DUMP CAR.

Application filed January 30, 1922. Serial No. 532,733.

To all whom it may concern:

Be it known that I, ARGYIJ'Z Curr-121cm, 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 Dump Cars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in dump cars.

One object of the invention is to provide in a dump car, efficient and relatively inexpensive means for locking the discharge doors in closed position.

A more specific object of the invention is the provision of a door locking arrangement having portions thereof utilized to strengthen certain parts of the car construction which have heretofore been especially liable to injury.

In the drawings forming a part of this specification, Figure 1 is a broken elevational view of a portion of a W-type hopper car showing my improvements in connection therewith. Figure 2 is a vertical, transverse, sectional view of the structure shown in Figure 1, taken at the left of the latter and looking toward the right, only half of the car structure transversely being shown.

Figures 3, 4 and 5 are enlarged detail sectional views corresponding to the lines 33, 44 and 55 respectively of Figure 1. Figure 6- is a side elevational view of a twin door hopper car showing another embodiment of my improvements in connection therewith. And Figure 7 is a vertical transverse sectional view of the ear shown in Figure 6 and corresponding to the section line 7-7 thereof.

Referring first to the construction illustrated in Figures 1 to 5, inclusive, 10 denotes one of the side walls of the car, 11 a side stake, 12 one of the center sills, 13 the longitudinally extending ridge sheet over the center sills, 14 the transversely extending ridge sheet between the sets of hoppers, 15 one of the hopper bottom sheets sloped downwardly from the end of the car toward the center, 16 an inner hopper side sheet, and 17 an outer hopper side sheet, the latter being sloped downwardly and inwardly toward the center line of the car. Aswill be understood by those skilled in the art, there are four hoppers similar to the one illustrated, two on each side of the-center sill and arranged in pairs extending transversely of the car.

The hopper side sheets 16 and 17 are suitably flanged along their edges surrounding the discharge opening to provide the necessary strength as indicated at 16 and 17 respcctivcly, and the lower edge of the bottom sheet 15 is reinforced by a transversely extending angle iron 18 secured on the under side thereof. Each hopper discharge OPBI'I- ing is adapted to be closed bv a sheet metal door as indicated at 19, the latter being hinged along their upper edges to swing about axes extending transversely of the car. In the arrangement shown, each door 19 is hinged to a combined hinge butt and floor sheet stiffener 20, similar to that more specifically described and claimed in my copending application Serial No. 521,292 filed December 10,1921, now Patent No. 1,437,091, granted November 28, 1922. Secured to each transversely alined pair of doors 19, adjacent the free edges thereof and parallel thereto, is an angle iron 21 providedwith an enlarged or bulb edge 21. The bulb angle iron 21"is secured to both transversely alined doors of a set so that the latter are operated in unison. In the corner defined by the bulb iron 21 and the outer side edge of the door, is a pressed plate 22 riveted to' the door proper and the iron 21 so as to provide additional strength. Where the outstanding flange of the bulb iron 21 passes the flanged outer side edge of the door 19, said bulb angle iron is cut away as indicated at 21 in Figure 1, it being understood that the bulb iron is extended an appreciable distance beyond the hopper side sheet 17 and the corresponding side edge of the door, to adapt it for cooperation with the latch, about to be described.

To hold the doors in closed position,I employ a latch at each end of the bulb iron 21, only one of the same, however, being shown in the drawing. This improved latch, as shown, comprises, broadl ,abracket A; a latch lever proper B; and a locking cam C.

The bracket A, preferably in the form of a casting, has an inner main web 23 lying against the sloping side sheet 17 and se cured thereto as by the rivets 242 1.' Said web 23 is extended downwardly below the bottom sheet 15 of the hopper, as shown at 23 in Figure 3 and overlaps the corresponding end of the angle iron 18. The bracket casting A is also provided with a transversely extending flange 25 parallel to and rivet/ed to the outstanding flange of the angle iron 18. In addition, the bracket casting is formed with another flange 26 extending under, parallel to and riveted to the hopper bottom sheet 15. Vith this arrangement, it will be noted that the bracket casting A secured unites the hopper side sheet 17, the hopper bottom sheet 15 and the bracing angle 18, at the lower corner of the hopper, thereby preventing the hopper side sheet from tearing out or rusting out at this point, which has been a source of dilliculty in cars of this type, heretofore.

