TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Oct. *7, 1919.

Application filed November 4, 1916. Serial No. 129,461.

To all whom it may concern:

Be it known that I, GEORGE A. Sure, citizen of the United States, and resident of Ilion, in the county of Herkimer and 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 typewriting machines and more particularly to paper tables and means for mounting the same.

One of the main objects of my invention, generally stated, is to mount the paper table in such a manner that it may be moved from its normal position to a folded or substantially horizontally disposed position over the platen and in compact relation with the machine, even though the paper table be equipped with forwardly projecting side edge gages which ordinarily would obstruct the movement of the paper table to such compact relation.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings wherein reference characters indicate corresponding parts in the different views,

Figure l is a fragmentary side elevation showing the upper portion of a typewriting machine, with a paper table mounted on the carriage in accordance with my present in- Vention.

Fig. 2 is a detail fragmentary sectional view of some of the parts, the section being taken on the line w00 of Fig. 1 looking in the direction of the arrows at said line.

Fig. 3 is a vertical transverse sectional view of the construction, the section being taken onthe line g y of Fig. 1 and look ing in the direction of the arrows at said line.

Fig. 4; is a diagrammatic side View with parts omitted and illustrating the members as they appear when the paper table is in its folded position.

Fig. 5 is a like view of the same showing the parts as they appear when the paper table is in the normal or operative position.

F ig.-6 is an enlarged perspective view of fying, or materially modifying, the structural features of said machine as they now exist. It should be understood, however, that the invention may be embodied in vari ous styles of typewriting machines.

In some N o. 11 Remington machines, such for example as those equipped with a Wahl adder or cross-footer it has been customary to employ a large paper table provided with forwardly projecting side edge gages. In these machines the paper table thus equipped could not be folded down over the platen because of the obstruction ofiered by the side guides or gages and the platen. This prevented the use of the machine in dropcabinets, and also rendered it inconvenient to pack the machine in its case for shipping without first detaching the paper table.

By my present invention I provide simple I and eiiicient means for overcoming these disadvantages, by enabling the paper table to be readily swung down over the platen into compact relation with the machine.

The frame of the machine, comprising corner posts 1 and top plate 2, supports the carriage in the usual manner for movement from side to side of the machine over the top plate. The carriage comprises the usual truck designated as a whole by the reference numeral 3, and the platen frame, designated as a whole by the reference numeral t, the latter being connected to the truck by links 5 and 6 for case shifting movement. A platen 7 is carried by the platen frame 4, the shaft of the platen turning in bearings in the end plates 8 of the platen frame. These end plates are provided with rearwardly and upwardly extending arms 9 to which blocks lO are secured by screws 11. The outer end of the lefthand filler or block 10, as shown in. Fig. 6, is notched or cut-away for the accommodation of the hub 10 of a spring-pressed key 10", which in practicercooperates with other parts of the machine having no relation to my present invention and not illustrated in the drawings. Two upwardly extending fixed arms or standards 2 and 13 are secured to the inner ends of the blocks lOby screws 14 (see Fig. 2). The arms 12. and 13 andtheblocks 10 are apertured to receive a tie-rod 15 tapped at its which extend through openings in the arms 9; The tie-rod15 passes through both blocks I '10 and also throughthe hub of sa1dspringpressed key or lever 10". This tie-rod thus provides additional means for connecting the blocks to the arms 9 and for preventlng.

the blocks. from turning on said arms and also for connecting the arms 12 and 13 to the 7 blocks and preventing the arms'from turning on theblocks. A. pair of parallel links orarms 16 are apertured at their rear ends where they are received on the tle-rod 15 to v.nect sail links each of said'links 16 and provide a pivotal mounting for the links.

,Washers17 surround the rod 15 outside of V the arms 16, a washer being situated-between the associated fixed upright arm 12 or 13. Each link 16 is apertured about midway in the length thereofto receive'a"tie-rodj18 which, as shown in Fig. 2, e. :ten'd s at its ends beyond'the links to form stop,pins 19. This' tie-rod is solderedor otherwise fixedly secured in the openings in the links 16so as to rigidly conto swing together and in eflect form a pivoted frame or member of the links 16 and tie-rod'18. The stop pins 19 on this frame coast with the arms 12 and 13',-and with the blocks 10 connected there- ....with, to limit swinging movements of the frame; as indicated" in Fig. 1.

