Toall whom 'it may concern: l

Be it known that l, CHARLES F. TAYLOR, a citizen of the United States, and resident of Hartford, inthe county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Binding Tablets, of which the following is a full,'clea'r, and exact specification.

This invention relates to tablet or pad machines, and more especially to that class thereof in which a number of sheets of gether by means of tape which at the same timesecures the top cover firmly to the back board wit-hout however interfering with the removal of the several .sheets of paper, which latter are usually first solidified at one edge by gelatin-gum and subsequently reinforced and covered by'tlie'tape above referred to, thus producing a book of stationery, the several leaves of which maybe readily pulled out, one by one, without' a'ffecting the covers. y

My invention has forits primary object the provision of a simple machine into which the tablets are consecutively fed, and the binding tapeI is properly pasted in place so as to secure the covers together.

My invention has, furthermore, for its object the provision of proper tape-guiding means whereby the tape' is positioned relatively tothe tablet so as to project over and adhere to the covers for the required 'distance.

A further object of the invention resides in the provision of improved tape-,pressing or ironing devices for producing smooth and uniform wol-inno matter whether the tablet be. thick or thin,` orwhether its edge is flat or wavy. My invention has,` furthermore, for its object the provision of a tape-gumming mechanism whichis automatic. in its action andl lays a film of gum or glue on the tape preparatory to the latters engagement with the tablets as they pass through the machine.

l Other objectsof the invention will hereinafter appear and beparticularly pointed out in the claims. l -1 ln-the accompanying drawings, in which similar characters denote similarparts, Figure 1 is a top view of tabletb1ndingmachine embodying my invention. Fig. l2 shows a front view thereof. Fig. 3 represents a longitudinal vertical section taken on line 3-3 of Fig.. 1. 4 is a vertical crosssection taken on line 4--4 of Fi 1, and Fig. 5 illustrates the manner in w ich the tape is applied to the tablets.

Briey'stated, the tablets -to be ta l d are .fed by the operator to a continuous movmg endless carrier-chain which is provided with a series of'tabletengagi'ng devices so disposed as to leave a small space between the rear edge of one tablet andthe front edge of the succeeding one in which condition the several successive tablets are carried between suitable guiding rollers into contact with the tape which has its inner face provided with a film of gumor glue and is pressed against the back ofthe tablet, as

well as laid over the edge of the top cover and back board thereof. The tape is pulled along by the. movement of the tablet to which it adheres, and the several succeeding tablets are thus bound in what may be termed a continuous manner, -so that the gaps, between the successive tablets 'are bridged by said tape, which latter may be cut by a suitable mechanism or by hand, in order to sever the several tablets. which are then discharged from the machine by the movement of the carrier chain.

Referring to the drawings, the numeral denotes a table having 4a smooth top and adapted to support the tablets which are placed thereon by tbe operator at O, so as to rest .with their back-edges against a series of vrollers 11, which are journaled on studs 12 fixed on frame lor bedisupport 13, extend ing the entire length of the machine and supported by legs 14. In order not to obscure some parts of thev machine-mechanism, the tablets T', T2, T3 on thev table in Fig. 1 are indicated by dot and dash lines, While in the other figures they are shown in full.

Disposed at the left hand end of the-machine, is a shaft 15 jonrnaled in bearings 16,.

17, and supporting 4a -loose pulley 18 which may be clutched to the shaft by a collar 19 under the control ofthe operator by means of a longitudinally-'disposed shipper shaftjournaled in bearings21, 22 and provided with handles 23. Secured to the. shaft 15, is asprocket wheel 24 for drivingachain 25 which constitutes the tablet-carrier of the .machine and the upper run of which is supthence around an idler 31 cna shaft 3 2 jcurl naled in bearings 33, 34 disposed at the right hand end of the machine. Secured at certain predetermined points of the chain are a series of tablet-engaging devices or pushers 35, the distance between which may be varied as desired and' to correspond to the length of the tablets to be o erated upon. In the present instance, the ength of the chain is such as to provide for seven distance-s aces, and it. will be understood that -if the c ain be shortened or lengthened to accommodate either a less number of greater spaces, or a greater number of smaller spaces, the idlers 27, 28, will permit this action and keep the cha-in tight.

