WILLIAM P. BETTENDORF, OF DAVENPORT, IOWVA.

SPECIFICATION forming part of Letters Patent No. 679,494, dated July 30, 1901. Application filed December 27, 1899. Serial No. 7ll,764- (N0 model-l To (tZZ whom, it may concern:

Be it known that 1, WILLIAM P. BETTEN- DORF, a citizen of the Unit-ed States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Body and Truck Bolsters for Railway-Oars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

The object of my invention is to provide a body and a truck bolster for cars made from a novel form of rolled-steel beams, which is so constructed as to form a truss capable of withstanding the draft strain of the car, as-

well as supporting the maximum of weight and equally distribute the same, while at the same time making a very light bolster at a minimum of expense. This I accomplish by the mechanism hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 shows a side elevation of about two-thirds the length of the body and truck bolster in their relative positions, showing the portion of the half, the end of which is broken away, in longitudinal vertical section. Fig. 2 is a transverse vertical section taken on dotted line 2 2, Fig. 1. Fig. 3 is a plan view of my improved body-bolster inverted. Fig. 4 is a plan view of my improved truck-bolster. Fig. 5 is an end view of said bolster in the relative position shown in Fig. 1. Fig. 6 is a transverse view of a cut-off end of the body-bolster. Fig. 7 is a perspective view of a broken-away end of the truck-bolster. Fig. 8 is a transverse section of the body-bolster, taken on line 8 8 of Fig. 5. Fig. 9 is a perspective view of a rolledsteel beam such as is employed in the conand a lower section of a peculiarly-constructed rolled-steel beam, so arranged that their sides are bounded by the same vertical planes. This rolled-steel beam consists of a flat plate a of suitable Width and thickness, which are the same throughout the entire length of the beam. Between each longitudinal side of this beam and the center of width thereof it has projecting at right angles from one of its broad surfaces two corresponding parallel Webs b, and it is provided with longitudinal beads 0, preferably on the same side as that from which said webs project, the outer contours of which are preferably next and flush with the longitudinal sides of the beam.

The upper section A of the rolledsteel beam ab 0, used in making the body-bolster, is straight its entire length and is placed so that its webs project downward, whereas the lower section B of said rolled steel beam, which is placed so that its webs project upward, has its central portion arranged parallel to said upper section A and its end portions on either side of said central portion bent toward said upper section, so that the edges of its longitudinal webs I) come in contact with the edges of the webs b of said upper section at a point about ten or twelve inches from the ends of the bolster, from which point the end portions of said lower section are so bent that said end portions are parallel to section A and have their meeting edges in contact therewith, as shown.

The parallel central portions of the upper and lower sections A and B: are connected by rectangular vertical plates O O, which are secured, preferably, to the inner vertical surfaces of the webs b 5 thereof, coming in the same vertical plane, by transverse bolts D. These plates (J may be perfectly flat their entire length and breadth; but I prefer to make them of short sections of rolled-steel beams, having their side edges correspondingly bent at right angles thereto to form flanges cl cl. Plates 0 are also provided with longitudinal parallel ridges e e, the sides of which next the flanges cl are at right angles to the broad sides of said plate, and each ridge is so located that when the plate is socured to the webs b of the sections A and B the edges of said webs bear against the flat sides of said ridges and the flanges d (1 will bear against the adjacent portion of the broad sides of the said sections A and B. Plates 0 are secured to the webs of the upper and lower sections by transverse bolts D, as stated. I prefer to use four of these bolts D for securing both the upper and lower side portions of these plates 0 to sections A and B and to place them at equal intervals apart in the same horizontal plane. The end bolts of the series have the portions thereof coming between the plates 0 pass through spacingsleeves f, the length of which are such that when the bolt-heads are swaged the plates 0 are securely clamped between the heads of the bolts D and the ends of the spacing-sleeves. These sleeves may be of the same diameter throughout their length; but I prefer to provide their ends with flanges f, one side edge of which is elongated in suitable manner and has its outer end out off straight at right angles to the major axis of the same, so that when in use such straight edge will bear against the flanges ofthe plate 0, as shown.

The two intermediate bolts D of each series extend through sleeves g, which latter are the same in every substantial respect as sleeves f, excepting that they are connected at about their centers of length by a cross bar 9, through which the vertical guide-opening for the king-bolt is made. Plates 0 and the individual and siamese sleeves f and g, when united by the bolts D to the upper and lower section A and B, make a very strong central filler for the bolster, which latter when connected to the sill-timbers and other parts of the car is amply able to withstand the draft strain of the car, whichis transverse thereto. The central portion of the bolster is further reinforced to withstand this draft strain by the plate of the male bearing E, secured to the under surface of the lower section B by rivets 2 2, passing down through the same near each side and through plate 01 thereof between its longitudinal sides and the webs b of the same.

The ends of the sections of beam A and B, composing the body-bolster, are secured together on each side by vertical bolts F B, which pass vertically down through the marginal portions of plates a thereof between the webs b and the heads of said sections, and by vertical bolts G G, passed vertically down through plates at of said upper and lower sections at a point near the end of the bolster and just inside of the webs b of the same. These vertical bolts F and G may be passed through the two sections at any other point near the ends of the bolster, if desired; but I prefer them to be placed as indicated, because they thus afford greater strength and rigidity to the bolster and at the same time can be utilized to assist in holding the end' plate K in place, as will hereinafter be more fully explained.

