DUMPING Box-CAR.

SPECIFICATION forming part Ovf Letters Patent No. 734,977, dated July 2S, 1903. Application filed August 15, 1902. Serial No. 119,793. (No model.)

10 all whom, t may concer/t.

Be it known that I, GLENN E. SIMoNToN, a citizen of the United States, and a resident of Vanwert, in the county of Vanwert and State of Ohio, have invented a new and Improved Dumping Box-Car, of which the following is a full, clear, and exact description. Y

My invention relates to improvements in dumping box-cars especially adapted for the transportation of materials in bulk, such as coal and grain, although the car may be used for carrying coke, ore, and any other loose dumpable material.

The primary object of the present invention is to produce a twin or double hopper dumping-car with means for securely closing the filling or loading openings in the roof for the purpose of excluding rain and the Weather from the grain or other bulky material loaded into the car. The roof-doors are constructed to open freely in order to fully expose the filling or loading openings, and they are arranged to fold snugly over said openings to effectually close them, special provision being made to thoroughly close the joint between the meeting edges of the doors for the more perfect exclusionof the weather.

A further object of the invention is the provision of novel hopper-doors especially designed to securely close the dischargeopenings against the leakage of grain or other loose bulky material loaded into the car, said doors adapted when opened to assume positions which permit the granular material to discharge freely and practically without obstruction from the doors. The inward movement of each door when closed is arrested by a stop, the latter being fashioned to allow the free passage of the granular material, so that it will not lodge against the stop.

A further object of the invention is to provide a door-actuating mechanism for the series of hopper-doors, said actuating mechanisin serving to hold the hopper-doors se- 1 curely locked in their closed positions and said mechanism being operable to easily open all the doors of the group simultaneously.

A further object is to provide means for locking the roof-doors intheir closed positions, said locking devices being held when adjusted in operative engagement with the doors by detents or catches which are automatically effective on the adjustment of said locking devices.

A further object of the invention is to construct the carin a manner to secure strength and stability throughout the several parts, particularly at the roof thereof, such roof-rafters or carlines being fashioned at points where they are exposed through the illing or loading openings in a manner as to prevent lodgment of the granular material.

I shall hereinafter describe the car as constructed of metallic plates andbeams or stays; but while metal of a suitable nature may be advantageously used in the construction it is evident that wood or other appropriate materials may be employed.

To thc accomplishment of these ends the invention consists in the novel construction, arrangement, and combination of parts,which will be hereinafter fully described, and the actual scope of the invention will be defined bythe claims. y

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of a dumping box-car constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional elevation taken centrally through the improved car. Fig. 3 is a vertical transverse section on the line 3 3 of Fig. 2. Fig. 4. is another vertical transverse'section through the car, taken in the plane of the dotted line 4 4 of Fig. 2. Fig. 5 is another vertical trans- Verse section with the lower part of the car broken away, the plane of the section being indicated by the dotted line 5 5 of Fig. 2. Figs. 6 and 7 are vertical sectional elevations, on an enlarged scale, illustrating two of the hopper-doors and their actuating mechanism, Fig. 6 showing the doors in their closed positions, while in Fig. 7 the doors are shown in their open positions. Fig.- 8 is a detail plan view of the hopper-door-actuating mechanism, the hopper-doors being omitted and the hangers being shown in transverse section. Fig. 9 is a .detail plan* View of a portion of the roof or deck of a car, illustrating' the means for locking the roof-doors in their closed positions. Fig. lO is an enlarged detail fragmentary vertical section through another embodiment of means for securing a tight joint between the hopper and its door, and Fig. 11 is a vertical sectional View through a portion of the roof or deck of a car and illustrating another embodiment of means for adjusting the roof-doors.

