Specification of Letters Patent.l

Patented Mar. 18,1913,

Application led April 29, 1911. Serial No. 624,235.

The present lnventlon relates to means `for Y melting and .applying sealing wax to vari ous articles, such as ypackages and the like that 'are to be sealed, a-nd the primary object Y is toprovide a practical structure, by means of which the wax, will be expeditiously melted and can be properly applied to thel surface or article to be sea-led, the'wax being out ot therange vof action of the heater when not 1n use, so thatfdripping and .waste is avoided. y

An embodiment of the invention that has proven entirely practicable is disclosed in the accompanying drawings, and is de-y scribed 'in the following specification, but itwill be., evident from an inspection of the claims hereto appended that the'saidv invention is not restricted to the particular struc turev set forth.

Ine the drawings: lFigure 1 is a view in elevation of the instrument. Fig. 2 is a longitudinal sectional view tlrierethrough, on

' (i is a Vdetail perspective view. illustrating the structure of one of the heater elements or sections.- Fig. T is a detail view ot' a modified form ,of construction. 'l`i'g- S is a. sectional view on the line S8 of Fig. 7. Similar reference numerals designate corresponding" 'parts in allthe figures of the drawings. y

ln the embodiment illustrated, an electric heater is employed, composed of sections or elements 9 that are oppositely disposed. are spaced apart, and have their opposing faces convergently arranged. The heating members preferably consist of blocks of insulating material. 10. on which is lwrapped resistance wire 11. the whole being suitably in-g,

cased in insulating sheets l", as will be evident; These heater sections or members are mounted 1n casings 12 that are carried by 55 hollow arms 13 filled with insulating mate- 'Fhe arms are ltemperature of the room in connected by a transverscl)v disposed yoke or bridge piece '16. `ln the preferred torni ot` construction, one of the leads l located in one of the arms is the negatii e, hile that in the other arm is the positive. each of course being electricallyy connected to the heater ser tion. and each ot these coils ll being in turn connected to the adjacent casing l2 so that the circuit is completed thrt'iugh the casing fand the bridge piece or yoke 1G'. The rear ends'of the leads l5 are connected to contact .elements 17 that project longitudinallyfrom -the vrear ends of said arms.

Slidably mounted on the arms 13 and between the same is a wax holding device, in the form of anangular open-ended tube 18 that extends beyond' the rear end's of said arms. and has the portion between the arms preferably in the form of a hollowvhcat-insn lating boxing 1t). This tube or holder lo arranged to receive a stick ot sealing wax, as 20. 'and it will be evident that the inner pointed end of said wax can be moved into and out oi coaction with the heater elements when the'holder is movedtoward and away from the same. The side-walls of the bote ing 19 are formed with lengthwise-extending ribs 19* each pair ot which embraces one ot' the' arms 13. Hence, the tube 18 is guided on the arms 13 b v these ribs'19x. The tube is moved by placing the 'casings 1Q on the envelop to be sealed. (the instrument being held vertically)`- and then pressing down upon the casing 37 to which the tube is attached at its ends and which surrounds the tube (Fig. 4). Mounted upon the rear portion of said holder are suitablev binding posts El carried on insulating blocks Q2, and connected to Contact plates QS'that arevmovable into and'out ot engagement with the contact tongues 1.7. Leads 24 from any suit-able source of current are connected to vthe binding posts 21. With this arrangement, it will be evident. that when the wax holder is moved to present 4the wax to the heater, the circuit through said heater will be closed by the Contact plates 23 coming into engageinentwith the tongues 17. In order that the heater may be maintained above the normal which the instrument is placed, and yet below the melting point of the wax, if desired, shunts of resistance material connect the plates 23 and the tongues 17, so as to always maintain a weak current through the heater. This structure is-illustrated in Fig. 2, wherein it kthe tube.

willbe noted that the resistance wires 25 are connected to plates 26 mounted on insulating blocks 27 that are in turn carried by the tube. These plates 26 are always -in engagement with the tongues 17 lnorderto move and n rmally maintain the wax out of coaction With the heater, springs. 28 are employed that are connected at. their front ends to arms 18X which project from' the front end of the holder 18 through slots 1.9* -formed in the boxing4 19 aiid,at their rear ends to the rear portions of the arms 13, these springs being extended when the holder is moved toward the heater.

