To allwhom t may concern.'

Be it known that l, JOHN FFLAHERTY, a citizen of the United States, and a resident of Toledo, county of Lucas, State of lhio, have invented certain new and useful llmprovements in Roll-Gauging Machines, of which the following is a specification.

This invention relates to gauging niachines and more particularly to machines for accurately gaging the taper of tapered rollers or bearings auditor asserting the rollers. @ne of the objects of the invention is to provide a machine of the class described w which will be capable of detecting ext-remewill be durable and with parts so designed that there will be a minimum amount of wear and this wear will not seriously ail'ect the continued accuracy of the machine.

Another object of the invention is to provide a machine lof the class described in which the rollers will be automatically ted into position to be gaged and, after being gaged, will be automatically assorted into the desired elassilication. I Other objects and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings, of which; 3o Figure 1 is a vertical sect-ion thru a machine embodying my invention, the section being. taken substantially on the line .1-1 of Figure 2; Fig. 2 is a plan view of the machine; Fig. 3 is a fragment of Fig. 1 with the addition of a section 01E certain parts as on the'line 3-3 of Fig. 2, the major port-ion of the gure being on the line 3 3 of Fig. 5:

Fig. 4 is a section on the line 4-4 of m Fig. 3;

Fig. 5 is a side elevation of` certain parts appearing inFig. 3 with parts broken away and shown in section;

Fig. 6 is an end elevation of the adjacent parts of Fig. 3; .and l Fig. 7 is a wiring diagram of the electrical portions of the mechanism.

Referring to the drawings, 10 indicates a base sectlon preferably in the form of a substantial and rigid housing adapted to be secured on a suitable foundation and to su port the upper section 11 which carries t e various mechanisms of which the machine is comprised. The housing section 11 has an upper wall12 at the center of which ly small variations in the taper and which there is a wall 13 forming a well which is substantially braced by radially extending ribs 14 which connect it with the outer wall of the section. The wall 13 has a hollow spindle '15 projecting upwardly therefrom onl which the table 16 is journalled by-means of the sleeve 17, the latten being substantially braced by suitable radial ribs 18. At the upper edge of the wall 13 therev is a seat 19 for an annular thrust bearing 2O which, as will be seen from Fig. 1, supports the table 16. This table 16 has an apron 21 which extends below and houses the bearing 20 and carries the gear ring 22 in which two sets of spur-

gear teeth

23 and 24 are formed.

-A vertical shaft 25, mounted in suitable` bearings in the housing sectionv11, carries at its upper end a pinion 26 which meshes with the

gear teeth

23 and 24 and is driven from a shaft 27, also suitably sup orted in the housing section 11, by suitable spiral or other gearing indicated at 28. The shaft 27 may be ,provided at its outer end with a pulley 29 by means of which it may be driven from any suitable source of power. Mounted on the to of the table 16 are the brackets 30 Whic carry the gaugin mechanism., From Fig. 2 it will be noted that I have provided six of the brackets 30 but it will be understood that more or less may be employed in accordance with the necessities of any particular case. Each of the brackets 30 carries a pair of cooperating verticaly

adjustable gauging members

31 and 32 arranged between suitable ways 33 on the bracket and. held in position by means of a suitable cover plate 34. At the lower end of the wa s 33 a cross-member 35 is secured by suita le screws 36 and carries the stationary gauging block 37 which is secured to the cross-member by a screw 38. The block 37 is provided with the gauging surfaces 39 and 40, at the bottom of a slot 39', which are adapted to contact with the end ortions of the tapered surfaces to be gage as is clearly seen in Fig. 3. The member 31 has a gauging surface 41 opposed to the surface 39 and the member` 32 has a gauging surface 42 opposed tothe surface 40, the surfaces 41 and 42 being at the bottom of a slot 41. A. lever 43, pivotally mounted in a suitableslot 44 in the member 31, has a knfe-edge on which rests the up-I. per surface 45 of arecess in the. member 32:4 The position of the lever 43 will therefore m recense the

members

31 and 32. A lever arm 46,

mounted on a pivot 47 between the ears 48 on the member 31, has a surface 49 adjacent the pivot 47 which is engaged by a knife-edge on the outer end of the lever 43. Thus the position of the lever 46 will vary in accordance with the position of the lever 43 and, on account of the relatively great length of the lever 46, as compared with the distance between the pivot 47 and the knife edge on the lever 43, it will be seen that any movement of theend of the lever 43 will be greatly mult1plied in the lever 46 so that the upper end of the lever will have appreciable movements for the almost imperceptible movements ofthe lever 43.

cross-member 50, on the upper end of the bracket 30, carries an adjusting screw 51 by means of which the tension of a spring 52 arranged. between the screw 51 andthe member 32, may be adjusted. 'lhere is a spring similar to spring 52, in cooperation with the member 31.

