X y2 in., in position, with its upper edge 

 just under these screws, locate the two 

 points for its pivoting screws. This is 

 clearly shown in the illustration. The 

 pivoting screws will work more easily if 

 the holes are first made with a slightly 

 larger screw. The back screws hold the 

 shelf in a horizontal position when it is 

 being used. At other times, it can be 

 raised to a vertical position between the 

 posts. 



The top and bottom pieces on the 

 right side have the same location as those 

 on the left. The second cross-piece is lo 

 ins. from the tops of the posts. Just 

 under it is attached the piece 12X x 3>^ x 

 14. This piece does not need to be 

 nailed ; glue will answer. Attached to its 

 under edge and projecting forward 

 horizontally, is the narrow strip, 12X x 

 Yi, -x. yi. Attached to the front edge of 

 this piece, and slanting forward oblique- 

 ly, as shown in the illustration, is the 

 piece, I2>< X i^i x X- These three 

 pieces should be nailed to one another 

 with two or three fine wire nails, which 

 can be readily concealed. 



The third cross-piece on the right is 

 i8>^ ins. and the fourth piece 27 ins. 

 respectively, measured from the tops of 

 the posts. Before joining them to the 

 uprights, they should be fitted with 

 brass pins, as shown. The top piece 

 should be provided with hooks. 



Before proceeding further, the various 

 parts should be varnished, stained or 

 painted, according to individual taste. 

 If the screen is to be used in a bedroom 

 having white woodwork, white enamel 

 may be used to advantage. If the wood- 

 work is mahogany or oak, the screen can 

 be finished to match. After the parts are 

 thoroughly dry, the leather or other 

 covering is put on. If leather is used, 

 it should match not only the finish of the 

 screen, but the color scheme of the room. 

 If white enamel is used, a pretty chintz 

 pattern is very effective as a covering, 

 or silk may be used. In putting on the 

 leather or chintz, be careful to stretch it 

 tightly over the frame, gradually pro- 

 ceeding from top lo bottom, inserting the 

 tacks on both sides simultaneously. The 

 edges should be foldid in about K in.; 

 and the tacks should be driven into the 

 middle of the frame. If silk is used, it 

 may be shirred on a cord at the top and

bottom, instead of being tacked. The 

 two inside strips which form the pockets 

 at the bottoms are attached by turning 

 in their edges and tacking on the inside. 

 The measurements given are large 

 enough to allow for folding in the upper 

 edges several inches. 



Lastly, fasten two small brass hinges 

 on the back, yj/^ ins. from the top and 

 bottom, respectively. On the front, 

 attach a hook and eyebolt, i8>^ ins. from 

 the top, for holding the two parts of the 

 screen together when not in use. On the 

 top cross-pieces fasten two brass han- 

 dles, as shown. They should be near the 

 front inner edge of the frame, so that 

 they will come together when the screen 

 is closed. 



Fitting Windows With Weights 



IN the illustration is shown the way in 

 which seventy-five windows in a 

 factory building were fitted with sash 

 cords, pulleys and weights. The method 

 is simple, inexpensive, neat and the pul- 

 leys and weights are out of the waj'. The 

 upper end of the window frame is cut 

 away at an angle as shown, just enough 

 to make a seat for the pulley. This brings 

 the weight in the corner at the inside edge 

 of the window frame and against the 

 building wall. The other end of the 

 rope is fastened to a screw-eye in the 

 top of the window sash. These weights, 

 when out of order can be repaired by 

 anyone. — M. E. Duggan.