For the purpose of locking the holder with the wax in coaction with the heater and to prevent the springs 28 acting, a latch is.

employed that is inthe tormot' a spring` 29 secured at one end, as shown at 30 to tlie'box.

ing 19 and having an actuating stem 3l. fixed upon it, which projects through a key-hole slot 32 in the volte 16. This actuating stem or knob has an enlarged lower portion t3 that springs up into tlie enlarged `portion 3l of the key-hole slot 32 when the `wax holder is advanced, thus locking said holder against retrograde movement under the action of the spring 28. The latch 29 has an inwardly turned end 35 that passes through a lengthwise-extending slot 35X t'ormcd in the boxing 19 and then through a transverse slot SG in the holder so as to engage with' the lstick of wax 20, as will be clear by reference to Figs. 2 and lith this arrangement,

it will be evident that when the wax holder is in its reariiiost position, the latch 2S) will of necessity bedepressed, inasmuch as the enlargement' ot the stem is confined beneath the yoke 1G. The inwardly turned terminal 33 is therefore clamping the wax stick and holding itiagainst movement in 'lien, however, the wax holding tube is Iiioved forwardly to present the wax to the heater` tlic springs 28 will be elongated, and :is soon as the enlargement comes to a position in trout of the enlarged po`rtioii vt-l of tlic key-hole slot, 32. the latch will move outwardly, therebvv releasing the waxand permitting it to feed by gravit); freely to the heater as rapidl)Y as it. is melted. To carry said wax out of the yrange ot' said heater, it is only necessary to press the stem 3l inwardly. The lirst iiiovenient will therefore be to again clamp the wax to the Wax holding device, and as soon as the enlargement 83 is out of the key-hole slot. g

the springs will react to move the holder with the wax rearwardly. In the preferred embodiment of the invention, the mechanism, with the exception of the outer endof the stem and the heating elements inclosed in an outer casing 37.

the end ot' cach operation.

'vice be not' melted. The arms 13 which act as heath-carriers are, as is clearly shown in the drawings, spaced apart and separated by an opening which permits the free circlilatioii of the vouter air-around the piece of wax whicli'e'xtends from the outlet end of the wax-holder 18.. In this way this portion of the wax is kept air-cooled: Again, when the wax-holding device 18 is in operative or active position, in which it presents the wax to the heaters 12, its outlet end is beyond the lmelting range of the heaters 12; that is, the outlet end is, as is shown in the drawings, so far removed from the heaters l2 that the wax at the outlet endof the wax holder 18 is not melted l `urtherinore, by means ot the air-gaps between t'he boxlike easing 19 and thc wax-holder 18 (Fig. 4) the latter is heat-insulated. To prevent a bacleftlowY of the molten wax, the heating elements .l2 are spaced apart and separated by an opening which permits not only a free endwii-e llow of molten wax but a flow laterally (it will be understood that the instrument will be held with the stick of' wax extending vertically). lere the molten wax to flow back into thev outlet end of the waxholder 1S upon laying the latter down on a table, for example, the melted wax would upon cooling seal the stick of wax in the holder 18. Where the. end to Ibe melted is inclosed in a tube, it is obvious that the inolteii wax will upon cooling solidify and seal the outlet ol the tube and the solidified mass of wax must be remclted before any tlowy can take place. lvlheii a gate or valvefis provided tor controlling` the liow from such a tube, this gate will be sealed againstanovement by the cooling ot the molten wax at waste of electrii,l energy (or heat) must result in such :in instrument irom the necessity of again melting the wax in the outlet end o'l' the tube no matter how little sealing wax is re'- quired ior the next operation. Furtherniorc. experiment hasl demonstrated that such a tube will almost certainly overheat the wax, which then gives olll `smoke, thc production ot which it is, of coursefw'cry desirable to prevent.

Willi the instrument liereinbet'orc described. it will bc clear that wax can be uuieklv heated to the melting point and yet cannot be overlu'ated, because of the spaced heaters employed. Furthermore because ot' 1 the open .-iructure. the wax as soon as it i,`
