The feed drum 17' provided with two dia netric recesses 63, best shown in 4,,

and rocker shafts 64 are mounted to traverse 'said recesses, each .of said rocker 'shafts carry ng a plurality of gripper fingers '65 adapted and arranged to grip the edgesof the signatures held by the stops 48, asexplained above. 1 7

At one end, the shafts 64 project from the V t 1 drum 17 and carry rocker arms66 connected with rods G'T'carrying compression springs68- and adapted and arranged toswing-across a' dead center and operate "to hold said" clamp-- i-ng fingers in either their operative or inoperative posit ons, as, will VbeTreadily' understood; 'At their other ends, each of the shafts 64 carriesa cam headi'69'co operating" a I with a corresponding stop pin 70 on the corresponding end of the drum l'fias best shown 5 r in Fig. -E'ach of the cam heads 69 i's alsol' "prow 'f de d *withcam" grooves 71*jan'd 7 2 cooperating withcam pinsfi and 74mou nted on tl-ie frame "of the machine.

In .this posh tion of trigger 79, its rear lower edge registers with the rear lower edges of the. stops 48.

The arm 78 is secured to theend'of a rod 81 passing loosely through a bracket 82 on the V shaft 49 and adjustable by means of an 7 "adjusting nut 83 threaded thereon and have ing a swivefled connection with an L-shape'd arm 84': on said bracketand whereby the position of the arm 81*and therefore the trigger i finger 79 may be nicely adjusted to be held 90 in the position indicated in 8 by the prop er-1y positioned signature 44."

The cainplate'90 isprovided in its inner face witha cam recess 93 set in the path of roller 89 and so that when of the rod,85 passes loosely M the roller 89ar'rives oppositehhe recess;93, i

if the lever87 and the rod 85 are otherwise free; the rod85 and lever 87 may moveinwardly; The rod 85 is free 'whenjthe trigger 79 drops out of registration*withiits Finner end. The lever 87 i's free when roller 89 registers with cam recess 93. [It thus re quires' the concurrentandsirndltaneous oefcurrenc'e of these two cire'umstancesbefore'tlie r'od'85'and lever 87 'are'free to move inwardly. The lever'87 restsag-ainst the inner side of a stop'fi'n'ger 94 seeiired to the end of the rod -85'and' extends downwardly and rests age it the cuter-'silde'ot a rock-er arm 95'en"the upper end of an inclined rocker sh aft96 mounted on 'the corresponding side of the-j frame '10, as

Arranged at train of'gears and co-operating with asuitable fhopper or receptacle -132containing a stack of articles or objects 133, such as the 125 the outer end of thetablel126 isfa pair of i I feed rollers 130 and131 driven by the same leaves or pages of v a book, "to be, inserted..i conjunction with the signatures 44. The' stackof book pages133 rests upon a -vertical- 1y m ing p t r table l send a P 1 matic extracting drum 135 {isarranged, as shown, in contact with .thetop of said stack, said extracting drum being provided with suitable pneumatic vports 136. Suitable driving mechanism is provided, as shown,for. the extracting are arranged for-producing'suction;or a partial vacuum in the ports 136 to periodically extract-the up'permostjbook page 133 and deliver the same between the guides 137 and 138 to the feed rollers 130 and 131, which in-turn deliver said page along the *topof table 126.

to the rollers 128 and the co-operating balls 129.

The extracting drum 135 and the co-operating receptacle 132 are parts of a well known feeding mechanism now in general use and require no further description here beyond the statement that they operate to remove periodically the uppermost book page or leaf from the receptacle 132and propel the same along the top of the table 126.

As best indicated in Figs. 4, 5 and 6, a rocker shaft 139 similarin all respects to the rocker shaft 49 is associated with the delivery end of the table 126 and the top of the drum 18, said rocker shaft carrying bifurcated stop fingers 140 adapted and arranged to stop and position the pages 133 fed along the top of the table 126.

As best shown in Fig. 3, the rocker shaft 139 carries a rocker arm 141 carrying a set screw 142 contacting with the end of a lever 143 carrying a roller 144 running upon the periphery of the drum 18. The drum 18 is, to all intents and purposes, a duplicate of the drum 17 and the roller-144 is set in the path of the cam recesses 58 in the drum 18 and 1 whereby the stop fingers 140 will be operatr and whereby when said ed in conjunction with the gripper fingers to position and release the book pages 133 when gripped by the fingers 65.

It will be noted that the distance of travel between the point at which the book pages P the fingers 65 and the the drums 17 and 18 is considerably shorter than the corresponding distance of travel of the signatures 44 on the periphery of the drum 17. For this reason the cam pins 73 and 74 for the drum 18 are positioned somewhat closer together and the port 7 5 in the hollow shaft 12 is somewhat shorter than the port 75 in the hollow shaft 11. Otherwise the drum 18 is identical with the drum 17 and needs no further description beyond'the statement that it operates to feed the book pages 133 into juxtaposition with the signatures 44 so that the'book pages will be attached to said signatures by the glue or adhesive applied thereto as explained above signatures are dis- 133 are gripped by point of tangency of drum- ,135 and suitable connections charged. from the machine as explained above; h y wi ve atta ed the e the book pages 133 and so that when said signatures are ultimatelyassembledinto .the'book' for which they are intended, the book pages l33will be associated therewith in said book running upon the periphery of aca-m disk 150 on the shaft'91 containing a recess 151 c0- operating with said roller and so positioned v I as to permit movement of the'lever '148 in case there is a failureof the feeding appa ratus to feed a book page 133 at the proper time just as the lever 87 operates in the case of a similar failure of thefeeding 'ofthe signatures .44. v

The rod 147 carries arm 152 co-operat I ing with an arm 153v onthe shaft96 and op erating to turn the shaft 96 upon such failure of the feed of a ping the machine just as the failure of the feedof afsignature 44 stops the machine as explainedabove. It will thus be notedthat inthe caseof the failure of either; of the feedme properly, the machine will vbe automatically stopped thereby books assembled from the signatures threaded by the machine.
