Fig. IV is a top or plan view of a portion of the table-frame 4of the apparatus and the means for elevating the table. Fig. V is a top or plan view, partly broken out and partly broken away, of the wire-'fabric-cutting members of my apparatus. Fig. VI is a bottom view of the parts shown in Fig. V. Fig. VII is a top or plan view of one of the corners of the table-frame and table and showing in connection therewith in section the trip-levers by which the Wire-fabric-cutting knife and the clutch controlling the actuation of the Wire-fabricvstarting rollers are actuated. Fig. VIII is an enlarged view of 'one of the lass-rolling rolls of my apparatus. Fig. I is a view of a modification of the glass-rollin rolls. Fig; X is an enlarged section of the ace of one of the glass-rolling rolls.

1 designates a series of standards which are arranged in pairs at the sides of my apparatus and which may be suitably tied to each other. 'Each of the standards is bifurcated at its upper end, as seen most clearly in Figs.. I and II.

Extendin longitudinally through the apparatus an between the standards 1 are track-rails 2, which serve to direct the travel of a carriage on the table of which is placed the glass to be rolled. This carriage consists of truck-Wheels 3, having axles 4 mounted therein; journal-boxes 5, in which said axles are mounted; a table-frame 6, supported by said journal-boxes, and a table 7, loosely surmounting said table-frame. At

thesides of the table-frame are rack-bars 8, the utility of which will be hereinafter stated.

The table 7 is adapted to receive the glass to be rolled into ssheets, and it is susceptible of being raised and lowered to vary its elevation through the medium of the following mechanism:

9 represents lift-screws which are tapped into boxes, 10, carried by the table-frame 6, (see Figs. I, II, and IV,) and the upper ends of which are positioned beneath the verti-` cally-movable table 7. The lift-screws 9 pass loosely through Worm-wheels 11, that are mounted in the boxes 1() and Which are connected to the lift-screws by splines, as seen in Fig. I, so that the lift-screws may move vertically therein, but are compelled to partake of the rotation imparted to the Worm-wheels. By this arrangement lI provide for the vertical movement of the liftscrews beneath the carriage-table to raise and lower said table when the worm-Wheels are rotated. lFor the purpose of imparting rotation to the worm-wheels I utilize shafts 12, extending longitudinally of the carriage and equipped with worms 13, that mesh with the worm-Wheels, and transversely-extending shafts 14, which are provided with bevelpinions 15, that .mesh with bevel-pinions 16, fixed to the longitudinal shafts. The transverse shafts 14 are adapted to be rotated through the medium of a wrench, crank, or other implement applied thereto for the purpose of imparting rotation to the lon itudinal shafts and actuating the worms V13 or the purpose of rotating the worm-wheels and lift-screws 9.

17 designates slidable boxes loosely mounted in the bifurcated upper ends ot the standards 1 and adapted to `be raised and lowered therein for a purpose to be hereinafter mentioned.

18 is one of a series of glass-rolling 4rolls utilized in my apparatus, these rolls'being of a number corresponding to the number of Each of the rolls 18 is" pairs of standards 1. supported by a shaft 19, the ends of Which are mounted in the journal-boxes 17 ofthe corres onding pair of standards. At each end ofp each roll 18 is a spur-wheel 20, that is adapted to mesh with the teeth of the carriage-carried rack 8, located beneath it, thereby providing for the rotation of said rol s through the medium of the rack and spur- Wheels when the table-carrying carriage is v moved to and fro beneath the rolls, whereby l do.-

table.

the glass is rolled upon the carriage-table dursired elevation of the table, I p ace beneath it removable gage -strips 21, (see Fig. I,) which rest upon'the carriage-frame 6. These gage-strips are introduced beneath the table after it has been raised bythe lift-screws, and when the table is again lowered it descends onto said gage-plates and they serve as supporting members to relieve the lift-screws of strain. 7 represents rider or gage strips removabl mounted on the table 7 and serving to old the rolls 18. elevated from the The strips receive the flattened end portions 18 ofthe rolls.

