PENHOLDER.

Application filed March 11, 1922. Serial No. 542,975.

To all whom it may concern Be it known that I, JAMES JOHN Guns,

of 415 Cordova Street, in the city of Vanthe paper will result in the penpoint sliding. into the holder, that the attention of. the

writer be drawn to the fact that he or sh was using too much pressure. v

Adjustment is provided which Wlll allow the release to be set to give way at anydesired point pressure, such tension being un der the control of the teacher;

possesses but few parts, all of which are so designed as to give good wear and to meet the conditions which will be imposed by the individual use accorded to it by different children without getting out or order.

By my method of adj'ustingthe release, the pen can be arranged toprovide for the varying improvement made by the child and as such improvement takesplace and the pressure exerted on the pen point becomes 1ess,'so the tension can be reduced, until ultimately; the child attains the degree ofperfection in writing which is sought by theteacher. v

The essential parts of my invention are, a cylindrical pen body, enclosing a pen holder slidably mounted therein, a spring constantly pressing the pen holder against its release mechanism, a release mechanism,

.which is adjustable by the rotation of a threaded rod, all of which will be more particularly described in the cation in which:

Fig. 1 is a section taken longitudinally through the pen.

2 is a section showing the release mechanism.

Fig. 3 is a cross sectionof the release on the line 3-3 in Fig. 1. 7

Fig. 4 is a perspective of the release clip detached from'the pen.

following specifi- Fig. 6 "is a; perspective view actuating the release mechanism. 1'

.All the drawings are shown to a greater scale than full size.

1 represents the barrel of my pen holder. which is a tube cylindricalin'form having open ends, the nib. end has a thread 2, on its outer surface, approximately the mid-length of the tube is a transverse slot 3 and a further slot 4" which is rectangular inform,-

both-of which are cut through the side wall of the tube substantially asshown.

5 1s aspring cover tube having a partial closure 6. at-the nib :end such partial closure consisting of a washer like outer rim 7 and- 4 an inner rim .8 dished'to an angle of;approx mately 45 degrees from the plane of the mm, the bore of tube 5 being .inade'two separate diameters, the diameter of the nib The pen is simple in construction and:

end being equal to the bore of barrel 1 and the rear enddiameter being substantially the diameter of the outside of barrel 1, the rear end bore being threaded to. engage thread 2 of'barre'l 1.,

is slightly less diameter than the barrel to permit of perfectly: free endwise movement,

15 represents a spring in compression between rim 7 and shoulder 16 "to carry the holder 9 upwards through the tubel on a predetermined, pen point pressure being. at-

' '17 is a clip which substantially surrounds p a thepen barrel 1, having a tongue 18' pro- Figr5 is aperspective vie'wof the end of" "the-adjusting screw.

Clip 17 has a pair of spring legs 19 each of which terminate in a semi-spherical member 20 having their convexities opposing each other yet beingset apart as shown in Figs. 3 and 4, the legs 19' extend downwards through aperture 4.

I 21 represents in general my spring tension plate Fig. 2, in which 22 is the upper end bent back upon itself beyond an angle of 90 degrees to act as a dovetail to engage the undercut end of space 12, the opposite end of plate is split into three tongues the outer two represented by numeral 23 engage the corresponding extremity of space 12 to retain the plate in fixed position in the holder 9, the centre'tongue 24 projects downwards and is drilled for the accommodation of adjusting screw rod 27.

25 is a spring tongue preferabl pressed out of plate 21 and formed integrally with same to project above a longitudinally arranged rectangular slot which spring carrie's a wedge shaped block 26 the sides of which taper towards the top and is disposed when in writing position in close contact with the convex surfaces of the semi-spherical members 20.

27 is a rod with a thread 28 out upon its inner end and which is squared at its outer end 29 for rotation by means of a key, 30 is a groove encircling the rod adjacent its outer end.

31 represents a T block slidable endwise along plate 21 its vertical leg extending downwards and being drilled and tapped for engagement by the thread 28 of rod 27 which on rotation causes the block to raise or lower spring tongue 21 as desired.

32 represents a slotted plate which is inserted transversely into slot '14 of holder 9 engaging the groove 30 on rod 27 to prevent endwise movement of said rod.

Having described the various parts of my invention I will briefly explain its operation and use.

The rod 27 is rotated by a key to raise or lower the wedge block 26 into proper engagement with convex surfaces 20.

On greater pressure being applied through the pen barrel 1 to the paper than that which the pen is adjusted for, the tapered shoulder of holder member 9 exerts a slight sliding tendency against inner rim 8 of spring cover 5, which in conjunction with the pointwi'se pressure of the hand is sufficient to cause wedge block'2'6 to spread the legs 19 of clip 17 apart to allow its passage through the gap, the holder member 9 is then carried upwardly along the barrel 1 by the coil spring 15 the upward travel of holder 9 being stopped by tongue 18. The pen can be readily taken apart by simply springing clip 17 off the barrel 1 and withdrawing holder 9.

It v'vi-llthu's be seen that I have devised a pm which is capable of the finest adjust ment and which is not liable to damage through the abuse to which it may be subjected by children.

That it will enable a child to use a pen without exerting undue pressure upon the pen or paper and by which the difficulties in teaching handwriting will be largely overcome.

What I claim as my invention is:

1. A pen holder for the purpose described having a barrel, a pen holding member slid ably mounted therein, means of resiliently retaining the pen thereof in normal writing positionand means oi automatically releasing and retiring the pen into the barrel when a predetermined pressure is exerted pointwardly' of the barrel and means of adjusting the releasing mechanism.

2. A pen holder for the purpose described having a barrel with a spring cover extension thereto, a pen holding member slidably mounted within the barrel, a coil spring engaging the cover extension and the pen holding member, means of resiliently retaiining the pen thereof, in normal writing position and means of automatically releasing and retiring the pen into the barrel when a predetermined pressure is exerted pointwardly of the barrel and means of adjust-- ing the releasing mechanism.

3. A pen holder for the purpose described having a barrel with a spring cover extension, a compression spring therein, a clip member removably sprung upon the barrelhaving aton'gue projecting through the side wall of the barrel to limit the sliding movement of the pen holding member, said clip member having a pair of spring legs projecting towards the transverse centre of the barrel, which legs terminate in semi-spherical knobs for releasing engagement with. an adjustable wedge block mounted upon a spring, a block slidably movable under said spring, having screw rod means of positionin'g same for the 'tensio'ning of said spring, and key means of retaining the screw rod in endwise position and means for rotating same.

A. A pen holder forthe purpose described having a barrel with a spring cover exten sion, a pen holding member slidably mounted within the barrel. a spring engaging the spring cover member and the pen holding member. means of limiting the travel of the pen holding member within the barrel, means for retaining the pen in normal position and automatic means of releasing and position and automatic means of releasing wlthln the barrel when a predetermined pressure 1s eX- and retiring the pen endwise erted pointwardly of the barrel, screw means of adjusting the releasefor any, desired I pressure, means of retaining'the screw rod in fixed endWise position within the .1 pen 5f holding member and means or" rotating said screw rod. 7 d
