METHOD OF MAKING LEAD GAMES.

This invention relates tothe method of decorating and finishing lead cames wherein it is desired toprovide a lead came of an artistic design. v I

The method includes the applying of forming different decorative surfaces on the cames in a. simple and effective manner by changing the master patterns.

A further object of the invention resides in finishing and forming cames in a manner so as to draw out the came body and at the same time impress into the surface thereof such decorative designs as to provide a very attractive and desirable came which is used for leaded glass windowsand the like. My

invent-ion is designed to carry out the meth-' od in an economical, simple and practical manner, permitting the formation of the cames with such a decorative facing over the entire outer surface of the same as may be desired. The lead cames are of a soft nature and are readily receptive to impressingdesigns into the surface of the same, and my method is carried out in making the cames in a manner so as to facilitate the accomplishing of the method without extra operation and expense. V

' These features, together with other objects and details of the carrying out of the method will be more fully and clearly set forth in the specification and claims. To facilitate the clear understanding of the carrying out of my method I have chosen to illustrate in the drawings a simple machine designed to make the cames.

Figure machine.

Figure 2 is a plan view of the same. I Figure 3 is a side elevation of the same. Figure 4 is a diagrammatic s1de view. Figure 5 illustrates a portion of the came before it has been finished by my method. Figure 6 illustrates a portion of the came as it would appear when finished by my method.

In carrying out my method the lead came such as A illustrated in Figure 5 is in its ordinary drawn state as it appears after it comes from the extrusion machine, and the came A illustrated in Figure 5 is designed with a center steel reinforcing member 10 which is placed into the opening designed to receive the flat bar-like steel member. This opening is formed in the came as the same comes through the extrusion machine and the steel band is inserted within the 1 illustrates a front view of this 7 is made of soft or comparatively soft 14 and 15 are supported in the side 16 of the forming machine B.

The machine B is erating pulley 17 which is adapted to drive the shaft 18, which in turn drives the gear 19, positioned on one side of the machine B. The gear 19 meshes with the gear 20 which operates the shaft 21 and drives the gear 22 on the opposite side of the machine to the gears 19 and 20., The gear 22 meshes with the gear 23,' While the gear 23 is in mesh with the gear 24. The. gears 23 and 24 are secured to and adapted to operate the shafts 14 and 15, respectively.

The forming wheels 12 and 13 are removably 'or replacably held on the shafts 14 in an ordinary well known manner, the detail of which is not illustrated in the drawings, so that different forming wheels may be employed in the carrying out of my method. Each of the wheels 12 and 13 are formed wlth an inner surface 25 which is of a design, decorationv or shape so as to provide the desired shape and design to the outer surface of the came A adapted to be passed through the'machine B.

The machine B is provided with a pair of guide wheels 26 which are supported by the bifurcated brackets 27 ina manner so as to hold the 'wheels diametrically opposite eachother and to cause the surface of the wheels 26 to engage the shank 28 of the came A together and at the same time firmly grip the came on the shank while the came is passing through the machine B. The width of the guide wheels 26 is such as to freely fit the glass recesses or channels 29 formed in the side of'the came A, as illustrated in the diagrammatic illustration in Figure 4,

and as would be apparent from the front view in Figure 1. In fact, the guide wheels fit the recesses or channels 29 closely so that as the came A passes through the forming rollers 12 and 13 the material of the came is squeezed closely against the wheels 26 in a manner to squeeze the shank provided with an op- .and the serrated surface of the wheels 26 is caused to bite into the shank 28 to prov1de a serrated inner surface" 30 to the shank 28 and at the same time squeezing the body of the came A firmly-against the steel rib 10 from all sides to form the came of the desired cross sectional shape vand to' impress into the surface thereof the decorative finish such as 32, illustrated in Figure 6. This decorative surface may be of the same design and nature as the decorative surfaces on the Wheels 12 and 13, and thus I provide a method of making cames for leaded gl-ass windowsof a most desirablenature, having a design adapted to be attractive and at the same, time facilitate the better making of'the came itself.

Theplain' unfinished design of the came is illustrated in Figure Whll the'finished drawn out came wllidllahfls been reworked with the desired outerfdesi'gn orl'finish is clearly illustrated inFigurc 6., By changing the wheels 12 and 13'tosubstitutesvheels with adiiferent surface design, I can'make many differentdesiigns by passing the same througlrthe forming machine BI Thus in "carrying out my method therough unfinished came which comes from the extrusionma'chine' is adapted to be passed'through the forming machine B wherein theidesired design or configuration is pressed and formed into'the came body; stretching the .came out as it passes through this forming process and at the same time providing a finished" came-much to be preferred over the ordinarilyextrudedcame.

My 'method consists in' placing the ex truded, came in positionffto be engaged on practically all sides thereof'and then draivii ng the same out to fern/ 11a finished came with a decorative or configured outer face and providinga finished came-to the'desi'red' 'slze and nature with an outer decorative facef The method is simple yet'v'ery effec- I claim:

tive'i'n providing a finished-came with practic'ally little 'or no extra costsin the formation of the same as it is necessary to form the :came about the. reinforcing rib 10 in this construction and even Without the rib lOriti is necessary that the came be formed of the desired size and shape so that in passing there-me into the decorative forming rollers 12 and 13 I provide a method of making and forming the same which 'isvery desirable." My method has been successfully carried out in making cames with a hammered desi 'n, a rough cast design havmg a very roughened outer surface, a

frosted design and many 4 other attractive designs to the outer surface and formation ofthec'ame.

In accordance Withthe patent statutes I have described the principles of operation of my'method'a'nd While I have illustrated means of carrying out the method, I desire to have it understood that this is'only suggestive and thatthe method can be carried I stantially their'central portionsby' a Web c'ompris'ingpassing the came through rotary 'die means acting'upon the outer surfaces of said flangesto ornament thesame and at the sametime passing the web. of the came through rotaryf means' disposed at right angles to said die means to serrate both surfaces of said-web and force theiinaterial of said Web about a reinforcing means therein.
