5 Claims.

This invention has reference to a device especially adapted for use by draftsmen, and especially those engaged in the preparation of commercial art drawings.

Briefly the invention consists in what may be termed an inking pen especially adapted for use in inking a drawing after the same has first been made in pencil, and a further object of the invention is to provide a device of this character whereby the inking can be done in a more efiicient manner than is now possible where the ordinary common writing pen is used and to which resort is usually had by the artist or draftsman.

In actual practice it will also be found that the invention will be equally efficient when used either for inking in on straight or curved lines.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view of the de- Figures 2, 3, 5 and 6 are detail sectional views taken substantially on the lines 22, 3-3, 55 and 6-6 respectively of Figure 1. v

Figure 4 is an elevational View of the device taken at right angles to Figure 1, and

Figure 7 is a view of a group of striping disks, the disks being shown in edge elevation.

Referring to the drawings by reference numerals it will be seen that the device comprises .a frame including a member or arm 10 which is provided with an enlargement 11 at one end. Rising from the enlargement 11 is a handle 12 into the lower end of which is threaded a stud 13 that fits loosely in a central opening provided therefor in the part 11 of the member 10. It will thus be seen that the handle 12 is mounted for rotative movement about its vertical axis. The handle may however be secured against such rotation through the medium of a suitable set screw 14 as will be clear from a study of Figure 3.

At its free or forward end the arm or frame member 10 on one side'jthereof is provided with a longitudinal notch that accommodates the inking or striping disk or wheel 15. The disk or wheel 15 is provided with a hole to receive a bearing pin 16. The disk or wheel 15 fits neatly on and revolves freely on its bearingpin 16.

On the side thereof opposite to the notch 17 the arm or frame member 10 at its forward end is formed integral with the lower end of a standard 18 that rises vertically from the arm or frame member 10 and is provided at its upper end with a lateral pin on which is secured a member or head 19 overlying the arm 10, by a nut 19a.

The head 19 in its lower side is provided with spaced sockets or recesses 20 that accommodate the upper end of longitudinally tapered inking fingers 21. The fingers 21 are of suitable resilient material and at their lower ends are in lateral Wiping engagement with the striping roller or disk 15. Intermediate their ends the fingers 21 are connected by a stud 22 provided with a hand nut 23 which may be loosened or tightened as found desirable for regulating the pressure of the fingers 21 on the sides of the striping wheel or disk 15.

In use, and as thought evident, the disk 15 is placed at some point on the pencilled line of the drawings and the device moved therealong in either direction. The disk, as the device moves, is caused to rotate and the periphery thereof, coated with ink from the inking fingers 21, being in contact with the drawing sheet will cause an ink line to be impressed thereon, with the ink line superimposed over the pencil line. A numher of wheels, as suggested in Figure 7, and of the same diameter and construction, but of different thicknesses, to correspond with the different widths of the lines to be inked, are constructed or provided for the tool.

vHaving thus described my invention, what I claim as new is:

1. In an inking device for draftsmen, a frame bar, a handle rising vertically from the frame at oneend thereof, a striping disk rotatably mounted. on the frame at the end thereof remote from the handle, a standard rising vertically from the frame at the last named end thereof, and means mounted on the standard having a part in contact with the disk for applying a liquid to the disk, said part including a pair of spaced opposed spring fingers engaging the disk at opposite sides thereof.

2. In an inking device for draftsmen, a frame bar, a handle rising vertically from the frame at one end thereof, a striping disk rotatably mounted on the frame at the end thereof remote from the handle, a standard rising vertically from the frame at the last named end thereof; and means mounted on the standard having a part in contact with the disk for applying a liquid to the disk, said part including a pair of spaced opposed spring fingers engaging the disk at opposite sides thereof, and a device connecting said fingers intermediate their ends for drawing the fingers into intimate lateral contact with the disk.

3. In an inking or striping device, the combination with a frame, a striping disk rotatably mounted on the frame, a standard mounted on the frame having a lateral head, and a pair of resilient applicator fingers connected at one end with the head and having free ends arranged to bear against the disk at opposite sides thereof and in a manner to direct a fluid on to the periphery of the disk.

4. In an inking or striping device, the combinationiwith a. frame, a striping disk rotatably mountedon the frame, a standard mounted on the frame having a lateral stem, a head on the stem, and a pair of resilient applicator fingers connected at one end with the head and having free ends arranged to bear against the disk at opposite sides thereof and in a manner to direct a fluid on to the periphery of the disk, a pin extending through the fingers intermediate the ends thereof, and a nut threadedly engaged with the pin for drawing the fingers inwardly toward one another to vary the space between the free ends of the fingers in accordance with the thickness of the striping disk.

5. In an inking device, the combination of a standard, a striping disk rotatably mounted adjacent the lower end of the standard, and means for applying ink to the disk includingtspring fingers extending downwardly from the upper end of the standard and having lower ends engaging the disk adjacent the periphery thereof at opposite sides of the disk.
