ABELrOF NEW ENVELOPE-FEEDING ATTACHMENT FOR TYPEWRITING MACHINES.

Improvements in Envelo v -Feeding Attach mcnts for Typewriting achines, of which the following is a specification.

()ne object of this invention is the. provision of an attachment which can be so an ranged in combination with a typewriting machine as to be bodily movable with the carriage thereof, and which manipulation of the typewriter platen. feed envelopes, post cards or other article or sheets of material to receive impressions one at a time, from a stack or bundle of same. thus rendering it unnecessary to manually insert each article in the typewriter. and re sulting in the saving of a great amount of time when it is necessary or desirable to address a large number of articles.

Another object of the invention is to provide a feeding device'which is readily attached to all standard makes of twpewriters,

I and is quickly put in or out of. operation. without interfering with the use of the typewriter in ordinary service.

A still further ob'ect is vice of this character in which the feeding roll thereof is driven from the platen of the typewriter so that the typist needs merely to rotate the platen in the usual manner to effeet the feed of one envelope or the like at a time to the platen, xhere being a hopper for the envelopes andguiding means where by the lowermost envelope of a stack of same is fed each time.

In the accompanying drawings illustrating the invention. in the several figures of which like parts are similarly designated. Figure 1 is a front elevation of a. typewriter with the feeding attachment connected thereto. the typewriter being shown in broken lines. Fig. 2 is a side elevation thereof. Fig. 3; isa section taken on line 3-3 of Fig ure 1. Figs. 4 and 5 are detail views of the envelope guide frame and the removable drive clamp respectively. Figs. 6 and 7 are views similar to Figs. 2 and l respectively, but showing the devices supported upon and carried by the typewriter carriage.

Referring more particularly to the drawings, the numeral 10 designates the typewriter earriage, provided with the platen 11 and the paper will. by the to provide a (le Application filed March 17, 1924. Serial No. -700,129.

snidel2. Sockets 13 formed on arms 14 an engaging a rod 13' carried by stands 13" may be used to support the hopper 15 and its associated mechanism free of the typewriting machine, or, as shown in .Figs. 6 and ,7 the attachment may be supported directly upon the carriage 10 by means'of arms 14=I Thehopper includes the side plates 16 held improper spaced relation by means of the front plate 17 and the rear guide plate 18.'while journaled in the plates transversely of the hopper is a shaft 19 carrying p-aper feeding rollers or wheels 20, preferably provided with rubber tires for bands. These rollers may be rigid with the shaft or they may be adjustably attached thereto. in order to rotate the shaft 19 simultaneously with the rotation of the platen. a' flexible shaft 20 is provided having one end fast to the shaft and its other end carrying a. connector or clamp 21 which may he removably attached to one of the operating finger wheels 22 of the platen, so that as the platen is operated by the other finger wheel 23. the

flexible shaft will transmit motion to the shaft 19 and consequently to the feed rollers 20. By employing the clamp 21, the flexible shaft may be attached or detached at will.

The front plate 17 is adjustably mounted to the side plates 16 by means of the screw and slot connections 24 and the two adjusting thumb screws 25, the" rims 25 of same being fitted in openings 26 in the plate. By this means the lower edge of the plate 17 may be moved to or from the feeding rollers'to vary the space for permitting the envelopes or other articles to pass between the lower edge of the plate and the rollers, and according to the thickness of the articles to be. fed.

Also carried by the plate 17 are two or more guide fingers 26 which parallel the paper guide of the carriage and insure the delivery of the envelope or other article in proper relation to the platen. Y

The rear guide plate 18 has attached thereto and projecting rearwardly therefrom two parallel plates or strips 27 whose upturned rear ends 28 are slotted to receive the presser rods 29, acted upon by the weight 30 to weight the envelopes or the like and insure proper pressure of the lowermost one upon the feed rollers, and laterally adjustable and properly attached to the strips 27 are L-shaped envelope guides 31. Each of these guides 31 is provided with a slot 32 for the reception of a screw 33, whereby the guides may be moved toward or away from each other and locked or clamped in proper position to accommodate envelopes or the like such a manner that it will be bodily carried by the carriage and move with it during the writing operation. By means of the drive clamp 21 on the flexible shaft 20 the feeding shaft 19 of the attachment is quickly attached to and detached from the left finger wheel of the platen, leaving the right one free for manipulating the platen and through it the feed rollers 0f the attachment. The hopper is made of a sutlicient size to accommodate a bundle or package of envelopes, cards. or the like of from 50 to and one envelope at a time is delivered automatically to the platen as the platen is rotated, either as the addressed envelope is removed or after its removal.

lVhat I claim is 1. In an envelope feeding attachment for typewriting machines, a unitary structure comprising a hopper adapted to receive a plurality of enlvelopes or the like in position to be fed to the platen of a typewriting machine, rotatable means for feeding said envelopes, flexible means for driving said feeding means, and a detachable connector for coupling said driving means to said platen and for uncoupling it therefrom at the will of the operator.

2. In an envelope feeding attachment for typcwriting machines, a unitary structure comprising a hopper adapted to receive a plurality of envelopes or the like in position to be fed to the platen of a typcwriting machine, rotatable means arranged in said hopper for feeding said envelopes, flexible means for driving said feeding means, and a detachable clamp arranged for engagement with the finger wheel of the platen for connecting said driving n'ieans to and disconnecting it from said platen at the will of the operator.

3. In an envelope. feeding attachment for typewriting machines. a hopper having a discharge opening and arranged to receive a plurality of envelopes or the like articles in stacked relation in position to be fed to the platen of a typewriting machine. a shaft journaled in said hopper and carrying a feed roller arranged in said discharge opening with which the lowermost article of the stack or plurality contacts, a front on said hopper arranged in cooperative relation to said roller to prohibit feeding of more than one article from said hopper at a time, and means including a clamp for detachable connection with said platen forimparting rotation to said shaft.

In testimony whereof I afiix my signature.

THEODOR CLAUS.
