Specification of Letters Patent.
Patented Feb. 3, 1914.
Application filed January 11, 1913. Serial No. 741,426.
the following is a specification, reference being had to the accompanying drawings,
which form a part hereof.
This invention relates to improvements in electromagnetic relays.
The invention seeks to provide a special mounting of the relay armature whereby it is enabled to make reliable electrical connection with three stationary contacts 10- catcd on the same side of the armature even though such contacts may be adjusted at different distances from the magnet coil or. coils or at difi crent distances from the stops or contacts on the opposite side of the armaturc.
The invention also seeks to embody the arrangement just specified in a relay in which the contact operating parts shall be strong and durable in structure and not easily subject.- to injury or derangement from rough handling. i'or this purpose springs are dispensed wit in constructing the contact parts and unyielding, rigidly fixed contacts are employed.
In the accompanying drawings forming part of this specification, and in which like reference numerals designate corresponding parts in the several figures, the invention is shown in its preferred form and in a nnulification.
Figure is an end elevation partly in section of a relay cn'ibodying the invention and having tlm front and three back contacts. Fig. 2 is a side elevation partly in section showing part of the relay illustrated in Fig. 1. Fig. 3 is a plan view showing the invcntion embodied in a relay of another form and having a floating armature colipcra'ting with three front and three back contacts. Fig. l is an elevation, partly in section, of the relay shown n Fig. 3. Fig. 5 is n diagram showing the circuit connections f the relay shown in lfiigs. and 4'.
Referring now to the invention as shown in Figs. 1 and 2, the relay is shown as providcd with three front and three back contacts, stationary and unyielding, the armature having the capacity, when in its back I position,
\ to make reliable connection with all three back contacts, and when lIl its front position, to make' reliable connection with all three front contacts. Fixed to the base 1 and projecting upward between the magnet coils i and 3 is an arched post l carrying from and back contacts 5 and 6. Supported on the base and at the sides of the magnet coils are two back contacts 7 and 8 and two corresponding front contacts of which only contact 9 is shown. These contacts are in the form of rigid screw studs and are held firmly in place by check nuts. The armature 10 has a rigid body portion and is provided with three rigid contact carrying fingers which project between the pairs of front and back contacts. ll. is a double trunnion having two vertically alined journals l2 and 13 which turn in bearings 14 and 15, fixed to the armature, and two horizontally alincd journals 16 and i7 which turn in bearings carried bya U-shaped bracket 18. This bracket is pivotally supported at its lower end by bearings 19 and 20. 21 is a retraclilc spring for the armature.
By the construction described, it will be seen that the armature is free to carry its contacts separately and in turn, in any quence, against their stationary comacts on the sameside. and that the armature, there fore, readily adjusts itself to coincide with the plane defined by the three front contacts or withthe plane defined by the three back contacts. even though these planes may he 'ariously inclined to each other. The j bracket 18, with its horizontal journals, provides one horizontal axis and the trunnion i ll with its horizontal journals 16 and 1.7
provides another horizontal axis and with its vertical journals and 13 provides a vertical axis upon all j armature may move to adjust itself in'the manner described. In so adjus ng itself the armature is frce to fulcrum on the first contact it mccls and so tilt to meet thc other two contacts. If one of these latter two confacts is nearer than the other, then it fulcrunis again on the first two contacts it meets and so tilts to mcct the third contact and rests against them all. Thus, although the armature may meet tl contacts on the same side successively, its movement is not stopped by the first or second contact it meets but such mov-anent continues until of which axes the the armature it; has the force acts along lines ot'yarying location in of said con- 7 tacts. 'lhus, the armature contacts are sure order to cause the armature to assume its re to come to rest against all of the back conquired position. On the contrary, in the ap taets or a ainst all of the front contacts 1 plicants invention, the resultant nnigneto- In Figs. 3 and at the magnet 22 is secured motive force acts along a line which has a to av plate 23 supported by three similar fixed location relative to the relay, yet the action is such that the armature is enabled to meet a plurality of contacts located on the same side of the arn'iature successively, in any sequences so as to rest against them all 1e ari'nature siinult'ancously: meets The armacontacts iii posts, of insulating material, 24, 25 and 26 (the latter not: shown) which are secured to the ase 27.
