Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed May 14. 3908. Serial No. 432,775.

To all whom it may concern:

Be it known that l, HENRY T. FODDRILL, a citizen of the United States, residing in Atlanta. in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Type-Writing Machines. of which thefollowing is a specification.

This invention relates to the paper feeding and controlling devices of typewriting machines, and particularly to tally strips and means for writing and feeding the same in conjunction with bills or main sheets.

The principal object of the invention is to provide simplified, inexpensive, compact and easily manipulablc means for preserving upon a tally stri a record of the amounts of items to be bil ed.

In the preferred manner of carrying out the present improvements, the bill or main sheet is introduced into the machine, and occupies a position between the tally strip and the platen. The items are written by the types upon the bill, and the amounts are written upon the tally strip, the latter being coated with carbon on the side next to the platen or the bill, so that carbon copy of the amount is made upon the bill. Thus by means of only a single pair of spools to carry the tally strip, provision is made whereby both the strip and the bill may show the written amounts, and liability of error is avoided in transcribing the amount onto the telly strip after it has been written upon the bill. A further advantage of course is the saving of time in avoiding the necessity of writing each amount twice,

namely, once upon the bill and once upon the tally strip.-

The line spacing of the tally strip is preferably effected by the same lever that line spaces the usual platen; and for this purpose, the strip winding spool is provided with a ratchet wheel; and an extra pawl, for operating said wheel, is mounted upon the 'slide which carries the nsual platen-rotating pawl. A movement of said slide, ettecte by the usual line spacing lever, therefore rotates the platen and the strip-winding spool simultaneously. The strip-winding spool may however be silenced at will to permit line-feeding of the platen while the strip remains stationary. The stripwinding spool is also revoluble independently of the platen be introduced to carry the strip around the platen while the latter remains stationary.

The strip-winding spool is located back of the platen, and draws the strip in a. direction'opposite to the direction of the linespacing movement of the platen. The strip is carried up back of the usual paper shelf to the winding spool, so that the bills may readilv be introduced between the paper shelf land the platen in the usual manner.

The right hand border of the bill underlies the tally strip. 1 also provide a tubular guide for the tally strip around the under side of the platen and back to the windingspool, to avoid injury to the strip, and also to avoid liability of smudging the bills from the carbon or lamp black on the tally strip.

Other-features and advantages will hereinaftcr appear.

In the accompanying drawings, Figure 1 is a plan of a platen frame of an Underwood front strike writing machine with my improvements applied thereto. Fig. 2 is an elevation thereof. Fig. 3 is a perspective view illustrating the manner in which the tally strip is looped around the platen, Fig.

4 is an elevation of the left hand end of the platen frame andmechanisrn seen at Figs. 1 and 2. Fig. 5 is a section taken transversely through the platen and longitudinally through the strip guiding tube. Fig.

(l is a perspective part-sectional view illustrating the mechanism or line-spacing of the tally strip. Fig. 7 is an elevation and Fig. 8 is a plan of a levehoperated slide,

carrying pawls for line-spacing both the 6, which extends from end to end ot the platen frame behind the platen and inclines downwardly and forwardly to the lower side of-theplaten. A bill or main sheet .7 may in the usual mannerand fed forwardly around the platen by the usual pressure rolls 8, the latter provided with the usual release key 9. Y

A tally strip 10 is carried down from a delivery spool 11, and looped around thethe front side ofl95 platen, and led upwardly and baekwardly to a Winding spool 12. The strip is coated with carbon Fig. 3, only on the side which is next to the platen. It is led from the platen behind the paper shelf 6, so that the hill 7 may readily be introduced between the shelf and the platen, with the spool 12 back of the sheet 7. The latter in emerging from the machinepasses rearwardly over the platen and beneath the spool 11, the spool \being carried upon an upstanding arm l3, which is ofl'set, as at 14, from the spool to afford a passage for the outgoing sheet 7. hen the arm 13 is out of use, it may be turned to the dotted line position, at Fig. 4, to carry the spool 11 out of the way back of the paper shelf. The arm is pivoted upon a rod 15 provided in the platen frame, and is pressed by a spring 16 against a detent 17 fixed upon the platen frame and fitting in a recess 18 in the arm to hold it yieldingly in working position seen in full lines,,Fig. 4. The tally strip 10 passes down from the delivery spool around the-front side of the platen, and thence back through a guide in the form of a Wide flat tube 19, which curves down around the front side of the platen, and backwardly beneath the same, and is directed thence up toward the winding-spool 12. The upper side 19 of the tube forms an apron over which the strip travels. Said tube is preferably secured to the rear side of the paper shelf, as seen best at Fig. 5.

