HARRY LEONARD WAITE, OF EGREMNT, ENGLAND.

SOUNDIN Gr-MAC'HIN F1.

To all 1071011@ it may concern Be it known that l, HARRY LEONARD VVArrn, a subject of the King of Great Britain, and residing in Egremont, in the county of Chester, England, have invented certain new and useful Improvements in and Relating to Sounding-Machines, of which the following is a specification.

The present invention relates to sounding machines of the type in which a cord or cable, attached to the lead or sounding device, is wound upon a rotatable drum provided with operative means and a frictional device by means of which the drum can be allowed to run so as to pay out the cable under the pull of the lead, or alternatively, the drum can be rotated so as to hoist the lead. Such machines are usually provided with an indicating` device whereby the length of cable unwound from the drum is shown, and the object of the present invention is to provide an improved igdicating device for sounding machines of the type referred to.

I have illustrated a sounding machine embodying my invention in the accompanying drawings, in which- Figure l is a front elevation in part section, Fig. 2 is a side elevation, Fig. 2a is a view of the upper end of bar H showing more plainly its graduations h2. Fig. 3 is a plan, and Fig. e is a detail view of a modification of the indicating device. Fig. la is a side and end view of bar H showing the location of graduations 71,2.

The sounding machine illustrated, which is selected as a typical form in order to show the application of my present invention to machines generally of this kind, forms the subject matter of my concurrent application for a patent of the United States, Serial No. 7 82320, and the construction may be described briefly, so far as is necessary in order to understand the application of my present invention, as follows The cable or cord carrying drum A is mounted loosely on the shaft B carried in bearings on the main frame C. The shaft may be rotated at will in the direction which hoists the lead by handles applied to the squared ends b5 and bc, or by the electromotor M with its controller m1, through the train of spur wheels m3, m4 and 791, of which m4 is mounted slidably on the stud m5 so as to be disengageable.

712 is a ratchet wheel fitted on the end of Specification of Letters Patent.

the shaft B and provided with a holding pawl b3 which prevents the shaft from turning in the direction which lowers the lead.

D and c1 are friction flanges feathered on the shaft B on opposite sides of the drum A and adapted by axial pressure to frictionally couple the drum to the shaft, this pressure being applied by the hand wheel F screwing on the end of the shaft B and engaging with the end of the sleeve E, which is integral with the flange el. This sleeve is journaled in the main frame C and itself forms a bearing for the shaft B.

Tt will be understood that when lowering the lead, the shaft B is held by its ratchet wheel 712, and the frictional grip is relaxed and regulated by the hand wheel F so as to allow the cable to run out at a suitable speed or to arrest it at will. Tn order to hoist the lead, the drum and shaft are coupled with a suficient grip by screwing up the wheel F, and the shaft is then rotated by hand or by the electromotor.

The indicating device, which forms the subject matter of the present application, comprises an indicating bar H mounted so that it can slide axially in the main frame C, and gearing articulating the bar to the drum so that the lineal movement of the bar is proportional to the number of revolutions made by the drum.

A worm screw G, (see Figs. l and 3), is mounted freely on the shaft B, and is rotated by means of the cranked arm g which engages with a hole in the side of the drum A.

A worm wheel g1, Fig. 2 mounted on a vertical shaft g2 arranged at right angles to the shaft B gears with the worm screw G. The shaft g2, mounted in a bottom bracket g3 and a top bracket g4c suitably carried from the main frame C, has fitted at its upper end a bevel spur wheel g5 gearing with a bevel spur wheel h1 fixed to one end of a spindle 7b2; the other end of this spindle carries a gear wheel 71l which gears with rack teeth cut on the bar H. The bar H which is arranged to protrude through its guide 7e3 carried by the main frame will obviously indicate by its position the length of cable unwound from the drum and it is graduated accordingly as shown at 7112,' in addition to graduation marks adapted to be read visually, the bar is made with notches or projections at various points along its length, so that the length of cable unwound may be ascertained, eren in the darli, by passing the hand along the part of the bar which protrudcs, and feeling and counting the nuinber oi notches or projections so exposed.

Tn addition to giving the length of cable paid out When the lead is lowered, the in dica'ticn afforded is a guide to the operator in hoisting so that heV may not over-Wind the cable.

The provision of graduations Which can be telt has the advantage that the indication can be ascertained under Weather conditions which niight render it inconvenient to inspect a dial, or even during darkness Wl ich would otherwise necessitate a lanip.

ie bar 'ifi is preferably inade comparatively inassic, as it found to be useful in resisting sudden changes in the speed of the drinn, in paying out the cable, due to the rising and falling of the shin; when the ship rises, the increased drag of the descending lead tends to accelerate the drinn, which niay then overrun the cable when the ship descends, thus risking fracture of the cable. The inertia effect of the coinparaf tive/l5T inassire indicating bar lvl, in conjunction with the considerable friction resistance in the transmission due to the Worin drire, has a steadr ig tendency on the drum, and reduces the risk of losing the lead by :fracture ot' the cable.

ln the modification shown in Fig. d, a screwed bar il is provided in place of the tooth al racl: bar lhe screwed bar H is carried in suitable guides and a lixed pin ,7i/'5, engaging in a groove it in the rod H, prevents the latter from turning but allows it to slide freely up and down. fr gear Wheel fr rotatably inounted in the bracket gt forins a nut for the rod H', and a Coates o 'this patent may be obtained for five cents each, by addressing screwed extension on the boss of the gear Wheel 7L is iitted with the nut 7L which bears against the under side of the bracketl gAl and prevents axial nioveinent of the wheel it. The gear Wheel 7i gears with another gear Wheel g/5 iined to the upper end oit the shaft g, which is geared to the druni A as before described.

lt is obvious that the bar H will, as in the case of the bar H, indicate by the length of it which protrudes, the amount oi" cable unwound from the druiu, and it is notched, as in the case of the bar H, or the screnv threads themselves niay afford the necessary indications adapted to be counted by the sense of touch.

Haring nouv Ytuily described my invention, l declare that what l claini, and desire to ,ecure by Letters ,Patent is :u

lrn a sounding machine comprising in coinbination a traine, a inain shaft, a cable druin loosely mounted thereon and haring a cable positively attached thereto, ineans for drivingsaid cable druin, a notched indicating bar adapted to protrude through said traine ar d adapted to inove axially thereto, a Worin gear rotationally mounted on said shaft and positively coupled with said druni to be driven thereby, and reduction gear interposed between said Worin gear and said notched bar adapted to more the latter axially in a direction corresponding to the direction of rotation said druin, substantially as described.
