Specification of Letters Patent.

Patented May is, 1909.

Application filed December 26, 1908. Serial No. 469,499.

. reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This. invention relates to ap aratus for feeding'liquid and for mixing anr vaporizing the liquid with air, especially for mixing and vaporizing gasolene with atmospheric air, or for mixing as or alcohol with air, to produce gaseous or ydrocarbon fluid-for use in explosive engines, the invention having referenoe particularly to improved means whereby the li uid is fed and vaporized with the air. The 0 ject of the invention-is to provide 'an improyed mixer and vaporizer of the above-mentioned character of compact form and. which may be manufactured chea ly, and be durable, efiicient and economica in use. 1

With theabove-mentioned and other objects in view the invention consists in an improved mixer and vaporizer comprising a case having a centrally disposed valve-seat body member therein, on which is an externally arranged annular valve-seat, and in which are ifeed ducts terminating or having their outlet orifices in the valve seat, a valve for regulating the flow of liquid through the ducts, and a combined valve and vaporizer operating as a piston in the case and having an internally arranged valve face normally seated on the valve-seat and covering the feed. ducts, all of novel construction and arrangement; and the invention consists further in. the parts and combinations and arrangements of parts as hereinafter particularly described and then defined in the accompanying claims.

Referring to the drawings Figure 1 is an elevation.- pf the improved mixer and vapori'zer; Fig32, a longitudinal sectional view on the line A A in Fig. 1; Fig. 3, an end view or top plan of Fig. 1 partially broken away;

Fig. 4, an elevation or side view of the combined valve and vaporizer partially in section; F i 5,'a.transverse sectional view on the line .B. in Fig: 2 partially broken away; Fig. 6, asfragmentary perspective view of the portion having the valve-seat body member therein; Fig. 7, an end or plan View of the combined. valve and vaporizer slightly modified and Fig. 8, a top plan of the portion of the case having the valve-seat .body member therein slightly modified.

Similar. reference characters in the drawings indicate corresponding elements or features of construction referred to herein.

As preferably constructed the case of the mixer and vaporizer comprises a number of sections of circular form and suitably jointed and fitted together, there being an inlet end section 1 having internal screw-threads 2 and external lugs 3, the sectionbeing designed to receive the atmospheric air and to be connected to an air inlet-pi e, if desired. A middle section 4 is joine to the section 1, and an end section 5 is joined to the section 4 and has external lugs 6, the thrcesections being held together rigidly by a suitable number of bolts 7 connected with the

lugs

3 and 6. The outlet or upper end of the section 5 has external screw-threads 8 thereon whereby the case may be connected tightly to the cylinder or explosion chest of anengine or to a pipe. The case may be arranged either in upright position, as shown, or at any angle to the perpendicular that may be desired without detracting from the efficiency of the a paratus in operation, but for the purposes oi description the apparatus is considered as being vertical or with its longitudinal axis in vertical arrangement.

The middle section 4 of the case has a circular'valve seat body member '9 supported centrally therein by means of

arms

10, 11, 12, cast integrally therewith, so that air may pass between the wall of the case and the valve seat body'rnember, the latter having a vertical duct 13 therein extending centrally from the top toward the bottom thereof,and an annular valve-seat 14 is formed on the upper edge portion of the body member, so as to be llke the frustum of the cone in shape on its face, or beveled, the valve-seat preferably having a small annular groove 15 in its face, a suitable number of feed ports. as 16, 16, 16", being formed in the body member in communication with the duct 13 and terminating in the valve-seat 14 or in the groove 15, the feed ducts being arranged radially to the axis of the duct 13 and inclined thereto, so as to extend approximately at right angles to the plane of the face of the valve-seat 14.

The ducts are 7 preferably formed by drilling, after which the upper end of the duct lit gs closed by a plug 17 or otherwise, as may be desired.

The section 4 of the case has a branch 13 formed thereon that extendslaterally from the exterior opposite the arm 10, and has a chamber 19 therein that extends through the wall of the case section and into the valve seat body member 9 nearly to the duct 13,'there being a valveseat 20 formed at the inner end of the chamber from which extends a relatively short duct 21 that communicates with the duct 13. The branch 18 hasa nipple 22 formed thereon in which is a passageway 23 communicating with the chamber 19 to receive the liquid or a gaseous fluid, the nipple having external scre'w threads 24 for connecting a supply pipe thereto. A valve-stem 25 having screwthreads 25 is screwed into the branch 18 and has a needle point valve 26 on its inner end that operates in connection with the valveseat 20, the outer end of'the valve-stem having a hand-wheel 27 thereon, and a packing nut 28 is employed to prevent leakage of the liquid from the chamber 19.

The upper or outer end of the section 5 of the case has a valve-stem guide 29 supported therein by integral arms 30 for assisting to guide the combined valve and vaporizer which comprises an annular body part 31 that is fitted closely and is movable as a piston against the inner side of the wall of the case, and in some cases is provided with a packing ring 32 to preventthe passage of air past the valve-body. The under side of tliti valve-body has an internal annular beveled ,valve face 33 formed at the inner side thereof to correspond with the contourof the valve- I in the valve-seat, the two grooves together forming a channel which forms communica 45,

tion between all the feed parts 16,01 16, so that in some cases the hquidmay fill the channel while the valve is closed, and obviously, if desired, the valve-seat 14 may be made Without a groove 15,and also the groove 34 may be omitted, the plain valve face and seat being shown in Figs. 7 and 8; or the groove may be made in only, one art either in the valve-seat or in the valve-iace.

The valve-body has a flange orskirt extending from and below the underside 31 of the valve-bod and it extends against the inner side of t 1e case, so that-the under side of the valve-body is practically cup shaped to'induce the air to flow through the opening 36 of the valve-body rather thanpast the outerv side of; the body. A suitable number of posts 37 are formed on the top or upper side of the valve-body, and a disk 38 is formed on the tops thereof that preferably has a conical shaped under side 39 to deflect and assist in vaporizing the liquid, the upper has a shoulder 41 adapted to engage the guide when the valve is lifted excessively, the valve being normally held on its'seat to cover the ports by a spring 42 extending about the stem 40 and seated against the disk 38 and the guide 29.

In practical use the valve Wheel 27 will be turnedto admit liquid from the chamber 19 into the duct 21, from whichthe liquid will flow through the duct 13' and through the ports as 16 to the face 33 of the valve and into the grooves that may be formed in the valve face and the valve seat Where the liq,- uid will be confined until released by unseating the valve. During the movements of the explosive engine the piston in the engipe-cylinder will at intervals produce a partia vacuum in the outlet end of the case of the mixer ands-vaporizer, so that the atmospheric pressure exerted against the under side 31' of the valve-body will lift thevalve from its seat It Will be understood, of course-that the' mixer and vaporizer may be used for other purposes than that described and obviously may be operated otherwise than by section or vacuum, as for instance the air maybe supplied in impulses by an air ump for lifting the valve and va orizing t e liquid.
