NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 568,243, dated September 22, 1896.

Application lledIebruary 29,1896. Serial No. 581,238. (No model.)

.To @ZZ whom it may concern.-

Be it known that I, WILLIAM R. FEARN, a' citizen of the United States, residing at Camden, in the county of Camden and State of New lIersey, have invented certain new and useful Improvements in Non-Refilling Bottles, of which the following is a specication.

My invention relates to a new and useful improvement in non-refilling bottles, and has for its object to provide such a device that will overcome the difficulties which have heretofore been experienced in the manufacture of such bottles and also to increase the safety of this class of devices by-providing a a seat which will better adapt itself to the valve.

With these ends in view my invention consists in the details of construction and combination of elements hereinafter set forth,and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction and operationin detail, referring by letter to the accompanying drawings, forming apart of this specification, and in which-- Figure l is a central section of a portion of a bottle and its neck, showing my improvement applied thereto; Fig. 2, a detailed perspective of the guard-disk, showing the relative position of the spring-prongs; Fig. 3, a similar view of the cap, and Fig. 4 a similar view of the cage which serves to retain the valve in its proper relative position to the valve-seat.

Referring to the drawings, A represents the bottle, and B the neck thereof, in which latter is placed a plug C, preferably of cork, having a central opening D, the upper portion of which is flared and serves as a valveseat foi-the valve E. This valve is preferably of spherical shape and made of glass.

F is an annular groove formedin the inner wall of the neck and adapted to receive the spring-prongs G and H of the guard-disk I, which latter is preferably made of asingle piece of metal so blanked and bent. as to form Upon the under side of the disk I is placed a cap J, having a ange K, through which a number of holes L are formed, so as to permit the `free passage of the liquid, and Within this cap is placed the disk M, provided with a number of depending arms N, so arranged as to form a cage for the purpose of limiting the movement of the valve E and preventing it from falling out of line with the valve-seat. "The guard, cap, and cage are secured together by a rivet O, passed through the central ,hole formed in each and headed, as clearlyA shown in Fig. l.

In practice the bottle is first filled with the desired liquid, the plug C then forced in place, the valve dropped upon its seat,and the guard carrying the'cap and cage pressed into the mouth P until the prongs H come in contact with the shoulder formed by the annular groove, when sufficient force is brought to bear upon said guard to spring the prongs H outward and permit the prongs G to snap within said groove. By this Ineans the guard is firmly held against removal, thereby protecting the valve again'st interference.

In manufacturing the bottle the only essential feature to be considered is that the groove F be properly located and of the proper dimensions; but I also prefer to have the mouth of larger diameter than that portion of the neck immediately below said mouth, in order that when the guard is forced into said place the prongs H will come in contact with the shoulder formed by the construction of the neck, and also because it permits the overlapping of the lianges K past the edges of this shoulder, which latter serves as an additional safety against the valve being tampered with by the passing of a wire around the guard and between the shoulder and flange. The advantages of this construction are that the valve-seat is formed separate from the bottle, and therefore may be more perfectly made and at less expense, and as this valve-seat is formed of a yielding material it follows that the valve will seat more snugly thereon, and also that the cage so limits the movement of the valve when the bottle is tipped to one side as to facilitate its return to the seat.

The operation of my improvement is as follows: After the bottle has been filled and properly sealed, as before described, the contents may be withdrawn therefrom in any quantities by tipping the bott-le to one side IOO in the usual manner, and when so tipped the valve E will move from off its seat into the cage, thus permitting the liquid to iiow through the central opening D and perforations L around the guard-disk I and out of the mouth; but should an attempt be made to refill the bottle the inflowing liquid would pass around the guard, through the perforations, and into the space between the guard and plug, where it would be prevented from passing into the bottle by the closing of the valve onto its seat, and as this seat is of a yielding material, preferably cork, it will be seen that no amount of pressure put upon the liquid will force it past the valve. Therefore, when a bottle has once been lled,4

sealed, and emptied it becomes worthless in that it may not again be lled for further use.

Having thus fully described myinvention, what I claim` as new and useful is- 1. In combination with a bottle-neck having an inner annular groove, a guard composed of a disk having upwardly and downwardly extending` prongs to engage the upper and lower walls of the groove, a cap having a perforated iiange, and a disk having depending arms, the flange of the cap being adapted to extend below the edge of the shoulders formed ou the inner wall of the neck, a valve-seat arranged in the neck and a valve resting on the seat and controlled by the arms of the disk, as and for the purpose described. i

2. In combination with a bottle of the character described having a suitable valve-seat located within the neck thereof, of a valve adapted tot said seat, of a guard-plate having sprin g-pron gs projecting therefrom, a cap having perforations through the iange thereof, and a cage for limiting the movement of the valve, the said guard, cap and cage bein g secured together, the prongs of the former adapted to engage with the groove, substan- Jrially as shown and described.

In combination with a bottle having a valve-seat, valve and annular groove, as described, a guard composed of a disk, springprongs projecting upward and downward from said disk, a cap havin ga flange through which are holes, and a cage composed of a disk with depending arms, said guard, cap and disk being riveted together, substantially as and for the purpose set forth.

In testimony whereof I have hereunto affixed my signature in theprescnce of two subscribing witnesses.
