To all whmn it may concern:

Be it known that I, Cnsnum on Lmmosevics, a citizen of the United States and resident of New York, county of New York, State of New York, have invented certain new and useful Innrovements in Rotary Envelo -Machines, 0 which the following is a spec tion.

My invention relates to rotary envelop machines and the object is to im rove the construction of this class of mac ines, increase the capacit produce a more perfect and uniform'enve op preferably of standard Another object is to permit any size of envelop to be made without the use of special or separate machinerv to produce the same as is the case with other machines.

My invention consists in novel features and combinations for holding and picking up the envelop blanks off the revolving drum.

It also consists in novel means for turning and guniming the lapels.

It also consists in means for removing the envelo from the cylinder.

It also consists in novel means of removing the made-up envelop from the drying wheel.

Referring to the drawings, Figure 1 is an end elevation of my improved envelop machine; Fig. 2 is a side view of a portion of the same; Fig. 3 is a plan view of the same; and Fig. 4 is a section on line A--B, Fig. 3; this view also showing a mrtinl front elevation of the lower part 0 the machine and also the intermediate and finishing mechanism.

In the drawings 1 and 2 designate the frame of the machine suitably he d apart. The upper part of this frame supports the driviu" shaft 3 suitably jonrnulcd thereon. Unto ll is shaft is keyed the drum or cylindcr l by means of a hub 6 connected to the rim or outer body of the cylinder by the c lindcr heads or flanges 5. The head or hinge 5 supports the mr pumps, 8, 9, each ha vmg inlet or outlet pipes, 10, which lead from the pumps to the air or suction chamlior 11, two of which are formed oiposite each other in the face of the rim of l n: cylinders. 'lho pistons, 12, of each pump are operated by the grooved cam, 13, fastened to the frame 1 which is the upper part of the main frame of the machine. The said cam acts upon the pins, 14., fastened on the pistons 12 to cause reciprocations of the pistons for pumping purposes. The arrangement of these pistons is such that when one 15 moving outward the other is moving inward, and the object of this will be hereinafter described.

The air or suction chambers 11, formed in the face of the cylinder are in size equal to a folded envelop. The chambers are each covered with a plate, 15 having erforations as shown and suitabl held own in place. An interposed rub er rim, 16, is placed under each plate to insure tightness. The envelop blanks extend over these cham' bers and are held above and partly upon the cylinder by means of the resting plate, 19, resting and held on to a separating frame, 20, by means of the thumb-screws, 22. These screws also set and adjust the bla nit-holders, 23, which consist of the slotted arms, 23", having upright pins or arms, 23" to provide means for the eas manipulation of the blank holders 28. y means of the slots be tween the arms 23" and also by means of the upright pins or arms 23", the desired adjustment of the blank holders 23 can be secured. The actual points of contact between the blanks and the blank holders are at the bottom of the several pins or arms 23 as clearly shown in Fig. 4.

The separating frames are irovided with an opening somewhat larger t nm the size of the o )ening in the drum or cylinder, 4, and the s ape of this frame is similar to the envelop blank.

It will be seen that the separating frame at each end is connected to the cross heads, 25, 2o, by rods, 24, which pass through suitable bearings, 27, in tho i'rumc. The resting plate 1'.) is given on intermittent upwurd and downward movement through the medium of the gumwhcul, 28, which is keyed on shaftll. This 'cnr wheel 28 acts upon the spur whcnl, tllh hcycd on shaft 230, 'ournulcd in the l'runu: l, 2. The cross-bums, 2.3 21", being connected to the cranks, 31, on :lmll 30 lay nu-nus ol' the Hula, 3:2, nrc giron tln' ruquired movement when the shaft 30 1S rotated, being lifted and depressed once during each rotation thereof. The upper part, 1, ofthe frame, 1, 2, also supports the shaft 40. This shaft also supports the folder supporting frame, 44, to which are connected the lifters, 41, and turners, 42, 1n such a manner as to permit of their moving up and down upon the cylinder 1. This movement isetfected by the coil-springs, 43, (see lugs. 1 and 3.) Beneath this folder-supporting frame 44 are placed the rollers, 46, used for pressing down the turned over lapels. Th s roller is supported on the frame, 41 which is securely held on the frame of the machine, and pressed down upon the cylinder by the cam, 48, on shaft, 49, supported on the frame 1, see hig. 1. This shaft 49 is revolved by the gear pinion 50, keyed thereon, and into which meshes the intermittent teeth, 51, of the intermittent gear wheel, 51, keyed on the main shaft 3. 'l'he shaft 49 also supports the gumming roller, 52, the gumn mg surface, 49, thereof being supplied at intervals with the necessary gum by the distributing roller, 53, on the rocking arm, 54, fulcrunied on frame 1, 2, and intermittently operated by the cam 58, on the shaft 55, supported on the main movement from gear wheel, 56, acted upon by pinion, 50, see Fig. 1.

