TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 491,071, dated February '7, 1893.

Application filed March 26, 1892. Serial No. 426,505. (No model.)

.To a/ZZ whom it may concern,.-

Be it known that I, GEORGE C. BLIoKENs- DERFER, a citizen of the United States, residing at Stamford, in the county of .Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type- Writ'- i ing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to type-writing machinesand consists in certain improvements in the construction thereof, as will be hereinafter fully set forth and pointed out in the subjoined claims.

The invention is illustrated in the accompanying drawings as follows:

Figure 1, is a top or plan view of a typewriter, such as is shown in Patent No. 459,093, granted to me on the Sth day of September, 1891. In this illustration all of the type keys except one are omitted, and also the type wheel. Fig. 2, is a side elevation of the frame work of the machine shown in Fig. 1, looking at the left hand side of said figure. In this illustration the key-mechanism is omitted and also the paper carriage, type wheel, and so forth, leaving only the carriage, driving shaft and the means for actuating the same. Fig. 3 is a perspective view of the parts shown at the left of Fig. 2, namely the carriage driving shaft, F, the gear for moving said shaft and the lever for moving said gear. Fig. 4 is a perspective view of the ruling devices E, E, and the feed actuating cam D, seen at the left of Fig. 1. Figs. 5 and 6 are detail views, that will be explained in place hereinafter. Fig. 7 is an end elevation of the carriage looking from the left of Fig. 1, with the ratchet wheel b and the hand wheel b, omitted. Fig.

`El is a detail view that will be referred to in place hereinafter.

The purposes of the invention are, first, to provide improved means for returning the paper carriage to its normal position; second, to provide means for automatically actuating the feed rollers of the carriage as the carriage is returned to its normal position; and, third, to provide improved means for drawing lines upon the paper, such as underscoring, ruling, &c. These several improvements are not limited in their use to machines `of the type shown in the drawings, but may be applied i to many different types of type-writing niachines, and therefore I do not desire to be understood as limiting my invention to any particular type of machine, although it may often be necessary to modify and change the construction here illustrated, in order to adapt the invention to various types of machines. Such modifications, however, will not alter or abridge the essential elementary features of my device, and any person skilled in the art will have no difficulty, after having become familiar with the construction here shown, in adapting my device to most of the various type-writing machines.

The invention as applied to :the machine shown in thea'ccompanying drawings, is constructed as follows:

A designates the frame of the machine; B, the frame of the carriage; B' the large paper roller or platen; B2 the shield or guide which holds the paper in contact with the platen; B3 the small feed roller or presser roller.

b b, are the hand wheels at each end of the platen, for manually turning it.

b is the ratchet wheel upon which the actuating pawl operates, and it is on the shaft of the platen the same as the hand wheels.

These j ust named parts are the same as shown i in my former application, Serial No. 410,230, filed the 29thday of October, 1891.

C is the pawl which acts upon the ratchet b', and it is pivoted at c on a plate C that is journaled at c concentric with the ratchet b', on the shaft of the platen, and serves as a pawl carrier. This plate C has two limiting faces, c2 and c3 which act upon the limiting screw b4 and the lug b3 and thus limit the movement of the said plate and its'sup- IOO scribed, mechanically by the action of the machine. On the outer end of the pawl O there is an antifriction roller c4 and on the frame piece A2 of the machine is a cam plate D, in position to contact with the pawl-arm when the carriage is returned to its normal position, that is, into position to commence a new movement to the left. As the carriage is completing its movement to the right, the pawlarm comes in contact with the lower part of cam D and runs up its inclined face. This lifts the pawl-arm up and moves (by means of the ratchet b') the platen to position the paper for a new line. The cam D is of suflicient length to move the pawl through its farthest limit of action, and it will, of course, move the pawl through any lesser limit of action properly, because such lesser movement will be effected by the upperfpa'rt of the'cam. As the carriage moves tothe leftin printing a line, the pawl arm leaves the cam, and returns to its normal position vby the action of the returning spring c5 shown in Fig. 7. It will thus be seen that the pl atenwill'be turned to position the paper for a new line by simply drawing the carriage back to the position to start a new line, and itmay also be turned to feed the paperby manually lifting thepawl arm. Hence when a double space between lines is wanted, the operator will manually lift the pawl-arm and let it 'react before he returns the carriage `to normal; audit will yalso lbe seen that the space between the lines is regulated by adjusting the limiting screw b4. On aquadrant formed arm b2extending froin'the frame work B, as seen in detail in Fig. 8, there is a scale by which the width of line-spaces is indicated'to the operator byobserving the posit-ion of the 4point 'c6 on the pawl carrying plate C', relative tosaid scale.

In the construction here shown the means formovingthe carriage to theleft while printing 'are the same as shown in my aforesaid application serially numbered 410,230, namely apropellingv shaft F having thereon, a pinion jF3 shown in Fig. 2 which gears with a rack on the carriage not shown in said figure; a ratchet 'F' acted upon `by`a pawl T4 that receives its action through the type-keys T and the intermediate gearing T', T2, T3; and a second ratchet F2 (Fig. 2) which is acted upon by the pawl S4 that receives its action from the spacer-key S and'intermediate gearing S', S2, S3, and S5; and here, as in the application above referred to, the 'pa'wls S4 and T4 are normally out of contact with the ratchets upon which they respectively act, and hence the shaftF, is normally freeto be revolved by the movement of the carriage manually or by other means than the type-key and spacerkey action; and therefore, the carriage is normally free to be moved manually or by other means than by the action of the keys. In this construction I have provided means for rotating theshaft F by the action of a lever, in a reverse direction from that in which it is moved by the action of the key mechanism,

which mechanism is normally free from the shaft and therefore does not interfere with its movement when actuated by the key mechanism. The object of this added mechanism is to enable the operator to return the carriage toward the right for beginning a new line by the manipulation of a special lever or key. The construction of this added mechanism as illustrated is as follows: On the shaft F there is fixed a clutch f, and loosely sleeved on said shaft is a worm-pinion G' having at its end a clutch formation g, to engage the clutch f.

