KOFFER-CAR.
Specication of Letters Patent.
Patented Oct. 15, fgi.
Application led May 14, 1917. Serial No. 168,401.
To all whom it may concern:
Be it known that I, ARGYLE CAMPBELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Hopper-Cars, of which the following is a full, clear, concise, and exact description,'reference being had to the accompanying drawings, forming a part is a tedious and expensive operation or, the
practice has sometimes been employed of introducing a steam jet into the body of frozen ore. The latter process requires that the -steam be injected into the ore at different points and is an ineiicient operation inasmuch as the greater portion of the steam escapes and furthermore, it is difficult to introduce the steam in the middle or central portions of the load where the ore should be first thawed out.
One object of my invention is to provide an efficient arrangement of hopper-car or ore car which permits the application of heat, as by means of steam, to the load within the hopper to expedite thawing out the frozen ore or other material and thus facilitate its discharge from the hoppers.
Another and more specific objecty of the invention is to provide a hopper car having steam passageways extending around and also through the hoppers and without sacrificing any of the vload-carrying capacityofthe car to thereby increase the rapidity with which the load may be thawed out.
Further objects of the invention are to provide an efficient door operating mechanism more particularly adapted for cars of the type above described and also to impro-ve and strengthen the generalconstruction of the ore type of cars. Y
In the drawings forming a part of this specification, Figure 1 is 'a part side elevation, part longitudinal section on line 1 1, Fig. 4 of an ore car showing my improvements in connection therewith. Fig. 2 is a vertical, transverse sectional view of the car illustrated in Fig. 1 and taken on lthe line 2-2 thereof, Fig. 2 being upon al larger scale than Fig. 1. Fig. 8 is a transverse sectional view, parts being broken away, the section being taken substantially on the line 3-3 of Fig. 1. Fig. 4 is a horizontal sectional view, parts being broken away, and taken substantially on the line 4 4 of Fig.A 1 and illustrating more particularly the arrangement of steam passageways. Fig. A5 is a vertical longitudinal sectional view taken centrally of the car to illustrate the door operating arrangement. Fig. 6 is an enlarged elevation and part section of part of the door operating mechanism.` .And Fig. 7 is a top plan view of a portion of the door operating mechanism.
In said drawings, the hopper car is shown 4 as comprising vertical side walls 10-10; in-
clined end hopper walls 11-11, built up bod bolsters 1 2-12 (hereinafter more particu arly described) center sills 13-13g Z- bar side sills lll-14; Z-bar end sills 15-15; a pair of hinged hopper doors 16-16; door operating mechanism, designated generally by the reference A; and steam passageways, hereinafter described;
. rlhe side walls 10 of the car are extended downvertically and secured to the Z-bar side sills, as indicated at 17 in Fig. 2. At the lower ends of each of the side walls, inwardly and downwardly inclined plates 18-l8 are employed, the latter being secured at their upper edges to the side walls 10 and at their lower` edges to the inner flanges of the Z-bar side sills, as indicated at 19, thereby forming outside, longitudinally extending triangular shaped passageways B--B. The inclined end hopper sheets 11-11, just above the center sills, have s ecured thereto vertical, transversely extending pressed plates 20-20, on the under sides of the end hopper walls which, in conjunction with horizontally and transversely ex-l tending plates 21-21 also form triangular shaped passageways lC---C that extend transversely of the car and which are also in communication with the outside passageways B-B, as most clearly illustrated in Fig. 4. As will be. understood, the transverse passageways C-C are closed at their outer ends by the side sheets of the car, one
1 of the passageways C, however, having an inlet orifice 22 at one side of the car through,
' versely and longitudinally so as to form four discharge openlngs, twoon each side of theI center still, as will be understood from an'in-` spection of Fig. 4. The longitudinal division is formed by a pair of inclined longitudinal sheets 24--24 mounted on the tops of the center sills 1,3-13, as clearly appears' rfrom Fig..2 and said sheets 24--24 in conjunction With a horizontal 'plate 25 mounted fon the tops of the sills 13, form a center or intermediate :longitudinally extending pas'- sageway D,'the same being in communication with the'end passageways C-C, as. appears from Fig. 4. The transverse division wall of the hopper is formed by a pair of trans# versely extending plates each having a lower vertical portion 26 and an upwardly inclined portion v27, as a pears from Fig'. 5. The vupper portions 2 of said transversely extending plates in conjunction with another horizontal transverse plate 28 form a center orintermediate transversely extending passageway E, the same 'being in communication with the longitudinaly passageways B-B and D, as clearly appears from Fig. 4. In connection withv all of Athe foregoing described passageways, it will be understoodl that the plates are cut away at the. junction points in order 4to provide the necessary communication.
