EDWIN E. BARNEY, 0F SYRACUSE, NEW YORK, ASSIGNOR TO THE IVIONARCH TYPE- WRITER COMPANY, OF SYRACUSE, NEW YORK, A CQRPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, EDWIN E. BARNEY, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- .Vriting Machines, of which the following is a specification.

My present invention relates to paper feeding mechanism for typewriting machines, and particularly to leading edge stop devices of such machines.

The main object of my invention is to provide improved devices of the class specified.

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 present invention is an improvement on the construction shown in my Patent No. 935,57 5, granted September 28, 1909, and the specific object of the present improvements to simplify the prior patented construction and to enable the stop devices to be operated more readily and conveniently. In the present construction, as in my prior patented construction, the leading edge stops are pivotally mounted and are constantly spring pressed toward the platen but are normally held away therefrom in a predetermined position by a stronger spring which is controlled by the release key of the machine. WVhen the release key is operated separately and alone, the leading edge stops-move only a short distance toward the platen from normal position, said stops being then arrested by an obstruction which can only be removed to permit further movement of the stops to the platen by the actuation of a hand device separate from the release key and operative independently thereof. In the patented construction this separate device is a push button which is behind and below the platen and which operates to move endwise the rock shaft carrying the leading edge stops, the leading edge stops themselves participating in the endwise movement of the rock shaft. In the present instance I have replaced the push button by a hand lever which is provided with a finger piece arranged in proximity to the regular release key so that the release key and the special finger piece may Specification of Letters Patent.

single operation by the left-hand of the operator whenever it is desired to bring the leading edge stops into action. Moreover, the actuation of the special finger piece, instead of moving endwise the rock shaft and the end stops thereon, merely moves an obstruction out of the way of said rock shaft so that the prior slidable mounting of the rock shaft may be dispensed with.

My invention will be more particularly described in connection with the accompanying drawings wherein,

Figure 1 is a fragmentary bottom plan view of the platen carrier and platen of a Monarch typewriting machine embodying my invention. Fig. 2 is an end view of said platen carrier and platen showing the parts in normal position. Fig. 3 is a fragmentary perspective view showing parts of my improvements and their mounting on the platen carrier. Figs. 4-, 5 and 6 are vertical sectional views transverse of the platen carrier and platen, the paper feed releasing mechanism and my improvements appearing in different relations in the different views.

Referring to the drawings, the platen carrier which comprises a rear bar 1 and end bars 2 and 3 carries a platen 4E mounted on an axle 5 and provided atits ends with finger wheels 6. A line spacing ratchet wheel 7 is connected to the platen and cooperates with other line spacing devices (not shown). Lugs 8 project forward from the rear bar 1 and are slotted to receive pairs of arms 9 and 10 which are pivotally mounted on shouldered screws 11 and 12. A rod 18 connecting the arms 9 carries sections 14 composing the main feed roller, and a similar rod 15 on the arms 10 carries the sections 16 of the secondary feed roller. The main and secondary feed rollers are arranged at the under side of the platen, the secondary roller forward of the main roller and between it and the printing point on the front face of the platen. Normally the main and secondary feed rollers are respectively maintained in contact with the platen or the paper thereon by springs 17 and 18. A rock shaft 19 hearing in the end bars 2 and 3 has lugs 20 which are adapted to engage pins 21 on the arms 9 and thus overcome the springs 17 and 18, swinging the arms 9 and 10 downward and releasing both feed rollers. The

