Application filed November 26, 1906. Serial No. 345,107.

It; all 107mm it may concern:

Be it known that. I, (11.10 B. Yaw, citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Writing -Machines, of which the-followin is a specification.

My invention re ates to typewriting ma chines and more particularly to means for atlording control of the paper or work sheet in a manner and for purposes which will hereinafter appear.

It has been customary heretofore to use circular letters in which the body of each letter was printed in imitation of typewriting or was reproduced by the min'ieograph process, the date, name and address of the addressee being afterward filled in on the typewriting machine and reliance being had on the skill and judgment of the operator to properly space the date, name and address in accordance with the spacing employed in the body ofthe letter and to position each of the lines to be Written on the typewriting machine in its proper place on the sheet.

One of the main objects of my present invention is to provide means for facilitating the accomplislnnent of work of the character specified above with mechanical accuracy, said means beingsimplc in construction and operationi'eflicient in use, and their employ mentgreatly increasing the output of each machine to which they are applied.

To the above and other ends which will hereinafter appear, my invention consists of the features of construction,arrangements of parts and combinations of devices to be described in the following specification and set forth in the appended claims. In the drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a'fragmcntary right-hand end elevation with the finger.-

eel sectioned away, showingthe upper portion of a typewrit'ing machine with the devices of my invention aiplied thereto. Fig. 2 is a fragmentary top plan view of the same. Fig. 3 is an enlarged fragmentary sectional view taken centrally through the platen, and showing various features of the construction forming the subject-matter of Fig. 4 is a the platen and platen frame with the devices of my invention. carried thereby. Fig. 5 is an enlarged dctai] vertical sectional view showing the controlling devices and platen with parts shown in end elevation, the section being taken on the line u/ of Fig. 2 and looking Fig. 6 is a like view of the same showing some of the parts in other positions. Fig. 7 is a side elevation, partly .in section, of the parts shown in Fig. 10, Fig. '7 being a view corresponding to a section taken on the line 'c-v of Fig. 11 and looking in the direction of the arrow at said line, although the positions of the parts are somewhat different in the two-views. Fig. 8 is a fragmentary top plan view of the right-hand end of the platen with parts shown in Figs. 5,13 and 7 applied thereto. Fig. 9 is a fragmentary sectional view taken on the line 'w-w of Fig. 11 and looking in the direction of the arrow at said line. Fig. 10 is a transverse sectional view of the controlling devices shown in Fig. 7, the section being taken on two views of parts of the mechanism to be hereinafter described. Fig. 17 is an enlarged detail transverse sectional view taken on the line z--2 of Fig. 4 and looking in the direction of the arrow at said line. Fig. 18 is an enlarged detail front elevation of the com bined paper guide and indicator. Fig. 1!) shows a work sheet addressed on the machine with the aid of my invention.

My invent-ion, which is applicable to typewriting' machines generally, 1S more mrticularly adapted to a so-callcd blind or bottom strike machine and in the present instance {have shown the invention applied .to a No. (S'ltemington machine.

The specific construction of the stop carrying members and that of the pawl and ratchet mechanism'hy which said members are operatively connected to .the platen, are not. claimed herein except insofar as they enter into combination Willi other features,

filcd by me of even date herewith; said com,- panion application bearing the Serial No. 345,106.

but are claimed in a companion application of the machine carrying upwardly extending lugs 2 onwhich a guide rod 3 is supported. A carriage truck 4 of the usual construction carries rollers 5 which bear upon the guide rod 3. A platen frame is pivoted at 6 to the usual links 7 which, in turn, are pivoted to the truck. Said platen frame comprises a front cross bar 8, end bars 9, and a rear cross bar 10 to which the links 7 are pivoted. A platen 11 is journaled in bearin in the end bars 9 of the platen frame. roller 12 is carried by the front cross bar of the platen frame and bears upon a shift -rail lid-carried by upright arms 14 which may be shifted in the usual manner to effect a backward or forward shift of the platen to change the case position thereof. The usual main paper feed rollers (not shown) are emplo ed. The usual paper tin-3 gers and Iflalfgllltt? by combined paper feeding fingers and indicating devices such as those shown in Figs. 4, 17,and 18. Each of these devices-comprises a plate or paper finger 15 which is bent to. conform to the curve of the platen and is aper-tured at 16 to enable a marginal feed roller 17 to extend therethrough and to bear agaiiist the face of the platen or the paper thereon. The member 15 extends rearwardly, under the platen, beyond the point where the usual platen scale is situated, and it extends upwardly in front of he la-ten, to a point which is preferably higher than the front cross-bar 8 of the platen frame as shown in Fig. 4. The up per end of the member 15 is broadened and the edge 18 thereof forms a line 'indicating gage with which a line for writing 'on the work sheet' is adapted to registei' as will hereinafter more clearly appear. Theplate 15 at its upper end is off-set inwardly as indicated at 19 so as to form the broad indicating gage 18, which latter is provided with scale or indicating marks 20 spaced apart accordin to carria e and platen scales or to the letter space eed of the carriage; that is to say, the spacing between the index marks 20 corresponds to letter spacing produced on themachine. Each of the marginal feed rollers 17 is pivoted at 21 in a bifurcated iortion, formed by two arms 22, of a depending hanger 23 pivoted at its upperend as at 24-betwecn arms 25 of -an angle bracket 26. This bracket is provided with an inclined face 27 adapted to engage the front cross-bar 8 of the platen 'CI'OSS- bar.

