ASSIGNOR TO ROYAL TYPEWRITER COM- 4A CORPORATION NEW YORK TYPEWRITIN G MACHINE Application filed October 11, 1927. Serial No. 225,480.
This invention relates to means-by which the usual margin stop may be released from the stop bar and held by a part of the frame of the machine while the carriage and stop bar are moved independently of the said stop. This enables the stop to be adjusted to any desired position since if the stop is to be set at any particular letter space position of the carriage, it is only necessary to operate the releasing mechanism, move the carriage to the desired letter space position and release said mechanism, allowing the'stop to again engage with the stop bar.
Either of the ordinary margin stops may be adjusted readily and quickly to any desired letter space position. The key which releases the margin stops from the stop bar `is also adapted to roperate the usual lever which releases the carriage from the escapement mechanism and permits it to be moved in either direction to the desired point'.
Further features of the invention will be apparent from the following detailed description and will be set forth in the appended claims.

release lever This invention is applicable to a standard form of typewriting machines but for convenience has been illustrated in connection with the standard Royal typewriter.
There is illustrated a platen A mounted in Side frames B of the carriage, which frames are connected by a tie rod C. An escapement wheel D is mounted in thc main frame E and has rigid therewith a pinion F which meshes with a rack G carried by a bail l'l h aving arms K pivotally supported on the side frames of the carriage. A bent lug L on the carriage release lever M underlies one of the arms K so that by operation of thil the bail is lifted and the rack G disengaged from the pinion F to permit movement of the carriage in either direction. There is also shown in Figure l the usual tabulating stop bar N.
The margin stop bar l is supported at its ends in the side frames B of the carriage and has a central longitudinal slot in which slides a relea bar 2. rThe stop bar carries pins 3 which pass through inclined slots -L in the release bar so that an endwise movement of the release bar from the position shown in Figure 7 will cause the bar to ride upwardly until it projects beyond the edge of the stop bar as shownin Figure 8. This endwise movement is brought about by the following mechanism.
The finger lever 5 is pivoted to one side of the carriage by the same screw 6 which holds one end of the tie rod C in position. This lever has a bent over arm 7 connected by'a link 8 to one arm 9 of a bell crank lever pivotally supported on the carriage and having its other arm l0 engaging a cut-out ll in one end of the release bar 2. A spring 12 which has one end fast to a fixed support on the carriage and the other end passing through a hole 13 in the release bar returns the lever to normal position when pressure,
is removed from the finger lever 5. The lever 5 also has a pin 14 projecting outwardly and overlying the carriage release lever M so that when the lever 5 is operated, not only will the release bar 2 be moved to its operative position, but the carriage will be released from its escapement mechanism so that i side members connected b it may move freely in either direction. It will be also observed that the carria e release lever M may be operated indepen ently of the margin stop release lever 5.
The margin stops illustrated are in many respects similar to those previously known and used in the Royal machine and each stop comprises a body portion 15 of eneral trough like form having ears 16 an 17 at their ends which project below the stop bar and are connected by pins 18 and 19 respectively. The thin metal member 20 has its ends hooked about the pins 18 and 19 and lies in contact with the lower edge of the stop bar. The stop is held in adjusted position on the stop bar b means of a latch member 21 provided wit a nger piece 22 and having ears 23 intermediate its ends which are pivoted to the stop on an axis 24. The latch member also has a downwardly extending tooth ortion or detent 25 which engages between the teeth 26 of the stop bar 1 and holds the stop in its adjusted position. A spring 27 coiled about the pivot 24 fands to return the latch 21 to the Figure 2 position. Between the body of the stop and the latch member thus described and pivoted on the pivot 24 by means of ears at each side thereof is a bail member 28 normally forced downward by a. ring 29. One Aend of this bail member slias a downwardly extendin arm 30 provided with a in 31 at its en which fits in an elongate slot 32 near one end of a detent member 33 which comprises va cross bar 34 terminating in a sharp e ge. This detent member is pivoted on the pin 19.
