Figure 4 an enlarged fragmentary delta il .viev v;showing-v certain -.detai1sof the index g means: for f-the: bindingl welements;not shqw'szn e As shown on the drawings:
A binding machine I is shown in Figures 1 and 2 as comprising a casing ll having an inclined table I2 at the forward end thereof on which the sheets to be bound are placed for impaling on the upright ends I3|3 of the spread rings [4-14 of a binding element l5. 7
The binding elements l5-l5 may be made from sheets of thermo-plastic material, preferably of a non-explosive and slow burning type, and as shown in Figures 1 and 2 have a backbone portion I6 extending along the outside of the bound volume at the back thereof, with the spaced rings I4-l4 extending therefrom.
The binding machine H] has a plurality of laterally spaced fingers l9-l9 extending upwardly from the table 12 and adapted to engage the backbone l6 of the binding element between the, rings l4-I4 thereof and to hold the backbone in an upright position, so the rings may be uncurled or spread with the ends l3l3 extending upwardly from the table [2, to receive the sheets of paper to be bound. When the backbone holding fingers I 9-49 are in engagement withthe backbone of the binding element, with the rings thereof extending forwardly of said fingers, the backbone holding fingers are moved transversely of the table [2 to move the rings I l-I4 into engagement with the transversely extending ends of spreading fingers 29. The spreading fingers are movable longitudinally of the table, to uncurl or open the rings, with the backbone thereof held in an upright position by the backbone holding'fingers l9|9.
The binding machine 10 may be of any well known form and is herein shown as being of a type somewhat similar to that shown and described in a prior application Serial No. 773,578, filed by me on March 10 1947, so is only herein shown and described insofar as is necessary to make my present invention readily understandable. A backbone holding element 2| from which theupright fingers l9l 9 extend is herein shown as extending upwardly from and being mounted on a transversely movable bar 22 suitably guided beneath the top of the table l2 for transverse movement with respect thereto. The bar 22 and fingers I9I9 are moved transversely of the table 12 to position the rings for engagement with" the transversely extending ends, of the spreading fingers 20-20 by means of a spring (not'show'n) acting against a cam 23 formed on one face of a sector 24. The sector'24 is'freely mounted on a transverse shaft 25 suitably journaled in opposite side wall 26-46 of the casing H.
The spreading fingers 20-20 may be mounted on" andrproject angularly upwardly and rearwardly from a longitudinally movable member 21 slidably guided on laterally spaced transverse shafts 2828 spaced beneath the top of the table I2 and extending longitudinally thereof in parallel relation with respect thereto. A link 29 is pivoted to the sector 24 at one of it ends and has a'slot 30 at its opposite end, engaging a pin or bolt 3| extending from a lug 3|, depending from the member 21. The slot 30 in the link 29 i provided to delay longitudinal movement of the spreading fingers 2020 until the cam 23 has moved into position to allow the backbone holding fingers l9l9 to move laterally and move the binding element into position' to come into engagement with the transversely-extending ends of said spreading fingers. Another link 33 pivoted to the sector 2401 provided to move said sector about the axi of the shaft 25. Said link may be operated by a suit able system of levers (not shown), either operated manually or by power. Said operating means is not herein shown or described since it is no part of my present invention.
Spaced above and rearwardly of the table 12 and extending in the same angular direction as said table is a feeding plate34 along which the binding elements are adapted to move and drop therefrom one at a time into position to engage the fingers I9l3 and index themselves therebetween for spreading. The feeding plate 34 is l mounted on the] top of the casing II, or may be a part thereof, and is shown as having a blank receiving hopper 35 extendin across it upper or receiving end and'forming a magazine feeder for the binding elements l5-i5. The hopper 35 has a rear wall 36 herein shown as extending vertically of the feeding plate 34 and a front wall 31 extending parallel thereto with its lower end spaced above said feeding plate to allow the bonding elements to pass thereby. The front wall 31, as herein shown, has a plate 38 mounted thereon for vertical adjustment with respect thereto, in accordance with the diameter of the binding elements being spread, to allow one row of binding elements only to move down.- wardly along the feeding plate 34. The plate 38- is held in its various desired positions of adjustment by bolts and wing nuts indicated generally by reference characters 40-40 and extending through vertical slots 4 l"-4l in the wall 31; The blank receiving hopper 34 also has one fixed side wall 42 with a side guide plate 43 extending-forwardly therefrom, forwardly of said hopper, to form a guide for one side of the binding element. It also has an opposite side wall 44 slidably mounted between the rear and front walls of said hopper for adjustable movement therealong to take care of various lengths of binding elements. The wall 44 is adjustable along slots 45-45 extending along the front and rear wall 31 and 36 and is held in fixed relation with respect thereto on bolts and wing nuts indicated by reference characters 46-46. Aside guide plate 53 is shown'as extending forwardly of the'adjustable side Wall 44, and with the side guide plate 43 forms an adjustable guide for the ends of the binding element as they leave the hopper 35-and pass downwardly along the feeding plate 34,. The side guide plate 53 has a vertical slot 54 formed therein to receive the plate 38 when adjusted for smaller binding elements than those shown in the drawings. l
Extending across the'forward ends of the guide plates 43 and 53 is a vertically movable bar 55 governing the binding elements l4 leaving the hopper 35, and herein called a stop and go bar for convenience. The stop and go bar 55 has opposite inwardly turned end portions 5656 extending rearwardly therefrom and depending therefrom from which extend arms 51'51 herein shown as being continuations thereof and extending rearwardly therefrom to a point adjacent the rear end of the casing H. The arms 51-57 have upwardly extending rear end portions 58-58 pivotally mounted attheir upper ends on-sleeves 5959 mounted on a transverse shaft 60 The transverse shaft 60 is mounted at its opposite ends in angularly extending slots 6l6l formed inopposite side Walls 26-26 of the casing H in parallel relation with respect, to the feed-plate. The slots 6l6l afford. a means for adjusting the stonlend so her 5 .withlrespectrto a transverse indexing roller 83 with respect to the backbone holding fingers 19-19. V
The pins 95-05 are so positioned with relation to the supporting surface of the gap closing plate 9 1; and its axis of pivotal connection to the indexing roller 93 and also with respect to theaxis. of pivotal movement of thelinks- 84-84 that the gap between the discharge, end ofthe feeding plate 34 orthe, forward end of the stop and drop bar 65 will always be closed to anextent suffi cient to prevent a binding element 15 of the requiz-ed size from dropping in the space thereb'etweenin, all-positions of the indexing roller 83 with respect to the backbone holding fingers 19-19.
