Different-sets of discs with" irregular edges .may be readily :implaeed, that is, assembled iinto ithe machine, in order to secure a; greater degree of-irregularity,:0r for diiferent'sizes of original came section. These irregular .edged' discs are driven by having their-shafts connectedby inter-e115 gaging gears, so that driving one ofthe shafts turns both.

Such ditferentiahgear drive usually requires only ,a slight ariation in size,-s0 that'the creepingot'one-set of irregular discs with respect to the i other is very slight, and in no sense to a degreevvhichnxvould tear the-metal in the leaves.

The lead in such canoes is veryductibleand liable to [m-is formation in the handling, so that diliiculties arise in-making specially formed leavesas to surfaces or edges that wvill'lstill meet the requirements for artistic purposes, and gvvill 'lUBJII'QgUlEllllLFQS will thus-be impressed upon" likewise provide a came meeting the structural requirements for use and ready assembling. This invention aims to provide such machine in simple form, adapted to the re quired variations for production, and for high speed of operation, as well as a machine that may be used in any shop to provide small quantities of cames having the particular characteristics of finish for a particular window, or for each particular set of windows that go into one structure.

While particularly adapted to special effect of leaves on cames, in various forms the simple mills may be used to reduce came blanks either cast or so-called hydraulic extruded blanks,into the precise size and any shape desired by the glazer. noted that the multiple part rolls provide for the lateral contact with the leaves to draw the came through the mill, and that the central. heart-engaging member may be a die or inside mandrel, or on a roller, or

may be a stationary circular part of the mill,

tion, thus providing an eflicient mill or machine for making cames in shops as desired, from the blanks of larger sizes or straight conformation.

Various arrangements of mills may be used, with some of the parts herein shown and described, or other modifications without using the particular entire combination, and for producing a great variety of finished product, without confining this invention to the specific embodiments herein described.

Particular forms of these machines will now be described with reference to the drawings showing particular embodiments, in which:

Fig. I is a side elevation of a preferred form of the machine.

F ig. II is an elevation viewed on the axis of movement of the came being rolled.

Fig. III is a cross-section on enlarged scale, of the rolls with came. fragmentary, on the section III-III of Fig. I.

Fig. IV is an elevation showing the irregular rolling discs and principal adjacent parts in operative relation to a came being rolled.

Fig. V is a fragmentary view of a modified form of machine showing the rolls and other parts engaging and fashioning the came.

Fig. VI is a fragmentary cross-section on line VI-VI of Fi V.

Fig. VII is a cross-section of a came blank It will be as in a cast came, with dotted lines indicating sectional reduction when manipulated by my machine.

The machine in Figs. I to IV comprises a base 1, a frame or hearing support 2, with shafts 3 and-l supported in the frame or in bearings carried thereby. Gears 5 and 6 are keyed to the shafts and engage each other so that turning one shaft by crank 7, turns the other shaft in the oppositedirection, and in the form shown, at the same speed.

' On the other side of the frame 2 the projecting shaft ends support a number of cooperating rolls, which at their adjacent peripheries form a clearance in H sectionof the desired size and configuration, to provide for the rolling of the came for the finishing characteristics desired. These came rollers comprise the inner d1sc 8 reglstering 1n the plane of the inner disc but one larger than the other so as to form a side resisting plate for the passage of the came leaf 011 one side.

outer margin forming a tight abutment to resist the bulging of the surface of the leaf of the came. All of these rolls are securely locked together by nuts 15 threaded on the free ends of the shafts 3 and 41-. A guide 16 rigidly secured to the machine frame 2,

The next member of the rolls is an irregular disc 10 and irregular disc 1O set flat against 8 and 9, respectively, and

has a toe 1G projecting close to the periph- I cry of the heart roll on one side, with a guiding surface 16* adapted to contact with one side of the heart and cooperate with the rolling contact of the heart rolls, for the purpose of straightening the heart as it emerges from the rolls and prevent its curling. Extra plates 17'1T and 18--i8 may be used to provide registering interengaging edges of the outside confining rolls, or the edges of the outside confining rolls may he stepped in order that a resistance against lateral pressure be provided for the rolls 8 and 13, at the point where the pressure on the came tending to compress it requires lateral resistance to prevent distortion of the leaves Where not desired;

