JOHN G. REHFUSS AND MARTIN O. REHFUSS, OF PHILADELPHIA, PENN- SYLVANIA, ASSIGNORS TO THE BUREAU OAN AND MANUFACTURING COMPANY OF DELAWARE.

SPECIFICATION forming part of Letters Patent No. 754,702, dated March 15, 1004. Application filed August I, 1902. Renewed January 4, 1904:. Serial No. 187,741. (No model.)

To c1/,ZZ whom it may concern;

Beit known that we, JOHN G. REHFUss and MARTIN O. RnHrUss, citizens of the United States, residing at Philadelphia, in the county of -Philadelphia andv State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for FluXing Oans; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this'specication.

This invention relates to new and useful improvements in iuxing apparatus for use in connection with can-making machinesyand it consists in the provision of mechanism whereby the seams of a can may be thoroughly iiuXed while the can is either rotating or moving longitudinally, in the former case the fluXing apparatus being adapted to travel with the can as it rotates and when used for luxing longitudinal seams to remain station-A ratus is -adapted travel with the cans. Fig. 2

is a sectional View through the iuXing-receptacle and parts of the endless carrier` and means for holding and rotating the cans thereon as they travel in contact with the i'luXing apparatus. Fig. 3 is a perspective view of the iuXing-wheels, showing the relative arrangement of the same whereby the flux is fed from a receptacle by frictional contact with the wheels to a can. Fig. 4 is a side elevation of our iiuXing apparatus shown as held stationary and as applied to a portion of our can-making machine Serial No. 104,870. Fig. 5 is a top plan view of a modified form of .fluXing-boX.

Reference now being had to the details of the drawings by letter, A A designate parallel portions of the frame of our machine for soldering the tops and bottoms to cans as covered by our application hereinbefore referred to and to which we have applied our luXing mechanism. Said frame carries an endless carrier on which the cans B travel in upright positions while passing by the two horizontal portions ofthe frame. In the drawings, however, vwe have omitted all mechanism for actuating the cans, vas the same forms no part of the present invention. Mounted on a shait OI, journaled in a standard C', forming .a portion of the i'rame, is a lever D, having plication, as they form no part of the present invention; but said carriages are shown merely for the purpose of showing how the attachments for operating the iiuxing apparatus are operated. l

- The uxing mechanism comprises one or more receptacles F, which are adapted to contain iiuXing liquid, each of which is supported on a bracket-shapedmember F, having preferably dovetailed vconnection therewith, as illustrated, and by means of van adjustingscrew F2 said luXing-recepta'cle may be held .indifferent positions with relation to the bracket supporting the same. The ends of said bracket-arms are grooved, as at G and G, and each bracket-arm has a clamping-jaw H, also provided with two concaved portions, which are adapted to form in connection with the recessed bracket-arms clamping means to receive the gas and air pipes K and K, respectively, said clamping-jaw H being held to the bracket-arm F by means of bolts L.

Mounted in suitable bearings in the side walls of the receptacle is a shaft N, on which the crank-arms M are pivotally mounted, and journaled in said crank-arms M is a shaft O, on which a beveled linx-feeding friction-wheel P is mounted, which is in contact with the beveled portion of the wheel Q, which is mounted on the shaft N and is positioned in the 'luXingreceptacle. Adjustably held in an aperture or suitable bearing in the shaft O is a stubshaft R, which is held in an adjusted position by means of a set-screw r. Keyed to said stub-shaft R is a beveled ux-feeding wheel R', which is normally in contact with the beveled portion of the wheel P. Said crank-arms may be held in inclined positions by means of the screws T and T, which are right and left threaded and mounted in a similarly-threaded nut T2, whereby as said nut is turned in one direction or the other said screws may be turned out or in for the purpose of holding the arms in adjusted positions. It will be observed that said crank-arms may be raised or lowered accordingly as the can to be soldered travels at different elevations, and in either case the three wheels of the fluxing mechanism will be in contact with one another, thus insuring a continuous feed of the flux.

