TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent 110,365,373, dated June 28, 1887.

' To whom it may concern..-

Be it known that I, ALEXANDER G. DoN- NELLY, of New York, in the county of New York and State of New York, have invented drawings, is a specification.

My invention relates to type-writing machines, and is an improvement upon the inventions described in the application No. 145,749, filed by me October 17, 1884:, and in another application of even date herewith; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of thedrawings and to the claim to be hereinafter given.

Figure 1 of the drawings is a plan of the pivoted head of a machine illustrating my invention, the bed, the paper-carrying roll, its carriages, and the mechanism for operating said carriages and roll being omitted, and a portion of the outer casing being broken away to show parts beneath; and Fig. 2 is a vertical transverse section of the complete machine, except that only three type-hammers and three k eys,one for each bank,are shown,the cuttingplane being on line 00 a: on Fig. 1.

In the drawings, A is the bed; B and O,the lower and upper carriages; D, the paper-carrying'roll, all constructed, arranged, and operated in the same manner as described in my last-cited application, and as they form no part of my presentinvention, they need not be further described here.

E is the main casing of the head ofthe machine,pivoted to the goose-neck-like stands F F, and locked thereto precisely as described in my first-cited application.

G Garethe type-bars mountedin the sleeves G, and having secured to their outer ends the pinions (0,120 engage with and be operated by the ring-gear H, and provided with radiating grooves to engage with the guide ribs or lips I), all constructed,arranged, and operatingsubstantially inthe same manner as described in my application of even date before referred to.

In both of my'other applications the operating-keys were arranged in a single circle above the casing of the head, through which their stems passed directly to and were secured by their lower ends to the type-bars. This arrangement of the operating-keys being a departure fromthe common practice, involving considerable trouble to the operators in learning the new arrangement and unlearning the old, I have thought it very desirable to arrange the operatingkeys in front of the head in a series of banks; and to this end I reverse the letter and space feed operating spindle I-that is, I mount it in a bearing in the center ofthe main casing, but with its flange 1 above said casing,instead of below it, as in my other ap- 'plications-and mount aseries of key-levers, J, on pivotal bearings supported by said main casing, some of them being hung in ears 0 0, cast directly upon said casing, and others in cars pendent from the stand (I, secured to said casing, as shown. A portion of these keylevers extend over the flange I of the spindle I and have their rear ends bent downward and forward beneath said fiange,while the others extend directly under said flange, their rear end portions being bent sidewise in one or the other direction to a greater or less angle in such a manner that that portion of each lever which extends under the flange I shall be substantially radial to the axis of the spindle I, as shown in Fig. 1. V

K K are two space-key levers, also pivoted to cars projecting upward from the casing E, and engaging with the underside of theflange I, for the purpose of operating said spindle independently of the movements of the keys J, two keys K being provided, so that the space-feed may be operated by either hand of the operator. Each leverJ is connected by the link d with the inner end of the lever L, pivoted at e,and connected at its other end to the upper end of the link f, the lower end of which is forked and pivoted to the sleeve G, as shown in Fig. 2.

The spindle I hasa bearing in the hub E, projecting downward from the casing E, and projects below the lower end of said hub, and is provided at its lower end with the screw head g, between which and the lower end of said hub the spring h surrounds said spindle, and serves to move said spindle downward after it has been raised by either of the keys J or K,iu an obvious manner. The spindle I is also provided with a slot, 1?, to receive the inner end of the lever M, the hub E being slotted to permit said lever to reach the spindle I. The lever M is pivoted to cars j,castupon or secured to the under side of the easing E,and passes through a slot in the casing E,and also through a corresponding slot in the outer casing or cover,N,and has its lower end forked to engage with the carriage-operating mechanism when the casing E is in its normal position and enable it to be readily disengaged therefrom when the casing E is tilted backward upon its pivots E 0 is a lever, secured at its rear end to the ring-gear H through a slot in the basering of the casing E, as shown and described in my other application of even date herewith, said lever projecting beneath the keys J to apoint 111 front of the front row of key-buttons J, so as to be conveniently accessible to the operator, and so that it can be readily moved in either direction by either hand of the operator by pressing upon the button 0'.

N is the outer casing or cover fitted closely lo the vertical wall of the main or inner easing, E, for about three-fourths otthe circumference thereof, its front portion being extended outward to inclose the upright portions of the key-]evers, as shown.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is

The combination,in atype-writing machine, of a pivoted head or casing, a series of typebars, and a corresponding series oflevers,each connected at one end toone of said type-bars and all arranged radially within said casing, a flanged spindle mounted in a bearing in the center of the main casing of said head, with its flanged end uppermost, a series of keylevers pivoted to supports upon the exteriorof said casing and provided at their frontends with finger pads or buttons arranged in a plurality of rows or banksin front of said casing, and each connected in the rear of its fulcrum with one of said radially arranged levers within the easing,and having its rear portion extended beneath the flange of said spindle in position to act thereon to raise said spindle when the finger-pad is depressed, anda single lever connected with the inner portion of said spindle by one end and having its other end forked to engage with the carriage-operatin g mechanism mounted upon the bed, substantially as described.

In testimony whereoflhavc signed my name to this specification in the presence of two subscribing witnesses on this 16th day of November, A. D. 1885.