The body A is carried by the longitudinal sills a, adapted to be mounted on a runninggear of any suitable character. As is usual in twin or double bottom dumping-cars, the body is divided, as at d in Fig. 3, such division lying at the middle portion of the bottom. The bottom of the car-body takes the shape shown more clearly by Fig. 2, by reference to which it will be seen that the bottom consists of the outwardly and downwardly inclined members b b' and the downwardly and inwardly inclined members b2 b3, such inwardly-inclined members being much longer than the outwardly-inclined members b b and the members meeting in pairs in a manner to form the twin or double hoppers. The sides and ends a2 CL3, respectively,'are preferably made of metal plates joined together in any usual or preferred manneras, for example, by riveting the parts-and the sides of the car-body-are reinforced by the provision of a series of vertical stays 5, the latter being riveted to the outside of the walls and consisting of angle-irons. As shown by Fig. 1, the angle-iron stays are united to the longitudinal sill d; but this is optional. The roof or deck of the car-body consists of the longitudinal side plates c c', the end cross-plates c2 c3, and the middle cross-plate c4. The side plates are arranged in the inclined positions shown more clearly by Figs. 3, 4, and 5, so that they slope downwardly and outwardly, and these side plates preferably extend throughout the length of the car. The side plates are provided at their outer `lower edges with downwardly-extending flanges 6, arranged to overlap the upper edges of the side walls CL2, and these side walls and the side plates of the deck or roof are united by riveting them together. The inner edges of the inclined side plates forming a part of the deck or roof do not meet with one another; but they are separated and provided with upwardly extending iianges 7. The middle cross-plate c* of the deck or roof extends -across the opening between the upwardlyflanged inner edges 7 of these side plates c c, and the end plates c3 are disposed to also extend across the opening provided by the iianged edges 7, said transverse plates c2, c3, and c4 being riveted or otherwise united to the side plates of the deck or roof. The end plates c2 c3 are also flanged and riveted to the end walls d3 of the car-body. From this description it will be seen that the inner edges of the side plates c c and the transverse plates d2 c3 c4 provide in the deck or roof two longitudinal filling or loading openings B B', the same being separated by the flanged middle cross-plate c4.

rIhe'roof or deck formed by the metallic plates just described is reinforced by the employment of a series of transverse rafters or carlines S, 9, andv 10. (See Figs. 2, 3, 4, 5, and 11.) Each rafter or carline is made in a single piece of channeled metal, preferably from pressed steel, and said rafter or carline has inclined members joined by a central crest member. The rafters (indicated at 8 and 9) extend across the loading-openings B B', and these rafters are pointed, as at S in Figs. 8, 4f, and 11, said pointed parts of the rafters minimizing the lodgment of material when it is being loaded into the car through one of the filling-openings. The other rafter (indicated at 10) lies beneath the middle transverse plate c4 of the deck or roof, and it is provided with a long horizontal portion 10. (Shown by Fig. 5.) The rafters are securely riveted to the side members c c of the deck, and at their end portions they are united to the vertical stays 5 on the side walls, such union between the stays and the rafters being preferably eifected by the employment of rivets, which pass through the upper ends of the stays, the side walls of the car-body, and the' end portions of the rafters. It will be seen that the side walls and the deck or roof are stayed and reinforced by a metallic skeleton framework consisting of the series of vertical stays and the series of rafters, thus materially increasing the strength and stability of the car-body.

The filling or loading openings B B' are adapted to be tightly closed by the employment of doors in order to protect the material loaded in the car from the action of the weather. I have preferably arranged these doors in pairs, (indicated at C C' and D D.) The doors C C/ are adapted to close the opening B, while the other pair of doors serve to close the other illingopening B'. These doors are preferably arranged to swing inwardly toward each other, although, if desired, the doors may be mounted on the roofplates c c to slide thereon, asin Fig. 11. The swinging doors are connected to the roofplates c c by hinges, which are of the class known as link-hinges, in order that the doors may swing outwardly from the iiangcd edges 7 of the deck-plates in a manner to fully expose or open the loading-openings B B. The detailed construction of these hinges is shown more clearly by Fig. 1, from which it will be seen that each hinge consists of a member 1l, adapted to be fastened to the deckplate, another member 12, fastened to one of the doors, and a link 13, which is pivoted to the members 11 12. A series of these hinges, preferably two in number, is employed to connect each door to the deck-plate, and the hinges thus provide two points on which the door can swing or turn on horizontal axes. Each door is provided with a downwardly-extending iange 14: at its outer edge, said flange varranged to overlap the upwardly-extending 'flange 7 of the deck-plate. The door C or D of each pair is provided at its inner free edge ICO with the downwardly-extending lip or flange 15, while the companion door C or D of the pair is provided at its inner edge with an upwardly-extending lip 16 and with a supplemental or auxiliary lip 17, said lips 16 and 17 being disposed in parallel relation, so as to form a channel or trough adapted to receive the downwardly-extending lip 15 of the firstmentioned door. This construction requires that the door C or D shall first be closed over the filling-opening in a position to present an open channel or gutter to the flange 15 of the other door C' or D'. The door which is provided with the single lip or flange 15 is equipped with a shield 1S, the latter being united in any suitable way to the outside of the door C or D and arranged to extend beyond the flange 15, said shield adapted to extend over the joint between the flanged edges of the doors when closed, thereby eifectually excluding rain or snow at the channel or gutter on the door C or D. From this description it will be seen that the doors are hinged to the deck or roof in a manner to closely t around the flanges 7, and the meeting edges of the doors are securely closed by the flange 15 entering the channel or gutter between the flanges 16 17 and by the shields extending over the joints.

