WALTER L. J ACOBIE, OF GLENS FALLS, NEW YORK.

BACKlNG-STRlP-APPLYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,657, dated May 3, 1904.

Application filed February 4, 1903. Serial No. 141,927. (No model.)

To all whom, it may concern:

Be it known that I, WALTER L. J AOOBIE, a citizen of the United States, residing at Glens Falls, in the county of Warren and State of New York, have invented a new and useful Backing-Strip-Applying Machine, of which the following is a specification.

The object of the present invention is to provide a mechanism for placing backing-strips on books, tablets, and the like in order to hold the signatures, leaves, or sheets together.

A further object of the invention is to provide a machine in which a continuous strip of backing material is provided on one surface with an adhesive, such as glue, and is placed in position against the backs of the books or other articles and the strip severed at points between successive books to which it is attached.

A still. further object of the invention is to provide a mechanism which may be readily adjusted to accommodate books of any size and in which provision is made for pressing the strip into position with any required degree of force in accordance with the character of the Work.

With these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size,' and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of a backing-machine constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a sectional plan view of a machine on the line 3 3 of Fig. 1. Fig. 1 is a detail perspective view-of the strip-cutting. mechanism detached from the machine. Figs. 5 and 6 are transverse sectional elevations of the strip-guides on the lines 5 5 and 6 6, respectively, of Fig. 2.- Fig. 7 is a detail view showing the connections of the pedal-lever.

5 7 Similarcharactersof reference are employed to indicate corresponding parts throughout the several figures of the drawings. The various operating parts of the mechanism are supported by a frame 10, having standards of suitable height to support the machine at a convenient distance above the floor, or the standards may be omitted and the upper bed-plate 11 of the machine mount+ ed on a suitable table or similar support.

Supported above the base-plate are two similarly- shaped frames 12 and 13, the frame 12 being mounted on spaced standards or posts 15, secured rigidly to the bed-plate, while the frame 13 is mounted on similar standards 15, secured to spaced plates 16, these plates being adapted to guideways 17, carried by the bedplate, so that the frame 13 is free to move toward and from the frame 12. The frame 12 comprises a lower plate 12, astandard 12, and an upper plate 12", while the frame 13 comprises similar members 13, 13, and 13", respectively. The frame 13 is pivotally connected to one arm of a bell-crank lever 18, mounted on the main frame and having its opposite arm connected by a link or rod to a suitabletreadle-lever 20, placed within convenient reach of the operator, so that by operatingthe treadle the frame 13 may be moved toward the frame 12, the force exerted being dependent on the character of the work. Each frame 12 and 13 is provided with upper and lower bearings for the support of spaced spindles 22, having their axes in substantially vertical planes and parallel with each other. These spindles carry work-guiding rollers 23, which may be covered with cloth, felt, rubher, or other suitable material to prevent injuryto the books or other articles passed between them during the operation of the machine.

' To the horizontal plate 12' of the frame 12 is secured a pair of adjustable bars or strips 25, preferably provided with longitudinal slots 26, through which pass clamping-bolts 27 in order to permit the locking of the bars or strips in any desired position. The inner ends of these bars are provided with upwardlyextending members, to which is secured a strip guiding and supporting bar 28., mounted at a suitable angle to the horizontal, this bar surv- IOO ing as a guide and support for the strip of backing material on the books or other articles to which the backing-strip is to be secured. As the guiding-rollers 23 are arranged in substantially vertical planes, they tend by contact with the sides of the book traveling upwardly on the inclined bar 28 to press the books downwardly. and hold the backs thereof firmly in contact with the strip of backing material.

The vertical bar of each of the frames 12 and 13 is provided with an opening for the reception of a longitudinally-adjustable bar 30, having at its outer end a clamping-screw 31. The inner end of said bar is bifurcated and forms a bearing for the support of a small spindle 32, arranged at a slight angle to the vertical and on which is mounted a guidingroller 33. The plane of the axes of these two rollers is approximately at a right angle to the inclined plane of the bar 28, and the rollers merely assist in holding the book or other article in position without exerting any downward pressure thereon.

