' FASTENING DEVICE FOR WRITING UTENSILS SUCH AS PENCILS OR THE LIKE Filed May 1, 1931 Patented Dec. 29,1931

JACOBUS PAULUS vANeesrnREN, or HAARLEIQI, manner-marine FAs'rnNINe DEVICE non WRITING UTENS-ILS, soon PENCILS on THE LIKE Application filed May-1, Serial No. 534,408, and in" the Netherlands April 16, 1930.

The invention relates to a device for fastening (tying-up) a writing utensil, suchas a pencil or the llke, by means of a flexible string, wire or llke fasteninganeans, which,

after havin been unwound from a s fin actuated-drum, may be wound up again on said drum. f

By the known devicesoi? this kind a pull is exerted continuously on the pencil or penholder during writing via the fasteningmeans by the spring-actuated-winding-drum, which is very objectionable. I

The chief object of this invention is to overcome this disadvantage and with this object in view the invention consists herein, that a support for the writing-utensil is provided with a resiliently upwards pressed holder, which, when pressed downwards, makes a clamping-device for the fastening-means in- ZU operative, which device is such, that when the fastening-means is being unwound it lets same pass unobstructedly but thereafter clamps it tightly. I 7

If one wants to use the pencil or the like the fastening-means is unwound from the drum, whereupon it is immediately automatically clamped, so that a pull no longer is exerted on the writingaitensil, while whenthe pencil or the like thereafter is pressed on its holder, the clamping-device of the string or the like automatically is made inoperative, whereby the latter is wound up immediately.

The drawings represent by way ofexampie a constructional form of the fasteningedevice according to this invention. In the drawings the whole" device is arranged on and in a loose wooden block, on the upper face of which the pencil is put. It is, however, to be understood, that the device quite as well can 49 be arranged on or in all kinds of devices in which it is desired to haveca pencil or the like always ready at hand, such as in writingdesks, writing-money-chests, etc.

In the drawings: I

Fig. 1 is a side elevation,'partially a section, and Fig. 2 is a bottom principal part of the device.

a represents a wooden-block, provided with a recess 6. On the top-face of this block a 9 small cover-plank 0 is fixed, on which two mounted.

plan view of they string g, which is secured to the pencil, leads to the spring-actuated-winding-drum 7L, located in said recess Z).- This winding-drum k is known on its own and also inknown manner it is enclosed within a cylindrical box orflcasingywith an opening through which the string gextends; 2,

Further the clamping-device for thestring is located in the recess F) of the wooden block andsaid'device consists of a suitably bent plate flyover which the string runs and which is provided with two depending legs 70, between which a lever m, one arni of which is loadedby a small weight Z, is pivotally Said lever m further. is designed and arranged such, that when the whole device is in thenormal position, the lever with its arm, since the latter then is lifted a little.

' The other arm of lever m extends under the pencil-clip a, which-clip is movable upand downwards in a sleeve 71, arranged in a hole of the cover-plank 0 andin which a screw-spring 0 islocated, so that clip 6 is normally pressed upwards. An extension 10 of clip 6 extends right above and very near to but not in contact with the latter arm of lever m. I

It is clear now, that when the pencil has been used and the string is in the unwound position one can make the string wind up automatically by pressing the pencil in the clips (Z and 6, since clip 6 then presses the right hand arm of lever m downwards and consequently the left hand one moves upwards, whereby'the string 9 is released, so that by the spring-actuated-drum it is drawn inwards. v I On top of the. wooden blockhfurther is arranged a sleeve g, into which a penholder or the like can be inserted; it is clear, howloaded arm, assisted by the tension in the lift) ever, that this sleeve has nothing common with the invention proper.

Further in the bottom of the block an iron or lead plate r is fitted in order to hold the complete device, so that same, when the pencil is taken from its supporting place, better remains on the spot.

It is to be understood that the device illustratcd in the drawings only represents one of the many forms in which the invention can be embodied and actually represents such a form suitable to be used as a separate unit on writing desks and the like on which, if desired, it can be rigidly secured by means of screws or the like and that many alterations are possible within the scope of the invention as indicated in the claim, e. g. the small weight Z, which tends to draw lever m in the operative position in which it clamps string 9 between one of its arms and the suitably bent plate j, might be replaced by a suitable screwor other-spring performing the same action.

What I claim is:

Fastening apparatus for an intermittently used article, comprising in combination with a spring-actuated drum and a cord thereon attached to the article, means to normally clamp the cord, a downwardly movable holder for the article, and a spring to normally raise said holder, the said holder having means, active when the holder is depressed, to cause the clamping means to release the cord and allow the cord to be rewound upon the drum.

In testimony whereof, I have signed my name to this specification.
