- Be it known that I, JAMEs'A. KEYEs, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Im rovements in Packing-Machines, l ie followin is a specification, taken in connection with the accompanying .drawings, which form a part of the same. This invention relates to packing machines, and relates especially to machines in which articles, such as Wra ped packages, are supplied along 'a chute in t e path of a transferrmg-plunger which operates to succes sively transfer rows-of these articles to a carrier. This carrier in the embodiment of the invention illustrated is actuated when acomplete layer of articles is supplied to it to insert this layer into a box or receptacle supported in suitable guides ad'acent the car- I rier, the box being fed forwar intermittently by suitable mechanism.

In-the accompanying drawings, in which the same reference-numeral refers to'similar parts in the several'figures, Fi view of an embodiment of t 's invention.

Fig. 2 is a longitudinal secti onal view of the same. Fig. 3 is a lan view, partl in section. Fig. 4 is a si e view taken in t e opposite direction 'from Fig. 1. Fig. 5 is a transverse sectional view. Figsfi, 7, and 8 are details.- Fig. 9 is a longitudinal sectional view showing the box-feeding mechanism.

Fig. 10 is a transverse sectional view of'the" same. Fllgllisadetail.

In-the lustrated embodimentof this invention wrapped articles 318 are indicated as being fed along thechute 325, and these arti- 'cles may issue from a suitable wrapping-mao e trans-. I ferrmg-plunger 219is mounted-ad'acent this chine in which they-are formed. J

- chute to transfer articles to the a jacent table 225. "(Indicatedin Fig. 5.) This pluner 1s supported-upon the-rods 220, mountedin the lugs 221, and is connected by the short link 218 with the plunger-arm 217, which is shown as pivoted about thepin 238. f The plun er-crank 215v is loosely mounted uponthe p unger-shaft 205 and is connected by the hnk 216 with the plunger-arm mentioned, so

that upon th'e rotation of this crank the plungel is reciprocated through this' conneeting mechanism. A' suitable trigger222'ismountt ed inthe path of the articles, this trigger being indicated as secured to the trigger-shaft 223, which is mounted-in suitable bearings in re 1 is a side.

clutch 207 which is indicated in Fig. 6 as pivoted about the pin 208 in the lug 206, securedto the shaft. This clutch 207 is spring- 209 in the sleeve 210 of the plunger-crank, so that when this clutch 207- is in the engaged position indicated the plunger-crank 1s rotated by the shaft 205, and the plun er is thereupon reciprocated. The elevate portion 211 of the clutch-slide 213 is formed of such height that when the parts are in the position indicated in Fig: 1 the tail of the pawl or dog 207 is engaged by this part of the slide 213, and the pawl is thereupon raised out of engagement with its cooperating notch and the As soon, owever, as the trigger is en aged by the leading article in the c slide 13 is moved, so that the-lower depressed eration with the pawl, which is thereupon a lowed to engage-the notch 209, the parts assuming the position indicated Flg. ,6 and cated.

The receiving-table 225 is mounted on the rigid frame of the machine, comprising the numbers 320, 321, and 322, and is formed with suitable grooves which su the reciprocating inserting-carrier. e'cated as havin its bottom formed of a series of' lates274, tting within the s1ides', of-th'e tab e, and thus accurately guided carrier is preferably given the inclosed form indicover 273 272 to form an inte 31 structure. The rods 3.23 may be secure to the carrier andpass serving tosupport the carrier when in its ad- Vance position. Any desired means inlay be used for operating this carrier, the links pressed, so that it tends to engage the notch.

pllunger crank remains stationary.

ute the c utchcarrier 1s mdi-z through suitable bearings 319, these rods 270 being indicated as pivotedlto the lugs 271 on the carrier-back 272 andbeing connected This slide is mounted on .and drive-shaft 20 1 carries the spring-pressed portion 212 of this slide is moved into coo the transferring-plunger 219 being reciprocated in Fi 2, the bottom plates 274 and the eing rigidly secured to the back at their other ends to the arms 269 on the rock shaft 268, which is mounted in the brackets 275. The arm 267 on this rock shaft is connected by the link 266 with the crank 265 on the cam-shaft 257. The gear 256, which is secured to cam-shaft 257, meshes with the driving-pinion 255, which is loosely mounted on the drive-shaft 201 and operatively connected therewith at the proper intervals by a suitable pawl mechanism.

