ELECTRIC SEALNG DEVTCE.
Application filed April 2, 1926.
This invention relates to certain novel improvements in electric sealing devices and more particularly to a device ot this character for melting and applying wax to an envelope or like article for sealing the closure laps thereof and has for its principal object the provision ot an improved construction ot this character which will be highly etficient in use and economical in manufacture.
Among the several objects of the invention is the production ot a device ot this character wherein there is provided a simple combination and arrangement oi" parts tor measuring, melting and supplyingpowdered wax to be melted and applied to an article to be sealed.
Other objects will appear hereinafter.
The invention consists in the combination 2U and arrangement oi parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawing `illustrating the preferred .torni ot construction, and in which- Figs. 1 and 2 are vertical sectional detail views of the invention illustrating the preferred form ot construction,
Fig. 3 is a sectional detail view of the same taken substantially on line 3-3 ot' Fig. 2,
Fig. 4 is a fragmentary sectional detail view of the same taken substantially on line 1 4 of Fig. 1, and
same taken substantially on line 5 5 oit Fig. 1. A
i Referring more particularly to the drawing, illustrating the preferred form of construction, a barrel is indicated at and includes cylindrical side walls 1l and a bottom wall 12 having an opening 13 formed centrally therein. The upper end portion ot the barrel is closed by a cap 14 having a central opening 15 formed therein and including depending flanges 16 adapted for trictional engagement with adjacent interior portions ot the cylindrical walls 11.
Arranged in the barrel l0 at the lower end portion thereof, as illustrated in Figs. 1 and 2, is a tubular member 17 defining at its upper end portion a melting chamber 13. The walls oi this melting chamber are spherically shaped to deline an entrance 19 Fig. 5 is a sectional detail view of the Serial No. 99,335.
at its upper end portion. Below this melting chamber 18 the tubular member deiines a receiving chamber 2O opening, at its lower end portion, into a sealing chamber 21 where the melted wax, indicated at 22, isreceivcd for application to an article to be sealed.
The walls of this receiving chamber 2() are likewise spherical in shape and define a restricted passage 23 opening communication between itself and the melting chamber 13. The lower end portion of the tubular member is cylindrically shaped to define the sealing chamber 21 herein mentioned.
This tubular member 17 is preferably formed of heat conducting material so that the melted wax will be retained in melted condition until the same is applied to the article to be sealed, in a manner hereinafter set forth.
Arranged between the interior wall surfaces 24 ot the barrel and the outer wall surfaces 25 of the walls defining the melting chamber is a heating unit generally indicated at A. This heating unit includes an asbestos base 26 receiving a heating coil 27 which is connected in circuit with terminal posts 28 through the medium ot conductor wires 29. This heating coil is dis posed to surround the outer wall portions 25 and in contact therewith so that the heat generating from these heating coils will be conducted by the tubular member to melt the powdered wax received by the melting` chamber and so that wax thus melted will remain in melted condition until applied to the article to be sealed.
Arranged in the barrel 10 above the tubular member 17 is a second tubular member 30. This tubular member is preferably formed of non-heat conducting material and has its lower end portion shaped to define a spherical measuring chamber 31. This portion of the tubular member 30 defines a restricted passage 31 which opens communication between this measuring chamber and the upper end portion 32 of the tubular member 30. This upper end portion 32 oi'l the tubular member 30 deines a funnel shaped mouth 33 including inwardly and downwardly tapered wall portions 34. These tapered wall portions 311 serve to guide the powdered wax 35 into the measuring chamber 31 under certain conditions.
As illustrated in Figs. 2 and 5 a door 36 oli iff
is included as a part of the cylindrical walls 11 for the purpose of permitting replenishing ot the powdered wax to the storage chamber 37 defined by the upper end portion of the barrel 10.
As will be noted in Figs. 1 and 2 the sealing chamber 21 is in registration with the opening 13 to permit the expulsion ot die melted wax applied to an article to be sealed in a manner to be hereinafter set forth.
