APPARATUS FOR COMPRESSING COTTON OR OTHER FIBROUS MATERIIALS.

SPECIFICATION forming part of Letters Patent No. 645,728, dated MarchQO, 1960. Application filed myzv, 1899- $erialNa72512'79. (NomOdelJ lowing is a specification.

This invention relates to an apparatus for compressing cotton, hay, wool, and other fibrous materials, and has for its object the provision of mechanism to sever the portion of compressed material to form a bale.

The invention consists in substantially the constructions and arrangements hereinafter described, and more particularly pointed out in the claims.

This application relates particularly to the mechanism for severing or separating a sufiicient length of the compressed material to form a bale.

It is manifest that the severing mechanisms herein described may be used in connection with various forms of compressing mechanisms, and I therefore do not Wish to be understood as limiting myself to any particular form of compressing mechanism in this connection, although the severing mechanisms described are particularly well adapted to be used with the class of machines in which the bale is built up endwise in spiral layers. In the drawings it is not attempted to show the full details of the compressing mechanism proper, but merely enough of such mechanism to illustrate the application of the. present invention thereto.

In Figs. 1, 2, 3, 4, 5, and 6 of the drawings there is illustrated a severing mechanism applied to a form of press in which a bale is formed in an open-ended chamber and is advanced through such chamber until it emerges from the lower end thereof for a sufficient length for a bale and then has that length of the compressed column severed.

In the drawings, A designates'the chamber in which the material is compressed and through which it is advanced by the addition of successive increments upon the top thereof. The dotted lines below this chamber represent a portion of the compressed column, sufficient to form a bale, and this bale is desig- 8o nated by the letter C. A support for the bale is designated by the letter D, and such support is preferably yieldingly held in position by a plunger of a hydraulic jack, such as is shown in other figures of the drawings.

The material -which is being compressed bears at its lower end against the support just referred to, and thereby meets sufficient resistance to aid in its compression, and also when its density is sufficient the support tends 0 to retain the same, or, in other words, to keep the column from endwise expansion at the lowest point thereof. I

. The severing mechanism is of course applied to the column of compressed material at 5 a distance above the lower end thereof sufficient to equal the length of bale desired, and this is true whether the portion of the column used for the bale is that portion which has emerged from the chamber in which it is .Too

" bale.

formed and extends below the same or whether it is the part of the column retained within the chamber.

In Figs. 1, 2, 3, 4, 5, and 6 of the drawings the severing mechanism is shown as applied to sever the column after it has emerged from the forming chamber or holder; but it is manifest that such severing mechanism may be applied, as shown in other figures of the drawings of this application, to separate the column at a point above the forming-chamber. In either case the point at which the severin g mechanism acts constitutes the top of the If the forming-chamber is open at its bottom and the column is made not only to pass into and through the same but emerge beyond the same to a sufficient distance to form a bale, then the severing mechanism should be applied just below the lower end of the holder or chamber, as shown in the first six figures of the drawings; but it the holder .or chamber is not constructed to permit the passage of the compressed material or column through the bottom of the same then as thelength of the column sufficient for the bale is, inclosed in the holder the severing mechanism must be applied above the holder, as illustrated in'other figures of the drawings, and provision must be made for taking the bale from the holder by removing a portion or all of the holder.

In the construction illustrated in the first six figures of the drawings the severing mechanism is duplexthat is to say, there are two blades which are to be inserted in the column of compressed material, the one for effecting the separation and also retaining the portion of the column remaining in the holder under compression and the other operating in conjunction with other parts, hereinafter to be described, to retain the bale which has been separated in its condensed form until it is wired. The construction and operation of this severing mechanism will now be specifieally described. The holder or chamber A may be provided with an extension A, which for convenience is bolted thereto, as shown. This extension has formed upon its inside a dovetail slot or other suitable guideway, which is clearly illustrated by the dotted lines in Figs. 2, 4:, and 5 of the drawings and by full lines in Fig. 6 of the drawings. In this guideway the correspondingly-shaped block E is intended to slide. This block E has secured to it in any suitable manner a cuttingblade a. This cutting-blade a is designed to be forced into the column of material and cause a separation between the length of the same for the bale and the material above such bale and also in the construction illustrated in Figs. 1 to 6 of the drawings to prevent endwise expansion of the material remaining in the compressing apparatus after the bale portion of the column has been removed. Another cutting-blade b is in the arrangement illustrated in the first six figures of the drawings secured to and serves as an operating part of astay F, which stay will be hereinafter more particularly described. The cuttingblade I) is guided in the guideway and, as shown in Fig. 6 of the drawings, is preferably arranged to move alongside of the block which carries the cutting-blade (t, with the difference that the side of the guideway which guides the cutting-blade Z) is near its inner end cut away, as shown in Figs. 2, 4t, and 5 of the drawings, and that a sprin g-actin g pivoted latch c is caused to snap behind this blade I) as soon as its butt-end has passed the inner end of the latch. The several positions of these two blades from the beginning to the end of their operation are shown in Figs. 2, a, and 5 of the drawings.

