Specification of hatter-s Patent.

Application filed February-26, 1910. Serial No. 546,188.

To all whom it may concern:

Be it known that I. HERBERT H. STEELE, citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new vand useful Improvements in Type- W riting lllachines, of which the following is a 'spe :ilication.

My invention relates especially to paper feeding mechanism for typewriting machines and its general object -is to provide improved devices of the class specified.

Tothe above and other ends my invention consists in the features of construction, cornhinations devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In typcwri ative all of the paper feeding render inop V cooperate with the platen by devices whic 1 meanseontrolled by a key or hand lever so that a single operation entirely releases the paper from the control of the mechanism.

paper feeding This, of course, is highly desirable since it enables paper to he introduced, adjusted and removed with facility; but it also possesses certain disadvantages. *or example, in some forms of billing work it is common to reproduce the items of the bills or invoices on an underlying record sheet which remains in the machine as the different bills are removed and replaced by other bills, said record sheet being manipulated so as to receive in condensed form the records of a considerable number-of bills. If the first entry at the top of-e. record sheethappens to be that of a short bill, one, say, in which there are but one or two lines, then after the entry has been written and the record sheet ted backward for-condensing purposes. the release hey is operated and the leading: edge stop devices positioned for cooperation with the next bill sheet to be entered. in the suppositious case, however, the record sheet will have been fed backward so far that it will have passed out of control of the paper fingers and the pressure rolls-usually carried by said fingers, so that there will be nothing to hold said record sheet in position; duningthe adjustment of the second bill sheet said record sheet is liable to become displaced, thus iinpairing the alinenient of subsequent record entries. My present improvements obviate this dis advantage by providing in addition to a release lever or key which operates to release all the paper feeding devices, a second release lever or key which operates to release certain only of said paper feeding devices so as to enable the record sheet to be held against the platen under all conditions that may arise during the Work.

My invention will be more particularly described in connection with the accompanying drawin s which illustrate one form of said invention applied to a Monarch front-strike typewriting machine, although it is to be understood that said invention may be adapted to other styles of writing machines.

In said drawings, Figure 1 is a fragmentary plan view of the platen and platen carrier of a Monarch typewriting machine embodying my invention, parts being omitted and parts broken away. Fig. 53 is a vertical transverse sectional view of said platen and platen carrier. Figs. 3 and 4 are operating views corresponding to Fig. 2 but showing the parts in dilierent relations. Fig. 5 is a (liag'an'nnatic view showing the paper feeding and controlling devices set for the introduction of a bill sheet.

- In the drawings, the platen carrier which comprises a rear bar 1 and end bars 2 and 3 carriesa platen 4i mounted on an axle 5 and. provided at its ends with finger wheels 6. A line spacing ratchet wheel I coiu'iec'led to the platen and cooperates with other line spacing devices (not shown). lugs S project forward from the rear her l and are slotted to receive pairs of arms 9 and 10 which are pivoted at ll and 12. A. red or shaft 18 connecting the arms 5) carries sections 14 composing the main feed roller, and a similar rod or shaft 15 on the arms 10 carries the sections 16 of the secondary feed roller. v

The main and secondary feed rollers are arranged at the under side of the platen, the secondary feed roller forward oi the loo and the printing line.

prise pins 37 fixed to and projecting from.

printing point on the front faceof the platen. Normally the main and secondary feed rollers are maintained in contact with the platen or the paper thereon by springs 17 and 18, which operate respectively against the arms 9 and 10. Forward of the feed roller 16 is a platen scale or plate 19 which is provided near its ends with brackets 20 which are pivoted 011 pins 21 carried by arms 22 secured by screws :23 to lugs 24 ,on the rear bar 1. Leaf springs 25 tend constantly to press the upper edge of said scale toward the platen. Said scale is connected by diagonally disposed links 26 to pins 52? extending laterally from enlargements 9 in which the lower ends of the arms 9 terminate.

Extending dmvnward transversely of the printing line so that their lower ends overlie the scale plate l9,-"are spring pressed guide fingers 28 pivoted at 25) on supporting arms 30 which also carry spring-pressed rolls 31 cooperating with the platen through openings in the fi1'1gers 28. The arms 30' curve over the top of the platen and at their rear ends terminate in hubs 32 which are slidably but non-rotatably supported on a paper finger rod so that each paper finger contrivance comprising a support 30, pressure roll 31 and guide finger 28 may be adjusted lengthwise of the platen. Paper is adapted to be fed into the machine over a paper table 34-. and deflector or apron 35, the latter being formed with openings through which the feed roller sections protrude and being pressed toward the platen by leaf springs 36 secured to the arms 10.

