LINE-CASTING MACHINE.

Specification of Letters Patent.

Patented Nov, 9, 1-909.

Application filed April 17, 1909. Serial No. 490, .t48.'

casting machines in which circulating matrices are selected by finger-keys, assembled temporarily in lines which are presented successively to a mold to form type characters on the slugs cast therein, and thereafter returned to a magazine from which they were released.

The im rovements are intended more particularly tor embodiment in machines of the character represented in Letters Patent of the United States No.605,1-il,ltnown to commerce under the trademark Monoline. In these machines the justification of the composed lines is eitected by expansible spacers, each composed of two connected, oppositely tapered wedgeswhich are seated in the composed line between the matrices, one edge of each spacer having an ear which projects edgewise therefrom, to engage retaining devices by which the wedge is held down in the line while its companion is being raised to effect the elongation and justification of the line. After the casting action, the composed line is moved horizontally from the casting position in front of the mold to an elevating and distributing mechanism, by which the matrices in the line are separated and returned to the appropriate chan- Before the line reaches the elevator, a downwardly moving pressure device acts upon the upper end of the elevated wedges to push them down to their original positions, as is necessary in order that they may pass 'properl to the elevator. In practiceit occasiona ly happens that the pressure device isprevent-ed by the presence-oi metal chips or otherwise from descending the roper distance, and in consequence of this act, the wedges standing above the proper level are liable to come in contact with other parts of the machine, which results in breakage or injury.

The aim of my invention s to avoid this occurrence, and to this end consists in cominning with the so-called line delivery carriage, by which the composed lineis trans ferred horizontally, a means toprevent i s movement toward the elevator unless the ustifying wedges are first carried down to the proper level.

In its preferred form this device consists of a detent or lock controlled by the pressure device, and engaging the carriage to prevent the transfer of the matrices.

With the exception of the parts torming the subject of my invention, the machine may be in all respects like that represented in Patent 605,1 t1 oroi an similar commercial form. I have-there ore restricted the drawings herein to those parts with which my improvement is immediately associated.

Figure 1 is a front elevation showing a portion of the carriage detent and the pressure device by which the latter is actuated, the detent being in operative position. Fig. 2 is a top plan View of said parts. Fig. 3 is a vertical section on the line 3-3 of the preceding figures. Fig. l is a front elevation showing the manner in which the de- M tent is held out of action when the pressure device descends to the proper level.

In the drawing, 60 represents a horizontally movable line carriage, by which the composed line of matrices and justifiers is confined and moved horizontally from the composing position toward the left of the casting position, and thereafter to the right to the elevator and distributer. Itis mounted to move on the horizontal bar or support 89, and receives motion through a lever and cam, as usual.

117 represents a vertically movable pressure device, sometimes known as the'primary line depressor. It is a skeleton frame mounted to move vertically on guides in the main frame when the composed line, in its course to the distributer, stands thereunder, so that the matrices and justifier wedges will be forced down to the common level.

The foregoing parts may all be constructed.

and arranged to operate in the same manner as the parts indicated by like numerals 1n the patent above referred to.

- Passing nowto my improvement, A represents the detent or locking dog, connected to the main frame by a horizo zfqeal pivot, a, near one end, and having the opposite end formed with a lateral shoulder, 0 ada ted to engage a block, B, secured to the si e of the line carriage. i

The rear end of a dog it stands beneath the de ressor slide, in such position that if the sli e descends to the pro er level, it will act upon the dog and lift its forward end above the path of the block B on the line carriage, leavin the latter free to advance the line to the e evator and distributer; If, however, for any reason the depressor frame 117 fails to descend far enough to car the spacers and matrices downward to sue position that they will freely enter the elevator, the dog will remain in the normal position shown in Fi 1, so that as the carria%e moves to the rigit with the line it will e arrested by the dog, and the transfer of the line in improper position prevented.

Having thus described my invention, what E claim is: v

1. In. a machine of the class described, the

line carriage, means for depressing the matrices to a common level, and intermediate means for controlling the movements of the carriage.

2. In amachineof the class described, the

line carriage, a detent to control the movement of the carriage, and a matrix alining line carriage for transferring the composed line to the distributingmechanism, in combination with means for depressing the members of the lineto a common level, and means act-in normally to prevent the advance of the ine carriage toward the distributer whenever the depressor fails to properly aline the matrices.

In testimony whereof I hereunto set my hand this 9th-day of March, 1909, in the presence of two attesting witnesses.
