FLUXING AND CLEANING APPARATS.

Application filed January 28, 1922. Serial No. 532,484.

This invention relates to a fluxing and cleaning apparatus for use with metal coating machines, such as are-employed for preparing sheet metal band or ribbon stock of copper or brass in the manufacture of automobile and other radiator tubes. p

The main object of my invention is to provide a novel apparatus by which the metal stock may be continuously cleaned and fluXed as it passes through the 'apparatus on its way to the metal coating and chilling devices of the entire machine, and thus permit thev rapid making of the tubes by a continuous and` uninterrupted process.

The invention consists further in the matters hereinafter described and claimed.

In the accompanying drawings z- Fig. 1 is a vertical longitudinal.sectionalview throughjthe apparatus ofmy invention.

Fig. 2 is a top plan view of the Same, and

Figs. 3 and 4-are vertical sectional views taken on lines 3-3 and 4,4, respectively, of Fig. 1. l

As shown in the drawings, the sheet metal band or ribbon 4 is su plied to lhe apparatus 1 in coil or roll fldrm- 5 which is supported by an upright bracket Gat the entrance end of thefdevice.

The apparatus 1 has an upwardly opening tank 7 supported abo-ve the-Hoor or other underlying surface by a bench like frame, comprising horizontal side members 8, 8 and vertlcal end members or legs 9, 9. Fixed in the tank 7 is a block 10. This extends lengthwise of the tank and has its sides short of the side walls of the tank, as shown in Fig. 3. Said block 10 is provided between its ends with a de ression or concave recess 11, and the upper ace of the block including this recess is shod or covered with a layer' of fabric 12, as shown.

Arranged above the fixed block 10 is a movable block 13. This has a depending rounded portion14, curved complementary to the recess 11 and designed to substantially t in'the same. Said curved portion 14 has its lower face shod or lined with a layer of fabric 15 which also follows the contour of the fabric 12 beyond the curved portion 14 and there is bent upward and secured about a cleat 16 carried by said block 13, as shown.

Said blockv 13 is raised vertically above and away from the block 10 by a vertical rod 17 extending upward above the tank 7 at kone side of the same and guided by a strap 18 fixed to thel machine, as shown in Figs. 2 and 3. The upper end of said rod 17 is curved inward over the tank 7 and downward to a fiat horizontal bar 19. This is secured to the block 13 and extends beyond the same, as shown in Figs. 1 and 2. The rod 17 is moved upward to separate the blocks 10 and 13 by a depressible foot pedal 2O below the machine, `as shown. When the block 13 is raised out of the tank 7, the blocks 10 and 13 are separated and themetal band or ribbon 4-from the roll 5 may be action to which the band is subjected re` moves all grease and verdigris therefrom and all foreign substance deposited thereon and insures a thorough fluxing and cleaning of t-he ribbon, preparatory to coating with metal.

-On leaving the block 13, the metal ribbon or band 4 passes over a fabric pad or wiper 21 on the lower `block 10. From this, Ithe ribbon-en ages aplurality of fabric pads or wipers 22,g23, 24, and 25, al1 arranged in the tank 7 beyond the blocks orpads 10 and 13 in the directionl of' travel of the metal band or ribbon 4. The second pad 23 is arranged between the first and third ones 22 and 24, and thelast pad 25 is beyond the third, as shown in Fig. l1. The first and third ads 22 and 24' are carried by the bar 19 an en- 'gage the upper surface of the metal band and are secured to and between cross bars 26.

on the tank 7, as shown in Fig. 2. .These pads or wipers 22 to 25 are above the level of the liquid or solution in the tank 7 and,

, not only remove the surplus lux, but all foreign substance and sediment gathered, and assure a thorough and positive distribution of the flux through the wiping motion` formed by the travel of the ribbon 4. To guide the ribbon 4 into engagement with said pads 22 to 25, there are laterally spaced guide rods 27, 27 carried by and depending from said bar 19 in advance of the pad 22 as shown in Figs. 1 and 4. On entering and leaving the tank 7, the ribbon 4 passes over rollers at the `ends of the same, as shown.

/The feed on the ribbon 4 in the tube mill (not shown) with which the fluxing and apparatus 1 is employed, draws the ribbon bet tween the blocks and across the Wipers in the apparatus 1 in accordance with the feed in the mill. From the apparatus 1, the ribbon passes through the metal coating apparatus which coats one or both sides ofthe ribbon with molten metal, such as solder, as

" required. The metal coating apparatus `is disclosed and claimed in my patentv No. 1,608,855, granted Nov. 30, 1926. From the coating device the ribbon 4 passes through a chilling apparatus (not shown) to harden the coated ribbonjust prior to entry into the 1. A flux applying machine, comprising atank adapted to contain a f luxing solution, two blocks arranged one above the other, one

y of, said blocks being fixed in said tank and submerged in the solution therein, the other block being movable toward and from said {ixed block, said blocks having fabric 1in- .surfaces to engage and clean both si ings on their opposed surfaces to engage and 'clean both side's'of the sheet metal band or ribbon drawn between them, and u right wipers' above the solution in said tan and across which the band passes after leaving said blocks.

wardly opening concave recess between itsl ends, said movable block having a depending rounded portion to fit in said recess, sai blocks having fabric linings on their opiposed e's'of the lsheet metal band or ribbon drawn between them, 4and wipers above the liquid in said tank and across which the band passes after leaving said blocks.

3. A flux applying machine, comprising a tankadap'ted to contain a fluxing solution, two blocks arranged one above the other, one of said blocks being fixed in said tank and submerged in the solution therein, the other block being movable `toward and from said iixed block, said blocks having fabriclinings on their opposed surfaces to engage land clean both sides of the sheet metal band or ribbon drawn between them, and 4wipers above the solution in `said tank and across` which the band passes after leaving said blocks, certain of said wipers being carried by said movable block and others fixed in said tank.

. In testimony that I claim the fore oing as myv invention, I aiix my signature t is 24th 80 day of January,

JOSEPH D. HARRIS.
