HENRY GEISENHONER, OF SCIIENECTADY, Nlillv YORK, ASSIGNOR TO TIIE UNITED STATES PATENT OFFICE,
GENERAL ELECTRIC COMPANY, OF NEIV YORK.
BINDING-BAND FOR' ARMATURES.
SPEOIFICATION forming part of Letters Patent No. 583,991, dated June 8, 1897.
Application filed October 31, 1896. Serial No. 610,651. (No model.)
To aZZ wwm, it' masy conccrn:
Be it known that I, HENRY GnIsENHNER, a citizen of the United States, residing at Schenectady, in the county of Sehenectady, State of New York, have invented certain new and useful Improvements in Binding- Bands for Armatures, (Case No. 481,) of which the following is a specification.
In the construction of armaturcs it is necessary to provide binding-bands to secure the conductors against centrifugal action when revolving at high rates of speed. These bands are usually made of steel or Germansilver Wire, the number of turns in each band depending upon the number of bands to be employed and the rate of speed at which the armature is to revolve. A construction of this kind is very suitable for small armatures and would be for large ones, except that it is necessary at times to remove the bands for repairin g the armature. The wires formiu g the bands, being soldered together at intervals, have to be cut to remove them, destroying the band. In small armatures the cost of new bands is not very great, but as the size increases it becomes prohibitive.
The present invent-ion has for one of its objects to provide a bindiug band which can readily be'removed from the armature without destroying it and one having` great slreugth and simplicity of construction.
The invention further has for its object to provide a removable binding-band for armatures which shall exert a practically equal binding effect over all portions of the core.
The invention also has for its object to provide elam ping devices which shall be thin radially with respect to the armature and smooth in contour.
In the accom panyin g drawings, attached to and made a part of this specification, Figure 1 is a partial end view of an armature. Fig. 2 is a partial plan view of a band. Fig. 3 is a perspective view of a clamp. Fig. a is a perspective view of a wedge, and Fig. 5 an end view of an armature.
The armature A is made of laminated iron provided with slots in which are placed the conductors B. The band Cis provided with loops D D', formed by bending back the ends of the band and securing them by rivets E. In addition to the rivets, solder may be employed for increasing` the strength of the joint. In the enlarged end of each loop is plac-ed a wedge F, having a rounded outer surface which engages with the band C, a'nd inclined surfaces F', engagcd by similar surfaces ou the elamps G G'. The wedge F is secured to the band C by solder and rivets a.
The loops D D' are cut away slightly, so that when the elamps G G' are assembled the band will be substantially the same width throughout.
The elamps G G/ are provided with projections g g', having inclined surfaces (/2 engaging with similar surfaces F' on the wcdge F. The back portion of the clamp is curved outwardly at Q3 for additional strength. At H, I show suitable insulation placed between the armature-conduetors B and the band C.
In assembling, the armature A 'is wound in any desired manner, after which the bands C, having previously been provided with loops D D' and wedges F, are placed in position and the elamps G G/ drawn together by means of the bolts I I'. The inclined surfaces of the clamps, engaging with similar surfaces on the wedges, will, when the elamps are drawn together by the bolts I I', draw the ends of the band C together, securing the armature-conductors against movement independent of the armature-core. By this construction I am enabled to provide a simple binding-band which can be readily removed or replaced, and by arrauging the surfaces F' and (/2 as shown the drawiug together of the ends is accomplished at a point very nearly in line with the portions of the band lying next the armature-core.
On account of the dil'liculty experienced iu elamping the bands around the armature with an'even teusion and without disturbing the insulation it is desirable to divide the band into a number of Sections, as shown in Fig. 5, the number of such sections being depcndent upon the size of the armature. In the present instance three Sections are shown, and by tightening the several sets of elamps G G' the band is made to compress the armature with an even tension throughout.
Ioo
It is preferable to make the elamps G and loops D D' with as smooth a Contour' as possible, to prevent foreign articles from being eang'ht thereby and revolved With the armature.
Ihat I elaim as new, and desire to secure by Letters Patent of the United States, is-
1. In a binding-band for armatures, the Combination of a metal strip, loops formed at the extremities of the strip loybending` the ends baekvv'ard and seenring` them to the strip, a Wedge seenred to the strip, and elamps engaging with the Wedges for drawing' the extremities of the band together.
2. In a binding-band for armatures, the combination of a metal strip, Wedges seenred to the extremities of the strip, elamps provided With inelined snrfaees eng'aging With similar surfaees on the wedges, and means for seenring` the clamps together.
In a binding-band for armatnres, the combination of a plurality of metal strips, each provided with means for seen ring it at its extremities, and wedges and bolts foi` seenring` the metal strips.
et. In a binding-band for armatures, the combination of a metal strip provided at its extremities with Wedges, elamps provided With projeetions having` inelined surfaees engaging with the wedges, the projeetions on l I Eil itY EISEN l [N ER.
