TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 685,7 2, dated November 1901- Application filed January 13, 1899. Serial No. 702,054. (No model.)

To all whom it may concern:

Be it known that I, FREDERIC W. HIL- LARD, a resident of Tottenville, county of Richmond, and city and State of New York, have invented certain new and useful Improvements in Type-Writers, of which the following is a specification.

My invention is an improvement in typewriting machines, which relates to a simple and efficient means for shifting the typeheads upon the type-bars in order to eifect the printing of a plurality of type with the same typebar. This improvement is designed more especially for use on machines adapted for writing on bound books. On such machines the paper is placed upon a fiat platen or printing-surface in contradistinction to the cylindrical platen of the ordinary commercial-letter writer. The invention is, however, adapted to machines whether the platen is provided with a flat printing-surface or a curved one.

Myinvention also comprises the various details of construction herein shown and described.

In the accompanying drawings, which form a part of this specification, Figure l is a sectional side elevation of the machine, showing some of the typo-bars and type-heads and the mechanism for shifting the type-heads on the type-bars from one printing-base to another. Fig. 2 is a detail of a type-head of Fig. 1. Fig. 3 shows a modified type-bar with its typehead and several other parts which are operatively connected therewith. Fig. 4 is a detail of the type-head of Fig. 3. Fig. 5 is a sectional detail of a portion of the type-bar and of the pivot of Fig. 3. Fig. 6 isa side View of the parts shown in Fig. 5.

The carriage A is mounted for lateral. movement upon frame 13 and is supported thereon by rollers W W at the front and at the rear, which rest upon guide rails g g, fixed to frame B. The type bars T are pivotally mounted on hangers T, so that they can be moved from the buffer-ring b to the platen for printing. The hangers T are arranged concentrically around the circular opening in the carriage A, so that the type will all print at a common center. I have only shown two of the type-bars, one at the front and one at the rear of the machine; but I wish to have it understood that there is a circular opening in the carriage and that the type-bars extend entirely around this circle. The type-heads H are pivotally connected to the type-bars by the type-head screws 0. Each type-head comprises two type, an upper-case type u and a lower-case type Z. Both of these type are formed integral with the type-head, and each of them is provided with a shank u and Z, respectively, which connect them with the main body of the type-head. Some of the functions of these shanks u and Z are to correct any imperfection in the positioning of the two type it and Z relatively to one another upon the type-heads. The shanks are so made that they can be bent and twisted so as to establish the proper distance between the two type, and they can be cut with pliers in order to throw the type upon their feetthat is to say, to cause it to strike the paper evenly.

The type-heads are controlled in both printing positions on the type-bars by means of type-head spring S, the type-head being provided with a tapered projectione and the typehead spring being provided with a mounted indentation j for engagement therewith. The projection t' and the indentationj are so positioned relatively one to the other that the point of the projection i shifts across the point of indentation y when the type-head is shifted from one printing position to another, and the inclined faces on both sides of the indentationj upon spring S engage with the corresponding inclined faces on the sides of the projection i to control the type-head on the type-barin each printing position. The typeheads are each provided with the bankingfaces m and n, and each type-bar is provided with corresponding banking-stops m and n,

which engage with the banking-faces m and n and positively limit the throw of the typeheads upon the typ-bars in either direction.

The method in which I construct the modified type-bar T of Fig. 3 is as follows: I first punch the bar out of sheet metal. Then I force the metal comprising the banking-stops m and it out of the body of the type-bar, forcing this metal half-way through, so that it may comprise the banking-stops m and n, but only partially through, so it still remains IOO an integral part of the type-bar. I then punch a hole through the pivotal portion of the type-bar and a hole through the lower extremity of the bar to receive one end of the wire connecting the type-bar withthe corresponding key-lever. Through the pivotal hole I insert a short piece of wire and rivet this wire on each side of the hole. This forms the body d, of sufficient thickness to securely hold pivot s of the type-bar. The type-bars are connected with the key-1e vers V by means of the connecting-wires o o, and at the opposite end of the key-levers the finger-keys K K are provided in the usual manner. The typebars are normally held in a perpendicular position, with the type-heads resting in buffer b, by means of key-lever springs V V.

The operation of my type-bars and typeheads is as follows: Mechanism is provided for shifting the type-heads from the lowercase position to the upper-case position on type-bars, which I will now describe. Shiftkey lever R is connected by means of shiftkey-connecting wire L tothe rocker-shaft arm 'M, which is rigidly fastened to one end of the rocker-shaft N. To the opposite end of the rocker-shaft N the rocker-shaft arm 0 is rigidly fastened and operatively connected by a pin (not shown) with disk plunger-rod P. The disk plunger-rod is normally held in a raised position by means of shift-spring Q,

thereby holding the tripper-disk D normally in the raisedposition shown in dotted line in Fig. 1. Fig. 1 shows the parts of the machine with shift-key lever R depressed and the disk D lowered into operative position to effect the shifting of the type-head from the'lower-case printing position to the upper-case printing position. The tripping end CtiS of such length from the pivotal center of the type-head that when engaged by disk D upon the depression of shift-keylever B it will force the typehead to be swung on its pivot far enough for the point of the projection 'i to move across the point of indentation j. After the typehead has been swung thus far the pressure of the spring S against the upper inclined face of the projection 'i will complete the movement of the type-head until the banking-face m engages the banking-stop m, which limits the movement of the type-head on the typebar. When the type-bar is in position for printing with the upper-case type, the'tripping end a swings :with the type-bar free of disk D. Therefore when the type-head is in the upper-case printing position upon the re-' lease of the type-key. K the type-bar will swing up past disk D until the type-head engages with bufier b, and then the pressure of the tripping end a against buffer 1) shifts the type-head back tolower-case printingposition,

with the banking-face n in engagement with banking-stop n. When the shift-key lever B and the tripper-disk D are in their raised positions, the type-heads are not shifted on the type-bar when the printing-keys K K are operated. Thetype-heads remainatalltimes while in the buffer 1) in the lower-case print? 1 ing position; but when the shift-key leverR is depressed, together with disk'D, each typehead will be shifted by contact of trippingjend a with disk D from lower-case printing 2; position to upper-case printing position dur-i ing the depression of the printing-key, and"? Y i will then be returned to lower-casc-printing; position upon the release of the key by con-,

tact of tripper end a. with bufier 'b.

I do not in this application make any claim to the above-described tripping and control- 0? ling mechanism for the type-head except in their combination with the integral type-head 1' herein described, as such tripping and controlling mechanism form the subject-matter;

of and are claimed in my application filed May 25, 1897, serially numbered 638,007,111-

August 4, 1900, Serial No. 25,928.
