10Cl8ims. (Cl. v2811-1319) This" invention relates to an improved method and means forl securing heavyv bodies against movement during shipment thereof, and has particular 'reference to the'prevention of motion of iron and steel sheets and'coils of steel, iron and during transit on or in trucks, trailers or 'railway cars.

In the shipping of coils of iron, steel, paper cylinders and alsosheet steel, considerable damage results from uncontrolled movement of such connection with the door or platform of the transporting vehicle. When a vehicle loaded with such heavy bodies starts orstops suddenly, the inertia of a ycoil or pile of sheets composing such a body is tremendous and prior attempts to keep the body .stationary while in transit have not heretofore been successful. v

. The principal reason for the continued failure to keep said heavy bodies from moving in transit is considered'to be largely attributable to the present manner in which it is attempted to block, brace or shore the bodies on the iloor`ofa car. MainlyJzhis blocking or shoring is applied to the lowerv portions of said bodies. Since most of the inertia forces of a coil or pile of sheets are manifested in the top thereof, any attempt, therefore, to block, brace or shore said bodies underneath or against the bottom of the same is largely ineifective in obtaining theilrm 'securing of said bodies to a car deck'for platform. Such bottom bracing or blocking is now a common practice, -so far as I am aware, in the shipment of bodiesof the type to provide an improved 'method and means for securing such bodies againstund'ue movement forces are the greatest, namely, around the upper during shipment by the employment of an improved fastening means so designed as to resist the fmass inertia of said bodies where the inertia regions'thereof. l .Y

`Another object of the invention isto lash. the bodies ydown by passing a 'cable or cables over the sidesl and'top thereof and i'ordrawing and maintaining said cables in a tat condition when operativelyv applied to said bodies. A further vobject resides in a'fastening of the character aforesaid wherein 'provision is made for permitting `limited yielding movement vof vthe lashed bodies in response to inertia forces set up by the starting and stopping of the vehicle on which the bodies are carriedo. but `wherein' such' yielding movement yis limited and provides means for absorbing shockbut withoutany loosening or uncontrolled movement of the bodies held down by the lashing cables.

For a further understanding of the invention.

reference is to be had to the following description and the accompanying drawing. wherein:

Fig. s is a detail side elevation disclosing the lashing mechanism as applied to the stack or pile of metal sheets undergoing transit; v Referring more particularly to the. drawing. the

numeral I designates thefdeck, floor-or platform of acargo transporting vehicle, such as a railway car, the bed`or floor of a motor truck or trailer, or other transporting vehicle. The kpresent inven` tion is particularly concerned with the provision of an improved system for holding against undue movement 4during transit on such vehicles, heavy bodies of which coils of sheet iron or steel are outstanding examples, such coils having been indicated by the' numeral! in the accompanying drawing.i The ftendency of 'such cylindrical bodies to-roll or shift from selected positions during shipment is quite obvious and, as stated, large -I damage claims are attributable to this Therefore, to prevent such movement'. I provide a. lashing mechanism which, as shown in Figs.' l.

and 2 particularly, comprises one or more wire rope. cables,.as indicated a't 3. tai-n of their ends securedasjat l to heavy coil These cables have cersprings 5 which, in turn, are suitably anchored as at' to the door lI of the transporting vehicle.

'-From the springs 5, the cables I' extend horizontally a hunted distance and .are passed around 'guides or pulleys 1, also secured as at l in connection with the oor l. The rolls of sheet steel of the type indicated at 2', have placed thereover an After passing varound the frame 9, as disclosed in Fig. 2, the lower end of each cable engages with a guide or pulley I0, suitably carried by the-oor I,

and theend of the cable is secured to and fastened around a vertically disposed Winding drum Il, mounted on the car floor, This drum is provided with ratchet teeth as at`l2 which are adapted for engagement with a pawl I3 in order to retain the drum in a fixed position when the cable or cables 3 is wrapped thereabout in a taut manner. Rotation of the drum may be manually effected through the provision ofthe radially extending handle I4.

In Figs. 1 and 2, the coils of steel p'late have been disclosed in spaced groups, as indicated at a and b. While the invention is applicable to a single group of rolls or cylinders, it may, of course, be applied to two or more groups of such objects as disclosed, in which case the cable or \cables 3 is trained around supplemental guide pulleys Illa and lilb iso that the cables will pass over the.U-shaped securing frames 9 applied to each group of rolls.

In view of the foregoing, it will be seen that when the cables are tightened and passed around the rolls in the mannervindicated, the said vrolls or bodies will be positively confined against undue longitudinal movement on the deck or floor I of the transporting vehicle. The inertia forces present in the upper portions of said rolls or bodies are completely absorbed by the lashing so that the rolls cannot breakloose from their secured positions. Undue stress or strain on lthe lashing cables is minimized by the provision of vthe shock absorbing spring 5 which provides lfor limited yielding for the lashing cables during sudden starts and stops of the transporting -vehicle, but without releasing'the assembled rolls. A modified form of the invention isdisclosed -in Fig. 3 wherein the rolls 2 are placed on bottom roll. As shown in-Flg. 5,A the pulleys or guides of the type indicated at 1 io, ma and lob may be formed with brackets having depending headed studs 20, which are receivable within and removable from T-slots 2l formedin connection with the car floor. Also, the winding drum II may be similarly mounted. By this construction, the apparatus may be readily removed,'when not in use, from thecar floor in orderV to avoid .interference with the shipment of other types of objects. g

In Fig. 6,-the apparatus is shown as applied to ilat sheets 22 of metal, wherein the same results may be accomplished as in the handling of heavy bodies of cylindrical form.-

As shown in the drawing, the taut cables press on the wood blocks or frames as indicated at 9, 1- preventing the taut cables from rubbing or otherwise injuring the objects which theyY are designed to fasten. It will be noted that these blocks or frames have their depending vertical end portions terminated in planes labove the oor and the guides or pulleys, in order that such blocking frames will not interfere with the actlonof the relief springs disclosed at' and I9. Therefore,v

the play or movement made possible by the wood 7| blocks or frames supplemented by the elastic tendepending headed studs I1 positioned in T-slots T-shaped slots I8 and 2| are preferably formed` in manganese or nickel steel iioor plates, which givehigh tensile strength to vavoid accidentalv breakage of such plates under conditions of high vstrain or stress. The ends of the horizontal members of the protecting frames 9 may be grooved in order to act as guides for the passage of cables therethrough. What is claimed is:
