'I'YPEWRITING MACHINE.

. Specification 'of Letters Patent.

Patented Jan. 10, 1922.

Application filed December 26, 1919. Serial No. 347,473.

To all whom it may concern.

Be it known that I, Jesse A. B. SMITH, a citizen of the United States, residing in Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and more particularly to machines such as that disclosed in the patent to C01'- nelius B. Corcor'an, No. 1,105,184, dated July 28, 1914.

In said patent, use is made of a carriage of considerably greater width than usual, having a platen of such length that when the carriage is moved to one of its limiting positions, a sufficient length of the platen to receive the work-sheet will extend to one side of the printing point to enable a guide plate or deflector at the side of the machine to be utilized in directing a work-sheet to the front of the platen.

In carrying out this invention, the usual rear feed-rolls at the bottom of the platen may be omitted, and the levers usually contro ling such rear feed-rolls may be utilized to control the position of a paper-guide pivoted at the rear of the platen, provision bein made of springs urging the front feedro ls and paper-guide toward the platen, and a cast-off mechanism to release said front feed-rolls and the paper-guide.

In order to guide front-inserted worksheets downward at the front of the platen, and to prevent the downward passage of such sheets in front of the forward edge of the paper-guide, a front guide plate or deflector the length of which is commensurate with the width of the work-sheets to be inserted, is pivoted on one side of the machine forward of said platen, so that it may be swung to and from a position to co-operate with the'platen and overlie the front edge of the paper-guide when the latter is in released position.

As herein disclosed, the deflector is pivoted to swing about an axis beneath the same, and a spring is attached to the deflector and to a fixed part of the machine, in such manner that when the deflector is moved in either direction (that is, away from either of its extreme positions), it will be opposed by the spring until it has passed the middle point of its path when the spring will become effective to assist in completing such movement.

It will be understood that before inserting a work-sheet from the front of the machine, the feed-rolls and paper-guide are to be released or withdrawn from the platen and the guideplate or deflector then swung to the rear, so that its rear edge will overlie the forward edge of the paper-guide. In view of this condition, provision is made of a cam member on the deflector near its front edge, having a dwell ortion throughout the greater part of its ength to co-operate with the carriage when the latter is traveling therepast to maintain the deflector in its forward position, and an inclined portion at its outer end, so that when the carriage is moved to its limiting position the deflector may be shifted to the rear, and upon movement of the carriage away from its limiting position the deflector will be swung to .the front.

In order that the inner edge of the sheet may pass readily between the adjacent wingscale and the platen when the carriage is shifted to a position for printing after the insertion of the sheet at the front of the platen, the outer end of the wing-scale may be given a slight outward'flare, and the deflector may be provided with a projection at its inner end and at its rear edge, so as to press the inner edge of the work-sheet closer to the platen to insure the passage of the inner edge of the work-sheet behind the wing-scale when the carriage is shifted to a position to enable typewriting on the sheet inserted.

Suitable means may also be provided for gaging the position of a work-sheet inserted from the front.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a fragmentary plan view of a typewriting machine with my invention ap plied thereto.

Figure 2 is a side view, partly in section, showing the parts in their normal positions.

Figure 3 is a View similar to Figure 2,

"4, extending from one end of the platen frame to the other at the rear, and a connecting rod 5 extending from one end of the platen frame tothe other below the platen. Said platen frame 3 forms part of a carriage 6, which is supported at the front by means of a roll 7 thereon, projecting into a recess 8 in a front rail 9, and at the rear by a rail 10. I

Secured to bar 4 by means of screws 11. are brackets '12 having loops' 13 in which a rod 14 is supported. Pivotally supported .on this rod is a paper-guide 15 extending downwardly and forwardly to the platen around which it curves to the front thereof, forming a paper-table at the rear of the platen and an apron beneath the platen. Also mounted on rod 14 is an extension l6 of the paper-gnide-normally extending in an upward and rearward direction, and so supported on rod 14 that it may be swung in a forward direction to give access to the c back of the .machlne.

