BQTTLE-STOPPERH Specification of Letters Patent. Application filed-April 30, 1906. Serial No; 314,426.

To all whom it may concern.-

Be it known that I, WILLIAM H. Down, a citizen of the United States, residing at the city of New York, in the borough of Brooklyn and State of New York, have invented certain new and useful Improvements in Bottle- Stoppers, of which the following" is a full, clear, and exact description.

My invention relates to bottle, caps or stoppers," particularly to that class in which the cap is normally held to the bottle by cam or other means and is removable or replaceable whenever desired.

The tion is to facilitate the assembling of the various parts when the cap is manufactured.

Withthis and other objects in view'the invention consists in the form and arrangement of the cam-slot, as hereinafter set forth and shown, and finally. particularlypointed out in the appended claims.

in the drawings, Figure 1 is a side view of the bottle-cap embody ng the principles of my invention. Fig. 2 is a similar view showing the cam in position to be assembled upon the other parts. Fig. 3 is a detail sectional view of the clamping-handle, showing its re-' lation to the Wire clamping-ring when being assembled thereu on.

in assembling t e parts of the Kirkegaard stopper hitherto used, and particularly the form in which the cam-slot has both of its walls curved and constitutin the ca1n-surfaces, a great deal of difficultylias been found in placing the cam upon the wire ring. For the urpose of assembling the parts more uic y, with greater facility and more 0 eaply, l have devised a construction in which the cam is capable of performing all of the functions that it had hitherto and at the same time may be assembled upon the wire ring by a simple movement, so that the trouble and ex ones of this part of themesess is almost wholly eliminated.

The improvement consists, broadly stated, in enlarging the lower end of the cam-slot to such a size that it will receive one of the hooks at the end of the wire rin by a simple sidewise movement and without any difficult manipulation.

' bottle-cap aving depending fingers 2 and a wire ring 3, the ends 4; of which are bent around to form hooks. 5 denotes the cam,

principal object ofthe present inven-- having acurved slot 6 and a handle :7 i The cam is perforated at 8 to fit upon one ofthe hooks 4.

-. Patented Sept. 1-8, 1906..

Instead of making the lower end of the v curved slot 6 terminate abruptly, as in the usual form, I continue the slot to a point beyond its normal working portion and form an enlar ement at the termlnal end, as shown at 9. he enlargement is preferably elongated in a direction passing through the pivot-point 8. The amount of such elongation correspondsto the amount that the hooks 4: are bent around or turned over.

The use and operation of'the invention are as follows:

The ca s are formed with the wire rings assemble therein by aspecial machine, and the camsare likewise produced in quantities with the slot 6 unched out therein to the proper shape. t is then merely necessary to assemble the cam 5 with its perforation 8 uponone of the hooks 4, the relation at this time being clearly shown in Fig. '3. In this process the cam is held so far tilted up that the elongated hole 9 comes opposite the other hook '4. In this relation the direction of elongation of the hole 9 corresponds to the length of the hook 4:, so that the cam slips over the hook by a simple sidewise movement. The handle 7 is then depressed, which causes the cam-slot '6 to move downward on its hook4 until the ring and fingers '2 arrive at their normal or untensioned state. This condition corresponds to a middle position of the cam-slot 6 upon its hook, so that there is no liability of the hook to ever reenter the elongated hole or extremity 9 of the slot. The corners 10 of the slot at the point of its junction with the elongated hole 9 are, however, rounded, so as not to impede the rentrance of the hook into the slot in any case should the hook be accident ally displaced into the elongated hole.

Whenever the cap is used, it is laced on a bottle and the cam-lever 7 pushe downward uniform widt a cam havin a curved slot of substantially I] throu hout its middle portion to engage one of said hooks, and having an enlar ement at the end of said slot to facilitate 5m assembling of the cam upon the ring. 2. In a bottle-cap havin depending fingers and a clamping-ring wit hooks thereon,- a cam he a curved slot of substantially uniform throughout its middle portion and a perforation respectively adapted to receive said hooks, the extremity of said slot bejin enlarged to form an elongated hole, as

and or the p ose set forth.

3. In a bott e-oap ha depending fingets and a olampingqing wit hooks thereon, a earn having a'eurved slot and a perforation adapted to receive said hooks, said curved slotbein formed to receive its hook at about the mid le portion of the slot when the ring and fin ers are in their untensioned state, and sai slet having an enlargement at its lower extremity to form a hole, the width of which corresponds to the length of said hooks. 4. In a bottle-cap depending fi11 gers and a clamping-ring wit hooks thereon, a cam having a curved slot and a perforation respectively adapted to receive said hooks, said'slot bein' ,formed to receive its hook at about its mid e portion in the normal or un tensioned state of said ring and fingers, and said slot being formed at its lower extremit with an elongated enlargement having roun ed corners at its g'unction with said slot, the

= elongation or sai enlargement lying in a direetiontoward said perforation, as and for the purpose set forth.

In witness whereof I subscribe my signature in the presence of two witnesses.
