Application filed ms 10,

To all whom it mag concern:

Be it known that I, SAMUEL I-I. TERRY, residing at the city of St. Louis, State of Missouri, have invented a new and useful -Iinprovement in-Brake-Beams, of which the fol full, clear, and exact description,

drawings, forming a part of this specification.

My invention relates to an improved brakebe'am constructed in acheap, strong, and due rable manner, and which possesses features of novelty hereinafter specifically described and claimed. Y Itet'erring to the drawings, trates a top or plan view of: my improved beam, II shows a side View of the same. Fig. III is a detail section of the end of the taken on the line III III of Fig. I. Fig. IV is an end view of the Q01". lar and swivel fitting over the-beam, takenon line IV IV of Fig-1. Fig. V isa detail view showing how the sides of thebar are joined together. Fig. VIis'a cross-section of the beam. Fig. VII is a sideview of the collar and swivel. Fig. VIII is a cross-section of the beam, showing how the pieces thereofmay be bound together by a band or bands. Fig. IX is also a cross-sectionof a modified construction, showing howthe pieccsof the bar may be bound together by'bolts. Fig. X

shows how the piates may be fastened together by rivets.

'1 represents the bar of the'bearn, on each end of which is a shoe-frame 2, held to the beam by means of the head 3,'each head being attached to the beam by any suitable means.

I, VIII, IX, and X." They are held in place byineans of the edges. thereof being made with alternate recesses 5 and projections 6,- the projectionsfo'n one piece being adapted to fit. into the recesses of the other. These projections are considerably longer than the thickness of the steel, and the part that thus extends over is bent down onto, so as to overlap, the adjoining plate, and thoroughly fas tral collar7, held inplace by the bolt 13.

I fits around the beam and serves 'the addition'at purpose of holding the plates together; Fig'l VII shows a modifiedform of this dollar,

in which the upper portion of 7 is spread out to give the device additional strength.

Sis the swivel to which 'is'attached the brake-lever. 9 are binding-bands, passed around thebar to hold the parts more firmly together. 1O, Fig. IX, is a. bolt provided with shoul-- ders 11, likewise for the purpose of holding the bar-plates more firmly together.

Y 12, Fig. X, shows another modified form,

in'w'hich the bar-plates are held together by rivets. 1

. Iprete'rto construct the beam of sheet-steel of from slightly wider and higher in the center than at the ends, I x My construction .f uq'nis'hes a beamof very light weight, of great strength, and inexpensive tomanufacture; flhe bearn'may be constructed without the bands" 9, as the plates are securely locked together without them.

I do not limit myself to the use of sheet stee" in the construction of my beam, as any other suitable material maybe used; nor do. I limitmyself to the use of the notched fasten'ing on all three or. the joints. The beam may joints notched, whil'e the third remains unnotched, the plates thereof being held together by the bands 9 or collar 7. Y

I claim as my invention- 1. A brake beam formed of three plates suitably supported andisecured togetherat their meeting edges, and-binding bands surrounding said plates, substantially as and for the purpose set forth.

2.,A brake beam composed of three plates,

No. 10 to No. 13gage. I make it be construe-ted with only the two lower each .plate being formed. with alternate tongues and recesses along their meeting and securedftogetherby having the tongues on one plate enter therecesses in an adjacent plate and to have the said tongues bent over and overlap on said.. plat e,.substarr tiahly as shown and described";
