SPECIFICATION forming part of Letters Patent No. 754,366, dated March 8, 1904.

Application filed June 2, 19034. Serial No. 159,801. v(No model.)

To all whom it may concern.'

Be it known that-I, HALooLM ELLIS, a citizen of the United States, residing at Attleboro, State of Massachusetts, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification. t j.

The object of this invention is to provide a visible-writing type-bar machine of the utmost simplicity, very compact and easy to assemble, together with other features of novelty,.which will be more particularly pointed out in the description of the drawings, which are made part of the specification, in which- Figurel 1 is a vertical longitudinal section showing the type-bar action, the escapement action and a section through the carriage on line 1'1 of Fig. 4. Fig. 2 is a vertical longitudinal sectiontaken on line 2 2 of Fig. 4,

showing the shift-key mechanism and the link-A through the verticaland to the position of' forty-live` degrees to the horizontal at the A printing-point, as is clearly indicated in Fig. 3. The type-bars 1 are pivotally mounted in a segmental block 2 about a pivot-Wire 3, secured to said block 2, and' radial slots 4 within 'the block 2 serve as lateral guides forthe type-bars .1. The segmental block 2 is s upported upon an inclined face 5 of the actionframe 6. This frame 6 besides supporting the slotted segment 2 has a slotted bar I extending across the machine, which serves as a pivot-support for the key-levers 8, a suitable wire 9 forming the pivot. The key-levers `8 are of peculiar construction and are made with three arms extending radially from the pivot-wire 9, the forward arm serving for the key connection. The upper arm 8 is provided at its'upper end with a radial slot '10, which slot embraces ashouldered rivet -11 on the type-bar 1. The rear arm 8b of the keylever is shorter than either the forward arm or the upper arm and serves to-operate the universal bar 12. The universal bar 12 is the forward end of a rectangular bail 13, pivoted at 14 to the action-frame' 6, Upon the rear side of the bail 13 are fixed the stationary dog 14 of the escapement and the movable dog y15, which alternately engage the escapement-wheels 16 as the universal bar 12 i's raised or loweredl from which it will be seen that 'the escapement has a very direct connection-with the key mechanism. The forward ends of the key-levers 8 each terminate in a pivoted key-socket 17, the length of the key-lever 8 remaining constant. The key-sockets 17 are provided with suitable offsets, both forward and backward,

to accommodate the key-stems'18 of the dif-y end of itssides against the universal bar 12,

the rear end of the bail 20 being formedl by the cross-rod 21. The type-bars 1 are returned to their normal position of rest, asindicated in Fig. 1, by the springs 22, anchoredv at their' lower ends in the wire 23-and each secured at their upper ends in a small ear 24 of the type-bar y1. This ear 24 is almost parallel to the direction of the type-bar 1, so that` the spring 22 will have the least amount of extension during the first part of the movement of the type-bar 1, the tension accelerating as the type 64 approach the printingpoint. .The entire key-action and type-action so far described and also the universal bar and escapement-dogs are all mounted in the frame '6 and properly adjusted prior to be- -ing inserted in the case 25, to which they are secured by suitable studs 26. The type 6 4 before striking the paper on which they are to print pass between suitable guides 2'?,

mounted on the guide-plate28, asis usual with this class of machines.

Having described my invention, I claim- 1; The combination in a type-writer of the frame in which is mounted the key-levers and said key-levers being made with three arms,

IOO

extending radially from the pivot therefor, one arm engaging and operated by the key, another arm engaging and operating the typelevers the third arm engaging and operating the universal bar, all the arms extending radially from the pivot, type-levers mounted within said frame, springs for returning the type-levers and key-levers to their normal position, mounted in said frame, the said frame being independent of and detachable from the main frameor ease of the machine.

2. The combination in atype-writer of the frame in which is mounted the key-levers and said key-levers being made with three arms, extending radially from the pivot therefor, a

key engaging and operating one arm, another arm engaging and operating the type-levers the third arm engaging and operating the universal bar, all the arms extending radially from the pivot, type-levers mounted within said frame, springs for return-ing the typelevers and key-levers to their normal position,

4a universal bar engaged by the key-levers,

mounted in said frame, the said frame .being independent of and detachable from the main frame or case of the machine.
