Track Brace 



Standard length of brace 2 feet. Brace is made of 5^ x I -inch steel. Clamp is of malle- 

 able iron. 



Where extremely long link track hangers are used to permit track to be 

 hung under beams or in suspending track from a very high ceiling, it is 

 sometimes necessary to brace the track at the ends to prevent the track 

 from swinging endwise and from creeping. Fig. 1209 shows two views of the 

 Clamp and Brace attached to a link track hanger. The brace can be placed 

 in any position, one end being clamped to the hanger and the other end 

 attached to any convenient timber or wall where it can be secured with a 

 lag screw or bolt. This brace is also used to prevent sidewise swinging 

 of the track.

Louden Track Openers are for use on sliding doors through which Litter and Feed Carriers pass. This 

 device automatically opens a way through the track so the door may be opened or closed without a 

 moment's delay. (See illustration Fig. 860.) A bar "T." having its ends downwardly inclined, slips 

 under and lifts the section "S" when the door is closed. When the door is open the section "S" drops 

 into place joining the two ends of the track, making the track continuous, ready for the earner to pass 

 over. (See illustration Fig. 859.) By having both ends of the bar "T" downwardly inclined it may 

 be set at either edge of the door and will open the track from either side. 



Special rigid hangers "H" and 

 "J" are required to hold the adjoin- 

 ing ends of the track "A" and "B" 

 in position so the section "S" v/ill 

 always drop into its place without 

 missing, and so the bar "T" will 

 always lift it instead of pushing it to 

 one side; also special straps "1, "bent 

 at an angle to fit the side of the barn 

 and the sides of the timber "E" and 

 hold it clear of the door hanger and 

 low enough to attach the hanger "H." 

 When the door is hung on the inside 

 of the barn, the section "S" is hinged 

 to the track "A" and the support 

 "C" is secured to the track "B." 

 This is a simple device, is easily fitted up and works perfectly. The outfit consists of the opener 

 "T" with brackets to attach to the door, hangers "H" and "J," the section "S" with its hinged con- 

 nection, the support "C" and the straps "I."