be readily and conveniently actuated at a I release of the secondary feed roller is accomplished by extensions 9 of the arms 9, said extensions engaging with the arms 10 to actuate the latter. A paper deflector 22 is pivotally supported on the rock shaft 19 and partially surrounds the platen, the forward end portion of said deflector being normally pressed against the platen or the paper thereon by springs 23 on the arms 10, said springs relaxing when the feed rollers are released. The sections of the feed rollers protrude toward the platen through openings in the deflector The means for turning the rock shaft 19 comprises a c'ank arm 2% fined to the left end of the rock shaft and having a nose which norn'ially is maintained against a stop pin. 26 as shown in Fig. 2 by a spring 27 *oiled around the rock shaft. A releasing lever 28 is pivotally connected at 29 to the rank arm 24: and at 30 to a guide arm 31 which is pivoted at 32 to the end bar 3. The lever 28 has a finger piece which is adapted to contact with the arm 31 to limit forward movement of the lever 28. hen the finger piece is pulled forward sutliciently the parts 28 and 31, which are toggle elements, are straightened as shown in Fig. 4 and will hold the rock shaft 19 in abnormal position, locking the feed rollers in released position away from the platen.

The parts thus far described are common to the Monarch machine.

Leading edge or end stops are supported from arms or brackets 3 1 and 35 secured against the'outer side faces of the lugs 8 by the screws 11 and 12. The arm 3st extends straight downward and is curved forward at its lower end while the arm 35 extends downward and is laterally off-set outward toward the adjacent end bar 3 as indicated at 35, said arm 35 again extending down ward and then curving for ard below the offset as indicated at 35 By this construction the lower end portion 35 is considerably nearer the end bar 3 than is the upper or main portion 35 as clearly appears from Figs. 1 and 3. The lower ends of the arms 34; and have slots which receive shouldered pivot screws 36 which are held adjustably in place by nuts 37 and provide pivotal supports for a rock shaft 38, said rock shaft carrying one or more leading edge or stop members 39 arranged at suitable intervals along the rock shaft and secured thereto in any preferred manner as for example that shown and claimed in the application of C. J. Bond, Serial No. 482,678, filed March 11th, 1909, and which is herein illustrated. The stop members 39 comprise forwardly extending arms which incline slightly down ward from the rock shaft and terminate in upwardly bent ends 40 which serve as stops proper, said ends being pointed or beveled and being adapted to operate between the two feed rollers. A coiled draw spring 11 has its lower end secured to a hook 4-2 extending forward from the rock shaft 38, the upper end of said draw spring being hooked around the rock shaft 19. The draw spring tends constantly to turn the shaft 38 and draw the stops -10 toward the platen, from which said stops are normally separated as shown in Fig. 2. An upwardly extending finger 1 3 is suitably secured to the rock shaft 38 and normally cooperates with a headed pin or finger 41 1 which extends downward from the rock shaft 19 and is fast thereon. The spring 27 is stronger than the spring 1-1 and causes the finger 414: to push the cooperating finger 43 forward, thereby maintaii'iing the rock shaft 38 and the stops thereon in the normal or Fig. 2 position. .Vhen the finger piece 33 is pulled forward from the Fig. 2 to the Fig. 4 position it turns the shaft 19 and swings the finger l t rearward, thus releasing the finger and permitting the rock shaft 38 to be turned and the stops 40 to be moved toward the platen. At this time, however, the stops will move only a short distance, the full movement being prevented by restraining devices to which my invention is more especially directed. Said restraining devices include a stop member or finger 45 which, as best appears in Fig. 3, is secured to the left-hand end of the rock shaft 38 and curves forward and downward therefrom, being adapted to co-act with a movable stop or abutment in the form of a rod 416, said rod being slidably supported at its inner end in a hole in the part 35 and at its outer end in a hole formed at the lower end of a curved arm 47 which is secured by a screw 48 to the outer face of the end bar 3 behind the rock shaft 19, said arm 47 curving downward and forward from said screw 4:8. The outer end of the slide rod 46 is headed as indicated at L9, the head limiting inward longitudinal movement of said slide rod. The rod 46 carries a tubular housing 50 having a solid head or enlargement 51 which is screwed fast to said rod. A wire spring 52 is coiled around the rod 46 within the housing 50 and co-acts with the arm 47 and the bottom of the housing 50 normally to maintain the rod 46 in the position shown in Fig. 3. In this position the head 49 is in contact with the arm at? while the inner end of the rod &6 is in the path of the finger 4:5 and is adapted to interlock with said finger to arrest the same and hold the stops 40 away from the platen as shown in Fig. 4. This figure shows the parts after the operation of the release key 33 to release the feed rollers and bring the locking parts into co-action, it being understood that normally these locking parts are separated slightly although one is in the path of the other.

