T0 /LZ/ wi/mn, it nay concern: y

Be it knowui that I, FRANK D. BULLARD, a

citizen of the Uni-ted States, residing at Los y Angeles, vin .the county of Los Angeles and State of California, have invented a new and useful Feeding Attachment for Type-Writers, of which the following is a specification.

VMy invention relates to a. feeding device for attachment to typewriters by means of ing attachment described herein and illustrated in the accoii'ipanying drawings in W,hich:-

Figure 1 is a perspective view oi the liront of my feeding attachment showing it in place upon the 'carriage of a Smith-Premier, the lower portion of ythe machine being omitted for clearness of illustration. Fig. is a plan of my feeding device detachedi'roni the machine. Fig, 3 a section ol the same on the line 3 of Fig. 2 looking in the direction of the arrow. Fig. il is a section on the line -t '-i ol Fig. 2- looking in the direction oi the arrow. Iiig. 5 is a detail of thc locking mechanism by means ol'V which the opcratin' @fear are locked together when in use. Fig 6 is a detail showing how the attaching a. ins oi the feeding device are secured to the carriage.

In .the drawings I have illustrated my .teoding attachment as applied to a Smith Prcniier typewritiiig machine and will describe it herein with reference to that machine.

My feeding attachment is adapted for use with any ol" the standard typcwriting machines but requires slight modifications as to its attaching arms from that shown and dcscribed herein to adapt it for attachment to thc diilercnt nialies ol' machines.

In the drawings A is the axle of the platen B ol an ordinary Smith-Premier typewriter'. Near the outer end of this axle and rigidly secured thereto and preferably on the left hand.

`side thcrcol' is secured a gear C which is adapted to mesh with a gear l) which gear is piovided with a hub l and is rotatively mounted upon a bearing E secured to the base plate I F of the magazine.

The axle G upon which the gear I) is rotatively mounted supports an L-shaped arm II whose upper end supports axle I and the other end passes rearwardly just below the base plato I" and is adapted to be engaged by the regulating screw J which passes through the base plate in threaded engageinent therewith so as to bring the axle I closer to the face K of lthe magazine K which is open at the top.

'lo the axle I. is rigidly secured the feeding roll Ii which is preferably made oi rubber prol vided on the surface thercol" with a plurality of rows of flexible feeding arms l] which are adapted to engage with tno envclops afin the magazine upon the rotation of the roller and draw one at a time out of such magazine and feed it in behind the platen whcrc it passes through the machine in the usual manner. 'lhe other end ot axie I passes through the upper end of arm M, which is secured to a bearing N fastened to the hase plate. 'lhe arm hl is L--shapcd lilic the arm lil and passes rearwrdly under the hase plate and is engaged by a regulating screw O which passes therethrough in .threaded engage nent therewith to bring the end of the anic closer to the .iront of the magazine. The inner ends of the arms II and i\l are fastened together by strip I so as to steady the same.. A spring Q secured to the 'base bears agimst this hinding strip l? near the arm so as to koop said arm spring pressed against thc regulating screw O.

'lhe axle I has a pinion It rigidly sicurcd thereto, which pinion meshes with the gear l) and rotates the l'ccding roll when the gear D 'is rotated. Gear C is provided with a hub C upon which is mounted a locking lover S having a hooked end S which is adapted to engage the hub D and lock the gears I) and C from separating when he front end thereoi is thrown downwardly in its operative position as shown in Fig. l. Axle I is longitudinally movable through arms Il and M and provided with a collar I between which and arm II is a coiled spirng 'l` which holds the axle normally in a position in which pinion l( meshes with gear l). Iivotally mounted in bearings M which bearings are secured to oi' are integral with arm )l is 'am V having a handle Y which cani is adapted to be brought into engagement with the cud ol axlc l and lorcc the same longitui'ilnally in its bearings l'ar enough to cause the disengagement of IL-O IIO

pinion R from -gearD, thereby stopping 'the movement of the feeding roll whenever it is ops therein in proper alinement. -per arms Ypass over the -top of the front of desired tohave theivsa'ine stopped.

The face ofthe magazine 1s preferably a thin 'sheet of metal which does not extend entirely to the base plate but leaves a feeding slot W through which the feeding arms engage the envelops to draw them out of the magazine. To the front ofthe magazine is` secured a guide rod-X on which are slidably mounted guidingarms having a hub Y, one

branch Y" of which extends downwardly to guide the envelops behind. the platen and the'other arms Y and YW extend rearwardly` into theA magazine to keep the envel- The upthe magazine and the arms Y" pass below the front of the magazine and through slots b vin the traveling follower b' which is within the magazine,` which follower is pressed by spring c against vthe envelo'psto keepvthem in an upright'position against` the front of the magazine. The follower is provided with a rod d which passes through the-back K of the magazine and through a plate e secured thereto. lIt is pro vided with notches d which are adapted to en age with the plate e when the follower is puffed toward the back and hold. the follower against the pressure of the spring c so that anew lot of envelops may be put into the magazine after the same magazine in threaded contact therewith sov becomesempty. Sprin c is' secured to a plate j which is adapte` to be engaged b5. screws g which pass through the back of the as'to regulate the tension of spring c. There the three of these screws spaced apart, two at the bottom and one'at the top so that if desired a vgreater pressure may be placed upon the bottom of the envelops than at the top. At each end of the base plate are'attachinv arms by means of which the. device is secured to the frame of the carriage. vThe attaching' arm h has a gro'ove h therein which groove fits upon the end bar i of the carriage of the machine. v Pin passes down back of the back bar lc of the carriage and thereby prevents the feeding device from moving too far making the surface o f the feeding roll sufficiently resilient and providing it with a proper engaging surface these arms may be dis ensed with.

vthe operation of my feeding device Patent isz- 1. In-a typewriter the combination of a 105 gear on the after it is placed on the carriage and the gear thereon lockedso as to engage with the gear on the platen, the follower in the magazine is drawn to the back thereof and held there while the envelope or other articles are placed 7 0 therein, Whenthe follower is loosened and spring presses them against the front of the magazine so that the lower edge of the article in front is in contact with the feeding roll.

Now by causing the rotation of the platen in the usual manner the envelop or other article at the front of the magazine is fed therefrom by the'fecding roll behind the platen, when it passes through the machine in the usual manner. `As' soon as an article has been 8o caughtl by the platen the further revolution of the feeding roll can be stopped by throwing the cam V so that it will engage with the axle of the feeding roll and move the same longitudinally to cause the disengagement ofl the pinion on the end thereofI with the gear with which it meshes. This is sometimes desirable as it removes the friction on the operation of the platen which is caused by the operation of the feeding device. is desired to have another article fed into the machine the cam is thrown out of engagement with 'the axle of the feeding roll, when the spring thereon returns the pinion into .enl When the feeding 19 5 gagement with the gear. device is not required the magazine can easily be detached from the carriage and ut aside and all the parts that remain attac led to the carriage are the locking lever and the gear on the platen which do not in any Way roo interfere with the use of the machine. y Having described my invention what I claim as new and desire to secure by Letters carriage having a platen; a magazine removably secured thereto; said magazine having a feeding-slot therein.; a feeding roll revolubly mounted adjacent to said feeding-slot in bearings secured to said magazine; a pinion no secured upon the feeding roll, a gear secured to the platen; a gear revolubly mounted in bearings secured to the magazine and meshing with the pinion on the feeding roll and the gear on they platen; a. lever having a curved end pivotally mounted on the platen; said curved end being adapted to lock the platen to the gear on the magazine,

such as described herein a revoluble feeding roll longitudinally movable in its bearings; a' cam lever mounted in bearings secured to the bearings of the feeding roll, said cam lever being adapted to move said feeding roll longii 2 5 tudinally in its bearings in one direct-ion; a

spring bearing against said feeding roll and l adapted to return it to its normal position l upon the release of said cam.

3. In a typewriter the combination of a rg0 1 As soon as itpgo 2.
