CAPPING-OFF DEVICE.

Application filed August 8, 1922, Serial No. 580,554. Renewed January 4, 1924.

To all iii/tom it may concern.

Be it known that I, GUs 1V. SWANSON, a citizen of the United States, residing at Morgantown, in the county of Monongalia and State of lVest Virginia, have invented a new and useful Capping-Off Device, of which the following is a specification.

This invention is a device of the type used in window glass manufacture, for cappingoff glass cylinders, and for cutting such cylinders into flattening lengths.

One of the objects of the invention is to provide a device by means ofwhich an electrically heated wire is utilized to impose the cracking tension in capping-off and cutting glass cylinders, in the manufacture of window glass and the like. A further object is to provide a device of the character mentioned, in which the heating wire is so disposed that both ends must be free and disconnected from the current, while said wire is being passed around the cylinder to be operated upon, thereby permitting manipulation of the wire and protecting the operator from danger of electric shocks. A further object is to provide means whereby the wire may be quickly placed in circuit with the heating current, or disconnected therefrom, as occasion may require. A further. object is to provide means whereby any slack in the heating wire, after it has been passed around the cylinder, may be readily and quickly taken up, so that the wire will firmly and closely embrace said cylinder, whereby the device is adapted for operation on cylinders of different diameters. A further object is to provide means for anchoring the ends of the heating wire, combined with conductor wires provided with terminals which are movable toward and from the anchored ends of the heating wire, to make and break the circuit to said wire.

The invention will be hereinafter fully set forth and particularly pointed out in the claims. I i

In the accompanying drawing 2-- Figure 1 is a top plan view, parts being shown in section, illustrating a cappingoff switch constructed in accordance with the invention. Figure 2 is a side elevation, partly in section, showing the parts in capping off position. Figure 3 is a similar view showing parts in positions assumed after the heating wire has been engaged with the cylinder, but before the slack has been taken.

up. Figure 4 is an end view.

Referring to the drawing, 10 designates a base of insulating material, preferably of fiber, )rovided with a longitudinal groove or channel 11, in which is mounted a slide 12. Said slide supports a stationary member 13, to which is pivotally connected a clamp memberl l. Said clamp member is held in clamping position by means of a latch 15, pivoted to the member 13 and engaging a pin 16.

The stationary member 13 is provided with longitudinally disposed grooves or seats 17, to receive tubes 18 of insulating material such as fiber, for instance. Said tubes 18 are provided'with notches 19, engaging complemental projections 20 on the member 13, whereby relative longitudinal movement of the tubes and the member 13 is prevented. 1 i

The heating wire 21 has its ends secured to rod-like conductor members 22, extend,

ing through the tubes 18,and provided with reduced portions 23. Said reduced portions are positioned to engage notches 2-1, in an anchoring piece 25, secured to thebase 10, the extremities of said rods 22 being enlarged, as indicated at 26, to form electric contacts.

Secured to the which may be of any preferred or desired construction, controlling the passage of current through the conductors 28, which may be connected to a source of electrical energy by any well-known or desired means. conductors 28 lead to terminals 29, located within a terminal block 30, secured to asnpport 31, which is slidably mounted in. the channel 11. of the base member 10. The support. 31 is provided with a spring-catch 3-32, which engages a notch 33 formed in the slide or support 12, and is positioned to be. disengaged by comm-g in contact with the edge of one of the overhanging plates 34:-

which retain the slide 12 in place.

1n practice, when it is desired to cap a cylinder or to cut the same into flattening lentghs, the operator disengages the latch 15, whereupon the clamp member 14. is free The to swing upon its hinge-support and thereb release the tubes 18 and the conductor members 22 located therein. The operator then throws one of the tubes and its enclosed conductor member, around the cylinder and draws it taut, after which both tubes 18 are returned to their seats in the member 13, with the conductor members in. engagement with the anchoring member 25. The clamp member 14 is then placed over the tubes 18, and locked in position by means of the latch It will be understood that the parts are now in the positions illustrated in Figure 3, the contacts 26 being out of engagement with the contact terminals 29. The operator now slides the member 13 longitudinally of the base 10, the tubes 18 moving therewith toward the cylinder, thereby taking up the slack in the wire 21 and holding the latter firmly and closely around the cylinder. As the member 13 moves along the base 10, the support 31 and terminal block 30 are moved simultaneously therewith by reason of the connection of the catch 32with the support 12, thereby bringing the terminals 29 into electrical engagement with the extensions 26 of the conductor members 22. By the time that this contact is firmly established, the end of theratch 32 strikes the end of one ofthe plates 34, causing the catch to be lifted and disengaged from the slide 12, so that the latter with the parts supported thereby, may continue to move toward the cylinder until all of the slack in wire 21 is taken up. After the wire 2lhas been closed snugly around the cylinder, the operator turns on the current at the switch 27, whereupon the circuit is closed to the said wire 21, and the latter is heated sufficiently to impose a cracking tension upon the glass. In view of the fact that the outer ends of the tubes 18 must be separated by a slight gap,

it will be necessary for the operator to'tap the stick gently from time to time so as to cause the wire 21 to travel a short distance in a circumferential direction around the cylinder, in a manner which is well understood in the art.

The advantages of the invention will be readily understood by those skilled in the art to which it belongs. It will be particularly noted that by means of the electrically heated wire, the capping-off and'cutting of the glass cylinders is greatly facilitated and accurately accomplished. An important advantage lies in the fact that both ends of the heating vwire must be free and disconnected from the current, while the wire is being positioned around the cylinder. This is because the conductor members 22 cannot be removed until the block 30 has beenmoved away from' the ends 26 of said conductor members. Thus the operator is insured against danger of shocks. and at the same time convenient manipulation of the heating of the forms of its use, what; is claimed is l.
