'p The .improved sheet handling mechanismz to which this invention is applied is adaptf cdfor use in many c'liferent types offma.- chines and foi" handling various kinds of articles but, as herein illustrated, the inven tion is applied to a stencil making machine.v

Inasmuch as this invention relates tothe sheet handling mechanism, parts ofthe machine not relating thereto and believed to he unnecessary to a complete understanding of the invention have beenl omitted from thel line ft2-l2 ofl Fig. l, and showing theimconveyor which Ainoves the cards' or other'. Y

sheets seriatimto be operated uponhy the various operating mechanisms. The particular conveyer herein illustrated comprises l anendless chain having projecting parts adapted to engage apertures in the articles,

which, are ted thereby 'y along a supporting guideivay. Tliesheets or cards are. dgliyv ered to the feeding mechanismby an improved delivery mechanisin which, in the specific form shown,V includes a magazine' and means/for moving the lowermostcard i to the plane of the guidevvay for engage- `ment With the lugs or fingers of the con` veyer. An improved ejector is also pr0-' vided for removing the cards `when they reach a certain position on the guideway.

In order to properly position eachf card" when it being acted upon, improved po sitioning means is `also provided fortenn porarily holding the card stationary.` y rp vIn the embodiment shovvmpthelimproved sheet handling mechanism 'y applied to a stencil inakinginachine comprising a frame.,

l on which is mounted a pair'of spaced rails 2 forming a guideivay for supporting and guiding stencil frames 3 Whichare fed through the machine to be operated upon by various mechanisms such as a. gluing` devicell and a pneumatic device fwhichappliesthe tissue patches to the stencil frames;

" gear 17 fixed on a shaft 18.

" sition to be acted upon by the gluing device 4 and the pneumatic device 5. Arranged at the other end of the machine, is an improved ejector 9. l

In the specific form shown, the chain conveyer 6 vis mounted on a pair of sprockets 10 and 11, which are fixed on horizontal shafts 12 and 13 respectively journaled at opposite ends of the machine. The sprocket shaft 12 is journaled ina bearing 14 which is adjustably mounted on a support 15, so as to be adapted for adjustment both vertically and horizontally for properly positioning the chain. Fixed on the outer end of the shaft 12, is a worm gear 16 meshing withY another The shaft 18 is connected to a continuously driven drive shaft 19 by a Geneva mechanism 20 so as to be intermittently rotated for imparting a step-by-step movement to the conveyer chain. The sprockets and 11 are arranged so as to position the upper ruiming part of the conveyer chain adjacent one side of and parallel to the card guideway 2. Mounted on the chain 6, is a plurality offingers or lugs 21 which project over the adjacent guide rail for engagement `with apertures 22 formed in the card frames, whereby the cards or stencils are fed along the guideway. The lugs 21 and apertures 22 are positioned so as to prevent any lateral shifting of the stencils during their travel along the guideway.

In theform shown, the improved delivery mechanism 7 comprises a magazine or hopper 23 in which a stack of cards or stencils is stored and from which the lowermost card is pushed edgewise by a pusher 24 arranged to move the card onto a pair of cams 25 which lift it into the plane of the guideway 2 for engagement with the fingers 21 of the conveyer.

The pusher slide 24 is located `in a guide-- way 26 below the magazine 23 and is reciprocated by a rocker arm 27 to which it is pivotally connected. The rocker arm 27 is pivotally connected at 28 to the frame 1 and is pivoted at its lower end topaJ link 29 having a band 30 embracing an eccentric 31 fixed on the drivel shaft 19. During the continu. ousrotation of the shaft 19 and eccentric 31, the arm 27 is rocked back and forth to reciprocate the slide 24 which, upon each forward movement, pushes the lowermost card in the magazine onto the' cams 25.