Each tablet, as it is placed on the table by the operator is successively engaged at its rear or right hand end by the first pusher coming into action, and is then caused to roll of t-ape R is sup Orted on uprights 45 which form a part o a frame 46 carrying a tank 47 which contains glue or similar adhesive. Under ordinary circi'imstances I consider. glue to be best suited for the present needs, and means are provided for maintaining said glue in soft and plastic condi-- tions, these means consisting substantially of a heat'chamber arranged below the gluecompartment of the tank 47 and adapted to be kept hot by the introduction of steam entering the same through a steam-supply pipe 48, a pipe 49 being provided to carry off cony:sa

ensation in said chamber. From the supply roll R, the tape t isconducted over a roller 50, then around a gravitative loopingroller 51 whereby the roll is unwound as needed, andbetween the jaws of a stationary. tension device 52, whence the tape passes into peripheral vcontact with a guinm-ing roller 53 which is journaled on the frame 46 and transfers the glue in the tank 47 to the underside of the tape t.

.From the gum-roller 53, the tape passes over idlers 54, 55, and is then given a quartter turn so that its width will-now be disposed vertically,.in which condition it passes over and partially around the' roller 40 previously mentioned, and into contact withthe back-edge of the tablet.l v

The Width ofthe tape is generally about from one half inch to one inch greaterlthan the thickness of the tablets to be bound'so that the tape edges can lay-over the tablet sufficiently to take a firin hold on both the to -cover and the bottomboard, and, in or er to insure a pro er guiding of the tape so that such overay may be alike on top and bottom, or at least to prevent any variation from the parallelism of the tape edge with the tabletl edge, I deem it expedient to pass the tape between' a pair of guide-fingers G0, (il disposed adjacent the tape roll 40 and mounted for adjustment vertically on a stud 62 which is secured to the frame 13. In this manner the line of tape-travel is positively positioned relatively to the back-edge of the tablet, and the amount of over-lay can be regulated as desired.

. In order to assist the tape-guiding devices, I provide means for holding the tablet against the table, a feature which becomes necessary in practice on account of the natural tendency of the tablet to rise and also on account of the vertical undulations of the backedge. In the present instance I have shown for this purpose a presserblade (35 preferably mounted atone end on a horizontally disposed spindle, 6G, journaled in a bea-ring 67 and having an arm G8 which is pulled downward by a spring' 69, so that the blade 65 normally tends to hold the backedge of the tablet down, and yet may be thrown upward and out of the way when-desi-red. Furthermore, the construction will permit the blade to accommodate itself to different thicknesses of tablets without requiring any special adjustment.

Inasmuch as under the conditions above described, the edges of the tape will project above and below. the limits of the back-edge of the tablet, mea-ns are provided to turn both tape-edges over the tablet, subsequent to the adhesion of its main or body portion therewith, which latter result is achieved by employment of a flattening roller 70 mounted on a'spring-actuated frame 71, pivotally supported on the stud of the roller 40. By virtue of'this organization, any variations from a straight-line travel of the back edge of the tablet cannot influence the proper operation of the roller 70.

