SPECIFICATION-forming part of Letters Patent o. 288,622, dated November 20, 1883.

To @ZZ whom t may concern: Y

Be it known that y I, l CHARLES F. COPELAND, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Carburetors, of which the following is a specification.

Myinvention relates to that class of carburetors in which the carburetor-duid drops onto a helicoid, and slowly iiowing down` the surface ofthe helicoid meets air and gas, which is sent in at the lower end of the cylinder, so as to traverse the said helicoid in an upward Vdirection while the hydrocarbon liquid is iiowing downward; and it consistsin the combination of the evaporating device above de scribed with a steam-heating device and the thermostat-regulator. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of my invention. Fig. 2 is a horizontal section taken on line x y of Fig. 1. Fig. 3 is a vertical section enlarged, showing my automatic valve.

This invention is an improvement on the one granted to me March 20, 1883, No. 274,17 6.

A represents the cylinder inclosing my devices.

B B is a helicoid formed within the said cylinder, and so Aconstructed that its periphery may form an air-tight joint with the interior of the cylinder.

`N is the hydrocarbon-fluidsupply pipe.

The parts above referred to are fully `described in the above-mentioned Letters Patent.

I will now proceed to describe the parts of this device which I consider as new.

I? is an open steam-passage formed in the central part of the helicoid B B. low passage P, Fig. 1, is supplied with steam from the supply-pipe D.

E is a quill-valve. (Shown in detail in Fig.

3.) This quill-valve E has an opening, as Shown, which is normally at the end of the steam-pipe D, so as to admit of the freepassage of steam from the pipe D to the central opening, P, ofthe helicoidB B. This quill-valve E has a valve-stem, E', which passes through the stuffing-box K K', and ,terminates in a square shank, E2, said shank E2 being embraced by a boss, F, attached to the spiral thermostat L, so that any movement of the thermostat will causea corresponding movement of the quill-valve E. For convenience in adjusting the thermostat, I have a series of Screws, M M M, either one of which may be used to clamp a particular portion ofthe thermostat L onto the bracket C.

This hOl- The thermostat-coil consists of two strips of 6o 4 erate together substantially as described, and

for the purpose set forth.
