so as to vary the stroke of the pawl D This collar D is connected by a link B with a collar. 13*, mounted upon the rod 13 and held:in place thereon by the collars 11 The pawl D has a spring-arm D extending, substantially, in a radial direction from its pivot and ap-' proximately at right angles to the direction of its motion at this point. The outer end of this spring-arm passes through a guide in one of the adjustable arms or supports A", carried upon the frame. These two arms are adj ustably connected by the bolt a, so thatthe elevation of the guide for the spring-arm D may be changed. The action of this spring-arm D is to throwthe upper end of the pawl toa ward. the ratchet-wheel E during the'down- .ward movement of the lever D-and' to throw thesame away from the wheel during the upward movement of said lever.

This is secured bya springDflwhich acts upon the lower end of the pawl D or the corresponding end of the lever D, upon which the same is mounted, to force the same upward.

This spring is madestrong enough to secure the forward feedingmovement. It is compressed or placed under tension by the down ward stroke of the keys and feeds the carriage by forcing'upward' the pawl D The pawl E" wi yield bycontact of the pivot of tive-ly connected to the-keys the ratchet \vheel'?,against its on or slo in surface.

notch in the outer end of the pawl-lever E.

This shaft also has. a, forwardly'extending arm J which is 'adapted to be engaged by a hook 1) upon the upper on of the link b This. linkb is connected'to o e of the levers B and therefore has a. reciprocating motion every time a key-is depressed. The upper end of this link passes through a hole in. a, plate L, which is mounted upon the upper surface of the type-writer frame and so as to slide across the same and in the direction of the travel of the carriage. Normally the hook I) will be held out of engagement with the arm J so that itsreciprocation will have no 7 effect thereon.

Mounted to slide in guides upon this plate .L is an adjustable plate L, which has an upwardly-projecting pin L This plate has a within which is a clamping'bolt L screwing into the plate L. This permits co'nsiderable-adjustment ofthe plate and consequent variation in the point from which the return movement is given. The carriage frame has a pinor arm a, projecting downward so as to engage the pin L? when the care riage is within two letters of. the end of its travel. On depressing a key (or the spacer) the forward movement of the carriage will then move theplate 'L so as to bring the hook b into engagement with the arm J; This hook is held toward the arm J a bye. small spring b and when the parts arein this pohook will be touching the side of the arm J Upon depressing one be raised 'to a point where the spring b will cause the hook to engage over the end of the arm J upon the shaft J. The hand being will be depressed, carrying-with it the armJ? upon the shaft J and elevating the arms J. and J thus releasing the pawls E'and F from their respective wheels and permitting point of starting again. The plate L has an upwardly-projectinglug ,'L ,'upon.which is pivoted a lever N. The

lower end of this lever projects through a slot oin the frame and by the side of or through again the hooklb will the carriage-return spring to act upon the carriage and return the same to its a slot of the plate L. -,The upper end of the ,lever is in the tached to the'carriage-frame A". The view shown in Fig. machine. 1 As the carriage travels toward the endof its stroke, or to the right as shown in Fig. 6, the arm a will engage the upper end path of travel of an arm a, at-

6 is taken from the rear of the of the lever N and pass over the same without affecting the position of the plate L; The plate L'is, however, moved to the right on the return of the carriage by the engagement of the arm a with the pin L Upon the return of the carriage the arm a will engage the upper end of the lever N, and its lower end will engage one end of the slot at, with the result that the plate L is moved to the left or back to its normal position. The position of .the plate L shown in Fig. 6 is the outermost position or that which causes the upper end of the link b to engage the arm J J to be returnedto its normal position. The pawls E and F may ,at any time be released from their respective wheels, permitting the carriage to return to its startingpoint by means of the rods or links m, which are attached to the rear end of the levers M, which at their forward ends are provided with keys M. I have shown one of these levers upon each side of the machine. One'of these may be omitted, if desired. The upper ends of the rods or bars m pass through holes in the frame and engage the under surface of the arms J 4 and J which are attached to the shaft J. The depression of the keys Mwill os- ,cillate the shaft J, so as to disengage the.

pawls E and F, thus permitting the carriage tobe returned under the influence of the guard H and spring H.

Then the shaft J is oscillated so as to release these pa wls, thearm J 4 is engaged bya notch in the upper end of a. link or harm, which is pivoted at m to the frame. This b;& is pressed toward thecenter of the ma- G'Jgine by a spring 012?. When the arm .1 is

:raised', it will he engaged by the notch in the frame, so that it may have aslight horizontal I A spring 1 upon one end pulls 'link or harm and held in its raised position until the bar m has been moved to the left.

