This invention relates to machines books or stacks of sheets of paper by means or a resilient tubular binder of'the type such as shown, for instance, in the United States patent to Douvry, No. 1,970,285, issued August 14,1934;
The binder of the Douvrypatent,-whichonly one of the types of binders which canbe used in connection with the present invention, comprises aback having a number of fingers extending therefrom and curled to a tubular form. The material has'suflicient elasticity to permit the fingers to'spread open sufiiciently to receivea stack of pages, without exceeding the elastic limit of the material so that upon-release the fingers will resume the curled form under their own resiliency. l
The machineof the present invention is provided with means for holding the back,as' the curled fingers are being uncurled to receive a stack of pages and for permitting the recurling of the fingers under their own resiliency until they pass through aligned perforations'in afstack of pages to be bound.
It is one of the objects 01 the present invention to provide a machine of the above mentioned character which is capableof high speed opera,- tion and which can be used with binders of different diameters with a minimum of adjustment of the machine. 7 It is a still further object of the present invention to providenovel and improved mechanism forspreading or uncurling thefingers of the curled comb. In accordance'with the prior prace tice, of uncurling binders 'of the type here mvalved, as exemplified, forinstance, in the patent to Nelson, et al., No. 2,108,136, issued February 18, 1938, it was, necessaryfirst to position a curled comb or tubular binder in the machine'and then move arod lengthwise into the binder, which rod is' then moved at right angles to the axis of the binder to uncurl the same. Thereafter, when the book has been bound, the rod must be retracted from the binder before the binder can be withdrawn from the machine. It is one of the objects 01 the presentinvention' to provide a machine of the above character which can first grip the rings of the binder to uncurl the same and then, by a continuous operation, uncurl'the fingers, thereby eliminating the-operations of in serting a rod through the binder and then ultimately withdrawing the rod. I
In accordance with the principles of the present invention the machine is provided with an operating shaft and a number of mechanisms-successively driven a continuous operation of the shaft, "one or the mechanisms being driven from the shaft ;by a ,cam and-'the othermechanism teeth or fingersof the binder against side movement as theyrecurl following anuncufling operation Bylthis: arrangement the ends or the recurling fingers are always properly spaced'so that if the perforated stack of pages is properlypositioned with respecti to two of the fingers then all of the fingers are in'proper positions to enter the' perforationa J i a f The attainment of theabove and further objects ofithe' present invention will be apparent from =;the 'following.- specification taken in conjunction 'withthe acco' panyingdrawing's form ing apartlthereofiq Inthe drawings: w I Q Figure 1 is a front view of a machine embodying the present invention; I V v Figure 2 is a perspective-view of one'binder that can be used dn'the-machine of Figure 1 1 Figure-3 is a sectionalview taken along the line a 3-3 01' Figure l and' lookingin the direction" of illustrates ,a', typical binder the arrows Figure 4 is an end view of the'comb feed mechanism of Figure 3, showing the mechanism in an alternate position; a 1 Y Figure'5 is a fragmentary sectional view taken along thejline 5-5 of Figure 3' and showing the spreader hooks in one position} Figure 6 isa-viewsimilar'to figure 5showing the spreader hooks=inf an alternate position;

Reterence may first be had toFigur'e'2, which y t be used with the present machine. The, binder I consists of a back; portion 2. and a plurality. of parallel fingers or 1 rings, 3ta'integral therewith, and uniformly spaced from one another as indicated atL The binder is made of suitable materialgwhichcan be curled into a longitudinal tubularrorm, as shown,
andwhichhas suflicient fiexibility'tp permit c sectional view extend- "showing the mechanism in its next succeed of the. spreader operating block to figures of the drawing illustrating the binding machine. The binding machine 6 has a right hand end frame I and a left hand end frameaof a similar shapes and secured together by a" front rail 9 and a rear rail Hi, the rails being secured to the end frames by suitable machine screws or bolts. A front top plate I2 is bolted to the-top of the end frames 1 and 8 and extends the full length of the machine. This plate is appreciably above the front rail 9, there being a space l3' between thetop of thefront rail 9 and thebottom of the front top plate- IZ. The front top plate has a number of parallelslots' I5 formed at" the rear thereof and uniformly spaced apart, the spacings between the "slots-being substantially equal to the spacings 4 between adjacent rings 3 of the binderL' 'Arear top-plate I8 is also bolted or otherwisesecured to the end frames and extends forward from the rear .ofthe'machine to. a position almost but not quite at the rear edgeiof the top front'plate l2. so that there is a longitudinally extending slot. betweenthe front and rear top plates. This slot is filled-by a thin tempered tool steellspring spreader finger plate ;.that'is'screwed to the forward "edge. of thereartop plate I... The: spreaderfinger plate 2|! hasa number of spacedapartaligned spreader fingers 2| integral therewith and each of'which extends vertically upward from the rear top plate 18. The istance, between the. centers of the spreader fingers 2| is equal to the distance between centers ofadjacent spacesbetween fingers 3 ofthe binder The width of the spreader fingers 2l-is slightly less than the width of the spaces 4 between-'the'flngersj of the binder I, as may be seen from Figure 5. As maybe seen from Figure. 7, the fingers 2| are, opposite the slots l5.- g V A pair of rear bearing boxes and av pair of front bearing boxes are bolted to the underside of the. rear top plate It and project downwardly therefrom; ;A 1 pair 1 of operating rams 28-48 are mounteddorlongitudinal 1movement in the bearing boxes, each; ram being supported in a front and a rear bearingbox, as is apparent from Figures 3 and '7. The rear 'ofeach operating ram is threaded'and .extends-rearwardly of the rear rail l0, which rear rail is provided with oversized openings through which the operating ,rams extend. Therams are adapted for. longitudinal movement in thebearing boxes, and are provided Withadjustable' lock nuts 30 which abut against the re'arfbearing boxes 24 to. lim'itthe extent of forward movement of the. operating.
