and are perspective views of a portionbf the base 2 ancl cover 3. v

Thebase 2 is a sheet 1netal stamping with a raised central Portion as"can be seen in Fig. 3. The slots 6 sind 7 cnt in the base 2 zu*e aclapted 130 receive the hinge 1nembers 4 ancl 5 which are nveted on the cover The: cover 3, wlnch also 1s macle of sheet metal hfis a box like shape zind is open" in the rear. 1n0rder to place the coyer 3 on. ehe base 2, the former 1s rotatecl from 1ts pos1tmn 111 Fig. 2 about an axis formed by a line run ni1ig; through the hinge 1nembers ancl 5 until the plane 0f the cover is approxnnately atiight angles t0 the plane 01 thefbase 2,

The cover 1s 1noved downwarcl Slightly cause the projections 17 und 18 of the hinge n1ernbers 4 anal 5 to come behind and below the lower edgjes' 0f tlie slots 6 ancl 7 as shwn in Fig. 5 so 215 to prevent the cover 3 .fronmbeing pullecl away from base 27 The catch 8 is now rotated about ite pivot in a counter-clockavism direction until the projection 19 thereof strikes t he" raised portion 10 of the base. In thiS posi'tion ehe catch 8 preve'nts the hinge 5 from moving up The cover 3 may now be swung shug,
