HARRY PENN AND LOFTUS LOWNDES, OF LONDON, ENGLAND.
ARMATURE FOR DYNAMOS AND ELECTRIC MOTORS.
SPECIFICATION forming part of Letters Patent No. 538,344, dated April 30, 1895.
Application filed August 13, 1894. Serial No. 520,216. (No model.)
To all whom it may concern/.-
Be it known that we, HARRY PENN, residing at 4.0 Harold Road,Upper Norwood, London, in the county of Surrey, and LOFTUS LOWNDES, residing at 25 Lordship Road, Stoke-Newington, London, in the county of Middlesex, England, subjects of the Queen of Great Britain and Ireland, have invented certain new and useful Improvements in Armatures for D yuamos and Electric Motors, (in respect whereof we have applied for, but not yet obtained, Letters Patent in Great Britain, No. 1,164, to bear date January 19, 1894,) of which the following is a specification.
This invention relates to an improved method of constructing armatures of dynamo electric machines and electric motors; in whichthe armature isbuilt up of thin sheetiron disks or rings, suitably separated from one another, each disk or ring being corrugated radially. These disks are pressed together by end plates, suitably shaped to fit the corrugations in the disks or rings; the end plates being keyed or otherwise secured to the shaft. In addition to the end plates, one or more plates, shaped to fit the corrugations in the plates, and keyed or feathered to the shaft, may be introduced at convenient intervals.
In order that our invention may be more fully understood, we have annexed to this specification, a sheet of drawings, to the letters of reference on which we now refer.
Figure I is an elevation of a ring armature, the top half being in section. Fig. II is an end view of Fig. I. Fig. III is a sectional elevation of a drum armature. Fig. IVis an end view of Fig. III. Fig. Vis aperspective view of an end plate. Fig. VI is a perspective View of a disk.
A and B are the end plates, keyed or otherwise secured to the shaft D. E is a screwed nut by means of which the sheet iron disks F are clamped between the end plates A and B. The flanges of these end plates are concentric with the shaft; being cast or otherwise fashioned with corrugations, or alternate projections and recesses, on their inner faces; the disks being similarly corrugated, by means of a press or other suitable appliance. When screwed together, the corrugations in the end plates coincide with the corrugations in the disks, keeping the disks concentric with the shaft, and preventing the one moving without the other.
In long arm atures, intermediate plates, corrugated on both faces (as C, Fig. III), sliding on feathers in the shaft, may be introduced at convenient intervals, to give extra support to the disks. The corrugations are preferably radial to the axis, and curved, as shown in the figures; but may also be made with straight instead of curved sides. In large armatures, the disks are made up of two or more segments; the number of corrugations varying with the size of plate.
Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we hereby state, that we do not limit ourselves to the precise combinations shown in the figures for the better illustration of the description given; but we declare that WVhat we do claim, and desire to secure by Letters Patent, is
In armatures of dynamos and electric inotors, corrugated sheet iron disks in combination with corrugated end plates, substantially as described and illustrated by the accompanying drawings.

HENRY CLARIDGE, J osEPH MARTIN BAKER.
