SPECIFICATION forming part Of Letters Patent No. 623,451, dated April 18, 1899.

Application filed November 5, 1897. Serial No. 657,579. (No model.)

To (LZZ whom it may concern: 7

Be it known that LOORALNOVELLO Wnsr- WOOD,of Nanaimo,l3ritish Oolnmbia,Canada, have invented a new and useful Improvement in Type-lVriterAttachments, of which the following is a specification.

It is the object of this invention to provide improved means for column-spacing, linespacing, and back spacing in type-writing, say, on machines of the Remington andGaligraph type. The invention is embodied in mechanism attached to the right-hand side of such a machine and which is so connected with the rotary cylindrical platen and its reciprocatory carriage as to adjust one or both, as required, for effecting either column, line, or back spacin The construction, arrangement, and operation of such mechanism are hereinafter described,and showninthe accompanying drawings, (three sheets,) in which Figure 1 is an end view showing my improved attachment applied to a Oaligraph type-writing machine. Fig. 2 is a side or face view of the same. Fig. 3 is an enlarged horizontal section, on line 3 3 of Fig. 2, of'a portion of the attachment. Fig. 1 is a vertical section on line 4 4 of Fig. 3. Fig. 5, Sheet 2, is a rear elevation of the attachment applied to a Oaligraph machine. Fig. 6 is an enlarged face view of a portion of the apparatus, part being broken away. Fig. 7 is a detail section of parts shown in Fig. 6. Fig. 8, Sheet 3, is a plan view of the attachment. Figs. 9 and 10 are plan and side views illustrating the treadle mechanism. Fig. 11 is an enlarged longitudinal section of the platen and some of its attachments.

I will first describe the means for releasing the platen and allowing it to run forward and stop it at certain points.

A cylinder 1 (see Figs. 1, 2, and 8) is secured by screws to the front and right-hand side of the type-writer frame 2. In the vertical face of said cylinder 1 a series of push-keys 3 are arranged in a circle to work in horizontal guides, their enlarged heads bearing numerals 5, 1O, 15, and other multiples of live corresponding to numbers inscribed on the scale or gage plate 2, Fig. 2, ordinarily used on typeavriting machines. The heads of these keys 3 are adapted to bear upon the outer ends of a series of levers 4, Fig. 3, ar-

ranged radially on the face of the cylinder 1, with their convergent inner ends engaging jam-nuts 5, applied to a shaft 6. The levers are pivotedon a wire extending around a circular flange. The shaft 6 passes transversely through the cylinder 1 and across the end of the type-writer frame 2 and is further supported horizontally by a bearing on the latter, as shown best in Fig. 1. On the rear end of the shaft 6 are mounted a drum 13 and ratchet-disks 8 9, which will be hereinafter described in detail. The shaft 6 is slidable longitudinally and also rotatable. It is slid forward by depression of a key or push-pin 3, which thereby tilts a lever/l, which in turn acts on the jam-nuts, as shown by dotted lines, Fig. 3. The object of this movement of the shaft 6 is to momentarily release the ratchet-disks 8 9 from engagement with a pawl 10, Fig. 5. The pawl proper is pivotally attached to a vertical arm or standard 10, that forms a fiXed attachment of the rocking bar or frame 11 usually employed on typewriters of the class hereinbefore referred to. Consequently the pawl 10 oscillates laterally with said bar 11 as the'latter rocks, and it is provided with a plate-spring 12 for holding it normally engaged with the ratchet-disks S and 9.

The drum 13,Fig. 1, is secured on shaft 6 and has lateral flanges,as shown. The ratchet-disk 9,Fig. 6. is secured ad justablyto the outerside of the drum 13 by means of screws 14, that pass through arc slots 15. The object of this adjustment of the disk 9 is to enable it to be set.

circumferentially, whereby to coincide with the ratchet-disk 8 and form part of the mechanism for moving the carriage forward step by step,which mechanisml shall now describe. It

will be understood that said disk is normally fast or fixed on the drum 13 when in use. The other disk 8 is, however, loosely mounted on the shaft 6, but its circumferential movement is limited by screws passing through are slots 17 and entering shouldered studs or the spring 19 normally holds the outer diskS IOO in the position shown in Fig. 6, in which its teeth register or coincide with those of the inner disk 9, so that the pawl may slide laterally from one disk to the other when oscillated by the rocking bar 11, as before stated. In further explanation of this part of the attachment I will state that when the pawl 10 is cantedor moved inwardly it is carried from the loose ratchet S into engagement with the fixed ratchet 9, and the former, 8, being thus left free is rotated and carried forward one notch or tooth by the tension of spiral spring 19. On rel urn of pawl 10 to its normal position in contact with the loose ratchet 8 the platen-frame is allowed to move forward one space by means of the arc slots 17 in ratchet 3. Thus the movement of the pawl 10, as described, allows for a letter or letter-space in the writing done by the ma chine. \Vhen the shaft 6 is drawn forward by a push-key 3 and lever 4, as before described, the loose disk 8 may be freed from the pawl 10. A cordor suitable wire cable 20, Fig. 5, is secured at one end to the drum 13 and at the other to the platen-frame 21, passing intermediately over an idle pulley 22 and through a guide 23, whereby it will be seen that the shaft 6 is rotated when the platform 21 is slid. A binding-screw serves to secure the cable to platen-frame and as a means for taking up slack when required. This cable is provided with a spring attachment 24, preferably formed of a spiral spring arranged between two disks that slide on rods to which the respective divided portions of the cable 20 are attached. The function of the spring 24is to to relieve shock on the cable 20 when operating the. platen that is to say, when the movement of 'the platen is checked. It will be understood that the function of the pull cord or cable 20 is to produce forward and backward movement- 1'. e., reciprocation of the platen.

