16 Claims.

'Ihis invention relates to inliating tools or needles for inflatable articles such as football bladders, play balls, or the like, and has particular reference to means for providing such a needle with a self-lubricating attachment whereby the needle will become lubricated in its normal manipulation without special attention or eiort on the part of the operator.

It is more or less common at the presenti-time to provide inflatable articles such as football bladders or the like with an inflating neck'having an opening therein communicating with the interior of the ball, through which a needle may be inserted for purposes of inflation, which opening will be self-closing. In some structures of this character, a plug extends through the iniiating opening or passage into the ball, which plug will completely close the opening against outward leakage of air when the needle is withdrawn. In structures of this character it requires more or less force to insert the needle as it is usually necessary to spread or pry apart to some extent the walls of the passage to admit the needle, and there is for this reason considerable friction between the walls of the passage and the needle.

Lubrication of the needle reduces this friction to a considerable extent and renders much easier the passage of the needle into and out of the opening. It is of course also advantageous if such lubrication may be accomplished automatically in the use of the needle and thus obviate any attention or effort on the part of the operator to effect this result.

One object of the invention, therefore, is to provide an inilating needle with lubricating means which will be self -operative during the normal use of the needle.

Another object of the invention is the provision of an inflating needle with a lubricating attachment through which the needle will be moved when being inserted into the bladder or other article to be inflated.

A still further object of the invention is the provision of an inlating needle having a container surrounding the shank of the needle adjacent the open end thereof, which container may carry a lubricant and which will be slidably retained upon the needle so that the latter may be protracted therefrom to be inserted into the article to be inflated.

Still another object of the invention is the provision of an inating needle having a surrounding housing containing a lubricant, the

housing being provided with an opening through L which the needle may be protracted and retracted Rubber Company, Inc.,

Conn., a corporation of Massachu- 1935, Serial No. 16,043

in the inflating operation in Contact with the lubricant whereby the needle will be automatically lubricated during its use.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the drawings:

Fig. l is an elevational view of an inflating needle embodying my invention;

Fig. 2 is a View showing the needle inl inating position in a football bladder or the like, the latter being shown in a fragmentary manner in section;

Fig. 3 is a sectional view of the needle and associated parts shown in Fig. 1;

Fig. 4 is an end view of the structure shown in Fig. 1;

Figs. 5 and 6 are sectional views of slightly modified forms of my invention;

Fig. '7 is an elevational view of a modified form of my invention;

Fig. 8 is a sectional view of the modication shown in Fig. 7;

Fig. 9 is an end View of Fig. 7; and

Fig. l0 is a section on line I-I of Fig. 8.

In order to illustrate a preferred embodiment of my invention, I have shown particularly in Figs. 1 and 3 of the drawings an inating needle I0 secured at its upper or entrance end to a nipple I I, which nipple may be secured by a short length of rubber tubing or the like I2 to a second nipple I3 provided with a threaded bore I4 and external threads I4a to adapt it to be secured to the delivery end of an air pump. The needle III is, in its usual form, hollow to provide for the passage of air therethrough and is provided with an opening I5 at its lower or nose end to permit the passage of air therefrom into the article to be iniiated. In Fig. 2 of the drawings I show such a needle inserted into the opening I 6 in the inflating neck I'I 'of a football bladder I8, for example. A rubber plug I9 is disposed within the opening I 6 and serves to close this opening against escape of air when the needle is withdrawn.

The lubricating device shown in Figs. l to 4 of the drawings comprises a. pair of spaced collars 26 and 2| which are connected by oppositely disposed

arms

22 and 23. These parts may and will preferably be made of rubber, so that the collar 20 maybe slipped over the rubber tube I 2 as shown in Fig. 3, the collar being of such a size that it will be slightly expanded in this operation and so will grip the tube I2 so as to be securely held thereon.v 1 Y The lower collar 2| is provided with a bore or opening 24 through which the needle extends, the bore extending entirely through the collar so that the needle may be protracted therefrom by moving the collar toward the nipple and doubling or folding the

arms

22 and 23, as shown in Fig. 2. This permits the protraction of the needle so that it may enter the iniiating opening I5 to a sufficient extent to effect communication between the opening I5 and the interior of the bladder.

