A Convenient Metal Holder for 

 Milk Bottles 



JUST where the milk bottles go and 

 what becomes of them is difficult for 

 some housewives to determine. The illus- 



trations show a 



very handy httle 

 receptacle for the 

 bottles. It can 

 easily be made in 

 any home work- 

 shop. The base is 

 manufactured out 

 of an old coffee 

 can cover, the top 

 or spring catch 

 portion being sim- 

 ply an old piece 

 of sheet brass, 

 moulded or form- 

 ed over a round 

 bar. When the 

 old bottle is emp- 

 ty, it is slipped 

 into the de\'ice 

 and the milkman 

 on his round replaces it with a full one. 

 The holder can be placed anywhere on 

 the side of the house, or near the door, 

 low enough so that it can be easily 



The bottle of milk is 

 easily set in holder 



The sheet metal parts are made the cor- 

 rect size to hold an ordinary quart bottle 



reached, yet high enough to protect the 

 bottles from accidental upsetting or from 

 being knocked out. — F. W. Bentley, Jr.

A Work Bench Clamp to Hold 

 Boards for Planing 



THIS very handy clamp or vise is 

 easily made of oak or other suitable, 

 hard wood. It consists of three pieces 

 and a disk. The pieces are 9^2 in. long; 

 one is 1)4 in. wide and 13^2 In. thick; the 



WorK Bench- 



The disk rolls on the sloping part of the 

 groove and clamps the board by pressure 



base of the other part is 33^2 in. wide and 

 1 in. thick with a cap of the same width 

 and I2 in. thick. The disk is 2 in. in 

 diameter and slightly under 1 in. in 

 thickness. A wedge-shaped notch is cut 

 in the piece that is 1 in. thick, so that 

 the larger part admits the full size of 

 the disk, the smaller part sloping down 

 almost to a point. The pieces are fas- 

 tened to the bench top as shown, with 

 a space between them of 1)4 in., and 

 with the disk in the notch. 



It is apparent that when a board is 

 placed edgewise in the open space, while 

 the disk is in the larger opening of the 

 notch, it will be free, but upon pushing it 

 forward the disk will roll against the slop- 

 ing part, and wedge or clamp it. The 

 more pressure applied, the tighter will be 

 the grip on the board. When it is pulled 

 back, the action is reversed and the board 

 is easily withdrawn. — Robert Haxley. 



Solution for Cleaning Polished 

 Brass Quickly 



THE following solution will clean brass 

 faucets very quickly, without injury 

 to the hands or the metal. Put 13 2 oz. 

 of alum in one pint of boiling water, and 

 rub the solution on the brass surface with 

 a cloth. The stains, as well as the tarnish, 

 are quickly removed. The solution is in- 

 expensive and easily made.
