Description

UNITED STATES PATENT OFFICE.
GEORGE D. MOLANE, OF PROVIDENCE, RHODE ISLAND, ASSGNOR TO DARLING, BROlVN & SI-IARPE, OF SAME PLACE.
CALIPER-RU LE.
SPECIFICATION formng part of Letters Patent No. 477,183, dated June 14, 1892.
Application filed October 6, 1891. Serial Na. 407,936. (No model.)
To all wiz/m it may ooncern:
Be it known that I, GEORGE D. MOLANE, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Caliper-Rules, of which the following is a specification. i
My invention consists in an improved device for fastening the caliper-slide in any desired position, as hereinafter fully set forth.
Figure l represents a side View of a caliperrule provided with my improvement. Fig. 2 represents a transverse section taken in the line w a: of Fig. 1. Fig. 3 represents a longitudinal section taken in the line y y of Fig. 2. Fig. 4C represents a transverse section as in Fig'. 2, showing a modification.
In the accompanying drawings,A represents the body of the rulc, and B the ealiper-slide, which is provided with the ordinary graduations, and within a recess c, made in the body A, is placed the gib b, which is adapted to bear against the edge a of the slide B, and upon the Stud (Z, which maybe either` provided with a screw-thread e or be made smooth, as shown in Fig. 4, and within the slot-opening made in the body A is placed the tightening-wheel g,which is provided at its forward end with the central projection h and a central openngj, adapted to receive the stud d, the said opening either being, as shown in Fig. 2, provided with a serew-thread adapted to [it the screw-thread e of the stud orsmooth and loosely fitting the stud, as shown in Fig. 4, and in Ithe latter case provided with an in clined rear surface e', by means of which a forward movement will be imparted to the wheel g upon turning the same in the proper direction, as would be the case of the screwthreaded Wheel shown in Fig. 2, the said inclined surface being caused to bear against the side of the slot-opening in which the wheel is placed. When the wheel gis turned upon the stud (Z to produce a forward movement, the gib b will be pressed against the edge a'of the slide B to hold the same securely in position, and when the wheel g is turned in the opposite direction upon the stud (Z the slide will be released from pressure, so that the said slide may be moved to any desired position, and the stud d may be held from turning with the wheel g by means of the transverse pin z' or otherwise.
I claim as my invention-- 1. The combination, with the body of the rule, provided with a transverse opening, the ca1iper-slide,and the fixed stud arranged withn in the transverse opening, of the tighteningwheel arranged upon the stud, substantially as described.
2. The combination, With the body of the rule,provided with a transverse opening, the caliper-slide, and the fixed screw-threaded stud arranged within the transverse opening, of the tightening-wheel provided with a screwthread which fits the screw-threaded Stud, substantially as described.
GEORGE D. MCLANE.
