To all whom it may concern:

Be it known that we, ADELIN GISLAIN AUGUSTE SORNIN on LEYSAT and CHARLES DENIS DISCRY, subjects of the King of Bel-' gium and residents, respectively, of Etterbeck: russels, Belgium, and of Ixelles- Brussels, Belgium, have invented certain new and useful Improvements in Apparatus for Insuring the Correct Position of the Fingers and Hand in Writing, ofwhich the In order to write well and rapidly it is necessary to observe the following principles:

1. The pen must be held lightly between the thumb, the index finger and the middle.

finger in such a manner that the pen passes across the third joint of the index finger and points toward the right shoulder for sloping writing, while forupright writing the pen is raised a little.

2. The thumb, index finger and middle finger must be allowed the necessary freedom of action. These fingers, which form a mobile support for the pen, must be freed from the third and fourth fingers.

3. The third and fourth fingers must be united, depressed and maintained in a posi tion approximately perpendicular to the forearm and must serve as a support for the hand.

4. The wrist must be maintained nearly one centimeter above the paper, more than half of the weight of the right forearm being supported upon the edge of the writ ing desk.

he present invention provldes an mproved apparatus for holding the third and fourth fingers separated from the remaining fingers in accordance with the principle set forth above and the invention consists, briefly stated, in an improved device for insuring the correct position of the fingers and hand when writing comprising a substantially rigid member pivotally secured at one end to a wristlsi and ada ted to engage and hold the third and fourth. fingers at its free end.

In order thatthe invention may be more readily understood, the reference willnow be made to the accompanying drawings inwhich Figure 1 is a plan of the apparatus, showingthe rigid member separated from the wristlet,

Fig. 2 is an elevation and j I Fig. 3 is a perspective view-showing the apparatus applied to the hand. 7

The apparatus comprises essentially two parts: an adjustable wristlet 1 of leather, rubber, fabric, celluloid, metal or other suitable material and a removablestrap 2 adjustable in length and formed from a thin steel strip, one end 3 of which is curved to form a clip adapted to hold the third and fourth fingers together in the position shown in Fig. 3, that is to say in a position approximately perpendicular to the forearm. The two members 1 and 2 are united by means of a circular plate 4 provided with slots 5 through which the .wristlet 1 is threaded. The strap 2 may be secured to the plate 4 by means of a Screw which passes through one of a number of holes 6 formed in the strap 2 and engages in the plate 4 or in any other manner. As shown in the drawing, the circular plate 4 carries a universal joint 7 upon which the strap 2 is secured by means of a screw 8, this arrangement also allowing movement of the strap in any direction without altering the distance of the end' 3 of the strap from the plate 4 when once this is fixed.

The operation of the device is as follows The wristlet is lightly fastened upon the wrist above the joint with the clip turned opposite to the back of the hand and the clip formed upon the end 3. of the strap is,

Owing to its rigid nature, the steel strap 2 maintains the third and fourth fingers in the position already indicated and allows them readily to fulfil their function as a means of support for the hand and to glide easily over the paper. The thumb, index finger and middle finger are entirely detached from the third and fourth fingers and have perfect freedom to execute all strokes necessary in writing. In short the apparatus insures that the fingers are properly disciplined for writing while avoiding for the user, writers cramp and other effects of fatigue which interfere with the regularity of the writing and the speed of the writer.

These important advantages render-the invention suitable not only for infant schools where it is of great use for children learning to write, but also for more advanced scholars who are often under the obligation of making rapid notes, forprofessional writers, draftsmen and the like.

We claim I 1. Apparatus for insuring the correct position of the fingers and hand in writing, comprising, a wristlet, avcircular plate secured upon said wristlet, a thin steel strip having two ends, an adjustable pivotal connection between said plate and one end, of

said steel strip and means for, engaging and holding the third and fourth fingers of the hand in the other end of said steel strip.

2. Apparatus for insuring the correct po- 'sition of the fingers and hand in writing comprising a'w'ristlet, a circular plate secured upon said wristlet, a universal joint,

mounted upon said plate, a thin steel strip having two ends, an ad ustable connection between said universal joint and one end of said steel strip and a clip formed upon the other end of said steel strip.

3. Apparatus for insuring the correct position of the fingers and hand in writing comprising a wristlet, -a circular plate secured upon said vwristlet, a substantially rigid connecting member having two ends, a pivotal connection between said plate and one end of said connecting member, and means for engaging and holding the third and fourth fingers of the hamlet the other end of said connecting member.

In testimony whereof we affix 0ursigna tures.
