Application filed. November 8, 1909. Serial No. 526,694.

To all whom it may concern; v

Be it known that I, FERDINAND L. SCHMIDT,

useful Improvement in Punching andfGumming Mechanism for Envelop-Blanks', of which the following is a specification, accompanied by drawings forming a part of the same, in which V Figure 1 represents a side elevation of an envelop machine shown in sectional view and embodying my improved punching and .ming mechanism. Fig. 2 is a front e evation of the punching and gumming mechanism shown on a larger scale. Fi 3 is a detached top view of the punching die. Fig. 4 is a side view of the punching die, and Fig. 5 is a plan view of an envelop blank after it has been punched and gummed. I

Similar reference characters referto similar parts in the different figures.

My present invention relates to a mechanism for punching an opening in the body of an envelop blank and gumming the marginof the opening to receive a transparent patch in the manufacture of what is known as outlook envelops, and my invention consists in the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

In the accompanying drawings 1, Fig. 5, represents an envelop blank in extended form, having end flaps 2, 2, a back flap 3 and a seal flap 4 which, folded on the broken lines 5, form an envelop having a rectangular body 6. The punching and gumming mechanism illustrated in the accompanying drawings is adapted to punch an opening 7 in the body of the envelopin proper position to disclose an address on the inclosure, and having the margin of the openin 7 gummed, as indicated by the shaded sur ace 8. The punching and gumming mechanism is shown in the accompanying drawings as forming a component part of an envelop machine designed to operate upon a ,pile or stack of envelop blanks for the purpose of gumming and folding the flaps of the envelop, but the ployed separated from the other parts of the envelop machine.

parts of the mechanism' a pileof. b anks 9,

from which the topmost blank is raised by flap gumming dieslO, 10 into position to be engaged by the hooks 11 of a reciprocating conveyer 12 and carried over a die plate 13 having an opening 14, corresponding to the opening 7 to be formed in the envelop blank.

' In the present application I have not. shown in detail the reciprocating conveyer 12 nor the registering means by which the blank is held in the various positions, these means having been fully described in Letters Patent of the United States, No. 401,462, issued to A. A. Rheutan, April 16, 1889. The die plate 13 is supported in a fixed position upon the table 15 of the envelop. machine, and is arranged to cooperate with areciprocating punch 16 having on its upper side lugs 17, which are connected by a link 18 with one end of a lever 19 pivoted at 20 upon the framework of the machine, and having its opposite end connected by alink 21 with a cam 22 on a cam shaft 23. i The cam 22 is con structed to depress thepunch 16 and allow it to be raised by means of a spring 24. The 4 punch 16 is thereby given a vertical reciprocating motion within a sleeve 25, which likewise is capable of a vertically reciprocating movement in fixed ways 26. The sleeve 25 is connected by links 27 with one'end of a lever 28, which is pivoted at 29 upon the framework of the machine and connected at its opposite end by a link 30 with an actuating cam, not shown, carried upon the cam v shaft 23, said cam being adapted to vertically depress the sleeve 25 in the ways 26 and allow' it to be raised by a spring 31. Inserted within a recess in the lower edge of the sleeve 25, or otherwise suitably attached thereto, is a strip of elastic material, such as rubber, forming a yielding face 32, to which gum is applied by a reciprocating gumming roller 33, supported in a frame 34 connected by a link 35 with a swinging lever 36 pivotally supported upon the framework of the machine at 37 and suitably connected with an actuating cam, not shown, to impart a reciprocating movement to the frame 34 along the horizontal ways 38, by which the gumming roller 33 is brought into contact at one end of its travel with a gumming roller 39 revolving in a gum box 40. During the reciprocating movement of the gumming roller 33, it passes into contact with the yielding face 32 when the latter is in its highest position, applying gum to the face 32 which is transferred to the envelop blank by the downward movement of the sleeve 25. Supported abovethe die plate 13 is a stripping.table 41, having an opening suflicient to allow the sleeve 25 to pass in its downward movement and bring the yielding gummed face 32 into contact with an envelop blank held in position over the die plate 13.

The operation of my improved punching and gumming mechanism when employed in connection with the operative parts of an envelop making machine is as follows Each envelop blank, as it is raised from the pile 9 by the flap gumming dies 10 in their vertically reciprocating movement, is

stripped therefrom by a stripping plate 42 and deposited upon thereciprocating con- "eyer 12 and engaged by the hooks 11. At the next forward movement of the conveyer .12 the blank is carried into position over the die plate 13 and given a period of rest, during which time the sleeve 25 descends carrying the gummed yielding face 32 into contact with the body of the envelop and applying gum thereto on the margin of thev opening 7 forming a med surface 8, as indicated by the shadmg 8 in Fig. 5. The punch 16 also descends and, passing into the opening 14 of the die plate 13, punches the 'hole 7, Fig. 5, in the blank. The punch 16 is then raised until its lower surface is brought above the gummed face 32, as indicated by the broken line 43, Fig. 2, thereby causing the envelop blank to be stripped from the punch. The punch 16 and sleeve 25 are then moved upward above the strip-' ping table 41, which releases the gummed blank from the sleeve 25, allowing it to rest upon the reciprocating conveyer 12 and be carried at its next forwardmovement to the folding mechanism, comprising a folding bed 44, plunger 45 and a creaslng plate 46, in the manner common in machines of this class.

The envelop machine, in connection with which my punching land gumming mechanism is illustrated, is provided with mecha-.

nism for feeding and applying a transparent strip from a coil 47 to cover the opening 7 of the envelop blank; but the patch applying mechanism employed for that purpose forms no part of my present invention, it being described in a copending application for Letters Patent, Serial No. 526,358, filed by me November 5, 1909.

I do not confine myself to the employment of a punching and gumming mechanism in connection with an envelop machine, as the same may be employed separately;

neither do I restrict myself to any particular type of envelop machine with which the punching1 and gumming mechanism may be employe I claim, c
