IMPROVEMENT IN ELECTED-MAGNETIC MACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
. I, A. E. DUPAS, of the city of Paris, France, but
now residing in the city of New Orleans, State of Louisiana, have invented certain improvements on my electro-magnetic machine, for which Letters Patent of the United States were granted me on'the 17th day of August, 1869, which I call a Duplex Armature Vibrating Electro-Magnetic Engine, of which the following is a specification.
Nature and Objects of the Invention.
The first part of my invention onimprgvement relates to a combination of a multipolar magnet, which can be extended indefinitely, so as to embrace any number of poles, according to the power required to be brought into development, in such a manner that both extremities of the same are always in magnetic equilibrium, with the object of preventing unnecessary wear of the central pivots, or articulating joints, on or at which the frame supporting the armatures vibrates.
The second partof myinvention relates to the combiuation of a double-vibrating exactly-balanced frame, with rectangular partially-hollow armatures, connected with and supported at the two vibrating extremities of the same, with the objectof acquiring the greatest possible magnetic momentum, and hence the produc-v tion of any given power with the least possible amount and weight of metal.
The third part of my invention relates to a peculiar mode of making the magnetizing-coils employed in my engine, in order to pass the current of electricityaround the electro1nagr1et,at right angles to the axis of the latter, and always in the same direction, whatever the number of coils required or used in the engine.
As in the case of my eleotro-magnetic machine, patented as aforesaid, on the 17th day of August, 1869,
my present improvement is especially-designed as a motor for operating sewing-machines, or the like, in
which no great measure of power is requisite to the eiiicient working of the same.
Description of the Accompanying Drawings. Figure l is a bottom view of a' platform or table, on
which a sewing-machine is fixed, with my engine at tached thereto;
,Figure 2, a side elevation;
Figure 3, an end view of the same table, &c., with the rear-side supporting-legs withdrawn or removed; and
Figure 4, a detached view of a section of a magnetizing-c'oil, as constructedby me, for use in connection with my engine.
table, B, to'which'they are firmly fastened, by which the multipolar electro-maguet O G O", the partiallyhollow armatures D D,, and the vibrating frame E are secured, and supported in the position shown in the drawings. i I
The multipolar magnet O G. O" is supported by the axis F, of the vibrating frame'E, which passes through its poles, and thus constitutes the base or culasse v of the magnet, in the operation of the. machine. The
culasse of the magnet, in otherwords, constitutes the axis on which the frame E vibrates.
The armatures D D are slightly concave, on the,
contact between the armatures and the poles of the magnet, and hence there can be neither friction nor wear of the parts.
On the three other sides, the armatures'D D have perfectly straight lines and plane surfaces, and hence,
I call 'them rectangular, although, in very strictness'of.
language, they are not so. They are made partially hollow by the recesses or hollow spaces H.H, and are, therefore, of exceeding lightness, as compared to what they would be if solid, while yet possessing the same power they would then have.
M It may be, that under some circumstances, I'mig-ht wish to combine the hollow cylindrical armature, employed in my patented machine, with my herein-described engine, and I wish to reserve the right to do so, if I shall consider it advisable. Theoperat-ion of closing and breaking the circuit in my present improvement, is accomplished by a modification of the same means-described in the specification annexed to my patent of August 17, 1869, and in substantially the same way, so as to allow the armatures and their supporting-ii'ameto complete such stroke by their momentum. -Nor is there any sufficient difi'erence between my manner of connecting this improvement with a sewing-machine, or the like, and thatdescribed in my said patent, to require a special description herein. It is enough to say, I shall hold myself at liberty to use any suiiicient means for this purpose, andalso any mode of applying the same.
So, also, to start and stop the machine, and to regulate its spced,'I reserve the right of using the same means described in said patent, or any others that are the equivalents thereof.
Fig. 4 illustrates my mode of making my magnetizing-coils. I use fiat wire or thin strips of metal 'in. making them, which I wrap in a perfectly straight line, until I get as many folds or convolutions as I desire, as, for example, as shown at 1', and then fold over the strip of metal at right angles to the line of the coil just completed, as shown at 2, and then against rightam gles, as shown at 3, so asto make the direction of the wrapping in the second coil the same as in the first, and, as in that case, in such manner that each suo ccedin g thickness or fold of wrapping shall be precisely over the preceding ones, as shown at 4, and so on nntil the coils are completed.
I am aware that flat wireha-s been used in making coils for magnets, and 1 do not, therefore, claim the use of'the same for such purpose. My invention consists of the peculiar mode of making magnetizing-coils, which I have just described, and nothing beyond this do I pretend to consider 'my own.
The advantage resulting from my mode of constrnc tion, in addition to what I have already pointed out, is very great. There is far less resistance to the current of electricity than in spirally-wrapped coils, and, in consequence of the layers being brought as near as possible to the cores, a great diminution of the danger of consuming the zinc used, which is now generally soon wasted from this cause, as Well as less liability of crystallizing the copper, which, of course, puts it out of service, by a continued use of the engine for any length of time.
1 claim, as my invention 1. The multipolar electro-magnet O G 0, when constrnctedand applied as described, in connection with thedouble-vibrating frame E, for the purpose set forth.
