SPECIFICATION forming part of Letters Patent No. 446,394, dated February 10, 1891.

Application filed August 26, 1889! Serial No. 321,974. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL J. Snrnnrnn, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Type.- \Vriting Machines, of which the following is a specification.

My invention relates to improvements in type-writers of that class wherein a rotatable type-sleeve is employed, and more particularly to improvements upon the type-writer shown and described in mypatent, N0. ilLOGG, granted September 17, 1889.

In my present improvement, as in my pre vious invention shown and described in said patent, the type-sleeve reciprocates parallel to the line of printing in either direction from its normal position for the purpose of bringing each and all the separate type or charactors on the type-sleeve into position longi tudinally in front of the impression-hammer; and the rotary movement of the type-sleeve serves to bring each of the separate type or characters on the type-sleeve into position radially in front of the impression-hammer, the radial and longitudinal movements of the type-sleeve taking place simultaneously.

In my present improvement, as in my previous machine, there are thirty keys and key- 3 levers arranged in three separate rows, the key-levers of each row having a common pivot, the key-levers of onerow operating simply to slide the type-sleeve without rotating it, and the key-levers of the other two rows operating to both slide and rotate-the type-sleeve, and

a series of vertically-slidingstop-pinsare employed for the purpose of limiting the movement of the type-sleeve.

My present improvement consists in the 4 novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts,

Figure 1 is a plan view of a type-writer embodying my invention. Fig. 2 is an end view. Fig. 3 is a central vertical longitudinal section on line 3 3 of Fig. 1. Fig. 4 is a rear 5 view. Fig. 5 is a plan view of the keys and key-levers. Fig. 0 is a detail plan view of one set of reducing-levers by which the mo tion of the key-levers is communicated to the stop-pins. Figs. Tand S are detail views of the escapement mechanism by which the spacing movement of the paper carriage or roller is controlled. Fig. 9 is a detail view of the segment-gear by which the type-sleeve shaft is rotated to bring the faces of the typesleeve which print the capitals or figuresinto 6o operation. Fig. 10 is a detail perspective view of the mechanism by which the motion of the key-levers is communicated to the type-sleeve. Fig. 11 is a detail perspective view of parts hereinafter to be described.

In the drawings, A represents the frame of the machine. The frame A is furnished with an interior frame or portion A, attached to the outer frame A by screws 60, and upon which frame A the key-levcrs are pivoted. The keys 1 are arranged in three rows of ten keys in a row. The key-levers B B 13 0f the three rows of keys are pivoted to shafts b Z) W, mounted on the vertical brackets A extending from the frame A.

O is the type-sleeve, and D D are the stoppins by which the radial and longitudinal movement of the typesleeve is regulated.

The frame A is provided with front and rear combs or slotted plates A At. which serve as vertical guides for each of the keylevers B 1-3 B The necessary rotary movement is com municated to the shaft 0 of the type-sleeve O by means of bars F F, which extend across all the key-levers 1%13 3 Asthekey-levers Bof the first row or rank of keys are required to communicate only a sliding movement to the type-s1eeve and are not required to give it any rotary movement, the key-levers B are furnished with notches b registering with the bars F F, so that when the key-levers B are actuated neither of the bars F F will be moved. The rotary movement of the typesleeve is communicated from the second row 5 of keys from their key-levers B by means of the bar F, and the key-levers B are furnished with notches I)", which register with the bar F, so that the type-sleeve rotating bar F will not be actuated by the key-levers B and the I00 key-levers B of the final row of keys actuate the type-slcevc-rotating bar F, these key-levers being provided with notches bflwhich register with the bar F, so that the bar F will not be moved when the key-levers 1% are actuated. By thus simply providing the key-levers B B B with notches or recesses properly registering with the bars F F, I am enabled to communicate the proper rotary movement to the shaft of the type-sleeve for each separate row or rank of keys.

The keys B are arranged in sets of three transversely to the rows, so that the same eonnectin g mechanism may be employed for communicating the necessary longitudinal movement for each set of three keys. One key of each set is found in each of the three rows or ranks of keys, the key-levers of each set bein g contiguous to each other. The necessary sliding or longitudinal movement is communicated to the type-sleeve G from each set of the three contiguous key-levers B B B by means of a rock-shaft G, having an arm g, furnished with a foot g, which spans the three keys of the set. There are ten of these rockshafts G, as there are ten sets of key-levers B" B B. The rock-shaf ts G are journaled in the vertical brackets A The type-sleeve shaft O is furnished with a sliding rotatable spiral gear G which engages a guide 0 mounted on the frame of the machine, and also a slotted guide C, secured rigidly to the shaft C, so that by slidin g the spiral gear 0 through the f rame-guide C the shaft 0 will be rotated and the necessary rotary movement will thus be com municated to the type-sleeve G, as the type-sleeve C is splined to the shaft 0. The necessary sliding movement is communicated to the spiral gear 0 from the key-lever-actuated bar F by means of a rock-shaft H,having an arm 7L, connected to abracketfon the bar F, which rock-shaft II is furnished with an arm h, which engages an arm 7; of a lever K, the upper end of which is furnished with a pin which engages an annular groove 0 in the spiral gear 0 In like manner the other bar F communicates the sliding movement in the opposite direction to the typesleeve through a rock-shaft ll, having arms 7L2, engaging ears f on the bar F. The rock-shaft H is furnished with an arm 7L3, which engages an arm k on the lever K, projecting oppositely from the arm k, so that the barF will communicate an opposite movement to the lever K and type-sleeve C from that communicated by the bar F.

