T0 all whom t may concern.-

Beit known that I, PH nonon SUCHLAND, of the city of Berlin, Prussia, Germany, have nvented certain new and useful Improvements in Car-Brakes, (for which apatentwas applied for in Germany on the'25th January, 1886,)0fwhich I declare the following to be a speciiication.

My invention relates to improvements in brakes for railway and other cars or carriages.

In order to effectually brake railway and other cars with rapidity in case of danger, I employ a wedge-brake, either alone or in combination with the customary brake. If my said improved brake is employed alone, it is arranged to operate gradually, or, if desired, with great energy, and almostinstantaneously. If the same is employed in conjunction with the ordinary brake mechanism as dangerbrake only, it is arranged to act instantaneously, and will bring the car or carriage to which it is attached, in the shortest possible space of time, to a standstill. lAs a matter of course, the brake'is arranged to act on the car or carriage irrespective of the direction in which the same is driven.

Figure l is a longitudinal section of the lower part of a tramway-car with my improved brake mechanism. Fig. 2 isaside view of the same with the brake applied. Fig. 3 is a top view and Fig. 4 a cross-section.

rlhe brake is arranged at one end of the car, and in order to avoid having to turn the brake-handle to the right when driving in the one and to the left when driving in the other direction, I employ two spindles, ct and b, which carry the pinions c d, which latter are in gear with the double toothing of the rod or rail e. This said rack or rod e runs along the entire length of the car or carriage, and is carried at each end, and, if necessary, at any suitable intermediary part, in appropriate bearings.

The rod e is provided with the two U-formed -standards or double brackets fg, which -are each slotted at h t', and in which said two slots the pins or bolts k l, affixed to the longitudinal rod ym, are guided, so that the said rod can glide beneath the two standardsfg.

Two brackets, no, are xed to the longitudinal rod m in such manner that the springs p q on the rods or spindles r s, which have their bearings at the one end in the brackets n 0 and at the other end iu the standards or double bracketsfg, will press at the one end, against the bracket a oro and at the otherend against the standard or double bracket j' or g. At about the center of the length of the rod m, I attach two bearings, m u, and at the ends of the same like bearings, tu, in which the cross-rods o w op are arranged, which latter carry at their ends the brake-blocks a: y.

At the forward end of the rod e is a frame or sliding guide, z, iu which the sliding rod a is guided, to the ends of which the two slides b are attached, which glideviu the two U-shaped standards Z', and carry the eight brake-wedges c d, which are located above the wheels e f.

The vertical side ofthe rectangular slides b is provided with curved slots y', in which the pivots so gear that by the longitudinal moveinentof the slides the brake-blocks are pressed against the wheels. Springs t" are arranged beneath the slides and press continuously against the same, so as to hold the said slides constantly in their highest position, when the rods h will lie in the lowest point of the saine, where the two converging inclines of the slides meet.

The operation of my improved brake is as follows, whereby it is supposed that the car is being driven in the direction as represented by the arrows: The crank-handle c, which can be readily applied or removed, is placed on the right-hand spindle b, and in braking is turned to the right, so that the toothing of the rod e, and thus the entire rod, is moved in the A direction ot the arrow and the spring q compressed, whereby the rod e, or its standards or double bracketsfg, will, in consequence ot' the slots in the same and the guide-pins k Z, glide on the longitudinal rod m, which is drawn forward by the spring Q, so that the brake-blocks x are brought in contact with the 4wheels and a gradual braking operation attained. If, however, it is desired to effect a rapid braking, the crank It is rotated farther, so that the brake-blocks c are pressed onto the wheels, and are automatically drawn faster and an almost instantaneous stoppage of the car or carriage obtained. In moving the wedges toward the wheels the connecting-rod a glides in the frame z. Ifthe crank cis now given free movement, the brakewedges c will retire from the wheels and the slide b will be returned to its original position, as shown in Fig. 1, by means of the springs i. If the car or carriage is running in an opposite direction, the crank k is applied to the spindle a, in consequence of which the brakeblocks y and brake-wedges d come into action.

In order to retain the brakes in braking position, the spindles a and b can be provided ith a suit-able ratchet-wheel and pawl, and instead 'of making the crank k removable, a suitably-bent crank can be so applied to each of the spindles a b that the operation ofthe one is'not hindered by the other.

4Having now particularly described and ascertained the nature of my said invention for improvements in car-brakes and the manner in which the same is to be performed, I de- 2. In brakes for railway and other cars or carriages, the combination of the rod e, pinions c d, spindles a. b, and crank k with the longitudinal rod m, brackets fg, and pins or bolts k l, substantially as and for the purpose set forth in the foregoing specification, and represented on the accompanying drawings.

3. In brakes for railway and other cars or carriages, the construction of the rod e, pinions c d, spindles a b,crank k', longitudinal rod m, vbrackets f g, and pi nsk l, in combination with the brake-blocks as y, springsp q, rod a', frame z, slide b,wedges c d', the pins or bolts h', and the springs i', substantially as and for the purpose set forth in the foregoing specification, and shown in the accompanying drawings.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
