RAILWAY-TRUCK SIDE FRAME.

Application filed February 10, 1912.

To aZZ whom. 15 may concern Be it known that I, ALoNzo L. Has'rixos, a citizen of the United States, residing at Chicago, in the county of Cook and State ot Illinois, have invented certain new and usetul improvements in Railway-Trnck Side Frames, of which the following is a specification.

My invention relates to railway truck side trames and refers particularly to that class ot` side :trames built up of structural forms.

Among the important objects of the invention are to provide improved construction and arrangement; to provide improved method and procedure for uniting various parts and structures into a con'iplete side frame structure; to provide such construction and arrangement that the various parts for the complete structure can be readily worked into t'orms; to provide such construction and arrangement that the `various formed up parts can be finally intimately secured together by means of a single die structure and a single operation thereof; to provide such construction and arrange ment that the parts can be readily secured together by spot welding; and in general to provide a more simple and more etlicient process or procedure for producing the structure.

The various features of my invention can be clearly understood by reference to the accompanying drawings, in which- Figure l is a side elevational view of upper and lower chord members in embryo form, the chord being broken away, Fig. 2 is a side elevational view showing the chord `members secured together' and a spring plank and bolster mechanism supporting trame in embryo liorm held between the chord members, Fig. 3 is a sectional view taken on plane 3 3, Fig. 2, Fig. it is a sectional view taken on plane L /l, Fig. 2, Fig. 5 is a ltop view o't the structure shown in Fig. Q, Fig. (l is a side elevational view like Fig. 2, but showing the spring plank and bolster mechanism supporting trame in iinal form, Fig. 7 is a top view of the structure in Fig. t3, Fig. 8 is a sectional view taken on plane 8 3, Fig. G, Fig. 9 is a sectional view taken on plane 9-9, Fig. S, and Fig. l() is a sectional View taken on plane 10-10, Fig. s.

The procedure in constructing improved side trames is as follows: Two lengths of Specification of Letters Patent.

beam ot' suitable cross-section are lirst bent to 'Form the upper and lower respectively compression and tension chords C and T oi the trame. Any :torni oit' beam can be used, but on account oit? their lightness and strength beams oit T-seetion are preferred. The length 'tor the upper chord is bent to provide a central horizontal section l5, intermediate downwardly inclined sections 1G and 1G', and the end horizontal sections 17 and 17. The beam tor the lower chord is bent to provide the central horizontal section 1S, the intern'lediate ulnvardly inclined sections 1t) and 19 and the end horizontal sections 20 and 20.

To itorm the inclosing frame for the spring plank and bolster' mechanisms a length of channel beam is bent into the rectangular frame F with the flanges thereof extending outwardly. '.lhis trame is then applied between the upper' and lower cord stiriletures (.1 and ',l, the horizontal section 15 o1 the upper cord then resting against the :trame F between the upper flanges Q1 and 22 thereof, and the horizontal section 18 of the lower cord rests against the bottom web ot' the trame F and between the `langes 23 and 2l', the outer ends 17 and 20, and 1T and Q0 of the chords then abutting. These abutting ends are now heated and worked and welded securely together so that the frame F is securely clamped between the chords the ends being shortened during working and thereby thickened so that the finished structure has ends ot substantially rectangular ttorm as shown in Fig. 2. The middle part oit the structure is now sutliw eiently heated for die operation and is then inserted between die members and the flanges 2l and and 223 and 24. projecting beyond the chord sections 15 and 1S are detlected over and against the outer :faces ot these sections, and during the same opeation the llanges 9.5, 2G and 52T, Q8 of the side meml'iers oit the trame F are bent over against their supporting webs. After the die treatment the `trame F and the chords can be further secured together by spot welding, and likewise the

flanges

25, 26 and QT, 28 can be spot welded to their supporting webs, so that strong' and rigid vtuftical sl'lpporting walls result 'tor accon'nnodating the spring plank and bolster' mechanism.

