FLY-LE AFING MACHINE Specification of Letters Patent.

Patented April 13,, 1909.

To all whom it may concern.

Be it known that we, THOMAS A. RILEY and PETER F. HUGHES, citizens of the United States of America, and residents, respec tively, of Central Falls and Pawtucket, in the county of Providence and State of Rhode Island, have jointly invented certain new and useful Improvements in Fly-Leafing Machines, of which the following is a specification.

Our invention relates to novel improvements in machines for automatically ing fly-leaves or strips of paper to the interior of paper or paste-board boxes. The present fly-leafing machine, so-called, is, however, more particularly devised and adapted for automatically selecting, gluing and affixing a thin fly-leaf or strip of paper along the upper inner edge of one of the side walls or neck of boxes, the latter being suitably positioned on and removed from the machine singly and in an intermittent manner by an attendant.

To this end our invention consists, essentially, of an organized or self-contained ma chine having means for intermittingly coat ing a glue-bar, so-called, or wiper with an adhesive substance, as paste or glue, from a suitably disposed supply; means for holding a pad of loose fly-leaves with respect to said bar; means for supporting an inverted box in position above the bar and fly-leaves, and devices for transferring glue from the bar to the proximate surface of the box and pressing the latter against the positioned fly-leaves, the result being to evenly and smoothly aflix the adjacent leaf to the box, all as more fully hereinafter set forth and claimed.

By means of our invention fly-leaves may be secured to boxes in a more uniform and rapid manner than has-been possible heretofore; the workat the same time being effected with greater accuracy, sureness and cleanliness, the latter referring to the fact that the box is not liable to become accidentally spotted or smutched with the adhesive material used while it is being oper ated upon on the machine.

In the accompanying four sheets of drawings, Figure 1 represents a front or right end elevation of a selfcontained powerdriven fly-leafing machine embodying our invention, a portion being broken away adj acent the fly-leaf container or holder. The

are taken at right angles to the said inclined plane. Fig. 3 1s a transverse section taken substantially on line 3 3 of Fig. 2, and immediately preceding the gluing of the box. Fig. 4 is a similar sectional view showing the position of the mechanism while the glued surface of the box is being pressed against the adjacent fly-leaf of the pad. Fig. 5 represents a partial front end elevation, corresponding substantially with the position shown in Fig. 3. view, corresponding with Fig. 4:. Fig. 7 is a sectional view taken 011 line 7 7 of Fig. at. Fig. 8 is a longitudinal sectional view taken on line 8 8 of Fig. 2. Fig. 9 represents a perspective view of a box, and Fig. 10 a similar view showing the fly-leaf aflixed to the box.

In the drawings, 3. Fig. 1, indicates our improved fly-leafing machine as a whole. The operating mechanism proper is mounted on suitable legs a provided at the top with flanges a a, the latter extending rearwardly and upwardly at an angle say of 30. he front side of the base portion of the machine is extended to form the flat level work table 6 secured by bolts to said flanges (d; the rear portion of the base is inclined and bolted to the flanges a all as clearly shown.

At or near the back portion of the base are located a pair of laterally separated short standards 1 forming supports and bearings for the revoluble driving-shaft 8. See also Fig. 2. This latter has a pulley p secured to its front end a driving-belt 29 Between the latter and the front bearing the shaft is provided with a sprocket-wheel 11 carrying a chain of for transmitting power to a smaller wheel 21 fixed to the shaft 12 of the main glue-roll B which is revoluble in the glue or other suitable adhesive material contained in the reservoir G. See also Figs. 3 and 4. The shaft of said roll is mounted to revolve in hearings in the vertical sides Z) of the frame or hous- Fig. 6 is a similar adapted to receive to roll I) and later applied to the glue-bar and the neck of the box.

The following is a description of the means represented for controlling and effecting the lateral adjustment of said roll G: The two end portions of the rolls shaft pass freely through elongated openings 0 Fig. 3, and revolve in bearings formed in the free ends of members 12 in turn supported on pivots y fixed in the vertical sides of frame 6. A bolt y is jointed to each member y and extends rearwardly therefrom and through a fixed ear y; nuts y and 3 maintaining it in any desired position. As thus devised means are provided whereby the roll C may be set or adjusted in relation to roll B so as to readily and accurately vary the thickness of the glue carried by the latter, as desired.

The front side of the machine, that is at the point where the fly-leaves are affixed to the boxes, is provided with a longitudinally extending vertical pocket or recess R, open at the top, in which is removably mounted the vertically adjustable holder or reservoir E containing the pad or block of superimposed individual units or fly-leaves 2 supported edgewise therein. As drawn, each end of the holder is provided with a guide or rod 2 movable therewith and extending downwardly through the base Z2 (Figs. 4, 8, &c.), set-screws 2 maintaining the holder in the adjusted positions. The holder does not extend above the top face of the table 0, although the corresponding edges of the fly-leaves do; in fact the distance that the latter projects above the table practically determines the width of the surface that is to be glue-covered.

