CHARLES SEYBOLD AND WILLIAM L. VALIQUETTE, OF DAYTON, OHIO, ASSIGNORS TO THE SEYBOLD MACHINE COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO.

PAPER-TRIMMING lirIACHINE.

Application filed March 16, 1922.

To all QUZLOWl, it may concern Be it known that we, CHAnLns SnirnoLn and lVILLIAM L. VALIQUETTE, citizens of the United States. and residents of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Paper-Trimming Machines, of which the following is a full, clear, and exactdescription, reterence being had to the accompanying drawings, forming part of this specification.

Our invention relates to machines for trimming the edges-of bundles of paper,

' pain hlets. books, and the like, in which the bundles oi paper are with each. single operation of the machine trimmed by the cutting knives for both front and side edges and delivered from the machine, so that the operation is continuous.

In machines of this type. as heretofore developed. the. most eiiective construction has provided an intermittently rotating table with a flat upper surface with four stations. At the first station the piles of books to he trimmed areadjusted in position and held by a clamp, the table is then rotated horizontally and a trimming; ltnite at the second st. ion trims one edge, the table again rotates to the third station. where the other edges of the pile are trimmed and the trimmed piles are then carried to the fourth station. where they are delivered...

()ther constructimis of continuous book trinnners have been also pro ided, but all embodying a horizontal movement of the piles from one station to anothert and in every event to compress and properlv hold t is bundles under the trimming knives. it has been found necessary to provide a paper clamp acting: in conjunction with the cut tinglznives. the clamp tor the cutting lrnite necessarily being released as the piles were moved from station to station. The accuracy of the cut depends very largely on the pressure of the knife clamp, and this pressure varies with the character of the paper and necessarily exceeds the table clamp pressure. lVhile the table clamps to hold the piles have'retained their pressure Serial No. 544,088.

as the piles were moved, nevertheless the release of the knife clamp for each successive operation has always tended to permit the piles to shittv slightly bet-ore the next operation.

lVith the best of the prior machines the piles of books have always had to be ad justcd flat at the receiving station, a matter of considerable di'fiiculty in a continuously operating machine. inasmuch as the natural way to bring a pile of pamphlets into align ment is to them on. their back edges, holding the pile vertically. The trimmings and waste from the cutting knife have hereto't'ore also accumulated at the several stations requiring a plurality ot devices to remove chips and the three trimming knives located in parallel planes and operating upon the same horizontal table upon which the continued piles are loaded and from which the trimmed piles are removed has rendered the machine one of considerable da: ,ger to the operator.

It is to obviate all of these ditiiculties and to provide a massive and exceedingly poweriul continuous book trimmer that our in vention is directed, and among the most noteworthy novel features is the construction in which the cutting table is rotated on a horizontal axis with the tour statimis in planes at right ans es each other and the clamping 1e ices for applying the 0 ampinn pressure for the cutting operations are entirely divorced trom the knife moveme' The piles are held under the requisite powerful varia e clamping pressure fo eX- treme accura y of cut all times hot when moving from station to station and during 'mn' The piles of books at the loading station are adjusted vertically so that the backs of the packages can be readily jogged into alignmentthe chips and cuttings automatically carried to one station for removal and the completely trimmed bundles are delivered at the lowermost station, whence they can be most easily removed on a traveling carrier.

The invention consists. therefore, that most novel construct n and e rengementjot parts to be hereinafter particularly pointed out and claimed, whereby the above results and numerous others are attained.

The machine is provided with a framework construction 1 of the solid and massive character required for supporting the various operating parts.

In this framework is mounted on a hori zontal shaft 2, journaled at front and rear, a' substantial cutting table 3, with top, bottom, sides and ends comprising a square box enclosed throughout and the four sides of this box forming a four-sided cutting table adapted to be rotated on a horizontal axis, thus departing entirely from the usual constructions in which the cutting table is rotated on a vertical axis.

Each side of the box 3 provides a table to a pile of books to bet At the station't, the pac ages are jogged u properly adjusted and clamped. The table is then rotated a quarter of a revolution, which brings this first pile tightly clamped into position for trimming the front edge at the second station 5, at the same time that a second pile is being adjusted and clamped at the first station 1. The next quarter revolution of the table brings the first pile to the third station 6, where the side edges are trimmed by knives operating simultaneously on the ends of'the pile, at the same time the second pile has its front edge trimmed and a third pile is adjusted at the first station. The next quarter rotation advances the first pile now fully trimmed to the last station 7, where the clamp is released and the books delivered from the machine.

