There is nothing about it that will give, spread, loosen or get out of order; it is trouble 

 proof — and will stand up under long years of heavy service. 



No bolts or nuts are required for putting track and hangers together. The hangers 

 "button" to the track and the nailmg plates "button" to the hanger, the plates being nailed 

 to the joists. If the barn is ceiled, ceiling plates with large screws are used instead of 

 nailing plates. 1 he few simple instructions sent with each order, enable any one to get a 

 first-class job, with the track perfectly levelled. 



James I-Beam track saves the cost of special curves. The track may be quickly and 

 easily bent to any curve while it is being put up in the barn — heat is not required to do 

 the bending. As several curves are often necessary in a barn, and as these curves cost 

 several dollars apiece when ordinary flange track is purchased, this saving is no small item; 

 and is a very big one if the track is for a round barn. 



Many litter carriers use a track that is not at all adapted to the litter carrier. A track 

 that is flat has but little strength vertically. 



When used outside the barn, snow and sleet accumulate on the flat surface, blocking 

 the carrier wheels. Before the carrier can be used outside, the snow or ice must be cleared 

 from the track by melting or scraping it off — and this is no easy task, for the track is up 

 high. Inside the barn, a flat track allows the dirt to accumulate. 



The James Track is different. Its narrow tread affords no place for snow or sleet or 

 dirt to collect — no sleet storm will put it out of use just when you need it most, in the 

 disagreeable weather. 



The narrow tread of the James track offers little resistance to the travellers; there 

 being little friction surface, the carrier runs easily. 



Track being one piece cannot spread and bind the tracker wheels. 



Tlie depth of the track and its heavy flanges at top and bottom make the James 

 track stiff — it does not spring under heavy loads. This in part accounts for the ease 

 wath which big loads are handled on the James track. Any track without the necessary 

 vertical strength will spring, making "low spots" in between hangers; and the carrier 

 will push hard and jerkily. 



The depth of the James track gives it long life because of the greater thickness of 

 wearing surface ; when the upper bead has worn thin, if it ever does, track can be turned 

 edge for edge, the bottom bead forming new running surface. It will be giving satis- 

 factory service many years after ordinary flat track has gone to the junk pile. 



In fact, James track meets every condition required of a litter carrier equipment in 

 any barn ; it may be hung high or low, and run wherever there is room for the tub to pass. 



The shape of the track is something like that of a railroad rail and for just the same 

 reason. When the first railroad was constructed, a flat track was used, and soon aban- 

 doned for the present shape, in order to secure greater strength, longer wear and an even 

 running surface. 



It is heavy at the points of greatest strain. The weight on top puts the compression 

 strain where the track is heavy; and the pulling strain where the track is just as strong. 

 The compression strain and the pulling strain neutralize each other at the center of the 

 track — less strength is required there, and hence that part of the track is made lighter. 

 Every particle of metal helps to support the load, and the James track is therefore many 

 times stronger than other types of^ track of equal weight. 



Made of high carbon steel, same as a railroad rail; two inches deep; is easily put 

 together with the channel steel splice bars and /^y-in. bolts — the track will not come apart 

 and the joints will not give or sag. Holes in the track are two inches apart on centers.
