SPECIFICATION forming part of Letters Patent No. 631,786, dated August 29, 1899.
Application filed December 15, 1898. Serial No, 699,344. (No model.)
To all whom it may concern: from the line 3 3 of Fig. 1. Fig. 4- is a per Be it known that I, HENRY GEISENHONER, spective of one of the separators. Figs. 5 a citizen of the United States, residing at and 6 are modifications. Schenectady, in the county of Schenectady, In 1, A is one of the laminations of 5 State of New York, have invented certain new the armature, having the teeth B B. To this 5 5 and useful Improvements in Space-Blocks, are attached the separators C, each of which (Case No. 983,) of which the following is a consists of a strip of soft iron, such as is specification. shown in Fig. 4. It is provided with loops My present invention relates to the venti- C C punched out from the iron of the strip, to lating space-blocks now used in the armaand in this case shown as on opposite sides 60 tures of all dynamo-electric machines, and thereof. OtherloopsA are punched out from has for its object to provide a cheap conthe iron of the lamination A. The parts are struction by which they may be readily made assembled by passing the loop C through one from magnetic material with considerable of the loops A'and the loop C through the saving in cost and the consequent advantage other one upon the opposite side of the strip 65 derived from the use of iron. In general C. The loops A are then punched into the these devices have heretofore been made from holes in the loops C C securely binding the cast-brass and have been riveted to one of parts together. the armature laminations, the usual course In the modified form shown in Fig. 5 the being to build up a certain section of the arloops C C are cut from a strip the width of 70 mature of the iron plates and then insert which is shown in dotted lines, and then they one of the armature laminae having the spaceare bent in opposite directions, so as to sup blocks attached, and so on until a sufficient port the strip C firmly. core has been built. \Yhile this is eflicient In the further modification shown in Fig. and useful, it is desirable that all of the ma- 6 both of the loops C C are upon the same 75 terial in the core of the armature should be side of the strip C. In this case of course of iron so far as it is possible. Other forms the clips or loops A in the laminations should of ventilating devices have been devised in be so disposed as to preserve the alineinent which projections upon one of the armature of the strip with the teeth B B; but this is 0 laminations have been formed to hold the manifest to a skilled mechanic. 8o other-laminae apart, but the material of Which Other modifications of the invention may these laminations are formed is quite thin, be easily devised, which I have not deemed and this device has not proved eifective. it necessary to illustrate or describe. The 3y my invention I apply to the lamination preferred form is that illustrated in Fig. 1, ribs or separatorsof iron, which are held in and I have found this to be cheap and efii- 85 place by clips punched out from the armacient. ture lamination, the ofiice of which is only to What I claim as new, and desire to secure retain the ribs or separators in place.
