Fig. 2 Pels Coping Machine for Blocking Out Steel Beam* and Channels ■AT<- used in mistelJaneous bkxking-out work and, as shownin Fi^. 1, for cutting and channels in such a way thatthey will fit tfjgcther accurately in a car without subsequentmachining, sawing, or filing. Certain operations on chan-nels are troublesome since it is ncrcssary in an end sill, forexample, to cut away the flange and a considerable |K)rtion of the web of the channel in the center of the section whereit fits over the draft gear. The coping machine will performthis work on an end sill member in less than one minute,whereas, if the work is done with a cold saw, it will takefrom 20 to oO min. to accomplisli the same result. A single-end coping machine, designed for the above pur-poses and of the same general type as coping machines suc-cessfully used by prominent car companies for many years,is announced by Henry Pels & Co., New York. It is il-lustrated in Fig. 2 with certain parts of the toolin
