11 claims.

This invention relates generally to railway hopper cars and has particular reference to hopper doors or gates and mounting and operating means therefor.

One object of this invention is the provision of a hopper car having means by which the hoppers may be quickly and tightly closed in such a manner as to prevent the loss of lading particularly very fine dry commodities such as ne coal, grain or cement.

Another object of this invention is the pro-Y Vision of a railway hopper car having a door or a gate for closing the hopper and simple and quick operating means for shifting the door to either open or closed position.

Still another object of this invention is the provision of new and improved means for actuating the gate or door of a hopper.

A further object of this invention is the provision of a new and improved railway hopper car.

A still further object of this invention is the provision of a new and improved hopper door and operator therefor which is comparatively in expensive to manufacture and which is strong and durable in operation.

Other objects and advantages of this invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which; A

Figure 7 is a sectional view through the lower portion of a hopper showing a modified form of the invention;

Figure 8 is a front elevation of the modification shown in Figure 7, and

Figure 9 is a sectional view on the line 9 9, Figure 7.

Referring now more particulaily to the draw- 5 ings in which similar characters of reference designate similar parts in the several views, the car of the present invention comprises a body including side walls 2, a center sill 4 and bolsters 6. The side walls and bolster may be of any prel0 ferred or desired construction and the center sill, in the instance shown, comprises a pair of channels connected by top cover plate l. Arranged on opposite sides of the longitudinal center line of the car body are hoppers indicated generally 15 at H, the inner walls 8 of which depend substantially vertically from the respective channels of the center sill as shown clearly in Figure 1. The hoppers H also include outer walls I0 and side walls I2.

` of the several walls of the hoppers it is apparent that the load is discharged between the track rails.`

The present invention is designed to provide means which can be quickly and easily operated 25 to provide a tight closure for the discharge end or outlet of each hopper. Inasmuch as the means are identical for each hopper a description of one will suffice for all. As clearly shown in the drawings the means for closing the discharge 30 end of the hopper comprises, in the main, a door frame casting indicated generally as A and a door or gate indicated generally as B, the door B being 'slidable relative to the frame A and having a door operating device mounted thereon as more specifically described hereinafter.

' The door frame A comprises a casting and is preferably of the form shown more clearly in Figures 2, 3, 4 and 5 wherein it can be seen that the casting is generally of rectangular shape to t 40 around the lower edge portions of the hopper walls. As shown in Figure 2 the rear portion I4 of the door frame casting A is substantially vertical and rests against the inner wall 8 of the hopper at the lower edge portion of the latter. The side and front portions of the frame A have attaching portions I6 inclined in accordance with the slope of the front and side Walls of the hopper and rest ing against the latter; said door frame being welded as at I8, or otherwise suitably secured to said hopper walls. The remainder of the side and end portions of the frame A depend vertically below the lower edge portions of the hopper Walls and are indicated in the drawings at Due to the specific arrangement 20` 26 and have secured Vthereto suitable flexible gaskets 22 by means of retainer strips V24 and fasteners 26; the gaskets 22 engaging the upper surface of the gate or door B as clearly shown in Figures 2 and 4 to furnish a seal to prevent leakage. Y

Formed with the side portions of the frame A are inwardly facing channel shaped tracks Vor guides V28 which support the gate B for sliding movement as presently to be described.

The gate B comprises a main or body portion 30 having its side edge portions upwardly and then outwardly iianged as shown at 32 ,and 34 respectively; the side edge portions of the gate B thus being offsety and,l as clearly shown in the drawings, particularly Figs. 3 and 4, arranged within the channel shaped tracks or guides 28. Supported by the vertical iianges 32 of the gate B and by bearing members 36 depending from the outwardly projecting or horizontal flanges 34 are axles 38 supported by rollers 46 mounted on the inwardly extending lower flanges 42 of the tracks'28 and shiftable thereon for opening and closing the door B". In the instance shown in Figs. 2 and 5, three rollers 49 are provided along opposite sides of the gate B but this is merely by way of example as obviously the number of supporting rollers may be varied in accordance with requirements. y

