Title: Improvements in and relating to power transmission clutches
IPC: F16D41/08
Filed: 1934-06-13
Abstract: 435,148. Clutches. McKENZIE, S. B., 47, Grosvenor Street, Toronto, Canada. June 13, 1934, No. 17554. [Class 80 (ii)] A clutch device comprises oppositelyacting sets of caged wedging rollers l, s, one set l being arranged between cam pockets on a boss c, which is carried on the driving shaft a by a quick - pitch thread i<1>, and the cylindrical inner surface of a flange e on the driven shaft f, and the other set s being arranged between the cylindrical inner surface of a flange d secured to the shaft a and cam pockets on the outer surface of the flange e. A disc w, which is slidable on the shaft f and is connected for rotation with the cage t of the outer set of rollers s by pins y, carries conical projections z adapted to co-operate with conical recesses a<1> in the flange e. With the disc w in the normal position shown in Fig. 1, in which it is held by spring-pressed ball detents g<1>, bidirectional drive is transmitted. If the disc w is moved to the left, by a control lever d<1> through a collar c<1>, the projections z co-operate with the recesses a<1> to turn the cage t so as to render the rollers s inoperative, and the shaft f can now overrun. During overrunning, the boss c moves to the left due to the thread i<1>. The disc w is maintained in its left-hand position by a spring f<1> until the shaft a again takes up the drive, whereupon the boss c screws back to its right-hand position and in so doing moves back the disc w, through pins l<1> slidable in the flange e, to its normal position, restoring bidirectional drive. In a modification, the outer cage t is adapted to be turned through the medium of bell-crank levers pivoted on the flange e and actuated by a conical-ended collar slidable on the shaft f.

Title: Improved means for securing and mounting spiral springs as used with revolving shutters and the like
IPC: E06B9/60
Filed: 1923-07-07
Abstract: 222,936. Hartley, J., and Thornborough, G. R. July 7, 1923. Roller-blinds, spring. - Spring roller shutters, of the kind in which a rotating roller carrying the shutter is mounted upon a divided spindle, one part of which is fixed against rotation and carries within the roller a spring normally acting to counterbalance the weight of the shutter, and in which a second tensioned spring mounted within the roller on the other part of the spindle is normally inoperative but releasable in emergency by hand-controlled, thermostatic, or electrically-operated means to positively raise or lower the shutter, are characterized by a sliding clutch member adapted to clutch the spindle to a fixed bracket or to the roller to put the second spring into or out of action, and by special means for securing the ends of the springs. Fig. 1 shows a roller b mounted on a divided axle a<1>, a<2> and carrying a shutter that is balanced by the concentric springs f. One end of each spring f is secured to the boss g, pinned to the axle part a<1>, while the other ends are secured to the loosely-mounted end boss e<1> of the roller. The additional spring h is connected to the boss i pinned to the axle part a<2>, while the other end is secured to the loosely-mounted end boss e<2> of the roller. When the clutch member j is moved axially against the action of the spring m until it engages the member e<2>, the axle part a<2> and the roller b will rotate in unison, leaving the spring h unaffected during the ordinary use of the shutter. When the operating handle n is released, for example by the rupture of a thermostatic link m<1> in case of fire, or by hand operated or electrical means, the spring m frees the roller from the axle part a<2> and fixes the axle by engagement of the clutch with teeth r<1>, thus allowing the spring h to assist or overcome the springs f as the case may be. To adjust the springs h initially, the bracket n<2> is disconnected from the framework d<2> and the handle and bracket oscillated about the shaft a<2> as a centre. The fixed ratchet r<1> acts as a detent during this process.

Title: Improved method and apparatus for exhibiting images, visible by daylight
IPC: G09F9/30
Filed: 1924-07-26
Abstract: 241,636. Steiner, A. July 26, 1924. Photographs, producing electrically.-Apparatus for producing images visible in daylight comprises insulated conductors bunched together to form a ground on which the image is produced, an electrolytic solution covering the insulators, and means for electrically connecting certain of the conductors so as to produce electrodeposition; the conductors may be selected by optical projection or by means of a stereotype or equivalent plate. As shown in Fig. 1 conductors F consisting of hexagonal graphite prisms, insulated by a covering of asphalt on their contiguous surfaces, are bunched together to constitute one wall of a tank G containing an electrolytic liquid, and selenium cells are provided on the ends of the prisms remote from the tank. The front wall of the tank consists of a glass sheet I provided with silver wire anodes H, and the selenium cells and wires are connected through a reversing switch to a battery &c. A. Selection of the conductors is effected by an optical-projection apparatus J which projects an image of a slide on to the cells, the conductivity of each cell, and thus the rapidity of electrodeposition, varying in accordance with the intensity of the light projected on to it. The image thus produced on the prisms may be destroyed by reversing the direction of the current, and the switch for this purpose may comprise conductors C, connected together and to the cells and wires as shown, and engaged by contacts on a rotatable arm D connected respectively one to each side of the battery. Movement of the arm D from one pair of conductors C to the next reverses the direction of the currents, and the arm and projector may be automatically controlled to exhibit a succession of images. In a modification, Fig. 5, the selenium cells are omitted, and insulated wires 0 are connected to the prisms F and brought together so that their ends form a plane P. A conducting plate Q, having an image photographically formed thereon in insoluble asphalt or otherwise, as shown at Q<1>, is pressed against the plane P to control the deposition, the plate Q and the wires H being connected through a reversing-switch to a battery &c.

Filed: 1958-06-05
Abstract: 895,325. Electric analogue calculating. GENERAL PRECISION Inc. June 5, 1958, No. 18064/58. Class 37. A rate of change of angle voltage # is applied over terminal 10 (Fig. 1) to feed-back integrator U1 whose output (- #) energizes amplifier U3 to drive servometer M coupled to a follow-up potentiometer feeding a balance voltage to the input of U3, together with potentiometers R6 and R9, all rotated through angle #. The ( - #) output is combined in feed-back summation amplifier U2 with the output of nonlinear potentiometer R6 which represents (# - sin 0) for a rotation # of the input shaft, while the output of potentiometer R9 similar to R6 is combined with the output ( - #) in summation amplifier U4. Potentiometer R6 is centretapped to earth and excited so that the slider output is +ve for - ve values of # and vice versa, and the summed inverted output of U2 represents sin #, for # = - 90‹-0-90‹. Similarly the output of U4 represents cos #, for # = 0-90‹-180‹. In a modification (Fig. 3), a rate of angular change signal # is connected directly or over inverting amplifier U12 (as selected by contact d of relay LR) to feed-back integrator U11 whose output representing ( - 8) energizes a servosystem 31 driving a follow-up potentiometer R14 together with a (# - sin #) potentiometer R11 to rotate through angle #. The integrated ( - #) voltage from U11 is combined in summation amplifier U22 with the slider voltage of potentiometer R11 to give a voltage representing sin #. The servomotor also drives cam arm a to contact b at # = 90‹ to operate relay LR and change over contact b to reverse the polarity of the input # voltage whereby integrator U11 and servomotor 31 are caused to operate reversedly. At # = 270‹ arm a engages contact c to return relay LR and contact d to normal so that voltage 6 remains uninverted and integrator U11 and servomotor 31 operate normally. Thus appropriately-poled voltages representing sin # are obtained from amplifier U22 for an unlimited range of # (Fig. 2, not shown). The apparatus is capable of generating a wide range of other continuous non-linear functions of variables.