The necessary longitudinal movement is communicated to the type-sleeve C from the key-lever-actuated rock-shaft G by means of arms 9 on the rock-shaft, which engage levers J, pivoted at j to the frame of the machine, and furnished at their ends with rollers or projections j, which engage cams a H, on the vertical lever N. The lever N is pivoted at N to the frame of the machine, and at its upper end it is furnished with a pin a which engages an annular groove 0 in the type-sleeve C. There are two levers J, one

located on each side of the machine, and the lever N is furnished with two cams n n, so that the key-levers on one side of the machine will operate to move the type-sleeve in the opposite direction from those on the other side of the machine. Thelever N is likewise provided with two projecting arms or, which are engaged by a bar or red m on the springactuated frame or lever M, so that the forks or arms a a will operate to return the lever N and the type-sleeve C to their normal or central position after each impulse or movement of the type-sleeve. The arms g of the rockshaft G are so rotated in respect to each other to the lever J and to the shape of the cams a a that each set of three key-levers will give the proper longitudinal movement to the typesleeve to bring the type actuated by such keylevers into proper position for printing. The type-sleeve O is furnished with a pin or projection c, which engages the spline or longitudinal groove 0 in the shaft 0. The shaft 0 has a pivot-bearing c c at each end for the purpose of reducing friction. The pivot c is fixed in place by a set-screw 0 so that the shaft C may be readily removed when desired. The type-sleeve C is furnished with a series of registering notches c at each end, of a semicircular form at their ends or bases, corresponding accurately to the size of the stop-pins D, with which they are to engage. The outer portion of these registering notches c is made curved or cam shape, as is clearly indicated at a, so that as the end of the typesleeve engages the stop-pin D the stop-pin will serve to not only limit the longitudinal movement of the type-sleeve, but also the radial movement of the type-sleeve, and thus lock and register it firmly and accurately in position, both radially and longitudinally. By thus causing the stop-pin to at once and positively register the typesleeve longitudinally and radially the printing will be done in accurate line and with proper spacing.

- The stop-pins D are ten in number, there being one stop-pin for each set of three keylevers 3 B B. Motion is communicated to the stop-pins from the key-levers through the same rock-shaft G and its arms g g by which the longitudinal movement is communicated to the type-sleeve. Each stop-pin is pivoted or otherwise connected to one of the arms 9 D representsthe holes or guides in the frame, through which the stop-pins reciprocate.

The return ing treadle or lever M is furnished with arms or branches M, which engage the stop-pin-operatin g levers, and thus insures the returning of the stop-pins to place. The side levers J J are also returned to place by this same returning-treadle M, the arms M having projections which fit over the levers J. The main returning-treadle M is also provided with branches or forks M which bear against the arms 7t and 7a of the typc-sleeve-rotating lever K, so as to return or bring the type-sleeve G to its normal position radially. The returning-treadle M is operated by a spring M .By thus con'ibining the type-sleeve-rotating mechanism, the type-sleeve-sliding mechanism, and the type-sleeve-registering mechan ism or stop-pins with one and the same returning-lever M, I am not only enabled to materially simplify the machine, but I also cure a more positive, accurate, and rapid movement.

The guide C before mentioned, which on crates to turn the spiral gear (1 as it reciprocates, I make in the form of a segment-gear, as is clearly shown in Fig. 9,so that by turning or rocking this segment I may change the case of characters which will be printed. The type-sleeve has nine faces. Three of these faces-ten characters in each face, or thirty characters in all-constitute the lowercase type. Three other of these faces constitute the capital letters, and the remaining three faces are for figures and other characters. 13 y simply turning the segment-gear C so that the spiral gear 0 will make one-third or two-thirds of a revolution, the capital or figure printing type will be brought into revolution. The segment-gear C is thus turned by means of a capkey 0 and lever O, which is connected to the segment-gear C by means of a link 0 and pin 0*, The figure-key P and its key-lever P are connected with this same link 0 Springs 0 and link 0 serve to return the levers O and P into place, respectively. The segmentgear C is furnished with a lip or projection C and a set-screw C for adjusting its normal position. A spring C holds the gear C normally in place.

