ed between the tracks, in the usual slightly off center position, by the other parts referred to, as shown in Figs. 1, 2 and 3. This reduced number of parts materially simplifies the process and labor of erection.

The'term bumper head, without more, is used throughout the specification and claims in a broad sense to indicate generally, andregardless of theparticular construction, those parts of the post to which the stress of impact is delivered. In the structure illustrated, however, the details of which are now to be described but without limitation thereto except where included in particular claims, instead of the customary heavy casting, the bumper head is a light, but strong, box-structure fabricated by welding together rolled plate-steel members as best shown in Figs. 13, 14 and 15. In these figures 1 indicates the bumper face plate, 2 and'3 side plates both cornering on the back of the bumper face plate 1 at the outer front edge of each and welded thereto, 4 and 5 inner top and bottom end abutment plates cornering on the back of the face plate at the lower front edge of each and welded theretobetween the side plates, said plates extending downward and rearward in parallel planes, 6 a vertical brace and spacer plate having its front edge in the plane of the rear of the face plate and welded thereto and its top and bottom edges re spectively in the planes of the platesf l and 5 and welded thereto, and 7 and 8 top and bottom cover platesoornering on and welded to the rear of the face plate at the lower front edge of each and welded to both of the side plates. The plates 7 and v8 may extendbeyond the side plates and both are provided with bolt holes 9 each aligned axially with one of the bolt holes in the other plate. The top cover plate 7may have a groovelO in each side edge for the reception of a tension member, as will be hereinafter explained. All the plates are brace plates, since they strengthen and brace the structure.

The shape and relation of the various plate members or plate pieces will be apparent from the drawings and particularly from Figs. 13. 14 and 15. They are square-sheared and welded incornerwise relation to the back of the face plate which avoids the necessity of finishing their front edges on an angle or bevelling to fit the face plate and makes it possible to readily weld them at any desired angle. Welding fills in' the crevice, thus producing ample bearing andattachment of one section to the other. This arrangement not r 1 1ly promotes strength and lightness but makes it possible to vary the shape of the head at will to suit particular compression members or other special conditions. The readiness of adaptability thus obtained is in dicated by the modified construction of the.

head shown in Figs. 17, 18 and 19, wherein the headshown in the other figures which is adapted to freight cars, is extended forward to give additional clearance to the air hose and steam connections as used in passenger cars and is provided with means for returning the coupler bar to center, which is desirable, since the ends of passenger cars, as is well-known, have a much longer swing than the ends of freight cars. In the three figures referred to, spacer, brace plates 11, shown as identical horizontal plates, with curved front edges, equally spaced vertically are welded to the front of the face plate 1 and to the rear of the horizontally concave strikerplate 12. Side cover plates 13, 14: may be welded to the front of the face plate 1, the rear'of the plate 12, and to the adjacent ends of the space plates. The various plates used in the bumper head and its extension may be of any appropriate thickness, but I have found that face plates of 1 4 thick ness and other plates thick serve the purose. p The bumper head as thus formed provides a box opening downward at the rear and of suitable dimensions to receive the upper front ends of both the compression members 15 whichare preferably H beams, since beams of this cross section are much stiffer than channels or members of other cross section. As indicated in Fig. 13, the forward ends of the H-beams 15 abut respectively on the adjacent rear edges of the plates 4:, 5. The flanges of the H-beams are in contact at the top with the underside of the cover plate 7 and at the bottom with the upper side of the cover plate 8; their outer edges are in contact with the inner sides of the side plates 2, 3 andthe inner front corners of the flanges of the left hand H-beam are in contact with the inner edges of the right hand H-beam, so that the said ends of the H-beams occupy the said space in the bumper head across the head and the parts are maintained in right relation and the structure well braced. Separate housing'of the ends of the H-beams is unnecessary, the arrangement described being preferred. .While H-beams are for-reasons stated particularly desirable as compression members, they do not readily lend themselves to such use owing to the difficulty of associating them in proper thrust contact with the bumper head and particularly with the rails and road bed. The way in which their relation to the bumper head has been taken care of has just been described, the other part of the problem has been solved in the manner now to be stated.

Referring particularly to Figs. 9 to 12, the compression track fixtures which are substantially the same but reversed are built up out of plate or plate-like elements, as indicated in Fig. 9, which illustrates the left hand compression fixture showing separated the'ele- Inents considered most desirable along with the end of the adjacent H-beam, which is i0 y y a i inclined to suit/the incline ofthe topof the CEBU of the r'ail and the flange 21secure the comto be 'vveldedntothetrack fixture to form a composite compression unit. In the illus-l tratedembodimentof the intention; these elements aretheipartsnumbered 16; 17 and 18 and they andthe H -beam are Welded toe gether in anyyx-convenie nt order. or these elements, 16is the rail engaging plate, which has a base 19 adapted to seat on thefiange at the inside ofthe rail preferably by pads 20 welded thereto and having their bottoms rail flange, anduan upright rail attachment flange 21 having bolt holes 22 and preferably havingsspacer pads 23 Welded thereto and through which said holes extend. Part 17, an angle h'avingiend abutment 24: 'andleg 25, is-=securedwto the plate 16, preferably by Welding its side edge "26 itothe. inside face of the upright flange 21 and having its lowerrear edge 26 cornering oniand welded tothe base 19. The abutments 24am supported sufficientlyinward of the rail to avoid need of no any mitering or specialfitting oftlie H- beam in order to produce a proper bearing of theone upon the other; square-sawed H- beams are thus madeavailable; The upstanding brace platel8 Whichmayserve also as a tiered-anchoring plate is Welded both to the hjase 19:1and to both legs of the angle 17 into whichfiit fits.

