Motion Picture Herald (Jul-Aug 1943)

July 24, 1943 BETTER THEATRES 93 strips at the stair risers are loose or are of improper type and size. The lining under the carpet on the stairs is flattened out thin or entirely worn away at the stair nosing. The fastening holes are not deep enough or of insufficient quantity. The entire stair tread may be loose, especially if it is a marble slab. It must be remembered that where carpeting is laid over a marble stair, constant trouble will arise if the treads and the carpet are not fastened down properly and solidly in place. It seems that too few carpet installation men know how to do this work properly. The trick is to drill holes in the marble slab without chipping or cracking it, and also to make them deep enough so that the wood plugs will hold. Using ordinary drills by hand is a long and tedious job, while electric drills will become dull quickly and even break. From the writer's experience it has been found that the drilling of marble and similar material, especially when the drill is fed by hand, can be done easily by grinding or filing a narrow slot in the point of the ordinary SIDE VIEW DRILL SLO" END VIEW 'IN 6 DETAIL drill. This slot should be about % or 34 inch deep, according to the size of the drill to be used, and cut at an angle a little less than 90° with the cutting edges. If the slotting is carefully done, the drill will give good results in making a clean, deep hole and prevent the cracking of the marble. CALCULATING YARDAGE In making an inspection record, the yardage may be ascertained conveniently by counting the number of either }i or 4/4 widths carpet is 27 inches wide and 4/4 carpet is 36 inches wide). Then measure the length of the largest breadth and the length of the shortest breadth in feet. Add the two lengths together and divide by 2 to arrive at an average. This average length should be multiplied by the total number of breadths and the result divided by three to get the number of "running" yards in the carpeted area of either 24 or 4/4 width carpet. Add about 8% of this total yardage for matching of the design and turn-under for the breadths. In good installations, the ends of each breadth of carpet, as well as the sides in the aisles (when not recessed in the floor) are turned under about 2 inches. In figuring the yardage of broadloom carpet the answer will be in square yards, as this carpeting comes in standard widths of 3, 6, 9, 12, 15 and 18 feet, by almost any length. This limitation of the widths of broadloom carpet is due to the standard sizes of the weaving looms.
