Nov. 12, 1957 C. A. DORSEY METHOD oF LOADING AND PROTECTING NEWSPRI'NT ROLLS DURING TRANSIT Filed June 2, 1952 INVENTOR ATTORNEYS United States Patent O METHOD F LOADING AND PROTECTING NEWSPRINT RLLS DURING TRANSIT Application June 2,1952, Serial No. 291,235

Claims. (Cl. 10S- 367) This invention relates to a means and ymethod for pro- ,tecting rolls of paper, such as newsprint and the like, during transit thereof, against damage, more particularly to the ends of such rolls.

In shipping rolls of newsprint paper and the like, the term newspriint being used herein merely for convenience of reference, and not as a term of limitation, such rolls are usually wrapped and in s ome instances are provided with end caps, generally of paper and sometimes of other materials. These rolls of paper are usually shipped from the paper mills to the consumer, in ordinary railroad boxcars, The rolls are stood onend and according to size, there may be thirty-tive rolls, more or less, in a carload. Upon arrival at their destination, it is veryl seldom that all the rolls `arrive in acceptable undamaged condition. There are practically ,always a number of rolls of which the ends are badlly damaged, these being the ends on which the rolls stand during shipment. Depending on the extent of damage the rolls are either entirely rejected or else are re-rolled to eliminate the damage. The damage is often in that the ends are worn or pounded down, generally referred to as llattened, and, therefore, cannot go on the press where they are to be used, unless rerolled. This damage has long been a matter of considerable loss and annoyance and a solution to the problem `has long been sought.

These rolls of paper are so packed in the cars for shipment that they have a certain amount of room for movement, this being very small but enough so that when the car is shifted around and also during the travel of the car on its rails, the rolls tend to shift towards each other. I have discovered that this tendency towards slight shifting, while it is unavoidable, and in a sense necessary, is the reason for the damage. The cars in which the rolls are shipped are not always used only for the shipment of these rolls of paper but are used for shipment of all sorts of cargo. Generally, the floors of the cars are rough. I have discovered that if a means is provided whereby the rolls of paper can slide on their ends on the door of the car, the little distance of movement they need, that instead of the ends becoming llattened or otherwise damaged, the rolls larrive in perfect condition. lt is the lack of ability to shift around smoothly and slide over that causes the rolls to grind their ends on the iloor or to grind their sides against the sides of the car and to thus become damaged on the ends or on the ends and sides. The regular jolting action of the car when riding along on the rails tends to make the rolls dance around on their ends, which normally they are prevented from doing and thus become damaged.

With ythe above and other objects in view, my invention consists in the arrangement, combination `and details of construction disclosed in the drawing and speciiication, and then more particularly pointed out in the appended claims.

In the drawing:

`Figure l is a horizontal section showing diagram- 2,812,727 Patented Nov. 12, 1957 matically a freight car having a plurality of newsprint rolls mounted therein.

Figure 2 is a fragmentary sectional View on an enlarged scale taken on the line 2-2 of Figure l. i

Figure 3 is a fragmentary sectional view on a further enlarged scale similar to Figure `2.

Figure 4 is a perspective View of one of the covering sheets for the car oor.

Referring to the drawing, the numeral 10 designates generally a freight car and the numeral 11 designates the floor ofthe car 10. A plurality of newsprint rolls 12 are placed within the car 10 and are normally set up on end substantially after Ithe manner shown in Figure l'. VIn the movement of the `car 10 from the consignor to `the consignee, the car 10 is subjected ot severe jolts due partly to the roadbed and partly to the stopping and starting of the train. These jolts to which the car 10 is subjected cause the rolls 12 to .shift within the car, and this shifting movement causes the bottoms of the rolls to become damaged. The damage to the bottoms of the rolls and also to the sides of certain ones of the rolls which rub on the sides of the car 10 is frequently Such as to require rewinding of the rolls so as to eliminate damaged portions of `the paper, and it is not unfrequent that a very substantial amount of paper is affected.