Fig. 4 of the drawings illustrates the two blades to and b in their initial position before they have been actuated. Fig. 5 illustrates the two blades after they have both been ac- V tuated and caused to enter the compressed column. Fig. 2 illustrates the cutting-blade a in its initial position and the cutting-blade I) being inserted in the guideway and not yet extension A of the holder before mentioned and provided at its other end with an inner and outer cam surface or projection. A pin f is arranged to pass through an elongated slot in this arm (Z and into the sliding block E, so that any movement imparted to this pivoted arm reciprocates the sliding block, and thus causes the blades to be forced into the material of the compressed column. The blade a is forced into the compressed column because it is connected directly to the sliding block, and the blade I) is made to also enter the compressed column, because the latch c, which is fastened to the sliding block at one end, bears against the rear end of this blade Z). A pair of vertically-reciproeatin g bars or rods 9 are arranged above the pivoted arm 0?, with the lower ends of each capable of being projected into the path of the cam-surface on the pivoted arm. Any suitable mechanism is provided for throwing these rods into position, so as to be in the pathof one or the other of the cam-surfaces on the pivoted arm. In the drawings the rods are formed with rack-teeth on their inner surfaces and are capable of being actuated by a pinion h. Pinions for operating the several sets of rods g may be connected by connecting-rods 2', as shown. It is manifest that as the chamber revolves it will carry with its extension the pivoted arms cl, and if at any point in this rotation a rod g is projected downward into the path of rotation of this arm it will engage the lower end of the rod so projected and will thus be forced to turn on its pivot and reciprocate the sliciing block E, and consequently operate the severing-blades. If the outer rod 9 is the one ICC projected into the path of the projected arm, such pivoted arm will be forced inward; but if the inner rod 9 is the one projected into the path of the pivoted arm the blade a will be carried outward, and thereby be taken out of the way, so as not to interfere with the next compressing operation. However, when the blade (1 is thus withdrawn the blade I) will not be affected, for the reason that when it was forced into the bale it passed inwardly beyond the flange on the guideway, and thus was left free to be removed with the bale.

The support D is provided with flanges or hooks, as shown, and the lower end of the stay F with engaging hooks, so that the bale after it is separated from the other material is held between the blades?) and the support D, as shown in Fig. 1 of thedrawings, the connecting-links F serving to join the blades 19 and the support D. In this manner and as above described the material which has been severed is kept under compression by the blades 1) and supports D, and the portion of the column remaining in the holder is kept under compression by the blades a remaining underneath the same-and holding the material up against the inside of'the cap-plate. This form of mechanism for severing the bale and retaining the compression in all the material which has before been compressed has been found very eflicient in practice and is especially applicable to that form of press in which the former or holder is revolved.

There will now be described more specifically the modified arrangement of severing mechanism and modified form of holder and support connected therewith, so as to virtually be a portion of such holder. The specific construction of this mechanism is shown in Fig. 10 and will not be claimed in this application; but such construction is herein described for the purpose of illustrating the genus of which it forms one species and which genus is claimed in this application. In the present form of construction the slotted capplate or head is rotated. The cap-plate is designated by the reference-letter B and is bolted or otherwise secured to a ring B which, in fact, is to be regarded as a part of the cap-plate and is used in addition for convenience in manufacture. This ring B has upon its under edge a circular rack B which engages with and is driven by a pinion B. It is to be understood,of course,that the pinion is driven from any suitable source of power. There are also several idle pinions B which are journaled in the frame and mesh with the rack, and thereby assist in supporting same. Between the ring of the cap-plate just referred to and the main frame B it is desirable to employ antifriction devices, such as the rollers 4. (Shown in the drawings.) The ring attachment of the cap-plate is provided with a series of vertical openings .9 therethrough, so as to permit insertion of a corresponding number of severing-blades and stays, which severing-blades and stays are designated by the reference-letter F. The point of eachsevering-blade is just back of or flush with the inside of the ring, and the heel of such blade extends outwardly into a recess or offset from the vertical opening 8, which olfset is designated in the drawings by the letter 8. The width of this offset is small, being sufficient to enable the blade to be supported by the horizontal wall thereof, and narrow enough to permit the heel of the blade to readily clear the vertical wall or shoulder of the offset when the blade is projected into the compressed material. The proximity of the severing-blade to the under side of the slotted cap or head may be adjusted by a suitable means, and a convenient device for the purpose is a circular ring held up by a setscrew. The circular ring is designated in the drawings by the letter t and the set-screw by the letter t. The purpose of making the severing-blades adjustable, in the manner just described, is to adjust the position at which the compressed material will be severed, so as to leave a comparatively-small amount of material in the press after the bale has been removed, or a larger quantity therein, if desired. The severingblades are also each provided with a pin Lt, projecting from the upper surface thereof and above the slot or opening through the ring and cap-plate. The severing-blades are connected intermediately with the bale base or support D by any suitable construction, which in the instance shown may be termed a bale-stay, whose lower hooked end connects with the hook or flange of the bale base or support. Of course it will be understood that the intermediate means connecting the bale base or support with the severing-blades is not necessarily formed in one piece with such blades, but may be in the form of a slat. It has been found convenient, however, to use the stays themselves as slats and connect such stays detachably with the bale base or support and permanently with the severing-blades, for by this construction it is obvious when the bale is removed it will be held against expansion by means of the bale-base and the severingblades, and after the bale is removed and wired these severing-blades and stays may be readily detached or knocked down, thus dispensing with the necessity of having the separate holder and a top ring or head for such holder and a hinged section through which to remove the bale, for in thisinstance the stays perform the office of a holder and are readily detached, so as to expose the bale and support the severing-blades. In this Way the blades are also carried by the holder. Of 1 course the width of these stays may be varied to suit the necessities of the material being baled, and the number of them likewise vary. In fiber with a short staple and much elasticity the stay should be rather wide, so asto not leave too much space between them, and comparatively numerous. In ordinary cotton about eight stays are found advisableto form the holder. In a long'staple inelastic mate rial, like dry hay, probably four would be found suificient. With this construction the holder then consists, practically, of three parts viz. the bale base or support, the stays, and the blades at the upper end of such stays, this last-mentioned feature being called a part because it has an additional office of severin g, as well as retaining the bale under compression.

