CORNlCE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 784,725, dated March 14, 1905.

I Application filed October '7, 1904. Serial No'. 227,587.

IT 0 all whom it may concern.-

Be it known that 1, JOHN W. YATES, acitizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Cornice- Making Machine, of which the following is a specification.

This invention relates to cornice-making machines.

The object of the invention is to provide a machine which may be operated for forming coves, curves, or bends to metal with rapidity and certainty, which shall be exceedingly simple of construction, and which shall be adjustable for accomplishing all kinds of cornice work.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a cornice-making machine, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in perspective of the machine, a portion of one end being broken away. Fig. 2 is a view in end elevation exhibiting the machine. Fig. 3 is a perspective detail view of a portion of the plunger. Fig. 4 is a perspective detail view of a portion of one of the formers. Fig. 5 is a similar view of a modified form of former.

Referring to the drawings, 1 designates the stock of the apparatus, 2 the plunger, and 3 the former. The stock comprises two die members, one of which is stationary and the other adjustable. The stationary die member embodies a relatively broad base 4, provided with a plurality of transverse slots 5, and a jaw 6, disposed at right angles to the base and having its upper edges beveled outward and downward. The adjustable die member emforming a true curve in the metal.

bodies a relatively narrow base 7 to rest upon the base 4 and provided with a plurality of orifices 8 to register with the slots 5, and a jaw 9, disposed at right angles to the base and having its upper edge beveled outward and downward, the sharpened or reduced edges of the two jaws being provided to enable the operator to accomplish accurate profile work. The slots and orifices are engaged by bolts 10, the upper ends of which carry thumb or machine nuts 11, by which the bases may be clamped together, thus to hold the two jaws at any desired adjustment.

The plunger 2 is provided at its upper end with laterally-projecting battens 12, which furnish means for holding the plunger in operative position on the machine that carries it, the latter not being shown, as it forms no part of the present invention and may be an ordinary stamping-machine or the like. Upon the lower end of the plunger is detachably disposed the former 3, which may be a split circular tube, as shown in Figs. 1, 2, and 4, or a split circular tube 13, having a wooden filler 14, as shown in Fig. 5, or it may be of any other desired shape the contour of the operative face of which will be governed by the character of work to be done. It is to be understood, of course, that there will be a plurality of these formers with each machine and that they may readily be removed when desired from the plunger, the frictional contact between the opposite walls of the slit operating to hold them in position thereon. As will be seen by reference to Figs. 1, 2, and 3, the lower edge of the plunger is rounded, and this edge will constitute one former for making the smallest curves or coves, and to increase the size of the curves or coves it will only be necessary to supply a former of the desired size. In the formation of a curve the sheet of metal is placed upon the upper edges of the jaws and the plunger is depressed, thereby forcing the metal down between the jaws and By turning the sheet of metal over a curve the reverse of that made can be secured, and so on.

In making cornice-work where there are to be square and curve bends the square bends will be made on a separate machine first and thereafter the round bends or coves will be formed, thereby causing the square bends to retain their given contour.

Having thus described the invention, what is claimed is- 1. An apparatus of the class described comprising a stationary die member embodyinga base provided with a plurality of transverse slots and a jaw disposed at right angles to the base and having its upper edge beveled outward and downward, an adjustable die member embodying a base to rest upon that of the stationary die member and provided with a plurality of orifices to register with the slots and a jaw disposed at right angles to its base and having its upper edge beveled outward and downward, bolts passing through the slots and orifices, and nuts engaging the bolts to hold the jaws at any desired adjustment relatively to each other.

2. In an apparatus of the class described, the combination with a plunger having a split tube detachably connected therewith to cou stitute a former, of a stock comprising a stationary die member embodying a base provided with a plurality of transverse slots and a jaw disposed at right angles to the base and having its upper edge beveled outward and downward, an adjustable die member em JOHN W. YATES.
