GRIPPING AND SECURING MECHANISM Filed May 20, 1931 Fig.1

502/01 if. A7 U21 0 c/z Patented Aug. 7, 1934 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to a gripping and securing mechanism, and more particularly to a mechanism which is adapted to grip a sheet-like member and stretch it, and, while holding said sheet-like member in a stretched condition, to nail it upon a mounting member.

In the fur trade, after furs have been sewn together to substantially the size required for making a garment or other fur article, the fur piece thus formed is moistened on the skin side, and, while still moist, is stretched upon a board or table and is nailed to the board or table around the edges of said fur piece. This operation of stretching and securing is referred to in the fur trade as nailing.

An object of the present invention is to make an improved and simplified gripping and securing mechanism.

In order to attain this object, there is provided, in accordance with one feature of the invention, a stapling mechanism having a jaw member mounted beneath the stapling mechanism and movable to grip a member adjacent an opening through which a staple is projected.

These and other features of the invention will be more fully brought out in the following description and the accompanying drawing, wherein:

Figure 1 is a view in side elevation of a mechanism embodying the present invention, and a sectional view through a board and a portion of a fur piece gripped by the device.

Figure 2 is a View in perspective of a gripping jaw and handle member embodied in the device shown in Figure 1.

Figure 3 is a view in front elevation of the device shown in Figure 1.

Figure 4 is a view in side elevation of the body portion of the device shown in Figure 1, with the jaw and handle member shown in Figure 2 removed therefrom, a portion of a staple storage chamber and handle member being broken away; and

Figure 5 is a view in front elevation of a staple adapted to be used by the mechanism illustrated.

Referring to the drawing in detail, the device comprises a stapling mechanism A of a type well known to the art, and the-mechanism of which it is not deemed necessary to illustrate in detail, as any suitable type of stapling or pinning mechanism would be suitable provided a gripping jaw could be suitably mounted thereon. The stapling mechanism comprises, broadly, a staple storage chamber 1 adapted to receive a plurality of staples, a slidably mounted operating member 2 with a striking knob 3 on the upper end thereof, so that upon striking the knob, a staple is driven down below the lower surface of the stapling mechanism. A handle 4 is fixedly secured to the stapling mechanism A and a jaw and handle member 13 is pivotally mounted on the fixed handle 4, as by means of a pivot pin 5. The jaw and handle member B comprises a thin, elongated jaw portion 6 having teeth '7 at the forward end thereof to provide a gripping surface. Side members 8 and 9, fixedly secured to the jaw member 6, comprise a yoke which embraces the handle member 4. A coil spring 11 may be mounted between the handle members 4 and 10 to normally hold these parts in separation and thereby to pivotally move the yoke member, comprising the members 8 and 9, in a counter-clockwise direction, as shown in Figure 1, thereby moving the forward end of the jaw member 6 away from the lower surface of the stapling machine. Gripping teeth 12 (see Figure 4) may be provided below a lower face of the forward end of the stapling machine to register with the toothed forward portion 7 of the gripping jaw 6. Staples 13 are stored in the staple storage chamber 1 in a well known manner, and are fed forward by a suitable spring, not shown, in a conventional manner, so that upon striking the striking knob 3 a staple will be driven downwardly, as illustrated in Figure 1. Upon release of the striking knob 3 a spring not shown will restore it to a normal position, and the spring 14 will automatically feed another staple into position for driving. I

If the device were used for a less substantial material than fur, for which the present mechanism is intended, it might be preferable to face the forward gripping portion of the jaw 6 with rubber or other suitable material and to elimihate the teeth 12, shown in Figure 4. When thus modified, the device wouldlbe well adapted for the stretching and securing of drawing paper and canvas for draftsmans and artists use.

I claim:

In combination with a stapling machine having a vertically acting striking knob'and a horizontally disposed staple magazine, a member having a yoke portion adapted to-receive said magazine and, tobe connected thereto, said member having a horizontally disposed handle portion extending rearwardly beyond said magazine, and a jaw member provided with a yoke to receive said-handle member therein and pivotally connected thereto to have gripping engagement belowsaid magazine, said second yoke having a horizontally disposed portion extending rearwardly beyond said magazine in vertically spaced relation from said first horizontally disposed handle portion.
