GEORGE A. LOWRY, OF EAST BOSTON, MASSACHUSETTS.

SUBIVIAR-INE-SIGNAL DEVICE.

Application filed May 23, 1907.

To all whom it may concern Be it known that I, GEORGE A. LOWRY, a citizen of the United States, residing at East Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Submarine-Signal Devices, of which the following is a specification.

This invention relates to means in submarine signal devices for producing an audible signal below the surface of the water, and more particularly to the type comprising a bell having a clapper for sounding the same, and the primary object of the same is to provide improved means for automatically and systematically producing an audible signal below the surface of the water, the operation of which does not depend directly upon the action of the water to sound the signal.

A further object is to construct a signal buoy provided with improved means for producing an audible signal below the surface of the water, and improved means whereby the particular buoy may be identified by its signal.

A. further object is to construct an improved buoy provided with a sub-marine audible signal apparatus, and improved means for automatically gathering and storing suflicient energy by the action of the water to operate the signal and to release and utilize the power to operate the signal.

A further object is to construct a buoy provided with a submerged gong including a hammer with improved means for locking the hammer and improved means for releasing and operating the hammer.

A further object is to provide an improved device of this character which will be simple, cheap and durable in construction and efficient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty of construction, combination and arrangement of the several parts hereinafter more fully described and claimed, and shown in the accompanying drawings illustrating an exemplification of the invention, and in which Figure 1 is an elevation of an improvement of this character constructed in accordance with the principles of this invention. Fig. 2 is an enlarged detail sectional view on line 22 of Fig. 3. Fig. 3 is an ele- Specification of Letters Patent.

yation of the operating mechanism, partly in section. Fig. 1- is a detail sectional view on line l1 of Fig. 3. Fig. 5 is a view similar to Fig. 1, showing the operating member in an adjusted position. Fig.-

6 is an end elevation partly in section of the operating mechanism.

Referring more particularly to the drawlugs and in this exemplification of the invention, the numeral 10 designates a' suit-- able buoyant body, such as a buoy or the like, which is adapted to float upon the Water.

The numeral 11 designates a suitable tu bular member of any desired size and secured to said member 11 is an arm 12 which is preferably spaced from the side thereof. The tubular member 11 is pivotally supported by the buoy 10 in any desired or suitable manner, preferably by means of a bar or rod 13, one end of which is preferably swiveled to the arm 12, as at 14c, and the other end is pivotally connected to the buoy 10, as at 15. Disposed between the tubular member 11 and the arm 12, preferably at a point adjacent the lower extremity of the member 11, is a grooved pulley wheel 16 which is mounted for rotation upon a suitable axle 17 secured between the extremity of the arm 12 and the member 11. The pulley 16 is preferably provided with a laterally projecting portion 18 which is preferably provided with an undulating or scalloped periphery 19 for a purpose to be set forth. The tubular member 11 preferably projects for some distance below the pulley wheel 16, and secured to the 6X tremity thereof is a bell 20. Secured also to the tubular member, preferably adjacent the pulley wheel 16, is a suitable bracket 21, and

pivotally supported by the bracket is a retainin dog or pawl 22, one extremity of whic is adapted to project through a suitable aperture or opening 23 in the tubular member 11 so as to engage suitable rack teeth 24: on a member 25, which latter is adapted to operate the signal in a manner to be set forth. This member 25 may be of any desired length and is of a sufficient wei ht to trip the bell hammer when it descen s. a

Pivotally mounted on the bracket 21 is a suitable arm 26, to one end of which is pivoted a suitable dog 2", and said dog 27 is preferably located adjacent the retaining dog or pawl 22 and is also adapted to project through the aperture or opening 23 in the tubular member 11 so as to engage the rack teeth 24 on the member 25. The free end of the arm 26 is preferably disposed at an angle to the body portion thereof, as at 28, and journaled on said end 28 is a suitable antifriction roller 29, which is so disposed as to engage the undulated or scalloped periphery of the laterally projecting portion 18 on the pulley 16 so that when the pulley is rotated in either direction, a vibratory motion will be imparted to the arm 26 through the medium of the anti-friction roller 29 lying against the undulated or scalloped periphery 19 of the portion 18.

A bell clapper or hammer 30 is preferably pivotally supported as at 31 to the bracket 21, and an arm 32 is connected tothe bell clapper or hammer 30 adjacent the pivoted point 31 thereof and is disposed at a substantial right angle thereto. Said arm is of such a length that the extremity thereof will project through a suitable slot or aperture 33 in the tubular member 11.

