Specification of Letters latent.

Application filed March 11. 1907. Serial No. 361.804.

To all whom 'it may concern:

Be it known that L'THOMAs W. MORRELL, a citizen of the United States, and a resident of the'town of Bloomfield, county of Essex, and State of New, Jersey, have invented certain new and useful Improvements in Games,

- of which the following is a full, clear, and exact description. 0

My invention relates to improvements in metal joints for window glass, particularly to the small panes of irregular outline employed in stained glass Windows to make a composite pane. Y

Heretofore metal strips of ductile, flexible metal in I form have been used to constitute the uniting joint between panes. For this purpose lead cames were commonly used, but the difficulty was encountered that the joint between the metal and glass could not be satisfactorily sealed; there being no close union of parts the panes so fastened were not water proof. To. overcome this a plastic binder was used, but it was found that, when dried these binders failed to adhere to the cames and glass, due to the hard smooth sur- I faces of the metal and glass. A came was next devised having its heart, or that part forming the web uniting the doubly flanged top and bottom, milled, affording increased frictional area for the binder of cement employed; this proved inadequate, due to the limited anchorage afforded the cement and to its effective cohesion being solely directed to the edge of the pane. Thereafter cames were devised having the flanges so formed by the lead-press that their inner faces were grooved with a series of longitudinally extending parallel recesses for the reception of the cement, the heart being similarly grooved with a series of dovetail corrugations. These grooves were formed by the die forming the came and were continuous. Such grooves or recesses have proved to be a source of Weakness, in that as compared with cames of equal weight, the flanges and heart are found to lose the slight stiffness which the non-elastic metal possessed,. and the cames so constructed are readily bent and lose their cement or other binding material, the lead not being inherently strong enough to bear the strain incidental to their purpose. To overcome this objectioncames have been devised with hearts of tinned sheet-iron and others of all hard metal. These forms are expensive and do not readily adapt themselves to art glass work.

The object of my invention is to provide a came of lead having, for given equal weight, first: the strength of a solid came; and second: the increased contact area for cement or other binder of the grooved came. I accomplish these objects by the construction hereinafter described and illustrated in the accompanying drawings in which like reference numerals indicatesimilar parts in the several views.

' Figure 1 is a perspective view of a came embodying my improved features of advantage.-, Fig. 2'is a view in cross-section of same, while Fig. 3 illustrates the inner faces of one pair of flanges, a came being shown in horizontal section. Fig. 4 is a view similar to Fig. 3, but shows the application of the came, fragments of two pane or pieces of glass being shown. Fig. 5 is a view similar to Fig. 2, but also shows the application of the came, two adjoining panes or pieces of glass being shown as jointed by the came.

1 is the heart, core or web which is shown as preferably milled.

2 is the upper double flange and 3 the lower double flange.

4 are cusps or pockets formed in the inner faces of the flanges, both upper and lower. 5, 5 are panes of glass. These cups 4, 4:, are formed after the came is drawn from the die of the lead-press, by indentation, no metal being removed, as in the 'case of the grooved or recessed cames; As this series of indentations does not constitute a continuous absence of metal, the weakness due to such a construction is obviated.

My improved came has all the stiffness of solid metal, while affording repositories for the cement or binding material, and may be formed in the process of manufacture as at present practiced by means similar to that employed in milling the heart, without increasing their cost.

Having thus described my improvement, I claim as my invention:
