. British bee journal & bee-keepers adviser. Bees. March 1-^, 1913.] THE BRITISH BEE JOURNAL. 105 The top end must be shaped i\.s shown at H, Fig. 2, as it is intended to support the barrel. This piece as well as the hand- guard can now be riveted to the support, F, G. At fin. from the end corresponding to the hole in the barrel, punch a |in. hole to allow the bkst-pipe to pass through. The support is now ready to be fixed to barrel by means of two rivets, seen in Fig. 1. The grating, L, is of. FIG. 2. sheet-iron, with -Jin. holes punched closely all over it. Two strips of sheet-iron, ja^n. wide, are riveted on in the shape of a cross and turned down at right angles to form legs, M, which much be l^in. long. Before putting in the grating, spring the legs out a little, so that when pushed down the barrel it will be kept in position. AVe will next make the springs. There is nothing better for this purpose than No. 16 brass spring wire; and this, together with the shape, is what makes the Bingham bellows work so smoothly and FIG. 4. pleasantly, without fatiguing the hand of the operator. The best way to make them is to drive into the edge of a piece of inch board two iron pins ^V"- '" diameter, and projecting about |in. Cut your wire 14in. long and lay it on the board against the iron pins, so that both ends project the same length beyond them. By referring to Fig. 6 it will be seen that the end, P, is turned to the right over pin a, and the end 0 to the left over pin b. Each end must have two complete turns and part of a third turn until the ends P and O stand at right angles, in the position shown in Fig. 6. The wire is then taken off the pins and bent at N, until the two spirals meet and thie wires P and O are brought in contact with each other, as shown in Fig. 7. Close to the coils give the wires a slight bend, seen in Fig. 8, which shows the spring w'hen it is slightly pressed down, as it would be when between the two boards of the bellows. The spri
