SOLENOID AND SPOOL-MAGNET.
SPECIFICATION forming part of Letters Patent No. 451,308, dated April 28, 1891.
(No model.)
Original application filed March 20, 1 8 90, Serial No. 344, 61 7. Divided and this application filed July 2 9 18 90. Serial No. 36 0, 31 6.
To all whom it may concern:
Be it known that I, HARVEY S. PARK, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Solenoids and Spool-Magnets, of which the following is a specification.
This specification is intended as a division of an application filed by me March 20,1890, and numbered 344,617, and it has for its object the making of solenoids and spool-magnets in which greater extent of movement in the core is secured; and myinvention consists in the features and details of constructions hereinafter described and claimed.
In the drawings, Figure 1 is a side elevation,
' partly in section, of my improved solenoid and the spool than the other.
spool-magnet. Fig. 2 is a plan view of the armature for such magnet, and Fig. 3 a side elevation of the device applied to a watchmans clock. a
In making my improved solenoid and magnet I take a spool A, made of brass or other non-magnetic material, provided with a hole through the center and with flanges at the end, between which the wire is to be wound. I then wind the spools with wire, making the coils of sufiicient number to give the helix B the requisite size and thickness. Of course it will be understood that the wire forming the helices is ordinary magnet-wire. I then arrange an armature C in a proper base-piece D, made of insulated material. The armature is supported on a spring E and is arranged in an inclined position, as shown in Fig. 1. The spools A are fastened to the base-piece by screws or in any other suitable manner, so that the holes through their centers will be above the armature. As the armature is arranged in an inclined position one of its ends will approach much closer to the hole through I then make a core F of soft iron or other suitable magnetic material and preferably of a U shape, so that its two members will be of the proper distance apart to enter the holes in the spools A and be movable up and down in such holes.
The magnet may be used in any place desired, and in Fig. 3 I have shown it as connected to the printing-hammer of a watchmans clock, such as that described in the application above referred to; but I illustrate this use of the magnet merely for the purpose of explaining its action and not as a limitation. In this figure G is the case of the clock, the works being omitted as unnecessary to an understanding of my invention. In this case is journaled ashaft H, to which is attached the spring-arm 1' of a printing-hammer I, a spring J being attached to the case at one end and at the other to an armj on the shaft. The core F is connected, as shown,to the shaft by means of a rod K and crank-arm 70. L represents aportion of the register, against which the hammer strikes when thrown forward. In the drawings the parts are shown in their normal position, the spring .I holding the hammer back and the core raised. If now the magnet be magnetized by a current of electricity from any suitable source, the center of the core will be drawn toward the center of the helices, resulting in drawing the core downward and throwing the hammer forward to make a record. When the current ceases, the spring will retract the hammer and raise the core. In its normal position the core is out of the influence of the armature; but as it moves downward it comes within such influence and the armature becomes charged with electricity as the core moves down toward it, so that when the member of the core in the hole arranged nearest to the armature has reached the end of the hole the magnetism of the armature is such as to draw it farther down. As it moves down toward the armature, such member of the core will come into contact with it before the member in thehole farthest from the armature. The armature will therefore be forced back against the tension of the spring until both members of the core have come into contact with it, when the movement will cease. In this way the movement of the core is increased to the extent of the distance between the armature and the hole in the spool farthest from it, while at the same time its force is augmented continually to the end of its travel.
It will be observed that the armature and the coil act together to move the core in the same direction, and that inasmuch as the center of the core does not pass the center of the spool there is no tendency for the armature 2. A combined solenoid and spool-magnet and spool to work in contrary directions; but comprising the helices B B, the core F, the the armatnre,aeting with the spool, gives adarmature 0, attached to the spring E, and the ditional force to the blow of the hammer. base D, in which the armature is arranged I5 5 WVhatI regard as new, and desire to secure and to which the helices are attached, subby Letters Patent, is stantially as described.
