SPECIFICATION forming part of Letters Patent No. 489,738, dated January 10, 1893.

Application filed March 28, 1892. Serial No. 426,885. (No model.)

To all whom it may concern;

Be it known that we, EUGENE G. HAMMOND and EDWARD D. HAMMOND, residents of the town of Hanover, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in WVashing and Sizing Machines, of which the following, in connection with the drawings accompanying and forming a part hereof, is a full and complete description, sufficient to enable those skilled in the art to understand and make the same.

The purpose of our invention is to obtain a device whereby sand, gravel, coal, and other like material can be elevated, water applied thereto, if desired, and the material with the water when applied, conveyed to a rotatable screen, and such material,and water, if water is used, be discharged from the screen and the material thereby sized and conveyed to a second screen, where the same operation is repeated until the material is separated into the several sizes desired, and where the water is used as suggested such material in addition to being sized is Washed.

WVe have illustrated our invention by the drawings accompanying and forming a part hereof, in which: 1

Figure 1, is a side elevation of coal, gravel, or sand bins having a machine embodying our invention mounted thereon; Fig. 2, avertical longitudinal section of one of the rotatable screens entering into the device with the several spouts in position therewith; showing a construction of the perforated cylinder; Fig. 3, an elevation on line 3-3 of Fig. 1, viewed in the'direction indicated by the arrows; and Fig. an end elevation of the end of a cylinder embodying certain additional inventions which may or may not, as desired, enter into the construction of the device, illustrated in Fig. 1, as embodying our invention.

The same letter of reference is used to indicate a given part where more than one view thereof is shown in the several figures of the B, is a hopper; and b, is a spout extending therefrom, to and delivering into the inside of the perforated cylinder D entering into and forming one of the elements in. the construction embodying our invention.

D, D D are perforated cylinders constructed and mounted in the same manner and for the same purposes as is the cylinder D, the only difference being in the size of the foraminations or perforations of the cylinder whereby the material passing from the cylinder through such perforations or foraminations is graded or sized.

E, is a water pipe; and e, is a pump by which water is raised in pipe E and delivered into the hopper B.

d, d, are the holes or perforations in the several cylinders D, D, D and D Cylinder D as well as the several cylinders D, D D respectively, are illustrated in Figs. 1 and 2 as mounted on the top timbers X of the bins in the hangers F, F, and rotating in such hangers on the shaft G, such shaft forming the axis of the cylinders respectively, and having thereon arms G extending out to and supporting the foraminated cylinders.

g, is a collar on shaft G holding it in position, that is, receiving the downward thrust of the revolving cylinder and shaft.

H, is a sprocket wheel on shaft G; and h, is a sprocket chain extending from the sprocket wheel H to and over sprocket wheel h on main driving shaft H.

I, is a spout extending from under the cylinder D to and delivering its contents into the cylinder D 5 and I, I respectively, are like spouts underneath cylinders D, and D 1 is a spout underneath the cylinder D The several spouts I, I, I I receive therein the material passing from the several cylinders, located over them, through the perforations therein, and the material in such cylinders not passing through the perforations extends the length of the cylinder and passes out of the other end thereof into or on the spouts or hoods J, J, J and J respectively.

WVhere, as in Fig. 1, this machine is placed over bins A, A, the spouts or hoods J, J, J and J respectively, serve merely to protect the spouts I, I, I 1 respectively, from receiving the contents of the cylinders delivered out of the ends thereof and may ibe'a mere hood, but where the material delivered from the end of the cylinders is to be conveyed any distance therefrom a spout is necessary.

As will be readily understood by inspection of Fig. 1, the manner of'operation of this device is, the material and water is delivered from the hopper B through the spout 1) into the cylinder D, the finer material therein, cylinder D being continuously rotated, passes through the perforations d together with the water, or nearly all of the water, and falls into the spout I, I, while the material not passing through the perforations d extends through the cylinder D passing out of the lower end thereof on to the hood J from which it falls into the bin A underneath the cylinder D. The liquid and finer material passing into the spout I, as described, extends along in said spout and is delivered into the cylinder D Where it is again sized, the smaller pieces thereof passing through the perforations 61 in the cylinder D together with the liquid into the spout I being delivered into the next adjacent cylinder in the same manner, while the particles or pieces of the material not passing through the perforations d in cylinder D extend through the cylin der and out of the end thereof in the same manner as last described, in regard to the cylinder D, and on to the spout or hood J, falling into the bin A thereunder. As many of the cylinders D, D, D and D are employed as required, the material being delivered as described from one to the next adjacent one.

By this device the liquid employed in Washing the material can be and is retained until the material is completely washed and sized, the manner of working of the device being to separate the finer from the coarser particles, to deliver the coarser into its bin or other receptacle, and to carry the finer particles and the liquid to another screen and there repeat the operation, whereas heretofore the finer particles being separated from the machine employed, first, the coarser particles were separated farther along in the machine, and thereby the finer particles alone .Were contained in the Water while the material was being sized and washed and with such machines the first of the bins A to the left end of the drawing Fig. 1, would receive the finer particles while, with our device, it receives the coarser particles; the next bin would receive a grade coarser while with us, the same bin receives a grade finer material, and so on.

In the modification illustrated in Fig. 4-, the shaft G and the arms G are not used, but in place thereof there is placed on the cylinder D ring K having thereon gear teeth 70, 7c, intermeshing with the teeth on a driving gear K. And the cylinder D rests on the revoluble pulleys or wheels L, L, such pulleys L turning on shafts 1,1, respectively. As the cylinder D is precisely the same as the several cylinders D, D, D D inclusive, except the shaft G and spokes G, being removed from within the cylinder, material of larger size in proportion to the size of the cylinder can be passed through the same.

It is to be understood that the several cylinders vary only in the size of the perforations and that the letterings D,D, D ,D D, have been given thereto, to avoid confusion in the describing of the device.

The several spouts b, I, I, I and I and the spouts or hoods J, J, J J respectively, form conveyers in which the material received thereon, is conveyed to the point of delivery thereof hereinbefore set out, and we do not confine ourselves to the precise shape of such conveyers, or to the exact location thereof as regards distance from the several cylinders, or to the size thereof it being, however, necesary that the conveyor 1) deliver it contents into the first of the cylinders, that the series of conveyers I, I l and I extend, respectively, longitudinally underneath the several cylinders sufficiently near and of sufficient size to collect all the material coming through the foraminations in the cylinders, and that each of such conveyers must extend to and deliver the contents thereof as hereinbefore stated; and that the conveyers formed by the hoods or spouts J, J, J J respectively, must fully protect the spouts I, I, I 1 from receiving any of the material passing out of the ends of the several cylinders, and Where such conveyers-J, J, J J are designed to carry the material delivered into them a distance, that they be of sufficient size, proper shape and suitable construction to receive such material and convey the same as desired.

Having thus described our invention, What We claim as new and desire to secure by Letters Patent is:

In a washing and sizing machine, a main driving shaft having sprocket wheels thereon, a series of rotatable foraminated cylinders all driven from said main shaft by chains passing over the sprocket wheels thereon, a pump driven by a chain passing over a sprocket wheel on said main shaft, and a hopper, into which said pump discharges, for feeding material to said cylinders, substantially as described.

EUGENE G. HAMMOND. EDWVARD D. HAMMOND.

In presence of CHARLES T. BROWN, EDWARD M. BARNARD.
