B ltl known that I, .PATRICK J. HARRIoAn,
-a"'c it i fzf en {of the llnited States of America, residing at MoKeesport, in the county of,
Allegheny and State of Pennsylvania, have .iiivented" certainQnew and useful Improvements in Dump Cars and Vehicles, of which thefollow ng is a specification, reference betherein td the accompanying draws ,This,,inyentionrelates to dumping cars,
and ;more;, particularly to that type o-f car,
" comm ohlystyled af'hopper car,and used f ra ransporting coal,- coke, iron ore, and h r ar rial-of high and low specific gravity-o s i mas o jecto fthe invention broadly stated is to provide a hopper car which can be advantageously employed for thehaulingof materials of; high specific gravity, such as iron ore, ore scale, .flnedust, etc, and also util zed forrthe hauling of material of lower spec fic grav1ty,- such as coal, coke, etc., withvide a-car wit --"';out necessltatlngflanyalteration of thecar toadaptit to "the hauling of the different figi'aterials.

novel means for retaining a.
amas. 1910.
4 The above objects are attained by utilizin the present type of standard hopper cars an placing partitions therein, which will divide the car into a plurality of compartments, the central compartment having vertical sides directly above the dump doors or gates-of the car. 7 The lowered es of the" partitions are provided with flap loors, whereby after theinatr'ialhas been discharged from the central compartment of the car, the load in the other of said compartments will, open the flap doors and discharge, one portion of the load being thus discharged in advance of another portion 'orportions. It is therefore apparent that; with the provision of suitable means in connection with the flap ore, in which type of car the capacity compared to an ordinary hopper car has been sacrificed without materially increasing the general usefulness of the car, it being impossible, in a great many instances, to use these specially designed ore cars other than for a one way transportation.
To obviate 'the necessity of using a specially designed ore car,- as the Summers type, I provide an ordinary hopper car wherein ore can be confined within the center compartment having as large capacity as the specially designed carabove referred to, the pressure of the ore within the compartment being such that its weight is'at its maxlmum to dislodge any material that has a tendency to. cling or adhere to any portion of the car. I
My invention will be hereinafter considered more fully in detail, and then spec fically claimed, and reference will now be had to the drawing forming-a Part-ofthIs" apferred embodiments of my invention -but I would have it -understood gthat the-detail construction" thereo'fcan; -be" fva-riedi -or orrscope of the inVentiom Referring to the drawings :'--Figure 1*is an elevation of a a car constructedin accord 'ance with my i1'1vention,'-Fig. 2 is a plan of the same, Fig. 3 is a longitudinal sectional view of a portion of the car, Fig. 4 is an elevation of a .portion of the ar equipped with a flap door lock, Fig. 5 is a cross sectional view of the car illustrating one of the partitions thereof provided with two flap doors, and Fig. 6 is a similar view illustrating a single flap-door. I
In the accompanying drawings, 1 designates a car frame supported by trucks 2, said frame supporting a metallic" hopper, rectangular in plan and consistingof side walls 3, inclined end walls 4, and a longitudinal center sill 5, all of these parts being common to an ordinary hopper car body.
6 designates transverse vertical partitions having the vertical edges thereof suitably secured to the inner sides of the walls 3, said partitions'extending from the upper edges of the side Walls downwardly to approximately half the height of the side walls 3, and dividing said car into three compart ments 7, 8 and 9, the compartment 8 having all walls thereof vertical, while the compartments 7 and 9 each have an inclined end wall serving functionally as the bottom of each compartment, The partitions 6 are provided with central verticalstrengthening reinforcements 10 which are connected to the inclined end walls 4 by angularly disposed braces 11,
said-1' braces being located centrally of the compartments 7 and 9, and connecting with the reinforcements contiguous to the upper ends thereof. The braces 11, similar to the center sill 5, are of an inverted V-shape in cross section in order not to interfere with the discharge of the contents of the compartments of the car.
