ASSIGNOR, BY MESNE ASSIGNMENTS, T0

UNION TYPEWRITER COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Be it known that I, WALTER J. BARRON, citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of Kingsand State of New York have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to paper feeding mechanism for t-ypewriting machines and has for itsp'rincipal object to provide improved releasing mechanism for releasing or throwing off from the platen the various paper feeding andcontrolling devices which cooperate therewith.

More specifically the object of my invention is to provide for throwing off or releasing at a single operation the main and secondary feed rollers, the paper deflector, the card guide of a typewriting machine such as the No. 10 Remington typewriter; and also to provide for the release of the devices aforesaid at a single operation without interfering with the usual releasing devices for the paper fingers which usual releasing devices operate eseparately and'independen'tly of each other and of the other devices aforesaid.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims. My invention is shown as applied to a.

machine generally resembling the No. 10

Remington typewriter but various features of said invention may be adapted to other. styles of writing machines.

In the accompanying drawings which show -one form of my invention, Figure 1 is a fragmentary front elevation showing theplaten and carriage of a No. 10 Remtoget-her with various devices cooperative with said platen and carriage. Fig. 2 is afragmentary side elevationpartly in section of Fig. 1 Fig. 3 is a view. similar toiFig. 2 but omitting some of the parts shown therein and showing other parts in diiferentrelationships.

As shown in the various views, the-platen frame or carrier comprises end plates 1 connected by :aflower cross bar 2 and an upper Specification of Letters Patent.

ings for a rotary cylindrical platen 4. The

platen frame is mounted on a truck '(not shown) and is adapted to, shift up and down on said truck to change case, the shifting devices comprising a shift rail 5 on which runs a roller 6 mounted on the platen frame. a

The platen is equipped with paper controlling devices which are preferably of the construction found in the No. 10 Remington machine. Said devices comprise both a main feed roller composed of sections 7 mounted on a shaft 8 and coiiperate with the platen at the rear lower side thereof, and also a secondary feed roller comprising sections 9 mounted on a shaft 10 and cotiperating with the'platen at its-forward lower side. The shafts 8 and 10 bear in the opposite arms of rocking levers or carriers 11, there being two such levers one at each end of the platen. Each lever 11 is pivoted at 12 to the forwardly extending arm 13 ofa three-ar1ncd supporting lever, said supporting lever further comprising an upwardly extending arm 14 and a downwardly extending arm 15. Each three-armed lever is pivoted on a rod 16 which extends length wise of the machine and is secured near its ends to-an L-shaped bracketcomprising a forwardly wardly extending arm 18, the arm 17 terminating at its forward end in a downward extension 17' which is secured by a screw 19 to the cross bar 2 underlying the platen. The arm,15 of each supporting lever has secured to it one end of a draw spring 20, the

other arm of said draw spring being secured to the bar. 2, the draw springs acting through the t-l'iree-armed levers and the rocking levers 11, and serving normally to maintain the main and secondary feed-rollers in cooperation with the platen or the paper thereon. Also pivoted on thelrod 16 are forwardly extending arms 21- which pivotally support at 22 a paper extends partly around the rear and under side of the platen between the two sets of feed rollers and is formed with openings for the feed roller sections.

The paper deflector is normally maintained in spring-pressed cofiperation with the platen and is releasable by the arm 15, as shown in the No. 10 Remington machine. This construction of the paper deflector and extending arm 17 and-an up defiector 23 which rateatetiaane as, rare.

The rock shaft is manually controlled by an arm or release key 25 fixed to it near its lefthand end and is also provided with a restoring spring 26 which. coils around the rock shaft and is secured at its ends to pins 27 and 28 fixed respectively to the arm 25 and the lefthand end plate 1. Fixed to and depending from the rock shaft 24 are fingers 29 one behind each arm 14 and cooperative with said arms 14., when the release key is operated, to rock the three-armed levers against their springs 20, thus releasing the feed rollers or moving them from-the normal position (Fig. 2) to the abnormal posi At the same time, as shown in the machine, the paper deflector 23 is released. The springs 26 and 20 assist to restore the parts to normal position when backward pressure is removed from the reing bracket which is bar 2 of the platen. frame by screws-36. The

Other paper controlling devices or paper fi'ng'ers cooperate with the platen at the front side thereof and are preferably like- .the paper fingers shown in the No. 10 Remington machine and in the pending application of George H. Smith, Serial No. 526,559, filed November 6, 1900. 'The paper fingers each comprisean upright portion or finger 30 of sheet metal preferably,

said finger carrying at its upper end a prcssure roller 31 which cooperates with the front of the platen above the printing line, which is along the middle of the front face. At its lower end each finger is broadened by a lateral off-set 32 and is curled or bent around a rectangular rock shaft There are two rock shafts one for each paper finger so that the paper fingers may be separately released. Each rock shaft 33. hears at its outer end in 'thle adjacent end bar 1 of the platen frameand at its inner formed. at the top of an upright arm comprised in a U- shaped supporting bracket. There are two arms 34 spaced apart and connected zit 111611 lower ends by a cross-bar 35, the two arms 34: and the arm 35 constituting said supportsecured t'o' the front paper fingers are slidable along their respec tive supports or rock shafts to cooperate with paper of different Widths and ea h rock shaft is manually controlled by a hey i or arm 37 which is secured to the end of its associate rock shaft outside the adjacent v 37 is provided with an upwardly and for.

wardl y extending finger piece or key 40 which on being pressed downward overcomes the associate spring 38 and rocks the shaft 33, thus releasing the associate pressure roll 31, moving the same from normal position (Fig; 2) away from the platen to the position shown in Fig. 3.

