To all whom 2'23 may concern:

Be it known that I, ALvArI C. Ronnnon, a citizen of the United States, residing at Wooclstock, in the county of lvlcllenry and State of Illinois, have invented certain new and useful Improvements in Type-Wifriters, of which the following is a specification.

This invention relates to typewriters, and more particularly to the form and construction of the frame, together with the general construction, location, arrangement and method of assembling of the various parts on the frame, and the principal object of the invention is to provide machine of this class in which the several parts may be as semblecl on the parts of the frame with the greatest facility and economy of time anti a consequent reduction in cost of assembling of the machine as a whole.

A further object of the invention is to provide a machine of the class described in which certain of the parts may be assembled on one or more parts of the frame and other parts on other parts of tne frame independently of each other, and the several parts of the frame, together with the parts as selnbled thereon, may be easily and quickly assembled to form a complete machine.

For the attainment of these ends and the accomplishment of other new and useful-objects, as will appear, the invention consists in the features of novelty in construction, combination and arrangement of the several. parts generally shown in the accompanying drawings and described in the specification, but more particularly pointed out in the appended claims.

In the drawings, Figure 1 is perspective view of a typewriter constructed in accordance with the principles of my invention and comprising a top plate and member of the typewriter but omitting the carriage and certain other parts; Fig. 2 is a view in perspective of the base member together with certain parts assembled thereon; Fig. 3 is a view in perspective of the top plate of a frame in an inverted position with certain of the elements of the typewriter assembled thereon; and Fig. i is a side elevation the machine illustrated in l A typewriter consists oi a number. of different parts, all of which must be as semblecl, lit accurately and cooperate with other part Many of the elements are simiof the frame, while the top plate is in posh lar and all, or nearly all of the separate parts are in themselves quite inexpensive, particularly when rnacle in a considerable quantity. In fact, many of he parts are constructed of sheet material, but and formed in particular shapes of the conformation. One of the greatest e penses, therefore, in. the production of a gewriter or other machine of this is expose of assembling the various parts and in pa, ing them in the proper cooperative icla tionship with respect to each other in machines o: is class it is customary to semhl': a great many of the parts with top plate in p siticn on the frame in l 1 in fact, many 0' the frames are made of a sectional con l"c"ion. to'it'acili: tate the assembling of the parts.

' In this construction, however, t1 rlili'l a simple two-piece frame consisting of base member 5 and a top plate ii. The ma chine is assembled by inverting the top plate 'culties are entirely eliminated; by providing and securing to it the several elements which tion on the base member. They can all he readily seen and conveniently plaoetl in their proper position in both of the frame inemhers, and then after the parts are in their proper places on both the base member and top plate of the frame, the top plate inverted and placed iii-position. upon the upward extensions of the member and the several connections are inane between the several parts either before or after the top plate is secured. in proper posi .on ripen the base member.

Referring more particularly to the drawings, the base, member 5 is preferably con.

structetl with upward extensions or posts '3 at the corners by means otwhich the top plate 18 supported anal to which. it is secnrecl by suitable fastening means 9 A front en.

tension 10.01? the frame forms a guard for the keyboard, and .a cross-piece ll cons-ti tutes a guide for the key-levers,

Mounted in the base member of the frame are type-bar key-leyers 1S; spacing mechanism comprising a space bar 13 and; a link 13 carriage shift mechanism comprising carriage shift-lie *s 14 and a shift-arm 14 carriage shift-key locking mechanism. 15; a tabulator key 16 with a link 16; a line lock key 17 Witl'i a link 17; and a back-spacer y 17' with an arm 17.

