Definitions
- This invention relates to machinery for producing cylindrical bales of fibrous material by means of a relatively-rotating slotted capplate and baling-chainber; and it has for its object novel means for producing suoli a bale of material so that it will be su bstantially co'- herent or self-binding and of substantially uniform density from center to circumference.
- Figure l is a sectional plan view of my improved press and feeder therefor, taken on line 1,'1 of Fig. 2.
- Fig. 2 is a transverse sectional view of the saine, taken on line 2 2 of Fig. l.
- Fig. 3 is a detail view, on a larger scale, taken on line 3 3 of Fig. 2, showing the construction of the feeding-chains for supplying the Inaterial to the capplate of this press and means for mounting the saine.
- Fig. et is a detail view, on a larger scale, showing a modified con struction of press, the View being taken transversely to the axis of the press near the point of the cap-plate.
- the cap-plate o is formed with an inner surface substantially a paraboloid, as is shown by the cross-section along the axis of the press.
- This cap-plate is held stationary by being secured to heavy framing ffs.
- the screw ejector c Just behind the cap-plate and having a bearing in the flanged extension ct' thereof is the screw ejector c, formed with an integral gear c3.
- the meshing gear a2 upon shaft a3, mounted in suitable bearingsf8 in the frame, may be rotated at any desired speed, so as to vary the speed at which the ejector is driven.
- the screw-thread c' of uniform pitch, but having the threads gradually increasing in height at the inner end.
- the baling-chamber b having a bearing-collar b' at the inner end.
- the annular flanges a7 as hold these two elements in position and are boltedto an extension of the frame ff.
- the gear b2 is secured to b, and just below it the frame f7 incloses the chamber b, so that it can revolve properly about its axis.
- the shaft b4, carrying gear b3, meshing with b2, can'be revolved at any desired rate by suitable means, and it serves to vary the speed of revolution of the chamber b as desired.
- Longitudinal ribs or fins b5 are formed on b and project into it, as shown.
- the press proper therefore consists of the substantially parabolic capplate Ct, which is stationary, the cylindrical screw ejector c, and the cylindrical balingchamber b, both of which revolve about their axes, which coincide with the axis of the capplate.
- Feeding mandarme-A condenser-cylinder e of foraminous or wire-net material, is rotated about its axis at any desired speed.
- Fixedly attached to the stationary shaft e' is the shield e2, which is supported adjacent the lower part of the condensencylinder. rlhese parts are supported in and surrounded by a casing e3, which supports the strip e5 of flexible material, such as rubber, adapted to press forward against the bat of material which collects on the cylinder.
- the flexible strip e4 is attached to the casing on the other side, and its lower edge is attached to the upper ends of a series of slides e6, mounted on the support e7 and adapted to be clamped in any position thereon by bolts and washers es, which work in connection with large openings in the support e7.
- the concentric pieces e6 can therefore be adjusted after removing the lower section of e3 adjacent thereto through a considerable angle about e and, as shown in the plan view, can vary the effective angle of the condenser c, which is active to collect material fed to it in a blast of airsupplied through an opening in the top of the casing e3.
- able doffer e9 operates in connection with the condenser-roll under the shield, as is usual in this art.
- the air is exhausted from the inside of the condenser by an exhaust-pipe ew, connected therewith in a usual manner and also connected with some suction device.
- the bat formed is carried by an apron g, mounted on roll g, driven positively bythe shaft g2, so as to give the apron the same surface speed as the condenser-cylinder, and also passing over roll g3, loose on shaft g4.
- the apron rests on the plate g5, which is supported on the framing j" and on the heavylip a5 of the capplate.
- feedchains d Adjacent to the feed-slot are the feedchains d, which have formed on their outer working faces slight projections or teeth, so as to grasp the bat of material and positively feed it forward into the feed-slot at the same speedl throughout the whole length of the slot.
- These feed-chains are tangent at their inner ends to the inner surface of the cap-plate c, and at that point all of them are the same distance above the Afeeding-lip a5.
- the feedchains are so supported that theirinnerends are all tangent to the continuation of the inner curved surface of the cap-plate, so that if the regular inner retaining-surface of the cap-plate were continued past the compressing-abutment a6 the chains d would each be
- the rear ends are supported at a higher level by the drivingsprockets d4, fast on the shaft d2, adapted t'o be driven at any desired rate by suitable means.