The lifting cams 25 are mounted on shafts 32 arranged below and parallelto the guide rails 2. Fixed on the shafts 32, are pinions 33 meshing with a gear 34 of a train of gears driven by the drive shaft 19, whereby the cams 25 are continuously rotated. The rotation of the cams 25 is synchronized with the movements of the pusher slide 24 and conveyer chain 6 so that when the pusher moves forwardly, the flat portions of the cams 25 are rsubstantially parallel to the plane of the guideway 2 so as topermit the card or stencil to ride upon the cams, ln order to secure the cards against dropping between the cams 25, a pair of brackets 35 is arranged in position to support the ends of the card adjacent its middle portion. The cams 25 rota-te in the direction of the arrows, Fig. 4, and lift the card into the plane of the guideway 2 so as to permit the depending conveyer lingers 21 to engage the apertures 22.

In the form shown, the improved positioning device 8 includes a continuously ro-4 tatable horizontal shaft 36 journaled in the frame 1 and extending substantially parallel to the guide rails 2 directly above the path of the stencils. The shaft 36 is connected to the drive 19 by the train of gears shown at the right end of Fig. 1. Mounted onl the shaft 36, is a series of semi-circular flanges 37 spaced apart a distance slightly greater than the length of the card or stencil being operated upon. The flanges 37 form stops for engaging the forward' edges of the cards to accurately position them at certain stages in their travel. One of the stops holds the card in position for engaging the chain conveyer and the other stops position the cards for proper engagement with the gluing device 4 and pneumatic device 5. Also mounted on the shaft 36, are semicircular cams 38 adapted to engage the rear edges of the cards for urging them forwardly against the stops 37.- To prevent injury to the cards or stencils, the cams 38 are cushioned by helical springs 39 embracing the shaftj'36, as clearly shown in Fig. 6. The cams 38 are keyed to the shaft 36 so as to permit the yielding action of the cams. The end card, which is being acted upon by the lift-ing cams 25, .is urged forwardly into engagement with the adjacent stop 37 by an upright blade 40 pivotally mounted in 'the frame 1. The blade 40 is normally urged forwardly by a spring 41 and is arranged to be acted upon by the end of one of the cams 25 for retracting it into position for engaging the next card. f

The improved ejector 9 comprises a pair of cams 42 fixed on a shaft 43 journaled in a bracket 44 which is mounted on the frame 1. Fixed on the shaft 43, is a worm gear 45 meshing with another worm gear 46 on a shaft 47 which is geared to the drive shaft 19, whereby the ca1ns42 are continuously rotated in the direction of the arrows, Fig. 12.

The cams 42 are spaced apart a distance lslightlylcss than the lengtlrol a stencil 'so as to engage the end portions of the :stencil frame 3, thereby avoiding injury to the tissuev patch. In order to permit theendcard toadrop from the guideway when pressed downwardly by the cams 42, the outerguide rail k2 .is provided with a. yieldingportion 48 which supports the outer edge of the end card and which is adapted to swing downwardly to releasethe card under vthe pressure of the cams 42. t The yielding portion 48 is in.` the form of a stirrup, pivote-d to the bracket 44iby a pin 49. The stirrup 4S is nonmallywheld in `position forsupporting the car'd byV means of a spring 50 embracing the pin 49. A suitable receiving hopper or conveyor, not shown, may be placed below the cams 42`or1eceiving the ejected cards.

I In operation, the chain conveyer G travels in` a step-by-step: movement through :the action ot `the intermittently rotating `shaft 18. During each brief period of rest ofthe chain-.6,1m card is ted from the magazine 23 bythe pusherslide 24y which moves it onto the `lifting cams 25,. 4The cams 25 are continuously' rotated and lift the cardV intothe plane. of ythe guideway 2 for engagement with a pairof lugs 2l on the chain 6. The chain (Sgt-hen moves another step to carry the card ,into the guideway 2. The cards are fed along the guideway tobe operated upon by the various mechanisms and, when eaclr card reaches` the ejector mechanism, itis forced out of the guidewayby the cams 42. Vith this improved sheet handling mechanism, the articles are fed positively from one station to the next without` any possibili ity ofV amming. iT he apertures 22 serve for handling the stencil frames in the Various operations ot making stencils and also for handling in the machines in which the stencils are used. y i
