Description

Patented Apr. 21, 1931 UNITED STATES PATENT OFFICE EDWARD o. nrnr'z, or JOLIET, AND THOMAS ,w. KLIIPFEL, OFCHIGAGO, ILLINOIS A TYPISTS HANn REST Application filed April 4. 1929. Serial No. 352,355..

This invention in general relates to attachments for typewriters and more particularly to a typists hand rest adapted to be removably attached to any typewriter of conventional manufacture. I

The object of the invention is to provide an attachment for a typewriter that will serve as a rest for the hands of the operator while manipulating the keys.

Another object of the invention is to provide a typists hand rest of the kind described with means adapting the device to be quickly attached and removed from the frame work of a standard typewriter.

Other objects and advantages of the in vention will appear more fully in the details hereinafter set forth, when taken in connection with the accompanying drawings, in which,

V Fig. 1 is a fragmentary plan view of a conventional typewriter to which an embodiment of our invention is attached;

Fig. 2 is a side elevational view of the parts shown in Fig. 1, with the rest plate and a portion of the typewriter cross bar in section;

Fig. 8 is a fragmentary plan View of a slightly modified form of the supporting means for the hand rest;

Fig. 4 is a sectional view taken on line 44 of Fig. 3, and

Fig. 5 is a sectional view of a modified form of the invention.

In the drawings wherein similar characters of reference indicate corresponding parts throughout the several views, A designates the frame of a conventional typewriter,

of which 10 designates a conventional universal keyboard, and 11 the spacingbar therefor. From the frame A project forwardly the downwardly sloping members 12 which are integrally joined by the front cross name plate bar 13 to which latter we attach our invention now to be described.

In the embodiment of our invention shown in Figs. 1 and 2, 14 designates a hand rest plate which has an arcuate sloping portion 15 and integral depending side aprons 16. The plate 14 is preferably provided with bolt openings through which are passed bolts 17, which also extend through openings provided in lugs or shelves 18 formed integrally with a resilient yoke or U-shaped member 19, the legs of the member 19 being clamp ingly engaged with the front or name plate bar 13. This form of our invention-is dis closed in Figs. 1 and 2. It will be observed that the hands of the operator may rest on the plate 14, while manipulating the keys therefrom, We have found this device particularly adapted to assist the operator in the so-called touch system which is now practically universal, in that it provides a fixed position for the hands from which the fingers may strike the keys.

In the form shown in Fig. 3, the support ing plate 14 for the hands is the same as that shown in Figs. 1 and 2. The support-- ing member 20, however, if desired, and as provided for in this form, is preferably at-- tached to the side rails or members 12 of the typewriter. The shelf 21 of the present wardly depending legs 23 of the body of the member in this instance, being clamping 1y secured to the side rails 12 of the type- Writer frame by bolts and nuts 24.

. InFig. 5, we have formed the plate 14 of the hand rest with a downwardly depending flange 25 at the rear, the hand rest being secured by passing small bolts, preferably of the type of cap screws 26, through holes provided in the flange 25 to a clamping U-shaped member 27 having an integral- 1y formed stud 28, the latter engaging in a recessed part 29 of the name plate bar 13.. In the form shown in Fig. 5, if desired, the clamping member 27 could obviously be formed integrally with the plate 14, To put the plate into position on a typewriter, it is merely necessary to press the legs of the member 27 over the name plate bar 13 until the stud 28 seats in a recess 29. The device is readily removed by merely spreading the leg on which the stud 28 is formed, after which the clamping member 27 and the attached plate may be removed.

As is well known, considerable fatigue is experienced by operators of typewriters, particularly those employing the touch system, by the general necessity of maintaining the hands in a comparatively fixed position While the fingers strike the keys. Our hand rest is particularly designed and adapted to aflord a rest for the hands of the operator, it being assumed that the hand be supported preferably in the neighborhood of the junction of the wrist with the palm. In this manner, not only is the operator greatly aided in the support of the hands and arms during many hours of the day, but is also provided With means that will aid in maintaining a correct brooding or hovering position of the hands over the keys, recommended by those skilled in typewriter technique.

It will be understood that the invention isv susceptible of considerable modification and variation, and that we have illustrated pre ferred forms only hence, we do not confine ourselves to the precise details of construction but reserve to ourselves such embodiments and variations as fairly fall within the scope of the appended claim.

Having thus described our invention, what we claimas new and desire to secure by Letters Patent is In combination with a typewriter having a frame adjacent the keyboard, of a hand rest comprising a substantially flat rest plate arranged to extend horizontally in advance of said keyboard at a level below the normal level of the typewriter keys, said rest plate also arranged to extend throughout the width of said keyboard to support the wrists of both hands of an operator, a clamping member secured to said rest plate, and means for attaching said clamping member to said frame.

In testimony whereof we have signed our names to this specification.

EDWARD C. HINTZ. THOMAS W. KLIPFEL.
