The invention Will be best understood by referjournaled in the frame ofthe machine, and upon ence to the' accompanying drawings, forming a .which is mountedfpower driven feed roll 34 norpart of this specication, and in which: mally having frictional Contact withY an upper Fig. 1 is a side elevational view of a preferred idle rollerl 35 so arranged that paper web 30 is embodiment -of the machine embodyingthe infed forwardly. After passing between rollers 34 105 vention, vwith the. engaging yclutch mechanism and 35, the paperweb preferably passes around, omitted to more clearly illustrate the construcin suspending manner, a-oating spool 36 which OII; serves to vmaintain the kweb in smoothcondition, Fig. 2 is a top plan view of the apparatus shown and thereafter the paper passes upwardly and in Fig. 1; Y Y l y `thence downwardlyL through a creasing device 110 37, which is not shown in detail because individually used heretofore, and by means of which the lateral marginal portions of the web are creased to later form creased side aps 38 after serrations are cut in the marginal portions. The web is then carried between trimming rollers 39 and 40, which are geared together, the latter being mounted upon transverse shaft/41 which carries bevel pinion 42 driven by a bevel pinion 43 upon shaft 24. Cutting rollers 39 and 40 serve to cut out the intermediate portions or serrations between the successive side flaps 38, and thereafter web 30 is carried between a type printing roller 44 and lower press roller 45. Type printing roller 44 carries a cylindrical type holding plate or form for impressing any desired printed matter upon the surface of the web which is later to constitute the exterior of the finished envelope.

Press roller 45 is mounted upon transverse shaft 46 suitably journaled in side plates 47. Splined upon drive shaft 16 but slidably mounted with clutch member y18, is pinion 48 which meshes with an idle pinion 49, which in turn is in mesh with gear 50 loosely mounted on shaft 46 and having a hub portion adapted to form a jaw clutch in cooperation `with clutch member 51 keyed to shaft 46. The upper type printing roller 44 is carried by shaft 52, upon which is mounted gear 53 meshingwith a similar gear mounted upon the lower shaft 46, whereby type printing roller 44 and pressure roller 45 travel at uniform speed in opposite directions.

Shaft 52 is preferably journaled in a hinged frame assembly adapted to be swung on shafts 54 and 55. This assembly comprises a side plate 56as shown in Fig. 1, and a corresponding side plate 57 disposed on the opposite side of the machine. This arrangement is desirable for resetting the type in roller 44, and similarly the inking mechanism assembly 58 is swingably mounted on pivot 59 and a corresponding pivot on the opposite side of the machine, and may be held in any desired elevated positionby means of wing nut 60 threaded on a stud slidable in arcuate slot 62. The inking mechanism, for applying ink to the type printing roller 44, need not be described in detail because not separately novel and is subject to considerable alteration in view of the factV that the only purpqe is to apply ink to the type printing roller. In the embodiment'shown, pinion 62 is secured to a transverse shaft upon which is also mounted gear 63, which is in mesh with gear 64 mounted on shaft 65, which carries gear 66 driven by gear 53. Pinion 62 is adapted to drive gear 67 carrying van offset crank pin 68, to which is connected one'end of pitman 69, connected at the opposite end to rock arm 70 loosely mounted on shaft 72, which is adapted to intermittently engage rotary ratchet 73 keyed to shaft 71. Shaft 7l carries roller 74 which supplies ink from an ink container 75 lto a plurality of ink ing rolls 76 through an intermediary roller 77. In this manner the ink is supplied from the reservoir and evenly distributed before application to the type printing roller 44, as is understood. Inking rollers 78 and 79 are in direct contact with the typel printing roll 44 and are driven by frictional contact with an intermediate roller 80, which in turn is driven by frictional engagement with the two lower pairs of rollers 76.

Beyond rollers 44 and 45 they web 30 travels upon table 8l which is suitably recessed transversely for the various rollers and is next engaged by pro- 3 carrying pinion 84, in mesh with drive pinion 85. Upper pressure roller 86 is preferably provided with a resilient surface and is in frictional contact with 1oller82. Preferably, rollers 82 and 86 are geared together by means of gears 87 and 88, respectively. The paper web 30 next passes between a lower paste applying roller 89 and upper pressure roller 90. Roller 89 is mounted upon shaft 91, which carries bevel pinion 92 driven by bevel gear 93, and shaft 91 carries at the opposite end gear 94 which meshes with gear 95 mounted on the shaft 96, which carries roller 90. Paste applying roller 89 is provided with a segmental portion 97 on the surface, which is formed of an outline to correspond to the portion of the under surface of web 30 that is intended to receive paste for adhesion of the lining paper later applied, This segmental portion may be of any desired outline to suit different types of envelopes, but in the present embodiment, consists of portion' 98l extending transversely of the web to vapply the transverse adhesive 99 shown in Fig. 7, and the segmentsA 97 extend circumferentially on roller 89 to provide longitudinal adhesive 100 shown in Fig. 7, andv similar 'adhesive on the opposite side. Y

Paste applying roller 101 is immersed in paste tank 102, supporteclby cross rails 103, and preferably is provided with an adjustable scraping plate 104 interiorly mounted. It will be noted that roller 101 does not directly contact with the bo'dy portion of roller 89, but only with the segmental portions 97 and 98 which apply the corresponding outline' of adhesive on' the under surface of web 30. Roller 101 is mounted upon shaft 105, which carries gear 106, driven by gear 94. The next operative step consists in applying the patches of lining paper to the under surface of Aweb 30 for adhesion thereto by means of the paste applied as just described, and is carried out as follows.

