Patented Dec. 19, 1933 PIPE STORAGE APPARATUS Edward W. Burgess; Milwaukee, Wis., assignor to A. 0. Smith Corporation, Milwaukee, Wis., a corporation of New York Application August 24, 1931. Serial No. 559,107 4 Claims. (cram-s) This invention relates generally to material storage systems and particularlyto a system for storing pipe in large quantities.

An object of the invention is to provide a 5 storage system for storing material in large quantities so arrangedthat a number of units of the material may be readily placed in storage ,or quickly removed therefrom.

Another object of the invention is tov provide a storage crate especially adapted for storing pipe in car load lots.

In accordance with the present invention, a storage system is provided for receiving in car load lots a large quantity of pipe of relatively large diameter. The pipe is piled in crates, each crate containing one car load of pipe, and the crates are adapted to be stacked one upon another on suitable foundations in the storage yard. The storage yard is. served" by a large crane having a lifting cradle designed to be engaged with the storage crates by the crane operator without the assistance of other workmen.

In a particular embodiment of the invention, when filled to capacity with pipe ten inches in diameter, the yard contains suificient pipe to construct a pipe line approximately 450 miles in length, the cratesof pipe being so arranged that the entire quantity of pipe may be removed from the yard in something. less than eight days.

The objects of the invention that have been set forth and other objects that will be appreciated on further consideration of this specification in conjunction with the accompanying drawings, may be achieved by the apparatus shown in the different views thereof of which:

, Figure 1 is a view in perspective of a mate-- rial storage crate embodying the invention disposed on suitable foundations and a lifting cradle suspended above it; Fig. 2 is a general view in end elevation of the storage system embodying the invention;

Fig. 6 is a view in horizontal section of the top of the post taken on the plane represented by the line 6-6 of Fig. 5 with the lifting hook represented in dotted lines. a

As shown in Fig. 2, the storage system embodying the invention comprises, in general, a relatively large craneway 1 upon which a transfer or bridge crane 2 of the usual construction is disposed to operate. From the crane 2 is suspended a carrier or cradle 3 adapted to engage and lift a crate 4 that is of sufiicient size to holdone car load of pipe 5 to be stored.

The crates 4 containing the pipe 5 may be brought to the storage yard on special fiat cars 6 that operate on a standard track "7 extending along one edge of the storage yard. From the cars 6.the crates of pipe may belifted by the crane and disposed upon suitable foundation blocks 8 Within the yard or upon other similar crates already in position in the yard. As shown in Fig. 2, the foundation blocks 8 are spaced laterally of the craneway 1 in such manner that the crates 4 may be placed relatively close together over the width of the yard and it will be readily understood that the foundation blocks 8 are spaced longitudinally of the yard with regard to the length of pipe to bestored in such manner that the available space is used efficiently.

As shown in greater detail in Fig. 1, each of the foundation blocks 8 isprovided with a load receiving shoe 9 having one or more upwardly projecting points or lugslO, the surfaces of which are disposed to engage complementary recesses 11 in the under surfaces of the crates 4.

Each crate 4 comprises essentially four corner posts 12, in the lower ends of which the recesses 11 are formed, as shown in detail in Fig. 3. At their tops, the posts 12 are providedwith projecting post caps or lugs 13 similar to the lugs 10 on the foundations 8 and spaced to enter the recesses 11 of another crate in such manner that crates may be stacked one upon another.

The two corner posts at each end of the crate are connected near their lower ends by a trans verse member 14 upon which the load of pipe in the crate is supported. The transverse member 14 is preferably made from a structural element such as an I- or H-beam and is joined at its ends to the posts 12, which are likewise of I- or H-section, by welded joints. The joints are reenforced at each side by suitable. gusset plates 15 that are welded to the edges of the flanges of both the cross member 14 and the p ts 12.

Beneath the gusset plates 15 at each corner of the crate 4 the post 12 is provided with side plates 16 welded to the edges of the flanges and extending, as shown in Fig. 3, substantially to the bottom of the post. The side plates 16, together with the flanges of the post 12, constitute the recess 11 in the lower end of the post. As shown in Figs. 3 and 4, the web of the post 12 is cut away to conform substantially to the contour of the lugs 10 and 13. The ends of the flanges of the posts 12 are machined to provide flat surfaces at right angles to the axes of the posts to provide complementary seating surfaces adapted to be engaged when the crates are stacked one upon another.

The pairs of posts 12 at the ends of the crate and their respective connecting cross members 14 are joined by relatively light longitudinal members 17 of angle iron welded in place and the structure is braced diagonally by other angle members 18 joined by welding to the longitudinal members 1'7. The posts at each side of the crate may be furtherbraced by'suitable longitudinal members 19 connected preferably by welding to the posts near their upper ends.

To enable the carrier or cradle 3 of the crane 2 to engage the crate 4, each post 12 is provided at its upper end with a hook receiving lifting opening 20 formed by piercing the web of the post 12. For engaging the lifting opening 20, the carrier or cradle 3 is provided with four depending hooks 21 that are pivotally connected to longitudinal members 22. The longitudinal members 22 of the cradle 3 are connected by suitable transverse members 23 which are engaged by four lifting cables 24 that suspend the cradle 3 from the crane 2 in such manner that the longitudinal members 22 are held'in parallel relation to the longitudinal members 17 and 19 of the crates 4.

With the cradle 3 thus suspended in longitudinal alignment with the crates 4, the hooks 21 may be readily engaged in the openings 20 by simply lowering the hooks to the level of the openings 20 and moving them into the openings 20 by longitudinal movement of the crane bridge 2 and the cradle 3. The crate 4 and its load may then be lifted and placed in position either on foundation blocks 8 or upon the top of another crate, the cradle 3 and the attached crate 4 being held in longitudinal alignment by the four lifting cables 24. After the crate has been placed in position, the hooks 21 may be readily disengaged by the crane operator without assistance by simply lowering the cradle slightly and moving it longitudinally to withdraw the hooks from the openings 20. To prevent the hooks 21 from slipping through the openings 20 when the cradle 3 is lowered, each hook provided with 3. depending lug 25 that is adapted to engage the web of the post 12, as shown in Fig. 5.

In lifting a crate of pipe, for example from the car 6 shown in Fig. 2, the cradle 3 is lowered with the hooks 21 at each side thereof on opposite sides of the load of pipe 5. Thus the pipe 5 is utilized to some extent to guide the hooks 21 toward the openings 20 in the crate 4. To further guide the hooks 21, each opening 20 is flanked by angularly disposed guide plates 26 welded to the flange and web of the post, as best shown in the sectional view of Fig. 6. After the hooks 21 have been guided into the openings 20, they are moved upward into engagement with the edge of the web of the post 12 that defines the upper end of the opening 20. As shown in Fig. 5, the web is reenforced at this point by reenforcing blocks 27 welded to each side thereof to provide a wide bearing surface for the hook 21. The post cap 13 is preferably of cast steel and is securely welded to the upper end of the post, thus further reenforcing it.

Although there is shown and described only one embodiment of the invention, various modifications may be made in the details of construction of the lifting crane and the storage crates without departing from the spirit and scope of this invention as defined in the appended claims.
