A: C QRPO RATION OF MASSACHUSETTS I g oonvnxinn MECHANISM deflected onto a branch guideway 12, while other boxes C continue along the main guideway 10. Located along the main guideway 10 beyond the deflector mechanism are a plurality of operator stations 13, ten such stations being 'here shown, while located along the branch guideway 12 are three other such operator stations 14. The articles approaching the deflector mechanism 11 pass first through a spacing device 15 which may be of any desired type as for example that shown in the application of Chester S. J en nings, Serial No. 465,098, filed July 1, 1930, by which the articles are spaced a predetermined distance apart and thence through a device 16 by which the operation of'the deflector arm is controlled.

The purpose of the present embodiment isto separate the boxes approaching over the main guideway into two groups, one, con taining ten boxes, continuing over the main 'guideway, while the other, containing three boxes, is deflected onto the branch guideway, such separation being performed automatically without necessitating the attention of an operator. The deflector mechanism 11, illustrated in Figs 2 and 3, to which attention is particularly directed, comprises a deflector arm 20 of the well known type mounted at one end upon a shaft 21 suitably supported in a bracket 22 secured to one of the side rails 23 of the main guideway, between which travels a conveyer belt 24. Secured to the shaft 2] is an arm 25 connected by an extension 26 to a link 27 carried by the core 28 of a solenoid 29 suitably supported by a side rail 23- in any desired manner. A spring 30 extending below the belt 24 normally holds the arm 20 in the open position resting against a stop 31 also carried by a side rail. When the deflector arm is in the operating position boxes transported by the belt 24 are deflected into the branch guideway 12, here shown as including a conveyer belt 35 which travels swung into the operating position against the tension of the spring 30. The solenoid 29 is in a circuit 40 which also includes a normally-opensw itch,41, here shown-as of vthe mercoid typed? Such a switch is open 'when horizontal as shown in Fig. 2 and, closed w n t tedi. t e e u y th r in flowing the end-of the tube that the current will traverse-m asu'itable' 'source of supplythrough the core 29, energizing it and causing the deflector arm to be swung, into, the

operating position.

The switch 41 is a partof the control device 16 shown at the right of Figs. 2 and 3, being carried by a suitable frame which extends iabove theimainjguideway and on whichis supported a transversely extending shaft 51 ;An,arm 52-hereafter referred to as;:a trip vis pivotally mounted at its upper endon thfshaft 51 and extends, into the path of travelofthe-articles-so that it is actuated by each article-as it passes through the controldevice. The trip 52,' as%'shown-;in Fig. 4, preferably comprises apair of plates 53 separated; by blocks 54, 55. In a-pocket in the block 54: is'mounted a pawl 56 normallyheld extended by aspringr57 in the position shownin Fig. .4. Carried by the shaft 51 between the plates 53 is a ratchet wheel '60 suitably; spaced by-collars 61from the plates 53, the teeth 62 of the ratchet being normally inscontactwith the pawl '56- Secured on each side-,of the ratchet are al enate-blocks 63 which, inthe present instance,-.span the distance defined by three of the-teeth 62. *As shownparticularly in Fig. 5,'the ratchet 60 is provided with twenty-six teeth 62 and the blocks 63 are diametrically arranged in pairs separated by ten teeth. Pivotally. mounted between two angle plates 65, carried by the upright 50 is a tongue 66 on which is supported the mercoid'switch 41-. One end of the tongue 66 is supported on a stud 67 carried by theplates 65,- while the other'endnormally rests on a cross pin 68 also carried by the plates so that the switch is inits: normal position with the circuit open. The end of the tongue 66 which rests upon the pin 68 terminates in a yoke formed by fingers 69 separated by a space 70 through which the ratchet 60 normally moves without interference. A pawl 71, carried by the plates above the tongue 66 normally en gages the teeth 62 and thus prevents the travel of the ratchet 60 in other than the clockwise direction indicated'in Fig. 2. The projecting fingers 69 of the tongue 66 extend into the path of travel'of the blocks 63, so that when engaged thereby the tongue is step. This movementof the rat chet out of the position shown in Fig. 2 brings-' two of the blocks 63 into contact with the fingers 69, tilting the tongue 66 and thus through the switch ll closing th circuit {10, energizing the solenoid 29and'carryingthe arm 11 into the position shown in Fig.3. The arm remains in'this position until the trip 52 has been actuated by two more boxes A and since the boxes are equally spaced it will be apparent that during this time three boxes will be deflected from the main-'gui'deway onto the branch guideway. When the third boxactuates the trip 52'howe'ver, the blocks 63 pa$ beyond the fingers 69 and the tongue is returned by gravity to :the: normal position shown in Fig; 2, which position itretains until another pair of blocks 63 have-been brought into contact therewith after the passage of ten articles."- Gonsequentlythe train of boxes A is divided into two groups consisting 'of ten boxes-which pass to theoperatorstations 13 and three boxes which pax to the operator station 14. This division of the boxes continues as long as boxes are being fedto the control device.

While the operation. of this device hasbeen described for the separation of the boxes into groups of ten and three respectively, it" is obvious that by changing the positions of the blocks 63 or by substituting for the'blocks here shown blocks which span four; five or any number of-teeth or by substituting for thetwenty-six toothed ratchetwheel 6o, a ratchet wheel having a greater or less number of teeth the train of boxes can be divided into groups of any desired. number. F urthermore, instead of operating the deflector arm as here shown, the control device may be employed to operate a stop counter, an elevator or any other element associated with i the travel of the boxes. v

The feature of this invention is the provision of a control device operated automatically by the passing articles by which the articles are manipulated, and while one'embodiment of this invention has been shown and described, we are not limited thereto since other embodiments could be made without departing from the spirit and scope of the invention as set forth in the following from the guideway, said mechanism including a deflector 'arm,'electrical means which, whenenergized, shift said arm into operating osition, and means actuated by each artic e passing along the guideway toward the deflector arm, which means after actuation by a predetermined number of articles energizes said electrical means, which thereupon shifts the deflector arm into operative position to deflect from the guideway articles which have actuated such means and holds it energized until said means have been actuated by a predetermined number of articles.