Said extension 16 may be provided with apertures 16 to render the screws 11 accessible when the extension 16 is in its normal position. Inor'der to support the paper-guide 15 on the rod 14, loops 17 are pressed outwardly from the paper-guide 15' to receive the rod 14, thus furnishing a pivotal support for said paperguide 15. V. The connection of the extension 16 with the rod 14 is obtained by means of tongues 18 extending from the forward edge of the extension, and forming loops bending around said rod 14.

Mounted on rod 5 are levers 19, supporting in open bearings at their forward ends a shaft 20 on which are, mounted one or more front feed-rolls 21. Pivotally mount-' ed on brackets 22, fixed on said rod 5 and extending rearwardly therefrom, are levers 23, the rear ends of which pass between the paper-guide 15 and the offset ends 24 of strips 25 secured to sald paper-guide, the forward ends of levers 23 being bent so as to pass beneath pins 26 on levers 19 and below and upward at the front of rod 5. A spring 27 interposed between an offset 28 on eachof levers 19 and a fixed part' of the platen carriage, urges the front rollsi21 toward the platen and the paper-guide15 to its normal position.

When it is desired to release or cast off the feed-rolls either for the introduction of shaft 30, and, by means of an arm 31 thereon and a link 32 connecting said arm 31 with an arm 33 on a release or cast-ofi' shaft 34, rocks said cast-off shaft from its Figure 2 position to its Figure 3 position, so that the flat faces 35 on the cast-off shaft no longer contact with the levers 23, which are now engaged by the outer portions of said shafts, thereby casting off the feed-rolls 21 and concomitantly releasing or withdrawing downwardly the paper-guide 15. It will be seen that when the cast-olfshaft 34 is turned into its Figure 3 position, the feedrolls 21 and paper-guide 15 will be locked in their released or withdrawn positions.

In order to guide the lower edge of a work-sheet to be inserted at the front ofthe platen downwardly at'the rear of the front edge of the paper-guide 15 and to prevent passage of the work-sheet in front of said paper-guide 15, provision is made of a guide plate or deflector. 36 having downwardlyturned ears 37, which are pivotally supported by means of shouldered screws 38 on the turned-back ends of the bracket 39, of which the inner end 40 is secured to the righthand frame of the machine by means of screws 41.

For the purpose of assisting in maintaining the outer end of said bracket 39 in 'posi-- tion, provision is made of acurved brace 42 connected with the machine frame near the front by a screw 43, and at its other\ end by a screw 44 to said bracket 39.

As shown in Figures 2 and 3, the forward and rearward limiting positions of the deflector 3.6 are determined by engagement of said deflector with either the front or the rear edges of the offset'ends of bracket 39. The deflector 36 may be maintained in either forward or rearward position. Provision is made of a spring 45 connected at its upper end to an car 46 on the deflector 36, and at its lower end to a pin 47 on the bracket 39. A finger-piece 48 is secured, by means of the right-hand screw 38 and a pin 48*,

to the adjacent ear 37 of the'deflecto r 36 to move the deflector from either one of its limiting positions to the other. i

