Application filed August 13,1901. Serial No. 71,896,

Be it known that I, HARRY L. DUNCAN, a resident of New York, county of Kings, and State of New York, have invented a new and useful Improvement in Daling-Presses, of which the following is a speciiication, taken in connection with the accompanying drawings, in which the same reference character rei'ers to similar parts in the several iigures.

This invention relates to baling-presses for producing continuously a cylindrical bale of fibrous material, preferably composed of suhelical layers; andit relates more specifically to baling-presses in which the continuous bale is separated in the balingchamber into separate bales, and these bales are held against rexpansion and in proper compressed condition as they are continuously fed from the baling-chamber.

1n the accompanying drawings, Figure 1 shows in axial section one form of such a baling-press. Figs. 2, 3, and i are partial transverse sectional views taken on the lines 2 2, 3 3, and 4 4'of Fig. 1. lig. 5 is a perspective view of a retainer. Fig. is a partial transverse sectional view taken substantially through the ejectors. Fig. 7 shows in transverse section a modified form of bale-governing device as applied to the baling-chamber, talien on line 7 7 of Fig. S. big. 8 is a substantially axial section of the same, taken on line 8 8 of big. 7. Fig. 9 is an enlarged detail showing the bat forming and feeding mechanism, taken on the line 9 9 of l`rig. 10. Fig. 10 is another view of the same in elevation, taken from the right of Fig. 9. Fig. 11 is an axial section through a modified form of baling-press. Fig. 12 is a partial transverse section taken on line 12 12 of Fig. 11. Fig. 13 is a detail in substantial axial section, showing the construction of a modified form of ejector.

This press is composed of a relatively rotating baling-chamber B and slotted capplate A, the baling-chamber being provided with suitable retainer-slots B2, extending longitudinally of the same, through which balesevering retainers D are from time to time introduced into the continuous forming-bale within the chamber and serve to divide it into separate bales. The baling-chamber is also provided with suitable ejecting or baleregulating means, by which the movement of the continuous bale through the balingchamber is regulated. T he cap-plate is provided with suitable condensing-cones I and feeding-cones G, serving to form bats of material and feed them into the slotted cap-plate. T he baling-chamber B is substantially cylindrical, as shown in Fig. 1, and is formed with a slightly-tapering upper portion. This balingchamber is preferably stationary in this form of press, although it may be rotated, if desired. The cap-plate A is revolubly mounted with respect to the baling-chamber, the Bange B on the baling-chamber being clamped againstthe cap -plate by the collar A2, secured to the cap-plate by bolts, as shown. The cap-plate is revolved by the gear A, which is driven by any suitable mechanism at any desired rate of speed. ln the cap plate are mounted the two feedingcones G, rigidly secured to the stub-shafts GL at their outer ends and rotated by means of the beveled pinions G3, secured to them. These pinions mesh with the driving-gear B8, formed at the upper end of the baling-chamber, so that relative movement between the baling-chamber and the cap-plate serves to rotate these feeding-cones at substantially the same surface speed as the forming-bale with which they come in contact. rhe shafts G4 are supported in heavy bearings in the cap-plate A8, and the inner end of the feeding-cones are preferably formed with liournals G5, which have suitable bearing in the feederbearing A9 at the center of the cap-plate, although this center bearing may be omitted, if desired. it is understood, of course, that the feeder-journals G5 are slightlyout of line at the center of the cap-plate, so that the two feed-openings which extend 'substantially along the diameter of the cap-plate substantially coincide at the center of the same. The supplemental bearing-yoke A4, rigidly secured to the cap-plate, as is indicated in Fig. 9, serves to support the feeder-cone, since it comes in contact with the bearing portion G2, which may be located near the center of the comb, as indicated in Fig. 1, so as to support this comb at the center and resist the upward pressure upon it. feeder-cones G are formed with suitable corrugations G', by which they more readily engage the material and feed it into the feedslot A3 ofthe cap-plate.

lt will be noted by reference to Fig. 9 that the inner surface of the cap-plate is formed with a relieved portion A6 on its under surface adjacent each feed-cone, so that the material compressed against the upper end of the forming-bale under the cap-plate is re- As is indicated, the

IOS

leased from close contact at this point, and the material is thereby disengaged from the feeding-cone. The edge of the cap-plate A5 at this point closely engages the feeding-cone and serves to assist in freeing the material from the feed-cone.

