CYLINDER FOR ROTARY ARMATUREs.
SPECIFICATION forming part of Letters Patent No. 276,024, dated April 17, 1883.
Application filed December 5, 18572.
To all whom it may concern Be it known that I, JAMES F. GILLILAND, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain 5 new and useful Improvements in Cylinders for Rotary Armatures, of which the following is a specification.
My said invention consists, first, in a cylinder for the rotary armatures of magneto-electric r generators, which is composed of parts adapted to be held together by the magnets without other fastenings; second, in such a cylinder the heads whereof are integral with the sides third, in a cylinder each half of which is pro- 1 ducedin complete form by casting diamagnetic material in a mold one portion of which is occupied by a magnetic pole-piece; and, fourth, in some details of construction, all as will be hereinafter described and claimed. Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a perspective view of a cylinder embodying my invention Fig. 2, an in- 2 side view of one-half thereof, the rotary armature being removed; Fig. 3, a longitudinal section through the complete cylinderon the dot ted line y y,- Fig. 4, a transverse section of the same on the dotted line cc; and Fig. 5, atrans- 3o verse section of the mold in which the halves are cast, one of said halves beingshown there- 1n.
In said drawings, the portions marked A represent the cast cylinder portions; B, the 3 5 pole-pieces; O, the revolving armature, D,
bushings for the bearings for the armaturejournals, and E the mold.
Each of the castings is molded to form, in connection with the pole-piece, a full hall of the cylinder, including one-half of each head, and two of these halves, when laid together, form a complete cylinder. The process of producing these halves or sections is as follows Amold is, prepared the cavity in which is of 4 5 the form of the completed section. (See Fig. 5 for cross-section.)- The pole-piece B, having been previously prepared,is laid in the portion of the cavity formed to receive it, and molten (No model.)
metal is then poured in, which fills the remaining space and forms the castingA. The mold 0 is formed with a rib at each end, which leaves the groove a in the casting, which prevents endwise movement of the bushings D. The preferable material for the pole-pieces is castiron, as is usual, and for the casting A whitemetal; but I do not limit myself to materials, except so far as is necessary to make the invention operative, as my presentinvention relates only to the construction of the cylinders. It will be understood, of course, that the cylin- 6o ders may be divided into more parts than two without departing from my invention. It will also be understood that the sides may be left partly open between the pole-pieces, as a solidsided cylinder is not necessary to the operation of a rotary armature so long as the polepieces are properly arranged.
The armature O is or maybe of any ordinary or approved form suitable for use in a device of this character.
The bushings l) are preferably of brass, and are each formed in a single piece, as shown. They are placed on the armature-journals by being slipped over the ends, and serve the usual purposes of journal-box linings. Being 7 \v hole, they serve the further purpose ofholding the halves of the cylinderin proper relation, as they enter partly into both. They are preferably provided with ribs, which fit into the grooves a and aid in the above object, besides 8o preventing any endwise movement either of the bushings themselves or of the armature.
The cylinder produced in this manner needs no fitting whatever, but is ready for use as soon as cast. the magnets, and thus all fastening devices are entirely dispensed with. Being cast in a solid metal mold, every cylinderhalt' is exactly like every other, and any two halves can therefore be placed together indiscriminately, and, go all parts being interchangeable, any worn-out -or broken part can be at any time replaced without diit'L culty.
Having thus fully described my said invention, what I claim as new, and desire to secure 5 by Letters Patent, is-- The halves are held together by 8 3 1. Acylinderforrotary arnintures,coinposed ofpnrts, each part being a longitudinal secticn of the cylinder, and having a correspond ing portion of the cylinder-heads castintegral therewith, substantially as set forth.
2, Acylinderforrotmy arinatures, composed of castings A, having pole-pieces B incorporated therewith, said castings A including the ends or heads as well as the sides of the cylinder, substantially as set forth.
3. In ncylinder for rotary armatnres, which, including the heads, is divided longitudinally into parts, the combination, with said parts, of bushings Dior the armnturejournals, which serve also to hold the parts in proper relation, substantially as set forth.
4. The combination of the cylinder parts A, pole-pieces B, armature O, and bushings D, said bushings being provided with ribs which fit into grooves in the head portions of said cylinder parts, substantially as described, and for the purposes specified.
In witness whereof I have hereunto set my hand and seal, at Indianapolis, lndizina, this 1st day of December, A. D. 1882.
