TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed July 8, 1905. Serial No. 268,777.

' citizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is aspecification.

This invention relates to improvements in the type actionsof typewriting machines, it being especially applicable to visible writing machines of the style called front strike machines.

The object of the invention is to so impro-ve the construction of the type actions as to relieve all of their parts from injurious torsional strains, to. equalize the depressions of the finger keys, and to secure. other benefits affecting .the operation of the. mechanism, and includes the provision ofmeans embodied in the type bars and type bar rest for preventing any of the type barsfrom rebounding into the path of another.

This invention consists of all the various; features of construction, combinations and; arrangements of parts, which are hereinafter described and specified in the appended claims.

On the accompanying sheets of drawings, in which like reference numerals designatelike parts in different views, ,Figure 1 is a side and sectional elevation of portions of a front-strike typewriting machine, including mechanism representing the invention;

Fig. 2 is a front and sectional elevation of some of the same and other portions of this machine, certain connecting links being indicated by single lines; and Fig. 3 is a lan of some of the finger keys and a part 0 the mechanism operative thereby to actuate the type bars, the single lines at the left of the devices which are fully shown in plan, illustrating connecting links.

The frame of the machine is composed of a rectangular body 1 on which are posts 2, and of a top-plate 3 fastened on the posts 2. The top plate has in it an opening 4 through which the type-bars move toward and from the platen 5. A type bar segment 6 is secured in the frame under the front of the platen. It may be attached to the top.

plate by screws 7 passing through lugs 8,

formed on the ends of the segment, into threaded holes in the top plate as appears by Fig. 2, or may be confined by other means on four axes 13, 14, 25 and 26.

- Patented June 25, 1912.

lies in a groove in the segment and passes through all of the type bars. The type bars normally extend toward the front of the machine from the segment to a type bar rest 12, by which their front ends are supported. Each type bar is movable on its pivot from its normal position to its printing position, the type bar which is shown in Fig. 1 being represented by dotted lines in that figure in its printing position.

In the front part of the frame of the machine are fixed two round cross rods 13 and. 14, whose axes are parallel to the axis of, the platen and in a vertical plane. These rods are attached at their ends to the sides of the frame. Two series of parallel angular levers 15 and 16 on which are formed hubs 17 and 18, are loosely mounted on the rods 13 and 14, the levers being arranged in' pairs as shown, each of the levers 15 being over a lever 16. To each of the forwardly projecting arms of each pair of these levers, these arms being of equal length, is pivoted an upright link 19, having an extension on which is a finger key 20. The extensions'of the links are properly formed to secure the arrangement of the finger-keys in banks, the extensions 21 on which the finger keys of the uppermost bank are mounted being prolongations of the links on which they are formed, and the other extensions 22, 23 and 24, projecting (litlerent distances in front of the links, in rows of different heights. Since the lovers 15 and 16 are parallel .and the axes of the pivots 25 and 26 are equally distant from the vertical plane containing the axes of the rods 13 and 14,'th levers of any pair may be turned together on their pivotal -axes by depressing the fingerkey connected with them and each'link 19 turns To the rear ends of each pair of the parallel levers described is pivoted an upright link 27, comprising upper and lower arms 28 and 29 which project in front of the upright portion of the link and are pivoted respectively to the upper and lower levers of the pair by pins and 31, the upright portions of these links 27 being behind the vertical plane containing the axes of the rods 13 and 14, and lying normally close to the type bar rest 12. The links 27 therefore are likewise arranged to turn on four axes, the fixed axes or pivot rods 13 and 14 and the movable axes or pivots 30 and 31. Those links 27 which are in front of the middle portion of the type bar segment are provided with extensions 32 at their lower ends, and each of the two links at the ends of this series has on its upper end an extension 33. Connecting links 34 are ivoted at their front ends to the upright llnks 27 by pins 35, and at their rear ends to the type bars by pins 36. The front ends of the connecting links are pivoted to the upright links at elevations which progressively increase from the middle to the sides of the system of type actions. To each connecting link 34 is attached a restoring spring 37, which is also attached to a curved cross bar 38 fixed under the typeloar-segment.

The operation of the type actions described is indicated by dotted lines in Fig. 1, which represent the positions of the parts of one of the type actions at the end of a printing movement of the type bar. lVith the depression of the finger key the angular levers are turned on their axes, the pivots 30 and 31 being carried toward the front of the machine on arcs whose chords are substantially horizontal, and the link 27 is drawn forward, pulling with it the connecting link 34,'the result being that the type bar. is swung to its printing position. It will be understood, since four of the pivotal axes of every type action are parallel to one another and the links 34 are nearly horizontal and converge but slightly from the links 27 to the type bars, that. only small torsional strains will be produced either at the sides of the system or else where, and it will also be seen that the dip of each finger key will substantially equal that of every other, for substantially equal movements of the links 27 are required to actuate the type bars, and that the faces of the linger keys are constantly horizontal.

The type bar rest 12 is fixed in its relations to each of the type bar pivots. In 1nachines in which the type bar segment is movable toward and from the platen, the type bar rest is to be attached to supports 46 projecting from the segment. The face 39 of the rest, and that part 40 of the edge of the type bar which makes contact with the rest, are preferably formed and arranged as represented in Fig. 1 of the drawings, but it is not necessary that the form of either the rest or the edge of the type bar should be nreeisely as shown. Their relations are to be such, however, as

to render the angle of incidence of the type bar on the rest a large acute angle, whose complement is equal to the angle included by the faces of a wedge, and consequently to subject the type bar and its pivot to pressure acting lengthwise of the type bar, when the latter strikes the rest on returning to its normal position. The face 39 of the rest is shown in the form of a section of the surface of a blunt cone, whose axis is on a horizontal line 41 cut-ting the platen at the printing point, and whose apex is at the point 42 on the line 41, in front of a vertical plane parallel to the axis of the platen and cutting the typebarrest. The base of this cone is, therefore,

vertical and forms with any of the ele the lines' 43 and 44 intersecting each other a at the point 45. This angle of incidence therefore is considerably greater than an angle of forty-five degrees, and its complement, represented by the lines 42 and 43, is equal to the angle included by the faces of a wedge. By subjecting the type bars to pressure acting lengthwise thereof as explained, each of the type bars may be prevented from rebounding into the path of another even when the machine is rapidly operated.

Various changes may be made in the mechanism above described without departing from the invention herei'n set forth and claimed.
