The present invention has been shown in the drawings as. applied to the' well known International electric writing machine, formerly known as "the Electromatic, which now is equipped with the key set stop mechanism disclosed in the aforesaid Crumrine application. This stop setting mechanism has been in commercial use for a number of years and is now well known in the art. Notwithstanding the selection of the specific machine and stop setting mechanism disclosed in the above application for the purpose of description, the present invention may be employed in any machine in'which the column stops are set by means of a key or similar element, whether such machine is operated by power or by hand. i

In Fig. 1 only such portions of the machine as are necessary to an understanding of the present invention have been shown. The reference numeral 10 generally designates the carriage on which isfrotatably mounted the usual platen H. The carriage is slidably mounted on front rail I2 and' rear rail l3'by means of suitable antifriction hearings in a well known way. The carriage is driven. in a letter spacing direction by the usual spring drum, generally designated l3, which-is-connected to the carriage by. means of a flexible tape it. The carriage is provided with a stop bar. I! on which :are rcbatably mounted the column stops it. a

These .column'stops are guided in slots in the bar 15 and are pivoted upon a fulcrum wirel'l slot in the rear vertical face of stop bar IS. The column stops cooperate with a tooth l8'a. (Figs.

1 and 2) formed in the end of the usual tabular Fig. 2 is a plan view of the tabulatingmecm lever. l8 which is pivoted at [9 (Fig. 2) ,to a relatively fixed part of the framework whereby said lever is capable .of a slight rocking movement in a counterclockwise direction (Fig. 2 to project the tooth IBa into the path of a set stop. Normally; thestops occupythe position indicated by the foremost stop in Fig. 4, but when set to active position are rocked in a counterclockwise direction to the position indicated by the reference numeral lliainl igs. i'to 5..

.(Figs. 1 and 4) which is secured in alongitudinal c 40 The tabular lever I8 is operated-to place the lug Na in the'path of the set column stops designated Ilia by means of a cam unit like [9, Fig. 1,

.tihually rotates in the which is connected by a link to a bell crank 2| pivoted on rod 22. The bell crank 2| is connected by a link 23 to a lever 24 (see Fig. 2 also) pivoted at 25 to a bracket 26 secured to the rear rail l3. The upper end of this lever has a tooth projecting irito a slot (not shown) in the lever l6 whereby, when the link 23 is drawn to the leftin Fig.2, the lever l8 will be rocked in a counterclockwise direction a slight amount. At

the same time, by means not shown, the usualing part of the cam unit Hi to rotatably. cooperate with the power roller '26. This power roller condirection of the arrow (Fig. 1) whereby the tabular lever |6 is operated Once upon each depression of key 21.

According to the present invention, improved means are provided to set the column stops l6 in a position to engage the lug |8a whenever the lever I6 is operated as described above. One form of the stop setting means is. disclosed in Figs. 1 to 5, inclusive. Figs. 3, 4, and 5 show on a large scale the stops and the parts of the sto setting mechanism which cooperate with the stops.- Secured to the top surface of a plate 30, which is utilized as a cover for certain portions of the mechanism located in the rear part of the machine, are brackets 3| on which is pivotally mounted a frame 32 resembling a bail. One of the brackets 3| has secured thereto a hub 3|a through which passes a shaft 33 on which the frame 32 is loosely pivotally mounted, the shaft 33 being secured against rotation by means of a set screw 3|b in-the hub 3|a. The frame 32 is urged in a clockwise direction (Fig. 4) by means of a torsion spring 34, one end of which is passed through a hole drilled diametrically of shaft 33,

while the other end is hooked around one arm of the frame 32. The frame 32 is also providedwith a bent-over lug 32a carrying an adjustable stop screw 32b which cooperates with the under surface of the plate 3| (Fig. 4) of the frame 32.

Slidably mounted onthe frame 32 by means of studs 35 is the stop setting head comprising a 'r-shaped member 36. The T-shaped member 36 is slidable in a direction parallel with the movement of the carriage whereby under certain circumstances said member may be moved by the carriage as will be made .clear hereinafter. Normally the T-shaped member 36 is held in a central position by means of two opposed springs 31 which are anchored T-shaped memberand crossbar of frame 32.

The T-shaped member is formedwith two

lugs

36a and 36b. Normally the springs 31 hold the member 36 in such a position that, when the frame 32 is rocked in a counterclockwise direction (Fig. 4), lug 36a will rockone of the stops l6 to the position designated by the reference numeral 161'. During a subsequent tab'ulating operation initiated by the depression of the key 21, the set stop-Mia will engage tooth |8a and the carriage will be arrested in a position corresponding to the one which, it had when the stopl6a was projected to-active position. The stop screw 32b is adjusted so that normally the frame '32.

to a. lug formed in the two lugs formed in the the tension of one or to limit clockwiserotation 4 occupies the position shown in Figs. 3 and 4 in which there is a small clearance between the end of the lug 36a and the unset stops, so as to permit the carriage to move freely'without interference between the lug 36a and any of the unset stops l6.

