Specification of Letters Patent. v]a,;q33ed Api. 19, 1910. 4

Application led February 25, 1910. Serial No. 545,831.

borough of Brooklyn, county of Kings, and

State of New York, have invented a.. new and useful Improvement in Linotype-Machines, of which the following is a v specification.

My invention has reference to line cast! ing machines, whereinprinting bars or slugs having type characters. on the edge are formed in a slotted-mold from which -they5 are ejected between twoparallel trimming knives into a receiving galley, as illustrated, for example, in' Letters Patent of the United States No. 436,532.

The invention has specific reference to machines in which one knife is adjustable toward and from the other in Order totrim the slugs to one thickness or another as demanded, and in which the slugs are delivered successively from the knives to an inclined galley, as represented in Letters Patent of the United States No. 884,022 to Kennedy. In these machines the slugs received upon-the galley are pushed one after another to the left,the accumulated series of slugs being moved forward in the galley each time that a slug is added tothe end. As heretofore constructed the mechanism did not continue to guide the slugs as they passed endwise into the galley, and it occasionally happened that the end -slug would vfall backward out of position and p rmit the succeeding slug to enter before i thus causing transposition of the slugs.

The present invention is designed to overcome this difficulty, and it consists broadly in combining with the adjustable knife a slug guiding member which extends forward over the galley and which is movable simultaneously with the knife, so that the passage for the slug is automatically varied in width according to the thickness of the slug, and the slugs consequentlyguided properly to the galley.

Referring to the drawings: Figure 'l is a perspective view of the movable knife and attendant arts, commonly known as' the Aknife bloc of the commercial Mergen- .thaler machine with my improvement applied thereto. Fig. 2 is a horizontal sec' tion through the two trimming knlves and adjacent parts in their operativerelation to the galley.

Referring to the drawings, A, represent .stantly to the right by a spring the upright, ,parallel knives between which the slugs are .delivered the usual manner.

C is the galley to which the slugs are delivered successively, the lowerends of" the lupri, 1 ;ht slugs being thrown forward so that in the manner fully explains 1n' the tends to separate the knives and is moved from the mold which forward step lby stepkto approximate the knives by means of screws or studs -I carried by a sector plate J. formed with a handle y', and turning-on a horizontal, fixed `pivot K. The screws I project different distances from the sector plate, vso that as the latter is turned about its pivot the different'screws coming successively into action against the `slide Gr will push 1t to theleft a greater or -less distance, "thusvaryin the distance be? tween the two knives A, so that-the out'- going slugs will be of greater or less thick-v ness as demanded. The outgoing slugs are guided beyond the knives between a vertical surface L on the frame and a plate M engaged at its forward edge with the knife B, and supported by a yielding spring m. After passing beyond the plate M the slugs are guided on the left-hand side by a plate N bolted to the frame. The parts so'far as Ik described are of the ordinary construction, and are not claimed as partof the present invention.

In applying my improvement I provide i a thin vertical plate or arm P and secure the same rmly to the left side of the knife carrying slide G, so that the outgoing slugs are guided between this arm P and the arm N as they pass upon the galley. Thearm P is Aextended forward above the upper surface of the galley for a suiiicient distance toA guide each of the outgoing slugs directly- ,to its place on thegalley at the right of the 1 preceding slug. As the knife B is adjusted toward and from its'companion the guide P is moved to correspond, and thus the passage Y through which the outgoing slug' is guided upon the galley is varied in Width to correspond with changes in thickness in the slugs, so that cach slug is Aguided to its proper position.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a line casting machine slu trimming knives, one of which is adjustable toward and from the other', in combination with a receiving galle and a slug guide extending from the knife to the galley and movable with the knife.

2. In a slug casting machine the combination of knives relatively adjustable to trim slugs of different thicknesses, a galley to receive the slugs from the knives, and intermediate guiding surfaces extending to the galley and automatically adjustable with' the knives to correspond with the distance between the knives.

3. In combination with a fixed knife A and stationary slugguiding surfaces beyond the same, a movable guide l movable therewith. j

4. In combination with fixed knife A and movable knife B, the inclined receiving gal ley C, the guide P movable with knife B, a pusher E to advance the successive slugs upon the galley, and a to support the slugs.

5. In a line casting machine a slug receiving galley, an adjustable slug trimming knife, and an intermediate slide extending to the galley and movable with the knife.

In testimony whereof I hereunto set my hand this 3rd day of February, presence of two att-esting witnesses.
