OTTO M. KNOBLOCK AND JAMES DUSHANE, OF SOUTH BEND, INDIANA.

souii nme errane'rusvented certain new and useful Improvements in Sounding Apparatus, of which the following is a specification.

Our invention relates to machines for taking soundings from vessels either at rest. or under way and it has for its object the production of a machine that will correctly show the depth of water at the place where the sounding is made whether the motion of the vessel is ahead or astern or if it is atvanchor.

It consists of such construction and combination of parts as are hereinafter more specifically described, and shown in the accompanying drawings in which Figure 1 is a vertical cross-section showing the various parts in their relation to each other. Fig. 2 is a horizontal cross-sectional view of the same. Fig. 3 is a view partly in section of the sinker or lead. Fig. 4 is a vertical sectional view showing the electric magnet applied to the brake lever directly. Fig.

5 is a diagram of the electric connections from the sinker through the battery to the magnet.

Like parts throughout are designated by the same letter or figure.

The working parts are inclosed in a box, I), whichis provided with a glass-covered opening, a, the use of which will appear later. Nithin this case is mounted a reel, E, upon which the sounding wire, F, is coiled. This wire passes from the reel, E, over a measuring pulley, D, thence over a carrying pulley,

C, downthrough an eye, B, at the lower end of a swinging L-shaped arm, A, and carries a sounding weight, 10, of special construction.

On the shaft of reel E is mounted a friction disk, G, which is clamped between two brake shoes, HH, which are pivoted toa block I, in the bottom of the casing.

The axis of reel E projects outside of the case and is provided with a crank, 20, by means ofwhich the wire Fmay be wound up. The crank may be clutch-connected with the axis 2 so as to engage it only while the crank is in use for winding up the reel.

To the outside of the upper arm of brake shoe H is secured a spring plate 6, through which passes a draw bar or rod K. This rod is provided with a thumb-nut, 7, which Specification of Letters Patent. Application filed January 2| 1906. Serial No 294.331.

bears against the outside of spring 6. Rod

K passes loosely through the upper ends of shoes H H and also the short arm of lever J. and is loosely secured thereto by 'a nut'or head. Lever J. is ful'crumed upon brake shoe H near the upper end. It is evident that by drawingup on the thumb-nut 7, these shoes H H may be brought into any desired degreeof closeness to disk G.

To the end of the long arm of lever J is secured a spring, L, the tension of which may be regulated by a thumb-nut, 8, as shown,

thus determining the degree of force with which brake shoes H H will clamp disk G.

To the same end of lever J is secured a short draw-bar, M, having a finger loop at itsouter end and a square shouldered catch, 0, which engages a latch, N. This latch N is flattened at the point of engagement and it forms the core of a solenoid, 1?, within which it is free to move. 9 is an anti-friction roller behind N, to facilitate its action.

is free to move longitudinally thereon by reason of the feather-key, 4, It is rotated from measuring wheel D through the worm gealrl, X and W. The shaft of W is provided wit a worm, o, and this engages and revolves gear wheel U and drum'T through their common shaft, 1. It will thus be seen that indicating drum, T, may be revolved in relation to measuring wheel D in any desired ratio of revolutions. rocker arm A by reason .of eye B swings with sounding line F to the right or left as the vessel may be going ahead or astern, it will through arm Q, and its'connection with drum T shift said drum to the left or right along its shaft, 1, without interfering with its rotation with said sh aft.

The surface of drum T is provided with circumferential gradua'tions marked with figures to indicate the true depth corre-' sponding to any given length of wire paid out in any given angular direction, i. 0., the

1 central line of figures record the length of wire paid out vertically while the vessel is lying still; the next row to either the right And since or left record the corrected vertical depth say 5 with the vertical.

that corresponds to an angular position of of figures may be supplied that will give the I correct verticals for any desired angular position of the measuring wire. It is evi.- dent that the angular'position of the wire'is dependent upon the speed of the vessel at the time the sounding is made, and that the correct depth is the perpendicular of a right angled triangle whose hypotenuse is the length of the sounding wire paid out.

The sounding wire is made up of two strands insulated from each other, the upper ends of which connect through a battery to the terminals of the solenoid .P, and the lower ends are connected with parts of the sinker as hereinafter described.

The sinker 10 comprises a body chambered at 10, provided with a threaded portion to receive a removable plug 12 to which. is soldered the terminal of wire 11 forming part of sounding line F. The wall of chamber 10 is also provided with an annular groove ,to receive the edge of a flexible diaphragm 16 which is forced through the opening in the lower end of the liodylO and sprung into said groove. Said diaphragm supports an inverted mushroom-shaped stem 14 the upper end of which extends into a cupped portion 12 formed in the underside of plug 12, but normally out of contact therewith. The terminal 13 of line F is secured to stem 14 the diaphragm serving to insulate same from the-body of the sinker, and the enlarged end of said stem projects from chamber 10 and clears the lower edge of body 10 by a short distance. A suitable plug 15 is em loyed to facilitate the passing of line F to t e interiorof the plug: The upper portion of stem 14 is, of metal, the portion 15 of said stem which extends below diaphragm 16 being of any suitable nonconducting material, such, for instance, as

glass, vulcanite, or the like.

. The operation is as follows :Assuming the sinker to have been wound up, draw bar, M, is pulled out until latch N falls behind. catch O, and holds lever J against the recoil of spring L. This releases reel E and sinker 10 plunges downward. As it draws wire F over measuring pulley, D, the rotation of the latter is transmitted through the worm gearing, a? and o, causing shaft IV with its drum T to revolve. As the operator looks through the window opening, a, he willsee from'the figures on the drum asthey pass just to what vertical depth the sinker has descended. the bottom, bulb 15 will deflect diaphragm 16 and stem 14 will be thrown into contact with plug 12, thus establishing an electric The second row .brake.

As'soon as the sinker strikescircuit through the wires, 11 and-13, and the electric current from the battery will energize solenoid, P, which will at once lift its latch-shaped core out of engagement with catch 0. Spring L will then become effective and will through lever J instantly set brakes H H, upon friction disk G, thus automatically arresting the further delivery of wire F. A glance through opening, a, will at once show by the figures on the drum, T, the exact depth where the sinker touched 'the.bottom. .To get additional soundings the sinker is merely lifted clear of thebottom, when it is again dropped and a new reading will show on the drum. Further, if sufficient wire has been paid out so that the sinker drags upon the bottom the shifting of the drum through the swing of the rocker arm, A, will show the variation-in the depth due to the inequalities of the bottom; It will then give a continuous reading.

In Fig. 4 we show a slight modification of our improved sounding apparatus which consists in operating the brakes H Hby means of a solenoid P the'core' N of which is directly connected to brake lever J. In operation the reel E is released in the manner heretofore described and as soon as the sinker strikes the bottom and closes the circuit, solenoid P is energized whereupon its core will draw upon lever J- and cause -the brakes H H to beset.