I could confine myself to the use of the bolts F and G alone to secure the ends of the upper and lower sections of the bolster together. I prefer, however, to use a suitable casting in conjunction with these bolts, which will not only reinforce the bolts a of these sections at the point where said bolts pass therethrough, but will also clamp the same, so as to resist both the transverse displacement and longitudinal strain of said sections.

'This casting consists of a key h, the contours of which are preferably rectangular and is of such length that it can just pass through corresponding rectangular recesses in the adjacent meeting edges of the webs of the sections. This key connects two substantially corresponding rectangular plates 2' and j, one of which is adapted to bear against the outer vertical surface of said webs and the other of which is adapted to bear against the inner vertical surface of the webs next the recess in which said key is seated. These plates 1' and j are of substantially corresponding dimensions, and the outer one ext-ends horizontally toward the center of the bolster a short distance, and has made integrant therewith and arranged at right angles thereto a vertical 1 sleeve, which is so located that the bolts F can pass therethrough, and is of such vertical dimensions as to reinforce the plate at where said bolts pass through the same. The plates j, made integrant with the inner end of said scribed by the edges of which are such as to follow the contours of the ends of the upper and lower sections of the bolster when the same are secured together. This end plate is secured to the end of the bolster by means of lugs o 0, projecting inwardly therefrom at a point about the middle of its height and so that the ends of the same will enter between the knuckles m m of the platej, so that the bolts G, when extended down through the plates at of the upper and lower section and said knuckles can pass through vertical openings in the same and thereby hold said end plate in place. This end plate is made to assist in the holding of the upper and lower sections together by having its edges provided with inwardly-projecting flanges which lap over and bear against the sides of the ends of said sections, substantially as shown.

The truck-bolster also consists of an upper section B and lower section S of the rolledsteel beam a b c, the central portions of which are connected by vertical plates 0 similar in every substantial respect to plate 0, hereinbefore described, except that it is slightly wider, so as to hold the central portions a little farther apart than as shown in the bodybolster. In the truck-bolster the end portions of each the upper and lower sections thereof are bent or inclined equally toward each other until the edges of webs h 1) thereof meet at a point about, say, twelve inches from the ends of the bolster, whereupon they are again bent so that from said point of initial contact to the ends the plates a of said sections are parallel and the edges of the webs Z) thereof remain in contact. These end portions of said upper and lower sections are secured together by vertical bolts 0" and s, which, preferably, are passed through suitable bolt-holes in plate a between the webs Z) and beads 0 thereof. These bolts r and 5 may be independent of the guide-blocks V V, but I prefer to use them in conjunction there with.

The guide-blocks V are constructed so as to provide the usual vertical guide-channel 5 in their outer surfaces, and on each side of this channel they are provided with lugs 6 6, which are so formed that their flanged end edges bear against the outer vertical surfaces of the webs Z) and are provided with vertical knuckles 7 8, down through which bolts 1" and s extend. The knuckle 8 next the end of the bolster has its center of length cut away, and between the divisions thereof I insert the adjacent lug 9 of the end plate 10. This end plate 10 is similar in function and construction to the end plate I of the body-bolster; but its fastening-lugs 9 extend inward from its side edges and lap against the outer surface of webs 1) between lugs 8 instead of against the inner surface of said webs.

The body of the guide-block V projects inward at a point about in transverse alinement with the center of width and height of the guide-channels 5 thereof and is so formed that its inner end is preferably rectangular in cross-section and forms a key 12, which enters the rectangular opening l3,made by making corresponding recesses in the webs b of the upper and lower sections at such a point that when the edges of the webs of said sections are brought together said rectangular opening 12 results.

The end plate 10 reinforces and strengthens the ends of the bolster in a transverse direction, and the keys 12 of the guide-block prevent the longitudinal displacement or shearing strain of the two sections and re move a great deal of said shearing strain that would otherwise fall on the bolts 1" and s.

In order to complete the bolsters hereinbefore described, I secure to the under side of the body-bolster by rivets or bolts extending through the lugs thereof and through the plate a of the under section at points preferably between the webs and the longitudinal sides thereof and the segmental side bearing NV, and I secure to the upper surface of the truckbolster in the same manner the side bearing U. In order to economize, I prefer to utilize the bolts 7' used in the trnck-bolsterto secure the upper and lower sections together and also to fasten one end of the guide'block thereto in securing the said side bearing U to the truck bolster. This is easier accomplished by making the basal lugs on one side of said side bearing U of such dimensions that said bolts 4" can be passed through the bolt-opening therein.

While I much desire the use of the heads 0 in the rolled-steel beams from which the upper and lower sections of the bolster are made, yet it is obvious that said beads might be dispensed with. These beads serve to greatly strengthen the beams to resist the side or transverse pressure thereon and are particularly used in the beams used in construction of the body-bolster.

I do not wish to be confined to the exact means hereinbefore described and shown to fasten the ends of the upper and lower sections of my improved bolsters together. Skilled workmanship would suggest a great many other means and devices for accomplishing this purpose, especially when the peculiar means employed by me in the construction of said bolsters are disclosed.
