Louden Bird-Proof Barn Door Track and Hangers — Continued 



We believe this to be the neatest, strongest, easiest operated, and most serviceable barn door hanger 

 on the market. It has been in use on thousands of barns and we have heard nothmg but good words 

 spoken of it. You can make no mistake in choosing Bird-Proof. It will give you perfect service. 



The Track 



The track of the Bird-Proof Hanger is made from a solid 

 sheet of steel pressed into shape. The ends are closed by 

 special end stops, bolted in. The track is completely enclosed, 

 with the exception of the narrow slit at the bottom for the 

 hanger strap to work in. 



The lips of the track on each side of the slit are curved 

 downward and outward. This feature gives strength and stiff- 

 ness to the track and insures an even surface on which the 

 wheels run. 



The track is made in standard sections of 4, 6, and 8 

 feet long. When two or more sections are used, the ends 

 are held together by a steel splice. The splice is put on without 

 rivets or bolts and holds the sections firmly so they can never 

 spread apart. No other track on the market has this 

 feature. 



Support of the Track 



The track is supported by heavy steel brackets bent to fit 

 snugly around the track and close up to the lips on the under j j u 



side. A heavy corrugated rib in the center reinforces them strongly— they will never spread and the 

 track cannot sag under the weight of the heaviest doors. 



The brackets are hung to heavy, malleable iron wall fixtures which are bolted to the wall and support 

 the track in the proper position. The connection between the brackets and wall fixtures is flexible and 

 allows the track to swing freely out sidewise — one of two points of flexibility in this hanger. 



Fig. 961 shows how closely the brackets fit around the track, how the trolley wheel fits mto the groove 

 of the track and how the lips of this groove curve out. 



Flexibility of Track 



Fig. 918 shows the track hanging in normal position, but with the door swung partly out. This is the 

 flexibility for which there is the most common need. It saves many a break trom crowding stock and the 

 free swing prevents the door from sticking and binding in sliding past an uneven wall. 



The arrow points to the narrow space between the track and the barn siding which sometimes fills up 



with trash and dirt. With an enclosed track nailed or 

 fastened solid to the wall the dirt cannot readily be cleaned 

 out. and when wet will rust the track and rot the barn 

 siding. 



The Louden Flexible Bird-Proof Hanger is the only one 

 that perfectly overcomes this serious fault. 



By simply pressing outward on the door from the inside, 

 the track may be swung out to allow the trash and chaff to 

 drop out. This may be done instantly and easily without 

 gouging it out with a pitchfork or other tool. 



The Splice for Louden Bird-Proof Track 



In Fig. 893 is shown the splice clamp for holding the 

 ends of the track, together. No. 1 shows the splice clamp 

 standing on edge on top of the track and ready to be placed 

 in position.
