ELECTRIC SEALER Filed March 11, 1951 MHHHH vwemtoz flndrew (7r0j1 Patented May 3, 1932 UNITED STATES PATENT ()FFICE ELECTRIC SEALER Application filed March 11, 1931. Serial No. 521,766.

This invention relates to improvements in sealing apparatus, particularly to an electric sealer, and it is the principal object of my invention to provide a sealer avoiding the use of matches and candles thus avoiding the burning of hands and fingers, and to avoid burning or otherwise discoloring the sealing wax so as to produce clean and clear seals of any even the most delicate shades.

Another object of my invention is the provision of an electric sealer allowing the use of the sealing wax to its smallest part.

A further object of my invention is the provision of an electric sealer automatically feeding the wax to the melting point and allowing a quick and ready removal from this point if not further to be used.

A still further object of my invention is the provision of an electric sealer of simple and inexpensive construction, yet durable and highly efiicient in its operation.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds and will then be specifically defined in the appended claims.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a longitudinal sectional side elevation of an electric sealer constructed according to my invention, in position for operation.

Fig. 2 is a view similar to Figure 1, with the sealer in its position of rest.

Fig. 3 is a front elevation of the sealer.

Fig. 4- is a cross section on line 4-4 of Figure 2.

Fig. 5 is a'perspective view of the holder for the sealing wax on an enlarged scale.

As illustrated, the sealer comprises an elongated hollow body or housing 10 into which engages endwise aplunger 11, having an outer handle 12.

A seat 13 for the sealing wax 14.- is substantially composed of a base 15 from which extend a plurality of fingers 16 substantially L-shaped in cross section and adapted to engage the sealing wax and hold the same as shown in Figure 5.

The lower face of the base 15 has secured thereto a holder 16 to which is attached one end of a spiral spring 17, the other end of which is secured to the inner end of plunger 11. A leaf spring 18 is secured at its lower end to the inner wall of housing 10 and engages a shoulder 19 in a chamber 20 in plunger 11.

A small plunger 21 having an outer operating knob 22 is adapted to be moved with its shaft in an elongated slot 23 in the housing 10 and brings spring 18 into and out of engagement with the shoulder of the plunger to advance or retract the same, and hold it in adjusted position.

Near its upper end the housing has attached thereto the bracket arms 24, 25, carrying a head 26 containing a resistance 26 and adapted to be engaged by a knife plug 27 connected by means of cables 28 to a source of electricity.

In operation, the normally extended plunger is pushed into the housing as shown in Figure l and compresses the spring 17 to bring the sealing wax bar 14 against the resistance 26. If now the knife plug 27 is connected with the head 26, the resistance wire will begin to glow and melt the wax and the same may be used to drop onto the places to be secured by a seal.

By the proper operation of the push pin 21 the sealing wax may be properly advanced against the resistance in proportion to its use.

It will be understood that I have disclosed the preferred form of my device only as one example of the many possible ways to construct my device and that I may make such changes therein as come within the scope of the appended claims without departure from my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. An electric sealer comprising a housing, a plunger endwise engaged therein, a sealing wax seat, a spring between said seat and said plunger, a means for electrically melting the wax, and means for gradually feeding the wax in proportion to its use to said melting means.

2. In an electric sealer a housing, arms on said housing, extending beyond the same, a head held by said arms, separated from said housing, a resistance in said head, and a knife plug for connecting said head and resistance to a source of electricity, means for seating the sealing Wax bar, and .a means for gradually feeding the same against said resistance.

3. An electric sealer comprising a housing, a plunger endwise engaged into said housing, a handle for operating said plunger, a seat for the sealing Wax, a coil spring attached at one end to the plunger and at the other end to said seat, a means for electrically melting said wax, and means to connect said melting means to a source of electricity.

4. In an electric sealer, ase'at for the sealingwax comprising va :base, aplurality of substantial'ly 'L-sh'aped fingers extending from said base to engage the edges of the sealing Wax bar and hold the same on its seat, means for electrically melting the Wax, and means for gradually melting the 'feeding Wax tosaid melting means.

In witness whereof I havesigned my name to thisspecification.

ANDREI/V GROH.
