SPLICED SILLS IN LONG PASSENGER CARS. The splicing of sills of long passenger cars has been prac-ticed for a number of years with apparently no unfavorableresults. The subject was introduced by Mr. H. M. Pfleger,Mechanical Superintendent of the Pullman Company, at the. Spliced Passenger Car Sdls. recent M. Q. B. convention in a topical discussion entitled:Are there any objections to splicing all sills of long passengerequipment? If not. how should this be done according to thebest modern practice? As a result of the discussion the ques-tion will be presented at the convention nextyear with recommendation. Mr. Pflegerscomments on the practice were as follows: The practice followed by a large numbernf car builders is to make one splice in thesills of cars 50 ft. and over in length, andthis may be taken as a strong indication thatthere are no objections to splicing sills inlong passenger cars; and it may be safelysaid that if a sill of a passenger car has onesplice in it, properly made, it is as strong asa continuous sill. Practice has demonstratedthat a properly spliced sill will last as longas a continuous sill, and can be safely usedfor both side sills and draft sills. The prac-tice of the Pullman Company f