The function of turning-over the edgeportions of the tape, may be performed in many different ways, and experience has shown that a common stiff-bristle brush, such-as is shown at- 72 in Fig. 1 will answer the intendedpurpose as well as if not better than, any other, the bristles naturally touching every portion of the tape and therefore producing a. full-surface contact between tape and tablet. The brush 72 is also mounted for adjustment relative to the tablet-travel, by being secured upon a vertical arm 73 of 'a holder 74 which is clamped to a spring-actuated block-7 5 swiveled in a rod 76 and tending to force said brush' toward the tablet, its inward movement being limited by a stop 77. After passing the brush at 85 on an ear projecting l successivelyand i' 87 is gravitative. and

i justable 7 2, the tape is edge-rolled by a' combination roller comprising in its preferred form three independent elements, viz. a back-edge roller 80, a top stretcher 81, and a bottom stretcher 82 (see Fig. 3), all of Which are mounted for free rotation spring-actuated frame 811 Whichis pivoted from the frame 13. Of these, the roller 80 serves to roll the back-edge While the stretchers by virtue of their initial inward rotation tend to stretch the tape edges, and by the Weight of the, top roller S1 press the stretched edges into close contact with the tablet. From the combination roller, the tablets are carried past a stationary guide roller SG and between a air of what may be termed ironing rollers 87, 88, which flatten the turned-over portions of the tape aga-inst the tablet, and the lower one, 88, of which maybe frictionally driven by a belt 89 connecting the pulley 90 on the roll-shaft 91, with a driving pulley 92 secured on the main power shaft 15 previously mentionedl The upper roller rests on top ot the tablet. After passing the. ironing rollers 87, 88, the taped tablet-edge is again subjected to the naled on a stud 91 carried by a springactuated swinging frame 95 pivoted at 96 on the frame 13. l

From the foregoing it Will be understood, by recapitulation, that the tape is rst positioned relatively to the tablet, then edgedvover by the brush, then stretched, then ironed on top and bottom and finally backrolled, the several operations taking place rapidly While t-he gum or glue is setting.

-The several elements `inst enumerated cooperate Witli the preset-device P which engages the tablet at its front edge, and, inasmuch as more or less unevenness exists in such edge, the presser device is slightly resilient, as is illustrated in Fig. 1, in which the rollers l11, -lfQ are shown mounted in a bar 100 which is movably held under adspring-pressure relatively to a stationary holder 101 adapted to be adjusted transversely of the table 10, to accommodate tablets of different widths, by thumbscrews 102 in enga gement with suitablc'nuts' shiftable in slots 103 provided in the table 10. A spring-blade 104: issecured to the stationary the front edge of the tablet from rising under the lateral pressure of the tape-manipulating device at the other edge of the tablet,

on a stud 83 held in aaction of a back-roller 93 jour holder 101 and serves to prevent` While at the same time such vblade will operate on tablets of different thicknesses and its tension will increase in proportion to such thickness. After passing the tape-applying devices, the tablets will be guided by a roller 105 to and between a pair ot finishing rollers 106, 107 (see Fig. the loiver 107 is stationary, While the upper is mounted orrotation on a comparatively heavy slide 108 guided on pins 109 attached to a bracket which is secured to the frame 13. The tablets being noW taped, Will be discharged by the movement of the carrier chain 25, it being understood, of course, that the tape portions which connect the several tablets in the manner indicated by C in Figs, 2, 3 and 5, are cut, either by automatic mechanism, or by another attendant who can take Careof replenishing the tape-supply and its introduction into the machine at the rear of the table, at theI same time.

In conclusion it should be noted that the body portions of the several vertical rollers extend slightly below the top level of the table so that a proper engagement between said rollers and the respective tablet-edges will always be assured.

vMany changes may be made in the general organization ot' the several coperative elements, or in their particular construction, without departing from thespirit ot' the invention.

I claim: 1. The combination, with a table, and means for feeding tablets successively over said table, of means for applying tape to one edge of the tablets, a movable bar operative onthe other edge of the tablets for guiding said tablets into contact with the tape-applying means, a stationary member on the table, and springs interposed between said bar and member; 2. The combination, ivith a table, and means for feeding a tablet over said table, of means for app ying tape to one edge of the tablet, a yielding presser bar operative on the other edge of the tablet for pressing the same into contact with the tape-applying means. means for varying the pressure of said yielding member, and a pair of independent. spring-actuated devices for maintaining the opposite edges of the tablet in contact with the table top.
