To all whom it may concern.-

Be it known that I, ROBB MAOKIE, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Apparatus for Selecting and Operating Mechanical Devices, of which the following is a specification.

Figure 1, of the accompanying drawings illustrates a side elevation of the receiving instrument. Fig. 2, illustrates an end elevation of the receiving instrument forward of the magnet and showing the cylinder and brushes. Fig. 3, is a view of spring bolt and its semi-cylindrical casing; Fig. 4, a view of cylinder spread out on a plane showing position of brushes and the direction of current when lamps are in circuit; Fig. 5, a view of cylinder spread out on a plane showing position of brushes and direction of current when the lamps are out of circuit; Fig. 6, a side view of part of the apparatus showing the spring bolt which has just passed the end of casing and is beginning to throw out looking bar. Fig. 7, is a diagram showing two sets of lamps .in main line circuit; arranged to be cut in or out of circuit by the receiving instrument located in an independent circuit operated by impulses thereon. In this figure the lamps to the left are in circuit and those to the right are cut out. Fig. 8, is also a diagram showing two sets of electriclamps in independent circuits, and receiving instruments operated by impulses from the main line, as in Fig.7. Fig. 9, isaview of thelower part of the apparatus showing a modified structure by which the cut-out or other device may be operated by a crank on the end of the shaft.

In a patent granted to Aden A. Hatch for electric signaling apparatus, dated May 14, 1889, No. 403,104, there isdescribed areceiving apparatus for working out a series of combination impulses in which there are shown two sets of electro magnets with their armature levers and means for shunting the current from one set' to the other to return the combination sector to its starting point.

So far as the operation of working out the combination of a receiving instrument is consequence or combination to select the semaphore he requires. The selecting instrument completes the phase represented by its arrangement of impulses; the effect of this is to subject the mechanical devices to the impulses from the transmitting instrument by which they are operated. So in a series of motors for driving machinery, one of these selecting instruments may be used to operate mechanicaldevices to turn off or restore the current to the motors. And the invention is illustrated inthe drawings to turn acylinder whereby an electric lamp may be lighted or extinguished, and a modification of a mechanical device is shown in Fig. 9, for operating such devices by means of a crank. Thus from the beginning to the end of the work, everything is under the control of the transmitter.

Upon a main line or independent circuit there may be erected a series of these receiving instruments, each of which may be connected with mechanical devices for operating an electric lamp. Such lamps may be nun'1- bered and as each receiving instrument responds to a predetermined arrangement of impulses the mechanical devices connected with the one selected will be first subjected to the operating or controlling impulses from the transmitter by working out the predetermined arrangement of the receiving instrument, and when thus prepared otherimpulses are transmitted which operate the mechania local circuit or release a mechanical de-\ vice operated by a weight or spring which when run down is again restored by hand, or again, to call a station operator who responds to the call and performs some work to enable the transmitter to proceed with some other electrical work.- These instruments are therefore not under the control of the transmitter, but require additional and other aid to perform their work.

The receiving instrument is constructed upon a suitable base A, provided with the uprights B, which constitute the frame work of the apparatus. uprights is the shaft a, and secured to this shaft so as to rotate therewith is the sector 0 supported by its arms 0, which has a normal forward movement (from right to left) im-r parted by a spring or weight as 0 or other suitable motor and a backward movement re- 7 turning it to starting point imparted by the armature lever of the magnet, which will be fully explained.

An elect-ro-magnet D, shown in Fig. 1, re-. ceives the impulses from the transmitting in strument and acts upon its armature lever d, attracting it to the pole of the magnet when V the circuit is closed,and is in turn retracted by springnl when opened; thus giving to this lever a movement responsive to the transmitted impulses. A series of these impulses is selected to suit the particular receiving in strument and the impulses thus sent work out the combination upon the sector of the instrument chosen, by means actuated orc'arried by the armature lever d, and moving with said lever; for example; the particular sector as shown at c in the drawings represent the following combination, a dot, an interval, two dots, an interval, a dot, an interval, two dots, an interval, a dot, an interval, two (lots, an interval, a dot; it will be seen that between each dot and dash of the above combination there is an intervening space; as the armature lever is drawn toward the the magnet pole it actuates a pin as 01 which touches upon the keys of the combination, impedes its normal progressive movement for ward, and holds it until thelever is again lifted, so that the sector takes a fresh start forward with each impulse; atthe same time the armature lever is arrested by the keys and is thus prevented from attaining its full stroke; when however, the finger descends through one of the spaces or when the combination is entirely worked out, the armature lever obtains its full stroke and throws the sector back to starting point, in thefollowing manner: Suitably mounted so as to vibrate with the shaft a is acollar a This collar is provided with a projection as a, which is slotted so that the rod a, may pass easily Suitably jonrnaled in these through the slot, whose other end is attached to the armature lever 01', and vibrates therewith; the upper end of this rod is provided with the shoulder a which may be an adj ustable nut as shown in the drawings or the collar and rod may be rigidly connected and the armature lever slotted. As the lever vibrates and its full stroke is impeded by the keys, this rod slides up and down through the slot in the projection 0, but when the armature lever is released and drops upon the magnet pole, the shoulder a catches the projection a and throws the sector back to starting point.