The latch-bar 242, which is mounted in the path of the leading row of articles in the carrier, is preferably formed with the notches 243, (indicated in Fig. 3 so as to accommodate the folds of the wriippers on these articles. This latch is mounted on the latch-bar 240, secured to the latch-rod 241 and normally held inward in o erative osition by the spring 314. This atch -rod whose outer end is mounted in a suitable bearin in the member 2440f the frame, carries the atch-finger 245. The outer end of this finger engages the pivoted detent 246, wihch is shown in Fig. 8 as engaged by the spring 249 and pivoted about the in 248.

'T e pawl mechanism used to connect the driving-pinion 255 with the drivin -shaft 201 comprises the spring-pressed paw 250, pivoted in the lug 251 on the drive-shaft and adapted to engage the notch 254 in the sleeve 253 of the pinion. As long, however, as the latch-finger engages the detent and holds it in the position indicated in full lines in Fig.

-8, the pawl 250 is held out of, en a ement with the cooperating notch 254 an t e pinion is disengaged from the drive-shaft, the inserting-carrier being thus maintained in inoperative position. When a fulllayer of articles has, however, been transferred to the carrier, the leading row of these articles engages the latch-bar 242 and through the connecting mechanism described lifts the latchfinger 245 away from the tail of the detent, the parts thereupon assuming the dotted positions indicated in Fig. 8 and the nose of the pawl 250 being spring-pressed into engagement with the notch 254. The carrier is thereupon reciprocated and inserts the full layer of articles into the box,the latch and clutch mechanism being held in o erative position during this interval by any esired means. As indicated, the link 270 is shown as formed with its outside face substantially flush with the back of the carrier, and the latch-bar 242 is adapted to ride upon the outside face of this link, and thus maintain the latch in proper position until the carrier once more resumes its receiving position. (Indicated in Figs. 2 and 3.) Then the latch-bar is pressed forward by its sprin and the latch-finger 245 rides down the-inc ined portion 247 of the detent, and the parts of the pawl mechanism once more resume the position indicated in full lines in Fig. 8.

A suitable stop is preferably provided to remove the articles from the carrier on its rearward movement, so as to leave these articles in position in the box. A series of stopfingers 264 may be employed for this purpose and may be mounted upon the arms 263, operating in the slots 315 and secured to the shaft 261, mounted in suitable bearings in the lugs 262. The arm 260, which is also secured to the shaft 261, is provided at its outer end with the roller 259, which engages the stopcam 258 on the cam-shaft 257. By this means the sto -fingers 264 are withdrawn below the level 0 the table 225, when the inserting-carrier moves forward into thebox; but as soon as its rearward movement commences the stop-fingers rise through the slotted bottom of the carrier in front of the articles therein and discharge these articles from the carrier, leaving them in proper position in the box. A suitable stop may also 'be employed between the chute 325 and the table 225 to keep the articles transferred into the carrier in roper alinement. This sto may take the orm indicated in Figs. 5 an 7, the stop 235 being indicated as formed with suitable rods 233 at its lower end, which are mounted in guides in the brackets 234. The link 232 connects this stop with the rock-lever 231, pivoted about the pin 237 and engaged by the spring 236 indicated. The free end of this rock-lever cooperates with the cam 230, formed on the sleeve .210 of the plunger-crank 215 on shaft 205, so that when the transferring-plunger 21,9 begins to move forward the stop 235 is momentarily withdrawn by the cam below the surface of the table. Thereafter the spring 236 raises the stop behind the articles into engagement with the under surface of the plunger and as the plunger moves backward the sto moves upward into the notch 358 and ho ds the articles in position in the carrier, thus engaging them before the articles are released by the plunger.

The box-guide 296 is rigidly secured to the frame and serves to keep the boxes 324 in proper position as they are fed downward into cooperation with the inserting-carrier. Suitable feeding means which may take the form of the feed-chains 287 are mounted adjacent the box-guide and serve to control the feed of the boxes in the machine. As seen in Figs. 9, 10, and 11, each feed-chain 287 is mounted upon the sprockets 289, secured to the shafts 285, the lower shaft being connected by the bevel-gears 284 283 with the transverse feed-shaft 282, so that the feed-chains are operated in unison. A series of springpressed lugs 288 are secured to the chains, these lugs, as indicated in Fig. 11, being pivoted about the pins 327 and being provided with a suitable spiral spring 330, the end of each lug operating in a suitable slot 328 in the pivot link 329 of the chain. These lugs are spaced apart on each chain at distances corresponding with and equal to a multiple of ITO sides of the boxes.

tances being different from the height of a box and preferably being less than the height of a box by asufficient amount to compensate for the thickness of the adjacent As is seen in Fig. 1, the

feed-shaft 282 is opgrated by a suitable sprocket-chain 280,

W ch passes through the aperture 317 and is driven by the sprocket 279 on the stop-shaft 278. This shaft is intermittently rotated by a Geneva stop-motion, the roll on the lug 276 upon the camshaft engaging the radial slots in the starwheel 277 on the st p-shaft, so that every time that the insert g-carrier operates the boxes are fed downward a distance corr'e-' s ondin to the thickness of a layer of arties. T e ivote'd discharger 295, which receives the led boxes, is mounted upon the shaft 293, running in the bearing-lugs 294 and v which is operated by the arm 292, secured 290 on the stop-shaft by the link 291.

thereto an connected with a suitable crank This discharger is arranged .to receive the filled boxes when they are released by the feed-lugs and to swing them out of the boxuide, as is indicated in Fig. 9, so that each led box is turned upward with its open side' uppermost and is laid on the conveyer 308, resting on'the sprocket- chains 302 and 303,- which carry it away. As is seen in. Fig. 2, the'chains 302 and 303 pass over the s rockets 305 on the shaft 306, supported by t ebrackets 307, and over the idle sprocket 304 and the drivings rocket 301, secured to the sleeve 300 on the s aft 357. This sleeye is connected with the s rocket-wheel 299, engaged by the sprocketc ain 298, which also engages the sprocket 2971on the drive-shaft 201. (See Figs. 1 and 3.) After each layer of articles hasbeen inserted into the box-the box-feed operates to feed the boxes downward a distance conesponding to the layer of articles inserted, the

boxes being normally supported, as indicated in Fig. 2, by the spring-pressed lugs 288, which snap outward mto supporting osition at right an les to the chain. (See igs. 10 and 11.) These lugs are adapted, however, to be swung backward into ino erative osition bv engagement with the sidies of the ox, as is s own; in Fig. 10. When, however, the

, filled box is swung outward in the direction indicated in Fig. 9, these lugs as soon as the I filled, box moves out of engagement with them snap outward int'o supportingposition. The lugs thus engage the empty box,'-which descends upon them and which is fed downhold the articles in position in the box, the

ward at unlform intervals until it is filled and remoyed from the guide by the discharger.

series of retainers may be employed to retainer-arms 313 being shown in Fig. 5 as securedtothe shaft 316,mo unted in suitable bearing'si The arm 310 on this shaft engages the retainer-cam 309 on the feed-shaft 282, and this cam allows the retainers to be thrown forward at the time that the discharger removes the box from the guide by the spring 312, which engages the arm 311 on the retainer-shaft. The articles are thus held in proper position in the box at this time, and the retainers also serve to kee the articles in alinement as the partiallyed box is fed down past them.

It is of course understood by those familiar with this art that many modifications may be made in the form, proportion, and number of parts of this machine. Furthermore, parts of the same may be omitted and parts may be employed in connection with other devices without de arting from the spirit of this invention or l bsing the advantages of the same.
