COILING APPARATUS.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application led February 28. 1917. Serial No. 151,565'.

To all 'whom it may concern.' f

Be it known that I, IVALTER R. CLARK, a

citizen of the United States, residing in Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in (loiling Apparatus, of which the following is a full, clear, and exact description.

This invention rela-tes to metal coiling apparatus, and it refers more particularly to certain improvements in the apparatus disclosed in 'my Patent No. 1,258.092. granted March 5th, 1918.

In this patent there is disclosed a blocker, comprising a coiling device adapted to give the strip a coiling bend or set as it issues from the rollin mill or other machine, in combination 'wit a block located in the line of feed .of the forward end of the bent strip, so that the coiling device will lay the strip on the block. The radius of the curve imparted to the stripI by the coiling rolls or the like is properly chosen with regard to the radius of the block, so that as the strip is fed forward around the block it will hug the same closely, until one layer has been laid on the block, after which the forward extremity of the strip is clamped by the beginning of the second layer or convolution the block being driven at a higher rate of speed than the normal feed of the strip, so as to tension the stri and cause it to wind tightly on the block in a plurality of overlapping convolutions of successively increasing diameter. Another feature of my prior machine is the provision made for forming an open coil by means of the coiler., for whiclr purpose the coiling rolls and block are relatively movable, preferably by havin the block mounted to swing toward an away from the coiling roll. It will thereforebe seen that in my prior device when the block is located over the coiling rolls,

Athe same will coperate with these rolls in blocking, and when moved away from the coiling rolls, the latter may be used independently in forming an open coil, the block being idle during this operation.

` t One of the primary objects of the present 50 invention is to provide a machine or apparatus of the general character above stated, but differing therefrom as hereinafter pointed out, which is very compact. efficient and easily operable. l

I Another object of the invention is to provide a coilin apparatus in which the block and the coiling rolls are mounted on the same frame, and wherein the operation of the apparatus may be very readily controlled.

A further object which I have in view is the provision of an apparatus in which the swingingly mounted blocker has a comparatively small movement toward and away from the coiling rolls, and in which provision is made for rotating the block in a reverse direction, after the winding operation is completed, for the purpose of unwinding the coil to a slight extent, so that it can he readily removed from the block.

Another object of the invention is to provide an apparatus of the character stated, in which the coiler, cooperating with the block, is automatically controlled as the block is moved toward and away from the position in which it receives the strip from the mill, said coiler being automatically moved into a position to grip the strip when the block is moved into strip-receiving position, and being automatically caused to disengage the strip when the block is moved away from the mill to its winding position. By opening the coilingr rolls or their equivalents when the block is moved to one position, said rolls will no longer crimp or set the strip, and the movement of the rolls into and out of the crimping position is effected automatically Without requiring attention on the part of the operator.

A still further object of the invention is to improve' the general construction and operation of ap aratus of the class indicated.

To these an other ends, the invention con' sists `in the novel features and combination of parts to be hereinafter described and claimed.

Fig. 12a is a detail of certain parts shown in Fig. 12; and

Fig. 13 is a view similar to Fig. 12, showing the -clutch .in a position to reverse the direction of drive of the block.

Referring to the drawings, and more particularly to Fig. 2, the rolls of the mill or other machine from which the strip issues are shown diagrammatcally at 20, and associated with these rolls are guides 21 of well known type which direct the strip to the coiling apparatus. rlihis coiling ap aratus comprises a frame or table 22, w1th whlch arel associated a rotary block 23 and a coiling device 24:.