frame, as shown in Fig. 17, whereas another part of the bracket rests upon the top of the A clamping plate 28 bears against the bracket and is perforated for the free passage of a' screw 29 provided with a knurled head 30. A coiled spring 31 sur-.

rounds the screw and bears at one end against the'knurled head and at its opposite end against the clamping plate 28 in order to feed rollers are replacedmaintain the bracket in the position to which it may be adjusted along the front cross-bar of the platen frame. An angular plate 32 bears at 33 against the bracket so as to receive a slight pivotal movement thereon. The horizontally disposed arm of this angular plate is perforated for the free passa e of a screw 34 which is received in a threat ed opening in the bracket. A nut 35 is received on the screw and bears against the upper end ofa coiled spring 36, the lower end of said spring bearing against the angular plate and tending to force the substantially vertically disposed arm thereof toward the platen. .The lower end of this vertically disposed arm of the angular plateis pivoted at 37 to the member .15 intermediate the ends of the latter. The construction is such that the pressure which is exerted by the spring 36 on'the angular plate 32 and which is transmitted to the member 15 intermediate of the ends thereof causes the member 15 to bear with substantially even pressure at all points thereof which make contact with the platen, and causes the upper end of the gage 18 to bear snugly against the Jlaten'. hanger 23 is provi ed at its upper end with two faces 38 and 39 which cooperate with a spring-pressed plunger 40 iii the usual manner to either maintain the mar- 'nal feed roller against the platen as shown in Fig. 17 or to petain it in the inop'erative position away from the platen when the hanger is moved so that-the face 38 contacts with the plunger. pap'erfingers,- the marginal feed rollers, gages 18, etc, at both ends of the platen is the same except that letter spacing indices 20 need only be'provided on one of the gages. The purpose of these gages 18 and the indices 20 will be'presently described. A line spacing wheel 41 is operatively connected to the platen in a manner to be hereinafter described, and the usual, line spacing pawl '42 and spring-pressed roller detent 43 cooperates with the line spacing ratchet wheel to effect step-by-step line spacing movements thereof. The line spacing pawl 42 co-acts with a device 44 pivoted at 45 to a bracket 46 which projects upwardly from the right-hand end of the platen frame. The device 44 is rovided with three faces 47, 48 and 49 which cooperate in the usual manner with the line spacing, pawl to vdetermine whether the platen shall be turned one, two or three teeth of the line spaciii ratchet wheel at each actuation of the ban lever 50 by which the pawl is actuated. This mechanismis or may be of the'same character as that emplo ed in the No. 6 Remin on machine and urther description tliereo is deemed unnecessary. I have shown in the present instance a line s acing wheel having thirty-one teeth; wiich The feed roll The construction of the ing 4D platen head is wheel is adapted to be connected with and ing secured to the core by wood screws 54 which pass through openings 55 in the platen head and pass into the core. The line 8 acing wheel 41 is in the nature of a ring, t e inner bearing surface 56 of which is seated on a reduced hub-like portion 57 of the platen head so that the line spacing wheel and platen are free under certain conditions to turn relatively to each other to afford a rotation of the platen independently of the line spacing wheel. A securing plate 58 is rigidly connected to the outer end of the hub-like portion 57 by headed screws 59 which extend through openings in the securing plate and are received in threaded openings 6Qin the platen head. The platen head is provided with oppositely disposed channels .61 in which clamping or gripping devices 62 are seated. Each of theseclamp devices comprises a member whiehis bifurcated at one end to form clamping jaws 63, a bearing portion 64 and a lever arm 65 which extends longitudinally of the platen. The bearing portion 64 of each clutching device bears against the wall 66 of the channel in which it is received, whereas each set of clamping jaws cooperate with and 'are adapted to engage the line spacing wheel. The provided with an outwardly extending nipple 67 which is received in a bearing opening in the right-hand side bar of the platen frame as shown in Fig. 3. This nipple is hollow and its bore 68 is a continuous one which extends through the platen head for the reception of a spindle 69 provided at its outer end with a finger wheel 70. Extending laterall -from the bore 68 are slots 71 formed intl ie platen head, thus formin s line grooves on each side of the bore w icli grooves receive a spline 72 to connect. the spindle and the platen head to rotate together and to afford endwise movement of the spindle independently of the platen head.

