T0 all' 'wlwm ?It may tancem:

Be it known that I, DAVID J. HAUSS, a citizen of the United States, residin at Aurora, in the County of Dearborn and tate of Indiana, have invented celtain new and useful Improvements in Electromagnets, of which the following is a specification.

My invention re ates to im rovements in electromagnets to be employe for] the various uses to which electromagnets are ordinarily applied. f

One of its Objects is to provide a compact magnet of eflicient form,'and not liable to injury.

Another object is to provide an improved arrangement of parts and means for assembling whereby the parts are readily assembled, firml secured together and at thesame time readi y separable for reairs.

Another object isto provi e means for assembling or separating the parts without disturbing or injuring the magnetic coil.

It further consists in certain details of form, combination and arrangement, all of which will be more'fully Set forth in the description of the accompanying drawings in which Figure 1. is a. central -vertiCa l Section through my improved. magnet on line m of Fig. 2; F ig. 2. is a plan view of One end of the magnet. Fig. 3. is a plan-view of the opposite end of the magnet. F ig. 4. is a section through the same On line' 'v 'v of Fig. 2., and illustrating a modification of the assembling mechanism. Fi 5. is a side elevation of one of my improvec magnets employed to Support an arc lamp. Fig. 6. is a plan view of an electrically' Operated bell actuated by one of my improved magnets.

In the aceompanying drawings A represents a central Core piece of magneti'c material. Tightly fitted to the rear end of the Core Apreferably by a drive fit is a disk or washer of magnetic material B. The disk B is of sutficient thickness to Carry economic ally themagnetic fiux. A light spool'C of insulating material is wound with a coil of insulated wire Dand slipped over the core A. The spool C and coil D are heldin place upon the core A by means. of a disk Or washer E of non-Inagne'tic material fitted to the forward end of core A. The terminals d cl' of the coil D are preferably passed through openings b b' in the disk B, which openings are lined with washers b of insulating materiaL- F represents a head, preferably of porcelain, hard rubber Or other insulating material which is provided with binding screws f f' adapted to be electrically connected at -oneend to the terminals d d' of the coil D,

and at the opposite end to be connected to the live wires supplying current to energize the magnet.

G represents an insula-ting plate preferabl interposed between 'the head F and the dis B, and end of core A.

H represents screws threaded into disk B to lock the head F to the disk B.

I represents threaded holes to receive screws by means of which the magnet may be attached to any objector mechanism deslre The head F has threads f on the exterior which are engaged by the threads of the ut or collar K. v

v L 'represents a tubula' Or cylindrical housing of magnetic material which is re- Cessed on the interior to receive and closely fit the periphery of the disks B E and having a shoulder or ofi-Set Z against which the disk B seats. As shown in Fig. 1, the

head k of collar K s'eats upon the end of l Sleeve L and serves to draw the core A and disks B E into Sleeve L and to lock them firmly therein. As shown in F ig. 4, a cylin- (lrical shell M is interposed between the head of collar K and-the end of Sleeve L.

The magnetic path is from the armature Or magnetic object N through core A, disk B and Sleeve L to the armature Nthe Sleeve L Serving as one pole of the magnet and the core A as the other pole. The Sleeve L also The mechanism herein illustrated and described is capable of considerable modification without departing from the 'principle of my invention.

Having described my invention, 'what I Claim is 1. In an article of the Character indicated,

a core of magnetic material having a nonmagnetic disk attached to one end, a magnetic disk attached to the o posite end, a coil of insulated Wire encirc ing Said core, and a tubular housing of magnetic material recessed upon the interior to receive Said disks and to form a shoulder against which said disk of magnetic material seats and is locked When the parts are assembled.

2. 111 an article of the Character indicated, a Core of' magnetic material .having'a disk of non-Inagnetic material attached to one end and a disk of magnetic material attached to the opposite end, a coil of insulated Wire eucircling 'Said core between said disks, a head attached -to said disk of-magnetic material and provided with external threads, a Sleeve of magnetic materialrecessed upon its interior to receive said disks and to form a shoulder against which said disk of magnetic material seats, and a collar threaded to Said head and Serving to draw said core and disks into said Sleeve.

3. In an article of the Character indicated, a Core, a disk of magnetic material attached to one end of said core, a disk of non-magnetic material attached to the opposite end of said core, a coil of insulated Wire en- Circling Said core between said disks, said disks of magnetic material having recesses for the passage of the terminals of said coil, a' head attached to the end of said core carrying said disk of magnetic material, a

Sleeve of magnetic material recessed upon the interior to receive said disks and to form a Shoulder against which said disk of magnetic material seats, and means engagin said head and Sleeve to lock Said core an disks' within said Sleeve.

4. In an article of the Character indicated, a core, a disk of magnetic material attached to One end of-said core, a disk of non-magnetic material attached to the opposite end of said core, a coil of insulated Wire encircling said Core between Said disks, said disk of magnetic material having recesses for the passage of the terminals of said coil, a head of insulating material attached to the end of Said core carrying said magnetic disk, said head being provided with binding posts to connect the terminals of said coil with the live Wires; and With means for attaching said magnet in position for use, a Sleeve of lnagnetic material recessed upon the interior to receive Said disks and to form a Shoulder against which said disk of magnetic material seats, and means engaging Said head and Sleeve to lock said core and disks Within said Sleeve.

In testimony Whereof I have hereunto Set my hand in presence of two Subscribing Witnesses.