`WithV the arrangement above described it is apparent that when steam or other suitable heating medium is introduced through the orifice 22, the steam will circulate entirely around the hopper closely adjacent the door openings and also through the load, .both longitudinally and transversely', and at the same level. ln this manner, heat is applied to the load within the hopper over an extended area, thus facilitatin the thawing outprocess. Furthermore, t e steam passageways are so disposed that the load-carry ing capacity of the car is not lessened nor is the expense of the carconstruction incident to the passageways appreciably increased.
It is also apparent that all of the plates employed in forming the steam passageways in l crease materially the strength of the car.
-Each of said hopper doors 16-1'6 extends across two of the vdischarge 'openings and each door 16 is pivoted about a longitudinal axis at the side of the car, as indicated at 29, the hinge points bein locatedbeneath the Z-bar side sills 14. long their inner edges, the doors 16 are strengthened by suitably constructed bracing bars 30, the latter being extended slightly beyond the doors at Iof chains is properly guided on the sheavewheel by a central annularA rib 34.` The ends of each pair of chains 31 are connected to a balancing or equalizing linkA 35, each link 35 in turn being connected to a hook-shaped link 36, the latter in turn being pivotally connected to a short link 37, each short link 37 being connected to another. link 38 and each of the latter in turn bein connected to alever arm 39 formed integra ly with ahub 40 mounted on a transversely lextending operating shaft 41. As clearl appears lfrom Fig. 6, one set of links, 36, 3 and 38, winds under theshaft 41 and theother set over the shaft 41 in closely adjacent vertical planes tothereby neutralize the torsion on' the shaft when the doors are in closed position. As
Will/be understood, the hub 40 and linksv immediately associated therewith, together with the inner ends of thechain's 31, are located `between the center sills, and in order to provide the necessary clearance for the ends of the lever arms 39 when vtheshaft 41 is rotated, the cover plate 2 '5 is cut away, as indicated at 42 in ig. 4, and while this opening 42 may permit-escape of a slight amount of steam, the amount which can pass therethrough' is comparatively small and may be neglected in actual practice.
The shaft 41 is extended to both sides of the car and is provided with suitable squared ends 43 by which it may be rotated in the usual manner by a claw-bar or other suitable tool. The 'operating shaft 41 is provided with suitable ratchet and pawl mechanism,
vthe latter being operable from either side of the car by means of a transversely extending auxiliary shaft 44 which extends through the central passageway E. A detailed description of the pawl and dog mechanism which is operable from either side of the car, will be found in my patent for improvement in door operating mechanism, No. 1,255,385 granted February 5, 1918.
Each o the holsters of the car comprises a' vertically extending plate 45, saidl plate extending up tothe inclined end wall 11 of the hopper and being suitably reinforced by vertically lextending angles`46 and also at the bottom by horizontally extending angles 47. Each 'of the bolsters 12 is also braced byl suitable plates and angles 48 extending from'the vertical plate 45 to the adj acentinclined end wall 11 of the hopper. At the ends of each of the hopper doors 16, near the outer sides thereof adjacent the hinges, downwardly extending plates 49-49 are provided to prevent discharge of any of the load to the outer sides of the rails and thus insure the complete discharge of the load Within the rails when the doors 16 swing open.
Although I have herein shown and described What I now consider 'the preferred manner` of carrying out my invention, the same isfmerely illustrative and I contemplate all changes and modiications that come Within the scope of the claims appended hereto.
I claim:
1. A hopper car having inclined end hopper sheets, transversely extending vertical and horizontal sheets beneath said end hopper sheets and forming therewith transversely extending passageways adapted to receive a heating medium 'therewithin 2x A hopper car having inclined end hopper sheets, transversely extending vertical and horizontal sheets beneath said end hopper sheets and forming therewith transversely extending passageways adapted to receive a heating medium therewithin, and a longitudinally extending passageway in communication With said transversely eX- tending passageways.
3. A car of the character described having a central hopper and three transversely extending triangularly shaped passageways and three longitudinally extending triangularly shaped passageways, the intermediate longitudinal and intermediate transverse passageways extending through the hopper and being relatively shallow, said passage- Ways being adapted to have a heating medium introduced therewithin.
4. In an ore car, the combination With a single hopper divided longitudinally by the center sill and transversely by a transverse partition, of steam passageways. extending around and through said hopper, said transverse partition being utilized for one of said steam passageways, of hopper doors, and devices for operating said doors including means disposed within said transversely extending partition.
In Witness that I claim the foregoing I have hereunto subscribed my name this 28th day of April, 1917.