Suspended in the lower portion of the machine, by means of oppositely disposed brackets 107, is a roll of lining paper 108. This lining paper 1s preferably of lighter stock than the web which forms the envelope proper, and generally carries an ornamental design. Upon being unwound from the roll 108, the lining web, which to distinguish from the envelope web 30 will be designated as the liningstrip 109, passes between feeding roller 110 mounted on shaft 111 which pref erably carries a cone pulley 112 for regulating speed, driven by belt 113 passing over a corresponding pulley 114 mounted on shaft 105. Roller 110 is maintained in frictional contact with roller 115 and is preferably geared thereto as shown.v By this manner, the lining strip 109 is unwound from the reel and hangs in a bight as shown, and then extends upwardly between shoe plate 116 and leaf spring member 117 moiuited' in block 118 and adapted to lightly bear against the paper strip so as to merely yieldingly maintain the same in position. Thereafter lining strip "109 passes between cutting roller 119 and complementary roller 120. Roller 120 is mounted upon transverse shaft 121, which carries gear 122 adapted to mesh with gear 123 secured to transverse shaft 124, which carries roller 125, and the opposite end of shaft 124 carries pinion 126 driven by bevel gear 127. Severing roller 119 carries gear 128, which in turn is driven byl gear 122 mounted on shaft 121, causing rollers 119 and 120 to rotate in opposite directions at uniform speed.

Mounted upon the periphery of roller 119 and pelling power driven roller 82 secured to shaft suitably held in a groove, is a severing knife 129 adapted to transversely sever the liningstrip 109 for the desired :length for -each envelope, and complementary roller 120 is provided with a cor responding groove 130 to complete. the severing operation. This operation serves to sever the lining strip 109 into individual lining patches bstantially on the lines 131, as shown in Fig. 6, or in accordance with any modifiedxshape that may be desired. It willtbe understood that rollers 119 and 120 continuously operate, and after a severing operation the paper is carried forward a slight distance by means of roller portion 132 which follows the knife 129. This serves to present a sufficient edge portion for the next following gripping and feeding operation. Inasmuch as the lining patches are spaced apart upon the under side of the paper web, it is necessary to provide intervals in the lining feed, and therefore a suitable recess 133 is provided in roller 1.19, dure ing the passage of which the lining feed is interrupted. As shoulder 134 on` roller 119 comes in contact with the surface of roller 120 the projectingedge of theliner 109 is engaged and the feed continued between rollers 120 and 125, during which operation the severed-lining patch is carried through an arcuate ypath in guided contact with guide shoe 135. This operation serves to bring the lining patch in position for contactJ with the under surface of the paper web 30 and in registry with the portions to which paste or adhesive has been applied as described, and the patch is then sealed to the web in passage between rollers 125 and upper pressure roller 136. Rollers 125 and 136 are preferably geared together by means of gears 123 and 137, respectively.

At this point the envelope web which has had printed matter applied,xif desired, yto the lupper surface which ultimately formsthe outer surface of the finished envelope, has a lining patch ad-v hered to the under surface of 'the web, or the side which is disposed on the interior of the printed envelope. Also, the side marginal .edges are trimmed or serrated to provide the side sealing flaps33. The mechanisms which perform `the subsequent operations of applying an adhesive to the side flaps, indenting and severing the envelope web transversely vto provide envelope blanks, trimming ofi the corners of the severed blanks, creasing and forming the hinged fold to bring the back and front portions together, and

applying an adhesive to the upper closure flap, are not individually novel and is referred to in the present description to complete the disclosure and mode of operation; Therefore, it will be unnecessary to describe this portion of rthe appa-I ratus in detail.

After passing between rollers 125 and 136 the side flaps 38 are turned under by means of fold.-

ing `wires 137 and adhesive is applied to these.

flaps by paste applying roller 138, carrying the suitable segmental portions 139 which register with the flaps 38. Segments 139 receive paste from the paste supplying roller 140, themajor portion of which is immersed in paste receptacle 141. Roller 138 is mounted upon shaft 142 which carries bevel pinion 143 driven by bevel gear 144, and on the opposite end is provided with gear 145 meshing with gear 146 which is mounted upon shaft 147 carrying theupper pressure roller. 148. Similarly, paste supplying roller 140, whichI is mounted on shaft 149, is driven by gear 150 likewise mounted on shaft 149'and adapted to mesh with gear 145. The mechanism for completing the envelope is not individually rnovel and includes two transverse power driven shafts 151 and 152.

In these subsequent operations the web, 1 as shown in'Fig. 5 with the lining patches applied thereto, is severed transversely to provide the envelope blank shown in Fig. 7. These blanks are then4 successively folded, as shown in Fig. 8,. bringing the back portion in contact with the side flaps 38 to which the back portion is sealed,y and adhesive 153 is applied to the top closure flap. After the completedy envelopes are formed they are carried from ythegmachine by endless chain conveyors 154. I v
