citizen of the United State of N cw York, have invented certain Specification of Letters Patent.

Application filed April 12, 1909. Serial No. 439,263.

To all whom it may concern:

Be it known that I, EDWIN E. BAnNnY,

States, and resident of Syracuse, in the county of Onondaga and 1 new and useful Improvements in Type- Writlng Machines, of which the following is a specification.

My invention relates to paper feeding mechanism for ty 'iewriting machines and especially to leading edge stop devices for such machines.

' The main object of the invention is to provide improved devices oft-he class specified.

To the above and other ends, the invention consists in the features of construction, combinations of devices and arr'angements of parts hereinafter described and particularly pointed out in the claims. My invention is designed as an improve ment over the prior constructions shown in the applications of C. J. Bond, Sr. No. 482,678, filed-March 11th, 1909, and Jacob I Felbel, Sr. No. 486,210, filed March 27th, I 1909. Like the Bond construction the presen-t construction provides a leading edge stop device which is constantly spring pressed toward the platen but which is normally held away from the platen in a 1 certain position by a stronger spring con- I trolled by devices connected with the release key of the machine. In Bond when the release hey is operated to swing the feed rollers away from the platen the leading.

mitted to draw stored to normal position.

lllomlrch typewriti-ng inachi-ne but said instruction, however, the leading edge stops edge stop spring is at the same time perthe leading edge stops into operative position. In the present conmove only a short distance toward the platen from normal position when the release key. alone is operated, said stops being then ar-' rest-ed byan obstruction which can-only be removed to permit further movement of the stops to the platen by the operation of a key separate from the release key and operative independently thereof. In this latter respect the present construction resembles that disclosed in the Felbel application. The present construction further resembles Felbel in that at asingle operation the feed rollers and the leading edge stops may be re- 5 I have shown my invention applied to a.

. my feed rollers areres vention may be adapted to other styles of writing machines.

In the accompanying drawings, Figure l is a fragmentary bottom plan view of the platen carrier and planten of' a- Monarch typewriting machine embodying my invention. Fig. 2 isza fragmentary bottom plan View showing details of construction of the shaft for the leading edge stops and its mounting parts being shown in section. Fig. 3 1s a vertical sectional vie taken on a plane represented by the dotted line 50-00 in Fig. 1 and looking in the direction of the arrow at said line, Fig. 3 however showing the platen carrier turned over in its normal position. Figs. 4 and 5 are views corresponding to Fig. 3 but showing some of the.

parts in different relations and. omitting other In the drawings, 1 designates the back bar of the platen carrier or carriage, which carrier further comprises side or end bars 2 and 3, said back bar' being grooved at its top and bottom to anti-friction calls (not shown). A platen 4: is mounted on an axle 5 which bears in the end bars and is provided at its ends with finger wheels 6. A line spacing ratchet wheel 7 at one end of the platen is adapted to codperate with other line spacing devices (not shown) to afford line space turning movements of the platen. Lugs 8 projectforward from the back bar 1 and are slotted to receive pairs of otally mounted on shouldered screws 11 and 12, said screws bridging the slots in said h gs. A red 13,connecting the arms 9 carrles the sections 14 of the main feed roller and a similar rod 15 on the arms 10 carries the sections 16 of the secondary feed roller. These feed rollers are spaced apart circum- Patented Sept. 28, 1909..

The sections of the main.

and secondary feed rollers protrude through openings in the deflector 22 to contact with the platen or the paper thereon. When the rock shaft 19' is turned to release the feed rollers the pressure of the springs 23 relaxes. The parts thus far described are usual in the Monarch machine.

The release rock shaft 19 may be turned or operated by any desired means, that shown in the drawings being disclosed and claimed in my prior application Sr. No.