rams, as illustrated in Figure 9. Each operating ram includes an enlarged inter.- mediate portion; 32 having a milled channel.- shaped slot'33 therein in which a square head 34 fits closely and The spreader operating block has a cylindrical projection or pin 35 extending forwardly thereof for engagement by an operating yoke 31. Therefare two operatingyokes 31 both slides freely.
of which'are keyed to a rotary operating shaft 38 that is journalled in the end frames 1 and 8. Each operating yoke-31 has an enlarged head 40 at the top thereof, which head has an arcuate slot 4| formed therein, the are being curved about the axis of the shaft 38 as a center. The pin 35 extends into and rides freely in the slot 4|. The enlarged head 40 prevents the spreader operating block from dropping out of the channel slot 33. A spreader operating cam is integral with the operating yoke 31 and includes a cam surface 46 curved alongian arc of a circle having its center coincident with the axis of the shaft ;3 8, and includes also a cam surface 41 extending radially inwardly from the surface 46. '15- At its forward end each operating ram 28 has a downwardly projecting support 50 integral therewith for supporting a spreader hook bar 5|.
The spreader hook bar 5| is adjustably locked tothe supports 50 of the two operating rams 28 many desired manner, as by machine bolts 52. 'Tojfac'ilitate vertical adjustment, the spreader hook bar is provided with elongated holes 53 for receiving the bolts 52, which holes are of a Width only very slightly in excess of the diameter of the shanksof the bolts 52; An adjusting lock screw 54. threads through-the bottom of each spreader hook support 50. andbears against the spreader hook bar 5| for accurately positioning the same. By this arrangementithe spreader hook bar may be adjustedverticallywith great accuracy, but is capable of only oneposition lengthwise of the ch e- 1 The operat' g rams, ,together with the spreader hook bar secured 5 thereto; are biased to their rearmost position, which is the position illustrated in Figure 3, by a pair of springs 55. Each spring 55 is secured at the rear to a projection .or;-pin 56extending from the rear bearing boxes 24, which are stationary, and at its front .to a pin .51 secured. to.v the support 50 of the operating ram,.
v The spreader'hock bar5l has anumber of spreader hooks 60 secured thereto. Each spreader hook comprises a spring wire bent to a U- shape withv the ends of the wire then further brought together. into contact, as-indicated at 51 (Fig. .5). The top'ends of each wire are bent outwardly, as indicated at .62. Each wire is secured to the spreader hook bar 5| by a screw 63, the head of which bears against the bight portion of the spreader hook, and the shank of which threads into the. spreader hook support. The sides, of the spreader hooks 60 are maintained imposition converging towards one another by short spreader hook supporting pins that are pressed into holes inthe spreader hook bar and project slightly therefrom. Each spreader hook 60 extends through a slot I5 to a position above the top plate 12. V The distance between the outermost edgesof the outwardly bent parts 62 of each wire is only very slightly less than the width'4 of the slotsbetween adjacent fingers of thebinder I, so that when the spreader hooks 60 are in their normal position the binder i may be positioned over thespreader hooks with the ends 62 of the spreader wires extending into the spaces 4 between adjacentrings of the binder. The endsof the respective spreader hooks are in alignmentwith-the: spreader fingers 2|, as may be seen in Figure'5. The 'spacings'between adjacent spreader hooks is equal to the spacing of the slots .15 in thetop. plate 12. and equal to the spacing oftheslbts 4 between the rings s of the binder;
Two spaced gear racks I5 are formed on the underside of the bar10 and mesh with needle operating rack segments 11 at the ends of levers I8 mounted for oscillating movement on a shaft I9 -journ'alled in the end frames I-8 'near'the front thereof.
