Specification of Letters Patent.
Patented Apr. 5,
Application filed November 3, 1908. Serial No. 460,826.
To all whom it may concern:
Be it known that I, Joni 1%. Rooms, of the borough of Brooklyn, county of Kings, city and State of New York, have invented a new and useful Improvement in Linotype- Machines, of which the following is a specification.
My invention has reference to mechanism for actuating the matrix-releasing escapements of linotype machines, such as represented in Letters Patent of the United States #436,532, and for kindred purposes.
The object of the invention is to provide a mechanism in which finger-keys, offering very slight resistance and having but a short movement, may call into action powerdriven devices through which the escapements are positively and definitely actuated, although the finger-key may be released before the completion of the action.
in the drawings,Figures 1 to i are vertical cross-sections through a keyboard mechanism in accordance with my invention, the successive figures showing the parts in the different positions which they assume during one cycle of operation.
Referring to the drawings, A represents a frame which may be of any suitable construction adapted to sustain the operative parts.
B, B, are the upright reeds for actuating the escapenients, mounted to slide upward and downward in suitable guides in the frame. They are commonly mounted in two rows, and are connected at their upper ends with the escapements, one to each escapement, as usual.
C is a constantly rotating roll, preferably covered with rubber or other soft material, and mounted in a. central position in the frame.
D, D, are cams designed to act upon the lower ends of the respective reeds and lift them against the action of the springs l by which they are drawn downward when the cams cease their action. These cams will be arranged in two rows corresponding with the reeds and on opposite sides of the roll C.
Each of the cams is secured to the side of a wheel or disk F, which is flattened on one edge and mounted on the inner end of a lever G, supported by a central pivot g in the main-frame. Each lever is connected at its outer end to a spring H, which tends to throw the inner end of the lever, together with the roll i and cam D, away from the roll C to an inoperative position, as shown in Fig. l. The levers G on one side of the roll C are acted upon by vertical slides I, connected by intermediate levers J to Vertical slides K, which are in turn acted upon by finger-key levers L pivoted at Z. Under this arrangement, the depression of the key will have the eficct of actuating the lever G and lifting the wheel F into engagement with the roll C, the frictional engagement causing the wheel F to turn and rotate the cam so that the latter will act with a lifting effect beneath the reed, as shown in connection with the lever G in Fig. 2. This action will continue until the cam has passed out from under the reed, and until the flattened edge of the wheel F has reached the driving roll. it this point, the roll will disengage from the wheel, and the latter will be thrown downward with the cam to their original positions. lVhen this descent occurs, the wheel F will contact with the stationary rod or stop M, preferably covered with rubber or leather, whereby its descent is arrested and its further rotation prevented. Any other suitable means may be employed to prevent continued rotation of the wheel.
The wheels F, located on the opposite side of the driving roll, stand normally above its center, as shown in Fig. 1, and their carrying levers G are actuated each by a vertical slide 1 connected directly to a finger-key lever Z, as shown in Fig. a, so that when the key lever is actuated, the lever G will carry its wheel 1 downward into contact with the roll 0, as shown in Fig. 2, the wheel being rotated as in the previous example, by the frictional contact, so that its cam will act beneath and lift the reed. It will, of course, be understood that in a row or series of the key levers L the alternate levers are connected respectively to the slides I and K. it will be observed that in my mechan i ism the cam acts directly to actuate the reed, and that the rotation of the cam is effected by a distinct concentric wheel, which on gages the continuously driven roll, C.
ihe continued rotation of the parts causes the reed to be released, as in Fig. 8, so that it will fall to its original position, while the cam continues its rotation until the flat edge of its carrying wheel reaches the roll C,
whereupon it will disengage and be lifted to its original position by the spring. It will be observed that in tlns arrangement, the
reed-lifting cams act directly on the reeds, that the cams are mounted on movable pivots, and that the action of the driving roll upon the cam-carrying wheels compels the latter not only to rotate, but to maintain their operative positions until they have turned so far that the cam, which has performed its otlice, and the flattened edge of the wheel will be brought next to the driving roll.
It will be manifest that the cams, their carrying wheels and the levers for moving the wheels may be widely modified in form and arrangement without changing the principle of action, or passing beyond the 1 scope of the invention. The finger-key levers may be made in any suitable form and connected with the levers G, G, by any devices which impart mot-ion to the latter.
It is to be noted that under the arrangement shown, a single central roll serves to impart motion to the two rows or series of cams, it being unnecessary to use the second roll commonly used in keyboard mechanisms of this character, such as shown, for example, in Letters Patent of the United States #531,266. The use of a single roll is possible because the cams on opposite sides are located respectively above and below the center of the driving roll and all arranged to turn in the same direction when in action.
It is obvious, of course, that when the es eapement mechanism of the machine and its single row of reeds are to be employed, the second row of wheels and cams may be omitted. It is manifest that the cams may be modified in shape and formed integral with or secured to the carrying wheels as preferred, the only requirement being that the wheel and cam shall be of such form that they may receive motion from the roll and impart motion to the reed.
Having thus described my invention, 1 claim and desire to secure by Letters Patent,- l
1. In an escapement-operating mechanism, a continuously driven roll G and a recipro- 1 cating reed, in combination with a cam directly engaging the reed and a wheel for turning the same flattened on one edge, the wheel and cam being mounted concentrically on a movable support.
2. The combination of the continuously driven roll C and reed B, the reed-lifting cam D, the cam-rotating wheel F flattened on one edge, the wheel and cam being concentric, a movable support for the cam and 1 wheel, means for moving the wheel into con tact with the roll, and means for throwing the wheel away from the roll.
The combination of the continuously rotating roll C, reed B, cam D, wheel F, lever G. spring H, and means for moving the lever.
l. In a mechanism of the class described, the combination of a continuously driven roll and wheel having an eccentric periphery, a cam rotated thereby, a reed actuated by the cam, means for moving the wheel at will into contact with the roll, and spring connections for retracting the wheel from' the roll.
5. in combination with the continuously turning roll, lever G, and eccentric wheel mounted thereon, a cam carried by the wheel, a spring tending to retract the wheel from the roll, finger-key connections for moving the wheel into contact with the roll, and ncans for arresting the rotation of the wheel when retracted.
('5. In combination with a single continuously driven roll, two reed-actuating cams, and wheels located at opposite sides of the roll, and means for throwing the wheels into contact with the roll, said cams being constructed to rotate in the same direction when in action.
in testimony whereof I hereunto set my hand this twenty eighth day of October, 1908, in the presence of two attesting witnesses.
