Specification of Letters Patent. Patented J 1y 1 Application filed. January 22, 1919. Serial No. 272,568.

To all whom it may concern:

Be it known that I, FERNANDO OSCAR JAQUES, Jr., a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Gages, of which the following is a specification.

Internal gages as heretofore constructed in one piece will in time wear. When Worn so as to destroy their accuracy, they are thrown away. This means an appreciable loss, as these gages are expensive and cannot again be made accurate. 1

My invention has reference to internal gages used for gaging the interior of cylinders, bores, etc., and more particularly to an improvement on my internal gage shown in my United States patent appllcation filed Sept. 9, 1918, Serial No. 253,228. Allowed December 21, 1918.

The object of my invention is to improve the construction of such an internal gage whereby, the means of adjusting the balls for wear is improved and simplified and a more rigid and accurate gage produced.

My invention consists in the peculiar and novel construction of an internal gage, said gage having details of construction, as will be more fully set forth hereinafter and claimed. 1

Figure 1 is a side view of my improved internal gage.

Fig. 2 is an end view of the gage, and

Fig. 3 is a longitudinal sectional View through the gage.

In the drawings 4 indicates a solid round oblong handle, 5, 5 hardened steel balls and 6, 6, internally screw-threaded ball retaining locking caps. The handle 41 has at one end the, external screw-threads 7 and a de pression 8 for a ball 5 and at the other end an internal screw-threaded bore 9. An ad justing member 10 has corresponding external screw -threads 7 a depression 8 and an externally screw-threaded stem 11 which screws into the bore 9 and is, after adjusting for accuracy, rigidly and positively secured in the adjusted position, by a pin 12 through the handle 4 and stem 11. Each of the ball retaining

locking caps

6, 6 has an open ball retaining end 13 through which a ball 5 protrudes a predetermined distance, the internal screw-threads 14 in screwthreaded engagement with the screw-threads 7" and is knurled on its outer surface for convenience in turning the locklng cap to lockthe ball in the adjusted position.

The adjusting for accuracy is done by adjusting the adjusting member 10 on the handle 4 in assembling the parts and after assembling and adjusting for accuracy, the adjusting member 10 is fixed to the handle 4: by the pin 12. When in use a ball wears so as to destroy its accuracy, the locking ca) 6 1s loosened, the ball slightly turned an the cap tightened, thereby locking the ball in the adjusted position. The gage now has again its original accuracy of a fraction of a thousandth part of an inch and this may be repeated an innumerable number of times.

.Having thus described my invention I claim as new i 1. A gage having a solid oblong handle, and provided with a depression at each end, a ball on each end of the handle and seated in said depression, a locking cap on each end of the handle, each locking cap having an opening through which a ball protrudes, said locking caps being in screw-threaded engagement with the handle of the gage.

2. A gage having a solid oblong handle with an externally screw threaded end, and provided with a depression at the end, a ball on the end and seated in said depression, a

the ball protrudes, said locking cap being in screw-threaded engagement with the adjusting member and means for locking the adjusting member, after adjustment, in the adjusted position.

3. An internal gage having a solid oblong handle 4:,and provided with a depression 8 at the end and eXternal screw-threads 7 at one end, a hardened steel ball 5 seated in said depression 8, said handle having at its opposite end an internally screw-threaded bore 9, a ball retaining locking cap 6 in screw-thread i engagement with the screw threads 7 and having an open ball retaining end 13 through Which a ball 5 protrudes, an adjusting member 10 having external screwthreads 7 and an externally screw-threaded 813611111 which screws into the bore 9, and

has an initial adjustment in said bore and,

10 after adjustment, is rigidly securedby a pin FERNANDO OSCAR JAQUES, JR.
