Application filed April 7, 1891. Serial No. 388,049. (No model.)

i T0 all whom t 17mg/ con/cern,.-

Be it known that 1 JAMES NV. BONTA, a citizen' of the United States, residing at lVayne, in the county of Delaware and State of Pennsylvania, have invented certain new'and useful improvements in Apparatus for Rolling Plate 'or Sheet- Glass, of which the following is a specilication.

My inventionhas relation to inacliinesfor rolling plate-glass; and it has for. itsvobgect to so construct the machine that both sides ot the plate can be successively rolled, and thus do away with the undue grinding necessary when the glass is rolled only on one side, the rolling of both sides of the glass removing the irregularities necessitating such grinding.

My invention .accordingly consists of the combinations, constructions, and arrangements of parts, as hereinafter more particu' larly set forth in the specification and pointed out in the claims, reference being. had to the accompanying drawings', wherein* Figure 1 is a side elevation, partly broken away, showing a machine for rolling both sides of plate-glass in accordance with my invention. Fig. 2 is a longitudinal section, partly in elevation, of the same. Fig. '31s an end view or elevation of the saine. Fig. 4 is a like View, partly sectional, illustrating the rotation of the plate-glass and platens. Figs. 5 and 6 are respectively an end View and a side elevation of the screws or Worms for lifting and lowering the plat-ens and glass. Fig. 7 is a detail View, drawn to an enlarged scale,

showin g end elevation of su pportin g-journals and locking mechanism for the platens. Fig. S is a longitudinal vertical section ot same with part of tlie platens in elevation, showing. the locking or movable tubular sleeve released froni the platens. Fig. 9 is a horizontal section of the same. Fig. ldis a like view showing the lockingtubular sleeve in engagement with the platens. Fig. 1l is a broken elevation of the platens. Figs. 12 and 13 are elevations broken away, the former showing stop-pin and one position of. separating-strip for the platens and the latter showing said pin and another position of said strip. Fig. 1l is across-section of laterally-moving guide rails or supports for thc platen when'moving into position iii the in aeliine for rotation, said figure showing such rails or supports in their of actuating mechanism for laterally moving the guide rail or supports for the platen, the saine being shown in two different positions. Fig. 23 is a section on line 1 l, Fig. 21; and Fig. 24 is a like view on the line 2 2, Fig. 20.

A represents the housings or frame ot' the machine, which preferably carries an engine vor iiiotor B and has rollers or wheels a, ru'nning on guides or tracks a', so as to .make it portable; but, if desired, it may be located in a fixed position.

The housings or the machine A consists of a long lower part (02, having at its upper edges fixed guides or roller-supports a3 and laterally-moving guides or roller-supports C,

the latter being near the rear end of the niachine, and are of a length approximating that of the platens D D used in the machine, and upon these guides or supports said platens are reciprocatedto roll the plate-glass.

E E represent vertical standards secured to the housing part a2, and have open-top bearings e, suitably formed to receive the journals f and eccentrics f on said journals of a pressure-roller F, which is in gear with the driving-shaft b of engine B, by means of wheels]L12 and Il. The presser-roller F is provided with arms f 3 f f3, the upper end of which has a pin or other connection f4, with slots or apertures f5 in a curved bracket f6 concentric with the axis of the presser-roller, said pin or connection f4 bei iig removable from the bracket f6, so that by moving said arins fsf3 to and fro or radially the eccentrics f on the presser-roller' journals f are moved to set the roller higher or lower to snit different thicknesses of vplate-glass and also to vary the rolling pressure of the saine.

The platens D D are provided with side racks d for engagement with the gear-wheels f7 fl on the presser-roller F, and at one end said platens are provided with side recesses IOO CZ to receive the ends g of racks y', pivoted at g3 to racks G, which are located on the tixed guides or supports a3 in advance of the platen. a4 a* represent vertical standards, which support a vertically-sliding frame ll, of any suitable or desired construction, hung upon variable speed or. other screw worms-or actuating mechanism t for raising and lowering said frame, said actuating mechanism being 1o mounted upon a shaft h', having its bearings in standards a?, so as to be movable longitudinally by means of a shifting-lever h2, and has a bevel or other gear wheel h3 in engagement with like Wheels h2, h3, and b4 with the motor driving-shaft l); The wheel h3 is splined to shaft 71.', so-as to admit ot the longitudinal movement of the latter vwhen shifted and when rotating to lift or lower frame li, as hereinafter described, and said wheel. is held zo in position to always engage the Wheel b2 by a bracket 7L on the motor B.

