SAND-SIFTING MACHINE.
sPEGIFIGATION forming part of Letters Patent No. 723,187, dated March 17, 1903. Application filed Pebruary lt, 1902. Serial No- 93,876. (No model.)
To all whom it may concern.-
Be it known that we, JOSEPH W. SAPPING- TON, THOMAS A. KENDRICK, and CURTIS WRIGHT, J r., citizens of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented new and useful Improvements in Sand-sifting Machines, of which the following is a specification.
Our invention relates tovibrating screens for sifting sand or separating sand from gravel; and our invention is designed to be employed in connection with a certain machine for feeding sand to stone-saws, polishing-beds, &c., on which machine Letters Pat-- out were applied for March 22, 1901, Serial No. 52,350, by Thomas A. Kendrick, Joseph W. Sappington, and William N; Phillips,- of Carthage, Missouri.
The object of our invention is to prevent pebbles and dirt from access to the stonesaws or polishing-beds by screening or sifting the sand before it is delivered thereto.
In the accompanying drawings, in which corresponding numerals refer to corresponding parts, Figure 1 is an end elevation of our invention. same. Fig. 3 is a plan View of the same, omitting the water-pipe. Q
In Figs. 1 and 2 the floor is represented by a line for clearness.
1 is a hopper-shaped receptacle forming the frame on which the coarse screen 2 and the gearing described hereinafter are mounted. The screen 2 is inclined, as shown in Fig. 1, its lower side projecting past the side of the hopper 1. The frame of the screen 2 is hung by flat steel springs 3 from iron standards 4, rigidly secured to the hopper 1, either inside or outside. The lower ends of the springhangers 3 are riveted or bolted to lugs 5,which are secured to the screenframe. The screen 2 is vibrated by a pitman 6, connected to a cranked shaft 7, mounted" in bearings 8 8 and having a bevel gear-wheel 9 mounted there on, driven by abevel gear-wheel 10 on a shaft 11, on which is a belt-pulley 12. The sand that falls through screen 2 to the bottom of the hopper 1 is pushed out through an shaft 11. .witha feather 26, and its hub is grooved, as shown in Fig. 3, to receive the studs of a Fig. 2 is a side elevation of the opening 13, Fig. 1, by rotation of a screw conveyor 32, mounted on a shaft 33, on which is a pulley 34, which may be driven by a belt or by any other means desired. The sand falls on a screen 14, made of wire-cloth of fine mesh. A Water-pipe 15 is provided for discharging water upon the sand upon the screen 14 to facilitate the sifting operation. Aspraying-nozzle may be attached to the pipe 15, if desired. The water-pipe 15 is preferably connected to a waterworks-pipe, which will supplyit with water under pressure; but pipe 15 may be connected to an elevated water-tank ifno-better supply is available.
;The screen 14 is hung by spring-hangers 16 from standards 17, secured to the floor, and is vibrated by a pitman 18, connected to a cranked shaft 19in bearings 20 20, having a bevel gear wheel 21 thereon, engaged by a bevel gear -wheel 23 on vertical shaft 24, on the upper end of which is a bevel gear-wheel 25, driven by the aforesaid gear-wheel 10 on Gear-wheel 9 is splined on its shaft shipper 27 of the ordinary type.
Rigidly secured to the shipper 27 is a rod 28, which extends downwardly and then horizontally, its horizontal portion being mount- ;ed slidablyin'lugs 29 on bearing-brackets 8 8.
By-pushing or pulling on rod 28 the splined gear-wheel 9 may be thrown into or out of gear with gear-wheel 10. The pulley-shaft ll'may be driven continuously; but the screen 2 need be used only when the hopper 1 is being. replenished with sand. When the sand is all sifted,the motion of screen 2 is stopped by throwing gear-wheal 9 away from gearwheel 10 by rod 28, as aforesaid.
When the sand reaches the fine-screen 14, the sifting is aided by the water discharged frompipe 15. The sifted sand falls into a spent 31, from which it is conducted to the point where it is to be used. 7 y 7 Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-
The combination, with a hopper having an outlet-opening therein, of a vibratory screen thereabove, a horizontal shaft, means for vibrating said screen by rotation of said shaft, a gear-Wheel splined on said shaft, a horizontal drive-shaft, a gear-Wheel 10 thereon, engaging said splined gear-wheel, a vibratory screen 14 below said outlet-opening, a horizontal shaft 19, means for vibrating said screen 14 by rotation of shaft 19, a gear-wheel 21 on shaft 19, a gear-wheel on said vertical shaft, engaging gear-wheel 21, and an upper gear-wheel on said vertical shaft, engaged by gear-wheel 10, whereby said screens may be actuated simultaneously, and means for moving said splined gear into and out of mesh with gear-Wheel 10, whereby said screen 14 :5 may be actuated alone; substantially as described.
In testimony whereof we affix our signatures in the presence of two Witnesses.