Returning now to Fig. 3, it will be seen that the shaft 6 has a radial arm 26, which is fixed thereon, and hence moves with it. When a key 3 ispushed in, it projects into the rotary path of this arm, and therefore serves as a stop for limiting the rotation of said shaft. A pull-cord 27 is applied to the drum 13 and Winds thereon in a direction opposite the cable 20. This pull-cord is connected with a treadle, as hereinafter described.

The following-stated conjoint operation of the parts before described will now be comprehensible. Say it is desired to allow the platen to run forward (or to the left) until the pointer, Fig. 2, is opposite the numeral on the scale-bar 2, it being assumed the platen has been drawn back to the right-hand position shown in said figure. The operator presses inward that one of keys 3 whose head bears said numeral, and thus tilts the connected lever 4, which in turn acts against the jam-nuts 5 and draws the shaft 6 forward, together with its attachmentsnamely, the arm 26, drum 13, and ratchet-disks 8 and 9,

' which latter are thus freed from the pawl 10.

Then the shaft 6 is free to rotate, so that the platen 25 and its carriage 21 move forward or to the left until the arm 26 of shaft 6 in the course of its rotation strikes the key 50, (which is still held depressed by the operator) and thus the platen'carriage is stopped with the pointer at 5O on the scale. If now the key 3 be released, the shaft 6 will slide back to its normal position, being retracted by the spring 28, which acts against a collar on said shaft, and the pawl 10 will then rengage the outer ratchet 8, as before. The operator may return the platen 25 to the former starting position by pressing the treadl'e so as to pull the cord 27, whereby the drum 13 is rotated and the cable 20 wound on the same, which applies to the platen-carriage the force necessary to'move it to the right.

I will now describe the means for moving the platen 25 backward to a point in any space intermediate the numeral 5 and its multiples. As shown best in Figs. 3 and 4, a leverarm 30 is mounted loose on the shaft 6 and projects through a lateral slot in the cylinder. It is held normally at the top of said slot by a wire spring 31, suitably connected with it and the cylinder. A ratchet-disk 32 is fastened by a set-screw on the shaft 6, and a pawl 33 is pivoted to said lever and adapted to engage it, as shown in Fig. 4. A stud or pin 34 holds the pawl out of engagement when the lever 30 is raised; but when the latter is depressed the spring 35, which bears on the heel of the pawl 33, throws its point inward, and thus the ratchet 32 and shaft 6 are rota ted. It is apparent this will also rotate the drum 13 and wind on the cable 20, whereby the platen-carriage will be drawn to the right. Thus back spacing may be effectedthat is to say, suppose the platen to have been adjusted to the numeral 50, as before, and it be desired to move it back to 48 the lever 30 is twice depressed in order to rotate the ratchetdisk 32 the distance equivalent to two spaces or notches on the latter. In other words, the downward throw of the lever 30 turns the shaft 6 and drum 13 backward, and thereby pulls on the cable 20, which in turns draws the platen-carriage back one space.

I will now describe the means for effecting line-spacing, which is effected, as usual, by rotating the platen 25 the required distance. The platen is mounted slidably, but not rotatably, on a shaft 36, Fig. 8, having a ratchetdisk 37 fixed on its right-hand end, to which disk a rotative step-bystep motion is imparted by a lever 38 and spring-pawl 39 through the medium of a pull-cord 40, connected with a treadle, as will be hereinafter described. The shaft 36 does not slide, but

grooved throughout its length and afeather It, Fig. 11, attached to the extended hub 45 of the platen enters and slides in such groove. A sleeve -16 is interposed between the shaft 36 and hub .5 to take the friction and wear.

It will be apparent that if the operator moves the treadle so as to pull the cord 4:0 the lever 38 will be depressed and its pawl 39 caused to engage the ratchet 37, thereby tu rning the shaft 36 and platen 25 together, so that the lat terisadjusted as required for linespacing. The lever 38 is thrown up to its normal position by a spring 46, Fig. l. The said lever works in a keeper attached to bracket-flange ti.

I propose to employ any suitable treadle mechanism to operate the pull- cords 27 and 40. In Figs. 0 and 10 I show two treadles that may be advantageously employed. The pull-cords pass down through the table a7 and over idle pulleys 48 to lateral arms 49 of the respective treadles proper. Each of these latter is formed of a vertical shaft 50, set at its end on pivots attached, respectively, to the table and floor and provided with lateral footrests 51. Spiral springs are attached to the head of each post or shaft 50 for throwing it back to normal position. By applying a foot to each rest 51 the operator may rotate the shafts, and thus cause their arms 49 to pull the cords 27 40 when required to return the platen-carriage or to rotate the platen for spacing between the lines. The dotted lines, Fig. 9, illustrate the movements of the treadle mechanism so far as requisite to enable the operation to be understood. lVhen the platen has been returned by operating a treadle to pull-cord 27, its arm 'or check 52, Figs. 2 and 8, strikes a rubber buffer 53, attached to the machine-frame 2 by means of a supportingbracket 5%.

Recapitulating, spacing between the lines is effected by a treadle mechanism operating through the pull-cord 40 on the lever 38 and ratchet 37, whereby the shaft 86 and platen 25 are rotated. The operation of the other treadle draws the platen back to starting position, and the hand or thumb lever 30, ratchet 37, and shaft 36 serve to bring the platen back one or two spaces.
