ARTHUR B. BELLOW S, OF PITTSBURG, PENNSYLVANIA.
BRAKE-BEAM. I
-.:5PECIF0ATION forming' part of Letters Patent No. 698,788, dated'April Q9, 1902.
Application filed September 27, 1901. Serial No. 76,762. (No model.)
To all whom it may concern.-
Be it known that I, ARTHUR B. BELLOWS, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Brake- Beam, of which the'following is a full, clear, and exact description, reference being bad to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a side elevation showing the method of forming my improved brake-beam. Fig. 2 is a top plan view of the finished brakebeam. Fig. 3 is a similar view showing a modified form. Fig. 4 shows my preferred mode of attachingthe brake-rodfulcrum. Fig. 5 is a cross-sectional view on the line V V of Fig. 4. Fig. 6 is a cross-section of the end elevation of the brake-beam, showing the attaching of the brake-shoe.
My invention relates to the class of brakebeams, and is designed to provide a simple and strong construction therefor which can be easily made from commercial shapes and which shall be strong and efficient and also adapted to the limited space arranged to receive it.
In the drawings, referring to Fig. 1, 2 represents a section of a rolled channel having inner and outer flanges 3 and 4. In forming my improved brake-beam the web of the channel is cut awayon each side of the center in U shaped form, as shown at 5 5, and from the ends of the section the web is cut away in triangular form, as indicated by the lines a b. The parts of the web extending parallel with the lines a b are bent at right angles to the plane of the web and opposite to the flanges 3 and 4, thus forming inner flanges 6 6. The side portions of the section thus formed are then bent toward each other, thus bringing the flanges 6 6 together and closing the outer ends of the U-shaped slots. The ends of the web are preferably pressed to form parallel portions 7 7 at each end of the beam to provide for attachment of the brake-heads, and the flanges 6 6 are secured together by rivets, as shown. The sides of the section may both be bent inwardly, thus bringing the joint between the'inner flanges in line with the 1ongitudinal axis of the beam, as shown in Fig. 2, or one flange may remain in its original position, the opposite portions being bent down, as shown in Fig. 3, the flanges 6 then being at one side of the center line.
In attaching the brake-rod fulcrum I may provide a bracket 8, such as shown in Fig. 2, "and which isriveted to the lower flange of the channel and is provided with a lip 9, riveted to the web, the ears 10 1O projecting outwardly, as shown; but I prefer to rivet this bracket to the web of the beam, as shown in Fig. 4, and to allow the'passage of the brakerod I provide a central slot or hole 11, which is cut through the central part of the web, the ears 10 extending laterally at an angle from the bracket, as shown. This gives a very simple and neat construction and does not injure the strength of the beam. The brake-shoe 12 is secured to the, end of the beam by bolts 13, extending through the flanges 3 and 4 and through a separatingsleeve 14, arranged between them, as shown in Fig. 6.
The advantages of my invention result from the cutting and bending out of the web into flanges, which are secured together, and further from the cutting of the hole through the center of the beam for the passage of the brake-rod, and also from the compactness,
strength, and cheapn'ess of the construction.
Changes may be made in the form of the shape and the slots or cuts, as well as in the bending and the attachment, without departing from my invention.
I claim 1. A brake-beam consisting of a flanged shape having parts of its web cut and bent outwardly to form-flanges; substantially as described.
2. A brake-beam consisting of a rolled chan nel having openings out between the center and its ends, and web portions cut and bent outwardly between the openings and the ends,- the outwardly-bent portions forming flanges which are riveted together in pairs; substantially as described.
3. A channel section having openings formed at each side of the center and web portions cut and bentin a direction opposite to the channel-flanges, forming flanges which are riveted together substantially as described.
4. A brake-beam formed of arolled section,
having openings on opposite sides in its web, and Web portions between said openings and its ends which are bent outwardly in a direction opposite to that of the channel-flanges, and brake-shoe carriers secured by bolts extending through the channel-flanges; substantially as described.
In testimony whereof I have hereunto set my hand.
ARTHUR B. BELLONVS.
