SPECIFICATION forming part of Reissned Letters Patent No. 11,156, dated April 14, 1891. Original No. 433,097, dated July 29, 1890. Application for reissue filed December 26, 1890. Serial No. 376,896.

To all whom may concern:

Be it known that I, JACOBS W. SonUcKnns, of Newark, in the county of Essex and State of New Jersey, have invented an Improvementin Type-Vriting Machines, of which the following is a specification.

This invention relates to that class of-typewriters in which there are keys to be de: pressed successively by the action of a finger, and these keys move frames to turn the type-- wheel a greater or less distance to bring the proper type in line for impression upon the paper, and by a continuation of the movement of the key the type is impressed upon the paper and the feed takes place'between one impression and the n'ext.-

In the drawings, Figure 1. is an elevation with the ranges of keys and the frames carrying the same removed. Fig. 2 is a sectional plan view at or near the line 5c 00, Fig. at. Fig. 3 is a vertical section through the type-wheel and paper-roll,the other parts'beingin section near the line y y, Fig. 1. Fig. 4:. is a section through the frame cariying'the keys at the line 2 a, Fig. Fig. 5 is an elevation of the type-wheel with a portion of the rear plate removed; and Fig. 6 is a rear view of the ink- The frame '13 is supported in a stationary guide-bar C, in which stationary guide-bar the.

frame is free to be moved cndwise, and there is a rod G attached at one end to the frame B and sliding through a guide it upon the bar (I, and around this rod 0 is an expansivespring that tends to move the frame 13 and p'aper'oarrying roll cndwisc whenever the latch D is lifted from the rack-teeth 5 upon the frame B. This latch D is acted upon by the mechanism hereinafter described, and

each tooth 5 is of suchsizethat the proper.

space will beallowed each movement for impressing the type, and the space between one word and another is made by lifting the latch D without impressing the type, aspaceekey being provided for that purpose. The type-wheel E is upon. an axisi -i in the frame 0 and this frameOiand the stationary guide-barf) are connectedto the bed-,

piece 0", and there are side plates 0 that rest upon the table or support and are connected at their back ends to the bed-piece O and there are tie-rods C connecting these plates C firmly together. 'lhere'are holes through these side plates 0 in which the rods F F and G G slide freely, audit-is preferable to introduce rollers 8 beneath the rods G G to lessen the friction. and cause said rods. to move endwise more easily- The rods F F are connected the rods G G are connected together by the crosswires or rods 11, so thatthese respective rods and cross-wires form two laterally-sliding frames, and one of which serves to control the feed of the paper and to give the impression of the types and the other to turn the typewheel to the proper position',as more fully described hereinafter.

Above the side plates 0 andresting upon the ledges 12 are end frames H, connected by tie-rods i3, and these end frames are grooved together by the cross wires or rods 10, and.

vertically upon their inner faces to receive 1 the ranges of frames I carrying the banks of keys. Each of these frames I is made of pairs of bars fastened together and to the end vertical bars ll, and there are vertical bars 15 between the top and bottom pairs of iongitudinal bars, so that the key-plates K can pass in between the top and bottom pairs of bars in the ranges of frames land between the bars 15, and such keys can be moved vertically with freedom, and at the upper end of each key is-afinger-piece 16, having upon it the letter or character corresponding to the letter or character upon the type-wheel that will be impressed by the action of such key, and there is a spring 17 to each kev to elevate the same, and this spring is preferably within a vertical slot in the plate form 'ing the body of the key and around a central wire or bar within such slot, the bottom of the bring the type-wheel to the proper position for the letter corresponding to the key to be impressed, as hereinafter described, and an incline-21 on one edge, that serves to feed the paper along the proper distance and togive the impression of the type against the paper.

- pressed down.

