Claims.

This invention relates to surface grinder machinery in which abrasive tape or an equivalent cutting agency may be eiiectively utilized, and more particularly pertains to improved interchangeable reel drive equipment of the reversible type by which a long batch of round or flat reelable stock may be dragged longitudinally at high velocity in successively reversed passes into operative engagement with a plurality of slowly fed abrasive elements carried by either stationary or rotating head means.

The present high duty apparatus may be installed at moderate first cost and is especially adapted to rapidly and economically rough grind a reloadable batch of larger gauged hard alloy steel or the like high tensile stock on a low labor servicing basis, preferably without requiring any fast moving working parts except for the treated stock itself.

The instant grinder improvements are primarily directed to the use of a pair of conjointly driven reels of relatively large diametral size of which one such may be demountably coupled to a sectionalized drive axle whereby to expedite batch replacement and maintain a high productive machine output as measured over a protracted operating period. Each such reel is further equipped with controlled dual drive clutch means, preferably of the electromagnetic type, which are alternately rendered inactive to successively reverse the travel direction of a treated batch. Also associated with said reels are long-range motorized cross-shaft means and other structural refinements serving to promote the end in view.

The object of my invention is to devise an cicient and compact work piece drag system of the indicated reversible reel type capable of effectively processing a long batch of stock when successively passed longitudinally through grinder head means to complete its abrasive treatment at a relatively fast productive rate and which system requires a comparatively short shut down period between batch runs in which to operatively install a next succeeding batch of stock for similar treatment.

Reference is had to the accompanying three sheets of drawings which are illustrative of a preferred exempliiication, and in which drawings:

Fig. l represents in approximate scale, a plan layout oi my controlled reel assembly, and Fig. 2 is an elevational side view thereof.

Fig. 3 shows a gear driven fore-end region of a reel axle taken along 3-3 of Fig. 1, and Fig. 4

a detail of such gear transmission taken along the broken line 4--4 of Fig. 3.

Figure 5 details a split aft axle end region together with an interposed nut coupling for my demountable reel.

Fig. 5A is a sectional detail taken along SA-EA of Fig. 5 to show abutting axle parting faces that may be relatively shifted in a definite transverse direction without material face separation.

Fig. 6 is cross-sectionally taken along B--G of Fig. 5 to reveal a preferred ratchet mechanism for a rapid loosening or securement of the coupling nut, and Fig. 'l depicts a top view thereof.

As arranged in Fig. 1 for the treatment of wire stock, my system may comprise a pair of anged reels In and II that are respectively mounted upon the mated driven parallel axles I2 and I3. These axles may each be suspended between a fore main bearing pedestal I4 and an aft bearing I5. The respective overhanging fore bearing axle ends may each be separately driven by a compactly encased transmission unit I1 (see Figs. 3 and 4). Each such unit may be provided with a bevel gear or the like skew means I8 of which its sleevelike hub may be coaxially and rotatably disposed about its axle as shown. The aft end of such gear hub may have a sleeve pinion I9 affixed thereto. Mes-hing with this single pinion are multi-ple gears such as 20 respectively carried upon a separate compound spindle 2l. Each spindle may bridge the opposed end walls 22 and 23 of the split stationary casing utilized in unit I'l and which walls are alignedly apertured to allow of freely projecting the fore axle end therethrough. Conjointly mounted upon each such spindle is a pinion 24' that interlockingly rotates in unison with its mated gear 20. These multiple pinions mesh with a common keyed axle drive gear 25 and collectively provide for an ample combined reduction ratio between the high speed unidirectional main motor 26 and either of the slowly rotated reel axles I2 and I3. Each such speed reducer is purposely designed to unstallingly operate in reverse.