. A rod I is journaled in the arms A of the movement. the rod toward that end. At the other end it is provided with ratchet-teeth I for bold ing the adjustable stop I, which is mounted on the rod 1, arranged above the rod I. The position of the stop I will regulate the position of the beginning of the line. Inits center at I this bar I is given a sidebend or 01f set in order to clear the wheel F. The end of this bar which is atthe left in Big. 2 is respective ratchet-wheels while the arm J is.

raised. As the arm J cannot be released until the carriage has completed'its return,

- these pawls E and F. cannotenga'ge their It sets the] plate L in position again and allows the shaft ratchet-wheels .until .the stroke of the carriage is completed.

Beneath the rack-bar C is pivoted a lever C upon a lug A attached to the frame. This lever at its outer end is provided with a pivoted arm or dog G which is controlled by a spring 0', attached to the lever 0 The other end of the lever is connected bya link G with a lever O, which-extends to the front of the machine and is provided with a key 0 by which it may be operated. When the key C is depressed, the end of the leverC carrying the dog 0 is raised, so that the upper end of the dog will engage the lower surface of the rack-bar ,C; 'The upper end of this dog is' -adapted to enter the space between the teeth of the-rack-bar. The rack-bar, as previously described, is pivoted to the frame so that it may rise slightly. The dog will thus raise the bar until it clears the pinion C. The spring H will then return the carriage as far as the dog 0 will permit. This is so proportioned that the dog will oscillate a distance 'sufiicient to permit the carriage 'to return one space. As the key 0 is permitted to rise the bar 0 will drop into engagement with the pinion O. This operation may be repeated as many times as desired, the carriage returning one space for each depression of the key, thus permit:

ting the carriage-(to, 'be fed backward accnrately and quickly,so that a letter which has been incorrectly struck or skippedmay be inserted, with a certainty that the insertion is in the proper place. In case it is desired to make the impression very strong, the letter may be struck more than once,with a certainty that the impression'will be upon exactly the same spot as the. first one.

The shaft J is provided with depending arms K. The levers'B are also provided with lugs b. .The normal position of the arm Kis one in which its lower end is slightly in front of the lug b and so that the two will not engage when the levers Bare operated. When the shaft J is oscillated either by the depression of-the keys M or in any of the methods provided, the arms K being attached to said shaft J and depending from it are swung back so that their lower ends are immediately over the lugs b of the levers B. This results in locking the lovers B, so that they cannot be depressed, and consequently,owing to the-com nection between the said levers Band the .key levers, all the key-levers of the machine will be locked,so that they cannot be operated. 'lhe arms K- will be thrown to th normal positions-+that is, in frontof the lugs b of the levers B-so that'the said levers'will be released as soon as the carriage has returned to its starting-point; This prevents striking any of the keysuntil the carriage isin proper'position.v I'have shown thearms K as-upon each side of the machine.- -'One'of these may be omitted, if desired.

The ribbon-feed consists of a spring-pawl G mounted upon the'lever B and engaging wheel is connected by a pair of bevel-gears G with the shaft G',=which carries the ribbonspool;

In Fig. 4 the carriage is shown elevated,- so that the line being written upon is visible. Upon the paper-clamping bars at each end of the roller A are formed marks V, which serve as guides or indicator-marks'for indi eating where the line of writing will appear-' that is to say, will show the-line upon which the writing will appear on blank paper. This location may be indicate", if desired,-by projecting points instead of by marks. The latter, however, are thoughtto be more readily 1 provided and are capable of insertion withfront of the machine.

I have provided an arm A, attached to one end of the carriage, by which it may bemoved by hand when desired. This arm is provided with a lug a", resting upon the guidebar 07. This of the-carri hand.

I have provided an automatic device for feeding-the paper, which is shown in Figs. 1 and 3. The roller A, about which-the paper.

Mounted in journals upon the carria e and extending from front to rear is a bar P, having an arm P depending in This bar has. an arm P fixed thereon and an arm P mounted loosely thereon. The latter is provided with a pin p, projecting to one side, soas to be. engaged by the arm P The arm P is held downby a spring P", attached to the carriage-ft frame. The out-er end of-the arm I carries abar P to the lower end of which is pivoted 5o enables the roller a pawl P 1 A pin P is attached to the frame and projects in front of the teeth on the ratchet-wheel, so as to engage the pawl P and hold the same normally out of engage- .ment with the ratchet-whee1.
