BOOK-EDGE-PRIN'I'ING MACHINE.

Application filed May 11, 1925. Serial No. 29,480.

This invention relates to printing presses and more especially to machines for printing advertising or other matter on the free edges or ends of the leaves of a book and the object is to produce a machine capable of efiiciently producing impressions on the edges of books as rapidly as the books can be fed by hand or Otherwise to the machine.

A further object is to produce a machine which automatically accommodates itself to books of varying width and thickness, and a 7 still further object is to produce a machine of this character which is of simple, strong,

tion. 7

With these general/objects in view, the invention consists in certain novel and useful features of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is a plan view of a machine embodying the invention; Figure 2 is a side view ofthe machine. Figure 3 is a Vertical longitudinal section on the line IIIIII of Figure 1;

Figure 4 is a horizontal section on the line IVIV of Figure 3, with certain parts of the last-named figure omitted;

Figure 5 is an enlarged central cross sec- 1 tion with certain parts at one side omitted;

Figure 6 is a horizontal section on the line VI-VI of Figure 5; and

Figure 7 is a fragmentary vertical section on the line VII-VII of. Figure 2;

Referring to the drawings in detail where like reference characters identify correvsponding parts, 1 indicates parallel sides secured to legs 2 and 3, and connected at one end by a cross brace l and the legs are connected by longitudinalbraces 4 supporting a platform or shelf 4*. The sides are connected about midway their length by a cross piece 5. Projecting upward from the sides at the opposite side of cross piece 5 from the legs 3, are uprights 6, connected to the legs 3 at corresponding sides by the longitudinal bars 7, the parts thus far enumerated constituting a skeleton framework for the operating parts of themachine- Journaled in bearings '8 on the sides 1 between the parts 3 and 6 of the framework, is a transverse shaft 9 for abed roller 10 for cooperative actionwith overlying durable, compact and economical construcably supported shaft 16, and said shaft has a smaller pulley 17 connected by a belt 18 to a pulley 19 on shaft 9. The latter also has a pulley 20 connected by a belt 21 to a pulley 22 on a transverse shaft 23 journaled on the framework near legs 2 thereof. Said shaft also has a second pulley 24 connected by a crossed belt 25 to a pulley 26 on the shaft 27 of the roller 11, the power transmitting mechanism described thus providing for proper cooperative operation between rollers 10 and 11. i

The shaft of roller 11 is journaled in bearings 28 having upwardly-projecting vertically-slotted arms 29 slidably fitting plates 30 and resistance bolts 31 extending through the said plates into the bars 7, and thrust-bolts32 extend through the upper ends of the arms 29 and bear-upon the resistante bolts, so that the roller 11 may be vertically adjusted to impose its weight on books of predetermined thickness and yet be capable of moving upward to provide for the shaft of roller 35 for conveyer-tighten ing purposes, is journaled in bearings 36 having slotted arms engaged by screws 37 for guiding and clamping purposes. To adjustthe conveyer, thrust-screws 3 8 bear against the bearings 36 and are mounted in brackets 39 secured to sides. 1. As a means for taking slack out of the conveyer, its lower portion is engaged by a roller 40 having its shaft 41 journaled in plates 42 pro-' vided with threaded lugs 43 extending through vertical slots 44 in legs 3 and engaged by nuts 45 for clamping the plates 42 at the desired point on the said legs.

To prevent sagging of the upper part of the conveyer between the roller 10 and rollers and 35, a sectional table is employed, consisting of like members'46 secured on cross-pieces 47 fastened on. the

In order that the passage of a book between rollers and 11 may be insured, the roller 11 is engaged by one or more friction belts 48 which also engage a roller or rollers 49 of such proportion and so supported that the lower part of the belt (or belts) shall converge with respect to conveyer 34, toward the rollers 10 and ll. The rollers 'e9two being shown-are journaled in forked heads of bolts 50, extending through a transverse rocker bar 51 journaled in bars 52 secured to the framework, nuts engaging the bolts and the rocker bar to provide for tensioning adjustment of the said belt or belts 4:8. The bolts 50 are engaged by hanger bolts 54 depending from a transverse bar 55 secured at its ends to bars 52, and nuts 56 engage the hanger bolts and rest on bar 55 to support the rollers 49 at the desired height above the conveyor belt 34;, being noted that a ton sion spring 56 on rocker bar 51 tends to hold the rollers 49 yieldingly depressed, the ends of the spring being secured to a bar 52 and a collar on the rocker bar.

In the horizontal plane of the space between the conveyer belt and the roller 11, and at the side of the framework w ere the imprints on the books are to be made, a horizontal printing wheel 57 is secured on a vertical shaft 58 journaled at its lower end in a step or socket-bearing 59 secured upon the shelf 5, and at its upper end in a bracket bearing 60 secured to a bar 61 connecting one of the legs 3 and an upright 6. ri-ircuz-ite printing elements 62 of rubber, metal or other suitable material are provided on the periphery of the wheel 57 opposite the space between the rollers 10 and 11, and in such horizontal plane the wheel has a diametric passage 63 containing a pair of pins G t projected when not prevented as hereinafter explained, beyond the aeriphery of the wheel by springs 65 interposed between the pins and shaft 58. In the proportion of parts shown, the printing wheel is adapted to make a. half revolution with the passage of each book B, and each pin is adapted to intercept the path of travel of and be engaged by a book, the latter being utilized to apply end wise pressure on the pinto start turning movement of the wheel without relative slippage between the book and wheel which might occur if the frictional engagement between the book and type face was depended upon to start the wheel from its position of re a Immediately after the turning moven'ient of the wheel is started, its type face comes into engagement with the adjacent or opposing edge of the book to produce the impression thereon, it being understood that the books in the embodiment shown, are placed fiatf tendant in rapid succession, but that the speed of travel is such that the books are up n the conveyer by an at-v spaced apart sufficiently on the co veye'r, to insure the interposition between them of a pin (i l. The parts are so proportioned in the construction shown, with respectto the length of the books that the wheel shall always turn a predetermined distance.

