SPACING ATTACHMENT FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 777,262, dated December 13, 1904.

Application filed July 1'7, 1903.

T0 whom it may concern:

Be it known that I, WILLIAM ALFRED LY- MAN, a citizen of the United States, and a resident of San Francisco, in the county of San Francisco, State of California, have invented new and useful Improvements in Attachments for Type WVriters; and I do hereby declare that i the following is a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

My invention relates to that class of attachments to type-writers designed for the purpose of billings. tabulating, and spacing automatically; and it consists in the construction and operation of the stoppers and pegs which cooperate to obtain the desired space in one movement, thus simplifying the operation, as will be hereinafter fully described, and particularly pointed out in the claims.

Referring to the drawings hereto annexed, being made in three sheets and six figures, Figure 1 represents a side elevation of a typewriter frame provided with the improved attachment secured thereon. Fig. 2 is an enlarged rear elevation of the attachment and a portion of the rear end of the typewriter. Fig. 3 is a fragmentary sectional top view of the parts shown in Fig. 2 looking from the rear end of the machine, particularly illustrating the construction, arrangement, and operation of my improved stoppers and pegs as they appear when tabulating. Fig. 4 is a detached side view of one of the stoppers with a broken portion of its connecting-lever by which it is operated. Fig. 5 is a cross-section taken from dotted line 1 to 1 of Fig. 3. Fig. 6 is a longitudinal section taken from dotted line 2 to 2 of Fig. 5, showing the rack upon which the pegs are mounted broken away. Fig. 7 is a top view showing the projecting key-rods and their arrangement at the front end of the typewriter looking from the rear end of the machine; and Fig. 8 is similar view of Fig. 3, showing a different arrangement of the pegs, which are set particularly for billing purposes.

Like characters of reference made use of in the several figures indicate like parts wherever employed.

Serial No. 166,060. (No model.)

A denotes the general framework of an ordinary type-writer, and B a portion of its movable carriage mounted thereon.

Placed at the rear end of the frame A is the improved attachment, which is secured in po sition by the vertical frame C, as shown partially in Figs. 1, 3, and 8 and more particularly in Fig. 2, and consists of two vertical standards properly braced and adjustably mounted upon the framework of the typewriter. The standards project outwardly at their upper ends to provide suitable brackets for the stoppers D, between which brackets said stoppers are adjustably mounted and supported in position by means of two screwbolts a, secured to the standards C and pass ing through slots 7) made upon the stoppers, as particularly shown in Figs. 3 and a and 8. For the purpose of this application I have shown eight stoppers 1), having their slots 7) of different lengths, whereby said stoppers are adapted to project different distances from their brackets, and said stoppers are shown as mounted between stationary dividing-strips c and as adjusted by means of vertical levers E, which are mounted between the standards of the frame C and upon a bolt (Z, which bolt constitutes the fulcrum of said levers. The upper end of the levers are pivoted to the stoppers substantially in the manner shown in Fig. 4-, while their lower ends are connected to horizonal key-rods F, secured beneath the frame A of the type-writer, and control their movements. The key-rods are provided with spring 6 to keep them in proper position and project outwardly from the front end of the frame A sufficiently to facilitate their operation, as shown in Fig. 7

Mounted. horizontally upon the movable carriage B and held in line with the stoppers D at suitable distance away by brackctsf is a toothed rack H, upon which a desired number of bifurcated pegs g are interdentallysecured and project outwardly in the direction of the stoppers, as particularly shown in Figs. 3, 5, 6, and 8. These pegs are constructed of different lengths corresponding with the travel of the stoppers, as plainly shown in Figs. 3 and i, and are provided with side reinforced ribs it to keep them rigid when in position upon the rack H, and the number and location of these pegs is intended to indicate the number of columns and spaces desired between them when billing or tabulating.

In practice the key-rods F, which correspond in number to the number of stoppers, may be identified in such manner to suit the operator; but for the purpose of this application the stoppers and pegs are numerically and correspondingly markedviz., 1 to 8to demonstrate their relation when in operation, which is as follows: If column 1 is desired, the corresponding key-rod F is pressed forward, thus moving inwardly its stopper into the path of travel of peg No. 1 and also releasing by the usual mechanism (not shown in the accompanying drawings) the carriage bearing the rack H, permitting the same to move and bring the peg No. 1 in contact with the stopper No. 1, as shown in Fig. 8. I then release the key-rod, which is returned to its normal position by means of spring 0 and carries the stopper D to its normal position, thus leaving the carriage in the place desired. As a further illustration, if column 5 is desired the corresponding key-rod is pressed forward and moves inwardly its stopper, which being shorter in travel passes over the pegs Nos. 1, 2, 3, and et and comes in contact with peg No. 5, thus obtaining the desired column in one operation instead of four stops, as will be otherwise the case.

Believing I have made useful improvements in spacing attachments to type-writers and greatly reduced thereby unnecessary work and having described the same, what I claim as new, and desire to secure by Letters Patone of said pegs, and means for projecting said stoppers different distances to cause them to engage their respective pegs, substantially as set forth and for the purpose specified.

2. A type'writer attachment comprising a series of pegs arranged along the length of the carriage of the type-writer and projecting therefrom successively increasing distances, and a corresponding series of suitably-supported stoppers each for a different peg of said series of pegs, said series of stoppers being movable to project different distances from their supporting means into the path of the pegs, respectively, and means for adjusting said stoppers independently of each other.

3. In an attachment to type-writers for billing, tabulating and spacing provided with a series of movable stoppers having slots of different lengths cut thereon, in combination with screw-bolts passing through the slots and adapted to support them in position, and regulate their travel, substantially as set forth and for the purpose specified.

In testimony whereof I hax e affixed my signature, in presence of two witnesses, this With day of June, A. D. 1903.

W'ILLIAM A. LYMAN.

In presence of B. AsoH, J. ComNsoN.
