' arnnromrnnrans. GLASS ROLLCINGAND Application filed July 6,;

To all-whom it may concern: 1 j r Be it known that .L' RAYMOND F. HAN- COCK, a citizen of the United States, residing at Marion, in the county of Grantand.

State of Indiana, have invented certain new and useful Improvements in Glass Rolling" and Pressing Machines; and I. do declare the following torbe a full, clear, and exact. descriptionof the invention, such]; as will enable others skilledin the art to which it appertains to make and use the same. i

p This invention relates toa machlneafor rolling molten glass into a sheet and :nressing figures into the glass, and one oblect'of 'the invention is to provide a machine in which the molten glass can be easily rolled into a flat sheet and during the rolling proc. ess, a figure formed by a raised portion upon a roller forcing the glassdown into a the molten glass is placed;

Another object of the invention IS'tO so construct the table and roller that a sleeve carrying the raised figure mayv be removably mounted upon the roller and a plate carrying the corresponding recessremovably'carried by the table. I

Another object of the invention 1s to so construct this table that'the rolled plate of glass may be lifted from the table after the roller has passed over the glass thus making it easy to remove the pressed plate of glass from the table.

Another object of the invention is to provide a machine of the character described which will be simple in construction and easy to operate and which will consist of a comparatively'few number of parts easy to assemble and not liable to move out of the 4 proper position.

This invention 1s illustrated in'the accompanying drawings, whereint Figure 1 is a top plan view of the improved machine. I Figure 2 is a view showing the lmproved machine in side elevation. Figure 3 is a transverse sectional View througl'i the improved machine. I

Figure 4 is a longitudinal sectional view through the machine taken on the line l-+l-,

- i of Fig. 3. p i

' This machine is provided'with a table having a top or platform 1 supported by legs or standards 2. A pocket 3 1s formed of the table.

in the top 1 to carry a plate upon which willb eformed aletter or other character 5 for forcing glass into a corresponding recess '6 formed in the sleeve 7 of the roller 8. It should be noted that the plateAetapers downwardly as shown in Figs. 3 and 4 andthat the. pocketf is of .a-corresponding shape so that the nlate may be easily'set into this. pocket. Fastening screws 9 are provided as shown in Figs. 3 and so that this plated can be securely but releasably held in place. The sleeve 7 is held in the proper pos tion upon the roller 8 by fasteners. 10 which are. in the form of machine screws. as

shown in Fig. 3. It will thus be seen that a number-of corresponding plates. and sleeves can be provided and the proper sleeve'and plate put in place according to the letter, figureor other character which it is desired toform in the plate of glass. I I A", Theroller8is carried by. a shaft 11 which extends beyond the ends of the tubular hub 12 of the roller and has its end portions resting upon the tracks 13 which are upon and extend longitudinally of the table top 1.

The table 1 further carries rack bars 14 for engagement by gears or pinions 15 mounted upon'the end portions ofthe shaft-11. It will thus be seen that when the shaft 11 is turned through the medium of theturning handle 16,the roller will be moved longitu dinally of the table and will beretained in the proper position and further caused to rotate properly so that the raised, character 5 of the plate t will alwaysfit properly into the depression or seat 6 formed in the sleeve 7. i

hen this device is in use, the properplate 4 and sleeve 7 are put in place and the roller willbe positioned adjacent one end The molten glass is then pouredonto the table in front of the roller and the roller is caused to move longitudinally of the table through turning of the shaft by means of the handle 16. As the roller moves along the table, the molten glass will be rolled into a sheet of the thickness corresponding to the distance between thetop of the table andthe surface of the roller. When the roller reaches the'position shown in Fig. 4, the raised character 6 will force the molten glass up into the corresponding recess 5 of the plate 4 thus providing a character having the same thickness have the same character, no adjustment is necessary but if diliierent character is to; I be formed, the plate and sleeve Will be re-' moved and the proper ones out in place.

' In order to lift the plate of glass from the table, there has been provided strips 17 which are embedded in the table top. These strips. are engaged by a yoke 18 which has its arms extending 'tlirough openings 1!) formed in the tabletop. An actuating lever or treadl'e 26) is pivotally mounted beneath the table by means of a hanger bracket 21 and has its inner end portion connected with the yoke by means of a link 22. 'By pressing upon the treadle 20, the yoke will be moved upwardly and the yoke Will be forced upwardly through the table top thus elevating the strips 17 and lifting the plate or sheet of glass oil of the table so that it can be easily removed fromthe table. In the bresent illustration the plate has been provided With a raised character and the sleeve provided with a corresponding recess but it is obvious that this arrangement After the sheet 7 teri'al into bedded in said table, a yoke having arms 7 said table, strips embedded in said table and extending longitudinally thereof, a U-shaped yoke beneath said table and extending transversely thereof and having arms extending up through openings in the table and connected with said strips, and means for moving the yoke upwardly to project its arm upwardly through the table and move said'strip's upwardly to lift a sheet of glass ofi' of said table.

A machine of the character described comprising a table, means for pressing masheet upon said table, strips emextending upwardly through openings in said table and connected With said strips, a treadle pivotally mounted beneath said table, and a link connecting said treadle With said yoke for moving the yoke and strips upwardly to lift a sheet of pressed material from the table when pressure is applied to said treadle. I I

In testimony whereof I have hereunto set my hand.

RAYMOND F. HANCOCK.
