Abstract
536,884. Feeding webs. BENNETT, T. R. Nov. 27, 1939, No. 30919. [Class 100 (i)] In a web roll support for a printing machine &c. in which the roll is supported on end bungs, each bung is movable axially in its support by mechanism allowing of both a quick and a slow motion of the bung and at least one of the bungs is associated with a brake for the roll. In one form, Fig. 3, the bung spindle 1 is rotatable but not axially slidable in a sleeve 6 which is rotatable and axially slidable in the end 7 of the usual three-armed spider A. The sleeve 6 is provided with a cam groove 12 at one side and teeth 8 at the other side engaged respectively by a pin 13 eccentrically disposed on the end of a spindle 14, and a worm 9 on a spindle 10. By rotating the spindle 14 by a handle 15, the sleeve 6 and with it the bung spindle 1 is moved axially at a rapid rate and by turning the spindle 10 by a handle 11, the sleeve 6 is rotated, the action of the cam groove 12 on the stationary pin 13 causing a slow axial movement of the sleeve and spindle 1. To prevent accidental turning of the handle 11, it is loose upon the spindle 10 and is formed with a cam groove 19 engaged by a spring pressed latch 21 mounted in a sleeve 22 which is slidable axially on the spindle 10 and in a sleeve 22<SP>1</SP>. A pin 24 engages in the sleeves 22, 22<SP>1</SP> and in a fixed bush 23 and is in two parts, the dividing plane 25 between the parts being held normally by a spring 26 above the plane of contact of the sleeve 22' and flange 27 of the bush 23. When pressure is applied to the handle 11, the latch 21 is first depressed carrying the sleeve 22 with it until the plane 25 lies in the plane of the contact of the sleeve 22<SP>1</SP> and flange 27 after which further movement of the handle is transmitted through the latch 21 to the spindle 10. The handle 15 is locked against accidental movement by a somewhat similar construction but the sleeve 14<SP>1</SP> carrying the latch 21 carries a transverse pin 27 normally held by springs 28 in a recess in a fixed bush 29, and is drivingly connected by pins 14<SP>2</SP> to a block 14<SP>3</SP> fixed to the spindle 14. One side wall of the recess is longer than the other and forms a stop to limit the rotation of the spindle 14 to 180 degrees. By applying pressure to the handle 15, the latch is moved sufficiently to move the pin 27 clear of the shorter wall of the recess to allow rotation of the spindle through the latch 21 and pins 14<SP>2</SP>. The spindle 1 extends beyond the arm A on the side opposite to the roll and is slidably keyed to a brake drum held against axial movement by a flanged ring secured to the side of the arm A. In a modification, Fig. 6, the sleeve 32 is held against rotary movement and, instead of the gearing 8, 9, the spindle 1 is moved at a slow rate by an axial screw 36 threaded into the end of the spindle 1 and rotatably held by members 34 on a sleeve 30 rotatable in but not axially movable relatively to the sleeve 32, and in which the spindle 1 is slidably keyed. The brake drum 16 is slidably keyed to the sleeve 30 but is held against axial movement. Accidental movement of the screw 36 is prevented by providing its operating hand-wheel 38 with a pin 41 normally held by a spring 42 in the slot in a member 43 fixed to the brake drum. In a further modification, the screw 36 is fixed to the spindle 1 and the hand-wheel 38 is in the form of a nut. In this construction also, the brake drum is mounted on a spindle parallel to the bung spindle 1 and driven by gearing therefrom. The spider arms A are mounted on a supporting spindle and may be adjusted separately according to the width of the rolls or together for main " side-lay " adjustment. Additional side-lay adjustment is effected by the bung at the opposite ends of the roll.
