Application May 3, 1938, Serial No. 205,749
My invention relates to sizing device calipers particularly those used in connection with internal surfaces.
It is .an objectv thereof to provide a oatlng 5 mounting for a caliper of this type.
A further object is to provide-resilient support members for the ieelers orV work engaging por tions of said caliper.
A further 'object is to provide means for withdrawing said feelers radially out of contact with the surface of the work when the work and wheel are separated and to cause said .feelers to move radially into engagement with work when said wheel and work are brought together in grinding position.
This caliper is an improvement over the single feeler type of caliper in that`it gauges the distance between opposite ,points on the surface being ground rather than the distance between the surface being ground and another ilxed sur face either on the work itself or on the machine.
It isv not aiected by irregular tion of the work because it moves with the work under such conditions. The only movement which is effective to control size is the relative movement of the feelers in response to an actual change in 4diameter oi the work piece. result is possible only when the feelers are per- -mitted to oat relative to the caliper frame.
Figure 1 is a front elevation of an internal grinding machine showing the sizing device in' operative position.
Figure 2 is a right hand end elevation, of my device with the parts in inoperative position.
-Figure 3 is an enlarged end elevation oi a por- .tion of my device.
In the drawings Figure 1, cates the bed of an internal of the type shown-in my Patent 2,088,682 grantedAugust 3, 1937. A` carriage I2 upon which is mounted a headstock I3 is slidably mounted for movement longitudinally oi said bed. Said carriage may be moved manually by means o! crank 50 or by power as disclosed in 682. A wheel base II is slidably mounted for movement transversely-meteor on a .bridge 20. which spans carriage I2. A face plate I4 rotatably mounted on said headstock'carries a chuck I5.v A work piece I5 is secured in said chuck. Attached to the left hand: side of bridge Ilis a bracket 2l upon -which is'mounted a caliperframe `22. A roller 23 is mounted onone end of an arm'24 which inturn is 69 in bracket 2l.4 A chain 2i attached to the end ofanother arm 1l also se 6 Claims. (Cl. 51-165).

ally restricted.
secured to a shaft has its lower end Feeler 45 is attached to a block 45 which in turn yis suspendedV from bracket 4,5 by parallel resilient strips 50 and 5I. BracketzIS is adjust- A nozzle 55 is inserted in block aand attached to a supply line 55 for air or other uid under An arm 51 on bracket 43 has asaw slot 58 which may be -spread by an adjustable member2 59. The lower portion of said slotted arm carries a member 60 which may be adjusted Vtoward or away from nozzle 55 by adjustable An arm 55 is pivoted at 55 to bracket 45. One end of saidarm rests on a ledge 51 on block 48. The other end rests on a dog 55 which is adjust- During a grinding operation the teelers 45 and 45 are held in contact with the surface of the work l5 by means of resilient strips 33 and 34,` and 50 and 5l. As the work approaches the desiredv size, nozzle 55 approaches member 6l 45 .and the iluid escaping from the nozzle is gradu- The eiect of this restriction is described in my Patent 2,001,447 granted Bliay 14, 1935, 'and will not be discussed here except to note that one of its functions in this case 50 may be to cause an 'axial' separation of the work and wheel as disclosed in my Patent 2,088,682. In this case the work carriage I2 moves to the left. Cam 3l on said carriage; permits roller 23 to drop and rotate shaft in a clockwise direction 55' cured to shaft 69. The otherend ofosaid chain is attached to a -rod 30 the function of which will be described later. A cam 3| maybe adjustably mounted on carriage I 2 for engaging roller 23 upon movement of the carriage to bring work 5 into grinding position and causing it to rotate on its arm in a counter-clockwise direction. i The caliper consists of the frane V22 from which is suspended a bar 32 by means of resilient strips 33 and secured to lugs 35 and 35 i respectively -on frame 22. The vertical position of said bar may be adjusted by means of screw 3,1. A rod 30 is slidably mounted in said lugs 35 and 36 and urged upwardly by a. spring 38 one end of which bears against lug 3 6, the other end against a collar 39 onrod 30. Upward movement of said rod is limited by a stop screw 40.
Said dog engages lever 65 and tends to rotate it about its pivot 66 in a clockwise direction. Theresult of this movement of lever 65 ls that bar 32 is moved upwardly against the resilience of f strips 33 and 34 to separate feeler 45 from the surface of the work I6. The end of the lever which rests on ledge 61 moves downwardly to cause feeler I6 to be separated from the work piece. Said feelerswill remain in this condition until the carriage is moved to the right to bring a new work piece into grinding position. Because of the retracted position of the feelers the work 4may be passed over them without interference.
However, as soon as cam 3| lifts roller 23 the above described operation will be reversed and the feelers will again engage the inside surface of the work.
I claim:
1. In a sizing device a supporting frame, a bar resiliently attached to said frame and having a movement relative thereto, a pair of brackets mounted on said bar, a work engaging feeler on each of said brackets, one of said feelers being resiliently attached to its bracket.
2. In a sizing device, a supporting frame, a bar resiliently attached-to said frame and having a movement relative thereto, a pair of brackets mounted on said bar, a work engaging feeler on each of said brackets, one of said ieelers being resiliently attached to its bracket and means for moving said bar in one direction and said due to the action -o'f spring 3l. Said spring resiliently mounted ieeler and means whereby a force applied at the other end of said lever results in a movement of both brackets in one direction to separate the rigidly secured feeler from the work surface and at approximately the same time a movement of the resiliently secured feeler in the opposite direction.
4. In a sizing device, a supporting frame, feeler members resiliently mounted on said frame for movement in one plane only whereby to maintain floating contact with a work piece, one oi said feelers being rigidly mounted and another being resiliently mounted respectively relative to each other, and means for moving said feelers toward and from each other whereby to engage or withdraw same from the surface of the work.
5. In a grinding machine for grinding the internal surfaces of cylindrical work pieces, a work support, a grinding wheel support, mechanism for effecting a relatlve`longitudinal movement of said supports for placing said wheel and a work piece in working position, a vsizing device on a fixed support separate from said work sup'- port and having a pair of resiliently mounted work engaging feelers located in alignment with said work, and means controlled by said longitudinal movement for urging said feelers toward each other until the work and wheel are in working position.
6.In a grinding machine, a bed, a work carriage slidably mounted thereon for movement toward and away from working position, means on said carriage for rotatably supporting a work piece, a sizing device having feelers for engaging the surface to be ground, resilient means for normally urging said ieelers in a direction to `engage the surface to be ground, other resilient means for holding said feelers out of work engaging position, and Vmeansl actuated in timed relation with the movement of the carriage into working position to render said other resilient means operative or inoperative.