As illustrated in Fig. 5, the edges of the flanges ot' sections 'l5 and 18 of the upper and lower chords are preferably cnt away llt) S2: Loeeio a distance corresponding to the thickness of the flanges of the frame F, so that when these flanges are turned over the frame F will be securely locked aga-inst. longitudinal displacement on the chords and the structure will also present a more finished appearance. rlfhe length of the upper and lower walls of the frame F is preferably suflicientlly greater than the lengths of the sections 15 and 1S respectively, so that during the die process the ends of the upper and lower webs of the frame F will be drawn against the outer faces of the

inclined sections

16, 16 and 19, 19 as the upper and lower ends of the

flanges

25, 2G and 27, 2S are drawn inwardly against their supporting webs, the bends between the horizontal and inclined sections of the chords being thus securely pocketed and clamped at the corners of the frame F. A very rigid structure thus results from ordinary stock material, and no bolts, rivets or other extraneous fastening members are necessary. The structure has also great strength, yet is very i light. y

Then the side frames are utilized in t-he truck a spring plank will engage at its ends at the lower part of the frame F and between the 4side walls thereof, and the truck bolster will extend at its ends into the frames F of the opposite side frames, and the side grooves usually provided therefor will receive the side walls of the frame F. In order that the truck bolster can be inserted into the frame into engagement with the upper ends of the sidewalls thereof the lower ends of these side walls are deflected outwardly, as indicated at 29 and 29, Fig. 2. These deflections are preferably formed in the frame F during formation thereof, and such deflections provide the

opposed grooves

30 and 30 into which the ends of the truck bolster are first inserted and the bolster then raised so that its side grooves will receive the upper ends of the side walls of the frame F, as is well understood in the art. It is also customary to provide brake hanger brackets on the side frames. In my construction such brake hanger brackets are accommodated in the following manner: The bases of the

brake hanger brackets

31, 31 are inserted through slo-

ts

32, 32 formed inthe flanges of the vertical walls of frame F. As shown, the flanges 2G and 2S are thus provided with slots, the brake hanger bracket ends extending horizontally through these slots and abutting against thebases of the

opposite flanges

25 and 27 and against the webs between the flanges. The brake hanger brackets when thus inserted are preferably in their embryo blank form, so that their outer ends may extend through suitable openings provided in the die members, so that the operation of the die members in deflect-ing over the flanges of the frame F will not be interfered with. After the die operation the flanges will be securely clamped against the brake hanger blank bases, as shown in Figs. 8 and 10, and to insure greater strength and rigidity spot welding may be resorted to. `After the die operation the outer ends of the brake hanger blanks are deflected and bent into the iinal form shown in Figs. 8 and 1.0.

In order that the brake hanger brackets may not interfere with the free engagement of the truck bolster with the frame F, each brake hanger blank is given a sharp reverse bend 33 where it enters its slot 32 or 82, and the slot is cut through the Bange at a distance from its supporting web so that thc inner end of the brake hanger blank will abut against the web, but tlie outer end will be at a sufficient distance away from the inner face of the web as to be clear of the truck bolster. Means are also provided for locking the spring plank against the base of frame F and between the side walls thereof. The opposite flanges of the respective side walls of frame F have near their' lower ends slots 34, 85 and B-, 35 respectively. Through slots 34: and 35 a flat bar 8G is inserted, and through the slots 34, 35 a similar bar 36 is inserted. rlhese bars extend a distance beyond each side of the frame F and abut against the webs of the respective flanges, and in order to have the outer ends of the bars flush with the inner faces of the side walls of frame F and flush with the sides of the spring plank between said walls the outer ends of the bars are defiected inwardly, as clearly shown in Figs. 7 and 9. The projecting ends of the bars then extend through suitable openings in the die members, and when the die members are brought together the respect-ive flanges are securely clamped against and about the middle sections of the bars, and further strength is added by spot welding. When the spring plank is inserted between the side frames the outer endsv of the bars are spot welded to the spring plank sides or bolted or riveted thereto. rlhus a single die structure and a single operation thereof suflices to assemble the various parts and secure them together. The cords C and T are applied to the frame F and the brake hanger bracket blanks and the spring plank supporting bars are inserted in their respective slots and then the built up structure is treated between the die members, during which die operation the flanges of frame F are securely drawn and clamped about the chords C and T and about the brake hanger blanks and spring plank supporting bars. A simple auxiliary operation will serve to form up the outer ends of the brake hanger blanks. The opposite ends of the chords C and T may be secured together, preferably by welding after the chords have been applied about the frame F. These chord ends need not, however, be connected together at this time, but, Yt'or example, could be connected together during the operation of securing journal box structures thereto. The resulting side structure is extremely rigid and strong, yet is very light, and its construction is very simple and inexpensive, as ordinary stock beams and material can be utilized, and only a single simple die structure is necessary for iinal intimate assembling of the various parts.

I do not of course desire to be limited to the precise construction, arrangement and procedure described, as changes and moditications are of course po-ssible which would still come within the scope oit the invention, and

I therefore claim the following:
