Specification of Letters Patent.
Patented Aug. 8, 1916.
Application filed October 16, 1913. Serial No. 795,397.
To all whom it may concern:
Be it known that I,. DAVID PE'rnI-PAL- MEDO, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Typographic Composing-Machines, of which the following is a full, clear, and exact description.
This invention relates to means whereby the successive actuations of a single key in machine will cause the release of matrices serially from two or more magazine channels. Numerous mechanisms for this purpose have been devised; but I believe that, with all of them, the successive actuations of the associated key causes the two escapements to be alternately operated, each through its full cycle.
The term escapements as herein used, has reference solely to the mechanisms carried by the magazines for holding the matrices in the magazine channels and for releasing them one by one; and is not intended to include either the keys or the mechanism intermediate of the keys by which the escapements are operated.
My mechanism is radically different in principle from all the others, because I make use of the fact that nearly all successful escapement mechanisms have a cycle of movement which includes two steps; that is to say, they are such that the down stroke of the associated key causes the escapement mechanism to move through half of its cycle, thereby releasing the lowermost matrix in the channel and interposing a stop in the path of the next succeeding matrix by which the matrix column is stopped in an intermediate position; while the up stroke of the key causes or permits the escapement mechanism to move through the last half of its cycle,that is back to its normal position, whereby the stop referred to is either allowed to move down, or withdrawn and the first named stop moved into position, so as'to permit the matrix column to move down to its normal position.
My mechanism is such that when the key, common to two or more channels, is depressed, it moves the escapement mechanism through the first half of its cycle and interposes in t e path of some piece of the train of mechanism a stop such as will hold the escapement mechanism in this intermecapement is made diate position while the key moves on its return stroke and until the next or some succeeding downward movement of the kev. When two escapements are to be operated alternately by a single key, a down stroke of said key will cause one escapement to be moved through the first half of its cycle with the result of releasing the matrix from the associated channel, while the other escapement which was in the intermediate position will be permitted or caused to move through the second half of its cycle. If more than two escapements are to be operated by a single key, two of them will move in the manner stated whenever a key is depressed, but the other escapements will be in and will remain in the intermediate position referred to, until some succeeding actuation of the key.
The invention consists in the combination with a plurality of two-step escapement mechanisms, and a single key, of intermediate mechanism such that each complete up and down movement of a key will cause one escapement to move through only onehalf of its cycle of movement, and will cause another escapement to move through the other half of its cycle.
The invention also consists in the more specific combinations of parts, as hereinafter described and shown in the drawing and pointed out in the appended claims.
In the drawing Figure l is a vertical sectional view of the lower end of a magazine channel and the escapement mechanism associated therewith when the latter is in its normal, position, together with a side elevation of the mechanism by which said escapement mechanism is actuated. Fig. 2 is a similar view showing the said parts in their intermediate positions. Fig. 8 is a plan view showing two adjacent magazines and the mechanism provided to enable a single key to successively operate the escapement mechanism of said two magazines in the manner hereinafter described. Fig. 4 is a rear elevation of the operating mechanism for said two escapements. Fig. 5 is a plan view of the escapement operating shafts and the adjacent parts of the two escapement operators.
In the exemplification of the invention which is shown in the drawing a peculiar two-step escapement is employed, which esthe subject matter of another application. It is to be understood, however, that any two-step escapement mechanism might be employed in lieu of that shown, provided that each escapement mechanism was provided with an operating element capable of being engaged by mechanism substantially like that shown for engaging the actuating element of the particular escapement shown.
In the escapement mechanism as shown there is a star wheel A having a plurality of arms a, a a a a. This wheel is mounted behind the magazine channel S with which it is associated, and in a position such that one of the star wheel arms only may be projected into the magazine channel so as to engage matrices therein. Normally one of the upper cars at of the matrix M rests upon that arm of the star wheel which projects into the magazine channel.
Another arm a of the star wheel is engaged by one end of a pivoted lever B, whereby that rotation of the star wheel which would otherwise be produced by pressure from the matrix column and which would result in the release of a matrix, will be prevented. This lever B has three arms. The lower arm is forked and it receives one arm (Z of the escapement actuating lever D. A third arm 6 of lever B enters a notch in a lever E; and therefore all three levers must move at the same time. The lever E is under the influence of a spring tending to mox e it and the other lever back to their normal positions, such as is shown in Fig. 2. hen, by upward pressure against arm (Z of the escapement actuating le er D, the lever B is moved out of the path of the star wheel arm (B, the end of the lever E is moved into the path of said arm; whereupon the weight of the matrix column will turn the star wheel until arm (4 comes into contact with the end of the lever E. In so turn ing the arm a of the star wheel is withdrawn from the channel and thereby the lowest matrix which it was supporting is released. Likewise the next arm a of the star-wheel is moved into the magazine channel beneath one of the upper ears of the next succeeding matrix. The matrix column will move down until the said ear engages the said arm, and thereby the matrix column is stopped. The escapement mechanism and the matrix column are now in the intermediate position shown in Fig. 2. 1
Associated with each escapement mechanism is an operator F which is in the form of a pivoted lever whose front end is upturned so as to be in contact with the operating arm of the escapement actuator D. A single key 9 is fixed to a sleeve G which is mounted on the same rod Q which serves as the pivotal support for a row of key levers. Rigid with said sleeve and extendassociated reeds H a pawl P in-g rearward therefrom are as many lever arms 9 as there are escapements to be operated serially. Resting on each lever arm 9 is a vertically movable reed H; and each of these reeds, at its upper end engages beneath an operator F.
Associated with each key, and as many escapement mechanisms as it is desired to have a single key operate serially, is a rotatable shaft K, to which are attached as many disks N as there are escapements to be actuated serially. Each of these disks has formed in its periphery a plurality of depressions a between which are elevations n There is also attached to this shaft a ratchet wheel 0. There is also pivoted to one of the adapted to engage said ratchet. By the depression of the key 9 and the consequent elevation of all of the associated reeds H, the pawl, by its engagement with the ratchet, will turn the shaft through an arcual the distance between'the two ratchet teeth.
Each of the operators F has projecting laterally from one side a pin 7 which overhangs and engages the periphery of the associated disk N. When one disk N is in a position such that the associated pin 7 of one operator is over a depression a therein, said operator is allowed to descend as the key makes the return movement; and the escapement mechanism associated with this particular operator is allowed to move through the second half ofits cycle. The various disks are set with their recesses in staggered relation with respect to one another, so that when the pin of one operator F is resting in a reces n of its disk, the pins of the other associated operators are resting on the elevations n of their disks and are held up, thereby holding the associated escapements in the intermediate position. then therefore the key 9 is de pressed, all of the associated reeds H are moved up; but since only one of the escapement operators F is down, this one only will be moved by the upward movement of all the reeds. This one operator will be moved up with the result of moving the associated escapement through the first half of its cycle. As the reeds move up the one carrying the pawl will turn the disk carrying shaft K so as to bring the elevated surface n on one disk N beneath the pin f of the operator which was so raised. When therefore the key moves on its return stroke, and the reeds move down, the particular operator which had just been elevated is held up; and the associated escapement is left in its intermediate position. But the same arcual movement of shaft K, as just described, which moved one disk into the position to uphold the said escapement operator, also moved another disk so as to bring one distance equal to of the notches 91. therein beneath the pin 7 of another operator F. When the key g moves on its return movement the last named operator F will move down and the associated escapement will move through the last half of its cycle, that is from the intermediate to the normal position.
The described mechanism is simple in construction, and permits of indefinite expansion,-that is to say, any number of escapements may be made to operate successively to release matrices from the associated magazine channels by a single key lever. Moreover the mechanism is such that it may be added to the ordinary escapement operating mechanism, without any change in the latter.
Having described my invention, I claim:
1. In a typographic composing machine, the combination ofa matrix magazine having matrix holding channels, a plurality of two-step escapement mechanisms, a single key, and means operated thereby for serially moving said escapements through the first half cycle of movement, and whenever an escapement is so moved, for causing another escapement to move through the last half cycle of its movement.
2. In a typographic composing machine, the combination of a matrix magazine containing magazine channels, two step escapements mounted on said magazine, an escapement operator for each escapement, an associated key, and means whereby the two escapement operators are caused to move reciprocally,-the one from and the other back to its normal position by successive complete actuations of said key.
3. In a typographic composing machine, the combination of a matrix magazine having a plurality of matrix channels, a twostep escapement mechanism for each channel, which escapement mechanisms are mounted upon said magazine, two escapement operating levers mounted on the framework of the machine and engaging, respectively, with two of said escapement mechanisms, two connected rotatable disks whose peripheries are formed with alternately placed depressions and cam-shaped elevations,the depressions in one disk being alined with the elevations in the other disk, a single key and means operated thereby for imparting step by step rotary movements to said disks.

5. In a typographic composing machine, the combination of two two-step escapements, a single key, intermediate mechanism by which one down stroke of said key will cause one escapement to move through the first half of its cycle and the other escapement mechanism to move through the second half of its cycle, while the next down stroke of said key will produce the reverse movement of both escapements, and means for holding said escapements in the intermediate position in the interval. between two successive down strokes of said key.
6. In a typographic composing machine, the combination of a plurality of two-step escapement mechanisms, a single key, and mechanism intermediate of said key and the escapements whereby successive actuatifins of the key will operate the several escapements serially, causing each to move through one-half only of its full cycle.