403,531, filed November23rd, 1907. Said means comprise a crank arm 24 suitably secured to the end of the rock shaft 19 outside the end bar 3. Normally a nose 25 on said crank arm is maintained against a stop pin 26 extending laterally outward from the end bar 3 by a spring 27 coiled around the opposite end of the rock shaft 19, and having one end secured thereto and the other end to the bar 2. The normal positions of the rock shaft, feedrollers and paper def flector are shown in Fig. 3. lever28 is pivotally connected at 29 tothe crank arm 2% and at 30 to a guide arm 31 which is pivoted on the usual paper finger rod 32. The free end of the lever 28 terminates in a finger piece which is bent and which is adapted 'to contact with the rear edge of the arm 31 to limit the forward movement ofthe-lever 28. The parts 28 and 31 are toggle elements which normally are disposed at an angle to each other but when the finger piece 33 is pulled forward sufficiently said toggle elements are straightened as shown in Fig. 4 so that the crank arm24 and the rock shaft 19, which have been turned forward by the finger piece 33, will be maintained in the abnormal positions,.(l*ig. 4.), thus locking the main and secondary feed rollers in released position away from the platen.

The leading edge or end stops and the devices which support and control them will now be described. Arms or brackets 34 and 35 are secured against the outer side faces of the lugs 8 by the screws 11' and 12. The arm 34 extends straight downward and is curved forward at its lower end while the arm 35 extends downward and is then lat- A releasing erally off-set outward toward the adjacent end bar 3, said arm 35 again extending downward and then curving forward below the off-set. By this construction the lower end portion of the arm 35 is considerably nearer the end bar 3 than is the upper portion of said arm 35, as willbe clearly understood from Figs. 1 and 2. At-their lower end portions the arms 34 and 35 are formed with openings or slots which receive shouldered pivot screws 36 and 37 (Figs. 1 and 2), the shanks of both screws being smooth and cylindrical. The screw 36 is held in a fixed relationship with the arm 34 by a nut 38. The shank of said screw extends a considerable distance inward. The pivot screw 37 is somewhat shorter than the screw 38 and is held in a fixed relationshipwith the' arm 35' by a member 39 which is in the form of a curved arm and combines the functions ing which engages the threaded portion of the screw 37 and operates to clamp said screws against the arm 35. From the screw 37 the arm 39 curves upward and forward and then downward and forward, as will be best understood from F ig's." 3 to 5, and is bent inward at right angles at its forward end to provide a stop or abutment 10 for purposes presently to be described. .The screws 36 and 37 provide su ports for a rock shaft 41, said rock shaft eing formed with depressions or seats 42 and 43 which receive the shanks of said screws, the latter serving as bearings on which said rock shaft maybe given rotary movements. That end of the rock shaft 41 which is adjacent to the nut,38 terminates normally some distance short of the inner face of said nut, being maintained in this normal position by a wire spring 44 which is coiled around the screw 36 and is confined between the-end of the rock shaft and the nut as shown in Figs. 1 and 2. Said spring, it will be understood, normally maintains the bottom of the depression 43 in contact with the end of the screw 37, said screw serving as a stop to .the left as viewed in Figs. '1 and 2,or

toward the right when viewed from the:

front of the machine. The means of accomplishing this endwise movement and the purpose thereof will presently be described.

The rock shaft 41 supports one or more leading edge or end stop members of suitable. construction. Foultsuch members are 4 shown in the present case each being num-,,'L

o bered 45. They are arranged at suitable intervals lengthwise of the rock shaft 41 and approved manner.

secured thereto in any in thepresent instance are in These members the form of arms which extend forward downward from the rock shaft 19; The 1 the abutment by the spring 47 as shown in jerfd of the arm positions.

