,BRUSH HOLDER FOR TINNING MACHINES.
Application filed September 19, 1921. Serial No. 501.679.
T 0 all whom it may concern:
Be it known that I, RUFUS E. ZIMMERMAN, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Brush llolder for Tinning Machines, of which the following is a specification.
This invention relates to apparatus for coating sheets and plates with molten metal, and more particularly to the wipers or brushes used to remove the molten metal from the coating or feed-out rolls of the apparatus, and has for its principal object the provision of an improved form of wiper or brush that will bear with uniform pressure against said rolls throughout its length.
Another object is to provide a novel adjustable holder for the wipers or brushes of such apparatus that will prevent the spreading or squashing of the brushes as they are drawn up against the rolls.
lVhile not limited to apparatus for coating with any specific metal or metals, this invention is particularly adapted to tin pots used in coating sheets and plates with tin, and is so illustrated and described.
A further object is to provide a coating apparatus of the novel design and combination of parts described in the following specification and illustrated in the accompanying drawings, in which:
Figure 1 is a transverse vertical sectional elevation of a tin pot having the invention applied thereto.
Figure 2 is a sectional elevation taken on the line 11-11 of Figure 1.
Figure 3 is a sectional plan on the line TIL-III of Figure 1.
Figure -t is an enlarged fragmentary sectional elevation of the tinning pot of Figure 1.
Figure 5 is a cross sectional elevation through one of the brushes.
Figure 6 is a View similar to Figure 5, of a slightly modified form of brush.
In the accompanying drawings, the numeral 2 designates a tinning pot of old and approved form. The pot is separated transversely by a vertical wall or partition 3 into compartments A and B. The lower edge of this wall 3, which terminates above the bottom of the pot and the upper edge of a rib or projection 4 on the bottom of the pot, de-
fines the width or vertical dimension of a 1 narrow passage or opening C through which plates pass from the compartment A to the compartment B.
The side walls of the compartment A at the exit end of the pot are extended upwardly, so that this compartment is considerably deeper than the other compartment B, this old and well-known construction enabling a body of oil, of the requisite depth or thickness, to be maintained on top of the molten tin in the compartment .A. The forward end of the plates being tinned are directed into the compartment A from compartment B and between guide plates 8 and 9 forming guide'N, which directs the forward end of the plates upwardly into the bite of the lower set of feed-out rolls 10 of two sets of feed- out rolls 10 and 11 within the upper end of the compartment A.
It will be noted that the rolls 10 and 11, guide plates 8 and 9, and other working.
parts of the pot are mounted on a frame Y, consisting of side plates 13 and 14 secured together in spaced relation by tie bars 15 and adjustably supported in the pot by hangers 17 and 18.
Each of the rolls in the sets of rolls 10 and 11 is provided with a wiper or brush 19 composed of a strip or strips of asbestos or other like flexible material. The strips forming the brush 1!) are secured together at its lower end by pins or rivets 20 and the brush is mounted in a Ushaped or slotted guide and supporting member 21 which extends the full length of the brush. A bar 22 is mounted in the slot of the member 21 under the brush 19, and is of less width than the slot in the member 21 so as to move freely therein. The bar 22 is provided with rounded projections 23 on its bottom face. which register with and extend through suitable openings 24 in the bottom of the member 21 for a purpose to be described.
The members 21 for guiding the brushes for the upper rolls are secured by angle brackets 26 to the side members 13 and 14. of frame Y. The brackets 26 are secured to the side members 13 and 14 by bolts 27 which pass through elongated apertures in the brackets 26 to permit horizontal adjustment thereof. Angle supports 25 are arranged under each end of the members 21 for the upper roll brushes and are secured brackets 26? are secured to. the members 21 by cap screws orstuds 27 and to the supports 25 by bolts 28. v
The sides 32 and 33 of the member 21 have-their-upper faces beveled away from the brush 19 as'at 34 andthe uppermost portion of said side portions extends within a fraction of an inch of the rolls and the top face of the brush, thus it will be seen that the brush is supported on each side and prevented from spreading or squashing as the brushes are drawn or forced up against the rolls to remove surplus metal therefrom.
The brushes 19 are adapted to be held under tension against the rolls by a plurality of levers 35 which have their rear ends pivoted between angle brackets 36 secured on transverse bars 37 extending between the side plates 13 and 14 and secured to the projecting flange of supports 25. The brackets 36 are arranged in pairs and the brackets for the levers which operate the brushes for the upper set of rolls extend upwardly from the upper face of the bars 37, while the brackets -for the levers which operate the brushes for the lower set of rolls extend downwardly from the lower face of the bars 37. The levers 35 extend through the cut away portions or openings 24 in the U- shaped members or guides 21 and their upper face adjacent the forward end forms a point contact with the rounded projections 23 on the bars 22 which are mounted under the brush. The levers 35 are pivotally connected intermediate their ends to the lower ends of vertically movable tension rods 39, which project through suitable apertures in transverse bars or beams 40 supported at each end on lugs 40 on the side plates 13 and 14. Suitable coiled springs 41 are mounted on the upper ends of the rods 39 above the bars 40 and held under tension. by washers or collars 42 which fit around the rods 39, abut the upper ends of the springs 41, and are adjustably held against the springs by nuts 43 threaded upon the ends of rods 39. The nuts 43 when screwed down will compress the springs 41 against the bars 40, thereby pulling the rods 39 upwardly, which,- due to their pivotal connection with cause their forward ends to bear against the cause thirforward ends to bear against the bars 22 in the guides 21 and force the brushes 19 against the rolls.
It will readily be seen that with the above construction the brushes 19 will have a substantially constant pressure or tension against the rolls 10 and 11 regardless of wear, and that this tension 'or pressure may readily be adjusted by screwing the nuts 43 toward or awayfrom the spring 41. It
.will also be apparent that brushes construct ed in accordance with this invention will have a longer life than the brushes heretofore constructed, since they are supported on both longitudinal sides so as to positively prevent them squashing or spreading, and due to the rigid bar 22 bearing against the ,bottom surface of the brushes 19 they have a more even bearing against the rolls than brushes as heretofore constructed.
I claim I a 1. In a machine for coating metal sheets with molten metal, the combination with a roll arranged to remove surplus metal from the sheets, of a rigid brush holder having a longitudinal recess therein for the reception of'a flexible brush, aflexible brush mounted in said recess and adapted to contact with said roll, and means for moving said brush relative to said holder.
2. In a tinning machine having a roll arranged to remove surplus molten metal from a sheet, a slotted brush holder rigidly mounted in said tinning machine adjacent said roll, a flexible brush mounted in the slot of said holder, a bar loosely mounted in the slot below said brush, a plurality of levers each having one end pivoted in said machine, and its other end engaging said bar, tension rods pivotally secured to said levers intermediate their ends, and springs under tension engaging the upper portion of said rods to normally pull said rods upwardly and rock said levers against said bar and force said brush against said roll.
3. In a tinning machine having a roll arranged to remove surplus molten metal from a sheet, a slotted brush holder and support rigidly mounted in said tinning machine below and in close proximity to said roll, a flexible brush mounted in the slot in said holder, and means for moving said brush relative to said holder to normally hold said brush in even contact with said roll.
4. In a machine for coating metal sheets with molten metal, the combination with a roll arranged to remove surplus metal from the sheets, of a slotted brush holder rigidly mounted in said machine adjacent said roll. a flexible brush mounted in the slot of said holder, a bar loosely mounted in'the slot below said brush, a plurality of levers each having one end pivoted in said machine and the other end engaging said bar, and s ring tensioned means for holding said evers against said bar so as to force said brush to bear uniformly against said roll.
