H. HAMPER. Means for Cleansing the Meshes of Belting Screens. v V N'o. 229,121; Patented June 221880.
UNITED STATES PATENT OFFICE.
HENRY HAMPER, OF PLYMOUTH, MICHIGAN, ASSIGNOR TO HUNTLEY, HOLGOMB & HEINE, OF SILVER GREEK, NEW YORK.
MEANS FOR CLEANSING THE MESHES OF BOLTlN'G-SCREENS.
SPECIFICATION forming part of Letters Patent No. 229,121, dated June 22, 1880.
Application filed June '21, 1879.
To all whom it may concern:
Be it known that I, HENRY HAMPER, of
' Plymouth, in the county of \Vayne and State of Michigan, have invented new and useful Improvements in Means for Cleansing the Meshes of Bolting-Screens, of which the following is a specification, reference being had to the accompanying drawings.
My invention relates to a device for jarring or agitating the bolting-cloth of the vibrating screens in middlings-purifiers and other machines, so as to prevent the meshes thereof from clogging or filling up.
Previous to my invention these vibrating screens have been provided with various me-v chanical devices-for instance, brushes, knockers, and air-blasts-for keeping the meshes of the bolting-cloth open; but these devices are more or less objectionable on account of their expense and their liability of getting out of order.
The object of my invention is to provide a simple and cheap device for accomplishing the desired result; and my invention consists of loose balls passed back and forth over the surface of the bolting-cloth by the motion of the vibrating screen, as will be hereinafter fully set forth. 1
In the accompanying drawings, Figure 1' is a sectional elevation of a shaking sieve provided with my improvement, and Fig. 2 is a perspective view thereof.
Like letters of reference designate like parts in both of the figures.
A represents the rectangular screen-frame; B, the bolting-cloth, and 0 one or more longitudinal stiffening -bars connecting the head and tail pieces of the screen-frame.
dare the lower cross-bars, which support the bolting-cloth, and e the upper cross-bars, connecting the longitudinal bar 0 with the side pieces of the screen-frame, and arranged sufficiently above the bolting-cloth to allow the material to freely pass under them.
A vibratory or reciprocating motion is imparted to the screen by any common and wellknown mechanism.
f represents loose balls, preferably constructed of rubber or other elastic material, and placed upon the bolting-cloth within each of the compartments formed by the screenframe and its longitudinal and cross pieces 0 e.
The screen-frame is slightly inclined toward its tail end, or hung so that its vibratory mo tion will impel the material toward the tail end in the usual manner.
The movement of the screen causes the balls f to pass over the bolting-cloth in a peculiar dancing or jumping motion in the direction in which the material moves over the same until the balls strike against the tailboard of the compartment in which they are contained, when the impact will return the balls at once to the opposite end of the compartment. In this mannerthe balls are caused to pass backward and forward over the bolting-surface, whereby the latter is continually jarred or agitated and its meshes prevented from filling up.
When non-elastic balls are employed the requisite elasticity may be obtained by lining the tail end of each frame-compartment with a material possessing sufficient elasticity to return the balls by this impact to the header the compartment. 1
My improved means for clearing the meshes of the bolting-cloth is very simple and cheap, entirely noiseless in its operation, and not liable to get out of order.
If any particular portion of the screen is more liable tobecome clogged than other portions a greater number of balls may be placed in the compartments over such portion of the screen, thus enabling the attendant to regulate the jarring action in accordance with the 8 5' requirements of the various sections or portions of the screen.
I claim as my invention- 1. The combination, with a shaking screen provided with open pockets or compartments, of loose balls placed in said compartments, and confined thereby to certain portions of the screen, whereby each ball is caused to pass back and forth over that portion of the screen only which is inclosed by the compartment in which the ball is contained, and the