For the purpose of operating the setting head 36 to set a selected stop i6 to active position, thereis provided an operating member in the form of an arm 36 which is rigidly secured to a shaft 33 journaled in lugs 36a formed in plate 30. The upper end of the arm 36 has a tooth 36b confronting the end of the lug 36b. Itis evident from Figs. 3 and 4 that the rocking of arm 38 in a counterclockwise direction 'will cause the frame 32 to be similarly rocked by engagement of the tooth 36b with the tooth 36b. Thus, the T-shaped member 36 acts as an interposer between the arm 36 and any stop |6 that may be in position to be set.

The arm 33 is operated bymeans of a stop setting key 46 (Figs. 1 and 2) which is' pivotally mounted on a fixed bracket 4| and is connected by link 42 to an arm 43 securedto the shaft 33. Thus, whenever the key is depressed, the frame 32 will be rocked in a counterclockwise direction, Figs. 1 and 4. I I

It may happen that after the key 43 has been depressed and the lug 36a on member 36 is still between two unset stops the carriage may be moved. For example, in depressing the stop setting key 43, theioperator might-also accidentally depress theusual carriage return key (not shown). Obviously, if the carriage begins to move while the stop setting head is between two unset stops, damage-to some part, such as the head 36 carriage'return tape might break. Owing to the fact thatthere isa very limited space between the or the column stops might result, or the stops 6, it is not possible to make the tooth |6a strong enough to stand such abuse.

If it should happen that the carriage starts to move while a stop is being set, one of theunset stops adjacent the one engage the side of the lug 36a and cause the stop setting head 36 to travel with the carriage against the other of springs 31. After the carriage moves a little less 'than a letter space, the lug 36b will clear the end of the lug 36b and permit spring 34 to rock the frame 32 back to the position of Fig. 4. Fig. 5 shows the position of the head 36 after this has occurred and, with the stop setting key still held depressed, it will be seen that the spring 34 has rocked the frame 32 to completely withdraw the tooth 36a of head 36 from between the unset stops l6 whereby the carriage can now move freely without interference with mechanism.

Thus, it is impossible any part of the stop setting tov damage either the stops |6 or the stop setting mechanism or break stop l6.

When the stop sending key 4|) is released, a spring 4. coiled around a shaft 39 and engaging the arm 43 rocks th: arm 36 back to the position either of' which is being set will -of Figs. 3 and 4, permitting the tensioned spring 3'Ito'restore the stop setting head 35 tothe position at Fig. 3.

v -The'mechanism shown-in Figs. 1 to 5 has the advantage of-disen'gaging the stop setting head from the stops 16 very quickly, it being effective ofthe head 35 from the stops is dependent upon the relative thickness of the

lugs

36b and 38a.

- Thus, by making either of the lugs 35b, 33a very sition of Fig. 4, in which case the carri thin, the disengagement of the head 35 from the stops Hi can be effected with considerably'less than a letter space movement of the carriage. However, there is a practicallimit to doing this as the parts must have thenecessary mechanical strength. Conversely, the lugs 36b, 33a may be made thicker to require a longer movement of the carriage before disengagement of the setting head takes place.

Th construction shown in Figs. 1 to.5 has the disadvantage in that it depends upon the spring 34 to withdraw the stop setting head 36 from between the stops. Obviously, if the spring 34 broke, it is possible that in consequence of the friction between the side of an unset stop and the lug 36a, 'the -stopsetting head and the frame 32 might be held against restoration the poe would move the head 35 until further movement of the head is prevented by the screws 35 after which the carriage would be blocked from further movement. Since the carriage would be permitted to acquire some momentum before the screws 35 finally stop further movement of the carriage, the tendency to breakage of the head. would be greater in consequence of the greater shock with which the carriage would be stopped. Accordingly, inFigs. .6, 7 and 8, there is shown a form of the mechanism in which the movement of the carriage is utilized tov cause the stop setting head 36 to be positively cammed from between the unset stops it before the carriage has moved any appreciable amount.

In Figs. 6 and 7 the stop setting head consists of an arm 45 having a toothed portion 45a I adapted to engage the unset stops it and pro- .ject themto the position i6a. This arm 45 is integral with" a hub 46 which rotatably and slidably mounted upon a shaft 41. This shaft 41 is supported by brackets 3ia secured to the underside of the cover plate 30. The shaft 41 is prevented from moving longitudinally by means of collars 41a. Springs 48 interposed between the hub 45 and the collars 41a hold arm 45 in central position.

