\VILLIAM JOHN LOUGH, OF ALTAIWIONT, KANSAS, ASSIGNOR OF ONE-HALE TO AUGUSTUS WOLF, OF OIIAMBERSBURG, PENNSYLVANIA.
CLEANER FOR SIEVES OF BOLTlNG-MACHINES.
SPECIFICATION forming part of Letters Patent No. 573,674, dated December 22, 1896.
Application filed July 2'7, 1895.
To all whom it may concern.-
Be it known that 1, WILLIAM JOHN LOUGH, a citizen of the United States, and a resident of Altamont, Labette county, Kansas, have invented certain Improvements in Cleaners for Sieves of Bolting-Machines, of which the following is a specification.
My invention consists of a simple and practicable means of automatically cleaning the sieves of bolting-machines, especially those of gyrating bolts, in which the sieves have circular movements in a horizontal plane imparted to them, as indicated by the arrows, Figure 1, and thisobj ect I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Fig. 1 is a plan view of a bolting-sieve with cleaner therefor constructed in accordance with my invention, and Fig. 2 is a longitudinal sectional view of the sieve.
The sieve may be of any ordinary construction, that shown in the drawings consisting of an outer frame A, having bolting-cloth B secured to the top of the same and having suitable longitudinal and transverse supportingbars a beneath said bolting-cloth. The construction of the screen, however, forms no part of my present invention and may be modified in any way which circumstances may suggest without departing therefrom.
For cleaning and keeping clean the meshes of the bolting-cloth I employ one or more loose chains D, connected at the opposite ends to the frame of the screen and having such an amount of slack that all portions of the bolting-surface of the screen can be reached thereby. In the drawings I have shown two of these chains D, connected at their opposite ends to the end bars of the sieve-frame, but, as before indicated, a single chain may be used or more than two chains may be employed, provided there is sufficient slack to permit access of the chain or series of chains to all parts of the screen.
As the screen is moved about in a horizontal plane the chains resting on the upper surface of the bolting-cloth are shaken about on the same and are constantly changing position, traveling over the entire surface of the cloth in irregular paths, so that they act as scrapers and effectually prevent any such accum ulation of material on the cloth as would tend to clog the pores of the same.
Serial No. 557,354. (No model.)
Owing to the fact that the chain is confined at both ends, it is impossible for it to become bunched in one-part of the screen, as it might do if it were free at one end, and it is equally impossible for the chains to become entangled or wrapped one around another, so as to defeat their intended purpose.
The chains may be composed of uniform links or of alternate long and short links or may be constructed in any manner which will not interfere with the performance of their proper function.
It will be seen from the foregoing description that the essential advantage of my cleaner over the prior art lies in the facts, first, that the path of the chain moving over the screen is irregular; second, that the ends of the chain are confined with sufficient slack to permit the links of the chain to reach all portions of the screen; third, that owing to the universal flexibility of the individual linksof the chain with reference to one another, combined with the gyratory motion of the screen, the points of contact between the screen and the links of the chain are numerous and cover the whole face of the screen, all of which contribute to secure the most complete and perfect cleaning action, which is not possible with any other cleaner employing chains or the like heretofore known.
Instead of extending longitudinally along the screen the chains may, if desired, extend transversely across the screen, the same result being attained in either case.
Having thus described my invention, I claim and desire to secure by Letters Patent The combination with a gyrating boltingsieve, of a cleaner consisting of one or more chains secured at opposite ends to the frame of the sieve and having such slack as to permit the chain to travel over the face of the screen, in irregular paths as the sieve gyrates, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WILLIAM JOHN LOUGI'I.
