ToalZ whom it may concern:

1B8 it known that I, J osnrrr U. MEISTRELL, a: citizen of theUnited States, and residing at Brooklym'Kings county, New York State, have invented certain new and useful Improvements in Ejector Controls for Type- Bar Machines,of which the following. is a specification.

This invention relates to type-bar machines and more especially to the ejectors and blades for the sameand its object is to prevent'damage to blades and the machine in casethatjthe mold disk has been set for a bar of certain length and the operator forgets to set the blades for that length of bar, the. "devicewill automatically adjust the blades fora minimum lengthbar and reduce the range of the ejectorblade.

These andother objects of the invention are more fully described in the following specificatiom set fortlr in the appended claims and illustrated in the accompanying drawings, wherein: v a 1 Figure 1. is a perspective View of the device detached-from the 1 type bar machine,

Fig. 2 is a side view of the ejectorblade t o l vere dthe l tch, r

Fig. 3 is a plan view of the latch.

In the drawings, the machine is eliminated and only so many ofi the ordinary details are shown as may be needed to clearly illustrate and describe the operation of the invention. These few parts are the control lever 5, the ejector blade scale bar 6, the segment 7 and the mold disk pinion 8.

A lever 9, is fulcrumed to the frame of the machine below the vise and the mold disk by means of a clamp 10, and at a point which gives the end 11, a much greater throw than the end 12, the former end being ofl'set at about a right angle. 12, of the lever 9, is secured a rod 13, that connects it with one arm 14, of a bell crank lever which is pivoted by any desired means to theframe of the machine and adjacent the mold disk, and the other end 15 of this lever carries a roller 16, that stands in the path of the pinion 8, as it is shifted outward in setting the mold disk for a new length of bar.

When the pinion 8, is thus shifted outward, it depresses the end 12, of lever 9, and raises the end 11, which carries with it a rod having the reduced portion 18, which forms cam shoulder 19.

The lever 5 carries at its outer end a latch P ENT To the end or BROOKLYN; new YORK.

sliding plate 22, held on a base plate 23, by the head of a bolt 24, that playsin a slot 25, in the plate 22. The plate 22, is held in its extended position by aspring 26, connected with an arm 27,

21, consisting of a that causes two slots 28 and 29, onein'the engages the indents in the segment 7 and 1.

holds the lever 5, and thescale bar 6, in their proper position, but the aboveqdescribed-action of the pinion 8, thus releases the .plate, the latch and the'lever and scale, and the parts operated by theformer, reduce the blade operation to the minimum and cause the scale, to exhibit the ems that are inoperation; This is caused by thedrop ping of the rear .endmof lever 5, with the weight of-the parts it carries and the upward movement or the scale bar; when its lowest number is shown. l 4 j I If it is. necessary :to disengage the latch at any time, the plate-22,may be retracted by a trrggerSO, depending belowrthe platesand operatable when the ends of the latch are grasped.

The lever 9, is made in the shape of a yoke to conform with the parts of the machine, but it is obvious that the details of the device may be otherwise arranged or modified without departing from the essential features above described or from the scope of the appended claims.

In case the linotype operator is careless or distracted and sets his mold disk and forgets to shift the control lever for a corresponding ejector blade operation, it is liable to leave a long blade action for a short type bar mold which would seriously damage the blades and liners. The above described mechanism tilts lever 9, the instant the pinion 8, is drawn outward to rotate the disk and this operation withdraws the latch causing the rear end of lever 5, to drop and shift the blades to their minimum number and at the same time the bar 6, is shot upward and the number of ems is exhibited. This will necessitate the proper adjustment of the control lever to correspond with the line mold,

or if this is overlooked, the minimum blade mayoperate but do no damage.

7 What I claim as new is 7 1. In an ejector attachment, the comblnahav'ingan arm 'inthe'path of the pinion as tion of a shifting mold disk pinion, an ejector control lever having a latch, and inter-1 mediate connecting andoperating means between the leverand the mold disk pinion to release the latch when the pinion is shifted.

'2; In an ejector lattachmenu-the combination of a'mold disk pinion, an ejector zcontrol lever, alatch adapted to hold the levers-in .a

- 3 certain position, and a lever operated-by the 7 pinion, and connecting means between the lever and thelatch to release the latter."

' 3. In an ejector attachment, the combination :of a mold disk pinion, an ejector control lever, a latch adapted to lock said leverfa toothed segment, a lever operated by the pinion, and a second lever connected with the operated leverand adapted to withdraw the latch from the toothed segment.

l 4. In an ejector attachment, the combination of a mold disk pinion, an ejector control lever, a stationary toothed segment, a latch on the lever and adapted to engage the segment, a lever adapted to be actuated when 7 the pinion is shifted, and a rod carried at the outer end of a second lever that isactu- 'ated by the latter lever'and adapted to shift the latch andrelease the control lever.

5. In an ejector attachment,the,combina tion of a mold disk pinion, an ejector control lever having-a scalebar, a lever adapted to be operated by the pinionwhen it is shifted, a sliding latch with a perforation carried by the control lever, a toothed segment adapted I to be engaged by the latch,.and a bar with a cam shoulder carried at the end of the pinion operated lever and passing through the it shifts, a rod at the other arm of the lever,

a lever at the lower end of the rod and pivot ed to the frame, of a machine, 7 a lever adapted to shift a scale, a sliding plate on the lever and havingan opening, a rack 'segmentengaged by vthe plate tollock't'he lever, a rod with a cam shoulder carried and actuated by the lever that. is'pivoted to theframe and adapted to move upward anddisengage I the latch, and a trigger adapted to operate the latter independently. V j

7 In an ejector attachment the combination'of the ejector control means adapted to be held at a certain position,movablemolding means, an intermediate connectingmeans adapted to effect the'release of the ejector control means when the molding meansis actuated.

8. In an ejector attachment,the combinae tion ofthe ejector control means, a pinion adapted to be shifted with its shaft, molding means connected-with the p inionf a-lever operatingthe control means and adapted to be locked, and intermediate actuatingmeans operated-by the pinion when shifted to unlock the lever. i
