Louden Adjustable Center-Pivot Gate Hinges 



Fig. 1172 Fig. 1173 Pat'd Jan. 18. 1916. Fig. 1174 



The above are views showing three different ways of using the Louden Adjustable Center-Pivot Gate 

 Hinge. Fig. 1172 shows the use of the hinge with \^i or Ijs O. D. tubing. Fig. 1173 shows the hinge 

 attached to a large post or column, and Fig. 1 1 74 shows a double hinge attached to a large post or column 

 to hang a gate on each side of the column. For 1^8 or I Ja O.D. tubing, four pieces of malleable castings 

 are used which are rigidly clamped to the tubing by six heavy bolts. 



The hinges can be clamped to the posts at different angles as shown by Figs. 1 1 75 and I 1 76, to vary 

 the distance between the gate frame and the post to which it is hinged, to suit requirements. This is an 

 important feature. If the space between the gate posts should happen to be a little too wide or too narrow 

 an adjustment of 2} 2 inches can be made in setting the hinges, so the latch on the gate and the catch on 

 the post will always be correctly adjusted.

These figures are sectional views showing the adjustment of the hinges. Fig. 1175 shows the hinge 

 extended or widened and Fig. 1 1 76 shows it contracted or narrowed. Fig. 1 1 77 shows the attachment to 

 a large post by means of clip bolts which can also be adjusted as explained. (See Plate 16, page 138.) 

 When a gate is hinged on each side of a large post, as shown by Fig. 1 1 74, the hinge castings for the large 

 post is bolted together as shown, and by using longer bolts on one side and shorter bolts on the other side, 

 the castings may be adjusted on the post. The center pivot permits these adjustments and also offsets 

 the hinge so the gate can be opened clear back against the panel of the pen which is another important 



feature not possessed by other kinds of hinges. Of all other gate hinges for 

 M|g tubular posts or columns, none are so strong or so convenient in use, or 



MH Bl^ have the desirable adjusting features of the Louden Hinge.

Louden Safety Gate Latches 



Fig 1178 is a detailed view of the Louden One-Way Safety Gate Latch used on our animal pens. It 

 is provided with a Latch Guard which swings out over the latch as soon as it drops into the catch and 

 prevents it from being lifted out of the catch until the keeper is pushed back out of the way. No animal 

 can open the latch when it has this Latch Guard. Fig. 1 1 79 is a detailed view of our Two-Way Safety 

 Latch for alley gates which swing in both directions. The Latch Guard is pivoted above the notch and will 

 swing to one side or the other enough to allow the latch to slide up the catch from either side and drop 

 into the notch, but not enough to permit it to pass clear through. To unlatch the gate in either direction the 

 keeper is pushed to the other side. Fig. I 1 80 is a Two-Way Safety Catch for a square wooden post or a wall.
