I SPECIFICATION forming part of Letters Patent No. 774,673 dated November 8, 1904.

Application filed February 2, 1903. Serial No. 14;1,452. (No model-I To all whom it may concern.-

Beit known that I, EDWARD KAYLOR, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania,have invented a new and useful Improvement in VVrought-Metal Railroad-Car Trucks; and I do hereby declare the'following to be a full, clear, and exact description thereof.

My invention relates to the manufacture of wrought-metal railway-car truck-frames; and it has for its object the providing of a truckframe, simple and durable in construction, having a maximum of strength and minimum of weight. This I accomplish by forming from wrought metal the side frames or wheelpieces of a side-flanged member and attaching thereto end pieces of peculiar construction pressed and flanged to give the greatest strengthand to form integral therewith a receptacle or cap for the springs, the pedestals for the reception of the journal-box, guidebars for confining the same in position, and ameans for connecting the tie-bolt to the said pedestals, thereby forming the side frame of great strength and simplicity, capable of being strengthened at the center or any portion, as may be found necessary in practice under different requirements, without adding unnec essary weight to the balance of the frame, as will be fully described hereinafter.

Another object of my invention is to provide a suitable bolster from sheet metal, having a means for connecting the same to the side frames.

It has been found in practice that the majority of the pressed-steel trucksnow in use are defective, due to the distortion of the metal in the bending and pressing or otherwise forming the frame, and also that owing to the complicated and difficult bends necessary in these constructions of trucks but a certain'thickness can be successfully operated upon, and if the said thickness of metal is increased vadditional dead-weight is added to separate sheets.

and resist any pressure brought against the same by the brakes. The central portion ormember of the side frame may be formed of comparatively light metal, as there is a sur- ,,plus'of carrying strength at this point.

In the accompanying drawings, Figure 1 is a perspective view of. my improved pressedsteel car-truck for railway-cars, which is constructed and arranged in accordance with my invention. Fig. l issa perspective view of a pressed-steel car-truck, being a slight modification of that shown at Fig. 1.. Fig. 2 is a perspective view of the central side pieces and transoms or bolster joining the same together, the end pieces being removed there from, the said view being a part of, the construction shown at Fig. 1. Fig. 3 is a perspective view of one of the end pieces detached from the side or central member. Fig. 3? is a perspective view of one section of a modified formof the end vpiece, the same being constructed in two parts, and provided with a peripheral flange to stilfen and overcome the lateral vibration of the truck. Fig. 4: is a detailed plan view .of one of the side frames and a portion of the bolster or transoms, said view showing one of the end pieces removed therefrom. Fig. 5 is a side elevation of the same. Fig. 6 is a side elevation of one of the end pieces. Fig. 7 is an end sectional elevation of the central member, said section taken on the line X X of Fig. 4. F ig- 8 is a central end sectional ele-, vation of one of the end pieces. Fig. 9 is an end elevation of the same. Fig. 9 is a like elevation of the end pieces formed of two Fig. 10 is a detailed sectional plan view of the bolster or transom, said section taken on the line Z Z ofFig. 11. Fig. 11 is a sectional end elevation taken on the line Y Y of the same. Fig. 12' is 'a perspective view of a portion of one end of the transom or bolster, showing thefconstruction of the same. Fig. 13is a planview of a portion of the blank for forming. the end of the transom, showing by dotted lines the angles of the fold. Fig. 14 is a perspective view of guide-bars. Fig. 16 is a side elevation of a modified form of the side frame of a car-truck in which the central member and end pieces are formed integral, the side view showing the frame before bending or folding the end piece into position. Fig. 17 is an end sectional elevation taken on the line (0a of the same. Fig. 18 is a similar view to that shown at Fig. 16, except that the fold is made at the bottom of the end piece. Fig. 19 is an end elevation of the same after the fold is made. Fig. 20 is a side elevation of a side frame in which the entire side frame is formed from two pieces consisting of an inner and outer member, the one analogous to the other, except being right and left. Fig. 21 is a sectional end elevation of the same, said section taken on the line b I), Fig. 20.

To put my invention into practice, and

thereby construct a pressed-steel car-truck and side frame for railway-cars, I form from sheet metal the side frames 1, each of which consists of a central member 1, (see Figs. 2, 4, and 5,) having recessed ends 8 and overhanging portions 1, adapted to project over the top of the journal-boxes of the truck. This side or central member 1 is formed of sheet metal, preferably certain grades of steel, and by means of suitable dies provided with a deep inwardly-projecting flange 2 at the top depressed at the center, as shown at Figs. 1, 2, &c.

