Specification of Letters Patent.

i Application filed February 26, 1906. Serial No. 302,902.

To all whom it may concern.-

Be it known that I, BENJAMIN F. HUToHEs, Jr., a citizen of the United States, residing at New York city, Manhattan, county and .5 State of New York, have invented new and useful Improvements in Automatic Paper- Feeder's for Type-Writers, of which the following is a specification.

' This invention relates to means for removing the old sheet and feeding a new sheet to a type-writer when the writing on the old sheet has been finished. The sheet-feeding mechanism is actuated by a key upon the depression of which the old sheet is removed anda new sheet is drawn out of a magazine and properly positioned upon the platen. This ey is preferablynot connected to the typewriter frame itself, but to a separate typewriter operator'such, for. instance, as described in an application for a patent filed by me May 15, 1905, under Serial.No.- 260,413. This operator when coupled to a type writer produces simultaneously with the writing a perforated record thereof, so that when the record is subsequently fed through the operator such writing may be multiplied any desired number of times. The operatoraccording to the present invention is provided with a be depressed by t e manipulator at thc'end.

of the writing when the operator is worked manually. This depression of the paperfeed key will cause the old sheet to be ejected from the ty e-Writer, a new sheet to be introalso a feed-perforation to be punched ,into the record. When subsequently the operator is actuated by such record, this perforation will serve to automatically actuate the paper-feeding mechanism at the end of each writing. Conse quently the machine will now produce auto matically copies of the writing for as long a time as it is allowed. to run and without requiring the services of an attendant for renewing the sheets. y

The letter a indicates the casing of a typet which is separate from and latter is provided with the usual reciprocating carriage b, in which the printing roller or platen b is rotatably mounted. The means for automatically turning the platen for oneor more line-spaces are not shown and do not form part of this invention. Means, hereinafter described, are, however, shown for imparting a turn to platen b when a written sheet is to be removed and replaced by a blank sheet; For this .purpose I mount in carriage b a feed-roller c, which is arran ed 7 parallel and in proximity to platen b R0 ler -c is rotated from the latter by frictional contact, which contact may be increased by providing roller 0 with a covering 0 of rubber or other resilient material. Above roller 0 there is secured to carriage 6 by brackets a magazine D, containing a stack of blank sheets A. MagazineD is composed of an inc'lincd bottom d, side walls rl d and front and rear walls (1 d. The magazine isso arranged that the edge formed between bottom- 01 and front wall d is located vertically above the axis ofroller 0. Along such edge I provide bottom (I with a longitudinalslot (i while a guard d, curved concentrically to roller 0, extends forward from wall d and partially around roller 0. assembled that a small passage remains-between roller 0 and guard d of a height to ac commodate a single sheet A., The bottom tion upon the roller 0 and the sheet will thus be taken along by such roller when the latter is rotated. From roller 0 the sheet is wound partly u on laten 6 to which it is held by bands 0 set the magazine to The parts are so sheet A of the stack rests with its front por- TOO sheets A of different widths, it is provided I with a movable transverse partition d adjustable by screws d I Upon the com letiqn of a writing a turn is given to platen F by the means hereinafter described for the purpose of ejecting the old sheet and introducing a new sheet These means are as follows: In frame a of the typewriter operator is journaled a powenshaft e,

which receives continuous rotation from an e'lectromotor or other source of power. (Not shown.) Upon shaft 6 is loosely mounted a worm-wheel e in permanent engagement with an-elongated toothed wheel or pinionwiref. The gudgeons of the latter are hung in bearings g of a slide g, which is U-shaped in cross-section, Figs. 1 and 4. One end of pinion-wire f is provided with a bevel-gear f engaging a wheel h of a spindle h, inclosed in a casing 9 forming part of slide 9. Spindle 71, is intergeared by wheels 7L2 i with a spindle i, rotatably mounted in'bearing g of easing g To spindle i is secured a ratchetwheel i engaged by a resilient finger i 'which is fastened to a perforated head i,

loosely mounted upon spindle i. The enlarged end i of head i is provided witharecess *5", adapted to receive the. usual knob or handle 5 of platen b, which is secured to head i* by clamp-screws 01 In this way the slide 9 is connected to platen b and consequently to carriage b, so as to be taken along by the same. The length of pinion-wiref is such that it Will be engaged by wheel e in all positions'of carriage. b. It will be seen that by rotating worm-wheel e (which is adapted to be coupled to power-shaft e in manner hereinafter described) platen b will also be rotated by transmission f, f, h, h, h, i, 'i, i", i and i. The ratchet connection between headi and spindle i permits the platen b to be rotated independently from the above-described mechanism at the commencement of each new line of the writing.

The means for coupling worm-wheel e to shaft e are as follows: The hub e of wheel 6' is notched, as at a to form one member of a clutch or coupling, the other member of which consists of a correspondinglynotched tube 6, slidably mounted on shaft e. Tube e participates in the rotation of shaft 6 by a pin 6 on the tube engaging a slot a of the shaft. Coupling member 6 is further provided with a groove e engaged by the forked end of a spring 7', secured to frame a by post 9' The fork j rests against the armature k of an electromagnet I", which armature is secured. to one pole of the electromagnet by a flexible metal strap k while its freev end is normally held away from the electromagnet byspring If a current is sent through electromagnet ii in manner hereinafter described, thelatter will attract armature to close the coupling 6" e so that worm-wheel 6' will rotate together with power-shaft e, and thus operate the platen, as already described.

