SPECIFICATION forming part of Letters Patent No. 505,920, dated October 3, 1893.

Application filed March 10, 1893- To all whom it may concern:

Be it known that I, HARRISON S. MARTIN, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Cork-Extractors, of which the following is a specification, reference being had therein to the accompanying drawings. 7

Figure 1 is an elevation from the rear of a device embodying my improvements. Fig. 2 is a view showing the interior parts of the casing being divided, and some of the contents being shown -in section. Fig. 3 is a similar view of the other part of the casing. Fig. 4 is a section of the casing taken at right angles to Figs. 2and 3. Fig. 5 is afront view. Fig. 6 is a section on the line :20, 00, of Fig. 5 and on a larger scale. Fig. 7 is a sectionon the line y, y, ofFig. 5. Fig. 8 is a side View of the bottom part of the device. Fig. 9 is a perspective of the nut and its plate. Fig. 9 shows detached, the cam plate for moving the nut and holding it in its operative position. Figs. 10 and 11 show a modified form of extractor.

Acasing or tube is constructed in such "way as to properly support the corkscrew and the parts which operate it and also the parts which hold and support the bottle, this casing being made in two halves or parts A, A, so asto reduce the cost of the implement by avoiding the necessity of coring in casting. The two halves of the tube or casing are firmly joined together by suitable devices such'as a screw cap a. at the top and ears a, a, which are fastened together by screws, as at a The casing parts are so shaped as to provide a slot B in the rear, and a slot 0' epposite thereto in the front side, and also slots D in the sides, and these serve purposes to be described below.

A indicates the base piece or pedestal by means of which the implement can be firmly fastened to the table, or other support, and which may be cast integral with one of the casing parts A, A, or cast partly with one half, and partly with the other. The walls of the interior chamber are flared somewhat at the bottom, as shown at b.

E indicates the cork screw, it being secured to, or formed with the screw stem or shank which rotates it. Preferably it is inserted Serial No. 465.438, (No model.)

into the lower end of the screw F. This screw F is mounted in a vertically sliding frame or carrier G, which is formed with the rear upright bar g, the bottom cross plate g, the top plate 9 and the cam plate 9 these parts beingpreferably allcast integral. The rear Vertical bar 9 has rack teeth g and with these a toothed wheel orsegment H engages, the shaft of which wheel is mounted in a bracket I which extends back from the tube or casing.

J indicates a handle which is secured to the wheel or segment H, and by which the latter can be rocked in such way as to throw the frame or carrier G up and down in the casing. The carrier G is formed with bearings in' the top and bottom plate and g for the mounting of the screw so that the latter is free to rotate relatively to the carrier, and can at the same time be moved bodily up and down with it.

The interior of the rack frame is hollow, or open, and is therefore adapted to permit an advantageous arrangement of the nut which is placed within the said chamber, as will be explained, that is to say the nut can be placed between the ends of the rack frame, vertically. Asthe carrier Gand the screw F move L is a nut of the-nature of a pin or short arm projecting outward from one of the casing walls. This nut pin is carried by a plate L, having the guide-part Z anda shoulder at Z. The part Z is fitted in a guide-way formed by ribs 41, 01., upon one side of the chamber within the casing. The part Z is shorter than the guide-way so that the plate and nut pin can slide to some extent. The shoulder at Z is so situated that the plate can be engaged by the cam part g of the vertically sliding frame G, and when such engagement occurs, the nut pin L will be held rigidly in position at the point where it engages with the screw F.

The actions of the parts described will be readily-understood. As the carrier G descends the screw F will be rotated because of its engagement with the nut pin L, and such rotating of the screw causes the corkscrewE 'toperforate and enter the cork in the bottle. But when the movement of the carrier G is reversed and it is thrust upward the pressure of the thread on screwF will compel the nut pin L to move laterally out of engagement with said thread, the part Z of the nut plate being shorter than the guide-way at 'lt n to permit this escaping motion of the nut; and

5 therefore during the first part of the upward motion of the carrier G neither the screw F nor the corkscrew E will be rotated, and hence the cork will be drawn from the bottle. But as soon as the cam plate q comes in contact with the shoulder Z of the nut plate, the

latter will be moved back along the guideway formed by the inclined guides at n, and held in such position that it is compelled to engage with the thread of screw Rand the latter commences to rotate and continues to so rotate during the latter partof theupward travel of the carrier G. This'rotation is in adirection opposite to that of the rotation during the descent and therefore thecork screw, E will be drawn out from the cork.