A motor '1, which maybe a fractional horse power electric motor having a speed reducer in corporated therein, is herein shown as being provided to drivethe indexing roller 83 by means of a yieldable belt 99 in the form of a closed tension;
spring having suificient tension to rotatably drive the indexing roller-83 in all positions of adjustment thereof with respect to the motor 91.;
It may be seen from the foregoing that as the stop and drop bar 65 is moved downwardly to a position so that its top is on a level with the top of the plate 3411, the binding element 15 may drop from the end of said'plate along the more steeplyinclined gap closing plate 91 into engagement with the indexing roller 83 and against the The index backbone holding fingers 19-19. ing roller 83' rotating at a relatively slow speed will then rotate the binding element 15 against the backbone holding fingers 19-19. into position for the rings of the binding element to pass between said fingers, regardless of .the position or. of the relation of thebackbone of the binding elementwithrespect to said backbone holding fingers, as it is discharged fromthe end of the plate 34.. The binding element 15 -is thus compelled by virtue of its rotatable moveme'ntim parted ;by the indexing roller 83 to change its position almost instantaneously as it comes into contact with said rollerand to properly index itselfwith respect to the backbone holdingv fingers 10-19 with its rings between and beyond said a backbone holding, fingers and with its backbone in engagement therewith, ready for the spread 'ing'cycle. V o It may be seenfrom Figure 2 that when plate;
and the guide 5 3 are properlyadjusted to the required width of the desiredbindingelement to beIspread and the stop and go and. the stopand d op. ar a the e n erit a pro e ly'setffor the diameter of the binding elementto be spread, that the hopper 34 may then be loaded with a' plurality of binding elements, as shown.
Upon depression of the lever 8 0, thesitop andv go bar 55 and the stop and drop bar 65 will bo th move downwardly with one bindingfe'lement.
dwelling'temporarily betweenrthe two bars, the
stop and go bar preventing additional binding elements from sliding beyond it. At thelend of downwardj'travel of said, bars, the binding ele ment dwelling between the two bars will fallf orslide down the gap closing'pl'ate 9 1 vonto the re; tatable indexing roller 83 against thebackbbne' holding fingers 10-19 of the working head of the:
indexing machine. Th'e'hand may then be 'renioved from the lever 80. h The springs 10-10; and '11-'11 will raise thestop and'go 'ana'sto'p and drop bars; to the positions shown -i n"Figu're 2, allowing another binding element to move;
downwardly along the feeding plate "34 and rest against-the stopand drop bar 65. -Thebinding element resting on therotating indexing .roller 83 against the backbone holding fingers 10-1-19 will then be rotated into position for the rings" thereof to extend between said fingers and said fingers coming into engagement with the inside of the backbone tohold the binding element in;
position for spreading. At this time the sector 24 and cam 23 may be turned in a clockwise direction by operation of the link 33. This will caliselateral movement of the backbone holdin fingers 19-19 with respecttoflthe plate 12 and will bring the insides of the rings 14-14 into position to'be engaged by the laterally turned ends Continued movement of said sector will move the spreading of I the spreading fingers 20-20.
fingers 20-20 longitudinally along the plate [2 to unc'url or spread the rings with the upright inner ends 16-10 thereof extending upwardly fromv the plate 12 for the insertion of the sheets ,1
to be boundthereon. V
Adjustableside guides for the binding elements may be removably mounted on the fingers 19-19 or may be adjustably mounted on the gap closing plate 91. i As herein shown upright guides.
101-101 are adjustably mounted on the plate 91. and extend upwardly and forwardly therefrom toward the fingers 19-19. Said guides are shown as having slotted bases 102-102 extending outwardly therefrom and held in position by wing nuts 103-103.
It will be understood that modifications an variations may be effected without departing from the scope and novel concepts of the present invention. a V
