696 Rcjwrt on the Trials of Imjylemcnts at Bedford. 



The workmanship and materials arc good, although the waggon is somewhat 

 costly, the price being 44?. 



No. 5036. F. P. Milford. — The peculiarities of this waggon are that the 

 middle hind carriage-pole is done away with, which arrangement cannot add 

 to its strength. The front wheels also have 12 spokes and the hind wheels 

 14 spokes each, as compared with 10 and 12 in the other waggons. The 

 degrees of inclination are also small, being 2i° and 3°. The load is well 

 placed, for more than three-quarters of it rests on the larger hind wheels. It 

 was principally commended on account of its draught. The waggon is not so 

 ^well finished as the others. Price 32?. 10s. 



First Prize of 15?. to T. Milford and Son (4875), of Thorverton, CuUompton. 

 Second Prize of 10?. to W. Ball and Son (1306), of Rotlnvell, Kettering. 

 Highly Commended. — W. Glover and Sons (1567), of Warwick. 

 'Commended. — F. P. Milford (5036), of Kenn, Exeter. 



For Table XX., Paik-Hokse Waggons, see pp. 694-695. 



Class XXI. Light Waggons on Springs. — Four waggons were 

 entered, but only two were tried. These were loaded with 

 45 cwt. mangolds, and tested in the same manner as those in 

 the last class. In fact this class is similar to the last, differing 

 only in the use of springs ; therefore a good comparison of 

 the mean draughts of these two classes of waggons is formed, 

 and, as already explained, the mean draught was least in the 

 spring waggons. 



No. 1432. H. Hayes and Son, of Stamford. — The body framing is of oak, with 

 sides of elm planks. Its dimensions are 10ft. 5f in. x 4 ft. If in. x 1 ft. 7^ in., 

 its capacity is 69*5 cubic feet, and area over ladders for harvest purposes 100 "9 

 square feet. The body rests in front on two longitudinal springs and behind 

 on two longitudinal springs with a cross check-spring. The front springs are 

 rather stronger than the hind springs, being made up of eleven 2 j-in. x ^-inch 

 plates, 3 ft. 5 in. long, and curled upwards and inwards at each end. The 

 hind springs are made up of; ten plates of like constniction. The hind cross 

 check-spring has seven plates of the same dimensions, and is 2 ft. 8 in. long. 

 The springs are fixed to the axle-bed by two staples, which go through the 

 axle-bed and are screwed up at the bottom. A hooi) between these staples 

 keeps the springs together. 



When empty the oj)ening of the front springs was 4i§ inches, and that of 

 the hind springs 2i^ inches ; under a load of 45 cwt. these openings were 

 reduced to If inch in front and 4f inches in the hind springs, thus showing 

 deflections of 1 -f-^ inch and -/^ inch. The axles of the wheels are separate, 

 21 in. X I in. x 19 in. long, and fastened to the axle-bed by bolts 2f in. x 

 5 in. 



The diameter of the front wheels is 3 ft. 5 in., with 2° inclination to vertical, 

 and 12 spokes ; that of the hind wheels is 4 ft. 11 in., with 2i° inclination, and 

 14 spokes. The spokes are mortised into the felloes with a shoulder all round. 



A screw lever break is attached to the hind wheels. 



The fore carriage turns on two iron circular tables : this prevents undue 

 oscillation of the load when travelling on a rough road ; the waggon is also 

 easily turned on them. 



On the road the mean draught per ton of gross load was 46 "2 lbs., and per ton 

 of useful load 69 '8 lbs. ; on the field its mean draught per ton of gross load was