1n order that the ceiling apparatus may be conveniently moved into and outof co.- o eration with the rolling mill as required, t e table 22 is mounted on a guide frame 25, on which it is slidable ina direction parallel to the axes of the mill rolls. In this manner, the apparatus may be pushed or pulled into and out of the path `of the strlp emerging from the rolls, and when the table 22 reaches the desired position longitudinally of the guide frame 25, it may be clamped in position by suitable means, such as, for example, a lock or brake 26 operated by a hand wheel 27 mounted on the lower p art of the table. Referring now more particularly to--Fig. 1, it will be observed that the block 23 and coiling device 2i are located on top of the table or frame 22 and toward 'one end of the same. The coiling device comprises a plurality of coiling rolls mountneogeo@ on the table 22. At the opposite end of the table, a bracket 29 is provided anda driving shaft 30l is journaled at one end in this bracket and at the opposite end in the side frame 28a. driven by'a belt enga ing a pulley 31 on ter is swung away from the mill into the position shown in Fig. 3 to obtain a straight pull rof the strip from the mill, at `which time the coiling rolls 24v are disengaged from the strip so that they no longer crimp or bend the same. necessary movement of the blocker shaft 32, the same is, in this instance, mounted to swing about the axis of the main shaft, and suitable mechanism is provided for` producing the necessary swinging movement to shift the block from receiving to winding position, and vice versa. In the form shown, the block shaft 32 is mounted in d carrier member 33 to rotate therein, and the carrier member is in turn mounted on the 'driving shaft to swin freely thereon. The

carrier 33`is preferab y of hollow form, like a casing, to inc lose certain gears on the main shaft, and it is provided with sleeve portions 33a, 33" fitting over the o shaft 3'()A and constituting bearings on which the car-A This vdr1v1ng shaft 30 may be said shaft, or in any ot er suitable manner.

In order to produce the ico rier may swing relatively tothe shaft. An

extension 34: on the sleeve 33a carries atgits upper end a split bearing 35 for one end of the block shaft 32. At the opposite side of the hollow frame or carrier 33, an extension 36 extending upward from the sleeve 33'J has a split bearing 37 lfor the intermediate portion of the block shaft. It'will be understood, therefore, that by providing this mounting, the carrier and the block shaft carried thereby may be'swung from the position shown in Fig. 2-to that shown in Fig. 3, and Vice versa, vwith the shaft 30 serving as the pivotal point of support.

During most of the operation the block or drum 23 is driven from the main shaft 30 by means of a pinion 38 fixed to said shaft within the carrier casing, and engaging a gear 39 on the b lockshaft. 32. This gear 39 is mounted loosely on the shaft, but it may be locked thereto by means of a sliding clutch member 40 splined-to the shaft 32, hereinafter described. The pinion 38,

izo f .sheet metal shell gear 39, and clutch member 40 are all located 1n the carrier casing. The carrier has at the bottom a wall 41 connecting the bearing sleeves 33, 33", and at the top the .casing is completed by another casing member- 42 which may advantageously consist of a light l suitably connected with the frame work.

The block is swung to and fro in the presenty instance by fluid pressure mechanism act' ing on the swinging fralne or carrier 33. At that side of the carrier which is located t0- ward the block, the same has applied thereto a gear segment 43, as shown more particularly in'Fig. 4, said segment being' concentric with the main shaft. An upwardly extending rack 44 engages this gear segment, and is held in contact therewith by a roller 45 jonrnaled on a pin 46, mounted on a bracket 47, which in turn is mounted on the top 22 of the table The rack 44 is carried at the upper end of a piston rod 48, ofl a piston (not shown) working in a subst-antiallv upright fluid pressure cylinder 49'. This cylinder is adapted to be supplied with motive fluid from any suitable source' (not shown), and the direction of movement ofthe piston is 'controlled by the actuation of vany suitable or preferred form of controlling valve 50, which it is not necessary to describe in detail. A horizontal rock shaft 51 journaled in the lower part of the table serves as a support for the lower end of the cylinder 49, the latter being provided with perforated ears 52 loosely fitting` over said shaft, so that the latter may turn freely while still supporting the cylinder from beneath in an efficient manner. The movement vof the rock shaft 51 is utilized foractuating the valve 50, for which purpose an arm 53 fixed to the shaft is suitably connected with the valveby means of a link 54. The shaft is provided at the end with a treadle 55, by

means of which it may be .conveniently rockedto actuate the valve 50. A spring 56 connected at one end `with the. treadle .55, and at the other end with the frame of the machine normally holds the treadle 55 in the pos1t1on shown in Fig. 4. VIn this-position,

