DUIVIPING-CAR.
SPECIFICATION forming part of Letters Patent' No. 461,607, dated October 20, 1891.
Application led May 20, 1891. Serial No. 393 ,412. (No model.)
To all whom t 11i/ay concern:
Be it known that I, GEORGE GIBBS, of Milwaukee, county of Milwaukee, and State of Improvement in Dumping-Cars, of which the following is a specification.
This invention relates to that class ot' cars for transporting ore and similar materials which are constructed to discharge or dump the contents through the bottom. Many ores, particularly iron ores, when first mined contain a large percentage of moisture, so that when loaded in this condition into cars in cold climates the entire contents become frozen and solidified into a solid mass, which it is impossible to discharge from cars ot' ordinary construction except at great expense and by destructive processes, it being necessary to break up the mass and frequently to employ blasting-powder, with, of course, destructive effects upon the car.
The aim of this invention is more particularlyvto provide a strong and simple car of such construction that the entire contents may be readily dischargedwvithout the necessity of breakingr it up. To this end I construct the body of the car and its dischargeopenings in such manner that the entire mass may escape without change of form, and in order to free the mass that it may thus escape I provide a false bottom through which steam may be circulated to loosen the hold of the material upon the car.
In the accompanying drawings, Figure 1 represents a side elevation of my improved car. Fig. 2 is a longitudinal Vertical section of the same on the line 2 2 of Figs. 3, 4, and 5. Fig. 3 is a plan View of the frame-Work. Fig. 4t is an end elevation of the car-body. Fig. 5 is a transverse section on the line 5 5 of Figs. l, 2, and 3. Figs. 6 and 7 are detail views of the false bottom.
My car is constructed with a body having atopposite ends two V-shaped hoppers, the inner or adjacent walls of which are formed by doors, each hinged to swing downward toward and beyond the middle of the car. In
constructing the car the first essential requisite is to build the frame in such manner that, being supported as usual, it will possess the necessary strength to carry the load, and
at the same tinievleave an open entirely unobstructed space between the trucks' and across the entire width of the car, so that the doors or hopper-bottoms maybe opened to the required extent,'aud that sufficient space may be left between the trucks to admit of the entire load of the hopper passing downward therethrough without change of form.
lVhile I have represented in the drawings those details of the frame-work which I prefer to use in practice, it is to be understood that the framing may be modified at will, provided only it retains the characteristics above named.
Referring to the drawings, A represents a rigid frame-work of oblong rectangular form resting at its opposite ends upon the swiveledwheeled trucks B B in the usual manner.
C C represent the two V-shaped hoppers to receive the ore located in opposite ends of the frame. The sides of these hoppers are formed by vertical side walls c c, fixed rigidly to the car-frame. Each hopper has its bottomformed of a rigid inclined wall c', fastened to the carframe near the end of the frame, and an inner inclined door c2, supported at its upper end by a hinge c3 from across bar or beam c4, fixed rigidly across the top of the frame midway of its length, the edge ot this swinging door being held in a closed position by means of hooks or latches c5 engaging its loweredge. It will be observed that the space between the hinged hopper bottoms or doors cf2 is entirely open and unobstructed, so that when either A door is released at its lower end it may swing not only downward, but also upward until it encounters the door at the opposite end, as shown by dotted lines in Fig. 2, thus entirely releasing the mass in the hopper and aording for its delivery a passage of increasing area in the direction of discharge, so that, although the contents of the hopper may be a rigid unyielding mass or block, it can pass down freely out of the hopper and through the central opening in the frame. There are several latches c5 for each door, all mounted on a rock-shaft c, controlled by an arm c7 and an upright rod c3, having a locking shoulder o9, engaged under a bearing on the frame,
where it is held by a wedge C10, or equivalent' device, to prevent the parts from being accidentally unlocked.
IOOk
It will be observedV that in my car the contents of one hopper is discharged in a path which intersects the path of discharge from the other, so that the load can be delivered from only one end at a time.
I believe myself to be the Iirst to construct a dump-car in such manner' that Athe hopper door or bottom may swing downward and backward so far as to afford an outletpassage of increasing size that the entire contents of the hopper may be delivered without change of form, and I also believe myself to be the first to construct a ear with a central unobstructed opening through the frame of suc-h character as to permit the passage of the entire load therethrough in a solid mass.
I recommend that the framework be` conestl'ueted as represented in the drawings, in which a d represent thev longitud inal side walils; a2 d2, the short draft-sills; a3 a3, the cross-siflils at the ends; d4, the diagonal braces for stiffening the frame; a5, the longitudinal side timbers forming the top of the frame, and a6 (L7 the posts or braces sustaining said timbers from the sills. The entire frame-work may be tied together and strengthened by truss-rods, as shown, or in any other suitable manner;
In order to overcome the adhesion of the ore to the car when frozen thereto, I pro-pose to provide the hoppers at the bottom andalsoi tthe unobstructed central discharge-opening through its bottom, in combination with the central cross-beam at the topl and the two gdoorsh-inged to said beam and form-ing the at the sides, if desired, with a false bottom or jacket of any suitable construction. The preferred construction of this bottom is; represented in Figs. 2, 6, and' 7, in which F represents a corrugated metal plate riveted to an underlying fiat plate f, the two being seated and secured against the hopper bottom. A steam-pipefcommunieates through a transverse passage f 2 with the interior passages between the metal' sheets, thus al'low- 1 4' myv hand, this 18th day of April, 18911, in the ing steam to be introduced to. heat the entire` surface of the load. A drainage-pipe]c3 is provided for the discharge of the water of condensation at the lower edge.
Having thus described my invention, what I claim isl. In a dumping-car, a frame having an unobstructed discharge-openin g between the trucks, in combination with two hoppers located at opposite ends of said opening, their inner walls formed by doors hinged at the top and each adapted to swing downward and backward iu such manner as to permit the delivery of the entire contents of each hopper without change of form, whereby a mass of frozen ore or other solid material may be delivered without being broken up.Y
M` 2. In a dumping-car, the combination of a frame having a bottom discharge-opening therethrough, a hopper having one of its inclined walls fixed in position and its entire opposite Wall hinged to swing downward and backward to or beyond a plane parallel with that of the stationary wallrwhereb-y a frozen or other solid load may be delivered bodilyl from the hopper.
3. In a dumping-car, the frame provided with sustaining-trucks at its ends andwith .the wholly unobstructed' opening betweenl saidi trucks, in combinationl with the fixed incl'ined walls formiingthe outer sides of the hoppers,` and the two d'oors hinged at their upper endsand forming'the entire inner Walls of the hoppers, each of said doors adapted to` swing downward and backward iin-to the path 7 of the other;
In a dumping-car` the frame having bottoms of the respective hoppers.
5. In a dumping-car, arfalse bottom or lin ingapplied to the: inner surface of itshopper` 1 or receptacle and adapted for the passage ot" steam or other heating fluid therethrough.
In: testimony whereof I'have hereunto set presence of two attesting witnesses.
