GEORGE A. $1313, 015 ILION, NEW YORK, ASSIGNOE'L T0 REMINGTON TYPEWRITER GOM- CORPORATION OF NEW YORK.

'rYrE-wnmms MACHINE.

To all whom it may concern Be it known that I, Gannon A. SE11}, citizen of the United States, and resident of .ll'ion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in 'lype-Writing Machines, of which the following is a specifi cation.

My invention relates to typewriting machines and it has for its object to provide improved dead key mechanism for such machines. Specifically stated, the principal object of the invention is to provide, in a case. shift typewriter, means whereby one of the types on a type bar can print an accent mark, for example, whiclr requires no letter space, and the other type. on the same type v bar can print a character that does require letter spacing, and that the escapement will he operated in one case. position and not in the. other, the. ribbon vibrator, it present, be ing operated in both instances.

One form of my invention is illustrated in the. accompanying drawings, in which- Figure 1 is a partial front to rear section of a. typcwriting machine having my inven tion embodied therein.

Fig. 2 is a fragmentary enlarged view of a portion of the same but with the ribbon mechanism in operated position.

Fig. 3 is a rear elevation in section about on the, line of Fig. l.

Fig. l is a fragmentary plan view oi that portion of the mechanism which is in the base. of the machine.

, I have shown my invention embodied in a. machine which in most respects is like the No. 10 Remington typewriter. The mainframe of this machine. comprises a.base 1 from which rise posts 2 which support a top plate 3, and on said top plate there is a. carringof which I have shown in the drawing onl the roller platen l and feed rack 5. Said feed rack meshes with a feed pinion (3 on the front end of a shaft. which at its rear end carries an. oscapement wheel 7, said shatt, being journalcd in a. housing 8 mounted on the top plate 3. The escapcment wheel 7 is controlled by feed dogs 10 1nounted on a (log rocker 11 suitably pivoted in the stationary framework and having an arm 12, which is connected by a link 13 with an arm 14 mounted on a rock shaft 15, which is pivoted at its ends on pivot screws Specification of Letters Iatent.

16 secured to the side bars of the base 1. Said rock shaft 15 has arms 17 projecting rearward therefrom. Fig. i, and, by means of links 18, supporting a universal bar '20. Said universal har lies beneath the printing key levers oi the machine, t'our of which are partially shown in the drawings, three of these being special key levers 21 and the fourth an ordii'iary key lever 21. The rock shaft 15, being thus connected to the univer sal bar, is operated by all of the ordinary printing keys and it may, therefore, be termed a universal member. The key levers 21 are pivoted. to a slotted plate 22 and are provided with returning springs I have not deemed it necessary to show these key levers in full because they arc' a part of the well-known Remington machine.

In that machine each of said key levers has a depending lug consisting of a vertical having two types 26 and 26 thereon, which bars when one of the keys is operated are adapted to strike against the front face of the platenl. In the normal position of the parts the lower one 26 of the two types strikes the platen and this is therefore the lower case type, and when theplaten is shifted upward the upper case type 26 strikes the platen. The case shift mecha nism of the Remington machine comprises a shift rail 27, Fig. 1, on which runs a. roller or wheel mounted on the shiftable' platen frame of the machine-and said rail 27 can by means not herein fully shown, but which is shown in my prior Patent No. 1,203,795, dated November 7, 1916. Said railis carried by two irregularly-shapcd arms or brackets 28, and each of said arms or brackets is at its lower end rear arm of a lever 31., Said levers are pivoted on a cross rod '32, each of them extending to the keyboard of the machine. where it provided with a. case shift key 33; and the two levers 81 are con .ncctod by a heavy transverse bar 34 to cause v with said universal bar by prior patent above referred to; but for the sake of simplicity I have here shown more or less conventionally a vibrator 35 having its stem 36 pivoted to the forwardly directed arm of a bell crank 37, which bell crank is pivoted at 38 to a bracket 40 secured to the shift rail 27. Said bracket has an upwardly and forwardly extending arm terminating in a guide ll for the vibrator. The depending arm of the bell crank 37 is connected by a link 42 with the upper end of a lever 43 of the first order, which is pivoted at 44 to lugs 45 projecting from the stationary part"of the machine, these lugs in the No. 10 Remington projecting from the type bar segment 45. In Fig, 3 the lever 43 is shown as a built-up frame comprising two lever arms spaced apart and connected at their lower ends by a cross rod 46. this being the form of lever employed in the ribbon mechanism set forth in my said prior patent. In said patent the link &2, bell crank 37 and bracket 40 are replaced by a more complicated mechanism adapted toprovide'for the use of a bi-color ribbon and for throwing the ribbon out of operation for mimeographing; and some such complete ribbon mechanism is preferably employed, although the simpler form shown in this application can also be employed.