The bracket casting A is provided also with an outer web 27 spaced from and paral lel to the web 23, said web 27 being united to the web 23 by a flange 28 extending perpendicularly between the two webs 23 and 27, so that a housing is provided for-the lever B and cam C. The flange 28 is reinforced at suitable intervals by ribs 29-29.

The latch lever B is pivotally attached to the bracket A by means of a pin 30 which extends through suitable openings in the back wall or web 23 and the web 27. Said pin 30 has a headed inner end which seats within a recess 31 in the back web so that the pin 30 will be held in operative position when the bracket A is secured to the hopper side sheet 17. The lever B swings in a plane parallel to the webs 23 and 27 and side sheet 17. Said lever is provided with a shank having'one section 32 extending upwardly and away from the pivot pin 30 and another section 33 which extends parallel to the hopper bottom sheet 15, when the lever B is in operative position. At its outer end, the lever B is formed with a shoulder 34 adapted to engage and cooperate with the rounded bulb edge of the iron 21, said shoulder engaging the iron 21 at a point closely adjacent the side edge of the door and inwardly removed from the extreme outer end of said iron 21. Said lever B is provided also with an outwardly and laterally extended shoulder 35 so disposed that a bar or lever may be inserted between it and the extended end of the bulb iron 21 so as to facilitate prying the lever B upwardly to release the doors. The outer end of the lever B is rounded or beveled as indicated at 36 so as to act as a guide to lift the lever B when the doors are moved to closed position, said edges 36 being engaged by the bulb angle 21, as will be understood, the levers dropping into operative position under gravity when the bulb iron has passed beyond the shoulders 34.

The locking cam G is pivotally supported between the inner and outer webs of the bracket A on a through rivet 37 which not only acts as a pivot for the locking cam C but also assists in securing the bracket A to hopper sheet. Said cam C is of wellknown form and engages with a rounded edge 38 formed in the lever B on the upper side approximately where the the two sections 32 and 33 of the shank merge.

In the arrangement shown in Figures 6 and 7, transversely extending twin doors 40-4() are employed, pivoted to swing about transversely extending axes. The free edges ot the pair of doors meet, and extending along the under side of each door near its free edge and parallel thereto, is a bracing beam 41 of substantially inverted U shape with.

the sides laterally flanged as indicated at 42-42. The sides of the hopper aresloped inwardly for a distance as indicated at 43 in Figure 7 and thence extended vertically downward as indicated at, 44. Suitable reintorcing plates 45 are secured to the lower edges of the vertical portions 44.

To hold the doors in closed position, I employ the following arrangement. At each end of the brace 41 and within it is secured a forging or casting 46, the latter having an outwardly extending intcgralheavy pin or bar 47 of circular cross section. The pins or bars 47 are extended outwardly beyond the side edges of the door and also beyond the latching device, hereinafter described, so that the outer extended ends of said bars 47 may be used as handles in elevating the doors to closed position.

Cooperable with each of the extended pins 47 is a hook-shaped latch or lever 48 which is pivotally supported at its upper end by a bolt 49 which is housed within abracket casting 50 secured to the vertical portion 44 of the hopper side sheet. Said lever 43 has a shoulder 51 adapted to engage under the rounded pin or bar 47 and hold the door, as will be obvious. The lower edge of the lever 48 is rounded as indicated at 52 so that, in lifting the door to closed position, the levers 48 will be calnmed to one side until such time as the pins 47 have moved high enough to allow the shoulders of the latch levers to drop thereunder under the influence of gravity. Each lever also has an outwardly or laterally projecting pry-oft lug 56.

Cooperable with each latch lever 48 is a locking cam 53 also pivotally supported from the housing bracket 50 by means of a bolt 54. Thebolts 49 and 54 are extended through the side sheets so as to form part of the attaching means for the latch, there being additional rivets 55, as shown in Figure 6, to secure the housing bracket.
