C H'ARG ER FO R' POWDE R-FLASKS.

SPECIFICATION forming part of Letters Patent No. 231,533, dated August 24;, 1880. Application filed April 26, 1880. (N model.).

To all whom it may concern Be it known that we, GEO. A. OAPEWTELL and GEO. D. CAPEWELL,.of Woodhury, in the county of Litchfield and State of Connecticut,

have invented a new Improvementin Powder- Ohargers; and we do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and

[O exact description of the same, and which said drawings constitute part of this specification, and represent, lIl-- Figure 1, sectional side view; Fig. 2, reverse side view; Fig. 3, rear or lower gate detached. I5 This invention relates to an improvementin chargers for powder-flasks and like purposes.

It is desirable that the charger should be of a capacity for the smaller charge; hence, by the usual construction, the tube is only made ofa diameter which will, in a convenient length, give that smaller charge. Oom bined with this is an adjustable tube of substantially the same diameter, so that the increase by extending the two is slow, and for the greater charge requires an inconvenient length of tube, so that it is difficult, in a single charger, to attain the desired range of variation.

The prime object of this invention is to overcome this difficulty; and it consists in the construction, as hereinafterdescribed, and particularly recited in the claims.

A is the tube proper, which is attached to the flask or pouch, its internal diameter and length being substantially that usually em- 3 5 ployed, and which gives the minimum charge. The outer diameter, however, we make very much greater than the usual construction, and this we do, preferably, by thickening the sides a. Then over this enlarged tube we arrange the sleeve B in the usual manner, but, of course,

of greatlyincreased diameter, and make it adjustable on the inner tube by means of a slot, b, and set-screw G, or otherwise.

D-is the gate-lever, which is hung upon a 5 pivot, d, on the inner tube, as seen in Fig. 1, and provided with a spring, E, the tendency of which is to force up the rear end of the lever and the forward end down, as seen in Fig. 1, in the usual manner for chargerdevers.

so The rear or cut-off gate, F, plays through a sl0t,f, in the inner tube, and is hung to the rear end of the lever by means of a hook, h. This hook passes through an opening, a, in the gate F, (see Fig. 3,) the gate extending up onto the lever and in rear of a stud, m, on the lever. The object of this stud m is to keep the gate parallel, or prevent its turning from its proper position, or catch or interfere with the play of the lever, which it will do it simply hinged to the lever.

In operation, when the lever is depressed, the stud m strikes upon the back of the gate, above the hinging-point, and tends to throw the lower end of the gate forward and close against the lower end or shoulder of the tube A, and it prevents the possibility of the gate tipping out of its proper working plane. The other or outer gate, H, extends through a slot in the outer tube, and is hung in a slot, L, of the lever D, and so that the hinging-point may be easily moved along the slot; but it left free to so move the same difficulty will occur as described for the other gate-that is, it is liable to clog or so tip as to prevent its proper working.

To avoid this we attach to the pivotbearin g a frictional spring, N, which, while it will allow the pivot-bearing to be easily moved in the slot L, will retain that hearing at the point to which it may have been moved.

The outer tube is moved outward, so as to extend the length of the charger, in the usual manner, the pivot-bearing of the gate H moving in the slot L a corresponding distance. Because of the much greater internal diameterof the sleeve B (its area being about double that of the tube A) it follows that the movement or extension of the sleeve B will be proportionately less than it would be were it of a diameter corresponding to the tube A as usually constructed; hence the maximum quantity is measured with a proportionatelyless movement of the tube, enabling the charger to measure between the two extremes, and yet without extension greater than that employed for from 9 5 medium to minimum charge or from medium to maximum.

The interior of the tube A is inclined so as to bring its mouth eccentric or near the side from which the gate H opens, as seen in Fig. 109

1, because in that position the full capacity of the tube A is opened, which it could not be if it were concentric without a greater movemeutof the lever-that is to say, the upper or forward gatemust come to abearingin the outer tube upon the side opposite the slit through which it works. Therefore, by making the opening of the tube A at the outer end eccentric, or upon the side opposite the slit, the raising of the outer gate opens it from the start, and requires a movement only equal to the diameter of that opening, whereas, were it concentric, the movement of the gate must be so much greater as to carry the gate to the opposite side of the opening.

We claim- 1. Theinner tube, A, having its mouth eccentric to the external diameter, combined with the outer adjustable tube, B, with the lever D,

hinged gate F, and adjustable gate H, substan- 2o tially as described.

2. The combination of an inner tube and outer adjustable tube, the slotted lever D, hinged gate F, the gate H, hinged to a bearing in the slot of the lever, with africtional spring, N, on 25 said bearing and in said slot, substantially as described.

3. In a charger, substantially such as described, the gate hung to a hook on the lever, with a stud, m, on said lever above the hing- 0 in g'point of the gate and back of the gate, substantially as and for the purpose described.