Tempered steel spreader pins or needles Iii-are secured to the needle bar I and project-rear wardly thereof. These pins are press fitted into holes in the needle bar, and are in alignment with I one'another and spaced apart so'that the pins 8| are opposite the centers of the respective spreader hooks 60. The rear or spreading end of each pin 8| is rounded off or tapered to a point as indicated at 04. Each of these pins is adapted to enter between the arms of a spreader hook 60 for spreading the arms apart from the position illustrated in Figure to the position illustrated in Figure 6.
Each lever I8 extends below the shaft I9 and has an operating rod 81 secured thereto by a pivot pin 88 which also receives a spring 89, the opposite end of which is pinned as at 90 to a stationary part of the machine in order to bias the lever I8 to the position illustrated in Figure 3. The rear of the rod 81 is screwed to a yoke 9I adjacent the cam 45. A pair of tines 9292 of the yoke 9| ride freely on the shaft 38 to support the rear of the rod and yoke combination 81-9I. The cam parts 46 and 41 of the operating yoke 32' are adapted to bear against a roller 48 carried by the yoke 9| for operating the yoke, in a manner which will be apparent asthis description proceeds. A collar 49 screwed to theshaft 38 adjacent each yoke 9| holds the yoke 9| against sliding lengthwise along the shaft 38.
The operating shaft 38 may be rotated in any desired manner, as by an operating arm 93 keyed to the shaft 38 and pivotally connected to an operating link 94 which may be reciprocated in any desired manner, as by a foottreadle.
A hopper is provided at the top of the machine for holding the curled combs, and a feed mechanism is provided for feeding the combsfrom the hopper one by one and automatically placing the fed comb in proper position for uncurling. The hopper is indicated in general by the reference numeral I00. The hopper comprises a supporting base I 0| which is adjustably secured ,upon
the rear top plate I8, and includes right hand and left hand end members I03, and an inclined front plate I04. A back plate I 06 is secured to the two end members I03, and extends across the rear of the hopper in a generally upwardly and inclined direction, as illustrated in Figure 3. Triangular end plates I08I09 are secured to the back plate I06 in any desired manner, as by machine screws I I0. A slotted front closure plate H2 is adjustably secured to and extends between the triangular end plates I08-409. For this purpose each of the end plates is provided with an oversized slot H3 at the front edge, through which slot locking screws II5 extend. The inner end of each locking screw is threaded into'a boss II 6 on the front closure plate H2.
a knurled head I I8 for turning the screw. The s'crewsII5 are screwed intothe bosses H6 and thus lock the plate H2 in its adjusted position.- The plate may be'adjusted both vertically and angularly. ,The front closure plate II 2 has a number of'leafsprings I secured thereto and extending beyond the bottom thereof. The front of the plate II2 has a number of rectangular slots I2I thereinopposite the respective springs I20, to permit the springs I20 a greater freedom of flexibility. The position of the plate H2 is adjusted until the springs I20 are above the inclined front plate I04 an amount suificient to hold the combs against freely rolling out of the hopper and yet suiiiciently far from the inclined frontplate I04 so that by the application of a small pressure against a, comb the springs I20 are-flexed out of'thenway to permit the escape of the comb. g r
Atriangular aligning plate I 24 is positioned within the hopper. This aligned plate is mounted on a-shaft I25 that can be slid from left to right within the hopper to position the plate I24 ata desired distance fromthe inner surface of the end plate I08, that distance being made equal to the length of the combs being used at the time. The shaft I25 extends through the end plate I09, and is-locked in place by a split clamp I 21, the lower arm of which is welded or otherwise securedto the outside of the'end plate I09, and
the upper arm I28 of which may be clamped towards the lower arm to lock the shaft I25. For this purpose ascrew I30 threads into the lower arm of theclamp and bears against the arm I28, the screwbeing adapted to be turned by a pin I3I. The plate I 24 prevents shifting'of the combs within the hopper and assures the positioning of all combs with their ends bearing against the inner surface of the plate I08.
