1 Claim.

The present invention relates to new and useful improvements in feeders foruse primarily for the feeding of processed clays and muds into the drilling mud used in oil and gas wells, although it will be understood that the device may be used for any other purpose for which it may be found adapted and desirable.

The primary object of the invention is to provide, in a manner as hereinafter set forth, a feeder of the aforementioned character which is adapted to be vibrated whereby a steady, uniform flow of the material will be had.

Other objects of the invention are to provide a feeder of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of a material feeder constructed in accordance with the present invention.

Figure 2 is a top plan view of the device.

Figure 3 is an end elevational view.

Figure 4 is a view in vertical section through the lower portion of the hopper.

Figure 5 is a view in horizontal section, taken substantially on the line 55 of Figure 4.

Figure 6 is a fragmentary view in perspective, showing the loose connection of the agitator to the frame.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a metallic stand which is designated generally by reference character I. The stand I includes a pair of spaced supporting legs 2 between which braces 3 extend. The stand I further includes an elongated, substantially horizontal frame 4 comprising a pair of spaced, parallel side bars 5 having one end pivotally secured at 6 to the upper end portions of the legs 2 for vertical swinging movement. Spaced cross members I extend between the side bars 5 of the frame 4.

Mounted in the frame 4 is a hopper B for the reception of the material to be fed, said hopper including, on its lower end, a, discharge neck 9. A hand adjusted gate valve l0 controls the neck 9.

As illustrated to advantage in Figure 6 of the drawing, one of the cross members 1 of the frame 4 has formed therein an opening I l which loose- 1y accommodates one end portion of an agitator rod I2. The agitator I2 passes through a live rubber bushing I3 into the lower portion of the hopper 8 and terminates in a downturned end portion which is operable in the discharge neck 9 and which extends to a point closely adjacent the gate valve If].

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, the free end of the frame 4 is connected to any suitable vibrating means. The material to be fed is placed in the hopper 8 and the valve I0 is adjusted. As the device is vibrated, the frame 4 pivots at 6 on the legs I and the material in the hopper 8 is discharged by gravity through the neck 9 and the valve l0. Shaking of the device in the above-described manner causes the lower end portion of the agitator l2 to vibrate in the neck 9, thereby positively preventing clogging and insuring a steady, uniform feed of the material. As hereinbefore stated, the upper end portion of the agitator l2 is loose in the opening ll, whereby limited universal swinging movement of said agitator in its resilient mOunting I3 will be had.

It is believed that the many advantages of a material feeder constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A material feeder of the character described comprising a substantially horizontal supporting structure pivoted at one end to be swung about a horizontal axis whereby said structure may be shaken up and down, a material receiving hopper on said structure depending therefrom with a bottom discharge neck and rigidly connected to said structure, whereby said hopperis adapted to be shaken up and down with said structure, a resilient bushing mounted in one side wall of said hopper, an agitating rod having an upper end loosely connected to said structure and a lower right angled end extending through said bushing into said hopper and down into said neck, said bushing forming a cushion support for said rod whereby, when said hopper is shaken up and,

down, said rod will be vibrated independently of up and down movement of said hopper to cause said lower end thereof to agitate material in said discharge neck and thereby prevent clogging of said neck.
