In the drawings, l indicates a base or bed on which is mounted a standard 2 arranged to provide spaced bearings 3, 3, preferably of the antifriction type. Thebearings 3, 3, support a shaft 4, one end' portion of which outwardly of the standard 2, carries a drum, indicated as an entirety at 5. Intermediate the bearings 3, 3, the shaft 4 is provided with a gear 6, in mesh with a pinion 1', which is drivingly connected through a suitable reducing gear mechanism within a housing 2; to ashaft B, the latter in turn being driven by a suitable motor 9. It) indicates a magnetic brake operable to stop the motor when current thereto is shut 01f. The sheet material A issupplied to the drum'5 for coiling thereon from anysuitable source (not shown). The drum 5 is supported above a pit ll having a track for .asuitable truck I2, which may be positioned be- .low' the coiled material-A, the truck 12 having an 'elevatable 'sectionlZa which is adapted to be raised into engagement with the coil (see Fig. 2) and thereafter, by means'of' a-plunger l3 con- .nected to a piston within a cylinder I4 (the latter in turn being connected with a source of fluid supply under pressure), the coil A maybe moved away from the drum 5 for transfer to a platform I5; The truck l2 and means for moving it form .nopart of the'present invention, for which reason more details of construction thereof are omitted. The drum- 5 comprises. a main section IE, to which front and rearlheads l1, Ila; are secured by cap screwsiB, .and collapsible sections l9, I9, I 9, Each of the drum sections [9, 19, on its inner wall and adjacent'itsopposite ends and intermediate thereof, is providdwith webs Isa terminating at thatend adjacent to the main section lfiin'alined hollow bosses .20, through which a rod or shaft-.2! extends topivotally support the The drum section I9 is arranged intermediate walls 29 and inclined slots 39 and its upper end is provided with strips 3|, each related to the adjacent cut away and slot to form a guide having an inclined portion and a horizontal portion forming therewith slot sections 32, 32a. 33, 33 indicate a pair of operating devices mounted in thewalls of the drum section I9'and engaged by the walls of the slot sections 32, 32a, to move the drum section I9 outwardly and inwardly. Each of the devices 33 comprise a roller 33a arranged to engage the walls of the adjacent slot sections the free ends of the sections I9,;I9, its opposite:

lateral portions being connected to the sections Z by pairs of links 23, by means of ,which thesection I9 is supported on tl'iesections- I9, I9,. but

free to move radially of thedrum 5'. The opposite ends of the drum section I9 slidably fit radially disposed recesses II formediin' the heads'I'I, I'Ia (see Fig. 8). The side walls of the drum section I9 are inclined downwardly and outwardly and serve as cams for engagement with the free ends of the sections I9, I9, so that when the section I9 is moved outwardly radially, by the mechanism hereinafter referred to, it swings the sections I9, I9, outwardly, whereby the sections I9, I9, I9, are positioned to form with the main section I 6 a cylindrical wall (see Fig. 5) on which the material may be coiled. In the movement of the drum section I9 inwardly, it operates through the links 23 to swing the sections I 9 into their collapsed position.

24 indicates a device for securing the free end of the sheet material to the drum section I6,

mounted thereon and provided with a material engaging member 24a. Asshown in Figs. 5 and 6, the wall of the drum section I3 is formed with a slot or opening ISr which extends from end to end of the drum section, to receive the outer or free end of the material, and the wall of the section is formed with a recess, in connected relation to the opening 16w; the bottom wall of the recess forming an abutment I6a2' in opposed relation to the material engaging member 24a, so that when the latter is operated, as later set forth, the material A is clamped or gripped between the abutment I6zn' and member 24a. The device 24 comprises a rocker preferably. shaped to provide two spaced sleeves 24b rotatably fitting that rod 2| remote from the abutment like, each sleeve having (a) integral arms 240 preferably integrally connected to the material engaging member 24a and (b) a separate, operating arm 24d. Each arm 24d is recessed inwardly from. its outer end, as shown at 24d, the wall of the recess being threaded to receive a pin 25, the outer end portion of which forms a; shaft fora roller 26. The roller 26 is held 'in position on the shaft by a nut 26a. The peripheries of the rollers 26 are rounded in cross section for a reason which will later be apparent. The purpose of the arms 24d will later appear. 1

