To all whom, t may concern: 5

Be it known that I, JOHN PAOLI, a citizen of the United States, residing in the city of:-

Hoboken, in the county of Hudson and State of New Jersey, have invented new andfuseS fnl Improvements in Binnacle-Oompasses, of

which the following is a specification, 4,

My invention relates to binnacle-compasses g-l and its novelty consists in the cons truction and ladaptation of the magnet-chamber andY its appurtenances, as will more fully herein-k after appear. 1

Heretofore in binnacle-compasses thercorrectional magnets have been placed upon trays within the magnet-chambenfwhich has been provided with an aperture only atvor near the bottom, so that the removal or replacement of the magnets and their adjustment within the chamber has been la matter of difficulty and inconvenience. the heeling-magnet, which should be vertically adjustable along the central axis of the chamber, has been difficult to put into position and move on account of the fact that the chain from which it depends has been passed, over fixed bearings above the tube in which it reciprocates, and taking it out has necessitated the removal of a considerable portion of the structure or of a number of itsparts.

The object of my invention is toobviate the difficulties above recited, and this I, do by the following means: I place the magnets within magnet-tubes, in which they are se-` curely locked by simple means. The tubes are supported on frames which in turn Vare supported on trays. These trays are circumferentially adjustable and are mounted upon screws, whereby they may be moved Vertically at the will of the operator by means of a milled head attached to a beveled gear which j Likewise 'h2 of thebevel-gear h3.

issupported onabracket which is adapted ',to'begoscillated in a bearing secured to the wall o f the magnet-chamber.

composed of two pieces, each of which is provided with an ear or stop, so that its rotation beyond the plane of the top of the wall of the magnet-chamber is prevented. -K

In the drawings, Figure l is a central verticalsection of, a binnacle-compass magnetchamberprovided with my improved devices. Fig.;a is a detail view in cross-section through one. of the magnet-trays, showing a suitable relative construction of the two parts thereof by which'th'e magnet-carrying part may be adj usted circumferentially upon the other part and be held fixedly in its adjusted position. Fig. 2 is a top plan View and partial sectionfof the same on the plane ofthe line 2 2 in Eig. .1. Fig.` 3 is acentral vertical section in a plane at right angles to the sectional plane of Figal, and Fig. 4 is a top plan View and partial section" on the plane of the line 4 4 in FigLS.

In the drawings, c is the magnet-chamber, of the usual inverted conical form and provided with an upper horizontal wall c and a suitable lateral aperture closed with a door c2. Placed vertically Within this aperture are twol screws s and s', rotating in suitable bearings and each actuated, preferably, by a handie hor milled head h', secured to the shaft There are two magnet-trays, one, m, provided "with a threaded sleeve m and adapted to be moved vertically upon the screw sand the other, n, provided with a similar threaded sleeve n andadapted to be moved vertically upon the screw s. The tray m consists of two ann ularpieces-a bottom piece fm2 and an 'adjustable upper piece m3, held within a fiangeV upon the bottom piece m2,l upon which it is adapted to rotate, set-screws m4 serving to keep these pieces in their positionsafter` adjustment in spiteof.,anyordinaryjmeans Iof displacement.y Similarly/'fthe Stray faconsists of a bottom piece n2 and anjadjustable upper piece n3. Fig. lt'shows asuitable construction of the tray m by which its upper part may be adjusted circumferentially on itsl lower part, and the means for this purpose of the tray 'n may be similar to that o said tray The bracket is m, for which reason it is not deemed necessary to show both of said trays in detail. The invention is not restricted to the particular construction of tray shown in the drawings, as any suitable construction thereof capable of accomplishing the purpose stated may be employed without departing from the spirit of the invention. Upon the adjustable upper piece m3 is mounted a framef, adapted to carry three or more horizontally-placed hollow tubesf', which are permanently closed at one end f2 and temporarily closed at l(he otherend by means of a doorf, Fig. 4, swung on a jack-knife hinge. These tubes contain the magnets, made of fine rods of suitable metal, and are mounted in two parallel series. Similarly upon the adjustable upper pieces n3 is mounted a frame e, adapted to carry two parallel series of horizontally-placed hollow tubes permanently closed at one end and temporarily closed at the other and adapted to hold the magnets. The series of tubes mounted upon the tray n are closer to the center than those mounted upon the tray fm, and as the trays are moved up and down they pass each other, the tray n passing through the aperture in the tray m provided for the purpose. The tray n is vertically guided by the walls of the heeling-magnet chamber. The tray m is similarly vertically guided by the upright rod 71:, which may, if deemed desirable, be graduated.

The rotation of the proper milled head will cause the corresponding rotation of either the screw s or the screw s and the resulting elevation or depression of the tray m or n. The proper number of magnets having been put into position, they can thus be independently adjusted by the operator vertically and stopped at any desired point,said adjustments of the magnets and their trays being relative to each other and to the tube d, which contains the heeling-magnet. They can also be adjusted centrally by turning the trays until they are both opposite the door of the magnet-chamber, and the plates m2 and 'm3 or u2 and n3 can be put in the desired position by hand and fixed by the set-screws.

I believe I am the first who has devised any means whereby the magnet-trays within a magnet-chamber could be placed in the same horizontal plane. This adjustment has long been sought for, but until my'present device has not been secured.

The heeling-magnet tube d passes centrally down through the axis of the chamber c. Within it is the heeling-magnet d', suspended from a chain cl2. This chain is adapted to pass over a pulley or sheave p, so that the axis of the chain coincides with the vertical axis of the chamber c. The pulley or sheave p is provided with a horizontal shaft p', supported in a bracketwhich is adapted to oscillate in a bearing 132m the upper wall c' of the magnet-chamber and are provided with stops p3 and p4, which prevent its oscillation in a downward direction farther than to such a position that the chain is in the proper place. The position of the chain at its out-er end is fixed by a set-screw p5. rPhis device affords an easy access to the heeling-inagnet and its tube, secures the proper position for the magnet when in place, and is simple and economical in construction. j

I do not limit myself to this precise method of securing the chain in place. It will of course be understood that equivalent meanssuch as, for instance, winding the chain on a reel provided with a brakemay be employed without departing from the principle oi my invention.