I have also provided a novel locking contrivance for holding the pairs of doors in their closed positions, one of these locking contrivances being located at the ends of the pairs of doors, as shown by Fig. 1. The contrivance which I prefer to employ consists of the rock-shaft 20, arranged transversely across the deck or roof at the middle portion thereof, said rock-shaft being journaled in bearings or straps 19, which are attached to the end plates c2 or c3 or to the middle cross-plate c4. (See Figs. 1, 2, and 9.) The rock-shaft is provided at points intermediate of its length with the lips or studs 21, arranged to overlap projections on the end portions of the doors, and one of these lips may be provided with an aperture adapted to receive a seal 22, the wire of which seal may pass through a projection on one of the doors, as indicated substantially by Fig. 9. The rock-shaft 2O is also provided at one end portion with a crank-arm 23, which is arranged to turn downwardly between a pair of plates or standards 2l 25, the latter being secured firmly to one of the deck-plates, as c. These standards are spaced far enough apart to receive a crank-arm of the rock-shaft, and on one of the standards is mounted an automatic latch 26. I prefer to pivot the latch to the standard 25 and to arrange the short arm of said latch in the path of the crank-arm on the rock-shaft, whereby the latch is adapted to be turned on its pivot when the rock-shaft is turned into locking engagement with the doors, said latch being adapted to automatically engage with the crank-arm and to return to its raised position byA gravity, the outer longer end of said latch bearing against the deck-plate in order to hold the latch normally in its operative position.

It will be seen that the rock-shafts may be easily manipulated to withdraw the lips or studs 21 from engagement with the doors, it being necessary to first release the latches from the crank-arms 23, whereby the doors may be released ain/d thrown to their open positions in order to expose the loading-openings; but when it is desired to close the openings, the doors should be folded inwardly and the rock-shaft should be turned in a direction which will bring its lips or studs 21 into engagement with the doors and its crank-arm into engagement with the latch 26.

The deck of the car is provided with running-boards, as indicated at 27 28. As shown by Figs. 1, 2, 3 and -l of the drawings, these 'running-boards may be fastened to the doors which close the filling-openings, so that the running-boards may be adjusted out of position when the doors are open; but I do not desire to limit myself to the employment of the running-boards on the doors, because I am aware that the running-boards may be secured to the inclined side members c cof the deck or roof, as shown by Fig. t.

The members b b of the bottom are provided with the discharging-openings E E', each member b b being provided with an outwardly-extending flange 29, which surrounds the discharging-opening. The members b o' are also provided with the stop strips or blocks 30, the same being secured to the hopper-bottom within the discharging-opening. Each stop strip or block is made from a single piece of an gle-iron and secured within the hopper-bottom, so as to present a sloping face to the material, while an abrupt shoulder or ledge is formed in the path of the hopperdoors F F'. It will be understood that the hopperbottom is provided with four disch arge-openings, two of which are in the members l) Z1 on one side of the division d', while the other discharge-openings are in the members l) b on the opposite side of the division a. The hopper-doors F F are connected in pairs with an actuating mechanism, to be presently described, and the hopper-doors are hinged individually to the members b b', such hinges being indicated at 31 and located at the upper edges of the doors. The hinges may be of any substantial construction approved by those skilled in the art, and they serve to fasten the hopper-doors directly to the members Z) b of the hopper-bottom. These members are also provided with reinforcement-plates 32, which are preferably of angleiron and riveted to the members along the upper flanged edge 29 thereof and adjacent to the points where the hinges 3l are fastened, said stays serving to reinforce that part of the hopper-bottom to which the doors are hung, because the hinges 31 are fastened to the stays as well as to the hopper-bottom.

