Electrical Apparatus.

GROUND-PLUG FOR ELECTRICAL SWITCH­BOARDS.-WALLACE I. STOCKDON, Orange. Va. When properly applied to a switchboard to ground the main Circuit, this plug will operate an audible signal independ_ ently of the main electrical circuit and will continue to sound as loni! is the plug is in place. so that the operator will be notitled when throngh with a line and will be cer­tain to remove the plug aud thus ·avoid the grounding of a wire except when desired.

CENTRIFUGAL PUMP.-SAMUEL MATTSON. Brook· Iyn, New York city. The piston of the pump with Its Inwardly-projecting hub, is mounted to revolve in the cylinder. Tbe piston has a series of pockets, e&cb pro­vided with a curved bottom and an outlet-opening, the outlet.openings being in the rear wall of the piston, near the periphery. In the front wall of the piston is an inlet opening registering with the Inlet-opening of the cylin­der and communicating with all the pocketl'. The divi­sion walls of the pockets are reduced on curved lines ex· tending from the front wall to the hub of the piston. 'rhe pamp cannot be clogged by stones which have passed the piston.

MARINE BOILER.-fuRRY LAWSON. Jersey City, N. J. The boiler comprises a shell, within which is a return·llue. Spaced mud· drums extend longitudinally below the shell, and between the mud-drums)s a grate. Water-return circulating pipes connect the ends of the mud-drums with the shell. Sets of tubes extend from the mud· drums to tbe shell between the end circulating­pipes. the pipes and tubes forming a Ilre-box with the grate. A combustion-chamber at one end of thellre-box extends over the corresponding end of the retum-Ilue. Meau are provided for holding the retum.llue in posi. tion withm the shell. Worn-out tubes can be readily removed without disturbing the geueral construction of the shell or drums.

ENGINE.-PAUL O. E. BOUDREAUX, Theriot, La. The engine is an improvement in steam and air motors. It comprises essentially a shaft having a wheel furnished with sets of alternating teeth. Cylinders are l'rovided. arranged in pairs, one pair cnrresponding with each wheel. Pistons moving in the cylinders. have stems or rods engaging the teeth of the wheel Valves control the passage of the motive agent.

Mec·hanlcal Devices.

W A S H I N G -MACHINE. - SAMUEL PATTERS�N. Wilkes-Barre. Penn. 'l'his clothes· wasbing machine com­prises 8 body In which a presser. a rubber, and a rod are vertically and horizontally movable. A swinging con­nection is llrovided for the rod, presser, and rubber. A pin extends from the reciprocating rod into a slot· in an actuating-bar; and a crank has its wrist- pin_ engaging a slot in the bar. A �aring operates the crank. The presser and rubber can be removed whenever desired: By turning the crank the actuating.bar is reciprocated, thereby operatlnl! the preBLer and ru bber.

BASKET·MACHINE.-WILLIUI JACKSON. Traverse City. Mich. The invention relates to a basket-form for Dasket-making machineB. which form is held and turned so as to present all sides to the work. A stuh fhaft is mounted fast on the frame, and on the stuD.shaft a sleeve is mounted to turn, having a square portion on which th� sleeve slides and with which It turns. A brake­strap is provided for the sleeve. Two rollers are attached to the frame and engage the haAket-form at opposite sides of the axieof the sleeve. 'fhe basket-form is placed beneath the staple-driving mechanism, so that work can 00 placed on the form. The form is turned around in time WIth the movements of the driving mechanism, so tbat the several parts of the baAket can be fastened together.

COMBINATION METAL·WORKING MACHINE.­SAllUEL J. HUNGERFORD. Farnham, Quebec, Canada. The inventor combines a motor. a lathe, and a drill, with tbe object of economizing space and rendering the machine portable. 'fhe combined machine is cheap in Its construction and is ready for instant service in any place where steam or otlJ�r source of power is available. It occupies les8 Iloor-space than tbree separate machines, and requires less than the usual amount of shafting and belting. The machine is especially designed for use in railway-roundhouses, factories, mills, ships, and the like.

Rallway-Contrlvance ...

SWI'1'CH.LOCK.-LuTHER N. WYATT, Lexington. Ky. The purpose of the invention is to provide a device for t.hrowing and simultaneously locking switches. the arrangement being such that the switches cannot be dis. turbed except through the medium of the regularly-pro. vided lever. A stationary casinl( is used, formed with spaced shoulders, and recesses adjacent to the _houlder@. A switch-bar extension elides throne:h the casing, and a latch is pivoted between its ends on the extension and is sJidable with the latter through the casing. This latch is formed with heads adapted to enter tbe recesses in the C8Bing and is of such length that one bead will engage

CRANBERRY-GATHERER.-WILLtAll B. WATERS, Manomet, Mass. The device consists of a pronged scoop provided wi1h a screen and a handle. The prongs raise the vines or bushes sufficiently to prevent scooping up a great amount of dirt, as the berries are stripped by the prongs from the branches. When a quantity of berries has accumulated, the leaves, stems, and other refuse are picked out; and when this is done, loose dirt is sifted out by means of the screen. (7891) J. T.

fuND RAILING SIMPLIFIED. Sectorian System by an Architect. Edited and revh,ed by Fred'!,. Hodgson. 16mo. Pp. 02. Price $1.

This volume describes a novel method of finding curves, twists, wreaths, ramps and cuts for hand railing over an elliptical stait. This method of finding the lines and anl!les for stair railings does away to a great extent with the mystifying lines so necessary to build a hand rail by any of the old systems. A brief study and a little practice will enable the workman to understsnd the whole system.

THE COMPOUND ENGINE. By F. R. Low. New York: Power Publishing Com· pany . 1900. 12mo., pamphlet. Price 50 cen ts.

The editor of Power has done a wise thing In issuing tllis little monograph on cnm pound engines. It Is a subject which neressitates great clearness of expression and which must be illustrated by very clear diagrams. 'fbis result has been obtamed admirably in the present book, which is Illustrated with many diagraDlB. We commend it to all those who wish to get a thorongh un­derstanding of the compound engine.

Chemical calculations are fascinating, and there Is little real difficulty In working any problem if the rules are well understood. The volume before us is an adfillrable text-book, in whiCh new methods are described. There are many examples given, all of which can be solved by arithmetic or alg�bra. The book Is rather more exten­sive than any we remembar to have seen.
