PAPER-FEED ATTACHMENT FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Jan, 18, 1910.

Application filed January 19, 1909. Serial N 0. 478,173;

To all whom it may concern: Be it known that LWrnnnrRrnenLrDrxon, a citizen of the United States, residing at Roanoke, in the county of Roanoke and State of Virginia, have invented a new and useful Paper-Feed Attachment for Typeriters, of which the following is a specification.

This invention has reference to improvements in paper feed attachments for typewriters and is designed to provide a reservoir for sheets of paper to be fed successively and automatically to the platen into position to be operated upon by the type without the necessity of the operator placing the sheets as needed; v.

The invention is designed particularly for the feeding of sheets of paper, where many sheets are to be used, in succession and rapidly, the speed of the use of the machine being thus greatly augmented by avoiding the necessity of the operator stopping the typewrit-ing in order to change the sheets.

The present invention isdesigned to be attached to any of the commercial forms of typewriters, being connected directly to the carriage and provision is made for the feeding of the sheets one at a time'and in succession to the proper side of the platen, the feeding bein performed automatically byand in accor ance with the movements of the platen in the act of typewriting. The structure is such that when a sheet is removed from the typewriting machine the next sheet has already been automatically moved into position with relation to the platen to continue the typewriting.

The invention will be best understood from a consideration of the following detail description taken in connection with the accompanying drawings forming a part of this specification in which drawings,

Figure 1 is a perspective view of the at tachment applied to the carriage of a cominercial form of typewriting machine, Fig.

'- 2 is a:vertic'al section through the structure shown in Fi I. Fig. 3 is a plan View of a portion .of t e reservoir with the cover removed and ,with' parts shown in section. Fig. 4 is a detail section showin the actw ating gearing for the feeding r0 er forthe paper Fig. 5 is a detail v ew-showing a form of support for the attachment adapting it to a different type of typewriter machine than shown in Fig. l. '6 is a detail view of a support for the end of the deed roller remote from the actuating end.

Referring to the drawings there is shown a typewriter carriage 1 which may be taken as typical of any typewriter carriage and the platen of the carriage is indicated at 2.

Fastto' a portion of the rear of the carriage near each. end thereof is a block 3 in the upper end of which is formed a socket for socket by means of a thumb screw 5 so'that therod may be readily inserted or removed" at will without the use of. tools. A set screw 6- serves to holdtheblock 3 in place since it is notnecessary to remove the block in order to remove the attachment and the block may therefore be considered "ass permanenthttachment to the typewriter carriage"if so desired. -The upper end of the an angle away rod 4 is flattened and bent at from the platen and is provided with two holes for the passage of bolts 7.

The rods'l, there being two such rods, one near each end of the typewriter carriage, serve, as a support for a reservoir 8. The heads of the bolts 7 where they eittend through the. v slots 9 through the corresponding wall of the reservoir .so that a certain amount of adjustment is provided for setting the reservoir to proper relation to the platen'fland after the adjustment has been made then the nuts of thebolts may be tightened, thereby holding the reservoir in proper posit-ion.

The reservoir is shown as U-shaped in cross-section and is as long or slightly longer than the used. The 0 en end of the reservoir is toward the platen as indicated in Fig. 2

and fast to the lower side of the reservoir the-reception of ii rod 4: held in the walls of the reservoir 8 play in width of the paper to be 8 is a low partitionlt) which may extende11 tirely' across the l, on is much shorter than the lower face and .to

eservoir if so desired and} the end of the upper face there is hinged a continuation 12 in the nature of a cover and this continuation or cover is provided with a projecting lip 13 inclined downward at an angle to thenia n portion of the cover 12 for a purpose which will presently appear, while the free edge 14 of the lip 13 is bent at an angle to the lip, as indicated in Fig. 2.

' there engaged by springs 18 each connected.

to the corresponding end of the rod 15 at one end and at the other end to a suitable portibn of the reservoir 8. The tendency ofthe springs 18 is to move the cover 12 toward the other side of the reservoir for a purpose which will presently appear.

At one end of the reservoir there is a casing 19 housing two gear wheels 20 and 21 in mesh one with the other. wheel 21 is formed with or has secured to it a stub shaft 22 extending through the corresponding end wall of the reservoir 8 and terminating in a squared section 23 within.

said reservoir. This squared section 'is adapted to enter a square socket-in a roller 24 within the reservoir beneath the cover 12 adjacent to the point of junction with the cover of the lip 13. The other end of this-roller is supported in a bracket 25 shownseparately in Fig. 6. This bracket is designed to be riveted or otherwise secured to the other end of the reservoir on the inner face thereof and is provided with a socket 26 adapted to receive an axial stud on the corresponding end of the roller.

hen the cover 12 is lifted then the .roller 24 may be readily removed by disconnecting it from the bracket 25 and then pulling it away from the squared portion 23 of the stub shaft 22.

shaft27 and on this shaft exterior to the casing 19 there is mounted a sprocket wheel 28 having a clutch member 29 on the side thereof remote from 'the casing 19. This sprocket wheel 28 is free to rotate .on the shaft 27 but may be coupled thereto by another clutch member 30 rotatable with the shaft'but also capable of sliding'thereon. The clutch member 30 is ur ed constantly toward the clutch member 29 by a spring 31 surrounding the shaft27 and confined between said clutch member 30 and a head32 formed on the outer end of the shaft. I