A contractile spring 73 surrounds the spindle within the core of the platen and is secured at one end to the platen headersindicated at 74, the opposite end ofsaid spring t-cing secured as indi-f cated at- 75, to the spindle. The inner end of the spindle carries a device-'76 which cooperates with inclined faces 77 on the arms (if) of the gripping devices. This constructronis such spread apart that the spring 73 tends to the inner ends of the arms 65,

' ring 78.

of the thus ell'cctiing a clamping engagement between the gri ping devices (32 and the line spacing wheel to connect the line spacing wheel with the platen. An inward movement. of the finger wheel will cause the device 76 to be moved to the left, thus releasing the pressure of the spring 73 on the. gripping devices and enabling the platen to turn independently of the line spacing wheel which at this time is held by tl'iespringpressed detent roller 43. A plate or ring 78, shown in detail in Fig. 12, is secured to the core of the platen by the screws 54 which unite the platen head to the platen, said screws passing through openings 79 in the This ring is provided with a slot 80 which is adapted to register under certain conditions, to be hereinafter described, with a cut-out, 81 in the surface or sheath of the platen ,at the right-hand end thereof, as shown'in Figs. 2 and 11. A circular flange 82 is formed on the platen head and a ring or stop carrier 83, shown in detail in Fig. 15, is'situated between the line spacing wheel and the late 43 and bears on the periphery ange 82. This ring 83 has a circumfe'rential recess or groove 84 therein for the. reception of a pivot 85 of a. combined locking device and stop 86 shown in detail in Fig. 14. A lateral or transverse. recess 87 is provided in the ring 83 to enable the stop 86 to move therein and to be turned on its pivot 85. A so-called stop carrying device or ring 88 (shown in detail in Fig. 16) which is angular in cross section as shown in Figs. 3, 10 and 11. surrounds the ring 83. An inwardly extending flange 89 on the stop carrying member 88 receives a bearing on the circular flange 82 of the platen head and -the inner face of the flange 89 bears against the outer face or side of the ring 83. This stop carrying member 88 and the member 83 are situated between the line spacing wheel and the plate or ring 78 as shown in Fig. 3, and are prevented by said parts from moving longitudinally of the platen though they are loosely mounted on the platen head.

The stop carrying member 88 has a series of slots 90 in one edge thereof to form a circular rack, sixteen of such slots being employed greater or less number may be provided.

An index numeral is provided adjacent to each slot, the muncrals ieginnlngat 0 and ending at l5 and being circularly arranged as shown in Fig. 16. The edge of the stop carrier in which the slots 90 are provided bears against the plate 78-50 that when any one or the slots 90 in which the stop 86 may be seated is brought into regis ter with the slot; 80 (see Figs. 9 and 11), said stop may. be turned on its pivot 85 to carry the stop out of the slot 90 and into the slot 80 and into the cut-out portion 81 of the platen as shown in Fig. 11. This in the present. instance though a seated in any one of the slots '90 in the stop movement is effective to clear the stop 86 from the member 88 and to connect it'and the ring 83 with the platen. In this manner the stop 86 may be connected either with' the stop carrier 88 or with the platen 11 and a relative movement between the stop carrier and platen may be effected in order to brin any of the slots 90 opposite the slot so'tl at an adjustment of'the stop 86 may be effected and so that the sto may be carrier 88. If, for instance, the stop 86 be seated in a slot QO'adjacent to the index numeral 4, so as to lock the members 86, 83 and 88 together, and it is desired to seat the ,s'to in the slot adjacent to the index numeral 8, the clutch which connects the platen and line spacing wheel is released and then the platen is turned independently of the line spacing wheel, the latter being, held by its spring roller detent 43, until the slot 80 is opposite the slot 90 in which the stop 86 is seated and then the stop is turned on its pivot 85 to the position shown in Fi 11. The platen clutch being released the p aten with the stop 86 and the ring 83 to which it.

