Specification of Letters Patent.

Patented July 7, 1914.

Application filed May- 20, 1909. Serial No. 497,296.

To all whom it may concern Be it knownthat we, JOHN H. ROADMAN, of Monongahela city, Pennsylvania, and WILLIAM M. DRAvo, of Belle Vernon, Pennsylvania, both citizens of the United States, have invented a certain new and useful Take-Down Sling for Handling Glass Cylinders, of which the following is a specification.

Our invention especially relates to the art of mechanically making window glass, and its primary object is to provide convenient means for handling the large glass cylin ders blown and drawn by machinery, especially to remove the same from vertical position after completion of the drawing process.

The invention is shown in several simple forms in the accompanying drawing, in which Figure 1 is a perspective view showing the preferred form of the device, and Figs.

2 and 3 show respectively modified forms.

Upon the completion of the process of drawing a glass cylinder, it has been a difficult problem to remove the same from its suspended vertical position over the glass and deposit it in horizontal position, upon holding devices, for cutting up the cylinder into sections. In such apparatus as shown for example in the patent to Schmertz No. 890,306 of June 9th, 1908, there is employed a suspension cable upon which are a pair of hooks adapted to engage the cylinder and swing its bottom outward for lowering into horizontal position. There has been some difficulty in placing and, adjusting these hooks in place, since they are not free-to turn to horizontal position without slacking the cable, and for other reasons. In our invention, the cable 4 carries a trolley 5, by which the sling or holder is suspended. In

Fig. 1, this device is shown as comprising a rigid handle 8 engaged by sliding rings 7 on the chain 6 and the handle provided with a stop 9 as shown. The handle has attached to one of its rigid forks 10 ailexible metal strap lllprovided with wooden guard blocks 12, and its free end has a separable fastening in the form of a slot 13 to engage a pin 14 on the other fork of the handle. By this construction the sling may be turned-in its substantially as described.

support and may be brought to horizontal position, slipped around the cylinder and adjusted to place and locked, after which the mere upward pull of the supporting chain 6 will lift the handle to vertical position out of the way. This enables the work-- men to attach the sling or strap to the cylinder with ease and from either side, without drawing down more slack of the cable.

In the modification of Fig. 2, the strap 11 is suspended by handle 16 which is pivoted at 17 to a suspending rod 15 on the block 5, and the strap 11 has simple hooked ends 18 for closing. In the modification of 'Fig. 3 the handle 19 of the strap is rigid and prior devices, of a more secure hold on the cylinder, a more easy adjustability, cheapness, and the capability of bringing the handle to horizontal position and then automatically lifting the handle out of the way as the pulling strain is applied. It will be noted that the flexible strap is rigid in a lateral direction so that it can readily be moved by the handle and this handle may be of any desired length so as to avoid the necessity of getting too near the hot glass.

What we claim as new and desire to secure by Letters Patent is:

1. Apparatus for taking down glass cylinders, comprising a strap adapted to be passed around a glass cylinder to be taken down and having means for effecting a separable connection of its ends, a handlefixed to said strap and projecting radially therefrom, and a suspending device .for the handle, said handle and strap being substantially rigid when moved in the direction of the axis of the cylinder to be taken handle intermediate of its ends, whereby the handle and strap may be turned from-a-vertical to a horizontal position, the handle and strap being substantially rigid when moved in the direction of the 'axis of the cylinder,

3. In apparatus for taking down glass cylinders, a strap adapted to surround the cylinder to be taken down, a handle connected to said strap and extending radially therefrom, and a supporting device having a. slidable engagement with the handle, the handle having means for limiting the sliding movement, and said handle and strap being rigidly connected with respect to movement in the direction of the axis of the cylinder to be taken'down, substantially as described.

4. Apparatus for taking down glass cylinders, comprising a flexible metal strap adapted to surround the cylinder to be taken down and having a non-metallic inner portion for contact with the cylinder, a handle fixed to said strap and extending vertically therefrom, and supporting means connected to the handle, the handle and strap being substantially rigid when moved in the direction of the axis of the cylinder, substan tially as described.

5. A device for taking down glass cylinders, comprising a sling having separable ends and adapted to surround the glass cylinder, ahandle fixed to the cylinder near one of its ends, and a suspending device having in oasoa swing connection with the handle, said handle and sling being constructed and connected to be substantially rigid when moved in the direction of the axis of the cylinder, substantially as described.

6. A. device for moving freshly drawn glass cylinders from a vertical to a horizontal position, comprising a sling member having separable ends and adapted to surround the said cylinder, a rigid handle fixed to said member to maintain a rigid relation thereto when moved in the direction of the axis of the cylinder, and a suspending device having a swing connection with the handle, substantially as described.

In testimony whereof we have hereunto signed our names in the presence of the two subscribed witnesses.
