Application filed September 15, 1908. Serial No. 453,081.

To all whom it may concern:

Be it known that I, YILLIAM'JANSON ROCHE, citizen of the United States, and resident of New Bethlehem, in the county of seated in'anopening in the line spacing. I lever and at its otherend 11 bears against a Clarion and State of Pennsylvania, have inj vented certain new and useful Improve- I ments in Type-l fVriting Machines, of which the following a s ccification.

My invention re ates to ty-pewriting machines and more particularly to line spacing mechanisms therefor.

Onev of the objects of my invention is to provide simple and efficient mechanism which may readily be adjusted to vary the degree or extent of line spacing.

A further object of iny'invention is to actor of line spacing.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims,

In the accompanying drawings wherein like reference characters indicate correspond:

' therefor.

ing parts in the various views, Figure 1 is an enlarged detail fragmentary plan view showing a portion of a typewriting machine equipped with line spacing devices embodying my invention. Fig. 2 is a fragmentary end viewof the same. Fig. 3 is an enlarged detail fragmentary plan view showing a portion of the line spacing lever. Fig. 4 is an enlarged fragmentary detail sectional view taken on a line..r-r of Fig. 1 and looking the direction of the arrow at 'said line.

A cylindrical platen 1 is mounted in a platcn frame or carriage 2 which is mounted f in any suitable manner to travel from side to side of the machine. The platen provided at the right-hand end with a line spacing wheel 3 having teeth 4 on the outer edge or end thereof. A supporting member 5 is' se-, cured to the front rail of the carriage or platen frame and extends u wardly therefrom. This supporting mom or has a conporling member 5 is internally threaded for The pivotal portion of the sup- I ,the center. The line spaclng lever 13 propin .12 which projects upwardly from the front rail of the carriage or platen frame. This pin is' arranged in a cut-out or opening 13 in the line s acing lever and'cooperates with the end we 1 15 of said cut-out to'limit the movement ofthe line spacing lever in one direction under the tension of spring 9; The forward end of the line spacing lever isprovided with a finger piece or'handle 16, by which the line spacing lever may be given a horizontal swinging motion around its vertical pivot. A swinging movement of the finger piece 16 toward the right is effective to produce a line spacing movement ofthe automatically effect a change in the charplaten and at the same time'to effect a movement of the carriage from left to right as will hereinafter more clearly appear. line spacing pawl 17 is pivoted on a shouldered screw 18 entered in a tapped hole 1 8" in thementof the line spacing pawl relatively to the lever in one direction. A contractile spring 2] is connected at one end to a depending pin 22 on the line spacing pawl and at its other end to a depending pin 23 on the line spacing lever so as to normally maintain the line spacing pawl in a fixed position relatively to the line spacing lever. This normal position of the pawl relatively to the line spacing lever determines the extent of movement which is transmitted to. the line spacing wheel and platen. The means for determining this extent of line spacing movement comprises an arm 24 projecting from the pawl and having a depending p n 25 riveted thereto. This pin is adapted to play or work in a cut-out or opening 26 in the line spacing lever and to contact with the end wall 27 thereof, which wall constitutes one of the stops that determines the normal position of i the pawl relatively to the line spacing lever. tracted portion which enters an opening 6 1n a line spacing levcr 7 and constitutes a pivot F cooperation with a headed screw 8 by which the line spacing lever is retained in place on its pivot. A coiled spring 9 surrounds the supporting member 5 and at one end is;

From an inspection of Figs. land 3 it will be seen that the cut-out or openlng 26 is areshaped, of which the pivot 18 for the pawl 1s vided with upwardly projecting ears 2-8 which support a pivot for a plurality of levers '29 and 30. Each of these levers (two being shown in the present instance) has a hub 31 ' piece 32 or 33 which preferab y'bears an indieating numeral. These numerals are marked 34 and 35. The rear ends of these levers are likewise bent at right angles to the body portions thereof and extend so that the rear portion of the lever 30 overlaps and normally rests u on therear portion of ,thele'ver 29,

and so t at the rear portion of the lever 29 normally rests upon the lever 7. The extreme rear ends of these levers 29 and 30 are bent down to form stops 36 and 37 respectively which lie one in front of the other. These stops are adapted to move at substantially right angles to the plane of movement of the pawl and to project into the path of the arm 24 of the pawl and into the opening 26 in the line" spacing lever. A leaf spring 38 is riveted at 39 to the line spacing lever and is bifurcated to form two springterminal arms 40 and ,41 respectively which bear against the undersides of the levers 30 and 29 respectively forward of the pivot thereof so as to normally maintain the levers in the position shown in the drawings where the stops thereon are interposed in the path of thexline spacin pawl. I

In t e use of the device, if the operator should desire to effect a single line spacing movement of the platen, that is to say, a line spacing movement of the platen at each actuation which corresponds to the distance between two adjacent teeth of the line spac-J ing wheel, then the operator will simply grasp the finger piece 16 and move it to the right which will cause the point of the pawl to engage the ratchet wheel and turn the platen one tooth space.