The rod 46 passes through an open-ended slot 47 in a lever 48, which is pivoted on a pivot screw 49 to the side of the arm 14. The lever 48 has a rearwardly directed arm from which an ear 50 is bent off beneath the arm ll and through said arm 14 is screwed an adjusting screw 51 having a lock-nut The lower end of said screw 51 is adapted to contact with the ear 50 in such fashion that when the shaft 1.5 is rocked the arm 14 is thereby moved downward and the lever 48 partakes of the motion of said arm 14 and moves the rod 46 toward the rear of the machine, thus moving the upper end of the lever l3 toward the front of the machine and operating the vibrator. The 1e ver 48 can be operated independently of the arm '14. however; said lever in such case turning about its pivot 49 and being restored to its normal relation to said arm 14- by means of a spring 53; the construction in this respect being like that shown in my prior patent and at present employed in the No. 10 Remington machine.

' In order to operate the lever 48 and the ribbon mechanism independently of the arm 14 and the esrapement mechanism, said lever 48 is connected by means of a link 54 with a secondary universal bar 55 supported at its ends by arms 56 which are pivoted on the cross rod The link 54 is connected means of a pin 57 passing through a slot 58 in a bracket 60 secured to the universal bar 55 near the middle of the machine. The construction is such that it said universal bar 55 be depressed the lever 48 will be operated; but if said lever be operated by the universal bar :20 acting through the arm 14, the link 54 can move downward without disturbing the universal bar Said universal bar 55 is provided with returning springs (31 and with stops 62 which limit its upward motion by contact with the base-frame.

In case it is desired to make any key a dead key the screw 2% of that key lever is either removed entirely or is screwed up so high that it will not operate the universal bar 20, and underneath that same key lever another screw 63' is screwed up through the universal bar 55 into such position that a.

depression of said key lever will, through said screw, operate said universal bar 55 and will thus operate the ribbon vibrator but not the eseapement. just described is that at in the Remington machine.

In order to provide for making any desired printing key a live key in lower case and a dead key in upper case, or vice versa, I remove entirely from that key lever the screw 24 and place beneath said key level one of the screws 63; and I provide means for connecting that key lever with the rock shaft 15 in one position of thecase shift mechanism and for disconnecting said key lever from said rock shaft in the other position of said mechanism. To this end'I replace the screw 24 with a screw '64 having a. wide lat head (35 and I'pivot to the upper side of the rock shaft 15 a coupler, here shown as an arm or plate 66 a apted to be turned in under the head 65 of the screw or to be turned to another position away fromsaid screw head. Said plate or arm v66 has a hub 67 through which passes a pivdt screw 68 screwed into the shaft 15- so as to allow the arm (36 to be turned in right and lefthaud directions, but so that in case said arm is depress-ml by the head 65 the shaft 15 will be rocked to actuate the ribbon vibrator and the escapcmcnt in the same general manner that it is rocked by the universal bar 20 when depressed by an ordinary printing key lever. If the arm 66 is not in register with the screw head (35 then a depression of the key lever carrying the screw head will fail to-rock the shaft 15 and the cscapement will remain at rest. But at this stroke the .ribhon vibrator will be actuated through the screw 63, secondary universal bar 55, link 54, lever 48 and frame 43.

