To all whom it may concern.- 7

Be it known that I, HENRY B. RomsoHUNc, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State oi Michigan, have invented certain new and useful Improvements in Brake-Beams; and I hereby declare the following to be a full, clear, and exact description of the same, reterence being had to the accompanying drawings, in whioh- Figure 1 is a perspective View of a trussed brake-beam embodying my invention. Fig. 2 is a detached side view of the strut partly broken'away to show the manner of obtain: ing the pull on the strut. Fig. 3 is a detached view of the extension or nose piece of the strut. Fig. 4 is a sectional View of the nosepiece on the line a: at, Fig. Figs. 5, 6, and 7 are detail views of the brake-head and the end cap or sleeve. Fig. 8 is a diagram corresponding to Fig. 5, and showing in dotted lines the manner of adj listing the brake-head. Fig. 9 is an elevation of the end cap or sleeve.

Fig. 10 is a longitudinal section of the sleeve or end cap through the center of the truss-rod opening. Fig. 11 is a transverse section of the end cap or sleeve, taken on the line '51 c, Fig. 9 and Fig. 12 isalongitudinal sectional view of asix-wheel truck and its brake-beams, illustrating the application of beams embodying my invention to 'each of three sets of wheels, the line of draft being different in each beam.

' Like symbols refer to like parts wherever they occur.

My invention relates to the con structionof brake-beams in general, but is more especially adapted to beams for use ontrucks having three or more sets of wheels, where each set of wheels is to be provided with a brake-beam, as in the case of Pullman sleepers and like heavy cars or coaches, and where, in consequence of the character of. the connection between the beams, the angle of draft varies in each beam, and that it may be readily applicable to the last-named class it has for its object the production of a reversible or universal beam. 1

To this end the invention, broadly stated, consists in the combination, with a brakebeam, of an adjustable brake-head and means Application filed January 31, i891. Scrialhl'm379fi92. (lhimodeh) for locking ofisecuring the brake-head in position on the beam after it has been adjusted to any desired angle relative to the strut or relative to the lineot draft. There are other minor features of invention, all as will here- "inafter more fully appear.

I will now proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, A indicates the beam, B its strut, 'and C the truss-rod, the Whole forming a now well-known form of trussed brakebeam, the elements of which may, for the purposes of the present invention, be any of several well-known forms thongh I prefer that the beam A should beof tubular form longitudinally slotted near its ends for the passageot the truss-rod C and notched at its ends to prevent the rotation of, the brakehead, and that the strut or post should be provided with an extension or nose piece I) with an elongated openings for the passage of the truss-rod and to relieve the truss-rod of the draft, substantially as described-in Patent No. 440,438, dated November 11, 1890, though I do not herein limit the invention thereto.

I provide the. beam hereinbefore specified or its equivalent with end caps or sleeves 1,

adapted to fit over the ends of said .beams,

end cap or sleeve 1 is a projection 3, (see' Fig. 10,) adapted to engage a notch in the end of the beam Aand prevent the rotation of the end cap or sleeve on the beam. The sleeve or end cap has a small exterior flange 4 on its inner end, which forms a seat or abutment for the head, and a longitudinal extension orprojection 5 at its outer end, which is slotted, as at 6, (see Figs. 9 and 10,) for the passage of'a clamping-bolt, which secures the brake-head to the end cap or sleeve l. This end cap I or sleeve forms a journal on whichthe brake head may ,be rotated for purposes of adj ustment.

7 indibates a brake head, preferably pro-. vided with upper and lower pivot-holes '8 and 8 for the rear suspension-rods of the beam,

the end cap,-and a bolt-hole 10, "through,-'

which and theslot 6 of extension 5 aclainping-bolt 11 may be passed to adjustably secure the brake-head to the end cap or sleeve 1.

'11 indicates the clamp-bolt, which secures the head to the end cap-sleeve; 11 3 its nut, 2c and 11 a jam-nut, used for greater security.

, B indicates the strut or post of the trussed beam, which may have a vertical slot 12 and the usual lever-pin openings 13, if desired. It is provided with perforated lugs or ears 14 5 .for the forward suspension-rod,and has at its outer end the concave seat 15 for the trussrod 0. In the open-ended slot 12 of the strut is inserted an extension piece or nose b, secured bya pin b, which passes through the o truss, and the opening a of said nose-piece,

through which the truss-rod O passes,is elongated (see Figs. 2 and 4) to allow a clearance between the truss-rodand the rear edge of theopening c, to prevent the pull coming on- 3 5 the tr'uss-rodC. The outer end-of said nose piece b is provided with two ears b b between which the draft or connecting rod is pivoted, and, if desired, the nose-piece. may

' be swelled out or re-enforced opposite the 4o pin-opening b, as indicated at b, Figs. 2 and 4:. In'Fig. 12 of the drawings are shown three beams with adjustablebrake-heads and having the characteristics hereinbefore specified, said beams applied to a truck having three sets of wheels. Each beam A'has its usual suspension-rods or rear suspension-rods, (not shown in the drawings,) its forward suspension-rods 14-, and the several beams are con- 7 nected with eachother and to the main pull- 5o rod P by a series of intermediate pull-rods 15 15 and levers 16 16 16 and it will be no ticed that the draft on each beam isat adifferent angle relative to the head, and that the-middle beam is in an inverted position. The particular arrangement or system of pull-rods and levers for operating the levers isnot material, and the system chosen for purposes of illustration is not intended to be a matter of limitation, as any other system may be used, and whatever system is used in case of a six-wheel truck the 'draft will be at a different angle on the several beams.

I wish it distinctly understood that there is no intention on my part tolimit the inven- 6 5 tion herein contained to triple gear or those having three sets of wheels, as the features.

of invention are equally applicable. to all beams. To apply my universal beam under such conditions, all that is necessary is'to loosen the clamp-bolt 11, rotate the head (seej dotted lines, Fig.8) until it has assumed a proper angleto the strut C and to the line of draft, which isepermitted' by slot 6 in extension 5 of sleeve 1, and then tighten up the clamp-bolt 11 to retain the head in the desired position.

I am aware that a beam having journal ends and loosely mounted self adjusting heads has heretofore been devised, and do not herein claim such a construction or combination; but, having herein described my invention 'and the best means 7 of carrying out the same,

known to 'me I claim I a 1. The combination, with a brake-beammf an adjustable brake-head and means forse curely locking the head to .the beam after adjustment thereof, substantially as andfor thepurposes specified.

. 2. The combination, with a trussed brahebeam, of an adjustable brake-head and -meai1s for securely locking the brake-head to .the beam, snbstantiallyas and for the pur poses. specified.

3. The combination, witir-a trussed brakebeam, of an end cap or sleeve having on its exterior an inclined surface for the clampnut of the'truss-rod and having its bore eccentric to its outer surface, and a detachable brake-head, substantially as and for. the purposes. specified.

4. The combination, with a brake-beam, of

sion on its outer end, a brake-head having a corresponding projection provided with a ,an end cap or sleeve having a slotted-exten- 5. In a brake-beam, the combination, with an end sleeve having a segmental convex projection, of a brake-head adapted to be rotated on the sleeve and having a segmental concave projection, andmeans for firmly securingthe head tofth'e sleeve, substantially as and for the purposes specified. 3

6. Ina brake-beam, the combination, with an end sleeve having a segmental convex projection, of abrake-head adapted to be rotated on the sleeve and provided with a segmental concave projection, oneof said projections provided with a slot which permits the adjustment of the head on the sleeve, substantially as andfifor the purposesspecified.
