ROBERT MARGHER, OF NEWT YORK, N. Y.

ENAMELING PICTURE-FRAMES, 85C.

Specification of Letters Patent No. 29,609, dated August 14, 1860.

T o all whom it may concern:

Be it known that I, ROBERT MARCHER, of the city, county, and State of New York, have invented certain new and useful Improvements in Machinery for Enameling Picture, Looking-Glass, and other Frames; and I do hereby declare that the following is a full, clear, and exact description there-A of, reference being had to the accompanying drawings, making part of this specification, in which- Figure l, is a plan of the machine; Fig. 2, a front elevation; and Fig. 3, a vertical section thereof taken at the line A, a, of Fig. l.

The same letters indicate like parts in all the gures.

My said invention relates to improvements in machinery for enameling oval and other curvilinear formed frames. And in my said invention the frame to be enameled, whether oval or of other curvilinear form, is secured to4 a face plate which also carries one or more patterns of the ,general form of the frame, and of the ornaments desired to be produced by the enameling. And with these are combined one or more tools each, if more than one be used, free to receive independent movements from a separate pattern.

In the accompanying drawings (a) repre sents a suitable framein which is mounted a vertical shaft (b) to be rotated by any suitable means, whether by power or by hand. The upper end of the said shaft carries a face plate or wheel (c) to the upper surface of which the frame (d) to be enameled is to be secured by any suitable means. The periphery of this face plate (c) is to be fluted and smooth in alternate sections, or all iuted, or all smooth, and of the general form corresponding to that of the general form of the frame to be enameled. The regularity, or irregularity of the periphery is to depend upon the kind of ornament desired to be produced on the surface of the frame. On the upper surface of the said face plate, and a little within its periphery there is a raised flanch (c) of the same curvilinear form as the periphery of the face plate, and with the outer edge thereof formed either in sections alternately fluted and smooth, or all fluted, or otherwise formed to correspond with the design desired to be produced on the upper portions of the face of the frame.

The frame to be enameled is to be coated with composition in the usual manner, and

therefore not necessary to be described, and this composition is to be formed and worked down by a tool or former which I make in two parts (e) and f) the lower edge of the one (c) being formed the reverse of the outer and inner surface of the moldings of the frame, as at (g) and (it) and the lower edge of the other (f) has its lower edge of a form the reverse of what may be termed the summit molding of the frame. The tool (e) is attached to a bar and the other tool (f) is in like manner attached to another bar similar to the bar At one end both of these bars are connected to the standard (la) of the main frame (a) by a fulcrum pin (l) which passes through an elongated slot made in each of them so that the said bars can turn on this pin as a fulcrum and slide on it longitudinally; and both ends of the said bars are fitted to slots in the two standards (7s, c) so that they can slide therein freely but accurately.

The bar (j) is provided with what may be termed a tracer (ml) which embraces the sides, and rides on the upper surface of the flanch (c) so as to follow the form of the periphery and of the upper surface of this flanch as the face plate rotates with the frame (CZ) and thereby impart motion to the tool (f) which will make the edge of the Said tool (f) work down the composition on the frame (d) to a form corresponding with the form of the said flanch whatever that may be. Instead of making the tracer to embrace the said flanch it may be made to bear against the outer or the inner periphery only, and be held thereto by the tension of a spring, or the equivalent thereof. And if the weight of the bar (j) be not sufficient to hold the tool down to the upper surface of the 'lanch additional weight or a spring may be added. The bar (z') is also provided with a tracer (n) so formed as to bear against the periphery of the face plate by the tension of a spring (o), or equivalent means, applied to the bar, and on the upper surface of the flanch (0'), if desired, as it is sometimes desirable to give`to the part of the frame (d) acted upon by the tool (c) a waved or other ligure requiring an up and down movement.

For more complicated ornaments the tool, for working down the composition, may be divided into a greater number of parts than two, each separate part being attached to a separate bar, or equivalent, and operated by a separate fianch on the face plate, or some equivalent device. But for frames with less ornaments such, for instance, as frames with smooth moldings, or where the moldings are required to be waved all alike, a single tool operated by a single bar, or equivalent means, will be sufficient.

Letters Patent were granted to me bearing date the 7th day of September', 1858, for a machine for enameling oval frames by means of a tool cont-rolled in its movements by what is known as the trammel, but that is necessarily limited to oval frames, and can only be operated with one tool at a time, and is not adapted to ornaments such as can be given by my present invention. And I am also aware that Letters Patent were granted to Vm. Gardner on the 7 th day of August, 1858, for a machine for enameling oval frames by causing the frame to travel in an oval path the tool being attached to an arm which is free to vibrate toward or from the axis of rotation of the molding so as to be self adapting in such direction to the form of the molding, but that it is defective for the reason that the tool which is to work down the composition musfl receive its m0- tion from the frame with the composition on it, and in consequence such composition is laid unevenly on the frame. I do not therefore wish to be understood as claiming broadly the method of enameling frames by a tool in combination with mechanism for moving the tool so that it shall conform to the general ligure of the molding. And although I prefer the mode of application above described, I do not wish to be understood as limiting my claim of invention to such mode of application as my said invention is susceptible of a great variety in the mode of construction, as for instance the tools may be mounted so as to travel around over the frame, instead of turning the frame under the tool. And again instead of controlling the tool by a pattern to determine the general configuration of the frame as above described this may be done by any of the known, or other, means, and still retain the pattern or series of patterns to control the tool or tools for determining the configuration of the ornaments, such as waving the surface. And therefore I do not limit my claim to combinations in which the pattern, as one of the elements must perform the function ofr controlling the tool or tools to give the entire form, as the principle of my invention will be developed if the pattern or patterns perform, in such combinations, the function of controlling the tool or tools to determine any portion of the configuration; but

IV hat I do claim as my invention, and desire to secure by Letters Patent, is-

l. The combination of a movable too mounted substantially as herein described, for laying enamel or composition on curvilinear frames, with a face plate carrying the frame to be enameled and a pattern of the form required to move the tool, substantially as, and for the purpose, specified.

2. The combination of two or more movable tools, mounted substantially as herein described, so that each shall be capable of independent motions, with a face plate carrying the frame to be enameled, and two or more patterns, one for imparting the required motion to each tool, substantially as, and for the purpose, specified.
