THE USE OF RUBBER IN PAINTING MACHINES. 



'|>,<f|,t6HAt*-,, 



DURING the construction of the World's Fair buildings 

 at Chicago, nine years ago, a certain inventive genius 

 who stated publicly that he proposed to paint the 

 buildings by machinery was mercilessly ridiculed. 

 The " knowing ones," however, saw buildings which it was 

 estimated would take four months to paint by hand, thor- 

 oughly and durably painted in one week by machinery. The 



paint was sprayed on 

 the building through 

 India-rubber hose 

 from tanks, from 

 which it was expelled 

 by means of com- 

 pressed air. An il- 

 lustration of this pro- 

 cess, by the way, ap- 

 peared in The India 

 Rubber World of 

 July 15, 1893. Since 

 that time, thousands 

 of painting machines 

 have come into use, 

 involving many ad- 

 vantages, not the 

 least of w h i c h , of 

 course, is economy, 

 and the subject is re- 

 ferred to here for the 

 reason that without 

 the help of the rub- 

 ber manufacturer in 

 supplying the flexible 

 hose needed the new 

 method of painting 

 neverwould have 

 been possible.

as a preservative of 

 both woodwork and ironwork is, of course, universally con- 

 ceded. In these days of large structures, not only is the cost 

 of paint very large, but the expense of scaffolding, brushes, 

 labor, and so on, adds enormously to the expense of painting 

 over a great structure. These ma- 

 chines are being used for the paint- 

 ing of factories, breweries, distil- 

 leries, hospitals, stables, green- 

 houses, packing houses, power 

 plants, steamships, railway stations, 

 freight cars, tobacco warehouses, 

 plantation buildings, and sheds and 

 houses in general. The catalogues 

 of the firms manufacturing painting 

 machines contain the names of hun- 

 dreds of customers, including such 

 concerns as the Standard Oil Co., 

 the New York Central Railroad Co., 

 the United States Sugar Refining 

 Co., the Singer Manufacturing Co.,

and so on, the inference being that if such concerns find it ad- 

 visable to use these devices, their competitors must also find 

 themselves obliged to use them. 



As may be supposed, painting by machinery requires speci- 

 ally prepared paints. The machines are not recommended for 

 use with heavy oil 

 paints — that is, 

 those whose base 

 is white or red 

 lead mixed with 

 heavy linseed oils 

 — for the reason 

 that these ingre- 

 dients, being of a 

 sticky, gummy na- 

 ture, clog up and 

 prevent satisfac- 

 tory spray work- j 

 ing. It is known 

 that the thinner 

 the coating ma- „. . ... -.u . j u , j

provided that they 



thoroughly cover the surface, the neater, more lasting, and sat- 

 isfactory the work will be. The thicker the paint is put on, the 

 more liable it is to crack and fall away. It is found by exper- 

 ience that paint can be more evenly distributed by means of 

 machinery than in any other way, besides which it can thus be 

 applied in many places which cannot be conveniently reached

in painting with brushes by hand. One of these machines is 

 stated to be capable of doing the work of from eight to twenty- 

 five men in a given length of time. 



In the operation of the pneumatic coating or painting ma- 

 chines each is supplied with a length of suction hose — usually 

 5 feet, one inch, wire wound, provided with a strainer — to con-