In accordance with the Fig. 1 assembly, the respective bevel gears I8 of these axles may be selectively coupled to the main drive motor 26 through the cross-shaft `2'I mounted between the auxiliary bearings 28 and 29. The overall length of such cross-shaft is herein kept shorter than the interspacing between the axles I2 and I3 and lies in parallelism with the suspended work piece length that tangentially interconnects my reels Ill and II. A shaft drive pulley 3i! located between said bearings may be belted to the unidirectional main motor 26 to rotate said shaft at a considerably faster speed than the axles I2 or I3.

Separate electromagnetic clutches SI and 32 may respectively be interposed between each such auxiliary bearing and its contiguous loose bevel gear in the Fig. 4 manner to independently command the driving of its associated axle. Each such clutch may comprise a faced annular slip disc or releasable grip elements 33 that encircle the cross-shaft 21, also a switch controlled eld coil 34 that may be energized from any suitable current source through the commutator rings 35 and lead wires such as 35. As indicated by a'rrows, the Fig. 1 installation is such that the reel axles may be selectively motor driven in opposed directions whenever one or the other 'of said clutches is made operative. The eld coil "current flow may be so controlled that only one magnetic clutch is'allowed to become active at any given time and purposely leave the other clutch idle. Both reels will then run in` a like direction because of being interconnected by the work piece and the released slip disc 33 of such uncoupled clutch will then be freely rotated by its associated reducing gear I1. Y

As detailed in Fig. 5, a transversely split axle I2 may comprise a fore or master section of which the aft end region is encircled by an outstanding endless flange 31, the flange hub being aixed in place to provide for an annular thrust face 39 and separable axle parting faces 39 that whenY uncoupled, are rendered relatively shiftable in a transverse direction, that is to say lengthwise of the radially disposed key 44 without requiring a substantial separation of the faces 39 (see Fig. 5A). A substitutional tandem aft axle section may be Vequipped with a perimetricallythreaded flange 4I that overhangingly abuts said ilat parting face 39 to constitute an aligned sectionalizedfaxle. Said flange threads cooperate withY 'a demounta-ble lscrew coupling agency 43 that renders interchangeable my reel lil, Said aft Yaxle section may lfurther include la tubular shank component 43 that is preferably tightly telescoped as a plug and keyed atv 45 Awithin a standardized bore of the reelhub 6 to project rearwardly beyond the y-partingface 39 and connes of the `axlesupport lbearing I5. An axle web vcomponent 42 may s-pan the `flange 4I as shown. It willbe obvious thatas'a demountable reel upholding agency, such substitutional -aft axle-section may also be incorporated integrally with the reel hub. Y

The interiorlyshoulderednut 43 when screwed up into operative position, brings-thenut Yshoulder into tight clamping engagement with the thrust face 38. A straight-edged, radially disposed supplementary key 44 *having la vlenga-th shorter than the thread bore of the nut 4'3, may be interlockingly interposed `between `the abutting parting faces 39 to prevent relative rotation therebetween while said key remain slidably entered within the web 42 bythe semidepthrange designa-tedlI-I. Such unitarycoupling means may be speedily connected by screwing up a single axially centralized nut or the likefa-ceclamping agency. The released nut 43 maybe retracted to theex-tent mar-kedG, whereupon-the demountable reel I'9 may be unobstructedly lifteddirectly upward when lthe `key 44 stands vertically without requiring 'a material separation between the ma-ted substantially -vplaniform parting --faces 39. A spaced stop-collar 4'6maybe applied tov-the forward hub end of the axle flange 31 and the lil 4 contiguous face of the nut 43 may be provided with a stop pin 41. As dened by dotted and dashed outline in Fig. 5, a split collar 48 may be entered between said stop pin and the collar 41 to block the assembled nut from inadvertently backing off in either direction of reel rotation.

In Fig. 2 there is schematically indicated a retractably mounted arcuate saddle 49 disposed beneath the perimeter of the demountable reel I0 and serving as a cradle that facilitates the hub centering of a substitute spare reel when likewise coupled in the Fig. 5 manner. One end of such saddle may be pivotally mounted at 50 and the other end actuated by ram means 52 whereby to bodily raise or lower such interchangeable reel into place. In addition, the hook of a traveling chain hoist 53 may be employed to remoVe a completed batch together with its detachable reel, or to transfer into place a substitute reel initially having an unground strand batch prereeled therearound.