The member 25 is provided with lugs or projections 34, which are spaced from each other and preferably arranged behind the rack teeth 24. These lugs or projections 34 may be formed in any desired or suitable manner, preferably by cutting away a portion of the rear face of the member 25. The arm 32 is of such a length as to project into the opening between the lugs 34 so that when the member 25 descends after having been raised'to its highest position, the lugs 34 will successively strike the extremity of the arm 32 to rock said arm to operate the bell clapper or hammer 30. The arm 32 is preferably provided with a pivoted latch 35, which is adapted to yield to permit the lugs or projections 34 to pass-when the member 25 is raised, but when the member descends, the latch 35 will assume a position to be engaged by the lugs so as to rock the arms 32.

A suitable flexible member 36, such as a chain, or the like, is adapted to pass over the pulley 16, and one end thereof is secured in any desired manner to a suitable anchor 37 to maintain the buoy in its proper place. Secured to the free end of the flexible member 36 is a suitable weight 38.

The member 25 is adapted to be moved in the tubular member 11 and to assume a position within the lower extremity thereof. Assuming member 25 to be located within the lower extremity of the tubular member 11, it will be seen that when the buoy 1O rises on a wave, the pulley 16 will be caused to rotate in one direction due to the action of the flexible member 36 thereof, one end of which latter is firmly anchored, and to the yielding action of the weight 38. When the buoy rides down or descends into the trough of the sea, the tension will be released from the weight 38, which latter is suflicient to draw the chain around the pulley 16 and cause the latter to revolve in an opposite direction so that an oscillatory motion would be imparted to the pulley as the buoy rises and descends.

The rotation of the pulley 16, under the influence of the flexible member 36, will impart a similar motion to the laterally projecting portion 18, causing its undulated or scalloped periphery 19 to engage the antifriction roller 29 on the arm 26, which will vibrate the arm and cause the dog or pawl 27 to be raised and lowered. When the pawl 27 descends it will engage one of the rack teeth 24, and when it rises will elevate the member 25, which latter will be held in its elevated position by means of the retaining dog or pawl 22. This operation is continued until the member 25 has reached the limit of its upward movement, that is, until the retaining dog or pawl 22 is in engage ment with the lowermost rack tooth 24.

The teeth 24 which stand adjacent the dog or pawl 27 when the member 25 is at the limit of its upward movement, is preferably provided with an inclined or beveled face 39, so that when the parts are in this position and a further rotation is imparted to the pulley 16, the dog or pawl 27 will engage the inclined or beveled face 39 of the adjacent rack tooth 24 and will axially rotate the member 25 within the tubular member 31 from the position shown in Fig. 4 of the drawing to the position shown in Fig. 5. This rotation of the member 25 will cause the rack teeth 24 to pass out of engagement with the dogs or pawls 2722, thereby releasing the member 25, which latter, being then unsupported, will start to descend by the force of the gravity thereof. This position of the teeth 24 of the member 25 with respect to the operating pawl will also prevent the storing of further energy while the stored energy is being expended.

During the descent of the member 25, the lugs or projections 34 will strike the extremity 35 of the arm 32 and throw the bell hammer or clapper 30 outward and to the position shown in dotted lines in Fig. 3, and f after the adjacent lug or projection 34 has passed the extremity of the arm 32, the gravity of the clapper or hammer 30 will cause the same to fall against and strike the bell 20, thereby sounding the signal. This .1

operation will be repeated according to the number of lugs or projections 34 which are provided on the member 25.

Any suitable means may be provided for restoring or axially rotating the member 25 to its normal position, or to a position that the teeth 24 will be so disposed as to be engaged by the dogs or pawls 27-22 to again raise the member. A suitable and efficient means for accomplishing this purpose comprises a suitable lug or projection 40, which is preferably arranged adjacent the lower extremity of the tubular member 11, and said lug or projection is adapted to be engaged by a suitable cam face or surface 41 on the extremity of the member 25, which will rotate the member into its operative position as the member reaches the limit of its descent. The member 25 being thus properly positioned, the action or rotation of the pulley 16 will again lift the member 25 in the manner already described.

Any suitable means may be provided for regulating the speed of the fall of the member 25 to control or cause intervals between the sounds of the bell so that the sounds may be distinctly rendered. A suitable and efficient manner for controlling the descent of the member 25 consists in closing the lower end of the tubular member 11 as at 42 so that the lower portion of the tubular member 11 will hold water and said portion will always be full of water due to the loose fit of the member 25 therein and the openings 23-33 in the tubular member. It will thus be seen that when the member 25 descends, the portion of the tubular member 11 which is filled with water will act as a dash pot, as the water cannot be displaced except by passing up the sides of the member 25 and out through the openings 23-33, the member 25 being of a size to substantially fill the tubular member 11, thereby causing the water to offer a resistance against the descent of the member 25. A suitable and eflicient means for regulating the speed of the descent of the member 25, preferably comprises a valve or gate 43 adapted to close a suitable aperture or open ing 44 in the lower extremity of the tubular member, and this gate or valve 43 may be adjusted to regulate the opening 44 to permit the water to be displaced more rapidly, if desired.

