i inay include conventional side chassis beams or reinforcing relation therewith and is riveted sills B and C, to which afloor D may be secured thereto in a `manner to `be subsernienmyV de- 50 in` any approved relation, and at Athe ends of` scribed. The top edge42 of the Wall il iits u which end sill `or bumper `structures E may be against-the under surface of the iiangejan l secured, at both ends `of the mine car, in accordat its lowermargin the-Wall`4l is provided Witli ancewith usual construction. i i i the horizontal flange 43, which maybe referred `The vside sills `are of usual {channel-shaped to as the lower flange, and which is bent normal iormatiomivith the channelgfroves Vfacinglout to "the wall or plate 41;" Thecorners or theV110 flange 43 are removed, so that the flange 43 in accordance with usual construction tapers from the sides thereof convergently towards the free edge 44 thereof, which is preferably arcuated conveXly. The upright wall 41 is not quite as high as the wall 27 of the member 26, so that the supporting flange 431s disposed in a plane slightly above the lower marginal portion of the wall 27, as is shown in Figure 1.

A second metal angle member 4S is provided, which has an upright wall or web 47 of the saine length or substantially the same length as the walls 27 and 4l of the members 28 and 49 respectively, and which is adapted to lie at the outer surface of the wall 41, immediately beneath the flange of the supporting member 26, as shown in Figure 1 of the drawings. The height of the wall 47 is considerably less than the height of the wall 41. The angle member includes also a horizontal supporting and attaching flange 48, which may be referred to as the upper flange, sinceit is spaced above the flange 43 of the member 40. In assemblage the edge 50 of the angle member 48v is dispose-:l flush with the top edge 42 of the wall or web 41 of the member 40, as shown in Figure 1 of the drawings, with the reinforcing uprights or plates 41 and 47 in abutment with each other, and in relation to the wall 27 above described, and as shown in Figure 1 of the drawings. At opposite sides of the medial portion of 'the wall 27 and the reinforcing uprights 41 and 47, there are provided on the walls or uprigts 27, 41 and 47 respectively a series of openings 52, 53 and 54, which align to receive rivets 55, by means of which to rivet the plate or wall parts 27, 41 and 47 in abutting relatively reinforcing relation, asshown in the drawings. This spaces the horizontal lower and upper flanges 43 and 48 in spaced parallel relation, and said flanges are similarly formed at their marginal portions, so that the peripheral end edges thereof lie in the same vertical planes. Between said horizontal flanges is provided a space within which a wood illler piece 59 is disposed.'

The angle clip-like draw bar 23 includesy the attaching flange or leg 80, having openings 61 therethrough, adapted to align with openings 63, 64 and 65 in the walls or upright plates 27, 41 and 47 respectively, for receiving rivets 68, as shown in the drawings. .The draw bar clip 23 also includes the horizontal draw bar body or flange 68 which extends horizontally forward above and in contact with `the attaching flange 35 of the end sill member 26, and which draw bar body is provided with openings 70 therein adapted to align with opening 71 in the outer marginal portion of the flange 35, and thru which openings rivets 25ZL are extended to secure the draw bar body 68 in a reinforced braced relation as close to the outer end of the draw bar body as convenient. The outer portion of the draw bar ilange or body 68 is provided with a coupling pin inserting opening 72, through which the coupling pin 73 is adapted to be detachably inserted, so that the head 74 of said coupling pin rests on top of the draw bar body 68, in accordance with usual construction. The recess 22 is cut in the mine car floor D in order to' accommodate the draw bar body 68 in the relation of structure above described, and as is shown in Figures 1 and 2 of the drawings,

The upper and lower flanges 48 and 43 respectively, receive the fiat filler block 59 therebetween in substantially a conforming relation. The rear surface 75 of the illler block 59 abuts against the front surface of the lower portion of the reinforcing wall 4l, as shown in Figure l, and in this position the outer marginal portions of the filler kblock project beyond the outer edges of the said flanges 43 and 48, as shown in Figures 1 and 2 of the drawings, so that the abutting forces will be taken up in the ller block 59, which is preferably of wood, although it may be of other material, and more yieldable than the other metal parts of the composite bumper or end sill structure. rihe flanges 43 and 48 are respectively provided with openings 78 and 79, in their outer ends, along the medial line thereof, through which the coupling pin 73 extends, as shown in Figure 1 of the drawings. The filler block 59 is provided with an opening 80 therethrough, which is elongated along the axis of the mine car, and thru which the coupling pin shank also extends. The filler piece 59 engages at its upper and lower surfaces in sliding contact with the faces of the flanges 43 and 48.

