Title: Improvements in and relating to drives for electric locomotives
IPC: F16D3/62
Filed: 1933-03-01
Abstract: 417,448. Conveying circular motion. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Constructions Electriques de France (Soc. Anon.) ; 38, Avenue Kleber, Paris.) March 1, 1933, No. 6288. Convention date, March 1, 1932. [Classes 80 (ii) and 80 (iii).] In a linkwork drive between the driving or track wheels of an electric locomotive and the motor fixedly mounted on the locomotive frame, the links are all jointed by means of ball or rollers bearings and some or all of them are flexibly constructed. In the example illustrated, pins or journals 3 on the track wheel 2 carry links 5, the other ends of which are jointed at 6 in the forked ends of a plate member 8, constrained to move parallel to the wheel by guides 9 and cut away to clear the axle 1. The member 8 is in turn connected in a similar manner to journals 10 of the motor shaft, which pass through ample openings 12 in the track wheel, the connecting links being built up of four steel blades 16, Fig. 3, and their connections including universals at each end. Alternatively, the links 5 may be of the construction just described ; also the blades 16 may be of any desired member or section. The Specification 401,552, (Figs. 6-12) shows other similar systems to which the invention may be applied.

Title: Improvements in or relating to engine starter gearing
IPC: F02N11/08
Filed: 1942-05-11
Abstract: 557,296. Turning-gear. BENDIX AVIATION CORPORATION. May 11, 1942, No. 6353. Convention date, May 9, 1941. [Class 7(v)] A detent 12 for opposing rotation of the starter-pinion 3 is caused to engage the pinion momentarily upon actuation of the starting motor 1 and is afterwards held in idle position until the motor is de-energized and then reenergized. As shown, the pinion 3 travels axially on a threaded shaft 2 driven through a yielding coupling 5 from the motor 1. The detent 12 is normally disengaged by a spring 21 from the pinion 3, and is controlled by an electromagnet 19 connected through contacts 25, 26 to the circuit 11 of the battery 7 and motor 1. On closing the starter switch 9, the electromagnet 19 causes the detent to engage the teeth of the pinion to ensure its axial movement. Contacts 33, 34 on the armature 16 of the electromagnet bridge a resistance 36, which then passes sufficient current to cause a coil 28 to actuate the contact 25 to break the circuit of the electromagnet, allowing the detent to be withdrawn by the spring 21. The coil 28 then holds the contact 25 open until the starter switch 9 is released. In a modification, Fig. 2, the starter switch 39 is electrically operated by means of a control circuit 43, 45 including a resistance 44 bridged by a switch 46 closed by an electromagnet 47 which also actuates the detent 48. The electromagnet 47 is connected to a switch 52 actuated by a solenoid 54 connected to the motor circuit 11. A manual switch 42 closes the control circuit through the resistance 44, which prevents immediate actuation of the switch 39. The solenoid 47 momentarily effects engagement of the detent 48 with the pinion 3, and also closes the switch 46, bridging the resistance 44 and causing actuation of the switch 39. The solenoid 54 opens the switch 52, preferably after a time interval, so that the detent 47 is released but the switch 39 is held closed by current through the resistance 44.

Title: Chaser assembly for taps and die heads
IPC: B23G5/10
Filed: 1941-05-17
Abstract: 547,090. Taps and dies. LANDIS MACHINE CO. May 17, 1941, No. 6387. Convention date, May 22, 1940. [Class 83 (iii)] Chaser assemblies for taps and die heads have circular chasers mounted on the holders for limited rotational adjustment under the control of selflocking eccentric means. The chaser is clamped against a flat face 21 on the holder 11 by a central screw 14. Splined in a recess in the chaser at 50 is a bushing 31 having clutch teeth engaging corresponding teeth in a bushing 30 located, together with the clutch part of the bushing 31, in acounterbore in the holder. The bushing 30 has a recess receiving the eccentric end 66 of a pin 60 located in a bore in the holder against a shoulder 69, and provided with a recess 70 for a key. The bush 31 is pivoted in the chaser at 35 and the depth of the splines is greater than the depth of the clutch teeth. By slackening the screw 14 the clutch teeth may be disengaged to effect a major adjustment. Fine adjustment is effected by the eccentric 66 which has a range only slightly greater than that caused by a shift of one clutch tooth. The eccentric end is adapted to act as a breaking piece to protect the other parts of the assembly. The clutch teeth are shaped as shown in Fig. 6 so that the cutting thrust is taken up on surfaces parallel to the axis and any tendency to force the chasers off their seating faces is avoided. U.S.A. Specification 2,120,621 is referred to.

