Pniqnonnnn..`

To all whom t may concern Be it known that I, ERNST LABHARD, a citizen of the Republic ofv Switzerland, and resident of Thalwill, in the Canton of Zurich, Switzerland, have invented certain new and useful Improvements in Penhold.- ers, of which the following is a specification.

This invention has reference to pen-holders and its object is to so construct the same that the sleeve usually provided for the reception of the pen is adapted to pivot about a pin mounted transversely of and within the holder. The inner end of the said sleeve is hereby connected with and under the control of a spring-blade also mounted in the holder and tending to press the pen against the writing surface. The pen,.when writing, may thus yield to any pressure and the writer is therefore not only enabled to write more smoothly but his ngers are also subjected to less fatigue than is the casek with ordinary pen-holders.

In the accompanying drawings illustrating two desirable forms in which my `invention may be embodied:

Fig. 1 shows a longitudinal section, partly in elevation, of the pen-holder according to the firstconstruction;

Fig. 2 shows a section through line 2-2 in Fig. 1, and

Fig. 3 is a longitudinal section, partly in elevation, of a modied construction.

Similar parts are designated by like reference characters throughout the several views and the specification.

Referring to Figs. 1 and 2, representing the first form of construction, 1 designates a holder of tubular shape, 2 the sleeve adapted to receive the pen 3, and 4f a pin mounted in and transversely of the holder and serving as a pivot for the said sleeve. The inner end thereof has secured to it a springblade 5 of which the free end 6 rests on the innerface of the tubular holder, the springblade hereby having the tendency constantly to press the front end of the sleeve 2 and consequently the' pen 3 against the writing surface. When writing, however, the pen may yield in the direction of the arrow, Fig. l, with the advantages hereinbefore mentioned. A pen-holder so constructed is adapted especially for use of persons suffering from writin'g-cramp.

According to the modified construction,

Specification of Letters Patent. I Patented Aug, 1x75, y19,22, Application meanovember 17,- 1921'. 'seii'ai No.l 515,831. l

Fig. 3t'he one end 8 of the spring-blade 7 1s fixed in the solid rear part of the otherwise tubular holder l, while the other and free end 9 projects into and engages with the sleeveQ pivoted at 4, the spring-blade here also tending to press the pen 3 againstl the writing surface. Between its ends 8 and l 9 the spring-blade 7 is made to rest on a pin 10 which is secured in a ring 11 yand mounted transversely thereof and of the tubular holder 1. The said ring is hereby made slidable on the holder and the latter provided with a longitudinally disposed slot l2 in such a Way that the pin 10 extending' through and guided by such slot, when the ring 1s adjusted in eitherdirection indicated by the double arrow, is caused to press more or less strongly against the slightly downwardly curved spring-blade 7 This springblade, which is thus arranged and caused to act in the manner of a lever, may therefore be adjusted so that its end 9 exerts a greater or lesser pressure against the sleeve 2. Y

It will be easily understood that the devices described could also be, applied in connection with the well known and different kinds of fountain-pens.

Having now fully described my said invention what I claim as new and desire to secure by Letters Patent is 1. In a pen-holder of substantially tubular form, the combination,` with the sleeve adapted to receive the pen, of a pin mounted l in and transversely o-f the front end of the holder and forming a pivot for the sleeve, and a spring-blade mounted inthe holder,

the front end of the said spring-'blade en-` gaging the inner part of the sleeve and tending to press the same and 'the pen against the writing surface, all as and for the purpose set forth;

2. In a pen-holder of substantially tubular form, the combination, with the sleeve adapted to receive the pen, of a pin mounted in and transversely of the front end of the holder and forminga pivot for the sleeve,

a spring-blade mounted in the holder and engaging the sleeve and tending to press the same and the pen against the writing surc face, and means to adjustfthe pressure of ed in and tensversely of the front end of the hoder and forming a pvot 'for the seeve, a spring-blade mounted in the holder and engaging' the sleeve on the one hand and being Xed in the rear part of the holder on the other hand, a second pin mounted transversely of the central pst-ft of the holdex` and forming a rest for the spring-blade, and means to adjust the saidvseeond pin in relation to the eprng-bladdell as and for the 10 purpose described and shown.

In testimony whereof I have hereunto set my hand inthe presence of two subscribing Witnesses.

ERNST LABHARD.