As the machinehas been heretofore constructed, key controlled releasing mechanism is provided which when actuated throws off from coiiperation' with the platen, or releases, as it is called, the main and secondary feed rollers, the apron-35, the scale plate 19 and the guide fingers 28 all to gether. In the present instance I provide devices controlled by a key which is operative to effect the same results, but I further adapt said devices to the control of an other key whereby only'the main feed roller 14 is released without affecting the other paper feeding and controlling elements in advance of or between said main feed roller Said devices comthe arms 9, which pins are adapted to be acted on by other pins or lugs 38 fast on a rock shaft 39 journaled on the platen car' rier. The construction as thus far described is not novel, the rock shaft 39 and the lugs 38 and pins 37 being well known, the present embodiment of the invention residing in novel means for variably controlling the rock shaft.

Referring to Fig. 2 which shows the parts i in normal position, it will be observed that the enlargements 9 are separated sufficiently from the arms 10 to enable the arms 9 to be swung downward on their pivots far enough to carry the main feed roller away from the platen before the enlargements 9 contact with the arms 10. It is through the operation ofthe enlargements!) on said arms 10 that the latter are swung down to release the secondary feed roller and other paper controlling devices. Consequently it will be understood that if the turning of the rock shaft 39 ceases prior to the co-action of the enlargements 9 with the arms 10 the main feed roller will be released without affecting the secondary feed roller and paper apron and also without affecting the paper plate and paper guide fingers, these two last named elements being controlled by the links 26 which operate only during the last stage of movement of the enlargements 9 when they co-act with the arms 10. The means for turning the rock shaft 39v only far enough to release the main feed roller Without affecting the other paper feeding devices comprise a crank arm 4:0 which fits over the left-hand end of the rock shaft 39 outside the end bar 2 and is secured to said rock shaft by a screw 41 (Figs. 1 and 4c). Said left-hand end of the rock shaft is squared and the hole in the crank arm is c0rrespondingly squared so that the relationship between the crank arm and shaft is fixed. The crank arm -10 is provided with an upwardly extending finger 42 which normally contacts with a stop pin 43 on the end bar 2. The crank arm 40 is provided near its forward end with a headed pin 44 which cooperates with an arcuate slot 45 formed at the lower cm. of one member 46 of a toggle connection, said member being pivotally connected at 47 with the other member 48 of said connection, the member or arm 48 hav- 1 ing a pivot 49 fast on the end bar 2. Above the pivot 47 the member 46 is bent inward angularly to provide a finger piece or key 50, this key portion cooperatin with the rear edge of the arm 48 to limit tl ie forward movement of the tog le connection. The normal position of said toggle connection is illustrated by dotted lines in Fig. 4. When the key 50 is pulled forward the toggle is straightened and the upper end ofthe slot 45 engaging with the pin 44 will press the crank arm 40 downward, turning the rock shaft 39 and causin the lugs or pins 38, acting on the pins 3, to swing the arms 9 downward, moving the main feed roller 14 to the released position shown in Fig. 4. The top end of the slot 45 and the pin 44 are so related'that the forward movement of the finger piece 50 is arrested by the rear aeoaar an edge or" the arm -18 before the enlargements 9 have operatively engaged with the arms 10. Uonsequently the auxiliary feed roll it) will remain in operative position as shown in Fig. 4. Moreover, the wire links 26 form loose connections between the scale plate ill and the arms 9, so that the lost motion between the arms 9 and the scale plate will not entirely be taken up during the movement o'f'the arms 9 from the normal to the Fig. 4t )osition and consequently the scale plate i9 and the guide fingers 28 will not hcdisturbed but will ren'iain in operative position. When the finger piece 50 is pushed rearward the feed roller 1+1, crank arm 40 and rock shaft d5) will be restored to normal position by the springs 17. The pin and slot connection 414-, +15 provides a lost motion connection between the meniber 4:6 and the crank arm 4d), the purpose of which is to permit the crank arm to swing down ward such that when the rock shaft 39 is turned from its'right-haml end the crank arm ah) may swing 't'rcely dmvnward, carrying the pin ll, said pin traversing the slot without affecting the member 46, the entire toggle connection remaining undisturbcd.