Instead of forming the cap-plate with a substantially ilat inner surface, as is indicated, this cap-plate may be formed with a conical inner surface, as is indicated in my Patent No. 671,918, April 9, 1901, the condensercones and the feeding-cones being so placed that their apices still substantially coincide with the axis of the press. The two condensing-cones I are mounted by means of suitable journals I', which have bearing in the central portion A9 of the cap-plate, and by the bearing-collar H, which engages a suitable bearing I2 in the bearing member H. This condenser-cone is formed of perforated or foraminous material, as is usual in this art, and is driven by the beveled gear I3, secured to the collar H, which is driven by the idler G, rigidly secured to the stub-shaft G7, mounted in suitable bearing in the bearing member H. This idler is driven in turn by the feeder-gear G3, so that, as indicated in Fig. 9, the condenser-cone and the adjacent feeding-cone revolve in the same direction and at substantially the same surface speed, although in practice I refer to operate the feeding-cone at a slight y-greater speed than the corresponding portion of the condenser cone. Within the condenser is located the shield I5, supported on a central rod I4, bolted to the outer bearing member H, which is rigidly secured to the bearing member Hin any desired way. Each condenser cone is provided with a series of slides I7, asis indicated in Fig. 9, these slides being mounted to move slightly about the axis of the condenser-cone and being adjustable in any desired position by the bolt and nut I8, secured to the slide and operating in a slot in the casing H2. The cover-plate I9 lits over this slot and is engaged by the nut, as is indicated. To the upper end of each one of these slides is permanently secured the single flexible curtain or cover strip I, which is fastened at its upper end to the side of the casing H2. In this way as the slides I7 at various parts of the condenser-cone are moved about the axis of the cone the cover-strip serves to shield a greater or less portion of the condensercone at that point from the lint or blast of material which is continuously fed to the condenser-cone. In this way the active angle of the condenser-cone may be adjusted at various points along the cone to form a bat of any desired cross -section It will of course be understood that any desired number of slides may be employed, so that any desired nicety of adjustment may be obtained in this way. The action of this adjustable bat-former is similar to that set forth in my Patent No. 672,394, April 1c, 1901.

-ner or feeding chamber is connected with the cylindrical feed-pipe, (not shown,) which serves to supply a blast of material-such as cotton, wool, or other fibrous material-to each of the condenser-cones, while the annular exhaust-space H3, which communicates with the interior of the condensercones through the bearing-collars H9 of the same, serves to create a suction within the cones, as will be readily understood. The outer casing H is of course connected with an outer pipe, (not shown,) the annular space between these two pipes being connected with a suitable exhaust-fan to maintain the desired suction within the exhaustspace H3. The cap-plate Ais formed adjacent the feed-opening with a feed-plate A7, and the adjacent part of the casing is formed with a hinged member H5, hinged to the casing at the point'H7 and pressed. inward toward the condenser-cone by the spring HS, so that this hinged member, which is provided with a friction-roll H6 along its lower edge, presses against the bat of material formed on the condenser-cone I. The bat'becomes disengaged from the cone at the lower portion of the same where the shield I5 cuts olf the suction, so that the bat is continuously fed down the feed-plate A7 and into the feedopening A3 under the feed-cone. In this manner a bat of material of uniform thickness at all points is continuously supplied to each of the feeding-openings A3, which extend from the axis ofthe press to the sizingcollar B7 at the top of the heling-chamber; also, since the apices of the condensingcones substantially coincide with the axis of the baling-chamber, the length of the bat ofV material supplied from these cones to va- IOC lio

rious parts of the feeding-slot are proportionate to the distance from the center of the baling-chamber, and therefore the bat is correctly distributed throughout all parts of the resulting bale.

