BARREL- HEATER.

SPECIFICATION forming part of Letters Patent No. 745,432, dated December 1, 1903.

Application filed April 4, 1903. Serial No. 151,167. (lilo model.)

To 0.0% whom it may concern:

Be it known that I, ALFORD ALVIN Gornv, a citizen of the United States, residing at Gladerun, in the county of Vfarren and State of Pennsylvania, have invented a new and useful Barrel-Heater, of which the following is a specification.

This invention is an improved barrel-heating device, the object being to provide a simple and highly-efficient construction of barrel-heater which is so constructed that in opera-ting the same it will not be necessary to lift the barrels over the burner when placing or removing the barrels.

Another object of the invention is to pro.- vide a heater using gas and one which will automatically operate to out the gas off and on as required, thereby economizing in the use of the gas, inasmuch as it is only consumed to any considerable extent when the barrel is being heated.

A still further object is to provide a barrelheater in which the operation of asingle lever will be sufficient to effect the operation of all the other various parts of the apparatus.

With these objects in view my invention consists, essentially, in the employment of a bed-plate having an opening in the bottom thereof, a burner located beneath the bedplate and adapted to be projected through the opening therein, a case arranged beneath thebed-plate and in which the swinging burner moves, an igniter arranged in connec-' tion with the said case by means of which the burner is lighted as it passes upwardly through the opening in the bed-plate, a hood arranged upon the bed-plate and within which the barrel to be heated is placed, said hood having a door at the forward side thereof, 7 together with means for raising and lowering of a barrel-heater constructed in accordance with my invention. Fig. 2 is a vertical sectional view of the heater, the door-operating mechanism being omitted. Fig. 3 is a horiing A adjacent the elongated opening A zontal sectional view on the line 3 3 of Fig.2. I Fig. 4. is a detail sectionalview taken through a port-ion of the upper end of the hood. Fig. 5 is a detail View, partly in plan and partly in section, showing the manner of arranging the doors at the front of the hood and jacket. Fig. 6 is a detail plan View, partly in section, showing themanner of arranging the burner and pipe, the igniter, and the manner of connecting the burner and igniter pipes to the gas-supply pipe and also the case for containing the burner when not in operation. Fig. 7 is a detail perspective view showing the arrangement of the valves for controlling the gas-supply. Figs. 8 and 9 are detail sectional views of the igniter and burner valves, respectively. FigqlO is a detail view illustrating the sliding plate through which the burner-pipe passes and which closes the rear end of the case for the said burner.

In constructing a barrel-heater in accordance with my invention I employ a bed-plate A, which has an elongated opening A produced therein and also a small circular open- A hoodB is arranged upon the bed-plate and is of such size that the barrel to be heated can be conveniently located therein, and when the barrel is arranged within the hood and rests upon the bed-plate it will en compass the openings A and A as most clearly shown in Fig. 2, and it will of course be understood that at the time the barrel is heated it is open at one or both ends. The hood B is open at the front and'is provided with a verticallysliding door 13, said door sliding between the upright guiding-standards Biwhich are connected to the forward corners of the hood and extendaconsiderable distanceabovethesame. If desired, a jacket 0 may be arranged within the hood depending from the top thereof, and when such jacket is employed in connection with the hood it also is provided with an upwardly-sliding door 0, suitable guidingstandards being arranged adjacent and in'parallel relation to the standards 13*, and the sliding bars B and C'are connected by means of a strip 0 which 7 eifectively. closes the hood when the doors are lowered, said stripbeing of sufficient width to engage the top of the hood, as most clearly shown in Figs. 2 and 5.

This strip also forms the connecting means between the doors B and C, so that when one door is raised the other door will raise also and likewise when lowering.

The doors are raised by means of a cable D, which passes over a pulley D, journaled in a bracket D arranged upon the cross-piece D connecting the guiding-standards, and the other end of the cable is connected to the lever E, pivoted between the upright rods E, which are connected to the bed-plate at the rear of the hood, and the rear end of the lever is pivotally connected to a link-rod F, the lower end of which is connected to a crank-arm G, carried by a rock-shaft H, which. is journaled in bearings H, connected to the bed-plate. An-

other crank-arm I is mounted upon the end of the rock-shaft H, said crank-arm having a pull-lever K connected thereto, said lever resting upon a pin K and projecting upwardly and forwardly within convenient reach of the operator, the forward end being shaped into a suitable handle .or grip K By pushing down on the lever K the rock-shaft H is turned, throwing the crank-arm G upwardly, which movement forces the forward end of the lever downwardly, thereby pulling upon the cable D and raising the doors 1% and O.

