JOHN A. WEIMER, OF LEBANON, PENNSYLVANIA.

BOGlE-TRUCK FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 717,060, dated December 30, 1902.

Application filed September 4, 1902.

To all whom it may concern:

Be it known that I, JOHN A. WEIMER, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Bogie Trucks for Railway-Oars; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to railway-cars,and has especial reference to bogie-trucks used in connection therewith on cinder-cars, hot- Inetal cars, and cars used for other purposes; and it consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a side elevation of a bogie-truck provided with my improvements; Fig. 2, a front elevation of a section thereof, the coupling being omitted; Fig. 3, a top plan view of the same; Fig. 4, a front elevation of the bolster, partly in section and on a reduced scale; Fig. 5, a vertical transverse section of the same Fig. 6, a top plan view of the cross or transom member; Fig. 7, a front elevation thereof; Fig. 7, an end view ofthe same; ,Fig. 8, a top plan and a vertical transverse section of the bearing-plate detached, and Fig. 9 a broken vertical longitudinal section of the bolster and the cross or transom member.

Reference being had to the drawings and the designating characters thereon, 1 1 indicate the side or lateral members of the truck, connected together by the cross or transom member 2 thereof, said parts being preferably of cast-steel. Said lateral members, unlike their answering or corresponding parts as heretofore constructed, are so made, preferably, as shown particularly in Figs. 1 and 3, that the wheels or their axial centers are adapted to be brought comparatively close together to more readily accommodate the travel of the latter in rounding sharp curves in the track. This is provided for mainly by the arrangement and construction of the cross or transom member 2 and the manner of effecting connection therebetween and said lateral members at points in a plane above said Wheels and within prescribed limits, as will be presently explained. Said lateral members are suitably made to receive the journal boxes or bearings of the wheel-axles and the usual springs or cushions for said journals, preferably as shown. Said lateral members are, however, widened centrally, as at 11, at their upper laterally-extended edges or surfaces for a purpose later described. Said cross or transom member, preferably cen trally downwardly-curved in its upper surface, as disclosed particularly in Figs. 7 and 9,is rectangular in its general outline in plan, with narrow arcuate portions or elevations 22 short distances inwardly from its ends and projecting somewhat beyond'boththe forward and rear edges of the upper surface of said transom member after the fashion of arcs of a fifth-wheel of a vehicle, the object of which will appear presently. Beyond said elevations or arcuate portions 22 said transom member is provided with plate-like extensions 4 4, having themselves downwardlyextending or pendent projections or flanges 44. The straight or vertical end walls or surfaces 5 of said transom member engage or fit against the inner sides of the lateral members 1 1, while the plate-like lateral portions or extensions 4 overlie or rest upon the top widened portions 11 of said lateral members, and the pendent portions or flanges 44 fit against the outer edges or surfaces of said widened portions. Said plate-like extensions are provided with,preferably, rows of holes 6,through which are inserted bolts 7, passing through registering holes produced in the widened portions 11 of said lateral members and nutted thereunder, effecting the securing together of said parts, as shown. Through holes also produced in the lower end portions or surfaces 5 of said transom member areinserted securingbolts 8 8, passing through said lateral members, additionally fastening said parts together. Said transom member 2 below its upper rectangular surface is preferably of the construction shown, having a vertical web 33, lozenge or double-Y shaped, as shown in dotted lines in Fig. 6, with the widened separated portion central thereof and tapering or converging from the longitudinal center of the transom to and integral with the vertical lower end portions 5, securing strength combined with lightness. Said transom member by reason of its construction reduces the number of fastening-bolts to the minimum, and yet is strongly and firmly held in place to the lateral members. Also the converging or tapering of the web of said transom member toward its lower end securing portions 5 provides, in connection with the overlying end securing plates 4, for arranging the carwheels comparatively close together, as above noted and for the purpose aforesaid. Also bolted or riveted centrally to the upper surface of said transom member 2 is an annularly-grooved circular plate or table 10, and above said member or part is arranged or disposed the bolster 12, having annular pendent ribs or rings 13 at its center upon the lower surface engaging, as shown, the correspondingly-grooved surface of said table or plate. Said bolster is held re'volublyin such position by a king-bolt 14, passing therethrough and through said transom member, it being suitably headed in a depression or enlargement of the opening in saidmember receiving it and held at its lower end by a pin inserted transversely through said, bolt below said member. Said bolster may also be equipped with a preferably removable rack 15, as in employing the truck or invention in connection with a car of the type or class for conveying molten or liquid cin der. Although herein shown and described as applied to this particular class of cars, said truck is equally adapted for use, as is apparent, with any character of car, as above noted. Extending forwardly from and form'- ing, preferably, a common casting with said bolster is a sleeve or pocket 16, adapted to suitably receive and permit of the proper cushioning therein of the draw bar or head 17 for connecting or coupling the truck to any suitable means or motor for its ovement, as may be required. Suitable manipulating means or lever arrangement 18, supported, preferably, as shown or otherwise, may be employed for adjusting or disposing said coupling in operatively Connecting up the same with the motor. A casting or crossbar 19, fastened or bolted to, and connecting together, the lateral or side members 1 1 near their forward ends, also serves to support the forwardly-extending draw bar or head 16 with its coupling, as greatly desired for that purpose to relieve the preponderant weight of said parts, being otherwise unsupported beyond the bolster. Said cross-bar or casting is suitably curved upwardly from under the draw-bar 16 toward or atits end portions, as shown particularly in Fig. 2, and secured or bolted, as at 20, to the top surfaces of the lateral members near their forward ends, as also seenin said figure and Fig. 3. Said support or cross-bar 19 has cast or integral with its upper surface strengthening rib-like portions or elevations 21, preferably extending from points upon each side of and short distances away from its center and clear to the ends of said cross-bar, said bar being preferably rectangular in its general contour and rectilinear or fiat, especially where it forms a support or rest for the draw bar or head, as seen in Fig. 2.

