Yin: fmn'ze l of 3h ll'miertvoml it our tinge mil extending stwoss tno nmohii'ua and Supported near its opposite 6min by brackets Sprojccting from the frame. A front rail 4- is mounted at its ends in hi'ncltets 5. The usual carriage 6 is equipped nu th. hooks or ears 7 to engage the rear rail, and with wheel 8 running on the, front mil 4 '.no ears '7 are split, as at 9 to enable lfitEHi to pass the bttitfiit is 3 when planing in can ring? on or reumving it ,t't'tzn t tho no.

The shoe takes under a cross bar 17., and may be provided with a pin 18 traversing a groove 19 formed in the under face of the cross oar, to prevent thetzm'riage from jumping,

Heretofore, the cam has tei'l'ninated in a stop 20,lyii-ig in the path of the carriage, to prevent its rernoial from the machine; but to ofiect the removal and replacing of the trtn'iiiage with ease and despatch, I have arranged the stop to he shiftable into and out; of the path of the varriage, to which end, -nitl stop carried by a base 21 mounted on' the margin gago and guided in its n'mwinent. hack and forth by the teft-hnnd end of the min ll until a guide 22 on the gage, between wh ch the base is; fitted. A spring n01- nizilly urges the stop into the path of the vtit'i'izxgo, :in. abutment 2% against which the stop strikes, premnting overthrow of the stop, i i The ham: El of the stop may on slotted, as at 26, to ncmnnmodnto a check 7 preferably n thv twin; of a headed screw, the head, of l h ndies th'v use in pttavont IlpWfild inm'ei'nent of tho stnp reintzive to the gage, the check also opertiting to secure the stop to the margin gage. More than onetscrew Y may be employed, if-desired.

To enable the carriage to be disengaged i i l from the frafne, the stop is first moved backwhere itiis hel ward to its 'idlf Fig. 6, to enable the pin 18 to be removed 'passes said frame-supported from and inserted i'n said groove. Upon releasing the stop, the spring returns it to nor mal position (Figs. 1 and 5), and when the carriage is replaced, the shoe engages the outer beveled face 28 of .the' stop (-which projects above the abutment 24) to molv'e the step aside until the'shoe' has passed, after which the'stop resumes its effective position. The carriage is urged in letter spacing direction-by the u ual spring 29 having a strap 30 connecte to the carriage.- This -connection of the band to the carriagecan be automatically picked up a's the carriage is slid onto th frame, and released as thc'car-. riage is 'det, ched. The free end of 'the band carries a button 31 having a head 32 projccting above the stop to be caught by a cleft hook 'or fork 34 secured to the carriage, said button also having a head 33 projecting below the band to be similarly eng ed by a hook or fork 35 mounted on the fra e in the same vertical plan'e with. the carriagerslmported hook. Prior to placing the carriage on the frame; the button is held by its head 33. in the fork 35 on the frame. As the car.- riage is slid onto the ,frame, the carriagesupported hook 34 engages the upper head '82 of the button, (see Fig. 1), and thereafter slides the lower hea 33 out of the' frame-supported book 35-. The removal of the carriage operates to enter the lower head 33 of the button. in the frame-supported 'ho'ok 35, as the carriage-supported hook ook, the.carriage-supported hook thereafter releasing. itself from the upper head 32 of the button. The carria e is preferably removed and replaced frm the left side of the frame to facilitate the automatic release and enga ement of the carriage drive mechanism reIative to the carriage.

It w'ill be evident. that no dismantling of other parts of the machine is necessary, when removing the carriage from the frame or in replacing the same, and that its de- 't achment from and attachment to the frame is readily accomplished. without injuring or straining the parts.

Variations may be resorted to within the scope of the invention, and portions of the im rovements may be used without others.

aving !thl]S described my invention, I claim:

1. In 'a typewriting machine, the. combination with a frame and a detachable carriage movable back and forth thereon, of a stop on,the frame normally preventing the removal of the carriage from the frame, and shiftable'out of the enable its detachment from the frame without dismantling the frame, guides in which said stop is slidable outof the pat-h'of the carriage, and a In to hold struck by said carriage; said stop adjustable along the carriage. I

' 2. In a typewriting machine, the combination with a frame and a detachable carriage movable back and forth thereon, of a spring-y pressed stop on the frame normally pre'venting the removal of the carriage from the 'frame, and shiftable out of the pa h of the carriage to enable its detachment from the frame withoht dismantling the frame, guides to prevent displacement ofthe shiftable stop, and a lug against which the stop path of the carriage to the stop when normally rests; said stop adjustable along" the carriage.

3-. In a typewriting machine, the combination with a frame and a detachable carriage movable back andforth thereon, of a margin gage'on-the frame having a way thereon, a slide fitted in the way and bearing a stop normally lying in the path of movement of the carriage, the stop being shiftable out of the path of the'carriage to en-' able the detachment of the carriage from the frame without dismantling the frame.

4. In a typcwriting machine, the, combination with a franie and a detachable carriage movable hack and forth thereon, of a margin gage (-n the frame having a way thereon, a spring-pressed slide fitted in the Way and carrying a stop normally lying in the path of the carriage, the "stop being shiftablc olit of the path of the carriage to enable the detachment of the carriage fromthe machine without dismantling theframe,

and an abutment to arrest the stop and slide. In a typcwrltmg machine, the .comblnation with a frame, a detachable carriage movable back and forth thereon, a motor,.

'and a flat strap to-conncct the motor and carriage, of a button fixed to a flat (plate forming an extension of the strap, an flat cleft holders on both the frame and carriage closely adjacentsaid strap to catch and remove the button as one of the holders passes the otherin either direction.

6. In a typewriting machinc the combiback and forth thereon. of a shiftable stop normally lying in thepath of the carriage to arrest the latter atone end of a line, a support'on which the stop is mounted, guides to control the direction of movement of the stop, and abutments to confine the throw of the shiftable stop in either direction.