Binder feeding means, in the form of an escapement mechanism, is provided for advancing the combs I from the hopper, one by one. This escapement. mechanism includes a shaft I journalled in the end members I03 of the supporting base I0 I, and provided with a trip handle I36 keyed to one end thereof outside ofthe hopper and havinga finger portion I3'I for actuating the same toturn the shaft I 35. A coil spring I 38 is provided for returning the escapement mechanism from its operated position illustrated in Figure 4, to its normal position illustrated in Figure 3. A number of discharge leversv I are secured to the operating shaft I35. Each of these levers includes a radially extending portion which is press fitted through a radial hole in the shaft I 35, and includes an arcuate portion I 4|. The levers I40 are spaced along the shaft I35, there being five such levers on the machine here illustrated, as may be seen from Figure 1. Opposite each, lever the inclined front plate I04 has 'a slotI43 through which the lever I40 can move. 7 Each slot is of a width only sufiicient to permit free movement of a discharge lever I 40. The levers I40 are positioned in the machine so that. the top curved surface I 4| terminates substantially at the level of the top ofthe lowermostcomb I, within the hopper. When the lever I36 is actuated to rotate the shaft [35. in a clockwise direction the aligned levers I40 force forward to discharge the lowermost comb. At.
the same time the curved portions I 4| of the Each locking screw I15 has a head'l II that bears against'the corresponding plate I08 01- I09, and
4- levers i4fl'support the remainingcombs and preJ-f vent theirescapesfrom the hopper.
The hopper is mounted on. the reartop plate 18 he; machine screws M8, the heads of which rest on a flange on the end members Hi4, and the shanks of which extend through oversizaed slots H8 in the flanges of the end members. The hopper is thus adjustable forwardly and rearwardly on the base [8. Two threaded adjusting screws 15G extend rearwardly from the supporting base Ill at op-- posite ends thereof. Each screw I54 extends through oversized holes in a pair of lugs I52 that are secured to therear top plate 18. A knurled nut I53 threaded on each screw l rides between the lugs I52, sov that by adjustment of the knurled nuts I53 the hopper maybe advancedor retracted onthe plate l8 to position the vertical front edge I58 of the hopper at exactly the requisite distance from the fingers of thespread'er finger plate 20. This distance is adjusted so that the back 2 of the binder fits snugly between the spreader finger plate 20 and the vertical front edge l53' of the hopper, while the curled fingers of the binder extend through the spaces between adjacent fingers 2!; This distance differs for binders of different diameter. I
An explanation will now be given of the mode of operation of the machine described. Precurled plastic binders all of the same length are placed in the hopper 100, and the aligning plate I24 is adjusted to the left, as seen in Figure 1,
to such a position that the binders fit within the" hopper with the ends of all of the binders bearing against the end plate I 08. The front closure plate I I2 is adjusted vertically so that the springs in just prevent the passage'of the lowermost binder from the hopper. The position of the entire hopper on the plate I! is then adjusted forwardly or rearwardly of the spreader finger plate 28 until the vertical front edge Hill of the front inclined hopper plate I04 is at exactly the requisite distance from the spreader finger plate 20. This adjustment is efiected by turning the nuts I53. Thereafter the position ofthe hopper is fixed by locking the bolts I48. The machine is now ready for operation. I
The operator first feeds a binder into position by moving the trip handle I36 downwardly, whereby the discharge levers I40 force the lowermost binder I out of the hopper. At this time the curved portions l4| of the dischargelevers prevent the succeeding binders from falling out of the hopper. The binder thus released rolls down the inclined front plate I04 until the binder strikes the spreader finger plate 20. At this time the spaces 4 between adjacent rings of the binder are opposite the respective spreader fingers 2| so that the ringsof the binder pass into the spaces between adjacent spreader fingers 2!. The back 2 of the binder thus reaches a position opposite the space between the vertical front edge I58 of the feed mechanism and the spreader finger plate 20, and then falls into the position illustrated in Figure 3. At this time the bent parts 62 of each spreader hook 60 are in the'position illustrated in Figure 5, so that the binder rolls over the top of the spreader hooks and ultimately assumes the position illustrated in Figure 3 wherein the ends 6! of the spreader hooks are in the spaces between adjacent rings of the binder. 3
The machine is now ready for operation to spread the binder. To effect this operation the operator pulls downwardly upon the link 94, in
