UNITED STATES PATENT OFFIon.

WASHINGTON FOGLESONG, OF DAYTON, OHIO, ASSIGNOR TO THE DRIPPING PAN COMPANY, OF SAME PLACE.

IMPROVEMEN T IN WlRE-BENDING MACHINES.

Specification forming part of Letters Patent No. 185,514, dated December 19, 1876 application filed July 24, 1876.

Be it known that I, WASHINGTON FOGLE- SONG, of Dayton, Montgomery county, State of Ohio, have invented an Improvement in Machines for Bending Wire, of which the following is a specification:

My invention has for its object, principally, the bendingof wire into regular shapes, rapidly and conveniently, for the wiring of sheetmetal pans; and it consists, in the first part, in the combination of a rotating spindle, carrying the form, with a pressure-arm to press the Wire to the form as the latter revolves. Myinvention consists, in the second part, in connection with the rotating form, of a series of guides, set spirally upon the form, to give the proper guidance to the wire in the formation of the first turn. My invention consists, in the third part, in a certain combination of devices, by which the form may be increased "or diminished in size, to make wires for different sizesof pans.

Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is aperspective view of the pressure-lever. Fig. 3 is a perspective view of the form.

A is the main frame of the machine, having ordinary beariligs, in which the shaft B is journaled, which may be driven by gearing or pulley, or, for small wire, turned by a crank. To the shaft B a head, 0, is firmly secured, to which two heads, D D, are fitted to slide, the latter being adjusted to and from each other by separate screws 01 d.

Upon each of the sliding heads D D two other slides, E E F F, are fitted to move, being adjusted to and from each other by separate screws 6 e ff.

To the four slides E E F F four posts, G, are firmly secured, and the outer surfaces of these posts constitute the form proper, upon which the wire isshaped, and they gepresent exteriorly the configuration of the pan or other article for which the bent wire is intended. Being attached to the slides E E F F, the posts are expansible, sothat the form may be increased or diminished from one size square to another, or changed from a square to a rectangle.

By the use of a different number of posts the wire may be bent in triangular form, and by the use of non-expansible forms ellipses and like figures may be formed, the important active agent, in connection with the revolving form, being the reciprocating pressure-bar H, whose motion, following as it does the configuration of the form, causes, by its pressure, the wire H to hug the form and adopt its shape.

It is proposed to wrap the wire in spiral shape, and to make as many wrappings as the posts G will contain, so that wires sufiicient for quite a number of pans or vessels may be made at a single operation of the machine, the coil of wire, after being bent, being cut at one of the corners or sides.

To support the posts rigidly, I introduce gage-plates I, one or more, and these may be marked for standard-size pans, so that they may be used to set the posts up to, in efiecting' their proper adjustment.

To guide the wire in eii'ecting the first turn, I fix guiding-steps K to the bases of the posts, which serve to push out the wire and lever H to the extent of one-fourth the thickness of the wire at each corner, and thus enable the wire to lap and pass the first end of the wire after making one turn, the first end being bent down and inserted in aperture g before the bending commenced.

The wire in the process of bending lies in in the rabbet h of the bar H, and as the bending proceeds the wire in being wrapped spirally gradually pushes out the lever laterally, the latter being fitted to swing loosely and move sidewise on the shaft or rod L.

Guides M M are attached to the under side of the lever H, one of which, M, provides for vertical play, and the other confines it strictly to the path of the rabbet in every direction. The pressure of the lever may be regulated by the weight of the lever itself, or the addition of a weight, N, or by any other well-known expedient adapted to this end. The wire, before passing to the bending appliances, may be straightened continuously by the hollow rotary straightening-mandrel I, used commonly for this purpose.

I claim- 1. In a machine for bending wire, the combination of a rotary form or pattern, and areciprocating pressure-bar acting upon the wire pattern by pressing it directly against the same, substantially as described.

2. In combination with the form G, the

series of ledges or guiding-steps K, substantially as and for the purpose specified.

3. In combination with the form-posts G, the sliding adjustable plates E E F F, and

sliding adjustableheads b a set my hand. WAS summon noennson'e.
