emma-umm riginal applications filed January 2B, 1913. Serial No. 744,793, and'ilay 3i, i913, Dvded'and this application filed October 19?..5.

To @ZZ cli/icm irl may concern it known that if, Rnorrnxno L Frissen- DEN, of Brookline, in the county oi Norfolk tric lilachinery, of which the foilowingis e' specification.

The invention herein described relates to electro dynamic apparatus and methods and to the generation, the ntirizotion. the trans'- niission and the receipt of electric energy and more particularly to the production and detection or compressionol Waves, and still more particularly to' submarino signaling.

It has for its object increased eliciency in these lines.

This application 1s :i division of the ap- A plication iled hy me whim matured into Let-ters Patent Nef ,167,366, issned Jannw ary 4, 1916, which vos :i division of my application Serial No. 744.793, file/.i January e9, i913.

The invention wiil be understood more particularly by reference. to the drawings.

in which it is shown in its preferred embodiment.

in the drawings Figure l is ai diagrammatic cross section or :i reciprocating dynamo capable of being' nseci inJv carrying out my invention. Fig. 2 illustrates the application oi' o gos engine to such dynamo.

A suitobie form of apparatus for carrying out this invention is shown in Fig. Here 40 is a copper tube soy approximately eight inches in diameter and eight inches long (the length being' preferably equal to or less than' the diameter). is the magnetizing coii of the magnetic circuit, 113-413 being the north pole and lli-14 being thl south pole. The'magnetic flux Hows from 43-i3 through the top air gap to the armature or core 4l, thence through the bottom air we and hack t irough the outside ring',n to t3- Thetnoe 40 lies in the two air gaps and such part of it as is not over the. windings 46, is preferably slotted as at or otherwise marie of high resistance. The windings #5.6. i? are preferably Wound on the core il though they may be Wound the insirle of the poles 43 i3, M -44. 'The core ii anci the poles ere preferably slo #.rceliy and reclieliy Specification of Lettere Patent.

My inventionforins e very eliicient gencrater of alternating' currents The tube 40 may be fixed directly to the piston rod of o ges engine es in Fig. 3 Where 70 indicotes the cylinders ofthe ges engines, the pistons 7l being Set to operate in opposite directions to each other. of srh units are used they may be connected in parallel, and the synchronizing effect is so strong that no crank shefis fly wheels aref necessary and t ie lcon he done by timing; the ignition elo This is of great importance with engines of the type inventer? icy me where the power per cylinder is so greet the shaft if it transmitted the power 'ironici have approximately the seme diiameter evs the cylinrler.

What ciaim ns my invention is;-

l. Apparatus for generating electrical power, comprising' fr plurality or" reciprocating engines and :i plurality of reciprocating clynamos operatively connected to seid heat engines, said reciprocating Clynoroos being leiectricnliy connected; with each other enel having substantially no sei induction, coing thereby maintained in synchronisin.

2. Apparatus for generating alternetinglg' electrical power comprising :i plurality of reciprocating engines and n tplurality of reciprocating dynamos operetiveiy connected to scid engines seid reciprocating i moe being eiectricaily connected with each other and having substantially no seit-iiirnction, being thereby maintained in svnchronism, and the frequency of the cin-rente rei. lered independent of :my natural perico?, of the engine.

3. Apparatus for generating eiectriciel power comprising e plurality reciprocating ensrines and a pnreiity of reciprocating alternating cig/*names operatively oennecteii `Where o number l to Said engines, said reciprocating dynainos being electrically connected with each other and having substantially no selfdnduction, being thereby maintained in synchronisni, and the frequency of the currents generated rendered independent of any natural period of the engines.

4. Apparatus for generating electrical polwer -comprising a plurality of engines and a plurality of reciprocating alternating dynamos operatively connected to said engines, said reciprocating dynarnos being electrically connected with each other and having substantially no self-induction, being thereby maintained in synchronisni.

5. Apparatus for generating alternating` electrical power comprising a plurality of engines and a plurality of reciprocating dynamos operatively connected to said engines, said reciprocating dynalnos being electrically connected with each other and having substantially no self-induction, being thereby maintained in synchronisin.

6. Apparatus for generating alternating electrical power comprising a plurality of explosion engines and a plurality of reciproeating dynames operatively connected to said engines, said reciprocating dynainos being electrically connected in parallel with each other and having substantially no selfinduction, being thereby maintained in synchronism.

7. Apparatus for generating electrical power comprising a plurality of explosion engines and a plurality oi' reciprocating alternating dynalnos operatively connected to said engines, said reciprocating dynan'ios being electrically connected in parallel with each other and haring substantially no selfinduction, being thereby maintained in syncln'onism. i

8. Apparatus for generating electrical power comprising a plurality of engines and a plurality of reciprocating dynainos opera tively connected to said engines, said reciprocating dynamos being electrically connected in parallel with each other and having substantially no self-induction, being thereby maintained in synchronism and adjustable in speed independently of the natural frequencies of the engines.
