THE INDIA RUBBER WORLD 



[August 1, 1912. 



NEW TRADE PUBLICATIONS. 



" I 'HE Bristol Co., Watcrbury, Connecticut, has recently issued a 

 ■*• handsome 64-page catalog 8 inches x lOj^ inches, carefully 

 printed on heavy-coated paper. The catalog contains a great 

 many half-tone illustrations of the recording pressure gauges and 

 vacuum gauges made by the company, some of these cuts filling 

 almost a page and showing in minute detail the characteristics 

 of these gauges. 



This catalog, which, by the way, is No. 1000, lists all of 

 the Bristol company's recording and vacuum gauges except the 

 round form models 50, 52 and 56, which arc shown in bulletins 

 issued earlier by the company. 



The illustrations not only show gauges as generally used, but 

 show them in portable form and in waterproof and moisture- 

 proof cast-iron cases. Some of the illustrations show the con- 

 struction of the gauges, making very clear the simplicity of their 

 construction. An interesting illustration that occupies two pages 

 is a full-size fac-simile section of a 12-inch chart, with record of 

 draft in sack for B & W boiler in the power plant of an elec- 

 tric light and power company, as recorded by a Bristol recording 

 vacuum gauge. Twelve pages of the catalogue are devoted to a 

 list of names of some out of the 25,000 users of the Bristol 

 gauges. 



The B. F. Goodrich Co., Akron, Ohio, has issued a large sheet 

 printed on a sort of parchment paper 22 inches by 34 inches in 

 size, which folds into Syz-'mch x 11-inch folder. It devotes 

 half of its space to reproducing a number of letters received from 

 members of the trade, complimenting the Goodrich Co. on its re- 

 cent price reduction. The rest of the folder is given up to show- 

 ing, in the form of large half-tone cuts, some of the more recent 

 styles of automobile tires manufactured by this company, among 

 them the Goodrich Master Tread tire, the Goodrich-Bailey Tread 

 and the Goodrich Metal Studded tire. 



The Diamond Rubber Co., Akron, Ohio, has recently mailed the 

 trade a folder about 6 inches x 10 inches, which opens out into a 

 large sheet and shows cuts, standing nearly a foot high, of three 

 of its famous tires — the Safety Tread, with rubber "Squeegee" 

 bars ; the Grip Tread, with steel rivets, and its smooth tread tire. 

 The folder carries this motto ; "We could build them cheaper — 

 but we won't. We would build them better — but we can't." 



The United States Tire Co. has issued No. 9 of its maga- 

 zinette called "U. S. for Us." This is a little publication in- 

 tended for home consumption by the employes of the United 

 States Tire Co. It is full of encouragement for the members of 

 its selling force, and gives sage advice as to the methods by 

 which their success may be increased. 



The Portage Rubber Co., Akron, Ohio, is distributing a taste- 

 ful little pocket catalog called ''Portage Tires." It illus- 

 trates a number of the best-known tires made by this company 

 and describes them. The little book contains an "Inflation 

 Table," together with a table showing the carrying capacity of 

 the company's tires, and gives the price list now in effect. 



The Combination Rubber Manufacturing Co., Bloomfield, New 

 Jersey, issues a little booklet 3j4 inches by 6 inches, of 32 pages, en- 

 titled "A Condensed General Catalog." The name indicates its 

 character. It describes, without illustration, the various products 

 of the company, including rubber belting, garden hose, suction 

 hose, air-drill hose, brewers' hose, acid hose, rubber valves, 

 couplings, tubing, mats and sundry other rubber goods. 



The Frontier Tire and Rubber Co., Buffalo, New York, issued 

 about the 4th of July a little card appropriate to the season of 

 special patriotism, as on its front side it shows the American 

 Flag waving in the breeze, while on the other side it gives some 

 tables which the owner of the automobile will find convenient 

 for reference. These tables show the correct pressure for tires, 

 interchangeable tire sizes and the proper tire inflation. 



The Westinghouse Electric and Manufacturing Co., East Pitts- 

 burgh, Pennsylvania, recently sent out a 32-page pamphlet de- 

 signed as "Circular No. 1094," devoted to the Westinghouse 

 Turbo-Alternators. The pamphlet is generously illustrated and 

 shows the turbine generators made by this company as in- 

 stalled in a great many of the leading power plants in the 

 United States. The interesting statement is made in the pamphlet 

 that during the past 17 years there has been a revolution in the 

 design of electric power plants. It continues : "The superior 

 economy of the turbo-generator unit, not only in steam con- 

 sumption, but in first cost, attendance and in maintenance as 

 well, and the reduction it has effected in general plant invest- 

 ment, in real estate, buildings and foundations, has practically 

 eliminated the large slow-moving reciprocating engine-driven sets 

 from the serious consideration of the modern power-plant en- 

 gineer and designer." 



The Manhattan Rubber Manufacturing Co., New York, has 

 recently issued a little six-page folder descriptive of its "Condor" 

 rubber belting, which the company states is equally good for 

 transmitting power, elevating or conveying material. In addi- 

 tion to a description of this belting, the folder gives a compre- 

 hensive price list of this belting in widths varying from one 

 to 60 inches, and in thicknesses from two to eight-ply. 



FACTORY VENTILATION AND HOW TO GET IT. 



A FEW years ago, manufacturers had an idea that there was 

 ** just so much work in a man and that they could get it 

 out of him regardless of what his surroundings were. But that 

 venerable theory has been exploded, for the manufacturer real- 

 izes now that to get the maximum amount of work out of his 

 employes, they must be surrounded by conditions that make it 

 possible for them to do their best. Plenty of light, the proper 

 temperature, and above all — good ventilation — are now prime 

 considerations with all factory owners. 



It sometimes happens, however, that while an employer's in- 

 tentions are good, his methods are not such as to effect the de- 

 sired results. For instance, in the matter of heat and ventila- 

 tion — air should not be blown on hot machines and presses to 

 cool them off. More heat is generated in that way; exactly on 

 the principle of the cold air box of the furnace. Heat should be 

 removed at the highest point possible; and where a fan is used 

 there should not be an open window nearby nor any leakage 

 where the currents can short-circuit. Gasoline fumes are best 

 removed at the floor. 



Many times in cold winter weather some factory superintend- 

 ent will be found trying to remove steam in some exceedingly 

 expensive way. The Autoforce System now used in many large 

 rubber factories, has been devised to eliminate the expense and 

 the danger of the power fan. The principle of the Autoforce 

 System is the simple one of working with rather than against 

 nature. The natural air currents are usually sufiicient for pur- 

 poses of ventilation and for carrying off excess heat. 



The saw-tooth roof gives the steady northern light, but the 

 heat in the peak is like the attic of a house. This is where an 

 Autoforce Air Pump must be used; nothing else will accomplish 

 the result. Heat should be utilized in winter, but should be made 

 to remove itself in summer, when it creates friction, curtails 

 efficiency of the help, and is dangerous. 



THE HAEDMAN COMPANY LOST BUT LITTLE. 



The loss at the fire in the factory of the Hardman Tire and 

 Rubber Co. at Belleville, New Jersey, which occurred in June 

 and was mentioned in our July issue, was not as great, we are 

 very glad to say, as was first reported. The fire broke out in 

 one end of the hard-rubber department and the entire loss of 

 stock and in damage to the building only amounted to some 

 $15,000 which was fully covered by insurance.
