Lubricating Automobile Spring 

 Shackles and Bolts 



SPRI NG shackles, or hangers, are good 

 examples of automobile jiarts that 

 are obscured by other parts so that the\' 

 are sometimes overlooked or forgotten 

 when oiling time comes. These jointsform 

 the connecting links between the springs 

 and the frame, and they must support 

 the weight of the frame, motor, body and 

 passengers. The length of the spring 

 varies with the degree of deflection, so 

 that the spring shackles swing back and 



GREASE CUP 



Grease is forced through a hole drilled in 

 the bolt that secures the cup in its place 



forth, developing friction at all joints. 

 To prevent the wear on these bearings 

 it is necessary to provide an ample 

 supply of lubricant. These joints are 

 partly, if not wholly, covered by the 

 front and rear fenders, and failure to 

 care for them properly is often the cause 

 of annoying squeaks and rattles. 



A simple method of lubricating them 

 employs the grease-cup as illustrated 

 in the drawing. A small hole is drilled 

 in the bolt connecting tlie grease-cup 

 with the center of the bearing surface. 

 The grease is forced through this hole 

 to the bearing surfaces when the cup 

 top is screwed down. The cups should 

 be filled with a good cup-grease and then 

 turned down until the lubricant is 

 forced out to the bearing. This should 

 be done after every 500 miles; or, better 

 still, on a certain set day each week. At 

 least once a season the spring bolts 

 should be removed and thoroughly 

 cleaned. The hole through which the 

 grease is fed should be cleaned out with 

 a wire and flushed with gasoline. 



A Pocket Flash-Lamp on the 

 Bicycle-Handlebar 



ASIMPLE and inexpensive bicycle 

 light may Ijc made by welding to- 

 gether two hose-clamps, such as are used 

 on garden hose, 

 one clamp being 

 fastened to the 

 handlebar and the 

 other to a pocket 

 flashlight, as 

 shown. The two 

 clamps should be 

 riveted together 

 <uid then welded 

 with oxy-acetyl- 

 I'ne or brazed. A 

 flashlight mount-

cd in this way gives very good service. 



Fillers for the Pedal Slots of 

 Automobiles 



THE front seats of an automobile, 

 while highly prized by everybody, 

 are not usually the most comfortable, 

 because in summer the heat of the motor 

 is felt through the floor-board and in 

 winter the cold is more perceptible there. 

 This is especially true of the Ford car, 

 which has four large slots in the floor- 

 boards, where the pedals and brake-lever 

 are located. 



To close these slots a simple filler 

 plate has been devised, which fits under 

 the floorboards and holds a piece of 

 rubber over the openings. The rubber 

 sheet is slit to allow the shanks of the 

 pedals to pass through so as not to inter- 

 fere with their operations; but theslitsare 

 barely long enough to serve their purpose 



Slots of a pedal plate covered by a rubber 

 sheet so as to prevent unpleasant drafts 



leaving no space for air to enter. 



Asbestos felt boards may also be used 

 to insulate and make draft-proof the 

 under sides of the floor-boards.
