Description

April 1930. J. w. HCDGSON Q 1,754,556
PLUG INSERTING NEEDLE Filed July 2, 1928 Inuenior: 16/222 MZliam Jiodyoron, ,y w W Patented Apr. 15, 1930 UNITED STATES PATENT OFFIQE JOHN WILLIAM I-IODGSON, OF AKRON, OHIO, ASSIGNOR TO iI-IE MILLER RUBBER 00., OF AKRON, OHIO, A CORPORATION OF OEIIO PLUG-INSERTING NEEDLE Application filed July 2, 1928.
My said invention relates to improvements in tire repair devices of the type employing a wire helix designed to be engaged with the stem of a rubber plug.
The present invention is aimed to provide a construction which may be made with a helix of lighter wire which facilitates the insertion of the stem of the plug, and which will be guarded in such a way that its coils will not be subjected to strain when passed through the wall of the tire. To this end, the invention comprises the novel construction hereinafter described and defined by the appended claim.
lhe said invention is illustrated in the accompanying drawing in which:
Fig. 1 is a plan View of the tire repair device constructed in accordance with my invention with the sleeve in retracted position and partly broken away and with the helix engaging the stem of the plug.
Fig. 2 is a similar view with the sleeve or guard in the position which it occupies when the needle is ready to be forced through the tire wall.
Us eter than the exterior diameter of the said cylindrical portion.
The said cylindrical portion preferably terminates in an annular shoulder a for the purpose hereinafter described, and the needle is provided at the opposite end with a penetrating point, and at a suitabledistance back from said point with an eye to receive a pulling device; such for example, as a wirenail. 4: designates a protecting sheath which is in the form of a tube or cylinder having a bore to slidably fit the helix, and the cylindrical portion carrying the same, and having adjacent its forward end, a reduced bore to provide an internal shoulder 4 to coact with the shoulder of the needle to limit movement of Serial No. 289,986.
the sheath in the direction of the plug 1. Said reduced bore snugly tits the needle, though freely slidable thereon, and the sheath is provided adjacent its forward or inner end with a beveled edge indicated at 4 After the plug has had its stem inserted in the coils of the helix, as shown in Fig. 1, the sheath is moved towards the plug 1 until it cempietely incloses the coils of the helix, whereupon the needle can be readily passed through the tire, carrying with it the sheath and inclosed helix and stem 1 of the plug. When the head of the plug has been properly seated against the inside of the tire, the sheath may be withdrawn and the helix disengaged from the plug.
Having thus described my invention, what I claim is:
Means for repairing a tire puncture comprising a needle having at one end an open helix, a tubular sheath removably inclosing said helix, and means for limiting the movement of the sheath on the needle in the direction of the helix.
In testimony whereof, I afiix my signature.
JOHN -WILLIAM HODGSON.
