Application filed May 3,

To all whom, t may cof/cera Be it known that I, VILLIAM E. Pnunrcn, a citizen of the United "States, residingy at Buffalo, in the county o'f Erie and State of New York, lhaveinvented a new 'and useful Improvement in Mechanism for Feeding Stencils or AnalogousArticles, of which the following is a specification.

This invention relates to'mechani'sms for feeding sheets or similar articles, land more particularly to mechanisms for feeding stencils in connection with addressing machines or the like.

In addressing machines las heretofore made, the stencils are arranged in suitable frames or individual holders or containers which protect the stencils from injury which might be caused by the partsof the machine and by contact of `the stencils" with each other, and which cooperate with parts of :the machine to effect the feeding of the frames and stencils to a printing or inking mechanism. Consequently vwhen a large number of stencils is used, a large amount of space'is occupied by the stencil frames and also considerable time is required to place ythe stencils into the frames.

One of the obje-cts of this invention is toprovide a feed mechanism for yfeeding stencils w'hich is capable of handling the stencils without the usual stencilframes.

Other objects of this inventionare to ypro-l vide a mechanism of this kind whichis V so constructed that the individual stencils may be removed from the stack without rubbing the stencils vagainst each other; also lto provide means of improved .construction for feeding the stencils from the stack to the Vprinting mechanism; also to provide improved means for depositing thestencils in a magazine or stack after the 'saine have passed through the machine; also to improve the construction of machines ofithis kind in` other respects hereinafter specified. f

The stencil feeding mechanism forming Figs. 21 and- 22 are fragmentary longitul thesubject matter of this invention may vbe applied to any desired printing or `addressingmachine, and is shown in the drawings as forming a part of an addressing' machine of well known type.` This addressing machine lhas a Y"frame including a -substantialh7 horizontal frame member A, and a pair oi upright frame members A which support a table B. The frame members A are provided with bearings for a drive shaft C which receives power fro-1n a gear C. riChe machine includes a feeding` mechanism (not shown) for the articles to be addressed, and' an ink-applying mechanism of which only an ink-applying roller D is shown in. Fig. l. rllhe addressing machine shown also includes a movable platen E actuated by suitable mechanism mounted on the drive shaft C. All of these parts may be of any suitableor usual construction, and of themselves constitute no part of this invention.

X represents the stencils which may be of any usual or suitable type and which are generallymade of paper or other relatively thin material and which are perforated in the usual manner to permit the ink from the ink-applying troller D to pass through the perforations to the articles to be addressed or printed. Since these perforations are irregular in form and may form projecting parts on the stencils which may engage the perforated portions or projections of an adjacent stencil` it has been heretofore considered desirable to confine each stencil in an individual frame or holder and thus keep the stencils out of engagement with each other.

By means of my stencil feeding nism, the stencils can be fed from a stack of stencils in which the stencils lie face to face7 since the parts of my feedingmechanism are so constructed that the stencils are separated from the stack in such a manner that the perforated portions of one stencil will not engage or interlock with the perforated portion of another stencil. This is accomplished by moving each stencil away from an adjacent stencil in a direction substantially perpendicularto the face of the stencilg thus avoiding' the sliding or rubbing of a stencil while in contact with another stencil. After the stencil has been 'com pletely separated from an adjacent stencil. the stencil may be moved any desi rection.

