BRAKE-BEAM STRUCTURE.
Application filed May 4,
My invention. relates to railway rolling stock and consists in an improved brake beam strut and third or fourth point support chair. It is customary to use a rotatable strut in a truss brake beam so that the-angle of inclination of the brake lever may be changed without using a new strut or a new brake beam. It is also customary to mount a third point support chair on the strut. It is clear that the relation between the chair and the strut must be changed if the strut is re.- versed since the position. of thechair relative to its support should not be changed.
The main object of my invention is to provide a strut and chair structure which will permit the reversal of the strut without changing or removing the chair from the strut. In theaccompanying drawings which illustrate my invention Figure 1 is a transverse section through a brake beam illustratingin elevation my improved strut and chair and indicating a third point support for the chair.
Figure 2 is a view of the end of the strut and of the side of the chair.
Figures 3-and 1 correspond to Figures 1 and 2 but illustrate a modified form of my Figure 5 is a section on line 5-5 of Figure 3. e
Figures 6 and 7 are similar to Figures 1 and 2 but illustrate. another modification of my invention.
Figures 8 and 9 similarly illustrate another modification of my invent-ion.
In the structure illustrated in Figures 1 and 2, the strut is shown as engaging the compression member 2 and the tension memher 3 of a brake beam. The right hand end of the strut forms a bracket 4 of a well-known type which permits the strut to be reversed so as'to accommodate a brake lever inclined in the opposite direction to the inclination provided by the strut in the position illustrated. On the outer end of bracket 4 is a journal 5 projecting axially of the strut and mounting a chair 6 which rides on a track member 7 such as is ordinarily provided under brake beams. I
Preferably the journal bearing in chair 6 will be convexed as indicated at 8 to permit the chair to tilt lengthwise of the strut as Well as transversely of the strut so as to accommodate any inclination which may be provided in a track 7. Washer 'w and cotter 0 hold 1927. Serial No. 188,682.
extension 9 which mounts, a sleeve 10 which is provided with parallel ears 11 between which the chair 12 is carried in the'manner usually provided by the end of the strut proper. Sleeve 10 is retained on the strut ex:
tension by a fcotter 13, the opening inflthe sleeve being elongated circumferentially of the sleeve to permit the sleeve to rotate'rela tive to the strut, when the latter is reversed, sov that the chair may remain in the vertical position in which it will properly engage its track 1-1. F
In the modification illustrated in Figures 6 and 7, the strut extension forms spaced ears 15 and 16 disposed at an angle to the vertical corresponding to the inclinationof the. brake lever. The chair 17 has an upwardly extending hub 18 similarly inclined from the vertical. 7hen the strut is reversed the chair is removed from the strut and is reversed so that its ear or hub 18 extends diagonally upward from the right to the left and the relation between its bearing surface and track 19 is unchanged. V In the construction shown in Figures 8 and 9, the extension 20'on the strut is rectangular in cross section and the chair 21 is provided with two legs 22 and 23, either one of which is adapted to engage the track member 24.
In each form of my invention,the strut may be formed of one piece and in all of the forms except that shown in Figures 6 and 7 reversal of the strut does not require disassembly of the chair as the latter will automatically maintain its proper position. In the form 3 and I contemplate the exclusive use of such variations as fall within the scope ofmy claims.
I claim:
1. In a brake beam, a third or fourth point support chair angularly adjustable on the beam in a vertical plane extending lengthwise of the beam.
2. In a brake beam, a reversible strut and a third point support chair mounted-on said strut independently of'the beam and angularly adjustable about the axis thereof.
3. In a brake beam, a compression member, a tension member, a reversible strut be tween said members with a rigid portion extending beyond one of them, and a third point support chair mounted on said portion and angularly adjustable about the axis thereof.
4. In a brake beam, a one piece reversible strut, and a third point support chair on said strut and adjustable angularly of the strut axis;
' In a brake beam, a'one-piece reversible strut, and a third point support chair mounted onjsaidstrut to pivot about the strut axis.
6. In a brake beam, a reversible one piece strut, and. a third pointsupport chair mounted on said strut and adapted to automatically position itself to engage a support arm irrespective of tie inclination of said strut about its axis or of the longitudinal inclinat-ion of the beam.
T. Ina brake beam, a reversible strut, and a third point support chair pivotally mount ed on said strut to freely rotate in a plane extending transversely of the strut axis, said chair having its center of gravity below the axis of its pivot. V
8. In a brake beam, a compression menr her, a tension member, a reversible strut be tween said members and extending beyond one of them, and a third point support chair pivotally mounted on the projecting portion of said chair to permit reversal of said strut \v.itliouta.tfecting engagement of said chair with its support.
9, In a brake beam, a compression member, a tension member, a reversible strut between said members terminating in an axial journal projecting beyond one of said members, and a third point support chair having a bearing for said journal which bearing is COHVGX lengthwise of the journal to permit 3 tilting of said chaironsaid journal axially thereof.
1.0. In a brake beam, athird or fourth point support chair mounted on the beam to swing freely in a plane extending lengthwise of the beam.
11; In. a bralrebeam, a third or fourth point support chair mounted on the beam to swing freely inany direction relativeto t 12. Ina brake beam, a strut, and a third point support ohairmounted on said strut so as to swing in any direction relative to the strut. V
13'. a third or fourth point support chair for brake beams, a base for sliding in one direction on a support, elements for engagin i a chair mounting so as to permit the chair to pivot transversely of said direction, and depending flanges on the chair for enthe sides of a track member to prevent accidental pivoting of said chair transverseiyof said direction.
14. In a third or fourth point support chair for a brake beam, a base adapted to facilitate sliding of the chair on a support in a direction extending transversely of the length of the beam, and elements for engaging a chair mounting so as to permit the chair to pivot in a vertical plane extending length- Je'of the beam. 1
In a third or fourth point support chair for a brake beam, a base adapted to facilitate 'ng of the chair on a support in a direction nding transversely of the length of the bezun, elements forengaging a chair mounting so as to, permit the chair to pivot in a vertical plane extending lengthwise of the beam and elements to prevent accidental pivoting of said chair on its mounting;
