The invention relates to spindle'reels of the centering type for metal strip material in coil `formY and has reference in particular to an improved spindle reel having coil supporting arms mounted for radial movement by means of a spider and operatively connected to an actuating sleeve by toggle members.

An object of the present invention is to provide an improved reel of the spindle type having toggle members operatively connecting coil supporting arms to an actuating sleeve, and wherein the said coil supporting arms are mounted for radial movement in an expanding or collapsing direction by means of a spider which is completely encircled by the arms.

A more specific object of the invention is to provide a spindle reel having coil supporting arms located radially outward of a spider on lwhich the arms are mounted in a manner to have radial movement with respect to a central supporting shaftand wherein said shaft in turn mounts an actuating sleeve for the arms adapted to move in an axial direction on the shaft.

Another object of the invention resides in the provision of a spindle reel characterized by coil supporting arms mounted for movement on a spider and actuated by a sleeve which effects expanding or contracting movement of the arms. In the present reel the sleeve has a forward part and a rear part located on respective sides of the spider and means are provided connecting the parts so that the sleeve moves as a unit axially of the center shaft* on which it is mounted.

Another object of the invention is to provide a spindle reel characterized by a two-part sleeve adapted tohave axial movement for expanding and contracting the coil supporting arms, and wherein manual means are provided at one end of the reel for positioning the sleeve to thereby adjust the arms.

With these and various other objects in view, the invention may consist of certain novel fea'- tures of construction and operation as will be more fully described and particularly pointed out in the specification, drawings and claims appended thereto.

In the drawings which illustrate an embodin ment of the invention, and wherein like reference characters are used to designate like parts- Figure l is a sectional View, part of the drive mechanism being shown in elevation, of the spindle reel of the invention which embodies the improved form of spider and two-'part actu* ating sleeve;

Figure 5 is an elevational View of the spider.

In the illustrated embodiment of the invention the standard for supporting the main shaft of the reel includes a base l0, Figure l, having side members Il and end members l2 and I3 forming a platform I4. Within the hollow base structure there is mounted a support I5 pivoted at I6 and which supports the electric motor l'l. The vertical position of the motor can be adjusted by means of the threaded bolt it, said adjustment enabling the desired tension to be `maintained at all times on the pulley belts 2E! which operatively connect the pulley 2 l, fixed to shaft 22 of the motor, with the pulley 23 fixed to shaft 24. The said shaft 24 is suitably journalled by the gear housing 28 and a worm gear 26 is iixed to shaft 24 to be thus driven by the electric motor and which comprises the driving mechanism Yfor the spindle reel.

The gear housing 25 includes a transversely extending arcuate portion 23 which receives the worm gear 26 and forms an oil sump for the gear. Above the sump the housing is equipped with the ring 29 for connection with a hoisting Acha-in for lifting the spindle reel. End members are provided at each end of the housing, the member 3l] being located at the right hand end and member 3| at the left end. Roller bearing assemblies 32 and 33 are respectively associated with the end members and said roller bearings journal the main shaft 34 which is thus mounted for rotation in the housing 25 with a substantial portion of the shaft projecting forwardly of the `housing to form the coil supporting portion of the reel. Roller bearing 32 is located on shaft 34 at the reduced end 35 and in a similar manner roller bearing 33 is located on said shaft at the shouldered portion 36. Shaft 34 has a di ameter at 3l to receive the worm wheel 38 which is keyed at 39 and held against shoulder 4t by the threaded ring 4I, The worm wheel 38 has meshing engagement with the worm gear 26 and through the gear and belt drive the main shaft 3'4 is driven by the electric motor Il. `Since the shaft is entirely journalled at one end and the heavy coil of stock material is supported by the reel at the other end of the shaft a cantilever action is set up, requiring the use of substantially frictionless bearings in the journalling means. The device has been found to operate very satisfactorily when the shaft is journalled at 32 and 33 by the roller bearings as described.

I'he shouldered portion 36 of the main shaft 34 is tapered slightly as it leaves end member 3| and at 42 the shaft is reduced in diameter, providing a shoulder which functions as a stop for the actuating sleeve to be presently described. The forwardly extending portion Vof theA main shaft beyond shoulder 42 isagain reduced in diameter to form shoulder 55, Figure 4, and said shaft functions as the coil supporting portion of the reel, the same having the coil supporting arms mounted thereon. Said coil supporting arms, identified by

numerals

43, 44, 45 and 46 are -mounted for movement on aspide'r indicated in -its entirety by numeral 41, see Figures 2 and 5.

The spider hasV four outwardly projecting arm portions or stud portions indicated by numerals 48,

V

49, 58 and 5l, and which respectively mount the coil supporting arms43, 44, 45 and 45. The

.spider is provided with a central opening 52 for receiving shaft 34 and said opening is formed vwith one or more slots 53 by means of which the other. These openings allow passage of connecting rods which connect the two-part actuating sleeve to be presently described.

The spider is telescped over the forwardly extending portion of shaft 34 yuntil it contacts shoulder 55. As a result the spider is mounted on thereduced portion 58 formed for the purpose and by means of keys 51 the spider is keyed in place to prevent rotation on the shaft. The threaded ring 58 functions as a retaining member to hold the spider in place on the main shaft 34.

