To all whom it may concern:

Be it known that-I, JESSE ALEXANDER, a citizen of the United States, residing at Brooklyn,

in the county of Kings, State of New York,

have invented certain new 'and usefulImprovements in Type-VVriting-Machine Aliners, of which the following is a full, clear, `andexact description. l

My invention relates to improvements in type-writing machines, and particularly to mechanism for facilitating the adjustment and proper alinement of the type-bar mechanism. It will be found to relate more particularly to visible-writing machines in'which the type is arranged to strike a platen on an approximatelyvertical plane. The details of such a machine other than as herein set forth not beingthe subject-matter of this application are unnecessary of description herein.

The object of my invention, as will be seen on an inspection of the drawings and the description herein, is to insure t-he proper alinement of the type in the writing positionand an adjustment of the parts at this point., It 'will be found to be economical in its construction and most effective in its operation.

It consists in the improvements substantially as herein described and shown.

In the drawings, Figure 1 is a vertical projection or front elevation of a machine embodying the improvements herein set forth. Fig. 2 is an enlarged detail of what may be termed the type-bar pivot-plate and the s horizontal aline-rs. Fig. 3 is a detail; partly in crosssys section, ofthe type pivot-plate and Vaportion of a' type-bar. Fig. 4 is a viewpartly in i' cross-,section and partly in elevation, ofl affke'y and type-bar mechanism i. and the typepivotplate and aliners.

Details of construction as herein setforth' willgbe seen en inspection by one skilled in `the arttobe applieabletogmaehines of other` y typesthan-that herein, particularly described;

but for convenience 'andconciseness vthis speciffication .willbe confined to the visible-writing type of machines. .In Vthis general l class of Visible-writing machines-the platen isconstructed so as to beproperly guidedand pass position the type maybe conveniently arrangedin the are of a circle, as shown yparticularly ,in Fig. 1. 'hen the type'are ln'ought intotheir printanism, as, for example, Shown in Fig. 4, the

on the position of the platen. In order that this printinggposi'tion of the type may be uni- -form throughout the different positions of the platen, l havel provided the guide-posts or aliners A A', as `particularly shownin Fig. 2. These guide-posts are `pivoted at rl a' to what 1 term for convenience the type pivot-plate B and are adaptedzthus -to swing about the points av a. The upper end of these guide- `posts A A carry the guide wheels or disks C C', which are in their turn pvoted to the upper ends of the guide-posts Vand adapted to revolve freely about -their axes, as -will be evident on inspection of the d1'a\\'ings. In order that the positions of the guide-posts, and consequently the positions of :the guidewheels C (,l', may be adjusted as desired, l have providedthe posts A A' withprojecting arms DD', which extend to the right and left, respectively, from the posts. The outer ends cle substantially of the radius equal to the l distance from the pivots n (lf-to vthese slots e e'. `In orderto provide considerable amount of adjustment, the ends of the arms may been- -largerl\at:F-21 l'.as shown.` The set-screws or .thumb-'nuts :F.ZFfare provided, adapted to takeintothe vtype pivot-plate B and having a :shoulder to coact with the enlarged lportions lE'iE'ofithearmsD 1)' to hold the arms in uvhateverposition is desired. By these means Imay'. beinereased or diminished, as desired. 1t .will,also=benoted thathy moving the guidepostA on the right to v'the rightand theguidei post A on the left't-o the right an equal distance g each y the ispace between the guide-wheels will i 5 remain the same as before. while the open-space between the guide-wheels will have ing position by the V,key and type-bar mech.

of these arms are slotted on the arcof acir-` type is caused to strike the platen at the front thereof and at a point necessarily dependent thedistanee,between'the gmidewhcelsffb` C been shifted to the right. 'lhe same adjustment may be etl'ected in the reverse direction lo more the guide-space to the left.

'l`he construction thus tarde/scribed is adapted to be used with any suitable construction' of type-bar or type-bar pivot, the essential feature beingthat the type-bar (i shall be so constructed at a point for instance, point r/ as to pass between the faces of .the guide* 'lhus when the type- The form of type-bar pivot which is particularly adapted to be used with this form of alining device is shown in Fig. 4. The mechan ism already described provides for the horizontal alincment of the type, whilethat next to be described refers to .the vertical aline,-

ment. The type-barili, being of a suitable construction, is `pivoted at b to a lift-block H.l

This lift-block may be made, preferably, of cylindrical form and be guided'ina recess in an enlarged portion of the type pivot-plate B, the lower end of the lift-block being bifurcated to form side plates adapted to carry the pivot-pin In the top of the enlarged portion of the plate B a drilled hole is provided, in which a screw J may move freely, the lower end of Vthe screw taking into the lift-block H for the purpose of adjusting the position of the same.' Between the top of the lift-block and the under surface of the recess in the enlarged portion of the plate B may be provided a helical spring K forthe purpose of facilitating the adjustment and taking up anyfloose vplay which might otherwise occur at this (.)n an inspection of' Fig. 4it will be poi nt.

Y noted that when the type-bar isin the printing position, as shown dotted, ment depends upon the' position of the typebar pivot Il. This, as described, may be cfected by `means of thescrew JV to the extent dcsired and in a simple and convenient manner.

The Iuniversal bar of this machine may be provided, as at L, at a point rearwardof the type pi vot-plate B. The striking-face of this universal bar should for practical reasons be the vertical adjustj made o1y a depth sufiicient to allow for the desired vertical adjustment will vbe noted in Fig. 4.

The construction and detailed of' thc-key and type-bar of the type-bar, as

be found in otherapl lications filed by me, Serial Nos. 118,088, 118,084, 118,085.

'lhe type pivot-plate B is provided with a series of recesses adapted to carry the liftblocks ll, one ,for each oi' the tyjm-bars. '.lhese, as indicated in Fig. l, may be arranged substantially on the arc of a circle. '.lhe machine is preferably oi what is called a "single-shiftutype, in which aportion oi the type are on a lower case and a poi-tion on the upper case, so that each type-bar is provided with two type-faces. "By this construction it is possible to obtain m a much more compact.
