 Why Not Take Your Nightly 

 Rest in Your Library Table ? 



NOT so many years ago, 

 when apartment dwell- 

 ers first began to feel the 

 pinch of space limitation in 

 their diminutive quarters, 

 combination furniture was 

 all the rage. Anyone visiting 

 a flat dweller could never feel 

 quite sure whether the book 

 case he admired in the parlor 

 was really what it seemed to 

 be or a bed in disguise. Beds 

 are such cumbersome things. 

 Put a bed in a room and the 

 room becomes a bedroom, 

 the privacy of which excludes 

 outsiders as a matter of 

 course. From the very be- 

 ginning, inventors have therefore concen- 

 trated their efforts upon the problem, how 

 to disguise the bed, as it was clearly im- 

 possible to eliminate it altogether. Some 

 of the attempts were quite remarkable, 

 but few were practicable. Rather original 

 is the combination of a library table and 

 bed shown in the picture, an invention 

 by E. T. Bronsdon, Chicago. By a few 

 simple operations, the solid-looking li- 

 brary table in the parlor or studio can be 

 changed into a comfort- 

 able and sanitary double 

 bed fitted with sagless 

 springs and felt mattress. 

 This seems to be one of 

 the most practical sug- 

 gestions, so far, for sav- 

 ing space.

The loom that weaves a diagonally reinforced fabric is a

A Fabric With Diagonal Reinforcing 

 Threads, Useful for Automobile Tires 



THE urgent need of a cotton material 

 which will meet the requirements of 

 a tire foundation (flexibility, strength and 

 resistance to strains in the direction of the 

 threads and diagonally) stimulated Mr. 

 William G. Trautvetter of Paterson, N. 

 J., to invent a loom by which it is possible 

 to weave a cotton fabric with diagonal re- 

 inforcing threads. The 

 picture shows the per- 

 fected loom, which is 

 remarkably compact. 

 The diagonal 

 threads are carried in 

 spools mounted in a 

 large reel. As the reel 

 revolves, the threads 

 of the upper half are 

 moved across the fab- 

 ric in one direction, 

 while those of the low- 

 er half are carried in 

 the opposite direction, 

 diagonally across the 

 fabric. The filling or 

 weft threads always pass under the 

 warp threads, and over the bias threads. 

 Since the diagonal threads are interlaced 

 with the warp threads, while the weft 

 threads are intermeshed with the warp 

 and with the diagonal threads, a fabric 

 is produced which is remarkably strong 

 in every direction.