To effect rotation of the printing wheel after such action is started by the pressure of a book on a pin 64, a driven friction wheel 66 on shaft 9, engages frictionally the lower face of the printing wheel, such face having diametrically-oppositecut-away portions 67 for registry with the said wheel 66 at the end of each intermittent operation of the printing wheel, to remove the driving power therefrom, and to guard against any overrun of the printing w ieel, afriction brake 68 engages the shaft 58;

To withdraw the projected'pin 6% so that it shall not contact with the inking fount for the printing face or faces of the print ing wheel, a strap cam 69 extends around the shaft 58, in the path of an arm 70 depending from each pin 64-, as shown clearly by Figures 5 and 6. The ink fount referred to comprises a perforatedcylindrical cup 71 journaled on a standard 72 upon shelf 5,. an inverted perforated cup 73 fitting tightly into cup 71, with its perforations registering witlfthe perforations of cup 71, and an absorbent pad P, inclosing the latter and adapted tosupply ink to the type face or faces 62 as the latter through frictional engagementwith the pad, impart rotation to the fount, "The cup Tl has a threaded socket engaged by a clamping screw 7st swivelled in the cup member 75, and the latter has a worm-threaded surface 75 engaged by a worm .76 by which it is rotatably. adjusted to cut off or establish communication between the perforations of the cups. Ink may be supplied through a filling cap 77 of ,cup 73.

As hereinbefore stated, the books are deposited successively upon the conveyer, and to provide an anti-friction guide for the books that they may be'brought and held in proper printing relation to the printing wheel regardless of slight variations in the width of the books, or in the exact placement of the latter on the conveyer, a pair of bars equipped with vertical rollers are employed. @ne of these bars 78 is secured rigidly to a bracket 79, adjustably secured at 19"" to a bracket 80 fastened to the upright 6, at the printing wheel side of the framework. A thrust screw 81 provides for adjustment of the guide bar to accommodate wear of the type face or replacement thereof for providing a different impression. The guide bar 78 is preferably of obtuse-angle form with its major or principal portion adjacent the printing wheel to afford a lined resistance for tie edge of the book while the impression is being made on such edge, the

Cal

other portion extending at an angle to the line of travel of the book, beyond the adjacent side margin of the conveyer, to deflect'the book wholly upon the conveyer, if overlapping such margin thereof, and thereby insure continuous operation and freedom from injury to books or dislocations of books from the conveyer.

The other guide bar 82 is for engagement with the back or hinge-edge of the books, and is normally parallel with the line of traveland slightly less than a book Width from guide bar 78. Guide bar 82 is pivotally carried by a pair of horizontal arms 83 mounted pivotally on vertical brackets 841- secured to the framework, torsion springs 85 applying force tending to press the bar 82 and the books toward the opposite side of the machine and hence hold the books even if of slightly varying width, yieldingly against th guide bar 78 and the printing wheel to secure substantially uniform impressions, it being understood in this connection that the adjustment of guide bar 82 by the springs 85, is limited by a screw rod 86, rigidly secured to the said bar and extending through a longitudinallyslotted arm 87 projecting from the adja cent upright 6, a nut 88 engaging the rod and arm to be adjusted toward or from the guide bar to accommodate wider or narrower books.

In view of the fact that the operation of the machine has been indicated in connection with the description of its various parts, it is thought no recapitulation of the operation is necessary other than the state ment that the parts operate as indicated by the adjacent arrows, and that an attendant may remove the printed books from the conveyer or they may be discharged from the delivery end thereof. onto a suitable conveyer or into a suitable receptacle, not shown, as forming no essential part of this machine. It will also be understood that the rollers 10 and 11 hold the books with their leaves tightly compressed or compacted to insure good legible impressions and that the feed belts 48 under the power of the spring 56 and the weight of rollers 49 and the supporting elements thereof, serve to compress the books and force them uninterruptedly between the conveyer and roller 11 where the former is firmly upheld by the bed roller 10. It will be apparent that it is contemplated that the end edges may be printed by proper adjustment of the yieldingly-advanced guide bar 82, the books in this case being placed transversely instead of longitudinally upon the conveyer. It will be understood, of course, that the right is reserved to make all changes properly fallingwithin the principle of construction and mode of operation involved and falling Within scope of th appended the first-named roller 'to prevent sagging of the interposed part of the conveyer under compressive act on of the books, a rotatable printing wheel disposed with its printing face in the plane of the space be tween the conveyer and said roller, means cooperating with and overlying the conveyer for feeding the books between the first named roller and the conveyer preliminary to the printing operation, and means rotatable with the printing wheel for engagement by each book, to impart rotat able movement to the printing wheel.