the piston rod 48 occupiesits lowermost lpos1t1on, and the rack 44 and gear segment 434 are in such a position ythat the block is ,located over the coiling device 24 so as to receive the strip therefrom. When, however, the treadle 55 is depressed, in opposition to the spring 56, compressed airwill be. admitted to the cylinder 49 by the valve 50, so as to raise the piston and piston rod, and thereby ther-ack 44 is raised to the position shown in Fig. 5, and it turns thegear segment 43 to such an extent as to swingthe carrier 33 on the main shaft until the block assumes a winding position in which its lower surface is approximately in .horizontal alinement with the bite of the mill rolls. In this way,

. pressed position, so that the block will continue to be held in the winding position shown in Fig. 5 when the foot of the operator. is removed from the treadle. In other words, the construction is such that it is not necessary for the operator to hold the treadle down throughout the operation of winding; it. can be` released as soon as the block has been moved to winding position.. When, however, the winding operation is completed, and it is desired to movetheblock back to the receiving position, shown in'Fig. 4, to receive another strip', the operator places. his

foot on a small treadle piece 60, carried by' the spring latch 57, and" thereby causes the latch to disengage the treadle 55, which thereupon rises under the influence of the spring 56, actuating the valve 50 to exhaust the cylinder 49, and thereby causing the rack 44 to descend and swing thel block back to the coil-receiving position. When the block is again moved to the winding position, the sp1-ing latch 57 -will again snap into locking engagement with the notch 59 in the treadle 55 under the influence ofthe spring 58.

The general arrangement of the coiling rolls'24 is quite similar to that described in my Patent, No. 1,258,092 above mentioned. As shown more particularly in Fig. 8, a three-roll coiler is employed in the present machine, involving an upper coiling roll 61 and-two lower coiling rolls 62, 63 co er-' atin therewith. The strip from the mi l is fed etween the roll 61, on the one hand, and the two rolls 62, 63, on the other hand, and is thus given a bend or set tending to coil it about the block 23 when the latter ispositioned over the coiling rolls. yWhen it is desired to use the device described in this application to form an open coil, the operation of the device is necessarily somewhat different from the operationof the machine disclosed in my patent above mentioned. In the latter machine, when it is desired to Wind an open coil, the block is swung away from over the coiling rolls, in order that the open coil may bel formed above the'coiling rolls independently of the block, but the device described in this application will not operate in this manner since, due to the mechanism hereinafter described by which the coiling rolls 62 and -63 are automatically moved away from the roll 61 when the block 23 is swung away from the position above the coiling rolls, no coiling function is performed by the coiling rolls when the block 4 is swung to the position shown in Fig. 3,

since the coiling rolls-are always separated i a relatively large roll about the shaft 32v but out` of contact with the same, since the diameter of the shaft is much smaller than the inner diameter of the coil formed about the same. formed about the shaft 32 after the block 23 has been removed from the same, the strip, after passing through the coiling rolls` forms an open coil above these rolls, and this coil Iwill rest on supporting rolls 64 and will be held in the proper position by a guard member 65. The upper coiling roll 61 has fixed bearings in the side frames 28, 28a, but the lower rolls 62, 63 are verticall;1 movable to engage or disengage the strip, as hereinafter explained.

The gears for driving the coiling rolls are shown more particularly in Figs. 6 and 8. These rolls are driven from the main shaft 30 which carries a gear 66 adjacent the right hand side of the coiling rolls (Fig. 1). This gear 66 engages a gear 67 on the shaft 61a' of the upper coiling roll 61. The shaft 61a valso carries adjacent the' gear 67 a second gear 68 which drives'the supporting rolls 64 in the proper direction by engaging gears 69 on the shafts of said rolls. The lower rolls 62, 63 are Vdriven from the gear 69, whichdrives through idle gears 70, 71, a gear 72 fixed to a longitudinal shaft 73 located immediately beneath the rolls 62, 63,

thereby rotating said shaft. At the left hand side of the machine (Fig. 1) theshaft 73 carries a gear 74, engaging gears 75, 76

respectively on the shafts of the lower coiling rolls 62, 63 respectively, whereby said colling rolls are rotated in a proper direction.