Abstract: 673,414. Hydraulic shock - absorbers. McINTYRE, B. D., McINTYRE, W. D., and McINTYRE, C. S., (trading as PATENT DEVELOPMENT CO.). March 14, 1950 [Dec. 17, 1949], No. 6397/50. Class 108(iii) The base compression valve of a hydraulic shockabsorber comprises a body part 37 having a passage 41 controlled by a valve member 47 which has a depending portion 53 providing a passageway for flow from the pressure cylinder 5 to the reservoir 9, a movable valve sleeve member 55 being responsive to fluid pressure acting through a discharge outlet 67 in the passageway. The valve member 47 is lightly loaded by the resilient radial arms 49' of an annular member 49. The depending portion 53 comprises a pin mounted in a central opening in the member 47 and has a bore 65 having a transverse slot forming the outlet 67. A valve sleeve 55 is mounted concentrically with the pin 53 and is held on a seating formed by the underside of the valve member 47, by a spring 59. The valve sleeve 55 is formed with an annular recess 69 adjacent the slot 67 and there is an annular clearance between the sleeve 55 and the pin 53. A disc valve 75 loaded by a weak spring 77, normally closes this clearance. In operation, the disc valve 75 prevents liquid flowing by gravity from the pressure cylinder to the reserve chamber. On compression, the valve 75 opens directly and when sufficient pressure has built up, the valve 55 opens. On rebound liquid flows freely through the large passageway 41 and lifts the lightly loaded valve member 47. In a modification, Fig. 2 (not shown), the valve 75 and spring 77 are omitted so that a continuously-open passage is provided between the pressure cylinder and reserve chamber.

The drive to the member 70 derives from one end of a shaft 44 forming a double-ended output shaft of a gear reduction unit 42 driven from a motor 40 through a drive belt 41. The lever 71 is fixedly connected through a rotatable shaft 72 with a further lever 71 which also carries an arm 68 for connection to the other pivoted plate 64. The other end of the output shaft 44 carries a cam 49 for actuating a timing device 47 having a micro-switch 48 and a cam 43 for engagement with a roller 45 mounted on the base 1 of the apparatus. This latter cam effects the cyclic raising and lowering of the frame F relative to the printing table 2 whilst the timing device 47 controls the energization of the motor 40. The silk screen 38 is mounted in a wooden frame 21 which is loosely held in the frame F through adjustable screw-devices 28, 29 and 33, 32, 18. The sheets to be printed may be held on the table 2 by suction means (not shown). The operation of the machine derives from the automatic timer control of the device 47 on the motor 40 and it allows a period of dwell of the squeegee 57 and the flood bar 60 at both ends of their travel over the screen 38, that is, before the printing-cycle starts again, in order to give the frame F time to lower without forward printing motion of the squeegee 57 and consequent premature delivery of the printing ink through the screen, and also at the end of the printing stroke in order to give the screen time to be raised off the work and give the flood bar 60 time to contact the screen before the bar and squeegee commence their return stroke. The squeegee and flood bar assembly is about halfway through its return stroke before the frame F begins to lower.

Abstract: 608,995. Mercury and other conducting-liquid switches. LAMBERT, H. L. March 4, 1946, No. 6671. [Class 38 (v)] In a centrifugal-switch a tubular-partition 15 extends close to the end of a housing 2 forming a sealed chamber C, the housing being partly filled with a conducting-liquid 6, preferably mercury, and partly by an inert-gas. A .floatmember 17 is slidable in the tube 15 and is normally urged by a spring 18 against the end 5 of the housing. The switch is mounted between spring-arms 3 on a frame 4, 6, 11 radially adjustable on a disc 7, rotation of which confines the liquid 6 to the end 5 of the housing 2 so that it bridges conductors 20, 21, 22. In the event of over-speed, however, the liquid displaces the float 17 so that the liquid level outside the tube falls, thereby breaking connection with the conductor 21, and opening a circuit from supply lines L<1>, L<2> over conductors 20, 21 and collector rings 23, 24 to a driving- motor M. The motor may be switched off at a higher over-speed by closure of a switch 33, thereby establishing a circuit over conductors 20, 22 and collector rings 23, 25. In Fig. 7 (not shown) the float is slidable on a post.

Abstract: 1,133,696. Coated belts. ALBANY FELT CO. 13 Feb., 1967 [21 Feb., 1966], No. 6787/67. Heading B2E. A corrugated belt is made by weaving a base fabric, passing the fabric through a needling machine to cover at least one surface of the fabric with fibres mechanically interlocked therewith, stabilizing the belt in the presence of heat and under tension, and treating the surface of the belt to which the fibres have been interlocked with a high friction natural or synthetic elastomer dispersion. The base fabric may be woven using a creel and spool for feeding each individual warp yarn through constant tension devices to the loom.' The surface to which the fibres are interlocked may be singed and sanded after stabilization to provide a smooth surface. The elastomer dispersion may be applied in such a manner that it penetrates the belt from the surface to between one fifth and one half of the thickness and achieves a high concentration of the elastomer at the surface. The elastomer may be an acrylic polymer, polyurethane, a vinyl polymer or copolymer, synthetic rubber or silicone rubber, or a mixture of two or more of the above polymers, e.g. an acrylic aqueous emulsion having a total solid content in the range of 46 to 50% by wt., a specific gravity of 1.02 to 1.06, a pH of 2.5 to 9.5, and/or a surface tension of 37 to 48 dynes per cm; or a natural gum, resin or rubber. The fibres are mechanically locked into the woven base fabric and extend from at least one side thereof to provide an operational surface which is coated with a high friction natural or synthetic elastomer. The base fabric may be woven of yarns formed from spun fibres which are synthetic e.g. polyester, natural or a blend of synthetic and natural fibres or synthetic filaments. The operational surface may have a coefficient of friction in the range 'of 0.65 to 1.0 as defined by ASTM D 1894-63. The interlocked fibres may be synthetic e.g.. of polyester, natural, or a combination of natural and synthetic fibres.
