GATE VALVE FOR SAND AND GBAVEL DUMPS.

Application filed August 2, 1921.

To all whom it may concern:

Be it known that 1, WILLIAM M. humans, a citizen of the United States, residing at Reno in the county of Washoe and State of Nevada, have invented a new and Improved Gate Valve for Sand and Gravel Dumps, of which the following is a specification.

This invention has reference to an improved means for regulating the outflow from sand and gravel dumps, ore piles, and the like, and it has for its purpose to provide a means of the general character stated oi a comparatively inexpensive constru tion. that is more especially designed for regulating the quantity oi sand or gravel, either in the wet or dry condition, which gravitates from the dump onto conveyers for delivering the material at some desired place.

Generically, my invention comprehends an improved arrangement 0? a dump retaining wall having an outlet for the passage of the material as it gravitates from the dump, a receiving trough or conduit from which the material, as its drops into the receiving trough or conduit, is carried by an endless conveyor and elevated to a place for use or for loading into cars or wagons for being conveyed to the place of use.

My invention also comprehends a peculiarly arranged outlet or passage through which the material in its escape from the dump in position for being gathered by an Lip-carrying conveyer and a control or gate valve for the said outlet or passage whereby the dropping oil? the material, as it gravitates through the retaining wall outlet is regulated to fiow rapidly or slowly, as conditions for moving the out passing material may make necessary.

lVith these and other objects in view, as will hereinafter be apparent, my invention comprises certain features of construction and novel arrangement of parts, all of which will be explained in the "following detailed description, specifically stated in the appended claims, and illustrated in the accompanying drawings, in Which Figure 1 is an end elevation of a portion of the dump retaining wall having the out let, the gathering chamber that receives the material which gravitates through the out let, and the adjustable gate device.

Serial No. 189,336.

Figure 2 is a longitudinal section of a port on of a sand and gravel dump, the retaining wall having the outlet, and the gate valve device that controls the droppin of the material into the convevcr reccivin conduit or trough, V b

Figure is a detail horizontal s ction on the line 3-3 of Figure 2.

Figure 4 is a perspective view of one form of the gate valve shitting lever used. in connection with my peculiarly arranged gate valve devices. I i

In the drawings, which illustrate a pract cal arrangen'ient of my invention, a portion of a sand and gravel dump 1 is shown in Figure 2, which may be an ordinarv ground surface incline, but is preferably provided with a solid or concrete surface for facilitating the travel of the sand and gravel toward a retaining wall 3 which, in practice, is built up of heavy wooden tinibers suitably braced and which, along the upper base line of the dump, has an outlet 4-, preferably square, as shown in dotted lines on Figure 1.

By referring to Figures 1 and 3 of? the drawings, it will be noticed a material receiving compartment 5 is formed ust outside the passage 4: in the wall 3 and the saithcompartment is shaped by a metal housing 6 which includes a face wall in parallelism with the wall 3, and an end or angled wall "which has a lateral. flange 61 whereby to secure the said end of tlie housing (by screws '7) to the retainingwall 3, the other end of the housing being liXedlv secured by large screws 8 that take into the uprights or framing timbers 9 and which constitute a part of the wall 3.

The top and the bottom of the chamber 5 may be open, as shown. and the opening in the bottom, which is located ust abovh the receiving trough or conduit into which the outflow of the material is fed, is controlled by a gate valve 10 of metal whose opposite edges rise in guide grooves 11 formed, at the inner edge, by a cleat 12 attached to the outside of the wall 3 just below the bottom opening l and a cross plate 13 se cured to the bottom edge board. the said plate 13 constituting the bottom face of the opening 4t. The guide for the outer edge of the valve 10 is "formed by a metal cross member 15 whose opposite ends are screwed onto the uprights 1616, and an angled strip 17 which is bolted to the members 16, as shown.

The valve plate 10 is of a length to extend some distance beyond the end of the housing 6 and the it'ree end thereof has a pair of apertures 10 10 near the outer edge, the purpose of which will presently appear.

7 2O designates a cross bar which extends horizontally over the housing 6 from one end upright to the other of the framing, and at a point midway the end 6 of the housing and the adjacent upright or post an elongat ed U shaped bearing 25 is projected inwardly from the cross member 20, which member is located near the upper end of the housing 6, as shown.

30 designates a long lever having a bifurcated lower end 31, a handle 82 at the upper end and for clearance, when using, the saidlever is bent midway its length, as best shown in Figure 4E.

The lever 30, when the parts are operatively assembled, fits between the loop bearing 25 with its forks 31 in engagement with the apertures 10-10 in the adjacent end of the gate valve 10, it being obvious by referring to Figure 1, that the limits of adjustment of the gate to the open and-closed positions are indicated by the full and dotted lines position of the lever. I

In the drawing, the lower end of an upgoing endless scoop chain conveyer 18 is shown, which is arranged to take up the material through the bottom of the chamher 5. Under some conditions, the endless conveyer is not necessary since the material, as it gathers in the conduit, can be readily removed by shoveling it into wheel barrows or wagons loaded adjacent to the sides of the conduit.

From the foregoing description, taken in connection with the drawings, the construction, the manner of use and the advantages of my invention will be readily understood by those familiar with the operation of mloading sand and gravel dumps.

Owing to the peculiar arrangement of the receiving chamber 5 and the adjustable gate valve 10 in the bottom thereof, simple and easily manipulated provision is made for regulating the passage from the said receiving chamber into which the material flows from the outlet 4. j

The discharge passage from the receiving chamber 5 being always smaller than the outlet 4 in the retaining wall 3, the said smaller passage is readily increased or diminished by means of the lever 30 to suit the condition of the material being worked, whether wet, dry or partly wet and dry,and which flows through the aforesaid outlet 4.

What I claim is I 1. In an ofiitake for sand and gravel dumps and the like, the combination with a retaining wall along the bottom of the dump, the said wall having an outlet at the bottom of the dump through which the material from the dump is discharged by gravity; of a housing that constitutesa chamber into which the material as it gravitates through the retaining wall outlet is received, a gathering conduit below the receiving chamber, the said chamber having a 'discharging opening in the bottom thereof through which the material passes into the conduit, the said opening being of less area than the opening in the retaining wall.

2. As an improvement in means for loading material from Send and gravel dumps, the combination with a retaining wall against which the material on the dump constantly gravi'tates, the said wall having an opening oi fixed size through whichthe material continuously flows, a chamber on the outside of the wall into which the material flowing through the wall outlet is received, the said chamber having a valve gate controlled bottom discharge, a conduit below the valve bottom discharge of the receiver into which the material passing from the dump is collected and from which it is conveyed, the said valve moving in a horizontal plane over the bottom opening of the receiving chamber and having one end extended beyond the said chamber, the chamher being formed by a housing including an angled end secured to the. retaining wall and whose other end is secured to abeamj attached to the outside of the wall, a brace iember that extends across the housing and is attached at its opposite ends to upright timbers that constitute a part of the wall, an elongated U shaped bearing that projects inwardly from the, said brace member, the exposed end of the gate valve having a pair of apertures, and a lever adapted for being removably. fulcrumed in the U shaped bearing and provided with a forked lower end for engaging theapertures in the gate valve,