It is highly desirable in wire-glass-rolling apparatus to use three or more rolls in order that when one' of the rolls becomes excessively heated in use it may be elevated to cool while the other rolls are in service. For the purpose ofso raising either of the rolls I mount their shafts in the vertically-movablel journal-boxes 17 and furnish means for elevating said journal-boxes. This elevatin means in the presen't machine is constructe as follows: 22 represents brackets seated upon the standards 1 atY their upper ends and havin journaled therein shafts 23, that are provi ed with eccentrics 24. These eccentrics are surrounded by straps 25, from which depend lift-rods 26, that are ivoted at 27 to the journal-boxes 17 Fixe -to each eccentric-shaft 23 at one side of the a paratus is a crank-arm 28, that has ivote to it a connecting-rod 29, and fixe to each yeccentricshaft at the opposite end of. the apparatus is a bell-crank consisting of arms 30f and 31, to the former of which said connectin -rod is plvoted. 32 is a throw-rodX pivote to the ell-crank arm 31 and extending downwardly therefrom into connection with a lever 33, by which sald throw-rod is operated. It will be seen that when said lever is -raised and lowered said throw-rod acts' to rock said bell-crank and oscillate the eccentrics 24 to raise and lower the journal-boxes 17 and the rolls 18,

as may be desired. 34 represents guard-k platesthat are mounted adjacent to the ends of the rolls 18 and serve to restrict the outward spread of the glass while it is being rolled -upon the carriage-table. These plates support a lower guide 35 and a pair of upper gul es 36, all of whlch are located in proximity to the roll 18 at the end of the apparatus at which the wire fabric is conveyed downwardly around said roll to be embedded in the glass being rolledhas seen in Fig. III.

. ard 1', just referred to.

37 designatesa guide-roller which is sup.-

ported at an elevation above the guides 36 y -and which is mounted out of contact with the roll 18 beneath it. This guide-roller is preferably supported by a pair of arms 38, ivoted to the standards 1 of the machine, between which said roller is mounted, suitable stops being provided tolimit the downward swin of said arms. Thewire-cloth to be embedded in the sheets ofv glass bein rolled is conducted over the ide-roller an passes therefrom downward y between the guides 36 and between the guide 35 and the f glass-rolling roll.

39 is a pressure-roller surmounting the guide-roller 37 The pressure-roller is mounted in 'guideways 40 and is yieldingly held projected toward the guide-roller by springs 41, mounted in said guideways and bearing against boxes 42, in which the spindles of lthe pressure-roller are journaled. The guideroller -and pressure-roller serve in conjunction with each other as wire-fabric-strai htening members between which the wire abrio is drawn as it is fed in to the molten glass placed upon the carriage-table of the apparatus..

43 designates a slotted plate supported adjacent to the guide-roller 37 and throughl which the wire fabric passes after traveling over said roller. Beneath the slotted plate is a knife 44. that is pivoted at one end to the plate at 45, (see Figs. V and VI,) and which is adapted to swing to and fro across the slot in the plate for the 'urpose of severing the wire-cloth after as cient quantity thereof has passed over the guide-roller 37 to meet the requirement for the sheet .of glass being rolled. The knife 44, is rocked to and fro to shear the wire fabric through the medium of aA rocker 46, having its upper end pivoted to said knife. pivotally connected to the adjacent-standard 1 at 47, and it has connected to its lower end a lever 48, that is pivoted at' 49 to the stand- The lower end of the lever 48 extends downwardly to the side of the carria e-frame 6 and occupies a position in the pat of travel of a4 trip-block 50, adistably secured to said carriage-frame. (See igs. I, II, III, and VII.) This trip-block 1s IOO (See Fig. II.) This rocker is IIS located adjacent to the lower end of the carriage-frame, and therefore it acts to tri the lever 48 for the -operation ofthe e 44 when the carriage has made nearly a complete forward movement while the sheet of glass is being rolled thereupon and the wire fabric is being embedded in the glass. The guide-roller 37 is driven through the vmedium of a drive-chain 51, that operates upon a toothed wheel 52, fixed tothe shaft of ber 53, loosely mounted upon the shaft of the glass-rolling roll 18. (See Fig. I.) Theclutch member 53 is opposed by a clutch-collar 54,