Project ng inwardly I pivot pin threaded into a tapped opening in its'link 16. The pivot pins are received in bearings 21 formed'on sheet metal bracket membersQQ'. These brackets are riveted at 23 to therear-s de of a paper table which table is designated as a whole by the referpointed end of the pin to be received ence numeral; 24:; In order to retain the paper. table in its normal position, shown in fulllines in Fig. 1, each bracket member 22 is provided with a spring-catch or latch. Eaclrcateh is in the nature of a spring finger 25 curved slightly toprovide a cam face, which in its 'co-action withthe associated pin 26 carried by the arm 12 or 13 causes the spring finger to be fiexedfslightly and the in a depression 9.5 in the spring finger. The

the arms12 and 13 and an accidental dis placement of the'paper table from its normal position around thepivotal center of the floating pivots 20 is prevented. In order to release the papertable it is merely necessary to exert sufficient forward pressure on the upper end of the paper table to overcome the pressure of the springs25 and thus unseat the pins 261 from the depressions 25 in the fingers. f To limlt the rearward of the papertable around the pivot pins 20 r .I have provided each bracket with a struck- 35" up rearwa'rdly projecting finger or stop 27,

table in place.

from the links or arms 16' are pivot pins 20; one at least of which is. in the nature of a detachable screw swinging movement which c'o-acts with the associated pin or stop 2-6.. The relation of the parts is. suchthat' when the stops 26 and'27 cosaot to limit the movement of the paper table the ends of the pins will be seated in the depressions'25 inthe spring fingers 25 and lock the paper The right-hand with a struck-up rearwardly projecting ear 3 28 to which one end of a link 29 ispivoted by a headed screw 30. This link is slotted longitudinally at 31 to receive the pin 26 on V bracket 22- is provided the arm 12'atthat'portion of the pin where it is provided'with a peripheral groove 32.

Thelink29 is split at33 so that the members on opposltesldes of the slot may be sprung.

away froni'each other. The rear end portion of the slot 31 in the link is slightly contract ed to provide oppositely disposed cam-like members 34, the distance between said'members being less than the diameter ofthe hearing portion of the pin 26 received in the slot 31. Thls provides a substantially circular bearing portion 35in the rear end of the slot,

31-in which the associated pin may be received when the sidesof the link are sprung apart by the action of the parts 34 on the pin. As soon as the parts 34L pass the pin the side members of the link will spring to-' gether, inclosing the pin within the part 35;

by spring pressure. The link thus constitutes a spring catch or latch, which 'in-its cooperation with the associated pin 26 prevents an accidental longitudinal displace ment of the llnk on the pin, and looks or holds the paper table against accidental dis- U placement from its abnormal position, represented in Fig. 4 and in dotted lines in Fig. 1. The link and pin also limit the: movement of'the paper table to abnormal'position, assisted by the stop pins 19 which limit the movement of the frame 16 -18.

' In the present instanceI have provided forwardly projecting side edge gages or guides on thef ront face of the'paper table, and which ordlnarily would interfere with the paper table being swung down from its normal position to a substantially horizontal position over the platen, and intofcompact relation with the machine. However by mounting the papertable infaccordance with my present invention theseguides andthe platen do not-interfere with or obstruct the movement ofthe papertab-le into such conipact relation. Thus it will be seen that a pair of right-angled side. edge gages 'are mounted on the front face ofthepaper table...

Each gage is designated as a whole by the reference numeral 36, and is provided with a flange 37'. The plane of this flange exllt tends at right-angles to the-plane'of the 7 paper table substantially throughout the height of the table, andthe lower end there-' of is not far from the platen. A fiat portion 38 of each gage lies on the front face of the paper table and is faced with felt at 39' where it contacts withthe table. .Each member 38 is tapped to receive the forward end of a thumb screw 39 which extends from the rear of the paper table through a slot 40 therein. A shoulder on each screw bears against'a bowed leaf-spring ll, the stemof each screw passing through an opening in the associated-spring. Each spring 41 has lugs or flanges t2 formed on the end portions-thereof for cooperation with rearwardly turned flanges 43 which form the walls of the slots 40 in the paper table. The springs are thus held against turning movement and provide resilient means for holding the guides frictionally on the paper table against accidental displacement from the positions to which they may be adjusted along the table.