Immediately in front of and forming a support or backing for that portion of the fly-leaves extending above the table is located a removably secured bar n its length being equal to that of the leaves 2 and also being substantially flush with their upper edges. This bar should always correspond with the length of the leaves. These latter are maintained in position longitudinally or endwise by means of the two thin end gages F resting flatwise upon and being secured to the table a by the clamping bolts f passing through slotted openings f formed in the table. The rear ends of these gages extend transversely across the said pocket R and over the vertically movable yieldingly mounted glue-bar carrier member m, soon to be described; the top edge or face of the latter when in the normal elevated position being substantially level or even with that of table 0. The said member m is as shown comparatively Wide and is fitted to move vertically in recesses 6 formed in the two end members of the frame 5. See also Figs. 5 to 8. It is provided with a pair of vertical tie-rods 6 each having a helical spring 6 arranged to press the member m upwardly. The glue-bar n, above referred to, is substantially the same in form and size as the bar 01 It is secured to the top of carrier m and projects therefrom laterally a short distance toward the rear. To the rear side and near each end of member m is fixed a vertical cam-shaped projection 1'- disposed just outside and contiguous to the side frames 6,- these cams in cooperation with thetwo swinging arms 2' pivoted at i to said frame are adapted to contact with the lower end 2' of said arms and swing the upper portions of the latter a short distance toward the front whenever the member m is depressed to its limit. See Fig. 6. The object of this arrangement is to temporarily lock the freely revoluble transfer glue-roll D in position while the member m in its upward movement causes the face of the glue-bar n to contact with the surface of the roll and receive therefrom a thin coat of glue preliminary to gluing the next box. See Figs. 4 and 6. The roll D is journaled in said arms 2', its shaft 2" extending through elongated openings z' formed in the side frame. Springs 1 engaging the lower portion 2' of the arms operate to swing the roll rearwardly to contact with the surface of the continuously revolving main glue-roll B when the member an carries said cams upwardly past the" arms. See Fig. 5.

The upper portion of each side frame I) is provided with ears 6 having a horizontal guide-rod b" secured thereto. A cross-head (Z is mounted transversely of and slidable on said rods. The former extends transversely of the machine and is jointed at each end to a knee-lever f secured to a mechanically actuated rock-shaft g mounted in ears f depending from the base Z3 As thus arranged the guided cross-head reciprocates back and forth in one plane by means of the levers f, the ends of the latter being slotted to allow for the versed sine of the are through which the levers move. A presser-bar h is also slidably mounted on said rods o the same being arranged parallel with and located in front of the crosshead. The member 71. is resisted or pressed by helical springs cl interposed between the parts (Z and h. The latter is connected to and actuated by the cross-head through the medium of flat links 72. having slotted apertures 7L2 therethrough so as to provide for a degree of lateral movement independently of that imparted to it by the crosshead. The front or working side of the presser-bar may be provided with a longitudinally extending strip h of rubber or other material having a degree of elasticity and compressibility. See Figs. '2, 3 and 7 hen in action the said face of the bar it is adapted to engage the outer face of the neck portion a of the positioned inverted box H and press the latter toward the front until its inner surface bears snugly against the adjacent glue-coated surface of the gluebar 11 carried by the vertically movable plate member m. At or near each end of the latter is secured adog or lug m the same extending a short distance above the top face and normally above the plane of the lower side of the presser-bar. The face of the lugs are arranged and positioned with respect to the working face of said bar so that the latter will engage the lugs and not the glue-bar in case a box be omitted, thus positively preventing the glue-bar from contacting with and smearing the presserbar.

The mechanism for actuating the rockshaft 9 comprises a crank-disk is secured to the rear end of the main driving-shaft, a crank-pin s fixed to the disk at a proper distance from the center to give the desired stroke to the cross-head, a lever s fixed to shaft g, and a link 8 extending through an opening formed in base 72 jointed to said crank-pin and lever.

