HAL-LEE, 0F VJ'HEELING-pWES-tfi VIRGINIA, ASSIGNOR TO 1 WHEEIJNG BRONZEG S$TING-COMPANY, WK'HEELINGpWEST -VIRGINIA, lA CORPORATION OF WEST VIRGINIA v PICKLING-APPARATUS -FOR RO-DS, -T U-IBES, AND BARS Application filed August 28, waaseriai This-invention'relates'broadly to pickling apparatus,-and more particularly to an apparatus for pickling metal tubing, rod-s,-shaiting and like-slender orattenuated articles or strips.

The primary object-of the' inventionis to provide apparatus'o-f this-character which h'asnovelandimproved means for subjecting the entire surface of the articles to the action of the pickling fluid.

A further object of the invention is to provide a device of thecharacter mentioned in which the articles are given-a swinging movement laterally through the pickling fluid and, at the'same time, are caused torotate by alternate tipping of the ends of the cradle or carrier in which the articles are held.

A further object of the invention is to provide pickling apparatus for effectually loosening and removing scale from the inner walls of tubing.

A still further object of the invention is to provide apparatus of this character, wherein the material to be pickled may be easily and quickly loaded into and unloaded from the apparatus.

A still further object of the invention is to provide apparatus of the type mentioned which is of simple and economical construction and which embodies a minimum of parts that are compactly organized and which are effective for the ends in view.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which Fig. 1 is a top plan view of the invention; Fig. 2 is a side elevation; Fig. 3 is a cross sectional view, illustrating the movements of the arms, links and cradles, and showing thesame in full lines at one extreme of their movements and in dotted lines at the other limit of their movements; and Fig. 4 is a section on the line 4-4i, Fig. 1, showing the parts during the loading or unloading of the cradle.

In proceeding in accordance with the present invention, a pickling tank 1, conveniently of rectangular form, is provided and is supported on base members 1'. A series of standards 2 are disposed along each of the N6. 388,949. Renewed August 22', 1931.

' vantageously the bearings are-formed to provide ways 3 which receive the upper ends' of 'the-standards 2', and bol-ts 3" secure the bearings in place; A shaft-4 is ournaled in each of the SGIlGS'O-Zl' bearings and isheld thereby above the top of" the tank: Said shafts extend longitudinally of the tank and have radial arms 5 secured thereto; the-arms 5 =extendinginwardly toward one another.

Links 6 are-pivoted to the inner endssoisai c l arms and depend therefrom, their lower ends being I pivotal-1y connectedto' the -upwardly projectin g side 'members ofsubstantially U shaped slings 'or cradles 7, sai'd crad le's having theirbottoinsmouglienedor serratedj 'as-in'd'i cated at 8, for a purpose' 'latertobe described. At one-end of-the shafts 4, arms=-9 are se cured and depend therefrom"; the arms 9 b'e i'ng pivoted to driving links 1O',"w-hi'ch latter ini turn are'pivoted to a crank arm. or -'ee'ce'n'- tric- 11, the element 11 being mounted oIra shaft- I2wl1ich is driven through any suitable source of power;

In operationy the apparatus is disposedwith the cradles 7 in the position indicated in Fig-.- 4,- whereupon the rods, tubes,- or" other articles M are" placed in the cradles orsli ngs 7, power being then applied to'theshaft l2. B'y reterence to Fig. 3, it will be'seen that the cradles 7 will thereupon be given a move ment in which said cradlesare oscillatedor reciprocated laterally of the tank and at thesaine time, theends of the cradles will be alternately tipped, thus causing the material to gravitate 1 andhave forced rolling move ment, as distinguished l from-= body-"sliding thereoii withoutrolling. Thus, the matrial is swunglaterally through the fluicl or isbodilyreci-procated and, due1to thie -alternate tiltingr'of theien'ds of the carriers o'r"cradles=, a Ifloiziced rotatingmovement of the 'material is a Y i It will further be notedithat a'tank iof'minimuin Widthcan be employed since: therange of movement of the c'rad'les (laterally i'ofith'ea tank is -rel'ati vely,a'smal1a; a i 1 u.

It will be understood, of course, that the number of cradles employed can be varied.

' What is claimed is- V 1. In combination with a pickling tank, a series of columns on'each side of the tank, shafts rotatably supported by the columns and extending longitudinally of and adjacent to the sides of the tank, radial arms on the shafts extending inwardly in overlying relation to the tank, links pivoted to the inner ends of the arms and depending therefrom, substantially U-shaped cradles having their bottoms'roughened and the upper ends of their sides pivoted to the lower ends of the links, a crank arm disposed to aline with thespace centrally between the shafts, arms depending from the shafts, driving links pivoted to the crank arm and to, the lower ends of the depending arms of the shafts, and means to impart rotary movements to the crank arm. 7 2. In combination with a pickling tank, a series of columns on each side of the tank, shafts rotatably supported by the columns and extending longitudinally of and adjacent to the sides of the tank, radial arms on the shafts extending inwardly in overlying relation to the tank, links pivoted to the inner ends of the arms and depending therefrom, substantially U-shaped cradles having their bottoms roughened and the upper ends of their sides pivoted to the lower ends of the links, and means .to oscillate the shafts in unison whereby to impart a combined bodily reciprocating movement of the cradles laterally of the tank and alternatetilting of the endsof the cradles.

3..In combination with av pickling fluid containing tank, cradles in the tank to support the material to be pickled, and means to impart a combined bodily reciprocation of the cradles laterally of the tank and al.- ternate tilting of the ends of the cradles.

I 4 In combination with a pickling tank,

cradles in said tank to support the material to be pickled, and means to impart a combined bodily reciprocation of the cradles laterally of the tank and alternate tilting of theends of the cradles, the bottoms of said cradles being roughened.

5. In combination with a pickling tank, cradles in said tank to support the material to be pickled, meanswto'impart a combined bodily reciprocation of the cradles laterally of the tankand alternate tilting of the ends of the cradles, and means to cause rolling of the material upon tilting of the cradles.

V 6. In combination with a pickling fluid containing tank, material supporting means in the tank, andmeans to cause swinging of the supporting means and thereby of the material through the fluid and laterally of a the tank and simultaneous rotary shifting movement of the material.

7 In combination with a pickling fluid material supporting means in said tank, means to cause combined swinging'of the supporting means laterally of the tank and simultaneous alternate tiltingof the ends of the supporting means, and means to cause rolling of the'material.

10. In combination with a pickling tank, material supporting means in the tank, means for oscillating said supporting means laterally relative to the tank, and means to effect rolling of the material borne by the supporting means during the oscillating movements of the latter.

In testimony whereof, I affix my signature.
