To all whomfz't may concern: I I

Be it known that I, JoHN.HAYs-HA1\r- MOND, Jr, a'=citizen of the United'States, re-

siding at Gloucester, in the State of Massachusetts, have invented certain new and useful Improvements in Teledynamic Controls, of which the following is a specification This invention relates to systems for the control of mechanisms at a distance by means of radiant energy or in other ways, and relates more. particularly to systems in which radiant energy transmitted from a distant station actuates electrical apparatus at a receivingstation, which causes the operation of mechanisms worked by fluids under pressure or by other means,

By my invention I am enabled to control mechanisms at a receiving station in such a 1 way that they may be held in certain predetermined positions, this control-beingefiected by stopping the transmitted wavesafter sending them for certain definite periods of time; by sending waveimpulses of difierent frequency, this being done by varying the amplitude of the waves or'byvarying the wave-group frequency; by changing the intensity of the received currentsnor in any other suitable manner. One method suitable forcontrolling the receiving apparatus in my present invention, is that shown and described in my application for'U. S. Letters Patent Serial No. 750,705,,but I do not confine myself'tothis method, but may employ any other method suitable for my purpose. ln'the present application, I show only the apparatus vat a receivingstation, but it is to be understood that there is a transmitting station with suitable apparatusope'rating in partly in sectio n.

conjunction with my receiving station.

Y Figure 6 shows a cross section taken still nearerthe left end of Figure 2.

. Figure 7 shows a cross section of the valve EJ at the pipes 3 and 13.

' In the figures, A is a receiving antenna, grounded at E through the inductance coil L and the variable condenser C. This an tennacircuit is preferably tuned to the wave lengthof the transmitting station, as is also the oscillation circuit L C, comprising the inductance coil L and the variable condenser C, this oscillation circuit beinginductively coupled'with the said antenna circuit. By means of the rectifying detector Rand the stopping condenser D, unidirectional current impulses are supplied to the relay F, which,

when actuated, permits current to flow from the battery B through the coils of the electromagnet M. The plunger or movable core N of the electromagnet is connected by means of the rod K with the valve Ll. The movable part of the valve I slides in the fixed I part J and is attached tothe frame G. A' wheel W is connected with the movable frame G and runs in the fixed framework H. A tension spring S connects the fixed part J and the movable part I of the valve LT, and tends to pull the part-I toward the right to its initial position, as shown in Figshown, which is connected by means of a rod with the clutch gear X, X, X which operates the clutch Y which connects the engine'Z with themain shaft Z". The spring S tends to keep the clutchgearin the posi- A tank T contains compressed airflor some other fluid, A pipe 1' leads from tank T to the pipes 2, 4c and 6, which enter one side of the fixedpart of the valve J. The pipes 3 and 5 are exhaust pipes leading from the same side of J. The pipes 12, 13, 14, 15 and 16 enter the otherside of J, directly opposite the pipes 2, 3, 4, 5 and 6, respectively. The pipe 17 enters the same side of J as does pipe 16. The pipes 12 and 13 lead to the right end of cylinder 0, and pipes 14 and lead tothefleft end of cylinder 0.

Pipe 16 leads to: the right end and pipe 171'- to the left end of cylinder U. The movable part of the valve I contains the ports 'i, 8, 9, 10, ll'and 18, All of these ports, except 18, extend through from one side of I toithe other, but cover'onlya limited part of .the

circumference of I, so that these ports will connect the pipes containing working 'fi'uid' on one side of J with thepip'es on the-other side of J only when I is rotated on itsaxis through a certain angle as shown in Figure 5. At the places where the exhaust pipes 3,

Omit pipes3 and 5 altogether, and exhaust 1 directly through the enlarged ports in J The port 18' is onone side, only of I, and serves to keep pipes 16 and 17 in communi-v cation with the atmosphere when the valve I is in its initial position. I

' The framework H has two parallel members 19 and-20, which serve as tracks for' the wheel W torun -up on.' 'These members 19 and 20 are connected .by the pieces 26,

26, which serve to support 19. The fingers v21, 22, 23, 24 and 25 are pivoted, respectively,

at 27, 28, 29, 30 and '31. These fingers are normallyin the position shown 'in Figures 1 and 2. When the movable part I of the hind it.

, and along the lower track- 20,'and will lift finger 25 and return to its initial position.

When no electrical impulses are being received at the receiving. station, .the mechanism is inits initial-position, as shown in Figures 1 and. 1*,'the electromagnet M is notenergized, and;.the.valve I, frame G and wheel Ware held at the right by spring S.

f The pipes" 2, 4 and. 6, which are connected with the tank T, are closed, and the pipes 13, 15, 16 and.17 are open, sothatboth ends ofthe cylinders .O and U are in com-' munication with the atmosphere. The clutch Y is set and is held in this position by the spring \Vhen electrical electromagnet M will be energized, thekeep steering gear V amidships.

impulses are received the 1,41a,sse

plunger N will be drawn to the left, and, by means of the rod K, will draw valve I,

frame G and'wheel W to the left against the 'pull of spring S. If the electromagnet M is de-energized when the wheel'W has passedto the .leftof the tip of finger 21 and efore ityreaches finger 22, spring Swill draw the movable mechanism to the right,.

wheel'W will run up finger 21 and'will be held at the top of the latter. The valve I will thus be rotated on its axis, and the port 9 will open communication between pipes 2 and 12, so that fluid from tank will flow into the right end of cylinder 0.