The member 32 carries a small lever 53 (see Fig. 4) which is similar to the lever 43 but oppositely arranged with reference to the latter and has a lmife-edge cooperating with a surface on themember 31 similar to the surface 45 on the member 32, and the outer end of the lever 53 has a knife-edge which cooperates with a lever 54, similar in all respects to the lever 46. rlhe member 31 has an upward extension which carries a contact member 55, preferably insulated therefrom in any suitable manner and with which the dexible lwire 56 is connected. A contact member 57, carried by the upper end of the lever 46, cooperates with the member 55 and has connected therewith a .Wire 58. ln a similar manner the member 32 has an upward extension which carries a Contact member y59 with which a contact member 60, on the upper end of the arm 54, cooperates, the member 60 having connected therewith a wire 6l. The wire. 56 is also connected with the member 59 so that, when these several members are in contact, a circuit .will be completed from the wire 58 thru the wire 56 to the wire 61. A coiled spring 62 lightly holds the

members

55 and 57 normally in contact and the spring 63 holds the members 59 and 60 in Contact.

The

members

31 and 32 have normally aligned recesses 64 inthe sides thereof with the upper surfaces 65 of which (see Fig. 5) a knif -edge on the lever 66 cooperates, this lever beine' mounted on a pivot 67 on one of -the ways 33. A cam lever 67 mounted between lugs 68 which project from the lower surface ot the cross-member 35, has one end connected with the lever 66 by means of the link 69.v

A pedestal 70 secured to the upper end of the spindle 15carries a pair of

contact members

71 and 72, which are secured to the pedestal by the screws 73, and are insulated from each other and from the pedestal as shown in Fig. 3. Associated with each of the `brackets 30 is a vertical pivot 74 on which the

levers

75 and 76 are mounted. The lever '75 carries a Contact member 77 which is insulated therefrom but adapted to contact with the member 71. The lever 76 carries a contact member similar to 77 which is adapted to contact with the member 72. The wire 58 is connected with the member .p77 and the wire 6l is connected with the corresponding member carried by the lever 76. By this means an electrical circuit is completed from the contact member 71 to the contact member 7 2 but, as will be readily understood, this circuit maybe interrupted by the separation of the

contacts

55 and 57 orthe contacts 59 and 60. A. pin 78 projects upwardly from the base of the braclret 30 close to the levers 75 and 76 (see Fig. 4) and leaf springs 79, carried by 'the

levers

75 and 76, engage these pins and normally press the contacts carried by the levers against the

contacts

71 and 72. The movement of the levers is restricted by the pin 78 as will be readily understood from Fig. 4 so that the levers are prevented from being thrownout of position when their respective contact members leave the

members

71 and 72.

The roller to be gaged is indicated at 86 in Fig. 3 and Fig. 5 and is normally pressed outwardly by a plunger 81 and aspiring-482 suitably housed in the bracket 30. The slots 39 and 4l' are slightly wider than the roller so that merely the downward pressure of. the

members

31 and 32 holds the roller in the position shown and when these members are lifted, as will be hereinafter described, the roller will be released and ejected by the plunger 81. 'lhe lifting or the

members

31 and 32 to release the roller is edected by a ca m 82 on the shaft 83. As will be seen romlrig. 5, the cam 82 is of Vgenerally cylindrical form with a dat surface 84. A torsion spri'n 85 is connected with the shaft 8.3 and t e bearingl 86 in which the shatt'fis carried and normally tends to rotate the shaft in the direction of the arrow in Fig. 5.

