GERARD BEEKMAN, OF NEW YORK, N. Y.

TRANSMITTER FOR FIBROUS MATERIAL.

SPECIFICATION forming part of Letters Patent No. 482,155, dated September 6, 1892.

Application filed April 22, 1891- Serial No. 389,933. (No model.)

To all whom it may concern:

Be it known that I, GERARD BEEKMAN, a citizen of the United States, residing in the city and county of New York, and State of New York, have invented certain new and useful Improvements in Transmitters for Fibrous Material, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to machines in which it is necessary to convey fibrous materialsuch as cotton, wool, and other light substancesfrom one place to another, and it is especially applicable to cotton-harvesters, in which the cotton is picked near the ground .and must be continuously delivered to a basket or similar receptacle; and the objects of my invention are, first, to provide a transmitter by means of which the fibrous material may be readily conveyed in an inclosed space, so that no fine particles can escape to clog adjoining machinery; second, to transmit the cotton without injury to its fiber and Without the possibility of contact with oily machinery, and, third, to provide a form of transmitter which shall require a small amount of power to drive it. I attain these objects by the machinery illustrated in the accompanying drawings, in which similar figures refer to similar parts throughout the several views.

Figure 1 is a general side elevation of one suitable form of machine with which the improved transmitter is incorporated. Fig. 2 is a plan view of Fig. 1. Fig. 3 is an enlarged vertical section taken on the line a: m, Fig. 4, showing in detail the construction of the transmitter for transmitting the cotton from the cleaning-brushes to the receiving-baskets of the machine; and Fig. 4 is a vertical section on the line y y of Fig. 3. Fig. 5 is a horizontal section of Figs. 3 and 4, taken on the line 2 2', also showing diagrammatically the relation of the pickers to the cleaning-brushes; and Fig. 6 is asimilar horizontal section showing a modification.

Other features than those claimed herein in the cotton-harvester herein illustrated are more fully described and claimed in my separate patent applications, Serial Nos. 389,931 and 389,932, filed simultaneously herewith.

Referring now to Figs. 1 and 2, which illustrate a hand-machine, 1 is the main supporting frame; 2, the traction wheel; 3, the sprocket-driving wheel, attach ed to the wheel 2; 4, the sprocket-driven wheel, the shaft 5 of which is journaled in bearings 6 6 upon the rear part of the frame 1, and to which wheel 4 motion is imparted from the Wheel 3 by means of a band '7, having perforations into which the pins 8 of the respective wheels enter.

9 9 are the transmitting-shafts for driving the two groups of 'picking mechanism 10 10, one upon each side of the machine. These shafts 9 are driven from the shaft 5 by means of bevel-gearing consisting in a double-faced gear 11 and the gears 12 12 upon the respective shafts. The shafts 9 have bearings 13 14 in the lower and upper portions, respectively, of the frame 1, and the upper extremity of said shafts bear bevel-gears 15, engaging with the bevel-gears 16 of the circular racks 17, that propel the two groups of picking mechanism.

Referring to all of the figures, 18 18 represent the rotary cleaning-brushes, which remove the cotton from the pickers, and 19 19 the spirally-reciprocating actuators of the transmitter.

20 is the case or channel through which the cotton is transmitted by the actuators 19 into the basket 21, placed over the wheel and resting upon the upper rods 22 of the frame 1. The brushes 18 are driven in continuous rotation in the direction indicated by arrows by means of flexible shafts 23, guided by bearings 24 25 and connected with the rotary shafts 9 9. The actuators. 19, as shown in Figs. 3, 4, and 5, consist of rollers having barbs projecting in the direction of transmission, (in this case upward) and these barbs have'contact with or are very near the brushes 18 to catch the cotton.

