SPECIFICATION forming part of Letters Patent No. 739,591, dated September 22, 1908.

Application ned rune 15, 190s. serial no. 161,454.A (No model.)

To all whom it may concern:

Beit known that I, JOHN LYNN EBAUGH, of New Orleans, parish of Orleans, and State of Louisiana, have invented a new and useful Improvement in Linotype-Machines,of which the following is a specification.

My invention relates to the Mergenthaler linetype-machine represented as toits general construction in Letters Patent of the United States N os. 436,532 and 557,000. In

this machine the slug or linotype is cast in a slotted mold which is presented in front of an ejector-blade which advances through the meld, expelling the slug therefrom and driving it between two parallel knives, which serve to remove any burs or fins and to dress the slug to au exactly uniform thickness. The slugs are in a heated condition as they pass to the knives, and in practice it is found that the chips or shavings removed by the knives adhere somewhat tenaciously to their edges. It is necessary that these chips or shavings should be removed in order that they may not aiect theproper action of the knives or become attached to the faces of the succeeding slugs. For this purpose it has been customary to employ wiping devices arranged to travel lengthwise over the edges of the knives after the passage of each slug. Itis to these knife-wiping devices that the present invention relates; and it consists in a peculiar form and arrangement of the parts, hereinafter described, designed to overcome the minor difficulties heretofore experienced.

In the accompanying drawings I have represented onlymy device and the parts immediately associated therewith. -The remainder of the machine will be of ordinary construction.

.Referring to therdrawings, Figure lis a front elevation. Fig. 2 is a side elevation of the parts viewed from the left. Fig. 3 is a crosssection on the correspondingly-numbered line of the preceding figures.

Referring to the drawings, A represents the stationary portion of the front of the main frame, commonly known as the visa-frame.

B B represent the stationary knives, having vertical parallel edges between which the 5e slug is ejected.

.bar D to a hook on the lever E'.

ing at its upper end the wiper-blade E, adapted to travel over the edgesnof the knives and remove the adhering chips or shavings. This bar D is jointed at its lower end to an angular lever E', mounted between its ends on a stud or pivot F, fixed to the main frame. This lever is continued downward and forward beyond the pivotal point and has its extremity located in the path of a lip or plate G, secured to the side of the vertical slide O. A spring H is extended from a hook ou the This spring tends to throw the part-s Dv E' into angular relations,and thereby to draw the arm D downward until the wiper-blade stands at the lower ends of theknives. This is the normal position of the parts. Y

When the elevator-slide C descends to present the matrices to the mold, its projection Gr presses the forward end of the lever F, causing its rear end to raise the arm D, and thereby cause the wiper to travel over the knives to their upper extremities. When the elevator-slide O rises to its normal position, the wiper again descends; The movements of the wiper occur at such times that there is no danger'of its being encountered by the outgoing slug. The arm D is guided in its vertical movement by the lever E and by a slotted guide-plate I, attached to the frame. The wiper is held forward toward the knives and in proper relation thereto by the spring previously mentioned.

The advantage of connecting the knifewiper with the elevator O, which presents the matrix-line to the mold, lies in the fact that it insures the movement of the wiper at the precise time required-that is to say, while the mold and ejector-blade are retracted from the knives, so that the wiper may pass be- Having described my invention, what I claim is- 1. In a linotype-machine, the a-rm D, provvided with a knife-wiper, in combination with triX-line is presented to the mold, and an intermediate connection for imparting motion from the elevator to the Wiper.

4. In combination with the Wiper-arm D, and its aetuating-1everE,a connecting-spring H, applied as shown, for the double purpose of depressing the Wiper and of urging the same toward the knives.

In testimony whereof I hereunto set my hand, this 4th day of June, 1903, in the presence of two attesting witnesses.

JOHN LYNN EBAUGH.
