No. 886,742. Speeification of Lettere Patent. Patentted Apr! 23, 1908.

T0 all whom it. may concem: 1 Be it known that I, MIOHAEL H. FLYNN, a oitizen of the United States of America, residing at Hartford, county ofHartford, State of Connecticut, have invented certain Improvements in Type-Writing Machines, of which the following is a specification. A

In front strike ty'p-ewriting xioaehines manufactured under the pate1its" of Edward B. Hess, the t pbars are ivoted in a segment end norm y lie towar the front of the machine. To the heel ofeach t pe bar is attached a forwardly extending link united by a vhi e ioint to the rear. end of a shorter front Whose front end rocks about a 'fixed point;

tached, the link i displaced out of parallel- 1sm With the remainder thereof. Such bend over the ends of tongue is turned around end cl'amped upon the part 4, 5, while the longer tongues are turnedaround and clamped upon those adjae ..cent parts of the link which have not been' displaced and Which are Parallel and inthe seme line ,with' .each other. When the tongues are firmly clamped, the projection 8 Will berigidly'attached to the link and cannot trn thereoh because there are two noncoincident axes 6 and 7. In this manner a rigid, stableunion of the link and projectioh mai be eifected without use of solde r end .W out objectionable use of such compression strains"as might be liable to injure the or-render it liable to breakage.

The projeotion 8 has two apertures, one 9 for connection of a'link to extend rearwardly to the universal bar of the machine and a smallerbne 10 ,for attachment of the end of a 'coiledreaction spring serving to hold the type When the joint-between these to the r1nt oint with an mcreasin veloeity. In l) m e of su ch machines v?hich have been manufactured and laced u on the market there is secured to t e link t at is attachd to the heel of the type bar a downward projection to which is ointed a rearwa.rdl extending link that o erates the universal ar. Also there isattao ed to such that acts to return thetype bar to norma position.

This invention comprises a novel means of attac hing such downward projections'to the ty)e bar operating links. n the accompsmjring drawing Figure 1 is a side elevatioh showing the ty e bar operdownward projection therefrom secured thereto in the manner contemplated 'by this invention; Fig. 2, shows a portion of sueh a link; Fig. 3, shows a sheet metal blank forming thedownward rojection; Fig. 4, a front elevation: and ig. 5, a side view showi1ig the blalnk when it has been mani ated or bent into condi tion to be applie to the link; Fig; 6, a section on the l1ne6, 6, ofvFig. 1: Fig. 7, a view of a ortion of a link towhich a projection is to e attached: and Fig. 8, shows a plate or projection applied to a link having the formation shown in Fi 7.

At one end, the link 1 is forn'oed with a snap hook 2 for efleoting a hing connection with a short front link whose front end rocks about In testimohy Whereof, I have hereunto subscribed my name.
