FLUXING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 234,195, dated November 9, 1880.

Application filed July 27, 1580.

To all whom it may concern:

Be it known that I, HERMAN MILLER, of the city of New York, county of New York, and State of New York, have invented an Apparatus for Automatically Applying Flux to Metal Sheets intended to be subsequently soldered to form cans or other sheet-metal vessels or structures, of which the following is a specification.

Heretofore when flux has been applied to the seam portions of sheets of metal by hand it has resulted that the flux has been frequently applied unevenly, and in many cases the corner portions of square or rectangular sheets have, in the hands of inefficient workmen, received no appreciable amount of flux.

To obviate these difficulties is the object of my invention.

My invention consists in an inclined fluxing bed or surface, down which the sheet to be fluxed is to travel, provided with devices to feed and apply flux to the edges of the sheet, and with a device or devices by which the sheet is automatically turned or revolved in its passage upon said bed with the result that each edge and corner of the sheet is presented to and fluxed by the fluxing devices.

In the drawings, Figure l is a perspective view of an apparatus conveniently embodying my invention, and Fig. 2 a vertical sidesectional elevation of a set of the fluxing devices and sheet-feeding mechanism.

Similar letters of reference indicate corresponding parts wherever used.

In the drawings, A represents a supporting frame-work of any fit description, upon which is mounted an inclined bed or way, B, down which the sheet or form of metal to be fluxed is caused to travel. This bed is inclined at two angles, lengthwise and sidewise. On either side the bed is bounded by ledges O, the oflice of which is to retain the sheets to be fluxed upon the bed in their passage down the latter.

At either end the bed is provided with a series of feed-rollers, D, which are placed transversely to the longitudinal axis of the bed, and are intended to support and carry the sheets, one by one, beneath the fiuxing devices.

In the sectional view, Fig. 2, will be plainly (N 0 model.)

seen the arrangement of the rollers D, of which there are, for convenience, five in each set. These rollers are conveniently journaled in the bed in such manner that the bearing-surfaces of three of them, for instance, lie below the plane of the bed, while the surfaces of two lie above the latter.

On one side of the bed the rollers are caused to extend out, and are equipped with toothed wheels E, as also shown in Fig. 2. One of the rollers, preferably the central one, is also equipped with a drive-pulley or band-wheel, F, whereby rotation is imparted to the roller in question.

Idler toothed wheels G conveniently transmit the motion of the driven roller to the toothed wheels of the other lower rollers, while the toothed wheels of said lower end rollers mesh with the toothed wheels of the upper rollers and impart to them the requisite movement.

By consulting the sectional view referred to, which shows the above arrangement, it will be seen that revolution is imparted to all the carrying-rollers ot' the set referred to in a direction which will feed and carry the plate, sheet, or form to be iluxed down the incline of the bed and beneath fluxingbrushes connected with such set, and described hereinafter.

The arrangement of rollers is conveniently the same in each set employed, and motion is conveniently imparted from one set to the other by means of a band, I, from the driving band-w'heel F to a band-wheel, F, which is connected with one of the rollers of the lower set of the drawings.

H are aseries of flux-applying brushes, placed in the lower extremities of a series of flux-applying tubes, J, which are either themselves tluX-reservoirs or are suitably connected to a fiux-reservoir or other source of supply. These tubes are preferably hollow pipes, in the lower extremities of which are secured the bristles which constitute the flux-applying brushes H, so that flux poured into the tubes permeates the brushes in the manner common to self-watering brush devices. The tubes are adjustably secured in brush-supports K by passing through suitable orifices therein, and being retained at the desired height by pressure-screws or the like, 0. The brush-supports are hinged at one end, at (I, to uprights from other portions of the frame-work, and ate laterally-proiecting blocks in line over the edges of the bed within the compass of the ledges C, of such weight as to retnain down in the horizontal position, (considered with respect to the bed,) and by the tension of their weight retain the brushes down in working position. These brushes are arranged singly or in series, as shown, on either side of the bed at both ends thereof. and are in line over the seam or edge of the sheet which it is desired to flux.

The flux-tubes being adjustable, it is obvi ous that the adjustment of the brushes may be adapted to the form of the sheet to be fluxed, while the arrangement of the hinged brush-supports is such as to keep the brushes with an even tension down upon the seams.

in the apparatus represented provision is made for the flnxing of square sheets, such as the bottoms or tops of petroleum or other cans, and the present description is directed to such apparatus; but it is here to be stated that my device is susceptible of such obvious modifications as will adapt it for use with other forms of sheets.

A sheet, L, being fed by the operative on the incline at its upper end, the tubes being supplied with flux and the carryingrollers being in action, is seized by the top set of rollers and carried through them and beneath their brushes, whereby flux is applied to two sides of the sheet. As the sheet emerges from the two lowermost ot' the tirst set of rollers it travels by gravity along the inclined bed B until at or near the center of the latter it encounters a stop, M, placed as represented, and is thereby revolvedorcaused toturn over upon its side, as shown in full and dotted linesin Fig. 1 of the drawings, a bulge, N, in the bed, if necessary, permitting this revolution, after which it continues to descend in its turned po sition, and in sneh position entersthe second set of rollers and passes beneath their fluxapplying brushes, whereby tlux is applied to the two sides or seamsof the sheet which were not previously coated by the tirst set of brushes.

Such being the form and construction of the apparatus represented in thcdrawings,it is obvious that it may be modified to enable its action with other terms than square sheets, the principle of the inclined plane and ot' a partial or complete turningofasheetbeingadhered to. Several sets of brushes and rollers and several stops may for such purpose be embodied in the inclined bed.

Having thus described my invention, I claim- 1. In a tnachine for automatically applying flux to forms of metal,au inclined bed provided with devices to apply flux to the form of metal as the form is caused to travel down the bed.

.2. In a tnachine for automatically applying flux to forms of metal, an inclined bed provided with devices to applyflux to portions ofa form of metal as the same is caused to travel down the bed, and also provided with devices to cause the partial or complete revolution or turning of the form in its descent, so as to cause it to suecessively present its unfluxed portions to the flux-applying devices which are located below said turning device.

3. In an apparatus for automatically applying flux to forms of metal, an inclined fluxingbed provided at each extremity with devices to apply flux to portions of a sheet or form of metal, and with means to feed said sheet or form to the tluxing devices, and also provided between the feeding and fluxing devices with a stop or kindred device, whereby the sheetor form is automatically turned or revolved upon the bed in such manner as to successively present its untiuxed edges to the flux-applying devices which are located below said stop.

4. In a machine for automatically applying flux to forms of metal, an inclined fluxing-bed provided upon its surface with one or more stops or kindred devices, whereby in its passage down the bed the form of metal is automatically turned or revolved.

5. la a tlux apparatus, in combination with carrying-rollers l), operated as described, the flux-applying brushes H, as and for the purpose specified.

ii. In combination with the hinged brushsnpports K. the flux'supplying tubes J, adapted to receive and contain flux and supply the same to brushes connected therewith.

In testimony whereof I have hereunto signed [00 my natne this 24th day of July, A. I). 1880.

HERMAN MILLER.
