A nman filed June 18,1903. Serial No. 162,092.

To all whom it may concern: I Be it known that I, CHARLES HENRY BURC K- ETT, a' citizen of the United States, and a resident of Glenridge, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Closing Receptacles, of which the following is a specification.

' This invention relates to means for closing receptacles; and its object is the production of a machine by means of which receptacles, cans, bottles, and the like can be closed and sealed with their charges of material and the receptacles; -having a vacuum therein or having a gas OI'iVfi-POI' in addition to their charges of material.

Referring to the drawings, Figure 1 shows an elevation and partial axial section of my invention. Fig. 2 is a plan view of Fig. 1. Fig. 3 represents an enlarged axial section of a portion of Fig. 1. Fig. 4 is a plan view of Fig. 3 and section on the line 90 w thereof. Fig. 5 shows the plan view of'a wing-nut. Fig. 6 is .a side view of a link.' Fig. 7 represents a plan view of a supporting-bracket. Fig. 8 represents a plan view of a platform. Fig. 9 shows a partial section of Fig. 1 on the line as. Fig. 10 represents a partial axial sec.- tion of a modification of my invention. Fig. 11 represents a plan view of Fig. 10 with a The machine is shown to comprise a foundation-frame A, containing a threaded boss 0, for a screw B, having a hand-wheel B and a platform C for supporting a receptacle D. The platform C has wings C in which are formed bearings C that fit on the columns and guides E, and a half-collar C extends from the upper face ofthe latform to hold the receptaclesD centrally t ereon. Threaded bosses a extend from the frame A and support columns E, on the upper end of which is secured a supporting-bracket E,

On a barrel I, fitting loosely in the su portingbracket E, there is journaled the orked lever F, having the counterweight F, that is fulcrumed on a pin G, supported in a lug e, extending from the bracket E. A lever H, with an'arm H, is fulcrumed on a pin it, secured in lugs e projecting from the bracket E A link F is pinned to the end of the lever H and connects with the lever F by means of the pin f. The supporting-bracket E contains a central opening for the barrel I and has the ribs 6 running to the hubs e, that secure the ends of the columns E. The barrel I is internally threaded at its upper end for the stem K, which carries the nut K and cross-bar K diameter below its threaded. portion, as shown at K after which it swells out to form jaws K, that grip the wings m of a Wing-nut M, which is carried on the bolt L, extending from the cross-bar N, secured in the upper endof a receptacle D. The said nut M jams the packing d against the cover D. of the receptacle, the cover fitting over the edges of the receptacle, as shown at cl. The barrel I terminates in cap'P, recessed for a disk of pliable material 1 and its chamber I is con- The said stem is decreased in nected with the piping'J, which leads to a three-way co ck J, having the piping which may be connected to a vacuum-receiver, and v the piping J which leads either to the atmosphere or a reservoir of a special gas or vapor.

To operate my invention, the receptacle D is charged with the material it is to hold, the

cross-bar N and cover D are placed in posi, tion, and the wing-nut M partially screwed on thebolt L to leave an opening between the face of the packing d and the beveled face of the wing-nut'M. The platform C is next raised to the roper position by means of the hand-wheel so as to allow the receptacle D, with the cover D, to about fill the space between platform C and the said pliable disk 1. The receptacle is then placed upon the platform C, being held in position by thehalfcollar C thereon.

Various tables C with different diameter of half-collars C are provided for the apparatus so that each size of receptacles when laced against the half-collar C will center dlrectly under the center of the barrel I. The lever H is then pulled down, which forces the ca I down, which in turn forces the pliab e packing I against the outer to rim of the cover D, and thereby forces t e cover D down into position on the receptacle D, jamming the pliable disk I between the cap I and the cover D and making an air-tight joint between the cover D of the receptacle-D and the said disk at the outer top edge of the said receptacle. The operation also makes an airtight joint between the receptacle and its cover and grips the said receptacle and cover between the latform C and the cap I. The jaws K of t e stem K are made to straddle the wings m of the nut M, and the three way co'ck J is then opened to make a connection through the piping J 2 between a vacuum-receiver and the chamber I, by which the air is exhausted from the said chamber I and the receptacle D, thereby formin a vacuum therein. The hand-wheel K is t en turned to screw down the nut M, thereby jamming it against the packing d and closing the central opening in the cover of the receptacle. The cock J is next turned to close the connection with the vacuum-receiver and is opened to the atmosphere through the iping J to admit air to the chamber I an to secure atmospheric pressure on the top of the receptacle before the mechanical pressure exerted by the cap I is released, after which the receptacle is removed.

A modification of my apparatus is made by connecting the piping J of the three-way cock J, which ordinaril admits air to chamber I, to a receiver ho ding a gas or vapor. With this modification the apparatus works exactly as before described up to the point where a vacuum is formed in the receptacle. Then instead of the nut M being screwed in place at once the iping J of the cock J, which connects Wit a receiver holding a gas or vapor, is opened, and the gas or vapor allowe to pass through the chamber I and into the receptacle through the opening around the bolt L to take the place of the vacuum in the said receptacle. The handwheel K is then turned to screw down the nut M, thus sealing the receptacle with the gas or vapor therein, after which the lever H is raised and the receptacle removed.

Another modificatlon of my invention consists in substituting for the platform C the platform C, having lugs C to maintain them on the uides E and side walls C, and instead o the cap I I use a ca I, which has extending therefrom the wal s I. A packing-ring P is held in place by a ring P and bolts P". Lugs I. extend from the cap I to maintain it on the guides E The walls C are of a diameter to fit on the inside of the walls I, the packing P making tight joints between them. To operate this last modified form, the screw B is lowered, areceptacle D with cover D loosely thereon, is placed on the platform C", and then the said platform is raised, by means of the screw B until an air-tight joint is made between the sides C of the said platform and the packing-ring P of the sides I of the cap. 1*. Then the air is exhausted from within the spaceinclosed by the platform and cap, as well as from the receptacle. Next the lever H is pulled down, which jams the pliable disk I against the cover D of the receptacle, fore-- ing the said coverinto proper position upon a stem' with jaws in the hol ow barrel, means to turn the said stem, piping with a cock con nected with the hollow barrel.
