GLASS-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N O. 706,550, datdAugust 12, 1902.

Application filed September 16, 1901. Serial No. 75,563. (No model.)

.To all whom, t weary concern.:

E@ it known than, HENRY` contines, a @itii zen of the United States, residing at Oak Sta- My invention is an improvement in glass:

making machines, and relates particularly to that class forrolling the molten mass of material into flat plates of glass of any desired widths. p

The object'ofmy invention is to provide a machine by which the glassisfiattened out by a series of rollerswhich are tempered and regulated to suit the condition and state of the molten glass; and another object is to provide the roller with a suitable covering that shall prevent to the smallest degree the roughness or defects of the` glass so com mon to machines now generally used.

A further object of my invention is to provide an arrangement of pipe for feeding steam or hot or cold water to the cylinder forregulatin g the temperature thereof; and with these objects in'vie'w myf invention consistsin the peculiar construction and novel combination and arrangement of` parts, aswill be fully de-f scribed in the following specification, reference being hadto the drawings, in which- Figure l is a side elevation of myimprovement, one set of gearwheels-being removed and shown in dotted outlines for the purpose of showing the bearing-boxes. Fig. 2 is an end View of the machine. Fig. 3 is avertical central section. Y taken through one pairof cylinders. Fig.` 5 is a detail section taken about on Vthe line 5 5 of Fig. 4. i

In constructing a machine .in accordance with my invention I employ a frame A, con-l sisting of two side plates A A, suitably mounted upon sills A? A2 and held together by stay-bolts A3 A3, cach plate having its opposite vertical edges provided with. a series of raceways or slots a ct a, in which are slidably held journal-boxes B, having shafts B held therein, upon each of which is mounted a hollow cylinder C. These cylinders form an import-ant feature of my invention, each consisting of an outer shell C', having flanges C2 C2 arranged at the ends thereof, and with shown.

Fig. 4. isa horizontal section .inders are closed andmade `steam or water tight by means of end plates C5 C5, and as the cylinders are made in pairs-thatis, two cylinders being arranged` upon the same horizontal planethe plates of one cylinder of each pair are extended past its periphery and overlap the sides of the opposite cylinder, as shown atC6 C6, and as the cylindersare arranged a slight distance apart it Willbe readily seen that the 4ends of thespace areclosed by the said overlappingportionsCG C6. Each cylinder also has its periphery covered vwith a thin `layer of aluminium, asshow'in at O7 C7, for the purpose of preventing the collection of foreign matter, such as rust, dec.

The shaft of each cylinder is provided at its ends with a bore B2 BS, which communicates with its cylinder and forms an inlet and exhaust port, respectively, to and` from the cylinders. The ends of the shafts having the bore B2 are provided with stuffingboxes B4, through whichis projected the end of an inlet .pipe ornozzleiD, whose outer end is connected to a 'l'.-jointhaving a steam and water pipe D D?. connected thereto, each of which being provided with a valve d d2, as

By connecting thecylinder with the water and steam pipes I am enabled to quickly regulate the temperature of the cylinder whenever required,and should they betooihot the valve'd' in the steam-pipe .is` turned oii,

`closing the inlet of steam, and the valve d2 in the cold water opened, which allows asufpply of cold water to enter the cylinders until the temperatureis reduced. It will thus be seen that I provide avery simple and economical arrangement of pipes wherein Iamntilizing one pipefor conducting the steam and hot water direct to the cylinders.

In order to adjust'thecylinders laterally to regulate the width ofthe space between each pair, I arrange in each racway a block E, having a threaded aperture earranged cen trally therein, in which'is designed too-perate the threaded end ofia boltF, that bears against the journal-box B, and in order to hold these blocks against lateral movement I provide each with pawls f j', that engage IOO wheels H H', which mesh with idlers J J, heldv upon stub-shafts J' J', secured to the frameplate A', the lowermost idler meshing with pinions K K' on the lower shafts B'.

A hopper L is positioned in the upper end of the frame and has its inner face lined with fire-brick L', as shown.

From the foregoing description it will be readily seen that I provide a very simple and economical form of sheet-glass-forming machine, and by reason of having the steam and cold-water pipes terminating in one common pipe the rotation of thev cylinders is not impaired and the temperature of the cylinders may be regulated by regulating either of the stop-cocks. n

It may be stated here that I prefer to arrange the inlet end of the shafts with studing-boxes to prevent the escape of steam, and in practice I also intend to provide one of the lower cylinders with a cutting edge OXfor the purpose of severing the sheet of glass as it leaves the machine, and thus deliver it in plates or sheets of even length.

Having thus fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a glass-making machine, the combination of a frame composed of the side plates, each of which having slots or raceways arranged in the edges thereof, the said slots hav- ,ing ratchet-teeth formed'therein, boxes arranged in the said slots and having shafts journaled therein, cylinders held upon said shafts, blocks carrying pawls that are adapted for engagement with the said ratchet-teeth, and a screw operating in the said blocksand adapted to engage the said boxes whereby the said cylinders may be adj usted laterally, and means for revolving the said cylinders, substantially as shown and described.

upon the inner and outer edges thereof, boxes arranged in the said slots, shafts journaled in the boxes, cylinders held upon the shafts and arranged in pairs in the frame, one cylinder of each pair having endplates that overlap the ends of the opposite cylinder, thereby producing a slot between the cylinders, blocks arranged in the grooves and having pawls for engagement with the ratchet-teeth, screws operating within the blocks and adapted to bear against the boxes, whereby the width of the slot between the cylinders may be increased or decreased,the said shafts of the cylinders having ports arranged therein, and one end provided with stuffing-boxes through which pass pipes, gears mounted upon the opposite ends of the shafts, and idlers journaled in the frame and adapted to mesh with the gears of the Shafts, and means for revolving the cylinders, substantially as shown and for the purpose set forth.
