To all whom it may concern:
Be it known that I, DEIANA DOMENICO,
V tion.
The object of the present invention is to provide a device for testing the tightness of barrels and other receptacles, which will permit the barrel or other receptacle to be repaired or rendered tight against leakage while the testing device is still in position ready for use.
In the accompanying drawing, Figure 1 is a sectional View of a portion of a barrel showing my improved testing device in its first position therein; Fig. 2 is a similar view of the same showing the testing device in a second position therein; Fig. 3 1s a sectional View of the testing device detached from the barrel and viewed at right angles to the view shown in Figs. 1 and 2; Fig. 4 is a view of a nut for steam connection.
Referring to the drawing 1 indicates a barrel, of which only the portion having the bung hole 2 is here shown. In said iung hole is inserted a stopper 3 forming part of my improved testing device and comprising av tube 4, threaded as shown at 6 on its outer end, and a slightly conical jacket or bushing 7 of rubber. On to the outer end of said tube 4 is passed a perforated disk 8 abutting against the outer end of the jacket 7. The inner end of said slightly conical jacket abats against a washer 9 of leather and presses said washer against an apertured disk 11 of metal screwed on the threaded inner end of the tube 4.
On the outer end of said tube is screwed a nut 12 and pivoted on opposite faces of said nut by screws 13 are the tines of a. forked end of a lever or handle 14.
From the inner face of the disk 11 extend inwardly rods 16 which pass through holes 18 in a plate 19 said plate being retained in position by nuts 21 secured on the threaded inner ends of said rods 16. Normally closing the hole in the disk 11 is a leather disk 22, into which is secured the threaded outer end of a stem 23, said stem being slidable in a central hole in the pla-te 19, and extending through a central hole in a slide plate 24, the ends of which are recessed, as shown'at 26, to engage said rods 16. A spring 27,
coiled around said stem 23 and compressed between the plates 19 and 24, presses said slide plate against said closing disk 22 and therefore normally maintains closed the hole in the disk 11.
The device is used in the following manner lVhen it is desired to determine whether or not abarrel or other receptatcle is suiciently air-tight, a pipe 28 leading from a source of supply of compressed air, or steam under pressure, is connected with the outer end of tube 4. If compressed air is used it, is sufficient to insert the end of the pipe 2S in the outer end of the tube 4, and the pressure. of the air will be sufficient to make an air-tight connection between the two. If there be used steam of sufticiently high pressure the steam pipe can be connected with the outer end of the tube 4 by any suitable coupling, for which purpose the nut 12 may be formed with a bayonet slot 29.
When the connection has thus been made, the stopper is pressed tightly into the bung hole of the barrel; the rubber tube tightly engages the side of the bung hole. The handle 1s then turned from a position in which it extends approximately in alinement with the tube 4 through a right angle to a position in which it extends at right angles thereto. In so turning the handle, the disk 11 is pressed inwardly with reference to the tube 4, therebv greatly compressing the rubber jacket or bushing 4. The reason for the inward movement of the disk 11 is that the pivotal line of the handle or lever upon the nut is considerably nearer to the end of the lever which engages the disk in the first position than it is to the side edges of the tines of the lever which engage the disk in the second position, since lthis pivotal line is, for the time being, fixed in relation to the tube 4. It. follows that the disk 9 is by the aforesaid movement of the handle moved inwardly relative to the tube 1. Thereby the rubber jacket or bushing is compressed longitudinally and correspondingly enlarged transversely.
The operator now turns a valve 31 admitting compressed air or steam to the pipe 28. The pressure Huid then enters the tube 4 and forces away from the disk 11 the leather disk 22 against the pressure of the spring 27, the guide stem 23 sliding in the plate 19. Thereby the compressed Huid is permitted to enter the barrel. If suicient amount of compressed fluid is allowed to so enter to lill the barrel and if the barrel or other receptaclc is not sul'liciently tight the compressed 'fluid will escape at the leak.
ln order to render barrels air-tight, there is often poured thereinto molten parafiin, which, by rolling the barrel around is caused to lill all the interstices or small holes in the barrel. lt' the barrel is not suti'iciently tight, the paralin, by the pressure of the testing fluid, will be forced through these holes or creviees, thus indicating to the operator the location of the leaks. The operator can then, while the testing device is still in position, calk or otherwise render air-tight said holes or crevices.
The metal disk 1l becomes very hot by contacting with the molten paratiin, and the object ot' the washer 9 is to space said metal disk ll from the rubber jacket or bushing 7, therebjY preventing said jacket or bushing from being injured by the heat from the metal disk 1l.
t will be observed that. the amount of compression of said rubber bushing can be varied by varying the normal distance between the nut l2 and the disk 8, which can be done by screwing the nut around the tube d.
li claim l. ln a barrel testing device the combination of an apertured stopper of suitable form and size to be inserted in the bung hole of a barrel and comprisingr a rubber bushing or jacket and a tube extending axially there through. the outer end of which is arranged to communicate with an end of a pressure fluid tube to conduct pressure Huid into the barrel, guiding means extending inwardly into the barrel and supported by the inner end of the tube, and spring-actuated means, guided by said guiding means, for closing the inner end of the tube.
ln abarrel testing device the combination oi an apertured stopper of suitable form and size to be inserted in the bung hole of a barrel and comprising a rubber bushing or jacket and a tube extending axiresigns ally therethrough, the outer cud ot which is arranged to communicate with an end ot' a pressure tluid tube to conduct pressure fluid into the barrel, guiding means extending inwardly into the barrel and supported by the inner end ot' the tube, and spring-actuated means, guided by said guiding means, for closing the inner end of the tube.