It will be seen that the base-plate or support for the bale is loose and free to move vertically both with relation to the stays and with relationto the cap or head and severing-blades thereunder, so that such base-plate or balesupport is adapted to be projected upward by the plunger of the hydraulic ram to a point in proximity to the underside of the cap-plate, whereby, in connection with such plunger of the hydraulic ram, it will form a resisting means or counter-abutment against which the fibrous material has advanced during the compressing operation. On the otherhand, when the base-plate or bale-support has been depressed by the advancing column of compressed material until its flanged or hooked edge engages the hooked ends of the stays this downward movement will be temporarily arrested, because the heels of the blades are still in engagement with the shoulders of the offsets. The column of compressed material,however, at this time has a suflicient length to form a bale, and by the mechanism hereinafter to be described the pins projecting from the upper sides of the blades are projected inward and the blades caused to enter the column of compressed material and separate the same from the material being fed into the machine, and at the same time the heels of these blades clear the shoulders of the offsets in the ring and are in position to permit the bale and holder to be depressed, so as to clear the capplate and ring and be adapted to be moved laterally out of the way for wirin g. Of course the plunger of the hydraulic ram or other resisting plunger must be lowered a sufficient distance to allow this holder to be depressed, as just stated, so as to clear the cap-plate and ring. The holder comprising, as before stated, the base-plate, the bale-support,and the stays, the blades will then retain the severed bale in their grasp and prevent endwise expansion and may be swung out of the way in any suitable manner. A section of the swinging arm Gr, having upon it the track or way H, upon which the bale-support will rest, is also shown in Fig, 10 of the drawings.

To avoid all liability of the bale-stays coming oil before the bale is wired, abale-clasp V may be employed to encircle such stays.

The mechanism for projecting the severingblades into the compressed material in the construction now being described is the same in principle as that for projecting blades in the'form of construction first described, but diifers slightly in mechanical detail, and this difierence will now be specified.

Arms 02 are pivoted at one end to the upper part of the frame B and are provided with elongated slots, as shown, in which play pins of rocking arms 61 the outer ends of which rocking arms are pivoted to connecting-links d whereby all of the rocking arms are joined together and all caused to actuate the pivoted arms simultaneously. One of these rocking armshas an extension formed as a handle, by

which the attendant may move this arm and through the connection specified thus move all the arms and also the pivoted arms; When the arms are thus moved, they assume the position shown in dotted lines in Fig. 7 of the drawings, in which position the pins and rocking arms will be at the outerends of the slots in the pivoted arms and the pins and pivots thereby be placed in a straight line, which acts as a dead-center to prevent any change of position in an outward direction by reason of any part contacting with the inner side of the pivot-arms. When, however, the pivoted arms are thrown into this position, the pins which project upwardly from the severing-blades and are being rotated with the head or cap plate are caused to engage the inside surface of these pivoted arms, and inasmuch as such pivoted arms, as above explained, cannot move outwardly and the severing-blades may move inwardly the latter are caused by the inside surface of the pivoted arms to be projected into the compressed material far enough to cause the heels of such severing-blades to clear the shoulders of the openings 8, so that the bale will be thereby severed and at the same time provided with means for preventing endwise expansion when it is detached and taken from the machine, because such ,bale is grasped between the severing-blades and the bale base or support. The plunger of the hydraulic ram is then lowered so as to be below the arm G of the turning frame or turn-table, as it is usually called,and the bale supporuthe stays, and severing-blades and the detached bale inclosed thereby will then follow this plunger until the bale-support rests upon the track H, when it will be swung out of line with the compressing mechanism and an empty balesupport returned in its place and a new set of severing-blades and bale-ties dropped from above through the slots in the ring under the cap-plate, so as to form a new holder and be in position for receiving and forming another bale.

After the bale has been compressed it is to be wired, so as to retain such compression and be in condition for transportation.

In the present application these two plans are separately exemplified in several figures of the drawings, as has been before described; but it is obvious that instead of the bale-stays being multiplied to form a holder for the bale any other form of holder might be utilized in the same connection, provided the bale base or support is independently movable in relation thereto.