An arm 87 secured to the outer end of the shaft 83 cooperates with the core of an electro-magnet 88 which, when energized, holds the arm 87 in the position shown in Fig. 6. When the electro-magnet 88 is deenergized, the weight of thearm 87 and the series with the contact members 7l and 72 lill and a source of an electric current 90 by the wires 91 and 92. 1t will also be observed from this ligure that, when the contacts and 57 or the contacts 59 and 60 are' separated, the circuit, which includes the electro-magnet 88, will be broken thereby deenergizing the electro-magnet. 1f the roller to be gaged is of the proper taper, the

members

31 and 32 will have definite relative positions as will also the

levers

46 and 53 and the electric contacts will be maintained, regardless of variations in the size of the roller. If, however, the roller is not of the proper taper, the relation ofthe

members

31 and 32 will be change-d and one or the other of the sets ofcontacts 55

andl

57 or 59 and 60 will be broken. Thus it is possible to separate the rollers into two classes, one class being those of proper taper and the other class being those not having the proper taper.v

After the roller has been'positioned, as shown in Fig. 3, if it is of the proper taper, `the electro-magnet 88 will be maintained in the energized state and the cam 82 will have the flat portion 84 presented to the path of the free end of the lever 67 as the latter travels with the revolving table 16. As will be seen from Fig. 5 the lever 67 will pass over the surface 84 withoutl making contact therewith but, if the electro-magnet 88 is deenergized, the shaft l83 will have been rotated to present a high part of thc cam 82 to the path of the lever 67 and the end of this lever will, in riding up over this cam, actuate the lever 66 to lift the

members

31 and 32, thereby releasing the roller which willbe instantly ejected by the plunger 81.

After the roller has been ejected, a pin 93 on the periphery of the table 16, will engage w'th an arm 94 on the inner end of the shaft 83 and restore the parts to the position shown in Fig. 6, it being remembered that the arm 94 will be swung around from the full line position to the dotted line position in Fig. 5, when the electro-magnet 88 is (le-energized.

The mechanism for feed ng the rollers is claimed in my co-pending application No.

416,935, tiled October 14, 1920'and comprises a housing 95. secured to the housing section ,y 11 and carrying a hollow vertical shaft` 96`vr` within which is rotatable 'a shaft 97 on the'I upper end of which is the cam 98. The shaft 96 carr'es. at its lower end, a gear 99 which meshesv with the teeth 24 and the shaft 97 carries a gear 100 which meshes with an idler gear 101 and this idler gear, in turn, meshes with the teeth 23. The shaft 96 carries, at its upper end, a disk 102 having an upwardly extending peripheral flange in -which a seres of radial slots 103 are formed to receive the rollers.

A cover-plate 104 is secured on the housing 95 and extends over about one-half of the flange on the 4disk 102 as shown lin Fig. 2. The cover-plate 104 has a slot 105 thru which rollers vmay befed to the slots 103 and, when the rollers drop into these slots, they will be carried around in position to be ejected outwardly from the slots into the gauging mechanism.-

by the arm 106 which is actuated by the cam 98. The disk 102, b eing positively geared'to the table 16, will rotate -in definite relation to the tableso that one/of the slots 103 will be presented in alignment with each gauging meeha-nism'as it comes into positionl to receive a roller. lThen the roller is approaching the position where it is ejected into the gauging mechanism, the arm 106 will be retracted from the position shown in Fig. 2 under the influence of the ,roller has been properly positioned andthen the lever will run off the block 108 and permit the

members

31 and 32 to descend and grip the roller. Also just prior to the receipt of the roller by the gauging mechanism, the contact members, carried by the members 75 and 7 6, will engage the

contact members

71 and 72 and" thereby cause the electro-magnet 88 to be energized and hold the shaft 83 with the'parts inthe position shown in Fig. 6when the shaft has been turned by the engagementof the pin l93 with' the lever 94. lVhen the

members

31 and 32 grip the roller, if the latter is of the proper taper, the electro-magnetv 88 willv be maintained in the energized condition vand the lever 67 will not be actuated to release the I roller when it passes over the cam 82.- If, however, the roller is not of the proper ta- `per, the electro-magnet 8S will `be cle-energized and the shaftj83 will be turned, so that the cam 82 will trip the lever 67 after the pin 93 passes out from under the 1e-.

ire-r `Referring to Fig. 2, it will be seen that I 'have illustrated a chute 109 and the roller's having an improper taper will be ejected.

f jao into this chute and fall 'therefrom into any suitable receptacle 110, but the rollers 'which are of proper taper will be'carriedlaround until in alignment with the chute 111,'v when the lever 67 will be tripped by astationary block or cam 112. f v

The cam 112 isso positioned as to trip each of'the levers 67 -so that any rollers which "havcnotf been ejectedl into the chute.`

109, will' bee'i'ected into the chute 111.