.At thesame time pipe 13 will be closed, and

port 10 will open communication between pipes 15 and .5, so that the left end ofcylinder 0 can exhaust. Piston P will therefore move to the left and by meansof rod Q will operate steering gear V in one direction.

If the electromagnet M is de-energized when the wheel W has passed to the left of the tip of finger 22 and before it reaches finger 23', wheel W will be drawn to the top of finger 22, and valve I will be-brought into the position where port 9 will open communication between pipes at and 14, so that fiuid from tank T will flow into the left end of cylinder 0. At the same time pipe 15 will be closed, and port 8 will open communication between pipes'13 and 3, so that the right end of cylinderO can exhaust. Piston P will therefore move to the right, and will cause steering gear V to be'operated in the opposite direction from before.

. If the eleetromagnet' M is de-energized when the wheel'W has passed to the left of the tip of finger 23 and before it reaches the tip of finger 24, it will be drawn to the top of finger 23, as shown in Figure 5 and at IV in Figure 2. Valve I will thus be brought into a position where port 10 will open communication between'pipes 6 and ,16, so that fluid from tank T will flow into the right end of cylinder U. At the same left 'end of. cylinder U can exhaust.

to the left, overcoming the tension of spring S and releasing clutch Y, so that engine Z will be disconnected from main shaft Z.

In this position of -valve I, pipes 2, 4, 12 and 14 will be closed} and pipes 3, 5, 13 and 15 will be open, so thatboth ends of cylinder 0 will be in communication with the atmosphere, and springs S and S will tend to Under some conditions, pipe 17 need not run to valve IJ, but may simply be a short outlet or exhaust from the left end .of cylinder U or it may be omitted altogether, and the left end of cylinder U be open to the atmosphere.

If the electromagnet M isde-energized afmisses ter wheel W has. passed to the left of. the tip of finger 24, spring S willjdraw the movable mechanism to the right, and wheel'W will travel along the lower track 20, as shown in Figure 6 and at W in Figure 2, until it reaches its initial position as shown at W in Figures 1, 2 and 3. The various positions of the valve can be passed over without operating the steering gear and the clutch, for

these mechanisms will not be operated unless the valve is stopped in certain positions, and

the wheel W runs up tothe top of fingers 21, 22 or 23, thus rotating the valves and opening the appropriate ports. Although I have here shown means for releasing the clutch Y, I can also control the setting of it by imeans of my valve without departing from the spirit of my invention.

It will thus be seen that the operator at the sending station, by stopping the emission oi Waves after predetermined time intervals,

can operate a steering gear at the receiving station and thusturn the rudder to starboard or to port, or he can release a clutch and disconnect the engine 'from the propeller, and

' can restore-theavhole operatingmechanism to its original position.

Instead of fixing the position of the wheel W and the valve I simply by stopping the transmission of waves, I can employ .the

means .shown in my application for U. S. Patent, Serial. NO. 750,705, where impulses are sentat a certain rate so as to energize the electromagnet M to a certain degree and so attract the plunger N only as far as may be desired. When the wheel W has reached the desired position, the transmission of impulsesis stopped, and the valve I assumes the position where the desiredmechanism .is operated. Any-of the means described in the 'above mentioned application may be employed ;with my present invention, and any other suitable means for stopping the travel cation, Serial No. 7 50,705."

' a of the :plunger Nat any desired point may be When desirable, any suitable form of dashpot or similar apparatus may be used to de- I lay or slow up the action of electromagnet M and plunger N, such, f or instance, as that shown and described in my aforesaid appli- I have shown my radio receiving station tuned to wave length only, but I can also tune it and the corresponding transmitting station to amplitude variation frequency or Wave group frequency, as fully shown-and described in various applications of mine for U. S. Letters Patent. i I y In the art,-it is well. known that in, order to attain eflicient tuning it ,is necessary to have circuits whose electrical oscillation is persistent and slowly dampened. Therefore, in all cases where Ichave shown detectors' it may be understood that I may em-' ploy such detecting devices as present the least ohmic resistance in a circuit. Moreover, by means well known in the art, the interconnection of the oscillating circuits may be made to producean amplification effect of the energy transmitted through them, rather than to sufier a direct loss due to the resistance of the circuits.

In these specifications the terms .r'ight and left and up and down, used in describing the operation of my invention, refer to the particular arrangement of apparatus shown in the drawings, and might, of course, be changed with some other arrangement of the apparatus without departing from. the

spirit of my invention.

I have here shown my invention as applied to the operation of certain mechanisms on a torpedo or other vessel, but I may also apply it to the operation of other mechanisms on a vessel or in any other suitable place; and in general, I do not confine my:

self to the particular apparatus and mecha nisms here shown, but changes and modifications, within the knowledge of those skilled having been actuated to a certain extent and then released by said electromagnet, and a plurality of fluid operated mechanisms sepa- -rately controlled by said valve-member.
