Device to Hold Covers on Sleeping 

 Child in Crib 



SEW a one-eighth-inch wire to outside 

 cover of bed — a spread or quilt or 

 sheet. Sew a piece on each long side 

 and on the short side at the foot of the 



The most restless baby cannot pull this coverlet 

 off because it is securely fastened on both sides 



crib. Tie the wire with tape to the rod 

 on the bedstead that parallels the wire. 

 Small rings can be put on the wire 

 about twelve inches apart if de- 

 sired. To open covers, untie the 

 tape. 



The other covers are held in 

 position simply by pinning them 

 all to the top one in two places. 



s[)eefl it works best. It will do the work 

 of about twenty men. 



The front end is taken up by the 

 sweeper mechanism, located in front of a 

 pair of wheels, which, in turn are, 

 practically speaking, in front of the 

 motor-cycle proper. Both wheels and 

 sweeper mechanism are fastened to the 

 motor-cycle by means of an angle-iron 

 frame, the operation of the wheels being 

 controlled by the handlebars. The 

 brush, which is about sixty inches in 

 length, is immediately in front of the 

 pair of wheels and is operated by a lever 

 at the side of the driver, who, by pushing 

 one of the levers forward raises or lowers 

 the brush at will. The cylindrical sheet- 

 iron drum, with an apron attached, is 

 suspended just in front of the brush. 

 Over this apron the dirt is swept into 

 the drum, the brush being chain-pro- 

 pelled by the engine of the motor- 

 cycle. 



By pressing forward another lever the 

 driver is able at a moment's notice and 

 without dismounting to turn the drum, 

 which has a capacity of about four 

 bushels, so that its contents will fall 

 in a pile upon the street. 



Provision has been made for this 

 sweeper to carry along its own dirt- 

 wagon. This is done by simply 



The Motor- Cycle Street- 

 Sweeper 



AN innovation in street- 

 u sweepers has just ap- 

 peared in Los Angeles, Cal- 

 ifornia. It is the combined 

 invention of T. C. Girton, 

 F. C. Hoffer and J. F. 

 Smedley of that city and is 

 a combination of an ordi- 

 nary twin-cylinder motor- 

 cycle and a sweeping aji- 

 paratus. The engine in the 

 motor-cycle furnishes the moli\-e power 

 by wliich the entire outfit is driven. 



It is a one-man machine, while the 

 gasoline, oil and brush, which are its 

 only other continual expenses, are hardly 

 large enough to be worth mentioning. 

 It may be operated from two to twenty 

 miles an hour, while at the eight-mile

fastening that part of the outfit to the 

 rear of the motor-cycle. If at an>- time 

 the sweeper mechanism should gi\e any 

 trouble, the simple pushing forward of a 

 lever at the tlriver's side lifts a metal tray 

 which covers the brush and receiving 

 side of the drum, placing it immediately 

 oi)en for examination.
