CALITERS.

To all whom z't maw concern present invention.

Be it knownthat I,` WILLIAM S. lVHrTE, a citizen of the United States, residing at Bedford, 'in the county of Lawrence and State of Indiana,have invented new and useful Improvements i'n Calipers, of which the following is a specification.

This invention relates to-improvemen't-s in calipers.

In carrying out the present invention, it is my purpose to provide a ipair of calipers wherein the legs may be adjusted vertically relatively to and independently of each other and which will be constructed in such manner that the ends of the legs will pass each other when such legs are swung relatively, thereby preventing one leg from in terfering with another.

It is also my purpose to provide a device of the class described, which may be used either as a compass or calipers, and which may be readily and quickly adapted .-for either use.

V`With the above and other yobjects in view, the invention consists in the construction, combination', and arrangement ofparts here'nafter set forth in. and falling within thescope'of the claims.

n the accompanying drawings;

.Figure 1 is a view in side elevation of a 'deviceconstructed in accordance with the Fig. 2 is ahoiizontal sectional view through' the clamp for the' legs of the device.

Eig. 3 is a. longitudinal sectional view through a pencil holder adapted to be used with one of the legs of the device when it is desired to use the same as a compass..

. Figs. 4, 5 and G are views of details of the invention. Y

Fig-7 is a view in side elevation of the compass leg.

Fig. 8 is a. perspectiveview of the pen `for use in connection'with the compass leg.

IReferring-now to the drawings in de-- tail, 1, designatesa clamp comprising main plates 2 and 3. having their corresponding inner ends lapped and placed in face to face contact' with each other and. formed with alinin ope'i'iinglgs .4, and their outer ends former across the inner faces withtransverse grooves 5 and with threaded openings 4 beyond the respective grooves. Overlying the grooved face of the plate 21s one 'end -of a companion or clamping plate 7 and the other end' of theplatc 7 is offset and Specification of .Letters Patent. Patented Aug, 14, 1917. Application led September 30, 1916` Serialv No. 123,100. I

'overlies the inner end portion of the other ii'iain plate 3,. while overlying the grooved portion of the plate?, is one end portion of a clamping plate 8 having Vthe other endv the plates. Passed through an opening 6" in the outer end of the plate 8 and threaded into the opening (i in the plate B .is a clamping screw 12, while passed through -an opening 6 iu the outer end of the plate 7 and threadedinto the opening (i in the plate 2 is a clamping screw 125. 14 and l5 desig- Inate respectively the legs ot the calipers and the ends of these legs are passed through the grooves 5 and heldfin adjusted position relatively to'eaeh other b vgueans of the

clamping screws

12 and 13, incident `to the latter drawing the plates 8 and `3 together and the plates 2. and 7 together, Y

' In practice, ,the

legs

14 and 15 maybe adjusted longitudinally of each other by loosening the clamping screws 12' and 13, and when the desired adjustment has been obtained, the clamping screws may be tightcnedso as to. clamp the legs against movement. By loosening the screw l0 the pairs of plates carrying the.

respective legs

14 and 15 may be swung so that the legsmay be swung relatively to eachother. Owing to the .lisposition of the groovedfaces of 4the plates 2 and 3, the legs 14an'd 15l are offset from' each other so that the' ends of tive swinging thereof, thereby preventing one leg from interfering with the other.

V16 designates-a pencil .holder having one end bifureated as at 17 and the legs of .the bifurcatedportion formed with alinig openings to receive a clamping screw 18 whereby the pencil may, be clam ed between thelegs as shown in Fig. 3 of t e drawing. The other end of the pencil holder-is bifurcated as at 19 and is adapted to receive a compass leg. The legs `of the bifurcated end '19 of the pencil holder are formed with openings that aline with .air opening l20 formed` in the compass leg to receive the such ylegs may each other in the rela- .prising two legs and a clamp clamping screw 2l whereby the pencil holder may he held upon the compass leg.

ln Fig. 7 oi the drawings, I have shown a compass leg which may be used in connection with the clamp in place of the legs of the calipers, and YWhen-the device is used as :i compass the pen Shown in Fig. 8 may he employed in connection with one of the compass legs, :is well es the pencil shown in Fig. 3A

Vhilc I have herein shown and described the preferred torni of my invention by Way of illustration, I Wishit 'to be understood that l do not limit or confine myself to the precise details of construction herein described und delineated, niodilication and variation maybe mede within the scope of the claims and `without departing from the spirit of the invention.

l. A device of the described oomhy which they are adjustahly coiniected, the clamp consisting of two pairs of gilaftes, the members of eaeh vpair being, spa ed .from each other at their inner ends at ,l pi'votelly interengitged with the members of the other pair the members of each pair at' their outer ends passing astride one arm, and Y. i ,ans for clamping the arm in ediristed pisition he tween them.

2. A. device of the class described comM prising two legs and e clamp by 'which they are adjiistebly connected, the clamp consist- :ing of tWo pairs 'of plates, the members of each pair being spliced from each other et their inner ends and interengaged with the members of the other pair zuid provided with inlined holes5 e eet screw passing through saidholee, the members of each pair et their outer ende passing aetride one arm, sind means for ehunping the erin in adjusted position between them.