As is well known in this art, the rotating cap-plate A, operating in connection with the baling-chamber B, serves to produce within the baling-chamber a continuous formingbale composed of superposed helical ribbons of material. This continuous bale is governed in its movement longitudinally of the baling-chamber by the v ejector-wheels E, whose construction and operation are substantially similar to those shown in my Patent No. 671,918, April 9, 1901, As is best shown in Fig. 6, the ejector-shafts E8 are mounted in suitable bearings Ewon the lower part of the baling-chamber, and the two IIS ISO

ejector-wheels E, formed with the bale-gripping spikes e, project through suitable ejectorslots E2 into the baling-chamber. Splined to the outer end of each of these ejectorshafts is the skew-gear E, the teeth E2 of which mesh with the skew-teeth E3 upon the crown-gear E4. This crown-gear is mounted upon the lower end ol' the baling-chamber by a suitable collar E, is rotated at any desired speed relative to the baling-chamber by the gear E5 upon its edge. In this way, as will be evident, each one of the ejector-wheels is rotated at the same peripheral speed and engages the continuous bale within the chamber and positively feeds it through the chamber at any desired rate. In this way the density of the resulting` bale may be varied, as will be manifest.

The retainer-slots B2 extend longitudinally of the baling-chamber between the two ejector-wheels, mounted upon a tor-shaft. Each of these retainer-slots is provided with the shoulder B3, so that the lower end of this slot is wider than the portion of the same above this point. The retainer-slots, as is shown, extend to a point near the upper end of the baling-chamber, as is shown in Fig-1, to the upper end of the cylindrical portion of the baling-chamber. The upper portion of the retainer-slots are open for the convenient insertion of the retainers into the bale wi thin the chamber, and the bridge-pieces B4, extending around this part oit'` the retainer-slots, serve to strengthen the upper portion of the baling-chamber. The retainer-guides C3 are formed adjacent the retainer-slots and serve to maintain the retainers in proper position with respect to the bale. The upper retainer-guide C3 is formed with a cam portion C, and the lower retainer-guide at the other side of the retainer-slot is formed with a cam portion C5. These cam-guides serve to force the retainer inward.

The retainer shown in perspective in Fig. 5 is formed with a body portion D, connecting the two feet D D2, having the sharpened points D3 and D4, respectively. Upon the heels of the retainer-feet are formed the cam portions D5, D, and D7 upon the upper l'oot and the cam portions D8, D2, and D0 upon the lower foot D2, as is shown in that figure. The upper retainer-cam C, formed on the member C, projecting from the side of the bridge-piece B4, has, as is shown in Fig. 2, only a single gripping-groove, which engages the retainer-cam D5 and holds it in proper position in the groove, the point D3 of the retainer having been inserted in the retainerslot B2, and the foot D2 being positively guided into the bale by the edges of the slot and by the retainer-cam C', as is shown in Eig. 2.

The upper retainer-guide, formed on the bolted to the same, and4 be readily seen single ejec-` member C2, is provided below the point C4 in Eig. l with a second gripping-groove C3, which engages the cam DG upon the upper retainer-foot D31, as shown in Fig. 3, a section at this point, and the retainer-guide at this point also comes in contact with the cam D7 on the retainer-foot, so that the retainer is held inward at this point throughout the whole rearward extent of the foot. It will that since the retainers are placed in the oblique position indicated at F ig. 1, the upper foot of the retainer being at one side of the retainer-slot and the lower toot being at the other side of the slot to engage the lower retainer-guide, the upper retainercam must be cut away above the point C4, since otherwise the body of the retainer near the upper foot of the same would come in contact with the gripping-ledge and the coaction of the retainer-cams with the cam-guides would not be correct.