A spiral reciprocating motion (indicated by arrows) is imparted by means of twisted flexible bands 26 27, of metal or other suitable ma terial, connected at either end to the extremities of the actuators and extended taut over the driving-sheave 28 beneath and the idle sheave 29 above. Theinterior of the caseinclosing the actuators is provided with barbs 110, projecting in the same direct-ion as those on the actuators, which hold the portions of cotton that are moved or lifted by the actuators 19. efiected by successive steps of ascending motion corresponding with each upward stroke of the the respective actuators 19. The driving-sheave 28 bears sprocket-teeth, which enter perforations in the lowerbands 26, insur ing positive motion. The driving-sheave common to both actuators 19 bears a spur-gear 30, driven by a spur-gear 3l,which has an oscillatory motion, rotatin gin one direction and then the other, so as to impart the necessary reciprocating movement to the. actuators. The oscillatory motion of the spur-gear 31 is imparted by a crank 32 upon a shaft at the rear end of the machine through the means of a block 33 upon the crank-pin,

said block being spirally threaded to the shaft 34 of said oscillating gear. The bearing 35 of the shaft 34 is swiveled to permit vertical vibratory motion of said shaft due to the motion of the crank, and while the shaft 34 does not have endwise motion its alternate rotary motion is necessarily imparted by the reciprocation of the crank-block 33 upon the spiral groove or thread thereon.

The described motions of the transmitting mechanism m ay beimparted by an yother suitable construction of devices than those herein described, the same merely illustrating one feasible form.

I have found that two actuators, in combination with the barbs upon the interior of the case of the transmitters, produce the best results, as they clean each other; but one or more would answer. I have found, too, that the spiral reciprocating motion imparted to the actuators produces the best results; but a simple reciprocating motion would answer to transmit the cotton.

In orderto prevent the barbs on the actuators and the interior of the case from injuring the cotton fiber or seed, I make either those on the actuators or those on the interior of the case elastic, or they both may be made elastic.

The machine thus generally organized is propelled by the handle-bar 40 and balanced by the operator upon the main'traction-wheel 2 between the rows of cotton-plants, while the groups of picking mechanism 10 operate upon the adjacent sideof each row of plants between which the machine passes. The pickers 76 consist of flexible stems having suitable mechanisms within the cases for spinning them upon their own axes, and said stems are partly exposed and partly shielded in flexible supports of coiled wire or other suitable material projecting from the picker-cases 70, as shown in Fig. 5. The pickers operated pass the brushes on the inner sides of their orbits in the direction indicated by the arrows h h in Fig. 5, and the tufts of cotton on the ends of the rotary pickers 76 are caught by the brushes 18 18, which rotate toward the interior of the case 20 and separate the cotton, delivering the same to the barbed actuators 19 The elevation of the cottonis thus.

which deliver the cotton, as hereinbefo're de scribed. 1 1

In order to prevent the possible exit of the cotton at the points 4; 2', Fig. 5,before it reaches the top of the transmitter, a modification may be provided, as indicated in Fig. 6. This consists in turning the flanges 111 of the case 20 inward toward the actuators in close proximity thereto. In this modification the barbs do not cover the entire surface of the actuators, but are limited to that indicated by the full lines shown in said Fig. 6, so that the barbs do not conflict with the flanges 111. The dotted lines indicate the spiral oscillation of the actuators. The motion of the actuators in Fig. 6 is otherwise the same as that hereinbefore described with reference to the other figures.

As indicated by arrows, a retrogressive direction of rotation is imparted to the pickerwheels 17 on the side thereof opposite the rows of plants, this driven rotation being rapid. Orbital rotation is imparted tothe depending leg 45, bearing the pickers,and rapid rotation to the pickers 76 themselves through mechanism fully described'in a separate patent applicationfiled simultaneously herewith, Serial No. 389,932,hereinbefore referred to, and the particular cotton-harvesting machine with'which the above-described improved transmitter is illustrated as incorporated forms the subject-matter of another separate application filed simultaneously herewith.

What I claim, and desire to secure byLetters Patent, is

1.