any desired manner, as by a foot. treadle. thus causing the operating arm 93 to rotate. the operating shaft 18 in a clockwise direction, as seen in Figure 3. During the initial rotation, of the operating shaft 38, resulting in turning of the operating yoke 31, the arcuate slot 4| of each yoke rides around the pin 35,so that no motion of the operating rams 23 is produced. During thisinitial clockwise turning of the operating yokes the cam surface 41 of the operating yoke bears against the cooperating cam surface or roller 48 on the yoke 9| andforces the yoke 9| to the right as seen in Figure '3. This produces a counter-clockwise rotation of the levers "about the shaft 19. The gear segments H of the levers 18 operate on the gear racks I5 of the needle bar Ill and move the needle bar to the left from the position illustrated in Figure 3 to that illustrated in Figure 8. During this leftward movement of the needle bar '10 the needle bar is still supported by the enlarged heads 13 of the machine screws 12, Rearward movement'of the needle bar '10 causes the rear ends of the needles 8] to enter the spaces between adjacent prongs or tines of each spreader hook 6B and spread the free endsof the spreader hooks from the positions illustrated in Figure 5 to the positions illustrated in Figure 6. The ends 62 of each spreader hook thus enter the adjacent rings 3 of the binder so that each ring} of the binder receives the outwardly bent part 62 of the two adjacent spreader hooks. After the rod 81 has been moved a short distance to the right to spread the spreader hooks 60 as above set forth, the arcuate cam surface 46 engages the roller 43 of the yoke 9! so that upon further rotation of the operating shaft 38, and with it the operating yoke 31 the cam 45, the cam surface 46 retains the rod 81 in the position to which it has been moved against the action of the return springs 89. At this time the lefthand end of the arouate slot 4! engages the pin 35, as seen in Figure 8, so that upon continued rotation of the operating shaft 38 the operating yokes 31. acting upon the pins 35 force the operating rams 28 rightward against the action of the return springs 55. This forces the support 50 and the spreader hook bar 51, carrying the spreader hooks Bil, to the right. The spreader hooks ride upon the spreader pins 8| so that the spreader hooks are maintained spread. The bent back portions 52 of the spreader hooks thus pull the rings of the binder to the right. At this time the back 2 of the binder is held by the spreader fingers 2| of the spreader finger plate 20 against forward movement. The respective rings of the binder are thus uncurled.
The operator may then position a stack of pages I69 having aligned perforations immediately in front of the spreader finger plate 20, with the aligned perforations H0 in a position to receive the free ends of the fingers of the binder, as illustrated in Figure 9. The foot 'treadle is then gradually released, therebypermitting the springs 55 to return the operating rams 28 to the position illustrated in Figure 3. This causes the spreader hook bar 5| to return to the position illustrated inFigure 3, and thereafter causes the needle bar 10 also to return to the position illustrated in Figure 3 whereby the spreader hooks are first returned to their rearmost position and then the needles iii are withdrawn "from between the prongs or tines of the spreader hooks to permit the spreader hooks to return to their normal position, as illustrated in Figure 5. The book with the pages bound therein by the binder may then be removed from the-machineby merely .lifting upwardlyon thesame. r;
The lock nuts 30 are set for each size of binder so that the forward motion of the operating rams, and with it the spreader hooks, is limited to such an extent that the fingers or rings of thebinder will be spread sufiicientlyto permitinsertion of the pack of sheets but withoutallowing the ends of the rings ofthe binder toescapefrom under the spreader hooks. 1. ,1 I
In using rings of comparatively large diameter the requisite movement-of the ram to producethe necessary uncurling of the fingers must'be-comparatively great. At such times it is necessary to guide the free ends of jthetuncurling rings of the binderagainst sidemovement, becauseif any side. movement, takes place then: the; free; ends of the fingers may not=be in proper positiomupon recurling of the binder,- to enter the aligned holes in the stack of pagesgto be, bound. It is :tobe noted that the spreaderhooks 60. perform "the function of maintaining the uncurled teeth of the binder against side movement, and that during the recurlingoperation the rings of the binder are maintained in proper alignment with respect to one another, and therefore ,with respect to the perforations I70 in the stack of pages to be bound. The spreader hooks 60 are themselves maintained against any possible side movement during the 'uncurling or recurling operation by the slots l5 in the top plate 12, since the spreader hooks ride in these slots duringtthe forward andbackward movement of the spreader hook bar- 5|. ,The
needles or pins 8| which spread the spreader hooks also maintain the spreader hooks properly spaced and in proper alignment during thetoand fro movementof the1spreader-ihook bar. -'I'hus the spreader hooks (ill prevent'side movement of theaends of the binder while thesameisrecurling.

fingers extending between the binder back 2 and one of the covers, or end sheets of the book or stack of pages. The'back 2 of the binder thus lies between the spreader finger plate 20 and the vertical front edge I58 of the hopper assembly. Thereafter, upon rotation of the operating shaft 38, the spreader hooks are first spread togrip the rings and then the spreader hook bar is moved forward to uncurl the rings and permit removal of the stack of pages from the binder while the spreader hooks 80 retain the binder in the machine.
