In Fig. 30 are shown a plan (a) and an elevation (b) of a quarter-platform stairway with 4 risers in the flight adjacent to the landing, close paneled and molded stringers, 6-inch square newels, 2 1/2-inch turned and square base balusters, and a 4" X 41/2" double molded hand rail, with ramp and knee, or goose neck, connection with newels. In the plan, a and b are the principal floor-beams of the platform, and c is the top landing floor-beam. In drawing the elevation, the first step is to locate the treads and risers as shown by dotted lines. The balusters may be placed at any distance apart that is desirable on close stringers, as their relation to the treads is not noticed. On the plan is shown their relation with reference to the newels from which measurements should be taken.
Observe, in the elevation of the lower newel, that there are two risers at right angles to each other at the center of the newel, one riser being from the top step of the lower flight to the platform, and one riser from the platform to the first step of the short flight, as shown at d e f. In this elevation the portion d h e' h" is the elevation, or side view, of the short flight, from d to e on the plan (a). A cross-section of the close stringer, showing the panel, timbers, blocking, etc., is shown at D, and from this the connections with the newels are lined in as indicated. The section H along the floor level is the same as at D, but if this should prove at any time to be too high above the floor, the panels may be reduced in width. Panel work of this character may have stiles at newel connections, and mun-tins at suitable intervals in the long flights and landing facias.
