' JOSEPH FQHENNER, OF HAINES, OREGON.

CAR-BRAKE.

To all whom it may concern:

Be it known that I, JOSEPH F. HENNER, a citizen of the United States, residing at Haines, in the county of Baker and State of Oregon, have invented certain new and useful Improvements in Oar-Brakes, of which the following is a specification.

The invention comprises new and novel brake mechanism especially designed for application to any of the various types of railway-cars now in use.

The essential feature of the invention resides in the provision of braking mechanism composed of a structure and arrangement of parts adapted to produce a maximum braking action with reference to the wheels of the rolling-stock in the practical operation thereof.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for "effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details Without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which Figure 1 is a vertical longitudinal sectional view showing the invention applied to the body-of a car. Fig. 2 is a bottom plan view bringing out more clearly the arrangement of the parts. Fig. 8 is a perspective view showing the brake mechanism alone. Fig. 4 is a transverse sectional view on the line X X of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates the body of a car, and it will be noted that the same may be of any suitable type at present in use, this being immaterial within the contemplation of the invention. The body 1 is mounted upon trucks 2, and the latter may be of any conventional construction, consisting, preferably, of transverse frames 3, having the longitudinal trussframes 4 at the ends of the frame 3, the frames 4 having the axles 5 mounted in the ends thereof. The trucks 2 are double trucks,- and the frame 3 of each truck carries Specification of Letters Patent.

a bolster upon which the body 1 of the car is directly supported.

It is designed to use the brake mechanism embodying the invention in connection with the brake devices which are ordinarily used upon cars and which consist commonly of the brake-beams 6, supported at opposite ends of each truck 2, the outermost of each of the brake-beams 6 being operably connected by suitable rods 7 with a horizontal bar 8, arranged upon the under side of the body 1. The rods 7 connect directly with brake-levers 9, pivoted between theends thereof to the outer brake-beams 6, the lower ends of the brake-levers 9 being connected by rods 10 to the inner beam 6, or those which are disposed between the trucks 2. Suitable operating-rods 11 connect with the outer ends of the bar 8, and these rods 1 1 maybe operated by the motorman or operator of the car in any suitable mannerby hand-power or otherwise, as found best. The rods 11 are two in number and extend toward opposite ends of the car-body, so that the bar 8 may be actuated from either end of the car. lVhen one of the rods 11 is pulled upon, the brakebeams 6 at opposite ends of each of the trucks are actuated in the customary manner.

The brake mechanism which constitutes this invention comprises the brake-beams 12, which are arranged transversely of the trucks 2, between the front and rear wheels of each of said trucks. The brake-beams 12 are of any approved construction and are provided I with brake-shoes, as are the brake-beams 6. Toggle-links 13 connect each of the brakebeams 12, and these links 13 are connected together by means of a pintle-bar 1 1,'whichis nearly as long as the brake-beams 12, above described. The end portions of the pintlebar 14 adjacent each truck are connected by flexible connections 15 with supportingframes 16, carried by the under side of the car-body 1. The supportingframes 16 are of somewhat U form and consist of side bars 16 and an end bar 16 The frames 16 have the side bars 16 thereof connected near the extremities opposite the bar 16 by rods 17. The frames 16 are pivoted to the car-body, and two of these frames 16 are arranged adjacent each truck, suitable bearing-plates 18 extending from the under side of the car: body and receiving the end bars 16 of each frame 16 toafford p'ivotal connection there- ICC of, as above premised. .Extremities of the side bars 16 are arranged approximately above the transverse frame 3 of each truck 2, and these extremities have connections '15 attached thereto, so that when the frames 16 are actuated or raised the pintle-bars 14 will be moved upwardly, and the toggle connections 13 will cause the brake-shoes of the beams 12 to positively engage the adjacent wheels of the afford great truck. The toggle members 13 leverage in causing the brake-;

beams with which they are connected to be 1 engaged with the wheels of the truck. The

brake-shoes of the various beams 12 and 6 l are indicated at 19, and the shoes 19 of the I beams 12 are supported by links 20, connectmg the upper portions of said shoes with the ust above described. Mounted upon one side of each of the transverse frames 3 of the 1 trucks 2 are located sets of toggle-levers 22,

a set of these levers being provided for each truck. The levers 22 may be described as of The approximately U form, being pivoted to-;'

gether at one end, as shown at 23.

