AIR-BRAKE-CYLINDER ATTACHMENT TO RAILROAD-CARSOR THIE LIKE.

Specification of Letters Patent.

Patented April 13, 1909.

i Application filed September 14, 1908. Serial No. 452,902.

To all whom 'it may concern:v

Be it known that I, HARRY M. PFLAGER, a citizen of the United States, residing at St. Louis, in the State oflrlissouri, have invented a new and useful Improvement in Air-Brake- Cylinder Attachments to Railroad-Cars or the Like, of which the following is a speciication. v

My invention relates to the block or suspension bracket for the attachment of the air-brake cylinder to the underside of a railroad car or analogous vehicle, this attachment ordinarily consisting' of a wood block or built up frame of wrought steel plates, which is heavy and cumbersome and occu ies considerable space, and my invention as for its object to provide a strong, light, rigid, and compact integral structure for the purpose. g Y

It consists in features of novelty as hereinafter described and claimed, reference being had t0 the accompanying drawing forming part of this specification, whereon,

Figure 1, is a top plan view of my im roved air-brake cylinder attachment ap lie to the underside of the longitudinal si 1s (broken away) of a railroad' car; Fig. 2, a vertical transverse section through the sills on line Y l 2, 2, in Fig. 1, showing the'air-brake cylinder attachment in end elevation, and Fig. 3', a perspective view of the attachment detached.

Like letters and numerals of reference denote like parts in all the iigures'j a represents my im rovedrair-brake cylinder attachment whic ably, of cast steel integralfthroughout and com rises in the presentcase preferably, two para lel spaced apart L-shaped bars b having their, lower legs 1 in the .same horizontal plane and theirl upright -legs 2'inward and posite to each other, the horizontal leg 1 v.Leach bar b at a suitable distance from each *end thereof being'curved u wardto a level ',-thence to the portion 1',

:with the edge of the upright eg 2.and formed said Vend with a straight flat the upright leg 2 terminating at the said curvatures of the'horizontal leg 1.

The bars b are united together at a suitable .tolp of the upright legs 4 of. the bars is composed pre'ferdistance vfrom their respective ends by preferably, two parallel s aced apart L-shaped bars c which are at -rig t angles and similarly arranged to the bars b, except that the flat end portions v1l of the latter are eliminated ,and the upwardly curved portions of their lower horizontal legs 3 terminated at and uniting with the upright legs' 2 of the bars b- I at the top which are flush thereat with the c the light, and conipact metal is distributed w ole forming a strong, frame through which the to the best advantage for obtaining the necessary rigidity within the limit of depth or thickness allowed to the frame thereat for maintaining the normal standard level of the air-brake cylinder d which in assembling the parts is` arranged between and fixed tothe underside of the lower horizontal le s 3 of the bars c longitudinally therewith, extending transversely to the car, referably between and beneath the longitu inal sills e to which the flat end portions 1 of the bars b are fixed by bolts 6, all as indicated by dotted-lines. Or the bars b may be otherwise adapted at their end portions forJattachment of the frame to any other suitable part of the car underframe according to the contour and material of the latter.-

A great advantage of my invention is, that by substitutingaa -cast metal integral structure of special design as to strains, for the ordinary wood block'or built up framework of iron with its fastenings, the stability of the air-brake cylinder is positively insured withl less weight of material and liability to work loose under varying conditions of load.

What-l claim as my invention and' desire to secure by Letters Patent is i* A cast metal fair-brake cylinder attachment to a railroad car, having all its parts integral and comprising two opposite parallel spaced a art L-shaped' bars having their horizonta legs respectively, neer each end, and thence to the said end formed horizontally flush with the edge .of the upright .leg of the bar, and adapted thereat to be fixed to the ,underframe of the car-body, and, two opposite parallel spaced y'bolts 5, the bars b.-

curved upward apart L-shaped'bars having their upright ment thereto of the said cylnderfsubstan-l legs at right angles t0, and uniting With the tially as described.

correspondin legs of the irst named bars n and having teir horizontal legs curved up- HARRY M' PFLAGER" Ward'near each endto vtheir Junction With i Witnesses: l
