3 Claims.
The principal objects of this invention are to provide an improved retractable chuck for supporting a web roll or the like and to provide simple means for operating the retractable chuck which is carried in one of the spiders of facilitate the mounting of the paper rolls.
This application is a division of application Serial No. 706,794, filed January 16, 1934.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings, in which Fig. 1 is an end elevation of a web roll supporting chuck comprising a preferred embodiment of this invention;
Fig. 2 is a sectional View of the retractable chuck mechanism, and
Fig. 3 is a sectional view of the same on the line 33 of Fig. 2.
A simple means is provided for operating each retractable spindle l2 which is carried in one of the spiders 9 of the reel to facilitate the mounting' of the paper rolls. The spider 9 has a hole 45 bored in the end of each of its arms for the mounting of the chuck 46. A keyway 41 in this chuck cooperates with a guide pin 48 to permit short longitudinal motion but to prevent any rotatable motion of the chuck. A worm 49 is centrally located in chuck 46 and has one end supported in a hole 50 and the other carried in plug 46 which is held in place by a screw 52, half in the plug and half in the chuck. A hand wheel 53 is pinned to the outside end of the worm 49 for the purpose of rotating it. The worm 49 meshes with a gear 54 on a transverse shaft 55 mounted in bushings 56 and 51 on the spider 9. On one end this shaft has attached to it a collar 58 and on its other end is an operating arm 59. This arm 59 carries a retractable dowel 60 which may be operated by a handle 6! against the opposition of a spring 62. A plate 63 is secured to the spider 9 and provided with a hole 64 to receive the dowel pin. When the dowel pin is inserted in the hole 64 the chuck is then in its operative position and stays in that position. This places the spindle I2 in the dotted line position in Fig. 3.
The outer race of a ball bearing 65 at the end of the chuck 46 is secured to the spindle [2 by a Washer 66. The inner race is carried on the chuck 46 and secured thereto by a Washer 61. Of course, a similar construction is provided on each arm of the spider. Therefore, it is .apparent that the spindles carried in the opposite spider may be stationary longitudinally but rotatable on their axes. Also when the arm 59 is moved to such position that the dowel 60 enters the hole 84 the hand wheel 53 will be free to be turned to move one of the spindles l2 toward or from the paper roll in an axial direction. This constitutes a simple construction so that a finer regulation of the rotatable chucks may be obtained by a single means.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I do claim is:-
1. In a web roll supporting reel, the combination with the reel, of a movable chuck for supporting one end of the web roll, a non-rotatable but axially slidable member having bearings for supporting the chuck rotatable thereon, a worm rotatable in said member, a shaft, means connecting the worm with the shaft, a handle on the shaft, and a retractable pin in the handle, the reel having a recess for receiving the pin for the purpose of holding the shaft in its adjusted position, whereby the chuck may be moved axially to an advanced position and held in such position.
2. In a chuck mechanism for supporting a web roll, the combination with a framing and a nonrotatable longitudinally movable chuck mounted therein, of a worm rotatably mounted in said chuck, and a Worm-wheel rotatably mounted in said framing and cooperating with said worm to provide longitudinal motion of the chuck with respect to the framing.
3. In a chuck mechanism for supporting a web roll, the combination with a framing and a movable chuck carried thereby, of a worm rotatably mounted inside the chuck but incapable of a relative axial motion therein, a worm wheel on a transverse axis, projecting into the chuck, and meshing with the Worm for moving the chuck rapidly, and a hand wheel on the worm for adjusting the chuck.