" The clutch member 30 carries a collar 33 in which the clutch member 30 is rotatable and this collar is engaged by a fork 34 straddling the collar and connected thereto by pins 35 at diametrically opposite points. The fork 34 is fast to one end of a lever 36 pivotedto a bracket 37 projecting from the corresponding end wall of the reservoir 8. This bracket also carries a spring member 38 normally tending toward the bracket 37 The gear and mounted on the side thereof remote from the lever 36. The spring 38 is provided with a projecting finger or stud 39 adapted to be brought into the path of the lever 36 on either side thereof. 1

When the lever 36 is moved in a direction ,to separate the clutch members, which movement is against the action of the spring 31 the finger 39 will maintain the lever in such position. I When it is desired to bring the clutch members together it is only necessary to move the spring 38 in a direction to carry the finger 39 out of. the path of the lever 36 when the spring a 31 will cause the two clutch members to be brought into engagement thus coupling the sprocket wheel 28 to the shaft 27.

Mounted on the;arbor of the platen 2 is a sprocket wheel 40 and the sprocket wheels 28 and 40 are connected together by a sprocket chain 41, the continuity of which may be broken by the separable coupling 42 .providedfor the ready separation of the chain when it is desired to remove the attachment 3 from the typewriter and for 'the ready coupling of the end of the chain when it is deslred to installthe. attachment on the type-.

of the chain avoids the necessity of dismantling the typewriter carriage to the extent of disconnecting the platen 2 therefrom; Whenever the platen 2 is rotated then, the gear wheel 27 is likewise rotated if the clutch members 29 and 30 be in engagement, and this rotation is imparted to the roller 24 through the gears 20 and 21.

Within the reservoir .8 there is located a follower 43 under the control of two spaced thumb screws 44 each having a threaded bearing in the partition 10 before referred to, so that the follower 43 may be moved to The gear wheel 21 is mounted on a stub and from the partition at the will of'the operatorI The inner face of that portion bf the reservoir over which the follower 43 travels is provided with index markings 45 so that the follower may be adjusted for paper sheets of difiereut lengths. Upon each thumb screw 44 there is a clamp nut 46 so that when the follower 43 is adjusted the thumb screws may be locked in placethus insuring the maintenance of the adjustment of the follower 43.

.writer. The ready coupling or uncoupling Extending from the lower portion of the reservoir down to a point close to the platen 2 is an apron 47 secured to the post 4'by one of the bolts 7 in each post. The outer surface of the roller 24, as well as the inner surface of the cover 12 is rough ened preferably though not necessarily by the application of emery thereto. Thisemery surface which maybe produced by the application of emery owder and a suitable cement is shown'on t e roller at 48 in Fig.

4 and on the cover at 49- in Fig. 4. 3 Within the reservoir there is shown a stack.

sea /2e of sheets 50 of the paper to be used'with the typewriter. In order to place these sheets of paper in the reservoir the cover 12 is raised and the roller 24 is removed after which the sheets of paper bent into U form are introduced into the reservoir with the the stack of sheets is sufliciently elevated the roller 24 is replaced"'and then the cover is brought down so that the roller will engage the innermost sheet of thestacli, the latterbeing held to the roller by the Tet-motive force of the springs 18. The follower-43 is adjusted to conform to the length of the sheet so that the overlapping ends will be brought into engagement with the lip 13 as indicated generally in Fig. 2. It now the platen 2 be turned in the direction necessary to feed a sheet of paper around the same the motion is transmitted through the chain 41 to the gear-wheel 21,. the clutch members being then in engagement, and this motion is imparted "to the roller 24 in a direction however the reverse of the direction of rotation of the platen '2 so that the roller 24: will.

tend td move the adjacent sheet of the paper in a direction out of the reservoir and under the li 13 when it is directed toward the apron 4 by the continuation 14 of the lip 13 and-is ultimately guided into position to be fed to the platen and engaged by the same in the usual manner.

Let it be assumed tha-ta sheet of paper has 7 alreadynbeen fedto the platen and that anothersheet is being fed thereto as indicated in Fig. 2. It will be noticed that the second. sheet overlaps the'firstsheet for a distanceso that by the-time the-first sheethas' bee n moved out ot the line of the type the second sheet has been moved into the line of the type witha suitable upper margin. This is due to the overlapping of the shee'ts'at the I feed endof the reservoir since whe a sheet escapesfrom thei'oller 24 the next ceding sheet for a like distance;

in the reservoir. it As the sheets are fed out fromthe' reservoir the next succeeding sheets new supply maybe quickl are lrept in Contact with the roller 24 by the action of the springs 18 moving the. cover 12' toward the said roller,

When the sheets have become manner already describe Should it be eet is engaged at a point somewhat distant from its end so that it. tends to overla; the pre'- his-is dueto the manner of supporting the sheets withexhausteda inserted in the desired to: use sheets of a greater or shorter length than-those for which the'reservoir is first set, .the' follower 43 may be readily adjusted to accommodate such sheets so that the overlapping ends have always the same relation to the roller 24, and the follower 43 also serves, for the alining of the corresponding ends of the sheets without attention on the partof the operator.

The attachment is adapted for difi'erent commercial forms of typewriters andin Fig. 5 is shown a'block 3 whereby the attachment may be connected to the typewriter carriage of a different style of typewriter than-that shown in Fig. 1. This may be taken as indicativeof the manner of conmeeting the atta'chmentto different styles of typewriters and it will therefore be unnecessary to show other forms of connecting blocks since the only change in the structure needed to adapt the attachment to various makes of typewriters is in the form of the attaching block 3 0 3.,