The rock shaft 39 is adapted to be turned from its right-hand end for the purpose of releasing all the paper feeding devices, by means which comprise a crank arm 51 having a hub 52 which surrounds the rock shaft 39 inside the end bar 3, said hub 52 being fixed to the rock shaft by a set screw 53 (Figs. 1, 2 and 3). The c ank arm 51 extends normally forward and slightly upwardly as shown in vFig. 2 and is provided with a headed pin 54 which' coiiperates with an arcuate slot 55 formed at the lower end or" a toggle member 56, said member being pivotally connected at with a second toggle member 58 pivoted at 5.) (in the reduced end of rod 33 having a fixed pivot 59. The

' upper end of the member 56 is formed to provide a key or finger piece. which is bent inward so.that it may co-act with the rear edge of the mcmberefiS to limit the forward mo\-'o1n- .-nt of the toggle connection. The toggle connection comprising the members 58 and 56. is similar in most respects to the toggle connection at the lcft-hand side of the machine previously described, but the distance from the pivotal center 57 to the top of the slot l'ifi'is greater than the corresponding distance from the pivotal center 47 to the top of the slot Consequently the toggle connection 58, 56 will, when straightened, operate through the crank arm 51 to turn the rock shaft 39 forward to a greater oxtcnt than willitlna left-hand oggle connection. The rcsult'ls that when the tinkcy 60 is pulled forward from the normal to the Fig. 3 position it will operate not only to throw oft the main feed roller i l but will cause the enlargements 9 to co-act with the arms 10 to release the secondary feed roller 16 while concurrently the links so will operate to swing the scale plate 19 away from the platen, said scale plate in turn acting against the lower ends of the guide fingers 28 to release the same. The position of he pants at this time is shown in Fig. 3. will be apparent that the operation of the release key 60 is similar in cttect to the operation of release keys hitherto provided. it will further be understood that when the right-hand releasing devices comprising the toggle members 56 and 58 are in normal position, the operation of the release key'50 will swing the crank arm 5h downward and cause the in 54 to traverse the slot 55 with: out affecting the member 56.

in operation, when the record sheet, bill sheet and intermediate carbon inlay are to be introduced into the machine, the key 60 is pulled forward, thus releasing all the paper feedin devices and aliording a clear passageway rom the rear or iiitroductory side of the platen past the printing point at the front thereof so that the three sheet-s may be expeditiously pushed around and adjusted in place for receiving the first line of writin After such adjustment the finger piece (30 is pushed rearward and the paper feeding devices permitted to return to normal position under the control of the v restoring springs provided for the purpose.

Assuming that the bill comprises but a single:

entry composed of but mie'linc'of writing, the operator at'thc end of this line of writing removes the bill and turns the platen backward until it reaches the point where the record sheet will be pl'OlJtJl y positioned to cooperate with the next, bill sheet when it is introduced at. the back of the machine. This point, as is well understood, commonly determined by a ppropriatc indicating or stop devices comprised in the billing mechanism which is not disclosed herein. As soon as said mini is reached the operator throws fOIWzll't the key 50, releasing the main feed roller but not atlecting the secondary teed roller is so that the record sheet and the arbon inlay will be hold in .place by the secondary feed roller, the baclc feeding movcmentnot being of sufficient extent to draw the record shoot. and carbon inlay backward past the roller l6 but only, say, to the location shown in Fig. 5 where the record sheet and carbon inlay are illustrated and respectively designated by the reference characters a and 2'). Said Fig. 5 also illustrates in operative position a leading edge stop (31, which stop may be of any appropriate construction, as in the lt'lonarc -the paper apron 2-15.

machine, and is adapted to cooperate with the platen between the main and secondary feed rollers through suitable openings in After the completed. bill sheet has been withdrawn a second bill sheet designated as d in Fig. 5 may be introduced over the paper tabli and paper apron and positioned with its leading edge against the stop ('31.

stored to action and the leading edge stop mechanism is operated to withdraw the stop (31 from abnormal position. Thereafter the platen is turned to bring the work sheets into position for printing and the work may be proceeded with as he tore.

7 After the billsheet. (.Z has been I properly arranged, the feed roller it is ret It will be observed that by my present invention duplex means are provided for variably controlling the teed roller ll. the

duplex means in the present instance coniprising two sets of toggle devices controlled by separate keys, one key at one end ol' the platen and the other key at the opposite end of the platen. By said duplex means the .teed roller may be locked away from the platen in two ditlerent inoperative positions. lVhen moving to one of these inoperative positions said feed roller does not affect the'seeondarv feed roller and other paper controlling devices, while when said teed roller is moving to the other of said iuin'ierative positions the release of the seeondarv feed roller and other paper controL ling devices is effected during a single oporation; that is to say, couein'reutly. The main and secondary feed rollers are parallel and are arranged at difi'erent points circumferentially of the platen, the secondary t ed roller being ar 'anged between the main teed roller and the printing line which in the present instance is at the trout tare of the platen. The feed roller It is releasable by a movable member or rock shaft which is provided with releasing devices such as the lugs or pins 33, this memberor rock shat't being movable, or in the present instance rotatable, ditl'erent extents by key-controlled devices which comprise crank arms lixed to the rock shaft and toggle members such as it; and :36 having loose or pin and slot connections with said crank arms so as to enable the l'tlt'li shat't. to be turned by operating cithcr ltcy without att'ectingthe other key.

\"arious changes may be made without departing from the spirit and scope of my invention.
