' Application fildhovfixher 8. 199-7. satin No. 657,237. (No modh) To all zohom it incl/1] cmfwefz'tr I I Heft n w h t'w -tWI LfI i R- F GliE'NN J.,BARRETT, cifti'zens' of the United- States,residin g at GrandjR'ap ids,Kent county, Michigan, have in'vented'c'ertainnew and useful Improvements in" Electrically- Operated Type-Writers,of which the following is speci-' et m, A I

Our invention relates to electrically-operated type-writers; and the object thereof is' to provide a machine of the well-known basket type in which a device cornmon to an the type-bars and electrically" actuated i's'provided for operating the type-bar's to make the impressions, mechanical" means hein'gern ployed to act in advance of said device tode terrnine the type-hart to heoperated thereby.

The intention relatesalso to certai'nf,details at construction, as" will he hereinafter described, and particularly pointed out in the claims. I

The machine is illustrated in. the 'accornpanying drawings, in which I Figured is'a side elevation, parts being in section, showing qn a single type and typebar and its operating connections. Fig. 2 i sfa plan View thereof. 4 Fig. arse detail'fro n't eleration eta-portion of the machine. Figs. 4, 5, and 6 are detail iews.

The frame 11 of the machine may be of any construction having atop plate with a ceritral opening and the type -l)ars' disposed around thesame i'n hask'et forln, although we prefer to: follow 'th'e general line of the inachine firming; the subject of apr'ior applica-' tion, Serial No. 609,332, filed OctobeTIQ, I896.

The top plate 10 of the machine herein shown is provided with a central opening, aronnd the edgeof which a series of hangers 4'5 are arranged, in which the type-bar's tears pivoted. These type-bars 4'4 are of ordinary bell -crankfo'rr'n, having their longer menihers depending within the opening and carrying the type and their shorter members pirotally secured todependinglinks' 46. In the pres ent case but a single type-bar audits connection are shown, this heing' deemed sufficient forthe purpose of illustration. A series of brac kets'm are secured tothe under to" support the buffer-ring 1"3, which inloses is" su ported.

the'lower parts of the type-bar in their inactive' position, and from this ring a'fra rnle 1a This frame 14: is made of a flat metal strip having a h'orizontally-extending bottom portion and vertical sides which are secured to the'buffer-ring 13 at opposite points,

clearly shown in Fig. 3.

K cross-bar 16, bolted at each of its ends, which are upturned, to the vertical sides of the frame 1e, hasja central guiding-opening therein, whichis in vertical alinement with a corresponding opening in thehorizontal portion of the frame 14, and through these openings a vertically 7 reciprocating rod 15 is cit tends above and across the end of said rod and carrie'sa cone-screw 18, provided with a .locking nuftjfor limiting the upward moveinenftof said rod, as will be hereinafterjde-f scribed, a stop 5lbein'g adjustably" sec d ;to the rod between the bar 16 and the;

zontal portion of the frame to limit the dew. I ward movement of the rod. To recip ate the me, one arm 21 of a bell-crank leyer 21 is pivotally secured to the bifurcated en-dot the rod 15, the opposite army of said lever carrying a soft-iron armature 31, which isadapted to be attracted by the magnet 30 when energized. One magnet or a plurality of magnets may caused, in the present case two being shown, which are arranged centrallyofth'e machine at the rear thereof. -Any kind of a keyboard may be employed,

and the keys 89 have their stems 39secured in" horizontal members 0E L'Shaped clips which have their vertical members bent around to rigidly secure the same to rockshafts 33, journaled at their rearends in bracket 32, extending across the machine and at their forward ends in a vertical depending extension all of the front plate of the'inachine. in their normal position, springs 50, each havbig one of its ends secured in the extension 41', are coiled thereabout and secured thereto. It will he understood that there is a rocking shaft for each key, including the spacing-key. Extending entirely across the gfr'ontfof the machine, beneath the ends of the ey-St frame, but secured to the sidesthereof, and

is ajplate37, insulated from the To hold these rocking shaftsv guid'ed. A bracket 17, secured to the bar 16,.

above this platc is a corresponding plate 40,-

having openings therein to guide the keystems. The current when the circuit about to be described is completed enters the magnets to energize the same through the wire 34, secured at one end to the binding-post 28 at one side of the machine near the rear thereof. This wire runs from the bindingpost to the magnets and from thence to one end of the plate 37. A return-wire leads from the opposite end of the plate 40 t0 the binding-post 27, secured adjacent to the post 225 in the side of the machine. On the depression of a key the end of the stem thereof will contact with the plate 37 and close the circuit, when the magnets will be energized and the rod 15 drawn downwardly by the bell-crank 21". To the under side of the cross-bar 16 a circular disk 20 is secured, which has its edge provided with a series of tongues formed by recessing said edge, the

ends of said tongues being coiled about a wire rod 49, which forms a pivot common to all of a series of bell-crank levers 25, which are held in said recesses. I

A lever 25 is provided for each key, with the exception of the spacing-key, and said levers are arranged in the same radial position as the type-bars 45, one for each bar. The shorter members of said levers are each pivotally connected at their ends to a link 42, having its end held in an angular clip 36, corresponding to the clips 38, so that on the rocking of the shaft 33 the shorter member of the lever 25 will be pulled downwardly and throw its longer member 25 inwardly and upwardly similarly to the movement of the bar 44. V

The end of each of the members 25 is forked to provide a seat for a flat plate 43, havinga recess in the front edge thereof to provide a shoulder 43. A link pivotally connected to the shorter mem berof each type-bar depends therefrom and has its end fixed and rigidly held within the socket in the end of each of the plates 43.

To the rod 15 a flat circular disk 26 is secured by means of collars 19, secured to said rod, which clamp said disk between their adjacent faces. The outer edge of this disk is turned down to form a flange to increase the rigidity of the same and to provide an edge to engage the shoulder 43' of each plate 43. In the inactive position of the parts the plates 43 surround the disk 20 at a slight distance therefrom with the shoulders 43 below the edge of said flange. 0n the depression of a key, provided it be not the spacing-key, the rocking shaft will turn and draw down on the corresponding links 42 through the connections before described. This will tilt the lever 25 and push the shoulder portion of the plate 43 beneath and in the path of the flange of the disk 20. The circuit being closed by the stem contacting with the plate 37, on the continued depression of the key the rod, as before described, will be drawn downwardly,

causing the flange on the disk 26 to engage the shoulder on the plate 43, which will draw down on the link 46 and lift the type-bar to make the impression. After the release of the key the plate 43 is quickly returned by a coiled spring 47, which extends from each of the plates to the under side of the top plate 10, the type-bar of its own weight also tending to drop back when released. The under side of the member 21 of the lever 21' is provided with depending ears spaced a slight distance apart, through which the bar 23 passes, which is connected by a link With spacing mechanism, (not shown,) so that on every movement of the armature and lever carrying the same the carriage will be fed forward one step, and by means of the spring I which returns the feed-rack the lever 21 will be assisted in its return on the denergizing of the magnets. When the spacing key IS operated, the magnet will be energized and the rod 15 depressed; but as all of the plates 43 are out of the path of the disk no'operation of the type or type-bars will take place. By operating all the type-bars from a common device the evenness of the impression is insured.

We claim I 1. In combination, the type, type-bars, and links, the keys, the plurality of rock-shafts horizontally arranged, one for each key, the pivoted bell-crank levers, a connection be tween each rock-shaft and one of said bellcrank levers to operate the same to position one of the links on the depression of a key, and an electrically-operated device to actuate the positioned links, substantially as described.
