T. bar 3 ot the frame lcarnes aria he cross supports a substantiallv large yoke 4. An

envelop plunger 5, of a particular construc-.

tion hereinafter ,more fully described, is carried on the lower extremity of a vertical hollow plunger shaft 6. Said hollow shaft is adapted to undergo a. vertical reciprocation and is confined in the bearings 7 of the frame and yoke. A cross arm 8 is fixed to the plunger shaft. Saidcross arm is provided with guides 9 adapted to reciprocate in contact upon tracks 10 formed on the member 4. A pair of links 8 are pivotally correlated with the cross arm serving to reciprocate, from a driving mechanism not shown. the plunger.

A table 11 is embodied within the frame and adapted to support various operating elements which are in no way correlated with this invention, hence they are omitted from this description and illustration. However, the folding box, that combination of elemeiits which creases and .folds the envelop, 'is here partially illustrated: and consists. of. the folding members 12 and 13 the under surface of the table.

ifrom the table 11.

which are pivoted to the table and adapted to undergo a certain movement about their pivotal point, said movement being controlled through members which are not associated with the invention and are therefore omitted. Also the trap 12 forms a part of the folding box and is pivoted to Said trap is of a particular construction as will hereinafter appear in detail. As each envelop is folded in the folding box the trap will drop or pivot down' causing the completedv envelop to be dropped in the drying rack, not

shown.

The elevator 14 which generally carries the stack of envelop blanks is mounted in a usual form of track support which depends This elevator consists of. the member 14 having integrally formed therewith vertical guides 16 which are confined in the track 15. This elevator, as understood by those conversantwith the art, is provided with means for raising and lowering it in the track. In this instance a hand wheel 17 is fixed to a shaft 18 which carries pinion 19 adapted to engage a rack 20, which is confined in the track 15. A ratchet wheel 21 and pawl 22 are provided to hold the elevator in its upper positions of the weight of its supply of envelops. -In Fig. 2 the elevator is in its lower position and carries a supply of envelop blanks. I A picker plate 23, also known in the art .as a stripper plate, is here illustrated. In

Fig. 2 said member is shown in section, ill us 'trating the several apertures through which the picker plunger or gummer descends until it is in contact with the top envelop blank, carrying same up to a conveyer mechanism 24. whereby the blank is delivered to the whether or not the machine is equipped with this attachment comprising the invention.

During the operation of the machine the elevator is. adjusted high enough for the top of the stack of blanks to be adjacent to the under surface of the stripper plate. As

the pickers descend through the apertures of the stripper plate and gum the top blank,

said blank will adhere or stick to the'gummed plcker which will immediately start on its return trip when thetop blank will be picked from the picker by the plate, which operation merely allows the blank-conveyer to pass under the blank adhering to the gunnner and carry it to the plunger.

The mechanism just described and which relates to the various movements of those elements which control the envelop blank after appear in detail, correlated with the invention, hence the description and illustration of those few parts Generally speaking, the foregoing description may be taken to apply to a machine to which the attachment can be quickly and v are fixed to the extremities of the actuating rod. Contact lugs 30 are carried by each extremity of the cross arm 8 and projected beyond the tracks 10 and lie within the vertical path of the trip members.

It should -be understood 'that'this machine is adapted to handle any. size and shape patch, the one here illustrated merely being an example of one shape of patch which can be easily handled by the machine. a

The position of the elevator .14 in Fig. l

- is shown 'in its lowermost position to which nisin was released by the operator which al--- ithad been lowered to be refilled with en'- velop blanks. \Vh'enthe supply of blanks becomes low or runs out the ratchet mechalowed the elevator to'descend to the position shown. Associated with the-invention is means for cutting off the suction from the system and particularly frdm the patch carrier.

A cut-off valve 7 O is provided inthe suction. line. A substantially lon depending control rod 71 is correlated with-t ie valve and lies along and adjacent tothepath of travel of the elevator 14. Trip members 72 are fixed to the member 71 and-project over and within thevertical path of travel of the elevator 14. The lower extremit of the control 'rod 71 is slidably retained y a bracket 73 which is in fact rigidly mounted on portions of theflframenot shown.

In its lowermost position as illustrated in Fig.1 the elevator has engaged the lower trip finger causing-the member 71 to undergo a downward displacement thereby closing the valve 70 and shutting ofi the suction from the valve 25 which cuts off the suction from all elements which are controlled'by the said valve. -This is 'seen' to be an auto-- matic means for stopping the suctionflo'w through the pivoted carrier; which is necessary to prevent the picking .ofi of-the patches while the machine is running and while theoperator is. placing-onthe elevator a new supply of blanks. Also'this'de'scribed element of the invention contributes to economical use of the air exhausting device as it allows the suction to ply. through the pivoted carrier and plunger only when said elements are in the actual operation of'carrying the blanks and patches. When the eleva- 3 tor is given its'upward movement and the blanks are brought adjacent to the stripper plate, as shown in Fig. 5, ready for delivery, the upper trip finger 7 2 is contacted which causes the valveto be opened.

A description will now be given of the operation of the; machine with a view ofi further explaining the principles and func. tions of the invention. Particular atten-' tion to Figs. & and 5 in connection with all the views will give the location anddisposition of 'parts during the periods of each cycle ofoperation.

The position of the va' rious moving parts in Fig. lis taken as'the plunger is going up, at which time the said plunger is relieved from the patch and blank which it previously -.car-ri'ed. down. The

patch; carrier, through the-agency of the link-52, has just pickedoil, by suction, a"

patch from the magazine and is'carrying it about 1ts arc of revolution, toward the plan ger which by this time has reached its uppermost position as shown in- Fig: 5; at Y which time the patch carrier SllCiLlOIlhOZZlBS' have passed, up into the slots 58 ofthe plunger. At: this point the contact points 30 have impinged the upper trip members '29 causing the valve 25 to stop" the-suction through the tube 49-and patch-carrier which releases the blank 0 from thepatch carrier;

and the valve 3750 set as tostop the ad'- 1 plunger. Simultaneously with this release the tube 36 position-ofplunger and suction nozzles is shown in Fig. The contact lug or point a ing plungershaft, impinged the upper 'trip diverted into the hollow; plunger and closed 30, which is correlated with the reciprocate 'member '29 which controls the-valve 37 just beforethe valve 25 was actuated. This action took place'just before the suction was the valve 37 thereb stopping the admission ofyair to the p linger, 'which was ad mitted to, destroy the partial vacuum while j the plunger .wasdown', and making it possiblefor a partial vacuum to be created with v in the plunger at the instant .said plunger was at the top.