Referring to the modified form in Fig. 4, we have shown the uxing device held stationary instead of traveling with the cans which are to have their tops and bottoms luXed and soldered, the form shown in said modification being for Huxing longitudinal seams of cans which travel underneath the fluxing mechanism. In this modification two plates M are held together by means of a pin J, and the flux-feeding wheel Q has a doublebevel circumference instead of a single bevel, as in the other form of luxing mechanism, and mounted on a shaft O', carried at the ends of said plates M', is another wheel with double bevel (designated by letter R2) which has friction al Contact with a fiuX-feeding wheel P, which has a grooved circumference in which the two wheels Q and R2 have frictional contact. The wheel P is mounted on stub-shafts P3, which have bearings in the notches in said plates. In the modified form we have shown a screw T3 passing through a threaded lug on the flux-containing receptacle and having a head T2 provided for the purpose of raising or lowering said screw when it is desired to adjust the flux-feeding wheels with relation to the seams which are to be uXed. In Fig.

4 it will be seen that the flux-containing receptacle has dovetailed connection with the standard Q2 and may be held at any location thereon in order to secure proper adjustment;

In order to impart an accelerated movement to the oscillating lever when traveling in one direction, we provide a cam W, having a camgroove W2 in the face thereof, which cam, substantially heart-shaped, is mounted to rotate with the shaft C. A lever W' is pivoted at W3 to a standard supporting the shaft C and carries an antifriction-roller W", which is adapted to travel in said groove W2, and pivotally connecting said lever WV and the oscillating lever is a link W5. By this peculiar construction of cam and connections with the oscillating lever it will be observed that the fluxing devices (there being two shown on the upper portion of the machine and two on the lower portion for {iuxing the tops and bottoms of cans) will be given a variable reciprocating movement through the rod D2, which connects the pivotal pin E with the bracket F, which is fastened to and is adapted to reciprocate with the pipes K and K', through which pipes air and gas are conveyed to burners for heating the can, but which are not illustrated, as they do not form any part of the present application.

The vmeans for rotating the cans comprises a spring-actuated plate or disk V, which has a shank portion mounted in one of the links V of the chain of the endless carrier and which shank portion has keyed thereto a pinion V2, which is in mesh with the teeth of a gear V3, also carried by a link of the carrier and in mesh with a rack-bar VX. The can is held between said rotary disk and a stationary swiveled disk V4, which rotates with the disk as it travels with the carrier and during the fiuxing process.

The operation of our improved Huxing apparatus when used in connection with the construction illustrated in Fig. 1 of the drawings, in which the rotating cans are iuxed, it being understood that the cans are mounted on an endless carrier, only a portion of which, however, is illustrated, as said cans are traveling along the horizontal portions of the frame illustrated, the cans are rotated in any suitable'manner, (not illustrated,) and adjacent to the path of the rotating cans are located the fluXing devices, and as the linx-feeding wheel R comes in contact with a can adjacent to its connection with the top of the can, which in the upper portion of the carrier is inverted, said wheel R will be held yieldingly against the can, as illustrated in the detail View, and the rotary movement of the can will impart by frictional contact with said wheel R a movement to the latter, and ux will be fed from the receptacle by the bevel-wheel Q to the wheel P and thence to the wheel R', onto the seam to be soldered. As a can comes into contact with the lower beveled edge of the wheel R the latter will be raised slightly. In case there should be a little variation in the location of the plane in which the seam to IOO IOS

be soldered is positioned the wheel R and the wheels in contact therewith will rise or lower and still be in operative connection with one another. As the cans are traveling in the direction indicated .by the arrow, the fluxing will be accomplished while the iiuxingwheels are being driven forward by means of link connection with the oscillating lever D, said lever being driven by means of the heartshaped cam W, which is keyed'to rotate with the shaft C, said lever having pivotal link connections with a lever VV, carrying an antifriction-roller journaled in a groove in said cam. By reason of the peculiar shape of said heart-shaped cam it will be observed that an accelerated movement is given to said oscillating lever when not moving in the direction of the carrier, and having a slower movement while iiuxing a can than on the return movement of the oscillating lever, which carries the uxing devices back to come in contact with the following two cans. It will thusbe seen that the tops of two cans are fluxed simultaneously on the upper portion of the machine and the bottoms of two cans are iiuXed simultaneously with the tops on the lower .portion of the frame, it being understood that said oscillating lever actuates two sets offluX- ing apparatus of similar construction, but reversely arranged, one set being to iiuX the tops of the cans, while the other is provided for fiuxing the bottoms of the cans.

In the modification our iiuxing apparatus is positioned so that the wheel PJl will travel over or rest upon the longitudinal seam of the can as the same is fed forward on a former after having been turned into cylindrical form and after its edges are interlocked and clenched by mechanism which forms no part Vof the present'invention.l