It will be understood that the paper table is normally disposed in an upright position inthe rear of the platen, as shown in Fig. 5 and in full lines in Fig. 1 when the machine is in use, and directs the work sheets to the introductory side of the platen and to the bight between the platen and paper apron 4 1. 1

Should the operator desire. to fold the paper table over the platen, and into compact relation with the machine, preparatory to lowering the machine in a dropcabinet' or packing the machine for trans ortation, it is merely necessary to exert a su cient forward pull or pressure on the upper end of the paper table to disconnect the paper table from the control of the spring latches 25. As a forward and downward swinging movement of the paper table takes place around the floating pivots 20, the link 29 will be moved along the associated pin 26. This movement of the paper table is independent of the frame 1618 and will continue until the forward edges of the side edge gages reach the surface of the platen. At or about this time the sides of the link 29 will be sprung apart to receive the associated pin 26 in the bearing opening 35 therein, and further independent movement ofthe paper table on the pivots 20 will be prevented. Continued downward pressure exerted on the upper end of the paper table will be directed against the frame l618, causing a swinging movement thereof and causing the lower end of the paper table to swing upwardly around thetie-rod 15 to the position. shown in Fig. 4 and indicated in dotted lines in Fig. 1. This movement will continue until the dotted line position is reached when the stop pins 19 engage -'the arms 12 and 13 to limit a furthermovement of the frame and the paper table car ried thereby. At this time the link 29 and its pin 26 act as stops to prevent a downward pivotal movement of'the paper table around the floating pivots 20, and also act to lock directed against the pivoted frame 1618 after a given extent of independent movement has been given the paper table. It will be understood, nevertheless, that in the construction as shown and described, the side edge gages bearing against the platen assist in causing the pressureexerted against the paper table to swing the-frame 16-.-18 to the position-shownin Fig. 4 and in dotted lines in Fig. 1; the paper table operating at this time as a lever fulcrumed against the platen at the points of contact of the side edge guides therewith. It may be desirable therefore to'form each member 37 of the guides with .an off-set ear where it contacts with the platen in order to present a fiat surface for contact with the platen instead of an edge of each part 87.

To return the paper table to its normal position, it is merely necessary to raise the upper end of the paper table, now presented foremost to the operator, and at this time the spring link 29 will exert sufiicient force in its engagement with its pin 26 to cause thepressure exerted against the paper table first to swing the frame 16l8 and return it to normal 'position, where it is arrested by the pins 19. -This insures a restoration of the frame comprising the links 16 to normal position before the independent movement of the paper table around the pivots 20 takes place. Continued pressure will cause the spring link. 29 to bedisengaged from the pin'26 and enable the paper table to receive an independent pivotal movement on the pivotpins 20 back to normal position, where the pins 26 will engage the spring fingers 25 and lock the paper table against accidental displacement from such'position and will also preventany swinging movementof the frame 1618.

It will be understood that the paper table in its movement from and to normal position receives a pivotal movement around two centers, one around the floating pivots 20, and the other around the pivot or tie-rod or fixed center 15; that in the movement of the paper table from its normal working position into compact relation with the machine, the lower end of the paper table will receive an upward swinging movement when the paper table is swung down; that the effect of this movement is to elevate the point of pivotal connection (20) on which the paper table swings; that the pivots 20 are in the nature of floating pivots on which the paper table is mounted for pivotal movement' independently of the frame 16718;

that stops/29 and 26 and 26 and 27 limit this. independent movement of. the paper table,

whereas the stops 19 and the parts which coact therewith limit the swinging movement. of the frame or member l618;that spring locking means are provided forholding. the

paper table against accidentaLdisplacement from either ofthe. extreme positions to which it maybe moved; and that theselocking means operate automatically.

lVhile' a paper table mounted in accordance with my present invention is available for use, and particularly advantageous,

when side edge gages are employed onthe -front face of the paper table, itshould-be understood that myinvention is not restricted to such a construction and that. various changes may be made without departing 20 from-the invention.
