Description
Oct. 13, 1931. FRASI-zn, JR
RECEPTACLE cLosuRE Filed July 2v. 192e llllll Patented Oct. 13, 1931 UNITED STATES lPATENT OFFICE JOHN FRASER, JR., F MILWAUKEE, WISCONSIN, .ASSIGrINOIlfk T0 MILWAUKEE 'VALVE COMPANY, OF MILWAUKEE, WISCONSIN, CORPORATION OF WISCONSIN l RECEPTACLE GLOSURE Application filed July 27, 1928.' Serial No. 295,681.
This invention relates particularly to means for hermetically sealing receptacles and especially that type known as thermostatic valves.
Devices of this nature are filled with a suitable fluid, the expansion and contraction of which is utilized to perform various types of work such as closing valves and the like and heretofore it has been difficult to hernietically seal the openings of such receptacles; and this invention therefore has as its primary object to provide a simple and eiiicient means for hermetically sealing a reccpt-acle.
Another object of this invention resides kin the provision of novel means for hermetically sealing a receptacle which incorporates kthe use ef lead shot or pellets.
And a more specific object of this invenresides is the provlision of means for hermetically sealing a receptacle in which an ordinary set screw compresses one or more lead pellets to completely fill the opening to the receptacle.
l/Vith the above and other objects in view which will appear as the description proceeds, any invent-ion resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and 3o more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.
In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the V principles thereof, and in which:
Figure l is an elevational view of a device embodying my invention, with parts broken away and in section, and V Y Figure 2 is a view similar to Figure 1 illustratin g the means for producing the hermetic closure prior to its being compressed.
f Referring now more particularly to the accompanying drawings in which like numerals designate like parts, 5 represents a container which in the present instance is of the type known' in the art as a thermostatic valve having a'valve member 6 formed on its lower portion. The top and bottom walls ofthe .receptacle form diaphragms preferably having a plurality of annular beads 7 to facilitate their movement towards and away from each other by action of the expansion and contraction of a fluid 8 within the receptacle.
The top wall has an apertui'e 9 above which, and in axial alignment therewith an attaching boss or stud 10, is suitably secured. rlhe attaching boss 10 is bored, as at 12, and provided with an internally threaded counter-borel, the bore 12 being of substantially the same diameter as the aperture 9 and forming' a continuation thereof.'l The boss 10 is eXteriorly threaded, ras at 14, to provide means for attaching the device to any desired support whereby the upper wall of the receptacle is stationary and the lower wall carrying the valve member 6 is free to move toward and away fronithe stationary wall according to the thermostatic action of the fluid.
In filling devices of this nature, the fluid is poured into the receptacle in any suitable manner and when full one or more lead shots or pellets 15 are dropped into the counterbore 13, the lowermost pellet resting on the edge 16 at the upper end of the bore 12, see Figure 2. A set screw 17 is then forcibly threaded into the counter-bore 12 to compress the pellets which are sufficiently plastic to 'completely fill the bore 12 and the counterbore 13 beneath the set screw 17. The pressure exerted by the set screw 17 is sufficient to cause the pellets to completely fill the threads of the counter-bore and thereby secures the lead against displacement and as the lead now completely fills the outlet it will be readily apparent that an eiiicient hermetic seal is thus produced at a minimum cost.
I claim:
1. In combination with a receptacle having a threaded opening provided with a shoulder, a soft pellet slightly smaller in diameter than the threaded opening and resting on the shoulder, and screw means threaded into the opening to compress the pellet ,f
rns
against the shoulder and into intimate contact with the threaded opening.
2. The hereindescribed method of hermeti-V cally sealing a-receptacle opening having a shoulder which consists y1n compressing a soft metal pellet against theshoulder and into intimate engagement with the opening walls by means of a screw threaded into the opening. Y V Y 3; A closure for sealing a receptacle opening comprising a pellet of Vdeforrr'iable metal adapted to be compressed to fill the opening', and means formingY part'of the closurefor compressing the pellet.y K
4. The combination with a receptacle having a portion apertured to provide an' inlet for the receptacle, of a soft metallicv pelletadapted to be compressed to completely close the inlet, and means cooperating with said portion for compressing the pellet, whereby the stresses incidental `tothe. compression of the pellet are borne entirely'by said portion.
5.111, combination with a receptacle ,having a portion provided with a threaded aperture'to form an inlet for the receptacle, said aperture being restricted at its inner end, a soft metallic pellet adapted to becompressed against saidfrestricted part of theaperture to completelyy lill the aperture, and screw means threaded in said aperture to compress v the pellet, whereby all vstresses incidental to the compressionof the pellet are borne by said 'receptacle portion withoutv imposing any lstress upon the receptacle proper.
In testimony whereof I have hereunto vaffixed my signature. L K J CHNv FRASER, Jn
