SELF-FEEDER FOR BALlNG-PRESSES.

Specification of Letters Patent.

Patented June 12, 1 906.

Application filed August 1, 1905. herial No, 272.141.

To all whom it may concern:

Be it known that I CLARENCE E. Bowen;

a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Self-Feeders for Belingoi which the following is e specified tion.

This invention relates to self-feeders for baling-presses, end has for its object to produce mechanism of this character which efficiently, reliably, and expeditiously disposes the beling material in the press.

A further object is to reduce mechanism of this character which fiieds the belin material into the press in the form of a. Wei and effects the severance of such web within the case just prior to the in'ipoct on such web of the plunger.

A still further object is to produce mechanism of this character which accommodates itself to the varying conditions or kinds of baling inaterial so as to avoid the possibility of being choked if the web entering the haling-cese be exceptionally thick.

Another object is to produce means for retarding the baling material in case of an overcharge, and thus guardin against the formation of a web of such thic ltness or depth as to threaten choke e of the machine.

\Vith these 0 jects in view and others as hereinafter appear the invention consists in certain nove and peculiar features of construction and combinations of parts, as here inafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- Figure 1 is a side elevation, partly lJI'OliGfr sway, of a hailing-press equipped with selffeed attachments embodying my invention. Fig. 2 is an enlarged view, partly in top plan and partly in section, on the line II II of Fig. Fig.3 a vertical section on the line III III of Fig. 4. Fig. 4 is a section on the line TV IV of Fig. 1. Fig. 5 is a. vertical section on the lineV V of Fig. 1 end on the same scale as Figs. 2 to 4 inclusive. Fig. 6 is a detail perspeetiv'e'view oi the lower half orflbottorn of the movable guideway. Fig. 7 is a detail perspective view of theneedle-pointed knife.

In the said drawings, 1 indicates a balingnose of the usual rectangular form in crosssection and constructed of any suitable material, as tiie precise construction of this press press shown has a feed-opening 2 in its upper side and is rovided with e reciprocatory plunger 3, w llC-ll by preference is provided with the entifi'iction-roiiers 4 at the upper corners ofits face. The plunger, as usual, may he provided with the supporting-rollers 5 and is connected by the pitnien 6 to the crsnlepin 7, connecting e air of gear-Wheels 8, hrranged, prefereb y, within and projecting above and below the press,said wheels being mounted rigidly on a transverse shaft 9, journaled in bearings 10, secured to the bathingcase. Said wheels interrnesh with the gearpinions 11, secured rigidly on transverse shaft 1 2, journeled in the case and'equipped at opposite sides of the latter with gearwheels 13, intcrincshing with geer-pinions 14, mounted on it trans verse shaft 15,journeledin the baling-case,snid shaft carrying at one end a fly-wheel 16 and at the other a. belt-wheel 17, to which rotation is imparted through the medium of a belt. (Not shown.) As this plunger-actuating mechanism is simply on ordinary train of gearing and forms no indispensehie element of the invention, certain of the wheels shove referred to appear only in dotted lines, and only a single wheel appears where duplicates are described, it being reediiv understood that motion imported to the belt-wheel results in reciprocatory movement of the plunger, and in this connection it should be noted that the openings in the top and bottom of the billing-case through which wheels 8 project also accommodate the revolving crank-pin end the connected end of the pitman.

Near the front end of the feed-opening the side Walls of the haling-cese are cut away, as at 18, and secured to the outer side of each wall is an inverted-U-shaped frame 19, disposed verticelly, the vertical arms of said frame being at o posite sides of said openings, said arms o the frames being provided with vertical tongues 20, slidebly engaged by the grooved slide-plates 21, which when they occupy thElT'H'lOSt depressed positions project slightly above the top of the beling-csse by preference.

22 indicates a roll which by preference is longitudinally fluted, as shown, and has its spindles joufnsled in the slide-plates 21 end in a pair of swing-arms 2 1, having longitudinal slots 23 pivotslly engaging pins 25, projecting inward from the side walls of the huling-csse contiguous to the front end of the is unimportant in this connection. The feed-opening thereof, said swing=arms converging downward and rearward with respect to the bottom of the baling- 'ase for a purpose which hereinafter appears. Vertically above roll 22 the slide-plates 21 are provided with vertical slots 26. and fitting slidingly in said slots are boxes 27, held depressed by expansive coil-springs .28, occupying said slots and pr rising at their upper ends against the caps 29, vertically adjustable for the purpose of varying the pressure of the springs by capscrews engaging the slide-plates 21, the springs being retained in operative position by means of the guide-rods 32, which project vertically upward from the slide boxes through the sprin and caps.

33 indicates a periphmrally-fluted roll having its spindles journaled in sliding boxes 27 and engaging the longitudinal slots 34 of a pair of swing-arms 35, said swing-arms being pivoted at their upper ends on a transverse shaft 36, journaled in sliding boxes $37, mounted in vertical standards 38, secured to the opposite sides and externally of the baling-case, said shaft 36 being preferably vertically above the pivotal points 25 of swing-arms 21 and provided with a longitudinally-lluted roll 36 between said standards 38, and in this connection it should be noted that the swing-arms converge downward and rear ward with respect to the lower swing-arn'is. It will also be noticed that the sliding boxes 37 are held. yieldingly depre sed by mechanisin of the same character and arrangement as that described with relation to sliding box 27, and therefore needs no detail description. The swing-arms 24 are connected in the plane of their upper edges by the cross-plate 39, extending from a point adjacent to the roll 22 nearly to the upper or front ends of the arms.

42 indicates a plate connecting arms 35 in the plane of their lower edges and extending from a point a suitable distance from roll 33 to a point about vertically above the corresponding or rear end of plate 351, and journaled in said arms 35 and depending through an opening 43 in plate 42 are a series of rolls 44. plane of the lower edge of arms 35 from roll 33 to a point above and overlapping plate 42, and said plate 45 is provided with. arms 46, which pivotally engage the spindles of roll 33 and fit snugl} between the ends of said roll and said arms 35. The arms and their respective lixed plates and slide-plates constitute a guideway havingits delivery end adapted to discharge at varying altitudes, as hereinafter explained, and by reason of the fact that the upper swing-arms and their connections, which may be termed the top of the guideway, are held yieldingly depressed at each end it is obvious that the web of baling material passing between the guideways may vary in thickness witl'iout interrupting the feeding operation. it will also be apparent that upward-swinging movement of the bot- 45 is a slide-plate which occupies the I tom of the guideway viz arms 24, and the roll connecting the plates carried by said arms--willcause like movement on the part of the superposed roll and the top of the guideway, the spindles of said rolls sliding forwardly in the slots of said arms and the slideplates having like n'iovenlcnt with respect to the stationary plate, said parts moving in the opposite direction when said swing-arms are again (lt])lt::(tl. ln this connection it will of course be understood that the upwardswinging movement of the bottom of the guidcway is accompanied by upward movement of the slide-plates 21 and that the weight of said slide-plates and the connected parts return them to their originally-depressed positions.

47 indicates a horizontal cross-bar rigidly connecting the slide-plates 21 rearward and near the upper surface of the roll 22, and said plate 47 is provided with. a narrow transverse slot 48 for a purpose which hereinafter appears. Secured rigidly to plates 21 above plate 47 and rearward of and in about the same plane as the center of roll 32) is a horizontal plate 49, which projects rearward beyond. the guide frame it! a suitable distance for a purpose which is hereinafter explained, and said plate is provided with a transverse slot 50, disposed vertically above slot 48, but of somewhat greater width, a pair of rolls 50 being journaled between plates 4T 49 at the ends of slot 48.

51 indicates a pair of vertical guide-bars arranged inward of the rear arms of guideframes 19, so as to provide slots 52, wherein slide-plates .21 may recipro ate, the bars 5'] being widened at their upper ends, as at 53, so as to fit snugly against said guide-frames and be secured thereto by bolts 54. The lower ends of said bars 51 are connected by cross-brmes .35, and the bars 51 are provided at their inner sides with. grooves 56 in the vertical plane of slots 48 and St), and engaging the grooves of said bars are the tongues 57 of the transverse frame 58, equipped with a depending knife in the form of a series of sicklesections 59, having their beveled edges disposed forwardly and provided at their points with depending needles tit). This knife-carrying slide-frame is normally held elevated in the position shown. in Figs. 3 and 5 by retractile springs (51, connected at their lower ends to said slide and at their upper ends to bolts 54, as shown most clearly in the last-named figure. Projecting upward from the center of the knife-carrying slide is a bifurcated arm 62, and pivoted therein is the front end of a lever comprising arm 63 and fulcrum-rod (34, said rod being journaled in the front pair of arn'is of the standards 19, as shown most clearly in Figs. 3 and 4, the leverarm being braced from the fulcrum-rod by means of braces (55.

