GEARING.

eeaaoo.

To all whom it may concern:

Be it known that I, Gnonon CARTWRIGHT, a citizen of the United States of America, residing at Paterson, New Jersey, have invented certain new and useful Improvements in Gearing, of which the following is a specification.

My invention relates to web winding machines and has especial reference to mechanism for accommodating the surface speed of the receiving or take-up spool to the quantity of material wound upon the same.

The invention is generally applicable to machines wherein the speed of a rotating member is to be regulated, and in the following description and accompanying drawings, a concrete example of the invention as applied to web winding machines is given.

A clear understanding of the invention will be facilitated by the accompanying drawings, wherein Figure l is a side elevational view of a web winding machine with the invention applied thereto; Fig. 2 is an end view of a special form of clutch mechanism and related parts, certain of the parts beingin section; Fig. 8v is a top plan view of the clutch; Fig. 4 is a vertical sectional view thereof; and Fig. 5 is a bottom plan view of. the same.

Referring by reference characters to the several parts of the mechanism shown in the drawings, 1 designates the frame of a finishing or web winding machine adapted to wind upon the spool 2 silk or cloth with a web of paper between the windings of the material. The silk or cloth 3 is fed over the guide roller 4 from any suitable source (not shown) to the spool 2 and the papen insert web is preferably provided in the form of a reel 5 revolubly held in a bracket 6, and passing over guide and tension rollers 7 to 11 to the spool 2.

Secured to the frame 1 of the machine is a bracket 12 provided at its free end with a sleeve 13 in which a pair of revoluble shafts 14 and 15 bear, the opposite ends of the shafts being journaled in sleeves 16 and 17 respectively, suitably secured to brackets 16 and 17 a on the machine frame. The shaft 14 is slotted at one end to receive a pin 18 projecting from the end of the shaft 15, the construction being so devised that the shafts are caused to revolve in unison, but in op- Speeifieation of Letters Patent.

Application filed June 1, 1909.

Patented July 19, 1910. Serial No. 499,496.

posite directions by the mechanism hereinafter described.

The mechanism for revolving the shafts 14 and 15 is preferably constituted as follows z-Represented in dotted lines in Fig. 1 is a belt pulley wheel 19 upon whose shaft (not shown) is rigidly secured a main power disk 20 which when revolved is designed to impart rotary motion to friction disks 21 and 22 carried by the shafts 14 and 15 and contacting with the disk 20. The shaft 15 is provided with a key-way 28 into which projects a key 24 passing through a sleeve 25 secured to or formed integrally with the disk 22. The latter is designed to be moved along the shaft 15 to any point thereon and set through the medium of the key 24, thus initially determining by its distance from the center of the power disk 20, the speed at which the shafts 15 and 14 shall revolve. The shaft 14 is provided with a rib 26 which engages a slot formed in the friction disk 21, the latter however, being designed to travel along its shaft, as contradistinguished from the disk 22 which remains set. The longitudinal movement of the disk 21 on its shaft regulates, through the action of a train of gears about to be referred to, the speed at which the take-up spool 2 revolves.

At its free end the shaft 14 carries a bevel gear wheel 27 meshing with a gear wheel 28 which forms one of a train of gears 29 to 33 designed to drive the spool 2 upon which the fabric and paper are wound. It will be apparent that when the friction disk 21 is at the periphery of the power disk 20 the speed of rotation of the friction disk will be its maximum and the speed of rotation of the spool 2, through the medium of the gear train, correspondingly high, and as the disk 21 moves toward the center of disk 20 the rotary speed of the former will decrease effecting a corresponding decrease in the rotary speed of the spool 2.

J ournaled in sleeves 34 and 35, carried, respectively, by the brackets 16 and 17 is a spindle 36, which is threaded for about one half its length. The spindle 36 is above and parallel to the shafts 14 and 15 and is driven from the latter through the medium of. a train of gears consisting of spur wheels and pinions 37 to 40. Engaging the threaded portion of the spindle 36 is a divided nut designated generally as C having'a depending arm 41 which reaches into a slotted collar 42 secured to or formed integrally with the friction disk 21, and as the divided nut C travels along the spindle 36, the arm 41 conveys the disk 21 along its shaft 14.

The detail structure of the divided nut is clearly illustrated in Figs. 2 to 5 to which reference will now be made.

The divided nut shown and described in the present application is not herein claimed but forms the subject matter of a co-pending divisional application filed February 2nd, 1910, Serial Number 541,507, and the preferred form of such divided nut includes a carrier frame comprising a substantially rectangular plate 42 and the annular side members 43 and 44 designed to engage the shaft 36. As will be noted from Figs. 3 and 4 the plate 42 is provided with an elongated slot 45 designed to receive the bases 46 and 47 of the semicircular jaws 48 and 49, the connection between the bases 46 and 47 and plate 42 being in the nature of a mortise and tenon joint. The lower face of each base is provided with an eccentric curved slot 50 designed to receive pins 51 arranged at diametrically opposite points upon a circular plate 52 (revoluble in an undercut part of the plate 42) formed rigidly with a short shaft 53 upon which the sleeve 54 of an operating crank handle 55 is secured.

hen the crank handle is parallel to the spindle 36 the pins 51 rest in the lower ends X of the slots 50 and the jaws 48 and 49 of the nut are closed and embrace the screw spindle 36. hen the crank handle is moved, by mechanism to be hereinafter described, to a position perpendicular to the spindle 36 the pins 51 are moved to the opposite end y of the slots 50, and compression springs 56, arranged in slots 57 in the jaw members, unfieX and force the jaw members apart causing them to release engagement with the spindle 36.

Provided upon the forward face of the plate 42 is a spring pressed latch 58 (Figs. 2 and 3) having a projecting end 59 designed to engage a lug 60 formed upon the inner face of the crank handle 55. Pivoted to the depending arm 41 of the nut C is a pawl having one arm 61 extending into a semicircular slot 62 on the lower face of the latch 58 and the other arm 63 projecting into the path of a cam 64 formed on a collar 65 designed to be secured, by means of set screw 66, to the spindle 36. It will be understood that when the cam nose 64 revolves and strikes the arm 63 of the pawl, the other arm 61 will draw the latch out of engagement with the lug 60 permitting the springs 56 to unfieX and cause the pins 51 to travel in the slots 50 thus permitting the jaws to open.

Following is a brief description of the operation of the entire mechanism :As-

suming the several parts to occupy the positions shown in Fig. 1 and power applied, the spindle 36 will revolve feedingforward thereon toward its center the nut C. The depending arm 41 of the latter engaging the collar 42 will move the friction disk 21 toward the center of the power disk 20 thus, through the gear train 27 to 33 decreasing gradually the speed of the spool 2. TV hen the nut 0 reaches the center of the spindle 36 the cam 64 of the collar 65 will strike pawl arm 63 causing release of the latch 59 from the lug 60 and thus permitting the springs 56 to unfiex and force the jaws 48 and 49 apart, in doing which the plate 52 is revolved and the pins 51 move from ends X to ends Y in the slots 50 and the crank handle is turned to a position perpendicular to the spindle 36. The aws are then opened and out of engagement with the spindle 36 and no further movement of the divided nut or of the friction disk 21 occurs. When it is desired to rengage the jaws with the spindle 36 the crank handle 55 is turned, causing the plate 52 to revolve and the pins 51 to ride in the slots 50 back to the position X thus bringing the jaws together about the spindle, and when the latch 59 is again in engagement with the lug 60 the parts are locked in position and remain so until the cam 64 is again encountered by the pawl arm 63.
