3 Claims.

This invention relates to new and useful improvements in electrical heating devices and the primary object of the present invention is to provide a portable heater for electricians solder dippers.

Another important object of the present invention is to provide a solder dipper heater including a heating chamber, a dipper receiving bowl and embodying novel and improved means for heating the bowl for effectively and efficiently melting solder placed in a dipper that is retained in the bowl.

A further object of the present invention is to provide a solder dipper heater including a means for holding a dipper in position to the electrically heated dipper receiving bowl carried by the heater so that the dipper may be quickly and readily removed in a convenient and safe manner for use.

A still further aim of the present invention is to provide an electricians solder dipper holder and heater that is simple and practical in construction, strong and reliable in use, small and compact in structure, neat and attractive in appearance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan View of the present invention and showing a dipper applied thereto;

Figure 2 is a longitudinal vertical sectional view taken substantially on the plane of section line 22 of Figure l; and,

Figure 3 is a view showing the heating element used in conjunction with the present invention, partly in elevation and partly in section.

Referring now to the drawings in detail, wherein for the p rpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I9 represents the base of the instant construction having a reduced upper end 12 that receives a cylindrical shield M, defining a heating chamber I6.

Fasteners l8 extend through the shield l4 and into the portion l2 to retain the said shield in position to the base.

The lower surface of the base I e is provided with a recess 29 that receives the upper end portions, of a plurality of circumferentially spaced supporting feet or lugs 22 of preferably hard fiber material. The feet support the base in an elevated position with respect to a supporting structural element so that air may pass under the base, into the recess 28, through a vertical bore 26 formed in the base and hence into the heating chamber !S. The feet 22 are detachably secured to the base Id by bolts and nuts or like fasteners 26.

The numeral 28 represents a refractory clay or porcelain cup or bowl having a tapered or frustoconical lower portion 30. The portion 39 includes a lower wall 32 that bears upon the upper surface of the portion I2 and the wall 32 receives a fastener 34 that extends into the portion l2 for holding the bowl relative to the base.

The outer periphery of the bowl 23 is provided with a plurality of recesses 35 that receive heating wires or coils 38 of preferable nickelchrome alloy. The coils 38 are connected together and to circuit wires Ail, and the wires 453 as well as the insulated covering 42 for the wires 40 extend through a passage 44 provided in the base and to a suitable source of electric current.

A plurality of openings 45 are formed in the bowl 2!; and these openings communicate with and intersect the reces es 36 so that heat from the coils 38 will pass through the openings 46 and into the interior of the bowl.

Mounted in the upper end of the sh eld I4 is a diametrically disposed combined b fiie and support plate 653 having downturned ends 50 that are secured to the walls of the shield by fixtures 52. The central enlarged portion of the plate 48 is provided with an opening and the edges defining this opening are turned downwardly as at 54 to yieldingly grip the upper edge of the bowl 28 thereby supporting the bowl and preventing endwise movement thereof.

Secured to the shield M by one of the fasteners 52, is the angulated end port on 55 of an upwardly and outwardly proiecting arm 58 that is fixed to one end of a handle or hand grip 59. The lower end of the hand grip is secured to a brace arm 62 that is removably carried by the base H3.

The free outer end of the arm 53 is turned upwardl and is notched as at B4 to receive the shank 56 of a dipper having a cup 68 that is positioned in the bowl 28.

In view of the foregoing description taken in conjunction with the accompanying drawing it is believed that a clear understanding of the device will be quite apparent to those skilled in this art.

A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. An electric heating device comprising a base, supporting feet carried by the base, a shield rising from the base and being hollow to define 'a heating chamber, a combined bafiie, guard and support mounted in said chamber, a bowl disposed in said chamber and detachably secured to said base, means for heating said bowl includin an electric heating wire embracing said bowl, and means for supporting a dipper in said bowl, said combined baflie, guard and support having an opening therein in registry with said bowl, the edges defining said opening being turned downwardly and positioned in said bowl, said bowl including a plurality of annular recesses in its outer periphery receiving said heating wire, said bowl also having a plurality of openings intersecting said recesses and providing heat passages.

'2. An electric heating device comprising a base, a cylindrical shield rising from the base, a hollow bowl supported on the base and having an upper open end, an elongated member disposed diametrically of said shield and terminally secured to said shield, said member having an opening therein in registry with said bowl, a flanged portion at the edge defining said opening and received in the upper open end of said bowl, means .for heating the bowl, said member constituting a shield, a baffie and -a support, and means for supporting a-dipper in said bowl, said supporting means including a vertically inclined arm attached to said shield and having a notch lug at one end, a hand grip depending from said arm,

and a brace arm securing the hand grip to the base.

3. An electric heating device comprising a base, a cylindrical shield rising from the base and being hollow to define a heating chamber, a cylindrical bowl disposed within said chamber and axially of said cylindrical shield, an electric heating wire embracing said bowl, said bowl including a plurality of annular recesses in its outer periphery receivin said heating wire, said bowl also having a plurality of radial openings intersecting said recesses and providing heat passages, said bowl including an inwardly tapered lower end secured to said base, and means supporting the bowl centrally of and within the chamber said means including a plate attached to and disposed diametrically of said shield, said plate having a central opening in registry with said bowl and a continuous flange depending from said plate about said central opening and received in the upper end of said bowl.
