WILLIAMS, OF BRIDGEPORT, OHIO, ASSIGNOR TO EXTRUDED METAL PRODUCTS COMPANY, OF BRIDGEPORT, OHIO, A CORPORATION OF OHIO PICKLING CRATE Application filed February 4, 1929. Serial No. 337,179.

This invention relates to pickling crates, and pertains to crates of that character used for pickling metal sheets, packs, and the like.

As is understood in the art, pickling is effected by means of reciprocation of a crate containing the sheets or packs within a tank containing the pickling fluid, and the present invention has for its primary object to provide a crate having improved means for supporting or holding the sheets or packs rigidly and in substantially perfect alinement.

A further object of the invention is to provide improved means for securing the various sets of pins, between which the sheets or packs are introduced, in rigid and substantially perfeet alinement.

A further object of the invention is to provide a division wall between adjacent rows of pins so as to prevent the sheets or packs from being deflected by engagement with such pins so as to project into adjacent compartments.

A still further object is to provide in a crate of the character mentioned novel partitioning means or division walls and improved means for supporting the sheets or packs from their bottoms in the crate.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which Figure 1 is an end elevation of the invention;

Figure 2 is a side elevation, partly in section;

Figure 3 is a top plan view; I

Figure 4 is a detail side elevation of one of the division walls or partitions; and- Figures 5 and 6 are sections on lines 55 and 6-6, respectively, of Figure 4.

Referring to said drawings, the reference character 1 designates a base 1 of substantially grid form, preferably made of bronze which will not be deteriorated by the acid of the pickling bath. The base or grid 1 has spaced parallel bars 2 throughout its width, which latter are formed with tapered openings 3 in which are received correspondingly taperedlower ends 4 of a series of pins or posts 5, said pins being rigidly held in such position by heading or peining the lower ends of the posts or pins, as shown at 7.

As shown in the drawings, the portions of the bars 2 which have the tapered openings 3 therein are enlarged, as shown at 8, so as to strengthen the bars and to compensate for the loss of material due to the formation of the holes 3. As clearly shown in Fig. 3 of the drawings, there are thus provided a series of rows of posts or pins which extend vertically and which are spaced both longitudinally and laterally of the grid. The four corners of the grid have lifting posts 9 attached thereto, the means of attachment being preferably as explained in connection with the securing of the posts 5.

The upper ends of the lifting posts 9 are connected by a substantially X-shaped frame 10, the latter having a series of loops or eyes 11 projecting upwardly therefrom and formed to be engaged by the supporting hooks of a lifting crane or other suitable mechanism by means'of which vertical reciprocatory movement is imparted to the crate. v

The frame 10 has integral end connecting bars 12 and adjacent to one of the latter a transverse connecting bar 18, the latter and the adjacent bar being formed with apertured lugs 15 and 14, respectively", to receive therein a rod 16 which latter projects outwardly from the adjacent end of the crate and which functions as a guide rod for vertical sliding movements in spaced parallel guides (not shown) located on the pickling fluid tank for prevent- 85 ing rocking or swaying of the crate while in the pickling bath.

For the purpose of holding the inner end edges of the sheets or packs against movement inwardly of the crate, horizontal end bars 17 are provided which are formed with spaced openings 18. The openings receive the downturned ends 18 of stop rods 19 therein, there preferably being provided a pair of these stop rods, as shown in Fig. 3. The bars 17 are supported in position on the upper ends of posts 20, the latter being secured to the outer ends of the base 1 in a manner described in connection with the securing of the pins 5. It will thus be seen that the rods 19 can be adjusted to accommodate sheets or packs of different lengths or sizes so as to support same within the crate.

In order to prevent the sheets or packs from moving out of the crate, closing bars 21 are provided which are carried by supporting posts 22 that are secured to the four corners of the base, preferably in a manner described in connection with the securing of said pins 5. The closing bars may be made of round bars which have their ends bent to form a series of convolutions 21, thereby providing eyes which are received over the posts 22. The eyes 21 of the closing bars 21 rest in seated position above the base on washers 23 mounted on shoulders 28 provided on said posts 22.

As clearly shown in Figs. 4, 5 and 6, the crate is preferably divided into a plurality of compartments by means of sheet metal walls or partition plates 24, which latter extend longitudinally of the crate and are carried by the posts 5, the plates or walls 24 having struck out eyes or loops 25 which alternately project outwardly on opposite sides of the plates and which are formed to receive the posts 5 therein. Vith this construction it will be seen that the plates can be connected to the posts by vertically moving them thereover. The outer ends of the plates are formed with continuous knuckles or eyes 26, as shown in Fig. 4, while the intermediate eyes 25 of the plates project alternately on opposite sides of the latter.

As shown in Fig. 1 of the drawings, the partitions are formed of three vertical sections of the walls 24, the bottom wall or sheet resting upon the base 1 and being of such width that their upper side edges underlie the stop rods 19. The upper of the sections 24: is superimposed on the intermediate section 24. In order to maintain space between the lowermost section 2% and the intermediate section 24 to receive the stop rods 19, spacing sleeves 27 are mounted on the rods, as shown in Fig. 2, and seat on the lowermost sections 24 and support the bottom edge of the intermediate sections.

In operation it will be understood that the stop rods can be adjusted as desired and the inner ends of the sheets or packs are engaged therewith at their said end edges, the sheets being disposed in the compartments provided by and between adjacent walls or partitions 24 and are held against outward movement by the closing bars 21.

From the foregoing, it will be seen that there are no threaded parts whatever pres-.

ent in that portion of the crate which is eX- posed to the action of the acid in the pickling bath.

lVhat is claimed is- 1. In a pickling crate, a grid-like base having rows of apertures, posts having tapered ends in said apertures headed into engagement with the base, spaced opposite side bars carried by the base and spaced thereabove and formed with a series of spaced apertures, stop bars for engaging one end of the sheets or packs having downturned ends selectively engageable in said apertures oi the side bars, posts at the corners of the base, opposite closing bars connected at their ends to adjacent posts for engaging the opposite ends of the sheets or packs, and partitions for dividing the base into compartments having integral struck-out loops receiving the first named posts therein.

In a pickling crate, a grid-like base having rows of apertures, posts having tapered ends in said apertures headed into engagement with the base, means to engage the edges of the sheets or packs to hold same from movement outwardly of the base, and partitions for dividing the base into compartments having struck-out loops receiving the posts therein.

3. In a pickling crate, a base, a series of posts on the base each having a tapered end received in an aperture provided therefor in the base and headed into engagement there with, sheet separating elements secured to certain of the posts, spacing sleeves on the posts for spacing said elements, closing bars for the sheets, means to support the closing bars from the base, end bars having apertures, means to support the end bars from the base, and stop bars for engaging the sheets extending through the space between said separating elements and having parts received in said apertures of the end bars. 7

6. In a pickling crate, a base,a series of posts on the base, upper and lower partitions having parts receiving the posts therein, means to hold said upper and lower partitions in spaced relation, stop bars for engaging the inner end edges of the sheets disposed in the space between said partitions, and means for supporting the stop barsin position.
