NATHAN R. LYMAN, OF CHICAGO, ILLINOIS, ASSIGNOR oroNn-IIALr TO JOSEPH P. ELLAGOTT, or SAME PLACE.

MACHINE FOR MAKING PRINTERS LEADS.

SPECIFICATION forming part of Letters Patent No. 315,0 5, dated April 7, 1885.

Application filed December 18, 1882. (No model.)

To all whom it may concern."

Be it known that I, NATHAN R. LYMAN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Making Printers Leads, which are set forth in the following specification, reference being made to the accompanying drawings, in which- Figure 1 is a front view of a machine embodying my improvements. Fig. 2 shows on an enlarged scale the mold-roller and the roller coacting therewith, the former roller being shown-in edge view as to its right-hand half and in axial section as to its left-hand half, and the latter roller being in similar section and broken away beyond the points of nearest juxtaposition of the two rollers. Fig. 3 shows a plan section of the funnel, taken on the line '00 as, Fig. 1, looking upward and Fig. 4 is a plan section on the line 3 y, Fig. 1, broken away, showing the dovetail slide which holds the funnel against lateral displacement, and at thesame time allows of its vertical adjustment. 1

My invention relates to a machine by means of which lead is formed by the aid of a roller and'a band. I

- The object of my invention is to provide means whereby a continuous strip or ribbon of lead may be made. I

4 In the drawings, which illustrate one way in which my invention may be carried out, A represents. a roller provided with a central groove, a, in the face thereof, between which groove and a band, E, hereinafter described, covering at this point the face of a roller, B, the fused metal is formed into a ribbon. On each side of the central groove, a, a smaller groove, a, is turned, and outside of these grooves a, on the face of the roller A, are turned rabbets a O is a pulley. This pulley has a plain face, except near each edge, where'it has a narrow annular flange, c, which corresponds with the annular rabbet (L The roller B has a plain face, except for the presence of the similar flanges, b, the pulley O and roller 13 being counterparts throughout.- These flanges c and interlock the rollers A and B and keep them in perfect alignment.

D is a funnel, made of wood, cl, inside, and

pulley G and of metal, d, outside, this metal, however, forming the sole material of the extreme tip of the funnel,to insure durability. This funnel slides up and down when occasion requires on a vertical standard, D, being dovetailed thereto, as

shown in Fig. 4., for thepurpose of permitting vertical adjustment without lateral displacement. The object of thus adapting the funnel to be vertically adj ustable is to admit of the sub stitution for the roller A of another roller havingagroove, a, of difl'erent depth, thus providing for the making of leads of different thicknesses.- The metal, (1, formingthe outside of the funnel is provided with flanges d which fit into the grooves a, and thus secure a more perfect relative alignment of the funnel D and the mold roller A than would be attainable simply by the use of the dovetail slide shown in Fig. 4, the object of this nice adjustment being to deliver the' molten metal from the funnel directly and wholly into the groove a, and not to either side thereof, where it would I b, in conjunction with the rabbets a, serveto not only be itself wasted, but would also clogv the machine.

A steel band, E, passing around the roller B and pulley O and wholly under the roller A, serves to transmit power from the pulley G to the roller B, and said pulley 0 may be revolved by any suitable appliance or power. But this band E is more especially intended for the purpose of confining the fused metal in the groove on after it has been rolled between'the rollers A and B until such metal shall have cooled, the combination of the band be supported in part, as shown, by the stand- 1rd D through the funnel D. Motion is com municated to the machine by any suitable 1 driving mechanism connected withthe shaft of the pulley O. The outer face of the band E and the bottom of the groove'a. are covered with cloth, paper, or other nonconducting material, a, to prevent the too rapid chilling of the fused metal, such as would result fromimmediate contact with the metallic surfaces of theroller A and band E. The obj eet of malting the inside of the funnel of wood is also to prevent chilling of the lead prematurely.

The operation of the above-described embodimentof myinvention may be summarized asfollows: Fused lead alloy-such as is in common use for making printers leads-runs in a continuous stream from the furnace-into the'funnel; thence between the rollerA and band-covered roller B and wholly within the groove a,which groove regulates atthispoi n-tthe thickness as well as width of the ribbon in process of formation, thence under the roller A to the points of the roller A and pulley O which are in nearest juxtaposition, duringwhich period the band E retains the gradually cooling metal in the shapeit acquired' by its passage between the rollers A and Bat their points of nearest juxtaposition; thence the lead, which by this time has solidified, is discharged from the machine in a continuous ribbon. Throughout itswhole passage-from its entrance into the funnel to its discharge from the machine-the-lead isprotected fromtoo rapid chilling by the non conducting properties of the surfaces with which it comes in contact.
