tion.
My invention relates to relays, particularly relays adapted for use in telephone systems, the object being to produce improved and simplified construction and arrangement which will decrease the size of the relay without detracting from its efficiency.
In some instances, for example, in private branch exchange installations, very little 29 space is available for the telephone installation, and it is a very great convenience and some times a necessity to have very small so that a sufficient. number thereof can be installed in the available space.
such simple construction and compact arrangement that its size can be very greatly reduced Without. the least-decrease in etliciency of operation.
shape of the contact clips which I employ.
I provide a cylindrical core 1 which forms the sole support for all the various relay parts. The energizing winding 2 is mounted on the center of the core between the heads or end plates 3 and 4 of insulating material. The armature 5 is in the form of a fiatstrip, preferably of mild steel bent to the shape shown, the main part thereof eX tending over the coil substantially parallel The rear end extends down wardly and then horizontally, the horizontal part 6 being grooved to fit the core section 6', the whole armature structure being held in place by the screw 7, securing the end 6 to The front end of the armature extends downwardly and then horizontally forwardly, the horizontal part 8 forming the pole of the armature, there. being normallv sufficient spring tension in thearmature to hold the part 8 a sufiicient distance In the accompanying drawings which show from the core section 9 which forms the pole of the core. The part 8 extends a distance beyond the end of the core section 9 and carries a contact point 10.
Mounted below the core section 9 is a contact spring 11 formed of flat sheet material bent to the form shown, the body part thereof being clamped between the insulating sections 12 and 13 by means of a screw 11 which threads into the section 9. The insulating block 12 has its uppen face grooved out to fit the cylindrical core, and the rear edges of the insulating parts 12 and 13 and oddhe contact franae are square and rest against the insulating nead 3, thus holding themselves rigidly in position. The front end of'thecontact frame extends upwardly and then horizontally forwardly, the
the clip arms of the first and third plates appearing at the left side and the clip arms the clip plates to securely clamp them together and to the core section 6. The feet a 22 of the rclip plates and thefrontedges of the insulating strips and the insulating block abut against theinsulating head 4 of the coil and so assist in maintaining the. correct position of the clips. A'clip arm 28 also extends si-dewardly from the contact fraine 11' at the front of the corepand this clip arm is shown connected with the cliparm 23 of the lower clip plate by means of conductor 29 which passes through openings in the heads 3 and a. It will be noticed that there is no insulation shown between the screw 27 and the lower clip plate, and this clip plate is, therefore, in electrical contact with the core and with the armature. 23 of the first and second clip plates are shown as connected with the terminals of the energizing coil. Thus to connect the relay in circuit, it is necessary only to connect the various conductors with the contact clip arnis 21.
The relative dimensions-of the insulating v heads 3 and a and of the clip plates is such that the contact clip arms lie entirely Within the insulating heads so that when the re" are placed side by side with their insulating heads in engagement there will be no danger of electrical contact between the contact clip arms. The relays may be supported train common mounting plate or bar 29. The rear end 30 of the core 18 threaded and passes through thercornmon supporting plate 29',
insulating bushing 31 being inserted between the core and supporting bar to insulate the core therefrom, a clamping nut 32 serving to clamp the core rigidly in place. Below the core opening, a rectangular opening 33 may be provided in the plate through which opening the clip ends 21 may extend, and to prevent contact between the supporting plate and the chi ends the insulating strips 25 are made wider than the clip plates inorder to overlap the plates, the width of the insul ating strips being preferably equal to the width of the opening 33 so that the sides oi the opening will also assist in holding the insulatlng strips in proper alinement and position.
It is evident that a relay'built in accordance with my invention comprises a minimum number of parts and requires'very lit- 'tle laborin the manufacture of the parts and in the assembly thereoii The parts being so simple and :t'ew, the size of the relay can Contact clip arms be i ery greatly reduced. Although the size for' the relay is reduced the etiiciency is in no Wise impaired, and l find that the action in operation of a very small reli ij 'hhilt in ac- 'cordan'ce with my relay is justas strong and efiicient as that or larger relays in the prior art. The cylindrical pole end 9 and the flat armature pole end 8 seem to cooperate to cause concentration of the lines of force to produce a stroiig inagnetic field and torque.
Many modifications in theconstruction and arrangement could of course, be made which would still remain within the scope of my invent-ion, and I, therefore, do not wish tohe -limited to theparticular arrangement which I have shown and described.
I desire to secure by Letters Patent the following claims:
