SPECIFICATION forming part of' Letters Patent No. 715,518, dated December 9, 1902. Application filed December 13, 1901. Serial No. 85,766. (No model.)
T all whom it may con/cern,.-
Be it known that I, THOMAS H. SIMPSON, a
citizen of the United States, residing at Deof brake-beams, and has forits object a brakebeam of superior simplicity, economy, and eficiency.
I carry out my invention as hereinafter described and claimed, and illustrated in the drawings, in which- Figure 1 is a side elevation embodying features of my invention. Fig. 2 is a detail view of one end of the beam, illustrating a step in the process of manufacture. Fig. 3 is another detail view of one end of the beam, illustrating another step in the process of construction. Fig. 4t is a View in section on the line 4: 4, Fig. 3. Fig. 5 is a detail View in perspective. Fig. 6 is a View in detail, illustrating a modification inthe construction of the beam; and Fig. 7 is a view in section on the line 7 7, Fig. 8, Fig. 8 is a detail View, in side elevation, illustrating one form of my invention. y
My invention more particularly has reference to a brake-beam having its ends reduced.
In the drawings, a represents any desired standard rolled beam. In Figs. l to 4 and 6 to 8 a standard I-beam is shown,provided with upper and lower ianges b and c and a web d. In Fig. 5 an ordinary deck-beam is shown, having a web d. I do not limit my invention to any particular form of beam.' Y
The chief feature of my invention relates to a narrowing or reducing of the ends of the beam to provide for a sufficient movement of the beam when in position, as for inside hanging.
It is well understood that ordinary standard rolled beams are usually too wide at the extremities for inside han gin g,in consequence of which it has been found desirable and necessary to reduce the extremities of the beam in order that it may be properly applied. To accomplish this end, myinvention contemplates slitting or kering the web of the beam longitudinally thereof at the extremity of the beam in' any desired form and forcing the adjacent portions of the beam inward the one toward the other. In Figs. l to 5 I have shown and illustrated a construction wherein the web at the end of the beam is kerfed or cut away, a wedge-shaped or triangular portion of the web being removed, as indicated in Fig. 2 at e.l The adjacent portions of the beam on the opposite sides ofthe kerf (indicated by the numerals l and 2) are then forced the one toward the other the desired distance. In Figs. 6 and 8 the extremity of the web is slitted, as indicated at f, Fig. 6. To facilitate the inward forcing and reduction of the parts l and 2 the web is preferably perforated, as shown at 3. In the form shown in Figs. 6 and 8 the web is not cut away; but the adjacent' parts l and 2 after the web is slitted, asat f, and perforated, as shown in Fig. 6, are caused to overlap one another as the said parts are forced inward. In the form illus- .trated in Figs. 1 and 5 the edges of the parts l and 2 are simply forced together, as indicated at the meeting line 4. The overlapping of said parts is shown in Figs. 7 and 8. The overlapping edges are also perforated, as shown at g, to receivea rivet passed through the brake-head. Where the web is gered, as indicated in Fig. 2, and the adjacent parts are brought together to reduce the end ofthe beam, the brake-heads (indicated at hh) may surround the adjacent extremity of the beam to hold the parts together, the brake-head being secured in place in any suitable manner. Where the parts l and 2 are overlapped, a rivet 5 may be passed through the brakehead and through the overlapping parts to hold them in place. While I prefer to force both of the parts laterally adjacent toI the kerf inward, my invention contemplates the forcing inward of only one of said parts asA coming within its scope. The kerf may be simply a slit or it may be of any desired form. In certain other processes of reducing the IOO ends of the brake-beams it has been necessary to heat the beam and re-form it in a heated condition. Thisdrawsthetemperofthebeam and necessitates added expense in the manufacture of the beam. Myinvention, however, may be accomplished without heating the beam, as the web may be kerfed of desired form and one or both of the parts laterally adjacent thereto maybe forced inward under suitablepress. Bydispensingwiththenecessity of heating the beam it may be more economically reduced at its extremities than Where heat is employed, while also the temper is retained in the metal.
If it were desired, one of the parts laterally adjacent to the kerf might be left straight, the other laterally-adjacent part only being pressed inward either to meet the edge of the corresponding portion or to overlap it, as may be desired.
The brake-head applied to a beam having its parts overlapped may simply be forced over one of the flanges of the beam and riveted to the overlapping parts of the beam. Where the brake-head surrounds the end of the beam it may be riveted in place, as indicated at 7c, to one of the laterally-adjacent parts.
What I claim as my invention isl. A commercially-rolled member for brakebeam having top and bottom anges, whose web is divided at the ends into two portions of substantially equal length and is provided with an enlarged perforation near the ends of said beam and from thence to the end thereof is bent at an angle to the axis of the beam whereby seats are formed for brake-heads at the ends of said beams; substantially as described.
2. A brake-beam provided with a web, the extremity of the web being longitudinally kerfed, forming adjacent parts of equal length on opposite sides of the kerf, said parts pressed inward the one toward the other to form a reduced end of the beam, said beam having in combination therewith abrake-head, and a rivet simultaneously uniting said brakehead and the adjacent parts of the beam to hold the parts of the reduced end of the beam and the brake-head in place.
3. Acommercially-rolled I-beam for brakebeam whose web is divided at the ends into two portions of substantially equal length and is provided with an enlarged perforation near the ends thereof and from thence to the end is bent at an angle to the axis of the beam whereby seats are formed for brake-heads at the ends of said beams; substantially as described.
4. A commercially-rolled member for brakebeam whose web is divided at the ends into two portions of substantially equal length and is provided with an enlarged perforation at the inner ends of said divisional line and from thence to the end thereof is bent at an angle to the axis of the beam whereby seats are formed for brake-heads at the ends of said beams; substantially as described.
5. A commerciallyrolled member forbrakebeams whose web is provided with a circular perforation and from thence divided to the ends of the beam, said divided portions being bent at an angle to the axis of the beam to provide a gradually-increasing overlap in the web to the ends of the beam; substantially as described.
6. A commercially-rolled member for brakebeams, having top and bottom anges, whose web is provided with a circular perforation and from thence divided to the ends of the beam, said divided portions being bent at an angle to the axis of the beam to provide a gradually-increasing overlap in the web to the ends of the beam; substantially as described.
7. A commercially-rolled I-beam for use in a brake-beam, having top and bottom flanges, whose web is provided with a circular perforation and from thence divided to the ends of the beam, said divided portions being bent at an angle to the axis of the beam to provide a gradually-increasing overlap in the web to the ends of the beam; substantially as described.
S. In a brake-beam, a commercially-rolled member whose web is kerfed at the ends, the portions of said web surrounding said kerf forming an overlap to the ends of said beam, and a brake-head riveted thereto, the rivet therefor uniting the overlap portions of the web and holding said brake-head in position; substantially as described.
9. A brakebeam provided with overlap ping web portions at the ends thereof, brakeheads, and rivets simultaneously securing said brake-heads to said beam and holding the reduced ends of said beam in place; substantially as described.
l0. A brake-beam composed of a'commercially-rolled member provided with overlapping web portions at the ends thereof, brakeheads, and rivets simultaneously securing said brake-heads to said beam and holding the reduced ends of said beam in place; substantially as described.
11. A brake-beam composed of an I-beam provided with overlapping web portions at the ends thereof, brake-heads, and rivets simultaneously securing said brake-heads to said beam and holding the reduced ends of said beam in place; substantially as described.
In testimony whereof I sign this specification in the presence of two witnesses.