The main and secondary feed rollers and the paper fingers, it will be observed, are mounted on the platen frame or carrier and travel with the platen during its letter spaci'ng movements. The No. 10 Remington machine is further equipped with a relatively stationary paper controlling or guiding device or card guide 41 which comprisesdownwardly extending flexible arms42, said arms being secured by screws -13 to fixed to the shift rail 5. It will be seen that the device 11 remains stationary during the letter space movements of the platen, always ljearing the same relation with respect to the printing point. The device 41 is not my invent-ion and is not claimed per so by me.

As thus far described and as shown in the machine, the releasing of the feed rollers and paper deflector does not affect the paper fingers nor the card guide While onthe other hand the releasing of either paper finger30 does .not affect the other paper finger nor any of the paper controlling devices aforesaid. No provision is made in the machine for releasing the card'guide 41 other than by pulling it away by hand from the face of the platen. In practice it is sometimes desirable to simultaneously release all of the paper controlling devices .abovenamed so that a. free and unobstructed way'for the paper may be afforded all the way around the platen. By my invention I provide for simultaneously releasing all the paper controlling devices and this I accomplish without affecting the devices heretofore provided for separately releasing certain of said devices.

My invention as hown in the present instance cou'iprisos a bar or-rod 45 which extends lengthwise of the machine forward-0f the platen, said bar 45 being arranged above the rock shafts 33 and behind the paper fingers and card guide. The bath? is provided near its ends with tabs or ears 4 3 abracket 44.

paper fingers 30.

which bear 011 rounded portions 33*" of the rock shafts 33, thus providing a pivotal mounting of said rod 45 on the rock shafts. The bar 45 is angular in cross section as shown in Fig. 3 and is adapted to cooperate with the back of the card guide 41 and with the backs of depressions 30 formed in the Through such cooperation the paper fingers and card guide are adapted to be simultaneously released or swung away from the platen to the positions shown in Fig. 3. In order to turn -the bar on its pivot to effect such release of the paper fingers and card guide, it nyay be pulled forward by hand, but preferably I provide devices which are controlled automatically preferably from the release key 25, so that by the operation of said release key the feed rollers 7 and 9 at the under side'of the platen are released and at the same time the devices 31 and 41 at the front of the platen are released. The releasing devices for the bar 45 comprises extensions or fingers 47 which curve rearward and downward from the ends of said bar 45. As shown in Fig. 1 the bar 45 extends at its ends-beyond the end plates 1 and the fingers 47 are outside vsaid end plates. The weight of the extensions tends normally to turn the bar 45 rearward but said bar is maintained in normal position by stop pins 48 which project laterally inward from the end plates 1 and cooperate with the rear sides of the ears 46. The ends of the fingers 47 are rounded and are adapted to be engaged by the forward end portion of releasing arms 49, of which there are two. Said arms are secured to the outer ends of the rock shaft 24 by screws 50. The releasing arms 49 are arranged outside the adjacent end plates 1 and extend downward and forward, being normally separated from their associate fingers 47 as shown in Fig.2.

When the release key 25 is pressed rearward, rocking the shaft 24 and releasing the feed rollers 7 and 9, the rock shaft 24 as it turns, rocks the releasing arms 49 upward and toward the end of its turning movement said arms are' brought, into contact with the fingers 47.- After such contact said arms 49 during further movement swing the fingers 47 upward and rock the releasing bar 45 forward on its pivot. The forward movement of the bar 45 bpings it into operative contact with the paper fingers 30 and card guide 41, said bar thus acting to release the paper fingers and pressure rolls 31 and to swing the card guide 41 to the released position shown in Fig. 3, the flexible fingers 42 yielding sufficiently to permit of this movement of the card guide. \Vhen pressure on the key 25 is released the card guide is re stored by the inherent spring of the arms 42, and the pressure rollers 31 are restored by the springs 38; while, of course, the main and secondary feed rollers and paper deflector are returned in the usual way.

It will be seen that by the use of my invention all the paper controlling devices including the main and secondary feed rollers, paper deflector or apron, paper fingers and card guide may be swung away from the platen or released at a single operation, thus providing a clear passage around the platen for the paper.

It will be observed further that by present invention 1 provide for automatically releasing the paper fingers simultaneously, the automaticmeans in the present instance comprising connections between the releasing bar 45.and therock shaft 24, said rock shaft being operative by the key 25 and vcarrying releasing devices for the main and secondary feed rollers, the main feed roller in the present instance being at the introductory side of the platen, that is, at the lower rear side thereof, while the secondary feed roller is arranged below the printing point and between the same and the main feed roller. The release key 25 also operates to turn the two rock shafts33 automatically to release the paper fingers and also operates to releaseautomatically the paper guiding device or card guide 41, the means by'which this automatic release is effected in the present instance being the releasing bar 45. It is further to be noted that the two rock shafts may be turned independently of eachother to release their associate paper fingers and that this independent turning of the rock shafts is also independent of the releasing bar 45 and of the releasing mechanism for the feed rollers.

., By my present invention I provide simple and effective means for completely freeing the platen from the various paper controlling and feeding devices which normally. cooperate with said platen; and said means have been applied to the machine in thepresent instance without interfering with the normal operation of the other devices with which the machine has been hitherto equipped.
