||v| PRovEMENi' IN yRECAULAi'ED VALVES` "FOR CARBURETERS.
Specification forming part of Letters Patent No. l 98,657, dated December 25, 1877; application `tiled December 8, 1877.
and it consists in the combination, ,with
the oil-tank of a carbureter, of a pipe extending downward from the bottom of said tank, and having its end curved upward, and terminating in a perforated valve-chamber, which opens upward beneath the bottom of .said tank, for emitting the liquid in spray,
and a valve-plug `fitting said valve-chamber, and reciprocated vertically to open or close the port or ports of said valve-chamber by means of a suitably-connected lever, which is pivoted to a stud depending from the bottom of the tank, and operated automatically by a float connected therewith, which` rises and falls with the changes of level of the liquid in the vaporizing chamber, whereby the jointed valve-operating parts are 4.located above and out of the way of the flow of oil, and thereby protected from liability to become corroded or gummed so as to impair. their efficient work- In the drawings, Figure l is a view, in elevation, of the invention. Fig.` 2 is a side view of the curved oil-pipe with the valve-chamber and plug; Fig.` 3 is a vertical section of the oil-pipe and valve-chamber, the valve-plug being shown in elevation.
The letter A represents the bottom of an oil-tank of a carbureter, and B is an oil-pipeprojecting downward therefrom, having its end curved upward, as shown at B', and terminating in a valve-chamber, C, opening upward, and having its bottom in the form `of an inverted frustum of a cone, and constituting the seat of the correspondingly-shaped end of a valve-plug, E', from which a shank, E,
extends upward, and is pivoted to the end of a lever, H, fulcrumed on a stud, K, projecting downward from the bottom A of the oil-tank. The other end of this lever is jointed to a rod,
L, which extends downward, and is intended to be attached to a iioat which rests upon the surface of the liquid ina vaporizing-chamber, within 'which all the parts described are inclosed, the bottom A of the oil-tauk forming the top wallof said chamber.
A short distance above the valve-seat the valve-chamber C is provided with a circumferential series of perforations, D, which are closed by the cylindrical plugE when the 'coned end ofv said plug is upon its seat, but
are open, and permit the outward flow of any liquid contained by pipe B when the cylindrical portion of the plug is raised above the lower edges of the perforations, the extent of flow of liquid being controlled by the height to which the plug is `raised between the bottom and top edges of saidperforations.
The operation of the invention is as follows: When the tank, the bottom of which is designated by A, is supplied with oil, the latter, of
course, iiows into the pipe B, and rises in the bent end, and, supposingl the vaporizing' chamber' to be empty, the ioat will be at its lowest point, and through the rod L and lever H cause the plug E to be raised and the perforations D opened, so that the oil in pipe B will ilow through said perforations into the vaporizing chamber, and as soon as it has ris en to proper level therein the iloat will have risen, and cause the plug lE to close' the perforations, and whenever, on account of vaporization, the oil falls below a proper level, the perforationswill again be opened, as will be readily understood.
, VBy the construction of the valvechambe with the series of small radial perforations the vaporization of the oil is greatly facilitated, V 4as the weight of the oil in the tanlr causes the Aoil in pipeB to flow through these perforations when open with such force as to project the line streams of o il to a considerable distance nearly horizontally from the valve-chamber, thus presenting to the warm air ofi the vaporizing-chamber a great extent of oil-surface,-
operation of the apparatus is very reliable, as the parts having Working joints are so arranged as to be out of the Way of the oil iowing from the valve-chamber, and are, therefore7 not liable to corrosion or gumminess, which would prevent their prompt action at the proper time.
What I claim as my invention is- The combination, with the oil-tank and vaporizing-chamber of a carbureter, of a pipe extending downward from the bottom of said tank, and'having its end curved upward7 and ,terminating in a'perforated valve-chamber,V
which opens upward beneath the bottom of said tank, for emitting the liquid in spray, a valve-plug tting said valve-chamber, a lever and suitablyconnected iioat7 wherebyr the valve is opened and closed with the variations of the level of the liquid in the vaporizingchamber7 substantially as described.
