To all 'whom it may concern:

Be it known that-I, RALrH H. Bnaon, a

citizen of the United States, and a resident y which the following isa specification.,

My invention relates to. railway. cars, and particularly to that type of electric railway .car which is` designed to be operated by storage batteries. In Jorder that a railway car maybe successfully operated by' storagebatteries, it is essential that the weight of the caritself be reduced to a minimum con.- sistentwith strength and rigidity.

The object of my invention is toiproduce a car which combines a maximumA of strength 'and rigidity with a minimum of weight. I have accomplished` this result by employing a supporting frame structure of novel design and which constitutes a radical departure from the `car frame strucltures now in use.

My improved car frame is an inte al structure made up of metal` members We ded together, and more specifically consists of metal body holsters, adapted to'be carried on a truck or trucks, and a frame `work of metal'members supported` by the holsters, the members of the frame work being welded to each other and\to the ,body bolster', so that the whole `car frame is, an integral structure of great strength and rigidity and relatively small weight. Furthermore, the car frame is so designed as to provide suit able spaces foi-'the reception of storage batteries, and is adaptedt'o have secured to it the additional parts necessary to complete the car, such as Windows, platforms and hoods, and a roof.

The particular embodiment which I have chosen to illustrate my invention is disclosed in the accompanying drawings inwhich,

`Figure 1 is a perspective view of' a portion of my improved welded ear frame as seen from within, certain of fthe members beingshown broken or out olf; 2 is a plan View, partly \in section, `ort the frame structure taken onthe line 2 2 of Fig. 3; Fig. 3 is a vertical elevation, partly in section of the same taken onn the line 3-3 of Fig. and Fig.V 4 is a perspective view of the entire structure as seen' from without.

Snnilar reference numerals refer toy Similar parts throughout the drawings.

Referring to. thedrawngs, body holsters, preferably of cast steel and extending transversely o Each of the body holsters is provided with `openings therethrough, throughwhich extend A horizontally the longitudinal center sills 3 and 4; The center sills 3 and 4 are preferably of steel I shapes, and are welded tothe holsters at each intersection thereof. Each of the body holsters is provided with a vertical hole 5 at its middle to receive the truck bolt. Each body bolster isfshown prof vided with a' vertical web 6, an upper flange 7 ,a a lower flange 8, and vertical strengthening ribs 9although other strong and rigid forms of bolster may he employed.

Instead of using cast steel lbolsters as described, I may use steel shapes welded together to form the same shape construction as that described, or other suitable form.

To the ends of the center sills 3 and 4, and extending transversely thereof, are welded end sills 10 and 11. The end sills 1() and 1,1 are of steel channel. shapes, and are placed so that each has a verticalweb and two horizontal liangcs. Each center sillf is butted against and welded to the vertical web of an end sill, and the upper flange of each end sill rests upon and'is'welded to the upper surfaces of the ends of the center sills as is clearly shown in Figs. 1 and 3. The

^ end sills may be rounded at their lower cor- ;.ners as is shown at4 12. Extending longitudinally of the car frame are side sills 13 and 14. These sills are of steel channel shapes, and each has a vertical web and two horizontalI flanges and is placed so that the `channeled surface is disposed toward the interior of the car frame. The side sills The under structure of the transversely of the car frame and' having thlir ends welded to the side sills and center s1 s. sills may be used.y One flange of eachcross- Any suitable -number of these cross sill is horizontal, and 'the upper surfaces of Patented lDec. 23, 1913..v

' ends.

additional means of bracing*` the understructure, members 16, 17, 18 and v19 of steel angle shapes are provided. Each of these members extends obliquely between an end sill and the'adjacent body bolster, and one end isweided to an end sill near the junction of the center sill and the other en'd is welded to a body bolster near one of `its Cross sills 2O and 21 of steel angle shapes and similar to the'cross sills 15 eX- tend between the collision members and are welded to the collision members and also to the centerv sills. At each corner of the car frame gussets 22, 23, 24 and 25 are welded to the upper flanges of the end and side sills All of the parts out the understructure are preferably welded together by the Oxy-acetylene process.

The sides vof the car frame are formed of vertical posts 26 formed of steel angle shapes butt-welded to the upper flanges of the side sills 13 'and 14, and an outer sheathing of steel plates 27 and 28, there being one plate for each side. Each plate extends longitudinally the entire length of the car frame and vertically from the top of the vertical posts 26 to the bottom'edge of the side sill 13 or 14, and is Welded to the exterior surl face of one Hangs of each of the 'vertical posts 26, and to the exterior surface of the side sill 13 or 14. Longitudnally extending steel angle shapes 29 and 30 are Welded to the outside of theplate 27, and similar members 31 and 32 are welded tothe outside of the plate 28. These longitudinally extending members 29, 30 31 and 32serve to stiiien and strengthen the side structure. 'llhe welding of the plates to the vertical members, side sills, and longitudinally extending stiflening members is referably accomplishedelectrically an by the process known as spot Welding.` Longitudinally extending stiii'ening and strengthening members 33 and 34 of steel angle shapes are also Welded to the Vertical members 26 on the interior of the car trame. 'llhis Welding is also preferably done electrically.

ln assembling the structure heretofore described, the parts constituting a side, that is, a plate, vertical members, and longitudinal stifening members, may be `first welded together. T he side thus formed is placed in position with reference to a side sill', and welded thereto. The other side and side sill are assembled and united in a similar man. ner. The remaining parts may then be assembled and welded in place in the follow-` ing order: an end sill, the body holsters, the center sills, the other end sill, the collision members, the cross sills, and the gussets.