l'arm 51 and the, endwise and slighty downward from the rock shaft 11 and terminate in upwardly bent ends 46 which serve as the stops proper, said ends or stops being somewhat pointed at their extremities. A coiled draw spring 47 has its lower end secured to a pin. 48 fixedto and extending for-ward from the rock shaft 41. Said draw spring extends upward and its upper end is hooked around the 'rock shaft 19. The draw spring tends constantly to turn the shaft &1 and draw the leading edge stops 46 toward the platen, from which said stops are; normally separated as shown in Fig. 3. A finger i9 is suitably secured to the rock shaft 41 and extend. upward and l forward therefrom, Cooperative with the upper end portion of said finger is a headed pin or finger 50 which is fixed to and extends spring 27 is stronger than the spring 47 and f the pressure of said spring 27 being comi municated to the finger 50 causes said finger to push the cooperating finger 49 forward, thereby maintaining the rock shaft 41 and the stops thereon in the normal of Fig. 3. When the finger piece 33 is pulled f01-, ward from the Fig. 3 to the Fig. 4- position it turns the shaft 19 and swings the finger or pin 50 rearward, thus releasing the finger 4-9 from the control of said pin 50 and permitting the rock shaft 41 to be turned and. the stops 46 to bemoved toward the platen.

At this time, however, the stops will 'move only ashortdistance, the full movement be ing prevented by a stop member or arm 51 which is suitably fixed to the left-hand end of the rock shaft 4-1 as shown in Fig. 2 and which is formed with a cut-away, the edge 59 whereof swings against the abutment or stopdO, thus limiting the initial upward. movement of the stops 46.

In order to complete the upward move ment of. the stops and enable them to contact with the platen I provide means for moving the stop arm 51 laterally inward away from the abutment 40. Since the stop arm 51 is fixed on the rock shaft 4-1 said rock shaft must also participate in this lat eral movementof said arm. The means for accomplishing the lateral movement of-the movement of the push rod which n hole in thelower or bracket 35 which is ex tended forward for the purpose; The outer rock shaft 4-1 comprise a at its nner end hears in end of said push rod is. slidably mounted on .an arm or bracket 54 which is suitably se cured to the endbar 3 from. @utside the end presided with and dep'endstherel bar 3 the rod 53 is 44 and moving the a push hutton-or key 55 (Fig. b

1). A wire spring'56 is coiled push rod and confined between the supporting arm and the key 55. This spring tends constantly to force the rod 53 outward. A collar 57 secured to the rod 53 by a screw courts with the inner face of the arm 54 to limit the outward movement of the rod and maintain it in in Fig. 1. Normally the inner end of the rod 53 is separated from the outer face of the stop arm 51, but from Figs. 3 to 5 it will be apparent that the inner end of the push rod 53 is always opposite some portion of the face of the stop arm Hence when ever the rod 53 is pushed in it will engage the stop arm 51.

Suppose that the releasing arm 28 has been pulled forward and locked, thereby throwing off and locking the main and secondary feed rollers, and permitting the edge 52 of the stop arm 51. to be drawn against- Fig. 4. 'lhcreupon, in order to bring the stops 46 against the platen the key is pushed in, overcoming the spring 56 and causing the inner end of the rod 53 to press against the arm 51. This pressure forces the arm 51 inward, overcoming the spring rock shaft- 41 endwise. As soon as the arm 51 has been pushed past the abutment 40 the draw spring 47 will operate-to move the stopsi-(i upward against the platen, at. the same time swinging the arm-51 upward, said arm slidingover the end of the abutment. 40. As soon as, the arm 51 has been pushed inward past the abutment 40 the keyoo may be released, permitting the spring 56 to restore it and the push rod 53 to normal position. The rock shaft 41 and the parts it carries will however continue to be held in abnormal position by the abutment 40. During this last or final stage of the upward movement of the stops 46 they will pass through openings or slot ways 59 in the paper deflector 22. From Fig. 1 it will beseentlmt normally the stops 46 are not con1pletely in register with the slots 59.

