TYPEWRITER.

. Application filed December 14, 1925. Serial No. 75,822;

The invention relates to improvements in typewritingmachines of the portable type and more particularly to the type-action and its supporting frame, and the main object of the invention is to provide a visible or front strike type-action for a machine of the above character composed mainly of two' unitary parts, namely a vertically actuated approximately L shaped key-bar adapted to actuate a pivoted type-carrying bar for selectively causing one of its characters to print upon a work sheet held by a platen.

vide said type-action with an associated supporting casing or frame composed offew simple parts functioning also as the inclosing case for said machine, and which is not required to be separated therefrom during the operation of the machine' 7 A further object-is to so construct sai type-action and its supporting casing of few simple and eflicient parts thereby possibilitating the manufacture of a'more economic, durable, and lighter portable typewriter than possible with more complicated and expensive type-actions of other typewriters.

With the above and other objects in view the invention will be hereinafter more fully described with reference to the accompanying drawing forming a part of this specification, and will then be pointed out in the claims at the end of the description.

In the drawings:

Fig. 1 is a top plan view of the device embodying my invention.- I

Fig. 2 is a longitudinal side view of Fig. 1

showing more clearly the parts composing the front strike type-action and its associated supporting casing embodying my invention.

Fig. 3 is aside elevation of the supporting casing, showing same in a closed position, and r Fig. 4 is a detailed vertical side view ofthe type-bar used in said type-action.

Referring now to the parts composing the device, 1 denotes the base plate of the associated supporting casing for said type-action,

said base having sidewalls 1 and 1, a front wall 1 and an open base extension 1. A middle plate 2 having rows, of openings or slots 2-. A to plate 3 having an end collar 3 and rows 0 openings or slots 3 which are in (il'egister with that of plate 2,. as at Figs. 1

2. v Plates 2 and 3 mayifie'variously assembled on the above mentioned base 1. As shown, I provide a plurality of vertical rod supports 4 having at one or both ends threaded sockets 4, said supports linking said plates by means .of suitable openings 5, and in order to keep.

said plates in spacedpositions I provide a plurality of spacing sleeves 6 and 7, in which are inserted supports 4 between the plates, forming the easing into two interiorly spaced compartments 8 and 9, when said supports are fastened by means of screws 10, as at Figs.

a 1 and 2. It is obvious that one of the pair Another object of the inventlon is to proof spacing sleeves on each support 4 could be replaced by forming a shoulder on the support ltself if desired, as it will serve the same purpose, and that the rows of openings or slots on both the middle and top plates may be in astraight row formation instead of curved as illustrated, the idea of so illustrating said rows of slots in curved formation was to make unnecessary an angular shaping of the key-bars which will be hereinafter described, so that to add to its economic construction,.being one of the main objects of this invention.

The printing mechanism or type-action consists principally of a plurality of ap-,

proximately L shaped key-bars 11, having their vertical stem or arm vertically movable in openings 2 and 3 of plates 2 and 3, as at Figs. 1 and 2. The horizontal arm of said,

key-bars is downwardly curved at 11 and in order to return the key-bars to their normal operative position, I provide springs 12 which I prefer to insert onthe vertical arm of the key-bars and acted upon by pins 13, compressing said springs against plate 2, when the key-bars are depressed from their provided key-caps 14, as at Fig. 2. A plurality of type-bars 15, having a horizontal projection 15*, with a lon 'tudinal slot 15,

and a pivotal opening 15 elow said projec-. .tion, while between the pro ection and pivotal opening, is a forwardly disposed approximately U shaped recess 15 adapted to-receive a universal bar A, and above said projection is a folded or doubled up body part 15 forming a front-wedge 15 ada ted to actuate a' pair of longitudinally slida le bars B B, for a ribbon feed mechanism. At the uppermost end of said type-bars is a type-block 16, wh1ch may contain one or more characters mdas illustrated are indicated by- 17 and 18, as more clearly seen in Fig. 4. Said type-bars are all arranged in a curved row pivotally held spaced by a common pivot rod 19, which is curved in conformity with the row and having bearings at 20 on provided lugs of a segment 21, as at Fig. 2. Key-bars 11 are pivotally connected individually to type-bars 15, by means of headed pins 22 through the longitudinal slots or openings 15 and fastened at the furthermost horizontal end of the curved arm 11 of said key-bars, the curveon said arm serving to keep it from contacting with said segment 21 during the actuation of the keyand type-bars when one of the characters carried by the bars is caused to print upon a work sheet held by a platen C. It is obvious that some of the type-bars in proximity of their type-blocks require to be angularly shaped so that to allow each type-bar to strike a common printing point of platen C,

when actuated upon by said key-bars.

As a means for closing the open base 1 and top of said casing, when the machine is not in operation, and in order to protect its exteriorly projecting parts when the machine is wanted to be carried around, I provide a cover section 23, having upwardly bent ends or cars 23 hinged at 23 to the furthern'iost horizontal ends of said open base 1, so that if desired the sect'ion may be conveniently swung toward or from the base of said casing,

as Well as toward and from its open end to form a rear wall and right and left wall portions to said open base closing the lateral passageways of platen B, when themachine is not in operation. Asecond cover section 24, having front, right and left walls is hinged at 23 on the bent ends or cars 23 01' cover section 23, as at Figs. 1, 2, and 3. Cover section 24:, thus is also adapted to be swung toward and from the base of said casing either separately or with the first mentioned cover section, as well as adapted to cover the top of said casing to which it may be conveniently seeured'by means of a suitable lock 25, mount ed on the front wall 1 of the casing and having a cooperating part 25 mounted on the front wall of said cover section 24, as at Fig. 1. A handle 26, may be mounted on the front wall 1 of the casing for convenience in carrying the machine around.

The above described type-action operates as follows:

At the depression of a key-bar 11, from its cap 14,;a type-bar 15, moves toward printingposition, the horizontal projection 15 of this bardepresses universal bar A, for escapement operation, and before thetype-bar strikes the printing point, universal bar A,

returns to normal position by entering recess l5 uofthe bar; in the same instant, wedgelS of the type-bars entering inlet D, which is formed by the bentends of slidable bars B B, the latter being in a movable coacting position, causes the slidable bars to move longitudinally in opposite directions, thereby actuating a ribbon feed mechanism, whenthe type-bar retreats from printingposition, the

longitudinally slid-able bars return to'their normal positions.

In the foregoing description, I have embodicdthe preferred form of my invention, but I do not wish to be understood as limiting myself thereto as I am aware that modification may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope of the claims.
