CORK-FULLER.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed May 9, 1904. Serial No. 206,985.

T 0 all whom it may concern:

Be it known that I, RAYMOND B. GIL- CHRIST, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Cork-Pullers, of which the following is a full, clear, and exact description.

The invention relates to cork-pullers and aims to provide, an improved'simple construction which is etficient in operation and which can be produced at a low cost.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:v Figure 1 is a view in side elevation of a cork-puller embodying one form of the invention, parts of the frame or casing being shown in section to disclose the operating mechanism, which is shown in normal position. Fig. 2 is a similar view, the operating mechanism being shown in a position assumed when the corkscrew has penetrated a cork and the latter is being drawn. Fig. 3 is a vertical section on line 33 of Fig. 1. Fig. 4 is a section taken on line 44 of Fig. 2. Fig. 5 is a section on line 5-5 of Fig. 2. Fig. 6 is a section on line 66 of Fig. 1. Fig. 7 is a detail sectional view of the cork-screw and the carrier. Fig. 8 is a perspective of the nut-lock. Fig. 9 is a perspective of the nut. Fig. 10 is a detail view showing the preferred form of nut-lock.

The operating mechanism is sustained by a frame or casing of suitable construction, usually formed of sections 10 and 11, fitted together so the operating parts will be sustained thereby in proper relation. The

frame may be provided with a clamp 12 'whereby the cork puller can be secured to a fixed support, such as a table or counter.

An operating lever 13, is provided with an integrally formed shaft 14 journaled in bearings formed in the frame-sides and a crank 16 and has its free end provided with a handle 15. Said shaft and leverare confined against end-play by shoulders 17 and 18 which fit between the frame-sides. Lever 13 is normally positioned at the front and extends normally downwardly, so it will not interfere with the use of that portion of the table or counter adjacent the frame. A cork-screw carrier 19 and a nut 20 are longitudinally movable in the frame and are pivotally connected with crank 16, and an integral laterally projecting stud 24 pivotally connected with carrier 19. Crank 16 is arranged so as to swing up and down to operate the carrier in both directions by continuous movement of the lever in one direction. A stop 25 is engaged by crank 16, when lever 13 is in normal position, to limit movement of the lever in one direction.

A cork-screw 27 has its upper end journaled in the carrier 19 and extends through a correspondingly shaped channel in nut 20. A pocket 28 and an open recess 29 are formed in carrier 19 and therein are respectively held a head 30 and a shank 31 of the cork-screw. A ring or washer 32 encircles the cork-screw shank, between head 30 and the lower edge of pocket 28, and forms a bearing-surface for the head when the carrier is shifted in upward direction. The upper end of the cork-screw is tapered or reduced to enter a seat 33 in the carrier, against which said end bears when the carrier is shifted to drive the cork-screw downwardly. Head 30 fits loosely between its bearing- surfaces 32, and 33, and can be placed in operative position in the carrier by first inserting the tapered end into seat 33 with the corkscrew in angular position shown in dotted lines Fig. 7 and then moving the corkscrew so washer 32 will overlie the lowervportion 34 of the carrier, and so shank 31 will be held in recess 29. Manifestly the corkscrew can be quickly and readily placed in position in the carrier and can be readily replaced if broken.

During operation of the corkscrew to draw a cork, nut 20 which is non-revolubly held in the frame, is caused to travel in unison with the carrier and corkscrew, to secure the corkscrew against reverse gyration. To insure this unison movement during the drawing operation, operating link 22 is provided at its lower end with an integral latch-arm 22 having a laterally projecting lug 40 arranged to pass beneath an opposltely projecting lug 41 of nut 20 and thereby the nut is shifted longitudinally with the operating link and corkscrew during the shift .of the corkscrew to draw a cork and during descent thereof to lower the cork into position for stripping. Lug

of the carrier by the operating link (see Fig. 2)" said lug will cause combined upward movement of the nut and carrier. During reverse shift of lever 13, when nut 20 reaches its lowermost position, operating link 22 will be swung to free lug 40 from the nut, so the corkscrew during the next succeeding upward shift, will be ro tated and drawn out of the cork. It will thus be seen that lug 40 serves as locking means between the carrier and the nut, that arm 22 serves as a connection between the link and said locking lug, which causes the link to operate the lug into and out of position to engage the nut.

