HARRY BITNER, OF BERWYN, ILLINOIS, ASSIGNOR TO ARCADE MANUFAC- TURING COMPANY, OF FREEPORT, ILLINOIS, A CORPORATION OF ILLINOIS.

CORK-FULLER.

Specification of Letters Patent.

Patented Feb. 26, 1907.

To tZZ whom, t may concern:

Be it known that I, HARRY BITNER, a citizen of the United States of America, residing at Berwyn, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cork-Fullers, of which the following is a specification.

My invention relates to certain new and useful improvements in cork-pullers and its object is to produce a device of this class which shall have certain advantages, which will appear more fully and at large in the course of this specication.

To this end my invention consists in certain novel features, which are shown in the accompanying drawings as embodied in my preferred form of construction.

In the aforesaid drawings, Figure l is an elevation of a cork-extractor embodying my invention, one of the casing-sections being removed and certain portions being shown in central longitudinal section to illustrate the construction. lfig. 2 is a transverse section in the line 2 2 of I1 ig. 1. Fig. 3 is a perspective view of the. corkscrew-carrier. Big. 4 is a perspective view of the bearing-clip. Fig. 5 is a central longitudinal section through the bearing-clip, showing the manner in which it is secured to the worm.

Referring to the drawings, A is a suitable case in which is non-rotate bly and reciprocably guided a corkscrew-carrier B, adapted to be reciprocated by a crank C, moved by an operating-lever or handle I) and connected with the corkscrew-carrier by a link or pitman c.

E is a suitable nut threaded to embrace a worm F, swiveled in the corkscrew-carrier, the said nut being reciprocable in the guideway of the case below the corkscrew-carrier. A block G is pivoted to the nut E and is shiftable by means of a lever II, actuated by a cam I on the operating-shaft, the said block being adapted when moved to lock the nut alternately to the corkscrew-carrier and case during the pulling and stripping movements of the device.

All the parts heretofore set forth are old and well known and are fully illustrated in approximately the same relations as herein shown in many prior patents, among them the patent to Charles Morgan, No. 620,949.

My present invention relates particularly to the means for rotatably securing the worm F in the corkscrew-carrier B, and it will be obvious that this feature will operate as successfully and perform its functions in the same way in any device of this class where the nut serves the purpose of rotating the worm and where the carrier is moved longitudinally relatively with respect to the nut to effect the operation. This will include, obviously, eXtractors of the long-stroke typesuch, for example, as that illustrated in the patent to Ennis, No. 642,691-extractors of the double-stroke type-such, for example, as are illustrated in the patent to Tscherning, No. 728,517-and many others devices.

The particular swiveling mechanism forming the basis of my present invention will now be described. The corkscrew-carrier B is provided with a chamber b, preferably eX- tending from front to back thereof, and the lower wall of said chamber is slotted or notched from one side, preferably from the front at b. J indicates a spring bearingclip, preferably of .hardened spring-steel. This c ip, it will be seen, is U-shaped in form, one of the legs thereof having a perforation y', through which the worm I" can be passed, and the other leg having an upwardlystamped conical bearing-socket j, adapted to receive a conical point f, provided on an enlarged head j" on the upper end of the worm. The worm is placed in position in the bearing-clip as illustrated in Fig. 5-f. e., it is screwed through the perforation until its head bears against the perforated leg of the bearing-clip-when the pointed end of the head is snapped into place in the conical socket. Thereupon the bearing-clip and the head of the worm can be inserted in the corkscrew-carrier, the worm passing through the slot b and the upwardly-projecting bearingsocket j passing through a groove b2, provided for the 'purpose in the upper side of the chamber t of thecorkscrew-carrier B. Inward movement of the clip and worm is limited by engagement of the clip with a shoulder b3 in the upper face of the chamber l), and when the carrier is placed in the guideway of the case outward movement is prevented by engagement of the clip with the vertical xvalls of the guideway, as illustrated in It will be observed that by the means set forth herein the worm is furnished with a hardened-steel bearing and is also arranged IOO so that practically no side thrust against the practically soft material of the corkscrewcarrier can take place. In practice the worms will be furnished to the trade with the clip in place upon them, so that when a worm breaks and a new one is inserted a fresh unworn bearing will be used. It will also be obvious that the worm can be very readily removed and replaced without the use of any special tools or the assembling of any parts which are not furnished in their assembled parts by the manufacturer.

I claim as new and desire to secure by Letters Patentl. In a device of the class described, the combination with a longitudinal guide, a corkscrew-carrier, a worm, and a nut threaded to embrace the worm, of a removable bearing for the upper extremity of the worm, adapted to occupy a suitable chamber in the corkscrew-carrier and to be removed from said chamber while secured to the worm.

2. In a device of the class described, the combination with a suitable guide, a relatively movable nut and corkscrew-carrier and a worm threaded in the nut, of a bearing for the upper extremity of the worm, secured to said worm and adapted to be placed in and removed from a chamber provided in the corkscrew-carrier, while secured to the worm.

3. In a device of the class described, the combination with a suitable guide, a relatively movable nut and corkscrew-carrier and a worm threaded in the nut, of a bearing-clip secured to the head of the worm and adapted to be inserted in and removed from a suitable chamber in the corkscrew-carrier.

4. In a device of the class described, the combination with a suitable guide, a relatively movable nut and corkscrew-carrier and a worm threaded in the nut, of a U- shaped bearing-clip having a perforation in one leg through which the worm can be threaded to bring the head thereof within the clip, said clip being adapted to be inserted in place in a suitable chamber in the corkscrewcarrier.

5. In a device of the class described, the combination with a suitable guide, a relatively movable nut and corkscrew-carrier and a worm threaded in the nut, of a U- shaped bearing-clip having a perforation in one leg through which the worm can be threaded to bring the head thereof within the clip, said clip being adapted to be inserted in place in a suitable chamber in the corkscrew-carrier, the worm passing through a notch in the bottom of the chamber.

6. In a device of the class described, the combination with a suitable guide, a relatively movable nut and corkscrew-carrier and a worm threaded in the nut, of a U- shaped bearing-clip arranged to embrace the head of the worm, the upper leg thereof having a socket for the head, said clip being adapted to be inserted in a suitable chamber in the corkscrew-carrier.
