APPARATUS FORMAKING PLUMBERS TRAPS. No. 327,292. Patented Sept. 29, 1885.

PATENT OEEIcEo JOHN MCCLOSKEY, OF NEW YORK, N. Y.

APPARATUS FOR MAKING PLUMBERS TRAPS.

SPECIFICATION forming part of Letters Patent No. 327,292, dated September 29, 1885. Application filed December 16, 1879.

To all whom, it may concern.-

Beit known that I, JOHN McCLosKEY, of the city, county, and State of New York, have invented certain Improvements in Means for Manufacturing Plumbers Traps, of which the following is a specification.

This invention relates to that class of an apparatus designed for the manufacture of traps of soft metal; and its object is to provide for the bending of the traps in the requisite shape by power applied externally to the die to give a curved form to the issuing material.

A suitable cylinder or reservoir for lead or soft metal is constructed with an annular die, through which the. metal may be forced in tubular shape, and is provided with a ram or plunger actuated by hydraulic or other suitable power to force the soft metal through the annular die in the tubular form aforesaid. Loosely attached to the core, which forms the central portion of the die, is a bulb spherical, spheroidal, or of other appropriate contour, the ofce of which bulb is to support the inner walls of the tube in such amanner as to prevent buckling or wrinkling of the metal when the tube is bent as the latter issues from the die. Fitted externally upon and around the die is an annular collar, upon which is provided a curved shoulder, over which the pipe is designed to be bent, and also provided with a lever constructed with a gripping or bending device in such a manner that by operating the said gripping or bending device the pipe may be grasped between the latter and the shoulder and turned over in one direction to form one of the bends of the trap, which done, the pipe is released'from the gripping device, the collar is turned axially onehalfl of a revolution, thereby bringing the curved shoulder together with the lever and gripping or bending device at the opposite side of the pipe, in order to repeat the bending operation upon the next adjacent portion of the pipe, and in an opposite direction in order to give the second bend requisite to the formation of the trap, which latter is severed from the issuing pipe by the use of a saw or other suitable means preparatory to the formation of another trap in the same manner.

Figure l is a plan view representing the machine embraced in my said invention. Figs. 2 and 3 are side views, and Fig. 4 is vertical longitudinal section of said machine.

A represents the chamber containing the lead or other soft metal of which the traps are to be made, and which may be heated by any suitable means to the temperature which may best facilitate the ilow of the lead in a solid, semi-solid, or plastic state. In the upper part of this chamber is provided the annular die a, of which the core is shown at b, the said core being held or steadied in position by any suitable means*as, for example, radial supports, as indicated at a in Fig. 4.

At the lower or opposite end of the chamber A is provided a plunger, B, actuated by hydraulic or other suitable means to force the lead or soft metal contained in-the chamber A outward through the annular die a.

C is a bulb or ball of solid metal of spherical, spheroidal, or othersuitable form, and connected by a shank, a2, and pin c with the core b, as shown in Fig. 4. Other methods of connecting the bulb with the core may be adopted, if desired.

D is an annular collar fitted around the upper end of the annular die in such a manner as-to freely rotate around said die, and yet be incapable of being lifted therefrom.

The manner of attaching the collarin place as well as the construction in detail of the die being matters of judgment merely, and within the known scope of the arts, need no special description here. Upon one side of the collar is formed a curved shoulder, A', the curvature of said shoulder radially from the axis of the collar corresponding to the curves of the inner sides of the trap to be made, as more fullyindicated in Figs. 3 and 4.

Pivoted to the collar D, with its axis of motion coincident with the axis of the curve of the shoulder aforesaid, is a lever, E. On this lever is placed a sliding gripping-jaw, B, actuatedby an elbow-lever, C, pivoted to the lever E, as shown at fin Fig. l.

It is to be remarked that the shoulder A, While having the radial curvature hereinbefore described, is made concave transversely, as more fully shown in Fig. l, this transverse contour being semicircular to correspond with one-half of the circumference ofthe pipe formed from the metal issuing through the die a. rIhe outermost end of the gripping-jaw B is made concave in like manner, as also represented in Fig. l.

In the operation of the machine, the lever E l is broughtto a horizontal position, as represented in Figs. l and 2. The plunger Bbeing set in motion the metal is forced from the chamber A through the die a in tubular form. The elbow-lever C is then brought toward the lever E 'to cause theissuing pipe to be gripped with more or less snugness between the gripping-jaw B and the shoulder A, whereupon the lever is turned over the shoulder with a rapidity of movement proportioned to the rapidity with which the metal issues through or from the die, thereby causing the material, as it issues in tubular form from the die, to be curved around the shoulder aforesaid, thus forming one of the bends of the trap, as indicated in Fig. 4. When this is done, the elbow-lever is manipulated to relieve the pipe from the grip of the jaw B. The lever E is reversed to bring the gripping-jaw B clear of the pipe or tubular material. The continued issue in an upward direction of the material carries the `just-formed bend clear of theshoulder A and ,the lever E, together with the gripping-janT B, and the collar D with its shoulder A is turned axially around one-half of a revolution to bring the said parts to the opposite side of the tube issuing from the die, and the operation aforesaid is repeated, the result being to give asecond turn to the tube, but in a direction opposite to the first, so as to form the second bend of the trap, as represented in Fig. 3. This done,and asufticient portion of the metal having been allowed to issue in an upward direction and in a straight formirom the die, the second arm of the trap is thus formed on the latter and the trap is sawed off.

The operations are repeated in succession for any desired number of traps, it being understood that the bulb C being Within the pip e as it is bent, as hneinbefore explained, prevents the crushing in of the walls of the pipe 0r their buckling or Wrinkling, which would otherwise be likely to occur from the stress on the tubular material.

If for any reason it is desired that the bends be in planes at an angle to each other, instead of directly opposite each other, as described, the lever E and collar D are turned the proper proportion of a revolution, and the apparatus is manipulated in the same manner as when the bends are formed directly opposite each other.

It is of course to be understood that in making traps With one bend only the shoulder A can be stationary in its relation With the die, and that the lever carrying the gripping or bending device may in such case be incapable of axial movement around the die, it being only necessary that said lever with its gripping or bending device should be in proper relation with the shoulder of the die and the bulb.

It is furthermoreto be remarked that, in

case the apparatus is to be constructed for use in making traps in which the bends are in planes at an angle to each other, the bulb may be connected with the core by a universal joint.

Vhat I claim as my invention isl. The combination of an annulardie for soft metal, a bulb connected to the core thereof, a jaw or shoulder adjacent to said die provided With a rounded arc-shaped face, and a bending-lever provided with a jaw having a rounded arc-shaped face, substantially as described.