ln the embociment of t 1e in the drawings t-ie stencis to be fed are arA ranged in .in si tical guideway formed by guide members 2G and 2 y the lowerends of which are secured to a table o1' pla te 2S secured to the table B of the machine. This mechaplate 28, in the construction-shown. s formed integral with a frame member 29 on which many of the parts of the stencil feeding mechanism are mounted. The stencils in the construction shown, are removed from the'bottom of the magazine and this isA accomplishedV by'rst completely separating the lowest or bottom stencil from the other .Stencils of the stack .in the nilasazilfifw lfiasia ln the mechanism, shown in the drawings, the first step in separatingthe lowermost stencil from the other stencils of the stack consists in drawing; one edge of the lowermost stencil downwardly away from the next stencil. In thev particular construction shown for this purpose, this is accomplished by means of a suction device or cup 30 which is preferably made of flexible material such as rubber, and is -carranged at the upper end of a suction pipe 31. The lower end of the suction pipe is connected preferably bymcans of a flexible tube 32 with a suction cylinder 33 supported on the frame 29 and having` a piston 3e arrangedI therein. The cylinder 33 is also provided with an opening 35 adapted to be closed by a suitable valve 36 when it is desired to create in the cylinder a partial vacuum or suction, and which may be opened to the atmosphere when it is desired to break the partial vacuum or suction in the cylinder. The piston 34 may be reciprocated by any suitable means, being connected in the construction shown by means of a connecting rod 37 with a crank 38 secured on the drive shaft C. Any other means for produc ing' thel necessary suction may be provided.

ln order to move the suction device upwardly into engagement with the lowermcst stencil and to move the same downwardly for withdrawing; `a part of the stencil from engagement with anadj acent stencil, the following; mechanism is preferably employed.

The suction tube 3l is secured to a guide member 4l() slidably mounted in brackets lll and l2 arranged on the frame member 29. Fig. 9, the guide member 40 being provided with an offset portion 48 to which the suction tubel is secured by means of nuts da or the like. This guide member insures a vertical movement of the suction memberso that that part of the stencil engaged thereby will be moved away from the adjacent stencil substantially in a direction perpendicular to the faces of these stencils. The reciprocation of the guide member and suction device in the construction shown accomplished by means of a bell crank lever pivoted at 4 and having arm 47% the end of wh l1 i .ses in bifurcated no tion of the i member e0. Another 14;9 of the hell crank lever is provided adjacent to its end with an antifriction roller 50 which held in engagement with a cwi 5l, by any suitable means, such for example b v a spring; 52, The cam 5l is secured on an upright shaft 53 and the face ol" the cam 5l 'which ei'lgages the roller 50 is so forme-d as to produce the desired movement of the bell crank lever and the suction device.

The opening and closing of the passa ge in the cylinder 33 is preferably controlled by means of a cam 55 arranged on a second upright shaft 56 and engaging; a roller 57 secured on a lever -pivoted on a bracket 59,

las 'shown in Fig. IO. The valve 36 is con- The suction device is then moved down' wardly carrying the iront edge ot the stencil with it and after an interval of time the 'suction is broken so that 'the stencil is released. from the suction device as shown in Fig. i2.

After an edge of the lowermost stencil has been drawn downwardly, the complete separation of the lowermost stencil from the Vstack is eil'ected. This is accomplished in the lcoi'istruction shown by means of a pair of rotary disks and 66 which are mounted respectivelilv at the 'upper ends of the vertical shafts and 5 6 and which revolve in opposite directions 'as indicated by the arrows in Figs. 3 and 4; These shafts are suit-ably journaled in the frame lmember 29 and may be driven from the drive shaft C in any desired manner, for example, by means of a gear 68 mounted l-on the drive shaft C and meshing' with gears '69 and 70 secured on the shafts 53 and 56. The

disks

65 and 66 are arranged adjacent to each other in such a tively to the movement of the suction devicel that the lips 7 3 of the disks will pass between the lower-most stencil Aand the other stencils,

