ANGELO PICGALUGA, OF LEGHORN, ITALY.
APPARATUS FOR FITTING CAPS TO VESSELS.
Application filed September 24, 1923.
1" 0 all IO/(07H it may concern:
Be it known that I, Ancnro PICUALUGA, a subject of the King of Italy, residing in Leghorn, Etaly, have invented certain new and useful Apparatus for hitting Caps to vessels, of which the following is a specification.
This invention relates to a device for providing vessels with fluid-tight closure caps. The cap according to the invention is preferably made of tin sheet metal, but it may be made of any other convenient metal such as for example brass, aluminium, etc. The cap intended to cover an aperture provided on the lid or top of the vessel to be hermetically closed, a d is pressed against the edge of the said aperture by means of a device or tool for the purpose of producng a closure which is tight to fluids such as petrol, benzine and the like, no packing means bein required between the cap and the {-EClgG of the aperture. If however the vessel contains a very fluid liquid, and if additional precaution is deemed necessary, packing means may be provided such as rubber, leather, paper or other material, as best suited for the liquid in the vessel.
1n the accompanying drawings,
Figure 1 is an elevation of the cap-fixing tool or device in the open position.
Figure 2 is an end elevation of the same.
The left hand side of Figure 3 is a section along the line AB of Figure 1 and the right hand side of the same figure is a m on line til-13 of Figure 1. gures 1, (3. t1 and 10 illustrate the aperture portion of the lid of the vessel to be closed with caps of various patterns placed on their respective apertures and ready to be lined. .in position.
Figures 5, 9 and 11 illustrate the various caps prosed into shape by the tool for the purpose of forming the closure.
Figure '12 shows a cap particularly suitable for vessels to be emptied and re-tilled repeatedly.
Figure 13 shows a cap provided with a cylindrical central neck adapted to be closed by a stopper.
Referring to Figure i, the aperture 1 of the top or lid 2 of the vessel is provided with a rib 3 parallel to its circular edge and lying at a small distance therefrom. This rib is easily pressed out in one operation by means of a suitable machine. The cap t is of suitable size relatively to the aperture to Serial No. 684,379.
be closed. It has an outer flange 5 and a cup-like portion 6 adapted to fit in the aperture 1. The cap and aperture can be produced in a simple way which saves time and reduces the cost of manufacture.
Referring to the construction of Figure (3, the rib 3 projects inwardly. The metal between the edge of the aperture and the rib is suitably curved and inclined, the flange 5 of the cap being correspondingly shaped.
The rib is dispensed with in the construc tion of Figure 8 and a portion of the metal around the aperture is bent inwardly to form an inner wall 8, the cap being shaped as shown in Figure 1. The flange 5 of the said cap rests on the top of the vessel.
In the construction of Figure 10, the metal around the edge of the aperture is bent outwardly as at 9 to form an upwardly extending vertical wall 3. The flange of the cap 5 is bent downwardly to form a recess 10 adapted to receive the upwardly extending portion 9.
Referring to Figure 12, the cap is by way of example that of Figure 4, but it may have any desired shape. A rigid ring 11 of any desired metal such as for instance bronze, iron and the like, and made much thicker than the wall of the top of the vessel, is welded or soldered to the said top. The shape of the ring is in accordance with that of the cap to be fixed thereon. The cap is lined in position as in the other constructions illustrated but the greater thickness of the ring prevents the latter from being put out of shape when the cap is removed so that further caps may be in turn secured and removed.
The construction illustrated in Figure 18 allows the vessel to be used repeatedly. Whatever the shape of the cap, the horizontal wall of the latter is provided with an aperture surrounded by an outwardly projecting neck or extension 12 suitably secured to the cap and adapted to be closed by a stopper which may for example be of the screw-0n type as illustrated.