The coiling lrolls 62, 63 and the shaft 73 are journaled in bearing members 77, one at each side of the coiler frame, and these bearings members or blocks 77 are guided in the frames 28,v 28"L for vertical movement, for which purpose said frames are cut away to form suitable vertical guides 78, as shown more particularly in Figs. 7 and 8. Beneath the bearing blocks 77, a supporting block `79 extends longitudinally of the coiler from one side frame to the other, the end portions. of said supportingl block being located beneath and supportingl the respective rolls 62, 63 may therefore be raised in the When an open coil is to be a position in which t naeaeee guide 78 so as to crimp the stri as shown rolls 62, 63 will be plermitted to descend to ey disengage the strip, as shown in Fig.p7. In order to produce the automatic raising and lowering movement of these lower coiling rolls, I provide suitable mechanism which, in the present instance, is actuated from the main shaft 30 at the proper time. lin the example shown, the carrier orv frame 33 is provided at the left hand side (Fig. l) with a cam 80, adapted to engage a roller 8l. on a crank 82 (Fig. 8) fixed to one end of a shaft 83 journaled in the side frames 28, 28a of the coiler at the lower part thereof, whereby when the carrier 33 is swung tomove the block, the shaft 83 will be rocked. This shaft 83 is provided at di'erent points with toggle connections with the bearing-supporting blocks 79 previously mentioned. Eachtoggle consists of a link 84 connected with the rock shaft 83 and pivoted to another link 85, which in turn is pivoted at 86 to ears 87 dependingfrom the lower surface of the sup- 1- porting block 79, as shown in Fig. 8. When tion indicated in Fig. 7, the toggle'joints are broken, and the coiling rolls are permitted to descend by their weight into an inoperative position, in which they do not engage the strip. The cam 80 is so constructed and arranged relatively to the block carrier that when the block'is in the receiving position shown in Fig. 8, the coiling rolls will be in a position to catch and crimp the strip, but when the `block is moved to the winding position, after the coil has been started, the rolls will be automatically disengaged from the strip. Y

lin order to provide -for a fine adjustment of the lower coiling rolls 62, 63 relatively to the. upper coiling roll 61, l prefer to furnish means for adjusting the bearings 77 with respect to the supporting block 7 9. ln the particular example illustrated, vertical threaded spindles 88, engaging threaded Vsockets in the block 7 9,- adjacent the respective ends of the coiler frame, are adapted to impinge at their upper ends against the lower surfaces vof the respective bearing members 77, and as the spindles 88 are turned in one or the other direction, the bearings of the rolls will be raised or lowered.A rllhe necessary turning movement can be imparted to the spindles 88 by means of worm gears 89 on the lower ends thereof engaging worms on a horizontal shaft 90, having bearings at its ends in the supporting block'79 and provided at one end with an operating hand wheel 91, as shown in Fig. 7. It will therefore be understood that by .turnin the hand wheel 91 in one direction, the splndles 88 can be screwed up in their threaded sockets to engage and raise the bearings 77. so that the rolls 62, v63 can be caused to give the strip exactly the desired bend or set. If when the rolls are in the operative position it is found that they are putting too much of a crimp in the strip, the lower rolls will descend by gravity if the 4hand wheel 91 is turned in the opposite direction to draw down the upper ends of the threaded spindles 88. Intermediate of the ends of the shaft 90 the same has'associated therewith a' gage device, whereby the position of the lower coiling/rolls may be indicated, and by which the proper adjustment of the rolls is considerably facilitated. This gage device comprises a traveling .pointer member 92 having threaded engage- 'ment with a. portion of the shaft 90 and movable over a scale 93. By ascertaining the position of the pointer relatively to the scale, the space between the lower coiling rolls, on the one hand, and the upper coiling roll, on the other hand, can be quickly and readily determined, and if the bite of these rolls is not suitable for the thickness of the strip to be coiled, the necessary adjustment can be quickly made by turning the hand wheel 91 in the proper direction.

