Fig. 7, is a View looking upwardly at Fig. Fig. 8, is an enlarged cross-sectional detail a stacl; retaining mechanism, and Fig. 9, is a view loolting upward ly at the same. Fig. 10, is a view `looking down upon the three-legged counter device' shown in Figs. 3 and 4,'and Fig. 11'is another View of the saine in its shifted position. Fig. 12, is a perspective view, parts broken away illustrating part of a boX guiding mechanism. Fig. 13, is an en, larged detail of part of the counting mechanism. Fig. 14,`is a front elevation' showing'y part of the stacked box retaining mecha-y nism, andvFig. 15, a view at right angles thereto. Fig. 16, is a detail of the stack shitting mechanism in perspective.

Referring now more particularly to Fig.

.1, it will be observed thaty :the attachment y may be driven by belt or sprocket chain such as 7, adapted vto engage sprocket wheel 8, upon the shaft 9,` upon whic-his also secured the grooved pulley 10. By `reference now .more particularly to' Fig. 2, it will-beob-y served that this grooved pulleyisprovided with a rope or strap drive 11, which vvpasses upwardly from the same over the pulley 12 stack.

and ,beneath the pulley 15, havingcounterweight '16, over the pulley 17, pulley 18, and beneath guide 19, around pulley 20, pulley'21, and around pulley 23, beneath the guide 22, over pulley `2 4, pulleyr 25,y and around the grooved pulley ,10, originally referredr to, from which it Awill be seenthat the rope or strap movesk forwardly and subf stantially` parallel to engage yby friction the sidesot the tray or box such as 25,- which finally reaches the position within therack or frame 26, shown in Fig. 6, the upwardly projecting standards 27 of which arev provided with suitable light springssuch as 28,.shown,to .advantage inFigs. r14 and 15. n Referring now again to Fig. 1, it willbe observed that at the inner end of the shaft 9 there is provided a crank v29, carryingthe connecting rod 30, pivotally lmounted upon the `vertically slotted plunger 31, at the top of which is provided a platform 32 (see` Fig. 3), carrying guidesy 33,` engaging beneath the boxr25"y :isshown in dotted outline at 34. yThis servespto raisey the `box beyond the spring retaining device 2/8, shown tok advantage in Figs. 14 and 15, by. which the boxes are held beneath the bottom ofthe n `Aseach box is lifted, the endof the same striking ther lever 35, pivoted at 36,

lthrows the lower end of said lever leftwardly looking at Fig. 3, `and being connectedby rod 37 to the leg 38, of the three-legged member 39,y shown to better advantage in Figs. 10 and y11theleg 40 of said mem ber is brought in therpatli of the .projection 41 of the centrally pivoted lever 42, upon the same axis with which is alsor mounted the lever 43, pivotally connectedfto therod 44', the lower end of which is yof wedgeshape formation as *showny at 45, and is adapted to operate the cam 460i the pawl 47, pivoted at'48 andretained by. spring 49 which is ksecured. at 50 as shown, so that with each descent of the verticallyy slottedy member 31,1 providing the pawl 47 hasnot been operated by the wedgemember 45, the l pawl 47%pivotally mounted. upon` the same and traveling ,with it, engages a tooth in the ratchet whe-elr 51, therebyurotating ity lett-r wardly onetooth. In caseabox is notlift- .ed'so as to strike the lever 35, `the leg40 bemg inthe path ofthe lever 41,,y strikes lever `41,",Ethereby depressing the rod 44 ywhich 47 clear of the pinion 51, with the result that no count is made. At the same time, the tapered member 111, moving in the path of the hinged member 109, swings the member 109 in the path of the button thereby cutting off the current and stopping the machine.

The ratchet wheel 51 may be provided with say twenty-five teeth, and is also preferably provided with a member 52 which travels therewith, ,and which in 'its travel encounters the end of the lever 53, which is thereby pressed downwardly once each time twenty-five boxes have been pushed up by the machine as aforesaid. As the rod 53 is pushed down, it carries with it the rod 54,- which may be formed therewith, and at the top of which it will be observed by reference to Fig. 3, a sort o-f cap 55 is provided, beneath which projects a suitable resilient member 56, vfrom the top of thelever 57, yso that as the vertically slotted member 31 rises, and the rod 57 is thrown rightwardly looking at F ig. 3, the engagement member 55 Ithereof ybecomes seated and 'locked within` the recess 58 of said slotted member.

At the lower end of the rod 57 is pivota-llyv mounted a rocking arm 59, which is also pivotally Amounted at the axis of the ratchet wheel 62, and at the opposite end of the rocking armr59V is secured the bearing 60 carrying the pawl 61, which engages thc ratchet wheel 62, thereby rotating said ratchet wheel one tooth for each twenty-five 'boxes liftedv above the machine.

After the ratchet wheel 62 has rotated once, which means in the illustration given, live teeth, one hundred vand twenty-five boxes shall havey been elevated in the stacker rack immediately above the slotted member 31, and then the projecting member 63, adjacent the ratchet 62, will be in 'a p0- sition to strike the, enlargement 64, upon the arm 6,5 pivotally mounted at 66, and to which are connected the rods 67 and 68, the lrod 67 being pivotally connected attlie top at 69'to the :lever 70, and the' rod 68 being 'connected tothe lever 71, pivoted upon vthe shaft 72, and being of L-shaped formation, thereby pushing the rod 73 connected thereto rightwardly, which said rod, being pivoted at 74, and having an engage* ment member 75, releases the upper disc 76 upon the shaftr 78, from the lower disc 77 upon the pinion 79, which discs normally engage by friction as a clutch. The shaft 78, at its lower end, has the pinion 79, en gaging the wormv 80, upon the drive shaft 9, and the lever 81 at the Vopposite end thereof has itsV free end bearing 81 free to travel within the guide 82, which ,is part of the stack carriage shown in Fig. 16, and which is thereby reciprocated together with its stack along the guide' 83 lat the top of the machine as shown, which in a few words means ythat every time one hundred and twenty-five boxes have been counted and y stacked, that particular stack is shifted, out

Vo position, and an empty stacking frame .is replaced in position for a new stack of boxes. 1

pivotally mounted at 87 and a stop 88 is mounted at ythe opposite` side and serves as an obstruction for the leftward movement of the stacks, looking at Fig. 1. When the lever 67 lifts, however, the stop 88 is of course depressed out of the path of the stack,

and in moving downwardly carries with it the spring member 89, provided with a stop member 90, which 'is also depressed to clear the path of movement of the stack. As the stack moves leftwardly, the pin 91 traveling in the path of the lug 92, shifts the same, and also the member 93 against the action of the spring` 94, the distanceinoved being allowed for by t-he vslots 95. `This allows the new stack to come into position, afterwhich the stop member 88, having cleared vthe j spring 89. is now free to be operated in the path of the next stack, after which the slide 93 yreturns to its normal position under .influence of the springs 94. The entire column of one hundred and twenty-five boxes will therefore rest upon the ledges suoli as 95 in the base of the stack, and by inverting the stack, may be readily dumped out `by gravity for packing or wrapping as may7 be required, thus providing a thoroughlyautomatic means `for stacking and counting without interruption of the machine in `an' ,Y particular.

Also in the sides of the guides y83-83 are provided suitable vresilient members '96,'

which project therethrough as shown in Figs. 8 and 9to prevent the shifting back of the racks as they are moved forwardly, and these members may be vmounted upon suitable screws suohas 97 and may be provided with suitable springs, suoli as 98' if desired. f

It will also be observed that each time the lever 57 is depressed, being connected'to the rocker arm 59, the rod 99 connected atl theopposite end is lifted, and being pivoted at 100 to the rod 101; lifts the same, together with the frame 102 at the top tliereof,.wh=ich lsaid frame `carries the frame 103 by the rods 104, extending throughfthe table 10.5, the said frame 103 serving to lift each group of twenty-five boXes Which are retained by the fingers 28 and clear the machine entering the stacking framesfabove, so as to leave clearance for the accumulation of the next twenty-live, and so on, and upon the table` 105 may beprovided suitable' standards such as 106, for guides such as 107, Which may be spring retained as indicated at 108, to control the stacking of the boxes before the same are pushed into the stacker frames. y

Referring again to Figs. 3 and 4, it Will be observed that a switch operating vmechanism 109, is mounted upon the slotted vertically moving member 31, and ispivotally mounted as indicated at 110, so thatit can be ythrown out rightvvardly by contact with the tapered member 111, The member 109, traveling with the slotted member 81, is controlled by the movement of the latter. Member 111 being operated'by Contact with the leg 410 controls the position of the tapered member 109 which being pivotally mounted is swung in the path of the button 112 which is depressed, the current being on. If the counter is not operating, however, the tapered member 111 advances ,to throw out the tapered member 109, and it therefore travels in the path of the button 113 which it strikes and cuts off the current,

by the sleeve 122, and the opposite end isr secured to the standard 123, so that normally the Weight of the arms 119-119,v and the light metal deck 124, carried thereby'is supported by said spring. The deck 124, is preferably pivotally secured to the bar 125 carried lby pivoted arms 120 and also piv otally secured to the bar 125, said bar 125 being in turn preferably secured to the arms 119-119, so that with little effort the deck,

124 may be depressed, but in doing so depresses substantially flat or horizontally, allowing a box caught or buckled thereupon, to escape beneath the platform 105.

Of course it will be understood that Vfvarious modifications may be made in the construction and arrangement of parts Without departing from the spirit of the invention as claimed.
