BEAM-COM PASS.

SPECIFICATION forming part of Letters Patent- No. 734,014, dated July 21, 1903.

Application filed March 31, 1903. Serial No. 150,385. (No model.)

.To all whom it may concern.-

Be it known that I, JUsTUs A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut,have invented certain new and useful Improvements in Beam-Compasses, of which the following is a specification.

This invention relates to beam-compasses; and one of its main objects is to overcome the to objection of the unwieldiness of the beam.

In carrying out my invention I contrive to adapt a foldable rule for use as a beam-compass.

In the drawings forming part of this specification, Figure 1 is a perspective View of a foldable rule provided with adjustable and detachable sockets made according to my invention. Fig. 2 is a perspective view of a socket. Fig. 3 is a perspective of one section of a foldable rule, showing the rear side thereof and a socket in position thereon. Fig. 4 is a face view of a fragment of rule, showing the foldable point in full lines in working position and in dotted lines in position of dis- 2 5 use. Fig. 5 is a vertical section taken through the pivot at 13, Fig. 2. Fig. 6 is a view of a point having means for carrying a pencil. Fig. 7 illustrates the method of detaching the socket from the rule.

In the several Views like signs denote like parts. r

1 designates a foldable rule consisting ofsections, of which those numbered 2 and 3 are shown as opened out. The sections are connected end to end by joints 4t of a wellknown kind, which give the rule when extended a certain degree of rigidity, so that the same may be used for many purposes, as if made in one piece. The rule may be opened out as far as desired, and upon the extreme open section I place a socket 5 and upon the first closed section a similar socket, each having a point 6 projecting below the rule. The sockets are securely attached to the rule-sec- 5 tions, and hence it will be seen that the rule may be used as a beam-compass and that the length of the beam may be varied to any extent within the capaeity of the foldable rule. The socket attachment preferably consists of a sheet-metal plate 7, having at its upper edge two claws 8 and 9, which hook at 10 over the rear face of the rule, Fig. 3. Atits lower edge the plate 7 is provided with claws 11, which have detent portions or catches 12, adapted to snap under the lower edge of the rule. These parts 12 project rearwardly from the rule, and in order to detach the socket from the rule it is only necessary to press upon said parts 12, as illustrated at Fig. 7, whereby the socket-plate may be sprung out to the position indicated in dotted lines at A, Fig. 7, when the socket may be lifted from the rule. Upon the socket I pivot at 13 a sheet-metal point 14, said point and pivot having sufficient stability to enable the foldable beam-compass to be used to scribe curves in the ordinary manner. This point 14 when not in use may be turned up to the position indicated in dotted lines at 15, Fig. 4, where it lies facewise close against the socket-plate 7o 7, so that, if desired, the sockets may be left upon the rule, and when the sections of the rule are folded the points may also be folded, so as to be out of the way. Upon the point I form'a spring-arm 16, which is adapted to enter a notch 17, cut in the upper edge of the plate 7 between the claws 8 and 9, said arm 16 thereby forming adetent, so that the point is prevented from vibration upon the pivot 13. The arm is also formed with a lip 18, whereby it may be caught and sprung out of said notch, so as to enable the point to be turned to a position of disuse. If desired, a notch or depression, as indicated diagrammatically at 19, may be formed in the body of the plate 7, Fig. 4, to detain the point in its position of disuse and avoid the liability of the same accidentally projecting from the rule or beam. At the lower edge of the plate I form a segmental extension 20, which may be concentric with the axis 13 of the point and upon which the spring-arm 16 may ride as it turns upon the azgis 1 3.

Referring to Fig. 6, it will be observed that the point may carry a holder 21 for a pencil- 5 point or pen 22 and that this socket may be paired with a socket having a-point'14,if desired.

Stamped from the lower portion of the plate 7 and bent up therefrom is an index 23, Figs. mo

3 and 5, which projects beneath the lower edge of the rule and cooperates with the graduations 24, formed upon the rear face of the rule. By setting the sockets on the rule so that these indexes (which are in line with the points) stand opposite the proper graduations on the rule a curve of any desired radius may be scribed.

Variations may be resorted to within the scope of my invention and portions of my improvements may be used without others.

Having thus described my invention, 1 claim- 1. An attachment for a rule, consisting of a frame bent at one end to enable it to hook over the edge of the rule, and having at the other end a single bend provided with adetent for snapping under the opposite edge of the rule,