It is convenientto speak of the compression track fixtures? as if they were distinct from the compression members, but, in the structure illustrated; they are actually extensions of the respective compression members being 111 tegral'therewith in the finished structure.

The'tension members areshown asbai's 33 one end, means for fastening the barto the headandat the other, means for fastening the barto the road bed, such means being in the nature of integral side extensions as will appear in the detailed description, in

Whicln for convenience, they are designated" by separatenmnes, As shownwin F igs. 3, 13 15 and 16, the upper end of each bar 33 passes. through a hole 33a in an off-settingblock 34 to Whose faces the Walls of the hole are normal and to ivhich the bar is Welded. The block 3%, when the post is assembled, seats on top of the cover plate 7 which lies in aplaneinclined to the vertical and to the horizontal, and the blockextends inwardly ofcircular section having Welded thereto, at y andrearward;andthe bar outward and for- Ward. ."lheaXes of'the bar and hole are thus augularly related, aslndicated in Fig. 16, and the bar 33 touches only the inner slde of the top edgerot the hole and the outer side of i the bottom edge ofthe hole leaving space in the hole for the fused steel or Welding material above the bar toyyard the outer anddielovv the bantowardthe"inner side. This makes an exceptionally secure attachment; 1 Each otthese blocks is also l'n'ovidedj i the head. I

lThe preferred tension connection to the; road-bed substantlally dupl cated in reverse, ad acent each rallyis shown in 1 to 6 inclusive, wherein each tension bar 33 is shotvnas passing through hole 335 in the horizontal plate port1on 37 of the tension track fixture adjacent the upturned rail at tachment flange38 and welded to the track fixture at both sides of it.

lie

the angle ofthe bar and the resulting erevices arefilled in with fused steel in the Welding of theparts together. The bar is thus welded onbothfaces of theplate. The tensionstructiue is designed to transmit the strainto a heavy cross bean139, extending between the tles across the track andseatrng under the respective rails as in my pending application, Ser. No. 390,417, filed September 5, 1929, wherein specifically different structure having common characteristics is shown and broadly claimed. The plate 37 has welded thereto a spacer pad 40, which seats on the top of the cross beam 39, thus locating the plate 37 in a horizontal plane. In the construction illustrated in the. said figures, the tension structure includes means for receiving and surrounding the cross beam. This is a U-bolt 41 whose closed end having weldedtherein a filler half disc 42 seats on the underside of the cross beam, the bolt being provided with nuts 43 and having its legs at the ends of the spacer pad 40. The railattachment flange 38 of the tension track fixture has welded thereto pads 44 which seat 011 the inside of the rail web. Said flange, pads and web are drilled to provide holes for attaching bolts 45, which pass also through correspondingly located bolt holes in clamp bars46, similar to the clamp bar shown in Fig. .9 but shorter and having only two bolt holes and are secured by nuts 47. Lugs 48 welded to the top flange of the cross beam 39 near 'each end of the beam serve as abutments for the inner edge of the respective plates 37 to prevent the plates from being drawn toward each other on bumper impact. It will be apparent that the composite tension and track fixture memberas well as the composite compression and track fixture member can be handled as a unit. The tension track fixtures are located directly opposite to each other in the track and serveto correctly locate and anchor the tension cross beam and to transmit'stress of bumper impact thereto and also to the respective rails to which the plate members 37 are attached. The tension bars are welded to the track fixture plate at a point between that at which the tension structure embraces the cross beam (U-bolt) and that at which the tension struc ture is secured to the rail (bolts 45), so that the pull of the tension member distributes part direct to the rail web and part to the beam 39 and rail base.

A slight modification of'the tension con nection to the rail and road bed is illustrated in F 7, which represents this connection applied to a girder trestle, such as is used for coal pockets and wherein an I-beam 49 underlies each rail. Here, also, the tension bar 33 passes through and is welded to the base plate 37 of the tension track fixture, which has the pad 40 and the rail attachment flange 38 and is secured to the rail web in the manner described in connection with Figs. 1 to 6. It will be observed, however, that plate 37 is extended further inward toward the center of the track to clear the flange'of the I-beam and that the lug 5O welded to the top of the cross beam 39 is extended under the adjacent flange of the I-beam and has its upper. surface inclined to correspond with. the under surface of the I-beam flange. It will be seen also that the lug 50 extends further above the upper side of the cross beam 39, as itmust, in order to oppose the inner edge of the plate 37. The U-bolt is also necessarily longer and is located just beyond'the pad 40.

Another modification of the tension connection to the track is shown in Fig. 8, wherein the closed end of the U constituted by the U-bolt is omitted and upright bars'or legs 51 are welded to the front and back of the cross beam 39, filler blocks 52 of substantial width being welded to the respective channels and to said legs. The rest of the structure is as above described in connection with the form illustrated by Figs. 1 to 6.- No attempt has been made to exhaust the possibilities in designing modified forms of the tension connection, and it is to be understood that, except as may be specified in particular claims, the invention is not limited to the details shown. The modified construction illustrated in Fig. 8 has the advantage of requiring less excavation and it or some other arrangement, preferably of welded parts, which does not extend below the bottom of 'the tension cross beam but which secures it with requisite strength to the rest of the tension structure may be employed. --Tl1is post without alteration fits any rail from 5 to 7 high. -By modifying it slightly, it can be constructed to suit lower or higher rails. The parts are so light and so readily handled that the simple operations incident to setting up the post can all be performed by one man.
