Title: Improvements in, and connected with, Clutches
Inventor: BRADLEY EDWARD FRANKLIN
Filed: 1903-03-14
Granted: 1904-01-14
Abstract: 5988. Bradley, E. F., and Edmunds, H. March 14. Clutches.-Relates to modifications in the clutches described in Specification No. 18,170, A.D. 1902, for motor cars &c., and consists in mechanism for pushing off the clutch rings in groups. The inner set of rings d and rods i<2> correspond with those described m the prior Specification, and additional sets of rods x, y are provided to give an even action on the rings d which they intercept. In the example illustrated, three groups cf rings are used, the rods x pass through the first two groups, and the rods y through the first group, and each set of rods project sufficiently to engage the ring plate k in turn, so that, when the clutch shifter is separated to release the clutch, the plate k first acts through the rods i<2> to push back the platej to release its grip on the whole of the rings, then acts upon the rods x to push off the rear group of rings, and finally acts upon the rods y to thrust out the central group. The plate k is operated by a clutch shifter consisting of two annular rings B, B' on a sleeve C, and having inclines on their opposed faces, so that, when one ring is fixed and bears against an abutment on the sleeve C and the other ring is rotated by a treadle, the sleeve r carrying the part s acting upon the ring k is moved longitudinally. The rings B, B' are preferably secured to parts D, D<1>, which form a casing on the sleeve C and are provided with overlapping flanges to exclude dust &c., and with flanges 2 forming recesses in which are placed rings 3 provided with balls 4 or rollers bearing against steel rings 5, the parts being held in position by means of a nut 6. An arm projecting from the part D is connected to a fixed point on the motor car, and a similar arm on the part D<1> is connected to a treadle or hand-lever, by operating which the clutch parts are disengaged.

Abstract: 6451. Tillotson, G. March 20. Seats and seat-backs.-In seats with reversible backs for the tops of tramcars and other exposed situations, the weight of the back and operating- parts is utilized to return the back to the central position and turn up the halves of the seat into a recess in the back. The side bars of the back are connected by a cross-bar 3, projecting through or into slots in the end frames. A flanged antifriction roller 10 on each side bar is adapted to run up a double incline 7, and so raise the back when it is moved to either side. Rods 14 connect the crossbar to arms 15 on the halves 5 of the seat, so that, when the back is raised, the seat is opened out as shown in Fig. 5. Stops 16 limit the movement of the arms. The automatic closing action may be assisted by a weight 25 on the cross-bar. This action may be prevented by moving a sliding piece 30, a slot 31 in which normally coincides with the slot in the end frame, into the position shown in Fig. 6, so as to prevent the cross-bar 3 from falling. The Provisional Specification states that an adjustable leg or the like may be provided on one of the rods 14 and adapted to rest upon the ground or otherwise, to prevent the seat from closing.
