March 4, 1941. N: SANDERS PAC AGED TUBE Filed July 18,. 1939 EZMEE AZZEHNQ I /Q axflqy r r l I I ink/4i Patented Mar. 4, 1941 PATENT ()FFICE PACKAGED TUBE Elmer N. Sanders, Ellwood City, Pa., assignor to National Tube Company, a corporation of New Jersey Application July 18, 1939, Serial No. 285,212

3 Claims.

This invention relates to the problem of shipping tubes and pipes, and is particularly concerned with the problem of packaging still tubes made of steel and having ends machined to very close tolerances. both inside and out, which must be positively protected against damage during shipping.

A specific example of the invention is illus trated by the accompanying drawing, in which:

Figure l is a longitudinal section of the example; and,

Figure 2 is an end view of the same in a partially completed condition.

More specifically, this drawing shows the machined end portions of a still tube I such as has been previously mentioned. It is imperative that their ends be protected inside and out during shipment of the tube, and it is highly desirable that the remainder of the tube reaches its destination in the same condition as when it left the mill.

According'to the present invention, each end of the tube I is protected against rusting by a layer 2 consisting of wrapped cheese cloth saturated with rust-inhibiting grease. The end of of the tube from mechanical damage, as well as to preserve the greasy layer 2 during shipment. A cross bar 5 is fixed transversely across the inside of the part 4 and is spaced from its extreme end for the purpose of effecting protective engagement of an attachment means in the form of a tension rod 6 extending from end to end of the pipe through holes in the closure 3 and bar 5, and which is fixed to the latter by way cl. a nut 1.

The above arrangement leaves an annular rim 4a which protects the threaded end of the rod 6 and the nut screwed thereon against mechanical injury. To assure an aboslutely tight seal, the space within this annular rim 4a is filled with a cementitious material 8 which is molded over the nut I and the projecting end of the rod 6, this material covering the bar 5 and sealing all other portions of the end.

Protection of the main body of the tube is efiected by wrapping the tube with a rubber tape to provide an elastic layer 9, this layer extending a short distance between the tubular part 4 and the machined end portion of the tube as at 9a. The result is a packaged still tube that can be shipped with safety.

I claim:

1. A tube or pipe end protector including a tubular part adapted to fit over said end and having a cross bar fixed transversely across its inside spaced from its extreme end for the purpose of effecting protected engagement of an attachment means and a closure for the tube or pipe end having annularly stepped parts fitting the inside and end of the tube or pipe end, said closure being adapted for use inside said'transverse bar and the latter functioning to position said closure.

2. A packaged tube including a closure for the end of the tube, greasy material over the outside end portion of the tube, a tubular member over said material with an end extending beyond said closure and cementitious material filling the extending end of said member, said extending end having a bar fixed transversely across its inside spaced from its extreme end, said bar engaging and positioning said closure and providing eng'agement for attachment means in the form of a tension rod extending to the other end of the tube and passing through said closure, said cementitious material covering said bar and the end of said rod engaging said bar.

3. A packaged tube including a closure for the end of the tube, greasy material over the outside end portion of the tube, a tubular member over said material with an end extending beyond said closure and cementitious material filling the extending end of said member, said extending end having a bar fixed transversely across its inside spaced from its extreme end, said bar engaging and positioning said closure and providing engagement for attachment means in the form of a tension rod extending to the other end of the tube and passing through said closure, said cementitious material covering said bar and the end of said rod engaging said bar, the body portion of the tube carrying a layer of elastic material then enters a short distance between the inner end of said member and the end portion 0! the tube.
