To all whont it may concern:
Be it known that I, FRANCIS DE Gonna, of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Tops for Flasks;
and I hereby declare that the following is a full, clear, and exact description of the same,
reference being had to the accompanying drawings, formingpart of this specification.
The metal tops for flasks are usually secured by a hinge-ring to the neck of metal flasks or to a metalsleevesecured to the neck of a glass or other flask. have heretofore been made of a number of parts which were secured to each other by.
solder. The cup in which the cork is held was soldered to a sleeve on which the hinge, ring turned, and a sleeve provided with the projecting screw-thread sections and having a flange at the lower end was secured by solder or brazing in the ring-sleeve. This construction is expensive and the'topso made is weak, the soldered joints forming a number of weak points.
The object of this inventionisto secure a more durable and a cheaper flask-top; and to this end the invention consists inthe peculiar and novel construction whereby the flask-top is made-complete outof one piece of sheet metal without the use of solder or brazing, as will be more fully set forth hereinafter.
Figure 1 is a side View of a cup drawn up from sheet metal; and Fig. 2 is a sectional view of the same, illustrating the first step in the manufacture of the flask-top. Fig. 3 is a sectional view showing the next step in the manufacture of the flask-top- Figs. 4c and 5 are sectional views illustrating the next successive steps, and Fig. 6 is a sectional view of the completed flask-top. Fig. 7 is a side view showing aflask provided with the improved top, and Fig. 8 is a sectional View of the same.
In the construction of myimproved flasktop 1 form the cupishown in Figs. 1 and 2) from a sheet-metal blank and then by spin ning the metal cup produce the head a, as shown in Fig. 3, and continuing the spinning form the annular head I), as shown in Fig. l,
top may'freely These metal tops and the sleeve 0. I now place on a suitable die and with a contractible outer die force the -metal forming the inclined Ways (1 d inward.
The hinge-ring eis now placed over the sleeve 0, and the lower edge of the sleeve 0 is burnished or spun outward to form the flange f. The hinge-ring is thus secured to the top be tween the head I) and thetlange f, so that the turn in the riii'g'c. q is now pressed intothe'head a of the top,
and the inge-ring c is secured to the hinge .on the neck-7t.
" A top for flasks constructed in this manner ,is much more durable than one constructed in parts and soldered orbrazed together. As the metal is not subjected to heat in soldering, it is stiffer andstronger. The top is secured to the neck by passing the latch t of the neck in between the inclined ways (1 d and rotating the head so as to draw the cork 9 onto the end of the neck, thereby closingthe outlet.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent v In a top for flasks, the combination with the metal neck secured to or forming part of a metal flask, of inclined ways formed on the contracted upper portion of the metal neck, the part of the hinge projecting from one side of the metal neck, and a ring provided with a hinge portion pivotally secured to the hinge portion on the metal neck, of the head portion of the top consisting of the head a, the annular outwardly-projecting head I), the
The cork sleeve 0, the inclined ways 62 d, the flangef
