Title: Improvements in or relating to the production of text composition comprising or containing accented characters in record-strip-controlled single-typecasting and composing machines
IPC: B41B5/02
Filed: 1939-11-15
Abstract: 538,829. Type-making machines. ELLIOTT, R. C., and MONOTYPE CORPORATION, Ltd. Nov. 15, 1939, No. 30125. [Class 100 (iii)] In means for casting accented characters in single-type composing and casting machines,. in which the accents are formed on separate type bodies of smaller point-size than the characters, two type-high mould-blades are arranged side by side in the mould, and separate and independent devices are provided for controlling the :setting of each of the blades for both of the point-sizes to be cast. The body parts B<SP>4</SP>, B', Figs. 6, 7, 8 and 9, of the two blades B, B<SP>1</SP> are of the full point-size of the mould-cavity, and that of the blade B<SP>1</SP> rests on top of that of the blade B with capacity for relative movement. Each blade has a forward end B<SP>2</SP>, B<SP>6</SP> of full type-height, these two parts lying side by side, and each being, say, one-half the pointsize of the mould. The blade B is operated in the usual manner. The blade B' is either moved back with it to dimension the mould for the large size of body, when character-types are to be cast, or is held in the forward position, so that the mould-cavity is formed by the blade B alone, for casting accent-types. The blade B' is operated by mechanism, which is of known form for operating a cut-off blade for casting lowquads. This comprises a lever engaging the blade, and two pivoted actuators E, E<SP>1</SP>, Fig. 11, which serve to move the blade in opposite directions. The actuator required is operated by a control-lever G, which is horizontally adjustable on a vertically rocking arm of the machine. The lever G is positioned by a doubleacting air-motor C, which is governed by two distinct signals in the record-strip. The motor adjusts a pivoted setting-member or switch H, which moves the control-lever into one or the other position of adjustment when the arm carrying the lever rises.

Title: Improvements in portable electric flashlight with retractable mount for auxiliary lamp
IPC: F21L2/00
Filed: 1951-12-28
Abstract: 711,817. Electric battery lamps. DEHN, S. G. (Hyman, H.). Dec. 28, 1951, No. 30331/51. Class 39 (2) An electric battery lamp, comprising a casing 24 provided with a head 26 containing a bulb 36 is provided with an auxiliary lamp carried by a tubular standard or sleeve 122 that is pivoted at one end to the head of the casing, the bulb 138 of the auxiliary lamp being mounted in a lamp holder which is normally seated in the end of the sleeve 122 and can be withdrawn to an extended position, as shown in Fig. 8, connection to the centre contact of the bulb being maintained by a flexible insulated lead 144 extending within the sleeve and through a short flexible metallic conduit 216. The inner end of the conduit 216 is mounted in a cup 218 formed with resilient fingers 224 whereby the cup is retained frictionally in any intermediate position within the sleeve 122. A sliding switch 80 on the casing is associated with a push button for flashing, and the particular lamp which is lighted is determined by a change-over switch dependent on the position of the sleeve 122 relative to the lamp casing. The sleeve 122 is pivoted between a pair of lugs near the upper end of the casing, the end of the sleeve being bifurcated and the side parts thereof flattened to receive between them the change-over switching device which is mounted on the pivot 134 supporting the sleeve. The change-over device comprises an insulating disc 148 partially housed within a metal cup 172, and an insulating disc 146 partially housed within a metal cup 158, the latter having a slot 168 through which projects a cam lug 156 on the disc 146. A metal tab 184 on the cup 172 is connected by the flexible lead 144 to the centre contact of the auxiliary bulb 138. The arrangement, Fig. 12, is such that when the sleeve 122 is in its inner position the cam lug 156 bears upon a conducting strip 189 which presses a contact strip 116 against the reflector 34 of the main bulb 36, so that the circuit of that bulb can then be controlled by the sliding switch 80 on the casing. When, however, the sleeve 122 is swung outwards from the casing the cam portion 156 is moved to an inoperative position, and the adjacent metal cup 172 is engaged by the tip 196 of a conducting strip 202 which has its base connected permanently to the central terminal of the uppermost battery 60. The relative arrangement of the cam 156 is such that when the sleeve 122 is brought towards the lamp casing 24 the tip of conducting strip 202 is moved away from the metal cup 172 of the change-over switch, thereby changing to the main bulb circuit simultaneously with the cam 156 acting on the strips 189 and 116 to close that part of the main bulb circuit.

