Dorey, Westmount, Quebec, Canada, assignor to Enterprise Railway Equipment Company, Chicago, Ill., a corporation of Illinois Application December 24, 1948, Serial No. 67,215

My invention relates, generally, to the convide an assembly including a discharge outlet frame and a co-operating sliding closure having auxiliary sealing means around the edges thereof.

Another object of my invention is to provide a frame and closure assembly in which auxiliary sealing .means are employed to supplement the sealing security normally provided by the weight of the closure and lading resting upon runways.

Still another object of the invention is to provide improved, simple and effective means for retaining a sliding closure in a definitely closed position.

My invention further resides in certain other details of construction such as will-be pointed out hereinafter.

For further comprehension of my invention reference may be had to the accompanying draw-, ings wherein:

In said drawings my improvements are shown as applied to an outlet assemblyofthe conven tional type including a frame A, a sliding closure or gate B having a series of rack teeth H) on the underside thereof, and shaft and pinion means C co-operablewith the said teeth [0 for moving the gate lengthwise. The frame A includes an upper attaching portion including side. sloping Walls H-H and end sloping walls [2 and til, the latter being slotted at M for accom modating the Sliding closure. therethrough. The end sloping wall I2 and the side sloping walls H--l I lead downwardly to substantially vertical wall sections l5 and 16-46, the latter being disposed in substantially parallel relation and operating as guides between which the edges of the side walls of the closure B are guided andthe movement of theclosure restricted to a rec-; tilinear movement.

Extending inwardly from the said walls I5 and 16-46, as shownin Figure 3, are substantially horizontally disposed side and end runways as indicated at 11 and [8 respectively on which the closure B is arranged to have sliding at 23. The wall2 I, which is located at-the outer end of the outlet, includes a horizontal ledge.

: in the form of an upper wall 24, a downwardly inclined section 25 and a vertically disposed lowersection26. t;

The walls l9;l9 are disposed slightly out of parallelism diverging outwardly towards. the slotted-end of the outlet whereby said respective walls l9 l9 in combination with the end walls 20 and 2| present a substantially. wedge shaped four sided dischargeopening; The lower portion of :the frame A is provided with outwardly laterally extending portions. includin a flange 2 1 on two adjacent sides and a horizon tally disposed groove 28 on the twootlier adja- 3 cent sides, said flange and groove being for the purpose of receiving and holding a removable spout structure for directing lading away from the outlet frame.

The sliding closure B which is mounted for movement on the runway surfaces I1 and I8 is extended beyond the longitudinally extending side runways I! of the frame-and through the slot I4. The upper wall of the slot I4 slopes upwardly and outwardly as at 29, Fig. 2, to provide a Wedge shaped flared mouth for the slot l4.

The outer end of the closure B is provided with a groove 30, Fig. 9, extending throughout its entire Width to form, in combination with vertical Wall 3 I a pocket for receiving a resilient deformable gasket 32, which is bolted or otherwise-secured to the gate at 33. Said gasket is arranged to jam in the flared mouth of the slot 14 when the closure is forced home and thus effectively to seal the opening through the frame A at the outer-edge thereof. H

The closure B is stepped, Fig. 7, to provide a main upper section 34 resting on the runways l1 and I3 and a lower section 35 inset in the frame or chute A. The inset portion 35 corresponds in shape to the interior wedgeshaped contour presented by walls [9 and 20 of the frame A and includes side and end. depending walls 36 and 31, Fig. 5, and outwardly of immediately adjacent said Walls. 36' and 3'! the upper main section 34 is formed with grooves 38. Said walls 36 and 3'! of the gate. are spaced away from the interior face of the walls of the frame A to accommodate tubular shaped gaskets 39 and 49 which are preferably bolted to the associated walls 36 and 3'! as indi cated at 4|. The walls 3636 diverge outwardly towards the slot M in the frame A-so that they are parallel to the walls i9l 9 respectively and provide a Wedge shaped section on the closure B.

The respective gaskets 39 and 40 preferably meet in mitered relation and combine toform a wedge shaped resilient deformable binding around three sides of the lower inset section 35-of the closure. The outer ends of the side gaskets 39 are extended to intersect and have bearing contact with the end gasket 32. I

The extent of divergence of the side gaskets 39 is indicated at 42,'Fig. 5.' The wedging structure on the closure or gate B, as presented by the outer surfaces of the expanded gaskets 39 and 40, is slightly larger than the interior contour of the opening through the frame A in order to ensure deformation of the'gaskets 39 when'theclosure or gate B is forced home to fully closed'position and thus provide a tight seal between the lower inset section 35 and the walls 19 and 29 of the frame A.

In order tosupport the closure or gate'B in open position, the closure structure A is fitted with extension rails 43, Figs. 1 and 2, which are secured to brackets 44 formed integrally with the frames The railsv 43 are provided with upward extensions, the edge portions 45 of which formabutments for co-operation with a locking element 46. The locking element 46, which is pivotally mounted on the closure at 41, extends from side to side of the closure and isprovided at each end with an operating 4 lug 48." This locking mechanism is claimed in divisional'application Serial No. 310,203, filed September 18, 1952.

The means for moving the closure longitudinally includes the rack teeth II] in co-operation with the shaft and pinion means C. The pinion which is indicated at 49, is non-rotatablymounted on the shaft 53 and the latter is preferably of rectangular shape and fitted with bushings 51 whereby it is rotatably mounted in bearings 52 of the frame A. Any suitable handle may be employed for rotating the shaft 50.

The rack teeth [0 are disposed centrally of the closure and each alternate tooth is extended across the closure B as indicated at 53, Fig. 5, to unite integrally with the depending side walls 36. of the inset section 35.

The function of the gaskets, 32, 39 and 49 as wil1 be understood, is to provide sealing security in addition to that normally provided by such sealing contact that is obtained by the weight of the closure B and lading resting upon the runways i'l.

Upon movement of the closure B in a closing direction, the side gaskets 33 impinge on the divergently disposed side walls l9 of the chute and they are compressed, thus ensuring tightly fitting seals. Movement of the closure B being con tinued in a closing direction operates to compress gasket-49 against the end Wall 29 of the frame A and also operates to jam the front gasket 32- in the wedged shaped opening to the slot i4.

Deformation of the gasket 32 within the confining limits of slot l4 reacts upon the longitudinally disposed gaskets 39 in view of the intersecting contact between said respective members and thus operates effectively to seal the outer end of the outlet.

At the junction of the end and side walls I9 and 29 there is a tendency to fullness in the amount of gasket material displaced due to variations in the size of the fillets 54 Fig. 3. In order to ensure that such displacement will not react upwardly against the closure, a recessed chamber 55, Fig. 5, is provided in the upper section of the closure A directly above. each mitered joint between the gaskets 39 and 49.

It will be understood that the resilient nature of the gaskets 32, 39 and 40 will tend to move the closure B outwardly in an opening direction. Therefore I provide the locking and wedging means in the form of the pivoted locking element 46 to exert direct longitudinal pressure on the closure B for the purpose of lockin the same closed.

The gaskets 32, 39 and 40 are so located on the closure or gate B as to be readily accessible for inspection and renewal. My invention, as disclosed herein, further renders the possible interchange of closures from one frame to another. This eliminates the necessity for close machining andfitting of the parts entering into each individual assembly.

Since the gaskets 32, 39 and 40 are formed of resilient material, they act to absorb shock between the closure or gate B and the frame A. This ensures that the sealing engagement therebetween will be maintained and the escape of lading, even when finely divided, will be prevented.
