Title: Improvements relating to rheostatic braking of electrically propelled vehicles
IPC: B60L7/00
Filed: 1930-02-28
Abstract: 347,381. Control of D.C. motors. JOHNSON, C., 9, Stanmore Avenue, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London. Feb. 28, 1930, No. 6714. [Class 38 (iii).] Non-regenerative braking ; reversing.- A tramcar is provided with two groups of motors, the armatures of the two motors in each group being permanently connected inseries. In the " forward " position of the controller at one end of the vehicle the motors are arranged as shown in Fig. 1, the field Fl being that of the armature A<1>, and the others likewise. In the " backward" position of this controller each pair of armatures is reversed as a whole. In the " braking" position, Fig. 2, each pair of armatures is reversed as a whole and substituted for the other pair, an equalising connection E and braking resistance R being added to the circuit. This gives a cross-connected fieldarmature system that will have a braking effect whichever direction the tramcar runs and the equalizing connection E ensures that should a disconnection occur in any one circuit, there is still a braking effect for each direction. The controller at the other end of the tramcar gives the connections shown in Fig. 4 when in its " forward " position, and interchanges the groups of armatures in the same sequence as the first-mentioned controller in its " backward " and " braking " positions, with the result that in the " braking " positions of either controller, each armature is associated with the same cross-connected field.

Reel and endless-web apparatus.-A device for displaying advertisements on endless bands for optical projection effects rapid movement of the band to change the advertisement, with comparatively long intervals of rest between each movement. Fig. 3 shows a film 40 fed by constantly rotating geared rollers 3, 4 and drawn step by step across a projection window 6 by an intermittently rotated drum 2, against which the film is held by rollers 44 and a pivoted member 43. The drum 2 is moved by a spring- retracted rod 20 raised and allowed to fall by a constantly rotating cam 25, the rod 20 acting through a link 27 moving a lever 28 carrying a pawl 29 operate a ratchet-wheel 30 fixed on the drum shaft 7. For the purpose of exact location of the film 40 in the window 6, the distance through which the wheel 30 is turned at each step is limited by another ratchet-wheel 33 with teeth disposed in the direction opposite to that of the teeth on the wheel 30. The wheel 33 is mounted loosely on the shaft 7 within the limits allowed by one or more studs 34 on the wheel 30 engaging slots 35 in the wheel 33. A spring- pressed pawl 37 acts as the limiting stop for the wheels 33 and 30, and is subsequently raised by the pressure of a nose 39 on the cam 25. This allows the wheel 33 to move forward a short distance under the action of a spring 36, thus preventing the pawl 37 falling back to its original place after the nose 39 has passed. The wheel 30 is held against return by a pawl 31. The device may be mounted in show rooms or shop windows, or on a vehicle, and may be actuated in this case by any of the moving parts.

IPC: B31D1/02
Filed: 1924-03-18
Abstract: 220,252. Swift, G. W. March 18, 1924. Envelopes and the making.-In machines for attaching strings to envelope flaps &c. by looping the string about an eyelet before this is secured to the flap, the string is formed into a loose loop while the looper is approaching the eyeleting position, and after reaching this position the free end of the loop is gripped and the looper retires and tightens the loop around an eyelet, which is then upset to secure the string to the flap. The looper is carried at the end of an arm 1 adapted to be rocked on a shaft 2 by a link 77 and a crank on the driving-shaft 80. The string a passes through a passage 7 in the looper and then from the front to the back of a spring blade 8 through a notch 10, then through an eye 16 serving to hold it clear of a finger 23 which is rotated by a pinion 22 to lay a loop around a conoidal disc 24. This disc is pressed against the disc 20 that carries the looping-finger 23 by a blade spring 27 so that it can yield to release the formed loop. The looping-finger is rotated in one direction only by a toothed wheel 39 operated through a one-way clutch 49 by a toothed wheel 47 running on a fixed toothed sector 53 when the looper arm is rocked. A gripper 141, 142, operated by a cam on the shaft 80, holds the end of the loop when it is brought into the eyeleting position and while dies 95, 110 punch out the strengthening-washers from tapes and upset the eyelet presented by the carrier 121. A radial recess 30 in the looping- discs and in the pinion 22 enables the looper to retire from the eyeleting-plunger and during its retirement the length of the string to remain attached to the loop runs through the looper and is cut off between the looper and the eyeleting- device.
