IPC: F02M7/14
Filed: 1927-10-13
Abstract: 303,924. Boonzaier, G. J. Oct. 13, 1927. Spray-carburettors. - The fuel needle-valve is actuated from the throttle valve through the medium of a cam having a flexible and adjustable blade profile, the blade being mounted on a base-plate provided with means for local flexing of the blade to vary the rate of throw, the baseplate being adjustable as a whole to varv the total throw. A variable air aperture concentric with the nozzle is produced by an iris diaphragm or geared shutters which may also he actuated from the throttle valve and, at times, independently thereof. The body A has a flange A<1> for connection to the intake manifold, and a single air inlet A<4> in which is a nozzle A<2> fed from an annular float chamber B. The iris diaphragm D is actuated through a spider D<1> and a metal tube O to which an arm N is secured. This arm is associated with the main throttle lever L through a ball joint N<1> and a spring-loaded sliding member M<1> provided with a stop pin M<3>. The arm N may be actuated independently of the throttle valve by a separate rod to decrease the area around the nozzle at starting. Upon release of the rod, the pin M<3> is drawn back against the lever L for simultaneous actuation of the throttle, diaphragm and needle valve. The nozzle aperture is regulated bv a needle, valve F which passes axially through the tube O and is threaded through a pinion G, the valve being prevented from rotating by its square upper end sliding through a guide P. The pinion G is rotated by a toothed quadrant H pivoted on a stud H<3> and carrying at its other end a swivelling washer H<2>, a slot in which is engaged by the blade K<1> of a cam mounted in a baseplate K which is adjustably secured to the cranked end L<1> of the throttle spindle by a bolt L<3>. The blade can be flexed between its extremities K<3>, Fig. 1, by means of set-screws K<2> and the total throw of the cam can be varied by releasing the bolt L<3> and tilting the baseplate. The washer H<2> is retained in position by a plate H<1> held by the stud H<3>. The cam may act on the needle valve either directly or through other mechanism. Minor adjustments of the level in the float chamber may be effected by a screw B<3> which loads the float through a spring B<4> and flanged tickler B<2>. In a modification, the iris diaphragm is replaced by a pair of geared metal shutters, Figs. 3 and 6 (not shown).

Title: An improvements relating to electrical stop motions
Inventor: SHORTLAND ARTHUR
IPC: D04B35/10
Filed: 1955-09-27
Abstract: 801,785. Knitting-machines. MELLOR BROMLEY & CO., Ltd. Nov. 28, 1956 [Sept. 27, 1955], No. 27476/55. Drawings to Specification. Class 74 (2). A circular knitting-machine in which more than one yarn is fed at a single feeder has a stop motion switch associated with each yarn and the switches are connected in series in the stop motion circuit. This arrangement avoids operation of the stop motion unless each switch is closed resulting from an abnormal condition arising during the feeding of one or more yarns and permits yarn changes to be made without operating the stop motion. The switches may be in the form of wheels rotated by the running yarns so as to cause balls enclosed in slots in the wheel to be urged under centrifugal force out of contact with a ring connected to a lead of an electrical circuit. Upon undue slackness or failure of a yarn which is being fed to the needles, the wheel slows down or stops such that the balls drop on to the ring and complete the circuit to effect stoppage of the machine. Alternatively, droppers may be used for the switches. Specification 795,687 is referred to.
Patent GB-536330-A (GB)
Title: An improved means for trimming shaped grinding wheels
IPC: B24B53/07
Filed: 1939-10-09
Abstract: 536,330. Trueing grinding-wheels. WICKMAN, A. C. Oct. 9, 1939, No. 27516. [Class 60] Apparatus for trimming a helically grooved grinding-wheel b comprises a rotary crushing- roller a movable on compound slides both axially and transversely of the grinding-wheel, the axial slide being actuated through movable mechanism controlled by a clutch and arranged to cause the roller to pass automatically through successive operation cycles. The rollers a which may be of V or multiple V form corresponding to the wheel profile is freely rotatable on a transverse slide c which in turn is mounted on a longitudinal slide d. The transverse movement is effected by a hydraulic cylinder f fed by lines g, h. The longitudinal movement is effected by a screw u driven either from the motor m which drives the grinding-wheel by the belts l or, as shown, by a separate electric motor o which drives both the grinding wheel and the slide d during the trimming operation only. For this purpose the motor o drives a shaft p connectable to the grinding-wheel spindle by a one-tooth coupling 25, 26 and gearing. From the shaft p interconnected shafts s, t, u and change gearing 5 drive the screw i for its feed movement. A high-speed drive 7 is used for the quick return movement, the reversal being effected by a clutch 11 operable by a pair of coaxial hydraulic plungers 14, 15 and rack and sector gearing 21. A slider 32 carrying stop collars is moved in opposite directions by a tappet 36 on the longitudinal slide thus causing a tappet 31 to actuate the valve 30 controlling the supply to the reversing clutch and the cross slide. During the trimming cycle the grinding- wheel is driven slowly from the motor o and the tool is traversed by the slide d. At the end of the travel the valve 30 is actuated to withdraw the transverse slide and reverse the movement of the slide d. At the end of the return the valve 30 is actuated to move up the traverse slide and impart the slow forward feed to the slide d. The slide d may be carried on a third slide k which is movable with the operating mechanism transversely of the grinding wheel. The slide k is then carried on a transverse slide 40 which also carries the grinding wheel b and is movable over the bed on rollers 41. The slide k is movable by a screw 43 driven from a hand wheel 48 through a shaft 46 and gears 45. Another hand wheel 51 drives a screw 49 running in a nut 52 carried by a bearing 53 actuated by hydraulic cylinder 57 to move the slide 40 and all the parts carried thereby away from the grinding-wheel. Rotation of the hand wheel 51 drives the screw 49 and effects adjustment of the lowermost slide 40. Rotation of the wheel 48 drives the shaft 46 and gears 45 and 'also through gears 54, the nut 52. This moves the slide k over the slide 40 and also moves the slide 40 equally over the bed. The hand wheel movements thus serve to adjust the trimming-roller and grinding-wheel relatively to each other and to the work.