The smoothly turned rim component 55 of each reel is preferably kept to a common large diametral size to obviate undue bending stress when laying a relatively heavy gauged work piece 54 thereon. 'Said rim may be integrally interconnected to its hub 53 by plural reel arms 51. All my demountable reels may be permanently tted upon a standardized hub plug component 49. The several batch layers may herein be held to a continuous length of about one ton or more in weight and thereby alford an adequate time period between next successive reel reversals.

Because of the relatively large reel diameters required for treated work pieces of larger gauge, it is preferred to locate their horizontally parallel axles I2 and I3 in a servicing pit below the level of a beam supported oor 5I and have both companion reels I!) and II extend upwardly through said oor in the Fig. 2 manner and tangentially suspend the work piece horizontally between the top regions oi both reels as shown. It will be observed that the non-demountable solid reel axle I3 may be kept devoid of any coupling means, its aft 'end in this instance may merely project beyond its bearing I 5 and be enlarged to a standardized hub bore size by a cylindrical bushing 59 (see Fig. l). As regards the coupled reel I8, it is the intent to provide for interchangeable spare units and to utilize such substitute reels for prereeling an unground batch of wire thereon by extraneous means for subsequent coupled installation onto the master section of the axle I2. When completely processed, the nished batch may be restored upon its original reel I0 prior to its batch removal.

Each initial layer of such prereeled batch may include a repeatedly used lead end section welded to a terminal of the treated batch proper and having a free lead end affixed to its reel perimeter. Such renement insures that the entire interposed batch may be uniformly ground at high velocity irrespective of slowing down during reversing periods. When operatively coupled in place, the outer prereclcd batch terminal of the reel I 0 is intended to be spliced to the free lead end section of the companion reel I I so that when one of the magnetic clutches such as 32 is thrown into commission, the other idling clutch 3| will allow its axle IS to be dragged in a corresponding direction by 'a suspended portionof the reel interconnecting strand 5'4.

Referring in detail to-Figs. 6 and '1, these disclose 'a preferred rapid mode for securely tightening up the unitary coupling nut 43 by the use agie-4,465

of* auxiliary motorizedmeans rather than by manually opera-tedV wrench means. A- pai'r ot upstandingrocker arms Si` and B2= mayA be pivoted about each sidei ofv the reel axle ll2- with their swinging ends interconnected bythe tie rod 63. This rod and its associated parts-are laterally offset out of registry with the key 44 to-clear the hub of the reellil when raisedl vertically. A medial portion of said rod is shown provided with a pivoted nut pawl 64 adapted to releasably engage an endless series of ratchet teeth 65?' that circumscribe thenut axis. Said pawl may be resiliently reta-ined: by balanced springs such as 56 and the pawl selectively urged' into operative engagement with said teeth as indicated in full outline: This shiftable pa-wlmay also be snapped through the angle T into a dotted neutral posi*- tion andmanual-ly thrown onward into its reversedv position. For normal reel running conditions; said pawlisplacedin such cleared position. A gearedv motor 6l'I m-ay have its slow speed outletshaft equipped with a crank 69 which by the adjustable feed rod Et' serves to propel the bell crank ratchet 61 in toggle fashion whereby to forcibly actuate the coupling nut 43 in either direction. As an equivalent; a reversible motor may be directly geared to impart a slow continuousmovement rather thanintermittent ratchet movementsV to said nut.

