This invention relates to pickling apparatus and more particularly to an apparatus for-use, in the lckling of coilsof wire and thelike.

6 The primary object of the invention is to provide an apparatus for efiecting thorough and expeditious pickling of the wire, and more specifically'to impart a bodily movement to the coils of wire ina curved path in the pickling fluid.

A further object of the invention is to provide a pickling apparatus in which means is provided for opemngor spreading the convolutions or coils of the wire during the path, thereby to expose the entire circumferfines of the wire to the action of the pickling In describing the invention in detail, referonce is herein had to the accompanying drawings, in which- Fig. 1 is a top plan view of the invention;

gig. 2 is a sectlon on the line 22, Fig. 1; an

Fig. 3 is a section on the line 33, Fig. 2.

As shown in the drawings, a pair .of tanks 1 are employed for containing the pickling fluid, said tanks being mounted in side by side and parallel relation. A pair of'supporting columns 2 are disposed in spaced re ation to one of the ends of the tanks 1, while a similar pair of spaced supporting columns 3 are 10- cated ad acent to the opposite ends of the tanks 1. The columns 2 are connected by a horizontal girder 4 and a similar-horizontal grider 5 connects the columns 3. Upper and lower spaced bearings 6 and 7 are connected to the girders 4 and'5 and have upper and lower horizontal shafts 9 and 8 respectively jourend thereof while a similar se ental gear 9 is rigidly secured to each sha 9, and with the teeth of the two rs intermeshing, .by means of which itwill noted that the-shafts depending arm 8 rigidly secure bodily movement of the coils in a curved.

The wire coil carrie'ris composed naled' therein. Bearings 13 and 14 have the,

be rotated in opposite directions. The shaft 8, which is to the left in F' 2 has a thereon. A long link 10 is pivoted. to the lower end of the arm 8" and has its opposite end connected to an eccentric 12 which is mounted on a drive shaft 12. The other shaft 8 has a similar depending arm 8 aflixed thereto, while a short link 11 is pivoted to the lower end of the arm 8 and is connected to an eccentric 12 also 00 mounted on the drive shaft 12. The shaft 12 may be driven in any'suitable manner, as, by means of a motor M which is suitably connected thereto as shown in Figs. 1 and 2.

The crank shaft is mounted on a suitable base 12 which latter also serves as a support for the motor M. 7

As shown in Figsd l and 2 of the drawings the shafts 8 have; horizontally dispose radial lifting arms 15 connectel thereto, while the upper shafts '9 have corresponding lifting arms 16 afiixed thereto. It may be here stated that as many tanks as desired may be employed, and accordingly the shafts 8 and 9 are equipped with upper and lower pairs of 76 lifting ar so as to provide a pair of such arms at ea h end of each tank. The lower lifting arms 15'have vertically disposed yokes 17 secured to their outer ends, the outer or free ends of the yokes being pivoted to the 80 furcations of the arms 15. The arms 15 and 16 are disposed. direct! over the pickling tanks and confront eac other and have a wire coil' carrier or holder secured thereto.

of a horizontal bar 18 the ends of which rest in and on the closed bottomsof the yokes 17 as shown in'Fig. 3. The bar 18 is provided adjacent its ends with depending members 19 wardly to the left of is then moved to a wire coils C. Preferably, theupper face of the member 21 is of undulating formation so as to provide seats to receive the inner circumferences of the wire coils to thereby hold the latter against shifting longitudinally of the member 21, an eye or loop 25 being secured to each of the bars 18.

Vertically extending rods 23 are pivoted at 23 to the bifurcated outer or free ends of the arms 16, as shown in Fig. 3. The lower ends of the rods 23 project within the tanks 1 and are secured to cradles 24 which latter are disposed within the tanks. As shown in Figs. 1 and 3 of the drawings, the cradles 24 are offset or are disposed to one side of the members 21.

It will be noted that the cradles are provided withlongitudinally extending bars 24 which latter are disposed in spaced relation and'in the formation of a curve the latter corresponding generally to the curvature of the wire coils.

Referring to Fig. 2 of the drawings, it will be seen that in order to load the carrier, the latter being-disconnected from the apparatus, the free end of the bar-like member 7 21 is raised and the-member 19-swung out- Fig, 2, which enables the coils C to he moved onto the bar '21. After the coils have been positioned upon the bar'21, the latter and the memberlglt) are whereupon a lifting crane is connected to the-carrier by means of the eye 25 thereof and position to lower the carrier so that the bar, 18 of the latter is engagedin the yokes 17. Power is then applied through the motor M, causing the shafts 8 and 9 to oscillate. in opposite directions,

the medium of the-intermeshing segmental through and 9, thus causing the arms 15,

gears-8 17 and the wire carrier to move the yok downwardly as the arms 16 andthe rods 23 together .with rods move upwardly.

' From the foregomg', it will be noted that the wire coils an'd the cradle'are' caused to reciprocate or move toward and away from each T other and-as they move toward one-another, it