The adjustment of the coiling rolls by means of the cam 80 does not interfere in any way with the gage device, as the latter is entirely supported on the movable supporting member 79. The gear drive of the lower coiling rolls is also not interfered with in any way by the vertical movement imparted to said rolls, as the gear 72 is not shifted sufficiently to disengage the gear 71.

When the c oil has been completely wound ou the block, it is usually desired to slid'eit olf the block endwise, and this cannot be done readily unless the block is collapsed in some manner or the coil is slightly unwound. In the present machine, I provide for the unwinding of the coil to a slight extent at the completion of the blocking operation, so that the coil can be readily taken off the block, and this is achieved by momentarily reversing the direction of rotation of the block. This result can be very readily achieved by actuating the reversing mechanism shown in detail in Figs. 12, 12a and 13. When the parts are in the position shown in Fig. 12, the clutch member 40 previously mentioned, which is splined to the. block shaft 32, engages the gear 39 to lock it to the 'block-shaft, so that the pinion I38 (Fig. l) will be effective to rotate the block in\the normal direction for blocking. When, however, it is desired to reverse the block, theclutchl member 40 is actuated to i engage a gear 94 freely rotatable on the block shaft within the casing of the carrier 33. This gear 94 is driven oppositely to the gear 39 because it is actuated from the shaft 30 through an intermediate pinion 95 best 70 shown in Fig. 2, which intermediate inion is driven by a gear 96 on theI main sha In -other words, by interposing the pinion 95 between the gears on drive shaft and block shaft respectively, instead Jof causing the gears to. directly engage (as is the case with the gears 39, 38), the direction of drive of the block shaft is reversed, when the clutch member 40 is actuated to couple the gear 94 to the block shaft. In the particular form shown, the clutch member 40 has teeth 41a to engage a toothed engaging member 41b on gear 39, and said clutch member has a flat friction surface 94 to engage a cooperating friction surface on the gear 94, 85

having a yoke 100, in which the end of the lever is engaged, and the slide rod 99 is actuated from a treadle 101, mounted to swing on the shaft 51, and connected by a rod 102 to the slide rod 99 through an elbow lever 103, pivoted on the frame at 104. A spring 105 acting on the slide rod 99 normally holds the clutch in a position to drive the block in the winding direction, but by de- 100 pressing the treadle 101,',as shown in Fig. 13, the slide rod may be slid to move in opposition to the spring 105, so as to actuate the lever 97 toreverse the clutch. The treadle 101 is only depressed. momentarily so as to 105 unwind the coil only to such an extent as to permit the same to be readily moved off the free end of the block. i

My' machine may be used either as a blocker or as an open coiler, and it is very efficient in performing both of these operations. The machine is very compact in construction, and the controls are simple and few. Only one attendant is required, and as the machine is very rapid in operation, the

output during a given interval of time is very large. The machine can be very easily handled without fatigue on the part of the attendant, and it may be adjusted`to meet a large number of varying conditions, in

spite of itscomparatively simple mechanism. Iy have not attempted to illustrate or describe the various modifications of the construction which may be adopted without departing from the scope of the invention.

I do not limit myself to a machine in which the coiling device is constituted by three coiling rolls, nor do I limit m self to a construction wherein the coiler 1s opened and closed by movement of two lower coiling 33. This forked lever 97 is 90 adapted to be operated by a slide rod 99,

more coils are adapted to be raised and lowered by connections with the block carrier.

Furthermore, I do not limit myself to a machine in which the various controls are effected -by the actuation of treadles, as distinguished from other controlling members. Various changes in these and other details may be made without departing .from the scope of the invention as defined in the claims.

1t will be observed that by mounting the block shaft to swing relatively to the axis of the drive shaft, and rotating said block shaft by a gear thereon meshing with a gear on the drive shat,-the block can be ro tated regardless of its swinging movement to and from coil-receiving position, as the gears are always' in mesh. Furthermore, the construction of the machine is made simple and compact vby mounting the coiling rolls and the block on the same table, and

by driving them from a common drive shaft l located on the same table, preferably by.

tween the same and to. dlsengage the strip gearing as shown. i
