GEORGE A. SEIB, OF ILION, NEW YORK, ASSIGNOB TO REMINGTON TYPEWRITER COM- PANY, or 111011, new roan A CORPORATION OF NEW YORK.

TYPEWRITING IiIACHINE.

Application filed March 24, 1822.

To all whom it may concern:

Be it known that I, GEORGE A. SEIB, citizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to tabulator mechanism.

The main object of my invention, generally stated, is to provide simple and eflicient means whereby partsof the tabulator mechanism may be readily assembled and mounted in the machine and may be readily detached therefrom when desired, thus re-g ducing the cost of manufacture and facilitating detachment, replacement, and the making of repairs.-

To the above and other ends, which will hereinafter appear, my invention consists in the features of construction, arrangements of parts, and combinations of devices set forth in the following description and par ticularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the, different views.

Figure 1 is a fore-and-aft vertical view of the lower portion of an improved No. 10 Remington machine modified to incorporate my invention therein.

Figure 2 is an enlarged detail side view of a universal release bar and the means for detachably mounting it in place, together with some ofthe associated parts.

Figure 3 is a transverse sectional view of the same taken on the line 33 of Figure 2 and looking in the direction of the arrows at said line.

Figure 4 is a' detail perspective View of the universal release bar and some of the associated parts.

I have shown my invention included in an improved No. 10 Remington machine in which it may be readily embodied without materially changing the structural features of said machine as they now exist, and have only shown so much of said machine as is necessary to illustrate the invention in its embodiment therein. It should be understood, however, that the invention may be included in other styles of machines; for

Serial No. 546,316.

example, the invention may be included in an improved No- 11 Remington machine, as Wlll hereinafter appear.

The frame of the machine comprises a .in which to mount such column selecting stops, and as is customary in the improved No. 10 Remington machine. The frame 3 is detachably connected to the frame of the machine by screws 4 which secure the tabulator frame to the base screws (not shown) 3 to the top plate. Upright stop actuating levers or members 5 are pivoted to the tabulator frame, and coact with the selecting stops (not shown) to project them into the paths of the column stops onthe carriage. Each'lever 5 is pivoted at 6 to a forwardly extending link 7 pivoted at its forward end, as at 8, to an actuating member or angular lever 9; This lever carries a forwardly extending finger 10 which projects through a slot in a key stem 11 carrying a tabulator 1 key 12 at its upper end. Each stem works 1, and by other wh1ch secure the frame in guide slots in the sheet metal guide plates I 13 and 14 fixed to the base of the machine, and is limited in its movements in opposite directions by felt pads a and b. The usual springs (not shown) are employed to return the levers 5 with to normal position.

In order to effect a release of the carriage from the control of its escapement mechanism at each actuation of a abulator key, I provide a universal release bar 15 which extends across the machine in the paths of the 7 rear edges 16 of the depending portions of' the levers 9. The levers 9 and the universal bar 15, as will hereinafter more pear, are pivoted on a pivot rod or cross bar 17, which in the present instance is in the nature of a rock shaft. A depressionof a tabulator key 12 is effective not only toactuate the companion lever 9 and stop operating lever 5, but also to swing the universal reand the parts connected thereclearly aplease bar rearwardly. Two depending ears 18 on the bar 15 have pivotally connected thereto, at 19, rearwardly extending links 20. The rear ends of these links are pivoted at 21 to arms 22 secured to a rock shaft 23. Said shaft is pivoted for rocking movement at 2 1 to bracket arms 25 on the base of the machine. One of the arms 22 has a forwardly projecting arm 26 connected to the usual carriage releasing devices, not shown.

In the improved No. 10 Remington machinev the rock shaft 17 is replaced by a be; fixed to the base 1, and on this bar is pivoted not only the universal release bar and the stop actuating levers but also two case shift levers at opposite sides of the machine," such levers being united by connections extraneous to the center of the pivot rod on which they are mounted. In the present construction I replace the fixed pivot rod, formerly employed, by a rock shaft 17, the latter being detachably mounted and pivotally supported at its ends by coned pivot screws 27 threaded through tapped openings in the base, and held in position by lock nuts 28. Each end portion of the rock shaft is slabbed off on opposite sides at 2-9 to provide-a projection 30 which is angular in cross section; a shoulder being formed where each projection joins the shaft. Each of these projections 30 is received and fixed in a correspondingly shaped opening in a case shift lever 31, pivoted at its rear end, as at 32, to an upwardly extending link 33 connected with the usual shift rail. Each lever 31 carries a lateral projecting pin 34: grooved to, receive the hooked end of alink 35. The rear end of each of these links is connected to one end of a contractile spring 36 connected at its other end to a pin 37 fixed to the base. The force of these springs tends to counteract the weight of the platen. 7

It will be seen that the rock shaft 17 forms a rigid connection between the two case shift levers along the pivotal axis of said levers where the connection is most effective to cause the levers to move together, the fixedly connected levers and shaft constituting in effect a case shift frame.

