COTTON-PRESS.
SPECIFICATION forming* part f Letters Patent N0. 91,378, dated May 30, 1905.
Application iiled October '7, 1903. Serial No. 176,104. l
To @ZZ whom t may' concern:
Be it known that I, LoUIs K. STEPHENS, a citizen of the United States, residing at Dallas, in the county of Dallas 'and State of Texas, have invented new and useful Improvements in Cotton-Presses, of which the following is a specification.
My invention relates to a cotton-tamper to be used in connection with a cotton-press for preparing and baling lint-cotton for market.
The objectof my invention is to provide a l machine that will give to the presser or packer a positive up-and-down motion and that will prevent sticking or hanging of the same in the box. y
A further object of my invention is to provide an automatic reverse and stop motion for said packer.
The novelty of my invention consists in the combination and subcombination of the parts of my machine, as will be hereinafter set forth, and specifically pointed out in the claims.
The practical embodiment of my invention is shown by reference to the accompanying drawings, in which- 4 Figure 1 shows a side elevation of the machine complete. Fig. 2 represents a plan view taken on line 2 2, Fig. 1. Fig. 3 shows a transverse sectional view taken upon line 3 3, Fig. 2. Fig. 4 represents a cross-section take upon line 4 4, Fig. 2.
Like characters indicate corresponding parts in the several gures.
Referring to the drawings, 6 represents a base-frame which is preferably constructed of sills 6', that are arranged parallel to each other and which are united centrally by the cross-piece 7 and at one end bythe reciprocating frame-supporting brackets 8 and 9, mounted as shown. These brackets are provided with vertical guide-openings 10 and 11, that are alined with each other and that are adapted to receive the tubular uprights or draft- bars 12 and 13, which are intended for vertical reciprocation therein and which are united at their upper ends by the cross-beam 14 and at their lower ends by the packer or presser plate 14 and that are rigidly secured thereto by the centrally-extending bolt-rods 15, thereby constituting a vertically-reciprocating frame. The frame thus constructed and disposed is counterbalanced by a weight 16, that is suspended from the end of the rope 17, which latter is carried over the small pulleys 18 and 19 and ywhich is attached by its other end to the cross-beam 14. The means for vertically reciprocating said frame and attached presser or described. v
20 designates ahorizontally-disposed driven shaft that is journaled at one end in the brackets 8 and 9, above referred to, and at its opposite end portion in the brackets 21 and 22, which latter are rigidly secured in spaced parallelism to the sills 6. The shaft thus arranged is driven by power means to hereinafter be described.
The power from the shaft 20 is applied to reciprocate the packer or presser plate through the following means: Mounted on the enlarged portion ofthe shaft that extends between the brackets 8 and 9, and that is sustained in bearings thereon, is a windingdrum 23, that is of a given diameter throughout its length and that is provided between its peripheral center and one end with righthanded screw-threads or grooves and on its opposite end portion with left-handed screwthreads or grooves of the same pitch. The drum thus sectionally divided on its periphery has coiled or looped on its respective left and right handed grooves the separated strands 24 and 25 of the power-cable 26, that extends in a loop from the eye-plate 27, located centrally on the upper face of 'the presser-plate 14 and which when coiled on said drum form each one complete turn thereon to obtain a complete arc of contact and which extends from said drum in separated strands .28 and 29 to the head or cross-beam 14, where they are secured, respectively, to the adjusting eyebolts 30 and 31, positioned as shown. In this manner there is provided a transmission cable means that is coiled about the drum in the grooves 32 in a manner to prevent lateral displacement and to obtain thereon, by reason of the complete arc of contacts of the respective strands arranged thereon atasuitable angle, the best gripping action. By such an arrangement when the power packer plate will now be IOO is applied to rotate the drum in one direction the latter will cause the descent of the reciprocating frame and packer by reason of paying out and lengthening of the strands 28 and 29 and correspondingly shortening of the strands 24 and 25, and vice versa in hoisting the packer by the opposite rotation of the winding-drum. A similar arrangement with chains instead of ropes may be employed to obtain the reciprocatory movement.
