GAPlPING- OFF DEVICE.

To all whomt't may concern:

Beit known that-I, HARRY F. Hrrunn, a citizen of the United States, residing at Mount Vernon, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in Capping-Cit Devices, of which the following is a specification. v

The invention relates to capping-oil devices for capping off glass cylinders by means of an electrically heated wire. It has for its principal objects; the provision of a device of the. character specified wherein the wire'is automatically maintained in engagement with the cylinder with a fixed and predetermined amount of pressure; the promsion of wire supporting means whereby the slack incident to the lengthening of the wire when heated is yielding-1y taken up; and the provision of an arrangement of the Wire.

' wherein the entire circumference of the cylelectrioity,,andis secured at one-end. to the inder is ex osed to contact with the wire.

One embodiment of the invention is illus-- in the accompanying drawmgs,

trated wherein:-

Figure 1 is a side elevation of the device,

Figure 2 is a side elevation of the reverse side of the device,

Figure 3 is an end view, and

Figurev 4 is a detail section through the reel showing the arrangement of the spring.

Referring to the drawings, 1 is the supporting frame work of the apparatus which framework is' provided at its rear end with a handle portion 2 adapted to be grasped by the hand. Mounted'rotatably upon the sup.-

port l is the wheel or real 3 providedwith a groove .4: (Fig. 3) for receiving)' the wire 5 This wire 5 is of small-diameter sothat reel, while the other end "is adapted to 'encircle the glass cylinder to be capped. oil. The loose end 6 of this wire after 'iassing around the cylinder crosses the wire as indicated in Figure 1, and is secured detaohably to the screw 7. A pair of metal blocks 8 and 9 are secured to the front end ofthe support 1, and current'is applied to such blocks by means ofthe wires 10 and 11 leadin to a generator of some-description. The b ook 8 is provided with a passage 12 (Fi 3) through which the wire passes, and the. lock 9 is provided with a groove 13 (Figs l and 3) through which the end 6 of Specification of Letters Patent. Patented Mar, 12, 1912, Application filed December 19, 1908. Serial llo. 468,275.

the wire is carried before it is wound about the holding screw 7. By reference-toFig. 3 it will be seen tliat'the opening 12 and the groove 13 lie in different planes so that the ends of-the wire pass ea'chother Without contacting. It will be apparent that by making the ends of the wire cross or pass 'yieldingly applied to the wire 5 to hold it tight aboutthe cylinder, and take up any slack due to the expansion of the wire after the end 6 thereof has been secured in position about the holding screw 7.. The device is thus adapted to automatically maintain the Wire in engagement, with the cylinder with a fixed and predetermined amount of prcssure, and is adapted to operate in connect-ion with cylinders of varying diameters. The flow of current through the wire coir veniently controlled by means of a switch 15 mounted upon the side of the support 1,

which switch is preferably of the type shown wherein the'flow is controlled by means of ,a'pair of push buttonslfi and 17, which constructionis well known in the art and needs no further description. The various advantages incident to the construction (will be apparent to those skilled in the art.

Having thus described'my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the following l. A capping ofi device for glass cylinders comprising a circle of wire having its ends crossed and in contactwith the cylind-er at the point of crossing but out of contact with each other at snub point, a. reel to,wh1ch one end of the wire is attached, a 5];1H'lg tending to rotate the reel for hold- -ing the-reel in teusion when applied toe cylinder and means for sending a Cl'lli'tltt of electricity through the wire.

2. A capping-off device for glass cylinders comprising a support, a wire secured thereto 'inpositionsuch 't-l'iatwh'en in opt-irative position the ends of the wire pass and overle each other while yet in contact with the cy inder et such point-of assing but maintain out of contact with one other; and connections for sending i current of .e1e c;
