To all 1072 0122, itvntty concern:

Be it known thatI, OLIN S. FELLOWS, a citi' zen of the United States, residing at Middletown, Orange county, and State of New York, have invented certain new and useful Improvements in Means for Removing Superfluous Solder-from Sheet-Metal Cans, of which the following is a specification, sufficient to.

enable others skilled in the art to which the invention appertains to make and use the same.

Hyimprovements relate to machines for removing superfluous solder from the exterior of tin cans; and the invention consists, essen tially, in the construction and arrangement of parts hereinafter described and claimed specifically.

A distinguishing feature of my present construction consists in the use of a convex guiding-surface for the cans, in conjunction with an opposed flexible can-forwarding surface, whereby the cans are positively brought into engagement with the flexible forward ing-surface, subjected to a uniform degree of pressure, and properly spaced for presentation to the solder-removing mechanism. I thus not only prevent bunching, (the contact of one can with another,) but also sustain the cans more firmly in position against the resistance afforded by the solder-removing mechanism, at the same time compensating for any slight variation from the standard in the diameter or configuration of the cans individually.

Another feature of my present construction consists in so arranging the parts that the machine is practically reversiblethat isto say, the cans may be fed in at either end, as desired, according to the direction of motion imparted to the can-forwarding belt.

In the accompanying drawings, Figure l is a front elevation of the machine; Fig. 2, a sectional detail, upon an enlargedscale, showing the duplex blast-nozzle;-Fig. 3, a plan of the machine.

vex can-guiding surface is provided. Figs. 5, 6, and 7are respectively a top view, front and side elevations, of one of the standards supporting the convex can-guiding surface and top rail. Fig. 8 is a rear elevation of the machine. Fig. 9 is a plan of the machine with the covers removed; F- 10, an eleva- Fig. his a detail view of. one of the spring-jaws with which the con-.

'tion of the left-hand end of the machine; Fi 11, a vertical section on line 11 11, Fig. 3; Fig. 12, a vertical longitudinal section on plane of line 12 12, Fig. 3; Fig. 13, asectional elevation, upon an enlarged scale, upon plane of line 13 13, Fig. 3. Figs. 14: and 15 are respectively top and side views of the ad-v justable standard shown in Fig. 13; Fig. 16, a longitudinal sectional elevation on plane of line 16 16, Fig. 3; Fig. 17, a sectional elevation of the retarding-wheel, showing means for adjusting the same.

In the arrangement of parts shown in the drawings the convex guiding-surface E diverges from the center in both directions with relation to the opposed surface of the forwarder D, so that the cans may be fed in at either end of the machine. I do not confine myself, however, to this construction, the essential feature ofmy invention in this respect consisting in the use of a convex guiding-surface opposed to a flexible can-forwarding surface for presenting cans to the action of solder-removing devices when the convex guiding-surface is so arranged with relation to such solder-removing devices and to the flexible can'forwarding surface that the cans are successively and positively forced against the flexible can-forwardin g surface by the convex guiding-surface, so as to insure effective contact therewith for the purpose of spacing the cans with relation to each other and sus taining them more effectually while subjected to the action of the solder-removing devices. In other words, 1 contract the space between the stationary can-guiding surface and the flexible can-forwarding surface to less than the diameter of the cans to be treated, and 1 hence cause them to bend ordefiect said flexible can-forwarding surface, even though the cans may vary slightly in shape or diameter as compared one with another. I thus obviate a difficulty heretofore encountered in the use of straight can-guiding surfaces parallel to the forwarding-sorface, in which construction the cans are apt to collect or bunch in contact with each other by reason of the retarding tendency of the brushing mechanism or lack of accuracy in the size or shape of the cans under treatment. Thus by the substitution of the convex can-guiding surface in lieu of the straight parallel guide heretofore used I insure positive contact for each and every can introduced between the flexible forwarding-surface and the said guidingsu'rface, and in order to enable the flexible forwarding-belt to adapt itself to any number of cans interposed between it and the convex guiding-surface it shall exert a uniform pressure on each and every can. I hold the forwarding-belt taut by means of an automatic tension device F of any suitable construction, that shown in the drawings consisting of an idler-pulley e, mounted in a yielding bearing 8, actuated by a Weight 6 or equivalent mechanical expedient which causes the idler-pulley e to take up any slack;

in the belt D, while yielding to allow the said belt to accommodate itself to the number of cans'introduced between it and the convexguiding-surfaceE. Thereceivingend of the convex guiding-surface E is formed with a spring-jaw e which projects eccentrically with relation to the forwarding beltpulley d at that end of the machine. Where the machine is made reversible or right and left handed, as shown in the drawings, both ends of the'convex guide E are thus furnished withspring-jaws e It will be seen that the brushing mechanism is situated centrally in the apparatus with a fluid-blast O O at eitherend, so that the end plate of the can is first subjected to a fluid-blast. Then the cylindrical edge of the can is brushed, and, finally, the end plate is again subjected to a fluid-blast. sult the superfluous solder is first blown from the end plate, aportion of the solder being carried onto the extreme edge of the can and Keven beyond-theapex of the angle and onto the cylindrical flange of the end plate, from which it is mainlydislodged by the brush, which latter, however, is apt to leave a slight bur or ridge of solder on said apex, to 'be removed by the final fluid-blast, which cleans and polishes the angle of the plate.

In order to insure this latter result, I use for the second fluid-blast a duplex nozzle G, (shown in detail in Fig.2,') the jet g being directed against the inner side of the end plate, while the jet g is directed against the angle of the flange thereof, insuring the displacement-of all solder from the end of'the can. r

The cans are retarded'an'd rotated while subjected to the fluid-blasts by wheels H H, which are mounted in sliding bearings 71 It, so that they maybe adjusted with relation to the convex guiding-surface for the purpose of increasing or diminishing thetime during which each can is submitted to the blast; the protrusion of the periphery of the retardingwlieel beyond said convex-surface governing the surface tobesurmounted and traversed -by the can before its release from' the'retarding-wheel.

The sections 13 B" are mounted'upon the shaft I), supported in end bearings b b and .an intermediate bearing b ,-which steadies As a reand centralizes the shaft against lateral strain during use. The said shaft is actuated by spiral gearing in the manner described in my concurrent application, Serial No. 127,643, filed October 17, 1902. The sections of brush are inclosed when in use by covers a a, hinged to the main cover a, which closes the compartment a within the base A.

The convex guiding-surface E is made adjustable with relation to the brushes and to the forwarding-surface D for the purpose of accurately defining the path of the cans by any suitable mechanical expedient, as by forming the bases 6 e of the supportingstandards 6 e with slots 6 e through which pass the adjusting-screws e 6 as shown in the drawings. The forwardingbelt D is also made adjustable with relation to the solderremoving mechanism and the convex surface for the purpose of adapting the apparatus to the treatment of cans of different diameters.

This is accomplished by making the bearings the slack of the driving-belt D.

N is the stationary bottom rail for the support of the cans, and M the 7 upper rail for confining the cans in position between the convex guiding-surface and the forwardingbelt. This upper rail Mis adjustable vertically upon its standards to accommodate cans of different'lengths, as by means of the slotted brackets m m and bolts m m. (Shown in Figs. 5, 6, and 7.)
