ELECTRICAL RINGING 0 BELL-S FOR SUBMARlNE SlGNALlN G.

SPECIFICATION forming part of Letters Patent No. 744,336, dated November 17, 1903. Application filed December 24, 1900. Serial No. 40,888. (No model.)

To all whom it may concern:

Be it known that I, ELISHA GRAY, a citizen of the United States, and a resident of High.- 1

land Park, in the county of Lake and State of Illinois, have invented a new and useful cation, in explaining its nature.

The invention relates to an improvement in the electrical ringing of bells for subma-' rine signaling.

Heretofore all attempts to ring submerged bells by the direct blow of a hammer electrically actuated have been undertaken by in closing the whole apparatus, :including the bell and the hammer actuating mechanism, in an air-tight i-nclosure, so that the sound or vibrations of the bell were first communicated to the.airenvelop, thence to the inclosing medium, and then to the water surrounding it. This method of producing sound vibrationsso deadened them that very little impulse, if any, gets into the water, and the device is practically of little or no use for submarine signaling.

By my improvement the bell and bell-hammer are divested of covering of this character and are submerged in the water and in direct contact upon all sideswith it, while the electrical operating mechanism for actuating the hammer is entirely contained within an air-tight chamber, which may also be submerged with the bell.

I will now describe my invention in detail in connection with the drawings, wherein- Figure 1 is a general view of the bell and its actuating mechanism. Fig. 2 is a plan or top view of the rocker which carries the laminated armatures that are actuated by the electromagnets. Fig. 3 is a detached view of that part of the air-tight box where the inner and outer mechani'smof the striking-hammer unite, also Showing the manner of sealing the outer moving from the inner moving parts and the means. for clamping the air tight chamber with the hammer-uniting mechan- ,ism attached thereto to the .bell. Fig. 4 is a View showing a modification to which reference is hereinafter made. p

A is a bell which in Fig. 1 iS represented in cross-section.

B is a circular drum with sealed top and bottom ends, forming a water and air tight chamben;

O is the bell-hammer, which is actuated by I the magnets D E and D E, which are mount- .ed in the chamber of the drum.

7 F is'a cast-iron rocker. (Shown in plan in iFig. 2;) It has trunnions f, mounted in the bearings G G. Glamped within the frame of the rocker are four laminated armatures H I gand H I. These laminations are laid to- ;gether so that their edges form-the faces of gthe armatures that are presented to the poles of the magnets. There are four magnets, the poles of.which present themselves to the armatures and which face downward over the upward faces of the armatures in the position Shown in Fig. 1.

Fastened to the center of the rocker F and extending downward at right angles to it is an arm or lever K, having a forked lower end L, which engages with a roller M (See Fig. 3) on the end of a short arm N, which is fastened to a shaft 0, having a bearing in the air-tight box P, located within the bell. The chamber of this inner box P communicates with the chamber of the .drum B through the hole in a tube Q. The tube is threaded at both ends. The lower end is screwed firmly into the lower box, while the upper end passes upward through the crown of the bell and through the plate R, which forms the lower end of the drum B. The bell is seated 'inside to receive the upper end of the box P. A heavy nut S is screwed onto the upper end of the tube Q down upon the plate R to clamp the" upper drum and lower box together and.

* straddles the roller'M on the end of the short lever-N on the rock-shaft O. Secured to the outer ends of .therockshaft are two down-.

, The lower ends'of these arms meet at a point directly under the center of the lower box P ward-extending inwardly-bent arms T T.

and are there secured to the bell-hammer arm U, which carries at its lower end the hammer O.

Instead of packing the rock-shaft O to prevent water passing into the chamber of the box P, which would cause too much friction,

the following manner of packing may be used: V V are rubber tubes. 1

W W are sleeves screwed into the sides of the box P. In these sleeves or journals the rock-shaft 0' turns loosely. It also passes through the lever N, which is rigidly secured to it. Sleeves X X are now forced upon the ends of the rock-shaft and the air-tight rubber tubes V V are slipped onto each end of the shaft and wired tightly at each end to the sleeves IV W and X X. W'hen the bellhammer 0 moves, there will be a torsional strain putupon the-rubber tubes, according to the direction in which the hammer moves.

The hammer and the arm U that carries it are so shaped as to cutthrough the water I with least resistance.

The rocker F may be used in teamsthat is,

' one or more carrying armatures may be connected with it to be simultaneously operated by magnets in the manner herein indicated and in Fig. II have represented the use of a second rocker F with armatures and operatingmagnets supported upon trunnions within the chamber of the drum and connected with the rocker F by four connecting rods, one of which (lettered 1)is. shown as well as a portion of the other, (lettered 2.) The other twoare behind the magnets. The group of magnets E'E are connected electrically and when charged act 'conjoin'tly upon the armatures of both rockers, and the bell-hamm er is thrown with great force against the bell in the direction of the arrow. The group of magnets D Dactsimilarly. If now the group E E is deenergized and the group D D energized, the hammer will ,bethrown as forcibly against; the bell,

or source. of electrical; power may be thrownfrom one group of magnets to the other, causing strokes of the bell in any predetermined order.

I do not confine myself in the employment of this apparatus to the use of a conventional v form of hell, but may apply it to striking any= sonorous substance whatever.

It will be understood that the apparatus, is