Q and Q are the inking-ribbon spools. They are journaled on a pivotal frame Q havinga ribbon-guide Q", which partially encircles the type-sleeve C, an opening being left at the back or rear side for the impression-hammer R to strike through. A portion of this guide Q is preferably made movable, the movable part Q being pivoted to the main portion of the ribbon-frame Q The purpose of making a portion of the ribbon-guide movable is to lift the ribbon away from the type-sleeve when it is desired to remove the type-sleeve and its shaft from the machine. An inking-ribbon q passes from one of the spools Q through or over the ribbon -guide Q and transversely around the type-sleeve, and thence around the other pulley or spool Q. The ribbon-guide serves not only to guide the inking-ribbon, but also to hold the inking-ribbon out of contact with the type-sleeve, excepting at the instant when and at the point where the impressionhammer R strikes it. By making the ribbonguide of a curved shape, so that it partially encircles the type-sleeve, and by employing a narrow type-ribbon and arranging it so that it extends transversely around the type-sleeve,

the type-ribbon is prevented from hiding the printed line; and by employing a pivotal or movable frame for carrying the type-ribbon and its spools and guides, I am enabled to move the type-ribbon to one side, so as to leave the last Word or letter which has been printed open to view. To facilitate the removal of the type-spools Q Qfrom the frame Q I provide the frame Qj with pivoted arms q, having pins (f for the type-spools to fit and revolve upon. may be readily swung up into a position indicated by the dotted line in Fig. 3, when the ribbon-spool may be readily removed.

Each of the spools Q Q is furnished with a gear f q. The gears q each fit loosely on the shaft f and are furnished with pins (1, which engage a sliding clutch g splined to the shaft f, so that either one of the gears g" may be made to revolve with the shaft (f. A sliding rod (1 having a fork or arm q", serves to push the clutch q 'into engagement. with one of the other gears g", as desired. li y this mechanism either one of the spools may be driven in the direction necessary to wind the ribbon thereon, and then when the ribbon is all wound upon one spool by simply shifting the clutch g the other spool will be driven in the direction necessary to transfer the ribbon thereto. The shaft 1 is furnished with gear 1 which meshes with a worm s on the shaft S of the escapement mechanism, by which the movement of the paper-carriage is controlled. The impression-hammer R is actuated from the rock-shaft of the main returning-treadle M by means of an arm M and connectinglink 0', which extend under the key-levers, and is pivoted to the lower arm of the impres sion hammer or lever B. The paper-carriage T reciprocates on suitable guides or ways T on the frame of the machine, and is actuated by a main spring in the drum 25', through the connecting-strap The paper-carriage T is furnished with a rack T in which meshes a gear T on the escapement-shaft S. The escapement-shaft S is furnished with a sleeve S, carrying the worm s, and a pin-wheel s and a clutch .9 It is also furnished with a sliding clutch 5", held in place by a spring 8 which engages the clutch s. The shaft S is also furnished with a sleeve 5 and pinwheel 3", having a slot .9 through which a pin 3" on the pin-wheel before mentioned projects. A spring 5 connects the pin s" to the pin .9 on the back of the pin-wheel The sliding clutch s is actuated by a bent lever S which is held in place by a spring S The pin-wheel s is engaged by a pawl S", which is actuated by the key-lever or by the spaci ng-leverS, through the connecting mechanism. This eseapement mechanism is of an old and well-known form, and its operation will readily be understood by those skilled in the art. The sleeve S is loose on the shaft S, and the sleeve 5" is splined to the shaft S. The sleeve 5- is on the sleeve S. 13y thus combining the mechanism which operates the. ribbon-spools with the escapement mechanism I am enabled to continuously change the portion of the ribbon which is in use.

The paper-carriage T is provided with a paper-storage cylinder V, having an opening The pivoted arms q ICS or closing lip Y, adapted to receive and engage the edge of the paper. The paper-carriage is also furnished with a Iced-roller V the shaft of which has the gear 1.", that engages the spacin g-gear 1:. It is also furnished with a paper-feed lever r provided with a pivot-ed pawl 1". The pawl v is furnished with an arm 0", that engages a stop or projection r on the paper-carriage frame, so as to automatically lift the pawl out of engagement with the ratchet or paper feed gear when the paper-feed lever is in its retracted position. The paper feed lever is held in its retracted position by a spring o. A light spring o operates to throw the pawl into engagement with the ratchet at the first forward movement. of the paper-feedleverthat is to say, as soon as the paper-feed lever is moved the spring '0 at once throws the pawlinto engagement with the ratchet the moment arm r of the pawl is moved out of engagement with the stop v The distance between the lines to be printed is regulated by an adjustable or movable stop-pin r which fits in holes in the paper carriage frame, the series of holes being provided for the purpose of making lines closer together or farther apart, as may be desired. A thumb-piece V is rigidly secured to the paper-carriage frame adjacent to the paper-feed lever, so that the operator in taking hold of the paper-feed lever to feed the paper into position for printing the next line may at the same time and by the same movement of the hand push the paper-carriage to the opposite side of the machine or place of beginning.
