Hermes Handbags

 
for some years past. The plates of the boiler, which are the original ones and have never been repair< d at any part, are all good, and the grooving has not taken place at the butt-joints, a little irregular pitting alone being vHermes bagsisible on the inside of the plates. The boiler has now been cut up only on account of the engine being abandoned from the great length of time it has been worked. The remarkable contrast shown by the freedom of the butt-joints in this boiler from the grooving so universal with the lap-joints in the ordinary boilers appears only to admit of being accounted for by the difference of construction of the joints in the two cases. InBirkin another engine of the same class, which was last broken up• after attaining the maximum mileage of 313,000 miles, the boilerplates were very badly grooved at the angle-iron joint at the smoke-box end, showing that this part of the boiler remained as defective as in the ordinary boilers, the construction being the same as regarded this joint; while the rest of the joints being butt-joints were free from the grooving.
The flangHermes outleting, bending, and welding of the thick-edge plates for forming the boiler barrel are performed by the aid of machines specally designed for the purpose, which are shown in Figs. 2160 to 2172.
The Flanging Machine is shown in Figs. 2160 to 2162. It consists of a horizontal table A, on which the thick-edge plate, shown black, having been previously heated, is&nbsp;laid&nbsp;and secured by clamps, being pushed forwards against the adjustable stop B, Figs. 2161, 2162, so that the thick edge projects beyond the edge of the table to the required extent for forming the flange. Th roller C is then brought down with a slow motion by the eccHermes Birkin entrics D, ns shown Hermes Kellyin Fig. 2161, being firmly held by guides E at each end in the frame of the machine; and the edge of the plate is thus gradually bent down to form the flange. The table A is made to slide upon the bed F of the machine, and is set up by adjusting screws G to the required amount of clearance from the bending roller B, according to the thHermesickness of the plate to be flanged. The front edge of the table is faced with a separate wrought-iron or cast-iron edge-piece I, which can be removed and changed for another having a different curve for the edge, according to the curve that is desired in the neck of
the flange. The holding-down bar H is screwed down tight upon the plate, immediately behind the edge of the table, so as to hold the plate down flat on the table while the flange is being bent by the roller. The woHermes Handbagsking speed of this machine is seven double strokes per minute.
The Bending Machine, for bending the thick-edge plates into the semicircle to form the boiler barrel, is shown in Figs. 2163, 2164. It consists of three horizontal rollers, of which the two lower ones