Suitable and efficient means may be provided for holding or locking the bell hammer or clapper 30 directly after the latter has made a stroke, in order to prevent a constant light tapping of the hammer on the bell due to the vibration which will be imparted to the hammer by the action of the water. A suitable and efficient means for accomplishing this purpose comprises a bracket or support 45 which may be secured to the tubular member 11. Pivotally supported to this bracket 45 is a locking member 46 which latter is preferably provided with a bifurcated or cut-away portion 47, which is adapted to receive or stand astride of thebell hammer or clapper rod 30 and said locking member is adapted to rest upon a suitable collar or support 48, which latter is secured to the bell hammer or clapper rod 30 This collar or support 48 is preferably provided with an upwardly projecting pin or lug 49 adapted to enter a suitable slot or aperture 50 in the locking member 46 so that when the locking member is in a position to rest upon the collar or support 48, the pin or lug 49 will project into the slot or aperture 50 to hold the bell hammer or clapper against vibration. The locking member 46 is also provided with a bifurcated portion 51 which preferably projects on the oppo site side of its point of pivotal support, and disposed within said bifurcated portion 51 is a suitable bar or rod 52 which is preferably provided with tappets 5354 disposed on each side of the bifurcated portion 51, so that when the rod or bar 52 is lowered, the tappet 53 will engage the bifurcated portion 51 to move the locking member 46 about its point of pivotal support in one direction and when raised the tappet 54 will engage said portion to move the locking member 46 in the opposite direction. This bar or rod 52 is pivotally connected at its free end to the arm 32 so that the locking member 46 will be controlled by the action of the arm 32. It will thus be seen that during the descent of the member 25 the lugs 34 will serve first to unlock the bell hammer or clapper, and then move the latter about its point of pivotal support. The locking member 46 is of any suitable light material and of a size to present an extended area to the resistance of the water, but is of sufficient weight as to tend to resume its normal position, but inasmuch as it presents a large area to the water, it will fall there through at a much lower rate of speed than the bell hammer. lVith this construction the bell hammer will impart a blow to the bell and recover while the locking member 46 is descending to a position to permit the lug or pin 49 to enter the slot or aperture 50 to lock the bell hammer or clapper 30 away from engagement with the bell.

The weight 38' is preferably heavy, enough to hold the buoy 10 in approximately the position shown in Fig. 1 of the drawing dur ing' ordinary weather, but when a strong current is running, the weight 38 may be drawn upwardly toward the pulley 16, and

.in order to prevent this weight from coming to a stop in too forcible a manner by striking a portion of the apparatus, and thereby straining the other portions thereof, a suit able and efficient means is provided for cushioning the weight so as-to relieve the jar. This cushioning device preferably consists of a cylindrical member 56 which is supported by the bracket 21 and is provided with a closed top 57, having an aperture 58 through which the flexible member 36 passes. The lower extremity of this cylindrical member 56 is preferably open and provided with a flared mouth adapted to direct the upper extremity of the weight 38 therein. The diameter of the upperportion of the cylindrical member 56 is preferably of a size slightly larger than the diameter of the upper portion of the weight 38, so that when the weight 38 rises sufliciently to enter the cylinder 56, water will be confined therein, and as the aperture 58, which forms an out let for the water, is comparatively small, the water will only pass through said aperture gradually and thereby form a cushion and relieve the frame or bracket 21 from undue shocks.

In order that the invention might be fully understood by those skilled in the art, the details of the foregoing embodiment thereof have been thus specifically described, but

A submarine sound producing signal including a gravity member for actuating the signal, said member being provided with rack teeth, a pawl adapted to engage the teeth, means actuated by the action of the water for operating the pawl to move the gravity member into an operative position, one of said teeth being provided with an in clined face adapted to be engaged by the pawl to automatically axially rotate the gravity member to displace the teeth and release said member to operate the signal, and means for rotating the gravity member after the signal has been sounded to place the teeth in an operative position with relation to the pawl.

35. A submarine sound producing signal including a gravity member for actuating the signal, said member being provided with rack teeth, a pawl adapted to engage the teeth, means actuated by the action or the water for operating the pawl to move the gravity member into an operative position, one of said teeth being provided with an inclined face adapted to be engaged by the pawl to automatically axially rotate the gravity member to displace the teeth and release said member, means operatively related to the gravity member for intermittently sounding the signal during its movement while released, and means for rotating the member to replace the teeth in an operative position with relation to the pawl when said member has substantially reached the limit of its movement while released.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 14th day of May A. D. 1907.
