25 Claims.
This invention relates to improvements in mine and similar rail or industrial cars.
Mine cars are generally of either the rotary dump, end dump or drop bottom type and each type has previously been built with an end or sill construction peculiar to that type. The wide variance in types of ends necessarily resulted in higher costs and delays in construction, since each type of car needed a diiierent type of end 19 and it is an object of this invention to provide a simple cast end member that is suitable for use in either type of car. 7
Another object of the invention is the provision of a cast metal end member adapted to receive resilient bumping means.
A further object of the invention is the provision of a one-piece metal end member that is adapted for use in end dump mine cars.
A still further object of the invention is the Z0 provision of a one-piece metal end member of great strength having a large side sill contacting area.
These and other objects of the invention will be apparent to one skilled in the art after a study of the following description in conjunction with the accompanying drawings, in which Figure 1 is a central sectional view through a mine car having the improved end members attached and with the central portion of the car eliminated in order to more clearly show the end members;
Fig. 2 is a plan view of the mine car showing the end members and with the central portion of, the car broken away;
Fig. 3 is a front view of one-half of the member shown at the right side of Fig. 1;
Fig. 4 is a front view of one-half of the member shown at the left side of Fig. 1;
Fig. 5 is a sectional view taken through the spring of Fig. 6 and showing a modification oi the device of Fig. 1; and
Fig. 6 is a plan view of a little more than half of the modified end construction of Fig. 5.
Referring now, to the drawings in detail, it will be seen that the car, fragmentsof which are shown in Fig. 1, is built with end members A and B, each being formed in one piece and having extended contact with the side sills. The member A has provision for a wooden bufier block and the member B is so formed as to take a combined spring draft and buffing gear such as shown in Patent 2,012,114 granted August 20, 1935. It is obvious, of course, that under certain conditions both buffer members ,may be of the spring type or of the wood bumper type, but it has been found that an arrangement such as shown is very satisfactory and stands up well in service.
v The end member A is formed in one piece, preferably by casting, having a' substantially vertical web 2, substantially horizontal rear wardly directed flange 4, horizontal outwardly extending; upper and lower spaced apart flanges 6 and 8 respectively, and rearwardly inclined flange I0, all of which extend substantially continuous from;
side to side of the member. Gussets I2 of any desired number brace the flange 8 and web 2, and extensions it of these gussets connect and mutually brace the web 2, flange 4 andinclined flange l0, thus forming an extremely rigid-end member of large sectionmodulu's. The flange' l has widened portions "5 adjacent each gusset l4 and side wall, which portions are provided with holes E8 to receive rivets in order that the usual. belt or binder (not shown) may be attached if desired. I v
The top flange 6 and bottom flange 8 are provided with elongated slots 20 adapted to receive securing means, such as bolts, which will secure.
in position the wood block 22 and metal bumper The slots provide for longi- (not shown) adapted to be inserted in openings.
26 of the tongue and openings 28, 30 and 32 ex:
tending through the respective flanges and ,woodblock.
The flange I0 is inclined at the desired angle to give greatest bracing efiect and to. form a suitable chute for discharge of material if the car is of the end dump type. with openings 34 to receive rivets 36 securing the floor 38 in position. It is obvious that this flange.
may be extended and secured to the floor in the manner shown and to be described in connection with the member B at the other end of the car.
The ends of the web and flanges'are joined together by a side wall 48 which, in the instance shown, caps the end of the member and provides an extended area throughwhich rivets 42 or other suitable securing means may beinserted... The
side sills 4. are extended and have their ends coped to conform to the curvature of the flanges 6 and 8, while a flange 46 is extended outwardly from the side walls and is arranged to rest upon and be secured to the outwardly extending flange oi the side sill.
surface.
directed flange 56. The lower flange 52 extends The flange. is provided;
The rear portion of this flange is inclined as at 48 to present a smooth upper I The member B- is, like member A, formed in, 55 one piece with vertical web 50, horizontal lower; flange 52, portions of which are situated on bothsides of the web, upperflange 54 and rearwardly rearwardly beyond the web and has portions thereof enlarged as at 58 to take belt securing means as described in connection with member A. The flange has a fillet 60 which strengthens the connection of the flange and web at the points where the rearward flange extension is slight.
