SPECIFICATION forming part of Letters Patent No. 759,362, dated May lO, 1904.

'Application mea March 14, 1902.

To all whom t may concern.-

Be it known that I, WILLIAM FRANCIS, aciti- -zen of the United States, residing at No. 535 Hermitage street, Roxborough, Philadelphia, Statexof Pennsylvania, have invented certain new and useful Improvements in Willows, of which the following is a specification, reference being-had therein to the accompanying drawings.

My invention relates to improvements in the machine technically known as a willow, in which certain gearing and mechanical movements operate to automatically feed the willow with ber or other material to be beaten, opened up, and cleaned and to automatically discharge same when cleaned, the object of my invention being to improve said feeding and discharging mechanism by providing better and more economical mechanical movements for said feed and discharge mechanism. This objectI attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which-- Figure l is a longitudinal section of the willow. Fig. 2 is a side elevation of same. Fig. 3 is a plan view of the feed mechanism. Fig. 4 is a detail view of the feed mechanism.

The machine known as a willow consists of a casing a, having appropriate bearings for a transverse shaft a', upon which is mounted a drum a2, consisting, usually, of a series of hollow arms with projecting teeth a3 at their outer ends, the drum being rotated and the teeth a3 of the same cooperating with certain fixed teeth and perforated or slotted segmental screens a5 and a operate to open or loosen up, beat, and remove thedust or dirt from the masses of ber subjected to the action of the machine. With the machine are usually combined an exhaust-fan a pair of feed-rolls c c', a conveyer-belt CZ for carrying the masses of uncleaned liber to the feed-rolls, and a pivoted discharge-door f at the bottom of the machine, through which the cleaned and separated masses of fiber-are discharged. The shaft a has the usual driving-pulley as and the pulley b for receiving the belt b2 to drive the fan It also has the pulley c2 to receive the belt c3 to drive the pulley c4, which Serial No. 98,213. (No model.)

isfree to revolve on the stud c5, Figs. 3 and 4, and has secured to its hub the gear c, which is in gear with the gear c7 of the shaft cs.- The stud 'c5 is secured in the slot 09 of the stand 01 and is adjustable to permit gears of different diameter being substituted for the gears c and c7 to vary the number of revolutions of the shaft cS for each revolution of the shaft a. The shaft o8 has suitable journals which are secured to the casing a and carries the bevel-gear c3", which is in gear with a similar bevel-gear o, securedA to the worm cl2, which is mounted. in the journals elf c, The worm cl2 is in mesh with the worm-wheel 015, l,secured to the hub of the disk 016. The disk 01 revolves on the stud 017, secured to the casing a, and has a segmental rack c on its rim. It is also provided with a projecting pin 01 on its outer face. The segmental rack on the disk ci moves in a clockwise direction and .meshes into the pinion 020, secured to the shaft of the lower feed-roll c. The stated direction of movement of the rotating rack acts to hold the feed-rolls firmly in their bearings and reduces jarring and frictionand Wholly obviates breakage of the gear-teeth. On the opposite end of the shaft of the feed-roll c is secured the gear 021, which is in gear with a similar gear 622, secured to the shaft of the upper feed-roll c. To the shaft of the lower feedroll c is secured the gear o23, vwhich is in gear with the follower-gear 024, mounted on a suitablestud secured to the casing. The followergear c2* is in gear with the gear d', secured to the driving-shaft of the conveyer-belt CZ.

The discharge-door f is secured to the shaft f and is held in the closed position by the weight f2. The sprocket-wheel f3 is mounted on and free to revolve on the stud f4, secured to the casing of machine. Theqsprocket-wheel f5 is secured to shaft f and is connected by sprocket-chain f6 with sprocket-wheel f3, Sprocket-wheelf3 is provided with the arm f7, which is provided with shoe f 1 to make contact with the projecting pin c1 on the disk o16.

7L is a relief-valve to admit air into the willow to supply fan when the discharge-door f is open and liber is being discharged. It is connected by the chain f with the arm fm, secured to the sprocket-wheel f5, which is secured to the shaft f of the dischargedoor f., said relief-valve /t being opened simultaneously with discharge-door f.

In the operation of the machine, the discharge-door f being held in the closed position by the weight f2 and the relief-valve L being closed, a quantity of liber is placed on the conveyer-belt CZ. The worm cl2, being rotated through the medium of the pulley 0*, gears c and c7, shaft cs, and bevel-gears c3 and c, revolves the worm-wheel cli and disk el in the direction of the arrow, Fig. 2. The'segmental rack c1S on the disk o16 rotates the pinion 020 and the lower feed-roll c in the direction of the arrow, Fig. 2. This motion being downward causes the lower feedroll to vrest firmly in its journals, preventing its raising up and getting out of gear, as in other machines of this class. The gears 021 022 on the opposite ends of the feed-rolls rotate the Lipper feed-roll and the gear 023 on the shaft of the lower feed-roll @through the medium of the idler-gear 0%, and the gear d moves the feed-belt d, carrying the fiber placed thereon to the feed-rolls to be fed into the willow-and brought into contact with the revolving teeth as and stationary teeth to be beaten, opened up, and cleaned, the coarse dirt falling through the screen a5 to be removed through the door am, the fine dust or dirt being drawn through the fine screen d by the fan I). The segmental rack c is of such length-as to revolve the feed-rolls a sufiicient length of time to introduceinto the machine sulicient fiber for a charge. After the segmental rack has ceased to revolve the feed-rolls the pin el, which is placed at a point in the rearl of the segmental rack to allow suicient time for the ber fed into the machine to be thoroughly treated, makes contact with the shoe f1 on the upper end of the arm f7, attached to the sprocket-wheel f, causing same to revolve on stud f* and by means of sprocketchain f imparting motion to sprocket-wheel f5, secured to shaftf, opening discharge-door j', allowing treated fiber to be discharged. At the same time the chain L/ of the relief-valve 7L, being connected to arm f 12, is drawn down, opening relief-valve L, ad-

mitting air to the anb to allow a free discharge or' dust, &c. The shoe f1 is of suBcient length to hold the discharge-door open until the treated ber is discharged. The operation is completed in one revolution of the disk om, the time of each revolution being Varied by a change of the gears c7 and 0S to suit the material being treated.

Vhat I claim, and desire to secure by Letters Patent, is# v The combination of a willow having' a discharge-door, a suction-ian, a valve for admitting air to the casing to supply said-fan, and means for simultaneously opening the discharge-door and valve, said means comprising a worm, a shaft, a Worm-wheel on said shaft in position to engage the worm, a disk on said shaft provided with a projecting pin, a stud, a sprocket-wheel thereon provided with a shoe disposed in the path of said pin, a shaft carrying the discharge-door, and means for maintaining said door closed, a sprocketwheel on said last-mentioned shaft, a chain connecting said sprocket-wheels, an arm on said last-mentioned shaft,` and a flexible connection between said arm and valve, substantially as described.

In testimony whereof I aiix my signature in presence of the witnesses. WILLIAM FRANCIS.
