.sleeve 2 and adapted to engage the ends 11 of levers 7 and advance the contact points 9 against thel pressure of spring 7', while the other end of the push-rod extends beyond the rear end of the carrier. A yoke 14 secured to the rear' end of the carrier by a sleeve 14 has an operating lever 15 fulcrumed therein at 16, said lever having lan adjusting screw 17 threaded therethrough and adapted to engage the rear end of the push-rod. The adjusting screw is held in position by a lock-nut 17. Secured to the rear end of the push-rod is an arm 18, the hub 19 of which has a pin and slot connection with a link 2O pivoted on the lever 15. An indicator 21 of well known form is carried by the sleeve 14', said indicator having an actuating plunger 22 projecting` therefrom in line with a contact-screw 18 threaded in the end of arm 18, which screw is held in adjusted position by a lock-nut 23. A
holding or stop ring 24 (Figs. 1 and G) which is adapted toengage the outer end wall of a bore to-be tested, is slidably mounted on the carrier 1 and has a pin 25 mounted therein, which pin, as the carrier is moved relatively to the ring, is adapted to engage any one of a series of annular grooves 26 cut on the outer surface of the carrier. The pin is yieldingly held in a groove by a coil spring 27 compressed between the head of the pin and`a screw 28 threaded into the ring.
In the modification shown in Figs. 2 to 1 the carrier 29 has a bearing sleev'e 30 (Fig. 3) mounted therein at its forward end, said sleeve having an enlargement 31 at its cutest` ring 33 having a complemental recess 31 is secured to the enlargement, the ring and enlargement forming a housing for a pair cf diametrically opposed slidable pins 35 having contact points 35 at their outer ends. These pins are normally held in retracted or inoperative position by leaf-springs 36 bearing against flanges 37 on said pins. A fixed bea-ring or centering ring 38 1s secured to the carrier adjacent the enlargement 31. The pins 35v are moved outwardly against the pressure of the springs 36 by a push-rod 39 from.
having a bearing in the sleeve 30 and formed with a conical point 40 at its forward end adapted to pass between and separate the 1nner ends of the pins. A yoke 41 is secured to the rear end of the carrier by a sleeve 41 and carries at its end an indicator 42 having an actuating plunger 43 projectingthere- An operating lever 44 is fulcrumed in the yoke at 45 and has a link 46 pivoted thereto, which link has a pin-and-slot connection (Fig. 4) with the rear outwardly projecting end of the push-rod 39. An adjusting screw 47 is threaded in the lever 44 and has a point adapted to engage the end of push-rod 39, the screw being held in position by a lock-nut 48. A contact-screw 49 is threaded in the lower arm of the lever 44 in alinement with the plunger 43 and is held in position ,by a lock-nut 50.` A freely slidable bearing or .centering ring 51 having an enlarged bearing flange 52 is mounted on the carrier. j
The modification illustrated in Fig. 5 is identical in all respects with the form shown in Figs. 2 to 4, except that a single contact pin 35 is used instead of a pair of opposed pins.
In the form shown in Figs. 7 to 10 the numeral 53 designates a carrier tube provided adjacent its front end with a fixed bearing or centering ring 54. lithin the frontend of the tube is mounted a vbearing sleeve 55 provided with an enlargement or flange 56 at its outer end, the sleeve, carrier and ring beingsecured together by screws 57. Diametrically opposed slots 58 are formed inthe enlargement 56, and levers 59 movable in said slots are fulcrumed on pins 60. The front ends of said levers are turned outwardly in diametrically opposite directions to form contact points 61, while the rear ends 62 of the levers are turned backwardly. The contact-points are normally held` retracted by a coil Spring 63 secured to the levers, their inward movement being limited by stop-pins 64 adapted to engage the levers adjacent their rear ends. A plunger 65 is slidably mounted in ,the sleeve. 55 and has a contact piece A66 pivotally connected to its front end at 66', ,which piece is adapted to engage the rear ends of levers 59 to advanceV the contact points against the tension of spring 63. The plunger is actuated by a push-rod 67 pivotally connected to its rear end at 67. the push-rod extending through t-he carrier 53 and beyond its rear end. The piv'ots'66 and 67 are disposed at a right angle to each other and form a universal joint between the contact piece 66 and push-rod 67. A
Abracket-arm 68 is secured to the rear end of the carrier by a sleeve 69, and fulcrumedon the arm at 70 is an operating lever71. The lever has an enlargement '72 Fig. `8) having a circular opening therein, and pivot an elongated opening 8() therein, and a slidable block 81 is adjustably secured-in said opening by a set-screw 82. rilhreaded in the block is a 'contact-screw `83 adapted to actuate the plunger 78 when the lever l71 isoperated, said screw being secured in adjusted position by lock-nuts 84. Freely slidable on the carrier 53 is a. second bearing or centering ring 85 coacting with the fixed ring 54 to properly locate the gauge ...in the bore to be tested, and said ring 85 has an enlarged bearing flange 86 at its vrear end adapted to engage the end wall at the entrance to the bore when the gauge is slid vin the latte-r. A holding or stop ring 87 is slidably mounted on the carrier inrear of the ring .85 and has av pin 88 mounted therein, which pin, as the carrier is moved relatively to the ring, is adapted to engage any one of a series of annular grooves 89 cut on the outer surface of the carrier. The pin isyieldingly held in' a groove by a coil spring 90 compressed between the head of the pin and a screwy 9lvthreaded into the ring 87. I
