Specification of Letters Patent.
Patented July 25, 1916.
Application filed Ap1'i127, 1916. Serial No. 93,862:
lie it known that I, Airmen ll. Snrri citizen of the lilnited E tates, and resident of the borough of lilanhattain city of New Y rk, in the county of New York and. State of New York have invented certain new and useful lmproven'ients in iilvpedl riting Machines, of which. the .l'ollowinr, is a specification.
My present invention relates partieuhirly' to paper controlling, liuldn and :hleding mechanism for typewritinn' iii-.u-hincs and its general. object is to provide inn 'nroved mechanism ot' the character s 'iecilied.
More specifically stated, one object of the invention is to provide an in'iprovcd end gage and another object is to provide an improved pressure device or paper finger contrivanee. J
Another object is to improve certain features in the construction disclosed in the patent to Phelps No. 1,100,442, granted. June 16, 1914.
To the. above and other ends my invention consists in the features of construction, combinations of devices and anangements of parts to be hereiinifter described and partlc-lllarly pointed out in. the claims.
In the :u.-com nin ving drawings Figure l av fragmentary end view, partly in section oi the upper portion of a No. 11 front-strike Remington typewriting machine embodying my invention. l is'. 2 is a fragmentary perspective view of one of the end stops or gages and associate parts. Figs. 3-5 and i are end views. partly in section, showing' the end stop and associate parts in dili'erent positions. Fig. 5 is an end View, partly in section, showing the relationship of the parts when certain of the feed roll devices are released. Fig. (l is a fragmentary front elevation, partly in section showing the platen carriage with my .in'iprovcments applied thereto. Fig. T is a. fragmentary perspective view of my improved pressure device or paper finger contr-ivance. Figs. 8 and 9 are detail views of certain of the feed roll. devices.
Referring first to Figs. 1 and (3 the main 1 nine efthe machine is shown as co1npris- -pression tionary grooved guide rails 33 and 4 with ins; a top platcl, having a. trough or de- Ahore the top plate are stawhich cooperate through rollers with the grooved front and rear hars numheren respectively (3 and T oil. a reel; ular carriage truck which further comprises end bars 8. ii platen frame or carri r comprisi" lfill'b or plates 9 and a connecting or bridge piece 10. in the present ii tance, rigidly mounted on the carriage truck as in the lhelps patent aforesaid. The carriage comprising: said truck and said platen irame provides a support for a rotary platen 11 which is arranged above the cross bar 10. The cross bar 10 is provided at its rear side with upstanding lugs 12 which are arranged. at intervals lengthwise of the bar and pro vide a hearing: if'or a hollow rod or rock shaft 13. l lxteiuling through the hollow shaft 13 is a release rod. or we r shaft M which bears at its ends in the end bars 9. At its left-hand outer end the rock shaft 142 is provided with a crank arm 15 which is pivotally connected with the lower end of an eccentric strap 16, the upper end of said strap cooperating with an eccentric 17 provided with a finger piece or key 18 and pivoted at 1.9 to the end bar 9. Bearing on the hollow shaft 13 are pairs of lnmger arms 20, each pair carrying a shaft 21 on which are mounted the sections 22 of feed rollers. Springs 23 connected to the hanger arms 20 and anchored to the cross bar 10 tend to keep the feed rollers 22 in operative relationship with illle' llllllel'Slde of the platen 11. The feed rolle'rsiQimay he thrown off I,
. effect a rocking of the shaft 13. This rocking or turning: movement of the shaft is in dependent of the shaft 1.4 and is trans mitted to the hanger arms 20 by fingers 26 fixed to the rock shaft and. provided with lateral pins 27 which overlie said hanger arms. The relationship oi: the P311325 and '24 when the feed rollers 22 are operative is shown in Fig; 1. By moving the carriage leftward far enough the lower end of the device 24 engages with and isoperated by the wheel 25, rocking the shaft 13 and throwing off the feed rollers 22 as will be understood from Fig. 5. The point in the carriage travel at which the feed rollers 22 are automatically 7 thrown oif as described depends upon the location of c the roller 25 which may be varied. It will be understood 8 .that this automatic throw-off of the feed rollers occurs during movement of the car- -riage in either direction whenever the part 24 operatively engages with the roller .25, and that as soon as the part 24 )asses out of engagement with the roller 25 t 1e feed roll ers will be restored to operative position by thesprings 23. ;-.The feed rollers 22 are between or intermediate terminal or marginal 7 feed rollers 28 which are controlled by the release shaft 14 which in turn is controlled by the key 18.
The construction of the rollers 28 and their mountings will best be understood from Fig. 2.
Each terminal roller-28 comprises a sheath 7 29 of rubber or the like and'a core 30, the
core projecting outward beyond the sheath and having reduced end portions 31 which bear in parallel arms 32 of a U-shaped support or hanger 33 that further comprises a connecting cross piece 34 joining the arms 32. The arms 32 have perforated bearing portions and the outer arm-of each terminal hanger 33 bears on therock shaft 14 .while the inner arm bears on the shaft 13as will be understood from Figs. 6 and 8, the
latter being an enlarged sectional view of the left-hand hanger 33 and associate parts taken through and lengthwise of the rock shaft 13. .Draw springs 35 connect the hangers 33 with the cross bar 10 andtend to keep the feed rollers 28 in cobperativeengagement with the platen. The terminal feed rollers 28 are in line with the inter:
'- -mediate feed rollers 22, both sets being i outer hanger arms 32, the construction being housed by the bar 10, but the rollers 28 are not controlled by the automatic devices 24 and 25. Said rollers 28 are releasable by vfingers-36 fixed to the rock shaft 14 and provided with lateral pins 37 which overlie the such that when the key 18 is pushed rearward from the Fig. 3 to the Fig. 4 position the pins 37 will operate on the h.ngers 33 to release the terminal feed rollers.
