Application filed November The object of my invention is to provide a simple and efiicient apparatus for use in taking down glass cylinders which have been drawn from a molten bath, having particularly in mind a structure by means of which the hole-end sling may be more conveniently associated with the cylinderin its vertical position.

Heretofore the hole-end sling has generally been either of the type disclosed in Patent No. 1,102,803 or a plain hoop having no rigid radial handle. In either case dithculty has been experienced in getting the hoop high enough up on the cylinder and in many instances additional operators have been required to shove the hoop up on the cylinder by means of long sticks. In such an operation it is not at all unusual to mar the cylinder so that portions have to be discarded and sometimes the cylinder is broken because of an initial checking due to contact of a cold element upon the hot cylinder.

The device which I have devised obviates these difiiculties.

The accompanying drawings illustrate my invention. Fig. 1 is a diagrammatic per spective illustrating my device and associated parts; Fig. 2 is a side elevation of my improved sling; Fig. 3 another elevation at right angles to the plane of Fig. 2 and Fig. 4 a plan.

In the drawings 10 indicates a sling or hoop conveniently formed of fiveeighths round iron and wrapped with asbestos. Hoop 10 is provided at one side with an eye 11 and flanking this eye, about sixty degrees therefrom, at each side, is an eye 12. Secured to eyes 12, 12 are the ends of a bridle 13, which, at its middle, is suspended from the lower end of a counter-weight cable 1 1 passing up over a pulley 15 and is provided at its free end with a weight 16 which will more than counter-balance the weight of hoop 10.

Secured to eye 11 is a take-down cable 17 which is passed up over an overhead pulley 18 and from thence to a Winding drum 19 which may be manipulated either by an electric motor or by hand, whichever may be more conv nient. Also, secured to eye 11 is a ape" 2(lthe free end of whielr may r ni -elated by workman 5, 1925. Serial No. 67,116.

a The cylinder 22 is drawn by means of a bait 23 supported in a vertically movable cage mounted in vertical guides in a wellknown manner. The cylinder 22 is drawn from a supply of molten glass 24.

The cylinder, when taken down, is to be laid upon a suitable horse 25 and during the draw the hole-end sling 10 is hung at a point of convenient access, as indicated in dotted lines in Fig. 1.

When the cylinder has been cut oil from the glass bath the operator 21 will remove the hole-end sling 10 from its hook and, by hanging it to cable 20, will oppose the pull of counter-weight 16. The relation of eyes 12, bridle 13, eye 11 and rope 20 is such that the hole-end sling 10 will, under these conditions, lie substantially horizontally and the operator 21 may readily slip the sling in this position beneath the lower end of cylinder 22, whereupon, by slowly paying out cable 20 counter-weight 16 will operate to .draw the sling upwardly to any desired position along the length of the cylinder, as indicated in Fig. l. Nhereupon a pull upon cable 17 will swing the lower end of the cylinder outwardly so that, by simultaneous downward movement of the blow pipe 23, the cylinder may be lowered to a horizontal position and. then transported to the horse 25 in a well-known manner.

By this means the single operator 21 is enabled to place the hole-end sling without possibility of marring the lower lengths of the cylinder.

I claim as my invention:

1. A take-down apparatus comprising a hole-end sling, a hoisting cable and guide rope attached thereto, and a counter-weight cable attached to said sling and supported in such manner as to be capable of moving the sling upwardly along the length of a freshly drawn cylinder.

2. A take-down apparatus comprising a hole-end sling, a hoisting cable and guide rope attached thereto, and a counter-weight cable attached to said sling andsupported in such manner as to be capable of moving the slin upwardly along the length of a freshly drawn cylinder, said counter-Weight ca s being attached tothe sling by means ridle the ends of which e ipon Opposite sides of tachment of the guide rope and between the center of gravity of the sling and the said point of attachment.

3. The combination with a vertically movable glass-drawing implement, of a takedown sling adapted to embrace a drawn article supported by said implement, a takedown cable attached to said sling, a counterweight, and a connection between said counter-weight and sling so arranged as to normally tend to move the sling upwardly along said article.

l. The combination with a vertically movable glass-drawing implement, of a takedown sling adapted to embrace a drawn article supported by said implement, a takedown cable attached to said sling, a control rope attached to said sling, a counter-weight, and a connection between said counterweight and sling so arranged as to normally tend to move the sling upwardly along said article.

5. The combination with a vertically movable glass-drawing implement, of a takedown sling adapted to embrace a drawn article supported by said implement, a takedown cable attached to said sling, a control rope attached to said sling, a counter-weight, and a connection between said counterweight and sling so arranged as to normally tend to move the sling upwardly along said article and engaging the sling between the center of gravity thereof and the point of attachment of the control rope.

In witness whereof, I THOMAS F. lVA'rERs have hereunto set my hand at Okmulgee, Oklahoma, this 30th day of October, A. D. one thousand nine hundred and twenty-five.

THOMAS F. WATERS.