Each door F F" is provided with a marginal IOO iiange 33, and the upper edge of the door is reinforced by a stay 34, similar to the stay 32 on the hopper-bottom, thus making provision for the substantial attachment of one leaf of the hinge 31 to the hopper-door. The hopperdoors F F are arrangedl to close inwardly within the iiange 29 of the discharge-opening, and the joint between the lower edge of the flanged door and the iianged discharge-opening is adapted to be securely closed by yieldable members, which may be provided either on the free edge of the door or on the lower iianged edge of the discharge-opening. In Figs. 6 and 7 of the drawings the yieldable members are represented in the form of metallic plates 35, which are bent or doubled, so as to overlap the inner face of the door and provide an edge for the passage of rivets by which the bent plate may be securely attached to the door. The angular free portion of the plate forming the yieldable member is and the yieldable member 35.

disposed in opposing relation to the flange 33 of the door, and it lies at an incline or angle thereto, whereby the yieldable member is adapted to frictionally engage with the fia-nge 29 of the discharge-opening. If desired, this yieldable member may be extended or carried around three of the side edges of the door; but in Figs. 2, 6, and 7 I have shown the yieldable memberV at the free edge only of the swinging hopper-door.

In Fig. l0 of the drawings I have illustrated another embodiment of means by which the tight joint between the door and the hopperbottom may be secured. In this iigure of the drawings the section 36 of the hopper-bottom is provided with an offset keeper-flange 37, which is applied to the outer or under face of said plate 36, while the yieldable member 35 is bent so as to lie within the space formed between the keeper-flange and the hoppersection 36, said yieldable member having an edge portion 35b extended over the upper inner face of the hopper-section 36, whereby the keeper-flange and the yieldable member may be riveted by a single row of rivets to the hopper-section 36. The door F2 is bent at its lower edge to form the iiange 38, which is-reinforced by a stay-plate 39, and against the under face of the door F2 is applieda shieldplate'40, the lower edge of which is extended or prolonged beyond the ianged edge 38 of said door. A'stop-strip 4l is itted over the vstayplate 39, and this stop-strip, the stay- Ireceive the doubled edge of the yieldable member 35 between the stop-strip 4l and the stay-plate, while the flange 38 and the ottstanding portion of the stay-plate are adapted to enter into the space between the keeper 37 This makes the yieldable member engage frictionally with the stay-plate, while the door-flange 38 engages in a similar way with the keeper 37, and the edge of the shield-plate extends beyond the overlapping frictional joint between the hopper-bottom and the door, whereby the escape of material is effectually prevented through the door-opening of the hopper-bottom.

It will be seen that the j onts between the hopper-openings and the doors are eiectually closed bythe provision of yieldable members, and in order to prevent leakage of material between the upper hinged edge of the hopperdoors I prefer to extend the sections b b of the hopper-bottom across the joint at the upper edge of the door-opening, such extensions being indicated at b5 in Figs. 6 and 7.

42 indicates the hangers, which are firmly secured to the inclined sections b b of the hopper-bottom, said hangers being located on opposite sides of the division a in the car-bottom. Each hanger is constructed of channeled metal in the form of a stirrup or yoke, as shown more clearly by Figs. 6 and 7, and said hanger being iianged at its ends for secure attachment to the hopper-bottom. The hanger is provided with a vertical slot 43, through which passes a shiftable bolt or spindle 44, the latter carrying an idle chain-wheel or grooved pulley 45. This pulley or chainwheel is loosely mounted on the bolt or spindle, and it is arranged to travel with said spindle freely through the s lot 43 in a vertical direction when the door-actuating mechanism is operated.

