BRAKE MECHANISM FOR INCLINED RAILWAYS.

Specification of Letters atent.

Patented Oct. 29, 1907.

Application filed May 15. 1907. Serial No. 373,728.

To all 'whom it may concern: Be it known that I, STEPHEN E. JACKMAN, a citizen o the United States, and a resident of the city of New x York, Coney Island, borough oi Brooklyn, in the county of Kings and State oi New York, have invented a new l and Improved Brake Mechanism i, ways, oi' which the following is a description. i The invention relates to brake mechanisms for inclined railways, such as shown and described in Letters Patent oi the United States, No. 749,691, granted to me January 12, 1904.

The object or' the present invention is to provide a new and improved brake mechanism for inclined railways, arranged in the track and under the control oi an operator stationed near the track, to check the l speed or' the car wholly independent of the occupants of the car, and to bring the car to a standstill at the home station.

The invention consists oi novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part oi this specification, in which similar characters or' reference indicate corresponding parts in all the views.

Figure l is a plan view of the improvement, Fig. 2 is a longitudinal sectional elevation oi' the same on the line 2-2 of Fig. 1; Fig. 3 is a transverse section oi the same on the line 3-3 of Fig. l; Fig. 4 is a similar view of the same on the line 4-4 or' Fig. 1, and Fig. 5 is a perspective view of a pair of the actuating cams for the brake shoe.

The inclined railway on which the improvement is applied may be or' any approved construction, preferably, however, one such as is used in exhibition grounds, pleasure resorts and the like, and one having a continuous track A, over which travel the cars B usually drawn up the up-track by suitable machinery, with a view to permit the car to run by its own gravity down the down-track and home stretch back to a station leading to the foot or' the up-track. This iorm of continuous track is well known, so that further description of the same is not deemed necessary.'

Now in order to brake the car and to check its speed and gradually bring it to a standstill at the station, the ollowing brake mechanism is provided, which brake mechanism is controlled wholly independently of the occupants oi the car by an attendant standing adjacent to the track at or near the homelstation. A brake beam C is secured to the under side oi the body of the car B, preferably at the middle thereof (see Fig. 4), and when the car nears the end of the home stretch the said brake beam G passes between the brake shoes D, D ranging in the direction oi the length or' the track and 1 for inclined Raill'ull, clear, and exact provided at their inner or opposite sides with rubbing irons D2, D3 inclined outwardly at their ends for the convenient entrance oi the brake beam C when the car reaches the brake mechanism. On the track A and arranged parallel to the brake shoes D and D are secured longitudinally extending beams E and E between which and the corresponding brake shoes are arranged cam mechanisms F and F for moving the brake shoes D, D inwardly in braking engagement with the beam C to check the speed of the car B and to linally bring the same to a standstill.

The several brake mechanisms F and F are alike in construction, and each consists of a cam F2 fixed on a transversely extending rod G secured to the corresponding brake shoe D or D and extending through the corresponding fixed beam E or E.

vThe fixed cam F2 has its cani surface in contact with the cam surface of a brake ,lever F3 mounted to turn on the rod G and abutting against the fixed beam E or E so that when a turning motion is given to the cam lever F3, then the cam F2 and the corresponding brake shoe D or D is moved inwardly in braking engagement with the beam C. Normally the brake shoes D and D are held in an outermost inactive position by the action oi springs H coiled on the rod G, and resting with their inner ends on the beams E and E and with their outer ends abutting against the outer heads of the rods G, as will be readily understood by reierence to Fig. 4.

The brake mechanisms F and F are arranged in pairs in transverse alinement with each other, as plainly indicated in Fig. 1, and the cam levers F3 of a pair oi cam mechanisms have their depending arms F4 connected with each other by a transverse bar I trunnioned in the arms F4, and the several bars I are pivotally connected with a longitudinally extending reach rod J pivotally 4connected by a link ll with a transversely extending lever K iulcrumed at one end to one side oi the track A and connected at its free end at the other side oi the track by a link K vwith an upwardly extending lever L under the control oi the operator standing at one side o the track at or near the home station. Now when the operator pulls thev lever L in the direction o the arrow d (see Fig. 1), then a swinging motion is given to the lever K which by the reach rod .l and bars I impart a swinging motion simultaneously to all the cam levers F3, to push the cams F2 and the brake shoes D and D inwardly in engagement with the brake beam C on the car now traveling over the track at the point where the brake mechanism is located. Thus when a car approaches the brake mechanism and the operator actuates the lever L in the manner described, then the brake shoes D and D engage the brake beam C to check the speed oi the car and to bring the same gradually to a standstill, without shock or jar to the car and its occupants.

It is understood that when the brake shoes D and D are moved inwardly into active position by the action of the cam mechanisms, then the springs H are compressed, and when the operator returns the lever L to its normal vertical position then the cam levers F3 are returned, and the springs H draw the brake shoes D and D/ back to their normal outermost inactive position, thereby releasing the brake beam C and consequently the car B. Y

It is understood that by the operator pressing the hand lever L with more or less iorce, any desired braking effect can be had on the car beam C and consequently on the car B to check the speed thereof. When the car has been brought to a standstill, the occupants thereof disembark and pass by way of the platformto the exit of the station, after Which the car is usually pushed by an attendant to the embarkation side oi the station, to be filled With passengers and to be iinally passed to the ioot of the up-track, at which the usual mechanism takes hold of the car and pulls the same up the 11p-track. Itis understood that as long as the' hand leverfL is in the applied position, the car is practically held locked by the brake mechanism, and when it is desired to release the car it is only necessary for the operator to swing the hand lever L back to its normal vertical position.

By theA arrangement described, it is not necessary to send an attendant with thecar over the track, as the speed of the car when reaching the end of the home stretch is perfectly under the control oi the operator manipulating the hand lever L, on seeing a car approaching the brake mechanism, as the home stretch of the track A is usually straight.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