The arm 66'can be connected with the ease shift mechanism in various ways, the means here shown consisting of a wire 70 pa. 'ing through a hole in the arm (36 andat its upper end secured to a rightanglcd bra -ket 71 secured, as by screws 72, to one of he shift brackets 28. In the present instance the wire is shown threaded and provided The arrangement present employed with two nuts'73, one on each sideof the bracket 71. The wire 70 is bent near its lower end as shown at 70 in. Fig. 3 so that when the platen is in lower case position the part of the wire that projects beneath the plate 66 is inclined toward the right and when the shift key is operated and the bracket 28 is moved upward this wire is drawn throughthe plate 66 and cams said plate toward the right. WVhile in the present instance the wire is bent at its lower end toward the operators right so that when the case shift key is depressed the plate 66 will ,he swung toward the operators right it will be swung out from under the screw head and be understood that said wire may be bent toward the left to swing the plate toward the left, if desired. As herein shown, this particular plate66 18 at the extreme left-hand side of the machine and in the lower case position of the platen it extends straight toward the rearibf the machine with its rear free end lying beneath the head ()5 of the screw (Bl. In this position of the plate its associated key 21 is la live kev; but if the case shift key be de )ressed this plate will be swung off to the oiservers left and will in that position of the parts this willbe a dead key and at that time'the eseap'ement will not be operated. The type barthat is operated by this key will have an ijaccent mark "on it for printing in the uppercase position and some other character that re quires letter spacing for lower case posit-lOIl. 5

In case it is desired to have several of these keys av screw-64 and a coupler 66 are provided for each such key. and the several couplers can all be operated byone wire 7 O. In the present instance, I have shown associated with three keys three of the coupler plates 66 all connected together by a link or JHI' 74 pivoted to each of said plates as by a pivot screw 75. The construction is such that when one of said plates is swung towand the right or toward the left by the shift mechanism the remaining plates will also be swung in the same direction.

It will be understood that any key equipped in this way can be made either normally live or normally dead. .-In Fig. 4 I have shown two keys near the right-hand side of the figure arranged to be normally live keys and to be dead keys in the upper case position; and I have also shown another key near the middle of the machine which is a. dead key in the lower case position and a live key in the upper case position. The last mentioned key lever has its plate 66 normally. inclined toward the observcrs right and out of the path of the screw head 65. If the case shift key be operated and all of the plates 60 be swung toward the left in Fig. 4 the two said plates at the righthand side of the figure will b moved into inoperative position and the one near the middle of the figure will be moved to operative position. The arrangement can be varied at convenience. It will also be understood that in the same machine there can be one or more keys that are dead in both case shift positions. Such a key lever would not be provided with any plate--66 but would be made aidead key in the same manner as heretofore, namely, by withdrawing the screw 24 and placing beneath said key lever one of the screws (33.

In the operation of the machine the action of the ordinary keys will be as usual heretofore. The two special key levers shown at the right-hand side of Fig. 4 are connected to type bars, each of .which has a lower case type 26 adapted to print some" nism being in normal position, the lower case character will be printed, the universal bar will be depressed, and the rocker 15,

will be operated by means of one of the cou-- I plers 66, which coupler will be depressed the screw head 65; and the operation of said rocker will work the escapenient to feed the carriage. When one of the upper case or accent types is used the shifting upward of the frame 28 and with it the wire or cam :70 willshift the coupler 66 toward the ob servers left in Fig. L out from under the screw head 65. The depression of the printing key will then result in printing the accent and in an operation of the ribbon vibrator through the instrumentality of the special universal bar 55, but the rocker 15 and the escapement mechanism will not be operated.

Fig. 4 is connected with a type bar whose lower case type 26 is an accent or other mark that does not require letter spacing and whose upper case type 26 prints some character that does require letter spacing. If

this key lever be depressed when the case shift mechanism is in normal position the universal bar 55 and the ribbon vibrator will be operated, but the escapement will not be operated, the coupler 66 being out of register with the screw head 65; but if the platen be moved to upper case position this coupler will be swung to the left underneath said screw head and a depression of this key at that time will result not only in an operation of the ribbon. vibrator but also in an operation. of the rocker 15 and of the cscapcment mechanism.

V arious changes can be made in the deout departing from my invention.
