To all whom it may concern/.-

` Be it known that I, Jol-IN L. MALONEY, a States of America, and a residentl of Bellaire, county of Belmont, and State `of Ohio, have invented certain new -and vuseful Improvements in -Machines for Forming Sheet-Glass,` of which thefollowing lis ra specification.

My invention relates to new and useful improvements in machines for forming sheetglass; and itI has for its chief object to rovide Va machine for forming sheetglass W ich ture ofthe metal is provided with means whereby the temperathe temperature of the rolls may be'regulated.

vide a gravity-fed. machine of the character mentioned Awhich is ada ted to roduce sheets of glass of an even t 'ckness t oughout.

'With these and other objects in view my inventionfinally consists in the particular construction, arrangement, and combination j scribed, reference being had to the accomarts,` which wil hereinafter be fully de- -panying drawin s, forming a partei this speci- "fication,inwhic f taining lubricatin material.

'mounted in the wall o 4 .proper point is a metal-pouring spout 2, be-

Figure l1 is a side elevation of the invention. Fig. 2 is a front elevation of the same. Fig. 3 is a section on the line 3 3, Fig. 1. Fig.

A furtherobject of the invention is to prol l shaping clamp 16. rlhe opposite jaw of said 4 is a perspective view of a hopper for con-4 Fig. 5 is a pere spective view of t c shapingclamp, and Fig.

6 is a cross-section of the glass-pouring spout.

Referring to said drawings, n which like referencenumerals designate l-lilre parts throughout the several views, Linfdicates a frame su ported at,its rear side by or against the wall of the meltin -furriace Suitably sai-id fu'rnace at a neath which said frame 1 is located. Journaled said frame 1 is a series of sets of rolls arranged in vertical ahnement,y each set comprising a roll 3, journaled in. stationarv bearlngs 4, and a roll 5, j ournaled in movable bearings, the latter movable in longitudinal guide-grooves 7, provided in the side rails 8 of said frame. -The under side of each movable Abearing 6 is provided with .a tongue 9 for v slidin 1n the groove 7, and on the outer end lof eac movable'bearing is a lug 1l,in which is revolubly mounted or swiveled theend of atented Dec.. 25,' 1906.

an adjustings'crew 10, which -is projected through a threaded opening in a stationary lug 12, mounted upon the side rail 8. By

manipulating said adjusting-screws 1@ the relative distance between the rolls .3 and 5 may be regulated to govern the-thickness of the sheet of glass being formed The ends of the rolls 3 are provided with ilanges 13, which slightly overlap the ends of the rolls touclose the ends of the space between said ro s.

Rigidly mounted on the opposite-'ends of the top of'he frame 1 are supports 14, on which is pivotally mounted a longitudinal plate 15, which normally stands vslightly tilpped backward,as shown in Fig'. 1, said p ate forming one of the jaws ot a metal clamp consists of a plate 17 similar to the plate 15, pivotally 'mounted at each end upon rods 18, which. are pivoted at their lower ends yin lugs 19, mounted upon said frame 1^. A

suitable handle 20 issecured tothe plate 1:7

byineans of whichsaid plate is forced forl ward to `flatten the edge 'ofthe molten body of glass as it begins to pour from the` spout 2. Asis obvious, by forcing thel plate 17 forward the front end of the molten body is flattened between A said pivoted plates, which when forced together assume substantially vertical positions, so that it is readily received between the upper rolls 3 and 5. The plate 17 having been forced forward is withdrawn topermit the metal to pass between the jaws of the clamp to the rolls with#` out 'hindrance or interruption. l The different sets of rolls which arev driven by belts 21, connected with suitable driving mechanism', are not intendedA to serve conveying the `metal downward, but are tended to'shape the metal and to form a sheet of an even thickness throughout, the 'metal being carried downward by gravity.

Located on eachside of the` rolls are two pipes-22 and 23, one for cold air and the other for hot blasts, and connected with said pipes are branch pipes 22 and 23', which extend inward over each set of rolls and have'on their inner ends pipes 228L and 23a, respectively, which lie arallel to the rolls at each side of the path o travel ofthe metal. Each of said pipes 22a and 23a is provided with. a

line or row of perforations (designated 22b and 23h) in the face thereof, through which mrt@ Aimmediately as means for l oo ` erably of tiling, which when lowered upon the l vated the rate of the How of thenretal is lployed for the purpose, after which said vframe 1 over each roll or at o] posite sides oi" rations, respectively, cold and hot blasts may l be directed upon the metal to regulate the temperature thereol". Valves 22 and 23C l are provided in. the branch pipes 22 and 23, as shown. Also connected with said pipes 22 and 23 are branch pipes 22Cl and 23d, which i carry upon their ends perforated pipes 22e l and 28e, through which, respectively, cold and hot blasts of air may be directed upon the rolls to regulate the temperature thereof. Havingpassed through the last or lower set of rolls, .thelnetal may be cut into sheets by any ofthe various methods ordinarily enrsheets are perinittedto slide down an incline 24 to a suitable point for handling.

' The spout 2 is mounted at a point to receive the nietal from the pouring-mouth 25 of the furnace, and it has pivotally mounted in one of its sides 26 a lever 27I freni the inner. end of which depends a heavy block 28, prefbottorn of the spout e'ectually closes said mouth 25 and prevents the liow of nieta] from the furnace. By means ofsaid lever the block is raised or elevated to allow the metal. to flow through the mouth, and by ad-l justing the height to which said block is eleregulated Mounted upon supports 29, attached to the the path of travel of the metal through the rolls, is a hopper 3() for holdingr a' suitable lubricating material, such' as sawdust or ground Wood, and for feeding said material to the rolls through. the iced-opening 31 thereof, k

l'laving thus lfully described my inventiol what l claim as new, and desire to secure b Letters Patent, isl 1. In a device of the enaracter deserlbed, the combination with a glass-melting furnace, of a traine mounted in juxtaposition to the furnace beneath the pouring-mouth thereof, a pluralltv of sets oi verticallyalined rolls mounted on said frame, means for vadjusting the rolls oi: each set with relation to each other, a metal-shapiiunr clamp above the upper set of rolls, and a series of blast-pipes arranged for regulating the temperature of the rolls and of the metal passing therethrough.'

2. ln a devlce o1 the character descrnwu, the combination with the glass-melting furnace, o1" a freine mounted in juxtaposition to the furnace beneath the pouring-mouth thereof, a plurality of sets o'l vertically alined gravity-fed rolls, mounted on said frame, a metal-shaping clan1p, a series of' suitubly-arranged blast-pipes, whereby the temperature o'l the rolls and of the 'metal passing through the rolls may be regulated and valves 'for controlling the blasts emanat iup; from said pipes.