In use the gauge is inserted in a test bore or ring, the lever actuated to advance the contact points against the Wall thereofrand the indicator set at zero. The indicating means shown is common and forms no part y of my invention, and in this form the indicator is set at zero by rotating the dial while the contact points vare held against the test ring. Any other desired means for accomplishing the purpose may be employed. The gauge is thenr placed in the bore to be tested and advanced atcintervals, the operating lever being actuated at each Y stop and the variations from the te'st ring being noted on the indicator. f The gauge is also rotated in the bore and readings taken on different diametersv at the same interval to test the bore for variations from a. true circle at that interval and disclose their location. The holding 'or stop ring Yand grooves shown in Figs. land 7 provide means for advancing the gauge at regular or predetermined intervals. and it is obvious that they may also be applied to the forms shown in Figs. 2 and 5. The forms `shown in Figs. 2, 5 andr 7 are provided with a. freely slidable rear centering orv bearing ring, thelatter having a flange adapted to bear against the outer end Wall of the bore to be-tested. The form shown in Fig. 1 is Laieee intended to be used with a fixed rear supin Fig. 7, that unless the operating lever be made very rigid the application of undue pressure after the contact points are in engagement lwith. the bore, will tend to ilex or bend the lever, thereby'moving the contact-screw 83 and plunger 7 8 a further disv tance and producing a reading on the indicator in excess of the true one. This' diiculty is avoided in the forms shown in Figs. 1 to 5, the contact-screw 18 as shown in Fig. 1 being vcarried directly by an arm on the push-rod .and therefore unaiected by any bending of the` operating lever, while in the form shown in Fig. 2 the power from lever 44 is applied to the push-rod on one side of the fulcrum 45 while the contactscrew 49 is carried on the opposite slde of the 'fulcrum and is therefore unaffected by.
undue' pressure on the' handled end of the lever. i It will be seen that by theuse olV applicants lever operated construction the readings may be taken very rapidly, since the mere moving forward of the lever at once brings the contact points into engagement with thebore, and upon release of the pres' sure the spring-pressed contact points are at once withdrawn. Moreover by making the indicating means independent of the gauge operating means but-actuated thereby, the indicator maybe instantly set at zero while the contact points are pressed lagainst the surface of the object used as ar standard,
without any danger of varying the position' of the contact points in the operation. The positive or negative variations from a standard in the object to be tested may be thus accurately and very rapidly read directly fromA the scale on the indicator, and the gauge indicating means -may be instantly changed when another standard lis to bel `used for comparison. l Having thus-set forthpcthe nature of theinvention, what I claim herein is-V 1. In a gauge,. movable `contact means, positive means for -advancingand yielding means for retracting said movable means, said positive means includingn an operating lever, a separate indicating means, and
means controlled by the movement of said lever for actuating said indicating means.
2. In a gauge,I a carrier, means for properly positioning said carrier longitudinally` and transversely with respect to an object to be tested, a plurality of opposed contact K tween said means and indicator, including a hand-lever fulcrumed outside of said carrier at its rear end.
.4. In a gauge, a carrier, a plurality of ymovable contact points mounted in the car-` rier, ylelding means for retractmg said points, a movable push-rod adapted upon its advancement to advance said points, an operating lever for advancing or retracting said rod, and indicating means adapted to be actuated upon advancement of said rod.
5. In a gauge, a carrier, a centering ring thereon, contact points movable transversely of said carrier, a push-rod operatively associated with said contact points at one end and extending outside vthe carrier at Vits 'other end, an indicator mounted on said carrier and having a plunger, an arm on said push-rod having a contact pin adapted to engage said plunger, a lever fulcrumed on said carrier and having a link connection with said push-rod, and a contact-pin on said lever adapted to engage said push-rod.
6. In a gauge, a carrier, pivotally` mounted arms having diametrically opposed outwardly directed contact points, a fixed centering ring adjacent said points, a movable centering ring surrounding said carrier, actuating means for said arms extendin through said carrier, an operating lever ulgj crumed on said carrierl and connected to said actuating means, and means for indicating differences in the movement of said contact points. l
7. In a gauge, a carrier, a plurality of opposed contact points adjacent one end thereof, means whereby said carrier may be centered in a bore to be tested, means for determining the position the gauge will assume in the` bore to be tested including a movable stop with means for yieldingly retaining the same in any one of 'a plurality of predetermined positions on the carrier, manually operable means for separating said points to contact with the element to be gauged, and means for indicating differences in the movements of said points at the different positions.
In testimony,whereof, I have signed my nanie to this specification.
