By means of the Louden Hay Rack 

 Fig. 645 Clamps and Plates the timbers of the rack Fig. 646 



can be put together and securely held in position without having to bore holes in the sills or upper 

 cross pieces. The rack can be built in one-half the time where the clamps are used and timbers are not 

 weakened by having holes bored in them. 



In illustration. Fig. 647, is shown a hay rack under course of construction, the main and cross sills 

 having been clamped together. The washers are placed at the points "W", the intermediate plates at 

 "P", and the clip plates at "C". There is no easier way or better place to build a hay rack than on the 

 running gears of a wagon. No measuring will be necessary and the rack will always fit the bolsters. 



Lengthen out reach until weight of the load will be evenly divided between front and rear axles; stand 

 main sills on edge close up to standards; place cross sills in position and clamp the two together as shown 

 in Figs. 646 and 647. The upper cross pieces should be set about two inches back from the ends of main 

 sills in order that the intermediate plates may get a good, firm hold on the timbers. In this way any one 

 can build a good rack in a short time, the only tools necessary being wrench and hammer. The rack will 

 be about one-third stronger than if built in the old way, as the sills will not be weakened by holes, and 

 the time saved will more than pay for the clamps. 



The Intermediate Plates 

 are of malleable iron and 

 have heavy flanged edges 

 or shoulders to fit over the 

 edges of the main sills "S", 

 and cross pieces " D ", hold- 

 ng them firmly in position. 

 These plates also have lugs 

 or projections (two above 

 and two below), that are 

 driven into the timbers 

 when the clamps are drawn 

 down tight, thus prevent- 

 ing all rubbing or chafing 

 and making it impossible for 

 the sills or cross pieces to 

 warp and get out of line. 



The Top Washers are 

 also of malleable iron and 

 have a good, wide bearing 

 surface to prevent them 

 from cutting into the wood. 

 The steel bottom plates are 

 extra heavy and not only 

 act as washers but prevent 

 the bottom cross pieces from 

 being split by a severe 

 strain. 



Material Necessary for Sixteen-Foot Rack 



Two pieces 2x8. 16 ft. long for main sills. 



One piece 2x4. 16 ft long to be cut up for bottom pieces 



Four pieces 2x4, 7 ft. long for cross bars. 



Two pieces 2x4. 6 ft. long for front ladder. 



Four pieces 2x6. 6 ft. long for sides of rear wheel covering. 



Four boards 1x8, 16 ft. long for lengthwise pieces on sides. 



One board I x6, 1 2 ft. long for tops of wheel coverings. 



Two boards 1x12, 16 ft. long for bottom of rack. 



The above specifications cover material necessary for rack 7x16 feet to be used with 



our 14-inch clamps: but if it is desired to make a rack of different length or width the 



dimensions of the lumber must be changed accordingly. To build a rack with^ larger 



main or cross sills use the 1 6 or 18 inch clamps.
