Abstract: 16,659. Lucas, G. Aug. 19. Measured quantities, delivering. -- Relates to bottles which cannot be refilled after having been once emptied, the stoppering arrangement being such that the contents can be withdrawn in measured quantities, while, after a predetermined number of such quantities have been poured out, the stopper becomes locked in the closing position. The stopper may be of any form suitable for allowing the contents to be poured out in measured quantities. The form shown comprises two closefitting plugs or pistons B', B<2>, connected by members B<3>, and adapted to slide in the neck. When the bottle is inverted, the space between the plugs becomes filled with the liquid, and, as the plugs descend towards the mouth of the battle, the plug n<2> closes the neck, white the plug B<1> uncovers a suitable port, permitting the outflow of the entrapped portion of the liquid. When the bottle is returned to the upright position, the stopper falls to its original position, shown in Figs. 1 and 5. The arrangement shown in Fig. 1 for locking the stopper comprises a wheel D fixed to the plug B<1>, and capable of rotation by a spring on the fixed shaft G, the stops E on the wheel being engaged successively by the projection 0 in the fixe j casing H, which also carries the shaft G. The stops E are arranged in two series, the members of the upper series alternating with those of the lower series. When the bottle is inverted, the projection C releases the upper stop with which it is in contact, and engages the next stop of the lower series. Similarly, when the bottle is returned to the upright position, the lower stop is released, and the projection 0 engages the next step of the upper series. Thus, each time a portion of the contents is poured out, the wheel D is rotated through the space between two of the stops in the upper series. After the predetermined number of operations, the projection C engages under a horizontal projection on the wheel, and locks the stopper in its upper closing position. The casing H may be secured by spring catches H<1> engaging in recesses H<2>, or by other suitable means, so that it cannot be withdrawn without breaking the neck. In the form shown in Fig. 5, the catches H<3> and recesses H<4> are of a different shape, and a base-plate H<5> is provided on the casing to prevent tampering with the escapement. The lower portion of the neck may be made narrower than the upper portion, the shoulder L so formed serving as a stop to limit the insertion of the casing. The stops E<2> are arranged on the casing H, while the projection C<1> is pivoted on the shaft G<1>, and moves vertically with the stopper, which is prevented from rotating by the squared lower portion of the shaft. The rotation of the projection C<1> is effected by a spring carried by the post K on the stopper. Fig. 9 shows in development another arrangement of stops, the block C<3>, which is carried by any suitable reciprocating part, traversing the grooves between the projections E<3>, until it is finally locked by the stop E<5>. In the form shown in Fig. 12, the ribs E are arranged on the member D', which is rotated by the spring F<3>, the ribs being engaged by the stop projection C<5> on the post K. The stopper B' slides on the shaft G', and is finally locked by the projection EG.