However, the slight endwise movement com-- around the the normal position shown unmicated to the rock shaft 41 will bodily move the stop members 45 sidewise until at the momentof release the pletely in register with 59 and will pass'freely upward therethrough to contact with the platen. At this stage the parts will be in the positions shown in Figv 5 so that 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 14. the advance of the sheet being arrested by the contact of its leading edge with the stops 46. As is well understood this enables work sheets to e properly squared or alined and to be stops 46 are com-- the face of the abutment 40.

leading edge or end 'siderahle. extent and until t'l' started forward each from the same position when the platen is turned after the return or reengagement of the feed rollers.

The return of the feed rollers and the retraction of the end stops 46 may be and preferably are accomplished at one operation. This operation, however, preferably and in the present instance comprises 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. During this first sta e the stops 46 remain against the platen, tiereby preventing any disarrangement of the work sheet. This result is accomplished by so arranging and proportioning the parts that as the finger 33 is pushed rearward to unlock the feedrollers, said, feed rollers will at once begin to move toward the platen and will retingage with the platen or the paper thereon prior to the engagement of the finger 50 with the finger t9. After the feed rollers have been returned to the platen, the arms 9 and the pins 21 will be arrested, so that as thereafterrearward movement of the finger piece 33, continues the lugs 20 will separate from the ends of the pins 21. It is during this movementof separation of the lugs 20 and pins 21 that the finger 50 engages-the finger 49 and turns the rock shaft 41, restoring the stop members 45 to normal position and moving the arm 51 downward out of engagement with As soon as the arm 51 is lowered past theabutment 40 the spring 44 will operate to restorethe rock shaft 4:1 endwise to its initial position, moving the arm 51 sidewise so that it will again require an operation of the push key 55 to enable the end stops tocoiiperate with the platen.-

My construction provides means for accurately positioning and clamping work sheets on their introduction into the machine and said constrm-tion may be advantageously used in condensed record work, bill-andcharge work and other styles of commercial typewriting or hillin v In the present case a spring-pressed push-button or key is provided upon which a slight touch or depres-, sion only is necessary in order to cause the stops to be, brought to operative position against the platen. This mode of operation of my construction gives it advantages over prior constructions wherein it has been necessary to move the stop key or actuate the tin er piece to a, con- "mnent of contact of the sto )s with the platen. It will beobserved that y the present construction theflpush button or key is not atl'ccted until after the prior operation of the finger piece 33 to release and lock oli' the feed rolls. This will be obvious from a, consideration of Fig. '1 wherein it will he observed that the end platen by the finger 50 and that the push key 55 has no efiect upon this finger. lt is only after the finger 50 has been moved back as in Fig. 4 and the arm 51 has been drawn up against the abutment 40 that the operation of the key 55 is effective, said key then operating to snap one of the interlocking parts ofi the other, thus operatively disconnecting said parts, although they may still be in contact at certain points. It will be seen therefore that normally there are two means or sets of devices which restrain the end stops l6 from operative position and against theirspring 47 that neither of these restraining means 1s in itself alone operative to release the 'end stops but that both restraining means must be operated to permit of such release; that one of these restraining means comprising the finger 50 is removed or rendered ineffective automatically by the means for releasing and locking away the feed roller or rollers; that the other or main restraining means comprises parts adapted to interlock, that is, the arm 51 and the co operating abutment r0; that this main restraining means may be rendered inefiective or its parts separated by means comprising a spring pressed key or finger piece; that the operation of this key is independent of the lockin away of the feed rollers, so that i-. is possible to release and lock off the feed rollers for adjustment of the paper o for other purposes without bringing the end stops into action, these end stops being controlled at will after such locking ofi of the teed rollers; and that luring the return of the parts to normal position after the locking off of the feed roller 01 rollers and the bringing into action oi the end stops, there are two stages, during he first of which the feed roller or rollers roturn into cooper ttlOll with the platen while the end stops remain in operation, and during the second of which the end stops are moved away from the platen to normal position while the feed roller or. rollers remain quiescent.

Various changes maybe made without departing from the spirit and scope of my invention. 7
