Application filed May 17, 1909. Serial No. 496,483.

To all whom it may concern:

Be it known that I, CLIO B. YAw, a citlzen of the United States, and resident of Arlington, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in T pe- VVritin Machines, of which the following is a specification.

My invention relates especially to line spacing devices for typewrlting machines and has for its main object to provide improved devices of the class specified.

Another object of the invention is to provide a construction in which, liability of the platen to overthrow is greatly lessened.

Another object is to arrange most of the line spacing devices within the platen and concentric therewith so as to lessen ;vibration and noise and to increase the manifolding power as well as to 'cover and protect the line spacing devices and avoid llability to injury or disarrangement of the parts. To the above and other ends the invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out inthe claims.

In the drawings, Figure 1 is a fragmen tary front elevatlonof a platen and platen carrier embodying my invention: Fig. -2 is a central horizontal longitudinal sectional view of the left-hand end portion of the platen. Fig. 3 is a central horizontal longi tudinal sectlonal view of the right-hand end portion of the platen. Figs. 4, 5 and 6 are perspective views of different elements of the line spacing mechanism. Fig. 7 is a face view of one of the elements of the line Referring first to Figs. 1 to 3, the platen frame or carrier comprises end bars 1 and 2. The platen is arranged between the end bars and comprises a sheath or cover 3 of a rubber composition or the like and an outer shell, core-piece or tubef4 which may be of metal and-which provides afoundation for and carries the sheath 3. Within the outer shell 4 is an inner shellor tube 5, these two shells being normally connected together as,

presently to be described'but being adapted to be dlsconnected at will to release or free the platen from the line'spa'cing devices.

Arranged for the most part within the right-hand end of the shell 5 and. fixedly connected therewith by screws 6 is an anwith said slot 19. The member nulus 7 provided with an inner 'flange' 8. The annulus bears upon and is supported by a member9 which is secured by screws 10 to the right-hand platen head 11' and forms in effect part of said platen head which is suitably secured to the right-hand end of the shell 4. The annulus 7. isheld from rightward movement relatively to said platen head by a plate or disk 12 which is secured to the member 9 by screws 13. The member 9 is provided with a rightwardly extending hub portion 14 which extends into and bears against the end bar 1. A washer 15 surrounds the hub 14 to the left of the end bar 1 and cooperates with a shoulder on said hub tov prevent relative movement between hub and platen frame. The hub l4 and the member. 9 are formed with a bearing opening which receives a shaft or spindle 16, said spindle projecting outside the end bar 1 and carrying a finger wheel 17 which is secured in place by a set screw 18. r v

The member 9 is formed with a narrow slot 19 near its center and with two diametrically opposite wider slots 20 connecting 9 terminates at its left in a reduced portion 21 which is provided with external threads 22. Atube 23 internally threaded at its right-hand end screws on to the 9 and in eflect member. is closed by a screw cap 24. The spindle 16 passes leftward through the member 9 and portion 21 and the member operates as a part of said The left-hand end of the tube 23 Specification of Letters Patent. Patented July 26, 1910.

its extension 21 as well as through the tube I .23 and its cap 24, bearing in said cap and terminating outside the same and within the shell 5. The left-hand end portion of said spindle carries a support or carrier 25 for a pair of rolls- 26. Said rolls are adapted to cooperate with the inclined inner ends of a pair-of grippers 27. The right-hand end portions of said grippers are seated inthe slots 20 and are notched at 28 to provide jaws which embrace the flange 8. Sad gri pers are also provided with rounded bearing portions 29 which cooperate'with the body vof the member 9. i

The rolls 26 are pressed constantly rightward by a coiled spring 30 which is housed within the tube 23 and bears at one end against the cap 24 and at the other end against a. washer 31 which is held from rightward movement along the. spindle 16 by a cross pin 32. The action of thespring normally causes the rolls 26 to force the inner ends of the grippers 27 apart, causin the gripping jaws to grip the flange 8 an thereby connect the shell 5 with the outer shell 4, so as to cause the two parts to rotate together. \Yhen the finger wheel 17 is pressed inward toward the left it causes a left-ward longitudinal movement of the spindle 16 in its bearings, thereby moving the carrier 25 leftward and causing the rolls 26 to move toward the ends of the grippers 27. The pressure tending to force apart the inner ends of the grippers is thereby relaxed and theflange 8 is freed from the control of said grippers so that the platen proper, comprising the sheath 3 and the shell 4, may be turned independently of the inner shell 5. As hereinafter described said inner shell car- 'ries the line spacing ratchet wheel so that wheel and the platen being efi'ected through a cross arm or plate 16 which isdriven through the spindle 16 and engages the sides of the slot 19. The platen releasing mechanism above described resembles in principle that disclosed in the patent to Woodward N 0. 784,369, dated March 7th, 1905, although difiering therefrom in some details.

Fixed within the left-hand end of the shell 4 is an annulus or bearingring 33 which surrounds and bears on the left-hand end portion of the inner shell 5. Said inner shell 5 extends outside the platen proper at the left. Arranged at the leftend of said shell 5 is a line spacing ratchet wheel 34;"

i the teeth whereof cotiperate with a roller detent 35 mounted on a spring arm 36 suitably secured to the platen carrier. The ratchet wheel 34 is part of a member or element which is shown detached in Fig. 4 and in section in Fig. 2. Said member comprises a reduced portion or hub 37 which fits closely within the left end of the-shell 5 and is fixedly connected therewith by screws 38. Ex-- tending from the opposite or left face of the ratchet wheel 34 is a hub portion 39 which bears in a depression or counterbore 40 in the end bar 2 and is formed with a central ceives the hub 42 of a member which further comprises a flange portion 43 and a closed at tubular portion 44. Screws 45 pass through tube 44 provides a bearing for the righthand, end of a spindle 46 which extends leftward through the tube 44, hub 42, tube 41 and end bar 2, terminating outside the platen frame where it is provided with a finger wheel 47 which is secured in place by a screw 48.

\Vithin the tube 41 the spindle 46 carries a clutch member 49 which is fixed to the spindle as by a cross pin 50. Surrounding the spindle 46 and confined between the clutch member 49 and the inner end of the tube 44 is a coiled spring 51 which, acting against the clutch member, tends constantly to force it and the spindle 46 leftward. Passing through the clutch member and the spindle 46 and projecting outside'said clutch member49 at diametrically opposite sides, is an engaging or connecting device or cross pin 52 (Figs. 2 and 6). The projecting end portions of said cross pin engage in parallel slots or cut-outs 53 extending longitudinally through the tube 41. The construction is such that relative endwise movement between the spindle 46 and the tube 41 may take place but by reason of the connection 53 said tube 41 is forced to turn whenever the spindle 46 is turned. Consequently a rotary movement communicated to the spindle 46 will be transmitted through the tube 41 to the ratchet wheel 34 and shell 5, and since said shell 5 is normally connected by the grippers 27 with the platen proper, the latter will ordinarily participate in rotary movements communicated to said spindle 46. The spindle 46 may be turned by turning the finger wheel 47 or through line spacing devices embodied in the present case.

The left-hand face of the clutch member 49 is provided with ratchet teeth 54, said ratchet teeth being adapted to co-act with corresponding ratchet teeth 55 formed on a flange or enlargement at the right-hand end of a cam member, sleeve or turning device 56 (Figs. 2 and 7). .Said cam member 56 is in the form of a cylinder extending leftward loosely through the opening 39 and through a bearing opening in the end bar 2. The spindle 46 passes through a central opening in said cam member, which also may be said to be supported in part on said spindle.

The ratchets 54 and 55 are normally maintained separated by a coiled spring 57, said spring surrounding the spindle 46 and being seated in a depression or countersink 58 in the clutch member 49 and a corresponding opposite depression 56 in the cam member 56. The spring 57 is somewhat weaker than the spring 51. Cut in the outer face of the cam member 56 is a cam slot 59 which may have a gradual pitch; say, proportional to one complete turn in 7% inches of length.

Engaging in the slot 59 is a stud 60 fixed in the end bar 2. Said stud is only slightly less in diameter than the slot 59 so that while it permits free movement of the cam member 56 lengthwise there is nevertheless little or no lost motion possible of said cam member in the direction of rotation. Obviously when the cam member 56 is moved endwise it will receive a rotary movement because of the co-action between the cam slot 59 and the stud 60. If at this time the ratchets or clutch devices 54 and 55 are in engagement, such rotary movement will be communicated to the platen and said platen will be turned in line spacing direction.

Surrounding the spindle 46 at the left of the cam member 56 is a washer 61 (Figs. 1 and 2) which aflords a connection between the end of the cam member 56 and a sleeve 62 mounted" on the spindle 46 between the Washer 61 and the hub of the member 47. The actuating movements of the sleeve 62 are controlled by a lever 63 shown in Figs. 1 and 2. Said lever has an open portion 64 which loosely embraces the sleeve 62 and is pivotally connected therewith by shouldered screws 65 which screw into the opposite sides of the portion 64 and are provided with reduced cylindrical end portions which engage in diametrically opposite openings 66 in the sides of the sleeve 62. Above the sleeve the lever 63 is shaped to provide a finger piece 63 or actuating handle. At its lower end the lever 63 is pivotally connected at 67 to a link 68 which is horizontally disposed and is pivotally connected at its opposite end at 69 to a lug 70 extending laterally from the end bar 2 of the platen frame. When the finger piece 63 is pushed rightward it causes the sleeve 62 to engage the washer 61 and through it the cam member or sleeve 56 and to force the latter rightward, compressing the spring 57 betweenthe ratchets 54 and 55. Thereafter as rightward movement of the finger piece is continued the spindle 46 will nove rightward and will also participate in the rotary movement communicated to the cam member 56 from the cam 59 and stud60.