The lower retainer cam guides C5 are formed on the interior of the relieved portion B5 of the lower end of the chamber, as is shown in Eig. l, and, as is indicated in Fig. 4, this cam-guide is formed with two grippinggrooves, which engage the cam portions o' the lower foot of the retainer throughout its whole rearward extent to positively force this foot into the continuous bale. Both the upper and lower retainer-guides below the cam-guides are parallel to the axis of the press, so that the retainer once having been forced into the bale is held positively in that position by the retainer-guides as it moves, together with the bale, through the balingchamber. The operation of these retainers in separating and holding separate bales in proper position is as follows: The balingchamber being iilled with a. continuous bale, which is lied through the chamber at a definite rate by the ejectors, a set of retainers are successively inserted through the spaces BG within the bridge-pieces B4, so that the upper feet of these retainers pass through the retainer-slots B2 and are forced to a slight extent into the bale by any suitable means, so that they retain their position longitudinally of the bale. are placed at the other side of the retainerslots in position to properly engage the camguides (J5. Then the lower points of the retainers are also forced to some slight extent into the bale to travel with the same. Then this set of retainers, which of course are forced into the bale symmetrically, as indicated in Fig. l, engage the cam-guides, which The lower feet of these retainers IZO force the upper and lower points of the retainers readily into the forming-bale, and when the retainers have been forced into the bale to the extent shown in Fig. l thereafter they travel with the bale through the balingchamber. Vhen the upperieet of this'set of retainers comes into the open portion of the retainer-slots below the bridge-pieces B4,

ISO

another set of similar retainers are inserted' in like manner into the forming-bale, the

lower points of this second set of retainers being inserted into the bale directly alongside of the upper feet of the first set of retainers. This second set of retainers is engaged by the cam-guides, forced into the bale, and fed forward with the bale in a simin lar manner. This operation is repeated, and it will be seen that a series of separate bales are ejected from the baling-chamber and that each bale will be heldin proper compressed position by the set of retainers extending from end to end ofthe same. These retainers on each bale may of course be held temporarily in position as the bale issues from the lower end of the baling-chamber by straps or by any suitable means. As the separated bales issue from the press they may be readily separated from the continuous bale within the baling-chamber by any desired means, and it will'be notedin this con nection that the feet of the retainers entering the continuous bale serve to separate it into separate bales. Permanent binding means are now applied to each bale ina well-known manner, or, if desired, the retainers may be rigidly secured in position and constitute the permanent binding means.

Although I preferably form the chamber containing the retainer slots and guides integral with thel chamber which coacts with the cap-plate to form the bale and also form the ejectors or other bale-governing devices on this chamber, it is not necessary that these members be formed as a single piece. The retainer-guides should, however, be formed on a slotted bale-supporting chamber through which the bale is fed.

It will of course be understood that it is not necessary to form the retainers exactly as I have disclosed. The number of cams upon the feet of these retainers might be varied, and the shape of' these cams might be varied from what I have disclosed in the drawings. Readily-releasable retainers might be used in this form of' press. Furthermore, it is not necessary in all cases that camguides be formed adjacent ythe retainer-slots to automatically force these retainers into the bale as they travel with the bale through the baling-chamber. Other means of forcing these retainers into the bale might be employed. The exact shape of the retainers and of the retainerslots and the number o1c these retainers and retainer-slots might be varied, although the points of the retainers should project sui'liciently far into the forming-bale to hold the bale in position and prevent rexpansion of the same after the bale issues from the press, and the feet of the retainers should be made suHiciently long to accomplish thisresult.

Instead of the form of ejectors which I have just described any other means of regusuitable relieved portions may be lating the movement of the forming-bale through the baling-chamber may be employed, and in Figs. 7 and 8 I show a series of bale-governing elements F F, pivotally secured to the lower end of the baling-chamber Bo by the heavy pivots F The clamping-ring F 3, secured to the lower end of the baling-chamber by bolts, is provided with the clamping-screws F 4, which serve to adjust the pivoted members F in any desired position, the lock-nuts 'shown holding the clamping-screws in place. As is indicated, the lower end of the baling-chamber is formed with a slight taper F2, so that the movement of the bale from the baling-chamber is resisted by this tapered portion. The baleegoverning elements F serve to increase the frictional grip of the lower end of the baling-chamber upon the bale, and infthis way a greater or less resistance is oered to the longitudinal movement of the bale. The speed of movement of the bale, and therefore the density of the bale, are regulated in this manner. As is shown in Fig. '7, the retainerguides C73 and C75 areformed between the bale-governing members, and the retainerfeet D71 Dm'shown in this figure are formed with cam portions and operate in connection with the retainer-guides, as has been already set forth.