The space below the lower edges of the partitions 6 constitute discharge openings 12 'for the compartments 7 and 9, and movably arranged in said openings, are flap doors or gates 13 preferably secured to the partitions 6 by hinges as shown. In some instances, each partition can be provided with two discharge openings and two doors, as shown in Fig 5, while in other instances, each partition can have a single discharge opening with a single door cut away to clear the center sill 5, as shown in Fig. 6. The inwardly swinging movement of the flap doors or gates 13 may be limited by projections 14, carried by the inner sides of the walls 3 adjacent to the lower edges of the inclined end walls 4. The inward movement of the doors or gates can also be limited by simi-, lar projections 15 carried by the center sill 5, or by the lower edges of the inclined end walls i To lock the doors or gates 13 from swinging outwardly into the compartment-B, suitable latches or pins. 16 can be employed, said pins bein locatedin the frame 1 of the car to extend into the body of .thecar and be engaged by the doors or gates.
Suitable drop or dump doors17 of the orcar 1s. as follows: Material is first placed in the compartment 8 and as the material enters said compartment, the doors or gates 13 are forced outwardly against the projections 14 and 15, and arerfirmly held against said projections as long as the material remains in the compartment 8. The compartments 7 and 9 can then be filled, the doors 13 the compartment 8, and it is apparent that the capacity of the three'compartments 7, 8 and 9, is equivalent to the ordinary hopper car.
In the construction herein shown, the
, stops 14, 15, are so positioned that when the.
load is in compartment 8, the doors 13 will assume an inclined position with'respect to the partitions 6, before the doors engage the stops 14, 15. Butthis is not essential to the eitectual operation of the device, as the stops may be located in such position that the doors 13 when the compartment 8 is filled,
will hang in vertical alinement with the partitions 6. r
Then the contents of the car are to be discharged, assuming that all of the combeing held against movement by the load in partments are loaded, the doors 17 are released and it is obvious that the contents of the compartment 8 will immediately discharge, since all slopes and inclined walls are dispensed within connection with this compartment, and the contents thereof al- .lowed to discharge by gravity. Immediately upon the discharge of the contents of thecompartment 8, the-weight of the load within the compartments 7 and 9 causes the flap doors or gates to swing open or into the I compartment 8, whereby the contents of the compartments 7 and 9 can immediately follow the contents of the compartment 8. lVhen the load passes out of the compartment 8, the doors or gates 13 are free to swing inwardly toward each other and since these doors act, when in closed position, .to hold the load in compartments 7 and 9, it" will be evident that the contents of these compartments are free to discharge.
It will be noted that with a compartment hopper car as above "described when ore scale, fine dust, and materials of high specific gravity, but of an adhesive and bridgin'g nature are placed in the central compartment, they will dump asreadily' as coke, coal and other loose material of lowerspecific gravity.- This is accomplished withoutlessening the cubical capacity-required for the lightermateriah', thus eliminating the need of special cars for ore. Furthermore,
the partitions of thegcar add rigidit "and I maintenance.
Having now described my invention what I claim as new, is
1. A car of the type described, comprising a body provided with a discharge opening in the bottom thereof, fixed partitions dividing said body into compartments, doors hinged to the lower edges ofsaid partitions and-adapted to be held iii a closed position by a portion of the lading for retaining another portion of the lading within said body; said doors free to open automatically under the pressure of the lading in one compartment when the lading in another compartment is discharged, and eachcompartment discharging direct through the discharge opening Without passing through any other compartment.
2. A car of the type described, comprising a body provided with a dischargeopening and having a fixed partition forming compartments, doors controlling the discharge of a load from said com artments, and a second door hinged to said fixed partition and arranged to be held closed by the weight of the load in one of the compartments, and being free to open automatically when the load in the last-named compartment is discharged, each compartment discharging direct through the discharge opening without passing through any other comdpartment.
3. A car of the type describe a body having a discharge opening and having fixed partitions dividing the car into compartments, and hinged doors carried by said partitions and adapted to be held in a closed. position by a portion of the load within said body, said hinged doors being free to open when the door-holding portion of the load is discharged, and each compartment discharging direct through the discharge opening without passing through any other compartment.
4. In a dump car, a car body of hopper form having a bottom discharge opening, 'and swinging doors disposed transversely of the car body within the same anddirectly above the discharge opening adjacent the ends of the latter forming a central compartment and end compartments in the car body, the end compartments being in direct communication with thdbottom discharge opening when the doors swing open.
In testimony whereof I afiix my signature in the presence of two witnesses.
