MlCROMETER-CALIPERS.
SPECIFICATION forming part of Letters Patent No. 517,073, dated March 27, 1894.
Application filed April 7, 1892. Serial No 428,120. (No model.)
To all whom it may concern:
Be it known that 1, JOHN D. SLOANE, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in Micrometer- Calipers, of which the following is a specification. Y My invention relates to micrometer calipers of the type in which one leg is slidable and rotatable with reference to the other, the caliper "points being offset from the axis of such rotation,the same being an improvement upon my prior patent on micrometer calipers, dated July 7, 1891, No. 455,644.
My invention consists in providing means for adjusting the'position of the point of the relatively fixed caliper leg to take the measu rement, and reading scales in connectiogtherewith for indicating the same, and als' in providing improved means for operating and adjusting the relatively movable caliper leg.
My invention further co nsists in the construction and combination hereinafter described and particularly pointed out in the claims. J
In the accompanying drawings forming part of this specification, Figure 1 is a side elevation of my improved calipers, shown in position'to take the measurement of a plate, and Fig. 2 is a side elevation of the same, the movable leg being turned away from the other leg in position for insertion through the hole in the plate, the barrel or sleeve inclosing the movable leg, being shown in longitudinal section. g
In the drawings, the frame A is made up I of the sleeves or sockets 2 and 5, having their axes parallel, and connected by the member 4. Arranged to turn and slide freely in the sleeve 2 is the caliper leg 3, having a milled head 7 for its more convenient operation. The other end 11 is offset, so that its point 12 is in alignment with the axis of the sleeve 5. The leg 3 for a short distance inward from the head 7, is screw threaded and provided with a set nut 8, adapted to be screwed down so as to abut against the end of the sleeve 2. Arranged in the chamber or socket 9 in the outer end of the sleeve 2 is the spiral spring 10, which abuts against the bottom of the socket, and the nut 8. The collar 13 fixed upon the leg 3 abuts against the other end of the sleeve 2, under the tension of the spring 10. This collar is provided-with the pointed screw 14 whichengages the recess or socket 15 when the leg stands in its normal position, thus holding it from rotary movement. Arranged i n the sleeveor socket 5 is the straight leg 6, which is threaded into the part 17 of the sleeve, so that its point 16 is in alignment with the point 12 of the other leg, when the latter is in its normal position. The leg 6 is provided with the milled head 18 which has a sleeve extension 19, inclosing and projecting over the part 17. Upon the part 17 is inscribed the scales 20, and upon the tapering end of the sleeve 19 is inscribed the micrometer scale 21. The constructionof this attachment for the leg 6 is not shown in de tail, since it is in common use and no claim is made upon it. The set screw 22 is threaded through the socket 5, so as to bear upon'the'leg 6 and secure it in adjusted positions, The leg 3 is held from lateral movemeiit'fpr'efei ably by means of the ferrule 23, secured upon the end of the sleeve 2, into which the collar 13 closely fits. This construction also prevents the pinching of the'fingers of the operatorbetween the collar and the end of the sleeve, and guards the interior of the instrument from dirt, which otherwise would work into the sleeve around the leg.
The instrument is used as follows: The plate or object 24 to be measured, is tapped with a small hole 25, slightly larger than the diameter of the leg 3. The leg 6 is then screwed outward by means of its head 18, to a distance greater than the thickness of the object to be measured. The nut 8 is then loosened and the leg 3 pushed outward by means of its milled head 7,until the point of the screw 14 is forced from the socket 15, when the leg is rotated to bring its hook 11 into the position shown in Fig. 2, when it can be inserted through the hole 25 as shown in Fig. 2. It is then turned back to the normal position, as shown in Fig. 1, the spring 10 drawing the leg inward and the screw 14 en tering the socket 15, the nut 8 being then screwed tightly against the end of the bar rel. The leg 6 is then screwed up into bearing contact with the plate, as shown, when the measurement can be readon the scales,
or the leg 6 being secured by the set screw 22, the nut 8 is loosened to allow the turning of the leg 3 and the removal of the instrument from the plate. The reading of the scales 20 and 21 can then be taken at leisure, the position of the leg 6 being retained by means of the set screw.
