invalids' jumpers. 187 



attached to a bed-post, a nail, or some part of the room, will 

 prevent them. 



The spring was first applied to this purpose by the factory 

 operatives at Naugatuck, \\hen the apparatus was made in a 

 rude way, after the plan of fig. 4. The springs were next put 

 in market for sale The fanciful arrangement of the hoop was 

 invented and patented by a gentleman in New York.* 



The springs may be obtained at the shops, at a low price, and 

 trimmed by any person according to their own taste and means. 



Care should be taken when the child is suspended from a hook 

 in the wall, that it is strongly fastened, as the consequences of 

 neglect to do this have sometimes proved serious. 



SWINGS. 



The seats of these swings are covered with gum-elastic vel- 

 lum, vegetable leather, or cushioned with gum-elastic sponge 

 fabric, so as not to be injured by exposure to the weather. 



A spring of elastic cordage is inserted in the strap or rope, in 

 the manner represented in the plate, figs. 10 and 11, which gives a 

 perpendicular, as well as a backward and forward motion to the 

 swing. 



INVALIDS' JUMPER. 



This is made on much the same plan as the springs above 

 described, except that a chair is used instead of a seat, as repre- 

 sented in the plate, figs. 12 and 13, with hand straps attached.
