UNITED STATES HERBERT A. BRIGGS,

OF NEW YORK, N. Y.

ATTACHMENT FOR TYPE-V-WRITING MACHINES.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed February 16, 1905. Serial No. 245,937.

To all whom it may concern:

Be it known that I, HERBERT A. BRIGGS, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Attachments for Type-W'riting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to provide for a type-writing machine an auxiliary printing character-for exam ple,an underscoringcharacter-which at the will of the operator may be placed in operative relation with the regular printing instrumentalities of the machine to print the auxiliary character in its proper position as the regular type characters are formed, thus avoiding the necessity of the after manipulation of the work for the insertion or interlineation of the character.

In the hereinafter described structures, which embody my invention in a preferred form, an underscoring character is employed as the auxiliary character, to the use of which my invention is particularly adapted, and provision is made for the printing of this character simultaneouslywith the printing of the letter or character to which it relates; but, although I consider this simultaneous formation of the auxiliary character and its type character as of great importance, yet, except as expressly restricted by their phraseology, it is not my intention that my claims shall be limited to the employment of an underscoring character nor to the simultaneous formation of the auxiliary character and the particular type character to which it relates so long as the auxiliary character is formed in conjunc-' tion with the formation of a regular type character and during theordinary printing operation of the machine.

In the accompanying drawings, Figure 1 is a plan vies showing my invention applied to a writing-machine of the Remington type. Fig. 2 is a longitudinal vertical section thereof on the line 2 2, Fig. 1. Fig. 3 is a similar section, on an enlarged scale, showing the auxiliary character in operative position. Fig. 4 is a similar view showing the auxiliary-character 1 carrying device in engagement with the type-carrying member. Fig. 5 is a transverse section-on the line 5 5, Fig. 1. Fig. 6 is a section through the auxiliary-charactercarryingdevice on the line 6 6, Fig. l. Fig. 7

is a plan view showing my invention applied to a front-strike machine of the Underwood type. Fig. '8 is an elevation thereof, partly in section, viewed from rear of the machine. Fig. 9 is a similar view, somewhat enlarged, showing the attachment detached from the machine. Fig. 10 isa section on the line 10 10, Fig. '9; and Fig. 11 is a perspective view of one of the-attaching-clamps shown in Figs. 7 and 8.

Similar reference characters are employed to designate like parts inall the views.

I=have illustrated in-the drawings two specificstructures which embody my invention, one of which is adapted for attachment to an under-strike-machine, of which the Remington isa well-known type, and the other of which is adapted for attachment to a front-strike machine of the Underwood type; but it is to be understood that its use is' not restricted to these particular machines, since the structure can readily be modified for attachment to machines of other makes. The structures which I have selected for illustration may be manufactured as .a separate device, which may be readily attached to the machines and detached therefrom by an unskilled mechanic; but it is to be understood that the device embodying my invention may also be manufactured and assembled with the machine, so as to form an integral or inseparable part thereof, if desired.-

Referring first to the structure embodying my invention, which is illustrated in Figs. 1 to 6, A is a flat metal plate adapted to be secured to the top plate B of the machine by the screws 6 in place of one of the ribbon-guard plates with which the machine is provided, so as to be under the ribbon G and the ribbonguide 0. As shown in Figs. 1 and 5, the screwholes in plate A are somewhat larger than the screw-shanks to permit the plate A to be adjusted in exact position. The plate A is formed with a slot a, which coincides with the ribbon-slot in the top plate of the machine. An arm D is slidably secured to the under side of the plate A by the stud E, which extends through the slot F, and by the guides G, Fig. 5, formed in the plate A at the end of the slot a. The arm D is provided with a handle d, projecting beyond the side of the top plate B, by which the operator is enabled to shift the arm D toward and from the center of the machine, the limits of such move-' ment being determined by the length of the slot F. An arm Hot light stitf metal is piv: otally secured to the arm D and is supported,

acter-carrying device or member-is provided with an aperture 71, which is just large enough to permit eachof the outer or upper case type characters on the machine to enter it freely when the arm H is shifted toward the center 7 The free of the machine, as shown in Fig. 4. end of the arm H carries the auxiliary printing character to which I have referred, and which in the particular forms of apparatus herein illustrated is an underscoring character. This character is in the form of a dashshaped projection extending above the surface of the lever H, Fig. 6. As is well understood in the machines herein specifically referred to, each type-block K and its type-bar 7r; carry the regular printing type or characters of the machine, one of which, L, is operative with the platen in upper-case position, and the other of which, Z, is operative when the platen is in its lower-case position. I therefore provide two underscoring or auxiliary characters, one of them, M, for the upper case and the other, m, for the lower case. They are so formed on or secured to the arm H relatively to the aperture it that they will lie just under-that is, on the far side, Fig. 1, oftheir respective type characters when (with the arm H advanced to receive the upper-case character of any of the type-blocks) any one of the type-carrying members of the machine is actuated to bring its operative type to printing position.