The rotary movement of the spindle as has been explained will be communicated to the platen, causing the platen to be advanced in line spacing direction. The extent to which the platen may be turned will depend upon the rightward movement communicated to the sleeve 56 and the handle 63. The extent of movement of the cam member 56 may be varied at pleasure by a line space regulating device which is shown detached in Fig. 5 and also appears in Figs. 1 and 2. Saiddevice, designated as a whole as 71, is

- in the form of a sleeve which is mounted to turn with and on the tube 41 and is confined between the flange 43 and the hub 37. The sleeve 71 may be cut out in steps at its leftand causing an engagement hand end to provide a plurality of pairs of diametrically opposite stop faces. There are three pairs of these stop faces shown and numbered respectively 72, 73 and 74 corresponding to three different extents of line space movement, although, of course, a greater or less number of pairs of stop faces may be provided. These pairs of stop faces are adapted to close the slot-ways 53 in the tube 41 and thereby limit the movement of the cross pin 52 rightward in said slot-ways. For example, as shown in Fig. 2, the stop faces 73 are arranged to co-act with the cross pin 52. Hence the movement of said cross pin, and consequently of the cam member 56 rightward, will be arrested after the cam member has turned far enough to advance the platen two units of line space distance, corresponding to two teeth of the ratchet wheel 34. WV hen the stop faces 74 are operated, the rightward movement of the cam member 56 will be greater and the platen will be advanced three units of line space distance; while when the stop faces 72 are in operation, the platen will be turned through a single line space.

The means for turning the sleeve 71 on its support to present at pleasure one or another of the pairs or sets of stop faces, comprises a finger piece 75 which projects radially out ward through an opening or cut-out 76 in the shell 5. The finger piece 75 is provided with an extension 77 disposed at right angles to it and secured to the sleeve 71 by screws 78; That portion of the periphery of the hub 67 which is exposed by the cutout 76 and is opposite the finger piece 75 is or may be provided with indicating marks or numerals as shown in Fig. 1,.and the finger piece 75 cotiperates with these numerals to indicate the extent of line spacing movement. When the finger piece is moved lengthwise oft-he slot or cut-away 76 it will be understood that it turns the sleeve 71 on its support. The sleeve may be maintained set in one of the three line spacing positions by detent devices which comprise a ball 79 arranged in a hole 80 in the sleeve 71 and maintained in said opening by a spring finger 81 which issecured to the sleeve 71 by screws 82. The spring finger has a rounded depression 83 which forms ashallow seat for the ball 79; and said ball is further adapted to engage with depressions or seats 84, 85 and-86 formed in the surface of the sleeve 41 and connected by shallow grooves 87 (Fig. 4). It will be understood that the ball 79 will be maintained by the pressure of the spring-plate '81 in engagement with one or another of the depressions 84, 85 or 86 and that these depressions are arranged at such a distance apart that they permit a turning and setting of the sleeve 71 to bring the respective stop faces 72, 73 and 74 into operative position. After being set, the

25 of theeclutch member 49the cam member 56 gagement between the ratchets 54 and 55 so that the cam member 56 picks up the spindle 46 and moves it longitudinallyrightward and causes it to turn. The rightward movement of the spindle compresses the spring a 51. After the line spacing has been effected and the spindle 46, cam member 56 and line spacing handle have been arrested by the coaction between the cross pin. 52 and one of the pairs of stop faces on the sleeve 71, the line spacing handle may be released. Thereupon the spindle 46, clutch member 49 and cam member 56, together With the washer 61, sleeve 62 and line spacing lever 63, will be restored toward the left by the spring 51. The leftward return movement of the spindle 46 and clutch member 49 will be limited by the engagement of the end portions of the cross pin 52 with the left-hand face of the flange of the hub 37. After the arrest will continue to move leftward under the influence of the spring 57 until the rounded surface which connects the enlarged end of the cam member with the body portion thereof engages with the right-hand edge of the opening 39*, The spring 57 is weaker than the detent spring arm 36 so that prior to the complete separation of the ratchet teeth 54, 55 during the return movement, the reverse rotary movement of the cam member 56 will not turn the clutch member 49 but will simply cause the ratchet teeth 55 to slide over the ratchet teeth 54.

During the turning of the spindle 46 as it moves inward, the sleeve/ 62 will not be affected since it is loosely mounted on the ward movement of the sleeve 62 the pivotal point 67 will swing downward upon the pivotal center 69 so that there will'be no bind of the line space lever 63 on the sleeve 62.

It will be understood that the rightward movement of the finger piece 63 is adapted not only to effect a hne spacing of the platen but also a restoring movement of the platen and platen carrier from left to right to begin a newline of writing. The bodily rightward movement of the platen and platen carrier will ordinarily take place prior to the line spacing operation but both the restoring movement and the line spacing movement will be effected by what is practically a single operation of the line spacing handle. It will further be noted that most of the parts that comprise the line spacing mechanlsm are contained within the platen which covers and protects them from injury and accidental disarrangement. Further,

they are close to the axis on which the platen is supported and therefore cause much less vibration than do the ordinary line spacing devices. Consequently the stability of the platen and its manifolding power are increased.