It is, however, to be understood that the space-key shown at K, Fig. 4, will not have any slot in it to move the type-wheel, but only the incline 21 to feed the paper, and as the type-wheel is restored after each movement to a position where there is not any type to be impressed there will not be any character or letter printed when the space-key K is Upon reference to Fig. 4 it will be observed that each cam-slot 20 at its lower end is directly aboveone of the cross-wires 11 of the frame G, and these cam-slots are inclined more or less either to the right or left, as illustrated in Fig. 4, and the upper ends of these cam-slots 20 are vertical. The result of thisis that the frame G is moved a greater or less distance either to the rightorto the left by the depression of any one key K, and that movement is sufficient to partially'rotate the type-wheel to the desired point,and

this is efiected by means of the frame L, that rises above the bars G and carries upon its upper surface a rack with teeth 23, that gear. into the pinion 24 upon the arbor 6 of the type-wheel, so that as the frame of bars G, cross-wires 11, frame L, and rack 23 are moved by one of the cam-slots 20 the type-wheel E will be turned the required distance to bring the proper letter into line to -be impressed.

In type-writing machines it is usual to have two sets of type, one large and the othersmall. Type-wheels of this character are well known, the types of one size occupying half of the circle and the other size occupying the other ,halfof the circle. I provide for bringing one set of types into action and throwing the other set of types out of action by moving the rackbar 23 endwise within the slot that is provided for it in the top bar of the frame L, and'with this object in View I employ a lever 26, pivoted at 27 on the'-bar'G"an-d passing through a mortise in the rack-bar 23, and at the upper end of this lever 26is ahandle and a pin 28, and at one side of the frameL is an upward projecting frame L' with two holes in it, so'that when the pin 28 is in one of the holes, as shown in Fig. 1, the rack-bar will occupy such a position that one set of type will be employed, and if the lever 26 is moved so as to carry the rack 23 endwise and rotate the pinion 24and type-wheel untilthe pin 28 passes into the holes 30 in frame L the type-wheel will have madea' half-revolution and thesec- 0nd set oftype be brought accurately in to position for use. top bar of the frame L is slotted where the lever 26 passes through the same snfliciently to allow for themovernent of the'lever 26 from one position tothe other.

The type-wheel that I prefer to use is made with a series of mortises parallel with the axis and arranged in a circle, as indicated in Fig. 5, each type being in a radial plane and guided at the outer and inner edges in I- grooves'pro vided in said type-wheel, and the body of each type 0 is made L-shaped for a spring 0' to press the type back, so that the face of the type maybe moved away from the It is to be understood that the paper, and there is an impression-lever N,

pivoted at 32 and having a slightly tapering end 33, which is immediately behind the type that is vertically above the axis of the typewheel, so that when this impression-lever is actuated the end 33 will press the type forward against the action of its spring 0 and give the impression upon the paper as such paper rests against the carrying-roll A. There is upon the back of the type-wheel E a ring 35 with segmental. openings or slots to. allow the end 33 of the impression-lever to pass through and act upon the type that may be in line with it; but this ring laps upon the V- shaped edges of the types at theirbases sufficiently to prevent them being pushed too I rod F there is a fingerSS with an inclined end that comes into contact with the incline upon the lower end of the impression-lever N, and these parts come into contact after the typewheel'has been set in its proper position and during the end movement given to such rod F and the cross-bars 10 by the keys, as next described, so as to print the letter. The inclined edges 21 of the keys K come into contact with the cross-bars 10 and move them to carry'the rods F endwise and feed the paper, as hereinafter described, and after doing so the inclined end of the finger 38 presses upon the lever N to print the letter or character, as be fore described. One of the cross-wires 10 is projected to the rear, as seen in Fig. 2, and

the end passes into the slot upon the lower "end of the camiever Rand the upper end of this cam-lever P acts upon a pin 40, that projects from the lever 41, the fulcrum of which is at 42, and there is a stud 43, Fig. 6, upon the latch D, which stud rests upon this lever 41, so that when the frame composed of the rods F and cross-wires 10 is moved byihe contact of the inclined edge 21 of either key with one of such cross-wires 10 the cam-lever P is movedaud the latch D raised to allow the spring 3 to. move the frame B and roller A endwise one tooth upon the. rack 5, and upon reference to Fig. 6 it will be seen that this latch D has two ends to it, so as to act too like a watch-escapemeut and allow only one I tooth at a time to pass by, holds the latch in its normal position, and this feed takes place before the end of the finger 38 comes into contact with the i'mpres-' sion-lever, and the upper end of. the cam-lever P being nearly an arc of a circle the latch D is not lifted beyondthe required amount and remains stationary during the impression of the type.