In the organization or carrying into effect my invention I employ only three castings and, as before intimated, reduce the number of bolts for connecting the parts together.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a car or bogie truck, the combination of side members, a cross or transom member connecting the side members and having end or lateral securing extensions in the plane of said transom member, and provided with vertical end members, said extensions overlying and engaging the upper edge orsurface of said side members, and said vertical members engaging one side of said side members.

2. In a car or bogie truck, the combination of side members having upper central widened portions, a transom member having end or lateral securing extensions and pendent terminals, and vertical end members, and means for fastening said lateral securing extensions to said widened portions, and said end members to one side of said side "members.

3. In a car or bogie truck, side members, in combination with a transom member connecting the side members and having end or lateral securing extensions provided with downwardly-extending terminals, the former overlying the upper surfaces of said side members, and the latter engaging said members laterally, and said transom member also having vertical end securing portions inward from said extensions.

4. In a car or bogie truck, side members, in combination with a transom member connecting the side members and having end or lateral securing extensions provided with downwardly-extending terminals, the former overlying the upper surfaces of said side members, and the latter engaging said members laterally, said transom member also having vertical end-securing portions engaging said side members, and a bolster revolubly mounted upon said transom member and bearing upon arc-shaped elevations on the last-named member.

5. In a car or bogie truck, side members, in

combination with a transom member provided with lateral securing extensions, and vertical end members, and a vertical web separated laterally in the center, converging toward each end and connected to said end members.

6. In a car or bogie truck, a transom member having a centrally-depressed upper portion or surface, a bolster adapted'to rest in the depression and revolubly mounted upon said surface, said bolster having a forwardlyextending integral pocket or sleeve adapted to receive a coupling.

7 In a car or bogie truck, side members, in combination with a transom member con- IIO or sleeve, and a cross-bar connected to said side members near their forward ends, and having a central depressed portion arranged under said pocket or sleeve, and upwardlycurved ribstrengthened end portions secured or bolted to said side members.

In testimony whereof I affix my signature in presence of two witnesses. I

JOHN A. WEIMER. Witnesses:
