Application led January 4, 1915.
or attachments to pen holders or pencils, for
use in securing a correct position of the hand in writing and to prevent finger-movement, and more particularly an improved device of the character illustrated in Letters Patent No. 900,716 issued to me on October 13, 1908, for a pencil holder.
` The object ofmy present invention is to provide a simple and inexpensive device of the character referred to, which shall. be of small size, so as to occupy very little space, and adapted to be easily and quickly adjusted to lit upon hands of different sizes when attached to a pencil or pen holder for use'in writing, and not liable to injure the hand of the user bykcontact with a sharp edge.
The invention or improvement will first be hereinaftel` more particularly described, with reference to the accompanying drawings, which are to be taken `as a part of this Y specification, and then pointed outv kin the claims at the end of thedescription.
In said drawings: Figure 1 isa perspective view of myV improvement attached to a pen holder and applied to a hand indicated in dotted lines to illustrate the applif cation of the device in practical use; Fig. 2
is a longitudinal sectional `view ofthe at-4 tachment illustrating its application to a pencil or pen holder, a portionof which is indicatedin dotted lines; Fig, B is a detail sectional view taken on the line 3-3 Vof Fig. 2, looking in the direction of the arrow; Fig. t is a perspective viewof the upper member of the device detached.; Fig. 5 is a I perspective view of the lower member detached; and Fig. 6 is a cross section taken on the line 6-6 of Fig. 2.
Referring to said drawings, in which the same reference letters are used to denote corresponding parts in different views, the
letter A denotes the upper member of the` attachment consisting of anparm a having Specification of lLetters Patent.
Vangle thereto, approximately a right angle,
and with a spring clasp b2, said shank b1 being preferably integral with said arm and spring clasp; the latter being adapted to receive a pencil or pen holder and clamp the two members of the attachment thereto, as shown in Figs. 1, 2 and 3 of the drawings.
The shank b1 is also formed or provided with a lug or protuberance b3 adapted t0 engage any one of the apertures a2 in the shank of the member A, for the'purpose of securing the two members together with their projecting arms arranged at any desired distance a-part to adapt the device to be applied to the hands of different individuals having small or large hands. The edges or marginal portions of the arms o and o are preferably turned back so as to provide a marginal rib or bead to prevent injury to the hand by contact with a sharp edge. Both arms a and Z) are preferably resilient, though the lower arm may be sti' or rigid. The arm a is designed to pass over or partially across and conform to the shape of the back of the hand, while the arm b, which is preferably rigid or less resilient than the arm a, is designed to set within or against the palm of the hand, so that the two arms will embrace the hand between them, or that portion of the hand between the thumb and forelinger. As shown, the arm o projects substantially at right angles from the shank thereof, while the arm a projects at a slight inclination to its shank and is curved to conform to the curvature of the back of the hand on which it rests. As shown, the shank of the upper arm, having the series of apertures therein, is considerably longer than the shank of the lower arm, which has the lug or protuberance thereon adapted to engage the apertures in the shank of the longer arm, but it is obvious that the in which position thedevice Ais ready in which case the shank of the lower arm would be placed underthe shank of the upper arm and the position of the lug or protuberance and the perforations would be transposed, the lug being on the shorter shank and the perforations in the longer ing the arms which embrace the hand at different distances apart, the shank of one arm resting upon the pencil or pen holder and the shank ,of the other arm resting thereon, so that the former is clamped betweenthe pencil and the shank of the larm which carries the spring clasp, thereby securing all of the parts together.
The operation of the invention will be readily understood from the foregoing description, when taken in connection with the accompanying drawings. Having secured the two members together with ,the arms at the desired distance apart Y and with the pencilv or pen holder in the clasp, as shown in Figs. l, 2 and 8 of the drawings, the scholar or other person using the device will place between the -.two arms of the attachment that portion of 'his or her hand' which lies between the thumb and forenger, at the same time taking hold of the pencil in the manner indicated in Fig. l of the drawings, with the endof the foreiinger resting on the pen or pencil lholder andthe end of fthe middle finger pressing against the pen holder or pencil at one side, while the end of the thumb presses thereon at the other side, as indicated in Fig. ,1V of the drawngs, or use. The spring clasp will hold the attachment on the pencil or pen holder with the projecting arms in proper position to suit the person using the same, said arms 'having been previously adjusted and secured at the desired distance apart according `to the size of the hand to which the device is `to =be ,applied. The arm b fitting against'the palm ofthe hand, serves to restrain improper finger movement by preventing the iingers from drawing the ypencil or pen holder lengthwise toward 'the user, as is `the usual tendency, while the arm a, extending par- H f. tiallyacross and clasping thel back'oiv the hand `behind the knuckle ,of the index Viin-ger, serves to hold the device 5to the hand vand prevent movementv of thepencil orpen y' holder in the opposite direction, or away from the user. A correct position with the index and second Aiingers outstretched along lthe pencil, is thus obtained, resulting in a free'V wrist movement in writing and preventing 4the fusual cramping of the hand.
The device may :be used until vproficiency yin the practice of muscular movement has been attained, when 'it .may -be laid aside, unless the pupil desires to continue using it as a pencil or pen holder or rest for the hand.
It will be understood that the word pencil as used in the appended claims is intended to include either a pencil or a pen holder of any of the forms now in common use, or any other suitable device of a similar character used for writing.
The invention is susceptible of embodiment in various forms, and may be made of any suitable material, by stamping and bending, or swaging, or casting the two members each as an integral structure or in separable parts, riveted, welded, or otherwise secured together; but the device is preferably struck up out of sheet metal, aluminum, or steel, combining lightness with strength and resiliency of oneor both arms.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A device of the character described comprising a pair of arms having shanks of unequal length extending at an angle thereto, one shank being mounted luponthe ether and having a spring clasp extending therefrom adapted to embrace the other shank and a pencil ,or pen holder and securesaid parts together, the longer shank having a series of perforations therein, and a lug yor protuberance on the shorter shank adapted to engage said perforations for adjusting and securing the two arms at different distances apart.
2. A device of the character described consisting of a resilient arm having a shank extending there-from atan angle theretoand provided with a series of apertures therein, a second arm having a short shank resting upon the shank of the other arm and provided with a lug or protuberance adapted to engage said perforation@ the latter arm having a spring clasp extending from its shank adapted -to embrace the shank of said resilient arm and a pen holder or pencil -and secure the same andthe two arms together.
3. A device of the character described comprising a pair of arms having Shanks of unequal length extending at `an angle thereto, one arm being adapted to `set within the palm of Ithe hand while the other arm clasps the lback of the hand, each arm ha-ving amarginal bead toprotect the hand lfrom secured at different distances apart.
et. A device of the character ,described comprising an arm having a shank extending at an angle thereto and a spring .clasp integral therewith adapted to embrace a pencil and secure said arm thereon, a second arm having a shank extending at an angle thereto and perforated, the shank of the first-mentioned arm resting on said perforated shank and having' a projection engaging a perforation therein, whereby said clasp serves to secure the two arms together and to the pencil with provision for moving both arms along the pencil and securing them at any desired point..
5. A device of the character described comprising two members, one having an arm adapted to set within the palm of the hand and the other any arm for clasping the back of the hand, one of said members being provided with a shank having a series of apertures therein and the other provided with a protuberance adapted to engage the apertures in said shank for holding the two arms in a relatively liXed position with provision for adjustment; and means for attaching the device to a pencil and holding said arms in said relatively fixed position.
6. A device of the character described,
comprising a pair of arms having shanks of unequal length extending at an angle thereto, one shank being mounted upon the other and having a spring clasp adapted to embrace the other shank and a pencil or pen holder and secure both arms thereto; said Shanks having inter-engaging means for securing the two arms at different distances apart.
In testimony that I claim the foregoing as my own, I aiix my signature in presence of two witnesses.
