ELECTRJOMAGNET.
To all whom it may concern devices andfinds' a very important embodi-v ment' in electric bells or other electro-mag nets in WhlCll' vibrating armatures are employed,-though thereare' characteristics of my'mvention-which will 'be of service in other electric devices and I therefore do not wish toz liniitrmyself to other electromagnetic devices that employ .vibrating armatureso: 5- t nMyinvention has for one-'of its objects the provision of an improved framework for the spool structure of theelectro-ma netic device -whichi may readily be as'sem led with such spool structure, and'an electro-ma neti'c device made inaccordance with this feature of. my inventionincludes its spool structure, and a framework between opposite-sides of which the spool structure is dis posed, and which opposite framework sides are in engagement with the ends of the spool structure, each spool structure end and the framework side enga ing the same being of formation to enable t e spool structure and the-sides of the framework between which 1 it is disposed to be slid into engagement, in
the assembly of the parts, thereby to position the spool structure in the framework Another feature of my invention relates to those electro-magnetic devices which employ spools in pairs and which spools operate to supply a magnetic circuit common thereto with flux. It is the object of this feature of my invention to eliminate 'the screws which have hitherto been employed for uniting the heel pieces of the electromagnets with-the'cores of their spools and by this feature of my invention I improve the mechanical assembly of the spools of an electro-magnet and the cores of such spools. An electro-magnetic device made in aocordance with the preferred embodiment of the present feature of my invention includes a pair of spools and cores therefor each having magnetizable portions terminating ad- Specification of Letters Patent.

' I will explain my inv ention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which- Figure .1 is a view in elevation, partially in section, of a bell structure 'embodyingthe different features of my invention; Fig. 2 is a sectional view-on line 2 2 of Fig. 1; Fig. 3,-is-a sectional view on line 3 '3 of Fig. 1; Fig. 4 i a sectional view on'line 4 4 of 5; Fig. 5 is a sectional view on line 5 5 of Fig. 1; F ig. 6 is a view in perspective il1ustrating some of the structural characteristics; Fig. 7 is a detail view of a portion of the fra-meworlqand F 8 is a plan view of v the fragment shown in Fig. 7. 1
Like parts are indicated by similar char: acters of reference throughout the different figures. -V
As I have embodied the invention, it in clude two spools 1 1 each having a core formed of a plurality of arts, these.parts desirably being in the orm, of laminae, Laminae 2 comprising a part of each of the cores terminate adjacent the ends or heads of the s 001s. Each core includes a sepa rate additional lamina 3, the laminae 3 formbalance of the cores formedof the laminae 2 throughout theinterior ofthe spool bores so that firm mechanical union i's' estabhshed' between the two cores of the adjacent pools? When-:the laminae-'3 are' made of magnetiz able materiahsthe intimatecontactthat is :ifiordedbetween :the same and the balance of-the-core portions serves to cause'all of the laminae wvithin each spool bore .to :be well included in" the same magnetic =circuit, the integral portion 4 uniting the laminae portions 3 serving-.tmjoin the cores in awell established in'agnetic- :Tcircuit. -Hithertothe cores of the spools :were joined= in the same magnetic circuit by means"of'=heel pieces that were held; in :contact with 5 the cores by means of'-screws-,:'a construction that gave rise to i much magnetieureluctance at t'he invention overcomesu' Thei free poles bf the composite' core which-*Lhavesupplied for the two-spools face. the armature'structure fi, this armature screwsya defect which the structure'of "Hr-'1 i structureaincluding a leaf extension fi that,
terminates ,in a tongue'7*'-whicli 'is received in the groove-8 of the armature -support' fi), this-armature support having lateral extensions '10 for thepurpose of confining the armature to proper plane of movement. A- leaf spring '11'-is supplied, in'addition to the-"armature support, for= the:purpose of swinging the armature in one direction,-"-the magnet operating to swing the armature in the reverse direction; This leaf 1 spring, which is providedin addition to the armature support 9, serves to bottom the tongue 7 in the groove that'receives 'itwhereby the armature and its 'mountingare held-in en'- gagement, the spring 11 thus'hav ing a new functioniadded to 'it.- The-typev of hell shown is a direct 'c urrentbell including contact's'12 and 13 that are brought into-en gagement by the spring 11 when the magnet is denergized and which serve, when en gaged, to close circuit through thefspools for the purpose of attracting the armature in opposition to the spring 11. I do not wish to be limited, however, "to the embodimentof my invention in direct current bell structures. The spring 11 may be anchored inany suitable way at the end opposite to that end which is connected: with thearmature. IKhave shown a screw 14 whose stem has been threaded through an opening in the spring-11 and which stem has an annular groove cut therein adjacent thescrew 'head toreceive the spririg.- The tension of the spring may be determined byjturning the screw and the tension which has been thus secured may be maintained by means of alocknut 15 "The remaining feature of myinvention resides in the provision of a framework for the spool structure of an electro-inagnet irrespective of the purpose to which such electro-magnet is put. In practising this feature of my inventionthe opposite sides 16 17 of the framework are slid into engagement with the ends-of the spool structure;
(which spoolstructure may contain ronejor more spools) the core portion ofthe spool structure desirably projecting beyond the spool structure and being Slldfil'ltO engage-- ment with the sides 16 and 17.01: the framework whereby the spool structure -is positioned within the frame work. The-sides 16 and-17 of the:frameworkare-provided with apertures that receive theprojecting core ends of the spool structure but-'Iido "not wish tobe limited to the formation :ofQtheframework and spool structurejth'at enables the spool structure and framework to be slid into engagement} when-parts areubeing assenlbld'. As I have preferably embodied thein venti'on; the framework side-:lla-is separatelyformed from the balance of the framework and when thusl separately z-formd it. is
preferably provided at one end with means whereby it y m ok engagement-with a djacent,- portion of the franieworkwth framework side 17 being illustrated' With-ta hook 18 that-is-adaptedito engage an offset rib 19 struck up 'from the portfongqof'the frameworkadjacent" to: the ::hook -*18,- this hookand rib being initially engaged 'whereafter the other end of the framework side.
17 is held in'engagement with an adjacent framework portion by means ofa screw 20.
The screw20 is a. convenient means for :unit
ing an end oftheframework'side l7' with an adjacent portionof the framework, but I do not wish to be limited thereto.
The framework. side 17 is provided i apertures 21- through which the -core :ends of the spool structure may project into proximity with the armature 5. Where the framework is in electrical connection with a terminal of the spool winding,a twinwasher 22 surrounds the core ends that project through the openingsifll and insulate the IIRIHOWOXkSidG 17, from the plate 23 that is secured to the spool structure as indicated in Figs. 1, 3 and 4: and which plate is pro vided with an arm extension 2% that con stitutes a support for the back contact 13.
While I have herein shown and "particularly -described the preferred-embodiment of my invention, I do not wish to be limited to the precise'details of construction shown and particularly describedas changes may readily be made without departing from the spirit of my invention."
it h Having thus described my invention, I ing three sides,
claim as new and desire to secure by Letters Patent the following 1. An electromagnetic device including a spool structure Whose ends are provided with projections; a frame work portion having three sides, which is recessed to receive and havesliding relation with the projecting formation at one end of the spool structure; a framework portion constituting a fourth side of the frame work and recessed to receive and have sliding relation with the projecting formation at the other end of the spool structure, there being hook connection between one end of this fourth side and an outer one of the three sides of the first aforesaid framework portion; and a screw joining the remaining outer side of the three sided framework portion with the remaining end of the fourth side of the framework.
