LIFE-SAVING NET. For bottom of elevator shafts. Astrong rope net, F, held on two sides by the rods, G, which are in turn supported on each end by thestrut arms C. The lower endsof these arms fit the bearingsin the pillow blocks, B, whiche are bolted to a stout plank, A,which is securely fastened tothe bottom of the shaft. Thenet is held taut by a large com-pression spring, E, acting at theupper ends of the strut arms C. The spring, E, is supported and heldin place by pieces of large pipe, D, it being also free to move alongthe same. When the falling body strikes the net, the fall is broken by the com-bined action of it and the springs which take the position shown by thedotted lines in the vertical 894. REMINGTON TYPEWRITER. Vertical transverse sec-tion of the No. 3 machine, showing the arrangement of the keys, key levers, and the upper part ofthe main frame of themachine is arranged aring to which areclamped loops in whichare pivoted the typearms. There are inthese machines as or-dinarily constructedfrom 38 to 42 typearms, each one bearingat its free extremity a diehaving on its face twocharacters, an upper and a lower-case type, figures, and punctuationmarks. The type arms are pivoted relative to the ring so that thecharacters which they bear all strike exactly in the same place. Thetype arms have hardened steel pivots which are ground to a bearing,thereby insuring accuracy in the movement of the levers.
