DEVICE FOR TEMPERING WHEAT.

specification of Letters Patent. Patented Aug. 19,1913.

Application iled August 28, 1912. Serial No. 717,574.

T0 all whom t may concern Be it known that I, FRANK F. BOND, a citizen of the rUnited States, residing at Noblesville, in the county of' Hamilton and4 State of Indiana, have invented new and useful Improvements in Devices for Tempering Wheat, of which the following is a specification.

This invention relates to devices for tempering wheat and other grains by spraying the same with water preparatory to milling the same.

The invention has for its object to produce a spraying nozzle of simple and improved construction whereby the desired result may be effected.

A further object of the invention is to produce a simple and improved spraying nozzle having means whereby the operation may be regulated.

YWith these and other ends in view which will readily appear as the nature of the invention is better understood, fhe same consists in the improved construction and novel arrangement and combination of part-s which will be hereinafter Jfully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,-Figure 1 is a side view of a nozzle constructed in accordance with the invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view taken on the line 3 3 in Fig. 2.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved nozzle comprises in it-s construction an outer cylindrical tube l and an inner tube 2, which latter is located concentrically within the outer tube, extending about half way therethrough, said inner tube being provided at one end with an elbowI 3 which is connected with the side wall of the outer tube, as shown at 4, so as to produce an inlet aperture 5 communicating with the inner tube. The outer tube is provided at vreception of a sleeve 9 having an interior annular flange 10 the opening through which flares outwardly, as shown. That portion of vthe tube B which projects beyond the front end of the tube A is provided with an annular recess 11 of V-shaped cross section,.and at the bottom of said recess are formed apertures 12 through which water may escape, the eXtreme front end of the tube 2 being obstructed by a plug 13. A portion of the tube 2 in front of the V-shaped recess 11 is exteriorly threaded for the reception of a cap or sleeve 14, the inner end of which has an annular V-shaped flange 15 projecting in the direction of the flange 12 of the cap 9, but spaced from the latter so as to present an annular aperture 16. A similare annular aperture 17 exists between the inner edge of the ange 10 and the annularly recessed po-rtion of the tube 2, said annular aperture 17 being formed between the inclined rear portion of the wall of the il-shaped recess 7 and the inner edge of the flange 10. It will be obvious that by proper adjustment of the cap 9 upon the threaded end of the pipe, the area of the aperture 17 may be increased or diminished at will, thereby regulating the escape of compressed air. The area of the aperture 16 may be regulated by adjustment of' the sleeve or cap 14, as will be readily understood.

In the operation of this device, it is intended that the water shall be supplied under little or no pressure, the quantity of water being regulated by simple well known means, such as an ordinary valve 18 on the supply pipe 8. The quantity of the water supply may thus be effectively regulated. The water escaping in numerous small jets through the aperturps 12 will be subjected to the pressure of the annular air et issuing through the aperture 17, and the velocity oft which may be regulated by proper adjustment of the cap 9. The spray thus formed 'will issue through the annular aperture lfm and the velocity thereoll inay be regulated by proper adjustment ot the cap or sleeve lll.

Having thus described the invention, what is clainielfl as new, is

l. l'n a device oit the class described, an external tube. an inner tube having` an elbow connected to the Wall of the outer tube, said inner tube extending beyond the front end of the orter tune, and the projecting portion of said inner tube being` provided with an annular recess lli-shaped in cross section and with an annular series of perforations at the bottoni oi said recess, a plug obstructing the front end oit the inner tube, a sleeve threaded on the front end ot the outer tube and having a. forwardly beveled flange extending in the direction of the recessed portion of the inner tube and spaced therefrom to produce an annular' discharge aperture7 the area of which may be regulated by adjust-nient of the cajnand a sleeve threaded upon the inner tube and cooperating with the tlanged cap to produce an annular discharge aperture, the area of which inay be varied by adjustment of the sleeve,

2. A. nozzle comprising` inner and outer tubular ducts, a sleeve adjustable upon the enter duct and cooperating` with the inner duct to control the quantity of fluid issuing between said outer duct and the inner duct, and a sleeve adjustable on the inner duct and cooperating` with the sleeve on the out/er duct to vary the area of the annular opening between said sleeves.

In testiinony whereof I affix iny signature in presence of tivo Witnesses.