Assuming now that the several devices have been adjusted or positioned and prop erly timed with relation to one another, the reservoir G charged with glue or other suitable adhesive material, the pad of loose superimposed fiy-leaves or units 2 placed in the holder E and the gages F positioned close to the ends of the pad, and having the crosshead, &c., at the rear end of the stroke, or dead center, substantially as represented in Figs. 1, 2 and 3,'themanner of operation of described as follows: N ow upon starting the machine, see arrow direction Fig. 1, the revolving geared glue-rolls C and B operate to transfer a portion of the film of glue direct from the surface of the latter roll onto the laterally movable transfer-roll D then contacting therewith. \Vhile the cross-head is now advancing on its forward stroke the working face of the presser-bar it engages with and is arrested by the said end lugs m of the then normally elevated carrier member m, thus preventing actual contact with the glue-bar n, a box H not being in position. The continued forward movement of the cross-heads operating levers f, the shorter arms f of thelatter and the screwthreaded rods f jointed to the member m and. passing freely through the free ends of said arms, next operate to depress the member m, thereby at the same time causing the cams r our improved fiy-leafing machine may be l 1 l l l l thereof to swing the glue-transferring roll D away from the roll B to the forward tem porarily stationary and locked position, the further and final movement of the operating levers forcing the member at downwardly to its limit, thereby, too, at the same time carrying the lugs m below the bar It and wiping the working face of the gluebar it against the surface of the roll D. Fig. 3 represents the corresponding position of the parts. At the instant the bar h is thus released the springs (Z of the still advancing cross-head act to press the member 71. ahead to its limit. If the holder E is supplied with the fly-leavese the latter will arrest the bars movement, otherwise the bolts 7f passing through the slots if of the links h will constitute the stop. Upon the return stroke of the cross-head, &c., the springs c elevate the carrier on until its lugs m 'contact with the underside of the then rearwardly moving presser-bar, the glue-bar n at the same time again taking glue from the roll D. At the instant the bar it slides past the lugs m the springs 6 force the member m upwardly to its limit of movement, thereby withdrawing the cams 1' from the roll-carrying levers i and permitting the springs r to swing the roll D back to its normal position against the surface of the main roll B to be recharged with a film of glue, substantially as sh wn in Figs. 3 and 5. The operator now positions an inverted box H'upon the gages F of the table 0 so that the side wall portion of the neck a (to the inner face of which the fly-leaf is to be aflixed) will be interposed in the then open space formed between the adjacent faces of the presser-bar and glue-bar. See Fig. 3. The cross-head now in its advancing stroke causes the bar it to yieldingly engage the said neck portion of the box and press it bodily along until its inner surface bears evenly and firmly against the glue-covered face of the glue-bar 'n. Fig. 5 represents the corresponding position. The further movement of the rockshaft, &c., advances the roll D into position, depresses carrier member at, and causes the face of the bar a to slide downwardly past the neck of the box, thereby at the same time aviping off or transferring the glue from the bar onto the said inner surface of the contiguous neck portion of the box. At this instant the now released presser-bar immediately acts to push the box ahead bodily until it is arrested by the pad of flyleaves, the resilient force operating through the bar it causing the upper or, as drawn, the rearmost fly-leaf to become evenly and securely afiixed to the glued surface of the box. Figs. eland 6 represent the corresponding position. Meanwhile the member at completes its downwardstroke and is returning upwardly while the presser-bar is being retracted from actual contact with the box; at the same time too the glue-bar is being re-coated with a film of glue, as before described. At the completion of the operation the relation of the several parts will be substantially as shown in Figs. 1 and 2, the machine being in intermittingly continu ous action. The attendant now removes the box with its afiixed fly-leaf from the machine and places another box H in position as before, between the presser-bar and glue-bar, to be acted upon during the next revolu tion of the driving-shaft. It is obvious that as the pad of fiy-leaves in the holder E becomes gradually reduced in thickness during the flyleafing operation the presser-bar automatically adapts itself to such varia: tions by means of the springs (Z so that the efficiency of the machine is maintained at all times, even though a few or only one leaf be present in the holder.

' e may add that we prefer to make the length of the glue-bar a just equal to or slightly less than the length of the box interiorly, thus providing means for accurately positioning or centralizing the boxes. The front bar 11. is a little shorter than the gluebar, as indicated in Fig. 2. In order to preventthe bar n. from applying glue to the extreme corners of the box the vertical ends of the bar are cut away or beveled, substantially as shown in Fig. 2 at a In fact the leaves 2' are usually shorter than said bar, as shown in said figure.

In some cases it may be desirable to operate the machine manually or by treadlepower. In order to accomplish this we have shown in Fig. 1 means well adapted for the Thatis to say, the rock-shaft f/ has a lever 10 secured thereto to the free end of which latter is attached a cord or flexible connection 20 the same passing over a carrier wheel to mounted on a fixed stud 10* and finally attached to the rear or free end of a treadle-lever w fulcrumed at w to the legs (4. Upon depressing the treadle the cross-head will be advanced and the cooperating parts actuated substantially as before described. In order to return said members back to the normal position weights 16- may be attached to and suspended from the free end of lever s by means of a connec tion 11 clearly indicated by dotted lines in Fig. 1. It may be added that obviously when the machine is being run by belt power the said treadle and weight connections are first detached from the respective members to and 8 Conversely, the link a" should be disconnected from the crankpin s .hile the machine is being operated by foot power. If desired the shaft a may at the same time be rotated to drive the glue-rolls B and C.

In Fig. 1 we have represented the mechanism constituting the major part of our improved fly-leafing machine mounted at an angle or inclined to the plane of the floor.

I An advantage resulting from this arrange- I l f 1 i l l sures that it ment is that the fly-leaves z in the holder or container maintain themselves in proper position by gravity; that is to say, the overbalanced weight of the pad of leaves inwill lie at all times against the front side of the holder. e may further add that without departing from the spirit of our invention other means or modes of applying the principle of the invention may be used in lieu of those represented, provided of course that such substitute means employed be the equivalent of the means embodied in the subjoined claims.
