Title: Improvements in electric piston motors
IPC: H02K33/12
Filed: 1928-04-05
Abstract: 320,097. Frenell, P. April 5, 1928. Reciprocating machines; commutators.-A reciprocating electric motor particularly for driving pumps, tools, &c. has one or more coils to produce a pulsating magnetic field and a plunger adapted to be reciprocated by the field, the coils being energized through a, commutator or other switch in such a way that condensers are connected in series therewith when current is supplied from the source. In one form, Fig. 1, two coils 12, 13 are connected as shown by fixed brushes 3, 4 to a rotary commutator 1 driven by a motor 2 the speed of which may be controlled by a rheostat 5, and the connecting point 20 of the two coils is connected through a condenser 11 to a third fixed brush 6 bearing upon the commutator. In the position shown, the coil 13 is energized in series with the condenser. When the commutator has rotated through 180‹ the condenser is discharged, coil 12 is excited and the plunger 14 moves upwards. In a modification, (Figs. 3 and 4, not shown) four magnet coils are provided and the commutator is divided into four parts and has four stationary brushes, the coils being energized in pairs. Fig. 5 shows a form using a single coil 24 through which current flows alternately in opposite directions. Fig. 11 shows a simplification of the commutator of the last form whereby the coil is alternately energized in opposite directions from the source and by the discharge current of the condenser. A modified commutator, Fig. 7, suitable for use with the wiring shown in Fig. 1, alternately connects the coil 13 to the source through the condenser and the coil 12 across the condenser. With this arrangement the coil 12 is never connected to the source. A weaker return stroke may be obtained by increasing the resistance in the circuit of the coil 12. The same connections may be effected by a simplified commutator, as shown in Fig. 9. Fig. 13 shows a form similar to Fig. 1 for use when a weaker return stroke is required. The magnet coil 12 for the return stroke is made smaller than the coil 13 for the forward stroke and a separate condenser 11, 11<a> is provided for each coil. The commutator is shown developed and the connections are such that if the commutator is rotated downwards, four circuits will be established in one revolution, viz., at tha angular positions 45‹, 135‹, 225‹ and 315‹. In the positions 450‹ and 225‹ coil 12 is connected to the source in series with condenser 11, in the positions 135‹ and 315‹, coil 13 is energized in series with condenser 11<a>. In another modification the commutator contacts are so connected that at the position 45‹, coil 12 is connected across the condenser 11, at 135‹, coil 13 is connected to the source in series with condenser 11<a>, at 225‹, coil 12 is connected to the source in series with condenser 11, and at 315‹, coil 13 is connected across condenser 11<a>. The commutator may be replaced by a double-throw switch. The magnet coils may be energized from an alternating-current supply in which case the motor 2 is a synchronous motor.

Patent GB-939427-A (GB)
Title: Improvements in disc brakes
Inventor: BUTLER HENRY JAMES
IPC: F16D55/2255
Filed: 1959-04-01
Abstract: 939,427. Disc brakes. DUNLOP RUBBER CO. Ltd. March 17, 1960 [April 1, 1959], No. 10964/59. Class 103 (1). A disc brake comprises a rotatable disc, a pair of angularly movable pressure-plates fixed to spindles which are rotatably mounted in a housing straddling the periphery of the disc, the pressure plates being disposed on opposite sides of the disc and carrying friction pads for engagement with the disc, means for moving the pressure plates simultaneously to apply the brake, retraction members comprising bushes which are maintained by springs with an interference fit on tapering portions of the spindles, and arms which extend from the bushes which are capable of moving with the spindles for a predetermined distance only on application of the brake and spring means for returning the arms and thereby retracting the pressure-plates to a predetermined distance from the disc. In the embodiment illustrated in Figs. 3 and 4 the disc brake is operated by angular movement of the lever 16 pivoted at 17 to one pressure-plate 14 fixed to a spindle 15 journalled in caliper ends 12. Angular movement of lever 16 is effected either by mechanical means secured to aperture 19 or by admission of fluid under pressure to cylinder 20 and at the same time acting through rod 26 to actuate the opposite pressure-plate 14 and urge it towards the disc, thereby effecting a balanced frictional engagement between the friction pads 55 and the disc. On removing the braking force the lever 16 is returned to its inoperative position by the spring 35. As the pressure-plates 14 pivot to apply the brake so the spindles 15 on which they are mounted rotate and a spring-loaded bush 37 provided with an integral arm 39 is similarly rotated to an extent determined by the clearance between a hole 47 in the arm 39 and a pin 48 carried by the fixed caliper housing end 12. The clearance is overcome on applying the brake and a light wire spring 49 between the arm 39 and the caliper moves the arm back to provide brake pad clearance. If pad wear occurs, the bush 37 will slip on the tapered portion 36 of the spindle. Brake adjustment is provided in the form of a rod 26 having a head 27 and a nut 29 at its opposite ends which bear against the outer surface of the one pressure-plate 14 and the outer surface of the lever 16, respectively. The nut 29 is adjustable by means of a torsion-spring 33 which is connected between the nut and the lever to take up the clearance resulting from wear of the friction pads.

Title: Apparatus for Conveying Bottles or like articles
Inventor: ELLIOTT VICTOR GERALD
IPC: B65G47/71
Filed: 1967-03-08
Abstract: 1,193,852. Empty bottle disposal; conveyers. V. G. ELLIOTT. 4 April, 1968 [8 March, 1967], No. 10981/67. Headings B8A and B8S. In a public house, empty bottles are dropped down shoot 100 and fall into four shoots in apparatus I supported by plate 15. When four bottles rest on plate 15, contacts are made and solenoid 20 operates to withdraw plate 15 and the bottles fall into catcher 30 which descends to drop the four bottles into crate 3 gently, to form a row therein. The crate 3 is pushed forward by pusher 61 a distance of one row to receive the next four bottles. When the case 3 is full it is discharged to the right by pusher 61 while stop 84 is depressed to permit this rightward movement. A second empty case then slides beneath apparatus 1 from the left, being released by stops 53. The cases travel on rollers. Shoot 100 (Fig. 3).-As the bottles fall down the shoot 100 they are guided alternately left and right by a dolly 4 pivoted at 5 and influenced at 8. They thus form two streams of bottles which are respectively divided in two by dollies 4a and 4b (which are magnetically attracted at 10a and 10b and gravity influenced at 4a and 4b) to form four streams of bottles. Stops 53 (Fig. 1).-The four levers 53 are pivoted at 54 and carried by pusher 50 and caused to pivot by solenoid 58 so that crate 3 sliding down rollers 52 is checked by being lifted off the rollers 52 by the levers 53. A crate is released by the opposite movement of the levers 53. Pusher 61 and stop 80 (Fig. 1).-Pusher 61 has bars 65 pivoted on bar 61 and is operated by solenoid 70 and spring 71. Stop 80 has bars 84 which slide vertically up and down when bar 91 is moved left and right. Pusher 61 and stop 80 are coupled together by cam 64 of the pusher which engages pin 94 of bar 91 so that when solenoid 70 is operated the pusher 61 slides leftward beneath the crate 3 and then moves rightwards to move it one step forward, the first bar 84 being lowered at the same time so that the crate has now advanced one step and is held by the second bar 84. When solenoid 70 operates again the second bar 65 operates to push the crate 3 forward and the second bar 84 is lowered so that the crate now has advanced two steps into position against the third bar 84. In this way the case is advanced one step forward each time to receive a row of bottles till it is filled.
