Specification of Letters Patent.

Patent-e June 1' 3, 199.

Application filed Key 10, 1918. Serial .ll'o. 233,687.

To all whom. it may concern Be it known that I, J our: MURPHY, s citi zen of the United States, residing at Hertford City, in the county of Bleclrford and State of Indiana, have invented a new and useful Improvement in Splittingliuclrs for Glass Cylinders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is an end elevation of a splitting buck embodying my invention, and

Fig. 2 is s. sectional elevation of the some.

My invention has relation to splitting bucks for use in splitting glass cylinders or rollers in the manufacture of glass sheets.

The object of my invention is to provide a simple and convenient form or" buck upon which the cylinders or rollers can be placed preparatory to splitting without danger of breaking them, and which has means for fitcilitating turning of the cylinders or rollers to bring them to the most adv-untsgeo splitting position.

he nature of my invention will be best understood by reference to the accompany ing drawings, in which I have shown a preferred embodiment thereof, and which will now be described, it being premised, however, thot various changes can be made in the details of construction, arrangement and combination of the several parts, without departing from the spirit and scope of my invention, as defined in the appended claims.

In the drawings, the numeral 2 designates suitable standards or uprights which are arranged in pairs, three of such pairs being shown. They are spaced from each other and are connected in any suitable manner so as to form a rigid buck frame. The opposite standards or uprights are connected at their upper portions by flexible 3 of some suitable material, such as cotton belting, or canvas, these strips forming a cradlelike support for the glass cylinders or rollers when placed on the buck.

At each end of the buck, ll provide 5: pair of antifriction wheels or rollers 4, which are mounted on opposite end portions of a bar 5 secured to it vertical member 6, which is mounted to slide vertically in a guide 7 attached to the buck frame. The two vertical members 6, at opposite ends of the buck, are rigidly connected by a bar S. is be" is connected by links 9 with e trezulle 1O journalcd in the lower portion of the buck frame and having a treadle lever 11 fulerumed at 12.

In the use of the buck, the Wheels 4 are normally in the lowered positions shown in so ratory to splitting, it is necessary for the splitter to examine the cylinder for defects, and to turn it to a position where the line of greatest defects is close to the line of split, in order to reduce Waste in subsequent cutting. Heretoforc, this has been manually lifting one end of the cylinder and turning it While it is supported on the split ting buck at its opposite end. This is somewhst dir'iicult, especially with large cvlinders. the splitter simply octuotes the treodle to raise the bar 8 and thereby the Wheels 4, thus bringing the latter into contact with the cylinder or roller and raising it ofi from the b its. The cylinder can now by a slight pressure of the fingers; and can be readily examined and brought to the most advantageous splitting position. The cylinder is then lowered onto the flexible supports end is split in the usual manner.

If the cylinder is to be again split, the Wheels or rollers are again elevated and the cylinder turned thereon to new splitting position.

The advantages of my invention will be so other for carrying them while being in spected and turned to proper splitting posi-f manner the operations are lion. in this greatly facilitated. The wheels rollers can be made of any suitable materiel, such 1% as wood.

I claim: 1. A splitting buck for lass .c: comp-ising llexiole supporting means for the cylinders While being split, other vertirally movable supporting moons upon ih cylinders may supported and freely rotated preliminary to splitti i said other substanmine-ting vh ich oporti 11g done by 7c in accordance with my invention, 75

be turned 8t splitting, and the 955 the points Where they contact with the Mo cylinder when in cylinder engaging position,

i and means located at one end portion of the buck whereby the last named supporting means may be moved into and out of cyl-' inder-engaging position, substantially as described.

2. A splitting buck for glass cylinders, comprising flexible supporting means for the cylinders while being split, other vertically movable supporting means upon which the cylinders may be supported and freely rotated preliminary to splitting, a foot treadle at one end of the buck extending in the direction of the length of the buck, and actuating connections between said treadle and the movable supporting means, said treadle and connections enabling the splitter to manipulate said support While turning the cylinder with the hands, substantially as described. 1

3. A splitting back for glass cylinders, comprising a frame having transversely eX- tending flexible supporting means for the cylinders while being split. a pluralityof sliding members mounted on said frame. a pair of wheels journaled on each of said mem- 'bers, connections between said members, and an actuating device for simultaneousl raising and lowering said members from the position below the plane of the flexible supporting means t a cylinder engaging position above said plane; substantially as described.

in testimony whereof, I have hereunto set my hand.