The operation of the table is thus intermittent, heingheld rigid and immovable between each quarter turn, while the cutting knives are operating, but there is no stoppage of the machine for loading or delivering, so that the work of the machine is-con tinuous and adapted for high speed.

The four-sided square table 3 is mounted on the horizontal shaft 2 and the table is rotated to carry the bundles to be trimmed from one station to the next by a trammel wheel construction comprising slotted runways 9, 10, 11 and 12, formed .of angle pieces securely bolted-to the inner side or end of the box table, so as to form four runways at right angles to each other and extending from the four corners of the box to the central shaft, and a stud 13 on the gear wheel 14, as the gear is rotated. is adapted to enter the proper runway and thus rotate the box a quarter revolution. with each rotation of the gear. This gear 14i is mounted on shaft 16 and carries a cam 1.5 (Figure 8), which with each rotation is cur red by the roller 17 on the upper end of tie lever arm. mounted on the rock shaft 19 on the fra e. This rock shaft carries an arm 20 with flat bearing end which is adapted to swing under and support the box table at one edge, while an arm 21, with a roller 22 at its outer end mounted on a rock shaft supports the table at the other lower edge. These two rock shafts 19 and 93 ha e depending arms 24 and 25 which are coupled by a rod 26 secured to the lowercnd of arm 25 and pass ing through a slotted opening in arm'Q-i, while a coiled spring 27 on the rod 96 and bearing between these two arms tends to maintain them in parallel position. The cam surface 15 is so timed in itscontact with roller 17 that simultaneously with the en trance of the stud 13 in the trammel, the shaft 19 will he rocked. to withdraw'the sup porting arm 20 and to compress the-spring 27. The table is thus released for turning, and just as it reaches a quarter turn the cam 15 releases the arm 1S and the spring 27 the other returns the support to its normal position, the tension of the spring being enhanced by the rock arm 25, which is rocked inwardly by the contact of the edge of the table with the roller 22, the spring 27 also returning the roller 22 to support the table at the other edge.

For feeding the books to be trimmed and clamping them upon the cutting table we provide as follows: On the left side of the machine in line with station 4 we provide a feed trough 30 provided with a bottom 81. and side walls 32, 33, adjustable for various sizes of pamphlets or other material to be trimmed, and in this trough the piles are placed with the backs of the books down, so that they can beeasily jogged into align ment.

This feed trough extends up to the loading station 4 on the table and its inner end lies in the pathway of the table as it is ro tated. lVe therefore provide for swinging the trough out of the way as the table is rotated. The feed trough is supported on a vertical standard or frame 150 which ex tends down along the side of the main framework and is formed with a bearing which is keyed to the horizontal shaft 142. suitably mounted on the frame. This shaft has keyed to it at the inner end a sleeve 143 which carries an arm 145 which extends up wardly to the top of the table and thus serves as a vertical support for the table. The standard 150 and arm 145 are held under spring tension by the spring 146 (Figure 1) bearing between a bracket 147 on main frame and a lug on the lower end of the standard. hen the table is rotated, the movement tips or swings the feed trough outwardly into the position. indicated by dotted lines in Figure 1. thus allowing the lower edge of the table to pass, and the spring 146 brings the parts back to normal.

Onlhe table at each of the four stations (Figure 7) there is secured a back gauge 34 and a cutting; board 35 and-a side gauge 36 all adjustable as is usual for such machines. The pattern board 37, of desired size, is secured to the holder 38, which is swive-led at the outer end of the clamp arm 39. which is securely bolted to the clamp bar 40.

