WILLIAM PANTER, JOHN CHARLES TAITE, AND THOMAS WILLIAM CARLTON, OF LONDON, ENGLAND.

SPECIFICATION forming part of Letters Patent N 0. 437,449, dated September. 30, 1890. Application filed February 10, 1890. Serial No. 340,807. (No model.) Patented in England Maroh 8, 1889, No. 4,100; iii-Ger- 7 many May 5, 1889, No. 52,836; in France May 27, 1889, No. 198,530, and in Belgium May 27,

To all whom it may concern.-

Be it known that we, WILLIAM PANTER, JOHN CHARLES TAITE, and THOMAS WILLIAM CARLTON, subjects of the Queen of Great Britain and Ireland, all residing at London,

England, have invented new and useful Improvements in Brake Apparatus for Vehicles, such as railway-wagons, (for which we have receiveda patentin France, No. 198,530, dated May 27, 1889; in Belgium, No. 86,402, dated May 27, 1889; in Great Britain, No. 4,100, dated March 8, 1889, and in Germany, No. l 52,336, dated May 5, 1889,) of which the following is a specification. r5 This'invention has reference to brake apparatus for vehicles-such as railway-wagons-that may be readily operated by hand from either side of the vehicle for the purpose of applying or releasing the brake block or blocks and for fixing the same in the on or oft positions, as required. For this purpose the brake block or blocks is or are connected through suitable mechanism with a hand-lever that extends transversely, or approximately so, of the vehicle, and has its ends conveniently arranged for .being actuated from either side of the vehicle. The hand-lever is provided with a tooth or projection that can be engaged with or disengaged from one or other of a series of notches formed in a suitable plate or frame forming a holding device attached to the vehicle. The lever on one side is, or may be, held in position by a spring, which may in some cases also form a fulcrum for the lever when releasing the same from the holding device from the side of the vehicle opposite to that at which this device is secured.

In order that the brake-shoe may be ap- 4o plied without shock andthe pressure thereof on a wheel be adjusted as, required, a spring may be arranged between the lever that is connected to the brake-block and the rod through which such lever is actuated.

Means are or maybe provided whereby the effective length of the connecting-rod between the hand-lever and the brake-block lever can be adjusted from time to time to compensate for wear of the brake-shoe. 50 As will be obvious, a hand-lever, with holding device arranged according to this invention, may be used with brake apparatus of various constructions.

In the accompanying drawings, Figure 1 is a side elevation of a part of a railway-wagon fitted with brake apparatus according to this invention. Fig. 2 is a transverse sectionof the vehicle with the brake apparatus in elevation, and Fig. 3 is a plan. Fig. 4 is a detail view to a larger scale. Figs. 5, 6, and 7 are respectively side, end, and plan views of part of a vehicle with brake apparatus according to this invention, showing a different arrangement of the hand-lever. Fig. 8 is" a detailview to a larger scale. Figs. 9, 10, and 11 are respectivelya side elevation, transverse section, and plan illustrating a modified arrangement of the brake apparatus. Fig. 12 is a plan view illustrating another modified arrangement of brake apparatus ac- 7o cording to this invention.

1 is a brake-block with shoe hung by a link 2 from the beam 3 of the vehicle. On the back of the block is a loop or stirrup 4, through which there passes a lever 5, which 7 5 is pivoted to the said loop or stirrup. The outer end of this lever is connected by a rod or link 6 to the horn-plate 7. The inner end is coupled or connected to a rod 8, which is pivoted at its other end to a hand-lever 8o 9. This hand-lever is pivoted at 10 to the head-stock, and according to this invention stretches across the wagon, so that it can be operated from either side thereof. It moves in a stirrup or guide 11 at one end, and in this guide there are notches 12. A tooth 13 on the lever 9 can be made from either side of the vehicle to take into one or other of these notches, in order to keep the brake: block and attached parts in the on or 01f position after the lever has been operated.

The pressure exerted on the lever 3 by the rod 8 in applying the brake may advantageously be transmitted through a spring 14. This enables the brake to be applied with 5 any desired degree of force and lessens shock when applying the brake and during shunting operations. The spring is interposed between the lever 5 and a nut and washer on the end of the rod 8. 15 is a coupling by I00 which the length of the rod can be adjusted to compensate for wear of the brake-shoe.

To release the brake from the side of the vehicle, (shown in Fig. 1,) the toothed end of the lever 9 is lifted to bring the tooth 13 out of the notch 12 in which it was held, and the lever then moves or is -moved forward. It can then be secured in the off position by engaging the tooth in the end notch 12. To relowered from either side of the vehicle.

lease the brake from the opposite side of the vehicle, the end of the lever at the side is depressed to lift the tooth from the notch, and thenit is raised to' again engage the tooth. The fulcrum-pin 10 of the hand'lever has sufficient play in its bearings to enable the toothed end of the lever to be thus raised, and A spring 16, secured to the vehicle, serves to hold up the end of the lever on the side remote from the stirrup or guide 11.

In Figs. 5, 6, 7, and 8 the hand-lever 9 is .pivoted to the end of the vehicle'so as to work in a vertical plane, and extends to each. side of the vehicle, so that it can be conveniently operated from either side thereof. The

,lever is connected to the operating-rod 8 by tion of gravlty.

a rod 8 and bell-crank lever 8*. In this arrangement of brake apparatus there is a suspended brake-block 1 for each of the two wheels at one side of the vehicle. The two blocks are connected by links 4*" to a lever 5 fixed upon a rock-shaft 5 upon which the operating-lever 5 is also fixed. This lever 5 is operated through a rod 8, as in Figs. 1, 2, and 3, from the hand-lever 9, through the rod 8 and bell-crank lever 8*, hereinbefore mentioned.

In Figs. 9, 10, and 11 the hand-lever 9 is connected to the rod 8, which, in this case, is made much shorter than in the other arrangements, hereinbefore described, by two rods 8 8. These rods are slotted at their ends adjacent to the hand-lever, and are con nected thereto by pins 8 that are able to slide in the slots. With this arrangement, as will be obvious, in whichever direction the hand-lever 9 is moved from the normal position in which it is shown the brake-blocks 1 will be applied to the wheel. When the lever is returned to its normal position, the brake-blocks will be released, but will not be positively taken off the wheel, owing to the pins 8 moving in the slots in the adjacent ends of the rods 8'; but the blocks will be free to move away from the wheel by the ac- The hand-lever 9 can, as in the previously-described arrangements, be raised or lowered from either side of the vehicle for the purpose of engaging its projection 13 with or disengaging this projection from one or other of the notches 12 in the stirrup or guide 11. The spring 16 in this arrangemen't is fixed to the hand-lever and bears against the under side of the notched stirrup or guide 11, so as to normally keep the projection 13 within one of the notches 12.

Fig. 12 illustrates an arrangement of brake apparatus similar to that shown in Figs. 9, 10, and 11, but in which the ends of the two rods 8, adjacent to the hand-lever 9, are not slotted, but are jointed to the lever by the pins 8 so that when the lever is moved in either direction from its normal position both rods will be operated. The other ends of the rods 8 are jointed to' one end of a pair of links 8, the other end of which is jointed to the rod 8. With this arrangement the brakeshoes will be put on the wheel when the hand lever 9 is moved in either direction from its normal position, and will be positively taken off the wheel by the lever when the same is returned to its normal position. By the construction shown the point of connection A of the rods 8 with the pair of links 8 will, when the hand-lever is operated, move in an arc of a circle having its center coinciding with the center of motion of the lever.
