' LINOTYPE-MACHINE.

Specification of Letters Patent. Patented July 25, 1916.

Application filed November 30, 1912. Serial No. 734,362.

To all whom it may concern:

Be it known that I, EDWARD M. Gooneonr, a subject of the King of Great Britain, and a citizen of the Dominion of Canada, now residing at Brooklyn, in the county of Kings and State'of New York, have invented certain new and useful Improvements in Linotype Machines, of which the following is a specification.

The present invention relates to improvements in linotype machines and more particularly to the escapement mechanism which controls the delivery of matrices from the magazine.

The primary object of the invention is to provide spring means for restoring the escapements to normal position, such means being very compact, thus avoiding encroachment upon or interference with other parts of the machine, and the strength of the spring action upon all of the escapements will be uniform, the springs will not be liable to exceed their limit of elasticity, and also the spring means embodying the present invention is simple inconstruction, inexpensive to manufacture, and capable of being readily applied and removed.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particu larly in the claims at the end of the specification.

In the accompanying drawing :Figure 1 represents a vertical section of the lower or delivery end of the magazine of a linotype machine embodying the present invention; Fig. 2 is a bottom plan view of one ofthe lower corners of the magazine.

Similar parts are designated by the same reference characters in the several views.

The present invention is applicablegenorally to line composing and type castingmachines of the class embodying a magazine having channels or cells containing matrices andprovided with escapements controlling the delivery of the matrices from the respective channels, the invention being especially applicable to the escapement mechanism of linotype machines and may be used in connection with various forms of escapement mechanism.

In the present instance, the magazine 1 is of the usual or well-known construction, it having upper and lower grooves 2 which form channels or cells along Which the matrices M may gravitate toward the lower or delivery end of the'magazine, the latter being shown in the inclined position whiohit occupies on the machine. The lugs m of the matrices slide in the upper and lower grooves of the magazine as in the machines commonly used.

The invention is shown in the present instance as applied to escapement mechanism such as that disclosed and claimed in the co-pending application of Thomas S. Homans, Serial No. 707,926, filed July 5, 1912, although it is to be understood that the present invention is not restrictedto an escapement mechanism of this particular type.

The escapement mechanism to which the invention is applied in the present instance may be briefly described as embodying a bar or rail. 3 which is secured to the under side of the magazine, and the upper face of this bar is grooved to form uninterrupted continuations of the lower grooves in the magazine. The lower side of the bar or rail 3 is of substantially semi-cylindrical form and it is provided with a series of grooves l which are of semi-circular form. These grooves 1 converge toward the delivery end of the magazine and are preferably arranged directly below and in alinement with the converged matrix channels of the magazine. An escapement 5 is arranged to oscillate in each semi-circular groove 1, the es capement being substantially semi-circular in form and its ends 6 and 7 serve as dogs or pawls to cooperate with the lugs of the matrices in a manner to cause the delivery of one matrix from its respective magazine channel upon each actuation of the escape-- ment by manipulation of the keyboard, a series of reeds or key-rods 8 being provided vwhich are elevated from the full line posi- -mounted on a single or common rod 11, the

latter being supported by the rail 12 at the llllltBlI' strength and resilience than springs under side of the magazine and serves as a common pivot. One end of each lever is provided with an arm 13 upon which a spring 14 presses, and the other end of each lever has a portion 15 which cooperates with a lug or projection 16 on the respective escapement. Preferably, the spring-actuated" members operate in an'upward-direction upon the forward ends of theescapements,

this arrangement being advantageous in that the key rods or reeds Sand the springactuated members both act to retain the escapements in engagement with the semi-circular bearings provided'by the groove in the under side of the bar or rail 3, and also this arrangement of the spring-actuated mem- 7 here avoids interference with the operation rangement of the springs being very comepact and it enables the springs, and the actuating members to occupy the limited space between the .escapements and the mouth or delivery end of the magazine without encroaching upon the guides through which the matrices pass when they are delivered from the magazine.

Experience has demonstrated that-helical springs of round wire are more uniform in of any other form, and that amaximum degree of action can be obtained from springs of this typewithout'danger ofexceeding their limit of elasticity.

-The present invention provides compact, simple and inexpensivemeans for utilizing helical springs for the purpose of restoring the" magazine escapements to normal or initial position, and the chambers which inclose and guide these helical springsmay be readily formed by boring into the lower end of the rail12. The present invention also provides simple and improved means for preventing dropping of the escapements 5 from their bearings in thebar 3when the pressure of the reeds or key-rods 8 is relieved, such means consisting in the present Copies 01' this patent may be ontained for five cents each, by addressing the Washington, D. G."

operate with the semi-circular lower edges of the escapements. This'guard is preferably held in operative position by screws 19 'which are tapped into the bar 3, and the heads of these screws overlie the-longitudinal edges of the guard. ,This arrangement enables the guard 18 to be readily removed by sliding it longitudinally between the screws 19, removal of the screws being unnecessary, and when the. guard has been removed, all of the escapements can be readily removed for'cleaning or replacing.

While the matrix-containing channels of the magazine converge toward the mouth or delivery end of the magazine' and the escapements are preferably disposed in the same planes with their respectivechannels, the members which serve to transmit the action ofv the springs to the respective'escapements may be arranged in parallelism, as shown, thus simplifying the construction and reducing the cost of manufacture thereof. Y

I claim as my invention V 1. Ina linotype machine, the combination of a matrix-containing magazine, a semi-cylindrical bar having semi-circular grooves in its'under side, a series of matrix-controlling escapements mounted in the semi-circular grooves in said bar, and a guard detachably fitted to the outer surface of said bar and engaging the escapements to retain the escapements in place.

S2. The combination of a matrix magazine,

a bar arranged at the under side thereof, a set of substantially semi-circular matrixcontrolling escapements cooperative with the under side of said bar, and a guard slidable longitudinally of said bar and cooperative with the escapements to retain them in operative position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