The top plate 6 comprises a, yoke 18 at the forward edge which preferably rests upon the cross-piece 11, and a lateral de- ;pression 19 at each. side to permit the free passage of the carriage and carriage shift rail (the former not shown). surface of the yoke 18 preferably forms a rest for type-barsQO pivoted in a type segment 21 secured to the top plate 6,

Mounted on or secured to the top plate 6 are many of the Working devices of the machine; the central portion is cut away and forms a space for the free movementof the type-bars. Among the other devices mounted upon the top plate are; the universal. bar comprising a reciprocable frame mounted. in a rocker a ribbon Vibrator 24: with an adjusting device 25 at the forward. edge of the plate having {JOIlllBCtlOIL with the v1- 1 p -h 11 t -D1 1t01 -01 .aryiu m, ..V pat 0i e ype Writer ribbons contained no ribbon 5 3001926 on the upper side of the plate; tabula'or mechanism designated generally by the ref.

erence numeral 2! and comprising a link' 28; ribbon. re erse and feed mechanism comprising a shaft 30, pawls 31 and toothed Wheels e back-spacer mechanism designated generally loy'the reference numeral and. comprising lever 34.; carriage shift mechanism comprising; a pivoted shaft and an end plate foaming an abutment 36- secured thereto; line-lock mechanism comprising a link 4-1 and signal bell 38, and a carriage motor 39 comprising a thumb-- screw 40 for tightening the spring of the motor.

When the various or elements of the operating mechanism of the machine are assembled upon their respective parts of the ironic, that is upon the top plate or -member of the frame, the top plate is inverted and placed in position on the posts 7 of the base frame member 5. "With the top plate in this position the cooperating parts on both of the frame members are in such position that they may be readil and easily connected; the slziftn. M? bears against the a utneht 34?; the tabulator rear end of the key lever 16; the lin release arm 1? a is conto thel'i-ie-locar release lever 4-1; the backspacerla connected by means as of a link. 32 to The upper the letter space lever is connected by means of the arm with a bracket on'the universai bar frame 2-2.

in assembling, the type-bar segment 21 IS F 3, and after the top plate has been attached to the base member, the type-bars 20 are connected to thelr corresponding keylevers l2 and pivotally mounted. in the segment :21 in any Well known manner, as by. means of a pivot Wire 4:3.

From this description it will be seen that the parts are readily assembled both upon the base member and upon the top plate member in inverted position, and after the parts are all secured in position upon their respective supporting frame part, the top plate is turned u ight, the two frame parts are secured together, and it is necessary only to make a comparatively few connections to place the machine in operation. The as sembling is all done with the frame membore in their most advantageous position so that all the p. ts are easily accessible.

It is to be lerstood that although not all of the parts or a typewriter named in the description as being assembled upon one part or the other of the frame, enough of them have been named to Show the prin ciple of the invention and the advantage to be gained from this construction whereby several of the parts of a mechanism are sembled on one frame element and coopen atinp; parts on another frame element and the two cooperating parts on the separate frame elements are joined when the frame parts are placed in proper position with re spect to each other, It to be understood, of course, that parts not specifically described in the specification are or may be connected to the frame. lln general, it may be said the operating parts are located on one of the frame elements and the act sting parts on the other frame element, the connection of the corresponding operating and actuating parts completing the device as a Whole.

This invention is independent o i specific forms of the several devices which compose the typevl riter, and it is immaterial, therefore, justl What construction is can ployed. An operative construction is shown possible, of course, to vary this construction, Without departing from the spirit and scope of the invention. example, a built up frame, that is, one in which several. frame parts are assembled separately to form two piece frame may have the operating and actuating parts separately assemlilled on the respective frame parts.

I. in typewriter, the combination With a compr' member and :1:

plate member ace attached to the top plate, shown in memes ed to be secured thereto, of typewriter operating mechanism adapted to be mounted on and secured to the under side of the top plate member and to be assembled thereon when the top plate is independently inverted, actuating means for the operating parts separately mounted and assembled in the base member, and means to connect the corresponding operating and actuating parts, the top plate being inverted and placed in position on the base member after the operating parts are assembled.

' 2. In a typewriter, the combination With a frame comprising .a base member and an independent top plate member, of a type-bar segment, type bar key levers mounted in the base member, type-bars connected to the key levers and pivotally mounted in the type-bar segment, operating mechanism independently mounted on and supported by the top plate, actuating mechanism for said operating devices independently mount ed in the base member, means for connecting the corresponding operating and actuating parts when the top plate is placed in position on the base member, and means for inseparate actuating devices for each of said mechanisms mounted in the base member,

and means for connecting the cooperating mechanisms and devices when the top plate is placed in position on the base member.

In testimony whereof I have signed my name to this specification, in the presence of two'subscribing witnesses, on this 21st day of April A. D. 1914:.