The tracks 28 extend outwardly` beyond the hopper (see Fig. 5) in order to support and guide the gate or door B to its fully open position and a transversely arranged tie 44 is provided .Y beneath the forward end portion ofthe door frame casting A and preferably, though not necessarily, is formed integral with said casting .and serves as an abutment with which a stop 46 secured to the lower surface of the door at its i. forward end portion is adapted to contact to limit the extent of opening movementV of the door. The tie 44 is provided with angle shaped lugs 48 for supporting the metal frame 5U of a` detachable flexible discharge: boot 5,2. The boot 52 is secured in position for receiving material from the hopperY when the door B is in fully open position by means of clamps 54 supported onv bolts 56 carried by lugs 58 projecting from the tracks 28 as'clearly shown in Figs. 3, 4 and 5. i In the form of the invention shown in Figs. 2 to 6 inclusive, the door B is of greater length than the length'of the hopper at its dischargeY end and its projecting portion, indicated at 60 provides .a support for the door operator, the latf ter comprising a jack screw 62 threadedly engaged in a nut 64 pivotally supported by trunnions 66 in spaced brackets 68 secured to the projecting portion 6I) of the door B by means of suitable fasteners lil. The rear end portion of theV crates when the jack screw is rotated in a-direction such as to force the door Vto closed position. 'I'he reduced portion i4 .also provides a shoulder 82 adapted to engage the outer surface of lug 80 when the jack screw is rotated in a direction such as to open the door.

Figs. 7 to 9 inclusive disclose a modication of the construction just described. The door frame casting, indicated generally at F, is so formed as to be fitted around the several walls of the hoplatter having a plurality of depending bearing elements 89 inV which :axles 9| are supported, the axles extending through the rollers 93 which are mounted for shifting movement on inturned anges 95 forming parts ofthe track members 85. At the forward end portion the frame F is provided with an abutment 91 against which a jack screw 99 abuts;V the latter being threadedly engaged in a nut IUI riveted as at |03 to the proh-V jecting portion 165 of the gate G, In the instance shown in Figs. 7 `to 9 inclusive movement ofY the jack screw 99 in one direction causes an outward shifting oi the gate G because of the abutting engagement of the screw 99 with the abutment 92'. the door or gate G is not aided in its closing movement by the jack screw 99 but must be manually forced to fully closed position. Y

In the construction shown in the remainder of the figures of the drawings, with the parts in the position shown in Fig. 2, it is apparent that oper-V ation of the jack screw in one direction will cause the shoulder 82 to act against the lug 86 and eifect an outward movement of the gate or door B. When the screw has reached the limit of its movement, it is freed from its engagement with the lug V8l) by being turned in thebrackets 68 to the position shownin Fig. 6 whereupon the door may be fully openedvby being forcibly and manually shifted on its rollers` 40 until the stop 46 contacts with the tie 44. In closin'g'the door.Y B the door is manually and forcibly urged'in` wardly until the head 16 of the jack screw 62 may be engaged with the lug 80 whereuponV operation of the said jack screw in the reverse di-A rection will cause the door to be moved to fully closed position. It isapparent, therefore, that while the jack screw 62 Vis a door actuator it is also a starter, rotation thereof causing the jack screw to cooperate withrthe door frame in start-,- ing the door from closed to open position. In closing the door it is ,apparent that when the door has been shifted to a position such that the jack In the instance shown in"Fig. l

screw may be engaged with the lug 80, rotation of the jack screw will effect complete closing of the door.

From the description just above it is believed that the construction and operation of the invention will be fuily apparent to those skilled in the art without further elaboration. The drawings disclose certaihforms ofthe invention, but it is door frame secured to thehopper and formed with inwardly facing oppositely arranged tracks, a door adapted to close the discharge end of the hopper and having a portion projecting outward from the side of the hopper when the door is in closed position, rollers supporting the door and arranged in said tracks, and door actuating means supported on the projecting portion of the door and adapted to cooperate with the door frame upon operation thereof during a portion of the movement of the door in both opening and closing directions.