Beneath the gumming rollers is supported on the frame the angle late or blade 57 used to raise and fold e mmed lapel. And just underneath this his e is located the roller 54 for p down the gumnied lapel into place. This roller 54 is supported in sliding bearings and is also g ven the required tension by means of the Spl'1!]gS shown. Further underneath the cylinder is placed the second gumming device being similar in parts and operation to the one already described. The intermittent revolat-ion of the esumming roller 60 of this device is effect by the crank, 64, on a gear wheel 65, on the shaft, 66, suitably supported on the frame. The other end of this crank arm is connected to the gear wheel, 6?, on the shaft, 68, also supported on the frame. The intermitting teet of the wheel, 51, mesh into the gear wheel, 67, and revolve the parts in the same manner as the parts of the previous mechanism were revolved. Althe time the second grooming is being done and near the linishin of the some, the folded part of the cove op is expelled from oil the cylinder by the on pump which retained it because at this point the piston thereof has moved inward and interrupted the suction. lly cxpollin or ejecting the made up envelop in the a ovc manner the same is pcrmilh-d to turn and enter the chute, 00', edgeise no it fails. it in then caught up at the edge by the rollers, GT, 68*,

frame. This shaft 55 derives its.

the latter being mounted on shaft, 69, journaled on frame l.

When the envelop leaves the chute it drops into one of the compartments of the dryin wheel, 70, on shaft, 72, suitably sup. porte The shaft, 80, is supported in the frame 1, 2, and is driven by the belt, 81, passing over pulley, 82, see Fig. 1. The shaft 80 at a is rovided with a. cylinder, 80', having a cam aped groove, 86, into which enters the pin, 87, of the envelop delivery slide, 88, w 'ch is connected to the device for intermittently revolving the dr ing drum. This device consists of a roching arm, 89, suitably supported on shaft, 90, which is given an escapement action against one of the wings of the drying drum. This only takes place when the delivery mechanism has shoved oil one envelop. At the time this is being done the envelo passes over or before the rollers, 92 93 an 94, but before the envelop asses the roller 92 the upper lapel 1S tame and pressed down by the arm, 96, supported on the finishing bracket, 97, secure on the frame of the machine. This turning arm, 96, is shaped as shown in Fig. 2, the u per or flange portion, 98, is given the a e c and the part (Z is given a curve. Now w on the lapel strikes the an le 98 it is caused to be lifted and turned an then the curve completes the same, and the roller 94 finishes the ressi and manufacture of the envelo otion 15 wan to the rollers, 92,

93 an 94 through t e bevel wheel, 99, on shaft 80, meshing a bevel wheel on the axle, 100, having support in bracket, 97. This axle, 100, on the top has a large gear wheel which meshes into the inion, 102, on the axle of the roller, 94. T e other end of this roller has another pinion which meshes into an idler, 105 transmittin the motion to roller, 93, and thence to ro lot, 92, through the pinion, 106, see Fig. 2.

The operation of the machine herein described 15 as follows: The cnvelo blanks which can be of any number are p need nodcr the plate 19 and held in place by the corner pins or studs 23. The blanks now he upon the perforated plates of the suction chamber F o the pumps 8. The machine is now set in motion and as the shaft 3 revolvcs the intermittent wheel 28 will operate the late 19 and cause it to draw down the blnn ts upon the suction plate. Instantly this operation takes place, the pump 8 is operated u )0" by the cam, cousin" the piston thcrco to move outward. 'lu-n this takes place the um i will by suction draw down one of the dim s closely upon the sunlion plate. Now, as the cylinder 4 revolves in the direction of the arrow it will carry with it. the blank that has or is hold to it by the suction plate, and hold it thou-non lllllll the lapel turning and gun-lining devices have operated, to be hereinafter described. As the arms turn the blank on the cylinder lifters 41 will come in contact with the towers, 42, which will lift and turn over the end flaps upon the envelop proper; an

when these flaps are turned SllflltBlBllll? they are res-zed down closely by the rol er 41'. After the blank has had its end lapel turned over and pressed down, it is still meld on to the revolving drum by ried thereby to the gumming device, where one of the long lapels is gummed by the roller 52, intermittently operated upon by the gear \vheel'ol. In order to turn over this gummed lapel and press it down upon the turned over end lapels, the clingingl blank is turned by the drum against the b ade 5? which will raise the gummed lap1el as before described and as it turns over t e roller 5% will press it down closely u on the epvelop. The a-rtially finished blan still clings to the rum and is carried toward the second gumming device, where the interinittentl gununin roller will gum the loose lape The blan is now ready to be thrown off the cylinder, which is done at the time the second gurmning is taking place by the pump 8, and the pistons thereof moving inward through the cam which movement ex is the air and destroys the suction. The c jcct of expellin the blank when the unnning 1s takin p ace is to cause the finis ied envelop to fa edgewise into the chute 66 and between the travelin rollers, 67 68, when it is carried downwar until it. falls into one of the compartments of the drying cylinder 70. After the finished envelo has remained on the drving wheel a suita le length of time, it is thrown therefrom by the ejecting device. That portion which effects the result is the delivery slide, 88, operated by the cam 86' shoving a aiust the edge of one of the envclops on he drying wheel. At the time an envelop has been shoved outof the wheel, the cscapementdevice is operated for turning the wheel one vane forward. As the delivery slidc' 88 returns into place, the rock ing arm 89 is caused to turn so as to act upon one of the wheel vanes in such a manner as to move it forward. \Vbcn the envelop is being shoved oil the drying \vhccl it msscs the rollers 92. J3 and the loose lapcl already gunnncd and dricd will come in contact with the lurniup, lip or plate, Elli, which lifts this lnpcl and causes the Haunto be turned down. where it is caught up by the rollrr J4 which completely liuishcs the cnvclop for usc. When the cnvclop is being l'jct'lttl from tho drum by pump 8. the unnp b is holding a blank on to l a! cyliln vrs III the sunnmanner that the pump h caught up the above blank. .\t the moment a blank is caught up, an envelop is being expelled from the cylinder.
