TIMOTEO VILLAMOR, OF MERIDA, MEXICO.

MACHINE FOR PREPARING VEGETABLE FIBER.

SPECIFICATION forming part of Letters Patent No. 559,009, dated April 28, 1896.

Application led February 23, 1894. Serial No. 501,138. (No model.)

To all whom. t may con/cern:

Be it known that I, TiMoTEo VILLAMOR, of Merida, Yucatan, Mexico, have invented a certain new and useful Improvement in Ma-l chines for PreparingVegetable Fiber,of which y the following is a specification. Y

I -will describe a machine embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure l is a side elevation of a machine embodying my improvement. Fig. 2 is a front view of the same. Fig. 3 is a plan or top view of the same. Fig. 4 is a horizontal section of a certain portion of the machine. Fig. 5 is a vertical section at the plane of the line 5 5, Fig. l.

Similar letters of reference designate corresponding parts in all the figures.

A designates the frame of the machine. It may be made of any suitable construction and materialas, for instance, suitable heavy timbers bolted or otherwise fastened together.

B designates a rotary support for the scrapers B, (here shown as made in the form of a wheel,) that may be of any suitable form and affixed to a shaft B2, that is journaled in bearings in the frame A. Preferably the bearings may be adjustable horizontally under the influence of screws B3, impinging against the bearings and connected with fixed brackets B4 by means of nuts B5, arranged on opposite sides of the brackets.

C designates a curved table. It may be made of any suitable materialas, for instance, a metal backing c" and a facing of wood c2, the wood facing being extended at the ends over the ends of the metal backing. This table is made in two independent sections, which are arranged side by side and curved longitudinally to substantially conform to the curve of the rotary support B, so that the edges of the scrapers will all pass equally distant from the table during the rotation of the rotary support B.

The table O is adjustable at both ends. Under the lower end of each section is a roller or bar C', which is supported in a frame, c3, pivoted by means of a pin c4 to brackets c5, erected upon the frame A. The frame c3 may be adj usted upwardly or downwardly by means of a screw c6. The latter is driven through the agency of miter-wheels c7 c8 and a shaft e9, extending to the front of the machine and provided at its extremity with a hand-wheel 010. The upper end of each section of the table is pivoted at the rear side by means of a pin c11 to a block cl2, tted to slide in brackets cl3. This block maybe adjusted forwardly and rearwardly by means of a screw 014, engaging with a tapped hole in the block and fitted in abearing C15, supported by the brackets cl3. The shank of the screw has a hand-wheel o16 at the front of the machine.

It will be seen that by the construction described a very perfect adjustment ofthe table and its two ends may be made, and that after adjustment the ends of the table will be held firmly in position.

Above the table C is an endless chain D, composed of links which are pivotally connected together by horizontal pins and each of which is provided with a groove in the upper surface. This chain runs around wheels or pulleys D D2 D3. The wheels D' D2 are mounted upon shafts d d2, that are j ournaled `in bearings supported by the brackets C18.

Only the shaft d is driven, the shaft d2 being adapted to run idly.

Motion may be imparted to the shaft d by means of a belt or sprocket-chain d2, extending from a pulley d4 on said shaft d to a pulley d, affixed to a shaft D4. driven by bevel-gears d6 from a shaft D5, supported in bearings fastened to the frame A.

`The shaft D5 is provided with fast and loose pulleys @Z7 d8, the pulley C17 being the fast pulley. A belt (Z9 extends from the pulley d7 or the pulley d8 to apulley d10, affixed to the main shaft B2.

A pulley b2 on the shaft B2 is intended to receive motionthrough a belt from any suit'- able source of power.

The wheel D3 is mounted upon a shaft d, journaled in bearings e112, that are fitted in housings fastened to the frame A. Above these bearings are springs d, which may be adjusted by means of screws d, extended through the hub. These adjustable bearings allow for a yielding of the chain whenever necessary.

Preferably the pulleys D D2 Da will be flanged, so as to hold the chain D in place laterally.

