The object of this invention is to furnish dies for-forming curved spouts for oil-cans and other uses, which will enable the said spouts to be formed rapidly, accurately, and neatly, and at much less expense than when formed in the usual way.
The invention will first be described in connection with drawing, and then pointed out in the claim.
Curved spouts have heretofore been made by making a straiglit spout, running it full of lead, bending it into the desired form, melting out the lead, and afterward retinnin g the spouts. This mode of construction is tedious, and makes the spouts expensive.
I will describe my improved dies in connection with the operation of forming a spout.
A represents the blank out of which a spout is to be formed, and which is out out of sheet metal into the required shape and size.
The blank A is laid upon the face of the die B, and is brought into the exact position by guide-pins b attached to the face of the said die. The die 13 has a slot, b formed through it, through which the blank A is forced by the flange c of the upper die 0. The face or edge of the flange c is concaved, as shown in Figs. 8 and 4, so that the blank A when itcomes from the dies B 0, may be in the form of a curved half-tube, as shown in Figs. 3 and 4. The blank A is then put upon a former, D, of the exact size and shape of the required spout, and which-is provided with a handle, all, and is pivoted to the end part of the die E. In the face of the die E is formed a groove, 0, which is curved into the exact form of the concaved side of the required spout,.into which the former D and blank A are lowered, and in which the said blank is operated upon by the die F. In the face of the die F is formed a groove, f, which is curved into the exact form of the convex side of the required spout. In the bottom of the groove f is formed a shoulder of a height equal to the thickness of the plate of which the spout is being formed. As the die F is torced downward it presses the edges of the blank A inward until one edge strikes the shoulder of the groove f, and the other edge slips-past and underlaps it, thus forming the blank A". The die F is then removed, and the die G is forced down upon the blank A while still upon theformer D,and in the groove 6 of the die E. The die G is made with a groove, g, like that of the die F, except that it has no shoulder, and closes the overlapped edges of the blank A down upon each other, forming the spout A which only required to be soldered to form a finished spout.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of the series of dies B (J E F G with the former'D, the die-faces having a longitudinal curve corresponding to that of the former, substantially as and for the purpose specified.
J OHN GILBERT.