Forthepurpose of holdingth'e bottle firmly during the operationlof drawing the cork,I,1 employ laterally movable jaws N, N,so situ-l ated that theycan be adapted to surround} more or less of the neck of the bottle. They: are moved by bars 0,0 with which engage lugs P that are carried by the plungeror can '1 rier G. As shown there is an arm p'qwhich projectsthrough the slot Of, and'has across piecep for supporting these lugs. The bars 0 O are preferably more or less elastic so i that they can act to open the jaws N, and}; also can applya yielding pressureytolthe jaws as the lugs P movedown. i j, M is a stop plate which can rise and fall; within certain limits in the bottom partofthe chamber in the casing, it having projections D which jfit in the slots D. This plate moves up with the cork as the latter rises, 40 but stops it at the proper point to have the screw withdrawn.

' Asomewhat modified form of the extractor is shown in Figs. 10 andll. Here the nut L isattached to a sliding carrier L, which has ribsor projections that fit in groovesor slots D in the sideof the casing. It alsoycarrieseye-pieces P or lugs, whichengage withj the jaw-supports or carriersO O. The jaws,

N are not pivoted asin Figs. 1 to 4, but'can 5o move out andininasmuch as the spring parts support them entirely. The upper portions 0 of the jawcarriers are elastic, audat 0 there are cam-like shoulders, andwh en the 1- nut carrier L moves down, the eyes P en 5 5 gage with these shoulders and force the jaws N inward,so,as to grasp the bottle neck, and theyare held in until the nut carrier has reached again the upper .end of its play. The nut carrier in this case is somewhat dif- 6o ferent from the plate used in theother construction,it here consistinglof avertical bar, with a nut projection at L which compels the screw F to rotate at the times that the carrier L is stationary, attheupper and the lower 6 ends ofthe slots D.

I have found that a nut projection of the character of that shown at L or L is much superior to those which entirely encircle the screw, as the latter have enlarged wearing and bearing surfaces .which increase the friction, and, moreover, unless the parts are fitted very accurately by expensive labor, they frequently tend to bind or cramp in the casing, and in turn, bind upon the screw. A nut like that at L cannot cramp or bind, or become clogged with grit or dirt, or be seriously worn, as it and the thread or groove in the screw are practically self clearing. By having thenut situated inside of a rack frame or carrier like that at Gr which is hollow or formed with an interior nut chamber, and is movable independently of said carrier, I am able to shorten p the mechanism as a whole, and make it more compact than are those which are so arranged as to requirethat one -or more nutsbesituated aboveor belowthe rack frame.

Thespring carriers OCQrO fOr the jaws N v or N provide am uch simpler means for-open- 'ing and closing the llatterthan those usedxin theearlier constructions, as the parts 0, can, of themselves, perform jbothlof the above described functions, namely ;imparting inward movement to the jaws, and holding thei-latter under a yielding pressure; ,lEleretoforetemployment has been made uof a complicated mechanism foraccomplishing this purpose it comprising two or more hinged levers, and sliding wedges supplemental to the spring parts. In the present. construction two spring bars and aJug arelall that are necessary.

What I claim isr 1. In}a cork extractor,-the combinationwith the tubular-casing, the-rackframmthetoothed wheel for positively lifting and depressing the;frame,the screw mountedrtherein,-the;nut adapted to slide from one horizontal line to another, and means carried by the rack frame for'moving the nut toits operativelpositions, of the Verticallyarranged elastic spring carriers secured rigidly to the casing and extending downward by the side 1th ereof,the aws N connected to the said spring1 carriers, and lugs 0 bearing directly against theouter sides of the spring carriers and adapted to bend them, substantially as setforth.
