J. A. LIGHTBODY. BRAKE RIGGING.

APPLIGATION FILED 00T.l2, 1906.

QLLQ 5 UNITED STATES PATENT OFFICE.

To all whom it may concern.-

Be it known that I, JAMES ALBERT LIGHT- BODY, a citizen of the United States, residing at Waterville, in the'county of Kennebec and State of Maine, have invented new and useful Improvements in Brake Rigging, of which the following is a specification.

My invention pertains to the brake-rigging cars and it contemplates the provision of a brake-rigging designed with a view of assuring safety and of withstanding the rou h usage to which railway-brakes 'are-ordinari y subjected.

The invention Will be fully understood from the following description and claims when the same are read in connection With the accompanying drawings, forming part of this specification, in Which Figure l is av front elevation illustrating the rigging constituting one embodiment of my invention as properly applied. Fig. 2 is a vertical sect-ion taken in the lane indicated by the line 2 2 of Fig. 1 100 n in the direction indicated by the arrow. a plan view of the rigging, and Fig. 4 is an enlarged detail perspective view illustrating a portio n of the brake-beam and my novel safety-loo p attached thereto.

Similar letters designate corresponding parts in all of the views of the drawlngs, re-

erring to which A is a car-axle.

B B are the wheels carried by the axle.

C is a truck-bar having lower and upper flanges a and. b and also having apertured In S 0.

I) 'is a brake-beam, of the form shown in construction or'of any other suitable form compatible With the purpose of my invention, equipped With brake-shoes d. v

E are han ers through which the end portions of the cam D are connected with the ,lugs c of thetruck, and F is my novel bracket for assisting in the suspension of the brake-beam D from the truck. The said bracket F comprises a top bar e, fixedly connected at f to the top flange 1) of the truck and extending at a-right angle thereto, and a brace-bar g, fixedly connected at k to the lower flange (1 of the truck-bar and extendin upward and outward from said flan e .an'

referabl though not necessarily, we ded at to the ar e. As thus formed the bracket F obviously constitutes a firm support for the brake-beam, with which it is connected in the manner presently set forth. The

Specification of Letters Patent.- Application filed October 12, 1906. Serial No. 333.591.

' approved manner without involving Patented Jan. 29, 1907.

brake-beam D is preferably reinforced and strengthened through the medium of a bar t, extending at a right angle from its middle, and. inclined truss-bars u, j oined to the beam and said bar If, and with the bracket F through a chain '22, connected to an eye w on the bar t, and a hook an, engaged with said chain 'v and having a threaded shank engaging a threaded aperture in the welded portion of the bracket and equipped above the bracket with a nut y. The strengthening bar 25' of the brakebeam supports the brake-lever L, Which is ffulcrumed at z therein, and to the lower arm of said lever is connected the brake-connecting rod M, while the up er arm thereof serves for the connection of the chain or rod (notshownlto operate the brakes.

N is my novel safety-loop, which rests under the brake-connecting rod- M and has for its office to catch and hold'or support the said rod in the event of any of the connectingpins being displaced, thus assuring the safetyof the car equipped with the brake. The brake-beam D'may, as before stated, be of any form in cross-section, and the safetyloop N may be connected to said beam in apy eparture from the scope of my invention. I prefer, however, to connect the safety-loop with the brake beam' in the manner shownthatis, throu h the medium of a shackle a,- clasping and fixed on the brake-beam, and a bolt by which the safety-loop is attached to said shackle.

P isa yoke carried by the brake-beam.

The upper' part of this'yoke serves, as illustrated, to support the lever L in its working position.

As-best shown in Fig. 1, the beam-hangers E are of loop form and are connected with the apertured lugs c of the truck through the medium of bolts R, secured in ter-pins S. In order to assist t e hangers E in the suspension of the brake-beam D and form a rigging that will not shake loose or ecome unfastened, I prefer to employ the safety-chains T, connected to the. brakebeam D through the medium of clevises U,

thebolts V of which pass throu h end links of the chains and serve to hold oth chains and clevises to the beam, and also connected to the top flange of the truck through the medium of e ebolts'W, checked by nuts X, the up er linlgs of the chains being preferably welde in the eyebolts.

place by cot- 1 ment of my invention;

'It will be gathered from the foregoin that my improvements contribute materi ly to the strength and durability of the brake-riggi and in that way rol of t e same, and it wil also be gathered that the means provided for meeting the contingency of the brake-connecting rod becomin unfastened practically eliminates the lie ility of accident from that cause.

The construction herein shown and de scribed constitutes the preferred embodibut I desire it understood that in practice such changes may be made in the form, construction, and relative arrangement of parts as fairly fall within the scape of my invention as claimed.

-aving described my invention, What I claim, and desire to secure by Letters Patent, is- I 1. The combination in abrake-rigging, of a truck-bar, a bracket having upper and lower bars joined together and fixedly con nected to upper and lower portions, respecspectively,

t-ively, of the truck-bar, a brake-beam, and a connection intermediate the bracket and the beam for hanging the latter from the former.

2.. The combination in a brake-rigging, of a truck-bar having upper and lower flanges, a bracket havingupper and lower bars welded together at their outer ends and fixedly connected to the upper and lower flanges, re-

of the truckbar; said bracket having a vertically-disposed threaded aperture in the welded portions of its bars, a bolt having a threaded shank secured in said threaded aperture, a brake-beam, and a connec-tion intermediate said bolt and beam.

3. The combination in a brake-rigging, of a truck-bar having upper and lower flanges and also having lugs. adjacent to its ends, a brake-beam, hangers connecting said lugs and the end portions of the beam, a bracket having upper and lowerbars welded together at'their outer ends and fixedly connected to the upper andlower flanges, respectively, of the truck-bar; said bracket having a vertically-disposed threaded aperture in the welded portions of its bars, a bolt having a threaded shanksecu-red in said threaded aperture, and a connection between said bolt and the intermediate portion of the brake-beam.

4. The combination in a brake-rigging, of a truck-bar having upper and lower flanges, a br'ake beam, a bracket having upper and lower bars joined together at their outer ends and fixedly connected attheir inner ends to the upper and lower flanges, respectively, of

ong the usefulness the truck-b ar, and a connection intermediate the outer portion of the bracket and the brake-beam.

5. The combination in a brake-rigging, of a brake-connecting rod, a brake-beam, and

means carried by the brake-beam for sup porting the brake-connectin rod.

6. The combination in a rake-rigging, of a brake-connecting rod, a brake-beam, and a safety-loop attached to the brake-beam and disposed under the brake-connecting rod.

7. The combination in a brake-rigging, of a brake-connecting rod, a brake-beam, and a shackle fixed on the brake beam, and a safety-loop connected to said shackle and disposed under the brake-connecting rod.

8.. The combinationin abrake-riggmg of a truck-b ar, a bracket having upper and lower bars fixedly connected to the upper and lower portions, respectively, of the truckbar, a brake-beam havin a bar extending at an angle from its midd e and also having inclined truss-bars connecting its ends and said angular bar, hangers connecting the end portions of the truck-bar and the ends of the beam, means connecting the bracket and the outer end of theangular barof the beam, a lever fulcrumed on said angular 'bar, a brakeconnecting rod connected to the lower arm of said lever, and a safety-loop connected to the brake-beam and disposed 'under said brake-connecting rod.

9. 'The combination in a brake-rigging, of a truck-bar having a top flange, a brakebeam, and one or more safety-chains interposed between the top flange of the truckar and the beam and connected to the same, substantially as specified.

10. The combination in a brake-rigging, of a truck-bar having a top flange and a bottom flange and also having apertured lugs, abrakebeam, a bracket connected to the top and bottom flanges of the truck-bar, a connection intermediate the bracket and the beam, hangers connected to the beam and the apertured lugs of the truck-bar, and safety-chains I interposed between and connectedv to the bbrake-beam andthe top flange of the truck- In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