- the lower or feeding run of these chains grip the material more and more tightly in connection with the smooth feedinglip and positively force it into the feed-slot a4 at the same radial speed throughout the whole length of the slot.
- the portion ai is preferably made to closely hug the feed-chains near the edge of the compressing-abutment a6.
- Suitable annular depressions accommodate the feeding projections on the chains, that are made to aline longitudinally of the chains. ln this way the material carried into the cap-plate is released from the feeding projections at the point a6, and said material is positively scraped off the chains by the close-lying abutment a5.
- a series of substantially annular recesses are formed in the edge of the cap-plate at a5 adjacent the feeding-passage in the cap-plate. Each one of these annular recesses accommodates one of the feeding-chains, as is shown in Fig. 3.
- the chains extend over the plates d5, so as to form a practically con-
- the separate chains are accommodated by the formation of the cap-plate, which is substantially tangent to them at d5, while a slight relief is made at a, so that the chains can readily free themselves at this point from any material, which will then be carried along and incorporated in the bale.
- the inner surface of the cap-plate is so constructed that an axial section through the point just above a where the new material is compressed against the rotating bale will be a parabola whose axis is the axis of the press.
- the cap-plate is preferably designed for some particular feed of the bale throughthe press by the ejector-say one inch per revolution of the bale in the cap-plate.
- Theinner surface would in that case be the surface generated by the revolution of the forming parabola about its axis and its simultaneous uniform feed along its axis at the rate of one inch per revolution. ln case a number of feed-slots were employed the inner surface of the capplate between any two slots would be a surface formed as above, and these elements would be symmetrically placed about the axis of the press.
- the inner surface of the capplate may be constructed as a paraboloid of revolution. This involves small variation from the curved surface described above, which I term a parabolic helicoid, when the ejector-feed is comparativelysmall, and practically noue at all when a number of feedslots are employed.
- the presa-A uniform bat of fibrous material such as cotton
- This bat is compressed against the end of the forming bale at the edge of the feed-slot and thereupon revolves with the bale.
- the fins b5 on the baling-chamberare forced into the bale and grip the same, so as to insure its rotation with the chamber.
- the threads of the ejectorare also forced into the bale and grip it sufficiently so that the positively-rotating ejector can feed the bale forward lgonstantly at any desired rate.
- the threads c' and the fins b5 project into the bale enough and only enough to get the proper engagement with it under all conditions of operation, and their size will be such in practice that they will do this properly with the material on which the press operates.
- the bale formed by this press is self-binding or coherent without any external binding means, just as is the blanket or convolutionally-wound lap-bale, since its external layers are so nearly parallel to the axis at that point that radial expansion is resisted by the circumferential strength.of the fibers, and longitudinal expansion after the bale is once formed is prevented by the friction of the layers due to the great radial pressure between them.
- the bale as fast as it is built up within the cap-plate is a'coherent solid mass, in which the material does not materially change its position after it is on'ce laid on. If We consider the point a6 on the cap- IOO IIO
- the material laid on' at this point and nearer the vertex of the cap-plate forms a cylinder in the finished bale whose radius is the radial distance of the point a6 from the axis of the press.
- this point is also manifestly the vertex of the parabola through as.
- the width of bat fed into the slot up to the point 0.5 equals the axial distance of this part from the vertex O, and its weight bears a fixed ratio to this distance, since the bat is uniform and is uniformly fed into the slot.
- the cylindrical section of the bale formed thereby in a given time bears a fixed ratio to the square of the radial distance of a6.
- this bale-section which is the quotient of the two, bears a fixed ratio to the axial distance divided by the square of the radial distance of the point a6. This holds true of any point on the edge of the feed-slot. Since, however, the edge is a rectangular parabola and the axial distance of any point from the vertex divided by the square of its radial distance is a fixed ratio throughout the extent of the curve, the density of a cylindrical bale-section is a fixed quantity, no matter what its radius, or, in other words, the bale has a constant density throughout its whole extent.
- the bale issuing from the baling-chamber can be severed into lengths by any desired mechanism and can be covered and tied, if desired.
