useful Improvements in Pointer Attachments` I for Type-Writers, of which the following is a specification. y

My invention relates to pointerattachments for type-writers, more especially adapted to the Remington pattern, said attachment device consisting of a base-plate having two parallel legs with slotted feet adapted to screws normally in the machine, the said legs,

being tied by a cross-bar and terminating 1n projecting heads, into which are'itted inwardly-converging conically-pointed screws engaging and carrying a rocker-shaft having secured thereto (laterally) a curved tube adapted to receive a pointer extension-'rod carrying a cross-head, to which is hinged a knuckle-jointed extension-plate 1, having hinged to its opposite end a second extensionplate, to which is hinged a pointer-support- V.ing sleeve, in which is a pointer-supporting rod, being maintained in position by duplicate stay-bars secured to the carriage-supporting pivot-shaft of the machine. To the upper portion of the said sleeve is hinged a pointer finger or index having its extreme end pressed a ainst the laten or paper by means of a spira spring, t e said finger-point being adapted to the right or left adjustment to secure alinement with the type impression on the pa er by means of the aforementioned conicaliiy-pointed screws. To facilitate the downward and backward recedin of the pointer extension-rod and cross-hea a spiral spring is attached thereto and to the guidetube, all of which will hereinafter be more fully explained.

The objects of my invention are, first, to provide an accurate and reliable pointer or index attachment for the Remington and like type-writers second, one easily and quickly attached and without extra screws or bolts; third, one adapted to right-and-left adjustment fourth, to operate freely without interfering with other working parts of the type-writer. I attain these objects by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which- Figurel is a front elevation of thelprincipal upper portion of a Remington typewriter with its carriage elevated in the position for reading the writing, detection andv correction of errors, and showing my pointer device attached and in its extended position,

non-essential and obscuring portions of the4 machine being removed. Fig. 2 is a plan view of a portion of the top of the type-writer with my pointer device attached thereto and in the position assumed when the carriage is lowered to its working position, all obscuring parts being removed. Fig. 3 is a transverse section of Fig, l on the line of my. Fig. 4 is' an edge view in elevation of one of the uplicate stay-bars. Fig. 5 illustrates the relative position of the parts and the platenv of Fig. 3 above the line 'y z when the carriage is lowered to the writing osition.

Similar letters and ures refer to similar parts in the several views.

In the drawings, A is the carriage-supporting frame of a Remington "type-writer. A- A are the front 'corner-posts. C is the rack. D is the carriage-track. E is the frame-support of the carriage ivot-shaft F. G is the platen. J is the sca e, and B is a portion of the rear top plate of the machine, to which the slotted feet of the base-plate legs 1 1 are secured by the machine-screws 2 2. The head projections 3 3 of the said base-plate legs have fittedv therein laterally conically pointed adjusting-screws 5 5, adapted to en- 1gage, adjust, and support the rocker-shaft 6,

avin secured thereto (transversely) the curve guide-tube 9 ,into which rod 9 is ada ted to shde, the pointer-supporting rod 8 eing maintained in position by its ends being secured in the upper ends of the duplicate i stay-bars 8 8, having their lower ends securely'but adjustably attached to the carnage-supporting pivot-shaft F. To the upper portion of the said sleeve 3 is hinged the pointer-finger 4, the extreme end being normally in contact with the platen G or the paper thereon by means of the spiral spring 4 and having an angle and a curvature adapted to the periphery of the platen G and the face of the scale J, as illustrated in Fig. 3.

For the purpose of forcing and retaining the cross-head O in proximity to the rock'` shaft 6 when the carriage is lowered writing position a spiral spring .0

The adjusting-screws 5 are for the purpose of securing eXact vertical alinei'nent with the type impression on the paper and theextremity of the pointer-finger 4. This is obtained by a right or left movement of the rocker-shaft 6 by means of the said adjustingscrews 5 5, the purpose of said pointer-finger being to indicate the exact location of the type-letter impression upon the platen or the paper thereon. y

To attach my pointer device to the machine, irst raise or elevate the carriage, loosen the two screws 2 2', slip the slotted feet of the base-plate into place, and turn the screws down; second, place the stay-bars 8 8 the rocker-shaft to the rig t or left until the in position on the pivotshaft l." loosely; third, extend the pointer-supportingl rod 8 through the sleeve 3 and the upper ends of the said stay-bars and tighten the screws, securing the said rod irrnly in its proper position, and by means of the screws secure firmly the lower ends of the said stay-bars; fourth,

by means of the adjustin -screWs 5 5 move oint of the pointer-finger is immediately eneath the center of the -type impression on ,the platen or the paper.

In operation the carriage is raised or ele- `vated to the reading position, as in Flg. 1.

If a wrong letter in a word should be discovered, erase the lett'er and move the carriage.

Y- or rotate lthe platen until the place of the erased letter-is immediately over the point of the pointer-finger, lower the carriage, and

strike the proper key or letter button to produce the desired letter or type impression on the paper.

In the present case for purposes of illus trating my device a Remington type-writer is used, though my pointer attachment isl equally well adapted to other similar machines.

Having thus described my invention,what

I claim, and desire to secure by Letters Patent, is-

1. In a typewriter, and in combination therewith, a pointer attachment, comprising a base-plate, having parallel legs, with slotted feet, headV rojections, adjusting-screws, a cross-bar ang rockerfshaft, and a curved guide-tube, a guide-rod having a cross-head,

a curved pointer-nger, and a spiral spring connectin the ide-tube and cross-head,

substantially as escribed.

2. In a pointer attachment for-type-writers, the combination with the pointer-finger Vof a curved guide-tube and guide-rod and means for operating the same, substantiallyA as described.v

3. In a ointerattachment for type-wri ters the combination 'with the base-plate having
