the yarn-changing means. The invention is shown applied to a machine equipped with the well known type of yarn changing means comprising a number of movable yarn-guides 1 operated by slides 2 the ends of which are arranged in different horizontal planes and are selectively engaged by a cam plate (not shown) moved vertically by pattern mechanism which includes a drum 4 on a shaft 5. One of the yarn guides 1, by suitably modifying its locking catch 7 so as to miss the usual releasing member, is rendered independent of the drum 4 and is operated, through its slide 2, by a cam plate 27 and a striking plate 28, both adjustably mounted on a plunger 9 moved vertically by a lever 22 engaging a pattern disc 23, having projections 24 and recesses 25, on the shaft 5. When the lever 22 is rocked by a projection 24 the cam plate 27 intercepts the modified locking catch 7 and lifts it to put the guide 1 out of action. In another position of the plunger 9, caused by the lever 22 engaging in a recess 25, the striker plate 28 intercepts the slide 2 to put the guide 1 into feeding position. When the lever 22 rests upon the periphery of the disc 23, between a projection 24 and a recess 25, the plates 27, 28 are clear of the catch 7 and slide 2. Specification 172,847 is referred to.

Title: Improvements in or relating to change speed gears
IPC: B60K17/02
Filed: 1934-07-30
Abstract: 419,591. Change speed gearing. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT. - GES., Friedrichshafen - on - Bodensee, Germany. July 30, 1934, No. 22235. Convention date, Aug. 7, 1933. [Class 80 (ii).] In change-speed gearing upon vehicles, which is isolated by opening engine and tail clutches in changing mesh, centrifugal dogs prevent the change being effected until the gear parts have slowed down. Thus, 1, Fig. 3, is a change-speed gear element which must be slid on a splined shaft 2 to effect change of engagement. Upon the gear 1 are mounted flyweights 5 which in moving outwards centrifugally cause dogs 4, Fig. 4, to engage in transverse recesses 8, Fig. 3, in the shaft 2 when the gear 1 is in power - transmitting position. The dogs 4 prevent the gear 1 from being shifted until the rotary parts have slowed down sufficiently to obviate clash of teeth as the change is completed. The leading edges of the dogs 4 and recesses 8 are champered at 9 so that the dogs 4 are ultimately disengaged by thrust in a striker 3 tending to slide the gear 1 axially. The invention covers gearing with a free-wheel tail clutch.
