lposition `for writing.r Means are provided for quickly and easily throwing the attachment in or out of operation. The holder is adjustable to receive envelops of various The invention is illustrated in the accompanyingdrawings, in which Figure 1 is a perspective view thereof removed from the typewriting machine. Fig. 2 is a vertical cross section showing the attachment applied to the carriage of the machine. Fig. `3 is a detail of one of the brackets which support the device on the carriage. Fig. 4 is a 'detail in top plan of the rear part of the device.

Referringispeciiically to the drawings, A indicates the carriage of the typewriting machine, B the platen, and C the paper guide. The device forming the subject of this invention is mounted upon the carriage and is movable there-with.

The niain frame of the envelop holder is indicated at 4, comprising parallel bars having upright portions at the rear end connected by across bar, forming an angular traine on which the other parts are mounted. 'lhis frame is supported by hinged brackets ,consisting ot' upper portions 2() screwed into the under side of the bars, 4, and lower angular portions 21 which are hinged to the upper portions, as at 22. The lower ends of the parts 21 are arranged to fit in holes in the side bars of the carriage, to support the attachment upon the saine. The hinges 22 allow the frame toi rock to a limited extent, the hinges being suuiciently tight so that the attachment will stay as set. The rocking referred to throws the attachment in or out of operation as will be hereinafter described.

At 5 are indicated angular side bars the free ends of which extend inwardlv through l takes the Specification of Letters Batent.

where they are fixed by set screws 23, S0 that said side bars can be adjusted'in or out and set t'o hold envelops of any length..

Top bars are indicated at 10,'having at the rear ends downwardly-extending portions which are yieldingly clasped under spring strips 25 secured tothe cross piece of the frame 4, and said bars can be raised or 10W- ered to accommodate envelops of various heights. At their front ends the bars are provided with stops 10a which act to engage and hold the first envelop at the upper edge thereof. l l

Mounted in bearings in the front ends of the bars 4 is a shaft 12 which has at its ends friction rollers 8 which, when the device is in operation, bear upon and are rotated by contact with the platen of the machine. The shaft also carries releasing devices, each of which consists of a disk 18 havingradial iingers 19, and the releasing devices are preferably located on the shaft adjacent to the ends of the bars 4. 'Ihe ends of said bars have on their u per side projections 26 against which the rst envelop stops.

To advance the envelops toward the re# leasing devices atthe front of the arms,'a plate 7 is provided, resting upon the horizontal portions of the bars fi and supported at the ends bythe side rods 5 which fitin slots 7 a in the ends of the plate. On the rods, between the plate and the inwardly-extending rear ends of the rods, are coiled springs 7.1, which press vagainst the plate, and tend to force 4the saine forwardly.

The envelops are placed in the frame formed by the hars 4, 5 and 10, with the first envelop,'thatis, the one at the front, bearing against-the projection 26 andthe stops 10, and with the plate 7 pressing against the bunch. The length of the fingers 19 is such that they will just reach the lower edge of the Vfirst envelop, that is, ,the one against the projections 26. The wheels 8 being in frictional contact with the platen, turn of the latter causes the wheels and shaft 12 to turn, and the fingers 19 engage the first envelop and lift lthe same, carrying its loweredge over the projections 26 and beyond the ends of the bars 4, thereby releasing said envelop and allovng it to drop betweenthe platen and the paper guide, whence it maybe fed to the machine in the usual way. The springs 7b advance the pack so that another envelop place of the one released "i-nreadiholes in the uprighti portions of the bars 4, l ness for the next operation.