ot the stack from opposite sidesof the stencil. after the `iront edge of the lowest stencil has been drawn downwardly by the suction device. The iur-ther` rotation of Ithe disks causes the lips 7 3 to effect a separation 'of the Ventire stencil from the other stencils 4of the stack by causing parts of the lowest stencil to pass through the slots 72 during the rotation ot the disks. This causes thelowest stencil to be separated from the adjacent stencil without movement of this stencil relatively to the adjacent stencil in a direction to cause interlocking.y or catching of the perforated portions of the stencils and also ensures a positive and complete separation of the two'stencils, even if the ink on the stencils 'tends to cause them to stick together. TheV suction device actson the end portions of A'thefstencils'which are not coated with ink, while the positively 'acting "disks are relied positioned beneath the stack sup porting upon to separate those parts of the stencils which might tend to adhere toeacli other. Then the `'disks are in thepositions shownr in Figs. 2 and 4C, the lowermost stencilis bei low the disks and the `other stencils of the stack rest upon the upper faces oit the disks.- ritterv suction in the suction device is broken, the lowermost stencil is ready tobe removed from its position beneath the stack oit sten*-v` cils.` ln case it is 'found desirable not to depend solely upony the suction device to holdl the lowermost stencil against lengthwise movement while passing through the slots 72 in., the disks, an additional holding' device foi the lstencil may be provided.` This holding device, inthe construction shown,'incl'udes a holding* lingr 75 secured to the upper'end ot' a lever 76 pivoted at 77 in the trame inemberk29.v The lower end of this lever is preferably provided with a roller 79 engaging the 'upper face of a cam 80, alsomounted -upon the upright shaft 53. ln order to hold the roller in engagement with the` face of the cam 80., a spring 6l is preferably employedl" The face of this cam is `so formed that after the suction device has pulled downwardly the front edge of the lowermost stencil, the 'holding linger l7will move downwardly in u an arc of a circleflirom the position shown iii" Fig. 13 'tothe positionshown in Fig. 12', and press a part of the tront edgev of the stencil against ,the plate or table 28. Theholding finger will thusprevent rearward movement ot the stencildue tothe friction between the" stencil and the separating

disks

65 and 66, and the cam again raises the holding`-` linger 75 out of engagementwith the stencil when the stencil isv ready to bevmoved forwardly `from Aits position underneaththe stack. Any'` other means io'rfpositively holding' the sten- 'cil against rearward movement may be provided, or, it desired, rthese holding, means may be omitted. v l i In order to move the `stencils "to the printing;.meclninismaiter they have been separated trom the stack and aiter they are motion b v lineair-1y ot a reciprocatory ,sliding This bar is provided with an' enbar 90. larged portion orplate 91. which is adapted to pass over the lowermost stencil and 'is pro-A vided its rear end with a suitable stencil- 'cgaging device which. may be in the form s 65 and 66 upon the plate 26, the ollowot a 'sprii'igg'member 92 secured'tothe plate 9i and :held rn 'place by means citaprotect-"f130 frames into which the stencils are inserted. r1`his effects a very 'considerable saving, in the rst place, of the cost of the frames themselves, and in the second place, of the amount of storage space required for the stencils. rl`he machine described is more efficient to operate than machines in which the stencils are arranged in holders since a greater number of stencils may be placed in the magazine 125 at one time. rlhe machine described has the advantage of separating adjacent stencils without rubbing the surfaces of the stencils relatively to each other, this being accomplished by withdrawing a stencil from an adjacent stencil in a direction substantially at right angles to the surfaces of the stencils. Itis also desirable to separate a stencil from an adjacent stencil by successively separating different portions thereof, this being accomplished in the construction described, by first separating an end of the stencil and then by having the lips separate the remaining portions by a gradual movement in the general direction of the length of the stencils. The machine described also has the advantage of operating mainly on the edge portions of the stencil, thus avoiding injury to the perforated portions thereof and avoiding the rubbing of ink from the perforated portion to other portions of the stencils, the middle or perforated portions being separated from an adjacent stencil due to the fact that the disks enter between the two stencils. The machine described is rapid and efficient in its operation and simple and economical in construction.

While the machine embodying the invention has been described as adapted particularly for feeding stencils in connection with an addressing machine, yet it will be understood that it is not intended to limit the feeding mechanism to this use, since the mechanism shown may be used equally well in connection with the feeding of sheets or other flat articles. lin those claims not particularly limited to stencils, it is understood that the mechanism recited may be used for feeding sheets or analogous articles other than stencils.