The mechanism for applying the melted wax to an article to be sealed includes a plungerI 38 mounted for movement longitudinally of the barrel 10. The upper end portion ot this plunger includes a reduced end portion 39 threaded to receive a button e0. rlhis plunger 38 worlrs throughthe centralopening termed in the cap 1st and includes areduced portion el which is adapted7 when the plunger is in the position illustrated in Fig. 2, to open communication between the storage chamber and the measuring chamber 81. 'lhe passage 251 affording' such communicationv is normally'closed by an enlarged portion 42 of the plunger when the plunger is in the position illustrated in Fig. 1. Below this reduced portion al1 is a second reduced portion d?) which is adapted to permit communica yion between the measuring chamber 3l andthe melting chamber 1t when the plunger is in the position illustrated in Fig. 1 with the portion L12 thercot closing passage through the restricted passage 31y This portion 42 ot' the plunger is likewise adapted to close passage through the. restricted passage 19 when the plunger is in the position illustrated in Fig. 2. lVhen the plunger is in the posit-ion illustrated in Fig. 1 the enlarged lower end portion 14 thereof closes passage between the melting chamber 18 and the receiving chamber 20. This enlarged portion A is substantially conical in shape and is ot suoli diameter so as to snugly1 pass into the sealing chamber 21 when the plunger is manually depressed into its lowermost position beyond that illustrated in Fig. 2.
rthis conical shaped end portion le of the plunger has a central threaded bore 45 -lormed therein to receive the threaded stud ab formed as an integral part ot a seal 47.
To momentarily stop depressing ot the plunger 38, tor reasons hereinafter set forth, l provide opposite detents 48 slidably supported by bearing brackets 49 carried by the cap 14 and normally urged .in engaged position with adjacent portions ot the plunger by spring members 50. These de-v tents t8 are adapted to engage in an annular recess 51 termed in the upper end portion ot theplunger, when the plunger is in the position illustrated in Fig. 2. lt
will be noted that when the plunger is in this position communication 1s opened between the melting chamber 18 and the receiving chamber Q() and between tl'ie receiving chamber Q0 and the sealing chamber 21. This permits a certain amount oit the melted wax to iind entrance into the sealing chamber 21 where upon further depressing otl the plunger the seal di' thereot will be brought down upon the melted wax received by this sealing chamber. To permit the required amount ot melted wai; to lind confinement in this sealing chamber the plunger is momentarily resisted from downward movement by the dctents 4S when in engagement in the annular recess 51.
The plunger is normally held in its eX- treme upper position, with the portion 42 closing the restricted passage 31 and with the conical shaped end portion it closing communication through the restricted pas- Y sage 23, by a sprig member This spring member f2 is mounted between the button e() and the cap 1ain embracing position with respect tc adjacent portions et the plunger best illustrated in Fig. 1.
illhen the device is inoperative the plunger is normally disposed to close communication between the restricted passages Q3 and 31. ln this position it will be noted that 'con'inninication is permitted through the restricted passage 19 to permit a predetermined imount ot powdered wax contined in the measuring chamber 3l to find continement in the melting chamber 'i8 where the powdered wax is melted into condition to be applied to the article to be sealed. Upon operation ot the device the plunger is disposed to close communication through the restricted passage 19 and to open communication through the restricted passages 2? and 81. ln this position ot the plunger, a predetermined amount ot the powdereti wax IV is permitted to iind confinement into the measuring chamber 31 and the melted war; in the melting chamber 18 is permitted to pass into the receiving chamber 2O and trom there into the sealing chamber 2l.. Upon iurther depressing ot the plunger' 88 the seal 47 is brought down upon the melted wax confined in the sealing chamber to press the wax therein into adhesive relation with the article to be sealed.
iiiihen the plunger is manipulated to move into its lowermost position to bring the seal fil-.7 down upon the melted wan in the scaling chamber 21 it is manifest that by reason of a inanually imposed torce upon the plunger to move it in the direction to bring the seal into such a position that the action of the springs permitting further movement of the plunger, pass the point ot engagement between the detents and the annular recess. These detents serve in their principal capacity. as herein mentioned, to momentarily stop movement ot the plunger in the direction to bring the seal upon the melted wax. During Ait) this momentary stopping of the plunger the melted wax is permitted to find confinement in the sealing chamber 21.
While l have illust-rated and described the preferred form of construction t'or carrying my invention into eii'ect, this is capable ot variation and modiiication without departing from the spirit of the invention.
