My invention relates to gauging machines, particularly such as are adapted for gauging the diameter ofconical pieces, such as taper rollers for roller bearings'. The inventionvhas for its principal object a machine j which is quick and accurate in operation, which requires only a maximum and mini'- mum setting for the entire range of sizes covered by themachine, the intermediate sizes being automatically cared for, which can be very easily adjusted to work of different sizes and tapers and which has a very simple and accuratesorting device. i

The invention consists principally in providing a size4 gauging machine with a single gauging station which operates a single contact lever, and electrical y connecting a plu- 4rality of dischargegatesy with contact members arranged to contact with said Contact lever. I The invention further consists in an inclined' sectional discharge chute and means actuated by the work-being gauged for raising the several sections of said-discharge chute. The invention further consists in the gauging machine and in the parts and combinations and arrangements o parts hereinv after described and claimed.

meshes with a worm 5 on a drive shaft 6 that is mounted in the base. Said drive shaft 6 is rotated in any suitable way as by a pulley wheel 7 and is preferably provided with a friction clutch 8 to permit the parts to slip,

,if necessary, to avoid injury'to the machine.

Said worm gear 4 is loose on said cam shaft 3 and is provided with a clutch member 9 adapted to mesh with a cooperatin clutch member 10 keved on said cam sha 3 and provided with an loperating-handle 11 by means of which the two clutch members ma be engaged or disengaged. Said cam sha 3 is also provided with a hand wheel 12 by which it may be rotated.

Said camJ 'shaft 3 1s rotated by a worm gear 4 .that

A gauging seat member 13 (Figs. 4,8, 9 l

and 10) is slidably mounted in the base and has a roll receiving member 14 secured to the end thereof as by means of an internally threaded cap 15 litting over said roll socket' member 14 and screwed onto the threaded end of the seat member 13. The tapered socket of said socket member 14 has the same taper' as that of the rolls 16 being gauged.

Said slidable gauging seat member 13 has va floating contact block 17 `(Figs. 8, 9, 10

*and 12) secured to the end opposite the roll receiving socket member 14. Said contact block 17 contacts with a lever 18 that is pivotally mounted in a housing 19 its pivot pin 20 having centers in its ends fitting over pivot studs 21 in said housing. Said housing is provided with a supporting frame 22 that has a slide portion 23 fitting in a slideway 24 22 and lever housing 19.

Said level 18 is provided with a sector 26 at .its free end that meshes witha sector 27 that is rotatable on a'hollow rotatable pin 28, 'a

bushing 29 (Fig. 9) being interposed` between said pin 28 and the bore-of the sector 27 .v Said pin 28 has conically bored end portions that receive the conical 'ends of pivot Said sector member has a projecting end portion 33 engaging thev lower end of said open lever32. A bifurcated spring -34 securedI to said sector vmember by a screw 35 engages the upper end of said open lever 32 causing said lever and said sector, member 27 to move as a unit under normal conditions. On the upper endlof said open lever 32 is a gear sector`36 meshing with theteeth of a inion 37 secured to an indicator arm 38 t at is mounted on a pin 39. Said pin 39 has conical recesses in 'its ends receiving vpivot studs 40 (Fig. 10) that are mounted in said housing 19 f Secured to a bracket member 41. (Figs. 3, 7 and 9) on said housing 19 is a stud 42 on which a sleeve 43 is rotatably mounted. An arm 44 projecting from said sleeve 43 is connected to a link 45 that is connected to said indicator lever 38. Secured to the outer end of said stud 42 is a collar .46. A spring 47 coiled around said .sleeve has one end secured to said arm 44 and the other end secured to said collar 46. A .bracket 48 is secured t0 the housing by screws 49. To the outer end of said bracket 48 is secured a stop member 50 for said lever, as by a bolt 51 and nut 52. To the lower part of said housing a similar bracket member 53 is secured by a screw 54, said lower bracket 53 also having a stop member 55'secured thereto b a bolt 56 and nut 57. Obviously a roll 16 w ose taper is .the same as the socket of the roll socket member 14 .will project from said socket member a distance depending on its mean diameter; and

f respondingly different ,positions of the indicatorlever 38.

The rolls 16 are fed into a feeder tube 58 from a hopper 59 by any suitable device, such as that shown diagrammatically in the draw- I ings (Figs. 1, 5 and 7 )a `As shown in the said cam shaft 3. Said cam lever 66 has a bushing 69 at its pivot and on the pro'ecting portion of this bushingis mounted t e hub ortion of an extension 70 of said lever 66.

aid level"` 66 has a projecting portion 71 in which is a slot 72.. Said lever extension 70 rests againstsaid proj ecting portion 71 of said lever 66,' extendlng beyond the end thereof, and is secured thereto by meansof a screw 73 extending through said slot 72 and into a threaded 'hole in said leverextension 70. Said pin 65 has a collar 74 thereon that bearsagainst said lever extension 70. Said lever Iextension 7 0 has a transverse slideway 75 in its end and the bottom 'of said slideway is provided with a slot 76. A block 77 has a portion tting in the slide portion of said lever extension 7 0 and is secured in place by means of a screw 78 extending through said slot 76 and into a threaded hole in said block 77. Pivotallyl mounted on pins 79 in said block 77 are ro receiving jaw members 80 that are normally'forced togetherbymeans of a leaf spring 81 whose ends are disposed in notches 82 in the end of said j aw members.

A roll 16 leaving the bottom of said feed tube 58 passes between theends of said jaw members 80 and, as the cam 68 moves, said lever-66 and said jaw members 80 are swung to bring the roll into alinement with the roll socket of said slidable member 13. A stop member 83 (Figs. 1 and 4) is provided for reventin a roll from sliding through said 'jaw mem rs. Said stop member may be swung out of position in case it isl desired to empty the feeder tube 58. As the lever 66 is swung the block closes the end of the tube .58 to prevent rolls from dropping therefrom.

j A ram 84 is provided for pushing a roll *'f from the feed jaws 8()y into the socket member 14. Said ram is mounted in a sleeve 85 (Figs.

3,4 and 11) that is slidable in bushings 86, a

lock nut 85a being provided therefor. A

.knob 87 is .provided on the end of the ram l84 for adjusting the position of the ram in the sleeve 85. l

c Secured to the ram sleeve 85 is a vcollar 88 that has projecting pins 89 on which is pivotally mounted the end of a lever 90 whose other end is provided with a roll 91 engaging a cam 92 on said cam shaft 3. Said lever 90 is slotted at 93 and a pin 94 extends through said slot 93 and through a slot 95 in the base, being secured in position by screws 96 and 5 nut 97. Thus the length of the arms-and the i 1 stroke of the ram 84 may be adjusted.

Secured to said collar 88 on the ram sleeve 85 is an elongated arm 98 to whose other end is secured 'a knockout pin 99 that extends 1 through the bore of the slidable seat member -13 to eject a roll 16 therefrom on the return stroke of the ram 84.

The ram 84 has a fixed stroke and the slidv able member 13 lis spring pressed into position to receive the work. Thus when a roll 16 is fed into the slidable member 13, the inal position assumed b v said slidable member will depend upon t ediameter of the roll.

insulatin bushings 103 are provided for saidl screws. e contact member 100 is connect- .ed by an electric wire 104 to the return line 104er of an electric circuit whose feed line 105m is connected by wires 1051 to each of a A number .of solenoid l windings 105. Said solenoids operate discharge or sorting gates 106. Y

Rotatably mounted .in the end of an arm 107 is a vertical rod 108 to whose upper end is secured one end of a cam lever 109 as by a pin i y 110 (Figs. 5 and 6). Said rod 108 extends through holes provided therefor in bosses 111 on spaced plates 112 forming part lof said housing frame. At theother end of said cam lever 109 is a cam pin 113 that engages a cam 114 on said cam shaft 3. A lever 115 (Fig.

. 7) has anv opening 116 in one'end through which said rod 108 passes. A key 117 fitting in keywa s in said rod 108 and lever 115 prevents sai lever from turning on said rod. The end portion of said lever 115 is split and bosses 118 are provided at the sides of the split. A screw 119 connecting said bosses 118 permits them to be drawn together to clam lsaid lever-115cm any desired vertical posltion on said rod 108. This adjustment is necessary to accommodate the vertical movement of said housing 19.

A Acarrier member 120 (Figs. 1, 4 andy 10) slidably mounted in guides 121 has undercut jaw portions 122 fitting over a slide 123 formed on said housing frame 19. Said carrier 120 is actuated by said lever 115 and the end of said lever extends into a recess 124 in the end of said carrier 120. Preferably said actuating lever 115 has a separate engaging member 125 secured at its end, as by a screw 126, said member 1 25 having convexly curved sides. Said recess'124 inlsaid carrier 120 is covered by a block 127. Said block 127 has holes through which extend screws 128 that are screwed into said carrier 120. Springs 129 coiled around said screws 128 press against the block.

Said carrier 120 has a plurality of arcuate electrical contact pieces 130 (Figs. 3, 9 and "12) separated from each other by insulating members 131 and each connected by a suitable wire 132 to one of said solenoid windings 105.I As the contact carrier 120 moves'towards the indicator lever 38, the electrical contact member 100 on said lever will be brought into engagement with one of said contact pieces 130 on said carrier. Knife edge members 133 are provided at each side of each contact piece and the end of the contact member 100 of the lever 38 is beveled; so that the contact members 100 and 130 are guided into accurate and full engagement with each other. c

When the contact member 100 of the lever 38 engages one of said contact pieces 130 on the carrier 120 it closes anv electric circuit .a depending apron 137.

Said gate members 106 are arranged end to end in a series, (Figs. 1, 3, 5 and 6) constituting an inclined chute into which a roll drops when'it is ejected from the gauging seat 14. If the solenoid for any gate is actuated, said gate is raised (Fig. 6), permitting the roll to drop down into a tube 138, from whence it goes to a suitable rece tacle 139. At the lower end of the chute is a tu e 140 that is'permanently open to receive all under-size rolls. When a solenoid is deenergized the gate -106 drops by gravity.

In setting the machine to gauge work of any particular taper and general size, a maximum master roll is placed in the gauging seat 14 and the levers, feed devices and ram are all adjusted so that said' maximum master rolll will4 actuate the gate that is next to the top of the chute. A minimum master roll is then placed in the machine and the parts adjusted so that said minimum roll actuates the bottom gate (that is the gate next to the permanently open outlet). Obviously rolls in between the maximum and minimum size will be automatically separated into groups of different sizes, the number of groups depending upon the number of contact elements and discharge gates.

The above described machine has numerous advantages. It dispenses with the usual requirement of a plurality of gauging stations each required to be set with its own master roll. It is very easy to change the machine to accommodate different kinds o f work. The machine is-very lquick and accurate in operation and economical to oper- Obviously numerous changes may be made' without departing from the invention and I do not wish to be limited to the precise con-l struction shown.