The shaft ID4 is IOO E designates a bridge extending between the brackets y@wand curved on its upper surface to correspond with the rotary support B and the Scrapers affixed thereto. This bridge has an upwardly-extending flange e on the lower side, or, in other Words, that side which is the nearer to the Scrapers. It is not inftended that the under side of the upper portion of the chain shall rest upon this bridge; but, on the contrary, it is intended that this portion of the chain shall be lifted above the bridge, the-only purpose of the bridge being to prevent ihe chain from being drawn toward the Scrapers and this function being fulfilled by the impingement of the flange e against the rear side of the chain.

F designates a wheel supported in bearings fitted in housings f and im pelled downwardly by means of springs f This wheel is grooved `in its periphery so as to intermesh with the goooveof the chain D, as may be best understood by referring to Fig. l. As the chain has one groove and the wheel another, it will be seen that I provide a number of bearingsurfaces for leaves which will be presented between the chain and wheel and subjected to the action of the Scrapers.

The shaft d2 derives motion from the chain D acting upon the Wheel or pulley D2. On said shaft LZ2 is affixed a bevel gear-wheel (X15, and this engages with a bevel gear-Wheel g, affixed to a shaft G, journaled in bearings on an extension A of the frame. A.

The extension A of the frame A will preferably be horizontal and about on the level with the, meeting'surfaces of the chain D and wheel F. A shaft Gis alsov journaled in the extension A. The shafts. G G are provided with pnlleysg' g?, and beltsy or sprocket-chains gpass around these pulleys, formingtogether a supporting-carrier for the leavesiWhic-lr are to be fed between the chain D and wheel F. The ends of the leaves will be` fed automatilcal-lyto thechain D and'wheelF and willzbe carried along by. thel latter acrossv the' table C, and; tl1=,us'Wi-ll-` be subjected to the Scrapers. The portion of the leaves whichprojects-from between the chainDandwheelrF may be supportedbyV a carrier consisting of' belts,` orl sprockeuchains h, passing, around pulleysh, affixed tothe. shafts. d d2.- carried bythe chain and wheel. to a point Where they will be released they are; taken byhand and,.after beingreversed endfor end,

Asfthe leaves are are placed upon the support consisting of the shafts G-G, pulleys g, and sprocket-chains. Thereafter they will be passed between the table and scrapers again so that such portions as were left untreated before will nouT be treated. It will be seen that the chain D sinks down between the wheels or rollers D D2, so as to conform to the curve of the wheel F. This is important, and, indeed, the seV eral links of the chain will preferably be turned in a lathe, so that they may conform to the curve of the Wheel more accurately. An important feature vconsists in so combining the chain and Wheel that the flan ge of the chain which enters the groove of the Wheel will not touch the bottoni of such groove, and also so that the flange of the wheel that enters the groove of the chain will not reach the bottom of this groove. This feature enables the wheel and chain to grip the leaves with a Wedging action.

The chain D and wheel F obviously constitute traveling grooved intermeshing grippers.

That I claim as my invention, and desire to secure'by Letters Patent, is-

1. In a machine for preparing leaves' or fibers, the combination of a rotary support provided with Scrapers, a table adjacent thereto,'pulleys journaled in bearin' gs at the sides of the machine, a chain supported upon said pulleys, a wheel forcibly depressing the chain and extending between the' pulleys and a resilient support for said Wheel, the wheel and chain having engaging parts and forming traveling grippers to carry the leaves over the table and under the Scrapers, substantially as specified'.

2. In a machine for preparing leaves or fibers, the combination of the rotary support B, the Scrapers B secured thereto, thetable C arranged adjacent to the support B, the

ychai-n D', they pulleys D',- D2', D? over which i said chain runsy andV the wheel F, forcibly depressing. the chain, one of the'rotary members in contact with the chain' having a resilient support, substantially as specified.

In testimony whereof I have signedf my nameto` this specification -in the presence of two I subscribing witnesses.
