JAMES ll. BULLARD, OF SPRINGFIELD, MASSA(lllUSETTS.

APPARATUS FOR BURNING HYDROCARBONS.

SPECIFICATION forming part of Letters Patent N0. 397,337, dated February 5, 1889.

Application filed December 21, 1887, Serial No. 258,580. (No model.)

To all whom 7'25 may concern.-

Be it known that 1, JAMES ll. BULLARD, a citizen of the United Stat es, residing at Springfield, in the county of Ilampden and State of Massachusetts, have invented new and useful Improvements in Apparatus for Burning Hydrocarbons, of which the followingis a specification.

This invention relates to an apparatus for securing and regulating the combustion of liquid fuel in connection with suitable furnaces, and particularly to one in and by which airis introduced to theburner in conjunction with the hydrocarbon, the object whereof being especially to secure a controlling and regulation of the air-supply to said burner; and it consists in the combination and arrangement of the various parts of the apparatus, all substantially as will be hereinafter more fully described, and set forth in the claims.

In the accompanying sheet of drawings, Figure 1 represents the apparatus of the present invention inpartial side elevation and central vertical section as applied in relation to a" glass-heating furnace and its glass-melting crucible, and Fig. 2 is a plan view of Fig. 1.

In the drawings, A represents a burner of any suitable shape, in the present instance of a form especially applicable for use in relation to a glass-heating furnace, B, and the melting vessel or crucible C, and shown as consisting of a circular casing or chamber, perforated at its upper side and being provided at its under side with asuitable fitting, 0, with which an oil-supply pipe, D, leading from a suitable oil-tank, E, is connected, said oil-pipe at an intermediate port-ion thereof being provided with a cock, .(I, for regulating the passage and supply of the oil tothe burner.

F represents an air-pu mp, of any desirable construction, provided with a reciprocating piston-rod, l), and mechanism is provided for operating said air-pump, (here shown as consisting of a main shaft, G, driven by belt ll and pulley J, a counter-shaft, K, arrange'l parallel with said driving-shal'ft, and cone-pulleys G K fixed on said shafts, connected by a belt, B, said co un ter-sl 1 al't being provided with a crank, I connected by a pitman-rod with the piston-rod of the air-pump.)

H represents an air-pipe leading from said air-pump to and connected with the burner A at its fitting c, and at an intermediate position of said air-pipe M is located and secured a pressure-regulator, N, the main chamher 0 of which is in communication with the air-pipe M, a reciprocating piston, P, playing vertically therein, with and against a spiral spring, Q, its piston-rod I being upwardly projected.

T represents a shaftarranged between and slightly above the shafts G K, adapted to slide longitudinally in suitable bearings, (I,- therefor, having secured thereon downwardly-ey tended branched arms f f, embracing the transverse belt between the cone-pulleys.

A bell-crank lever, U, hung in suitable bearings therefor, is interposed between one end of said belt-shifting shaft T and the outer end of said regulator piston-rod. Under the rotation of the driving-shaft and the consequent operation of the air-pump, should the air-supply and pressure thereof from said pump to the burner be too great for proper combustion and sufficient to raise the piston of the regulator against its spring properly adjusted therefor, through the bell-crank lever, the belt-shifter is moved to carry the belt to a position on the cone-pulley of the driving-shaft of less circumference, and to a position on the cone-pulley of the counter-shaft of greater circun'iference, thereby retarding the operation of the pump-plunger and diminishing the air-pressure, all as is plain.

\Vhile a particulararrangement of belt and pulleys and of abelt-shil'tingdevice has been. particularly shown and. described, the invention is not to be limited thereto, as other forms of belts and pulleys and of. belt-shifting devices t-hcret'or maybe employed, if desired, in conjunction with an air-pump and in relation to and to be ettocted by the reciprocating piston-rod of the regulator for the air-pipe.

\Vhat I claim as my invention is" 1. An a i paratus for securing and regulating the combustion of liquid fuel, comprising a hydrocarbon-burn'er, a liquid-fuel tank, a pipe connecting said tank and burner, an airpump, a driving-shaft, and intervening movable driving-connect-ions between said drivingshaft and said air-pump eapable of variable speed, a pipe connecting said air-pump and burner, and a regulator in eonnnnnication with said air-pipe having a reei irooz'tting piston-rod, and a eonneetion between said regulator pistoi'i-rod and said movable drivingeonneetions between said driving-shalt and air-pun substantially as and tor the purpose described.

:2. An appz'tratus for securing; and regulating' the combustion of liquid fuel, comprising a, hydrooarl)on-lmrner, a liquid-fuel tank, a pipe connecting said tank and bu rnor, an airpump, a driving-shaft providml with a conepulley, a counter-shaft connectwl with said air-pnn'lp, having a cone-pulley, a belt connecting said cone-pi'illevs, a pipe eonneeting said air-pump and burner, and a regulator in eonininnication with said air-pipe, having a reciprocating piston-rod, an d a conneet ion botween said regulator piston-rod and the belt 1 connecting said eonepnlleys, sul)stantiallflis 4 and for the purpose tlfSCl'lbPti. l

1. An apparatus for securing and regulating the (OlllllllSillOl'l of liquid fuel, comprising a liydrooarboi1-burner, a liquid-t'nel tank, a pipe (eonneeting said tank and burner, an airpump, a driving-shaft provided with a conepulley, a oountenshati't connected with said air-fnunp, having a voile-pulley, a belt eonneeting' said eonepulleys, and a: shaft, T, eapable of sliding:longitudinally, provided with the bolt einbraein;- and shifting arms f j; a pipe connecting said ai1" )uin1) and burner, and a regulator in eoinninnieation with said ai r-pipe, havin a reeiproeati ng piston-rod, P", and a pivoted bell-crank lever by its one end engaging said regulator piston-rod and byits other end engaging said sliding shaft '1, substantially as and for the purpose described.