Title: Improvements in or relating to direction indicator devices for motor vehicles
IPC: B60Q1/42
Filed: 1950-11-13
Abstract: 682,643. Road-traffic signals on vehicles. GENERAL MOTORS CORPORATION. Nov. 13, 1950 [Dec. 7, 1949], No. 27611/50. Class 118 (ii). A vehicle direction indicator control device comprises switch mechanism adapted to fit onto the steering column and having a manually operable lever which is returned to its neutral position by the reverse rotation of the steering wheel acting through a friction roller comprising a hub with a ring: of frictional material on it. A housing 2 is attached to the steering column 4 by means of an integral split ring clamp 8, 10, and bolt 14, and contains a plate 46 pivoted in a slot 48 and carrying a pin 44 having rotatably mounted thereon a friction roller 30 with axially extending bushing 34. A manual control :lever 16 is pivoted on a bolt 26 which also secures a cover 28 for the housing 2, and carries at its inner end a cam plate 50 with which the bushing 34 engages under 'stress of a spring 54 pulling on the plate 46. An operating member 60 of a special switch 64 enters a slot 62 in the lever 16 and is moved to its left or right switching positions by the appropriate movement of the control lever, which movement causes the cam plate 50 to force the friction roller 30 into contact with the hub, of the steering wheel 6. Rotation of the steering wheel in the direction of the turn rotates the friction roller 30 and hence bushing 34, but, as the lever is already at its limit of movement, slip occurs between the bushing and cam plate. On reverse rotation of the steering wheel the frictional engagement between bushing 34 and cam plate 50 causes the latter (and hence lever 16 and switch 64) to be returned to the neutral position. The construction of switch 64 is described in detail with reference to Figs. 2a and 3 (not shown) and a flashing light direction indicating system using the invention is described having the circuit of Fig. 4 (not shown). Facility for a brakeoperated stoplight is included, also a pilot light which flashes when a direction signal is operative, and which may be mounted in the socket 80 within the housing cap 28.

Title: Apparatus for automatically indicating the passage of ships through channels or straits
IPC: B63B45/08
Filed: 1923-11-05
Abstract: 206,835. M³ller, D., and Thirring, H. Nov. 11, 1922, [Convention date]. Light, control of signalling apparatus by.-In alarm apparatus employing light-ensitive cells, preferably of the selenium type, for indicating the passage of a ship through a channel, a beam of light projected across the channel is intermitted at audio-frequency in order to produce a superimposed alternating current on the direct current through the cell, the alternating current being utilized for actuating alarm or indicating apparatus. Operation of the alarm apparatus due to the slow variation of the resistance of the cell is thus prevented. The alternating component of the current through the cell is sieved out by transformers or thermionic apparatus and then amplified and rectified. The rectified current normally renders a direct current relay inoperative, but when the beam of light is intercepted, the current ceases and the relay closes the circuit of the alarm or indicating apparatus. Increased sensibility is obtained by tuning the receiver circuit to the frequency of the source of light. The Specification as open to inspection under Sect. 91 (3) (a) states that an alarm may be given by the passage of a person through the beam of light. This subject-matter does not appear in the Specification as accepted.
