COMBINED CALIBER AND DIVIDER.

Application filed January 18, 1927. Serial No. 161,862.

It is within the province of the disclosure,

to improve generally and to enhance the util ity of devices of that type to which the invention appertains.

With the above 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, without departing from the spirit of the invention.

In the drawings Figure 1 shows in elevation a device constructed in accordance with the invention Figure 2 is an end view showingone ot the points extended laterally with respect to the arm;

Figure 3 is a section taken through the means whereby the points are held in ad justed positions.

The device forming the subject matter of this application includes a pair of calipers comprising arms 1 which are connected by a pivot element 2, the arms 1 having cylindrical ends 3 whereon are threaded nuts 4:, the nuts 4 having threaded bores 5 for the reception of the ends 3 of the arms 1. Slots 6are formed in the ends 3 of the arms 1 and in the srots 6 are mounted the wider ends of points 7, pivot elements 8 being mounted in the parts 3 and holding the points 7 in the slots 6 for swinging adjustment in a fixed plane. The points 7 have lateral edges 9 and an end edge 10 therebetween, the edges 9 and 10 cooperating to form corner angles 11. The longitudinal edges which determine the acumination of the points 7, are designated by the numeral 12.

The points 7 may be alined with the arms 1, as shown at 1 1. the nuts 4 being advanced to bear upon the end edges 10, thereby to hold the points in the positions stated. When the points 7 are arranged as shown at 1 1, the tool may be used as an ordinary pair of compasses or dividers. The points 7 may be made to extend inwardly, as shown at 15, or outwardly, as at 16, the nuts 1 bearing on the edges 9 to hold thepoints in the positions stated. When the points are located as shown at 15, the tool is adapted to be used as a pair of outside calipers, whereas, when the points are located as shown at 16, the tool may be used as a. pair of inside calipers. Not only may the points 7 be arranged in the three positions shown at 14, 15, and 16, but, also, they may be made to assume two other intermediate positions, by engaging the angles 11 in the bores 5 of the nuts 1, as

shown in Figure 3. Each point 7 has fivecost of a ball and socket construction is thereby avoided. The edges 9 are disposed at an obtuse angle with respect to the end edge 10 and with respect to the edges 12. The edges 9 are not located at right angles to the edge 10, and, therefore. when the end of the nut 4 engages either of the edges 9, as shown in Figure 1 of the drawings, the point 7 does not stand at right angles to the arm 1, but stands at an obtuse angle thereto, this detail facilitating the operation of the tool when it is used as a pair of calipers.

\Vhat is claimed is A. pair of calipers comprising pivotally connected arms, and points pivoted to the free ends of the arms respectively, each point having similar, angularly-related end edges, said edges defining cornerangles. and a nut threaded on each arm, each adapted to bear at its end upon one of said edges to hold its respective point in adjusted position, the nuts having threaded bores for the reception of the arms, and the corner angles being receivable in the bores of the nuts thereby to hold the points in still other adjusted positions.

In testimony that I claim the foregoing as my own, I have hereto afixed my signature.
