JAMES M. MAJORS. 0F OTTUMWA. IOWA.

NEUMATIC-RUBBER-TUBE AND METAL-.STEM PROTECTOR.

Specification of Letters Patent.

Patented Apr. 14, 1914.

Application filed December 1, 1913. Serial No. 804,110.,

lo alZ 'whom 'it may Con-cern Be it known that I, JAMES M MAJoRs, a citizen of the UnitedStates, residing at Ottumwa, in the county of Wapello and State of lowa, have invented a' certain new and useful Pneuni'atic-Rubber-Tube and Metal- Stem Protector, of which the following is a specification.

The object of my invention is to provide a pneumatic rubber tube and metal stemprotector, of simple, durable and inexpeir' tact with parts which would injure the threads, or the like, and from contact, with the rubber tube. Y

A further object is to provide a device of the kind just mentioned so arranged that the stem protecting part is mounted within the waterproof casing suitably adapted to contain the rubber tube.

My invention consists in certain details,

-in the construction, arrangement and combination of the various parts of the device, wherebythe objects contemplatedare attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a plan/'view of a pneu matic rubber tube andmetal stem protector embodying my invention as the same is laid out before the tube is placed in it. Fig. 2 shows a top or pla-n view of the rigid stem holding and supporting member. Fig. 3 shows a transverse, vertical, sectional view of the device 'after the stem has been placed in position and the tube folded and the side members of the casing have been folded over. Fig. 4 shows a vertical, sectional view 'taken on the line 4 4 of Fig. 3, and Fig.

5 shows a plan view of the device wrapped into a bundle with the tube inclosed therein.

My improved device comprises a sheet of waterproofing material which l have indicated in the accompanying drawings by the reference numeral 10, and which is prefer# ably rectangular in shape, as shown in Fig. 1. Sewed, or otherwise secured to the side l edges of the sheet 10 vadjacent to one end thereofg'are side wings 1-1 of similar waterproof material. l ,Secured to the strip 10, preferably approximately between the upper .rends of the wings 11, is a flap '12. 'vlhe flap ,.12 ispr'eferably secured along its upper edge,

as shown in Fig. 1, so that the llower-portion thereof is free to move. Arranged longitudinally of the flap 12, adjacent to one.

end ofthe portionfthereof which is free to move', and preferably near the edge of the strip v10, as 'shown by the dotted lines in Fig. 1, and incross section in Fig. 3, is'a rigid metallic tube supporting member 13. VThe end of the member 13, adjacent to the neares t edge of the strip 10, as shown at B in Fig. 3, is thicker than the other endof said member 13,.v as clearly shown in said tigure. Extending longitudinally through the thicker portion of theend B of the member 13 is an opening li'designed to receive the stem-15 of an inner tube. ,The opening 14 is so located that the free end of the tube,

' when inserted in said opening, ifl long enough, will extend through the opening and rest just above the thinner end of the member 13, as clearly shown in Fig. 3.

Secured to the upper ysurface of the thick end B of the member 13v is a spring device which may be made of two parallel flat springs 16 which extend beyond the thick portion B to points above the thinner end of the member 13. The free ends of the springs 1G form bearings 17 for a small shaft 1S on which, between the springs 16, is mounted a rubber roller 19. IThe roller 19 extends down to a point slightly below the level of the upper part of the hole or opening 14 and is adjacent to the thick portion B of the meniber 13, and is designed to yieldingly engage the free end of the stem 15, as shown in Fig3.

Secured to the flap 12, and covering the rigid supporting device 13, is a second flap 20 which is fastened only adjacent to its end near the thick portion B so that its other end is free to be raised or folded out .of the way.

ln the practical use of my improved device. the flaps 12 and 20, and the rigid supporting device 13 are raised slightly and the stem 15 of an inner tube 21 is inserted in the opening 14 withA its free end projecting through said opening above the thinner part of the niember13. One portion of the tube 21 is then extended under the flap 12 and the other portion is extended over the flap and the remainder of the tube is then folded into coils, as shown in Fig. 3. The wings 1l are then folded over the folded tube 21, and the lower and upper'parts of the strip 10 are folded over and the bundle thus formed may be tied with theflexible devices 22, forming a comparatively small and compact package.

The strip andthe Wings 11 being made of waterproofl material will protect the rubber from contact with oil or moisture, thereby thoroughly protecting it. The construction and arrangement of the rigid supporting device 13 is such that the metal stem 'is firmly supported and is yieldingly held against rotation and against removal by the.

rubber roller 19.

The portion B is preferably of such thick# ness that the curved metal shield 23, `found on the ordinary inner tube, extends only a short distancev above and below it so that there is littlev likelihood of the tube being cut on said metal part. c

The stem 15 may rotate in the opening 14 slightly for adjust-ing the parts vin position and on that account it is not likely that the rubber will be torn in placing the tube in the casing. The tube, when placed in my casing, can be put in the ordinar toolbox or in any convenient place, and wi l be safe from contact with metal tools'or hard parts which might otherwise bruise or injure it. The

tube can be readily folded intov a comparatively-small space and can be Wrapped ,so that the rubber practically does notchfe or rub.

It may be noted that by placing the stem `tube during the process of folding.

It is understood that numerous changes may be made in the details of the construction of my device without departing fromits essential features and it is my intention to cover by this application any such changes which Vmay be included within the scope of the appended claims.

I claim as my invention:

k A 1. In a device of the class described, a

flexible Waterproof casing, vazrigid supporting device, flexibly secured thereto, having a thickened end provided with an opening extending through it to receive the stem of a rubber tube so that the stem may projectl above the thinner portion of said supporting device, and a non-metallic device for yieldingly engaging'the free end of said stem.

2. In a device'of the class described, a flexible Waterproof covering, a flap secured thereto along one edge, a rigid supporting device secured to the loose portion of said flap near one edge thereof, said sup-porting device having a thickened end provided with a `longitudinal opening to receive the stem of an inner tube, a non-metallic yielding device arranged to engageI the end 'of said stem, and a second flap arranged to cover said ri id supporting device.
