RAYMOND W. DULL, OF AURORA, ILLINOIS.

SEPARATOR.

To all whom it may concem:

Be it known that I, RAYMOND W. DULL, a citizen of the United States of America, and resident of Aurora, Kane county, Illinois, have invented a certain new and useful Improvement in Se arators, of which the following is a speci cation.

My invention relates to separators of that particular class in which a movable receptacle is provided for receiving the materials of different specific gravity, such as sand and water, and which is mounted to move when the load increases beyond a certain point, said movement being utilized for discharging the sand or sediment at the bottom of the receptacle, and the water being allowed to overflow at the top of the receptacle.

Generally stated, the object of my invention is to provide a novel and highly eflicient separator of the foregoing general character.

The special object is to provide a novel construction and arrangement whereby a stationary valve member may be used for the receptacle, to control the discharge of the sand or other materials from the bottom thereof, and whereby acomparatively small or light counterbalance may be employed for 'yieldingly holding the receptacle in normal position, thus permitting the entire area or capacity of the receptacle to be utilized for holding the water and sand or other ma-' terials constituting the load.

It is also an object to provide certain details and novel features of construction tend- -ing to increase the general efficiency of a separator of this particular character.

To'these and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings Figure l is a side elevation of a separator embodying the principles of my invention. Fig. 2 is a front elevation of the said separator showing one of the counterbalance and valve arrangements removed for convenience of illustration and to bring into view the discharge opening controlled by the valve.

As thus illustrated, my invention comprises a receptacle A provided with vertical and parallel sides a and a vertical front wall a The bottom a of the said receptacle Specification of Letters Patent.

Application filed May 11, 1912.

Patented June 16, 1914. Serial No. 696,572.

is inclined downward from the top of the receptacle to a point below the discharge openings a which latter are located in the lower portion of the said front wall. The sald receptacle is adapted to oscillate about an axis provided by the trunnions B which have knife edges which rest in blocks or bearings Z) on the parallel supports of 6 At the upper edge of the front wall a a discharge spout a is provided for the overflow of the water.

The valve mechanism for controlling the discharge openings a comprises a stationary support C provided with stationary valve members which normally close the said openings, the vertical surface of each member 0 engaging the opening to form a tight joint. The counterbalance lever D is provided with a fulcrum cl which is supported by a track al mounted on the support C, whereby the said lever D swings about a stationary axis. The shorter or inner end of the said lever D is pivotally connected with a link 6?, which latter is in turn pivotally connected with a bracket d on the front wall of the receptacle. A weight (Z is mounted to slide back and forth upon the lever D and is provided with a set screw (Z for holding it in adjusted position thereon. Preferably, there is a counterbalance of this character for each valve, whereby each discharge opening a is closed tightly when the receptacle is in normal position.

When the water and sand are discharged into the top of the receptacle A, by any suitable means, the sand sinks to the bottom and accumulates until the weight thereof, plus the weight of the water, is suflicient to cause the receptacle to oscillate about its axis, and at such time the water overflows by way of the spout a The oscillation of the receptacle in this manner produces an opening of the valvesthat is to say, thelower end of the receptacle moves away from the stationary valve members 0, whereby the openings a are uncovered to discharge the accumulations of sand or other relatively heavy materials. In order to oscillate, however, the receptacle must raise the counterbalance D, and the operation is regulated by the adjustment of the Weight (1*, whereby the mechanism can be set to discharge at the proper time, or in such manner that a load of either more or less weight will be required to oscillate the receptacle. ()rdinarily, however, the said weight J is so adjusted that the receptacle must be filled until it carries the load at each side of the axis provided by the trunnions B, it being observed that this axis is located at a point between the front and rear ends of the said receptacle, and in such manner that a considerable load will accumulate at the rear of this axis before the receptacle will oscillate. It follows, therefore, that while the load is accunnilating and rising in the receptacle, and before it reaches such a height as to extend at both sides of the axis, the weight thereof will be exerted altogether and entirely in. a direction tending to raise the counterbalance. Later on, however, and as the receptacle continues to fill, a considerable load will accumulate at the other side of the axis about which the receptacle tilts, and the weight of the load at this side will be exerted in a direction tending to counter act the weightof the load in the front part of the receptacle. To this way the filling of the receptacle, and the increasing of the load, may continue much longer than would be the case were the axis of the receptacle so located as not .to divide the load into two portions, and consequently a smaller or lighter counterbalance can be employed. In other words, and with the arrangement hown, involving the location of the axis of ti e receptacle at a point which divides the load into two portions, the receptacle does not oscillate and discharge the sand as quickly as would be the case were the load carried at one side of the said axis. This, stated, permits the use of a smaller or lighter counterbalance and enables the receptacle to accumulate a substantial load before dischargingthe sand or other materials from the bottom thereof.

lZVhat I claim as my invention is:

1. A separator comprising a movable receptaole provided with a vertical wall hav inga lower discharge opening, a stationary member having a vertical surface for en gaging the rim of said opening and normally closing said opening, a counterbalance for maintaining the normal position of said receptacle, a fulcrum for said counterbalance, and a connection between said counterbalance andsaid front wall, disposed immediately above said opening and surface, said surface serving as. a stop to limit the clos ing motion of the receptacle.

2. A separator comprising a movable receptacle provided with a vertical wall having a lower discharge opening, a stationary gmembor having a vertical surface for engaging the (rim of said opening and normally closing-said opening, a counterbalance for maintaining the normal position of said reconta ts; a fulcrum for said counterbalance,

and a connection between said eounterbalance and said front wall, said fulcrum being supported by said member, said surface serving as a stop to limit the closing motion of the receptacle.

3. A separator comprising a movable re ceptacle provided with a vertical wall having a lower discharge opening, a stationary member having a vertical surface for engaging the rim of said opening and normally closing said opening, a counterbalance for maintaining the normal position of said receptacle, a fulcrum for said counterbalance, and a. connection between said counterbalance and said front wall, said connection comprising a link having one end pivoted on the said receptacle, and the other end pivoted on the shorter arm of said counterbalance, said surface serving as a stop to limit the closing motion of the receptacle.

4:. A separator comprising a movable receptacle provided with a vertical wall having a lower discharge opening, a. stationary member having a vertical surface for engaging the rim of said opening and normally closing said opening, a counterbalance for maintaining the normal position of said rcceptacle, a fulcrum for said counterbalance, and a connection between said counterbalance and said front Wall, said receptacle having an inclined bottom sloping downward from the top of the receptacle to the said opening, and an axis for said receptacle, disposed at a point requiring a load at each side thereof to raise said counterbalance, said surface serving as a stop to limit the closing motion of the receptacle.

5. A separator comprising a movable receptacle provided with a vertical wall hav ing a lower discharge opening, a stationary member having a vertical surface for engaging the rim of said opening and normally closing said opening, a counterbalance for maintaining the normal position of said receptacle, a fulcrum for said counterbalance, and a connection between said counterbalance and said front wall, and a stationary support for said fulcrum, said surface serving as a stop to limit the closing motion of the receptacle.

6. A separator comprising a movable receptacle provided with a vertical wall having a lower discharge opening, a stationary member having a vertical surface for engaging the rim of said opening and normally closing said opening, a counterbalance for maintaining the normal position of said receptacle, a fulcrum for said counterbalance, and a connection between said counterbalance and said front wall, and a stationary axis of oscillatory movement for said receptacle, said surface serving as a stop to limit the closing motion of the receptacle.

7. A separator comprising a nrovable receptacle provided with a vertical wall havserving as a stop to limit the closing motion 10 of the receptacle.