- Fig. 4 I have shown a modified form of cap-plate, in which two feeding-openings are formed along opposite sides of the cap-plate and on substantially the same axial plane. I have also shown two sets of sprocket-chains adapted, as they will be formed in practice, to positively grip the material supplied to them and feed it into the feed-slot at the same radial speed throughout the length of that slot. Each segment of the cap-plate between adjacent slots is formed by the revolution of the compressingabutment, similar to a6 in Fig. 2, about the axis of the press and its simultaneous movement along the axis at the rate at which it is desired to feed the bale through the press. Y
- my press could be fed with material in any other desired way by supplying material to the feed-slot in the cap-plate, and if during the operation of the press material was constantly supplied throughout the whole extent of the slot a bale would manifestly be produced having superposed ribbons of material the surfaces of which would be substantially a paraboloidal helicoid.

BALINGi-PRESS.
srncrrrca'rron forming part of Letters raient No. 672,394., dated April ie, 190i. Application filed February 16, 19051. Serial No. 47,570; `No model.)
To all whom t may cm2/007111,:
Be it known that I, HARRY L. DUNCAN, a citizen of the United States, residing in the city of New York, county of Kings, and State of New York, have invented a new and useful Improvement in Ealing-Presses, of which the following is a specification.
This invention relates to machinery for producing cylindrical bales of fibrous material by means of a relatively-rotating slotted capplate and baling-chainber; and it has for its object novel means for producing suoli a bale of material so that it will be su bstantially co'- herent or self-binding and of substantially uniform density from center to circumference.
The exact scope of my invention will be more particularly pointed out in the annexed claims.
In my copending applications, Serial Nos. 47,569 and 47,571, filed February 16, 1901, and Serial No. 48,130, filed February20, 1901, I claim such parts of my invention as are disclosed, but not claimed, in this case.
In the iigures of the drawings, in which like reference characters refer to the saine parts throughout the several views, Figure l is a sectional plan view of my improved press and feeder therefor, taken on line 1,'1 of Fig. 2. Fig. 2 is a transverse sectional view of the saine, taken on line 2 2 of Fig. l. Fig. 3 is a detail view, on a larger scale, taken on line 3 3 of Fig. 2, showing the construction of the feeding-chains for supplying the Inaterial to the capplate of this press and means for mounting the saine. Fig. et is a detail view, on a larger scale, showing a modified con struction of press, the View being taken transversely to the axis of the press near the point of the cap-plate.
In this case the cap-plate o, is formed with an inner surface substantially a paraboloid, as is shown by the cross-section along the axis of the press. This cap-plate is held stationary by being secured to heavy framing ffs. Just behind the cap-plate and having a bearing in the flanged extension ct' thereof is the screw ejector c, formed with an integral gear c3. The meshing gear a2 upon shaft a3, mounted in suitable bearingsf8 in the frame, may be rotated at any desired speed, so as to vary the speed at which the ejector is driven. Upon the inside of the ejector is formed the screw-thread c' of uniform pitch, but having the threads gradually increasing in height at the inner end. Directly behind c is the baling-chamber b, having a bearing-collar b' at the inner end. The annular flanges a7 as hold these two elements in position and are boltedto an extension of the frame ff. The gear b2 is secured to b, and just below it the frame f7 incloses the chamber b, so that it can revolve properly about its axis. The shaft b4, carrying gear b3, meshing with b2, can'be revolved at any desired rate by suitable means, and it serves to vary the speed of revolution of the chamber b as desired. Longitudinal ribs or fins b5 are formed on b and project into it, as shown. The press proper therefore consists of the substantially parabolic capplate Ct, which is stationary, the cylindrical screw ejector c, and the cylindrical balingchamber b, both of which revolve about their axes, which coincide with the axis of the capplate.
Feeding mandarme-A condenser-cylinder e, of foraminous or wire-net material, is rotated about its axis at any desired speed. Fixedly attached to the stationary shaft e' is the shield e2, which is supported adjacent the lower part of the condensencylinder. rlhese parts are supported in and surrounded by a casing e3, which supports the strip e5 of flexible material, such as rubber, adapted to press forward against the bat of material which collects on the cylinder. The flexible strip e4 is attached to the casing on the other side, and its lower edge is attached to the upper ends of a series of slides e6, mounted on the support e7 and adapted to be clamped in any position thereon by bolts and washers es, which work in connection with large openings in the support e7. The concentric pieces e6 can therefore be adjusted after removing the lower section of e3 adjacent thereto through a considerable angle about e and, as shown in the plan view, can vary the effective angle of the condenser c, which is active to collect material fed to it in a blast of airsupplied through an opening in the top of the casing e3. The function of these slides, of
which any desired number may be used, is to so adjust the condensing-surface of the cylinder that the bat of material collected thereon is perfectly uniform from end to end.
