range of movement between open and closed posiv t tions; to prevent upward movement of the gate without providing stops therefor above its surface; to fashion the frame so that the runways or guides for the gate can be machined without interference by a side wall of the frame; to fashion the frame with the portion of the side wall above the slot through which the gate moves omitted and later supplying this Wall portion as a separate item and securing it in position after the runways or guides have been machined; and to construct the frame with a view to casting it without using large molds or complex cores.

Other objects of this invention will, in part, be obvious and in part appear hereinafter.

This invention is disclosed in the embodiment thereof shown in the accompanying drawings and it comprises the features of construction, combination of elements and arrangement of, parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims.

For a more complete understanding of the nature and scope of this invention, reference can be had to the following detailed description, taken together with the accompanying drawings, in which:

Referring now particularly to Figures 1, 2 and 3 of the drawings, it will be observed that the reference character I0 designates, generally, a rectangular cast iron frame which has an upper vertical side wall II and outared or inclined The walls II, I2 and I3 extend over a suitably shaped car hopper I4 which is indicated by broken lines in Figure 3. The walls II, I2 and I3 are cast integrally with the frame Ill along three of its sides.

The wall along the fourth side opposite the end wall I2 is not formed integrally with the other walls and with the frame I 0 in order to facilitate machinery of certain runway or guide surfaces which will be described presently.

As illustrated in Figures 3 and 5, the frame I0 also comprises a vertical lower side wall IVI, vertical lower end and side walls I8 and I9, and an inclined lower end wall 20, it will be understood that these walls Il', I8, i9, and 20 are cast integrally with the frame I0. The lower side walls I'l and I9 have angular rearwardly extending portions 2l and 23 whichare provided with upper anges 25 and 2l, respectively, to form a generally T-shape as shown more clearly in Figure 4. The upper surfaces of the flanges 25 and 2l are machined to provderunway or guide surfaces 29 on which a generally rectangular cast iron gate, shown generally at 30 in Figure 7, is arranged to slide. The gate 30 has under surfaces 3l along its edges which are machined so as to slide readily along the runway or guide surfaces 29 on the upper sides of the upper flanges 25 and 2l as will be understood readily. These machined surfaces 29 and 3l also serve by their intimate and complete contact to seal the sides of the discharge `outlet so as to prevent the flow of finely divided lading therepast.`

As shown in Figure 5, the upper surface 32 of the vertical lower end Wall I8 is machined for interiitting with an under surface 33, Figure 7, along the forward edge of the gate 30 when it is in the closed position. This construction also prevents the discharge of lading along the forward edge of the gate 30 when it is closed.

An important feature of the present invention is the means for holding the gate 30 in the closed position in the frame I0. For this purpose guide plates 34, Figure 7, are provided along the under l surface of the gate 3D at its sides. They are spaced from the gate 30 by bosses 35, Figure 4,

and flanges 36 which are cast integrally with the gate 30. 'Rivets 31, or other suitable holding;

means, extend through the bosses 39 and the guide plates 34 to hold the latter in position along the under side of the gate 30,. lIntegrallyl,farmed with the plates 34 are extensions 38 which, as shown more clearly in Figure 4, underlie the upper flanges 25 and 2l of the side walls il' and I9. The extensions 33 are spaced slightly from the undersides of the iianges 25 and 2i so as to permit the gate 30 to be moved freely into and out of the closed position. The under surfaces t! along the sides of the gate 3i? and the upper surfaces of the extensions 33 together deiine U- shaped slots 39 that cooperate with the flanges 25 and 2l which project into them.

As illustrated in Figure 5, the inclined lower end wall 2i) has a horizontalportion iii along its upper edge which is depressed at its ends as indicated at lil, Figure 4, to accommodate the guide plates 34. The upper surface of this horizontal portion Lit denes the lower edge of a nar row rectangular opening Il? through which the gate 30 is slidable to and from the closed position as shown in Figure. 5. The upper side or this rectangular opening i? is defined hy the lower edge d3 of one leg it oi' an angle :l5 which forms the rear upper side wall for the frame it. The angle i5 includes another leg et which extends at right angles to the leg fie.

