Application .filed May 8, 1924. Serial No. 711,885.
My improvement relates particularly to mine cars which are to be turned or tilted bodily forward for the discharge of their contents.
The main object of my invention is to produce a mine car which is adapted to be turned or tilted forward for the discharge of its contents, as above stated, and which has its floor or bottom low relative to the track, in order that for a given head room the car will hold a maximum load, and, for the sake of greater stability of the car on the track, carry the load close to the track rails.
To this end, the car comprises a main frame composed of end sills and parallel side sills, a bottom or floor section between said side sills, an auxiliary floor section outside of said frame, axles supported by said side sills, wheels on said axles, and slanting housings for the wheels.
In the accompanying drawings,
Fig. 1 is an elevation of a mine car embodying my improvement, the bottom of the car being especially constructed for tilting the car endwise for dumping its load, portions being broken away;
Fig. 2 is a plan of the car shown by Fig. 1, portions being broken away;
Fig. 3 is an upright, longitudinal'section on the line, 33, of Fig. 2;
Fig. 4 is an upright, transverse section on the line, 4-4, of Figs. 1 and 3, looking toward the right;
Fig. 5 is anupright, transverse section on the line, 5+5, of Figs. 1 and 3, looking toward the rig Fig. 6 is an upright, transverse section on the line, 66, of Figs. 1 and'3, looking toward the left.
As above stated, the form of car shown by the drawings is intended to be tilted forward in a tipple which rotates on an axial line which is transverse to the length of the track. In said drawings, A, A, represent end sills having abumper, A projecting outward therefrom, a draw bar element. A also pro-' jecting outward from said'end sills and located over said bumper, truss members, A
and corner stiifeners, A and A all prefer ably formed of one integral casting.
The said bumper, A isv swelled outward as indicated by the drawing, and immediately over the central portion of the bumper is the aforesaid draw bar element, A provided with a coupling pin opening, A, which is directly over a similar opening, A, in the bumper, a space being left between the draw wise thrust and also train pull. Atthe same time, the frame consisting of the side sills and the end sills must possess sufficientflexi bility to allow the axles to incline independently ofeach other, whereby the car wheels atthe same side of the car are allowed to assumedifierent levels to conform to variations or irregularities in level of the track on which the carruns.
The two, axles, C, arearranged transversely tothe side sills and rest in bearings, C secured to the side sills by bolts, C In the form shownin the drawings, saidbearings are applied flatwiseto the outer sides of the side sills and extendthrough the sills.
On each end of the axle is a track wheel, W. This arrangement brings the axles above the level of the lower edges of the side sills.
Abott-om plate, E, is placed between the side sills, at the left hand end of the car and I extends from one side sill to the other from the rear end sill forward at the level of the.
lower edges .ofthe side sills to a line approxi mately midway between said end sill and the rear axle. C. Thence said plate extends forward and obliquely upward to or nearly to the rear axle. Along each side edge, said plate has an upward-directed flange, E, which bears against the adjacent side rails and is secured thereto by bolts.
-The middle floor plate, F,.extends below and rearward of the rear axle, C, and along the lower edge of the side sills to a point between the two axles, and then said plate extends obliquely upward and forward to or nearly to, the upper face of the forward axle,-
At' each side edge, the plate, F, has an u ward-directed flan e F which bears against the adjacent-inner face of the side sill and is'secured to said sill by bolts or rivets. Along its rear edge rearward of the rear axle, said plate has an upward-directed flange, F which rises to or nearly to the bottom plate, E.
bolts: or rivets. Along its rear edge and rearward of the forward axle, said. plate has an upward-directed flange, G rising to or nearly to the plate, F. a I
A movable door, not shown, is to be placed above the forward end sill. Said door is to be opened when the car is to be tilted forward for the discharge of the load It is to be understood that the slant of .the inclined bottom sections relative to the horizontal'plane of the car is to be such as to. allow all the coal to slide from the car when the car is tilted forward on the tipple,
, In this" connection we must take into consideration the slant at which the car is placed by the tipple.
There are lateral horizontal extensions of the bottom. To the outerfaces of the side sills, B, are applied the upright arms of brackets, H, by means'of bolts orrivets, H
Said brackets constitute supporting members. The other arms of said brackets extendhorizontally away from the sills. Bot- 7 tom plates, H rest, on said arms of the brackets and extend from the side sills outward to the outer limits of the car body. Said plates are secured to said brackets by bolts or rivets, H
At each of the fourwheels, there is as opening inthe adjacent bottom plate, H
to make room for the upper part of the wheel, that part of the wheel extending above the plane of said bottom plates. At
7 each wheel, a metal housing, H extends over the wheel and has base flanges, H
which rest on and are riveted to the adjacent bottom plate. The rear part of each housing is extended rearward to incline or slant its upper face to allow coal or other material to slide forward over thehousing when the car is tilted forward for the forward discharge of its load. Thus the for-- ward part may be concentric to the wheel, while the rear part of the housing is given the slant or incline above mentioned.
Upright side walls, I, have flanges, I resting on and riveted or bolted to the ad'- jacent bottom plate. The rear end of the car has a fixed end wall, I At the forward end of the car the door is to be regarded as an end wall. While it is closed, it serves as such. While the drawings show the auxiliary bottom plates, H at the-elevation of the up- I per edges of the side sills, it is to be noted that the horizontal arms of the brackets, H, may be placed lower for correspondingly lowering these bottom plates. In some situations, placing these side plates lower than is shown in the drawings would make their outer margins'liable to contact with objects lying beside the track. Where the track can be kept clear in this respect, the bottom plates may be placed lower than shown.
Attention is again asked to the desirability of placing a load close to the track rails, in order that the car may be adapted to carry a maximum load where there is low head room and in order that the car may have greater stability on the track.
Placing the bottom plates low between the side sills, as herein described, and placing the horizontal auxiliary bottom plates, H
outside the side sills will place the load as close to the track rails as operatingflcondh tions permit.
The manner of applying the bottom plates, H affords ample stability for those plates and for the wheel housings, H
I claim as my 'nventionz 1. In a car of the kind described, the com bination of a frame comprising end sills and side sills, axles applied to the side sills above the lower edges of said sills, a stationary bottom structure extending below the top of the axles and from one side s'll to the other, supporting members extending out ward from the side sills, auxiliary bot-tom sections resting on said supporting members and having wheel openings, housings seated over said openings and slanting rearward to permit forward sliding of coal when the car walls, substantially as described. 2. Ina car of the kind described, the combination of a frame comprising end sills and side sills, axles applied to the side s lls, a bottom between the side sills, an auxiliary is tilted forward for discharge, and upright bottom section at each side of the frame, wheels surrounding the axles and extending upward'through openings in the auxiliary bottom sections, housings seated over sa d openings-and slanting rearward 'to permit forward sliding of coalwhen the car is tilted forward, and walls rising from the auxiliary bottom sections, substantially as described.
In testimony whereof I-have signed my name, this 6th day of May, in the year one thousand nine" hundred and twenty-four.
HUGH W. SANFORD.