Within the collar 2| is a cup-shaped container- 25 containing a lubricant 26, the container being provided with an opening 21 in its closed end which is provided for the passage of the needle. As shown in Fig. 3 at 28, the end of the collar covers the end of the container so as to retain the lubricant therein, except, of course, for the opening 24 through which the needle is permit ted to pass.

It will be apparent that the outer wall of the needle at the delivery end thereof is in direct contact with the lubricant 26, and when the needle is protracted, as shown in Fig. 2, the wall of the needle will be lubricated so as to permit its easy entrance into the opening I6 of the bladder. When the needle is removed from the bladder, the

arms

22 and 23 will straighten out and cause the collar 2| to move outwardly over the surface of the needle until it reaches the position shown in Figs. 1 and 3. When inserting the needle in the bladder, it is only necessary to restrain movement of the collar 2|, as by contact with the article to be inated, and slight pressure upon the needle will cause it to project from this collar and the end can then be inserted in the opening in the bladder, the

flexible arms

22 and 23 foldingA upon themselves to permit this operation. It will also be apparent that I haveprovided by this means a lubricating attachment which may be suppliedv and used with infiating needles already in use as itY may be attached to any needle by merely slipping the collar 20 over the inflating tube I2 to which the needle is attached.

In Fig. 5 I have shown a slightlygmodiiied form of my invention wherein the collar 2 IEL which corresponds to the collar 2| previously described is hollow, whereby a lubricant container 29 may be inserted within the hollow collar and held therein merely by being grippedV by the rubber wall of the collar. In this instance, the container 29 may be completely closed, asshown, to house the lubricant 30, except that registeringY openings 3| and 32 are provided for the passage of the needle. The lubricant container in this case as well as in the form of my invention previously described will preferably be made of metal.

In Fig. 6 of the drawings I have shown a further modiflcation similar to that shown in Fig. 5 except that the container 29a may be held in position by metal bands or

wires

33 and 34 which surround the collar 2|, These bands may be used when it is not desirable to depend upon the gripping action between the rubber and the container. Also, if desired, thecontainer may be provided with annular recesses 352 and 36 to receive portions of the collar forced inwardly by the

bands

33 and 34. The container will then be positively and securely held in place.

In all forms of my invention, it willbe necessaryfor the needle, in order to be inserted into the article to be inflated, to be moved through the lubricating means so that the wall of the needle will be lubricated to provide for itsreasy passage through the inflating nipple and thus make it impossible for anyone to use the needle without lubricating it.

In Figs. 7 to 10 of the drawings I have shown a further modiiied form of inflating needle in which the collar 4S is of extended length so as to receive in one end the nipple 4| adapted to be attached to the inflating pump, and to receive in the other end the base end or nipple 42 attached to the hollow inflating needle 43. It will be understood that a section of the collar 40, which is made of rubber or similar flexible material, remains between the nipples 4| and 42 so as to provide a flexible connection between the needle and theA nipple 4| attached to the pump, in the same manner as is provided by the tube I2, shown in Figs. l to 3. The extended collar 40 in this instance takes they place of both the tube l2 and the collar 20 of the modification of my invention previously described.

To, the collar 40 are attached

flexible arms

44 and 45 which connect it with a second collar 46, to which the ends of these arms are attached, this collar being in spaced relation to the collar 40.

Within the collar 46V is a container 41 for a lubricant or the like 48. The container may conveniently be made of metal and is provided' with

end openings

49 and 50 for the passage ofthe needle 43. It will be understood that the collar 46 will preferably be of rubber or some elastic material, and by its elasticity grips the container 41 and holds it in place. The container may be provided with a flange 5|' projecting laterally from a point adjacent its lower end, which will limit its entrance into the collar.

The arms 44 and 45u may be provided with the

longitudinal ribs

52 and 53, which also may extend over the collars 40 andy 46. These ribs impart greater rigidity to the arms andv provide for amore positive return to their straight position after they have been folded, as shown in Fig. 2;

While I have shown and described some preferredY embodiments of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the in Vention and within the scope of the appended claims.
