EATER FOR APPLYING AND MELTING WAXES, PARAFFINS, SOLDERS, AND SIMILAR l SUBSTANCES.

Specification of Letters Patent.

Patented Sept. 1, 1908.]

To all whom it may concern:

. Be it known that I, FRANK A. REILLEY, a citizen of the United States, residing in the village of Port Chester, in the county of Westchester, State of New York, have invented a new-and useful heater for melting and applying waxes, paraffins, solders, and similar substances, which heater will hereinafter be designated as a waX melting and applying machine, of which the following is a specification.

This invention relates to a device for melt ing and applying wax, paraffin and the like, and relates more particularly to a device of that type in which the heat is furnished by a current of electricity traversing coils or heat ing units suitably arranged on the vessel or crucible that holds the wax, paraffin or the like. V

The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively easy and inexpensive to manufacture, thoroughly reliable and efficient in use, and readily manipulated.

A further object "of the invention is the provision of a vessel of suitable design on which are permanently arranged heating units or coils for melting the wax or parafiin by heat transmitted through the walls of the vessel, the flow of current through the coils being controlled by a switch arranged on the handle of the vessel so that different degrees of heat can be obtained, if desired.

Another object of the invention is the employment, in connection with a device of this character, of a valve for controlling the discharge of melted wax or paraflin, the valve being operated by a lever mounted in such a iosition that it can be conveniently actuated by the same hand whichholds the handle of the device.

With these object in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hercinaftcr and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illus trates one of the embodiments of the invention, Figure 1 is a central vertical section taken through the vessel or crucible with parts of the device in elevation. Fig. 2 is a side viewof the device with a portion of the handle broken away.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawings, A designates a stand for holding the device during the mounting operation or when-the device is not in use, the stand consisting of a ring 1 and legs 2 rigidly secured to the ring.

The device consists of a vessel or crucible B which is open at its top and of cylindrical form at its upper portion 3 and tapers downwardly-into a funnel portion 4. The funnel is contracted at 5 to form a seat 6 and below the seat is a discharge mouth 7 throughwhich the melted wax, paraffin or thelike is delivered. Disposed around the tapering or conical portion of the crucible. or vessel B are heating units 8 and 9 constructed of coils of suitable wire and fixedly secured in position by a suitable insulating binding. These windings are suitably connected in series so that current can be passed through both of them when it is desired to obtain the lower degree of heat and one of the windings can be cut out when it is desired to obtain a higher degree of heat.

Attached to the crucible B is a handleC which carries at its inner end a switch device designated generally by D. This device comprises contacts 10 and 11 with which cooperates a contact lever 12 pivotedat 13 on the plate 14, the lever and contacts being suitably insulated from the said plate. The plate, which may be of insulation, is secured to the handle C by screws or other fastenings 15. The handle C is preferably hollow for receiving the lead-in wires 16 and 17 which are intended to be connected with a suitable supply circuit by a socket plug (not shown), and the inner ends of the wires are connected respectively, with'the screw or pivot 13 of the lever 12 and the binding post 18 on the plate 14. The switch device is connected with the heat coils by the wires 19, 20 and 21. The wire 19 connects the inner coil 9 with the binding post 18 and the wire 21 connects the outer coil 8 with the contact point 11, while the wire 20 connects the contact point 10 with an intermediate point of the wire 01 2 10c .or heating unit 9.

it can be moved. back and forth by means of the thumb of the hand grz'isping the handle 0 of the device. When the lever is in engagement with the contact 11, the current will. pass through the wire 16, lever 12, contact 11, wire 21, both coils 8 and 9, wire 19, bind* ing post 18, and wire 17. Since both resist-- ance or heating coils are in circuit, less current will pass and conse uently the lower heat will be obtained. to obtain a higher heat, the lever 12 is moved into engagement with the contact so that the current will traverse only the inner coil Arranged within the crucible is a valve 23 of suitable form that is carried on the lower end of astein 24 which projects out of the crucible at the top, where the stem is hingedly connected at 25- With the front end of an actuating lever 26. This lever is fulcrumed at .Zfion'the inner end of the handle and the rear end is formed into a thumb piece 28, whereby the operator can depress the lever to unseat the valve when it is desired to permit some of the melted paralfiu or waxto discharge from the mouth 7,. The parts are so arranged that the valve will tend to gravitate to its seat but it may be desirable to provide positive means for seating the valve, such as a spring 29 secured to the handle -30 with one end pressing on thethumb piece 28 so as to operate through the lever and valve stem to hold'the valve against its seat. I v

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be parent to-those skilled in the art to which the invention 'appertains, and while scribed the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative,

hen it is desired readily ap- I have d e-I and that such changes may be made when desired as are within the scope of the claims.

Having thus describedthe invention, what I claim is 1. In device of the class described, the combination of a crucible open at its top and provided with a discharge mouth at its bottom, a seat at the mouth, a valve arranged to engage the seat, a stem rigidly connected with the valve and supporting the same, a handle connected. with the crucible adjacent the top thereof, a lever connected with the upper end of the valve stem, means for fulcruining the lever on the inner end of the handle andabove the latter, a finger'piece on I 'the outer end. of the lever and projecting over the handle, and a spring secured to the handle and bearing on the lever to hold the valve seated, with a switch mounted on. the handle at the side thereof, and a heating coil on the crucible and controlled by the switch.

"2. ins device of the class described, the combination of a crucible tapering downwardly to form a contracted mouth, a valve seat at the mouth, a valve arranged to engage the seat, a stem connected with the valve, a hollow handle attached to the cruel ble, a bracket on the inner end of the handle a lever pivoted intermediate its ends on the bracket, a hinge connection between one end of the lever and the upper end of the stem, the opposite end of the lever projecting over the handle, a sectionalized heating .coil secured around the outside of the crucible, and a switch-device mounted onthe handle and comprising contact point-s,connected'to dif.

ferent parts of the heating coil, a lever movable into and out of contact with the points,

a lead wire connected with the switch lever, and a wire connected with one end of the coil.
