Applicatioa "law 9, 3.5518. serial We. FQdloitk To @251 whom may concern Be it known that L citizen of the United States, residing at New York. WW, county of New York,

' .l orlr, have invented an improvement otlpacisg Attachments i Mar zines of which the following is a specie Mus invention has for its object to produce line spacing attachment which shall be supplemental to the regular line spacing device of a writing machine and be applied to new or old machines and which will. the operator to give to the lines any required uniform spacing, to space irregularly or to re-aline with perfect accuracy a sheet that has been removed.

It is of course Well understood that in Writing machines as ordinarily constructed the spacing of the lines is effected by the engagement of a pawl Wllil'hillle teeth of a ratchet wheel, three spacings being ordinarily provided which are known as single, double and triple spaces. My novel attachment is supplemental to this ordinary spacing device which may be used in'lieu of the attachment if preferred; Should it be required to space'irregularly, however as in filling in blanks, or should a spacing be required other than the three arbitrary spacin s rovidedby the spacing device of the machine or should it be desired to approximately fill a sheet of limited size with a certai 'i' number oi lines which would not correspond with either of the three arbitrary spacings provided by the machine it would be necessary to throw oil the spacing attachline by guesswork by and frequently to laten; that is, to draw the paper while olding the platen stationary. These diiiiculties are wholly overcome by the use of my novel spacing attachment in which the forward the platen is reflected by the action of an oscillatory collar and grip ping roller, the action of the collar hein adjustable so as to causethe roller to grig the platen at the required instant to produce the required line space by actuation of the usual spacing device'of the machine.

"With the above stated and other objects in view I have devised the novel attachinent which 1' will. now describe referring to the accompanying drawing forming a part of rotstion of the vplaten,

it should. be uhderstood that the invention is equally applicable to any of the various types and makes of ,writing machines in general use, certain parts only requiring; to be changed. and the principle being the same in all cases. I

20 denotes the platen and 21 spacing. ratchet wheel which is detacha'oiy secured to the right end thereof. The platen is ordinarily shouldered, ahd the spacing ratchet wheel forms with the shoulder a groove 22 which receives the oscillatory collar of my novel attachment, as will be more fully explained.

The ordinary spacing mechanism comprises essentially a line space lever 23, a hell crank. lever 24 and a spacing pawl 25 piw oted to the bell crank lever and engaging the spacing ratchet wheel. The spacing so muchfor rotating the P 52, lool ing Fig. 10 an ratchet wheel is normally engaged also by a roller 2? carried by a spring arm 27 which is rigidly secured to a fixed portion of the machine. This roller by engagement with the teeth of the ratchet wheel retains the platen in any position in which it may be placed. The roller is thrown out of engagement with the ratchet wheel by means of a lever 28. The various intermediate parts are not shown, and this mechanism is not illustrated or described in detail, as it forms no portion of the present invention and moreover differs in the various machines in general use.

My novel attachment comprises an oscillatory collar 29 mounted on the end of the platen, in the present i stance in groove 22, and having an enlargement provided with an elongated socket; 30 to receive a gripping roller 31. It will be noted that the lower portion of the socket is of less width than the diameter of the roller while the upper end or" the socket is of greater width than the diameter of the roller. A. lever 32 pivoted in the enlargement is provided in order to lift the roller out of. engagement with the platen when it is desired to move the platen backward, or to entirely release it, as indicatcd by the full line in Fig. 3, or to use the ordinary spacing mechanism. The dotted position of the roller in Fig. 3 is its normal position. When the collar is in the position shown in Fig. 3 with. the roller in the dotted position. torward movement of the collar c. upward movement from right, toward left) will cause the roller to wedgcbctwcen the wall of the recess and the platen and will carry the platen forward. The instant backward movement of the collar begins the collar will move downward away from the roller leaving the roller in the wider upper portion of the recess so that this backward or downward movement of the collar will. be free, leaving the platen in the position to which it has been carried by the it'orward movement. The oscillations of the collar are effected by means of an adjustable reciprocating link 33 which is pivoted to hell crank lever 24 and to an arm 34 extending from the oscillaposition of the roller tory collar. In the form illustrated in Figs.

the hnk C-UIHPHSQSW 3, 5 and 7 to 11, inclusive, a tubular member 35, a toothed slide 36 and a scroll wheel 37 provided with a finger piece 38. The scroll wheel is mounted to oscillate on a stud 39 and is retained in place. by a nut 40. The scroll 41 on the scroll wheel engages the teeth 42 on the slide and causes the slide to reciprocate within the tubular member to lengthen or shorten the link and cause more or less forward movement of the collar, and consequently a greater or less space between the lines printed by the machine. I have shown the tubular member as provided with a slot 43 at one end of which is a projection 4a. The

toothed slide is provided with a projection 4-5 which extends through the slot shown in Figs. 8 and 5. A scale 4-6 may be provided on opposite sides of the slot so graduated that the space between projections 4.4 and 4-5 will correctly indicate the space between lines printed by the machine. In liigs, 3 and 5, the link is shown as short-- cncd to the extreme of its movement, which would produce the longest space within the capacity of the attachn'ient. The space is shortened by lengthening the link, which is effected by rotation of the scroll wheel to move the toothed slide outward. a means for limiting the forward movement of the collar, I provide a lug 4t? thereon which at the extreme of the forward movement of the collar will engage a suitable stop, as the hub 48 carried by spring arm 27 on which roller 26 rotates.

In Fig. 6, l: have illustrated, the application of the invcntimi to a Remington writing machine. The oscillatory collar is provided with an arm t9, the spacing pawl 50 is pivoted to a reciprocating bar 51 and the adjust able link 52 is pivoted to the upper end of the spacing pawl and to arm 9. The space between lines printed by the machine is shortened by shortening the link and is lengthened by lengthening the link. The link in this form comprises a screw 58 pivoted to arm 49, a screw 54 pivoted to spacing pawl 50, a nut 55 engaging both screws and a lock nut 56 to retain the nut in. position after adjustment. A pin 59, projecting" from a. fixed portion of the machine, is provided for engagement by lug); 4? on the collar to limit the forward movement of the collar. The socket in the enlargement; of the collar is closed on opposite sides by cover plates operative position, as in fultline I when it is not desired to use the attachment, I provide one of the cover plates with a projection 553 which may be made by indenting the metal of the cover plat e. see Fig. 6,which shows the indentation on the outer side of the cover plate which forms the-projection on the inner side. In throwing the roller to the inoperative position, lever 32 is swung past the projection which acts to retain it in that position, and to rctainthe roller out of engagement with the platen.

The operation is as follows: If the attachment has been in use and it desired to use the ordinary spacing device of the machine, the ,gpipping roller is thrown out of engagement with the platen, as in Fig. 3, and the link is adjusted to its longest length and spacing pawl 25 is turned into operative position as in dotted lines in Fig. l. The condition of the machine is then precisely the same as it theattachment had not been applied. Suppose now that it is desired to use the attachment. Spacing pawl 25 is as clearly In order to lock ri i iin'r roller 31 out of, s l t. a s in big. 3.

thrown out of operative position as in full lines in Fig. and lever is moved to the clotted position in l ig. 3 which permits the gripping roller to drop down into operative position. The space hetween the lines printed by the machine determined by the length of the link which is adjusted to the requirements of use and will produce any reqiiiiredspacing within the capacity of the machine. if it is required to print a line and then. to space regnilarly from that line, ili'c paper is -ilaccd in position to print that line and then spacing by the attaclnneat will proceed from that line as already described.
