BRAKE FOR RAILWAY-CARS.
Continuation of application Serial No.
To all whom it may concern:
Be it known that I, ELISIARIO CASTANHO, a citizen of Brazil, and a resident of the city of Sao Paulo, State of, Sao Paulo, Brazil, have invented a new and Improved Brake for Railway-Cars, of which the following is a full, clear, and exact description.
The present application is a continuation of the application Serial No. 798,001, filed by me October 29, 1913, on which United States Patent No. 1,112,979 was issued October 6, 1914.
The present invention relates to novel brakes, which will be hereinafter particularly explained. j I
Reference is to behad to the accompanying drawings forming a part of this specifi-,
cation, in which similar characters of reference indicate corresponding parts in all the views. 3 I f Figure 1 is a broken plan view with parts in section, illustrating] one, embodiment of my improved brakes and the means for applying the same; Fig. 2 is a face view of one of the brakes, with fragments of a track rail; Fig. 3 is a detail end View of the brake shown in Fig. 2, the track rail being shown in section; Fig. 4 is a face view showing a.
modified form of brake; Fig. 5 is a view similar to Fig. 3, but illustrating the modified brake shown in Fig. 4; and Fig. 6 is a view similar to Figs. 3 and 5, but illustrating a further modification.
My improved brake is more particularly adapted for use in connection with track rails more or less elevated.
Referring more particularly to Figs. 1 to 3, I have indicated a track rail A, having upper and lower heads, said rail being supported by brackets B secured to posts C in connection with which braces D may be employed. The brake includes an upper brake element and lower brake elements which may be eitherrollers or shoes. In the form shown in Figs. 1 to 3, rollers are employed, the brakes being designated generally by the numeral 40. The brakes are supported on any suitable frame members of the car; I have indicated longitudinal frame-members 35 and cross bars 35. These frame-members support bearing members 36 in which vertical shafts 37 are mounted to turn. Each brake comprises a brake block 42, in which is j ournaled an upper brake roller 43, and a lower brake block 44 in which is jour- Specification of Letters Patent. Patented July 2%}, 1915.,

naled a pair of lower brake rollers 45, which are 111 staggered relation to the upper roller. The upper roller 43 is adapted to bear against the top of the track rail A, while the lower rollers-bear against the under side of the trackrail. The shafts 37 have right and left'threads 46, 47, engaging corresponding threads in the respective brake blocks 42, 44, so that the turning of the shaft 37 in the bearings 36, will serve to move the brake rollers against the rail A, or away from the rail to apply or release the brakes. Any suitable means may be employed for actuating the shafts 37. I have shown said shafts provided with sprocket wheels 38, around which an endless chain runs, said chain presenting runs transversely of the car to and from the sprocket wheels 33 and running also over idler sprockets 39 and over sprockets 39. on a vertical shaft 39 which may be provided with a hand wheel 39 indicated in dotted lines (Fig. 1). It is to be understood that there is a sprocket chain and the described arrangement of sprocket wheels for each end of the car, as will be clear from Fig. 1, the respective hand wheels 39 being adjacent to each other, to be turned by the motorman or other attendant.
In the form shown in Figs. 4 and 5, shoe brakes are employed, designated generally by the numeral 41, there being an upper brake block 42" having a shoe 43 and a lower brake block 44 having shoes 45 in staggered relation to the upper shoe 43, the same arrangement of shaft 37 with the described right and left threads 46, 47, being employed. Thus the turning of the shaft 37 will move the shoes into engagement with the rail A, or away from said rail.
In Fig. 6, a difi'erent arrangement of rails is employed, and the brake elements illustrated as rollers are modified accordingly. A lateral rail A and vertical rail A are suitably supported on a post C having a brace D. An upper car wheel E is indi-' cated as running on the vertical rail A and a lower wheel F is indicated as running against the under side of the head of the laterally disposed rail A. It is to be understood that the particular arrangement of tracks and car wheels, isnot claimed in the present application. /Vith the arrange,- ment of rails shown in Fig. 6, a horizontal shaft 37 c is employed, having right and left threads 46, 47 engaging corresponding threads in brake blocks 42", 44*, in'which are journaled rollers 43", 45 disposed on vertical axes at opposite sides of the vertical track rail A With the form shown in Fig. 6, it will be seen that the turning of the shaft 37 will cause the brake rollers to bear against the vertical rail, or to be released from the rail.
In all the forms, the brake blocks in addition to a travelingmovement toward and from each other on'the right and left threads of the actuating shaft, have guided sliding movement on guide elements. In the forms shown in Figs. 1 to 5 guide spindles l 8 are .1. A car, having at eachside thereof brake elements, the brake elements at each side being vertically spaced to accommodate a track rail therebetween, vertical shafts having right and left threaded engagement with the brake elements, to move the same toward and from each other, sprocket wheels on said shafts, anendless chain passing around said'sprocket wheels and having runs transversely of the car to and from the ment for the opposite side, the respective elements being in staggered relation, blocks carrying said brake elements, a shaft having right and left threads engaging corresponding threads in the said blocks, means for turning said shaft and a guide spindle disposed between the blocks and slidably guiding the blocks in their movements toward and from'each other, in response to the turning of the said shaft. I 8,. In a railway brake, brake elements spaced to accommodate a track rail therebetween, blocks carrying said brake elements, a shaft having right and left threads engaging corresponding threads in the said blocks,means for turning said shaft and a guide spindle disposed betweencthe blocks and slidably guiding the blocks in their movements toward and from each other, in response to the turning of the said shaft.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