is pivoted niay'be turned independently of the member 88 and the line spacing'wheel to which the member 88 is operatively connected-as will hereinafter more clearly appear. 'VVhen the stop 86 is oppositethe slot 90 adjacent to the index numeral 8' the stop maybe turned on its pivot 85 into said slot, thus disconnecting the stop from the platen and connecting the stop-and'the mem-. bers'83 and 88 togetheras shown in Figs. 3, 7 and 10. Thestop carrier 88 also 'carries a stop 91 which is in the nature of an angular piece or bracket rigidly secured to the periphery'of the stop carrier. by a screw 92 as shown in F 6. A lug 93also pro-- "jects from the periphery of the stop carrier 88 and apawlfitis'pivbted at 95 to said lug. The pawl is 'provided with an inwardly projecting'pin -96. against which the free end of a flat -spr1ng 97 bears, said spring being formed as an extension of the angular stop 91. The pawl 94 is situated at one side of the stop carrier 88 as shown in .Figs. 5, 6,"

and 8, and the nose of the pawl coeperates with the teeth of the line spacing wheel, the spring 97 tending to force the pawl into engagement with said teeth. The disposition of the teeth of the line spacing wheel and 'pawl'9 4 and theconstruction and arrange 'ment of the parts are such that when the laten clutch' is in engagement so that the ne 5 acin wheel and platen turn together, a bee war rotation of-the direction of the arrow in Fig. 5, efi'ected through either .finger wheel, will cause the - members 83, 88 and 86 to rotate with the platen by reason of the positive engagement ofthe pawl 94 with the line spacing wheel. When a. forward rotation of the 'with the platen and the laten in the platen is effected these members will turn will be arrested and the platen will be al owed to rotate independently thereof as will presently appear. A stop member 98 is secured to the platen frame by screws 99, and extends into V the path of the stops 8G and 91 for cotiperation therewith. a

From the foregoing description it will be understood that the platen and line spacing wheel being clutched'together a backward rotation thereof, effected byeither finger wheel, 'will bring the stop 86 against the fixed stop 98 to positively arrest the platen, because the teeth of the line spacing wheel so I during this movement of the platen engage the pawl and force the stop carriers around with the platen. When the platen is turned in'an opposite direction-the stops 8G and 91 and theirstop carriers will be turned with the platen by reason ofthe friction between the parts and the spring pressure exerted by the pawl 94 on the teeth of'the line spacing wheel. This rotation of the parts together will continue until -the stop 91 reaches the fixed stop 98 when the stops 91 and 86 and their stop carriers will be arrested and-the platen may continue "to rotate independently thereof, the pawl 94 at this time slipping over the teeth of the line spacing wheel. As soon as the laten starts to turn back in an o posite irection the stops 86 and 91 will immediately be taken up by the pawl and ratchet mechanism and the platen will be arrested when the stop 86 contacts with the fixed stop 98.

The spacing of the teeth of the line spacing wheel corres ends to the character of spacing employed in the body of the circular letters to be addressed on the machine. In the present instance I have shown a ratchet wheel with thirty-one teeth. The edge 18 of the indicator is situated at such a distance from the printing line, this edge being at the forward side of the platen, that in a blind or understrike machine theoperator may readily observe when the line written on the work sheet registers with said indicator at a regular line space osition of the platen without swin ing the platen'back. In constructing the mec anism, one manner of determining the location of the indicating edge, is as follows :-Place a circular letter of the character to be em loyed in the machine with the first line of the previously written or printed letter (indicated at b in Fig. 19) at the tinting line. Then turn the platen forwardly .a tooth of the line spacin wheel at a time until this first line b in the body of the work sheet appears at the front of the platen and at any point where it can be 18 of the indicator is made to register with the bottom of the letters of the line in question on the work sheet. \Vhile the platen readily observed by the operator. The edge-- was being turned forwardly a tooth space distance at a time in the manner descrlbed, the number of tooth spaces required to bring should, therefore, be situated in this particular construction just ten tooth space distances from the first slot 90 in the member 88. A suitable number of slots 90 may be provided from this point around the member, sixteen being employed in the present iuslance and twelve being as man as is ordinarily required, as will present y appear. These slots 90 are spaced in accordance with the spacing of the teeth of the line spacing ratchet wheel.

