SPECIFICATION forming part of Letters'latent No. 701,791, dated. J une 3, 1902. Application filed January 14,V 1902. Serial No. 89.758. (No model.)

To all whom, it' may concern,.-

Beit known that I, RANDALL B. ANDROS, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Automatic Cork-- screws; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in automatic corkscrews; and the object of the invention is to reduce to a minimum the fric! tion caused by compressing the knob of the handle and forcing a spiral worm into the cork of the bottle.

A further` object to be obtained is to automaticall y force the cork from the spiral worm' by means of a coiled spring after the with drawal of the cork.

With these ends in view the invention consists in the novel construction and combination of parts, as will be hereinafter described, and particularly pointed out in the claim.

In the accompanying drawings, to which reference is had and which fully illustrate my invention,`Figure lis a front elevation of my device, and Fig. 2 is a vertical sectional elevation of the same. p

Referring to the drawings, A designates the compression-knob or handle, Vhaving a recess d formed therein, within which is seated and secured the upper end of a tube F. The upper part of this tube is screw-threaded, as at d', in which engage screw threads formed, upon the periphery of a screw-plug A', said screw plug having a hole made centrally therethrough and a tubular shoulder a3 formed integral therewith to receive revolubly the upper end of a spiral worm B, said parts being located in the upper part of the tube F.

F designates another tube somewhat longer than the tube F and of less diameter which is arranged telescopically in relation to the tube F, the lower end of the tube being provided witha nut or solid portion F2 and having screw-threads cut therein to engage screwthreads formed upon the lower and inner portion of the tube F', this nut having also points c c integral with or secured to the under side of the nut, which engage the cork and prevent the same from revolving, and it is'further provided with a channel or passage-way formed centrally, as at f, through it, corresponding in` configuration to the spiral worm, which. is projected and retracted through said channel in its operation.

B designates the spiral worm, provided at its upper end with a swivel B', which is formed vintegral with said worm and passed revolubly through the hollow shoulder a3 and the screwplug A', to which it is secured and withinwhich it revolves.

D designates a coiled spring located in the tubing and surrounding the spiral worm, the upper end of said spring snugly and securely fitting around the hollow shoulder a3 of the screw-plug A', the opposite and lower end of said spring being secured to the nut or solid portion F,2 Within 4the tube F', upon which the handle C is secured, the securing of the spring to the shoulder of screw-plug A' and to the nut o'r solid portion withinthe tube being for the purpose of preventing the handle and its tube from becoming separated from the spiral worm, the tubing F andF' telescoping and serving as a casing for inclosing the mechanism. The worm is made of sheet-steel of the required width, and the peculiarity of the worm or screw is that the pitch of 'the worm or screw is obtained by a twisting or rolling process. The object of the screw or worm is to reduce friction caused by the compression oi' the knob forcing the worm through the nut or solid portion of the handle into the cork.l The peculiar form of said worin reduces friction over the ordinarily-constructed corkscrew, inasmuch as it permits the piercing ofthe cork instantly.

The surrounding of the worm by the spring khas for its object to forcel the handle to'traverse vertically the swivel worm or screw, which causes the cork to be forced from the spiral worm or screw automatically afterjthe withdrawal of the cork. To extract the cork, the operator simply holds the ,compressionknob and handle together and draws in the ordinary manner.


rounding the worm having its upper end secured to the tubular shoulder of the screwplug, the nut to which the lower end of the coiled spring is secured, a channel formed through said nut corresponding to the form of the worin, and points located on the under side of the nut, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