The discs with irregular peripheries are in pairs 12 and 10 and 12 and 10*". By having the pair on one shaft uniform as to the irregular periphery, the resultant edges of theleaves which they engage, will substan-. tially register on the finished came on. one

though irregular from the outside or inside of tl1eglass, without seeing any overlapping of the opposite leaf, or the cement used to secure the glass, therein. These irregular disc rollsofthe lea-f edges are preferably 'held by a'lzey 19 in each shaft, but enga e in one of a number of keyways or notches, which in the figures are rihered f n i to lVith a-nuinber of setting positions, resulting from having the key engage one or the other notch, the pair of top disc rolls will have different irregularities opposed to the pair ofbottom disc roll. by simply changing the registering of the discs on the shaft, WllEll'bllflQQillS 5 and 6 are kept in mesh in Variations of the relations .of'the disc rolls may also be accomplished by-withdrawing one of the ears 5 7 F): ergo and-shilling it a ten: r eth. mum wil advance the upper or iower' disc rolls with re juxtaposition of the irregularities.

In the modification shown in i* it and V1,;prov1sron 18 made for hand a canie blank, such as shown in F vii as, for

instance, the cast blanks, or drawn blanks thicker than-is required for the ti 'islied section of heart and leaves, in producing the product of my machine. For this purpose the came in section A is reduced to the ilighter section and irregular finish i, with theithicli heart B reduced to B. and the general section thick leaves U reduced to the lighter-section Ci, shown dotted in Fig. Vii. Starting with such a thicker came, the rolls 2l21 having toothed or roughened faces 4L. so-that siinultaneousl with the squeezing the material or they of the came leaves, leaves spread as to en go the periphery of the irregular disc rolls, and the irregularities of the leaf edges are thereby impressed and at the same time the irregular disc rolls cooperate to pull the leaves and thereby the came through the machine;

will-thus be seeirthat these machines or inills serve to provide a simple device for. manipulating cames, particularly such acct to the heart as lead or other soft metahfor the purpose of. producing anyirregula-r and constantly ying relation of leaf inargins, and vari- ZtLlUIiS of the leaf surface as well. machines are simple. and may preferably be hand operated as by the :crank indicated, but for large production :may be power driven. In this art the production of special can'ie ,elfects and linishusually involves the treatn-ientof lengths of blanks and of a different finish or character for different jobs, such as set of Windows or the particular glazing for one "window, and these mills supply in particular a compact, convenient and durable machinefor the glazers shop use. A series of sets of irregular discs, as for the machines shown in Figs. I and IV, may be kept in stock in sets of twopairs each, and of different sizes to manipulate different sizes of cames. The irregularities of the finish on the leaf edges may be varied by different. setting of the disc rolls on the shafts, and the assembly nd arrangement of the machine are such as to readily permit the shifting of discs for Should it be desired to prod ce a-constantly varying irregularity over a long strip of came, the two-gears 5 andfi may be made of slightly different size, as, for erranngleone having one or a few teeth more than the other, the result of which will be to drive one shaft 3 differentially faster or slower than theother'shaft' l, and as each of irregular disc rollsis keyed to its These respective shaft, one of the pairs will creep 1 slightly ahead of the other at each revolution, and for a large number of revolutions the same irregularities on one pair will never againregistcr with the irregularities on the other pair of disc rolls. In thenor- Such dilferentialdriving will tend also to cause the leaves on one side to creep a little beyond those on the opposite side of the heart, which, however, will be absorbed by the d *ctility of the material, and simply s rves to increase the desired irregularities for both leaf edges and outer surfaces.

The manipulation of these mills or machines will be readily understood from the aioregoing description, which consists in feeding a plain came blank into one side of the rolls or mill, and by turning the crank the rolls bite the end and draw the heart and leaves through the cross-sectional space provided, while'during its passage the engagement with the irregular disc rolls provides the irregularities and the other portions of the mill suitably support the ductile material in its passage, resulting in the delivery at the other side of the mill in the finished product with the much desired characteristics.

While various modifications may be made from the particular firm of the embodiments of my invention herein shown and described, without departing from my invention,what 1 claim and desire to secure by Letters Patent is:

1. A mill for rolling glazing bars or cames, comprising multiple rolls having roll sections engaging the edges of the came leaves with irregular peripheries.
