I METHOD FOR'SHIPPING METAL Original Filed Jan. 23, 1930 MWIIHHW N li nl Patented Mar. 15, 1932 UNITED STATES PATENT OFFICE ROBERT T. ROMINE, OP MOUNT CLEMENS, MICHIGAN, ASSIGNOR TO MATERIAL HANDLING, INC., WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE METHOD FOR SHIPPING METAL Original application filed January 23,1930, Serial No. 422,845. Divided and this application filed December 31, 1931. Serial No. 584,243.

ing the metal, such as sheet,'strip or bar steel,

on the floor of a freight car or carrier for transportation in relatively heavy units and in such manner as to prevent or resist such relative shifting movement of the constituent parts of the packs or bundles as would result in damage to the freight car, damage to the material, and render diflicult and expensive the removal or unloading of the metal at destination.

A further object of the invention is to provide a new and eflicient method, as well as an apparatus for carrying out the method, for shipping sheet, strip or bar metal in packs whereby resistance to the relative sliding or shifting movement of the parts of the pack during transit is obtained through the medium of friction material causing a binding or frictional action on the parts within the pack, or within the cross-sectional area 9 thereof.

In my issued Patent 1,7 45,057 granted J annary 28, 1930, and'more particularly in Figures 7 and 8 thereof, I disclose a method of shipping sheet metal in which the pack is divided into sub-units spaced vertically by interposed members of relatively softer material, such as wood.

The present invention is an improvement upon the method of the aforesaid patent. I have found that by suitably spacing the friction members, when the sheets or strips are arranged flatwise, and even when they are arranged edgewise, and causing the pack to become distorted so that portions thereof enter the areas at opposite sides of the spacing member or members, it is possible to increase the frictional engagement and more effectively resist relative movement of the constituent parts of the pack.

If several spacing members are employed,

ing shown in the present instance.

it is necessary that they be suitably spaced to permit the parts to enter the intervening space under their own weight or under external pressure which may be applied, for example, by suitable binding means'encircling the pack. It is not necessary, of course,

that several spacing members be utilized, since a single member dividing the pack into sub-units may be employed in such a way that the weight of the pack or pressure applied, at opposite sides thereof, will cause the sheets or strips to be deflected in such a way that the spacer will, by its frictional engagement with the sheets or strips, prevent movement of the constituent parts of the pack due to the distortion of the units at opposite sides of the spacing element or elements.

In the drawings:

Figure 1 is a side elevational view of a modified form.

Figure 2 is a vertical sectional view on substantially the line 22 of Figure 1.

Figure 3 is an end elevation showing still 7 another form.-

Figure 4 is a detail perspective, and

Figure 5 is a view similar to Figure 1, showing a single spacing member of slightly different form of that employed in Fig ure 1.

Referring to Figures 1 and 2, the stack is divided into a lower sub-unit O and an upper sub-unitO. These units are spaced by one or more wooden strips 10, 11 and 12,-as will be observed. The entire stack is mounted upon a skid or pallet consisting of Iongitudinal riding or skid members 13, two be- These skid members are preferably connectedby -means of'a series of transverse wood strips 14 forming spaces for receiving the lower wire binding elements hereinafter described.

The pack is guided in its shifting movement longitudinally of the car by means of guides 16 which are preferably nailed to the car floor.

The spacing means, such as strips 10, 11 and 12, one or more of which may be utilized, serve to divide the pack into vertically spaced sub-units, and provide areas which the subunits may be caused to enter, thereby increas- I if desired.

ing the friction engagements of the sheets with the spacing material.

Relative movement between the pack and pallet may be prevented in any suitable manner. Lower transverse members 17, which are secured to the pack may be utilized for this purpose, and may be arranged close to the transverse members of the pallet, if desired. Obviously, the pack may be tightened to the pallet by other means to prevent sliding or tilting movement. 7

Although the spacing members 10, 11 and 12 are of rectangular cross section, it will be understood that these members may be of any desired shape. For example, their surfaces ma 'be curved to prevent indentation or scratching of the sheets as they are distorted around the spacing members, as shown for example in Figure 5.

For insuring the proper distortion of the sheets, binding means utilizing the lower transverse members 17 may be employed. These transverse members cooperate with upper transverse members 17, and the same are tied together by means of ties 19, which may extend over plates 20 acting as hearing pieces between the wire and wood strips to prevent the wire from cutting into the latter. Before the ends of the wires are tied, the same may be drawn taut to deform or distort both the upper and lower groups 0 sheets, as shown in Figure -1.

I prefer to form the sub-units or sectionsv of such width or number of sheets and to so arrange the spacing members that the weight of the sheets will cause the same to sag or become deflected or distorted and thus assist the binding means.

Referring to Figures 3 and 4, the invention is shown as applied to a stack in which the sheets or strips are of uniform width and the stack is divided into three sub-units. The stack 5 comprises a lower section P, an intermediate section P, and a top section or sub-unit P". Ihe several sections or subunits are spaced, by transversely extending pieces 21 of relatively softer material. Only one, piece is shown in Figure 3, although it will be understood that a plurality of pieces are interposed at each horizontal line of division, as in Figures 1 and 2. Wire binders 22 extend across the pack between the subunits and connect wooden uprights 23 which are drawn tightly into engagement with the edges of thesheets by means of the binders so that the sheet edges remain embedded therein, both at the time the pack is bound and during transit. In this form, the weight of the several sub-units is utilized to cause distortion and sagging into the areas between the spacer members 21, although external pressure for this purpose maybe employed,

Referring to-Figure 5, the pack consists of a plurahty of units, in the present in-" stance two, designated, respectively, as R and R spaced vertically and separated by a spacer strip 24, which in function corresponds to the spacer strips illustrated in Figure 1. The strip 24:, however, is devoid of sharp corners or edges, and from its wide central portion tapers gradually on its opposite sides to relatively narrow edges 24. In this form, the spacing means is disposed at substantially the cent-er of the stack, and the two units are carried into the horizontal plane of the spacer means by a binder which oncircles the stack.

In this form of the invention, as in Figure 1, the binder makes use of lower horizontal strips 25, which are disposed adjacent the end transverse pieces of the pallet, the parts of which are designated by the same reference numerals as in Figures 1 and 2. As will be understood, these transverse strips 25 pre vent sliding movement of the stack relative to the pallet, and obviously the corresponding members in Figure 1 may be similarly located closely to the transverse pieces of the pallet; The encircling binding means in eludes upper transverse bars 26, and the upper and lower bars are drawn toward one another.

by means of ti'ewires 27 which overlie at the transverse pieces protecting clips 28 corresponding to the protecting clip shown in Figure l.

It will be understood that the tying means serves to distort the units into the plane of the element 24 at opposite sides of the latter, and thereby increase the frictional engagement of the sheetswith one another and with the spacer unit. This tying means may be applied to the stack either before the same is positioned upon the pallet or thereafter.

Obviously, the invention is not limited to details of construction described, and the method may be modified Without departing from the invention to the extent indicated by the following claims.
