IMPROVEMENT IN CANS FOR OILS AND OTHER LIQUIDS.

Specification forming part of Letters Patent No. 141,224, dated July 29, 1873; application filed May 29, 1873.

To all whom it may concern:

Be it known that I, MARK WIGGINS HoUsE,

of Cleveland, in the county of Ouyahoga and State of Ohio, have made certain new and useful Improvements in the Nozzles of Oans and other Vessels for Holding Liquids; and that the following is a full, clear, and exact description and specification of the same.

The objects of this invention are to afford a free vent for the air in the can while the liquid is poured through the filling-nozzle also, to enable the air-vent and liquid-passage to be through the filling or other nozzle without obstructing the passage of the liquid. To these ends my invention consists of certain combinations of the nozzle of the can or other vessel with other parts, close of this schedule. The invention may be embodied in various forms, depending upon the construction of the vessel to which itis applied and the use of the invention in whole or in part.

In order that it may be fully understood, I have represented in the accompanying drawing, and will proceed to describe, a keroseneoil can with my invention applied to it.

Figure 1 represents a side view of the upper part of the said can. Fig. 2 represents a vertical section of the same. Figs. 3 and 4 represent transverse sections of the filling-nozzle at the lines a" x and y y, respectively; and Fig. 5 represents a central vertical section of the nozzle on a larger scale.

As the body of the can may be of any de sired form, only the upper part, A, of itis represented. This can has two nozzles, B O, the one, B,for fillingit, and-theother, O, which has the ordinary spout form, for pouring out the liquid. In order that the air may be permitted to escape freely while the liquid is poured into the can or vessel A, the fillingnozzle B is divided into two passages, c and d, by means of the partition f. This partition below the exterior wall g, and is held in its position by means of the strips 0, Fig. 4, which extend up and down the outer side of the partition and connect it with the wall 9 of the nozzle. The inner passage d serves for the which are specified at the entrance of the liquid, and the outer passage 0 for the passage of air; and, as the partition f extends below the internal mouth h, by which the air-passage communicates with the interior of the vessel A, the entrance of the liquid cannot interfere with the free passage of the air from the vessel into the internal mouth. In order that the external mouth of the air vent or both be closed by the same bung or stopper, the wall g of the nozzle is extended above the partition f, and is constructed with an inwardly-projecting rim, n, or flange, so that its internal diameter is contracted to one not materially greater than that of the liquid-passage d. Consequently, aslightly conical bun g, such as is represented by the lines K, can be readily introduced into the nozzle, and, when so introduced, will simultaneously close both passages. The internal rim n also acts incidentally to strengthen the orifice of the nozzle; and to this end I prefer to make it by turning the thin metal of the nozzle over a wire ring. If preferred, a cap, T, may be used in addition to the bung, or without the bung, to close the nozzle, the absence of any external projection at the orifice of the nozzle adapting it to be thus closed; and, if preferred, the nozzle may be slightly conical, with the smallest end outward, so as to enable a cap of corresponding internal form to be tightly applied to it. In order that the interior of the can may be protected from the entrance of flame by the nozzle, a flame-guard, L, composed of a thin strip of corrugated metal wound into a volute, is applied to the inner orifice of the liquid-passage d. The air-vent 0, also, is made of small breadth, and if circumstances require this breadth to be made so great as to admit flame, a similar flame-guard is applied to it. In order, moreover, to prevent the flame-guard from obstructing the free entrance of the liquid, it is made of greater transverse area than the nozzle, and is secured in an enlarged chamber, M, so that the combined areas of the passages through the flame-guard afford a free passage for all the liquid that can be poured into the external liquid-passage d. The flame-guard is held in place by means of small bars .9 secured to the wall of the enlarged chamber M. The improvement last described is represented at L M as applied to the spout or deand the internal flange at the exterior mouth livery-nozzle U of the can, so that the spout of the nozzle.