My improved car frame also includes two lattice girders, each girder resting on and meines welded to the` cross sills of the understruc- `ture and also `welded tov the side structure. p The chief function of these girders is to increase the rigidity of the bod In Fig. 1, only one of these lattice girders Ais shown the other being omitted to permit the understructure to be shown more clearly. Each v,lattice girder includes two members 35 and united by Vertical members 37, the members 37\`being welded at their'ends tothe members/ 35 and 36. Members 38 extend at right so angles to the vertical members 37 and the upper member 35- and are welded to the members 35 and .33. vMembers 39 extend from the lower member` 36 across the horizontal members 38-at an angle of about 45 tothe vertical members .37. The oblique members 39 are AWelded at one end. tothe lower member 36 at the junction of 36 and l37. AEach horizontalpmember 38 is welded to the corresponding member 39 where the two members cross each other, and oneof eachl pair of these members has metal forced out laterally .to contact with the other member as is shown at 40 in Fig. 2. rlFhe members 37, 38 and 39 are of steel angle shapes. 9 rlhe members constituting each lattice girder-may be Welded together electrically and the entire grder then putin place and welded by the Oxy-acetylene process to the understructure and sides. lVhen in lace the lower member36 of the lattice girder rests on and yis welded to the cross sills 15; the outer/ends of the horizontal members 38 rest on and are welded to the member 33 and Leach end butts against and is welded tov a vertical vmember 26 of the side structure; and each of the upper ends of the oblique members 39 is Welded to a vertical member 26. 0f each intersecting pair' of members 38 and 39, one bears on one side of a flange oit' a Vertical member 26 and tlie other bears on the other side of the same flange. This necessitates the forcing out of a portion of "one of each pair of members 38 and 39 as is Vot the understructure at the junctions of the side and end sills. Within the member 41, 43, 42, and forming with the Vertical portions 41 and 42 channel shaped posts, are steel angle shapes 44 and 45 welded to. the end sills at their lower ends, and also welded to angles 41 and 42 at their junction therewith.

` 'llhe upper ends of the members 44 and 45 130 are shaped to fit the curves of the member 41, 43, u42 and are welded thereto. Each bulkhead has also two vertical members 46 and 47 shown as hollow square osts. These members are also of steel an have their lower ends both -welded `to an end sill and their upper ends welded to the curved any gle 43.I The space. between 'these vertical members maybe utilized for the car doordescribed are preferably Oxy-acetylene weld-` ed. The plates 27 and 28 are welded, prefm4 erably by electrical spot welding, to the posts 41 and 42 at one end of the car frame and to the corresponding posts at the other end. The members 33 and 34 are welded to the posts '44 and 45 respectively and the member 3 5 to the member 49. The member 36 rests upon and is welded to the end sill 1l. The structure at each of the .four corners of the car frame is the same.

A steel plate 54 shaped as shown 1n Figs. 1 and 4 and vprovided with an opening 55 for a window or for ventilation, is spot weldp ed to the upper part of each bulkhead on the outside.- On the. outside of the steel plate 54 is welded a curved steel angle shape 54a conforming to the shape of and adapted' for the attachment of a platform hood. c

The center posts 56 and 57 and the arch 58 are formed. 1n a single piece of steel, chan- -nel shaped, and this` iece conforms in outline to the bulkhea s. This intermediate member takes .the place of two o f the vertical members 26 at the center gf the car, and rests upon and is welded at its ends to the side sills 13 and 14. The side plates 27 and v28 are spot welded to' the exteriors of the post portions 56 and 57 These ost portions 56 and 57 are also welded to t e members 33 and 34, yand each post portion is welded to a pair of intersecting members 38 and 39. If desired, additional intermediate members like the member ,56, 58, 57 may be used 4in a single car frame. Steel bands 59 and 60 extend along the upperportio'n of the car frame, and are spot welded to the exteriors of the posts 41, 56 and 41, and 42, 57 and 42 respectively. The steel bands 59 and 60 together with the bulkhead plates 54 form a; continuous metal band surrounding and connecting the upper portions of the' car frame.

frame are At the end of the car frame the space between the posts 41, 44 and'46- and below the cross piece 52 is covered by a steel plate 62 s ot welded to the members mentioned and a so to the end sill 11 and the cross piece 49- A similar late is provided at each of the corresponding portions of the car frame. These plates are perforated for a purpose hereinafter described.

The lattice girder is adapted to receive the car seats, and the space beneath the car seats may be utilized for the reception of storage batteries -tofurnish power and flight for-the car. The perforations in the plates 62 serve to ventilate the battery containing space. It is to be noted that the lentire structure when completed isy a unitary steel structure and combines a maximum of strength and rigidity with a minimum of weight.

The steel bands 59 and 60 have welded to them on the inside small steel angles 61 vertically nover the members 26. The steel angles together with the vertical members 26 are adapted to support the wooden window osts of the car.

Al of the members of my improved car referably rolled shapes of open hearth steel), except the body bolsters which are preferably steel castings. Obviously, the welding may be done by any suitable method.
