Specification of Letters Patent.

Application filed. August 4, 1916. Serial No. 113,152.

To all whom it may concern:

Be it known that we, FREDERIC C. Gnown and BENJAMIN I-I. DE HAVEN, citizens of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Cork-Pullers,

of which the following is a specification.

This invention relates to devices for extracting corks from bottles and other similar receptacles, and has more especial reference to an improved device of the character stated, whereby, the stopper will be pulled by suction means.

It is among the aims and objects ofthe V invention, to eliminate the use of the ordi nary form of extractor, which comprises an instrument insertible within the stopper, to which, when embedded within the stopper, a .pull of suflicient force, to cause the dislodgment of said stopper,,is imparted.

This form of extractor is exceedingly obijectionable, due to the manner in which the stopper is mutilated, rendering it unfit for subsequent usage and oftentimes, forcing the same downwardly, into the bottle.

The nature of the invention, more explicitly set forth, may be stated briefly, to comprise a pump provided with suitable pistons and having a cap member arranged upon the lower end thereof, the pump cylinder The improvements in'the details and arrangements of parts will be apparent from an inspection of the accompanying drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a clear understanding of the invention.

In the drawings F'gure 1 is a fragmental side elevation of my improved extractor partly in section as applied to the mouth of a bottle, and

Fig. 2 is afragmental end elevation there- V of showing the arrangement of the operating jaw with relation to the piston rods and cylinder. 7

Referring now more particularly to the drawings, wherein like reference numerals refer to corresponding parts throughout the several views, we provide a pump cylinder indicating the same by the numeral 1, the lower portion of which is contracted as, at 2, and then flared outwardly to constitute the substantially bell-sl1aped cap member 3. A bottom 4 is secured to the side walls of the cylinder 1 by means of a plurality of screws 5 which are passed therethrough at a point adjacent the said contracted portions 2, and have arranged therein, preferably concentrically thereof, an opening 6, which serves to receive the suction controlled valve 7, the lower portion of which has attached thereto, a cross arm 7 whereby excessive upwardmovement of the said valve 7 will be prevented. It will be noted thatv the opening 6 is provided with a reduced portion, thus, forming an annular shoulder 8,, v

consequently providing for. means whereby the beveled portion of the valve 7 maybe effectively seated thereupon. The upper end of the cylinder is open and normally re- .ceives thereover, a screw threaded cap 9,

having an air exhausting opening 10 formed therein, for an obvious purpose. A piston head 11 having an opening 12 therethrough, which opening is normally closed by'means of a flap valve 13, is arranged interiorly of the cylinder and adapted for longitudinal movement therein. To provide for means whereby the piston head 11 may be moved, the rod 141- issecured to the upper face thereof and extends upwardly througha suitable opening arranged concentrically of the screw threaded cap 9 and has formed vupon its upper extremity, an elongated bearing element 15, the purpose of which will be subsequently described. To provide for means whereby the neck of the bottle which we shall designate as a, may be positively engaged with the sides of the cap member 3,

thus affording an air tight connection, we preferably line the same with a resilient material, such as rubber or the like, asat 16, it hemg obvious, that the same will permit the close-engagement of the upper portion of thebottle neck a therewith and consequently, provide for the necessary connection.

In order to provide for means whereby the cylinder 1 may be supported during the operation thereof, we aflix the same to the outer end of the jaw member 17, which member is. provided with handle portion 18,

and has arranged intermediate the ends thereof, an apertured lug 19. A second handle 20 is pivotally connected to the handle 18 by means of a pivot pin 21 which is passed through the apertured lug and through a suitable opening formed in the adjacent end of said handle, the said handle 20 carrying thereupon, adjacent its plvoted portion, an upwardly curved arm 22 the outer end of which is bifurcated to constltute the spaced apart arms 23 and 23, between which arms, journal a roller 24, sup porting the same in position by means of the pivot pin 25 which is passed through the arms 23 and 23. It will be noted upon reference to Fig. 1, that the roller 24. is received within the slotted portion of the elongated bearing element 15 and permitted to travel therealong. Thus, when the upwardly curved arm 22 is forced downwardly by means of the handlev20, the roller 24 will be moved forwardly in the elongated slot of the bearing element 15 until it has reached the opposite end thereof. Upon upward movement of the arm 22, the rod 1 1 and piston head 7 will be drawn upwardly, the roller 24 moving in the elongated slot of said bearing element to its normal position. To provide for means whereby the arm 22 will be normally held in its lowermost position, I secure thereto, a contractile coiled spring 26, engaging the lower portion of said frame with the lower portion 17.'

In using my improved device the flaring cap portion is engaged with the neck of the bottle, thus causing an air tight connection therebetween, by means of the construction as heretofore described. Assuming that the arm 22 is in its lowermost position, the handle 20 is then depressed caus ing the said arm 22 to be moved upwardly, consequently drawing the piston rod 15 and the cylinder head upwardly within the cylinder 1 and consequently, moving the valve 7 from its seat 8, thereby creating a suction within the space below said piston. Should'the stopper be but loosely seated within the mouth. of the bottle neck, this suction as created will be sufficient to withdraw the same therefrom. However, in the event that the same is tightly sealed, the piston head 11 is then forced downwardly again, by means of the handle 20, whereupon, the flap valve 13 will be moved over the opening and allow the air to escape through the exhaust 10 arranged within the closure cap '9, it being noted, that the valve 7 during this movement, has remained upon its seat, thus, closing the opening 5 and maintaining the vacuum within the cap 3. The piston head 11 is then drawn upwardly thus, exerting an additional pull uponthe stopper and causing the same to b dislodged from its seat within the bottle neck. It isof course understood, that the suction may be increased in proportion to the number of strokes required to dislodge the cork from the bottle neck.

By forming the cap 3 substantially bellshaped, it will be obvious that the device may be adapted for use with bottles having various sized heads.

While we have herein disclosed the specific embodiment of the invention, it will be ap parent to persons skilled in the art that the invention is capable of embodiment in other forms and devices differing in detail and arrangement from that shown, as may be in keeping with the hereto appended claims.
