KocA STOP OPERATING MECHANISM 2 Sheets-Sheet 2 Filed May 20, 1935 MAJU Patented Mar. 22, 1938 UNITED STATES PATENT orrlcs STOP OPERATING MECHANISM Application May 20, 1935, Serial No. 22,301 5 Claims. (01. 197-179) This invention relates to typewriters and particularly to an attachment therefor. More specifically, the invention relates to stops carried by the carriage and adapted to co-operate with 5 a stop member operated by the depression of a key to engage the carriage stops, to stop the carriage at predetermined positions.
An important object of the invention is the provision of a stop adapted to be adjusted in 1 upper, non-engaged position or lower, operative, engaged position, said stop being positioned by the depression or operation of a co-operating depressing member.
Another object of the invention is the provi- 15 sion of a stop setting element for setting any one of a plurality of stops in a predetermined position.
A further object of the invention is the provision of a plurality of slidably mounted elements for selectively depressing stops into position to 20 be engaged by a stop member.
Numerous other objects and advantages will be apparent throughout the progress of the following specification,
The accompanying drawings illustrate a se- 25 lected embodiment of the invention, and the views therein are as follows:

The particular typewriter herein shown for the 40 purpose of illustration is that of the popular, well known Woodstock typewriter, but it is to be understood that the invention is applicable to typewriters of other make. The typewriter or typewriting machine herein illustrated has a frame ll upon which a carriage i2 is mounted for transverse movement on ways l3. A circular bar or rod l4 extends between the end plates 15 of the platen carriage, and this bar is rigidh at- 50 tached to the end plates l5, being held from rotation. A. plurality of column stops l6 are journaled on the bar I4 and normally project upwardly therefrom in normal inoperative position, as shown in Fig. 3. The stops it are arranged 55 substantially throughout the entire length of the r the opening I 8.
bar l4 and are spaced one from another by letter space distances.
Each stop l6 comprises a metal body ll having a circular receiving opening or hole l8 through which the bar M extends. The end i 9 of the body 5 is cut out, as indicated at 20, and extends into The body I! of the stop I6 is split or cut, as indicated at 2!, Figs. 3 and 5, to form an extending arm or end 22. The stop is preferably cut or stamped from metal and is 10 hardened sufiiciently so that the extension or leg 22 will be relatively springy and capable of spreading a predetermined distance so that it may be easily and readily slipped over the rod M. V
The stops 3 are movable in an upward inoperative position, as shown in Fig. 3, or into a downward operative position, as shown in Fig. 5. Upper and lower bars 23 and 24 prevent lateral movement of the stops as well as limiting the upward and downward movement thereof. The stops l6 are arranged in cut-out notches or spaces 25 and 2B in the bars 23 and 24, the slots 25 and 26 being in alinement with each other. The stops l6 are held in either of their adjusted positions by means of teeth 27 formed on the 2 extension or leg 22 of each stop. These teeth co-operate with and are adapted toengage the opposite sides of a rib 28 formed on the circular bar [4. Due to the pivoted and yielding connection of each stop It with the bar I 4, the stops 30 may be readily and quickly removed and applied to the bar M. The stops I6 may be moved from inoperative raised position, as shown in Fig. 3, to operative position, as shown in Fig. 5, by a finger 29, Fig. 3, connected to a bar 30, which 3 moves vertically in a housing 3|. The finger 29 is depressed by the operation of a key 32, Fig. 1. When the stop is in down position it is adapted 'to engage a stop member 33 which is also slidingly mounted in the casing 3| and is raised up- 40 wardly by the depression of a key 3d.
The particular construction of the stop N3, the method of depressing the same by the finger 29, and the means for operating the stop member 33, are disclosed and claimed in applicants co-pending application, Serial No. 22,300, filed concurrently herewith. A dififerent type of a stop and means for depressing the stop are also disclosed and claimed in another of applicants co-pending applications, Serial No. 22,299, filed concurrently herewith, both of the aforesaid'co-pending applications being assigned to the present assignee.
Very often the operator or typist, particularly when writing various forms of letters, finds it desirable to have certain stops set to conform with these regular forms or routine and, therefore, it is more convenient to throw the stops by hand. In the aforesaid co-pending application, Serial No. 22,300, some of the stops are provided with an extension or handle having a colored knob. However, it is even still more convenient to have slidable means co-operating with the stop whereby any stop may be depressed as desired, without resorting to the operation of the key lever. This latter construction forms the basis of the present application, and comprises manually depressible members 35, each of which has a finger piece or key 36 and an elongated vertically extending plunger bar or rod 31. Each member 35 is mounted in a metal clip 38, Fig. 4, which is preferably stamped and formed from a single piece of metal and comprises a base portion 39, which is adapted to abut of the bar 23, Fig. 5.
An upstanding body portion M, forming part of the member 33, is provided with alined openings through which the body or plunger portion 3? extends. A pin 55, Fig. 3, limits the upward movement of each member 35, and a spring 26 arranged between the bent ears 37 and 48 urges the member 35 upwardly, the spring 46 engaging a washer 49 which engages the pin 45, Fig. 5.
Ears or arms 5!) are bent up from the plane of the member 39 and provide means for shifting each of the elements along the bar 23. A spring clip 5! is fixed to the back of the body portion 4% in any convenient manner, such as by screws 52, for holding each of the members 35 in adjusted or shifted position and preventing unauthorized side movement. A detent 53 is formed in the spring metal member 5|, Fig. 6, and is adapted to engage the spaces 25 in the bar 23 to hold each of the elements 35 in its shifted position. The member 5! being made of spring metal, will give suiiiciently to permit the members 35 to be easily slid along the bar 23, but at the same time prevents the members 35 from moving due to jar or vibration in operation.
The invention provides manually operated members slidably mounted along the upper bar whereby the operator is free to depress any of the stops id as desired. To assist the operator the knobs or keys 36 may be colored dilferently to conform with the routine or form which the operating a member 35 which has a red knob 35.
In still another instance, the operator may change to a form of letter writing requiring blue knobs to be shifted. The knobs may be made any color, such as red, blue, yellow, etc., so that the operator at a glance can set a stop conforming to the type of work being done. In addition, the operator is free to set any other such stops as are desired by the operation of the key lever 32. The invention, therefore, provides selective means of broad adaptation for conveniently setting the stop position of the carriage to conform with the various classes or forms of material the operator is writing. Also, the operator is free to shift stops manually as desired or required, and the various coloring of the knobs indicates quickly the stops which are to be depressed for the certain form or routine. Changes in the routine or form, of course, can be changed at will because the members 35 are slidable. The elements 35 can be very economically manufactured, are efficient in operation and can be easily operated or manipulated.
Changes may be made in the form, construction and arrangement of the parts without departing from the spirit of the invention or sacrificing any of its advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims.
The invention is hereby claimed as follows:
1.
