erence being had tothe accompanying drawing.
In the manufacture of window envelops 1t 1s customary to progress a. continuous web containing window apertures and fr9ml which envelop blanks are to be stamped out= in proper relation to each window aperture. Simultaneously a so-called patch web of- -transparent material is progressed, gummed and cut into patches which are thereupon affixed one to each window aperture ofthe progressing envelop web. Difficulty has been experienced in properly correlating the movement of the patch web and the envelop web to bring the patches successively into proper relation to the apertures in the envelop web. For this purpose mechanism has heretofore been devised, according to which the travel of the patches severed from the web is more rapid than that of the slowly advancing patch web, in order to compensate for the fact thatthe envelop web must travel faster'- than the patch web.
I have discove'red that these difficulties may be better overcome by imparting to the patch web an intermittent motion by means of which it, as Well as the patch cut from it, is advanced at proper intervals with a rapidity equal to that of the envelop web, and yet it is allowed to dwell motionless during the intermediate intervalswhile the envelop web is progressing sufficiently to bring another window into proper juxtaposition with the terminal patch which is to'be cut from the patch web.
rl`he accompanying drawing illustrates my mechanism in the form of a sectional View.
The envelop web 1, is continuously progressed as it passes between and is supported by the paired rollers 2, 3, and 4, 5. As it passes through the rollers 2, 3.window aperturl'es 6, 6, are cut in the web at proper interva s.
Patch roll 7, is properly supported as shown, and from it the patch web 8, passes under a tension roll 9, hung upon a pivoted lever 10, limited by a stop 11. Thence the. patch web is led around the rods 12, 13, and
Of these the lower roll 16, contains protecting gumming surfaces of appropriate conformation, which, as the roll rotates, have gum applied to their edges by the roller 18, rotating half-immersed in the gum receptacle 20, and which surfaces impress their gum upon the patch web as it passes. After passing around the roll 15, and receiving gum from the roll 16, the patch web passes betweel'iylthe paired driving rolls 21, and 22, and thence between the rolls 23, and 5, which lare geared for common rotation, and which carry on their respective surfaces shearing knives, whereby the terminal portion of the patch web, already gummed, maar be sheared off to form a patch, and immediately advanced into adhesive contact with the window aperture of the envelop web.
The rotation of the rolls 2, 3, 4, 5, and 23, is continuous and at the rate at which the envelop Webis tobe progressed. The rotation of the other rolls which I have described is intermittent, and this intermittent motion is accomplished ,as follows:
The roll 5, has pivoted to it the connecting rod 30, the extremity of whichis pivoted to the pawling arm 31, pivoted on shaft 32, and carrying a pawl 33, which engages a ratchet wheel 34, set on the shaft 32,' in fixed relation to the gear wheel 35, which meshes with a similar pinion on the shaft of roll 22. Roll 22, is geared. to roll 15, by means of the sprocket chain 37, and by means of this connection the gumming rolls are caused to intermittently rotate iu the same manner as is roll 22, and its twin roll 21.
In operation the patch web, having passed around the rolls and 'mechanisms mentioned, and having gum properly applied to its surface,- is advanced at a speed corresponding to that of the envelop web, until its forward edge is in contact withthe envelop web just where that web is passing between the rolls 4, and 5. Thereupon -the knives of the rolls 23, and 5, sever the terminal portion of-the patch web, creating a patch which continues to -travel along with and at the same speed as the envelop web the movement of both being dependent upon the rotation of the rolls 4, and 5, by which 'it is pressed in contact with and caused to adhere to said envelop web over vone of the window apertures. After the severance of the patch, the connections andgearlng which I have 4described eifecta total intermission of the rotation of the rolls 141, to the paired gumming rolls 15, and 16. which control the motion of the patch web,
so that the said web remains stationary for a time with its advanced edge resting between the rolls 23, and 5. It will be noted that these rolls are not quite although almostV equal to that of theenvelop web, whereby the advancing edge of the patch web is brought into proper relation to the window of the envelop web, and, thereupon just as it is passing between rolls a, and 5, the
shearing knives again come into operation and sever the terminal portion, creating a new patch which continuing at the same speed, passes through rolls el, and 5, and is properly applied to the envelop web. The fact that the patch advances at the same speed before and after severance results in a cleaner severing operation than when different speeds are resorted to.
Having thus described my inventioml claim:
In an envelop machine, the combination of inca-ns for imparting continuous movement of its formation, is under control 'of the envelop web advancing mechanism, and is by it pressedA into adhesive contact with a window aperture of the envelop web; and said means for imparting intermittent movement to the patch web also comprising means whereby the dwell in the intermittent movement of the patch web is caused to commence from the completion of the severance of a patch and to continue until the ap-l proach of another window 'aperture after which the gummed patch web 1s motionless for an interval.
In testimony whereof, I have hereunto I signed my name at Philadelphia, Pennsylvania this tenth day of October 1916.
