JOHN P. TEMPLEMAN, OF CHICAGO, ILLINOIS SUPPORT FOR BRAKE-OPERATING MECHANISM .Application filed August 31, 1927. Serial No. 216,550.

This invention relates to railway brakes and more particularly to means for support ing the brake operating mechanism from the cars.

The principal object of the invention is the provision of a new and improved supporting means for the brake operating mechanism that is of universal application and that may be readily and easily assembled in position on a railway car.

Another object of the invention is the provision of a new and improved brake operating unit that is adapted to be assembled as a unitary structure and capable of use on any and all types of cars without changes in the construction of the unit itself.

A further object of the invention is the provision of a new and improved support for railway brake operating mechamsm that 1s 7 2 capable of universal use on cars and the like, that is cheap to manufacture and easily applied to the cars and that is not likely to become broken. 7

Other and further ob ects and advantages of the invention will appear from the following description taken in connection with the accompanying drawings, in wh1ch- Fig. 1 isa transverse vertical section of one I end portion of a railway car, showing the invention in position thereon,the same bemg taken on the l1ne 1-1 ofFig. 2;

Fig. 2 is a view at right angles to that shown,

in Fig. 1, taken on the line 22 of Fig. 1; I

Fig. 3 is a perspective view of the bottom anism support and Fig. 4.- is a perspective view of the bottom side of said plate.

There are many different types and forms.

of street and railway cars and these different types often difier materially in their construction. In applying the brake operating mechanism to these different styles of .cars, it is the common practice to provide a different and distinct form of brake operating mechanism supporting means for the dif 'ferent forms or types of cars. This 1s objectionable because it requires different moulds and tools for manufacturing the dif 5 'ferent types and also necessitates the repair plate or member of the brake operating mechshops of the roads maintaining a s'uflicient/ supply of these different parts to meet all contingencies. I

In order to avoid these objections the present invention seeks to standardize the brake operating mechanism supporting plates or. members. By means of applicants construction the supporting members and brake operating mechanism may be assembled as a unitary device or structure, and by providing means on this device for attaching support-.- ing brackets of different lengths and forms, the device may be readily attached to any car by providing the proper shaped brackets or supports.

Referring now to the drawings in which similar reference characters are employed to designate the same parts throughout the description, the reference numeral 10 designates the end'sill of a railway car and 11 a longitudinal sill thereof. Since the detailed con struction of the car constitutes nopart of the present invention it is not thought necessary to further illustrate or describe the same.v

The brake operating mechanism 12 is supported from the sills 10-and 11 at the end of the car in a manner that will now be described.

The support 13 for this mechanism comprises a lower member 14 and an upper member 15 which are held in spaced relation by any suitable means. As shown the lower member is provided with the flange 16 at each side thereof which is adapted to lap corresponding flanges 17 at each side of the upper member 13. The overlapping portions of the

flanges

16 and 17 are provided with openings for receiving the rivets 18 or the like. The upper member 13 is provided with an opening 19 for receiving the journal or hub 21 of the operating pinion 22; The lower end of so the pinion22 is provided with a journal 23 for engaging a corresponding opening or bearing QL in the lower member 14.

The lower member 14 is provided with an offset portion 25 having a recess or opening ing recess or opening 28 for receiving the upper end of the drum journal. A rivet or bolt 29 extends through the axis of the drum and the upper and lower supporting members 13 and 14, for holding the parts in assembled relation. The drum is provided with a gear 31 which is adapted to mesh with the pinion 22, as is usual in such constructions. The pinion 22 is adapted to be rotated by the brake staff 32, in a manner well known in the art.

stitute no part of the present invention, it is not thought necessary to further illustrate or describe the same. 7

The upper and lower supporting members 13 and 14, with. the gearing in constitute'what, for convenience, will be termed a brake operating unit.

The brake operating unit comprising the .upper, and lower supporting members 13 and 1 1 and the operating mechanism carried thereby may be employed on any type of car,

. it only being necessary to provide suitable brackets or supporting arms for securing the I same to the particular car.

It has been the common practice to supply each different type of car with a dilierent brake operating mechanism support, but with the present invention it is only necessary to. provide different bracket supporting arms. The unitinay be supplied without these brackets, which inay be readily attached at the time the unit is ini stalled.

Any suitable means maybe provided for supporting the brake operating un t. The form of construction shown is by way of example only, since these supporting brackets or arms will diiier widely depending on the type of car on which they are employed.

As shown, a plurality of

arms

20, 30 and 4:0, are employed for this purpose.

and are rigidly secured to the brake operating unit. Any suitable number of arms or brack ets may be employed. They are rigidly secured at their inner ends to the un t and at their outer ends to the adjacent end and center sills, or to anyother convenient portion of porting arms "npos'tion in said recesses.

'The bottom wall oftlie recessesmaybe, and" preferably are, provided with integral studs 39 which may be headed over for holding the attaching brackets in position. These studs In the form of the device shown in Fig. 1,

i only three supporting

arms

20, 30 and 40 are Since the details of the brake operating mechanism or gears consecured .there- These arms are bent or forged to the required shape shown. These arms are bent, forged, or cast, to the proper form and the arms or supporting brackets 80 and 4:0 are rigidly attached at their outer ends to the lower flanges of the longitudinally extending beams or center sills 11, as at 42, and the supporting arm 20 is attached to the end sill 10. *In" the form shown, these supporting arms'a'resuflicient, although a recess is provided for receiving a fourthif itis-i'ou nd to be desirable.

It will thus be seen that the brake operating unit comprisingthe upper and lower sup porting members and the operating mechanis m may be assembled as a unitary structure and is then adapted for universal applica tion. "To attach the unit to any'car it is only necessary to supply brackets or supporting arms of the necessary length and shape. When attached the brake staii is slid into po sition ai1cl ,'tlie'device is completelyin stalled and readyi'or use. While I have' d'is'closed the operating mechanism: as comprising reduction g'earing,'it is understood thatany type of operating mechanism maybe 'em- ,ployed as the particular type o f'mclianism is immaterial so far as the present invention is 4 concerned.

It'is thiight from theftoregding taken in connection with the accompanying "drawings that the construction and'operatioii of inyffdevice will bea-pparent to thoseskill'ed in the art, and that varioiis changes insize, shape, proportion and detailsof construction be made without departing from'the spirit and scope of the appendedclaims.