Abstract: 724,522. Belt, rope and chain gearing. RENOLD CHAINS, Ltd., [formerly RENOLD & COVENTRY CHAIN CO.]. Dec. 4, 1952 [Dec. 28, 1951], No. 30337/51. Class 80 (1). A tensioning device com prises rollers 2 bearing agains a chain and carried on the end of a plunger 10 in a bore of a fixed housing 12. The plunger 10 is passed outwardly by a spring 20, the other end o which bears against a cylinder 18 sliding within a bore of the plunger. A helical groove 24 is formed on the surface of the cylinder 18 the upper wall 26 of which is plain whilst the lower wall 28 is serrated. A radially disposed pin 30 on the plunger 10 engages in the groove 24 whereby free move ment outwards of the plunge 10 under the spring pressure is allowed owing to the pin 3( running along the plain wall 26 of the groove 24 and rotating the cylinder 18 whilst inward movement of the plunger is pre vented by the pin 30 engaging in the serrations of the lower wall 28. In order to draw the plunger back into its housing 12 when required, for replacing a chain, for example, the cylinder 18 can be rotated by means of a key inserted through the bottom of housing 12, the pin 30 running out of the groove 24 and engaging behind the end face of the cylinder 18 to hold the spring 20 in compression. The action of the spring 20 can be assisted by oil fed through a spigot 35 which can also pass through a passage 36 to the bearings of the rollers 2. The rollers 2 may be replaced by a single wide roller for a belt, a toothed wheel for a chain or a grooved pulley for a rope or a pad for bearing against a chain may be provided. The cylinder 18 may surround the plunger 10 instead of working inside it and the pin 30 may be provided on the cylinder 18 and the groove 24 in the plunger 10. Both surfaces of the groove 24 may be smooth and the respective surfaces of the engaging pin may have different coefficients of friction, for example one surface might be of rubber. To allow some return movement of the plunger 10 to compensate for temperature expansion and unevenness of the chain the groove 24 may be of greater width and separate pins or projections can be provided for engaging the opposite walls. Specification 724,523 is referred to.

Title: Vehicle suspension spring rebound check
IPC: F16F7/06
Filed: 1932-10-31
Abstract: 407,442. Shock-absorbers. McNEIL, W., 1, Bond Street, Sydney, Australia. Oct. 31, 1932, No. 30498. Convention date, Nov. 6, 1931. [Class 108 (iii).] In a vehicle vibration-damper in which a C-spring faced with friction material, free at one end and attached at the other end to a control member coacts with a drum by its own expansion and contraction, means are provided for automatically latching the C-spring out of operative relation with respect to the drum throughout a predetermined range of rebound flexure of the suspension spring, and for automatically releasing the C-spring to damp rebound in excess of the predetermined free range. In one form, the C-spring 43 is pivoted at one end to a pin 40 carried by a fixed hub 21 and co-operates with a drum 33 rotated in a clockwise direction by a band 37 against the action of a torsion spring. A spring pressed toe-piece 50 of a rocking lever pivoted to the hub 21 engages the turned up free end of the C-spring 43 holding it inoperative. On approach of the vehicle frame and axle and consequent slackening of the band 37, the drum and a cam-member 56 secured thereto are rotated anti-clockwise, causing the cam to engage a tappet 55 on the lever and free the end of the C-spring. Thus on subsequent rebound the band goes on with servo action. The end of the C-spring may be bent at rightangles and a bevelled toe-piece inserted. In a modification, the lever is a spring-pressed plunger 60, Fig. 5, retracted by a cam 65 engaging a tappet 68. In a further modification, the drum carries the C-spring 78, Fig. 6, and a spring-pressed plunger 76. Rotation of the drum in an anti-clockwise direction causes the plunger 76 to be lifted by a fixed cam 82, to free the end of the C-spring. In a modification of this arrangement a wiper pivoted to the drum is interposed between the cam and plunger. The C-spring facing is placed on in sections or is cut or scoured transversely. A plurality of C-springs and latching-means may be provided.
