Description

VUNITED STATES 7 ETHAN ALLEN, OF WORCESTER, MASSACHUSETTS.

PATENT OFFICE.

Specification forming part of Letters Patent No. 55,596, dated J une 19, 1866.

To all whom it may concern.:

Be it known that I, ETEAN ALLEN, of Worcester, in the county of Worcester, State of Massachusetts, have invented a new and Improved Mode of Heating and Soldering Gun-Barrels; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanyin g drawings and letters of reference marked thereon.

Figure 1 is a perspective view of the reboX and bench or table; Fig. 2 is top View of the grate; Fig. 3 is a sectional View of a single nozzle; Fig. 4 is a top view of a pair of barrels clamped ready for soldering, and Fig. 5 is a side view of a clamp.

The nature ot' my invention consists in so arranging a fire-box in connection with one or more gunbarrels that the blaze is blown entirelyT through them, heating sufficiently for tinning and soldering; also, the. mode in con- Iinin g the barrels together.

That others skilled in the art may make and use my invention, I will proceed to describe its construction and operation.

A is the tire-box; B, the grate; C, the lower door or opening; D, the upper cover to the box; E, the wind or blow pipe; F, the double nozzle; G, the single nozzle; H, the table; I, the gunbarrels, and J the clamps.

The fire-box Ais divided near the center, as shown by the dotted lines, Fig. 1, and is provided with a grate, B, as seen in Fig. 2. The grate B is connected to the door G by a link in such a manner that when the door G (which is hinged to the front side ot' box A) is fastened in place the grate B is also secured in the right position for use, and when the lower door, C, is let down to discharge the ashes the grate B is also let down, discharging the contents of the upper part of tire-box A. The lire-box A and table H are supported ou suitable legs,

' (not seen in the drawings.)

The operation is as follows Fire being built in the upper part of the metallic irebox A upon the grate B, and the single nozzle Gr being inserted into the box A in place of the double one, F, which is removed for the time being, a single barrel is placed upon the blocks 7L and h' of the table H and slid over the tube or nozzle G. Wind is now communicated through the pipe E from the bellows, and is forced through the grate B to the iire, and the blaze and heat of the lire are blown through the nozzle Gr the whole length of the barrel through the inside, heatingit sufficiently to tin the side. Having tinned the sides of two of these barrels, they are put together and the ribs placedin the right position, when they are securely fastened together by clamps J, which are provided with set-screws 7c and springs n. The nozzle Gr is now taken out of the tire-box A and the double nozzleF is put in its place, when the two barrels I are put upon the blocks h and h of table Hand connected with the nozzles, as before, when the blaze is forced through both of these barrels at the same time, hea ting them sufficiently to solder. The solder is now applied and the wholeis secured rmly together, `the degrees of heat being regulated by letting more or less blast through the pipe E by a suitable slide made for that purpose. The clamps are now removed and the operation is repeated as before.

The great advantage of this mode of putting barrels together over the old plan of confining them with wires and heating over a tire or by heated plugs will be apparent to any one skilled in the art, for the barrels are heated regularly and very quick through their entire length, and are in a position for the workman to handle conveniently, and the clamps can be used an almost endless number of times, thereby saving no small expense for wire, as well as time, where barrels are manufactured largely.

Having fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is

1. The mechanism, substantially as described, for heating and soldering gun-barrels by blowing the heated blast through them.

2. The clamps J, composed of set-screws and springs, substantially as described, for holding gun-barrels while being soldered.
