To all whom it may com-em:

Be it known that I, CLIF'roN CHISHOLM, a I citizen of the United States, residing at Cleveland in the county of Cuyahoga and State of (lhio, have invented a certain new and useful Improvement in Address-Printing Machines, of which the followingds a full, clear, and exact description.

This invention relates to the kind of address printing machines in and by which address plates, stored in one container, are au-' tomatjically withdrawn therefrom, one by one, and the addresses on said several plates caused to be printed on envelops or the like. The present invention has more particularly to do with the means by which address plates are removed from storage and loaded into the machine, and are automaticallymoved through the machine so as to print their impressions on envelops or paper carried through the machine by other but synchronously acting mechanism and are finally collected for removal from the machine and returned to storage. And the invention consists in the combinations of parts by which those and other desired results are attained, as illustrated by the embodiment shown in the accompanying drawing and hereinafter described, the

essential novel features being pointed out definitely in the appended claims.

In the drawings, Figure 1 is a side elevation of a machine of the character specified,

in which the present invention is embodied;

Fig. 2 is a plan view of the said machine;

Fig. 3 is an end elevation with some parts broken away from the left end of Fig. 1; Fig. 4 is a sectional 'side elevation of said machine; Fig. 5 is a. sectional end View in the plane of line 5-5 on Fig. 4; Fig. 6 is a vertical section of a view in the plane of line 6-6 on Fig. 5; Fig. 7 is a longitudinal sectional view of a part of the main driving shaft and cam carrying brackets 80 and through parts adjacent thereto.

20 represents a hopper in which astack of address plates P are placed, and from which they are withdrawn, one by one, from thebottom of the stack by mechanism which carries them into printing relation with the envelops.

40 represents an address plate drawer into which said address plates are severally delivered directly they have been used for the above stated purpose. The plates P, between uses thereof, are stored or filed away in this drawer; which drawer likewise affords a convenient means for loading the plates which it contains into said plate hopper 20.

50 represents a rotatable cylindrical platen on which the envelopsare carried, after they are withdrawn from the hopper 10, into printing relation with the printing plates as the latter are being carried along beneath said platen by the mechanism provided for that purpose from the plate hopper.

The plate hopper 20 is a vertical rectangular tube made of thin metal which is fixed to and projects upward from a fixed block 21 that serves as the bottom of the hopper. In the front and rear walls of the hopper are the vertical slots 22 which are there to permit-the insertion into said hopper from the top thereof of one of the drawers 40 containing a stack of address plates, each of said drawers having on each side thereof a longitudinal rib which said slots accommodate as the drawer is moved into or from 1s there to permit the withdrawal of said drawer; and is necessary because otherwise the spring arm 46 could not be pulled out to release the address plates and leave them in the hopper when the drawer is withdrawn. nor could the drawer be withdrawn while the spring arms remain in the withdrawn position shown in Fig. 6 by dotted lines.

Two plate feeding belts 60, which may be made of thin metal tape or of any other suitable material. pass horizonally into said hopper just above the top of the bottom block 21.there being slots 24 in the right wall of the hopper to permit the belt and the feed lugs 61 thereon to pass; and there being also a slot 25 which extends entirely across the left wall of the hopper just above pl, CLEVELAND, OHIO, A. CORPORATION said block 21 through which said belts may also pass, and through which they may drag belt 60 at suitable intervals are the plate feeding lugs '61. Each belt is preferably formed with suitably placed holes 62 which are to receive the sprocket teeth carried by the sprocket wheels 63, 64. over which said belts run. The sprocket wheels 63 are fixed to an idling shaft 63. but the sprocket wheels 64 are fixed to the main driving shaft 70 and are driven thereby. On this shaft is a gear 71 that meshes with the gear 51 that is fixed to the shaft of the rotary platen 50 whereby the latter may be driven.

In the embodiment shown the conveyer belts are adapted to carry one plate to the printing position for each complete rotation of the sprocket wheel 64 on the drivine shaft and accordingly the lugs 61 are positioned a distance apart corresponding to the periphery of a sprocket wheel 64. The rotary platen 50, above mentioned, and envelop feeding mechanism which coacts with it. are adapted to feed two envelops for each rotation of this platen. and accordingly this platen makes a half rotation for each complete rotation of the sprocket. wheel 64.

' Therefore, the gear 51 on the shaft of the rotary platen has twice the diameter of the gear 71 on the driving shaft 70. i

i The mechanism shown for successively withdrawing the envelops from the bottom of the stack and feeding them about the platen into coaction with the plate and a pressure roll 7 5 on the shaft 70 is shown.

described. and claimed in my Patent No. 1285,6223, issued November 26. 1918. It will be convenient. however. to describe first this portion of the complete machine shown.

The successive withdrawal of envelops E from the bottom of the stack within the hopper 10 is effected by two feed arms 55. which are rotatable in unison with the platen 50 and are located one more or less closely adjacent each end thereof. Coaxial with the gear l'il are two sleeves 56 which are located adjacent opposite ends of the platen. These sleeves have a driving connection with the shaft, but are adjustable lengthwise thereof. Each feed arm 55 ispivoted to one of these is rotatable within a hanger 80, but hasno independent endwise movement with respect to said hanger. An annular shoulder 56 on sleeve 56 engages one face of said hanger while a nut 57 which screws onto said sleeve engages the other face of said hanger.

The two hangers 80, are suspended from and slidablenpon a transverse fixed bar 81, and they are respectively connected with the two parts 12. 13. of the envelop hopper. These hangers may be moved transversely on said bar toward and from the platen for adjustment. and the two parts 12, 13, of the envelop hopper move with them. but they are clamped fixedly to said bar in any desired position, when the machine is in operation. Each of these hangers carries a face cam 82 so shaped and placed that it. will engage the adjacent feed arm 55; and as the sleeve 56 is rotated with the shaft 51 said cams will rock said feed arms so as to carry time. the other ends of said arms will move away from one another so as to release any envelop which they may have been engaging. These armsv are .of such length that as they are carried up under the envelop hopper. the fingers thereon will go into the angular space between the lower envelop E and its down banging flap e. and will engage the bend which connects the flap with the envelop. The continued rotation of these arms will. therefore. withdraw the lowest envelop to the right from the hopper. and carry it around with. and insubstantial contact with the outer surface of the platen. beneath the lower edge of a guard late made of flexible rubber.--the function 0 this guard plate being to prevent the simultaneous withdrawal of more than one envelop. A fixed cover shield 52 adjacent to the platen helps to bend the envelop and hold it in substantial contact with the surface of the platen. There is also a pressure roll 53 which projectsthrongh a slot in said shield and is spring-pressed against the envelop. This roll is mounted in the lower end of a swinging frame 54. the said arms of which are pivoted at their upper ends to two brackets fastened to the right side of said shield; and this frame is under the influence of, the spring 51 which presses the roll against the envelop which is embracing the platen.

.-\s an envelope is being dragged along by the arms 55 in contact with the platen. its lower (front) face is brought into contact with the printing characters on the upper face of an address plate P which has been drawn from the bottom of the stack of address plates in the hopper 20, --the movement of the envelope and the printing plate being so timedb the described mechanism as to bring t is about. The printing plate and the envelop are ressed into contact as they pass together etween the platen and the pressure roll which is located just below the platenand may be fast to the shaft 70. The upper leg of each feed belt runs over a plurality of rollers 64 by which said feed belts are upheld, and are able to support the printing plate.

As each printing plate is moving from the hopper toward the platen it passes under an inking roll 93 which lies directly over an idler roll 62 and is such distance therefrom that the printing roll will of necessity ink the characters on the upper side of the address plate. The inking roll is mounted in a swinging frame, the side members 90 of which are hung on the platen shaft and project to the right therefrom. An ink holding roll 91 is also mounted on said swinging frame, and so also is an ink distributing roll 92, which lies between and in contact with the ink holding roll and the inking roll so as to transfer ink from one to the other. The particular construction and disposition of the type inking rolls is not material to the present invention and any suitable inkin mechanism may be employed. The enve ops carried along with the platen by the feed arms 55, and the printing plates carried along by the feed belts pass between the platen and the roller 75, and are properly pressedagainst one another so as to cause the address on the plate to be printed on the envelop. The shield plate 52 is cut away below the platen in itsmiddle portion so that the address plates may print the envelops through this opening, the sides of this shield plate however, remain and always support the end portions of the envelops, while they are being printed. The lower part 52 of this shield plate lies at the left of the platen and inclines downward as shown, the envelops after being printed on slide down this inclined continuation 52 of the shield plate until the envelop drops onto the envelop receivin platform 30, or more particularly onto t \e top envelop of the pile of envelops on said platform. The envelops as they slide down this inclined plate 52 slide between guide bars 16, which overlie plate 52, said guide bars being connected respectively to the two hangers so that they will always be at the required distance apart, because when the hangers are moved lengthwise of the shaft as and for the purpose stated, these guide bars 16 will be similarly moved.

