To all whom it may concern.'

Be it known that l', OsoAnC. Krans, Jr.,

had to the accompanying drawings, which form a part of this specification. v

My invention relates to carbureters, and

consists in the improvements hereinafter described and pointed out in the claims.

In the accompanying drawing, Figure 1, is a sectionv oiia 1*vertical plane of' an apparatus'lembotlying my invention. Fig. 2, is a planfview of the same in section on the line a, a, Fig. l. Fig. 3, is a detailed sectional view of the plug f, taken on the line 7), b, Fig. l. 'v

c, c, is the gasolene reservoir; d, d, is a basin extending into the reservoir c concentric therewith. The reservoir o has a concentric opening c in its bottom.

d1 1s a hollow cylindrical projection eX- tending downward from the basin d; theinterior of the basin around the opening from the projection Z1 is finished accurately conical and provided with an annular ridge g1 concentric therewith and bounding thev accurately finished conical surface of the bottom of said basin.

f' is-a plug formed to fit in the interior of the projection Z1 and having a flaring conical head adapted to iit against the bottom of the basin Z adjacent to the opening of the projection d1 and between the contiguous portions of the bottom of the basin and of the head of said plug and the ridge f/l the lower conical portion of y,said head is out away, by` turningfin a lathe, so as to leave a surface parallel and closely adjacent'to the surface of the bottom of said basin, as shown in Fig. 1. The periphery of the head of said plug is so formed that it shall form a lvertical cylindrical surface adjacent and 'tom of the reservior o and is fitted with a nut e1 by which theV basin is securely fastened 1n positlon upon the reservoir c.

Asetfscrew f1 may pass through the projection all into the plug f tohoid the latter firmly in position.

l f2, f2 are horizontal apertures formed through the plug f and registering with corresponding apertures through the projection d? so as to 'form a passage for the gasolene from the reservoir o.

t is a vert-ical passage from the aperture f2 having a valve seat at its upper end against which the end of a needle valve j is adapted to litto regulate the size of the opening through the passage t.

f* (Figs. 1 and 3) indicates vapertures formed horizontally through the plug f so as to open at their outer ends at the lower conical surface oi the head' of which isslightly raised from the bottom of the lbasin d. The passage t opens into the aperture f4.

cl2 is a flange extending outward from the top of the basin d, and restingr unon he upper edge of the reservoir o.

C1 is a hollow' cylindrical projection or extension from the top of the basin d.

C2, C3 are` cylindrical screw-threaded apertures adapted to receive conductor pipes, which apertures open through the wall of the cylindrical project-ion C1 opposite each other. It is a cylindrical shell fitting closely and adapted to turn in the projection- Cl and have opposite apertures f1.1, h2 through its wall, which apertures are adapted 'to register respectively with the openings from the apertures C2, C3.

7c isI a cover secured to the cylindrical projection C1 and adapted to'close the upper end of the same. I

h3 is a cylindrical stem extending troni a part z'y of the shell h through a corresponding.

aperture in the cover 7c.

m is a. handle secured to the out-er end of the stem h3 by which the shell it may be rotated in the projection C1. j