In standards a4 is journaled a shaft l, upon which at one end is splined the bevel-wheel 1'., having a shiftinglever "to cause said wheel 2 5 i to engage with and disengage from wheel b3. At the other end of shaft i is a gear-wheel t2 and a link i3, which engages the stud-shaft t4 of an idler-gear i5, said stud-shaft i* having an end bearing in a slot t in one end of the 3o frame H, as more plainly shown in Fig. 3.

The lower ends of frame H on each side thereof are provided with inside and approach# 1 ing short journalsor studs h5 and with tubllll boxes he, which inclose said journals,

3 5 the forwarder free ends of the latter projecting beyond said boxes. Y(See more plainly Figs. 7 to l0, inclusive.) g

Vithin boxes hand between them and the journals hare tubular sliding sleeves hl, hav- 4o ing suitable slots hs to admit of their sliding movement. Mounted in said sleeves and working in slots hg of boxes hare blocks 71.10, on which are journaled eccentrics 7L upon vertical shafts 71.12, mounted upon the ends of frame H. The upper ends of shafts' h12are provided with gear-wheels h, engaging with a sliding rack shifting or actuating oar h, so that by moving thelatterin one direction the eccentricshll and blocks hw are actuated to 5o slide the sleeve h7 in one direction, and by moving the bar h14 reversely said eccentrics and blocks are actuated to slide the' sleeve hl in an opposite direction for purposes herein after-described.

Loosely mounted upon the inner ends of box-es h6 are gear-wheels hl, which engage with the idlers t5, and thence by wheels t2 with shaft I. Said Wheel 7115 at suitable intervals on their inner sides are provided with tSo-stop-pinsh16 (see more plainly Fig. 3) for a purpose hereinafter to be described.

The laterally-sliding rails or supports CA between supports c and the top edge of the housin The slots c3 are partly straight and partly angular, as shown more plainly in Figs. 16 and 17, so that when plates c4 are moved in one direction the angular part of its slots c3 actuates the studs c therein to lat orally move the roller guides or supports C in one direction, and when reversely moved said supports C are laterally moved in au opposite directiou.- A

To actuate the plates c4 they are provided with depending studs o5, passing through slots 'c6 in the top of the housings, and provided with a bar or link connection c7 and a shifting or actuating lever cs. (See Fig. l.)

"he platens D D are on their ends and at their middle provided with seinioircular projecting journals or supports dg'for engagement with the journals h5 on the ends of frame H. Both platens are identical in construction, and one of them is always in position on the end of the frame H, as shown in Fig. l, andthe other upon the fixed guides c3 in front of the presser-roller F normally to begin operations, which are substantially as follows: The presser-roller F is adjusted for the thickness of the glass and the pressure' required for rolling, and after the plateglass is laid upon the platen in front of the presserroll, which glass is indicated at X, the pivoted racks g are engaged with the recesses d' in the platen, the movement of the presser-roller enf gages the racks d of the platen to move it in the irection of arrow Land as it is so moved the glass is rolled on one side. The platen so moves until it comes under the platen D', supported upon the frame H, theracks gaud Gbeingprovided and keeping in engagement with the presser-roller gears f7 to admit of thevfull length -of such movement. As soon asthe platen .D arrives at such described position the pivoted racks g are raised out of engagement with the platen by means of a lever g3, (see more plainly Fig. 2,) meanwhile the rotation of the presser-roller having been stopped or its actuating mechanism being thrown out of gear. The shaft 7L is then shifted tolower the frame H and platen D until the'latter IOO IIO

rests upon 'the platen D, with the journals h5 Vrotated without raising them to an undue height. lVhen sufciently raised, the move- :ment of shaft h is stopped and the shaft I is put into operation to rotate wheels hk", the stops or studs h1 of which being in engage-l ment with the platens, as shown in Fig. lt, the latter are rotated to bring the platen D on top, reversing the position of the platens and bringing the unrolled side of the glass upi rolled side of the glass uppermost, and means permost. The shaftv h is then actuated to lower the platens, the lever cS being meanwhile shifted to return the supports C to their normal position to receive the platens. Bar h14 is shifted to unlock the sleeves 717 from the platen boxes or bearings (Z2, and the shaft h is then actuated to raise the upper platen D from the lower one D', the glass remaining upon the latter. The pivoted rack g is then inoved'into engagement with the recesses in platen D', and the presser-roller F is then started, but in a reverse direction to cause platen D to move in a direction the opposite of that indicated by arrow 1, Fig. 1, to roll the other side of the glass.

