VAPOBIZER FOR- IFUEL HEATERS AND BUBNERS.

Application filed Eune 8, 1921. Serial No. 475,991.

T all whom it may concern:

Be it known that I, GEORGE PAUL KITTEL, a citizen of Germany, residing at Union Hill, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Vaporizers for Fuel Heaters and Burners, of which the following is a specification.

This invention relates to a novel fuel vaporizing attachment for laundry machines, stoves, boilers and similar fuel consuming apparatus to be used particularly in places where gas as a fuel cannot conveniently be used or obtained. 7 It is the principal object of the invention to provide a simple, yet efficient attachment of this character including means for preheating and vaporizing the. fuel before it is ignited to supply heat to any desired machine or apparatus where such heat is required.

Another object of the invention is the provision of a device of this type which can bereadily and conveniently attached to or removed from .any machine, stove or the like.

A further object of the invention is the provision of an attachment which is combined with means for overning minutely the quantity of vaporized fuel to be supplied to a burner, and of means for removing the products of condensation.

A still further object of the invention is to provide an attachment of this kind which is connected with a suitable source of electricity by means of which the fuel is vaporized while saturating a wick within the vaporizing cylinder and is preheated to a certain desired degree before it is fed to the burner.

With the foregoing and other objects in view, which will become more fully apparent as the description proceeds, the invention resides more particularly in the combination of elements, arrangement of parts and specific construction of details, as will be hereinafter more fully described and then specifically be pointed out in the apgended claims.

bviously, changes may be made in the precise combination and in the minor details of construction of the attachment herein disclosed without departing from the spirit and scope of the present invention. In the accompanying drawings, forming a material part of this disclosure, and in which my device is illustrated by way of example attached to a laundry machine Figure 1 is a diagrammatic rear view of an ironing machine, partly in section with the device constructed according to the present invention attached thereto.

Figure 2 is an end view of the machine with the device attached thereto in side elevation, the view being taken on line 2-2 of Flgure l.

Figure 3 is a detail view on an enlarged scale of the vaporizing cylinder in longitudinal section with the distributing valve and co-operating parts on top of said cylinder, partly in section.

Figure 4 is a detail view of a valve stem.

The ironing machine shown in the drawings to illustrate by way. ofvexample one way of using my invention, is of any approved type, and comprises ashere shown, a support or frame supporting in the customary well known manner, a roller'll for the articles to be ironed, as for instance shirts, and laterally disposed to said roller a smaller roller 12 for the ironing of collars or cuffs etc. is shown.

In front of the machine a'table 13 or the like is located for the reception of the ironed articles, and in rear thereof a pressing member 14 to which a pair of arms 15 are secured, the outer ends of which are connected by means of a hand lever 16.

A similar pressing member 12 is provided for the smaller roller 12.

A two-armed bracket 17 is attached to the lower edge of the member 14, and is ivotally secured at the meeting ends 0 said arms, as at 18, to the frame. To the lower arm of said bracket is attached the upper end of a depending rod 19 extendin through the table, and a spring 20 is coiled around the upper end or part of said-rod between the lower arm of said bracket and the upper face of the table.

The parts so far described do not form any part of my invention and are described on y for a better understanding of the same.

To one of the rear posts 21 of the frame 10 a tank 21 is attached, carrying a pump 22, an indicator dial 23, and a filler cap 24 on its top.

A- feed pipe 25 extends laterally from. the tank near its bottom, and is controlled by a valve 26. To the free end of said pipe 25 a flexible hose 27 is attached, the other end of which is attached to a bent nipple 28 at the lower end of a cylinder 29, closed at its lower end by a cap 30, and at its upper end by a cap 31.

A pipe 32 is attached to the upper end of i the nipple 28 and extends through the entire length of the cylinder into a valve box 33 screwed upon the upper end of said pipe 32 projecting through the cap 31 of the cylinder. Within the pipe 32 a wick 34: is provided,-ending below the u per end of said pipe which is closed by a wire netting 35.

A resistance coil 36 is wound around an inner cylinder 37 concentrically arranged within the outer cylinder 29 and surrounding pipe 32. The outer ends of the resist ance wires 38 and 39 are insulated from the coil by means of a mica sleeve 40 and a mica plate 41, and are insulated at their lower ends by the usual tape 42 and 413, and then formed into a cable 44 passing through the lower cap 30 of the cylinder 29 to an electric switch 45 of any well known type to which are secured in the well known manner the lead or conductor wires a6 and 47 leading to any suitable source of electric current.

Passing through the valve box 33 is a horizontally disposed valve stem as provided at one of its ends with a handle 49 and guided through nuts 50 and 51 having right and left hand interior screw threads respectively. The other end of the valve stem a8 is formed into a needle 52 adapted to engage a suitably shaped seat 53 formed in the end wall 54: of the box 33. This end wall 54 is formed with a central projection 55 to which is attached one end of a horizontal tube 56 provided near its end with a plurality of air openings 57. The opposite end of this tube 56 has attached thereto a knee or L-shaped sleeve 58, the upper end of which has a connection 59 secured thereto, which is connected to a horizontal pipe 60 arranged within the pressing member 1%, and provided with a plurality of burner openings in its upper face through which the gasified fuel escapes to be ignited for forming flames 61. To the lower end of the sleeve 58 a pipe member 62 is secured to extend downwardly, which carries at its lower end an exhaust cock 63 for the removal of the condensed part of the fuel or products of condensation.

From the L-sleeve a short pipe 64 is extending carrying at its outer, upwardly extending or irected end a small burner 65 having a wire mesh top and controlled by a valve 66. This burner is entered through a recess 67 into the pressing member 12 of roller 12,

The device operates as follows 7 Upon the opening of valve 26, the fuel will flow through pipe 25 and flexible tube 27 under the pressure prevailing in tank 21, into pipe 32 in which it is absorbed by the i ,aso,ase

in the valve chamber 33 from where they are fed in any desired quantity through the suitable regulation of the needle valve by means of its handle 49, into the tube 56 to be mixed with the necessary quantity of air entering through the openings 57 to be fed to the burners. The products of condensa-' tion which will collect at the bottom of tube 56 and sleeve 58 can be removed by the proper manipulation of cook 63.

Tt will be clear that the flexible tube 27 allows an operation of the pressing member it by means of its handle without disturbing the vaporizing process within cylinder 29 which will follow the movements of the pressing member on account of the flexible tube connection. a

The needle 52 is not only intended to regulate the flow of the vaporized fuel, but also to keep the small orifice of the seat 53 into which the needle enters, clear from any foreign matter that may accumulate within this orifice, so that the valve will be unobstructed at all times.

Having thus described my invention, what ll claim as new, and desire to secure by Letters Patent of the United States is 1.