In the modiiied-form of baling-press which I have disclosed in Figs. 11 to 13 the balingchamber B10 is formed with the retainerslots B2, as has already been described, and also with the longitudinal slots B12, as indicated, These slots are formed at their lower portions with an inward taper, so that the continuous bale passes without interference past the lower end of these slots. It desired, formed in the lower part of the balingechamb er as a continuation of these slots, so that in this manner the continuous bale engages the balingchamber throughout only a portion of its circumference. The heavy sleeves M pass about the bridge-pieces and serve to hold the baling-chamber together and to resist the internal pressure of the bale upon it. In this way the baling-chamber below the sizingcollar at its upper end, which as is shown in this ligure, is formed cylindrical and without any taper, may, if desired, be formed to engager the continuous bale only throughout the ribs B11, in which the retainer-slots and retainenguides are formed, as has already been described. The retainers in this case operate in an exactly similar manner to what has been `already disclosed', and the cap-plate and the parts carried thereby alsooperate in a similar way. I have shown in this case a different form of ejector, consisting of a series of screw ejectors K', having a conical bodv and being formed with a multiple helicalv ridge or screw-thread K of varying height throughout the body of the ejector. The

lO.l

IIC

axes of these screw ejectors are inclined slightly to the axisof the press, so that the ejector-threads engage the forming bale through the ejector-openings B14, inclined, as is indicated at B15, to a greater and greater extent as the bale moves forward. This gradual impingement of the ejectorthreads upon the forming bale is very beneficial, since in this manner less power is required to operate the ejectors. Each of these ej ectors is rigidly secured to an ej ector-shaft K2, mounted, as is indicated, in suitable bearings K5 at the lower end of the balingchamber B10. Bigidly secured to these shafts are the ejector-pinions K1, which mesh with and are driven by the teeth M4 of the large ejector-gear M, as is indicated. This gear is mounted in the bearing h in the lower end of the baling-chamber'and secured in position by the sectional clamping-collar M2, bolted to the chamber. This gear is rotated about the baling-chamber at any desired rate by the teeth M, with which a suitable driving-pinion engages.

In Fig. 13 I have shown a modified form of screw ejector, formed with a conical body K10 and with a helical ridge K12, of graduallyincreasing height throughout the ejector. This ejector is mounted, as indicated in the bearings M15 M1, which engage the ejectorshaft K12. The ej ector-pinion K13 is rigidly secured to this ej ector-shaft and meshes with the teeth M14L of the large ejector-gear M10, driven by means of the teeth M13 on its edge. This gear is mounted in a suitable bearing M11 on the lower end of the baling-chamber B10 and is clamped in position by the collar M12, bolted to the baling-chamber. It will of course be understood that this screw ejector projects through a suitable opening into the baling-chamber and'engages in a manner similar to the ejector K'the continuous bale within the chamber. The height of the ejector-threads or helical ridges formed on these screw ejectors must be sufficient so that the series of ejectors employed grips the forming bale within the chamber sufficiently to prevent any slip of the bale past them, and as the ejectors are rotated they serve to positively feed the forming bale through the baling-chamber at any desired rate. Since all the screw ejectors of a set operate in unison, each one tends to feed the bale forward at the same rate, as will be understood.

It will of course be understood by those familiar with this art that numerous modifications may be made in the baling-presses which I have disclosed. Furthermore, it is possible to employ these bale-separating retainers in connection with a press adapted to produce continuously a bale of rectangular cross-section. The baling-chamber in this 4case would of course be provided with suitable longitudinal retainer-slots and retainergrooves. Suitable means would also be employed in this case to regulate the movement of the continuous bale through the press. Numerous other modifications might be made, and parts of my baling-press may be employed apart from the others. I do not, therefore, wish to be limited to the disclosure which I have made in this case but what I desire to secure by Letters Patent is set forth in the appended claims.