The bolt or spindle 44 serves to pivot-ally connect the inner ends of two pairs of links, (indicated at 46 46 and 47 475k) One pair of links, 46 46, is pivotally attached, as at 46, to angle-plates 48, firmly secured to the under face of one of the doors F, while the otherpair of links, 47 47 are similarly pivoted at 47 b to other angle-plates 49, secured firmly to the other door F. (See Figs. 6, 7, and 8.) r The links forming each pair are disposed in converging relation, as shown byFig. 8, in order to bring the inner ends of the two pairs of links into overlapping order and compactly dispose them with relation to the bolt 44 and the chain-wheel 45, whereby the inner ends of the two pairs of links may be united pivotally by a swinging bolt or spindle. I prefer to make each link 46 46 47 47 in sections and to thread the inner ends of the linksections in a manner to receive a couplingsleeve 50, the latter being interiorly tapped with right and left hand threads adapted to engage with similar threads on said link-sections and to be rotated thereon in one direction or the other for the purpose of lengthening or shortening the link, whereby the series of four links may be extended or contracted to secure nicety in the adjustment of the door-actuating mechanism, so as to firmly close the two doors of the pair.

5l designates a bolt-lifting chain which is connected by a loop or clevis 52 to the spindle IIO or bolt 44, said chain passing upwardly from the bolt and over a guide wheel or roller 53, mounted in the-upper part of the hanger 42, after which the lifting-chain 5l is extended to awinding-shaft 54, said end of the chain 5l being coiled in one direction around said shaft and attached thereto in any suitable way. Another chain, 55, is employed to lower the spindle or bolt 44, said chain being coiled on the shaft 54in an opposite direction to the chain 5l. The lowering-chain 55 is carried in a downward direction from the shaft 54, and it passes beneath a guide roller or sheave 5G, the latter being mounted in the hanger near its lower end. This chain 55 is carried across and in engagement with the shiftable chain wheel or pulley 45 on the arbor or bolt 44, and the free end of said lowering-chain is made fast to the hanger by means of a bolt 57, the latter being secured in the lower part of the hanger and on the opposite side from the lower guide wheel or sheave 56.

The winding-shaft 54 extends through the two hangers 42 and through the inclined middle portion of the hopper-bottom, and this shaft 54has attached to it the winding-chains 5l and 55, which are associated with the two pairs of hopper-doors, whereby one shaft 54 is adapted to operate the actuating mechanisms for the series of four hopper-doors. Any suitable means may be adopted for locking the winding-shaft 54 against accidental rotation, and in Fig. l of the drawings I have shown this shaft as provided at one end with a ratchet 5S, with which is adapted to engage a pawl 59, that is held in its operative position by a detent GO. It will be understood, however, that any suitable form of locking device may be provided for the winding-shaft.

In Figs. 2 and 6 of the drawings the hopper-doors are shown in their closed positions, and the spindle or bolt 44, together with the shiftable sheave or chain-wheel 45, lies at the lower part of the slot 43 in the hanger. To open the hopper-doors, the operator turns the winding-shaft 54 by a wrench or other suitable implement, and thereby winds the chain 5l on the shaft and at the same time unwinds the other chain 55 from the shaft. This operation of winding the chain 5l lifts the bolt 44 and the chain-wheel 45, and the upward movement of said bolt draws the pairs yof links inwardly and upwardly to the positions shown by Fig. 7, whereby the doors F F' are swung to their open positions, the chain 55 taking the position shown by Fig. 7. The material can now be discharged freely through the openings E E in the hopper-bottom, but before the car is again loaded it is necessary to close the doors. This can be easily accomplished by turning the shaft 54 in a reverse direction, so as to uncoil the chain 51 and to coil the chain 55 on the shaft. This chain 55 pulls downwardly on the shiftable bolt 44, be cause one end of the chain is fastened at 57 lower guide-sheave 56. The pull of the chain 55 is exerted on the shiftable pulley or chainL wheel 45 so as to force the bolt 44 downwardly, and the bolt thus acts to press the links in opposite directions, and thereby close the doors F F' within the flanged discharge-open# ingsE E', the joints between the door-openings and the doors being securely closed by the yieldable members and by the extended 'lower edges of the sections Z) b of the hopperbottom.

I do not wish to limit myself to this form of device for operating the hopper-doors, as, if desired, any other suitable device may be employed for the purpose.

Having thus described my invention, I claim as new and desire to secure byLetters Patentl.