One of l the levers 22 of each set of toggle-levers is pivotally connected with the cent, as shown at 24, the other of said levers truck 2 adjahaving pivotal connection (indicated at 25) with a cross-rod 17 of Only two of the frames 16 are provided with the cross-rods 17, the latter being utilized, primarily, to afford the necessary connection between the frames 16 and the toggle-levers 22. The toggle-levers 22 are set upon the outer side of one truck 2, the other set upon the inner side of the other truck 2. A lever 27 is connected at one end an adjacent frame 16.

arranged one I to the inner side of the toggle-levers 22, the

opposite end of said lever being connected by a cable-rod or like connection 28 to a lever 29, I

the latter being pivotally connected at a point between its ends with the outer set of toggle-levers 22. The lever 27 be actuated by foot-power or the like, and a fplot-lever 30 may t e is adapted to be disposed at one end of car-body 1, convenient to the motor-man, I

said foot-lever being connected by a connection 31 with the lever 27 at a point between the ends of the latter.

The lever 29 has connection at a point between its ends with the toggle-levers 22adjacent, the end of the lever I 29 opposite that connected with the part 28 being pivotally connected with the adjacent transverse frame 3, as shownat 32.

The above sets forth clearly the exact structure preferred in the construction of the inplied to the wheels they are vention, and the operation of the brake mechanism is as follows: shoes 19, carried by the brake-beams 6, may be applied to the wheels of the car by actuation of the brake-rods 11 in the customary manner, and these brake-beams 6 are operated simultaneously with the brake-beams 12. It will be noted that when the operating mechanism by which the brake-shoes 19 are applied is actuated the tendency of the brakeshoes when the same engage with the wheels is to turn with the wheels because of the engaging action of said shoes. A certain amount of movement of said brake-shoes 19 is admitted of by the arrangement thereof and the construction of the mountings therefor, and as soon as said brake-shoes 19 are apmoved upwardly a short distance by the braking engagement between the wheels and the same, and such upward movement forces the lines or members 21 upwardly, and as these members 21 form rigid connections between the several frames'16 and the shoes 19 it will be seen that the frames 16 will have pivotal movement imparted thereto and the end portions of the frames which are connected with the brake-beams '12 will be raised and the brakeshoes carried by the brake-beams 12 will be thrown into braking cooperation with the wheels by the actuation of the toggle connections 13. The brake-shoes 19 when applied thus constitute the means for actuating the brake mechanism, which includes the frames 16 and the brake-beams 12, connected with said frames 16. In order to afford, however, the greatest amount of braking action, the brakeman will operate the foot-lever 30, (or this may be a hand-lever,) and by so doing the lever 27 will be pulled upon, causing the adjacent toggle-levers 22 to move toward analined position and raise the frame 16, to which said toggle-levers are connected. Simultaneously with the raising of the frame 16 aforesaid the connection or cable 28 opcrates the lever 29, so that the toggle-levers of the other truck are also actuated to force the adjacent frame 16 upwardly. The upward movement of the frame 16, as above described, will actuate the brake-beams 12, and the tension upon the toggle-links 13 Will cause the brake-beams 12 to spread and wedge against the adjacent wheels in a manner readily apparent. The upward movement of the frames 16 also raises the brake-beams 6 because of the link connections 21, and if the brake-shoes 19 of these beams are applied the braking action of these shoes will of course be increased.

Two or more sets of the toggle-levers 22 may be provided with the trucks 2, according to the size of the car to which the brake mechanism is applied; but it will be readily understood thatthe greatest amount of braking action is secured by the peculiar arrange- If desired, the brakement of the toggle devices 22 in connection with the toggle-links 13, these parts being essential and of immense advantage in the preferred embodiment of the invention.