Each supporting arm is provided with a roller bracket 68 and for explanatory purposes the roller bracket associated with arm 45 will be described since this bracket is shown in cross section in Figure l. The bracket is suitably xed or secured to the underside of its supporting arm by 'means of the transverse pins 6 l and each bracket journals a pair of spaced rollers 62. The spacing of the rollers 62 is such as tol locate a roller on opposite sides of the spider arm portion. For example, the bracket 6l), associated with arm 45, has the rollers 82 located on respective sides of portion 58. In a similar manner the roller bracket for arm 43 has its rollers 62 located on the respective sides of the spider arm portion 48. The structure for

arms

44 and 45 is similar and as a result the coil supporting arms are mounted for movement ina radial direction with respect to the main shaft for the purpose of expanding or collapsing the arms. This radial movement of the coil supporting arms in an outward direction expands the arms for the purpose of gripping the interior opening of a coil of metal stock, whereby the coil is securely held and thus supported by the arms. Then radial movement is in an inward direction the coil is correspondingly released and the same may be removed, or, if the reel is empty a coil of stock may be located thereon.

Each coil supporting arm is operatively connected with an axially movable sleeve by toggle means and in the improved spindle reel of the invention a two-part sleeve is employed, the same having a part on each side of the spider with the parts being connected by connecting bolts passing through passages 54 provided for the purpose in the spider. As best shown in Figures 2 and 4, the actuating sleeve includes a forward portion 63 and a rear portion 64. The two portions are connected by the bolts 65 which extend through the passages 54 formed in the spider 41. The part 83 of the actuating sleeve is formed at its rear with a flange 86 having a number of bolt receiving openings for receiving the threaded ends B1 of the bolts 85. The said bolts 65 are xedly secured to the ange and thus to the forward part B3 of the sleeve by meansI of nuts Y 88. The bolts 88 at their opposite ends are reduced and threaded as at 1Q and these threaded ends are threadedly connected to the rear part 64 of the sleeve. The bolts 65 are flattened at 'H so that they may be gripped and turned by a tool, thus facilitating manipulation of the bolts.

The bolts join the two parts of the actuating sleeve so that they function as a unit and in accordance with the invention each part is p1 vided with a plurality of spaced ears 12 for receiving toggle members such as indicated by numerals 'I3 and 14. Four toggle members 13 are pivotally associated with the ears 12 provided by the forward part 63 of the actuating sleeve. Transverse pins such as 15 function to pivotally connect the toggle members to the ears and as shown in Figure 2 it will be seen that the pins are held to the members by set screws 16. The structure is somewhat similar for pivotally connecting the outer ends of the toggle members to the coil supporting arms. The inside surface of each arm is reinforced as at 'H and the distance between transversely spaced reinforcements is such as to receive the outer ends of the toggle members 13 which are pivotally connected to the arms by the transverse pins 18 which are in turn secured to the toggle members by set screws 19. The toggle members 14 are pivotally secured to the ears 12, provided by the rear part 64 of the actuating sleeve, by the transverse pins 80, and said pins are secured to the members by set screws 8|. The coil supporting arms are alsoreinforced on their inside surfaces as at 82, and the spaced reinforcements of the respective arms are adapted to receive the outer ends of the toggle members 14. The pins 83 pivotally connect the members to the arms and said pins are secured to the arms by the set screws 84.

The actuating sleeve is mounted on shaft 34 for axial movement although rotation of the sleeve is prevented since the connecting bolts E5 pass through openings or passages in spider 41 which is nomotatably xed to the shaft. Actuating movement is imparted to the sleeve by manual means located at the rear of the spindle reel and for this purpose the Wheel 84 is provided, havng a crank handle 85 suitably associated therewith. The wheel 84 is secured to the rear projecting end of the actuating rod 86 which extends through a central bore formed in shaft 34. A :cap member 81, suitably secured to the end of shaft 34 and having associated relation with end member 30, functions to journal the rear end of the actuating rod 86. rIhe forward end of the actuating rod is threaded as at 88 and this end has threaded engagement with a nose portion90, Figure 2, which is in turn secured to the front end 4ofpart 63 of the actuating sleeve. A plurality of as will be readily understood. Rotation in one direction will effect movement of the two-part sleeve in a direction toward the left and presently part 64 will contact the spider All, preventing further movement of the sleeve in a collapsing direction. Figure 1 shows the parts in collapsed relation with part 54 in contact with the spider, with all the toggle members diagonally positioned so as to locate the coil supporting arms in fully collapsed relation. Rotation of the actuating rod 86 in another direction will effect movement of the two-part sleeve toward the right and presently part 63 will be caused to contact the threaded ring 58, preventing further movement of the sleeve in an expanding direction. The expanded position of the parts is shown in Figure 2, with all the toggle members extended whereby to locate the coil supporting arms in maximum expanded position.

The nose portion @il constitutes the part of the actuating sleeve having connection with the actuating rod 86. The other parts of the sleeve are mounted for axial movement on the main shaft 34. By dividing the sleeve the improved structure of the invention is made possible, namely, the location of the spider 41 on the `shaft 34 approximately centrally of the length of the projecting portion of the main shaft. As a re- Sult the coil supporting arms are mounted on the spider at a location midway of the length of the arms and it will be observed that toggle members are on each side of the spider. One set of toggle members is associated with the front part t3 of the sleeve and the other set `of toggle members is associated with the rear part 64 of the sleeve. The present construction of spindle reel is rugged and durable and although the size of the spider is held to a minimum it functions satisfactorily in mounting the coil supporting arms for movement in an expanding or collapsing direction.

The invention is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings as various other forms of the device will of course be apparent to those skilled in thev art without departing fromlthe spirit of the invention or the scope of the claims.
