SAND SEPARATING AND WASHING MACHINE.
IPZGIEICATIQII forming part of Letters Patent No. 324,158, dated August 11, 1885.
Application filed April 25, 1855. (No model.)
To all whom it may concern:
Be it known that I, PHILIP M. PFEIL, re-
siding at Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discov thereto a dredging-machine and my improved sand washer and separator. showing the sand-washer in end elevation and Fig. 2 is a view 5 is a top plan view of my improved separating and sand-washing apparatus.
My invention relates to certainimprovements in machines for screening and washing sand, the object of said invention being to so construct and combine the revolving screen and the washing-pan that water may flow freely in and out of the washing-pan for the removal of dirt and other deleterious substances, and at the same time prevent the escape of the washed sand; and to these ends my invention consists in the construction and combinations of parts, all as more fully hereinafter described and claimed.
Between posts or stanchions, only one being shown at 1, secured near the guards of the hull A of a steamer, is pivoted the boom or frame 2, provided at its ends with suitable wheels or pulleys, over which passes the endless chain 3, provided with suitable buckets, 4. To the outer or free end of the boom is connected the chain 5, passing over the drum 6, by therevolution of which the free end of the boom is raised or lowered to the proper depth to permit of the buckets being filled with sand as they are drawn along by the movement of the endless chain. These buckets discharge the sand as they pass over the upper wheel or pulley of the boom onto a flat inclined screen or riddle (not shown) forming the bottom of the chute 7, (see Fig. 1,).said riddle serving to separate the sand from coarse gravel and stones. The sand passes from the chute 7 into the chute 8, and thence into the revolving screen or riddle 9.
The riddle or screen 9 consists of a cylindrical shell formed of interwoven wires attached at its ends to the bands or rims 10 and supported by the 'radial arms 11, extending from the hubs 12 on the shaft 13. This shaft 13 is mounted in journals 14, secured to the cross-braces 15, connecting the guardrail and the hull of the boat, said cross-braces being so arranged that the shaft 13 and screen 9 will be slightly inclined to the surface of the water, as clearly shown in several views. On the pcripheries of the rims 10 are formed the outwardly-projecting flanges 16, between which are located the wings 17, the purpose of which will be hereinafter stated. Below the revolving screen 9, and partially surrounding its lower portion, is placed the pan 18, secured along its sides to the guard-rail and the hull of the boat, respectively. The ends of this pan 18 are bent up, forming flanges 19, which in turn are bent inwardly, as shown, forming the overhanging ledges 20, which GXlLOTld'lJO or nearly to the flanges 16 on the screen 9. These flanges 19 and ledges 20 form, in connection with the flanges 16, a joint through which water may escape from the pan, but which will prevent the washing away of the sand with the escaping water. The shaft is provided with a bevelgear, 21, adapted to mesh with the corresponding pinion, 22, on the shaft 23, which is driven by any suitable means in the boat. It will be noticed that the higher end of the screen 9 is toward the bow of the boat, and that the sand and other materials are discharged into said end, and in the use of the apparatus the boat should be so trimmed that the lower portion of the screen, for about three-fourths of its entire length, should be immersed in the water; but it may be submerged to a greater or less degree, if desired. constructed and arranged with reference to the screen that when the latter is immersed, as above stated, the lower portion of the pan will be almost entirely immersed, as clearly shown in Fig. 3.
As the sand, &c., is discharged into the The pan 18 is so 1 upper end. of the revolving screen from the chute S, the sand is separated from gravid and other foreign material, and passes through the meshes of the screen into the pan 18, where the washing away of mud and other impurities, which is principally effected in the screen, is completed, the sand and water being agitated together in the pan by the wings 117 on the screen, said wings also serving to sweep the sand as it collects in the pan over into the sand-box 2 t, located within the hull A, in con veuient proximity to the screen i) and pan. The flanges 16 on the rims and the ilanges 119 and their overhanging ledges 20 prevent a direct Jlow of the water from the pan; hence the sand has opportunity to settle onto the bottom of the pan and be carried up into the sandbox. Aseonsiderable water willbeswept into the sand-box, I provide a pipe or conduit, 26, shown in dotted lines in Figs. 2 and 5, which conducts any excess of water from the sand-box back into the pan, where any sand which may be carried back with such overflow will be caught, and can be carried back into the box by the wings 17. The sand is carried from the sand-box by the elevator-buckets 27, and delivered into the chute 2S, whence it is dischargcdinto a llat secured alongside of the dredging-boat.
In addition to hoisting the sand from the box 24 the buckets serve as agitators for agitating the sand and water in the box, and
thereby effecting the thorough cleansing of the sand from any impurities which may not have been previously removed, such impurities passing off with the water through the conduit 26, or said conduit may be so eonstruoted as to conduct the overflow into the river.
It is a prominent characteristic of my improved sand separator and washer that the washing is eitected in an unconfined body of water, and that the screen has an unobstructed discharge end, and by eflecting the washing and separation, as above stated, in an unconfined body of water, a more thorough and complete cleansing of the sand from mud and other impurities is attained.
I claim herein as my invention 1. The combination of a cylindrical screen, arranged to revolve with its lower part in the surface of an open unconfined body of water. such screen being slightly inclined downward toward its delivery end and having an unobstructed discharge, a concave sand-catching pan beneath, and wings on the screen adapted to sweep the sand out ofthe pan, substantially as set forth.
2. A. cylindrical screen arranged to revolve with its lower part in the surface of an open unconfined body of water, such screen being slightly inclined downward toward its delivery end, and having an unobstructed discharge, in combination with a concave sand-catching pan beneath, wings on the screen adapted to sweep the sand out of the pan, and an elevator constructed to collect and discharge the sand into chutes suitably arranged for delivery into the screen, substantially as set forth.
3. A revolving screen provided with peripheral flanges lit, in combination with a concave sand-catching pan arranged below the screen, said pan being provided with end flanges overlapping the flanges 16, and having an inwardlyqnojecting ledge 20, whereby the sand is prevented from being washed out of the pan at its ends, substantially as set forth.
t. A cylindrical screen provided with longitudinal wings 17, in combination with a concave sand-catching pan arranged beneath the screen, a sandcollecting box located at one side and in convenient proximity to the pan, and a conduit for conducting overflow from said box, substantially as set forth.
In testimony whereof I have hereunto set my hand.
PHILIP M. PFEIL. Witnesses:
