A simple puller may be easily made to 

 remove cones from either end of the arma- 

 ture-shaft without liability of damaging 



CIRCLE TO FIT BALL RACE 



Puller for removing bearing cones on au- 

 tomobile magnetos or lighting generators 



anything. The puller is made of bar stock, 

 either steel or iron, bent as indicated and 

 having the jaws shaped to conform to the 

 cur\'ature of the ball race and circle of the 

 cone. A tension bolt is used to hold the 

 puller-jaws firmly seated on the cone-ball 

 race and prevent their spreading. This is 

 curved or offset at the center to clear the 

 tension screw. When the parts are properly 

 assembled, screwing down on the puller- 

 screw which sets in the center hole of the 

 shaft end, will remove the most obstinate 

 cone in an effective manner. This same 

 type of puller, but of heavier construction, 

 can be used to remove ball bearing cones 

 from automobile front wheel supporting- 

 spindles as well. — Victor W. Page. 



Apply a Light Color to the 

 Kitchen Walls 



NEVER paint the kitchen walls a color 

 that will not show the dirt and dust. 

 A light color, such as light buff or a soft 

 gray putty color is cheerful and not glaring, 

 and it will make the owner work to keep 

 the dirt out. 



How to Make a Support for an 

 Automobile Frame 



A SIMPLE piece of garage and auto- 

 mobile repair-shop furniture that can 

 be made during spare time is shown in the 

 accompanying sketch. It is especially val- 

 uable in supporting the frame of an auto- 

 mobile when necessary to remove a spring 

 or axle, as the ordinary form of automobile 

 lifting jack cannot be used to advantage 

 under such conditions. 



The base is of cast iron, the mold being 

 made from a simple wood pattern. The 

 only machine work necessary is to bore out 

 the center and tap it to fit the pipe. A pipe 

 2 in. in diameter will be suitable for small 

 cars, though the 3-in. size illustrated is 

 better adapted to general requirements of 

 the average garage as it will sustain the 

 heaviest pleasure cars and practically all 

 trucks. The pipe is threaded at one end 

 and screwed in the base-plate casting. 



Sometimes an ordinary- floor-plate is used 

 by bolting it to a substantial wood block 

 or section of plank instead of the special 

 casting, though the latter is neater and can- 

 not crack or split. A series of ^-in. holes 

 are drilled through the pipe, these being 

 spaced as desired, usually 2 or 3 in. apart. 

 Another casting is made for moving on the 

 pipe. An arm projects as shown. 



No machine work is needed except tap- 

 ping out for the i-in. set-screw, as the 

 large hole through which the pipe passes 

 may be cored in the casting to save expense. 

 To make doubly sure and prevent liability 



Frame support or jack to use in places 

 where an ordinary jack is not adaptable 



of set-screw slipping under a heavy load, 

 a stop-pin is also provided, this passing 

 through holes in the pipe and slots in the 

 casting. This stand is useful in supporting 

 front and rear axles for repairs and also for 

 holding bar-stock when pieces are to be cut.
