My invention relates to an expanding tool,
the `tool of my invention being of particulary service in connection with sealingdevices for metal containers, though its use is not necessari limited thereto.
- The principal object of my invention 1s to provide an expanding tool which is simple in construction, easily handled, and eiiicacious in use.
Another object of my invention is to provide anexpanding tool which will properly adjust the sealing device in sealing position while the device is being expanded.
More particularly the deviceembodying my invention is peculiarly adapted for use in Vforming a bead 'on a seal which is held on its seat by the tool during the beading operation.
The tool includes a body portion adapted to be screwed into the threaded bushing intended to be sealed. rlhe seal is in the form of a cup which has a seat adapted to be held against another seat by the tool body. At the lower end of the body are expansible segments operated by a handle through a shaft.
Jafter the body is screwed into position the handle is turned relative to the body to move the segments radially and thus torni a bead `on the seal to lock the latter in tight closure condition.
, The above and other objects oit' my invention will become more apparent in connection with the liollowing description taken in con# junction with-the accompanying drawing, in which:
lig. 1 is a crosssection through a bushing and sealing device, with part of the container wall shown in section and the closure plugin- Fig. 2 is a vertical section taken through the expanding tool embodying'my invention;
Fig. 3 is a top plan view of the tool, and Figs. d and 5 are cross sections taken on the line 1 4 of Fig. 2, the segments being shown in normal condition in Fig. 4, and in expanded condition in Fig. 5.
, The form of' work illustrated and in conjunction with which the tool of my invention I may be employed will be first described.
Referring to Figs. 1 and 2, 1 have shown part 'of asheet metal wall 6 eta containersuph this hole, this bushing being shown with an outwardly curled inner edge portion 9 which. grips the inner end pf the aforesaid rim.v
The bushingiis provided with a circums'cribingtlange 10 which is tightly seated upon the container wall. A closure in dotted lines inFig. l) is screwed Within the bushing and is provided with a flange 12 which laps the flange 10. The entire sealing structure comprises two fthin metallic parts,-nainely a seatingmember 14 and a closure cup 15, as shown in my copending application, Serial No. 556,190, tiled August 10, 1931. rlhe -niember 1 4 is of cylindrical shape and has an upper cylinder portion 16 crimped around the curled end 9 of the bushing, an intermediate seat portion 17, and a lower reduced cylindrical portion 18; 'lhe cup is mounted in the opening defined by the cylindrical portion 18 and has a friction lit therewith. rlhe upper edgepf the cup 15 l is rolled to provide'v an annular pocket in lwhich a` gasket 20 of any suitable material is confined. The cup is provided with a circuinscribing bead 21 below the cylindrical portion 18 'to lock the cupA in tight vclosure position and prevent removal of the cup Without detection.' rlhe tool embodying rny invention is adapted to force and form the bead 21. I n
rlllie tool illustrated is inclusive of a central lbody 23 through the center of which extends a vertical shaft 2d.. The upper end of the shaft just above the body is square and receives a square opening ingthe @ruiter of a handle 25 which carries'a hand knob 26. 'lhe handley is held in place on' the .shaft by a washer and nut 27, the latter being screwed on to. a reduced threaded extension 28 ofthe plug 11 (shownhome the cup body to prevent movement of the shaft axially upward with respect to the body.
The lower end of the body 23 has acircular recess providing a circumscribing rim 32 within which are mounted the upper portions of four expanding segments 33. Each of the latter are segmental in cross section and their inner iat surfaces form a square as best shown in Fig. 4. The lower ends of the 'segments form a cylindrical flange 34 divided into sections, preferably four, and the upper outer corner of the ilange is beveled as at 35 to forman expanding edge 36. Each segment 33 is held on the body 23 by its individual screw 37 which is screwed into a threaded opening in the segment and has its opposite end extending into a hole 38 in the rim 32. The segments 33 are provided with two grooves 39 forming circumscribing channels in which are mounted coiled springs 40. The screw 37 may be a plain pin secured at one end either in the h sing or segment.
The body 23 is provided with screw threads 42 and a series of closely spaced. holes 43. A knurled adjustable ring. 44 is screwed onv to the threads of the body and carries a screw 45 having its head portion in threaded engagement with a hole in the ring andl its reduced inner end adapted to projectin the holes 43.
The handle 25 carries a plunger 48 having a knurled linger button 49 screwed on its.
upper end and having an enlarged head 50 at its lower end. A coiled spring 51 surl rounding the plunger and mounted in a recess in the handle is compressed between the upper end of the recess and the head 50. The upper end of the body 23 is provided .with four equally spaced recesses 52 into which the head 50 is adapted to engage.
In applyingl the sealing cup 15 it is dropped within the cylindrical portion 18 of the seal seating member'14. The body 23 is then applied to the bushing 8 and th tool is turned yrthe knob 26 so that the threads on the \b,0dy and the bushing coact to move the lower edge of the rim 32 of the body against the upper; edge of the cup 15 and thus press the gasket 20 against the seat 17. The ring 44 is so adjusted that when the gasket 20 is properly seated the lower edge of the ring engages the to of the bushing and tle tool canbe turne no further. The ring 44 may be ad'usted and locked in adjusted position by t e screw 37 to accommodate varying conditions, such as "variations in' manufacture. As the ring 44 constitutes a stop, proper seating of the cup is assured and there is no danger that excessive pres'- sure will be exerted on the cup with attendant distortion ofthe sealing device.
y After the bodyis screwed into the bush.L
ing as just described, the plunger 48 is pulled upwardly by the button 49, to move the lower end of the plunger out of one of the holes 52 whereupon the handle 25 is given a quarter turn ,relative to the-body 23, the sprin 51 being adapted to cause t e lowerend o rate the segments radially as shown in. ig. ,J5
5, the handle being at the time midway between two holes 52. As the handle moves the remainder of its quarter turn the springs 40 move the segments back to their normal -position shown in Fig. 4. The tool is then removed. l
It' will be seen that when the segments are operated by the cams, their edges eX- pand the lower edge of the cup 15 to form the bead 21 shown in Fig. 1. The bead engages against the lower edge of the cylindrical member 14 of the sealing device to lock the cup in place and maintain the gasket 20 in proper seating condition. rIhe seal is virtually destroyed when it is broken and it cannot be removed with a screw driver or other tool and then be replaced without detection.
Changes may be made without departing from the invention.
I claim: 1. In a tool of the class described for expanding a seal for a threaded bushing, the combination of a threaded body, a handle on said body for screwing said body into said bushing, and expanding` means on said tool and operated by said handle after the body has been screwed into said bushing to -form a'bead on saidfseal.