In order to release the finger 45 and permit the spring 41 to move the stops 40 to the platen after said finger has been arrested by the rod 46, I provide for snapping the rod 4:6 off the finger, sliding said rod 46 longitudinally outward in the direction of the arrow in Fig. 3 by an upright lever 53. The upper and lower ends of said lever are twisted so that their planes are fore and aft of the machine, the lower end being forked or cut out to engage loosely in a circumferential groove 51 in the head 51. The lever 53 is pivoted on a shouldered screw 54: which is supported on a block 55, said block being loosely mounted on the rock shaft 19 and confined between collars 56 fixed on said shaft, the construction being such that the rock shaft 19 may turn independently of the block 55. The upper arm of the lever 53 is shaped to provide a finger piece or key 57 which is operative from above the platen and is in proximity to the finger piece 33 (Fig. 2) so that both may be controlled together by the left hand of the operator. It will be apparent that when the key 57 is pressed inward toward the right, it will overcome the spring 52' and slide the rod L6 leftward in its bearings until it is withdrawn from the path of the finger 45, thus enabling the spring 4:1 to move the stops 40 to the platen, said stops passing through slots 58 in the paper deflector 22. After the finger 45 has passed upward beyond the lower edge of the end of the rod 46 the key 57 may be released for at this time the rod 46 will be prevented from returning to normal position by contact with the outer face of the finger 4:5. This will be understood from a consideration of Fig. 5 which shows the end stops and connected parts in operative position. At this stage a work sheet or bill sheet may be passed downward at the rear of the platen over the usual paper table (not shown) and the paper deflector 22 between the platen and the main feed roller 1 The advance of the sheet will be arrested by contact of its leading edge with the steps 40, which enable work sheets to be properly squared or alined and to be started forward each from the same position when the platen is turned after the feed rollers have been permitted to reengage.

The return of the feed rollers and retraction of the end stops 10 may be effected at one operation, said operation comprising two stages during the first of which the feed rollers will be brought back to operative position, the main feed roller engaging the work sheet and clamping it to the platen as shown in Fig. 6, wherein the work sheet is designated as a. This takes place while the end stops remain against the platen so that displacement of the work sheet is guarded against. This result is due to the fact that as the finger piece 33 is pushed rearward to unlock the feed rollers, said feed rollers will at once begin to move toward the platen and will reengage therewith or with the paper prior to the engagement of the finger l4: with the finger 4-3, as clearly appears in Fig. 6. After the feed rollers have been restored thearms 9 and pins 21 will be arrested so that as rearward movement of the finger piece continues the lugs 20 will separate from the pins 21. During this movement of separation the finger 44 engages the finger 43 and turns the rock shaft 38 backward, restoring the stop members 40 to normal position and moving the finger 4:5 downward past the slide rod 46 so that the slide rod may snap back to normal position under the action of the spring 52. During the return of the slide rod l6 the lever 53 will return with it to normal position and it will again require an operation of the finger piece or key 57 to enable the end stops to cotiperate anew with the platen.

It will be apparent that by the present construction a slight pressure or touch on the finger piece or key 57, during the operation of the release key 33, is all that is necessary in order to render the interlocking devices 45 and 4:6 ineffective and permit the leading edge or end stops to be brought into operation, this key 57 being in convenient juxtaposition to the key 33. It will further be apparent that the release key 33 may be operated to throw the feed rollers on and ofi at pleasure without affecting the paper stops t0; and that after the release key has been pulled forward and the feed rollers locked off, the stops 40 may be rendered effective by pressing the key 57 inward, thereby causing the slide rod 6 to snap off the finger as. It will also be seen that the mounting of the stops is simplified and improved as compared with my prior patented construction.

Various changes may be made without departing from the spirit and scope of my invention.
