TYPE-WRITING MACHINEQ SPECIFICATION forming part of Letters Patent No. 423,576, dated March 18, 1890. Application filed September 21, 1886. Serial No. 214,147. (No model.)

To all whom it may concern.-

" Be it known that I, JACOBS W. SCHUOKERS,

j a resident of Philadelphia, in the county of "Philadelphiaand State of Pennsylvania,have

invented an Improved Type -\Vriting M achine, of which the following is a full, clear,

and exactdescription, reference being made to the accompanying drawings.

This invention relates to a new construction of the class of type-printing machines which are known as type writers and typographic machines, and has for its object to simplify the mechanism as compared with that of type -writers' and typographic machines now-in use, and to produce a perfect machine in a more economical and substantial manner than has heretofore been accomplished.

The invention consists, first, in" the use of an oscillating frame, which carries types for printing or imprinting, and which is combined with the actuating-keys in such manner that upon the depression of a key it will be moved into position to bring a certain desired type in line with the impressing lever or rod.

It also consists in combining with the devices just mentioned a peculiar mechanism for feeding the paper and in other details of improvement, which will be hereinafter more fully described.

In the accompanying drawings, Figure 1 is a plan or top view, partly in section, of a typewriter constructed according to my invention. Fig. 2 is a cross-section on the line 0 c, Fig. 1. Fig. 3 is a longitudinal section on the line k 10, Fig. 1. 'Fig. 4 is a longitudinal section on the line 0 In, Fig. 1. Fig. 5 is a detail top view showing the keys and the guide-plate for the same. Fig. 6 is a detail face view ofone of the keys. Fig. 7 is a face view of the spacing-key. Fig. 8 is a detail top view of part of the impressing lever or rod.

In the drawings, the letter A represents the case or framing of my machine. In the same is pivoted on a suitable support at a a lever B, which is more clearly shown in top View, Fig. 1, as-to its shape-that is to say, this lever has a preferably sector-shaped end on one side of the pivot a and a shank on the other. side of said pivot. The sector-shaped end of the lever B contains a grooved or slotted guideway 12, which is by preference concentric with the axis of the pivot a. This guideway 12 serves to contain and support series of types or type-blocks 0, there being as many of these types within the guideway as the machine is intended to use. That one of these types which is brought into the line 70, Fig. 1, will be the type intended for printing, because beneath that line is k will be found the impression lever or rod for crowding said type against the paper; hence the operation of the machine as far as described is to bring the types in the guideway b successively int-o alignment with the impression rod or lever and to move the impression rod or lever against the type presented to it from time to time, so as thereby to produce the desired imprint.

Each type C is held in its normal position in the guideway 12 by its own weight, or by a spring or springs 79 bearing upon or connecting with the body of said type, as indicated in Figs.3 and 4..

D is the impression lever or rod, which is adapted by means of its end f to come in line with one of the types 0 in the guideway b. The lever D is at d pivoted to the framingA.

Fig. 3 shows the lever D in its normal powhich is to be used for the moving of a type and for printing'has an inclined slot 9, which straddles the shank of the lever B, (see Fig. 2,) and which, when the keyF is'pressed from the normal position in which it is held by a spring h (see Fig. 3) into the actuating position in which it is represented in Fig. 2, causes the lever B to be swung sidewise in accordance with the extent of inclination of the slot'g.

The keys F F of the machine, by reason of their varying distances from the pivot a of the lever B and by variations in the inclinations of their slots g, will impart to the lever B varying degrees of motion, so that each key is adapted to bring one certain type into alignment withthe impression-lever. When all the keys F are untouched, as in Fig. 3, the leverBwill be entirely clear of them; hence when one is pressed that key alone will move the lever B and bring the desired typeO into alignment with the impression lever or rod D. The inner end of each key afterward presses on the lever D, as in Fig. 4, so as to cause it to push a typeagainst the paper.

The inclined slots g in several of the keys F may not only vary in degree of inclination, but also in direction of inclination, (see the dotted lines in Fig. 6,) so that the guideway b may be moved by some keys in one direction and by others in the opp JSl'EG direction,

to enable all the different types to be conveniently broughti'nto position for printing. Each of the keys F, moreover, has along its outer face an inclined edge vi, which is for the purpose of feeding the paperthat is to say, this inclined edge '5, when the key is pressed, crowds a sliding or swinging bar H from the normal position shown in Fig.1 into the position shown in Fig. 2. This sliding or swinging bar H has a pawl j, which enters the teeth of a sliding rack I and pushes that rack ahead the desired distance whenever a key is pressed. I

Keys intended to affect broad types-such asprint the letters m and w and the capital letters will be adapted to move the bar H farther than keys that affect narrower types.

.Fig. 6 shows by dotted lines at the right-hand sidehow a key for moving the bar H farther than that shown by full lines in the same figtire will be constructed. The sliding rack I has also a row of teeth which gear into a toothed wheel Z on a shaft J, so that whenever a key is pressed and the bar H moved, and with it the pawl j and rack I, intermittent rotary motionwill be imparted to the shaft J. This shaft by another gear-wheel m gears into another rack L, which carries a post M,

or a series of posts, if desired, to which the paper-carrying drum E is connected, so that whenever the rack L is moved the drum E will be. moved in the same direction and to the same extent.

It will-be seen from the special construction which is represented in the drawings that the rack I being above the wheel Z, and the rack L being below the wheel m, these two racks will move .in opposite directions; but this is a matter of convenience, and maybe modified in an operating-machine. After a key has done the work of moving the lever B, the rod H, and finally the impression-lever D,'it is let go by the operator, and will then by its spring h be moved back into its normal position, whereupon a spring 11. will slide or swing the rod H back into its normal position, the sp'rin g e carrying the lever D back to its normal position, the lever B being-carried back to its normal position, which is the position shown by full lines in Fig. 1 by the key last actuated,

as all the keys have the lower ends of their slots g in line with the shank of the lever B when that is in the normal position.

I have stated in speaking of the lever B that it has a shank. By this I mean that with reference to one row of keys F it hasa shank,

which may be entirely straight or slightly curved or bent; butit is clear that two or more rows of keys may be employed on the same machine, in which case the lever B would have a shank for every row of such The key F which is represented in Fig. 7, is the spacing-key for the machine, having only the inclined portion 2' for moving the bar H and sliding racks, but no means for mov-v ing the levers B and D, the slot q, which is in the key-box G for its reception, being at the side of the levers B and D. (See Fig. 5.)

The devices hereinabove.described can vbe used in a typographic machine, in which for the paper-carrying cylinder a matrix-carrier is substituted.
