The first is called a lap, or multiple, winding and Fig. 55A shows a single coil of such a winding. This coil is made up of only one wire and both ends of the wire are each connected to a commutator segment. Such a winding is said to have only one conductor per shot. The distance from the first conductor to the second of the same coil is called the pitch of the coil or simply, coil pitch. Thus if the coil pitch were 8, then the first conductor of the coil would be in slot No. 1 and the second conductor would be at shot No. 8. Fig. 55-B shows a number of coils arranged on the armature core in proper order. In the figure while the coil pitch is shown as being 8, it is actually less so as not to complicate the drawing. Generators and motors usually have a number of conductors in each shot, as stated once before, the arrangement being as shown in Fig. 55-C and D. Wave Wound Armatures The second type of winding is known as the wave. This is illustrated in Fig. 56-A and B which show onlv one conductor in each coil. CO// " P/tc% Here too a number of conductors usually make up a single coil and Fig. 56-C and D show this in detail. The name series is sometimes also applied to this type of winding. . When asked whether this was not quite a big amount for the U. T. E. interest, Mr. Rosenberg admitted it was, but felt the investment well worth while, and Mr. Cherin concurred. The new officers of the Standard Slide Corporation, are now H. A. Rosenberg, president ; Nat Cherin, first vice-president and treasurer; Dave Harris, second vice-president, and Samuel Matloff, secretary. /. Perse Reports Business Favorable I. Perse of the Capitol Motion Picture Supply Company, New York City, reports that the supply business in the New York district is now operating on a more business-like basis than at any previous time during Mr. Perse's sixteen years of experience in this field. Mr. Perse further reports that the business of the Capitol Motion Picture Supply Company has enjoyed a steady increase during the last year and makes the prediction that this increase will be consistent throughout the rest of the year. As a pioneer in this field, Mr. Perse's predictions should carry considerable weight. Standard Slide Severs Connections with U. T. E. Through the purchase of the stock holdings of the U. T. E. in the Standard Slide Corp., 209 West 48th Street, New York, the largest slide manufacturers in the country, H. A. Rosenberg and Nat Cherin, who have been the active heads of this enterprising concern since its inception, now control practically the entire holdings, paying a sum of $22,500 for the U. T. E. interest. <(Rialto ' ' Under New Management C. F. McQuilkin, owner and manager of the Rialto Theatre, Enid, Okla., has recently purchased the Royal theatre from Rov Abernathy and C. Ticker. Mr. McQuilkin will redecorate the Royal and will install a large Photoplayer organ instead of using an orchestra. Seevral important improvements will take place at an early date.
