SOUNDING APPARATUS:

SPECIFICATION forming part of Letters Patent No. 528,600, dated November 6,1894.

' Application filed July 5, 1894:. Serial No. 16,532. (No model.)

To all whom it may concern: 5

Be it known that I, CHARLES E. KIRTLAND a citizen of the United States, and a resident of St. Francis, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in In the drawings: Figure 1 represents an.

elevation of my apparatus partly in section on line 11 of the succeeding figure and positioned on a marine vessel ready for use, the view being from the bow of the vessel looking aft. Fig. 2 represents a plan view of the major portion of the apparatus partly in horizontal section. Fig. 3 is a view looking outward from the vessel and illustrating the position of a mark and float with relation to a lead when the latter is descending in the water. Fig. 4 represents a partly sectional detail view of a peculiar mark that consti I tutes part of my apparatusg'and Fig. 5 is a partly sectional viewillustrating a ratchet and crank that also constitute parts of said apparatus.

Referring by letter to the drawings A represents an angular arm having a horizontal outer end, this arm being preferably made from metal tubing, but in any event its outer deck-rod- D, and another stay rod G is utilized-to connect said arm and rail H of the vessel.

The arm and rods above specified constitute a frame that in practice extends outward from a side of a marine vessel, but when said frame is not required for use the rod-member G thereof is nnhooked from the vessel rail and the arm A and rod F swung upward out of the way. A

' While I have described one form of a folding frame it is to be understood that the same may be considerably varied in the matter of structural detail without departure from my invention, inasmuch as said frame must always be adapted to the vessel on which my sounding apparatus is employed.

Arranged on the deck of thevessel is a casing I or other suitable supporthaving bear ings for a shaftJ to which a drum K is made fast, and the inner end of a line-guide L is loose on the shaft adjacent to the drum. The shaft also carries a pinion M that meshes with a spur-wheel N arranged to turn on a conveniently located stud f, this gear-wheel beingcast with or otherwise rigidly connected to another pinion P that meshes with a gearwheel Q fast on a spindle gsupported in suitable bearings, the spindle being provided with a collar h against which a dial R is held by means of a thumb-nut i, said dial being gradnated in any suitable manner to indicate fathoms. The rotative speed of the dialis governed by the gearing above specified and a pointer S is arranged opposite the face of said dial. I

A pivotal brake-shoe T opposes the periph ery of the drum-flanges and a sliding bar U connected to the brake-shoe is controlled by a hand lever V, as best illustrated in Fig. 2. The brake shoe may be locked in Working position by any suitable means, and as one way of automatically accomplishing this result I show a gravity latch j that engages a notch in the lever-controlled sliding bar.

A ratch W is fastonthatend of the shaft J nearest the operator and loose on said shaft when the drum is to be rotated. A lugm o the plunger it engages a bayonet-slot in the handle and'by a proper adjustment 'of the lug in' theslot said-plungermay be held out of engagement with the ratchet W to prevent rotation of the crank.

Wound on the drum K is a line Y of wire cable or other suitable material that is run through the guide L, over the sheave C and down through the guide at that depends from the sheave-head. The line is also run through a mark, hereinafter specifically set forth, and against sheaves n that are supported on a float Z, the outer end of said line being in swivel-connection with a sounding lead Z of ordinary construction.

The line-mark referred to in the foregoing is necessarily in the form of a clamp that will rise and fall with the line between the float and the line-guard that depends from the sheave-head B, but which will otherwise yield to said line when the latter is running in either direction.

As a matter of detail the mark herein shown comprises a pair of angular plates joined together by links, an inturned end of each plate being provided with an eye for the passage of the line, and the latter also runs through said links, as is clearly illustrated in Fig. 4.

One of the clamp-plates is provided with a yoke 10 and a spiral-spring q connected to the yoke is joined to a head r on a screw 8 that turns in a post ton the other plate. From the foregoing it will be seen that the contraction of the spring tends to bring the clampplates toward each other against the line because of the yield of the connecting links, and the tension of the spring is regulated by the adjustment of the screw.

The float is preferably an air-tight sheetmetal shell presenting a flat surface in opposition to the line, and this flat surface facing the water said float has a good hold thereon.

In practice no heed is given to the amount of line extending from the drum to the lead when the latter, float and mark are at their greatest elevation as shown in Fig. 1, the dial being set to have the graduations thereon start from naught at the indicating point. The line being let out the mark will stand against the upper end of' the float and the latter will be over the lead, said line running free through said mark and on the sheaves attached to said float. As the line runs out the crank is unlatched from the ratchet on the drum-shaft in order not to endanger the operator, the latter regulating the rotative speed of the drum by means of the brakemechanism above specified. To wind in the line, the crank is clutched with the drum-shaft and rotated. The slack of the line having been taken up further winding of said line will cause the mark in clutch therewith to rise from the float, and as soon as said mark comes up to the line-guide d, depending from the sheave-head B, the graduation on the dial opposite the pointer will determine the depth of the sounding. The sheave-head shank being loose in its support there is always suflicient pivotal play to permit of the line running free in either direction or in other words there is no liability of said line binding in said sheavehead.

From the foregoing it will be seen that the operator is only required to watch the rise of the mark as the line winds up, in order to determine the depth of sounding by reference to the graduated dial and by means of the latch the brake may be set against the drum to hold the latter against rotation while the sounding is being noted.

One of the especial advantages of my apparatus is the fact that accurate soundings may be obtained by others than those skilled in the art, as the entire operation is purely mechanical, while at the same time said operation is materially facilitated and rendered less difficult than by the means ordinarily employed, and it is not necessary to slacken speed of the vessel employing said apparatus. It is also to be noted that I employ a float in connection with the lead-line, and this float is of material advantage because as it remains on the surface of the water immediately over the lead when the latter is cast, I overcome the necessity for carrying said line forward on a moving vessel to make a cast as has heretofore been a necessary procedure.

While I have shown and described a float having a flat surface and provided with sheaves for the lead-line, I do not wish to be understood as confining myself to this construction nor to any means for ascertaining the amount of line below the float, as it is possible to arrive at this result in a variety of ways.

Having thus described my invention, what I claim as new, and desire'to secure by Letters Patent, is-
