ill??? to that portion of a box machine milazrled to supply and deliver heads to the uiecnanisln for assembling the elements of the heir.

fine object of the invent ion is the provision of an ellicient mechanism for Supporting a plurality of box blanks in convenient poeitiou and delivering them successively from such position.

Another object is the provision of a pi'ac tical feeding mechanism to deliver the box blanks or heads in an accurate manner so as to conform with other mechanism adapted to operate tlicrcon. c

LStill another object is the provision of e'llicicnt guiding and pressing devices to cooperate with the devices to which theheads are fed and insure the exact positioning of the heads on the latter,

The inventionaccordingly consists in thefealiirree of construction, combinations of f and r-irrangcment of parts which :i'n 'liiied in the construction hereinafter set forth, and the scope of the apcation of which will be indicated in the in the accompanying drawings, wherein imilar reference characters indicate similar arts: thri'nighout the several views, Figure I A I n 1' 1 :1 side elevation of the mechanism. partly in array; Fig. 2 is a rear view thereof;

ing certain associated cooperating mecha-. nismi The in ention forming the subjectanattcr of this application is disclosed in applicants prior application Serial No. 492.029, tiled April El, 1909. In said prior amilicalion a ho): is made by assembling a box head and a box flange in predetermined position, folding the flange around the head pasting the ends of the flange together, and pasting an extension of the flange to the bottom of the head to secure the head and flange together. The head and flange are nssemhled on a, form carrier comprising; a huh "210 having a plurality of radial arms 21] arranged equidistant about the hub, the carrier being secured with its hub to a horizontal shaft, 212 journaled transversely in a bearing on the adjacent. parts of the main frame A and rotated intermittentiy by any suitable mechanism so that it coincs to rest at i1.- lervals with one of its arms projecting! vertically upward, and the others disposed at other positions for purposes not here required to explain. The mechanism disclosed to accomplish the intern'iittcnt rotary movement of the carrier comprises a mutilated pinion 213 mounted on a countershaft 206 and provided on one-half of its periphery with gear teeth while the remaining half is plain and concentric, and a mutilated gear wheel F314 secured to the outer end of the rotatable carrier-shaft and provided equidistant on its periphery ivith lour toothed segments or sections which are adapted to he engaged successively by the toothed por tion of the pinion 213 and four locking faces alternating with the toothed sections and adapted to be engaged successively by the plain concentric locking face of the pinion, the relative size and construction of this pinion and gear wheel being such that the gear wheel is turned one-quarter of a rotation by the pinion during each complete rotation of the lattcn and the rotatable carrier is held at rest after each quarter step forward to permit of feeding a box head to ,the carrien and carrying the head to thc flange for assembly therewith.

At its outer end each carrier arm is pro vided with a form, former; mandrel or block 21?} preferahlv of rectangular shape, npon which the head is received, the block being preferably constructed to nerve apnew mat-ii. gripper and having cliennels 219 communicating with a passageway 220 in the carrier arm, which passageway is at intervals placed in communication with an exhaust device. The head is fed from the magazine to the face of the former or block,

and the outer edge of a front jaw Z12, ar-

ranged transversely at the front edge of each former and mounted on the outer arm of a rock lever 243 oh the carrier arm, projects outwardly beyond the face of the former so as to operate as a gage or shoulder with which the front edge of the head engages while the same is being pushed from the bottom of the stack upon the former, the operation of the machine serving to move the jaw 242 into gaging position when the former is in receiving position relative to the heads in the magazine.

The blanks or box heads B delivered to the former are preferably rectangular in shape and composed of paper, pasteboard, etc., as set forth in the pri r application, and are supplied from a stac contained in an upright magazine which is arranged in the upper front part of the machine and which preferably consist of two upright side walls 193 adapted to engage with opposite side edges of the heads, a pair of upright inner flanges or shoulders 194 arranged on the rear ends of the side walls and adapted to engage with the front edges of the box heads, and two upright inner shoulders 195 at the front ends of the side walls which are adapted to engage with the rear edges of the box beans, and a bottom 196 which extends across the lower end of the magazine and supports the stack of heads therein. The heads are feed or removed successivel from the bottom of the stack, in a predetermined path, or plane by means of a delivery device which preferably consists of a horizontally and longi tudinally-reciprocating plunger or follower composed of two sections 197 which are arranged side by side and guided in grooves 198 in the upper side of the magazine bottom, each section being provided with a rearwardly-facing shoulder 199 at its rear end and a cross piece 200 connected with the front ends of the plunger sections. In its retracted position, the plunger is arranged with its shoulders in front of the stack of heads in the magazine and upon moving the same rearward, these shoulders engage with the rear edge of the lowermost head in the magazine and push the same rearwardly from the bottom of the stack and out through an opening or throat which is formed at the lower rear end of the magazine and which is of such height that it permits only one head at a time to be ejected rearwardly from the magazine. After the plunger or follower has thus removed the lowermost head from the stack, it is returned to its foremost position with its shoulders in permitting the latter to pivoted on the adjacent part of the frame and having an upper arm which is connected by a link 2203 with a horizontally and longitudinally sliding bar 204 connected with the follower crosspiece, and a rotatable cam 205 engagingwith the lower arm of the lever 202. The cam 205 is secured to the shaft 206 which is iournaled in bearings on the adjacent part of the frame and is driven through a chain wheel 209 secured thereto, On account of the spring means for effecting the discharging movement of the follower, the feed of the blanks from the magazine is in a yielding manner, such yielding favorably qualifying any tendency to crush or bend the blanks, and substantially avoioing fracture of the machine should any obstruction or foreign object he accidentally presented to the mechanism.

As the box heads are discharged successively from the under side of the stack in the magazine, they are carried one at a time rearwardly, downwardly, forwardly and upwardly in a circular path and each assembled with a flange strip and binder strip, as hereinbefore explained. Each of the formers is carried into a position in rear of the head magazine at the same time that a box headis being discharged from the mags.- zine, whereby this head is delivered on top of the respective former which at this time has its face arranged uppermost. Immediately after the head has been thus delivered upon the former from the magazine, the air grooves of the former and its respective branch passage are connected with the air.

exhaust device. causing the box head to be come pneumatically attached to the gripis effected by V and bring the next following lowerping face of the former. As the box heads are fed from the lower end of the stack in the magazine, the same are guided and pressed downwardly against the face of the former which at this time is moving into position in rear of the outlet of the magazine for receiving the same, thereby insuring reliable attachment of this head to th former by means of the external air pressure which is produced by connecting the air passages of this former with the air exhausting device immediately after the former comes to rest in rear of the magazine outlet. The preferred form of guiding and pressing doe vice for this blank pressing and deflecting roller 236 arpurpose consists of a horizontal rang l transvo sel in rear of the outlet of tbs o line 'nlih its lower part normally inn-:11 ring ilzrpath of tho head which is being discharged from the magazine, two vortirallv lnUYlilllQ rods 23?