In addressing letters, the bodies of which have been previously printed, written or produced by the mimeograph process, it may be assumed that the spacing between lines a and I) (Fig. 19) in the body of each letter corresponds to the distance between two teeth of the line spacing ratchet wheel. The operator sets the device 44 of the line-spacing mechanism so that the face/l8 on said device is presented for coiiperation with the tail of the line spacing pawl in order to provide a movement equivalent to two teeth of the ratchet wheel at each actuation of the hand lever- 50 so that the spacing in the heading may correspond to that employed in the body. of the letter. The operator may then release the platen clutch and adjust the stop 86 in the manner hereinbefore described so that said stop will be 'seated in the slot 90 beneath the index numeral 8 The reason for this is that it is necessary to locate the first or date line f just eight spaces from the first line Z'J'in the body of the letter.. This will oi ing the name line e two spaces from the uat'c line f; it will bring the address line two spaces from the name line 6; it will bring the salutation line a two spaces from the address line and the Salutation two line spaces from the first line b in the body of the letter. In short it will provide for writin the lines f, e, (Z and a two spaces apart wit the line two spaces from the line I), such spacing corresponding to the spacing between the lines in the body of the letter. Thus, after the sto 86 is set at 8 in the manner described t e platen is 'ven a. backward, rotation until itis arreste b the contact of the stop 86 with the fixe stop 98. A .previo"usly written-or printed letter of the character :SL'tCll,-f0t' instance, as that shown in Fig. 19, except that the lines f, e, d and c If o]; appearthereon, is introduced into the machine and the platen is mined forwardly until the line b register== witn the indicator 18. The platen is then. turned back until it enable t e operator to set the device up is arrested bythe contact of the stop 86 with the fixed stop 98. This manipulation of the letter sheet brin s it in position to write the date line f. A ter this line is writ, ten the line s acin handle '50.is actuated once, thereby ringing the sheet in position to receive the name line 6. written the handle is again actuated, thereby bringing the work sheet in position where the address line (1 may be written thereon. Another actuation of the handle .positions the work sheet to receive the line -0 after which the sheet may be removed, a new sheet introduced and the operation repeated.

It will be seen that by my invention let- After this is ters or the like may be rapidly addressed on p a blind machine with mechanical accuracy without the necessity of raising-the platenor examining the work at any time; that the spacing in the addresses of the different letters will be uniform and the spacing of each address will conform to the spacing in the body of the previously written or printed letter in which the address is inserted, and that the different addresses will be at a uniform distance from the bodies of the letters.

If the lines in the body of the letter are situated a single line space distance apart the ordinary line spacing device will be. S for single 'spacing,-the stop 86 will be set at 4 on the carrier and the addressing of the letter sheets will be carried out in the manner hereinbefore described and the spacing-between the lines f, e, d, 0, b and a will corres nd to a: single tooth space dis tance of, t e line s acing wheel. If; three spaces are employe between the lines in the bod of the letter then the line spacing mec anism is set for triple spacing and the lines will appear three 3 aces apart.

Most typewriting mac ines are provided with line s acing mechanism capable of single, doublia or triple spacing or of spareing one,two or three teeth of the line spacing ratchet wheel at-a time and ordinarily four lines are required for an address. This being the case the stop 86 requires an adjustment equivalent to four, e' htor twelve teeth of the line spacing wh four for single spacing, eight for double spacing and twelve for tm le spacing. Although a twelve space adiustment is the maximum that is ordinarily required I, have provided in the resent instance sixteen slots 90 to to a maximum of a five line address with the lines situated three spaces apart.

It will be understood that all that is necessa-ry to properly position each sheet is to effect a forward movement of the platen until the first line in the body of the letter is in register' with the indicator 18,. and then turn the platen back until it is arrested. by the stop 86 contacting with the stop 98,

I and the operator may proceed to address writing nearest the top of the work sheet will appear a predetermined number of line the letter.

The purpose of the letter space indices 20 is to bring the sheet into roper position so that the letter spacing in the address will correspond with that in the body of the letter. The operator in bringing a sheet forward so that the line b registers with the gage 18 should see at the same time that: an of the letters in the line registers with the marks 20.

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