UNITED STATES PATENT OFFICE.
ASA FRED BATOHELDER, OF SCI'IENEOTADY, NEV YORK, ASSIGNOR TO THE GENERAL ELECTRIC COMPANY, OF NEV YORK.
SPACE-BLOCK FOR ARMATURE-CORES.
SPECIFICATION forming part of Letters Patent No. 595,364, dated December 14, 1897.
Application led September l5, 1897. Serial No. 651,731. (No model.)
To all whom it may concern:
Beit known that l, ASA FEED BATCHELDEE, a citizen of the United States, residing at Schenectady, in the county of Schenectady, State of NewYork, have invented certain new and useful Improvements in Space-Blocks, (Oase No. 619,) of which the following is a specification.
This invention relates to spaceblocks of ro dynamo-electric machines in which the armature-core is built up in the usual manner with annular iron laminae in layers suitably supported upon an internal support or spider adapted for the purpose.
The invention has for its object to provide a light, strong, stiff, and durable space-block constructed and arranged as hereinafter set forth and claimed. 4
In the accompanying drawings, Figure l is a view in perspective, showing portions of three space-blocks, that at the left being a portion of a space-block constructed in accordance with this invention and those at the right being modifications. Fig. 2 is a detailed plan View showing a space-block located between two bundles of laminze, and Fig. 3 is a detail View of the outer edge of a lamina adapted for'this invention.
In carrying out this invention the spaceblock is constructed with an internal support or spider l, having its arms 2 provided with a circumferential flat strip of metal or ring 3, mounted on and secured thereto in any suitable manner. Mounted on and secured to the strip or ring 3 are radial arms or branches et, consisting of thin strips of metal, as' shown at the left of Fig. l.
A space-block constructed as hereinbefore set forth is located between two bundles of lamins.
If desired, in order to prevent the thin radial strips or arms on the periphery of the strip or ring 3 from being bent and displaced, the radial strips may be secured in any suitable manner to the adjacent laminas of the two bundles of laminze between which the space-block is located. This may be accomplised, for example, by one of the modifications shown at the right of Fig. l, in which 5o the radial arms 5 consist ofl thin strips of metal formed with lateral projections 6 adjacent to their outer ends, which engage slots 7 in the arms S of the laminre 9 adjacent to the space-block located between two bundles of laminas l0, as shown in Fig. 2. By means of this construction the radial strips or arms 5 are held rigidly in place and kept from bending. In either form of the invention a light, strong, and durable construction is provided. In the other modification at the right of Fig. l the space-block is provided with arms ll, consisting of thin strips of metal formed with a single lateral projection l2 adjacent to their outerends. In this case the outer ends of the arms 1l engage but one lamina 10 by means of projections l2 engaging slots '7.
This invention is shown as employed in a toothed armature, the arms S of the laminze 9 forming the projecting armature-teeth. The radial arms of the space-block correspond in number to and are in alinement with the projecting armature-teeth. By this means ven tilating-spaces are afforded.
I clainrl. A space-block for armature-cores, consisting of an internal support or spider, a circumferential ring mounted on the arms of the spider, and radial arms consisting of thin strips of metal mounted on said circu1nferential ring, as set forth.
2. A space-block for armature-cores, consisting of an internal support or spider, a circumferential ring mounted on the arms of the spider, and radial arms consisting of thin strips of metal mounted on said circumferential ring and having lateral projections adjacent to their outer ends, as set forth.
3. In an armatureecore, the combination with sections of built-up laminze, of a spaccblocl: consisting of an internal support or spider, a circumferential ring mounted on the arms of the spider, andradial arms consisting of thin strips of metal mounted on said circumferential ring, the space-block being located between two sections of built-up laminze, and the radial arms being secured at their outer ends to the said sections.
4:. In an armature-core, the combination with sections of built-up laminae, of a spaceblock located between two sections of builtup lamin, the laminze adjacent to the spaceblock being provided with slots, and the IOO space-block consisting of an internal support or spider7 a circumferential ring,` mounted on the arms of the spider, and radial arms consisting of thin strips of metal mounted on the circumferential ring` and having lateral projections adjacent to their outer ends, eu-
gaging the slots in the laminze adjacent to the l space-block, as set forth.
5. A space-block for armature-cores, consisting` of an internal support or spider, a at ring` mounted on the arms of the spider, and radial arms consisting` of thin metallic strips mounted on the lat ring', as set forth.
6. In an armaturecore7 the combination with sections of huilt-11 p laminae having radial arms forming a toothed structure, of a spaceblock consisting of an internal support or spider, a circumferential ring` mounted on the arms of the spider, and radial arms consistf ing of thin strips of metal mounted on said circumferential ring, the space-block being located between two sections of built-up laminze, and its radial arms corresponding` in number to and in alinement with the radial arms of the built-up laminze, as set forth.
7. ln an armature-core, the combination with sections of built-up laminze having radial arms forming a toothed structure, of a spaccblock` consisting of an internal support or spider, a circumferential ring; mounted on the