On a part A4 of the frame work of the machine is journaled a worm-wheel G which meshes with the worm-pinion G. Attached to this worm-wheel isabeveled spur-gear H2. On a lever II, which is pivoted to the frame A at h, is a bevel-geared quadrant H', meshing with the'gear H2. Hence by moving the lever H, the worm gearing G, G, will lbeactuated. The worm-pinion G' is sleeved'on the shaft F so as to rotate freely thereon. It `is also free to move longitudinally of the shaft to a limited extent. The action of 'the two parts G and G' upon'each other 'causes the part `G to move back and forth longitudinally on said shaft at the same time 'that it is oscillated or rotated back and forth on said shaft. The longitudinal movements throw the clutch-formations g' andfinto andoutof action upon eachother according to the direction of motion of the parts G, G'. Therefore, when the worm-wheeljGis rotatedso as to turnthe worm gear toward the Iright hand side ofthe machine, the clutche's'gandjc will engage and lthe yshaft F will be rotated toward the right. This will draw the carriage back toward the right, and when the action of the wheel'G 'is reversed, the clutches will not engage'but will separate and the shaft F will not be moved. 'When the shaft F is turned toward the left by the actionof the type keys or the spacer key, the clutches g iand f will quickly become disengaged because lwhen the worm-gear G' is turnedtorward theleft it is moved, bythe action ofits teeth upon the vteeth of the'wheel G, outof contact with the clutch-party. On the frame A, under the worm gear G', I attach a spring g 'which presses against the worm-gear and acts as a break'to 'steady its action-and prevent it slipping out of Vengagementwith the clutchyC too easily. ltwill therefore b'e-observed that, when the 'carriage has reached its limit of movement toward'the'left, and is ready'to be returned tothe position to commence a new line, the operator by moving the lever H, draws the'carriage back tonormal and at the same time 'moves the pawl C up the inclinedface of the cam D and thusv not only is thecarriage returned to normal but theplaten is turned so 'as to movev the paper into position to receive a new line of printing.

The means for automatically turning `-the paperroller and the means for'returning the carriage to normal need not necessarily be IOC IIO

yupon the paper are shown in Figs. 1, 4, 5 and 6, and consist of a cylindrical head E, on a rod or shaft E journaled on the frame pieces A', A2, at ct and a2, and havinga handle e at theend of the shaft E nearest the operator. In Fig. 5, the head E is shown in longitudinal section and the ruling wheel e and ink roller e2 are displayed in elevation. At a convenient point on the rod E there is an arm e3 carrying -a pin e4 and on the adjoining frame piece A', there are three holes a into which said pin can enter, and when entered the shaft or rod can not turn. These holes d are so placed that if the pin e4 is in the upper one the wheel e will be in position to draw a horizontal line on the paper, and if in the lower one the wheel will be in position to draw a vertical line on the paper, and if in the iniddle hole the Wheel will be in position to draw a diagonal line on the paper. A spring e5 is provided for holding the shaft E in such a position that the pin e4 will enter the upper hole a, when the shaft and head are moved longitudinally. I adopt this as a normal po- -sition because horizontal lines are more often drawn than any others. I provide two ruling devices so that lines in two colors can be drawn.

The operation of ruling is as follows: The operator, to draw a horizontal line will push the rod E longitudinally and this will press the wheel e against the paper and it will enter the pin c4 in the upper hole d and so lock the rod against turning. He will then draw the carriage one way or the other, as he pleases, and this will effect a horizontal ruling on the paper. If he wants to draw a vertical line he will turn the rod so the pin c4 will enter the lower hole ct and then push it ir. so as vto press the wheel e against the platen, and then, while holding the ruling device with one hand he will roll the platen with the other hand acting upon one of the hand wheels b. If he desires to draw a diagonal line he will proceed as before only entering the pin e4 into the middle hole and he will draw the carriage longitudinally while revolving the platen.

In Letters Patent No. 457,333, issued to me August 4, 1891, and in Nos. 459,093 and 459,094, issued to me September 8, 1891, I have shown, described and claimed means for drawing lines upon the paper, and I do not intend to here claim the invention there shown and claimed.

The advantages of my present construction are that the ruling devices can be turned so that the same ruling wheel can be used to draw horizontal, vertical and diagonal lines, whereas in my former constructions a different ruling wheel wasused for drawing differently directed lines. Y

A further advantage exists in the provision of means for operating the ruling devices without reaching over the machine. The first of these advantages is attained by journaling the head carrying the ruling wheel on an axis that is at right angles to the axis of the platen, whereby the said wheel may be presented to the platen with its axis at right angles to the axis of the'platen or parallel with the same or at an angle intermediate thereof.
