ELECTRIG APPARATUS FOR vSECURING BASIC WAX SHEETS TO THE WIRES OF HSONEYGOMB FRAMES. FOR BEE- The present invention relates to-the production of honeycombs for beehives. It is an object of the invention to provide means contributing to an improved electric apparatus permitting in an eflicient and simple manner securement of the usual wax sheets to the wires of honeycomb frames.

Heretofore, different systems have been used for securing in position the basic wax sheets in honeycomb frames as,for example, by mechanical pressure with the aid of adequately shaped rollers, by insertion of the sheet within a narrow space left between two rows of wires; or by electrically heating the wire, although this latter system has frequently involved the risk of partially destroying the wax sheet at the slightestnegligence of, the operator.

Besides, up to the present no system has been known permitting said wax sheets of being secured in position in an efiicient manner and without undue inconvenience.

Another object of the present invention is to provide means; affording securing. in place of said wax sheets in a most simple and safe. manner, by incorporating the frame wires in the wax body without any risk of cutting or otherwise damaging the wax sheet.

With the apparatus according to the invention it is possible to heat the wires of a honeycomb frame before they are, placed in contact with the wax sheet, thus controlling the correct temperature required for softening the wax material exactly toa point where the wire may become incorporated in the body of the wax sheet without damaging the latter.

The present apparatus. is further characterised by the provision of certain novel. elements, such as, means for opening or closing the heating circuit through the honeycomb frame proper; a slidable supporting platform and possibility of modifying its width in accordance with difference in size of the frames, and other features which will become apparent as the following description proceeds, which should be read in conjunction with the accompanying drawing, wherei Fig. 1 is a side view of an apparatus embodying the invention, parts being broken away;

Fig. 2 is a top plan view thereof;

Fig. 3 is a view taken from the rear end of the apparatus;

Fig. 4 is a cross-sectional view on line A--B;

Fig. 5 is a further cross-sectional view on line C-D of Fig. 1.

The construction illustrated in the drawing comprises a platform I at one end of which is mounted a rheostat 2 having a resistor 2a (Fig. 2) which may be supplied with electric current from any adequate source through one of the wires and 3, 3'. Since resistor 2a must be connected. in series, it is joined to selector handle 2b which is electrically connected to the resilient contact 4a of interrupter 4, Whereas the other contact 4b is connected directly to wire 3'.

If the resistor 2a is of the fixed type, selector handle 212 may be dispensed with, the connection then being made from anypoint desired to a contact of interrupter 4, in accordance with the fall of tension as required.

Interrupter 4 has two further contacts 5a. and

5b, opposing respectively contacts 4a and 4b,'

these contacts. being in the form of clips arranged at the ends of a bar 5. At least onev of these clip contacts has a different length from the other, so as to permit of arranging the longer clip contact. member either to the inner or to the V outer side (as indicated in full and dotted lines in Fig. 2) by reversing the positions of clips 5a, 5b with respect to bar 5 so as to permit the application of frames of lesser width where the projecting ends of the wire b for contact with said clips 5a, 5b. are located at a corresponding shorter distance between them.

The. bar 5 is shiftable on platform I, to which end at its, medial portion a spring 6 is provided so as to establish contact with the corresponding wall 20 of the casing or edge of rheostat 2.

A small bolt 1 freely projecting through said wall 20 (Figs. 2 and 4) serves to maintain the parts incorrect operating relationship.

On platform. I is loosely supported a board 8. having at, its sides. flanges 9 serving as guides. At a longitudinal zone of said board 8 there is slidably mounted a separable member ID (Figs. 1, 3 and 5) so as to permit the use of the device in connection with honeycomb frames of lesser width which are used in certain types of beehives.

When the present device is used in connection with frames of standard dimensions, the latter are placed on the slidable board 8 so that their end and side members extend downwardly along the ends and sides of board 8 with the wire b resting on the wax foundation placed on top of said board, terminals d being in a plane parallel to the plane of the board. When using the device in connection with frames of lesser width, one side member thereof would remain resting on top of board 8 with terminals d out of alignment with contact clips 5a, 5b. Therefore, in

such a case, the slidable member I is longitudinally withdrawn from its seat, thus providing in the board 8 a guide groove adapted to receive the corresponding side member of the frame and permitting terminals d to be aligned and on level with clips a, 5b.

The operation of the device is as follows:

Figs. 1, 2 and 5 illustrate a frame a on which is mounted a wire b and a basic wax sheet c which is to be secured to the wire 1). It is to be noted that the terminals or free ends at of said wire project slightly beyond one of the ends or head members of the frame a.

In order to carry out the operation for uniting the wax sheet 0 to the wire b, the frame a is placed on the board 6 and this assembled unit is slid along on platform I, with the ends or terminals d of wire b in contact with contact clips or members 5a, 5b which, as aforesaid, are arranged on the movable bar 5. Thereafter, the latter with the frame a is pushed along until said clip contact members 5a, 5b encounter contacts la and 4b, thereby closing the electric circuit Whereupon wire 1) becomes heated. At this stage, the required degree of heating of wire I) may be ascertained by touch and after establishing that the temperature of the wire is sufficient to partially soften, or melt, the wax of sheet 0 so as to permit the incorporation of wire b, the electric circuit is opened by the return of bar 5 to its normal position due to the action of spring 6. After cooling, the wire I) Will remain firmly embedded in the body of the wax sheet c.

The hereinbefore described operation has been explained merely by way of example, and it will be apparent to those skilled in the art that this may be modified without exceeding the scope of the invention. For instance, if desired, the wax sheet might be brought into contact with the heated wire after the electric circuit had been opened.

It may be emphasized that an electric arc may be formed between contacts 4a, tie and 4b, 5b, thus avoiding any possible damage to the ends or terminals d of Wire 29. Further, the bar 5 will easil follow different angular positions of frame a in view of its free movement, thereby warranting a perfect electric connection between terminals d and contact members lia, lib.

Also, in the case of frames of lesser height, these may be placed on the board 8 removing the member 19, thus making possible the contact between the wires and wax sheet.

The resistor 2a may be adjusted, as regards its electric resistance, in accordance with operating conditions in each case, that is, available tension, length and cross-section as well as specific resistance of wire, etc., without exceeding the scope of the invention.

It is to be understood that different modifications may be made of the constructive details of the apparatus, within the scope and reach of the appended claims.

Having thus fully described and ascertained the nature of my invention, and the manner in which the same is to be performed, what I claim is:

1.
