- diameters. The invention relates particularly to that type of gauging machine in which the diameter of taper rolls is meas-v ured by' the distance that the rolls project axially from a tapered socket.

The invention has for its principal object a machine that is automatic in'its operation,

that is simple in construction and that as-- sorts the rolls economically and accurately. The invention cqnsists principally 1n mounting the gauging devices so that the are vertically movable, in rotating the work intermittently so that the rolls are successively brought into alinement with the various gauging devices and then moving, said gauging devices toward the work. The invention further consists in loosely mounting -the rolls in a rotary indexing member and in transferring the rolls from said indexing member into tapered receiving sockets at the gauging stations. The invention further consists in the means for returning the rollsfrom such taper receiving sockets to the roll carrier, to be delivered to the next gauging station or ,to be ejected from the machine. The invention further consists in the ganging and assorting machine and in the parts and combinations of parts hereinafter described and claimed.

Flgs. 8, 9- and 10 are vertical sectional I views showing different positions of the gauging devices.

The machine is provided with a suitable housing. 1 at the center of whichis rotatably mounted a ring or disk 2 for receiving indexingrolls 3 to be measured, said index-h top'of the housingl. Said indexing ring, 2 is provided with a multiplicity of holes or pockets 4 (eighteen being shown in the mg ring being horizontally disposed at the drawings) that receive the rolls 3 and carry,

them through the machine. The indexing ring 2 may be made separate from its hub;

portion or member 5 and secured thereto as by screws 6. Said hubportion' is journaled in a suitable bearing portion of the housing and packing orbearing material may be in- Secured to': the depending hub portion 5 of the indexing'ring 2, as by a key 7, is a gear 8 that is driven by a pinion 9 that is operated by means of a Geneva movement. Said movement comprises a mounted disk 10 having projecting radially disposed ortions 11in which are radial slots 12 a' ap ted to be engaged by a in 13 on a pinwheel 14, the movement of t e pin 13 in one of saidslots 12 causing the wheel. 10 to rotate. Said pinion 9 is-mounted to of the star wheel 10 between Said radially.

rotatably ortions 15- i and are adapted to be engaged by an arcuate rib 16 onsaid pinwheel 14; so that when the slotted wheel 10'is not being moved by the pinwheel 14 it is held against movement by reason of engagement ofsaidrib 16 with a concavely curved portion .15 of said star wheel 10.

Said pinwheel 14 is secured to a stub shaft 17 that isflsuitably journaled in the housing 1 and is driven. by means of miter gears. 18,

one secured to said stub shaft 17' and the other to a drive shaft 19 suitably mounted in the housing. Said drive shaft 19 is suitably connected with some source of power, as by means of a worm wheel 20 and a worm 21 mounted on a worm shaft 22.

Preferably said stub shaft 17 is provided with a gear 23 that meshes. with a gear 24 on a shaft 25 that extends vertically through the top of the housing 1. Said shaft may be caused .to operate a suitable feed drive mechanism. A plate 26 may be provided with bearing portions 27 engaging said feed drive shaft and the upper end of said stub shaft 17.

The worm 'shaft 22 may be driven by means of a pulley 28 and said pulley is met I erably provided with a friction clutch 29 device to prevent injury to the gauging mechanism. v

Said drive shaft 19 is preferably provided'withia cam 30 secured thereto, said cam working against oppositely disposed rollers 31 in a yoke member 32' depending from a spider 33 that is provided with a central guide stem 34 extendingflhrough a v a central bore provided therefor in said hub spider 33 is secured a ring 36 as by pins "37. Said rin portion 5 of said indexing ring ing device indicated generally by 39. Ad-

justably securedto each stem- 38 is a'hollow block 40 provided with a cross bore 41 ex tending therethrough, by which. it is mounted onsaid stem 38. A lever arm 42 extends through each of said blocks 40 and is pivotally mounted in the block as by a pin 43. Each block 40 is provided withfa set screw 44 that engages said lever-arm '47 disposed in' said recess, whereby the ball 42 and on the other side of the lever arm is provided with a recess "45in which is mounted a ball '46 that is seated on a spring 46 is pressed against said lever 42 andsaid lever is held between said ball and said screw.

Each block 40 is provided with a cap 48 in which is fixed a pin, 49 that has a shoul dered portion .50 fitting in said block 46 and has a threaded extension 51 fitting in a screw threaded hole 52 in the top of said stem. 38 whereby, by rotating its ,said cap 48, each block 40 may be raised orlowered ;on its stem'38- without rotatingsaid block on said stem. A wedge nut 53 or the like is provided for securing the block in position on said stem. Each block 40 is provided with a pin 54 that projects into a slot .55 in the stem thereby holding the block 40 and lever arm 42 in proper angular position relative to the stem 38. At one end each lever arm 42 is'provided 7 with' a spring member 56 that is bent over one end of the arm and extends lengthwise of the arm along the underside thereof and is secured thereto as by pins 67. Each spring, 56 is provided with a contact point {38 adapted to engage a contactpoint 59 that is mounted at the end of *a screw 60 extending through a plate 61 that is secured 2. v The downward movement of the spider is limited by adjustable stop screws 35 mounted in the which block 62 is secured, as by a bolt 64, to the body of the machine.

to an insulated block 62 as by screw s63, 1

At the end opposite said spring arm (that is'at the end of the short arm of the. l ever)- ieach lever 42 extends into a slot 65 provided therefor in the upper end of a plunger or contact arm 66, the underside of the lever resting in the bottom of said slot 65 and said lever being provided with a spring 67 that rests against a pin 68 in the top of said slot; Each 0f said contact plungers extends provided therefor on the housing. 7 Mounted in the housing beneath each conthrough a suitable guide or bushing 69 tact plunger 66 is a hollow socket member,

'70., the upper end of whose bore is formed into a socket 71 whose taper is'the same as, that of the rolls3 being gauged. Extending through .the bore of each socket member 70 is a knockout pin "72 Whose lower end rests on a setscrew 73 mounted 1n said' carr er ring 36 that supports thegauging stems.

When the carrier ring is in its uppermost position, .as shown in Figs. 1 and 8, th upper ends of the knockout pins 72 are flus' with the tops of the socket member-s70 The operation of the machine is as follows: 7

By any suitable feeding device, 'the rolls 3 are fed, one at a time and small end down into the pockets'4 of the indexing ring.

Rotary movement of the. indexing ring brings said ring into position so that the roll receiving pockets 4 thereof are in ahnement; with the contact plungers 66 of the 1 au un devices 39 each roll restin on a knockout .pin 72. Rotary movement of the indexing ring 2 is prevented by the Geneva movement and the cam 30 lowers the spider 33 and carrier ring 36 and the parts carr ed thereby. As said parts are lowered, the

knockout pins 72 drop down in their socket members 70, permitting the' rolls to drop into said tapered 'sockets '71 in the socket members.

The gauging gauging devices are arranged so that they will fit successively smaller rolls: thatis the A takes place at'the lower end of the stroke of the gauging devices' Said.

largest roll'willbe ejected at the first gauging station, the next smaller roll at the next station' and so on. Fig. 9 illustrates the position of a gauging device in whose socket member 70 is aroll just smaller than the size for which said device isset. It is noted that the contact plunger 66 engages the top of the roll 3 but does not bear against 11;

sufficiently to cause the plunger to be forced upwardly. 1 In Fig. 10, however, the con-' tact plunger 66 is forced upwardly thus tilting up the short arm of the operating lever 42 and swinging down the ,long arm against the pressure of the spring pressed ball 46 and the spring on the short arm of the leveri The contactpoint 58- on the contact spring 56 f is pressed against the adjacent contact point 59, closing an electric circuit (not shown in the drawings), and energizing an electromagnet 74 secured to the housing" adjacent to the gauging device 39. Y

The energizing of said electromagnet 74- attracts the armature 75 thereof and pulls said armature away from its normal position in which the other end 76 is immediatelybelow the path of travel of-the roll end with a finger or pawl 79 pivotally setheir respective electromagnets 74 are enercur'ed thereto and adapted to engage a shoulder 80 on the upper surface of thealmature 75 when said armature is in its retracted or open position and when the carrier ring 36 is. at the upward limit of itsmovement. Thus the downward movement of the carvrier ring 36 andthe gauging devices 39 prior to the gauging operation will 'cause any open or retracted armatures 75' to be reset, due to the angular position of the pawls 79 relative to the setting pi'ns 7 8 and their pivotal connection therewith; The arfnatures 75 are reset before the end of the downward movement of the carrier ring 36 and the further downward movement causesthe outer portion of eachpawl 79 to be tilted up, due to the'pawl swinging about the shoulder 81 formed at the edge of the surface 82 that normally rests on top of the armature. Thus the outer ends of the pawls 7 9 will be withdrawn from engagement with the shoulders 80, leaving the armatures 75 free to be retracted into open position if gized. After the gauging operation has been completed at the lower end of the movement of the carrier ring 36, said carrier ring moves upward carrying with it the gauging devices 39. Said v carrier ring 4 likewise moves the knockout pins 72 of the socket members upwardly and said'knockout pins push' the rolls out of thetapei sockets" 71 into the pockets 4 of the indexin ring,

tops 0 said socket members. When the upward movement of the carrier ring 36 and its mechanism has rminated,

- the indexing ring 2 is rotated one stcp'by its operating mechanism. During this rotatlon any rolls that have actuated the ganging mechanism 39 of the previous station drop out through the open passageways formed by the retraction of the respective armatures 75. The other rolls in the indexing ring 2- ride over the end or gate portions 76 of the other armature-s and are carried to the next gauging position where" they rest on the ends of knockout pins 72 as above described. spider 33,. the carrier ring 36 and the gauging devices 39 and the armature setting devices 78 then begins, during this downward. movement'the-open or retracted armatures are reset and at the end of the downward movement the gauging operation is repeated.

The above described gauging machine is Simple in construction and operation and,isvery economical ,and accurate. I advantage of gauging the diameter of rolls according to the amount of projection or drop from an accurately tapered socket.

Obviously numerous changes might be made It has the he downwardmovement of the without departing from the invention and I do not wish to be limited to the precise construction shown.