In practice, the paper-guide 15 and feedrolls 21 are first released or withdrawn concomitantly by depressing the finger-piece 29 and then, by raising the finger-piece 48, the deflector 36 is swung to the rear to overlie and co-operate with the forward edge of the paper-guide 15, as indicated in Figure 3. In this effective or sheet-guiding position of the deflector 36 its rear margin overlies or overlaps upon the forward edge of the depressed paper-guide 15, thereby effectually preventing the possibility of the bottom edge of the downwardly-inserted work-sheet passing at the outside of or catching upon the paper-guide 15. In order to prevent shifting of the deflector 36-t-o its rearward position before the carriage has been moved into position to co-operate with the deflector, and to insure withdrawal of the deflector when the carriage is moved away from its limiting position, provision is made of a cam indicated in general at" 49 and comprising a dwell portion 50, in the form of an upstanding ledge extendin along the greater portion of its length, and an inclined portion 51 at its outer end. Should the carriage 6 be moved to the left from its right-hand position while the deflector 36 is at its rearward or effective position, the carriage end will engage first the inclined cam portion 51 and then-the dwell portion 50, thereby moving the deflector 36 sufficiently forward that such forward movement to the fully ineffective position of the deflector 36 will be completed by its spring 45. It will be evident that, when the right-hand end of the carriage overlies the dwell portion 50, movement of the deflector 36 to its rearward position willbe prevented. Since also the right-hand end of the carriage may ride off the inner end of the dwell portion 50, it may be desirable to providean inclined portion 52 in order to prevent inconvenience to the typist and damage to the machine which might otherwise result from the impact of the carriage frame against the inner end of the cam, in case the deflector 36 should have become moved to its forward position. case, the carriage end will override the inclined cam portion 52 and dwell portion 50 and will impart suflicient forward movement to the deflector 36 that its spring 45 can complete this movement to the fully ineffective position of the deflector 36.

After bringing the platen to the proper position and casting off the feed-rolls and thepaper-guide, the deflector 36 may be swung to its rearward'position. A worksheet may then be introduced at the front of the platen after gaging the inserted sheet by means of a forward or leading-edge gage 53at the top and a side-edge gage 54 at the inner end of the table 55. which, when in position for use, is substantiallytangential to the platen.

Said table 55 is supported on arms 56 rotatably mounted on a rod 57 journaled in brackets 58 on the platen frame, said arms 56 being normally held against turning on rod 57 by means of cylindrical keys 59 pressed by leaf springs 60 into grooves in the rod. The table 55 may be swung out of its operative position by means of a finger-piece 61 fixed on'said rod 57. said In such' It should be understood that, in case the deflector 36 is swung to the rear before the release of the feed-rolls 21 and the paper-.

guide 15, the rearward edge of the deflector will obstruct the movement of the forward portion of the paper-guide to its released position. y

In order to insure the proper introduction into the writing field of a work-sheet,

inserted at the front of the platen, the usual wing-scale 62, on the side adjacent the deflector 36, is given a slight flare away from the platen at its outer end, and provision.

is made of a cam-projection or cam-member 63 at the rear edge of the deflector 36 and at the inner end thereof, the cam-member 63 pressing the inner edge of the inserted sheet close to the platen, as this edge of the sheet passes this cam-member, so that it will readily pass under the flared outer end of the wing-scale 62.

After the insertion of a work-sheet at the front of the platen has been completed, the deflector may be moved to its forward position, by depressing the finger-piece 48, and the finger-piece 29 returned to its normal or raised position, to permit the feedrolls 21 and paper-guide 15 to return to their effective positions. Thesprings 27,

urging the feed-rolls 21 and paper-guide .15 to their normal positions, may be of suflicient strength so that, upon restoration of finger-piece 29 to its normal position, the forward portion of the paper-guide 15 will be thrown up with sufficient force to swing the deflector 36 to the front, sufficiently to enable spring 45 to complete the forward movement of the deflector to its forward limiting position.

In Figure 4 is shown a deflector 64 which may be used in place of deflector 36. Said deflector 64 is stationary and consists of a plate having its forward edge down-turned to form a concave portion 65 to receive the forward edge of the paper-guide 15 when the latter is released, the parts being so related that there is no danger .of passing the lower edge of a work-sheet, being introduced from the front, in frontof theouter side of the paper-guide 15, nor of the forward edge of a worksheet, introduced from the rear. catchingon said deflector 64..

This machine may be used for typewriting bills or other forms on which f'a small amount of printing iis effected, a.-'carbonbill 67 tobe typewritten being introduced from the front. Suitable means. such as rolls 68, shown in dot-and-dash lines on Figure 2, may be provided to hold the carbon sheet and the record sheet in position when the paper-guide and the feed-rolls 21 are released, If'desired, a plurallty of work- Variations may be resorted to within the scope of the invention, and portions of the im rovements ma be used without others.
