AUTOMATIC HYDROCARBON-FEEDING APPARATUS FOR C'ARBURETORS.

SPECIFICATION forming part of Letters Patent No. 308,877, dated December 9, 1884.

Application filed April 28, 1884. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES F; COPELAND, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Automatic Hydrocarbon- Feeding Apparatus for Carburetors and I do hereby declare that the same are fully describedin the following-specification and illus trated in the accompanying drawings.

This invention relates to improvements in automatic hydrocarbon-feeding apparatus for supplying hydrocarbon to gas machines or carburetors; and it is carried out as follows, reference beinghad to the accompanying drawings, where-- v Figure 1 represents an end View of the invention, and Fig. 2 represents a central longitudinal section on the line A Bin Fig. 1. Fig. 3 represents a cross-section on the line C D in Fig. 2, as seen from the right end of said Fig.

. 2; and Fig. i also represents a cross-section on the line C D, as seen from the left end of Fig.2.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

a is the cylinder, within which is located the rotary motor b, having the screw-shaped wing b, and arranged upon the central shaft or spindle, b, located in suitable bearings in the cylinder a, as usual.

0 is the gas-supply pipe leading to the motor I), and terminating within the latter as the upwardly-projecting pipe 0, as usual.

dis a branch pipe connected to the gas-supply pipe C in the ordinary manner, through which atmospheric air is forced with the gas into and through the motor I).

e represents the hydrocarbon within the cylinder or case a, such hydrocarbon being kept at a proper level above the motor-shaft b, as shown in Fig. 2, by a suitable float regulating device.

To one end of cylinder at is attached the box or chamber f, the upper portion of which is in open communication with the cylinder a by means of the opening a, made through the end of cylinder a where the box f is attached, as shown in Figs. 2 and 3, to allow the gas and air to pass from the cylinder at and its motor 1) into the upper part of the chamber f. The

lower part of said chamber f is in open communication with that part of cylinder a containing the hydrocarbon by means of the perforation f, (shown in Fig. 3,) so as to keep the hydrocarbon g in chamber f on a level with the hydrocarbon e in cylinder at in the ordinary manner.

h is the hydrocarbon-supply pipe leading to chamber f, and connected on the inside of the latter with a valve-box, 72., having valve h, delivery-opening h, valve-spindle If, hinged lever h, stationary fulcrum-support h, and

' float if, in the usual manner, for regulating the supply of hydrocarbon, and to retain its upper level at a normal one during the operation of the apparatus.

WVithin the box f is located upon the end of motor-spindle b the small pinion b ,that gears into the teeth of gear-wheel z, secured to the spindle i, that is free to move in suitable bean ings within the box f, as shown in Fig. 2.

To the spindle i is secured the disk, rim, or wheel k,having pivoted to its peripheral spindles 70 k the movable buckets 70" k, as shown in Figs. 2 and 4.

Above the spindle z" is secured to the wall of chamber f the spring-bar Z, (shown in Figs. 2 and 4,) that serves for the purpose of automatically tipping over each bucket 70" when it reaches its highest, or nearly so, position, and to deliver the hydrocarbon from such bucket into the trough an after it is taken up from the contents of chamber f, when such bucket passes through the liquid contents of said chamber, as represented insaid Figs. 2 and 4.

The trough m communicates with the downwardly-projecting pipe n, that leads to the car: buretor, and by this means a constant supply of hydrocarbon is taken up by the pivoted revolving buckets 7c", and delivered through the pipe at to the carburetor,where the gas or air is to be enriched. The upper end of pipe at opens into the upper portion of chamber f, so as to allow the gas and air forced from the motor 1) into said chamber to pass down through said pipe at with the hydrocarbon supplied from the buckets k 7a.

The operation of the apparatus is as follows: Air and gas being forced into the cylinder a by means of the pipes c d, and made to pass through the upper portion of motor 12, the latter is caused to rotate around its axis, and by spindle 12, wheel k, with its pivoted buckets means of the gears b i a rotary motion is im- 7c k, spring Z, trough'm, delivery-pipe n, hyparted to the wheel k, causing its pivoted drocarbon-supply pipe h,wit11 its valve h h, 15 buckets 7c 70 to dip into the hydrocarbon gin lever h and float h, all arranged and com- 5 box f, and to take up aportion of such hydrobined in a manner substantially as set forth carbon, and to empty it into the trough m as and described. the buckets successively come in contact with In testimony whereof I have affixed my sigthe tipping-spring Z, as described. nature in presence oftwo witnesses.

What I wish to secure by Letters Patent, and 1 CHARLES F. COPELAND. 10 claim, is Witnesses:

In combination, the cylinder a, rotary motor ALBAN ANDREN, b b, air and gas pipes c d, gears b i, box f, HENRY CHADBOURN.
