COMPASS ATTACHMENT FOR PENCILS.
SPECIFICATION forming part of Letters Patent No. 322,865, dated July 21, 1885.
Application filed November 15, 1884.
To all whom it may concern:
Be it known that I, CARL WERNER STUART, a subject of the King of Sweden and Norway, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Compasses; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side view of my device, showing the same upon a pencil and ready for use; Fig. 2 is a similar View of the device, showing it folded, with the pencil and the needle-point reversed. Figs. 3 and 4 represent, respectively, a back and front view of the device. Fig. 5 is a cross-section through line as x in Fig. 2; and Fig. 6 illustrates a modified construction of the device.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to compasses adapted to be carried in the pocket and to be used in combination with a lead-pencil, stylograph, fountain-pen, or similar marking device; and it consists in the compass attachment which will be hereinafter more fully described and claimed.
In the accompanying drawings, A denotes a tube or sleeve, made of metal or any other suitable material, and having a slit, B, running longitudinally from one end to the other. This tube is, by preference, about two and a half inches long, and is marked on one'side of the slit B with a millimeter-scale, O, and on the other side with an ordinary inch-scale, D; or any other scales may, of course, be substituted for these two scales, if desired. The tube or sleeve A is open at both ends, and is of such a diameter that it will fit closely upon an ordinary lead-pencil, (shown at E,) upon which it will be held by the spring of the ma terial of which the sleeve is made. Upon that side of the tube opposite to the slit is fastened a bracket piece, F, the projecting part of which forms ahinge, G, for the arm or leg H, which has a sleeve, I, at its lower end for the insertion of the reversible and adjustable (No model.)
needle J, which is held in the sleeve I by means of a set-screw or binding-screw, K. In the upper part of the arm H, where this Is hinged to the projecting bracket-piece F, is bored a hole or recess, L, into which one end of the needle J may be inserted when the instrument is not in use. The lower end of the arm H, which forms the sleeve I, is bent inwardly, as shown in Fig. 2, so as to he close up against the lower partof sleeve A, and thus bring the lower point of the needle up close against the pencil, so that very small circles may be drawn.
From the foregoing description, taken In connection with the drawings, the manner of using this device will be readily understood without requiring extended explanation. As the sleeve is open at both ends, the penc1l E may be adjusted forward and back in the tube so as to make it of the proper length; and by loosening the set-screw K the needle J may be extended to a corresponding length, so that the distance between the hinge G and the point of the needle will be equal to the d1stance between the said hinge and the point of the pencil E. The hinge-screw G has a small thumb-nut, 9, so that the hinge may be tightened after the arm H has been adjusted at the proper angle for marking a circle; and by loosening this nut the arm H may be folded flat up against the sleeve, and by loosenlng the set-screw K the needle J may be pushed with its upper end up into the recess L, or it may be reversed, with the point inserted into 8 5 the recess, after which the nut g is again tightened, so as to keep the parts in their closed or folded position. The pencil is then re versed by inserting the point into the sleeve, which will prevent the point from breaking when the device is carried in the pocket.
If desired, the sleeve A may be constructed with a reversible cap, M, as shown in Fig. 6, provided with an eraser, N; and the sleeve may be made without the slit or slot B, and in its place have a projecting boss, 0, in which works a set-screw, P, adapted to bear with its inner end against the pencil, so as to hold the sleeve in its proper position upon the same and prevent it from sliding up or down when the implement is in use. If a short pencil is used for writing, the arm H may be turned up at an angle of one hundred and eighty de- 2, so as to form a convenient handle, which may be still further lengthened, if desired, by extending the needle J.
When the implement is carried in the pocket, the needle J may be with drawn from its sleeve in arm H and reinserted in a reversed position, with its point projecting into the recess L, as shown in Fig. 2, which will prevent the point of the needle from catching in the lining of the pocket.
It is obvious that the construction of this device in its details may be modified in vari-- ous ways without affecting or deviating from the spirit of my invention. For example, the hinge F G may be constructed in many different Ways and in one piece with the sleeve; and, again, the arm H may be made hollow or tubular, to adapt the needle J to be inserted into it its entire length, or, in other words, by continuing the needle-sleeve from the lower end of arm H up to the point where this arm is hinged upon the tube or sleeve A, so as to form a sheath or Scabbard for the needle.
Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United States- 1. The combination, in a compass attachment for pencils or similar marking implements, of the tube or sleeve adapted to be fitted upon the pencil, the hinge at its upper end and means for tightening the same, the hinged arm having a recess adapted to receive either end of the needle, and the reversible needle adapted to be fastened adjustably in the arm, substantially as and for the purpose shown and set forth.
2. The combination of the slitted tube or sleeve A, open at both ends, hinge F G, having tightening-nut 9, arm H, reversible and extensible needle J and means for properly securing the same in the arm, substantially as and for the purpose shown and set forth.
3. The hereinbefore-described compass attachment for pencils or similar marking implements, consisting of a slitted spring tube or sleeve having suitable scales marked on opposite sides of the slit or'slot, and provided on one side with a projecting bracket having a hinged arm and thumb-nut for fixing said arm in its adjusted position relative to the sleeve, said arm provided with an extensible reversible needle adapted to be inserted with either end into a recess in the arm near the hinge, substantially as and for the purpose shown and set forth. I
In testimony that I claim the foregoing as my own I have hereunto'affixed my signature in presence of two witnesses.
CARL WERNER STUART.
