The Louden Spring Balance Galvanized Manger is the most convenient as well as the strongest and most 

 durable manger of the kind manufactured. The upper part which is made of heavy galvanized sheet steel 

 is made to fit a concrete bottom, as shown in the cut. The divisions which convert the manger into com- 

 partments, or individual mangers, are reinforced by Spot Welded T-iron all around the edges. 

 The back or front (whichever it may be called) is attached to the divisions by angle irons bolted thereto. 

 The back (or front) is left off in shipping and the entire manger is packed flat to take a low rate of 

 freight. In putting the manger together no punching or drilling of holes or riveting is required. 



The manger is generally built in sections of 4 to 5 compartments and is further strengthened by a brace 

 rod, running the entire length of the section, the brace rod being clamped on the upper edges of the divisions 

 by malleable iron clamps. The brace rod also serves as a guard to hold the hay in the manger. The manger 

 is hinged to the stall post by malleable hinge castings adjustably secured to the inner ends of the divisions. 

 Pivots adjustably secured to the stall posts are used to hold the hinges in place and permit the raising and 

 lowering of the manger. By this means it is readily adjusted up or down, or in or out, to make it fit the 

 concrete bottom. With stalls having central posts, pivot clamps are used instead of the pivot pins required 

 by our double-post stalls. 



To assist in raising the manger and to hold it in elevated position for cleaning, heavy Special Coil 

 Wire Springs are used, as shown by the cuts. Two different sizes of springs are used for lighter and heavier 

 mangers, which are made of the best spring steel wire that can be procured. Many experiments were made 

 and scores of sample springs from all the leading spring manufacturers in the country were tested before we 

 decided upon the springs to use. As a result we have a Spring Balance Manger which cannot be equaled. 

 Each spring has a working strength of from 400 to 600 pounds, according to size and adjustment, and after 

 the mangers are raised one-half way up, they will be held by the springs in a perfect balance at any point 

 and without any additional assistance whatever. 



The attachment of the spring is such that when the mangers are down in feeding position the springs 

 will help to hold them more securely in lowered position and to keep the cow from nosing them out of place. 

 The upper ends of the springs are usually connected to the stall partitions by clamping holders similar to 

 our standard stanchion holders which may be readily and easily adjusted back or forth thereon to increase 

 or diminish the tension of the springs. With the two sizes of springs and the complete and convenient 

 adjustments, any size or weight of manger may be balanced to perfection. 



The mangers when raised stand 8 to 10 inches higher than any others in the market and there is 

 ample room for the heads of the cows when the manger is raised. They are so rigid that a section of four 

 to six can be raised or lowered at one end — something that cannot be done with any other manger with- 

 out twisting it all out of shape. We do not know of any point that can be imagined but what has been taken 

 care of in our Spring Balance Mangers.
