United States Patent O 3,192,629 ADAPTOR FDR SEERS Dewey H. Morrison, 2606 N. 15th St, Phoenix, Filed July 17, 1963, Ser. No. 295,680

1 Claim. (Ci. 33-23) This invention relates to an adaptor for scribers of the type employed in reproducing letters or characters from templates, and has as its primary object the provision of an adaptor by means of which a pencil, pen, or other Writing implement of conventional design may he employed with such scribers without the necessity of providing a special attachment shaft thereon.

A further object of the invention is the provision of an attachment of this nature which may be readily applied to any conventional scriber, particularly those of the type which normally grip a round shaft of a conventional printing tip or pen, which will readily accommodate any conventional pencil, ballpoint pen, fountain pen, or other standard or writing implement, and which may be applied to the scriber with a minimum of time, effort, and difficulty.

A further object of the invention is the provision of a device of this character which will securely retain the associated writing implement in a position whereby characters may be readily reproduced from templates.

A further object of the invention is the pr vision of device of this character which enhances the speed and accuracy of reproduction of characters from the template due to the fact that smearing ink may be avoided, the point of the pencil or pen is more clearly visible to th operator, and small letters or numerals may be produced readily and expeditiously.

Still another object of the invention is the provision of such a device which is sturdy and durable in construction, reliable and eificient in operation, and relatively simple and inexpensive to manufacture, assemble, and utilize.

Other objects will in part be obvious and in part he pointed out as the description of the invention proceeds, and shown in the accompanying drawings wherein:

FIGURE 1 is a top plan view of one form of conventional scriber and associated template showing the adaptor of the instant invention associated therewith.

FIGURE 2 is an enlarged top plan view of the portion of the scriber of FIGURE 1 showing the conventional method of securing the shaft of a printing tip therein.

FIGURE 3 is a side elevational view of the scriber and template of FIGURE 1 together with the adaptor of the instant invention.

FIGURE 4 is a longitudinal sectional view taken vertically through the attachment of the instant invention and the tip of the scriber as shown in FIGURE 1.

FIGURE 5 is a fragmentary view showing a modified form of adaptor; and

FIGURE 6 is a top plan view of an alternative form of scriber with an adaptor bushing therefor which enables the adaptor of the instant invention to 'be used.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Having reference now to the drawing in detail, there is generally indicated at 10 a conventional scriber which includes an elongated body 11 having at its rear end a tail pin 12 and an upper guide knob 13. The tail pin 12 travels along the longitudinal groove 14 of a conventional template 15 having letters or other indicia 16 cut therein.

The body has mounted thereon an adjustable arm 17 which carries a tracer pin 18, which follows the lettering or indicia 16 as the tracer is moved for reproducing the indicia. A clamp arm 19 is also provided having an adjusting screw 2%, beyond which is a clamping jaw 21 at the extremity of a longitudinal split 22, the clamping jaw being controlled by a clamping screw 23. The usual arm lock 24 and handrest 25 complete the assembly.

In the usual employment of the device the round portion 26 of the shaft 'of a standard printing tip or pen is clam-pingly engaged between the jaws 21 and held by means of the clamping screw 23.

The adaptor of the instant invention is generally indicated at St and includes a shaft 31 of a diameter substantially equal to that of the conventional shaft 26 previously described. At its upper end shaft 31 has fixedly secured thereto a collar 32 to which is connected an annulus or ring 33 of relatively large diameter, or of a diameter sufficient to surround the shaft of a. conventional ballpoint pen or pencil 34. A set screw 35 extends through a threaded bore in the-side wall of annulus 33 and is provided with a head 36 by means of which the pen or pencil 34 may be tightly clamped in position for reproducing the characters or indicia 16.

By virtue of this arrangement any conventional pen, pencil, or other writing implement of relatively large diameter may be readily employed in conjunction with a conventional scriber, without the necessity of employing a standard printing tip or pen, and the resultant use of specialized ink. Also, by virtue of this arrangement the cleaning and care of fine instruments such as drawing pens employing the usual rounded shaft may be completely eliminated.

FIGURE 5 discloses a slightly modified form of construction wherein a shaft 40 has fmed thereto a collar 41, from which a sheet 42 extends to an annulus 43. In this case the interior of the annulus 43 is provided with a downwardly tapered bore 44 of slightly lesser diameter than that of a conventional pen or pencil 45, the arrangement being such that the tapered tip 46 0f the implement seats within the downwardly tapered bore, and is held in position thereby. The operation is identical to that of the previously described modification.

FIGURE 6 discloses a modified form of conventional scriber generally indicated at so which includes a body 51, a tail pin 52, an adjusting arm 53 having a tracer pin 54- at the end thereof, a clamp arm 55 and a height adjustment screw 56, jaws 57 governed by a clamp screw 58 being provided at the end of the arm 55. This is a standard scriber, and is substantially identical in operation and use to that of the previously described modification except that the jaws 57 are larger for theaccommodation of different types of shaft of drawing tips. In order to adapt this device to use with the adaptor of the instant invention a bushing generally indicated at 60 is provided which includes a cup 61 having an outside diameter suitable for seating between the jaws 5'7, and an internal bore 62 of a diameter to accommodate the

shaft

31 or 40. An annular flange 63 surrounds the upper portion of the cup 61, and seats on top of the jaws 57. The use and operation of the device of this form of the invention is substantially identical to that previously described.

From the foregoing it will now be seen that there is herein provided an improved adapt-or for scribers which will permit the use of any conventional writing or drawing 9 a implement therewith, and which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.

I claim:

An adaptor for a scriber of the type including a clamping device for holding the round shaft of a conventional printing tip, said adaptor including a shaft of a diameter corresponding to a conventional printing tip, adapted to be engaged in said clamping device and extend upwardly therefrom, a collar having a periphery fixed to the upper end of said shaft, a ring having a periphery and defining an opening substantially larger than the round shaft of a 4 conventional printing tip, means tangentially connecting the periphery of said collar and the periphery of said ring whereby said ring extends in horizontally offset relation to said collar, and means associated with said ring for securing an elongated, substantially cylindrical, portion of a standard writing instrument therein.