arms mountedon the ends of fulcrum-rods 64 i IO to sprocket-Wheel 73, secured rigidly on the end of the shaft 74, journsled in standards 38 and equipped between said standards with a transverse roller 75, sprocket-wheel F3 having preferably half as many teeth as sprocket- Secured rigidly on one end of said shaft s bevel gear-wheel 76, having the some number of teeth as sprocket-wheels 73 and meshing with a bevehgesr 'Z'Tef twice the number of teeth, said Wheel 7? being secured upon the upper end of shaft 78, iournaled in bearings 79, secured to standards 38 and 80, secured to the sides of the hailing-case. Secured to the lower end of said shaft is a bevel-gear 81, meshing with bevel-gear 82 on the longitudinally-extending shaft 83, journsled in bearings 84 and 85, secured to the billing-(351st), bevel-gear 86 on the front end of shaft 83 meshing with bevel-gear 87 on the end of shaft 9, the arrangement being such that with each compression-stroke of the plunger there will be one revolution of omnisarms 68, and, through the action of said arms on the rook-lever, one depression of the cutting mechanism, it being noted in this eon- 3 5 nection that it requires only about one-tenth of a revolution of said arms 68 to effect the full depression of the cutting mechanism, and

consequently that the action of the letter is at a ratio of about ten to one with regard to the speed of the plunger, the springs 6i reels voting the cutting mechanism the instant after said arms 68 clear rollers 67 in order that the advance of the Web of baling n e terisl shall not be impeded by and piief'fip s giiin st Bet-Ween standards l snd' the side Wells are provided with uptvsrdextensions 88, which form sides for the vertiesllirmovable guideway hereinbefore described for the purpose of insuring the passage of the web of healing materiel passing through said guidcway down into the bailing-case through the feed-opening thereof.

89 indicates standards rising from the beling-ease and dis osed apart a distance ex- 5 5 ceeding the widt of the letter.

W 90 indicates a transverse feedroll having its shaft 'ournaledinstandsrds S9 at e suitable heig t above the baling-case, and 91 a similar roll having its shaft journaled in vertical slidahle boxes 92,,1nounted in the standerds and held depressed by sprin s 93.

94 indicates e'second set of standards erected upon the bailing-case and shout the same distance apart as standards 89, and mounted slidingly in the upper ends of standards 94 are slidebloeks 95, held yieldingly depressed hy springs 96.

97 indicates a pair of standards erected upon the front end of the billing-case and "ehnn'eeted by a, cross-rod 8, and pivotslly mounted on said eross-rod end projecting forward therefrom are side bars 99, connected at their front ends by at cross shaft 166 with coincide-nth; pivoted legs 101 102, the former being employed when the frame 99 occupies a horizontal position and legs 18;? when said frame occupies the inclined posi= tion shown by dotted lines, Fig. l. 'See ured rigidly on shaft 100 is a. roller 183, connected by an endless cross-slst or equivalent eonveyer 104 to the roller 1G5, contiguous to and in a hi 'her plane than roll 90, the shaft of said roller 195 being journsled in side boards 106, connecting standards 89 and 94, similar side boards 10? extending forward from standerds l end mounted on cross-rod 98 at the outer side of sides 99 of the pivoted frame, it roller 108 being journaled on red 98 between the upper and lower strands of the endless conveyer in order that said strand may bend around said roller when said pivoted frame is swung downward to the position shown in dotted lines, a similar roller 109, carried by and between standards 97, underlying the lower strand of said belt as a bending-point for such strand.

r 7 iii) indie-sites a frame connecting side hosrds 1G6 and extending from stendsrds 89 to and slightly forward of standards 9-1, and depending from said frame are shsrpened pins 111 for the purpose of preventing an overcharge of behng materiel iron; "seeing to' fo'l'ls 90 end 91. As long as the fee is uni- "form these ins do not come into contact with thebs ing materiel, because they are shielded by the board 112, pivoted, as at 113, to standards 89 and provided With holes 114, receivin stander s 94 extending obliquely upward, as at 115, for the purpose of reducing the mess of bsiing materiel heing conveyed upon the endless conveyer to a uniform thickness. in case the volume of material is too great it will press against the under side of board 112 and swing the same upwardly, so as to expose the points of the pins, so that thelstter wili set as a retsrder for the upp'er part of the Web of the rneterisl and permit of the passage of theproper volume only to and between rolls 'QUsnd hseid web of materiel passing thence into the downwardly and rearwsrdly extending 'guideivey;consisting of the bottom 116, side senile 11?, and top wall 118, the friction between the web of material and said guideway being reduced to the minimum by means of the roliers 1 19, depending through the top we11,snd the upright rollers 126, projecting inwardly of the side walls, it being noted in "1th is eonneotion that this guidewny eonverges resrs'erdly for the purpose of condensing the material and reducing its width to approximately that of the movable guideway hereinbefore described.

Referring now particularly to Figs. and 5, it will be noticed that shaft 74, driven as hereinbefore explained, projects some distance beyond one side of the baling-case, and mounted upon said shaft at a suitable point is a gear-wheel 121, meshing with a similar gear 122 on a short shaft 123, said shaft being connected by a universal joint 124 to one member of a telescopic or eXtensible and contractible shaft 125, the opposite end of said shaft being connected by a universal joint 126 to the contiguous end of shaft 36. This telescopic shaft universally connected, as ex plained, is provided in order to accommodate the rise and fall of the roll 36. .127 indicates a sprocket-wheel mounted on shaft 74 and connected by a chain 128 with a sprocketwheel 129 on a short shaft 130, disposed in the horizontal plane about half-way between the planes occupied by roll 22 when in its depressed and elevated positions, and said short shaft 130 is connected by a universal joint 131 to one end of a telescopic shaft 132, the other end of said shaft being connected by a universal joint 133 with one end of the shaft of roll 134 indicates a gear-wheel mounted on shaft 130 and meshing with a gear-wheel 135, mounted on a short shaft 136, connected by a universal joint 137 with one end of the telescopic shaft 138, connected by a universal joint 139 at its opposite end to the contiguous end of the shaft of roll 33. This arrangement provides for a rotary movement of the rolls 22 and 33 without interfering with their vertical movement. 140 indicates a second sprocketwheel mounted on shaft 74 and connected by a chain 141 with a sprocket-wheel 142 on the extended end of the shaft of roll 90, and said shaft is provided with a gear-wheel 143, meshing with the similar gear 144 on the short shaft 145 ,universally jointed, as at 146, to the telescopic shaft 147, universally connected at its opposite end, as at 148, to the contiguous end of the shaft of roll 91. Also mounted on the shaft of roll 90 is a sprocketwheel 149, connected by a chain 150 to the sproeketwheel 151 on the shaft of roller 105 of the endless conveyor.

Through the medium of the gearing described the various shafts of which are journaled in. boXings carried by a skeleton frame 151, projecting from the baling-case and of the type shown or of any other suitable or preferred type, it will be apparent that the conveyer and the rolls will travel continuously in the directions indicated by the contiguous arrows and in consequence will feed the material, as hereinbefore explained, into the baling-case from the movable guideway. In such operation it will be noted that as the baling-plunger advances its antifriction-rollers 4 will engage the lower edge of the swingarms 24 of the movable guideway and will cause the same to swing upward without interfering with the movement of the web of baling material through said guideway other than raising said web of material and at the same time the superposed roll 33 and the top of said guideway. It will also be noticed that just before the balingplungcr has made half its compression-stroke that is, at the moment when the upward movement of the movable guideway ceases arms (53, moving in the direction. indicated, engage the lower sides of said rolls 67 and operate the rocklever to effect the downstroke of the cutting mechanism. This downstroke takes place as the parts are proportioned about ten times as rapidly as the plunger moves and occurs, as above suggested, at the moment that the upward movement of rolls 22 and 33, and consequently slide plates 21 and bars 47 and 49, ceases. As a result of this downward movement the needles and knife pass successively through slots 50 and 48, the lastnamed slot being narrow, so that its rear edge shall form, in effect, a stationary shearing surface whereon the knife shears the web of baling material contiguous to the rear sides of rolls 22 and 33, it being understood that the needles depending below the knife act as entering wedges for the points of the knives in order that the latter may perform its function most efficiently and reliably. Furthermore, by opening up such way they take the impact of the baling material from the extreme points of the knife, and thus preserve it in a sharpened condition longer than would be the case if the needles were not employed.

Immediately the cutting action is finished arms 68 clear rollers 67 and permit the springs 61 to instantly reelevate the cutting mechanism to its original position, where it remains until the plunger has completed its stroke and been withdrawn to its original position and is again moving on its next compressionstroke to reelevate the movable guideway. Immediately the cutting mech anism has been withdrawn, as hercinbefore stated, the continuously moving plunger forces that portion of the baling material severed from the web through the case until it has passed the retainers 1.52, which prevel'it it springing back materially as the withdrawal action of the plunger takes place. As the plunger in its withdrawal movement asses forward of the su erposed rolls 22 and 33 the latter, with slidi plates 21, move downward, and thereby cause plate 411 to press downward into the baling-chamber that portion of the front end of the web of baling material which, under the continuously-moving feed-rolls, is projected beyond the same during the rear half of the compression and the first half of the withdrawalstroke of the plunger-in other words, that ortion of the web of heling material which?" res accumulated at the delivery side of the feed-rolls before the latter have been again depressed to the bottom of the balin -case.

From the above description it will e ep parent that I have produced 3 self-feeder fer baling-presses embodying the features of edvantege enumerated as desirable in the state ment of the object of the invention and which obviously may be modified in its form, proportion, detail construction, and errangement of the parts without departm from the principle of construction involve Having thus described the invention, what I claim as new, and desire to secure by Letters Potcnt,'is