These clamp bars 40. one for each clamp devi e. extend into the inside of the enclosed cutting table through able openings. and each clamp is actuated by powerful le er 4, one for each clamp. These levers are pivotally mounted on short shafts mounted in bearings 42, in transverse plates 149 spaced apart near the middle of the table box and each lever carries on its inner end a roller 43. which bears against a cam 44 on the shaft 2. As the shaft 2 is stationary and the cutting table rotates these rollers are pressed outwardly by the cam 44. The inner portion of each clamp bar is formed into a hollow box 151 closed at the inner end ex rept for a small sized opening. Seated in this box is a heavy coiled spring 47 and inside the coils of spring 47 is a lighter spring 48 which projects through the opening in the end of the box and bears against the end wall. A pin is mounted transverse the sides of the box. Each lever 41 is formed with a nose 152 which engages between the pin 45 and a washer 46 interposed between the lever and the coiled springs.

lVhen the high portion of the on m 44 en gages a roller on the lever 41, the clamp will be brought down to the paper pile and caused to engage and hold its respective pile under the tension of the spring 47. As soon as the lever is released from the cam, the lighter spring" returns the parts to normal and releases the clamp.

In order to adjust the position of the cam, the shaft 2 extends through the bearings of the cutting table and is provided with a disk 50 having a notch 51 engaged by a springpressed pin or latch 52- mounted in the easing As long as the disk is held locked by this latch. 52 the clamp pressure will be maintained by the cam 44, but should the pressure become too great, the disk. and with it the cam, will be released to turn with the cutting table.

It will be noted also that the cam 44 is so disposed with relation to the operating levers, that when the side of the table reaches the bottom station, the clamp will be released and that the clamp at first station will also be released and that as the table is started from this station, the clamp is at once applied to rigidly hold the pile from that point past the two trimming; stations to the delivery station.

At the second station 5, the front edge of the pile is trimmed and at the third station 6, the two ends are trimmed. Of course, it will be understood that this order of trimmine; is merely a matter of preference and that the two parallel knives could be arranged to trim first.

For operating the knife we provide a massive frame of side wa ls and arch 55 in which is journaled the shaft 56 in hearing 57. This shaft is coupled by a segment gear 58 with a rack 58 on the knife carrier 59, which is mounted to slide in dovetailed runway 60 in the frame. The knife frame 61, to which the knife 62 is bolted, is mounted by dovetail mortise 63. so that it can be adjusted laterally for the front edge of the package to be trimmed.

The shaft 56 is rocked in timed relation to the arrival of the clamped package for actuating; the knife by the crank arm 64 coupled by yoke 65 to the rod 66, which is in turn coupled to the crank arm 6'? she 68 iournaled in the frame. This shaft carries a gear 69, which is by .end of the driving shaft 76.

pinion on the end. of shaft 71 with journa l bearings 72, 78, on the side ofthe frame. The other end of shaft 71 carries a gear 74- which meshes with pinion 75 on the inner H LooseEy liGtl on the outer end of the driving a driving pulley 7? and fly Wheel 1b band 79 within which is mounte I ir-in baud clutch member 79, which is expanded by the sliding collar 8%) keyed to but sliding on th y driving; shaft. This collar is shifted to couple the driving pulley to the driving s'ia'tt by the arm 81 mounted on the shaft 82. which is actu v 8 with ed an by the rock arm 88 011 the shaft 84L. This shaft 8% extends across the machine and is provided with the hand lever 85 by means of which the machine is started. To stop the mechanism when the expansion clutch is released, we provide a brake band 86 to engage a hub band 86 on the driving; shaft. T his brake band is held under spring tension in the usual way and adjusted by the tension rod P? operated by handwheel 88. The

open of ds of the brake band have bosses with rollers 89 which are adapted to be engaged by a wedge shoe 90 carried by a rod 9t, which attached to a collar 92 on shaft When the shaft 82 is shifted by the starting lever to throw in the clutch, the wed shoe 90 will be forced in between the o, cs 89 on the brake band and thus will the brake and when the clutch is out. the wedge will be withdrawn permitting the brake band to engage the hubhand on the driving shaft.

