UNITED ,STATES PATENT OFFICE.,
WILLIAM osMoNn, on New YORK, N- Y- IMPROVEMENT IN SAND-SCREENS.
Specification forming part of Letters Patent No. 36,104, dated August 5, 1862.
To all whom, may concern:
Be it known that I, WILLIAM OsMoND, of No. 167 EastTwelfth street, in the city, county, and State of New York, have invented a new and useful Improvement inthe Construction of Sand-Screens; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a facev or front view of a sandscreen a portion of which is constructed ac cording to my invention; Fig. 2, a section of the same, taken in the line a; sc, Fig. 1; Fig. 3, a section of a part of the same, taken in the line y y, Fig. 1.
Similarletters of reference indicate corresponding parts in the several ligures.
Thisinvention consists in attaching the wires to the screen in such a manner .that they will be retained much moreiirmly in position than those attached in the usual way, and also form a stronger and more durable screen, one that will not be injured by the scraping of a spade overita means usually employed by workmen to eiean the screen when choked by gravel-f the wires also being capable of resisting the action of the spade, so as not to become bent or injured by its action.
To enables those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents the frame of a sand-screen, which may be constructed, as usual, of two parallel side-pieces, a a, connected at their upper and lower parts by cross-bars b b. This frame A, between the two cross-bars b b,- has metal rods c tted transversely vin it at equal distances apart, in the same way as those of ordinary screens. The ordinary screens, however, have their longitudinal wiresd attached to the rods c by meansof small annealed wires e, which are wound around them and the rods c, as shown in Fig. 1, and herein consists the difference between the construction ofthe old and my improved screen.
I attach the longitudinal wires, which aredesignated by d,to the cross-rods c by twisting the wires one or more times around each rod c, as shown at c* in Figs. 1 and 2, and
metal rings or collars f are placed on the rods c and between the convolutions of the wires. 011e or more rings f mayV be interposed between the wires d, according to the width of the spaces required between lthem, and said rings or collars may be formed of wire of the same thickness as the wires d. The ends of the wires d may be simply covered by metal plates g g, without being attached to the crossbars b b.
This mode of construction possesses many advantages over the old. In the lirst place, the wires d are kept in a proper degree of tension between the cross-rods c, as they are firmly attached to each crossrod, and consequently cannot be bent or sunk in between them under the blows ot' the spade, as is the case with the wires d attached tothe rods cin the old way, which are merely retained or fastened at their ends, the wires e not serving to prevent the stretching of the wires. In the second place, my improvement prevents any lateral shifting of the wiresd, as a perfect bearing is obtained from one end' of the rods c to the other, each wire being keyed rmly in position one against the other. The wires e of the old screen will not'effect this result. I-n the third place, the improvement gives a smooth surface to the face of thescreen. There are no projecting parts for the spade to catch against and wear and knock off in being scraped over the screen, as is the case with the wires e in the old screen. They are soon broken or injured by the spade or the friction of' the gravel, and the screen consequently requires frequent repairs, the expense of which frequently amounts to half the original cost.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
A sand-screen having its wires dsecured to its cross-rods c by twisting the former around the latter, and either with or without the rings or collars f interposed between the wires, substantially as described.
WILLIAM OSMOND.