The engaging portion of the stop is an ad- 'ustable screw 35 carried by the stop memr above described and locked in adjusted position by a set screw if so desired. The sto also includes mechanism for automatical y setting the stop surfaces a distance away from each other equal to one' letter s ace, such mechanisms being in themselves o d as shown for example in patent to L. C. Myers No. 947,450 granted Jan. 25, 1910. This mechanism comprises in the present instance an adjustable member 36 held in position upon the stop member by a screw 37 passing through an elongated opening in the member 36. Upon this member 36 is pivoted by a screw 38, an interponent 39 having an end 40 which may be moved into a position between the stop 35 and the center stop 42 on the frame of the machine. The interponent has an upturned end 41 having a cam portion in position to be engaged by the g'latch 21 when it is pressed downward to rclease the stop from the stop bar. Whenever A,the stop is released either manually or by the release mechanism, this interponent will Vbe swung to the Figure 6 position.
The detent member 33 is adapted to cooperate with detent mechanism on the frame of the machine which comprises a bracket 43 havin offset flangia 44 which is fastened to a fixe part of t e machine by screws 45 which pass through openings 46 in said bracket. Two do s 47 are mounted on pivots 48 and have t eir facing ends 49 separated by a slight space. A downward extension of each dog 47 carries a in 50 which rojects through a slot 51 in the racket memer. A spring 52 has a central portion coiled about a stud 53 carriedby the bracket and the ends 54 thereof engage the ins 50 to hold the dogs 47 normally in the igure 2 positlOll.
When the parts are in normal position such as shown in Figure 2, the mar in stop is locked to the said bar 1 and the etent 33 is in a plane above the ends 49 of the dogs 47.
.When it is desired to set a margin stop, the
endwise position. This will cause the release bar to rise to the position shown in Figures 3 or 8 and in this movement it will engage with the detent-25 and lift the same out of engagement with the teeth 26 of the stop bar. At the same time the release bar 2 will enga e the bail 28 and rock the detent member 33 ownward, bringing the bar 34 into the Figure 3 position so that as the carriage is moved in proper direction, the detent will engage one of the dogs 47 and cam the same downward against the tension of the sprin 52 until the end of the detent comes into t e s ace between the ends 49 of the dogs. In t is position it will be held so lon as pressure is maintained on the lever 5 auf at this time the carriage can be moved independently of the stop to any desired letter space osition. The same releasing movement o the latch 21 above mentioned will cam the interponent 39 to the Fi ure 6 position to automatically set the marginal stop at one letter space distance from the center stop 42. As soon as ressure on the finger lever 5 is released, the etent 25 will move downward into en agement with the stop bar 26 for holding t e stop in-adj usted position, and the spring 29 will return the bail 28 and detent member 33 to the figure 2 position, disengaging the same from the stops 47. Thus a marginal stop will be locked t0 the stop bar in position to stop the carria e in the selected letter space position.
n other words, let it be assumed that the machine frame is provided with the usual scale and the carriage with a cooperating pointer, and that it is desired to set the left hand margin stop at the point 20 in said scale. The stops are in locked en agement with the rack bar and the movable etents on the stops are disposed above the detent mechanism so that neither detent will engagesaid mechanism when the carriage is moved. The operator depresses the margin stop release at the same time will move the release bar to 1ever`-.5l which-Will` release the latches'of'ebo'th v margin. stopsfrom theirack. and *simultanem-ouslycooperate'withthe carriager'eleaselever 'M mechanism. :Simultaneously with the release .f 1.of;thef,latches,-thesdetents willl be wmoved to release the carriagefrom itsescapement downwardlyV into a position whereby" either A f one of themfwill engage thefdetent mechanism vil() ".uponemovement ofthe-carriage.
.The operator-without; releasing .thelever and the .ke M, moves the carriage tothe right .until the etent of the left hand stop engages the detenty mechanism. The l enga ement between the detento the left han rstop and .said detent f mechanism prevents further movement'of the stopvwith the carriage, but .permits the carriagev to .be further. `moved 4.by the operator. in' the same 'directions .-untiliY the gpointer on the carriage lregisters with the `number -on thescale.