or in a straight line, as shown at Fig. 1, and

the said member formed with a flange 3 at the base somewhat less in width. This base-flange 3 is formed by pressing the metal to a right angle from a straight edge, leaving a small portion 4: at each end without flanges. These side or central members 1 are joined together by a transom or bolster of peculiar construction,which will be hereinafter fully described. Attached to each extremity of this central member 1 are combined journal-box bearings, spring-caps, side bearings, a' bearing for the tie bolt or bar, and a means for retaining the wearing-pieces in position, forming what will be hereinafter termed end pieces, and are attached to the central members 1 by means of a suitable number of rivets 5, placed or arranged in a position to give the greatest strength to the parts, as shown in the several views of the drawings. Each of these end pieces, such as are used in the construction shown at Figs. 1, 2, 3, 4, and 5 of the drawings, consists of a plate or sheet of metal, folded the one portion or half over the other in a manner that when slipped over the end and under the projecting portion 1 of the center member 1 the one part will be at the front and the other at the rear. This end piece may be folded at the base (see Figs. 1, 3, 4, and 5) or at the side, as shown in the modified form at Figs. 16 and 17, or the same may be formed in two separate pieces riveted together, as shown at Figs. 3 and 1. To form these end pieces 6, the sheet of metal is first blanked to the proper shape or contour and formed, by means of suitable dies, with a semicircular portion 7 in each half or section (the one semicircular portion 7 to register with the other when folded) to form the spring-cap 7 or bearing for the truck-springs and the edges of the openingv 8 flanged outwardly in each half or section to form guide bars or plates 9. These guide bars or plates 9 are braced by means of angular ribs 10, struck up by the dies at the same time as the spring-caps 7 and guide-bars 9 and the said strengthening-ribs used as a means for holding and confining the Wearing-plates 11 in position by forming in the said plates a corresponding rib or projection 12, as will be seen by reference to Fig. 15 of the drawings, and thereby preventing the said Wearing-pieces from resting upon the tie-bolt 12 or bar 38 beneath. The inner portion or section of these end pieces is formed with a flange 6, (see Fig. 3,) bent at a right angle and resting beneath the flange 2 of the side member and, if desired, riveted thereto to stifl'en the end pieces and prevent lateral vibration. These end pieces, if desired, may be formed in two sections (see Fig. 3) attached the one to the other and to the central member 1 by means of rivets 5 l7, and by means of an extension to the rear section, such as is shown at Fig. 1, the same may be attached to the transom or bolster 22 by the rivets 25, connecting the said transom with the central member 1. This end piece or section 6 may be formed plain about its periphery or provided with a flange 19, joining the guide-bar plates 9, as shown in the drawings above referred to.

The rear section of the end piece shown in the construction at Fig. 1 consists of a plate or sheet of metal provided with the guidebars 9 and spring-cap, as above described, and formed with a peripheral flange 19, extending about the edges of the entire piece, or only partially so, and is also formed with a rearwardly-projecting portion 14,bent at an angle to form a brace for the bolster 22, and the extremity 15, riveted securely to the same. This last-described construction of the end pieces gives great strength to the pedestals and rigidity to the connection between the said end piece and the bolster or transom.

At Fig. 1 I have shown the outer sections 1 in a single piece, flanges 2 at the top and ends, and having the spring-caps, guide-bars, and other portions formed in the same manner as that before described. These outside sections of the side frame are attached to the inner sections 6 by means of rivets 5, and to remove a part of the strain upon the said rivets and interlock the one section with the other -with the side frame 1.

lel channel-bars 22, having deep flanges 23 and provided'with' boxed ends for'attachment 22 is formed in the above-described manner and are joined the one with the other by means of two short sections of channel form 30, arranged in a vertical position at either side of the center. These channels 30 are formed with strengthening-ribs 31, formed in the direction of their length, and the said channels riveted securely to the channels 22. Arranged upon the top and bottom of the side channels 22 are the plates 27, riveted in position and provided with central openings for the reception of the king-bolt connecting the truck with the body of the car. The top plate 27 is fitted with a center plate 28 of ordinary con-' struction.

At Figs. 16 and 17 I have shown a modification of the side frame, which consists in forming the central member 1 integral with the end piece 36 and folding the ends inwardly along the dotted line 35, having first formed the spring-caps, guide bars or plates, &c., in the same manner as before described.

At Figs. 18 and 19 I have shown another modification of a side frame similar to that above described, except that the integral end piece 27 is folded at the base, as shown at Fig. 19 of the drawings, forming a loop on each pedestal for the reception of the tie-bar.

At Figs. 20 and 21 I have shown, a side frame having spring-caps 7 guide-bars 9, &c.

1 formed froin'two pieces, the one analogous to the other, except that they are right and left, and the two thus formed arranged the one within the other, as will be seen by reference to Fig. 21 of the drawings, and in Fig. 9 I have shown the end pieces formed of separate sheets of metal and connected to the central member 1. Y

It is obvious that several other modifications of my invention may be made without departing from the spirit of the same. Therefore I do not confine myself to the exact constructions shown and described.

Having thus described my invention, I claim 1. An end piece for side frames of a railway-car truck formed of two separate sheets of metal and joined together.

2. A wrought-metal side frame for cartrucks, consisting of a center piece or member formed of a single flanged sheet or rolled section, and end pieces formed of two separate sheets of metal so as to make said end pieces of double thickness, said center and end pieces being joined together.

3. An end piece for side frames of a railway-car truck formed from two separate sheets of metal and joined together, and an extension on the rear portion of said end pieces which is bent at an angle and attached to the bolster or transom.

4. An end piece for side frames of a railway-car truck formed of two separate sheets of metal and joined together, and a peripheral flange on said end pieces.

5. An end piece for side frames of a railway-car truck formed of two separate sheets of wrought metal and joined together, said end pieces provided with recesses near the base to form openings for the reception of the tie bolt or bar.

6. In a side frame for a railway-car truck, a central flanged member provided with extensions projecting over the journal-box openings, and end pieces formed of doubled thickness of sheet metal attached to said extensions. 7. In combination withthe side frame of a railway-car truck of end'pieces formed from doubled sheets of wrought metal, said end pieces being riveted or joined together and provided with integral spring-caps, guide-bar plates, and bearings for the tie bolt or bar.

8. In combination with a wrought metal car-truck, of a bolster or transom formed of two channel-sections arranged side by side and attached together, and boxed ends on the extremities of said sections formed by cuttingthrough the metal and folding the same to form flanges on said sections and boxed ends, said flanges being bolted together.

9. A side frame for a railway-car truck formed of outer and inner sections, andribs and depressions formed on each of said sections, one to register with the other for relieving the strain upon the rivets joining the sections or parts together. i

In testimony whereof I, the said EDWARD KAYLOR, have hereunto set my hand.
