SAiND-LIFTING APPARATUS.
Application filed A-pri117,'1922', Serial No. 554,380. Renewed February 1, 1924.
To all whom it may concern."
. Be it known that I, BAn'roN S. SNOW, a citizen of the United States, resid-in at. Batavia, in the county "of Kane and tate of l' Illinois, have invented anew and useful Improvement in Sand-Lifting Apparatus, of which the following is a specification.
My invention relates, more particularly,
to apparatus by which sand, and other relalo'tively finely divided material, may bevelevated to a desired point of storage, or discharge; :andmore'especially to apparatus provided for this purpose and involving the use of fluidpressure, as for example compressed air, for effecting the lifting of the material.
Apparatus of the general type above referred to as Commonly provided. involves the provision of a receptacle into which the sand to be elevated 'is discharged, this receptacle having an opening through which fluid pressure, as for example air, is introduced into the upper portion of the receptacle, with a pipe opening at its lower end into the receptacle adjacent the bottom of the latter and extending to the point of elevated discharge, the introduction of the fluid pressure into the tank serving to force the same upwardly through the pipe. The provision 30 of apparatus as stated, instead of producing a uniform upward discharge of the same through the pipe, has the effect of causing the sand to become bunched, so to speak, in the pipe, which is objectionable, particularly where the pipe is formed with portions extending at angles to each other, which is often the case and which afford surfaces which extend more or less horizontally, as the same becomes lodged on these surfaces and obstructs the passage of the sand to the point of discharge.
My primary object is to provide a novel and simple method and apparatus which will not present the objection stated, wheretion will be avoided.
Referring to the accompanying drawing:
Figure 1 is a view in elevation, partly sectional, of sand-elevating apparatus constructed in accordance with my invention, and suitable for carrying out my improved method, a portion only of the piping through which the sand is conveyed to the point of discharge being shown; and Figure 2, an enlarged section taken at the line 2 on by interruption of the sand-lifting opera-' Fig. 1 and viewed in the direction of the arrows. I I In the particularv construction shown the hopper-into which the sand, or other ma terial to be elevated, is dumped, is represented at 3, the, outlet 4- of this hopper communicating with an opening 5 in the top wall 6 of the tank 7 into which the sand, prior to elevating it, discharges, the inlet 5 being" provided with any suitable valve means such as those shown and which are in accordance withcommon practice and involve a ball 8 forming the valve proper which is carried on the lower end of a rod 9 and serves when raised to the position The top Wall of the tank 7 is shown as formed of two sections 11 and 12, the sec tion. 11 being formed at its marginal edge with an annular depending flange 13 telescoping with the cylindrical side wall of the tank 7 and connected therewith as by the rivets 14, the section 11 containing an opening 15 centrally disposed therein. The section 12 is of a diameter greater than the diameter of the opening 15 and overlaps the wall of the opening 15 throughout the extent of the latter, as shown, in which position it is secured, as by the bolts 16, an airtight joint being made between these sections. The inlet 5 and the opening through which the pipe 10 extends, as hereinbefore stated, are provided in the section 12, this section containing another opening 17 into which the upper, open, end of a pipe 18 extends and is secured, this pipe depending into the tank 7 and extending at its lower, open, end, adjacent the bottom wall 7 of the tank 7. The piping through which the sand is delivered to the elevated point of discharge, is represented generally at 19, the lower end of this piping extending into, and being secured in, the upper end of the open ing 17 in vertically spaced relation to the upper end of the pipe 18. The pipe 19 may have one or more portions angularly disposed relative to another or others thereof,
as for example as represented at 20, and so disposed that a horizontal surface, or surfaces, is presented within the course through which the sand travels, it being common in apparatus of the characterabove stated, for a number of these substantially horizontal surfaces to be presented. 7
The inner wall of the opening 17, between the pipes 18 and 19, is annularly cored to present an annular recess 21 having arestricted annular opening 22 communicating with the opening 17, the recess 21 being in communication with one end of a pipe 23, the opposite end of which opens into the main feed pipe 10, at 24, the pipe 23 being preferably provided with a hand-operated valve 25 for regulating the flow of fluid pressure from the pipe 10 into the pipe 23 and thence into the recess 21.
In the operation of the apparatus the sand to be elevated is permitted, by opening the valve 8, to charge into the tank 7 and the supplying of compressed air to the pipe 10 serves to cause compressed air to flow into the tank 7 above the sand therein and also into the recess 21, the air entering the top of the tank serving'to force sand upwardly through the pipe 18 and the air which discharges from the recess 21 into the stream of sand and air rising through the opening 17 serves to agitate the same, di-
luting it with air and producing a condition whereby the objectionable bunching of the sand hereinbefore referred to and the lodging of the sand upon any substantially horizontal portions provided in the piping '19, is avoided.
While I have'illustrated and described a particular construction of apparatus embodying my invention and have shown a particular apparatus for practicing my improved method, I do not wish to be understood as intending to limit my invention thereto as the novel features of the apparatus'may be embodied in other forms of apparatus and the method practiced by the 7 use of the apparatus. I 1
'What I claim as new, and desire to secure by Letters Patent, is:
In material-lifting apparatus, the combination of a tank for the material to be lifted, a conduit opening into said tank and through which the material is elevated, means for subjecting the'material in the tank to fluid pressure for forcing it through said conduit, and a second conduit for fluid pressure, said second conduit open- BARTON s.
