TYPOGRAPHICAL COMPOSING AND LINE CASTING MACHINE Filed Aug. 9. 1930 Patented Aug. 2, 1932 UNITED STATES PATENT UFFICE TYPE COMPANY,

OF BROOKLYN, NEW YORK, A COMPANY OF NEW YORK' TYPOGRAPHICAL COMPOSING AND LINE CASTING MACHINE Application filed August 9, 1930, Serial No. 474,133, and in Germany February 12, 1930.

This invention relates to typographical composing and line casting machines of the known construction in which matrices are released from a magazine by the depression 5 of keys which, together with certain of the members which transmit the movement onward from the keys, are located in a keyboard. In order to make this keyboard more easily accessible, and more especially those parts thereof located at the back, it has already been proposed to movably mount the keyboard on pivots so as to permit it to be swung out of its operative position. This arrangement necessitates a comparatively complicated mechanism for the keyboard parts, more especially for the making and breaking of the connections between the keyboard and the escapement bars effecting the release.

to The present invention aims at obtaining the same results with much simpler means.

According to said invention, the keyboard as a whole, is laterally movable, and is so mounted that it can be moved sideways a definite distance. When so moved and while still remaining in the machine, it will be conveniently accessible both from the front and the rear, in order topermit the necessary inspection to be made and defects to be remedied.

The drawing illustrates by way of example, and more or less diagrammatically, one constructional form of the invention, and in this drawing:

Figure 1 is a side elevation as seen from the right of the machine, and showing only the pertinent parts of the latter, and

Figure 2 is a front elevation of Figure 1.

The keyboard a is mounted so as to be laterally movable in a fixed guide I). This guide I), as shown more particularly in Figure 1, has a T-shaped groove or opening in which run the projections, rollers or the like b mounted on the keyboard. As a consequence of this arrangement, the keyboard can be moved rightward from the position in which it is shown in full lines in Figure 2 into the position in which it is in part shown in dotted lines in that figure. In order to ensure or retain the proper engagement between the magazine and the escapement rods 0, which latter, when a key is depressed, are raised by the cam yokes e, the saidrods are suspended at their upper ends on a wire 03 which, as has already been proposed, traverse corresponding slots in the upper endsof the escapement rods 0, said wire itself being mounted on the machine frame. The lower extremities of the escapement rods 0, therefore hang freely over the cam yokes e. A comb or the like 7 is provided for guiding the lower ends of the escapement rods 0, this comb being secured to the machine frame by two depending arms or stays g. The brackets h, which are attached to the keyboard and serve to support the well-known rubber covered rollers i, are formed, at least those at the lefthand side, with a gap or recess 70, so that when the keyboard is moved from one to the other of the two positions shown in Figure 2,

, the lower ends of the escapement rods owill be cleared and remain undisturbed.

Obviously, the present arrangement could be constructed otherwise than as illustrated in the drawing, for example, instead of the guiding groove'being of T-shape, it may be of dovetail form or a guide provided with rollers could be employed; or again said guide, instead of being immediately below the keyboard, could be located elsewhere.

Having described my invention, I declare that what I claim and desire to secure by Let-' ters Patent is: V I k 1. In a typographical composing and line casting machine, the combination of escape- 8.5 ment actuating rods, keyboard mechanism comprising cam carriages acting upon said rods, a frame supporting the keyboard mechanism and a stationary guide mounted'in the machine frame and in which the frame is A movable to bring the cam carriages into and out of operative register with the escapement rods, said guide being arranged to position the keyboard mechanism clear of the machine frame when the keyboard frame is moved to its inoperative position.

2. In a typographical composing and hue casting machine, the combination of escapement actuating rods, keyboard mechanism comprising cam carriages acting directly upon said rods, a frame supporting the keyboard mechanism and a stationary guide in which the frame is movable to bring the cam carriages into and out of operative register I with theescapement rods. I

3. In a typographical composing and line casting machine, the combination of escapement actuating rods, a frame movably supporting those rods, keyboard mechanism comprising cam carriages acting upon the rods and a frame supporting the keyboard mechanism, movable laterally of the machine to bring the cam carriages into and out of operative register with the escapement rods. 4. In a typographical composing and line casting machine the combination of escapement actuating rods, a frame movably supporting those rods, keyboard mechanism comprising cam carriages acting upon the rods, a frame supporting the keyboard mechanism, and a stationary guide in which the last- Ilamed frame is movable laterally of the machine to bring the cam carriages into and out of operative register with the escapement rods.

- 5. In a typographical composing and line castin machine the combination of escapement actuating rods, a frame movably supporting those rods, keyboard mechanism comprising cam carriages acting upon the rods,

. a frame supporting the keyboard mechanism,

and a stationary guide in which the lastnamed frame is movable rectilinearly to bring the cam carriages into and out of operative register with the escapement rods.

6. In a typographical composing and line casting machine, the combination of escapement actuating rods, a frame movably supporting those rods, keyboard mechanism com prising cam carriages adapted to contact with the lower ends of the rods, a frame supporting the keyboard mechanism and a stationary guide in which the last-named frame is movable laterally of the machine to bring the cam carriages into and out of operative register with the escapement rods.

7. In a typographical composing and line casting machine the combination of escapement actuating rods, a frame in which said rods are movably supporting, keyboard mechanism comprising cam carriages adapted to contact with the lower ends of the rods, a frame supporting the keyboard mechanism, a stationary guide in which the keyboard frame is movable laterally of the machine to nature hereto.