In the normal operation of the machine equipped with my invention when the printed matter is to appear without underscoring the arms H and D are in their retracted position. (Shown in Figs. 1 and 2.) When, however, it is desired to underscore the work of the machine as it is written, the arms H and D are advanced by pressure on the handle d until such movement is arrested by the engagement of the studE with the end of the slot F. If then any one of the type-keys be actuated to bring its type-carrying member toward printing position, the far or upper case character will enter the aperture h until the portion of the type-block between the two characters engages that portion of the arm H which lies on the near side of the aperture 71,. When this occurs, the faces of the type and of the auxiliary characters will lie in the same horizontal plane and the continued upward movement of the type-carrying member will cause the operative type and its auxiliary character to strike the ribbon and make their impression on the paper in the machine. It will of course be understood that when the papercarriage is in lower-case position neither the upper-case type nor upper-case auxiliary characterwill make an impression on the paper, and when the carriage is shifted to upper-case position the same will be true of the lowercase characters. My invention thus enables the operator to underscore as much of the work as may be desired by the operation of the printing instrumentalities without requiring any after manipulation of the keys or other parts of the machine, and with the particular forms of my invention herein illustrated the underscoring of each letter is accomplished simultaneously with the printing of the letter. When the portion of the work to be underscored is completed, the arm H is retracted by the handle OZ and the normal operation of the machine is continued.

The modified form of my invention illustrated in Figs. 7 to 11 does not differ in principle, either of operation or construction, from that already described. As the machine to which it is shown attached is a front-strike machine, the auxiliary character carrying member is arranged to move in a vertical instead of a horizontal plane, and certain details of construction are changed to provide for this changed relation of the parts, and for the same reason the device is difierently supported. Its construction and operation, however, will from the foregoing description be readily understood by those familiar with the type of machine to which it is shown attached.

In Figs. 8 and 9 the device is viewed from the rear of the machine. The auxiliary characters N and n are formed on or secured to the resilient arm 0, which is provided with the type-receiving aperture 0,which, however, receives the lower-case character of each typeblock instead of the upper-case character as is the case with the device hereinbefore described. The lower portion of the arm 0 is widened and provided with two depending slotted arms which receive the stud-screws P, by which the arm 0 is slidably supported on the plate Q at the back of the type-guide R and between it and the ribbon-vibratorr. The plate Q is removably secured by the screwclamps q to the back of the sector-plate bracket S, and the middle portion of the plate Q is offset forwardly, so as to rest against the back of the sector-plate s. A bell-crank leverT is pivoted to the back of the plate Q, and one end of said lever is slotted to receive the stud p on the arm 0. The opposite end of said lever is pivotally connected with the arm U, which is provided with a handle a. The arm U is slidably held against the plate Q, by the flanged support or guide V, formed on the plate Q. A flat spring W, secured to the plate Q, bears against the under side of the arm U and cooperates with a stud w on the plate Q, which engages a notch formed in said arm to releasably hold the arm-U in the position shown in Fig. 8 and in full lines in Fig. 9 against the tension of the coil-spring X, secured at one end to said arm and at the other end to the plate Q. By pressing down on the handle a the operator releases the arm U from engagement with the stud w, and the coilspring X will draw the arm toward the center ofthe machine, actuating the bell-crank lever T to lift the arm 0 to bring the aperture 0 into position to receive the lower-case type of any character that may be struck by the operator. Each letter will then be printed with a simultaneously formed underscore mark made by the character N or n, depending on the position of the platen, until the desired underscoring is completed,when the auxiliarycharacter-carrying member 0 is retracted by drawing back the arm U until the notch thereon reengages the stud w, after which the normal operation of the machine is continued.

Having thus shown and described my invention, what I claim as new, and desire to secure by Letters Patent. is-

1. In a type-writing machine, an auxiliarycharaeter-carrying member adapted to be operated by the movement of any type-carrying member toward its printing position. and means for moving the auxiliary-charactercarrying member into and out of the path of movement of the type-carrying members.

2. In a type-writing machine, the combination of printing instrumentalities and means, operatively relatable thereto at the will of the operator, for underscoring the printed characters as they are formed.

3. In a type-writing machine, an auxiliarycharacter-carrying member common to all the type-carrying members and means for moving said auxiliarycharacter-carrying member into and out of the path of movement of the type-carrying members.

4. In a type-writing machine, a yielding arm carrying an auxiliary character common to the type characters of the machine, a typereceiving opening in said arm and means for actuating said arm to move said opening into and out of the type-receiving position.

5. In a type-Writing machine, a movable member carrying an auxiliary character common to the upper-case-type characters and an auxiliary character common to the lowercase characters of the machine, means for moving anupper or lower case character to the printing position, and means for moving said member into the path of movement of the type-carrying members.

6. In a type-writingmachine, the combination of a movable arm, ayielding auxiliarycharacter-carrying member supported by said arm, a type-receiving aperture in said member and ahandle secured to said arm for moving said aperture toward and from its typereceiving position.

8. In a type-writing machine, the combination, with type-carrying members movable singly toa common printing position, of an auxiliary character carrying member actuated by any one of the type-carrying members during the movement of the latter toward its printing position.

9. In a type-writing machine, the combination with a plurality of type and type-carrying members having a common printing position, means for moving them singly toward and from said position, and means actuated by the movement of any one of the type-carrying members toward said printing position for printing an auxiliary character as a type character is printed.

10. In a type-writing machine, the combination with printing instrumentalities adapted to print the type characters singly, of means for printing an auxiliary character simultaneously therewith and in the same letter-space.

. 11. In a type-writingmachine, the combination of printing instrumentalities and means for underscoring a printed character simultaneously with the printing thereof.

12. In atype-writing machine, the combination with the type-carrying members ,of a movable arm, a yielding auxiliary-character-carrying member supported on said arm, and a handle connected with said arm for moving the auxiliary-character-carrying member into and out of the path of the type-carrying members.