Figures 1, 2 and 3 illustrate the tool or device intended for securing the cap in position. T 0 this end the shape of the cap is altered according to the tool used. In other words, part of the cup-shaped portion of the cap .is uniformly enlarged to form a circular burr on the vertical wall of the said cap. The cap once press 1 "1 position cannot be removed without being cut. The flange 5 of the cap is simultaneously pressed on to the metal around the edge of the opening to produce uniform contact and to give the closure the appearance of a valve on its seat. This method of securing the cap renders the closure perfectly adherent and fluid-tight. The various caps illustrated are circular, but they may be made polygonal or otherwise with sharp or rounded-off edges.
The cap-securing tool or device is lllustrated in Figures 1 and 2 in the open position, that is to say in the position inwhich it presses the cap in position. The said tool comprises a laterally expanding mandrel made in several sections 13' (four in the drawing) pivoted at 15 in suitable recesses or forks of a frame or body 1 1. The sections 13 of the mandrel have, when closed, a iiuted contour and the dimensions of the mandrel are those of the cap to be pressed. The inner face of each section is provided with an inclined plane, the said planes forming a conical hole 16, engaged by the conical end 22 of a cylindrical wedge member 17 sliding in the frame 14-, for the purpose of expanding and contracting the mandrel. The upper end of the wedge member has wins 20 on which the shanks 18 of the levers 19 are pivoted. The pins 20 also hold the levers in position in their forks formed by two openings in the frame 14 extending upwardly and diverging in order to take up the levers 19 and allow them to pivot. The shanks of the levers 19 are moved upwardly when the handles of the said levers are moved apart, so that the wedge member 17 is raised. The upper conical portion 21 of the latter moves the upper end of the sections 13 outwardly. The said sections oscillate about their pins 15 so that their lower ends are moved towards each other and give the mandrel a diameter somewhat smaller than the internal diameter of the cup-shaped portion of the cap. The mandrel is now introduced into the said portion of the cap which is in position in the aperture to be closed, as shown in Figures 4:, 5, 8 and 10. The handles of the lever 19 are now moved towards each other so that the wedge member 17 moves downwardly. The lower end of the said member is pressed onto the inclined planes of the sections 13 which are thus moved outwardly and forced against the vertical inner wall 6 of the cap for the purpose of imparting to the latter the shape f the outline of the mandrel (Figures 5, 7, 9 and 11). The cap closely adheres to the edge of the aperture and cannot be taken out because of its now enlarged diameter. A perfect closure is thus obtained which is fluid-tight even for liquids such as petrol, benzine, etc.
The number of sections and the diameter of the tool may vary according to the shape and size of the cap to be pressed in position. The number of sections is three for triangular caps, four for square or round cap, five for pentagonal caps, and so forth. Any desired number of sections may however be provided for round caps.
The cap of Figure 13 is pressed in position by a tool by a tool longer in shape in order that the wedge member 17 does not touch the cap when moved downwanlly. The contour of the mandrel may differ in accordance with the type of cap to be fixed in position and with the shape to be imparted to the said cap by the tool.
' What I claim as my invention and desire to secure by Letters Patent is 1. A tool for closing vessels with a flanged and dished cap comprising an expanding mandrel, a wedge member having conical end portions within the expanding mandrel and of such length that it does not contact with the stopper on the cap when moved downwardly, and means for moving the said wedge member relatively to the mandrel.
2. A tool for closing vessels with a stoppered flanged and dished cap comprising an expanding mandrel with pivoted sections, a wedge member having conical end portions within the expanding mandrel and of such length that it does not contact with the stopper on the cap when moved downwardly, and means for moving the said wedge member relatively to the mandrel.
3. A tool for closing vessels with a flanged and dished cap comprising an expanded mandrel with pivoted sections, a wedge member having conical end portions within the expanding mandrel and of such length that it does not contact with the stopper on the cap when moved downwardly, and pivoted levers for moving the said wedge member relatively to the mandrel.
In testimony whereof I have signed my name to this specification.
