ADJUSTABLE CALIPERS.
SPECIFICATION forming part of Letters Patent No. 762,971, dated June 21, 1904:.
Application filed January 2, 1904:.
1'0 all w/wm it may concern: 1
Be it known that I, WILLIAM K. H. VVoER- NER, a citizen of the United States, residing at Evansville, county of Vanderburg, and State of Indiana, have invented new and useful Improvements in Adjustable Calipers. of which the following is a specification.
My invention relates to calipers, and is particularly applicable for inside and eccentric dimensions.
Figure 1 represents my improved caliper in the position of taking the measurement, and Fig. 2 represents the caliper in position to be removed after the measurement has been obtained.
In the drawings, B represents the body of the tool, which is a metal tube. Into theupper end ofthis tube B is inserted a metal rod A, which is adjustable and which is held in place by means of a collar C, provided with a set-screw D. The lower end of B is threaded E, upon which threads is screwed a lock-nut F. The lower end of B is screwed into the upper end of G, which is a short metal rod and is secured by lock-nut F. Into the lower end of Gr, by means of a pin I, is hinged a metal rod H so adjusted that the upper end of H fits into the lower end of G and forms one continuous breakable red when in the position illustrated in Fig. l.
The upper end of the metal rod H has a raised shoulder J. In constant contact with said shoulder J is a flat piece of spring-steel L, which is secured to G by pin or screw K.
When it is desired to obtain an inside measurement, the caliper is inserted, the set-screw D is loosened, and the red A is shovedup until it comes in contact with the surface to be measured, the end of H at the same'time resting upon the opposite surface. Then the setscrew is tightened.
To make the measurement absolutely accurate, the metal rod G may be screwed upon Serial No.- l8'7,582. (N0 model.)
threads E until the proper result is secured and such result made permanent by tightening lock-nut F.
To remove the caliper, all that is necessary in my invention is to bend the metal rod H to one side and the caliper is then easily removed, and the spring L, pressing upon the shoulder J, immediately forces H back into its original and proper position.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a caliper, the combination of the rods A, and G, adjustably secured to tube B; the rod H, hinged into the lower end of rod G; a spring to hold rod H, normally in extended position.
2. In a caliper, the combination of the rod A, secured to tube B, in an adjustable manner; the rod G, secured to the opposite end of tube B, in an adjustable manner; the metal spring L, secured to rod G, at point K; a rod H,hinged into rod G, at pointI; the rod H, having a shoulder J, adapted to be constantly engaged by metal spring L. 3. In a caliper, the combination of a rod A, a tube B, adjustably secured thereto by a screw 1), through a collar C; the opposite end of B, being threaded and having upon said threads a lock-nut F; a rod Gr, said threaded end of B being screwed therein; a rod H, hinged into the opposite end of rod G; a pin I, to secure rod H, therein; said rod H, having at its upper end a raised shoulder J; a spring L, secured to rod Gr, by a pin K, and being in constant contact with said raised shoulder J. 1
In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
WILLIAM K. H. VVOERNER.