21 indicates as an entirety means for operating the drum sections I 9, I 9, I9. and device 24. 'Of the

means

21, 28 indicates a sleeve slidably fitting the shaft 4 within the drum 5 for movement thereon in opposite directions by a fluid operated means, indicated as an entirety at 28'. The sleeve 28 is provided on its upper side with a radially extending wall 28a arranged to project into a recess 28a formed in the drum section I9. As shown in Figs. 4a, 5 and 6, the recess 28a permits the drum section I9 to move upwardly and downwardly relative to the wall 28a for reasons later apparent. The wall 280,, adjacent its opposite ends is cut away to form horizontal -32,'32 1,-and oppositely extending shafts 33b rotatably fitting openings 330 formed in the side portions of the drum section I9. As the devices 33'are, supported on the drum section I9, it will be seen that when the sleeve 28 is moved toward the right, as viewed in Fig. 4a, the drum section l9'swill be moved outwardly and it in turn will swing the sections I9, I9, outwardly; and when the sleeve 28 is moved in the opposite direction,

the drum section I9 will be moved inwardly and it in turn through the links 23 will swing the sections I9 inwardly. The sleeve 28 is also provided with a laterally extending wall 34 formed with elongated slots 35 (one being shown in Fig. 9) inclined to the axis of the drum 5 to form cams for the rollers 26. As shown in Fig. 9, the

adjacent roller 26 engages the walls of the slot, the effect of which, upon movement of the sleeve 28 toward the right as viewed in Fig. 411 (downwardly as viewed in Fig. 9), is to operate the rocker 24; thatls, to swing the arm 24d outwardly and the material engaging member 2411, in the opposite direction. Accordingly, if the free end of 'the'material A'has been inserted in the opening Him, the member 24a will engage and grip the material against the abutment I612; and upon movement of the sleeve in the opposite direction, the walls of the slot 35 will operate the rocker 2 I in the opposite direction to release the material. From the foregoing description it will be seen that the movement of the sleeve 28 in either direction serves to operate the drum sections and the rocker 24. It will be understood that in the operation of the sleeve 28 toward the right, the drum sections are moved into their expanded position as the rollers 33a reach the upper end of the inclinedslot sections 32 and are maintainedin this position as the rollers-33a 50 :move-through the slot sections 3241.

It will be noted that in the movement of the sleeve 28 to effect a translation of the wall 28a relative to the rollers 33a, the sleeve 28 is also, through the engagement of the walls of the guide slots 35 with the rolls 26, simultaneousl operating the rocker 24 to move the material engaging member 24a toward the abutment Ifisc; however, as the slots 35 have a predetermined 'relalation, as to length and inclination to the axis of the drum 5, the material engaging member 24a engages with the material A to grip it against the abutment IBx' at or following the entrance of the rollers 33min the slot sections 32a. That is, as the rollers 33a traversethe slot sections '32 from the position a to the position b (Fig. 4a)

to move the drum sections I9, I3, I9, into their -slot s-ections 32a, the rollers 23 move from the position b to the position shown in full lines (F g. 9), this latter movement ofthe rollers 26 serving to move the member 24a into clamping engagement with the material. In this arrangement, the movable drum sections l9, l9, 19', are moved into their final position in advance of thegripping of the material and thereafterthe pressure of the fluid operated means 28 operates to force the material engaging member 24a into engagement with the material A to thus secure the latter against the abutment 161:. In the final movement of the rocker 24, it is directly connected to the fluid operating means 28'. This arrangement and operation permits the material engaging member 24a to readily and effectively clamp material of different thicknesses against the. abutment 16w so that the provision of adjustable devices for the member 24a or between the sleeve 28 and rocker 24, within certain limits as to the thicknesses of the material, are eliminated. The sleeve 28 is provided on that side opposite to the wall 34 with a flange 34a arranged to engage a portion of the main drum section 16 (for example, an upwardly extending wall Hi") to resist any torque efiect on the sleeve 28 due to the co-action between the rollers 28 and side walls of the guideslots 35 in the movement of the member 24a to secure the material to the abutment Him.