In accordance with my present invention I provide means whereby the levers 9 and the universal release bar 15 may be readily mounted in place for pivotal movement on the rock shaft 17. Thus at different points throughout the length of the rod I form circumferential bearing grooves 38, the number of such grooves depending on the number of levers 9 employed. The two end grooves 38 receive hook-like bearing members 39, each formed integral with an upwardly extending supporting arm formed as a part of the bar 15 at an end thereof. The width of each groove 38 preferably corresponds substantially to the thickness of the member 39 which receives a bearing therein. In this manner the members are maintained spaced apart and are prevented from displacement along the rod 17. Each part 39 may be readily hooked over the rod 7 and seated in its bearing groove 38, and

in cross section, and is adapted to straddle.

and embrace both sides of the member 40 that carries it. The side members 41 of the latch are united at 4.2, and are spaced apart at every other portion thereof so as to receive the associated arm. 10 between them and enable the latch to turn on a pivot 43 (by which it is connected to. the arm) from the full to the dotted lineposition in Fig. 2,

or vice versa. The upper edge 4A of each slde plate or member 11 is curved concentrically with its pivot 13, and when the latch is in the locking position said edges are ad acent to the body. portion of the rod 17 on opposite sides ofthe companion groove 38. This prevents the member 39 from moving up off the rod and out of its bearing groove.

In order to prevent accidental displace ment or the latches from their locking position, I have provided each latch with a rounded projection or detent 45 struck up and extending inwardly from one side of the latch and adapted, when the latch; is in the locking position to seat itself in a holei or depression 46 in the arm 4L0. Each of the lovers 9 in a like manner is provided on its upright arm with a hook like bearing portion 4? adapted to be hooked over the rod and seated in a bearing groove 38 therein and to receive pivotal n'lovement thereon. If desired, each lever 9 may be provided with a relatively movable retaining latch 41 of the character described, but this is a deemed unnecessary in the present instance since the construction and the relative arrangement of the parts are such that there is little liability of the levers being accidentally detached from their supporting rod. However, the levers may easily be mounted in place or disconnected when desired, thus facilitating assembling the ma chine and reducing cost of manufacture.

I have shown the usual shift lock key a8 in addition to a shift key l9 on thelefthand lever 31. The key 48 is carried by a locking member 50 pivoted at 51 to said.

lever 31, and carries a hook-like engaging member 52 adapted to engage the co-operafive fixed member 53 on the base of the machine.

In the present instance I have shown five tabulator keys 12 and five levers 9 controlled thereby for controlling a corresponding number of stops, as in the improved No. 10 hemington machine, for selecting columns. It should be understood, however, that a greater number of levers 9, say ten, may be mounted on a bar 17 with more bearing grooves 38 therein and a corresponding number of keys 12 and levers 5 may be provided to control denominational selecting stops for denon'iinational selection, as in the No. 11 Remington machine, instead of column selection, as in the No. 10 machine.

Various changes may be made without departing from my invention as defined in the accon'ipanying claims and certain features thereof may be employed without others.

lVhat I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine, the combination of a cross bar having a peripheral bearing groove therein, a depending arm having a hook-like bearing portion seated in said "lplieral bearing groove, ant, retaining member carried by and straddling said arm am; coacting with the periphery of the shaft outside and on opposite sides of said periphgroove to prevent a displacement of the transversely of the cross bar, said reing member being movably mounted on arm for movement into and out of reg position, whereby the arm may be readily dismounted when the retaining member is open by a displacement of the arm transversely of the cross bar.

2. In a typewriter or like machine, the combination of a cross bar having a series of peripheral grooves cut therein at different points in itslengt-h, and a series of de pending arms each having a hook-like bearing portion closed at its upper side and open at the bottom and seated in one of said grooves for support and pivotal movement on the cross bar and prevented from displacement along the bar by the walls of its groove, the arms being thus detachably mounted and maintained spaced apart on said bar, one or more of said arms carrying an independently movable retaining member movable to open and close the mouth of the hook-like bearing thereof, to prevent the associated arm from being detached or enable it to be detached depending on the position of its retaining member.

3. In a typewriter or like machine, the combination of a cross bar having a series of peripheral grooves cut therein at different points in its length, a series of depending arms each having a hook-like bearing portion closed at its upper side and open at the bottom and seated in one of said grooves forv support and pivotal movementon the cross bar and prevented from displacementalong the bar by the walls of its groove, the arms being thus detachably mounted and main tained spaced apart on said bar, one or more of said arms carrying an independently movable retaining member movable to open and close the mouth of the hook-like bearing thereof, to'prevent the associated arm from being detached or enable it to be detached depending on the position of its'retaining member, each retaining member comprisin a sheet metal device folded into substantia ly Ushaped formation in cross section and straddling the arm'by which it is carried, and detent means for holding said retaining memlber against accidental displacement from its active position where it closes the mouth of the bearing and prevents an upwardly.displacement of the as sociated arm. 1

4. In a typewriter or like machine, the combination of a key actuated rock shaft having a series of circumferential grooves cut therein, and a plurality of depending arms each having a hook-like bearing portion closed at its upper side and open at the bottom and seated in one of said grooves to detachably support its depending. arm and pivot it on said rock shaft, one or more of said arms having a relatively movable retaining member thereon adapted to open and close the mouth of the associated bearing and prevent an upward displacement of the companion arm from the shaft.

5. In a typewriter or like machine, the combination of a case shift frame comprising a rock shaft forming a rigidly connected vpart of said frame and by which it is supported for pivotal movement, and a series of arms each having a hook-like bearing portion seated on said rock the associated arm is detachably supported to pivot on said shaft.