'said roller and which leads to a clutch memslidably keyed to the roll-shaft and backed bya spring 55, that serves to press said clutch'- collar toward said clutchmember 53. The clutch-collar 54 serves to drive the clutch member 53 and causes said member to drive the guide-roller 37 for the delivery of the wire fabric between said guide-roller and the pressure-roller 39. It is therefore necessary that when the wire fabric is severed after the desired quantity has been fed forward forA a sheet of glass that the actuation of said guiderolle'r cease. To provide for such cessation, I associate with the clutch-collar54'a lever 56, that is pivoted at 57 to a bracket 58, supported by one of the standards 1. The lever 56 has a downwardly-extending arm 59, which projects into a position alongside of the carriage-frarne 6 and is in the path of travel of@ an inclined trip-block 60, adjustably secured to said frame. When in the operatlon of the machine the trip-block 60 moves into engagement'with the lever-armV 59, said lever-arm is rocked upwardly and inwardly, thereby causing the lever 56 to shift the clutch-collar 54 away lfrom the clutchmernber 53 in order that said clutch member will be no longer rotated, and therefore the guide-roller37 will be brought to rest and delivery of wire fabric thereover cease. v

It is to be noted that by mounting the tripblocks and 60 adjustably upon the carriage-frame of the apparatus these trip-blocks may be shifted to and fro. The object of this is to provide for the severmg of the wire fabric at the proper time and the cessation of feed of the wire fabric over the guide-roller 37 after the sheet of glass with the wire fabric therein has been rolled without feeding an excessive quantity of the fabric.

The glass-rolling rolls of my apparatus are peculiarly constructed for the purpose of producing absolutely flat and even surfaces upon the sheets of glass rolled thereby and avoiding the waving surface, such as commonly exists in sheet-glass having wire fabric embedded therein. By waving surface I mean a surface in which ridges are present extending longitudinally of the table of the glass-rolling apparatus at the surface of the glass rolled thereon. These ridv es in the glass are produced by uneven coo ing in the sheet of glass when rolled with the glass in molten condition, and in the use of plain rolls it has been found impossiblelto avoid the occurrence of the ridges. It is one of the main objects of my present improvement to avoid the occurrence of the ridges referred to by the use of rolls that will actconstantlythroughout their rolling action to force the molten glass outwardly from the center of the plate, thus carrying the glass at the plates center to its sides before vthe molten glass at the sides becomes sufficiently cooled to prevent the centralportion of the mass. from being forced outwardly by the rollsto the side porerating said knife to sever the in the form of compound curves extending longitudinally of t e rolls, as seen most clearly in Fig. VIII; but they may be of angle form, as seen in Fig. IX, with the crowns of each convolution located at approximately the longitudinal center of the roll. rihe convolutions of the rolls are of flattened form, as seen at A, Fig. X, thereby making the perimeter of each roll polygonal in form.. The result of using a convoluted roll and making the roll polygonal at the periphery and having the convolutions extending in waving lines with respect to the axes of the rolls is that of causing the glass acted upon by the rolls to be spread outward in various courses instead of its being merely flattened out. As a consequence a plate-surface at the top of the glass sheet is secured instead of producing the waving condition of the sheet which results from the use of only plain cylindrical rolls.

Ill/'herel it is desired to produce an absolutely smooth surface upon the glass sheet rolled in my apparatus, a plain cylindrical roll `may be used in the ap aratus in a position to operate upon the g ass sheet and roll it smooth after it has been flattened out by the convoluted roll preceding it in operation.