The strip-winding mechanism includes, in addition to the spool 12, a shaft 20 upon which the spool is mounted, a ratchet wheel 21 mounted upon said shaft, and a pawl 22 to turn the ratchet wheel. The pawl is normally out of engagement with the ratchet wheel, so that the spool may be turned at any time by means of a hand wheel 23 fixed upon the same end of the shaft as the spool 12;

. said shaft extending the entire length of the platen frame, and jorn'naled .in the ends thereof, and carrying the ratchet wheel 21 upon the end opposite from the hand wheel 23. 1

The pawl 22 is carried upon the same slide 24 (or an extension 25 thereof) that carries the usual pawl 26 to drive the usual platen ratchet wheel 27; so that when the usual handle 28 is moved to the left. Fig. 1, not only the platen 2, but also the strip-winding spool 12 is rotated; said lever forcing said slide rearwardly, and the pawls ,22 and 26 simultaneously engaging and operating the ratchet wheels 21, 27, Fig. 4. It will be seen that said slide 24 is guided in the usual manner in the end 4 of the platen frame for a backward and forward movement, and is provided with the usual returning spring 29. Upon the return movement of the slide effected by said spring, the pawl 26' is withdrawn from the ratchet wheel 27, by reason ..of engagement of a nose 30 on said pawl,

with a trip 3.1 formed upon a plate 32, the

latter maybe turned in either direction by hand wheels 36; 37 independently of the strip-winding spool 12. Hence the bill and thestrip may, independently of each other,

be fed in either direction. The usual spring detent 38, releasable by a cam lever 39, is provided for the platen, and any suitable spring detent 40 for the ratchet wheel 21.

In operation, the stationary spool 11, with the strip wound thereon, is placed upon the arm 13, and the strip is passed downwardly, backwardy and upwardly through the tubular guide 19, and connected to the winding spool- 12. Then the bill 7 is introduced with its ri ht hand border between the tally strip and file platen; the tube 19 being separated from the platen sufficiently to form a passage 41, Fig. 5, for the bill. The items are then written by the types, line by line, in the usual/manner, the amounts being written once only, that is, upon the tally strip, and the carbon copies of said amounts being made upon the face of the bill.

Whenit is not desired to line-space the strip by the lever 28, the trip 35 is moved backwardly, Fig. 6, sufficiently to hold the nose 34 elevated, so that the pawl 22 never engages the wheel 21 during the strokes of the slide 24, 25, thereby silencing the ratchet .wheel 21 and spool 12 during the line feeding of the platen. It will be seen that the trip 35 is carried upon the rear end of a slide 42 mounted upon shoulder screws 43, 44 and having'a finger piece 45 at the front of the platen frame. A detent spring 46, mounted upon the slide 42, engages suitable notches, as 47 in the platen frame end 4', to detain the slide in either position to which it is shifted by the handle 45. Thus, the severalitems and their amounts may be written line by line upon the bill while the strip remains unfed. and then the fingerpiece 45 may be thrown forwardly before the lever 28 is operated to feed the bill up for writing the footing. so that the strip may be fed a single line: and only the foot ing may be written upon the strip. and its carbon counterpart caused to appear upon the bill.

Variations may .be resorted to within the t will also be seen that the stripscope of the invention, and portions of the I frame having a paper shelf in rear of the. platen, of a winding spool mounted back of ea eei frame having a paper shelf in rear of the platen, of awinding' spool mounted back of a 1y strip extending .therethe paper shelf, a t from back of the paper shelf forwardly heneath and around the platen and back over the same, and a spool'ahove the platen from which thestrip is paid 05.
