Serial No. 663,156.

T 0 all whom it may concern Be it known that 1, DAVID S. KENNEDY, a citizen of the United States, of the borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Line-Casting Machines, of which the following is a specification.

This invention has reference to Mergenthaler machines and kindred type casting and composing machines, in which matrices or type representing the various characters, stored in a magazine, are released one at a time through the action of escapement devices controlled by finger keys.

My invention relates to mechanism in which a single finger key is arranged to control the means for releasing matrices from two channels alternatelyboth channels carrying ordinarily matrices for the same character. I

The object of the invention is to permit the use of a large number of matrices of those few characters which are required with great frequency.

with the finger key of an automatic vibratory dog or latch which serves to communicate motion from the key to two reeds alternately, these reeds acting either directly or through intermediate mechanism on the respective escapement devices.

I have shown my invention as applied to mechanism of the well known Mergenthaler type now in commercial use. With the ex ception of the parts herein shown the machine may be in all respects of any ordinary or suitable construction.

Referring to the drawings: Figure 1 is an outline perspective view showing the mouth of the magazine, two escapements, and their 7 controlling devices, in accordance with my invention. Fig. 2 is a rear elevation showing the dog or latch in the opposite position from that shown in Fig. 1. Fig. 3 is a vertical section on the line 33 of Fig. 2. Figs. 1 and 2 are views showing the different positions the dog assumes in the course of its action.

In the drawings, A. represents an inclined longitudinally channeled magazine in which the matrices, B, B, are stored.

C, C represent the escapements controlling the delivery of the matrices, each consisting of a centrally pivoted lever carrying at opposite ends two upright pawls or dogs, which are projected alternately into the magazine-the lower pawl standing normally in an elevated position, to retain the foremost matrix.

D, D are vertically guided reeds acting at their upper ends on the respective escapements.

E, E are vertically movable cam yokes, pivoted at one end, and acting beneath the respective reeds D, D, to lift them.

F, F are cams mounted in the respective yokes and overlying the continuously rotating rolls G and G, being normally out of contact therewith.

H, H are two dogs pivoted to the main frame and serving to hold the inner ends of the yokes normally in an elevated position,

to prevent the contact of the cams with the driving rolls.

I, I are pins by which the cams, heavier on one side of the center than on the other, are prevented from turning downward prematurely.

J J are vertically guided" bars receiving motion from a finger key K, and serving to actuate the dogs, H, H and permit the fall of the yokes and cams, so that the latter may receive motion, one at a time, from the rolls, the effect of the rotation being to lift the reeds and actuate the escapements.

So far as described, with the exception of the connection between the finger keys and the bars J, J, the parts may all be constructed and arranged to operate in the manner set forth in Letters Patent of the United tates No. 530,931.

In the mechanism as heretofore constructed there was a finger key for each of the bars J, J; in other words, a finger key for each escapement. In carrying my invention into effect, and in order to operate two escapements alternately from the one key, I provide the rear end of the key with a dog or latch L. This dog is constructed with a transverse slot Z, with the two shoulders Z and Z on opposite sides, above the slot, and with the pointed lower end Z It is mount ed on a journal or pivot 70, on the rear end of the finger key, so that it may rock thereon and also shift bodily to the right and left. Beneath the finger key, on the main frame, I secure a beveled or pointed block M, in posi- .tion to encounter the dog L when the latter descends. On the bars J and J I form the lips j and j, to engage the dog L.

The operation of the parts is as follows: Assume the finger key to be at rest and the .dog L in its lowermost position, with its lower end resting on the left side of the i block M, as shown in Fig. 1. When the key weight of the bar on the shoulder j, to the left of the pivot on which the dog is mounted, causes the dog to slide or shift laterally at its lower end toward the right, as shown in Fig. 2 so that its lower end overlies the right side of the block M. As it completes its downward movement the pivot, actingin the slot, in combination with the block M, shifts the .dog bodily,.to the right, as indicated by dotted lines in Fig. 2; so that when the dog is next lifted, by the second action of the finger key, its right hand shoulder will engage under the bar J, which will be lifted, While the bar J remains at rest. In this manner,- by the joint action of the shoulders,

matrices delivered alternately from two channels ofthe magazine.

While it is preferred to operate the escapement through the intermediate cams and rolls, it is to be understood that these interf mediate parts may be omitted, and the slides J and J continued directly upward to the escapements, which latter will then receive motion directly from the finger key.

The essence of the invention lies in a latch carried by the fingerkey and vibrated automatically so that it may actuate the slides or reeds alternately.

While the invention is intended more par- Copies of this patent may be obtained for five cents each, by addressing 7 Washington, D. G.

ticularly for application to line casting machines, it will of course be understood that it .is also applicable to composing machines,

and machines for casting and composing type, type dies,etc.

Having described my invention what I claim is: I

1. In combination, two vertically arranged slides, a horizontally disposed finger key, and an automatic dog carried by the key and controlled by the operation of the key so as to actuate the slides alternately. I

2. In combination, two slides, a single finger key, an oscillating dog carried by the key, and stationary means for reversing the position of the dog at each action of thekey so as to actuate the slides alternately.

3. In combination, two slides, an actuating member, andan automatic dog carried and controlled by said member and provided with two shoulders which engage the slides alternately.

4c. The two slides, a reciprocating dog, an actuating member carrying said dog, and

stationary cooperating means whereby the v reciprocation of the dog reverses its posit-ion periodically, so that it will actuate the two slides one at a time.

5. In combination, the actuating member,

the dog mounted to vibrate and also shift bodily sidewise on the member, the two slides, and means to vibrate and shift the 7 dog, whereby the dog engages the slides one at a time. i

6. In combination, the two bars J and J, a reciprocable finger key, a dog provided with shoulders, and mounted to move relacooperate with the dog during its reciprocation, substantially as described.

7. In combination, the barsJ andvJ, finger key K,the slotted dog carried by the finger'key, and having a pivotal and shifting motion thereon, and a stationary member, M, to cooperate with the dog whereby the bars are actuated alternately.

In testimony whereof I hereunto set my hand this 20th day of November, 1911-, in the presence of two attesting witnesses. 7
