TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 375,062, dated December 20 1887.

7 Application filed July 26,1886. Serial No. 209,162. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM O. GARNER, of Oberlin, in the county of Lorain and State of Ohio, and CHARLES F. LAGANKE, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and Improved Type-XVr-iting Machine; and we do hereby declare that the following is a full, clear, and complete description thereof.

: Our invention is an improvement in the class of type-writer in which a movable typeplate is used with a finder-arm, which is provided with a pin or projection to engage apertures or openings in an index-plate, the

index-plate and the type-plate being so constructed relatively to each other that when the pin of the finderarm engages an opening in the index-plate the corresponding letter on the type-plate is brought into the proper position to be impressed upon the paper, and has for its object increased speed in writing by printing whole words of two, three, or four letters each at one impression instead of printing them letter byletter. This is accomplished by increasing the size of the index and type plates and certain changes in the con struction to enable the type carrying or feed mechanism to be automatically changed to correspond with the change from a single letter to a word of two, three, four, or more letters.

One form of our invention is shown in the accompanying drawings, and the invention is fully set forth in the following specification and claims.

In the drawings, Figure 1 is a plan view of a Hall type-writer with our improvements attached. Fig. 2 is a section of the carriage on the dotted line 713 in Fig. 1,with the top plate turned back and shown in elevation. Fig. 3 is a front side View of the carriage. Fig. 4: is a plan view of the carriage with the top plate turned backward and shown in section. Fig. 5 is a vertical sectional View on line 00 m, Fig.

5 1. Figs. 6, 7, 8, and 9 are detail views, to which reference will be made hereinafter.

Like reference-figures are used in the draw- I ings to indicate like parts.

The main parts 01" the type-writer-the frame,

the carriage, the inking-pad, paper-holder, 5o printing-post, and finder-arm-are all substantially the same as those shown and described in the patent to Hall, No. 238,387. The typeplate is enlarged and provided with a certain number of rows of type-letters and numeralsrunning lengthwise of the machine. Next these rows of type are one or more rows of words of two letters most commonly used, such as on, to, it, is, us, as, 850. Next to these are one or more rows of 6c type of words of three letters of general use, such as and, are, the, you, Sir, 820. Next to these are one or more rows of type for words of four letters in most common use, as into, your, were, ever, thus, 85c.

The number of words may be varied according to the size of the plate and limited to such number as may be found by experience to give best results. 7c

The iudex-plate is made of a size to correspond to the type-plate, and is provided with suitable holes to receive the pointer of the finder-arm to give the proper impression of letter or word in the usual manner of a Hall type-writer.

It will be evident that as the words occupy more space than the single letters it is necessary to provide some means forgiving the carriage the proper movement in respect to the paper. We accomplish this by the following means: The feeding of the carriage is effected in the common way bya spring acting upon a pinion, a rack engaged by the pini0n,anda releasing mechanism which engages the rack and automatically releases the carriage and permits the spring to move it the requisite distance. This is accomplished by levers 29 and 31 and spring-arm 32. The two former are of the same construction as those heretofore used. The latter is, however, of slightlydifferent construction. The levers 29 and 31 are pivoted uponstud 30. Upon this stud is mounted a pinion, 34, provided with an inwardly-extending hub. This hub is provided with notches 9 5 of different depths. If the type-plate has single letters and words of two, three, and four letters each, there will be four notches in the ion 34. The racked portion is supported in engagement with the pinion by the bracket a, which is provided on top with a groove to receive the same. The forward end of the bar 35 passes through and slides in a bracket, 1), near the front of the machine. Near the front of the machine the bar 35 is provided with the upwardly-extending stud 50.

The finder-arm 38 is,as heretofore, pivoted to a fiat bar extending forward from the typeplate frame, and to this bar is rigidly attached a slotted arm, 37, extending toward bar 35, and has its slot engaging the stud 50 thereon. The slot is of a little greater length than the type and index plates, so that in moving the arm from one side of the plate to the other in a straight line the stud 50 will not come in contact with the ends of the said slot. In moving the finder-arm from one row of holes in the index-plate to another the arm 37 will move the rack and cause the pinion 34 to turn. \Vhen the pointer of thefinderarm is engaged with any of the holes in the rows for single letters and numerals, the projection 45 isopposite the notch 43 of the hub of the pinion, so that when released it will spring outward but a short distance and be arrested in such position as to engage the rack-bar 6 one groove in advance and permit the forward movement of the carriage only the space of a single let ter. \Vhen, however, the finder-arm is drawn forward and the pointer of the same made to engage one of the holes of the rows for words of two letters, the hub of the pinion is turned so that the projection 45 will be opposite notch 43, and, this notch being of double the depth of 43, on being released the spring-arm will spring outward a farther distance and be arrested in position to engage the rack-bar two grooves in advance. In like manner, when the pointer-arm is in position to print a word of three letters, the pinion is turned to bring the hub in such a position as to bring the notch 42 opposite the projection 45 of the springarm, and when the finder-arm is so placed as to print a word of four letters the pinion is placed so that notch 41 comes opposite the said projection. These notches being ofthe proper depths to permit the spring-armv to engage the rack-bar three and four grooves in advance, the required amount of movement to the carriage, when printing words of three and four letters each, is secured. The construction of without printing.

the hub of the pinion and the notches therein are best shown in Fig. 3.

\Vhen it is desired to raise the top plate of the machine, the slotted arm must be disengaged from the stud 50.

It is sometimes desired to move the carriage This is accomplished in much the same manner as in the class of typewriters referred to, only that with our construction this can be done with much greater rapidity, as by leaving the pointer of the finderarm between two of the holes for words of three or four letters a pressure upon the fingerpiece 49 will move the carriage three or four grooves of the rack-bar. The fingerpiece 49 is pivoted to the lever 29 and is held, when desired, in an operative position by a springcatch, 50. (Se'e Fig. 9.) The return of the carriage to begin another line is accomplished by grasping the thumb- pieces 51 and 52 on lcvers 29 and 31, as has been done heretofore.

The other parts not herein described are the same as those of the type-writers hereinbefore referred to.

\Vhat we claim, and desire to secure by Letters Patent, is

1. The combination, with the movable typeplate of a type-writer, having type for single letters and type for words of more than a single letter thereon, and the feeding devices, of

i a variable stop for the spring-arm of the feeding devices, and a connection, substantially as described, between said variable stop and the typeplate, whereby the movement of the spring-arm is controlled by the position of the typeplate, substantially as set forth.

2. The combination, with the movable typeplate of a type-writer, having type for single letters and type for words of more than a singleletter, of a pinion provided with stops of different lengths for the spring-arm of the feeding devices, a rack engaging said pinion, and a connection between the rack and type-plate, substantially as described.

3. The combination, with the movable type plate of a type-writer, having type for single letters and type for words of more than a single letter in rows thereon, of a pinion pro-- \VILLIAM O. GARNER. CHARLES F. LAGANKE.
