Feb. 17, 1959 N. JACKSON DEVICES TO TEMPORARILY HOLD AND MANIPULATE PUNCTURING TOOLS Filed March 20, 1957 United States Patent EVICES TO TEMPORARILY HOLD AND MANIPU- D LATE PUNCTURING TOOLS John N. Jackson, Port Burwell, Ontario, Canada Application March 20, 1957, Serial No. 647,355 2 Claims. (Cl. 223--104) This invention relates to devices to temporarily hold and manipulate puncturing tools, and the object of the invention is to provide a simple and sturdy tool that w1ll afford ample lateral support to a puncturing tool, such as a needle or a small-headed nail, and so hold it against distortion or breakage while being pushed, through the medium of the device, through one or more thicknesses of contacting layers of such relatively tough matenal as duck, paper, canvas, and relatively thin sheets or layers of wood. A needle may be manipulated through the medium of this device to sew together one or more layers of thick and heavy cloth, or fasten together relatively thin sheets of tin, copper, zinc, or lead, as hereinafter more particularly explained.

Fig. 1 is a side elevation of the tool w1th the pressurebar in its lowest position in the tool chamber.

Fig. 2 is a longitudinal section through one side of the tool chamber showing the pressure bar partly withdrawn therefrom.

Fig. 3 is a longitudinal section through one side of the tool chamber showing a threaded needle therein partly pushed through two layers of material to be sewn together.

Fig. 4 is a cross section on the line 4-4, Fig. 3.

In the drawings, like characters of reference refer to the same parts.

the tool comprises a tubular tool chamber 2 provided in one side thereof, through its lower end, with a slot 3 of any desired length. This slot must open through the lower end of the chamber 2, and lie parallel to the longitudinal axis of this chamber.

As shown in Fig. 3, the thread 9, carried by the needle 8, passes freely through the chamber 2 and out therefrom by means of the slot 3 formed in the side of said chamber (see Fig. 3 of the drawings), during the sewing operation, and as this slot, as shown in the drawings, extends through completely the wall of the said chamber 2 at no time can it oifer any resistance to interfere with the sewing operation as the thread or wire passes therethrough.

The upper end of the chamber 2 is exteriorly provided with a ring 4 through which slides the tool herein called a pressure-rod 5 into the chamber 2.

So that the pressure rod 5 may be easily grasped by the hand for manipulating, it is provided, in any suitable way, with a fixed finger grip 6. Although not essential to the careful manipulation of the tool, the finger grip 6 is preferably provided with an extension 7 of smaller "ice diameter than that of the finger grip itself. If an extension is not used the finger grip will contact the supporting ring 4 when the pressure rod 5 is fully moved into the chamber 2, and therefore confusion may arise in handling the tool because of the proximity of these elements 4 and 6, when they are brought together. To avoid any chance of confusion in the handling of this device the extension 7 is preferably used.

This tool can be used to insert small fastening devices such as pins, needles, and small-headed nails, in many locations.

As shown in Fig. 3 a needle 8 is held in the tool chamber 2, and therefore it will be understood how other small fastening devices will be held in said chamber 2 for insertion in any given place.

Held in the eye of the needle 8 (Fig. 3) is a linen thread 9 (or a string, or even a metal wire of small diameter) which may be sewn into the material it is desired to operate upon.

The thread carried by the needle 8 will extend through the longitudinal slot 3 formed longitudinally in one side of the chamber 2 which houses the tool to be used.

In Fig. 3 are shown two layers of any suitable material 10, to be sewn together.

The needle 8 is of course placed within the tool chamber 2 in the position shown before the said chamber is placed and held by hand in contact with the material to be sewn. By depressing the pressure rod 5 the needle is passed through the layers 11, and then by pulling on the projecting end of the needle beyond these layers the first step in the sewing of these layers together is carried out. The next step is to turn the work over and repeat the operation just described, and so alternately until the sewing operation is completed.

I claim:

, 1. A tool of the class described comprising a straight tube forming a chamber of uniform diameter throughout its length, and provided with a longitudinal slot extending completely through the wall of said tube for the major portion of its length and opening through one end of said tube; a supporting ring fastened exteriorly to the other end of said tube and having a passageway therethrough in alignment with the passageway through said chamber; a straight pressure rod adapted to be moved in sliding contact with the chamber and longitudinally thereof and through said supporting ring, and a finger grip fastened to the upper end of said pressure rod, said rod being longer than said tube and being extendible through the outer end of said tube.

2. The tool as set forth in claim 1 characterized in that an extension is provided on the under side of said finger grip of lesser diameter than that of said finger grip and said supporting ring.
