Title: Improvements in road traffic signals intended particularly for use on motor cars
IPC: B60Q1/34
Filed: 1930-05-14
Abstract: 355,659. Road-traffic signals on vehicles. TAYLOR, E. C., 7, Rosedale Road, Colonial Heights, Yonkers, New York, U.S.A. May 14, 1930, No. 14863. [Classes 40 (i) and 118 (ii).] A traffic signal intended particularly for use at the rear of a motor car has an illuminated field for displaying two words or indications such as SLOW and STOP, having a letter or part, the L in the former and the T in the latter, peculiar to each and in the same letter space in the display field, and a source of light for each, baffles being provided to prevent the light illuminating each word or indication from illuminating the peculiar letter or part of the other word or indication. A stencil plate 26 behind a translucent coloured front is illuminated at will or by the movement of the steering mechanism or the brake or clutch pedal by lamps 11, 11a behind differently coloured transparent sheets 62, 61. Baffles 52, 52b screen the cut-outs 49, 49a in the stencil plate and baffles 60, 60b screen the letter P when the lamp 11 is lit to display the indication SLO, and baffles 53, 54, 52a screen the cut-outs 46, 48 when the lamp 11a is lit to display the word STOP, a slot 60c in the baffle 60b allowing light to pass to the letter P through a coloured transparent plate at the back of it. Further baffles near the screens 61, 62 restrict reflected light. The direction signs 38, 39 below the words or indications in the stencil plate are illuminated by further lamps 16, 16a behind coloured transparent plates 67, 68 so arranged that the shaft of the arrow sign is illuminated at will with and in the same colour as one of the arrow heads. A lamp 19 below the compartment containing the coloured plates 67, 68 illuminates the licence plate, and a parking light lens shows a coloured light when any one of the lamps is lit. The rear signal device may be connected to and operated simultaneously with a similar front signal device, in which the letter indications of the rear sign are dispensed with, the upper aperture being wholly illuminated in the same colour as in the rear sign. A tell-tale at the back of the front sign is illuminated in colour simultaneously with the front of the sign.

