Look into the Mysteries of a Mold Here It Is! The Adjustable Player- 

 with an Electric Trowel Piano-Bench and Record-Holder 



OUT in Brainerd, Minn., lives Thomas 

 A. Gatten, an 



expert molder, who 

 fussed in the semi-darkness of an iron 

 foundry, trying to get 

 the sides of his mold 

 just right. Sometimes he 

 captured a little extra 

 light by the bothersome 

 expedient of holding a 

 hand-mirror with his left 

 hand while he worked 

 with his right. Thou- 

 sands of other men have 

 done the same for years, 

 and at the same time 

 have made remarks — ■ 

 strong remarks. 



One day, a bright idea 

 came to Gatten while 

 he was at work in some 

 dark corner. Why not 

 illuminate the mold by electricity ? With 

 this thought he set to work and in- 

 vented a little electric lamp and bat- 

 tery to be sunk into the handle of his 

 trowel — or into any other tool handle 

 for that matter — that would furnish light 

 where it was 

 needed and when 

 it was needed by 

 the mere pressure 

 of his little finger, 

 as shown in the 

 cut. Lights off — 

 you have the 

 ordinary molder's 

 trowel, except that 

 the end of its han- 

 dle is decorated 

 with a powerful 

 little bull's-eye. 

 Lights on — and 

 you have a chance 

 to see just what 

 you are doing in a 

 dark hole. Gone 

 is eye-strain, in- 

 efficiency and the 

 necessity for strong 

 language. Mr. 

 Gatten has given 

 the world another 

 of the little things 

 that count.

HE combination piano-bench and 

 record-holder shown in the accom- 

 panying illustrations is heavy enough 

 to be perfectly rigid, 

 it will always remain 

 position when in use. 

 t it is easily moved 

 from its place 

 and pushed 

 back against 

 the wall out 

 of the way. 

 This is done 

 by means of 

 casters, which are easily 

 moved into place under 

 the four legs, by pressure 

 on a lever.

Inside the frame, partitions accommodate 

 sixty records. Each record is easily reached 



to the framework, 

 and is covered by 

 the top covering- 

 boards when not 

 needed. When the 

 seat is to, be used, 

 the covering- 

 boards slide back 

 and down, and the 

 seat is raised to 

 any convenient 

 height. Inside the 

 frame, there are 

 partitions to ac- 

 commodate sixty 

 records. The seat 

 slides along frorh 

 one end of the 

 frame to the other, 

 so that tho oper- 

 ator can select his 

 record without get- 

 ting up.
