Application AprilZl, 1950, Serial No. 157,333
' 4 Claims. (01. 21919) My invention relates to improvements in heating devices and more particularly to a device for heating the depending ends of individual portable attaching elements. r
The object of my invention is to provide a device thatis equippedwith an adaptor slot for retaining specially designed attaching elements in proper position while heating them.
Another object of my invention is to provide a device of the character described that will accommodate a plurality of individual attaching elements, or a single holder that is equipped with properly spaced elements.
Another objector my invention is to provide a device that permits regulation of the temperature for the proper heating of the attaching elements.
A still further object of my invention is to provide a device that is portable, easily transported and accessible for use wherever electric current is available.
In the process of applying photographic film to masks or holders for projecting purposes, it is common practice to adherently attach the film to the gummed surface of the mask, and the device described herein facilitates a means of heating the depending contact surfaces of the attaching elements employed for the purposes of adherently attaching the film to the gummed surface of the mask by means of heat.
Other and further objects of my invention will become more apparent as the description proceeds and when taken in conjunction with the drawings in which Figure 1 is a perspective view of the device with an attaching element in position within the elongated adapter slot.
Figure 2 is a cross-sectional view of the device as shown in Figure 1, showing the attaching element in position within the adapter slot.
Figure 3 is a side view of the attaching element, and
Figure 4 is a diagrammatic design of the current conveying circuit for energizing the heating element.
Similar characters of reference indicate corresponding parts throughout the several views and referring now to the same, the character I shows an enclosure which is shown of rectangular construction. It may be of any shape or contour and is shown provided with leg portions I I to raise the open end of the enclosure from the surface to which it is applied.
The upper face of the enclosure I 0 is shown equipped with an elongated adapter slot I2 which extends longitudinally along the top of the enclo-. sure. There are ventilating slots I3 shown dis; posed through the wall of the enclosure to permit air circulation within the enclosure, while the heating element I4 is heated by means of electric current. There is a heating plate I5 which sup ports a heating block I6. This heating plate I5, and the block I6 are suspended below the adapter slot I2 and are provided with a conventional rheostat shown as I"! which has a control knob shown as I8 extending outward from the wall of the enclosure for regulating the amount of current conveyed to the heating element, thereby controlling the temperature of the heating block,
I6. There are bolts I9 shown supporting the heating element to the plate I5 and the screws 20 support the entire unit to the top of the enclosure ID. Obviously, the plate I5 and the block I6 are of a length corresponding with the slot I 2 through the top of the enclosure.
A current supply lead shown as 2| leads from the source of current and provides a circuit by means of the cord 22 leading to the rheostat, and a cord 23 leading from the rheostat to a post 24 on the heating element I4, and from another post 25 on the heating element I4 a cord 26 extends to the current conveying means 2I.
The attaching element to be heated shown in Figure 3 as 2'! has a metallic plate portion 28 and a plastic grip portion 29, and the screws 30 are employed to support the plate 28 to the grip portion 29. The attaching element 21 is of a design to fit within the adapter slot I2 of the enclosure II] and the face 32 of the element 2! rests onto the block I6, whereby the radiated heat of the block I6 is conveyed to the element 21. In the drawing, I show a single attaching element 21. This may be of a length to correspond with the slot 20, or a plurality of shorter elements 27 equipped with grip portions 29 may be inserted into the slot 20 and thereby contact the block I8 all at one time.
Obviously the cord 2| passes through the wall of the enclosure and is insulated therefrom by means of the insulator cushion shown as 3 I.
In the chosen embodiments of my invention there are many features not heretofore disclosed in the prior art, and although I have shown a specific arrangement of the component parts constituting the device, I am fully cognizant of the fact that many changes in their form and configuration may be made without effecting their operativeness, and I reserve the right to make such changes without departing from the spirit of my invention or the scope of the appended 2. A device of the character described comprising in combination an enclosure, an elongated adapter slot disposed longitudinally through the top of said enclosure, ventilating apertures disposed through the side walls of said enclosure near the top and bottom thereof, a heating block supported within said enclosure at a point below said slot, a heating element attached to said block, and current conveying means to permit energiz ing said heating element when current is applied.
3. A device of the character described comprising in combination, an enclosure, an elongate-d adapter slot disposed longitudinally through the top of said enclosure, ventilating apertures through the side walls of said enclosure near, the top and bottom thereof, a heating element, a heating block, said heating block disposed above said heating element, said block and heating element sup-ported within said enclosure, said block extending longitudinally below said elongated adapter slot, and current conveying means 4 to permit energizing said heating element when current is applied.
4. A device of the character described comprising in combination an enclosure, an elongated adapter-slot disposed longitudinally through the top walls of said enclosure, apertures extending through the side Walls of said enclosure near the top and bottom thereof for permitting air circulation Within said enclosure, a heating element, a heating block disposed above said heating element, said block and heating element attached to one another and supported within said enclosure, said block extending below said elongated adapter slot, .a current conveying means for energizing said heating element when current is applied, and a rheostat disposed within said enclosure and forming a part of the current conveying circuit for regulating the temperature of said heating element.
