Formed on the lowerend of the cross head 157 is a main stapler operating plate 161to which a pair of stapler heads 162 are adjustably' mounted; Two sets of During this second masts stapling mechanisms are provided on the front of the machine, both identically constructed, one of which will be described. Secured to the stapler head 162 are a pair of stapler driving plates 163 which slidably project into the stapler case 140 and coact with stapler formers 164 to form wire staples formed from wire which is automatically 7 shown in Figure 25, the wire feed mechanism 1671s operated to feeda predetermined length of wire to the stapling mechanism wh ch is automatically operated with each quarter rotation of a former so that staples 168 are driven throughthe hoop strip 108 and the respective box sides 76 to tightly secure the hoop in position around the upper margin of the box to complete the same. vThe operation is as follows:

Having described in detail the various parts-of the improved box. making machine a brief description of the operation will now be given.v The machine is adapted to be driven from any suitable source of power by means of a belt engaged over the loose pulley 8. When an operator steps onthe foot pedal 17 the lever 13 actuates the connecting bar 12 to, cause the bell crank 10 to move the clutch 9 into gripping relation with the loose pulley 8 so that a drive is transmitted from the driving pulley to the shaft 6 and the driving pinion 18. The pinion 18 being in mesh with the large gear 19 acts to rotate the main crank shaft 20, thereby causing operation of a plurality ofdifi'erent mechanisms through the connecting rods 23 and 153 and by means of the cross head 157;

The reciprocating connecting rod 23 is adapted to intermittently rotate the timer gearratchet 28 by means of the pawl 25 to rotate the shaft 26 and the toothed cam 42 (Figure 5) to alternately cause operation of the mutilated gears 37 and 46 which inturn to the outside of the respectivebox sides and is stapled thereto to form a completed box, as shown in Figures and 26.

At this stage in the operation the cross bar 56 acting on the advanced holder 69 retracts said holder causing the release roller 132' (Figure let) to ride over the sliding cam 129,

thereby sliding the yoke 134: upwardly to release the spring controlled presserroller 138 from rolling contact with the hoop 108 of the completed box. As soon as the slide cam 129 passes the roller 132 the frame 134 and the roller 132 arepermitted to'drop off of the straight edge of the cam 129, thereby permitting the presser roller 138 to again be lowered. As, the holder 69 is moved away from the former and the completed box thereon, the spring pressed ejecting pins 94 automatically act to push the completed box outwardly off of the former so that as soon as the holder is moved out of the way an operator may remove the partially ejected box from the gformer on which it was made.

The duplex machine is so arranged that when one of the holders 69 moves outwardly toward a loading position the other holder is in its inner position coacting with its respective former to permit a box to be formed, as hereinbefore described. Themachine is thus capable of forming boxes on the two formers 77 with an attendant placing the creased body blanks inthe holders when in their outer inclined positions. The attendant also feeds the hoop strips onto the tracks 115 and catches or removes the completed boxes as I they are ejected from the respective formers by the spring impelled ejecting pins 94L.

At the time that a holder is retracted from coaction with its former the spring impelled box release pins 94 are, of course, projected outwardly, but the box slide release pins which were projected inwardly by the inward movement of the holder remain in position with their chamfered ends projecting from the rear of the former until the holder is retracted and the box removed so that it becomes necessary to project said pins 90 outwardly through the front end of the former before the next inward feeding movement ofa holder. During the time'that a' former is rotated through one complete revolution to permit the first lap of a hoop stripto be engaged around a former the reciprocating frame 111 is reciprocated, thereby causing the chamfered finger 112 to be brought into thin sheets of wood or other suitable material and out of a hoop constructed of flexible wooden strips or other material permitting the use ofwire staples to hold the hoop se- 1gured to theupper peripheral margin of the We are aware that many changes may be made, and numerous details of construction may be varied through a widerange without departing from the principles ofthis invention, and we therefore do not purpose limiting .the patent granted hereon, otherwise than necessitated by the, prior art.