' An important resultant advantage of the 'mechanism thus far described, is that the operating link which imparts movement to the corkscrew-carrier also efiects unison movement of the'nut and carrler, without employment of a separate interlocking element between the carrier and the nut and controllin means for operating the interlocking element. Oscillatory movement of the carrier-shifting-link, imparted thereto bythe operating crank is utilized to cause unison movement of the corkscrew and nut.

A lock for securing the nut against longitudinal movement with the corkscrew, when a drawn cork has been lowered and the r corkscrew is to be withdrawn from the cork,

the nut for longitudinal movement.

consists of a bolt 45 seated in a recess 46 in one side of the frame and held by lugs 47 48 and 48 so it can be swung laterally. Nut 20 is formed with an integral extension A-n elongated abutment 50 of bolt 45 is arranged to be swung into position to lock the nut (see Fig. 6), against longitudinal movement, and also into position adjacent the frame side (see Fig. 5) to free An arm or lug 51 on bolt 45 is arranged to be shifted by edge 52 of crank 16 during the reverse movement of crank 16, to swing abutment 50 into the path of movement of 1 nut 20. A lug 53 on operating link 22 is arranged to shift, abutment 50 during the initial downward movement of the carrier, and swing said abutment out of the path of, and release the nut. The upper end of 7 bolt45 is held in its seat by the hub of crank 16 and its lower end is held by nut-extension 49. The side of nut-extension 49 engages the side of abutment 50 during travel of the nut, to secure the bolt against pivotal I: movement: at that time.

The operation will be as follows: Assuming, the mechanism to be in normal position shown in Fig. 1, with a corked bottle held beneath the frame by hand or otherwise, the operator should swing lever 13 upwardly and backwardly, which will cause crank 16 to reciprocate the carrier and the corkscrew. During downward movement of the corkscrew it will gyrate into the cork.

,Vvhile the carrier is approaching its lowermost position, lug 53 on link 22 engages abutment 50 of the lock and swings said abutment to release the nut. Approximately as crank-stud 23 crosses the dead center, lugs 40 and 41, of link 22 and the nut respectively, will interlock, so that during the succeeding upward shift of link 22 by crank 16, said link will positively shift the carrier and the nut in unison (see F1g. 2) thus securing the corkscrew against reverse gyration, which would cause the corkscrew to be withdrawn from the cork. When lever 13 reaches the limit of its backward movement, the cork will have been drawn out of the bottle. direction and during theinit-ial part of said shift, crank 16 will shift the corkscrew car- Lever 13 is next shifted in reverse rier and nut downwardly to lower the cork. When the crank is near the dead center,

be moved upwardly, by link 22 while nut .20 is secured in its lowermost position, and during such operation the cork will be stripped from the screw.

In Fig. 10, there is shown another form of nut-lock, which consists of a dog 7 O pivoted at 71 to the nut.

Said dogis adapted to pass beneath a lug 73 011 the case to secure the nut against upward longitudinal movement, and is provided with an arm or abutment 72, arranged to be engaged by a lug 40 of operating-link 22 to release the dog, so the nut will be free to move upwardly, during the withdrawal of the cork. In this form of the invention the operating-link during its initial downward stroke passes into position seen in Fig. 10, and as the operating-link is moved across the dead center, lug 40 will swing dog about its pivot, so it will be freeto move vertically,

ing the succeeding upward shift of the operating-link the nut will be secured in its lowered position to strip the cork from the corkscrew while the carrier is being independently Operated to shift the corkscrew. In this construction it will be observed, the operating-link is utilized to operate the nutlock and to operate the nut in unison with the corkscrew during a part of the travel of the corkscrew.

It will be observed that the operating link is connected to the carrier at one side of and near the lower end of the carrier. and that the carrier is cut away or formed so the upper part of the link can be swung across a line extended through the axis of the corkscrew. This construction and arrangement are important because it makes possible-a compact construction, so the size of the machine can be materially reduced. Furthermore, by reason of such construction it becomes possible to use a link which is connected at one side of and near the lower end of the carrier, without having the lever swing entirely at one side of the cork-screw or carrier to clear such parts, which arrangement is objectionable because the power is not advantageously applied to the carrier,

and results in objectionable lateral strains as the lever swings through its operative arc.

Manifestly, the'details of construction set forth may be modified within the scope of the appended claims without departingfrom the spirit and scope of the invent-ion.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is:
