BOLL-GAUGING MACHINE. i

Application led .'l'anuaryf24, 1925. Serial No. 4,539.

My invention relates to .roll gauging inachines and has for its principal object a machine that will gauge taper rolls, such asK sizes therolls'that are satisfactory as to taper.

and roundness. In my copendin application Serial Number 657,644 filed ugust 15,

1923; that partof the machine that gauges the rolls for taper and roundness is shown and fully described, and reference is hereby made to such description.l The present application shows the connections between the two parts of the machine and sets forth in detail the size gauging part of the machine. The invention consists principally in a size gauging machine in which the rolls are carried by a carrier that has an intermittent rotary movement. The'invention further consists in the gauging mechanism and ma: chine and in the parts and combinations and arrangements of parts hereinafter described and claimed.

Secured to' a base 201 as by screws202 is a.column 203 to which is secured a bushing 204'as by keys 205. Ro'tatably mounted on said bushing 204 is a table v206 having a depending bearing portion 207 whose lower end rests -on an antiffriction ring 208. A portion'of the table overhangs the distributing disk 85 of the roundness and taper gauging machine. Mounted-in ockets in the uppersurface of said -anti-frlctionring 208 are pads of felt 209 or the like that may be kept saturated with oil. The bushing 204 preferably has a conical outersurface, so that by'movin it endwise, looseness and wear of the tab e may be taken up.

Around the periphery of therotary table are openings A210 in which are disposed roll The roll carrying plungers 211 are frictionally held in the table openings by means of springs 212 that .are secured to the table and bear against said plungers. To prevent wear on the ejecting a roll from 'v springs 212, bronze wear plates 213 may be interposed between the several springs and the respective plungers 211. The 'springs 212 are preferably secured to the table206 by means of screws 214, said screws also p roviding means for varying the pressure exerted by the springs 2.12 on thel plungers 211.

The lower end of each roll receiving plunger 211 is provided with a tapered recess 215l adapted to receive a roll 216 to be gauged. Preferably a socket piece 217 or -collet of soft steel amd of accurate form and shape is inserted in the socket and the roll isA received in said .socket piece. The size Tof each roll receiving socket 217 is such that the smallestroll -toy be gauged on the ma- `chine will be almost flushA with the bottom of the opening, that is; it will project very the rolling disk rotates at a different speed member. The roll holding plungers are hollow and in the bore of each is a headed pin 218 that bears against a roll 216 and proects above the plunger and .by means of w ich the roll may be ejected.

Referring again to the taper and roundness gauging part of the machine, said machine comprises a main drive shaft"11.verti cally mounted in a framework 12 which is secured on a suitable pedestal 13. A vertically disposed rotatable positioning disklS is pgovided with pockets for receiving. rolls to gauged for taperand roundness. Said positioning disk is fixed' on a hollow shaft 19 on which is a-pinion 20. A. pinion 24 is Vmounted on a stub shaft 25 that extends -a support therefor. The pinions 2O and 24 are held in position as by nuts 26 on the end of the stub shaft and are operatively connectedby suitable gearing. The shaft 25 projects beyond the positioning disk 18 and as a pinion 27 mounted on the inner end thereof, whose hub is screw threaded and has a disk 28 mounted thereon, said disk 28 being of substantially the same diameter as the positioning disk 18 hereinbefore mentioned and being spaced slightly therefrom. Saiddisk 28 is hereinafter called the rolling disk and is providedl with driving means operating through the pinion 27,. whereby from that of the positioning disk.

Rolls are fed to the positioning disk and as said disk rotates the rolls are prevented from droppingtherefrom by a guard plate 44. -The rolls are carried past a taper gauge comprising a horizontally 'disposed floating lever whose outer end 4is provided with electric contact points 46 that are adapted to cooperate with fixed contact points 47 in electric circuits .for operating Sorting devices suchVL circuits and sorting devices not being' shown in detail in the present application).

-V The contact-points 47 are mounted on a yoke member 49. '-The endLvof the Ilever 45 v is forllid and beveled sti tht irlvhen both forks 51 l ar 'against a rol o t e proper ta er the other end of `the lever lies midway lbe- 'tween the fixed contact points 47 The'bot- .tom of the yoke or forkA is provided with a knife edge 52 that bearsagainst a shoe 53 which mounted adjacent tothe path of the rolls. Attached to said shoe 53 and to the lever is a spring 54 that-pulls on 'said lever v'and causesf its V:forks 51to project into the :carries the rollpast the roun path of rolls in the positioning disk.

-After a roll has been gauged' for taper, further rotation.l of thev positioning ydisk 18n @essgauging device.-A eThe curved shoe 53 1s mounted on a block 55 that is mounted at the end of a polygon plunger 56 which is mounted with "its longitudinal axis at right angles to the 'plane of the'positioning disk 18 so as to be Y -end ofthe bore in whichthe plunger fits.

Thusthe plunger 56 is always forced towardv the positioning disk 18 by the pressure of the springs. The back portion of the plunger 56 is hollowed out to receive a friction ends to form resilient arms for yieldably engaging the inner surface of the plunger.

Attached to the central disk'l is a rod 63 which extends through a hole provided therefor in the plate 60 and terminates in a yoke 64. This yoke has a horizontal cross pin 65 which extends through a vertically elongated slot 66 in the upper end of a link 67. Also extending through the upper o1- tion of said slot 66 is a second pin 68 w ich is fixed to a stationary bracket 69 on the frame work. The two pins 65 and 68 are adapted to make contact with both sides of the slot 66, the'pin 68 constituting the pivot about which the link 67 swings when actuated by the pin 65. The lower end of the llink 67 is placed on a yoke 72 on which extends a pin 73 on the end of an arm 74 that is mounted on a rock shaft 75. The lower ortion of the slot 72 is narrow enough toug the pin 73 on both sides thereof, but the upper portion of the slot is considerably wider than the pin, so as to permit the link 67 to swing far enough to make Contact with an electrical terminal 71 when the pin is moved to the wider portion of the slot. As Vthe positioning disk carries a roll past the roundness gauginor device, the difference in the speed of rotatlon of thepositioning disk and rolling disk causes the roll tov rotate on the shoe 53.- The plunger 56 is first 'moved in the housing 57 to accommodate itself to the sizeof the roll, (the lever 67 being held against movement to accommodate this ad-y justment). Then the shaft 75 is rocked to release the lower end of the link 67. ny `variation from true circularity in the roll will cause' the plunger 56 to move, thus operating the link 67 and causing one of the contact points 7 Q on Ithe end of said link'to contact with one of the contact points 71, thus operating an asserting or ejecting mechanism.

Rolls that. have been gauged for taper f and roundness are delivered from the posi- 130 rotatable distribution 'disk 85. Oi. taper able mechanism. Such ejecting mechanism need not be described in connection with the present invention.

A roll that is satisfactory as to roundness and taper is carried by the distributing disk 85past the gate'112 to 'a point beneath a roll receiving plunger 211, where the toe 111 of the roll holding pawl 103 engagesv theA 'cam 106 and permits the roll to rest on the top of a feed plunger 219thatis' mounted on a cam disk 220 with which cooperates a cam roller 221 on a cam 222 that is secured to a shaft 223 on whose end is a gear 224 tance that the roll projects beneath the.'lowery end of the roll receiving socket. The ejector pin 218 is raised by the roll. K

The peripheliy `of the table .,206 is prefer! ably provided with gear teeth 225 that mesh with a gear 226 that is driven in any suitable way yfrom the main drive shaft ofthe machine and is timed with respect to the other parts of the. machine. In the construct-ion shown in the drawings, the gear 226ithatmeshes with' lthe teeth 225 of the table is mountedI on the intermediate shaft 30 that isovdriven from the main `shaft 11 by a star wheel 31 and pin wheel 33. After the roll has been inserted in the roll receiving socket 217, the table is given a slight rotary move-l ment, suiicient to bring vthe roll to a gauging station Secured tothe upper end of eachroll re` ceiving plunger 211 is a contact leverf227 that has one end formed into a contact point 228. f Each contact lever 227 is provided with a spring 229 for yieldably 'holding it in position, and an adjusting screw/230is provided` for adjusting the position of the Contact lever.

Disposed above the column "203 and secured to .the bushing 204 as by screws 231 is an annular supporting plate 232 that is provided with an upstanding rib 2 33 around lts inner periphery. Interposed betweenl the outer peripheral portion of the annular plate and the upper surface df the rotary tablev is an anti-friction ring 234 whose upper surface is'provided with spaced recesses for receiving felt 235 or the like to be saturated -withoiL Secured 'La the annular plate 232 as by thel screws 231 that secure said plate 232 to the Y bushing 204 are vblocks 236 to which are piv- 'otally secured levers237 whose lower ends project through openings 238 in said annular plate 232. Rotatably mounted on pins 239 projecting 'from said table are, rollers 240 tht are adapted,when thetable .ro"

tates, to engage the lower ends of any of said levers 237 that are out ofnormal position. Secured to the upper end of each supporting lever 237 is a lever 241whose outer end1242 is vadapted to ycontact with the ejector pin 218 of a roll holding plunger 211, to eject the roll 216 therefrom." The L inner ends 243 of all of the ejector levers extend to the inner periphery of the annular plate 232 and a ring 244 is'mounted on the upper end of the rib 1233 of said plate to support said ejector levers near their ends and act as a stop therefor. Said levers 241 are provided with shoulders 245 that'engage the side of said stop ring 244, said shoulders being preferably of hardened steel. i

Disposed bove `the inner rib 233 of the annular plate 232. is a `tubular member 246 that is provided with slots 247 into which extend the inner ends 243 of the contact levers 241. The upper portion of said tubular member 246 has a plurality'of springs 248 mounted thereon, as by pins 249, there being one spring for each ejector lever 241,

and each spring 248 being connected to anejector lever 241- as by a,link.250 pivotally secured to both'. The engagement of the shoulders 245 of the ejector levers 241 with` the stop ring 244 prevents the ejector levers 241 from being forced downwardly by the springs 248 and links 250. A11 armature 251 is secured to each ejector lever 241as by a slot 252 in the armature in.which a pin`253 on the ejector lever. j Threaded into the bore of the tubular is provided with a depending `annular* rib 256v thatengages the springs 248 and causesl them to press downwardly on the-links 250" thatconnect said springs with the ejector.

levers 241.

Theannular plate 232 is upstanding wall portions 257A tween which are mounted the cores 258' of electromagnets. The` electromagnet coils 259 are mounted o n said cores and are secured in @vided with position by means of a ring260 disposed on top of them andsecured to the several., wall members 257 as by screws 261. The ring v is provided with a fiber outer wall 'orfco'ver- 262.` Mountedon the outer portion 'of each wall member'257' of the annular plate 232 is a'bracket 263. that is secured to the wall member 257 as, by a screw .The'bra'ck-g ets 263 arev insulated fromeachother by, means of -fber washers 265 andeach braclq -laof that is followed by the Contact portions 228 of the several contact levers..y The ring 260 I et is insulated from its securing. screw 264 byia fiber sleeve' 266. Each bracket 263 has a projecting lug 267 in which is'mounted a Contact screw 268, the several contact screws being disposed in the circular path and the fiber cover 262 form an annular chamber in which is a wire 269 that is connectedwith an end of the Wire of each of the electromagnet coils 259. The other end .of said wire 269 is connected with one terminal of 'a source of electricity indicated at 270. The other end of the wire of' each coil 259 is connected withY the bracket 263' that carries -its contact screw 268. The other terminal ofthe source of.electricity 270 is grounded to the frame lof the machine, and the contact levers 227 of the roll receiving plungers 211 areffalso grounded to the frame.

Secured to the flange 255 of the sleeve 254 as by screws 271 is a bracket member 272 that is provided with bearings 27 Sain which is rotatably Ksupported a horizontally disposed shaft 274. Said' shaft 274 is provided with a bevel gear 275at the end that meshes with a' bevel gear 276 on a shaft, as the main shaft 11, whereby said shaft is continuously rotated. The end of the shaft u 274 is disposed above the center of the, size gauging portion of the machine. Secured to the end of the shaft'274 is a cam 277 to which is `pi'votally secureda cam roller 278 as b a stud D279. Said'cam roller 278 rides' in t'e slot 286 of a cam 281 -from wohich depends a plunger rod 282. The cam 277 is slidably vmounted inv the bracket member 272 and is held in position b means of a cap' 283 that is secured to the racketI meniber 272 as by screws 284. Secured to the lower end o the plunger rod 282 .is a man- `drel 285 that moves up and down in the-bore of the tubular member 246 and of the rib 2330i the annular plate 232.l

At -each gauging' station a suitable vcon- .veyer 286 is provided to receive a roll ejected `from a roll holdin plunger at that station. Said conveyer eposits the rolls in a suitable receptacle 287.

Referring againn to the roll holding plungers 211, it will be remembered that the contact lever 227 of a plunger will project upwardly a -distancedepending upon the diameter of a roll 216 therein. The several contact screws 268 are arranged in stepped relation, running fromthe argest to the smallest.' If the roll in aroll receiving shoulder 245 is'clear of the stop Lasarte ner end 243 of the ejector lever so that the ring 244 on the Yrib 233 of the annularA plate 232.

-rangement raises the inner end 243 of the ejector lever 241 and lowers the outer end 242, thus causing said outer end to strike the top of the ejector pin 218 and eject the roll 216. This movement of the ejector lever. 241 is accommodated by the slot and pin connection between the e'ector lever 241 and the armature 251. A ter the roll has been ejected, the next rotation .ofthe table will bring a roller 240 into contact with each lever 237 that has been moved, thus swinging said lever 237 and its ejector lever 241 to normal position and ca'using the ejector lever to be reset. It will be seen rom'the foregoing that there are three positions of each ejector lever 241 and its associated parts: namely, first, the normal .position shown in Fig. 1 in which the inner end 243 of the ejector lever 241 rests against the stop ring 244, and the armature 251 of the ejector lever is/spaced away from the core 258 of the electromagnetr; second, the position shown in full lines in Fig. 7, in which 4the armature 251 of the ejector lever 241 has been attracted' by the energized core 258 of thevelectromagnet, the outer end 242 of the ejector lever swung downwardly slightly and the inner end 243 moved upwardly and inwardly so that it projects into the bore of the tubular member 246 in position to be engaged by the shoulder 288 of the mandrel 285, and the supporting lever v237 is moved into more or less vertical position;l and, third,- the osition shown in dotted lines in Fig. 7 in w ich the inner end 243 of the ejector lever 241 has vbeen swung upwardly by the shoulder 288 on theemandrel 285 and the 'outer end 242. has been swung down engaging the head of a knockout pin 218 and ejecting a roll 216 and forcing the roll holding plunger4 2,11 down int() normal position.

The operation vof the machine is as follows:

rst gauging station. Said-Erst gauging Htl A: roll 216 that is satisfactory as to roundvrotated soV as to bring the rol 216 tothe stationis set to eject all rolls that are larger thanapredetejrmined size. VThe step by step rotation of the table lAcontinues until through the electromagnetand causing the the roll reaches the gauging station that is set for its size. At this station, the con` tact point 228 of the' contact lever 227 of the roll holding plunger 211 makes contact with the contact screw 268 of the gauging device, thus closing the electric circuit armature, 251 of-the ejector lever 241 to be attracted, the outer end of the ejector lever roll into the conveyer 286, which delivers it to a receptacle 287. The knockout movement also causes the roll receiving plunger 211 to be lowered to its lowerinost position, in which it is ready to receive another roll at the feed station. i l

`Atthelast station, there is no gauging device and the ejector lever 241 atsaid station is not provided with a contact shoulder, but the inner end thereof always'extends into the bore of the tubular member 246. Thus, said ejector lever at the last station is operated on each upward movement ofthe mandrel; and any roll that is too small to be eject'ed at any of the preceding gauging stations will be ejected at the last station. 'f

The rolls that are too large andthe rolls that 'are too small may be gauged` on other` 'y machines that are set to accommodate them.

After a roll has 4been ejected, the neict rotation of the 4table causes a roller 24() on vsaid table to `engage the lever 237 to which is seclired the ejector lever' '241 that has just been operated. Said lever 237 and ejector lever 241 are thus restored to normal position and the shoulder 245v on the inner end of the ejector lever engages the stop ring'. `244. v

The size gauging' machine shown in the has sixteen gaugin stations of i e first/is set to eject al rolls above a predetermined size, thenext fourteen are set to ejectrolls of progressively `smaller* sizes and the'last is provided with a knockout* device that always'ejects a roll thaty reachesv sai -last --station.'1 "Obviously the Lmachi'nejm y be'fmade'fwith any-'desired number of stations.