Title: Improvements in central buffing and draw gear for railway vehicles
IPC: B61G9/06
Filed: 1929-05-14
Abstract: 335,168. Whitmore, R. L., and Spencer Moulton &. Co., Ltd., G. May 14, 1929. Combined buffer and drawgear. - Relates to central buffing and draw-gear for railway vehicles of the kind wherein the buffing and draw springs are embraced by a yoke 1 which, by a cotter and slot connection 5, 6 with the coupler-head shank 2, is pulled outwardly when drawing and relatively to which the couplerhead and shank can move inwardly when buffing. According to the invention the springs located within the yoke are adapted to be compressed between .abutments and movable compression plates, one or more of which is provided with an extended stem or stems whereby compression of the springs in parallel is obtained as required. In the construction shown in Fig. 2, two abutments 21, 22 are secured to a housing 7 containing three springs 15, 18 and 12, which are disposed between a front follower plate 16, movable compression plates 17, 19, 20, 14, and the closed end 13 of the housing, the plates 19 having stems 23, 24 projecting on either side thereof. In buffing the elements 16, 19 and 14 are moved inwardly to compress the springs against the elements 17, 20 and 13, while in drawing the function of all these elements is reversed. The springs employed are preferably of the compound metal and rubber type, and additional springs may be disposed between the closed end 13 of the housing and the rear 11 of the yoke, and between the yoke and the underframe. The abutments 21, 22 are preferably constituted by cotters secured to the sides of the housing 7 as shown in Fig. 4, with or without upper and lower stops 26, or abutments in the force of spring rings may be provided, while in a modification the housing 7 is omitted and the abutments are attached to the yoke 1. In the construction illustrated in Fig. 7, the housing 7 is built up of a number of sections having inwardly projecting flanges 34 at their rear ends to form compression plates 35 furnished with integral stems 36. In this arrangement compression of the springs in parallel takes place either in buffing or in drawing, but the sections may be initially spaced a slight distance apart and the stems 36 shortened so that the parallel compression is preceded by a series compression. In a further modification, Fig. 13, shortening of the stems 23a, 24a of the plates 19, 14 is arranged to allow the springs 15, 18, 12 to be compressed singly and then in parallel. In another modification only two springs are employed, these being of oval crosssection, and the housing 7 may be shortened to contain only one of the springs. Specification 183,018 is referred to.
Patent GB-586167-A (GB)
Title: Tunable ultra-high-frequency apparatus
IPC: H03J3/28
Filed: 1944-08-08
Abstract: 586,167. Electric resonators. HAZELTINE CORPORATION. Aug. 8, 1944, No. 15100. Convention date, Sept. 25, 1943. [Class 40 (iii)] Two sections of transmission line, which may either be #/4 and #/2 long respectively, or be tuned to different frequencies, are tuned by the same displacement of a tuning bridge, and one of the sections is dielectrically loaded so that its frequency may bear a constant relation to that of the other throughout the range of tuning. In a Hartley oscillator, Fig. 1, the upper resonator 12, 13 is connected at one end between the control grid and anode of a valve 10 and is short-circuited at a distance #/4 from the valve by the capacitance between plates 14, 15. These plates are separated by a mica strip 17 and are mounted in a yoke 16 made of thermoplastic resin or the like, so that tuning can be effected by turning the screw 33. The lower resonator 21, 22 is connected to the cathode of the valve and is tuned by a similar short-circuiting capacitance 23, 24, 25, but in order that its electrical length may be extended to #/2 it is immersed in a fluid dielectric, such as castor oil, in a container 30. It is grounded to the container through a brush 29. The residual lengths of the resonant sections, beyond the short-circuits, are detuned by condensers 18, 28. To allow for the difference between the terminating impedances at the valve end (viz. the interelectrode impedance Cgp and the impedance of the cathode) the short-circuits are spaced apart by means of an adjustable member 26, or alternatively compensation may be effected by shunting the open end of the line 21, 22 with a suitable impedance. The cathode-heating battery A, anode battery B and grid leak 32 are connected to the valve through the resonant sections. Instead of the liquid dielectric,. capacitors uniformly spaced along the line 21, 22 may be used for loading it, Fig. 3 (not shown). The frequencies of the two resonators may be equal, as in the oscillator shown in Fig. 1, or be separated by a constant difference. The Lecher lines may be replaced by coaxial lines of which one contains a liquid dielectric such as oil. The short-circuited sections may be replaced by open-circuited sections of appropriate length.

Title: A snap action mechanism especially for electrical switching devices
IPC: H01H5/04
Filed: 1965-04-09
Abstract: 1,097,429. Snap action mechanisms. SVENSKA ELFABRIKS A.B. SELFA. April 9, 1965 [April 24, 1964], No. 15103/65. Heading H2B. [Also in Division F2]. A snap acting actuating mechanism comprises a rotatable shaft 1 carrying a plate 2; a rectilinearly movable member 17 for actuating the contacts of a switch &c. (Figs. 4-7, not shown); a means for transmitting motion between the plate 2 and member 17 and consisting of a linkage 21, 23 and an overcentre spring 4 whose ends are anchored respectively on the plate 2 and one link 21; and a pair of locking links 14, 19 actuated by the plate 2 and co-operating with fixed stops 18, 25 to lock the member 17 in each end position respectively. As plate 2 is rotated to bring point 3 towards the dead centre position a pin 24 slides in a slot 6 in the plate; just before dead centre the end of slot 6 lifts the link 19 away from stop 25 freeing the member 17. Further rotation causes the end of a second slot 5 to drive the other link 14 towards its stop 18; this positively moves the member 17 upwards and through link 23 rotates link 21 thus preventing the mechanism stopping in the dead centre position. As the spring passes over centre links 21, 23 are driven rapidly upwards to bring member 17 to its other end position. The spring also drives the plate 2 clockwise so that slot 5 drives the link 14 overcentre against stop 18 to lock the member 17.