Each printing plate as it emerges from between the platen and the pressure roll 75 falls into a curved chute down which it falls onto a rubber bufl'er plate 112, and

sheet metal bent to-form two sides and a top as shown particularly in Fig. 5. Each of these drawers has two outwardly extended ribs 43 upon which the drawer is supported upon the fixed brackets 120, and

in operative position to receive the address.

plates in the manner before stated. Inwardly bent longitudinal ribs 41 are pref-- erably formed lengthwise of thisdrawer, and they are intended to go into corresponding notches p in the sides of the address plates. Two other corresponding inwardly directed ribs 42 are provided to go into two other notches p in the sides of the address plates, so that said address plates will be held upright therein. In the sides of the drawer are the bevel-ended spring detents 44 which prevent any backward movement of one of the plates after the packer has pushed it past the detent jaws.

Extending part way across what is the rlght hand end of this drawer when it is in the machine, a plate retaining arm 46 projects, which arm is connected with a long flat spring 45 fastened to the outer face of the top side of this drawer. This is to prevent the plates from dropping out of this end of the drawer when the drawer is held with that end down as it must be when one loads the hopper 20. To load the hopper, the drawer filled with plates is put vertical 1y downward into the hopper, with the said right hand end thereof down. When the plates are resting on the bottom of the hopper one takes hold of the knob. on the outer face of the spring 45 and draws it outward.I thereby withdrawing arm 46 from beneath the address plates. While it is in this position the drawer is withdrawn from the hopper and the plates are left therein. The spr1ng45 which is then extended outward from the drawer is movable in the vertical slot 23 in the right side of said hopper.

The envelop hopper 10 is formed of two upright angle plates 12, 13, each of which is connected with a triangular bottom plate 14. This hopper occupies a position above and to the left of and close to the platen cylinder. But the two above. mentioned parts 12 and 13 of the envelop hopper are adjustable toward and away from each other, and toward and away from said platen cylinder in order that the hopper may hold envelops from said hopper.

{ Each of these tw of various sizes in proper relation to the platen cylinderand to the means for successively withdrawing the bottom envelop 0 members 12,13, which comprise the envelop hopper is slidably mounted on a rod 83 that it fixed to and extends horizontally to the left from the associated hangers. These hopper members may be moved along this rod to-positions de termined by the width of the envelop.

Now, when it has been determined what length envelops are to be addressed the two hangers 80 are moved to what extent may be necessary toward and away from each other. As they so move the front and rear members 12 and 13 0f the hopper are caused to move toward or from each other until they occupy a position such that the hopper is adapted to hold the envelops to be ad-- dressed. When the hopper members are in this position, the feed arms will likewise be in a proper position to co-operate with these particular envelops because the sleeves which carry these feed arms and the cams which operate these feed arms are mounted on the hangers and move with them.

In order that the envelop hopper members shall remain upright as they are adjusted, a rectangular frame is mounted to slide horizontally on the fixed framework of the machine. This frame includes side members 120', and twotransverse members 121. A U-shaped bar 112 fixed to each hopper section extends to the left therefrom, and rests upon the two transverse bars 121.

The platform 30 upon which the addressed envelops are delivered is mounted to slide up and down upon the two fixed guide bars 127. It has projecting to the right therefrom two bracket arms 31 each of which is connected to the lower end of two upwardly extended bars 32 which are located adjacent to the front and rear sides of the envelop hopper; and are provided with a plurality of inclined notches 33.