The fluid operated means 28 is arranged, as later setforth, to move the sleeve 28 inwardly, so that in such movement, the material engagement member 24a is positively disengaged from the material A in advance of the movement of the drum sections l9, l9, l9, inwardly, since the rollers 33a must traverse the slot sections 32a before they enter and ,traverse the slot sections 32. opening 411 in the shaft 4 and serving as an operating connection between the piston 38 of the fluid operating means 28' and the sleeve 28. At its outer end, the rod 31 is provided with screw threads threaded into a head 31a, the outer portion of the shaft opening 4a being enlarged to accommodate the head; and the head 31a in turn is provided with a diametrically disposed pin 39 the opposite ends of which extend through diametrically related, elongated slots 40 formed in the shaft 4 and flt into recesses 48a formed in the sleeve28 so as to connect the rod 31 to the sleeve. The slots-49 are elongated to permit movement of the pin 39 by the rod 31 in either direction to operate the sleeve 28. By threading the head 311; on the outer end of the rod 31, the rod may be rotated, the effect of which is to adjust the head endwise of the rod, such adjustment through the pin 39 and sleeve 28 serving to adjust the slot sections 32 relative to the rollers 33 and slots 35 relative to the rollers 28. As shown in Fig. 4, the 'rod 31 extends beyond the inner end of the shaft 4 for connection with the piston 38, which reciprocates within a cylinder 38'. The cylinder 38' consists of a side wall 38a and inner and outer heads 38b, 380, the inner head 38bbeing rigidly connected by a collar 4| (through which the rod 31 extends) to the inner end of the shaft 4, whereby the latter rotates the cylinder. The outer cylinder head 380 is suitably bolted to the outer end of the cylinder side wall 38a and formed with an opening, which is axially related to the shaft 4 and forms the seat for the inner flanged end of a conduit member 42. The member 42 extends outwardly from the head 380, a ring nut 42a threaded thereon and tightened against the head 38c serving to secure the member 42 thereto for rotation with the cylinder 38. The conduit member 42 extends into and through a casing 43 for'rotation therein to provide for the. supply 31 indicates a rod extending through the 1 of the fluid, such as oil or air under pressure, to the cylinder 38' and its discharge therefrom through stationary pipes 44, 44a, dependent upon theposition' of the valve element of'a valve indicated as an entirety at 45. The pipe 44 is connected to an opening leading through the side wall of the casing 43 into an annular recess 46 formed in its inner wall and connected to one end of a conduit 460. formed in the conduit member 42, the opposite end of the conduit 46a leading into the outer end of the cylinder 38', so that when the fluid is supplied from the pipe 44 to the conduit, 460 it will move the piston 38 inwardly (to the right as viewed in Fig. 4) and through the rod 31 operate the sleeve 28 outwardly. The pipe 44a is connected to an opening leading through the side wall of the casing 43 into an annular recess 41 formed in its inner wall and connected to one end of a conduit 41a formed in the conduit member 42, the opposite end of the conduit 410. being connected to one end of a duct 48 formed in the cylinder head 38c and side wall 38a of the cylinder 38'. As shown in Fig. 4, the opposite end of the duct 48 leads through the cylinder head 382), so that when the fluid is supplied from the pipe 44a to the conduit 41a and duct 48, it will move the piston 38 outwardly (to the left as viewed in Fig. 4) and through the rod 31 move the sleeve 28 inwardly.

The valve 45 serves simultaneously to connect either pipe 44, Me, with a fluid supply pipe 44' and the other pipe with 'a discharge =pipe 44a, dependent upon the position of the valve element 45a of the valve 45. As shown in Fig. 4, the valve element 450, is provided with passages 45b, 45c and 45d. In the position shown, the passage 45c connects the supply pipe 44' to the pipe 44 and the passage 45b connects the pipe 44a to the discharge pipe 44a. Upon movement of the valve element 45a bya rod 49 to the right (as viewed in Fig. 4), the passage 450 will connect the supply pipe 44 to the pipe 44a and passage 4511 will connect the pipe 44 to the discharge pipe 44a, The end walls of the valve casing are preferably utilized to limit the movement of the valve element in either direction with the passages therein in registry withthe pipes in either operated position. Accordingly, in either position of the valve element 45a, the fluid will be supplied through one pipe to one side of the piston 38 and the fluid on the other side thereof will be discharged from the cylinder 38' through the other pipe.

The casing 43 is; mounted on the conduit member 42 between a shoulder thereon and the head of a screw 43' threaded into the outer end of the conduit member. The casing 43 consists of a substantially annular side wall and inner and outer end walls 43a, the side wall being lined with packing material in which the conduit member 42 rotates.

In operation, the free end of the material A is inserted in the slot lfia: and then fluid is admitted to the outer side of the piston 38, the movement of which toward the right as viewed in Fig. 4 serves to effect an expansion of the drum sections I9, l9, l9 and then a'gripping of the material. The motor 9 is then operated to coil the material on the drum 5. To remove the coil, the piston 38 is operated in the opposite direction, to disengage the member 24a from the material and collapse the drum sections. The truck 12 is then moved on the rails to position its platformbelow the coiled material. The platform is then raised intoengagement with the coil, following which the plunger l3 engages the truck and coil and moves the coil beyond the drum 5. for transfer to the platform [5.