The 69 on shaft (58 carrying; the crank arm 67 which actuates the front knife also meshes with the gear 14 on shaft 16 which carries the stud engaging; the trammel on c cutting table and the action is timed ,to permit the quarter rotation and locking frame by tongue and mortise and are ad ustable towards and away from each other by the adjusting screwto .etermine thewidth of the end cuts. As it is important that the knives shall cut entirely through the pile, the knives are made in two parts as shown in Figure 1 8. The knife shank. 98 is bolted to the knife carrier and the knife blades 98" are separated and adapted to be adjusted lengthwise in the knife shank by the adjusting screws Vi hen the trimmed package reaches the final station at the bottom of the table and the camp is released as heretofore described; the package is automatically deiivered to an endless traveling belt 101 for delivery from the machine by a pusher 102 on the end of a push bar 103 uided in casing 160 secured in the frame) and coupled to a rock arm 10%- on rock shaft 105 journalcd in bearings at the bottom of the frame at the 1' This rock shaft has an arm 106 carrying a vertical rod 10. which loosely engaso an eye 108 on a collar 109 secured to the rock shaft 56., which drives the front knife and a coiled between the eye 108 and the arm 10%. Thus with each operation of the ti e the first trimmin station, the p hair i actuated to deliver the fully trimmed piles at the delivery station.

In orderthat the pusher plate 102 may be readily adjusted for piles of varying sizes, we prefer to construct the pusher plate of L-shaim as shown in Figure 16. Both arms of the L are provided with slots lei and162 on the base of c roovcs 1635 16 i, the pusher bar 103 is provided with a tongue 16:? to in either groove and held in adted position by the screw bolt 166. In this w i while he pusher bar 103 is held in up" ,ht i-osition the pusher plate can be shifted into any position desired to cover any of package At the same time that trimi'ned packages are delivered, arrangement is made for removing the cuttings a til chins whch have been severed by the trnnmino knives. The four-sided cutting table-lends itr most effectively both for the deliver of the trimmed books and also for the moral of cuttings. At the same time that the trimmed books reach the bottom station. the chips, which have accunnilatcd when the cutting surface was in horizontal po ition th e and which are the result of the end. cuts drop down and are deposited upon an endless traveling belt 128 running; over drums 128 and 128 The travelingbelts for both the chips id the book delivery are operated the mechanism.

Mounted on the front e is a pulley 123 carrying a turned at right angles by the idlers 124; to drive a pulley on the she ft which carries the front drum 128". -To insure the proper drive of the belt 128, we prefer to mount on the pulley shaft a pair of sprocket wheels with sprocket chains 12? running over idler sprockets on the drum 128 @n the far end of the pulley shaft an sprocket is mounted which carries a sprocket chain 130 which runs over idler sprockets 140 and thence in opposite directions over the sprockets 131 and 132. The front Sprocket 131 also drives the front roller 133 over which and the inner roller 133 the endless belt 101 runs by which the trimmed books are delivered, and both the belt for chips and the book delivery belt are made up of strips spaced slightly apart as shown.

Asthe books are delivered automatically by the pusher 103, it is necessary to have the receiving belt 101 in a position to receive any sizes of books and therefore it will be necessary to adjust the endless belt construction longitudinally. F or this reason the framework 134 in which the parts are carried is mounted for such movement and arranged to be adjusted by the screw 13:3.

In order that the heavy weight of the knife carriers and other parts in the event of some accident or breakage should not cause the machine to run backward and the knives descend, we provide a device to prevent such occurrence (Figure 17). Mounted on the shaft 76 is keyed a collar 170 in C()1l tact with a plate 171 bolted to the framework. This plate has pivoted on it a plurality of spring-pressed dogs 172 with cum ends which engage the periphery of the collar 170. The cam surfaces of these dogs are so formed that with the shaft rotating in its normal driving direction, the dogs lie loosely on the collar. Should, however, the shaft 7 6 be turned in the opposite direction, the dogs will immediately lock the shaft.

e have illustrated the driving power of the machine as furnished by an electric motor 112 mounted on the side of the frame with the pulley 113 on the armature shaft connected with the driving pulley 77 by belt 114, but, of course, the power may be furnished in any other way.

The operation of the machine has been fully described in connection with the detailed description of the parts so that it would hardly seem necessary to repeat.

It will, of course, be understood that there are many well known mechanical equivalents for driving the various parts in timed relation, and that the failure to mention such equivalents is not to be considered as evidencing any intention on our part to limit our invention to the specific devices shown. In illustrating specific mechanism it is to be understood that such mechanism embodies our preferred construction only and it is not to be understoodas limiting us to such specific structures.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is