The lever E is provided with a weight E to assist in this operation, said weight being adjustable. Vhen the doors are raised, the barrel to be heated is placed within the hood, and by reversing the movement of the rod or lever K the doors are closed.

A socket L is rigidly connected to the rockshaft H and in which is fitted the burner-pipe M, said pipe having an elbow-joint M, and a burner hi is arranged at the extreme end of the pipe. The pipe is of such length that the upwardly-extending end carrying the burner can be projected through the elongated opening A up into the barrel when the doors of the hood and jacket have been closed,and by connecting the burner-pipe to the rockshaft H these movements are made simultaneously with the operation of said doors.

N indicates a gaspipe, which is bent at N to permit the movement of the burner-pipe, and the said burner-pipe and gas-pipe are connected by means of a flexible pipe 0, which leads from a valve 0, arranged upon the gaspipe and operated by means of an arm 0 to which is connected a link 0 which link in turn is connected to an angular lever O, rigidly mounted upon the rock-shaft H, so that when said rock-shaft is operated for the purpose of closing the doors and raising the burner the valve 0, controlling the supply of gas to the burner-pipe, will be opened and will be closed when the reverse operations take place. A casing P is arranged directly beneath the bed-plate and is made, essentially, V-shaped for the purpose of accommodating the burner and pipe when they are withdrawn from the barrel and hood. This casing is closed on all sides in order to prevent air pass ing upwardly into the heater, and at the rear end, where the burner-pipe passes through, I provide a sliding plate P, having an opening P through which the burner-pipe passes, and this plate slides in guides P formed upon the casing, and-the plate is of such length that it will ettectively close the rear end of the easing when the burner is in either a raised or lowered position. .A small air-inlet P regulated by a damper, is made in one side of the casing. An igniter-pipe Q has its forward end projected into the casing, projected be low the elongated opening Ain the bed-plate and in close proximity to the path of the burner in its upward flight, the purpose of said igniter being to supply the necessary light for lighting the burner as it is moved upwardly into the barrel and hood.

The igniter-pipe Q is connected to the valve Q, which is in communication with the gassupply pipe N and is operated by an arm Q link (23, and angle-lever Q said angle-lever being rigidly connected to the rock-shaft H. The valves Q and O are so constructed with reference to each other that when the shaft H is rocked one valve will be open and the other closed, according to the movement of the said rock-shaft, and when the burner is in its lower position, as shownin dotted lines in Fig. 2, the valve 0 is closed and the valve Q open, so that the igniter is burning and the burner extinguished. As the burner moves upwardly, however, the valve 0 opens, gas is supplied to the burner, and in passing close to the ig- I niter the burner becomes lighted and passes upwardly into the hood in the lighted condition, and the igniterwalve Q is then closed and is not opened again until the burner descends. By means of this construction the use of gas is economized, as no considerable quantity of gas is consumed except when the burner is in operation and used for heating the barrels.

An opening A is produced in the top of the hood adjacent the center, and the sliding dam per A is adjustable over said opening for the purpose of regulating the escape of gas and products of combustion. Additional openings A are produced in the top of the hood.

adjacent the edges and through which the gas and products of combustion can escape when the damper A is closed. The jacket 0 within the hood is not essential and may be dispensed with, if so desired. openings M adjacent the rear ends to permit air to enter for the purpose of producing more perfect combustion and a greater heat.

In operation the doors are raised by pushing upon the rod or lever K, and simultaneous with this operation is the lowering of the burner. The barrel is then placed upon the bed-plate over the openings, and by pulling upon the rod the doors are closed and the burner projected upwardly into the barrel to be heated, and as the said burner passes the igniter it will be lighted, as heretofore described. All of the minor operations of my invention The burner-pipe N has have been fully described, and further description is not deemed necessary.
