SPECIFICATION forming part of Letters Patent No. 617,197, dated J anuary 3, 1899..
Application filed June 1, 1897. Serial NO- 638,886. (No model.)
To aZZ whom it may concern.-
Be it known that I, EDWARD 0. SMITH, a citizen of the United States, and a resident of Oskaloosa, in the county of Mahaska, State of Iowa, have invented certain new and useful Improvements in Screens, of which I do declare the following to be afull, clear, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.
Figure 1 is a plan view of a coal-screen embodying my invention. Fig. 2 is a view in vertical section on line 2 2 of Fig. 1. Fig. 3 is a view in vertical cross-section on line 3 3 of Fig. 1. Fig. 4: is a detail view of one of the disks. Fig. 5 is a side view of a portion of the main frame, showing the adjustable shaft-j ournals thereon.
The present invention has for its object to provide a simple, effective, and durable construction of apparatus for the screening and grading of coal, ore, or similar material 3 and this object of invention is accomplished by the novel features of construction hereinafter described, illustrated in the accompanying drawings, and particularly defined in the claims at the end of this specification.
The main frame of the screen is shown as comprising suitable side bars A and A and a central bar A and upon the top of each of these bars is mounted a U-shaped angle-bar B, these angle-bars being connected to their respective bars by suitable through-bolts a. The top of each of the angle-bars B is provided with a long slot b, that extends approximately from end to end thereof, and through which pass thethrough-bolts c, that hold in place the journal-boxes 0, wherein are journaled the shafts D. By thus adjustably mounting the boxes 0 upon the angle-bars D the shafts D can be shifted toward and from each other for the purpose to be presently stated. Upon each of the shaftsD is mounted a series of disks or plates E, having, preferably, scalloped or like irregular edges, and these disks are keyed to the shafts preferably by forming each of the shafts D with one or more longitudinal grooves, into which will fit smalllugs or keys cl, projecting inwardly from the central openings of the disks or plates E. In order to properly interspacethe plates or disks E upon the shafts D,I preferto employ suitable washers, one or more of these washers being interposed between the disks or plates E, as shown in the drawings. The washers and disks are removably held upon the shaft, and by placing any desired number of washers between the disks the width of the spaces between the disks can be varied as desired. For certain classes of work it is desirable that the washers should be non-revoluble, and I have therefore shown the washers F as formed each with a central hole to permit said Washer to be slipped freely upon its shaft D, and thus allow the shaft to revolve while the washers remain stationary. Preferably each of the washers F (when nonrevoluble washers are used) is'formed with a downward extension f, having a transverse hole therein through which will pass a tierod G, that extends through the holes of all the Washers F that are mounted upon the same shaft. The ends of the tie-rod G pass through suitable holes formed in the vertical plates of the angle-bars B, the ends of the rods G being furnished with nuts, if desired. Upon the corresponding end of each of the shafts D is keyed a beveled pinion II, that meshes with a correspondingly-beveled pinion I, mounted on the driveshaft K. The driveshaft K is journaled in suitable bearings,and the beveled pinions I are adjustably mounted upon the shaft by suitable keys and keyseats, so that the beveled pinions I can be adjusted back and forth along the shaft in correspondence with the adjustment of the shafts D and their pinions I-I. One end of the shaft K is provided with a suitable sprocket-wheel or pulley K, whereby motion is imparted to the various shafts from a suitable source of power.
From the foregoing description it will be seen that when motion is imparted to the shafts D the disks E will be caused to revolve, the scalloped edges of the disks turning or tumbling the lumps of coal, and thus insuring the passage of lumps of proper size between the interspaced disks, while the larger lumps pass onward to the bottom of the screen. As
the disks upon one shaft are arranged opposite the spaces between the disks of the adjoining shafts, it will be seen that the spaces between said disks determine the size of the lumps of coal or like material that shall pass are removable it is obvious that the distance apart between the plates or disks E may be varied as desired by the interposition of the required number of washers F. It will be understood, of course, that the tie-rods G are removable endwise from the washers F and the U-shaped angle-bars Bin order to permit the adjustment of the disks or plates in manner above indicated.
While I have described what I regard as the preferred embodiment of my invention, it is manifest that the details of construction above set out may be varied by the skilled mechanic without departing from the spirit of theinvention. It is obvious also that features of the invention may be employed without its adoption as an entirety.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A screen for coal or similar material comprising a suitable supporting-frame, a sewhereby said spaces are left unobstructed to permit the material to descend therethrough, substantially as described.
2. A screen for coal or similar material comprising a suitable supporting-frame, a series of adjustable transverse shafts sustained by said frame, a drive-shaft geared to said adjustable shafts so as to cause them to run in one and the same direction, said adjustable shafts being provided with a series of interspaced disks, the disks of certain of said shafts being arranged opposite the spaces bej tween the disks of adjacent shafts whereby said spaces are left unobstructed to permit the material to descend therethrough, substantially as described.
3. A screen for coal or similar material comprising a suitable supporting-frame, rotary shafts having revolulole disks mounted thereon, adjustable journal boxes for said shafts and slotted angle bars extending lengthwise of said supporting-frame and bolts extending through the top plates of said slotted angle-bars and serving to adj ustably connect the journal-boxes therewith, substantially as described.
4:. A screen for coal or similar material comprising a suitable supporting-frame, a series of transverse shafts sustained by said frame, a drive-shaft suitably geared to said transverse shafts to rotate the same in the same direction, said transverse shafts being provided with a series of disks and a series of independent washers interposed between said disks, said disks and said washers being removable endwise from said shafts, the disks of certain of said shafts being arranged opposite and substantially outside the spaces between the disks of adjacent shafts whereby said spaces are left unobstructed for the free descent of the material substantially as described.
5. A screen for coal or similar material comprising a. suitable supporting-frame, a series of adjustable transverse shafts sustained by said frame in the same direction, a drive-shaft geared to said transverse shafts to rotate the same, a series of disks removably mounted upon said transverse shafts and a series of independent washers interposed between said disks and removably mounted upon said shafts, said disks and said washers being so relatively arranged that the spaces between the disks are left unobstructed at each side of the shafts for the free descent of the material, substantially as described.
6. A screen for coal or similar material comprising a suitable supporting-frame, a series of transverse shafts sustained by said frame, a drive-shaft geared to said transverse 1 shafts to rotate the same, a series of disks mounted upon each of said shafts and a series of non-revoluble washers interposed between said disks, provided with depending arms, means engaging said arms for holding said washers in stationary position; said disks and said washers being so relatively arranged that the spaces between the disks are left unobstructed at each side of the shafts for the free descent of the material, substantially as described.
