Using the Automobile Jack to 

 Straighten a Frame 



IN machine shops employes are often 

 forced to rig up all sorts of make-shift 

 arrangements for unusual jobs. One of 



An "old man" arrangement used with an or- 

 dinary jack to straighten a chassis frame 



these is shown in the accompanying illus- 

 tration, which depicts a helper straighten- 

 ing a bent side-frame member of a large 

 automobile by means of an ordinary 

 ratchet-jack. The manner in which the 

 work is done can be clearly seen in the 

 illustration. 



Celluloid Makes a Superior Stencil 

 Cutting Base 



WHILE cutting out a stencil, I picked 

 up a celluloid triangle to use as a 

 base. I found it to be superior to wood or 

 glass for the purpose, as wood has ofttimes 

 hard streaks that resist the smooth progress 

 of the knife, and glass will dull the blade. 

 Celluloid is even in composition and allows 

 the knife blade to penetrate it just far 

 enough to leave the cut without any 

 projecting edge. — James M. Kane. 



Making a Handy Pencil-Holder 

 of a Board 



TAKE a board 8 in. long, 5 in. wide and 

 I in. thick and saw it diagonally from 

 one corner to its opposite, making two 

 triangles of it. Into the side of one, bore 

 5^-in. holes spaced about 3^ in. apart to 

 within ^ in. of the bottom, using the 8-in. 

 way as'the base. Secure this in a convenient 

 place on the work-bench. It will hold 

 almost any length of pencil. 



Sh2et Metal as a Substitute for 

 a Small Nut 



THE loss of a small slotted nut on light 

 machinery, such as that of a motor- 

 cycle, automobile or motorboat means a 

 stop until a duplicate may be had. Parts 

 of this nature are not easily 

 found, but a substitute may be 

 formed of sheet metal or a piece 

 of tin, which may be obtained 

 from a tobacco or a fruit can. A 

 piece of the metal is folded over 

 back and forth five or six times, 

 then the folds are punctured 

 with a nail or punch. Each sep- 

 arate layer is worked over the 

 thread as shown. When this 

 substitute is turned up tight, it 

 will not work loose like the ordi- Nutmadeof 

 nary nut. — Ronald F. Riolet. a tin strip 



A Convenient Tag-Holder for the 

 Shipping-Room 



THE illustration shows the details of a 

 very handy and convenient shipping 

 tag-holder. A number of tags are dropped 

 into it the long way. As a result of the 

 bend and flare at the end it is impossible 

 for more than one card or tag to be thumbed 

 out at one time. A number of these were 

 put up in a shipping department of a shop. 

 The arrangement was soon recognized as 

 very convenient by the billing and shipping 



Ho'.der for shipping-tags to keep them ar- 

 ranged so that one can be taken out at a time 



clerks, who, before its installation, were 

 always losing time and temper securing 

 tags. — F. W. Bentley.
