Mounted on the shaft 99 is a gear pinion 104 which is in mesh with a second pinion 105qwhich is mounted upon the shaft 89 which extends transversely across the frame 10 0f the inachine from side to side and on .thefouterzend of which. on the rear side of v the machine is mounted the pinion 78, one
of the train of gears through which power is communicated to the sewing apparatus heretofore described. On the outer side of the gear pinion 78 is a thimble 106 posil. tioned in the gear pinion 78 at one side of the center thereof and which is adapted to engage in recesses 107 in theouter periphery of a star gear wheel" 108 mounted upon a shaft 108 secured to the frame, 10. Be-
tween eachof the'recesses l07fonithelgear 108 is formed a plurality of teeth 109 having a curvedrecess 110 in the ends thereof and into which a hub portion lll of the gear -wheel 78 is adapted to seat, the engagement of the hub 111 into the-recess 110 holding the wheel 108 stationary for a short fraction of time during 'a partial rotation of the thimble 106 which, be cause of its engagement in the recess 107 moves the wheel 108 intermittently in alstep by step motion and thus imparts to the feeding mechanism an intermittent movementv of these parts, thereby feeding the books into the machine and holding them stationary While. one movement of the drill head'49 is made and also a movement of the sewing needle 80. The shaft 31 extends across the frame 10 of the machine and has a gear -112'mounted thereon; at the rear side of the machine rwhichmeshes with a second gearj113 mounted upon the shaft 108 and through which movement is communicatedby means-of the. shaft 31 to the pulley 30 mounted thereon and which controls the movement-of the inner feed belt 33. The shaft 31 has a. gear ,wheel 114 mounted on the outer endthereof on the front side of the machine which'in turn connects by means of-atrain of gears 115, 116, 117 and 118, which lastmentioned gear ismounted upon the shaft 19 carrying the pulley 22- which carries the outer feed belt 26, these gear connections serving to move the two feed belts simultaneously and in 'sync'hronism with the other operating parts of the machine, and in an intermittent step by step movement.
Attached to the outer end of the shaft 89 is wheel 119 which serves to steady the LllflQiZ-TOTiOfChG machine, the said shaft 89 also" having a gear wheel 120 mounted therewhich meshes with a second gear Wheel 121 carrying a' smaller spur gear 122 which is in meshon one side with a gear wheel 123 having an eccentrically shaped channel 124 in its outer face within which a roller'125 mounted on theend ofaa bell crank 126 trayels, the bell crank lever be in-g pivotally mounted on a stud 127 securedto the frame 10 of the machine and having a rod 128 connected thereto by means of a pin 129, the said rod 128 being connected to a pivotally mounted lever 130 at theifront 'of ,th,e ma
chine by means of a pin 30*, the-said lever 130 having a slot 131 at its upper end through which apin' 132 extends into a slid-- ing block 133 which is mounted upon a guide member 134 secured to the frame 10 of the machine in any approved manner. The block 133 has a face plate 135 secured there- 1 to and also-has an arm 136 attached thereto which has a parallel extending screw 137 at its upper end with adjusting nuts 138 and 139 mounted thereon, the screw 137 having a plate 140 attached thereto to which a feed ing member 141 is atttached and which extends underneaththe upper belt 26 and rides upon thetop of the feed table 11 and serves to push the books 42 forward until the books are gripped between the upper feed belt 26 and the upper portion of the innerfeed belt 33, the books being handfed in the front of the block 141 and underneath the belt 26 by being pushed along the to? 'on at the front side of the machine and i I of the table 11 untilthey are "in contact with the guide member 54 which extends at the outer, side of the table 11. A similar guide member 142 is provided at the inner side of the book which serves to hold the books in from pushing out sidewise between the feed belts during the drill and sewing operations.
It will thus be understood that a s'th'e ma; chine operates, the bell crank 126 reciprocates the rod 130 which in turn moves the block 133 and the feeding block 141 back and forth underneath the belt and pushes the -books forward to a point where they are through the machine.
gripped by the feeding belts and carried Mounted upon the lower side of the frame upon a pair of arms 143 is a reel 144 carrying a roll .145 of reinforcing material,
such as muslin, heavy manilla paper or the like, and which is fed over a gum. applying roller 146 mounted upon the upper side. of a receptacle 147 Which is secured to the frame of the machine and from which a strip of material 148 isrun underneath a roller 149 strip is fed underneath the said roller 161 around a second roller 150 to a point immediately above the belt 33 where the strip 14815 fed on top of thebelt 33 with thegum side upward in position'to be applied" to.the books 42 as they are fed-in between the lower belt 33 and the upper belt 26. A similar reel 151 from whicha. strip of 'm a'terial 152 leads is provided which passes over a gum applying roller 153 mounted in a receptacle 154 at the upper side of the machine with retaining rolls 155 and 156 be; .ing provided to hold the strip 152 in contact with the surface of the roller 153 so that mucilage or paste-is applied to the undersurface of thejstrip 152. The strip 152 passes longitudinally of the machine around a pulley 157 carried by a standard 158 mounted upon the outer end of the rod 45 and thence back around another roller 159 mounted upon a standard 160, thence down ward around another roller 161 where the and on to the rear edges of the books 42 after they have left the drill press and before they reach the sewing machine, where both reinforcing strips are sewed to the books 42? as they pass throu h the machine.
It will thus be understood t at reinforcing strips are applied to the books as they pass through the machine uponteach side thereof and are fixed in position by the same stitch- 7 ing operation whichseWs the signature sheets together.