If desired, the platens may be furnished with pivoted clamps 7a and Za', the former being on one and the latter on the other platen, (see Figs. 1S to 20,) for clamping the platens at their sides when rotated. r1`hese clamps Z; may be connected to suitably-arranged vangle-leversI/t12 k3 by links 7a4 las, having reacting springs k6, the free ends of the levers k3 being in line with the inner end of the clamping tubular sleeves Zi?, so that when the latter' are moved to clamp the studs or journals (Z2 of the platens said sleeves will also actuate the levers k3 to automatically cause the clamps 7.: to engage with the studs k', and when said sleeves are released the reacting springs k6 will act to cause.v the levers 7a2 k3 to move to unlock the clamps k from the studs 7o.

Instead of using the actuating mechanism for the movable guides C, as above described, and shown in Figs. 1l to 17, a block Zwith eccentric Z, having a gear connection Z2 with a shifting rack bar, may be substituted, as shown in Figs. 21 to 2i. It will be noted, therefore, that the details of construction of the machine may be greatly varied without departing from the spirit of thel invention; and I do not therefore limit myself to the construction and arrangement of parts as shown and described, as the essence of the invention is the provision of mechanism for rolling both sides' of plate-glass successively.

In anotherpendingapplication of even date herewith I have claimed the method herein described for rolling glass plates, said application having Serial No. 388,050; and hence I do not herein claim such method. sired, suitably-located heating-pipes m fm may be provided for the platens to prevent chilling of the glass.

What I claim is* 1. In a plate-glass-rolling machine, the combination of a presser-roller, a movable platen passing the glass under said roller, avertically-sliding frame having journals carrying a second platen, devices for bringing both of said platens together and locking their journais, means for raising and lowering said locked platens, devices for rotating the platens and for releasing the same with the unfor moving the platen containing the glass.

through or past the presser-roller, substantial] y as set forth.

2. The combination of a presser-roll, a power mechanism, a movable platen, a normally-stationary platen, and devices for locking the platens together, raising and lowering them, and rotating them to reverse the sides of the plate-glass relatively7 to the presser-roll, substantially as set forth.

3. The combination of an adjustable presser-roller for rolling plate-glass, a movable platen passing in one direction under said roll, a normally-stationary platen in line with said movable platen when it completes its movement for rolling the glass on one side thereof, devices for locking said platens together and for rotating them to bring said last-named platen to position for passing the plate through or under the presser-roll to roll the opposite side of the glass, substantially as set forth.

4. In a plate-glassrolling machine, a presser-roll, two separate platens, locking devices for supporting said platens with the plateglass between them, and devices for rotating the platens, substantially as set forth.

5. The combination of a vertically-moving frame, journals on said frame for supporting a platen, actuating devices for raising and lowering said platen and a second platen when brought into alignment therewith, and locking devices for securing said platens together and forY rotating them, substantially as set forth.

G. The combination of a vertically-moving frame, journals secured thereto, tubular sleeves surrounding said journals, means for sliding said sleeves, and devices for raising and lowering said frame, substantially as set forth.

7. The combination, with platens D D', means for raising and lowering and for rotating them, of the laterally-moving guides or supports C, substantially as set forth.

S. In a plate-glass machine, a platen supported on end journals, a sliding platen adapted to register with said j ournaled platen, and devices for bringing said platens together, locking them, and rotating the same, substantially as set forth.

9. In a plate-glass-rolling machine, a presser-roller, a reciprocating platen, a second platen supported upon a vertically-sliding frame carrying gear-wheels in engagement with said platen, means for locking said platens together, and actuating mechanism, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