Another important feature oi this invention is the ashioning of the frame it so as to receive the angle A5. Since the space between the upper side walls ii and i3 is open, it is possible to machine the runway or guide surfaces 29 along the upper sides. of the anges 25 and 2l without having to take into account a transversely extending wall. such as would be the case if the rear wall which is formed by the angle l5 were cast integrally with. the frame iii. It will he understood that the angle 45 may he welded in place. As shown in Figure l it may loe welded as indicated at il to the vertical upper side Wall H. Provision cank be niade for welding its other end as indicated at it to the side wall I3.

With a. view to sealing the juncture between the gate 3l) and the leg lil of the angle liti, a rib t9, Figure 6, is cast. integrally with the gate 3i! and, as here shown, it. is arranged to abuty the rea?.` side of the lower portion of the leg lill. manner and the manner described hereinbeforer a tight seal is provided around the. edges of the gate 3.5i in the frame i when the fern-ier is in the closed pcsitiom Any suitable means can ce provided for moving the gate 3@ to and from the closed position. As shown in Figure 'l a rack, indicated generallyv at 52, may be provided.. The rack 52, coinprisesteeth 53 which may be cast integrally with the gate 3o, Alternate` teeth 54 extend substantially lto the. edges of the gate 3G in order to reinforce ther same. As shown in. Figure G a pinion 55 coop.-4 erates with the teeth o3 of the rack t2.. The pinion 55 maybe fast on a shaft 5t which extends transversely of; the, frame [ii and through the angular rearwardly extending portions 2t and. 23 of the. Side Walls ii and i3. Any suitable means, not shownl may be provided for rotating the shaft 58 as will he understood.

It is; desirable. to lock the gate t in the closedposition. For this purpose culbcus sections are: formed integrally therewith along its rear edge asillustrated in Figures 6 and 7 of the draw-- ings. A. swinging locking cam, shown general-ly at 5.3,. has. arms do, Figure l, which intern-t. with the bulbous, sections 5lv and are rockably mounted thereon by ashait 6i?. The cam 38 has a curved outer surfaceV il which, in the locking posi-- tion, bears against; stops EZ which maybe cast. integrally with. the: portions 2l. and 23 of' thel frame- In this I 0. The end portions S3 of the cam 58 are shorter than the central portion Gt so as to permit the latter to project downwardly between the anges 25 and 2'! as shown more clearly in Figures 3 and 6 of the drawings.

In order to unlock the gate 3@ the cam 53 is swung in a clockwise direction as viewed in Figure 3 out of engagement with the stops B2. Thereafter the shaft 5t? can be rotated to rotate the pinion 55 and withdraw the gate 3i) from the opening deined oy the walls oi the frame it. When the gate Sti is closed, the end portions t3 of the cani t8 ride up the inclined surfaces E5, Figure 3, of the stops When the gate 3@ has been moved to the fully closed position, the cani 5t drops by gravity into the locked position against the stops E2.

Chute receiving members el, GS, Ci@ and lil may be secured by rivets 'il to the walls il, i2, I3 and 26 respectively. The member @'i is generally hook-shaped while the members t and it are in.-

the form ci angles. The roernher "it also is of hook-shape. provision of these chute receiving members forms no part of the present invention.

It will. be understood that the car hopper I4 has four sides forming a discharge opening and that the upper side and end walls li, l2 and I3,

which are cast integrally with the frame it, are arranged to interiit with 'three of the tour sides- The leg :til of the angle $5 in- 30 is provided between the lower edge oi lthe leg t6 of the angle d5 and the juxtaposed portions of the hulhous sections di of the gate and the coextensive arcuatesurfaces ci the arins 53. It will he noted that these surfaces are concentric arcuate shaped surfaces on a common radius extending frorn the shaft G@ and that they engage the lower edge of' the leg it along its entire lengthwhen the gate Eil is closed, thereby closing oi the spacel therebelow.

Preferably the shaft 56 is journaled in bearing pads i2., Figures 3 and 4, which are cast integrally with the frame i@ outside of the extensions 2i' and 23 of the side walls il' and i9 and between the Vertical planes containing the outer sides of the vertical side wall portions i'io and #3a.

Since certain changes can he made in the foregoing construction anol different embodiments of the invention can be without departing from the spirit and scope thereof, it is intended that all matter shown in the accompanying drawings and described hereinbeiore shall be interpreted as illustrative and not ina limiting sense.