At points below the bars 30 are adjustable bars 361, having locking-screws 35 and bifurcated at their inner ends to form supports for spindles 36, on which are mounted rollers 37 for engagement with the opposite sides of the strip of backing. material which is being applied to the books. In connection with this portion of the mechanism it is to be noted that the angle of the axis of the spindle 36 with respect to the plane of the bar 28 is less than a right angle, so that as the roller 37 engages with the edges of the backing-strip they will tend to exert an upward drawing or pulling movement on the opposite sides of the strip in order to stretch the strip over the back of the book in practically the same manner that this operation is now accomplished by hand, and while this has the tendency to raise the book any upward movement of the latter is prevented by the greater force in downward direction exerted by the rollers 23. The bar 28 is provided with an inclined recess 38 at a point directl y between the opposite strip-engaging rollers in order that said rollers may be adjusted inward beyond the opposite edges of the bar in accordance with the thickness of the books or other articles, as well as to permit inward movement of the frame 13 under pressure from the treadle.

The several roller-supporting bars 30 and 34 are projected inwardly against the book by means of coiled eompression-springs 40, surrounding each of the bars and disposed in recesses in the vertical members of the frames 12 and 13. y

The lower ends of the vertical spindles or l shafts 22 extend through the horizontal members 12 and 13 of the frames and are provided with pinions 11, the two pinions on each frame being conuectcd by an idler-gear 42, and movement is lmparted to one of the pinions on the stationary frame 12 by means of gears 13 and 44, the latter being secured to the upper end of a vertically-disposed drivingshaft 45, having a belt-pulley 46, driven from any suitable source of power. The two gears t3 and 44 are supported by a bracket 49, which may form a part of frame 12, and in order to impart the necessary driving movement to the feed-rollers of the movable frame 13 without interfering with the adjustment of the latter I employ a connecting-gear 51, inter-meshing with the geart3 and with one of the pi nions 41 of the movable frame. The connecting-gear is mounted on a pin '52, carried by a yoke 53, which is supported at one end of a spring-arm 54, carried by the bracket 49, the arm always keeping the gears in mesh regardless of the extent of movement of the frame 13.

Ata convenient point under the frame of the machine is a receptacle for an adhesive material, glue being preferably employed, and a suitable heater 61 being placed below the receptacle in order to keep the glue in proper condition for application to the backing-strip. The opposite sides of the receptacle 60 are provided with bearings for the reception of the ends of a roller or drum 62, dipping into the adhesive material and adapted to apply the same to one surface of a strip 00, of backing material, which is drawn from the reel 63, mounted at one side of the frame. This strip may be formed of textile or any other flexible material and may be of any width in accordance with the character and size of the work. After passing from the glue-supplying roller the coated strip is conducted forwardly under the end of a bar 65, extending from the frame of the machine substantially in alinement with the bar 28, and at the outer end of said bar 65 are brackets 66 for the support of a roller 67, which makes contact with the uncoated surface of the strip and turns the coated side uppermost in proper position to receive the books. The strip is conducted between a pair of folding-guides 68, comprising substantially vertical arms or plates having downwardly and inwardly bent upper ends 69 and serving to bend the strip in approximately U-shaped form in order that it may be properly applied to the backs of the books or other articles. The folding-plates are provided with horizontal bars which pass under the bar 28 and are slotted for the passage of a locking-screw 7 O, by which they may be held in adjusted position. The slots permit of the adjustment of the holders to any desired distance from each other in accord ance with the width of the strip to be applied.

At a point between the folders and a pair of guiding and feeding rollers 23 is arranged a pair of guiding and pressing plates 71, having their rear ends clamped under the bar 28, while their forward ends, or those ends nearest the feed-rollers, extend over the top of the bar 28 and engage the opposite sides of the properly guide the books into contact with the adhesive surface of the backing-strip without the exercise of any particular care on the part of the operator.

At one side of the stationary frame 12 are bearings for the support of ashaft 76, disposed in a plane parallel with the strip-supporting bar 28. One end of the shaft is of rectangular or other suitable form, as indicated at 77, and passes through a similarlyshaped opening in a sleeve 78, the sleeve being of cylindrical form and adapted to one of the bearings, suitable means being provided for preventing longitudinal movement of said sleeve. On the sleeve is mounted a grooved pulley which may be driven by the belt from any suitable source of power. The opposite end of the shaft extends through an elongated sleeve and is provided at its outer end with a grooved pulley 81. The outer end of the sleeve is rigidly secured to a rocker-arm 82, provided at its free end with a bearing for the reception of a spindle 84:, on which is mounted a grooved pulley 85, driven by a belt-wheel over the pulley 81. This spindle also carries a disk 86, the periphery of which is arranged to form a series of alternating teeth and notches somewhat after the manner of a saw, but forming, in effect, a sharp cutting-knife having a serrated edge, the cutter-disk being adapted to sever the strip of backing material at the end of each book. On the sleeve is pivoted an arm 88, having a vertically-disposed finger 87.. The upper end of the arm 88 has asmall roller 89, which normally lies in the path of movement of a book or other article passing over the feed-rollers, so that the end of the book will engage said roller or arm and move the latter, together with the arm 82, the sleeve, the cutter-disk, and the pulleys outwardly withthe book, and it will be observed that the upper or book-engaging end of the arm 88 is in the same vertical plane with the cutter-disk 86. In some cases the roller 89 may be dispensed with and the end of the arm 88 engage with the end of the books or ,other articles being operated upon. The inner end of the elongated sleeve is provided with an arm 90, adapted to ride over a cam 91, forming an inclined plane, the upper end of said cam 91 being pivoted at the top of a verticallydisposed post 92 and its lower end normally resting flush with the bed-plate 11, so that as the sleeve moves outwardly by the engagement of a book with the arm 88 the arm will ride up over the inclined plane and elfect an upward movement of the cutter-disk to cut the backing-strip at a point directly under the arm 88 and close to the advancing edge of the book. The outward movement of'the sleeve, the cutter, and other connected members takes place against the resistance offered by a spring 93, and as soon as the arm 89 is disengaged from the forward end of the book said spring will act to return the parts to the initial position in readiness for a subsequent ope-ration.