A channel-shaped metal bumper piece 82, best shown in detail in Figure 10, is provided, including upper and lower horizontal flanges 83 and 84, and a bight portion 85 which is concaveconvexly arcuated in the plane of the flanges 83 and 84. The channel piece is straddled above and below the ilanges 43 and 48, in the relation shown in Figure 1, with the inside surface of the arcuated bight or connecting portion 85 abutting against the forward projecting part of the filler block 59, as shown in Figures 1 and 2 of the drawings. The flanges 83 and 84 are provided with elongated openings 87 therein, adjacent the free ends of the flanges, through which bolts 88 are disposed; the bolts 88 being detachably connected through suitable openings 89 and 90 in the flanges 43 and 48 respectively, and two elongated openings 91 in the illler block 59, as is shown in the details of these parts in Figures 6, 7, and 8 of the drawings. The flanges 83 and 84 of the channelshaped metal bumper U2 are each provided with elongated openings 93, adapted to align with the openings 78, 79 and 80 above described, to receive the shank of the detachable coupling pin, in the relation shown in Figure 1 o1" the drawings.

It is quite apparent that shock occasioned by the bumping of the end sill structure, at the bumper member 82 will be transmitted to the rather yieldable filler block 59, without placing a strain or shearing eiect upon the coupling pin 73; it being understood that the bumper channel 82 may move relative to the upper and lower be supported in a protected relation inwardly out of obstructing relation with the bumping parts of the end sill, as shown in Figure 2, by providing a substantially U-shaped retaining bolt 97, slidably supported at the body portion 98 thereof in a series of aligned openings 99 provided through the three thicknesses of the plates 27, 41 and 47; the bolt 97 at the inner side of the end sill below the mine car bottom having a retaining extension 100 transverse thereto, and forwardly of the reinforcing Wall 47 being provided with a normally downturned latch extension 101 provided with an enlargement 102 on the lower end thereof. By gravity the bolt 97 assumes an inverted U-shaped position, with the head 102 of the extension 101 spaced above the horizontal upper flange 48 for arenas-@1o e distance less than the thickness ofthe end uns oithe chain 95, s0 that, as shown in Figures and of thedrawings, the chain when inoperative may belinked over this extension 101` and retained inlanyout of the Way position upon thefendsill. Of course,1to detach the chain from the Ul-shaped retaining bolt 97,;it is merely necessary to turn thetsame sidewisefand release the endflinktherefromin a `rrlannerwhich is obvious.

`In the4 provision of the above `described type ofnsbumper or `end sill for `minefcars, there are several` important `features which. differ tit `from conventional minecar end sill construction. l It is well known, that underpracticalfconditions of usethe `end `sills of mine cars bow outwardly, dueto ,theheavy load whichmust be pulled thereby,` and ,the continual jerking which they receive during haulage through the mines. rIVhis is true of fevenf ,the most modern types of minecars. However, with the improved `mine car end sill described, I have found, that under practical conditions `of use, the sillis longitudinally reinforced to effectively withstandtransverse bending, by reasonotthe transverseparallel connection of the walls ortplates 27, 4l, and 46. As another improved "feature, in conventional niinecar end sills orbumpersethere isa space` provided on the end sill; between upper and lower angesfor receiving the chain links of the coupling chain; Very oftenthe upper iiange becomes bent Aout of position, and `destroys the eiliciency` ofthe entire end sill. Furthermore, there are many times when it isdangerousfor a person to couple mine cars together, as `the operators hand is `liable i tobecomecrushed between" the ordinary topplate andthe.,ller piece, either directly, or byreason of .fthelinks squeezing Vthe operators hand. In other words, `thelinks do not have suicient clearance sin conventional construction, but `in the improvediformof invention herein setNforth, the Ylinks occupy 1an "unobstructed relation laterally ofwthe draw `bar body and have no` overhanging `by `letter `F, the` supportingA membei1 26a Vis not provided with a top attaching `flange, but the plate portionY 27a thereof forming the `transverse wall betweenthe `side sill, is provided'with,anotch or recess 28?" inwardly from` the top edge 29e thereorijv'vhichf,receives the drawfbar bodyY 63,a at its "juncture with the rear attaching leg or flange 60, as shown in Figure 11.

It is also to be noted, from, Figures 13.land"14,fthat the reinforcing plates or walls a7a and 41a, which correspond to the walls 47 and 41 of themembers 46 and 40 of the .preferred Yform of invention respectively, are notched inwardly of the top edges thereofoat 48b o 3 and `48` respectively, to accommodate the longitudinally extending drawibart'body 68a inthe position shown in Figure 11.