The circuit may be closed eithermanually by a key or automatically by a perforated recbutalso to actuate the character and shift keys of the type-writer.

'erator is worked by hand a record at is simultaneously formed by a set of punches with which the operator is provided. These punches are actuated by a seriesof keys Z on the operator, which also serve to work the corresponding keys of the type-writer and do not form part of the present invention. In addition to keys Z there is pivoted to the op crater-frame a at Z an additional key which I term-the pa er-feed key. This keywhen depressed wil cause three separate operations to be performed i. e., it will,

ondly, the record to be punched, and, thirdly, an electric circuit to be closed, so as to energize electromagnet k .for operating the paper-feeding device. The record m, hereinabove referred to, passes first underneath a record-feed roller-n, then partly around a grooved rollero, and finally back over feedroller n. The rollers 'n and 0 are rotatably mounted in a block a, forming part of the operator-frame a. Above the roller n is arranged a rubber-covered pressure-roller a, so

it n will be ositively taken along. For op erating the eed-roller a I provide a swinging cross-bar p, hung in a pair of levers p and arranged directly beneath keys Z Z of the operator. The levers p are pivoted to the op crater-frame a at p and are located at both sides of such frame, (only one lever being shown in the drawings.) Upon bar pis loosely mounted a pawl q, engaging by inclined nose g a ratchet-wheel n", fast on shaft n of roller n. It will be seen that by depressing key 1 bar 19, together'with pawl l, will be lowered to turn ratchet-wheel n and feed-roller n. After the nose 9. has thus turned wheel n for the distance of one tooth n it will be pushed out of engagement with wheel a by the point of the next tooth n". Thus the wheel a and consequently record 'm, will be arrest-ed, while key 1 may be still further depressed. This further descent of key Z causes the record m to be punched in the following manner:

Block a is perforated, as at a", to accommodate a punch 1', having a head 1". The punch r is located beneath key Z and isdepressed by the last portion 9f the downstroke of the key, so as to forn the desired hole in the record. The punch is normally held in its raised position by a spring 1' en gaging its head 1' and secured to block 0/.

To operate the paper-feed, spring r extends beyond punch 1 to form a contact r arranged above a second contact s, insulated from block a, as at s. The rear end of corn tact s is secured to a contact-pieee-t, carried i by blocka and insulated therefrom, as at Z. A wire u, connected to contact-piece t, leads to one pole of electromagnet Ir, the 1 other pole of which is connected byv wire a The construction is such that when the op 'that the record when'passing between rollersfirstly, cause the record to be advanced; seccoupling e e.

erator by suitable means.

When the record is thus run through, it will see-,ese

to a batteryor other source of electricity U. The latter is in turn connected by a wire a to block c. 'The ..depression of key Z will thus close contacts r s of a circuit, the current flowing as follows: from source of electricity U through wire 'ufi, block a, spring r contacts r s, contact-piece t, wire u, electromagnet 7c, and wire it" back to source U. The electromagnet Jr has thus been energized to attract armature k, and. thereby close In this wav'worm-wheel 6 will be rotated to correspondingly turn platen J2 in manner hereinbeiore described, and thus feed the paper. Upon the release of key 7, pawl q and punch 7 will be raised, ,While contact 1' s will be opened. Thus electromagnet k is denergized to spring 9' to open coupling e, and t ereby arrest the platen b I v If it is desired to multiply the copies of the writing, the record produced as described is repeatedly run through the type-writer opautomatically feed the paper in the following manner: To block a is p voted at "0 a lever 0, having a pin 22 and a contact U v is located above grooved roller 0, While contact if is located above contact-piece t.-

The first groove 0 ofroller o is in alinement with the perforations m of record m, so that when'either of such perforations arrives b,e-,

neath pin 0* the lever Q) will drop until contact c rests upon contact-piece t. In this way a circuit is closed, the current flowing as follows: from source of electricity U through wire u block a, lever 11, .contacts' b t, wire it, electromagnet k, and wireu back to source U. In this way electromagnet 7c is energized to close coupling e e, and thus start the paper-feed mechanism.

To adapt the feed mechanism to papers having differently sized head spaces, the

holes m of record we may be made of different lengths, ,as illustrated in Fig. 11. If. a large hole passes underneath pin 12 the feed time than when a short perforation passes underneath the pin, so that in this way the feeding eriod is easily controlled by the length 0 the perforation.

It will be seen. that by my invention the record may be properly punched at the end of a writing to form a feed-perforation and that suchperi'oration subsequently serves to automatically eject the old sheet and feed a new sheet to the machine upon the completion of each writing. tion is entirelyautomatic and writings may be multipliedwithout requiring the service of an attendant for changing the sheets.