33 and 34 designate metal friction bevelgears which are mounted, as shown, on driven shaft 20 in separation between brackets 21 and 22 and which are provided with corresponding but oppositely-arranged or opposed peripheral faces.
35 indicates a counter driving-shaft that is journaled at right angles to the driven shaft 2() on its inner end in the bracket 36, which latter is pivotally mounted on the sill 6', as shown at a. Mounted on the extreme end of said counter-shaft is a paper or wooden gear or cone 37, which is normally positioned midway between the gears 33 and 34, but which is adapted to alternately engage frictionally therewith to drive the shaft 20 in opposite directions. By the employment of such gearing the starting of the machine and the reversing of same are attained with as little shock as with belting and are fully as positive. The counter-shaft thus mounted and arranged may be connected with any suitable power.
The means present in this machine for controlling the alternate engagement and disengagement of the cone 37 with the gears 33 and 34 and retaining same in a given position will now be described. I* 38 indicates a shifting-lever that is pivotally connected at one end to the bracket 36 and at its opposite end portion to the sill 6 to provide at its latter end a trip portion 39. The trip 39 thus disposed is ranged in the pathway of the gib 40, that is carried on the `upper inner end of the packer-plate 14.
vShifting-lever 38 is also provided with a retaining or locking arm 4l, that projects at right angles at a point intermediate of its ends in a manner to extend crosswise of the machine and which is pivoted at 42, as shown. The arm 4l is provided with a hinged joint 43 at a point between its fulcrum and free end, which joint allows said lever to drop into a plane coincident with that of the notch 44, formed in the cross-piece 7, with which it is adapted to socket when it registers therewith. Arranged in opposition to said shifting-lever 38 is the tension-spring 45,that connects with one end to the arm extension 46,that projects from the bracket 36, and that is connected at its opposite end to a rod 47 by an adjustingturnbuckle 48.
The following means is provided for releasing the shifting lever when it is locked in the notch 44 against the tension of the spring 45. 49 designates a lever that is pivoted on the sill 6, as shown, to provide a free end {30,that is ranged in the pathway of the gib 51, which latter is mounted on the inner end ofthe crossbeam or head 14 at the top of the reciprocating frame. Pivoted at the opposite end of said lever 49 is a bell-crank-shaped disengaging or tripping lever 52, which is fnlcrumcd, as shown, to swing its free end through the recess 53, extending through the cross-piece` 7, which lever when swung therein is adapted to raise the arm 4l out of the notch 44 when seated therein, and thereby allow of the shiftingof the friction-cone by reason of the spring force exerted thereon.
IVith the parts constructed as shown and described the operation thereof is obvious. In Fig. l the shifting-lever is shown as thrown to a locked position to cause the engagement of the cone with the bevel-gear 34 to drive the shaft and winding-drum in a direction to cause the descent of the presser-plate, which when it reaches its downward limit of movement causes the engagement of the gib 5i with the free end 50 of the lever 49, thereby releasing the shifting-lever 38, through the swinging of the tripping-lever 52, to dislodge the arm 41 from its notch 44, as hereinbelore described, whereupon the spring 45 exerts its tension to pull the cone in contact with the friction-bevel 33 and cause the presser-plate and its frame to ascend by virtue of the reversal of the movement of the winding-drum. Upon the presser-frame reaching the upward limit of its movement the gib 40, located on the presser end of the frame, will come in contact with the free end of the shifting-lever, operating thereon to produce a pulling action on the cone and move it against the action of the spring to a neutral position between the bevelgears, thus bringing the presser-frame to a stop, where it is maintained by reason of the counterbalanciiig-weight. The operation may be repeated by again bringing the shiftinglever to its locked position.