There is a follower 35 provided for resting upon a pack of envelops in the hopper 10. This follower is fixed to a bar 36 which extends forward and backward horizontally to the right of the hopper, and it has twoarms 37 which extend to the left, and each arm has an outwardly projecting pin 38. lVhcn a stack of envelops are put into the hopper this follower is placed upon the top of the stack. and then the two vertical bars are hung upon these outwardly projecting pins 38. The particular notch 33 in the said bars which is to engage with these studs depends of course upon the height of the pile of envelops. because these arms support the platform 30 and this platform should be in a position that the envelops will go onto it nicely as they are discharged from the inclined plates. Therefore, regardless of how high a stack of envelops is put in hopper 10, the platform 30 being adjusted into proper position at the beginning of the operation of printing this stack of envelops will move down just as fast as the height of the pile of envelops in hopper 10 is lessened, so that always the top envelop onthe platform 30 will be in proper relation to receive the envelop which is being delivered from the inclined plates.

There is a three-sided shield 139 which embraces the platform on the front, rear and left sides thereof, and this serves to keep any/of the envelops from falling off of the platform. This shield which is made of two independent angle irons is secured to four rods, 131', 132, two'of which, 131,'are pivotally hung at their upper ends from the U- shaped bar 122. The other two rods 132 have springclips at their upper ends for engagement with said bar, and serve to lock said shield in operative position. Obviously, when the hop r members are moved to right or left to adapt the hopper for envelops of different sizes, the shield will be correspondingly adjusted with respect to the platform. When it is desired to remove a stack of addressed envelops from platform 30, one pulls the rods 32 loose from the bar. and swings the shield to the left out of the way. Unless the envelops together have a width greater than one half the circumference of the platen 50, two envelops will be withdrawn from hopper 10 at each revolution of the platen. The feed lugs on the address plate feeding belts are so positioned that they will feed two address plates toward the printing position during each revolution of said platen and in such wise as to meet the two envelops.

However, if the width of the envelop is I greater than one half of the circumference 1 of the platen roll, then only one envelop will be withdrawn from the hopper during each revolution of said platen, because when, say, (referring to Fig. 4). the right end of two feed arms as shown in this figure are en- 1 gaging one of these wide envelops, and carrying it around, the feed fingers at the other end of these arms will go beneath the same envelop instead of engaging the flap of the next envelop above i Therefore, while only one envelop is be ing fed during each revolution of the platen it is desirable to have only one printing plate removed from the plate hopper during a revolution of the platen. To effect this result automaticall there are two side frame members 140, w ich are hung upon the driving shaft 70 and extend to the right therefrom; and in their rear ends is mounted the shaft in which the two right hand belt sprockets 63 are fixed. The frame which carries the ink holding, ink distributing, and inking rolls is connected with these" two side frame members by links 94 which are adjustable in. length, so that whichever position this frame may occupy the inking rollers will be in roper working relation to the feed belts. 'he several belt supporting rollers 64, are mounted on this rocking frame and so is the pressure roller 62 beneath the inkin roll.

The right end of t is frame is under the influence of a spring 66 tending to swing it up as far as it can go,- that is to say, until further upward movement is prevented by the engagement of said side frame members with certain fixed stops, 141. When the frame is in this position the belts are in position to withdraw the bottom late from the hopper whenever a feeding ug enters said hopper. Mounted on the right end of this swinging frame above the sprockets is a shaft 142 on which is a cam 143, and to which a driving sprocket 144 is fixed. A sprocket belt 146 transmits the rotary motlon to the shaft from a sprocket 147 fixed to the driving shaft 70, the latter sprocket being one half the diameter of sprocket 144, whereby the latter and its shaft will rotate half as fast as the driving shaft.

Mounted on a fixture is a rocking frame 150, which includes two arms, one of which carries an idler roll 153 that may or may not engage the cam 143. A spring 154 holds the frame normally in position such as prevents the roll 153 from being touched by the cam. But by an adjusting screw 149 this frame may be rocked to a position such that the cam will engage said roll 153. Therefore, during each rotation of said cam shaft, the entire frame will be rocked down in opposition to the spring 66; and when the frame is down, the belts will be so depressed that the lugs 61 thereon will pass through the late hopper but will not strike the lowest p ate. Before the next feed lug comes along the rotation of the cam will permit the spring 66 to swing the frame upward, tothe position shown such that the lugs 61 will engage an address plate. Therefore alternate feeding lugs will engage and withdraw an address late, while the intermediate lugs will pass beneath and out of contact with the lowest address plate.