The rearwardly directed bracing flange 56 extends from substantially the horizontal center" of the web 58 and has a horizontal portion 62 and inclined portion 64 terminating in a horizontal portion 66 to which the floor may be secured by suitable means 68. It is, of course, obvious that the horizontal portion may be eliminated and the entire flange inclined, although with the form as shown a greater section modulus is secured. Bracing gussets'lfl of any desired number join the flange 56 to the Web 58 and these gussets as shown'extend both above and below' sheet. A horizontal flange 80 extends outwardly from the side wall and is arranged tobe secured to the side sill flange and also merge with an extension 82 of the web, which extension is provided for the reception of the end sheet (not shown).
The top and bottom flanges are provided with reenforcedelongated slots 84 for reception of the draft pin and with reenforced holes 86 for the reception of bumper securing bolts (not shown). The top and bottom flanges, vertical web 50 and side walls I2 form a pocket in which a combined spring draft gear and bumper is adapted to be inserted. It is'believed unnecessary to disclose this unit in position as 'it is fully shown and described in Patent 2,012,114 and by reference to this patent it is obvious that the' 90 has upper and lower outwardly directed horizontal flanges 92, 94 respectively, and rearwardly directed upper and lower'fianges 96, 98. The upper flange 96 has downwardly V and rearwardly inclined bracing or chute portion I80 terminating in' a' horizontal or other suitable portion I82 to which the floor may be secured by suitable means. The flange 98, as in the other forms, has portions thereof enlarged to provide portions I84 to which the belt or binder I86 may be secured.
Bracing gussets I08 connect incline I88, and flanges 96 and 98;to theweb in mutual bracing relationship directly behind spring centering projections I I formed on the outer face of the web. Spring pockets are 'formed by vertical ribs H2 and H4 joining the flanges 92 and 94 on either side of the centering projections and these ribs are extended slightly beyond the flanges in order to provide stops which limit the inward movement of the bumper later to be described, Each spring pocket is provided with an inspection opening I I6 through which dirt may also escape from rearwardly directed flanges.
2,101,169 V g the pocket. Elongated slots H8 are formed in the top and bottom flanges immediately adjacent the spring pockets, which slots are suitably reenforced by ribs or beads. These slots provide for movement of bumper securing bolts I26 which hold the U-shaped bumper E in position.
The bumper is of somewhat usual form, having a curved face with portions thereof inset to pro vide stiffness as well as to form the spring seats. The bumper plate is provided with slots I22 through which the coupler pin may extend, thus permitting inward movement of the bumper against the resistance of springs S.
The ends of the various flanges, web and in-- clined portion previously described are joined by the side wall I 24, which is of a length equal to the width of the end member, and thus provides a large securing area by which the end member is fastened to the side sills I26 by means I28. A projection I30 of the wall above the incline may be used if this addedsecuring area is necessary. The side sills, which as shown are of Z-form, have the inwardly directed flanges I32 secured to the flanges 94and 98 to give additional stiffness and support, and these sills are extended to the outer edge of the end member in order that the entire end membermay lie between the sills, thus giving a large sill securing area. A suitable coupler tongue I34 of T or other'cross section is provided andis formed with a hole I36 to'receive the usual coupler pin which extends also through suitable holes in the flanges 92'and 94.
It is obviousfrorn the description of these various one-piece end members that an extremely simple and rugged end member has been provided which'is suitable for end dump cars in which case the bracing incline acts as a chute to carry the lading out of the car, and this same member when used in rotary dump cars provides a smooth corner which will prevent retention of lading in the corners. These end constructions also lend themselves readily to drop bottom cars, since the door hinge rod may be inserted through the structure below the incline which then acts as a guard for the door hinge.
Although the'device has been shown and described in more or less detail, it is obvious that various modifications thereof may in the future be necessary or desirable and that these modifications may be made without departing from the scope of the invention as defined by the appended claims.