If the operator should desire to effect a double line spacing movement, then the finger piece of the lever .30 carrying the index 2 should first be depressed to remove the stop 37 out of the path of the line spacing pawl (or the arm 24 carried thereby) so that the pawl will normally assume a different relation to the line spacing lever; that is to say, the pawl will be moved forwardly around its pivot 18 until the arm 24 contacts with the stops 36. As soon as the fingerpiece 33 of the lever 30' is depressed and its associated stop 37 removed from the path 'of the arm 24 on the pawl, said arm will pass beneath the stop 37 and prevent its return to normal po sition; so that a .mere depression of the finger iece 33 is sufficient to move the stop 37 to inoperative position and to maintain it in such. position. Theo erator may then rasp the. finger piece 16 o the line spacing ever and move it to the right, which will effect the requisite double line spacing of the platen.v The act of moving the lever 7 is effective first to turn the pawl and lever together as one part until the nose of the I awl engages one of the teeth ofthe line spac1n ratchet wheel. A further movement of the lever effects an independent movement between the line spacing pawland lever and causes the line spacing wheel to be rotated.

fixed stop 42 on the carriage. The line spacing pawl always arrives at the same point at the termination of the line spacing movcment whether the parts he set for single, double or triple spacing, and the throw of the line s acing lever is always the same whether tie parts beset for single, double or triple spacing. The first portion of the qindependent movement between the line spacing pawl and lever is effective to remove the arm-24from beneath the stop 37 and the spring 40 is then effective to turn the lever 30 on its pivot, thereby again inter-posing the stop 37 in the path of the arm 24 on the line spacing pawl. The act therefore of line spacing is effective to automatically restore the stop 37 to normal position, thus again automatically setting the parts for single spacing. Should the operator desire to use double spacing continuously this may be done by turning a pivoted catch or locking device 43 on its pivot 44 so that the catch will overlie the forward end of the depressed stop lever 30, thus locking the forward end of 1t down against the tension of its spring 40, thereby permanently locking the stop 37 in the inoperative position.

Should the operator desire to provide triple spacing it is merely necessary to depress the finger piece of the sto lever 29 carrying the index mark 3. This movement of the stop lever 29 is-eilectivc to elevate the stop 36 in. order to carry it out of the path of the arm 24 on the line spacing pawl and also to carry the stop 37 with it to the inopcrative position. he spring 37 immediately turns the pawl on its pivot 18 until it is arrested by the contact of the pin 25 with the stop 27 formed by the end wall of the cutout 26 in the line spacing lever. The arrest of the awl in this position brings the arm 24 beneati the stop 36 and temporarily p rel vents the stops 36 and 37 from resuming their normal positions. The first actuation of the line space lever 7 is effective to withdraw the arm 24 from beneath the stops 36 and 37 and they will be forced. back to normal position by their springs 41 and 40 respectively. Should the operator desire to set the parts so as to continuously use triple spacing it is merely necessary to depress the finger piece 32 andturn the locking device 43 around its pivot so as to overlie the forward end of the lever 29, thereby locking the forward 'end depressed and permanently maintaining the stops 36 and 37 out of the. path of the arm 24. The line spacing pawl This move -1nent continues until the pawl engages a understood that the extent of independent movement between the line spacing pawl and its actuator or line spacing lever determines theextent of line spacing movement transmitted to the platen; and that, this maybe readily changed by an actuation of the stop levers or regulators whose finger pieces are associated with the finger piece 16 of the line s acing lever in such a manner that the hand 0? the operator applied to the finger piece 16 may also be used to actuate either of the sto levers.

t will be seen that by my invention I am enabled to readily change from one character of line spacing to another and to automatically restore the devicesso as to change back to the original line spacing if desired or to effect any given character of line spacing.

Thedevices of my invention maybe found to be particularly efficient where the work is of such a character that it is necessary to rapidly change from one character of line spacing to another.

Various changes may be made without departing from the spirit and scope of my invention.

What I claim as new and desire to secure.
