- To all whom it my concern:

- typewriter behind the Be it known that I, CHARLES L. DAVIS, a citizen of the United States, residin at Detroit, county of. lVayne, State of MEM- gen, have invented a certain new and useful Improvement in Envelop-Feeders, and. declare the following to be afull, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to envelop feeders.

It has for its object an improved attachment adapted to be used in connection with typewriters or other addressing machines for the purpose of feeding to the platen or printing roll envelops to be used in the machine, and for the purpose of removing the envelop from the platen after it has been printed and contemporaneously with the insertion of a new envelop upon which the succeeding imprint is to be made.

The drawings are diagrammatic.

In the drawings :Figure' 1, is a-side elevation indicating the typewriting machine andshowing a side elevation of the attachment. Fig. 2, is a section on a surface parallel with the plane of the sideelevation of Fig. 1. Fig. 3, is a front elevation of the storage hop-per. Fig. 4, is a cross section through the platen and the primary receiver of the printed envelops. Fig. 5, is a detail showing in part the end of the storage hopper used where large numbers of envelops are to be printed. Fig. 6, is a front elevation on a smaller Scale of the bearing late 6 shown'on F ig. 1. Fig. 7, is a detail e evation, partly in section, of the spring supported primary actuating bellows and its adjacent parts.

The attachment consists of a hopper in which a number of envelops are laced and arranged with that edge of each f om which the usual sealingfiapextends, placed to the bottom 'of the hopper. envelop under the flap and between the'flap and the body part of the envelop and pushes it out from the hopper onto the paper guide laten of the typewriter, and inem underneath the platen of the that the rolling platen continues to move the envelop forward; and it is brought around 'to proper posltlon for the. op ,-a.'fter which the.

A finger engages the serts it so platen continues its feeding movement, and carries it up betweenv guides and it comes to rest with the bottom edge (the edge opposite the flap edge) resting on the top run of the platen and wit-h the 'envelo itself resting in an inclined position against the rest or against an envelop that has .been previously treated where it remains until the operator of the typewriter desires toremove the addressed envelop from its position, or, if the receiving hopper 16 is employed, the finger which feeds the on-coming envelops grasps the finished envelop the guide plate 6 and drops it into the storage hopper 16, where it remains until the accumulation is removed by some. means.

The primary receiving or storage hopper 1 is mounted at the rear of the typewriter on suitable supports 2 properly secured. and braced to the typewriter frame and arranged with its bottom 3 inclined to the plane of the table upon which the typewriter rests. The hopper 1 is provided with 'a follower 4 that rests upon the bottom 3 of the hopper, and maintains the envelo s contained in the hopper, and in front of t e follower in a sufficiently compact relation so that the foremost of the envelops enga es quite closely against the end 5 at .the front of the hopper. The lower edge of the end 5 is so far spaced from the lower front end of the bottom 8 of the hopper that an envelop may he slipped through between the end and the hopper bottom; the face of the end 5 is cut away to provide a. broad and the plate which is sufficient in extent, along the retaining end 5 from end to end of the notch 7 to allow the flap of the envelop to spring out from the=body-thereof, as it will do naturally, as envelops are. ordinarily made, sothat the finger 9 will readily enthat edge of the notch that lies downward is provided with side notches 11 triangular in'shape that give still greater freedom to the flap 6, while the inward projecting ends 12 below the notch 1 serveto' prevent any im r0 er bendingor arching of the envelop.

Preferably,

in the drawing the connection is made to a stud that rises from the bottom 3 of the hopper and the lever 14: is so angled or arched that in its rocking or oscillatingmovement which will be described, it is at all times clear from the envelops in the hopper. The downward throw of the lever 14 is regulated by an adjusting screw 19 properly maintained with relation to the.

' this description, and the one which I prefer to use employs an air conduit and pneumatic bellows, of which'the primary actuating bellows 17 is itself actuated by the oper ator by means of a push key 18 that resembles the ordinary levers of the typewriter, and the lever is shown to be actuated as a suction bellows expanded by the operator igainst the tension of the spring 20 which serves to collapse it when the finger of the operator is removed from the key 18. The air conduit 21 leads from the suction bellows 17 to the bellows 22 that is secured to the frame-work of the hopper 1 at some posit-ion convenient to the lever 14 and a link 23 pivotally connected to the bellows 22, or an' extension from the bellows 22 is also pivotally connected to the lever 14: and actuates the lever 14 upon the actuation of the bellows 17. A counter-weight 24 on the projecting rear end of the lever 14 is adjustable to bring the acting parts into a condition of substantial balance.

The envelop, pushed by'the finger 9 into feeding relation between the paper guides 25 and the platen 26, is seized by the platen and fed forward when the platen is turned by the operator in the usual way, and brings the envelop to a position for the action of the type thereon, after which the continued movement of the platen carries the envelop behind the guide 27 and against the rest 28 that is located in an inclined position above the platen and somewhat to the rear. of the upper run thereof; the envelop takes a position against this rest with an inclination that is practically parallel to that which it occupied in the hopper 1. If the final storage opper 16 is used, a pair of split fingers 29 are secured to the front of the finger 9 in relation to engage between their spreading members and the'top edge of the envelop 10 when the front end of the lever 14 is depressed in the act of inserting a following envelop under the platen. The split and spreading fingers 29 are of light, flexible, resilient material and are sufficiently rigid to maintain their hold on the envelo and draw it up from under the pressure p ate 6 until the bottom of the envelop clears the top of the pressure plate 6, and also until the now top edge of the envelop engages the projecting bar 31, which stops the envelop and allows the fingers 29 to draw away from the envelop and release it when it drops on the now top or forward'surfaoe of the plate 6, and slides into the hopper 16. The plate 6 is in pivotal relation with the rear of the hopper 16, and serves not only to press back the envelop against the rest 28, but after the envelop has been transferred to a position above the plate 6 and has dropped and slid partly downit serves to continue the travel of the envelop into the hopper 16 as it is itself lifted by the next succeeding envelop in process of transfer. The fingers 29 travel clear of the plate 6 which is deeply notched between its ends and at the notched part forms no obstacle to the fingers 29, although its end parts 6. extend back and project over the envelop resting against the rest 28.

The storage hopper 16 is not necessarily used with the remainder of the attachment. It is preferably employed where quantities of envelops are to be addressed because it is capable of containing a larger number of envelops than can be stored at one time on the machine without it. The machine without this storage hopper is shown in Fig. 1, which is suflicient for the storage of a few envelops, 30 or 40, and this may be removed by hand and the use of the storage hopper 16 entirely omitted if desired.

What I claim is 1. A feeding device for typewriters, having in combination a hopper, an oscillatory expelling member engaging across the delivery end thereof, a lever actuating the same, a counterweight mounted on the end-of said lever, pneumatically controlled actuating means connecting said arm to the key board of the typewriter, and a key controlling said pneumatic actuating means.

2.

3. A feeding device for typewriters, having in combination a hopper, an expellin member, a lever adapted toactuate said expelling member, a bellows actuating said.

lever, a second bellows adjacent the key board of the typewriter, a key adapted to.