It has been said that the armature lever would be left free to return the sector to starting point when the combination had been worked out, and this statement is ordinarily true but in my apparatus I propose to make use of the mechanism of the receiving instrument to perform mechanical work after the combination is worked out and hence I have provided means for catching and holding the sector; so that it may notice returned to starting point until this work is accomplished. It may be said therefore that in my apparatus the combination is used to set the receiving instrument, to receive other impusles to perform this work and this is done by the following devices: b is a rod pivoted at b Its upper end is provided with a socket as shown at-b Upon the shaft 0, and secured toit or to the hub of the sector is a projection b which when the sector is at its starting point is in the position shown in Fig. 6; the end of the rod is held against the projection by the spring b as the sector moves forward the top of the rod b is pushed out by the projection b until it comesopposite to the socket b into which it drops when the sector has reached the end of its forward course, thus holding the sector in position and setting the instrument to receive the additional impulses for the mechanical work; this position is shown in Fig.1; the armature lcverd does not as yet obtain. its full stroke because its stroke is limited by the projection of, and collar or, and will not obtain its full stroke until the mechanical movements are given, but it has sufficient movement to do this work which is accomplished by the following means. Upon a shaft as E, suitably journaled in the frame, I have placed the cylinder 6', upon which the black spaces are insulations and the others, conductors, and on the 'same shaft E, a ratchet wheel e operated by a pawl 6 actuated or carried by the vibrations of the armature lever 61, as shown in the drawings, (Fig. 1). This pawl is pivotedto a rod a, suspended fromthe armature lever, and its lower end is normally pressed toward the ratchet by the spring e The pawl however, has an arm e, which projects above its fulcrum, and during the forward movement of the sector the upper end of this arm is in contact with a cross-bar 0 secured to the arms of the sector, and forms the are of a circle whose center is the shaft a. When the combination has been worked out, the end of the pawl arm 6 escapes the end of cross-bar c and allows the pawl to be thrown into engagement with the ratchet about the time the projection 6 has entered the socket b and has locked the sector and set the machine for mechanical work. Another set of impulses are now givenby the transmitting instrument which operates the armature lever of the magnet which imparts a rotating movement to the shaft E, and the cylinder 6; resting upon this cylinder are a set of

brush es

1, 2, 3, 4, and the operation of the device will be readily understood by looking at Figs. 4 and 5. Let us suppose the cylinder begins its movement with the brushes contacting with the cylinder as shown in Fig. 5; the current then is from the generator F, through

brushes

2 and 3, back to the generator. The cylinder is turned step by step until the opposite side is reached when the brushes are all upon the conducting spaces; the current is now from the generator F, brushes 2 and 1, lampsf', brushes 4 and 3, back to generator. The lamps are now lighted and when this occurs the armature d is released, obtains its full stroke and throws the sector back to starting point, and this is accomplished as follows: On the shaft E, is secured a hollow bar H, to revolve withv the shaft and isv provided with two spring bolts h, impelled outwardly from the center; and attached to the frame is a semi-cylindrical casing 71 arranged as shown in Figs. 1, 3, and 6, within wh ch the hollow bar H with its spring bolts are turned, and confined until one of them has passed the end of said casing h when it is impelled forward by its spring striking the end of the locking-bar b, and releasing the sector; the armature lever being free to attain its full stroke returns the sector to starting pointin the manner already'described. The bolt which has thus performed its work remains thrust out until it reaches the inclined plane h and is returned to its place by its own movementon this plane.

The operation of extinguishing the lamps is performed by a repetition of the same im pulses, viz: a series of combination impulses to set the receiving instrument and hold it in place, then a series of impulses to perform the mechanical work in turning the cylinder, and when these are finished the other or opposite spring bolt releases the sector and the armature lever throws it back.

The cogged segment is, pinion k and ratchet k illustrate parts of a retarding device, which may be used with a pendulum escapement, or a dash pot may be substituted or any other of the well known means for retarding may be used to steady and regulate the forward progressive movement of the sector and need not be further described.

I do not limit myself to the particular construction or operation of the parts of the instrument. For example, the transmitting instrument may be the ordinary telegraphkey or an automatic device constructed for the purpose; or any of the combination receiving instruments may be used as well as the Hatch; a mechanic may readily substitute other specific means for locking the instrument or for releasing it, and cranks, eccentrics, worms or other mechanical instrumentalities may be introduced for performing the mechanical work, but I believe I am the first to conceive and carry out in a practical apparatus (of which I have shown and described one form) a plan for operating a receiving or.

selecting instrument and by means of impulses from the transmitting instrument pick out and select any one of a series of mechanical devices, and by means of the impulses subject this device to other impulses from the transmitting instrument, which actuate the mechanical devices and perform mechanical work.
