TYLER COMPANY, OF ,CLEVELAND, OHIO, A CORPORATION OF OHIO wovEN-wrmi sonnen Application filed December 27, 1927. Serial No. 242,917;

1`he present invention', relating as indicated, to a woven wire screen is more particularly directed to a new and improved v screen formed of two series of wires woven together to produce a screen having to an unusual degree the quality of free screening and the ability to resist clogging or blinding. A further object of the invention is the provision of a screen having an exceptionally long life and one in which a high degree of vibration can be secured due to the use of highly tempered wires in one series.

Fig. 1 is a plan'view of my improved screen; Fig. 2 is a section on the-line 2-2,

Fig. 1; and Fig. 3 is a section on the line 3--3 in Fig. 1. y v

Referring now to Fig. 1, there is shown a\woven wire screen consisting oftwo series of interwovenwires, of which one series,

comprising the wires 1, are disposed inv spaced parallel relation, while the other series, comprising the wires 2,.are arranged l in bands. or groups of parallel ybut closely compacted wires'.

The wires 1 may be perfectly straight as lillustrated in Figs. 1, 2 and 3, andsince these wires are not crimped or bent as in most screens for the engagement of the other series of wires they may be formed of harddrawn wire of a very high degree of iexibility and temper and can thus be made. to possess the qualities which will impart to the screen a high degree of vibration in use and a long li e due to the hardness of these wires.` It will be readily under'- stood that ifthese wires, after being drawn,

had still to be bent and crimped, it would produce an additional temperV and hardness in the wire at the'points of bending, which would require the original condition of the wire to be considerably softer than is the case with the wires just described, in order not to produce an excess hardness and brittleness at the bent portions.

T he transverse wires consist of either square or rectangular lwires (in cross-section) which are woven about the parallel spaced round wires of the first series in separated groups. By the use of either square or rectangular wires a very much increased area of engagement between the transverse and longitudinal wires is secured than is possible where round wires arel used for both the longitudinal and' transverse series. With wires of the cross-sectional area indicated a surface slightly greater in width than the normal width of the wirel is engaged at each band on one of the wires of the first series since the transverse wires iatten out slightly when being crimped and woven, and thus increase-the normal area of contact, as indicated in Fig. 1, by the bulged lateral portions 4.

The series of transverse wires employed in spaced groups may be permanently secured in place by welding orother means at spaced points 5 and 6 onone side of the group and at similar spacedv points 7 and "8' on the other, the outermost wires of each group beingthus secured to certain of the wires `of the other series and thus acting to retain the vgrouped wires vin that relationl ship and prevent'the slipping of any of the wires out of their original and predetermined position.

. My improved screen has a materially longer life than screens heretofore used for the samepurpose by reason of the greater temper and hardness which can be used in the longitudinal wires. It also has a qual-l ity of free screening by reason ofthe large areas in which there are no transverse wires. In additiontovthese advantages the permanent fixing ofthe relationship between longitudinal and transverse wires maintains a high degree of accuracy of classification y throughout the entire life of the screen.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

l therefore particularly point out and distinctly claim as my invention 1. A woven wire screen comprising a series of spaced parallel wires, and a second series p of transverse wires, the wires of said second Cil series being arranged in spaced groups, and the two outermost wiresin each such group being secured to certain of the wires of the first-named series.

2. A woven wire screen comprising a series of spaced, straight, parallel wires, and a second series of transverse wires, said transverse wires being arranged in spaced groups and being of rectangular cross-section, t e two outermost wires in each group being united to certain of the wires of said irstnamed series. i

3. A woven wire screen comprising a series of spaced, straight, parallel wires, and a second series of transverse wires, said transverse wires being arranged in spaced groups and being of square cross-section, the two outermost wires in each group being united. to certain of the Wires of said first-named series.
