CHARLES H. ATKINS, OF BOSTON, MASSACHUSETTS.
ELECTRICAL APPARATUS FOR SEPARATING METALLIC PARTICLES FROM PAPERPULP.
SPECIFICATION forming part of Letters Patent No. 360,842, dated/April 12, 1887. Application filed December 11, i886. Serial No. 221.248. (No model.)
To all whom it 71mg/ concern.-
Be it known that I, CHARLES H. ATKrNs, of Boston, Massachusetts, have invented a new and useful Apparatus for Separating Metallic Particles from Paper-Pulp, of which the following description and claims constitute the specication, and which is illustrated by the accompanying sheet of drawings.
This invention is for the purpose of separating particles of iron or other paramagnetic metals from paper-pulp; and it consists of annular 'electro-magnets, which form part of a tube through which the pulp passes on the way from the stuff-chest to the machine. -f'
`Figure 1 is an exterior view of the apparatus, but broken at the middle to show an irregular cross section thereof. Fig. 2 is a longitudinal diamctric section of what is shown in Fig. l.
A is a coil of insulated wire,wound upon the tube B, which tube is brass or other diamagnetic metal, as also are the collars C and D,
' which are fixedto the ends of the tube B. The
' chest and toward the machine, respectively.
A series of short tubes, I, are placed within the tube B,and are separated from each other and from the tubes E and F by a series of rings, J. The tubes I are of iron or other paramagnetic metal, While the rings J are of brass or other diamagnetic metal, and are shorter in axial length and larger in interior diameter than the tubes I. The coil A forms a part of an electric circuit, worked by a battery or other generator. (Not shown in the drawings.) When a currentof electricity is passing through the coil A, and a current of paper-pulp isA passing through the interior of the apparatus, the tubes I are separate electro-magnets, and operate to draw to themselves whatever particles of 'iron or other paramagnetie metal may be mingled in the mass of pulp whichis passing through them. These particles adhere to the tubes I, and, as far as they are dislocated by the passing pulp, are forced into the annular spaces within the rings J, and are kept in those spaces by the strong magnetism of the ends of the tubes I, which ends constitute the poles of those tubes, respectively.
Wheneverit becomes necessary or convenient to do so, the electric current may be broken and the apparatus removed from the tubes between which it is interposed,when the accumulated metallic particles will fall away from thev tubes I, and may readily be removed from the interior of the apparatus; or the apparatus may be cleaned out at proper intervals by merely breaking the electric current and directing a stream of Water through the conduit of which the apparatus forms a part.
This invention may also be used for separating metallic particles from oil, grain, or other liquid or granular substances.
I claim as my invention- 1. A tubular electro-magnet consisting of .the coil A and a paramagnetic tube within that coil, and of mechanism, substantially as described, for coupling that tube to other tubes extending from the respective ends thereof, all