In order to provide a means whereby the rolls 12 may `be permitted to have slight movement on `the floor r11 `of the `car 10,` lhave provided a sheet 14 which may be a paper or fibrous sheet which is laid flat on the iloor 11 of `the carlo.

The upper surface of the sheet 14 is provided with a relatively anti-friction surface 15, andthe surface 15 may be formed by coating or impregnating the sheet 14 with wax, lamp black or other material which will produce a relatively slick or anti-friction surface. It will, of course, be understood that the side walls 13 of the car 10 with the end walls 16 may also have coated sheets 14 secured thereto so that the sides of the rolls 12 will contact with the sheets on the inner surfaces of the side and end walls of the car. It is the practice to cover each roll 12 with a wrapper sheet 17, and this wrapper sheet 17 extends over the opposite ends of the roll 12, as indicated at 18.

The wrapper 17 may also be coated or impregnated, as indicated at 19, with an anti-friction coating or impregnation so that the bottom end of the roll 12 will have a relatively slick or anti-friction surface for engagement with the surface 15, and the vertical sides of the rolls 12 will also have a similar slick or anti-friction surface adapted to slidingly contact with the sheets on the sides and ends of the car 10.

In addition, the upstanding rolls 12 may also contact one with another and the slick or anti-friction surface of each wrapper will prevent any scraping .action of one roll relative to the other as the rolls come into contact with each other.

The anti-friction coating 15 is herein disclosed as being formed on at least one surface of the sheet 14, but it will be understood that this anti-friction surface may in certa'in instances be formed directly on the upper surface of the floor 11.

It will be understood that normally the floors of the freight cars are normally relatively rough, but where these floors are relatively smooth, as where a new car is being used, or the floor has a metal surface, the coating 15 may in such instances be applied directly to the lcar Hoor.

While l have shown the wrapper 17 as being coated or impregnated with the anti-friction surface 19, it will be, of course, understood that this anti-friction surface 19 may, if desired, be applied only to one or both ends of the rolls. In addition, in certain instances the ends or sides of the rolls may be uncoated and in other instances, the licor covering may be omitted and the antifriction coating applied only to the ends and/ or the sides of the rolls.

I do not mean to confine myself to the exact details ofconstruction -herein disclosed, but claim'all variations falling within the purview of the 4appended claims.

What is claimed is:V

1. In a method of loading newsprint rolls for shipment in fa freight car the steps which include covering the floor of a freight car with anti-friction material, and substantially filling the floor area of the freight car with a plurality of newsprint rolls with their longitudinal axes substantially perpendicular to the floor of the car for damage free relative sliding movement thereon.

2. In a method of loading newsprint rolls for Vshipment in a freight car the steps which include covering the floor of a freight car with waxy material, and substantially filling the floor area of the freight car with a plurality of newsprint rolls with their longitudinal axes substantially, perpendicular to the lloor of the car for damage free relative sliding movement thereon.

3.-In a method of loading newsprint rolls for shipment in a freight car the steps which include coating the flat lower end of each of a plurality of newsprint rolls with an anti-friction material, and substantially filling the floor area of the freight car with the coated newsprint rolls with their longitudinal axes substantially perpendicularto the floor of the car for damage free relative sliding movement thereon.

4. In a method of loading newsprint rolls for shipment in a freight car the steps which include covering the oor of a freight car with a fibrous sheet having an antilfriction coated upper surface, and substantially filling the licor area of the freight car with a plurality of newsprint rolls with their longitudinal axes substantially perpendicular to the oor of the car for damage free relative sliding movement thereon.

5. In a method of loading newsprint rolls for shipment in a'freight car the steps which include covering the floor of a freight car with a fibrous sheet having an anti-friction coated upper surface, covering the flat lower end of a plurality of newsprint rolls with an antifriction material, and substantially filling the floor area of the freight car with a plurality of newsprint rolls with their longitudinal axes substantially perpendicular to the licor of the car for damage free rela-tive sliding movement thereon.
