THE INDIA RUBBER WORLD 



609 



INTRODUCING HARRY M. HOPE. 



M nT that he needs introduction to many of the American rub- 

 ' ber manufacturers, but more particularly touseacatchj cap- 

 tion; and this is really tin- important part, to say a word about 

 rubber mill engineers in general and Mr. Hope in particular. 



Time was when chemists were unknown in rubber mills. To- 

 day there arc as many chemists as superintendents, probably 

 mote History is repeating itself in respect to rubber mill en- 

 gineers. The field i- 

 there and it is be- 

 ing rapidly tilled, 

 and to the special 



advantage of the 

 rubber trade. The 

 important field for 

 the engineer is em- 

 bi a< • d in the eco- 

 nomic and engi- 

 neering features of 

 Hi. generation, dis- 

 tribution and appli- 

 cation of power. 

 Frequently great 

 -a\ ings can lie made 

 in the use of fuel 

 by comparatively 

 inexpensive changes 

 in the boiler plant 

 and the method of 

 tiring, based on an 

 accurate analysis of 

 existing condition- , , vk| . v M ,,,„., 



Even greater econ- 

 omic- can often he obtained by the application of power to 

 manufacturing equipment in such a manner a- to permit the 

 most efficient use of labor and the rapid conversion of raw 

 material into the finished product. All of this calls for special 

 training. That Mr. Mope outside of his ruhher mill work has 

 this in abundance i- proved by the following brief outline of 

 hi- activity in the engineering field : 



He was horn April 13. 1879. at Niles, Michigan, and attended 

 the excellent public school- of Muskegon. Michigan, N'orth- 

 western Universitj and Lewi- Institute of Technology. Chicago. 



Ill- early engineering experience was acquired with the 

 Muskegon Lighting and Traction Co., of Muskegon. Michigan 

 Me entered the employ of the Chicago Edison Co.'s testing labo- 

 rati m in 1902. and spent one year making power plant tests 

 and reports on manufacturing establishments and the power 

 plants of the company. 



In 1903 he was transferred to the engineering department of 

 the ( hicago Edison Co.. working as an engineer in connection 

 with the design of power stations and electrical transmission 

 and distributing system of the company. In 1904 he was ap- 

 pointed electrical engineer of the North Shore Electric Co.. in 

 charge of the design of power stations, sub-stations and electrical 

 tran-mission and distributing lines, and acted in an advisorj 

 capacity in relation to the construction and operation of the en- 

 tire power, generating and distributing system. 



In 1907 lie became associated with the engineering department 

 of the Stone & Webster Engineering Corporation, in Boston, 

 and for three years acted a- engineer in charge of the design of 

 power plants and electrical transmission and distributing sys- 

 tems. Here he made many investigations and reports relating 

 to the power systems of public utilities and industrial proper- 

 ties. In 1911 he was placed in charge of the engineering depart- 

 ment, as assistant to Frederic X. Bushnell. vice-president, He 

 continued in this capacity until March, 1915. when he resigned 

 to estahlish his own organization of power experts. 



PERSONAL MENTION. 

 I dward B. Aldrich has resigned as vice-president and treasurer 

 of the Intercontinental Rubber Co. and as officer of their allied 

 i i impanies. 



I i S, Miller, who for the past four years has been connected 

 with ill. ill - force of the Diamond Rubber Co., in the New 

 Orleans district, has severed his connection with that corn- 

 pain and announce- hi- inn niioti of taking a much m 

 rest, 1. ir the present. 



Arthur Jones, a director in the ruhher brokerage firm "i 

 William Symington & Co., ..i London. England, arrived recently 

 in Xew York from the Far I a-t en route to London. 



Miguel 1'. Shelley, formerly connected with J. Mar.pic - 



of the leading exporter- of Amazon product-, ..t Para, Brazil. 

 has recently arrived in New York. II, ,- | jn South 



American trade, as he was connected with it, in various ways — 

 chiefly at the port of I'ara — for 25 years. He is particularly 

 familiar with South American rubber producing. Mr. Shellej 

 expects t" remain in Xew- York ami connect himself with the 

 South American export and import tradi 



E. .1. Kane, of 50 Ann street, New York, ha- hern connected 

 with the ruhher business, in rather a unique way, for a great 

 many year-, lie deals exclusively in second-hand articles. He 

 Carrie- a great variety of hose in stock and makes a specialty 



of fire department hose of ever) sort. His stock consists entirely 



ot article- that have been used but which have been use 

 little as to entitle them to further service rather than to relega- 

 tion to the reclaiming work-. 



A RUBBER ADVERTISING MAN WINS A HANDSOME PRIZE. 



A year ago last spring an association of 40 American manu- 

 facturer- off, red cash prizes aggregating $3,000 for the best 

 idea- submitted which would help them in any department of 

 their work, cither manufacturing, selling or advertising. The 

 contest, which was open for a year, closed last May. The award- 

 have been made, and the second prize, amounting to $500, has 



been given to R \Y. \-hcroft, the advertising manager of the 

 Canadian Consolidated Rubber Co., Limited, of Montreal. 



THE INVENTOR AND THE PNEUMATIC TIRE. 



Iii commenting recently on the number of letters received 

 daily containing suggestions for the improvement of the pneu- 

 matic tire. L. C. Rockhill, manager of the automobile tire de- 

 partment of The Goodyear Tire & Rubber Co., of Akron, states 

 that the prospects are excellent that the present pneumatic tire 

 that we know will remain for an indefinite period superior to the 

 schemes for improving it. He state- that the company is able to 

 use about oik- in every 200 suggestions offered. 90 per cent, of 

 which aim to render the tire puncture proof, usually by means 

 of a metal tread or a metal -trip sel in the tire. He adds: 



"As a in. iiicr oi fact, puncture-proof qualities, in compari- 

 son with other qualities which arc- imperative, are a minor 

 point in tire construction and are usually obtained by sacri- 

 ficing some other desirable quality. ( >ur investigations show 

 thai on a basis of 100 per cent, for direct wear on a tire. 11 

 per cent, will represent expense caused by punctures." 



SUBSTITUTE FOR EBONITE. 



I'i \-ric Compositions. — W. Plinatus, British patent No. 12,142 

 (1913L A product resembling horn, ivory or ebonite is made by 

 mixing albumens, such as serum, m; oi casein, with an ester 

 of a polyvalent alcohol of the fatty acid -cries, such as the 

 acetins or other esters of glycerin or polyglycerin. Other sub- 

 stances, -uch as fats and oils, or sulphuretted oils, resins, pitches, 

 paraffins, camphor, cellulose derivatives, or caoutchouc may be 

 added in dissolved state or otherwise. The mixture may be 

 treated with hardening substances, such as aldehyde, tanning 

 substances or chromium compounds, and coagulable albumens 

 may he hardened by chemical or steam treatment, billing and 

 coloring substances may be added.
