MARKING TOOL.

This invention relates to a marking tool designed primarily for use by shoemakers for the purpose of laying out on the soles of shoes, the positions of? the nails to be driven into the soles thereby to insure regular spacing and, consequently, a better appearing finished article.

It is another object of the invention toprovide a simple and eflicient structure of this character which can be handled readily and on whichmay be mounted marking wheels of diiierent shapes or sizes to suit the work.

A still further object is to provide a tool in which the marking devices are adjustably mounted.

lVit-h the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed with out departing from the spirit of the invention.

In the accompanying drawings the pre ferred form of the invent-ion has been shown.

In said drawings, Figure 1 is a side elevation of the tool. Figure 2 is a top plan View thereof. Figure 3 is section on line 3-3 Figure 2. Figure & is aside elevation of a modified form of structure.

Figure 5 is a bottom plan view thereof. Figure 6 is a section on line 66 Figure 4:. Figure 7 is a section online 7-7 Figure 5. Reterring to the figures by characters of reference 1 designates a handle from which extends a shank 2 provided, at its outer end. with. a flat elongated head 3. 'Formed in this head adjacent the respective ends are threaded openings 4: in each of which is arranged a screw 5 having a. head 6 atone end.

These screws are insertable into the heads. from opposite sides respectively and each screw has a marking wheel 7 journaled upon that end thereof remote from the head 6. These marking wheels, which are in the form of star wheels are formed with mar ginal points 8 placed upon desired distances. As shown in Figure 1 one of the wheels 7 can be provided with a. greater number of points 8 than the other wheel. In both structures the points are equally spaced.

The projecting end portions of the head I constitute guides and in practice the screws 5 are adjusted so as to bring the wheels 7 tl'iedesired distances from the sides of the head. In other words the distances between the points of the wheel and the planes occupied by the sides of the head are equal to the distances at which the rows 01? nails are to be spaced inwardly from the margin of the shoe sole. 6 After the parts have been. adjusted the tool is placed with one of the ends of the head 3 against the side of the shoe sole and with the selected wheel 7 in contact with the bottom of the sole. The tool is then pushed or pulled along the sole, the head being kept in contact with the edge thereof. Thus the point 8. of the wheel will bite into the sole, and leave depressions regularly spaced from each other and equi-distaut from the edge of the sole. These depressions are designed to receive the nails used in attaching the sole.

Instead of providing the structure illustrated in Figures 1, 2 and 3, the tool can be constructed as illustrated in Figures 4 to 7 inclusive. This modified structure includes a handle 9 having a shank 10 extending therefrom to a substantially circular head 11. Extending radially from this head is a 6 guide in the form of a finger 12 the active face of which is preferably rounded as shown at 13 in Figure 5. A screw let extends through the center of and engages the head 11 and mounted for rotation on this screw is a disk 15 having spaced apertures 16. Any one of these apertures is designed to receive a holding screw 17 extending through the head 11 whereby the disk is held against rotation. Studs 18 extend from the disk 15 toward the head 11 and journaled on these studs are marking wheels 19 similar to the wheels 7 heretofore described. Both marking wheels are provided with points, the points of one wheel being spaced apart "greater distances than the points of the other wheel as will be seen by referring particularly to Figure 4.

A channeling knife 20 is fastened to and extends beyond the periphery of the disk 15, this blade being so positioned relative to the wheels 19 that it can be used for trimming the edge of a sole without interference from the wheel and the wheels can be used for marking or laying out the positions of the nails without interference from the blade.

In using the tool disclosed in Figures 4 to 7 inclusive the wheels 19 can be adjusted relative to the guide 12 simply by disengaging screw 17 from the disk 15 and then turning the screw 1% so as to shift disk 15 toward or from the head 11. can then be inserted into one of the apertures 16 so as to hold the wheels 19 at proper positions relative to the handle 9. For example if the channeling blade 20 is to be used for channeling the sole when the sole is to be sewed, the blade is brought to the position shown in Figure 4t and is adjusted so as to be supported at a desired distance from the guide 12. The guide is then placed against the edge of the sole and the tool moved around the sole with the blade 20 cutting into the sole at the desired distance from the edge. If it is desired, however, to utilize one of the wheels 19 for laying out the nail holes, the disk 15 is adjusted angularly until the selected wheel is brought to The screw '17 position at one side of the guide 12 whereupon the disk is held in place by the screw 17. Thus the screw can be used in the same manner as the one heretofore described.

W hat is claimed is A tool of the class described including a head, a guide portion extending therefrom for sliding engagement with one edge of the work, a centrally supported disk adjustably connected to and located at one side of the head a work eugaging derice carried by the disk adjacent the periphery thereof and means extending from the head for engaging the disk to hold it against rotation rela, tive to the head and maintain, the work engaging means in operative position.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures.
