WINFIELD YOST, OF MONTREAL, QUEBEC, CANADA, ASSIGNOR TO NATIONAL DUMP CAR COMPANY, .A. CORPORATION OF MAINE.

DUMP-CAR.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed April 20, 1907, Serial No. 369,289. Renewed October 20, 1909. Serial No. 523,703.

To all whom it may concern.

Be it known that I, VVINFIELD Yos a citizen of the United States, residing at Montreal, in the Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

My invention relates to dump cars, especially to that type of car provided with dumping doors in its bottom; and has for its object to provide this type of car with an improved door operating mechanism and with other improvements hereinafter set forth.

My invention consists in the details and combinations hereinafter described and claimed.

In the accompanying drawingsFigure l is a side elevation of a portion of a dumpcar embodying my invention. Fig. 2 is an end view thereof. Fig. 3 is a transverse sectional view, showing at the left a section of the car near the center thereof and at the right a section of the car at the intermediate cross beam. Fig. 4: is a top plan view of aportion of the underframe, partly in section. Fig. 5 is a detail showing a portion of the operating mechanism. Fig. 6 is a section on the line 6 of Fig. 5. Fig. 7 is a section on the line 7 of Fig. 5. I

In the drawings,1 indicates the metallic center sills of the car, which may be of any desired form. I have shown these sills as composed of longitudinal plates provided with angle bars extending along the upper and lower edges thereof connected by suitable top and bottom plates to form a box girder.

2 indicates the transverse members of the underframe provided along their lower edges with angle irons 3 and on their upper edges with angle irons 4, these cross beams being suitably connected to the center sill.

5 indicates one of the dumping doors, these doors composing substantially the entire bottom of the car. These doors are provided alongtheir front and rear edges with angle brace members 6 and are hinged at 7 to the center sill. Attached to the under side of the door is an inclined track 8 and attached to the underframe of the car is an inclined track 9, this track being connected as shown either to a gusset plate 10 connecting the side stakes to a transverse member of the underframe and projecting below the underframe-as shown at the left in Fig. 3or to the underframe by means of a depending plate 11. It will be noted that the plate 10 forms a connection between the cross tie and side stake, and a gusset for the ends of the cross tie firmly bracing and supporting the parts atthis point. Mounted upon the track 9 is a shaft 12 extending longitudinally of the car. The gusset plates 10 not only serve as a connection between the upper and lower cords of the cross members and the side stake, but also serve as stops for the inner ends of the shafts 12. It will I be understood of course that in cars of this type half of the doors are operated from each end of the car, each shaft 12 extending inward from the end of the car to a point adjacent the center thereof. The gusset 10 projects downward sufliciently to prevent longitudinal movement of the shafts 12, as particularly illustrated at the left-hand of Fig. 3 adjacent the upper part of the supporting track 9. olined track on the under side of the door rests, so that as the shaft is moved upon the track 9 the door is opened and closed, de-

Upon this shaft the inpending upon the direction of movement of V the shaft. This combination of the inclined tracks and themovable shaft for operating the dumping door is not new with me, but is a well-known method ofoperating such dumping doors used in cars of the National? type. I

The shaft 12 is squared at its outer end and carries thereon the two ratchet wheels 21, 22 having the collars 21 and 22 respectively. These collars are placed in proximity the one to the other and form a sliding surface for the operating lever 15, said lever being loosely mounted on these collars. A pawl 33 pivoted on the lever engages the ratchet wheel 21 to operate the shaft as the lever is moved back and forth in a manner locking operation of the shaft. In order to secure the shaft in its upper position, as well as to hold it at any intermediate point during the closing of the door, I provide upon the end of the shaft a second ratchet wheel 22 fixed thereto. Mounted also upon the end of the shaft is a plate 17 through which the shaft passes and at the opposite end of this plate 17 is a plate 18 of a general U-shape surrounding the plate 17. The bolt 34 passes through the plate 17 as well as the U-shaped plate and upon this bolt 34 between the legs of the U-shaped plate is mounted a roller 35 which travels upon the track 9. A plate 23 is mounted adjacent one end of the supporting shaft, and a bent plate 19 having an upwardly extending vertical portion 20 is connected to this plate 23, the end of the shaft passing also through this vertical portion.

It will now be seen that the plate 17, together with the plates 18 and 19, forms a stirrup traveling upon the track 9, the shaft and the roller 34 forming a rolling support for this stirrup. It will also be seen that the ratchet wheels upon the shaft are carried in this stirrup at one end thereof, while a detent pawl 4 pivoted to the upper leg of the U-shaped plate 18 is carried at the other end thereof. This detent pawl 4 acts as a detent to prevent the backward movement of the shaft when the latter is being rotated in a direction to close the door. When the door is closed it is desirable to provide some means, for holding the detent pawl in looking engagement with its ratchet wheel 22. For this purpose I provide upon the operating lever 15 a projection 24 adapted to engage the pawl 4 when the doors are in closed position, as shown in Fig. 2. It will thus be seen that it is impossible to release the pawl 4 from engagement with the ratchet wheel until the lever 15 has first been raised away to approximately a vertical position.

The stirrup extending from the outside of the ratchet wheels to the inside of the rail and traveling upon the rail serves as a guide to prevent longitudinal movement of the shaft and also serves to keep the ratchets in positive relation to each other.

The end sill of my car comprises a plate 25 bent outwardly at its central point, this plate being provided along its upper edge with an angle bar 26 riveted to the plate 25 and along its inner upper edges with angle bars 32 on each side of the center sill. Gusset plates 31 connect the end sill to the center sill, these plates 31 being riveted to the angle bars 32 and to the center sill, respectively. This forms a very strong and secure arrangement at the end sill and prevents the hue kling of the end sill and also prevents the draft sills from spreading or buckling. At the corners of the car I provide a gusset plate 27, extending down beyond the floor line, this gusset plate being suitably connected to the end sill by angle pieces 28 on the exterior and by channel pieces 29 on the interior of the end sill, and to this gusset plate 27 is attached the push pole pocket 38, this push pole pocket being also attached to the bottom angle 39 of the side girder, whereby the strain of the corner is thrown upon the side girder direct.

I11 order to insure the rotation of the operating shaft, I provide chains 13 and 14, the chains 14 being wound upon the shaft when the latter is in closed position while the chain 13 is unwound. As the shaft rotates the chain 13 is wound and the chain 14 unwound. This arrangement of chains is the same as shown in the United States Patent to Hart & Malt-by No. 780,747.

It will be seen that I have provided a car with a very simple and eflicient operating mechanism in which the operating shaft is guided, longitudinal movement thereof prevented, and in which the various parts of the car are strengthened to resist the shocks and strains incident to service. It is believed that the operation of my car may be understood without further description.