Also secured to the hub 46 is an arm 4301i which is pivotally mounted, near itsmidpoint, a lever 50. The left-hand arm (Fig. '7) of lever 50 projects into a cam slot id formed in a block 5i secured to the top surface of the plate 33. The right-handarm of the lever 50 has a hole in which loosely slides a pin 52 in the left-hand end of a link '53, which is pivotally connected, at its right-hand end, to an operating member in the form of an arm 54 secured tosha ft 39. The

right-hand arm of lever 50 also has a bent-over lug 50a projecting through the plane of the link A spring 55, anchored to the lever 50 and to an ear (not shown) formed, in the plate 30, tends to rock the lever 50 in a clockwise direction edge or the link 5:.

'43 and hence arm.45 will be similarly rocked, the

spring 55 and lug" 50a preventing bendingof the toggle. Thus -ordinarily the link 53 and the arm of lever 50 actlike a rigid

link interconnecting arms

49 and 54.

- The arm 45 is provided with a bent over lu 45a having a stop' screw 56 which engages the top surface of the plate'3il to limit clockwise movement of the

arms

45 and 49. A'spring 51, connected to arm 45 and a pin-on the plate 30, normally holds the arm 45 in the position of Fig.

. -7 with lug 45a clear of the unset stop i6.

With reference to Fig. 8, it will be noted that l the left-hand arm of lever 50 normally occupies a position close to the deepest portion of the cam slot 5ia. When the shaft 39 is rocked in a counterclockwise direction to set a selected stop the left-hand arm of lever 50 is moved toward the block 5| and slightly upward until the lever practically touches the deepest portion of the cam slot 5ia. If, while the stop setting key is held depressed, the carriage should be moved, the contact of the unset stop on one side or the other. of the tooth a,.according to the direction in which the carriage moves, will cause the arm 45, hub 46, and arm 49 to move longitudinally of shaft 41 against'the tension of one of the springs 48. This will cause the lever to be moved bodily in the same direction, thismovement being permitted, by the length of the lug 50a and the sliding connection between the pin 52 and the right-hand arm of lever 50. However, the shape of the cam slot 5ia is such that, when this movement takes place, the lever 50'wil1 be cammed in a counterclockwise direction (Fig. 7) against the tension of the spring 55, thereby bending the toggle comprising link 52 in the right-hand arm of lever 53 and moving arm 45 back to the position of Fig. 7. The spring 51 is considerably.

superior in tension to the" spring and, once the pin 52 has moved a small amount above a line drawn through the pivots for link 52 to arm 54 and forlever '50, the spring. 5'! will take eifect to assist cam 5ia in bending the toggle sufliciently to move the lever 45' to the position of Fig. 7, notwithstandingthe fact that arm.54 may still be heldin operative position by the operator holding down the stop setting key 40. Thus, the arm I 45 is positively forced out from between the unset stops and remains in the position of Figs. 6 and '1.

As soon as the stop setting key is released, the arm 45 remains immovable since it has already moved as far in a clockwise direction as it can and is being held in this position by the spring position when the stop setting key is released which requires a relatively small force. I

.1to5,assoonas'thestopsettingheadlliswlth-- In the form of the invention disclosed in Figs.

drawn from between the stops, the spring holds the head in the position of Fig. 5 and prevents it from being drawn back to the central position by the active spring 31. As long as the stop. setting key- II is held depressed, the head will remain in this position and will be restored to the central position only when the stop setting key is released. Thus it is impossible for the stop setting head to re-engage the unset stops once it has been withdrawn. In the form of the invention shown in' Figs. 6 to 8, the stop setting head, which in this case comprises the arm 45, is free to be returned to the central position by the compressed spring 48. The result is that the head 45 returns to the central position as soon as it is moved clear of the unset stops; however, owing to'the spring 51 being superior to the spring 55',

the head is held in the normal position clear of the stops and cannot be again moved to engage an unset stop until the stopsetting key has been released. Thus in the form of the invention shown in Figs. 6, '7, and 8 it is impossible to reengage the head after it has once been disengaged from the unset stops. It is quite possible,- however, that the spring 51 might become weak or break so as to permit the head 45 to become drawn back between the unset stops in consequence of the tension of spring 55. This will do no harm, however, since, with continued movement of the carriage, the head will be immediately forced outfrom betweenthe unset stops by the cam Ma and the only eiIect produced might be a continuous reciprocation and.

oscillation of the head on its shaft 41. The cam 5| a is so shaped that it will always move the head 45 out from between the: stops independently of the spring. Normally both the spring and the cam work together so closely that it might be "difficult to determine which of these elements is most responsible for the withdrawal of the head from between the stops. Thus the cam 5Ia acts not only as a controlling member for-rendering the withdrawing means eflective,

., but it also acts by itself as a withdrawing means in the event of sticking of the parts or breakage of the spring 51.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single embodiment,

it will be understood that various omissions and substitutions and changes in the form and de-- tails of the device illustrated and in its operation may beflmade by those skilled in the art without departing from the spirit'of the invention.