Near the rear side of the bed-plate is a bracket 95, to which is pivoted a two-armed lever 96, one end of which normally rests at a point directly under the upper end of the inclinedcam 91, while the outer end of the opposite arm is provided with a finger 97, adapted to engage with the lower end of the arm 87 when elevated. As the arm 90, carr-ied by the sleeve, travels over the inclined cam 91 the cutting operation is performed, and when the end of the inclined cam is reached the arm falls into contact with the inner end of the lever 96, forcing the outer end of said lever upwardly until its finger 97 engages the lower end of the arm or member 87 and throws the arm 88 up, the end 89 of said arm being disengaged from the end of the book and the spring serving to immediately return the parts to initial position. During the return movement the arm 90 passes under the inclined cam 91, the latter swinging on its pivot to allow said arm to return to the initial position, while the book-engaging arm 88 lies against the side of the book and after passing the end of the latter again falls into the path of movement of another book being discharged between the rollers 23.

In order to prevent the feeding of books so close to each other as to prevent the proper operation of the cutting-disk without danger of injury to the books, I employ the spacingfinger 98', carried by a sleeve 99 on a rod 100, secured to one of the book-guides 7 2. Between the end of the sleeve and the extreme outer end of the rod 100 is a coiled compressionspring 101, which engages against a fixed sleeve or pin at the outer end of the rod'and serves to resist the movement of the sleeve and the spacing-finger. The finger normally lies at a point slightly in advance of the book guide and in the pathof movement of the books IIS any material to books, pamphlets, tablets, or other articles of any size.' In operation the coated strip is supported by the bar 28 and the books are placed one by one between the guides 72 and fed between the rollers 23. As soon as the rollers 23 engage the edges of the book they start to feed the same toward the discharge end of the machine, and by reason of their vertical position force the backof the book downwardly against the inclined member and into intimate contact with the strip of backing material. When the strip, having been properly folded and then pressed into initial engagement with the back of the book by the plates 71, arrives at the drawing and pressing rollers 37, said rollers force the strip firmly into contact with the opposite sides of the book, and by reason of the angle at which they are placed serve to draw the opposite sides of the strip upwardly, slightly stretching and smoothing the strip and applying the same in an even and regular manner to the back of the book. The upward tendency of the rollers 37 is effective only in so far as the strip is concerned, the superior area of the vertical rollers 23 preventing any upward movement of the book and holding the same firmly down, so that the backing-strip will be pressed into contact with all portions of the back of the book. The books may be fed successively through the machine, and by exerting greater or less pressure on the treadle the operator may press the strip more or less firmly into contact with the sides of the book, in accordance with the character of the work required. After passing from the discharge end of the machine the strips are severed at points between the books. The arm 89, which normally lies in the path of movement of the book issuing from the machine, is engaged by the book and moves therewith, causing an upward movement of the arm 90 over the inclined plane 91 and resulting in a similar upward movement of the cutter-disk into engagement with the backing-strip. At the completion of the cutting operation the arm 90 falls into contact with the lever 96, and the outer end thereof by raising the arm 89 releases the latter from engagement with the end of the book and permits the spring to return the parts to initial position in readiness to engage a second or following book.

While the machine has been described as employed for the backing of books, tablets, and the like, it is obvious that it may also be employed for the application of strips of ornamental paper and other material to the edges of cigar-boxes or to strips of paper-board or the like to be used in the manufacture of paper boxes.