A suit- IOO ' tangent to such surface.

able doffer e9 operates in connection with the condenser-roll under the shield, as is usual in this art.
The air is exhausted from the inside of the condenser by an exhaust-pipe ew, connected therewith in a usual manner and also connected with some suction device. The bat formed is carried by an apron g, mounted on roll g, driven positively bythe shaft g2, so as to give the apron the same surface speed as the condenser-cylinder, and also passing over roll g3, loose on shaft g4. The apron rests on the plate g5, which is supported on the framing j" and on the heavylip a5 of the capplate. Adjacent to the feed-slot are the feedchains d, which have formed on their outer working faces slight projections or teeth, so as to grasp the bat of material and positively feed it forward into the feed-slot at the same speedl throughout the whole length of the slot. These feed-chains are tangent at their inner ends to the inner surface of the cap-plate c, and at that point all of them are the same distance above the Afeeding-lip a5. The feedchains are so supported that theirinnerends are all tangent to the continuation of the inner curved surface of the cap-plate, so that if the regular inner retaining-surface of the cap-plate were continued past the compressing-abutment a6 the chains d would each be The rear ends are supported at a higher level by the drivingsprockets d4, fast on the shaft d2, adapted t'o be driven at any desired rate by suitable means. The lower or feeding run of these chains grip the material more and more tightly in connection with the smooth feedinglip and positively force it into the feed-slot a4 at the same radial speed throughout the whole length of the slot. The portion ai is preferably made to closely hug the feed-chains near the edge of the compressing-abutment a6. Suitable annular depressions accommodate the feeding projections on the chains, that are made to aline longitudinally of the chains. ln this way the material carried into the cap-plate is released from the feeding projections at the point a6, and said material is positively scraped off the chains by the close-lying abutment a5. Thus a series of substantially annular recesses are formed in the edge of the cap-plate at a5 adjacent the feeding-passage in the cap-plate. Each one of these annular recesses accommodates one of the feeding-chains, as is shown in Fig. 3.
A heavy framework built up of strong steel plates d5, bolted together with spacing-blocks d to the frame members ff, supports the driving-sprockets d4 and the loose 0'uidimr- C a 23 D wheels d3, mounted on their axles d adjacent the cap-plate. Itwill be noted by referring to the detail View that the chains extend over the plates d5, so as to form a practically con- The separate chains are accommodated by the formation of the cap-plate, which is substantially tangent to them at d5, while a slight relief is made at a, so that the chains can readily free themselves at this point from any material, which will then be carried along and incorporated in the bale.
The inner surface of the cap-plate is so constructed that an axial section through the point just above a where the new material is compressed against the rotating bale will be a parabola whose axis is the axis of the press. The cap-plate is preferably designed for some particular feed of the bale throughthe press by the ejector-say one inch per revolution of the bale in the cap-plate. Theinner surface would in that case be the surface generated by the revolution of the forming parabola about its axis and its simultaneous uniform feed along its axis at the rate of one inch per revolution. ln case a number of feed-slots were employed the inner surface of the capplate between any two slots would be a surface formed as above, and these elements would be symmetrically placed about the axis of the press.
In practice the inner surface of the capplate may be constructed as a paraboloid of revolution. This involves small variation from the curved surface described above, which I term a parabolic helicoid, when the ejector-feed is comparativelysmall, and practically noue at all when a number of feedslots are employed.
Operation of the presa-A uniform bat of fibrous material, such as cotton, is formed by the condenser and is positively fed into the cap-plate at the same radial speed throughout the length of the feed-slot by' the feedchains d. This bat is compressed against the end of the forming bale at the edge of the feed-slot and thereupon revolves with the bale. The fins b5 on the baling-chamberare forced into the bale and grip the same, so as to insure its rotation with the chamber. The threads of the ejectorare also forced into the bale and grip it sufficiently so that the positively-rotating ejector can feed the bale forward lgonstantly at any desired rate. The threads c' and the fins b5 project into the bale enough and only enough to get the proper engagement with it under all conditions of operation, and their size will be such in practice that they will do this properly with the material on which the press operates.
The bale formed by this press is self-binding or coherent without any external binding means, just as is the blanket or convolutionally-wound lap-bale, since its external layers are so nearly parallel to the axis at that point that radial expansion is resisted by the circumferential strength.of the fibers, and longitudinal expansion after the bale is once formed is prevented by the friction of the layers due to the great radial pressure between them. The bale as fast as it is built up within the cap-plate is a'coherent solid mass, in which the material does not materially change its position after it is on'ce laid on. If We consider the point a6 on the cap- IOO IIO
plate, the material laid on' at this point and nearer the vertex of the cap-plate forms a cylinder in the finished bale whose radius is the radial distance of the point a6 from the axis of the press. Calling O the intersection of the press-axis with the cap plate, this point is also manifestly the vertex of the parabola through as. The width of bat fed into the slot up to the point 0.5 equals the axial distance of this part from the vertex O, and its weight bears a fixed ratio to this distance, since the bat is uniform and is uniformly fed into the slot. The cylindrical section of the bale formed thereby in a given time bears a fixed ratio to the square of the radial distance of a6. The density of this bale-section, which is the quotient of the two, bears a fixed ratio to the axial distance divided by the square of the radial distance of the point a6. This holds true of any point on the edge of the feed-slot. Since, however, the edge is a rectangular parabola and the axial distance of any point from the vertex divided by the square of its radial distance is a fixed ratio throughout the extent of the curve, the density of a cylindrical bale-section is a fixed quantity, no matter what its radius, or, in other words, the bale has a constant density throughout its whole extent.
It is manifest that many variations from the exact construction set forth could be made by the skilled workman and still attain the beneficial results of the construction that I set forth. The contour of the cap-plate need not be exactly parabolic, and the density and feed of the bat mightvary from what I have described. It is also manifest that for any capplate of curved outline some formation of bat could be readily arranged which when fed radially thereto would produce a bale of uniform density.
The bale issuing from the baling-chamber can be severed into lengths by any desired mechanism and can be covered and tied, if desired.
In Fig. 4 I have shown a modified form of cap-plate, in which two feeding-openings are formed along opposite sides of the cap-plate and on substantially the same axial plane. I have also shown two sets of sprocket-chains adapted, as they will be formed in practice, to positively grip the material supplied to them and feed it into the feed-slot at the same radial speed throughout the length of that slot. Each segment of the cap-plate between adjacent slots is formed by the revolution of the compressingabutment, similar to a6 in Fig. 2, about the axis of the press and its simultaneous movement along the axis at the rate at which it is desired to feed the bale through the press. Y
It is manifest that in such a pressv as this two sets of bat forming and feeding mechanism similar to the single set shown in Fig. 2 would be employed on either side of the cap-plate. The same construction of balingchamber and ejector could manifestly be employed in this case and the bale formed would be similar in character, as has already been pointed out.
While I have shown the ejector as coaxial with the forming bale, I do not wish to be limited to this construction, since the ejector would work equally well in any position relative to the bale so long as the threads upon the ejector impinged upon the bale to properly grip the same.
It will be manifest that various modifications of the mechanism shown in the drawings may be made. It would not be necessary, for instance, to have the entire cap-plate formed with an inner surface of paraboloidal form. The tip of the cap-plate might be constructed of another shape and might be fed with material in any desired manner so as to produce a center for the bale by means other than I have shown in the illustrations. A bat of desired cross-section could be fed into the slot adjacent to the paraboloidal portion of the cap-plate, so as to forin a part of the bale in this manner around a center or core madein any other desired way. The part ofthe bale formed by the paraboloidal portion of the cap-plate would of course be of substantially uniform density. Parts of my mechanism herein disclosed could be used without employing the whole, and I do not wish to be limited to the exact means disclosed in the drawings.
Instead of employing the bat -forming means and feeding means which I have disclosed in this case my press could be fed with material in any other desired way by supplying material to the feed-slot in the cap-plate, and if during the operation of the press material was constantly supplied throughout the whole extent of the slot a bale would manifestly be produced having superposed ribbons of material the surfaces of which would be substantially a paraboloidal helicoid.
While I have disclosed in this case the paraboloidal cap-plate as projecting outward from the baling-chamber, I do not wish to be limited to this arrangement of the two parts.
Where I refer to the inner surface of the cap-plate in the claims, I mean the working surface or the surface which compresses the material against the forming bale.