Furthermore in lieu of the cited Fig. 5 split collar 48, Fig. 6v resorts to an automatic safety or emergencyi tell-tale device comprising an abutment lug 'ID- whichy may be floatingly interposed between the stop collar 4G and the opposed pin 41- to normally clear the latter whilethe reel I0 iskept in rotation. Said lug may be shiftably carried by the stationary pivot 'i'l and provided with a depending twin profile cam l2 that is spring urged into a centralized position with respect tothe roller switch arm '53; A double push button snap switch 14 may thereby be automatically thrown into its cut off position should the nut 43 accidentally start to back off in either direction of reel rotation and allow the stop pin Il` to collide with the lug 10. The switch lead wires such as 15 may be series connected to command current flow through one of the electromagnetic clutches to bring the reeli'ng system to rest slinulkil 'the Vreel nutbe'clome yloosened While in service;- L

Such single housing may be provided with mul-A tiple tapes of suiiicient collective width to combinedly grip the perimeter of a treated work piece having a circular profile up to its safe drag load capacity. Each such tape may be independently impressed into engagement with said Work piece by suitable backing jaw means, preferably of a releasable type.

The functionalbehavior of my reel drive system is thought obvious from the foregoing description of its elements. As Will be understood, the respective lead wires 36 commandingthe magnetic clutches 3 l` and 32 may be separately placed under the positive control of manual or automatic switch means. Assuming tha-tademountable spare reel it with a prereeled unground batch to have been operatively installed in place' upon its master axle section and the couplingnut ll3to have been adequately tightened by the Fig. 6 instrumentalities, then by initially energizing the motor driven clutch 32', the Fig, 1` assembly is ready to transfer such prereeled batch through the grinder housing 9i and on to the previously emptied reel il at a iinally attained uniform pass velocity. Such velocityv is preferably held at a predetermined travel rate of several thousand feet per minute between reversal periods.

When the trailing end' region ofz said transferred batch is reached', the clutch 3-2 is disengaged, which slows up said strand interconnected reels. The considerable abrasive drag imposed upon the treated strand effects a fairly rapid' deceleration of the rotating reels. Upon approach to rest, the other clutch 315 may be manually or automatically energized in sequencev by switch means to-reliabls7 reverse the loaded reels lil-and ll' irrespective of their axle spacing.

If preferred, all of the tape backing jaws may be released during each starting periodl to' promote rapid reel acceleration. The initial lead wire affixed to either batch end is intended to be sufliciently long to afford an appropriate number of rim turns for present needs and thereby assure that the entire active batch may be evenly processed throughout its length. The use of batch lots approximating one ton in weight, materially extends the time period between reel reversals and correspondingly reduces the frequency of clutch switching. Such infrequent reversal practice obviates overheating of thev main drive motor and provides adequate time in which to air cool the coiled work piece between successive passes.

The required-number of repeat passes depends among otherl considerations, upon the hardness of the treated material, the collective Width of the abrasive tapes, the rate of tape feedv and the extent to which an initial work piece size needs to be reduced. Upon having reached a prescribed requirement with the completed batch rewound upon its original reel It, the main motor 26 may be shut down, whereupon my centralized hub nut 43 may be unscrewed by the auxiliary motor El and the batch removed for subsequent bundling or the like. An interchangeable spare reel may then be substituted and the same abrasive pro'- cedure continued on such renewed batch. As a consequence of my unitary single axle coupling and to the end that a low cost per pound ofprocessed product may be obtained, such spare reels may be installed with dispatch kand the net' grinding rate kept to a high level of effective produc'- tive output at the minimum servicing labor and without having to unduly interrupt active performance while reloading the reels of my grinder machine.

While my unidirectional motor 26 remains in operation, it is rendered responsive to a clutch shift without having to wait during each reel reversal for such drive to attain its full rated speed. Furthermore by locating my heavy duty clutches 3| and 32 upon the low torque cross-shaft 21, the clutch size and cost may be materially lowered in comparison to equivalent clutches installed directly into the high torque axles l2 and i3.

The foregoing disclosures will, it is believed, make evident to those skilled in this art, the outstanding commercial advantages afforded by my refined heavy duty reeling system. It will be evident that certain structural aspects of the disclosed reeling and housing improvements may readily be modied to produce a like result, all without departing from the spirit and scope of my invention, heretofore described and more particularly characterized in the appended claims.
