Be it known that'I, GEORGE E fPAGEfa citizen of the United States, and residing at Rochester, Monroe county, StateofNewl York, have invented certain new and useful Improvements in' Sheet-Metal-Shaping Machines, of which the following is a specification.

The present invention relates to shaping devices for sheet metal articles. The object of the invention is to provide an apparatus by means of which tubular sheet metal members may be suitab-ly curved, for instance, tubular spouts formed integral with sheet metal vessels or containers. In m copending application Serial No. 462,214, led April 18, 1921, is disclosed a method of forming a tubular pouring spout for a sheet metal vessel or container which is integral with the body of the vessel. When the tubular spout has been completely lextruded from the body of the vessel it is only necessary to then cut the end from the extruded nose or projection and to curve the same. It is essential that the curving operation Vbe performed without distorting` the body or destroying its symmetry. To this end have devised a. special press, which is the subject matter of the present invention.

It will be understood that although this press is particularly useful in connection with the curving of the tubular integral spouts of sheet metal c'ontainers it is not limited to this use. On the contrary, it is a machine of general application which may be used for work of widely different character, and is susceptible of considerable modification for different purposes, within the scope of the invention.

In the drawings:

Fig. 1 is a vertical section through the press showing a sheet metal container in position to have its extruded spout curved;

Fig. 2 is a similar viewbut showing the plunger of the press at the completion of its working stroke; and

Fig. 3 is a t'op view of the press, the plunger being omitted.

rlhe press comprises essentially a base member 10, a stationary die 11 and a plunger or movable die 12, together with additional means for securing the work in position to be operated on. The shaping member or die 11 has a curved surface against y e 1,495,105?v GEORGE E. PAGE, Orr-ROCHESTER), New vonk, AssIGiiTonfTo iuoiirorin'an;nvr-iiiiiivr.y;

As previously mentioned, the invention isV particularly useful in connection with the fabrication of sheet metal vessels having integral tubular'spouts', in accordance with the method disclosedvin my copending application, but the invention is o-f general utility and not limited to any particular use and is also adapted to be embodied in various diiierent forms. Y l

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. A device for curving a tubular spout formed integral with va cup=-shaped sheet metal body, comprising a base, a form for fitting against a supporting inner wall of the cup-shaped body during the curvin op# eration, a die into which the spout is adapted to be pressed, a plunger for bendin the spout, and means for securing the bo y to gf t said base With its inner wail in contact with said form and its spout immediately above said die. i

2. A device for curving a.

fitting against a supporting inner wallof the cup-shaped body during the curvin 0peration, a die vinto which the spout'is a apt= ed to beV pressed, a plunger forn bending the spout, means for securing Athe b'odyto said basecwith its inner Wall in contact with i eration.
