TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 707,882, dated August 26, 1902.

Application filed April 10, 1902.

To all whom, it may concern: 7

Be it known that I, J OHANNES HENDRIKUS VINK, a subject of the Queen of. the Netherlands, residing at Kleine Overstraat 45, Deventer, Netherlands, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

The present invention relates to a typelever for type-writing machines, in which the types in their position of rest lie against an inking-cushion and on striking the key-lever are turned in such a way that they apply the ink directly to the paper. This invention differs from known constructions of this class in that the type-baris pivoted to a lever so as to oscillate on an axis normal to the longitudinal direction of the lever, and that this oscillating motion is produced by the motion of the key-lever through the agency of a sliding rod connected at one end to the frame and engaging at the other end in a guiding-slot in the type-bar carrier.

In the accompanying drawings, which illustrate the invention, Figure l is a side elevation showing the type-leverin its position of rest. Fig. 2 is a front view of the same, omitting the bed, key-lever, and platen. Fig. 3 is a side elevation showing the type-leverin printing position.

The type-lever a is produced from a sheetmetal blank of suitable form by bending the two sides together on longitudinal lines, so as to bring them in parallel position at right angles to the connecting back a This connecting back is limited to the central part of the lever, leaving open spaces between the sides at a and a. to permit the movement of the parts, as hereinafter described. At the upper part of the lever is a special type-bar carrier 19, pivoted to oscillate on the pin 61. On this type-bar carrier is mounted a typebar 0 of suitable form, having one or more types. The type-bar-carrier b is adapted to turn in the fork-like upper end of. the typelever a and is provided with a curved guiding-slot f, which receives a slide f on the upper end of a rod g, extending downward and guided between the two sides of the lever a and pivoted at its lower end to a link i, which is pivotally connected to a standard on the frame. The upper end of the rod g is guided Serial No. 102,256. (No model.)

by its connection With the type-bar carrier 1) through the slidefand also by a pin 0, fixed in an outward bend of the rod g and sliding against the back of the type-lever a, for which purpose the opening a in the lever is provided. The lower end of the rod projects through the opening (t and is guided between the back a and a fixed transverse pin hiu the lever.

The type-lever a, is fulcrumed at its lower special projection on which also serves for pivotal attachment of the link t'. A rod Z, pivoted to a bifurcated lug on the lower end of the type-lever a, communicates motion thereto from the key-lever m, which is pivotally fulcrumed on the bed of the machine and is pressed upwardly by a spring 1).

The operation of the device is as follows: The parts being at rest, as shown in Fig. 1. upon moving down the key-lever m the rodl is drawn down, and thereby the type-lever a brought to the horizontal position. (Shown in Fig. 3.) In this movement the rod t' draws down the bar g, which through the medium of the slide fproduces rotation of the type-bar carrier 1) on the pivot d, and the slidef, trav ersing from one end of the slot f to the other, turns the type-bar carrier 1) and with it the type a through an angle of one hundred and eighty degrees on the lever a. The device thus takes the position shownin Fig. 3. When the key-lever m is released, the latter rises under the influence of the spring P, the typele'ver a is restored to vertical position, and the pressure exercised by the bar 2' on the bar 9 slides the latter upward and by the pressure of the guided bar 9 and the slidef, acting in the specially-formed slot f, the type-bar is returned through an angle of one hundred and eighty degrees to its first position. In the position shown in Fig. 3 the types are turned downward and can print upon paper passed over a roller or platen, whereas in the position of rest (shown in Fig. 1) they may lie against a suitably-arranged ink-pad. If the type bar is provided with a plurality of'types, as is shown in the drawings, then by adjustment of the platen-roller n one type or another is used for printing in customary manner. As

the mechanism for turning the type-bar carrier Z) can be so formed that the oscillating end on the bearing-block or standard 70,21.

7 carrier 1) pivoted to the end of the lever to; and the guided bar 9 sliding in the cavity of the type-lever a, connected at one end by the rod 11 to the standard 70 and at the other end to the type-carrier b and imparting oscillatory motion to said type-carrier by the movement of the lever a, as explained.

2. The combination of the standard is; keylever m; typelever a, and connecting-rod Z pivoted to the standard 7c; oscillating typebar carrier 1), having a curved slotf and pivoted on the free end of the lever a; type-bar c mounted on the carrier b;'sliding bar 9 connected at one end to rod 1 and guided in the lever a by pins 0 and h and the slidefworking in the slotf and communicating, oscillatory motion to the type-bar carrier by the movement of the lever to on standard 70, substantially as described. y

In testimony whereof I have hereunto set my hand in the presence of two witnesses. J OHANNES HENDRIKUS VINK. WVitn esses:
