To all whom t may concern:

Be it known that I, EDWARD D. SCHMITT, a citizen of the United States, residing at 2444 Woodbrook avenue, in the city of Baltimore, and State of Maryland, have invented certain new and useful Improvements in Machines for Applying Bottle-Seals; and I do declare the following to bea full, clear, and exact description of theinvention,such as will enable others skilled in theartto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this speciication.

This invention relates to machines for applying bottle-seals, and more especially for applying a seal of special construction illustrated in the accompanying drawings, as well as seals that would require the same, or substantially the same, mechanical operation to seat them and lock them in place.

The object of the invention is to so construct the sealing-head as a whole that the operating parts therein will eectively seat the seal and lock the same in place'in the inside of the bottle-neck in such a manner that the danger or risk of chipping or otherwise injuring the bottle or seal will be impossible.

Afurther object is to provide a simple and durable machine of this character in which the parts are not likely to get out of order.

Other objects and advantages resulting from the construction shown and described will later become apparent.

In the drawings, Figure 1 is a side elevation of the machine; Fig. 2, afront elevation thereof; Fig. 3, a central vertical section of the sealing-head, the parts thereof being in the position they occupy before the sealing operation. Fig. 4 is a sectional view of the head with the parts thereof in nal operative position, showing a seal seated in the bottleneck. Thisviewis taken transversely of the line upon which Fig. 3 is taken to more clearly show the construction of the seal and the positions of the operative parts of the plunger relative to said seal. Fig. 5 is a bottom plan View of the lower slidable portion of the head adapted to be engaged by the bottle-head in ,center of said table.

the sealing operation. Fig. 6 is a sectional View of this slidable portion, showing the grooves for guiding and holding the seal in putting the same in place before the sealing operation; and Fig. 7 is a perspective view of a seal which may be applied by this machine. Fig. 8 is a perspective view of the centering device for holding and centering the bottle upon the bottle-supporting table.

Referring to the drawings, the numeral 1 represents the frame, preferably formed of cast-iron with a widened base 2, through which pass bolts or screws to fasten the machine iirmly in place upon the floor or other support. This frame is formed with a forward extension 3, having laterally-extending plates 4, to which, by means of bolts or otherwise, I fasten the plate 5 integral with aA split sleeve 6, in which is adj ustably held a short shaft 7, carrying the bottle-supporting Y numeral` 13 indicates the bottle-centering de.

vice provided with a lower horizontal arm 14, having an elongated slot 15 therein for the passage of a set-screw 16, which secures the device to the underside of the table,as shown, and permits of adjustment to and from the The upper part of this device is formed with two diverging arms 17, which embrace the bottle and hold it in proper position upon the table. y

Rigidly secured by bolts or otherwise to the slightly-overhanging portion 18 of the frame is a sleeve 19, forming a part of the sealinghead 20, which will now be described. This sleeve is provided with a vertical slot 21, through which extends rearwardly an arm 22, preferably integral with a vertically-movable plunger-carrying core 23. The arm 22 is adjustably secured to the upper end ot' a vertical rod 23', pivoted at its lower end at 23 to the foot-lever 24, which is in turn pivoted in the cut-away portion 25 of the frame at 26.

As is usual in machines of this character the foot-lever is held normally raised by aspring 26', which in the present instance also keeps the plunger-carrying core 23 normally raised in the sleeve. Y

In carrying out my invention I bore the K core vcylindrically,as indicated-by the numeral 27, for the reception of the compound plunger 2S, preferably, -Ihough not necessarily, formed in three pieces, one piece constituting the upper member 28, which, as will presently appeal', serves to lock the seal in the or bore 34. The upper member is provided with a head and a stem 36,v operating between the parts 33 of the lower member, and this stem terminates considerably above the ends of the lower plunger member for a purpose that will become apparent. Interposed between the vunder side of a screw-plug 37 and the head 35 of the upper plunger member is a strong spiral spring 38, and between the under side of said head and the heads 30 of the lower member is a spring 39, preferably not so strong as the spring 38.y Between the under side of the shoulder 31 and a slidableI lower portion 40 is a spring 41, preferably muchvwealier than either of the springs just mentioned. y y

',.The lower end of the core is externally screwthreaded, as indicated by the numeral 41', to adaptit to receive the internally-screw-threaded ring 41". This ring serves to hold the slidable portion 40 in place in the core. The slidable lower portion 40 is provided with a central opening for the passage of the legs of the lower plunger member and the reception of the stem of the upper member in the sealing operation, as shownin Figs. and 6. This slidable Vportion is further provided with two oppositely-disposed inclined grooves 42 for the reception of the arms of the seal and to guide it into its -proper place in the head.

To add to the neatness of r the construction,

` I preferably cover the head with a metallic Ass cap 42, which can be readily removed when it is desired to reach the screw-plug to adjust the tension of the upper springs or to remove the operating parts of the plunger.

Having described the mechanism of the machine, I will now describe its operation.

A lled bottle is placed upon the table concentric with the sealing-head and a seal, such as is illustrated in the drawings, is placed in the head. The foot-lever is vnow depressed, which will, through the medium of the rod 23', cause the plunger-carrying core to descend until the bottle-head comes in contact with the slidable lower portion 40 in the core, and this portion will be moved upwardly against the tension of spring 41, thus guiding the legs of the lower plunger member into the bottle-neck. Afurtherdownwardmovement of the core will seat the seal under the yielding pressure of spring 39, and a still further downward movement of the core will bring the upward extensions 32 in contact with the under side of the'head ofthe upper plunger member, when both plunger members will move upwardly together' for avery short distance against the yielding pressure of the strong spring in the upper part of the core. This movement will bring the lower end of the stem 36 into engagement with the locking means of the seal and cause the same to enter the depression a in one arm of the seal. Upon releasing the foot-lever all of the parts wi1l`be returned to normal position vby the spring operating on the foot-lever to return the plunger-carrying core and the springs in the core to return the plunger parts.

I claimn l. A machine for applying bottle seals, comprising an outside sleeve, a verticallymovable core in said sleeve and containing a compound plunger, the parts thereof being spring-pressed and each member capable of a movementindependent of the other in the core, one of said plunger members being adapted to seat the seal in the inside of the bottle-neck, and the other adapted to engage the locking means of the seal to lock said seal in place therein, substantially as described.

2. A machine vfor applying bottle seals, comprising an outside stationary sleeve, a verticallymovable core in said sleeve containing a compound plunger, the parts thereof being spring-pressed and each member capable of a movement independent of the other in the core, one of the plunger members being adapted to seat the seal in the inside of the bottle-neck, and the other to engage the locking means of the seal to lock said seal in place in the bottle-neck upon the downward movement of the core, and means for so moving the core, and means for restoring the core to normal position after each operation, substantially as described.

3. Ascal-applying machine, comprising an outside stationary sleeve, a vertically-movable core in said sleeve and containing a com-` pound plunger, the parts thereof being springpressed and each member capable of a movement independent of-eaeh other in the core, one member being adapted to seat the seal in the inside of the bottle-neck, and the other to engage the locking means of the seal to lock said seal in place therein upon the downward movement of the core, a vertically-movable spring-pressed lower portion, slidable in said core and adapted to be engaged by the bottle-head in the downward movement of said core to guide the ends of the plunger members into proper position to operate upon the seal, substantially as described.