Upon reference to Fig. 4 it will be observed that the incline 21 on any one key commences to act against ohe of the cross-bars 1O slightly before the lower end of the cam-slot20 reaches one of the cross'bars 11'. Hence the frames composed of the rods Fand cross-bars and the rods G and cross-bars 11 are respectively moving at the same time, or nearly so, the one to bring into action the paper-feed'and the 1, draws the bars F and their cross-wires back to the normal position until the collar 51 stops. against-one of the end frames, and the crosswires 11 and rods G are restored'to their-nonmal positioninconscquence of the lower ends of the cam-slots 20 being vcrtically'in line with such wires 11; but in order to prevent the wires ll'and rods G'reoeiving an end movement accidentally, and thereby not remaining in the proper position for the keys, I make use of the detent Q, that drops into the notch in the back rod G. This detent is pivoted at 52 and is pressed down by a light spring 5-3, and at one side of the detent Q a pin projects, and there is a latch R pivoted at 54 on the back rod.'F,"and the end of-this latch is inclined at 61 to run under the pin 60 on the detent Q and lift the same, andfthe parts are to be so timed th'atincline 21 on either key gives motion to the rod F before the rods G and wires ll are acted upon sufiiciently for the latch R to lift up this detentQ and liberate the rods G and the crosswires thereof, and this latch B being pivoted at 54 its incline 61 will pass freely above the pin on the detent Q during the return movement of the parts to their uorinalpositions.

The types upon the type-wheel are to be inked in any ordinary manner. Usually it is only necessary to employ pads S upon-the plate S, that extend above the frame Cfisuch pads being at each side of the type that is pro- 1 jected when the impression is made, and these pads S being of felt or similar material, and with their surfaces in line with the faces -of the type-, th ink is spread upon such types as the type-wheel is partial y revolved, care extended straight faces,

being takefi to prevent the pads causing fricaud the spring 44 I ti'on upon the types to interfere with the movement of the type-wheel. 4

I do not limit myself to the particular typewheel represented,, as the keys, rods, crosswires, and other moving parts can be used with a type-wheelof rubber or other known type wheel or segment.

The essential feature of that part of my invention relating to the positioning movement of the type-wheel consists in the use of a slid- 'ing frame operated directly from the keys by cam action, and in claiming a sliding frame and a series of keys'engaging said frame by canrsurfaces I int-end to cover-a construction in whichthe part directly engaged by the keys has a sliding movement, as distinguished from the pivoted-frame construction long known inthe art.

By the term frame used in the claims I mean and intend to cover any construction employing a plurality of bars, rods, or their equivalents, connected so as to move together, and each engaged by keys, thus permitting the latter to be arranged in rows corresponding to the different bars, so that acompact and convenient key-board may be formed;

and the claims are not to be construed to cover a construction employing a single slidin bar, as such a construction forms-no part 0? subject-1natter of this specification;

I claim as my invention 1. The combination, with a type-wheel and impression and feeding mechanisms, of a slidthe l TOO ing frame, connections between said frame and type-wheel for positioning the latter by the movements of the frame, and 'a series of keys engaging and actuating said frame by means of cam-surfaces, substantially as described. v

3. The combination, with a type-wheel, of a sliding frame, connections between said frame and type-wheel for positioning'the latter by the movements of the frame, a series of keys engaging said frame by means of cams having whereby the frame is first actuated and then looked in position, and impression mechanism operated by the further movement of the keys after the typewhcel is positioned by the movement of the frame and while the typcwheel and frame are locked in position by the extended straight faces of the cams, substantially as described.

4. The combination, with a type-wheel and a pinion for rotating the same,of a sliding frame, a rack moving with said frame and meshing with said pinion, a series of keys ongaging said frame 'by means of cams having extended straight faces, whereby the frameis IIO , faces of the cams, substantially as described 5. The combination, with a type-wheel and paper-carrying mechanism, of the horizontally-moving frames composed of the rods F' F and cross-wires 10,.rods G G and crosswires 11 for giving motion to the type-Wheel and paper-feed, respectively, and the ranges of vertical keys having cams that act upon the respective cross-wires 10 and 11,snbstantially as set forth. 1 r

6.