Title: Slicing machine
IPC: B26D1/553
Filed: 1925-06-13
Abstract: 251,132. Schor, J., and Eldridge, J. June 13, 1925. Stream-cutting machines.-Comprises a special mounting for the cutting-wire and a general arrangement of parts forming a slicing-machine of the type in which the material is placed in a trough provided with a revolvuble shaft carrying a cutting wire and controlling an intermittent feed by its rotation. A V-shaped trough 1 is furnished with bearings which on one side carry a feed screw 47 and on the other side a shaft 13 for carrying the rotating cutting-wire 19. The cutting-wire is tensioned between an arm 17 carried by the shaft 13, and a loose pinion 21 and is rotated positively at both ends. Thus rotation of the crank 14 rotates the arm 17 directly, while gearing operated from the pinion 29 rotates the pinion 21 at the same speed as the arm 17. The shaft 13 also carries a slice-holder 18 which can be fixed adjacent to and in alignment with the end of the trough as shown in Fig. 2 or be allowed to swing down into the inoperative position shown in dotted lines in Fig. 1. A spring pin 24 fixes the holder in either position. A movable plate 41, which can be engaged with or disengaged from the feed screw 47 by operating the spring pawl 44, is used to push the material towards the cutting wire. The feed screw is geared to a toothed wheel 53 to which a feed motion is communicated by the pawl 57 carried by the swinging arm 56 operated by an eccentric on the shaft 13. To vary the feed, a gauge plate is rotated to engage the end of the pawl and lift it during part of its swing, thus varying the time of its effective engagement with the wheel 53. When the machine is used for cutting butter, a die is used with tensioned cross wires 78, Fig. 4, while for cutting cheese the wires usually are omitted. The dies have three slots to fit over screws 71 at the end of the feed trough. The cross wires are tensioned by fixing one end at 76 and making the other end adjustable axially by screw-and-nut mechanism. The fixed ends are passed into a recess in a fixed pin and are kinked by a lateral screw.

Abstract: 971,430. Tentering fabrics; corrugating sheet material. G. MOHRING. April 18, 1963 [April 19, 1962], No. 15392/63. Heading D1S. Undulations formed in a fabric web 3 prior to tentering are brushed on to the pin bars 6 of a tenter chain 1 and are held down thereon beyond the brushing-on region. The web 3 is fed at a speed exceeding that of the chain 1 on to a corrugated band 2 and a roller 4 encircled by a ring of foam rubber or foam plastic presses the edge of the web 3 into the troughs of the band 2. A brush roller 5 mounted on a shaft 14 coaxially with the roller 4 brushes the edges of the web 3 on to the pin bars 6. In one embodiment, Figs. 1 and 2, a fixed bar 7 of round or flat cross-section and having upwardly curved ends is disposed between the rollers 4, 5 so that the web 3 cannot be lifted off the pins by the brush. In an alternative embodiment, Fig. 3, the web 3 is held on the pins by a continuously-moving endless band 8 passing around a pulley 9 on the shaft 14 and disposed between the rollers 4, 5 and around a small return roller 10. In a further embodiment, Figs. 6 and 7, a thin annular disc 11 is coupled to rotate with the rollers 4, 5 by pins 13 extending through two diametrically opposite slots 12. The disc 11 has a concentric opening therein and rides on an eccentric disc 16 keyed to the shaft 14 on which the rollers 4, 5 are freely mounted so as to be rotatable relative thereto, the roller 4 being driven by the band 3. The disc 16 is adjusted so that the periphery of the disc 11 projects the maximum amount in the region shown. In a still further embodiment (not shown) the rollers 4, 5 are replaced by a single roller encircled by a brush. The bar 7 may be disposed in a peripheral groove in the brush.

Title: Improvements in and relating to the construction and manufacture of built-up metal wheels
IPC: B60B1/00
Filed: 1935-05-27
Abstract: 457,393. Toothed gear-wheels. ROBSON, P. W., Three Oaks, Horsell Common, Woking, Surrey. May 27, 1935, No. 15428. [Class 80 (i)] [See also Group XXXIV] A built-up wheel comprises a thick rim and a system of chordal spokes of rolled sections with webs or flanges at right-angles, such as angle bars, T-section bars, and the like, embracing a polygonal boss. The spokes cross as seen axially of the wheel, and each spoke passes in one or more lengths with at most a slight set in a plane at right-angles to the wheel from one point of attachment on the rim to another, an intermediate part of a web or flange of each spoke landing on a face of the boss. In the form shown in Figs. 1 and 2, a thick rolled rim A is shrunk on to a pair of T-section rings 2a. The boss comprises three steel slabs 3 spigotted together and held in position by plates 5 secured by tap-bolts 6. A set of three spokes 8, 11, 12 with slightly offset centre-portions are arranged on alternate faces of the boss and secured at their ends to one face of a ring 2a. A similar set of spokes 9, 13, 14 is arranged reversely to the first set and secured to the opposite face of the ring 2a. Where the spokes cross they are secured by rivets 15 passing through spacing plates 10. The spokes and rings 2a may be of channel or other rolled section. In a modification, slightlycurved spokes co-operate with the slightlyconcaved surfaces of the boss. In a further form the pair of spokes 13, Fig. 2, is replaced by a single wide channel section spoke, and the other set of spokes are divided into three lengths united to the continuous spokes by gusset plates. A split wheel embodying the invention is described. In a further modification, each spoke is divided at one point of trisection, and a set of six spokes of two-thirds the full length engages each surface of the boss. The remaining thirds of the spokes form a reversely disposed set united to the first set by riveted gusset plates. The rims may be provided with double-helical teeth, or, when used for vehicles, with projections to facilitate adhesion.

