KNIFE Filed Oct. 29, 1937 INVENTOR BY QMQL Patented Aug. 22, 1939 PATENT OFFICE KNIFE Henry Bartosek,

Application October 29,

2 Claims.

This invention relates generally to a field workers tool and in particular relates to a hand attached knife adapted primarily for agricultural use.

The principal object of my invention is to provide a knife, arranged for attachment to a per sons hand, which is convenient to use, light in weight, and when attached to a persons hand is disposed for use without materially interfering with the manipulation of such hand for other purposes.

Another object of the invention is to provide a novel arrangement for mounting the blade on the finger saddle and at the same time provide properly spaced openings for the reception of the securing lace.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure l is a perspective view of my device as attached or laced to a persons hand.

Figure 2 is a side elevation of the device. so Figure 3 is a cross section on line 3-3 of Fig. 2.

Referring now more particularly to the characters of reference on the drawing, my improved knife structure comprises a saddle I of a length substantially that of a persons index finger and of a depth about half that of the finger. The curvature of the saddle is such that the finger will rest therein for its full length when the hand and finger are in anormal relaxed position.

A pair of ears are struck from the sides of the saddle adjacent each end and are bent downward in parallel spaced relation as clearly shown in Fig. 3. A blade 3, having its base edge a curved to correspond to the exterior curvature of the saddle on the under side, is mounted with said base edge 4 engaging the saddle and with each pair of spaced ears straddling the blade there- 'between. The ears are fixed on the base by spot welding bolted or the like.

The blade is ground with a substantially crescent shaped cutting edge 5 drawn out to a point 6 which extends beyond and away from the outer end of the saddle.

The openings in the saddle 1, formed when the ears 2 are struck out and bend downward, serve as the eyes to receive a securing lace 8. This lace is threaded between the pair of eyes adjacent the outer end of the saddle, then is crossed and each end threaded through the other pair of eyes from the inside.

1937, Serial No. 171,732

To attach the device to a persons hand the index finger is placed in the saddle beneath the lacing. The lacing is then drawn snugly against the finger, is crossed near the base of the finger, extends across the back of the hand, and finally the lengths are wound around the wrist and tied in a bow knot 9. The lace may be made of rawhide if desired and tied about the wrist as shown or secured in any other suitable manner.

As so attached to a persons hand, the knife can be handily used for many purposes such as grape picking, light pruning, cutting tying strings, and weeding where it is desirable to cut beneath the surface of the soil. While very effective, the device is light weight and does not materially hamper use of the hand. for other purposes. While I have shown and described the device as a knife, other implements such as a small cultivating or weeding fork may be substituted for blade 3.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

l. A knife unit adapted for attachment to a persons finger, said unit comprising a metallic finger saddle, a pair of ears struck from the sides of the saddle adjacent each end and forming eyes in the sides of the saddle, the ears being bent outwardly in substantially parallel and spaced relation, a blade extending lengthwise of the saddle and projecting outwardly thereof, said pairs of spaced ears straddling the blade, means fixing the blade and ears together, and a securing lace threaded through the eyes.

2. A knife unit for attachment to a finger of one hand, said unit comprising a metallic finger saddle, a blade extending lengthwise of and pro jecting outwardly from the saddle, pairs of cars struck from the saddle adjacent its ends and straddling the blade in engaging relationship, means fixing the blade and ears together and means to secure the saddle on a finger; said last named means comprising a flexible element adapted to extend over the finger above the saddle, the ears when struck from the saddle forming eyes through one pair of which the element is passed.

HENRY BARTOSEK.
