The invention relates to drawing implements, in particular a drawing implement for drawing or writing characters in accordance with a template that guides the writing implement
and of the type described in U.S. Patent
2 011 195 is shown.

So far, writing implements guided by templates have been used and old clamping devices have been provided to secure a writing implement, such as a pencil or a pen, in the installation position. However, the clamps have not Proven satisfactory as they did not use the writing instrument

hold securely in position and the hem devices are in place also difficult to operate due to the small screw head, which in turn is necessary in order to obstruct the view of the Avoid working documents.

Furthermore, there is no satisfactory device for holding the writing instrument between the periods of time it is ^ Turn, and the draftsman must carefully place the writing instrument on a suitable surface or on a piece of scrap paper take off. In each pail, it is difficult to prevent the ink from flowing out, and it is a satisfactory solution unavailable.

One object of the present invention is to provide a To create writing implement that avoids the problems highlighted above.

™ Another goal is to provide a clay device which has a mechanically advantageous hoboJfi system to To keep writing utensils in bin position "

Another object is to provide a hand-operated spar or leg to separate the writing material from the support surface to lift while at the same time releasing it from

Reference will now be made specifically to the drawings. The writing implement has a lower part which has a generally rectangular plate 10 which in turn has fairly equal angles between a short edge with an extension 11 along one side which extends away from the short edge. The port set is provided with a writing utensil receptacle 12 for accommodating writing utensils, such as a tubular spring 13 with a storage container. A relatively flat rear rod 14 halves the angle formed by the sides next to the short edge and is fastened perpendicular to the plate 10 by means of fastening screws 15, which are loosely taken up by drilled openings 16, 16 in the base plate 10 and are screwed into threaded bores 17ι 17, which in turn are worked out in the front stepped part of the rear rod Ik , whereby a rigid style is created.

Bin Bndstift 18 contains a threaded bolt 19 with a hexagonal head 20 which is screwed into an extension 21 on the rear part of the side rod Ik so that the pin 18 can be guided in the longitudinal groove of a template. Bin characters-driving pin 22 is attached to an arc-shaped adjustable arm 23, which is pivotably mounted on a bolt Zk and is clamped in the set position by a knurled nut 25, which in turn cooperates with a threaded bolt 26 in the usual way, around the

One side of the plate IO and the extension 11 is provided with a recess 27 which receives a lever and which receives the sections 28, 28 A of the clamping levers which also have flanges 29 and 29 A projecting upwards and downwards. The clamping levers are pivotable in the recess 27 by means of a dowel pin 30, which extends through aligned, pin-receiving openings 3.1, 31 and 31 B in the levers and in the extension 11. The rear ends of these levers are pressed outwards away from the plate by a compression spring 32, and the spring 32 sits loosely in an opening 33, whereby the rear ends of the levers are pressed outwards and you are in front of the bearing pin; 30 lying ends of the levers were turned inward, so that the recesses 34, 3 ^ A in the planes encompass the cylindrical part of the writing utensil 13 and borulate them. . do is to secure writing materials effective in adjusting position, is 75s noticed _t the material of the lever spring is>, u; ul that ciin jorter lever writing materials effective Berühr :, d ", the compression spring 32 is sufficiently strong to the lever within iliror To bend the elastic limit partially and hold the lever individually in resilient engagement with the writing utensils; see below.

tool effectively secured in the installation position while at the same time thereby a release of the writing utensils is enabled that the rear codes of the levers are moved against the plate 10, lin lifting lever 35 »which has a curved one at one end handle 36 and an angled handle 37 at the other end and its connection sub-section has a main section

38 and comprise an angled protruding section 39, a pin 40 is pivotably mounted, which passes through the opening 4l next to the handle 37 and protrudes into the pin-receiving opening 4l in the rear end Ik . The leg 36 extends through the opening 42 in the plate 10 which accommodates the start lever, whereby the foot of the on etellhebels 36 protrudes above the plane which is delimited by the tips of the writing utensils 13, the end pin 18 and the driving pin 22. As a result, the writing instrument with the writing utensils can be kept out of contact with the drawing, because the lever is in the position shown in Figures 4 and 6, the dashed lines in Figure 6 show the inoperative position of the positioning lever when the writing instrument used to draw letters or numbers.

To keep the deployment lever in its extended position and in its inoperative position, a Z-shaped one is used Spring with a fastening portion 43, a spar 44 and a Reibabsohnltt 45 by means of their section 43 on the

A screw 46 is attached to the reduced forward-raging end of the rear rod, which passes through an opening in the section 43 of the Z-shaped spring and is screwed into a threaded bore 47. The spar 44 extends over the reduced end of the rod Ik and protrudes beyond this so that the spar 44 comes into contact with the upper edge of the lever portion 39 when the deployment lever is in its working position. The section μ 45 of the Z-shaped spring, on the other hand, comes into contact with the side of the lever in order to hold the deployment lever in its raised position by friction, which ensures partial locking of the deployment lever and avoids any risk of leg 36 being unintentionally withdrawn will. Recesses 48, 48 A are provided in the clamping levers in order to create a distance from the installation leg 36 in all of its setting positions. Threaded bores 49 and 50 are provided to accommodate the spacer screw 51, whereby the desired distance between the writing tip of the writing utensils can be set, especially if the writing utensil consists of a spring, in order to avoid excessive pressure between the writing tip and the paper. Matching oversized openings 52, 52 A and 53 »53 A are provided in the sections of the clamping levers to provide the correct clearance for the spacer screw 51, regardless of which threaded hole is used.