Title: Improvements in wagon tipplers
IPC: B65G67/00
Filed: 1939-05-24
Abstract: 529,656. Rotary tipplers. BABCOCK & WILCOX, Ltd., and WRIGHT, R. B. May 24, 1939, No. 15448. [Class 78 (iv)] The means for rotating a rotary tippler to the tipping position initially applies the top clamps to secure the vehicle to the tippler, before the actual rotation for tipping commences. Fig. 1 shows a platform 1 tipping about the axis 3 and carrying a truck-receiving table 5 pivoted thereto at 4. The initial pull on the ropes 20 wound up by drums 23 swings the lever system 12 about the pivot 13 against the action of the counterweights 14, until abutments 15, 16 contact the top edges of the sides of the truck. Pivotal movement about the axis 19 ensures that both members 15, 16 bear evenly on the truck sides. Additional winding of the ropes 20 then tips the truck by moving the platform about the axis 3. During the initial tilt of the platform the raised table 5 overbalances and tips the truck against a side buffer 2. During this latter movement the members 15, 16 slide along the bar that supports them so that they remain in contact with the truck. Fig. 9 shows the operating cables 78 passing from fixed points 79 on the rings of the frames round pulleys 80 on levers 62 pivoted at 63 so that the initial pull swings these levers against the action of the counterweights 71 and so lowers the bars 74 so that the members 75, 76 on each bar contact the top edge of the truck.

Filed: 1919-06-19
Abstract: 151,341. Carrington, J. H., and Young, W. B., (trading as Carrington Optical Machinery Co.). June 19, 1919. Drilling-machines.-In a drilling machine of the kind in which the work carriage is angularly adjustable on a plane transverse to the axis of the drill, particularly a bench machine for drilling eyeglass lenses, the work is held by two separately and relatively movable parts, one consisting of a work-supporting plate and the other of angularly movable prongs to engage the work and tilt it relatively to the plate. The work is held between a pair of pins 19<a> on a plate 19 and a pair of forked prongs 20 in a casing 24, the casing and plate being mounted in guides 21 on a frame 22 and being connected together by a spring 28, so as to be normally in contact with a stop 29. The prongs are mounted on a cross-bar 23 and pressed down by a spring 25 and are adjusted to vary the inclination of the lens with respect to the axis of the drill by a screw 26, co-operating with a pointer 27. The frame 22 is mounted on a pin 31 in the carriage holder 30 and is angularly adjustable and locked in position by a spring trigger 32, engaging notches on the arcuate edge 34 of the holder, the angular position being indicated by a pointer 33 and scale 36. The edge of the lens is positioned by a screw gauge-stop 42 provided with a graduated head 43 co-operating with a pointer 44 and retained in adjusted position by a spring plunger 48. The holder has a hole 37 so that it may be mounted on a centre pin projecting from the machine bed, to which it is secured by a stud 39 and block 40, Fig. 6. The bed has an upstanding peripheral flange 5<a> to prevent escape of oil, and is provided with holes for draining off the accumulating oil, which is collected in a well 45. The drill spindle 4 is driven by a belt passing over pulleys 6, 7 and is fed down by a hand lever 9 controlled by a spring 16 and having rollers engaging between collars 12 on the spindle, the lower one of which is adjustable for wear. The depth of feed is determined by a projection 13 engaging a screw stop 14 clamped in position by a nut 18. An auxiliary drilling attachment 49 may be mounted on the spindle of the pulleys 6.
