TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patentll'o. 380,792, dated April l0, 18881.

Application tiled June 1, 1886. Serial No. 203,880. (No model.) Patented in England May 24, 1886, No. 6,935; in France August 5, 1886, No. 177,787; in Germany August 13, 1886, No. 39,044, and in Austria-Hungary November 7, 1886, No. 47,566

and No.11,812.

To a@ whom, it may concern.-

Be it known that I, ADOLPHE PRosrER EG- GIs, of Fribourg, in Switzerland, have invented a new and useful Improvement in Type-W'riting Machines, of which the following is a specilication.

Letters Patent for this invention have been duly granted to me, as follows: In Great Britain, No. 6,935, dated May 24, 1886; in Austria-Hungary, No. 47,566 and No. 11,812, dated November 7, 1886; in France, No. 177,787, dated August 5, 1886, and in Germany, No. 39,044, dated August 13, 1886.

My new type-writer combines both the capital letters, the small letters, the ligures, signs, and the punctuations, 82o., and is capable oi printing all of these, and it is of great simplicity and moderate cost.

In the accompanying drawings, Figure 1 is a plan view of my type-writer. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional elevation at the line my. In this gure the mechanism is shown at the moment in which it is printing one letter. Fig. 4 is a side elevation with a section through y z. Fig. 5 shows au inverted plan of the movable printer taken out of the apparatus.

In all the figures similar letters refer to simi-l f lar pieces.

On a plate, A, areafiXed-two guides, B B,

between which the beveled sliding footplate D is moved. The paper, F, is placed around the cylinder E,which is secured upon the footplate D, as it is shown by Fig. 4, and the paper is held in place by means of a fixed rod, G,

and a movable rod, G. The cylinder E is turned by means of a button, A ratchet or toothed wheel, e, and pawl e regulate the amount which the button E can be turned and determine herebylthe space between two lines.

A toothed rack, H, affixed to the foot-plate D, is intended to cause the paper to advance one or more teeth at a time for each letter printed. One guide-plate B bears a support, K, with a lever, k, pivoted thereto, and a pawl, 7c', engaging the tooth-rack H. On another support or post, L, affixed upon the plate A, bears a lever, Z, whose oftic'e is to put the pawl cout of gear by pressing the outer end ofZ downward with the nger, when the footplate D is to be moved backward in its slideway.

Upon the corners ofthe plate A are afxed three pillars, ac as, which bear a plate, A. There is a large circular opening in the plate A, closed by means of the disk I when the apparatus is at rest. Said disk or circularshaped plate I is aiixed luy-means of a central bolt, z', to a frame, J, hinged to the back edge of the plate A by means of hinges j. Plate I can be revolved around the bolt z'. A spring, j', also affixed underneath the plate A', presses the frame J, as well as plate I, upward, so as to maintain the same in the plane of the plate A', as shown by Fig. 2. The plate or disk I bears on its upper face two bracketed arms, C and S, of a peculiar shape and provided with knobs C and S. The lower face of I is provided with a circular range of types, one half of which is composed of capital letters and figures, the other half of small letters and punctuation-marks, as shown in Fig. 5.

Two springs, M M, alixed to the frame J, are provided with ink'ing-rollers m m, which are pressed against the types of plate I to ink the'same.

There is a stud, N, (see Fig. 2,) secured upon the under side of the frame J, and the oflice of said stud is to press down the lever la as the disk I and frame J are depressed in the act of printing, said movement causing the' track H and foot-plate D to advance one tooth, thus feeding along the cylinder E and paper, F. The plate A is, moreover, provided with a circular range of openings, O, disposed and formed so as to give passage to the pointed end of one of the arms G or S when the latter is pressed downward. Each of those openings is marked with aletter or a figure. The position of the arm C upon the plate I is determined in such a manner so that the companion letter or ligure of any selected capital letter or figure on the plate A, and which stands for the opening in which said pointed end is pressed down, shall simultaneously with such selection come in place and with the depression of the plate I be printed upon the paper, F. The position of hook S upon the plate I is determined nlike manner, so that the small letters and punctuations can in like manner be printed upon the paper, F.

The annularshaped opening Q, in the plate A permits of the passage of the pointed end ofthe arm Swhen the pointed end of the arm C' is pressed into one of the openings O in the4 act of printing, or the pointed end of arm G when S is pressed into one of said openings. An opening, It, placed at the periphery of the plate I, provides for supplying the inkingrollers m m with color when they become dry.

rIhe working of my type-writer is as follows: If you Wish to print, for instance, the capital letter A or the figure 5, you take in your hand the knob C and tur-n the plate I until the pointed end of arm C is placed over the opening of letter A or figure 5, and you press the knob down, and at the same time depress the plate I and impress the type A or ligure 5 upon the paper. If you have to complete a word--for instance,ApriW-you take hold ofthe knob S and turn the plate I in the direction of the arrow until the arm Ss placed over the opening marked I and press the knob downward. ThestudN operates upon lever k and pawl k', depressing them and moving the rack H, plate D, and cylinder E, and causing the paper, F, to advance the necessary amount, andjust as the feed is completed and the paper stopped, the type pis pressed downward and impressed upon the paper the right distance from A, and these movements are repeated for each letter printed. Thelever k is returned to its normal position by a suitable spring, or by a counter-weight, as shown by dotted lines in Fig. 2. lVhen the end of each line of printing is finished, the button Eis turned, revolving the cylinder and advancing the paper, F, a distance equal to one or more teeth of the rack e. The lever Z is pressed downward at its outer end, thereby raising its inner end, which lifts the pawl la out of the teeth of the rack H, and frees the rack, so that the sliding foot-plate D, the cylinder E, and paper, F, can be pushed backward to the starting-point, so as to begin anotherline.

I claim as my invention--` l. The plate A', having a central opening therein, letters, figures, and marks arranged in an arc around one side of said opening, and perforations in said plate opposite each of them, in combination with a pivoted frame, J, hinged to said plate upon one edge, a disk, I, pivotally supported upon said frame and having type upon its under surface in opposite sets near the periphery, inking-rollers upon arms secured to the frame J, arms and knobs C S, pointers C S', and a cylinder for the paper, and mechanism, substantially as specified, for operating the same, substantially as set forth.

2. The plates A and A' and con necti ng-posts, forming the frame of the machine, the plate A having a circular opening therein, in combinaton with the revolving type-disk I, the pivoted frame J, carrying said type-disk, the stud N upon the frame J, the post or support K upon the plate A, the lever k and pawl k', connected to said support K, the rack H, sliding foot-plate D, and the post L and lever Z, for releasing the rack and raising the pawl, substantially as specified.
