SAME PLACE.

BOTTLE-8T0 PPER.

SPEGIFIGATION forming part of Letters Patent No. 564,732, dated July 28, 1896.

Application filed July 5,1895. Serial No. 554,925. (No model- To all whom it may concern:

Be it known that we, HARVEY P. BARNHART and SAMUEL L. BARNHART, citizens of the United States, residing at Potsdam, in the county of St. Lawrence and State of New York, have invented a new and useful Improvement in Bottle-Stoppers, of which the following is a specification.

This invention relates to that class of bottlestopper fasteners which comprises a swinging bail or yoke pivoted to the neck of the bottle and a clamping-can carried by the bail and adapted to bear upon the cap or stopper, and more particularly to a fastener of this kind which is especially desirable for milkbottles that are closed by a separate cap or disk, such, for instance, as is shown and described in Letters Patent of the United States granted to us September 17, 1889, No. 411,368.

Our invention has for its object to produce a reliable and inexpensive fastener of this character which can be easily manipulated.

In the accompanying drawings, Figure 1 is a fragmentary side elevation of a milk-bottle provided with-our improved fastener. Fig. 2 is a similar view at right angles to Fig. 1. Fig. 3 is a top plan view of the same. Fig. at is a perspective view of the bail and cam detached from the bottle.

Like letters of reference refer to like parts in the several figures.

A represents the neck or upper portion of a milk-bottle, and B is the cover or stopper, consisting, preferably, of a thin ligneous disk or cap, such as is described in our Letters Patent hereinbefore referred to. This disk is seated in a shallow annular recess 0, formed in the upper end of the bottle, whereby the disk is held against lateral displacement.

D is the swinging bail or yoke, having its side members provided with the usual horizontal pivots, which are preferably journaled in sockets or indentations formed in the neck of the bottle, as shown in the drawings.

E is a cam carried by the swinging bail and adapted to bear upon the cap or disk, so as to hold the same firmly upon its seat. This cam consists of a pair of substantially parallel upright members or branches e, having their upper portions connected by a bend or bow 6, whereby the cam is pivoted to the bail.

passing through the cross-bar of the bail when the latter is in its normal posit-ion, as clearly shown in Figs. 2 and 3. The feet of the depending members thus give the cam a considerable bearing area on opposite sides of the bail, whereby the latter is effectually held against swinging in either direction.

g is a stop or cross bar which bridges the space between the depending members of the cam at or near the lower ends thereof, and which is adapted to come in contact with the cross-bar of the bail when the cam is swung upward for releasing it, so as to limit the movement of the cam when raised sufficiently and thereby prevent its swinging into an inoperative position.

The cam is preferablybent from a single piece of wire, in which case the feet of the cam are formed by bending the wire into the shape of scrolls or rings, and the end portion of one of these scrolls is extended across the depending members of the cam to form the stop g, as shown in Fig. 4.

In applying the cap or disk to the bottle the bail is swung to one side of the bottle in the usual manner, and after inserting the disk the bail is swung over the cap, the cam being raised sufliciently for this purpose. The cam is then allowed to swing down and forced for- ,ward into its locked position, as shown in ing the cam rearward, so as to unlock it, as

shown in Fig. 1, when the bail can be swung clear of the mouth of the bottle.

While we prefer to employ a thin disk-like cap of wood or paper-board for closing the bottle, it is obvious that our improved fastening may also be used with a glass or metallic cover.

We claim as our invention 1. The combination with a bottle or jar having a cap or stopper, of a swinging bail having a cross-bar, and a clamping-cam carried by the bail and consisting of a pair of depending branches or members connected at their upper ends by a bend or bow pivoted to said cross-bar and arranged at right angles thereto, said depending members standing on opposite sides of the bail and each terminating in a horizontal ring or loop forming a foot or enlargement, which bears upon the cap of the bottle, substantially as set forth.

2. The combination with a swinging bail having a cross-bar, of a cam consisting of a single piece of wire doubled upon itself to form a pair of depending members or branches and having the bend which connects said branches pivoted to the cross-bar of the bail and arranged at right angles thereto, said branches standing on opposite sides of the bail and each having its lower portion bent into a horizontal ring or loop forming a foot which bears upon the cap or stopper of the bottle, substantially as set forth.

3. The combination with a swinging bail,

of a cam consisting of a piece of wire doubled upon itself to form a pair of depending members or branches and having the bend or bow which connectssaid branches pivoted to the bail and arranged at right angles to the crossbar of the bail, said branches being provided at their lower ends with feet or enlargements adapted to bear upon the cap or cover of the bottle and one of said feet being formed with a stop or extension which bridges the space between said branches, whereby the upward swing of the cam is limited, substantially as set forth.

\Vitness our hands this 17th day of June,

HARVEY P. BARNHART. SAMUEL L. BARNHART.

O. E. SANFORD, F. M. PECK.
