How to Change an Ordinary Chair 

 Into a High Chair for Baby 



LL. FARRER, of Welland, Ont., had 

 . three little children of high-chair 

 age in his family, but only one high chair. 

 This set Mr. Farrer thinking and eventu- 

 ally the idea of constructing a contrivance 

 for . temporarily changing a low into a 

 high chair took definite form in his mind. 

 After a number of disappointing attempts 

 he evolved the invention pictured. 



The .contrivance consists of a wooden 

 seat which can be attached to the back 

 of an ordinary chair by hooking the heavy 

 wire connected with each folding armrest 

 over the back. By turning the spiral of 

 the hooking arrangement the height of 

 the seat can be adjusted to the require- 

 ments of the child using it. When the 

 seat is not in use it can be folded up so 

 as to take but little space. 



poultry without the aid of a human hand. 

 The barrel shown in the accompanying 

 picture contains water which drips from 

 the spout very slowly into the tilting 

 bucket below. A suitable valve regulates 

 the rate at which the water drips into 

 the bucket. It takes eight hours for the 

 bucket to fill. When full it tilts and 

 dumps the water into a trough. 

 From the trough the water flows 

 to a basin, from which the 

 chickens drink. Attached to 

 the weight suspended from 

 the tilting bucket are bells 

 which jingle as the bucket is 

 overturned and remind the 

 chickens that meal time has 

 come, quite in the best 

 boarding-house style. The 

 feed is likewise supplied at 

 regular intervals automatically, 

 from the large can which sur- 

 mounts the apparatus. It flows 

 through a spout into the hopper, 

 and thence on to a curved delivery plate 

 which scatters it in all directions just 

 as if it were thrown out by hand. 



The tilting of the water bucket when 

 it is emptied supplies the motive power 

 for operating the device and once started 

 it requires no attention. 



Feeding and Watering the Chickens 

 Automatically 



DON'T scatter chicken feed by hand. 

 It is a waste of time nowadays. 

 Nikilas Lappas, of Salem, Massachu- 

 setts, has patented a machine which 

 does the work and never forgets. At 

 regular intervals his apparatus delivers 

 measured quantities of water and feed for