" lars 38 fixed to the rock shaft 14 prevent inward displacement of the hangers 33 lengthwise of said shaft. Means are also provided for releasing the intermediate feed rollers 22 when the feed rollers 28 are released by the key'18, said means comprising two collars 39 (Figs. 6, 8 and 9), which collars are fixed to the rock shaft 14 just beyond the ends ofthe, hollow shaft13. Each collar 39 is undercut to provide shoulders 40 and the end portions of the shaft 15 are correspondingly out to provide underlying shoulders 41. The normal relationship of these shoulders is best understood from Fig. 9 which is an enlarged sectional view taken transversely through the" shaft in Fig. 8 and looking'inward toward the middle of the ma- 7 When the key 18 1s swung rearward chine. from the Fig. 3 to the Fig. 4 position the forward shoulders 40 on the collars 39 engage with the underlying shoulders 41 on the shaft 13 and turn said shaft to effect a;
1 movement of the shaft 13 under an actuation of the automatic devices 24 and 25' without affecting the collars 39 and the shaft 14. A paper table 42 is supported on the platen frameabove and to the rear of the platen and below the paper table is a paper apron or deflector 43 which curves downward behind and under the platen terminating below the printingline at the forward side thereof. The apron 43 is secured to blocks 44 which are rotatable on the shaft 13. The .feed rollers co6perate with the platen through openings 45. in the paper apron, the outer or end openings accommodating not only the terminal feed rollers '28 but also the novel end stop devices next to.
The end stop devices or gages 46 are preferably formed of sheet metal and are of a shape best shown in Fig. 2. Each sheet metal plate 46 is provided with an upturned forward end 47 forming the end stop proper. At its sides the plate 46 has rearwardly extending fingers 48 which are curled loosely around the extended portions of the core. or axis piece 30 and thus provide a loose pivotal connection between the end stop and the feed roller and its 1 hanger or support 33. At all times theend stops rest forward of their pivotsagainst tli'eiipstanding pointed end 10 ofgthecross bar 10 which provides a fixed abutment that is in the nature of a fulcrum for the end stop devices. The normal or inoperative position of these end stop devices is shown inFigs. 1 and 3. When the release key 18 is swung backward to the Fig. 4 position to release all the feed rollers the rear or pivotally connected end portions of the stop devices 46 are swung downward and backward, causing said devices to slide over the abutments 10 and elevating the forward portions or stops proper 47 until said stops are brought into operative relationship with nioemi the platen as shown in. Fig. a. With the parts in this relationship a wide sheet may be inserted into the machine and accurately positioned lengthwise by the aid. of the steps 47, after which the release key is returned, causing the restoration of the rollers to working position and withdrawing the stops 47 which slide forward over the abutment 10" and also fulcrum on the same. The stop devices, it will be noted, may be regarded as levers of the first order. It will be understood that during endwise movements of the carriage that may cause automatic: releasing of the intermediate feed rollers the end stops 47 will not be affected, the construction being especially designed for use with sheets of ditlercnt widths, 2'. 0., wide sheets and sheets somewhat narrower than the wide sheets, the latter being controlled primarily by the terminal feed rollers and the end stops. My improved end stops are simple in design and positive in operation, dispensing with the use of springs and com plicated parts which are liable to get out of order.
Uther novel paper controlling devices are provided, said devices con'ip ising paper fingers which are preferably in skeleton form and cooperate with the front face of the platen, said paper fingers being mounted on arms which are adjustable on and extend rearward from a spring-pressed rod which may berocked to throw the paper fingers simultaneously upward and t'm'ward away from the printing face of the platen. Referring particularly to Figs. 1, 6 and 7, 49 is a rod or rock shaft that extends lengthwise of the platen and is arranged some distance in front of its printing face, said rod hearing at its ends in brackets 50 rigid with the front bar 6. The upper face of the rod is flattened as indicated at 51. Collars or hubs are arranged on the rod, two-collars being shown in the present instance, each collar being provided with a thumb screw 53 which coiiperates with the flat face 51 to hold the hub in adjusted position lengthwise of the rod. Rigid with the hub 52 and projecting therefrom is an arm 54: which is provided at its rear end with an angular extension or inwardly projecting stub rod or shaft the stub shafts extending parallel with the platen axis and carrying each a. paper finger 56. Said paper finger is in the present instance made of wire bent to the shape of a Y, the upper ends or branches being secured in the end portions of the associate stub shaft. The paper linger extends downward across the printing line on the front face of the platen and its lower contracted cud projects below the upper-edge of the paper apron 43. Arranged on each stub shaft and confined between the arm 56 and one of the branches of the paper finger is a pressure device or roller 57. The pressure. devices or paper finger contrivances, comprising the paper fingers 56 and the pressure rollers 57 conlined within them, may be adjusted lengthwise of the platen toward and a wry from ach other by loosening the thumb screws 53 and pushing the arms 54. inward. or outward. Said contrivanccs are normally maintained spring pressed in cooperative engagement with the platen by draw springs 58 which are anchored to the brackets 50 j and are also connected to arms 58) rigid with the we}; Sh ft 4%). By pulling upward on either of the arms 5% the paper lingers may be simultaneously released, being swung upward and forward away from the platen as shown by dotted lines in Fig. 1. l hen they are down in engagement with the platen it will he observed that the entire front and upper face of the platen between the paper fingers and the upper edge of the paper apron it is left entirely free and unobstructed.
Various changes may be made without departing from my invention.
