Types of Belt Lacing 



A writei' iu the Cunailian Lumbprman says 

 that he has in use four diffori'iit kinds of Ijelt 

 laclna. which can be placed iu three classes. 

 'I'he fii'st comprises belts working where damp 

 conditions prevail, the second, belts working in 

 a temperature of 120 degrees and over, and the 

 tliird, belts working in dry places and in normal 

 (emperature. The writer considers that rubber 

 belts with rawhide lacing are best adapted lo 

 the first class, and states that he has found 

 iron and steel clamps absolutely worthless under 

 those conditions. Belt lacing machines using 

 wire also cause considerable trouble, especially 

 where the wire pierces the belt, rot setting in. 

 necessitating cutting out a piece .nfter a short 

 time. 



'rtie correspondent says that he has a num- 

 ber of belts working in a temperature of 150 to 

 200 degrees, and has tried lacing with rawhide 

 clamps, and with machine spiral belt lacing. 

 The latter proved to be the best for leather Ijelts, 

 as the rawhide lacing soon dries up and lireaks, 

 while clamps burn and tear the belt. lie found 

 a canvas belt of good make to produce better re 

 suits under such conditions of temperature, but 

 with this tyjje of belt, rawhide lacing was neces- 

 sary as the spiral lacing tended to unweave the 

 belting. i)Ulling out iu time and producing a 

 ragged edge. 



He mentions that luider ordinary conditions 

 leather belts laced with spiral lacing produce the 

 best results and that by sewing on the machine 

 and sinking the lacing in the belt a perfectly 

 level smooth running joint is obtained, and a 

 smaller pulley can be used. 



Speaking further of canvas woven belts in 

 damp places, he stated that metallic lacing is 

 preferable, the best spacing being three-quarters 

 of an inch from the joint, and for leather belts 

 from ten to twenty-tour inches. On one opera- 

 tion a twenty-inch belt driving 120 kilow^att 

 generator, the driving pulley being 104 inches in 

 diameter, operates at 1-4 revolutions to the min- 

 ute. The driven wheel is 20 inches in diameter, 

 and the shafts are 12 feet on centers. This ne- 

 <i'ssitates a very taut belt, yet the metallic lac- 

 ing has been in active use for two years without 

 any se"ions trmilile. 



Long Logging-Flume in Mexico 

 The Pacific Lumber Company, a Philadelphia 

 syndicate with large timber holdings in the 

 -state of ^lichoacan, Mexico, is engaged in the 

 c onstruction of the largest logging flume in that 

 countr.v. When completed the flume will be 

 twenty-six miles in length, and will run from 

 the woods operatiou in the Coalcoman district 

 to a shipping point on the Pacific coast, where 

 a modern mill will l>e erected for the manufac- 

 ture of the 2.000.000.000 feet of pine, mahogany, 

 cedar and other woods owned l>y the company. 

 A general awakening among lumber interests 

 in the vicinity of the city of Durango is the 

 lesult of the beginning of work on the 100-mile 

 extension which the National Railroad at Mexico 

 is running into the 500,000 acres of timherland 

 southwest of that city. American capital has 

 receutly been invested in several large holdings 

 iu this zone, whicli will be operated when they 

 are in touch with railroad facilities. Similar 

 activity along the western slope of the Sierra 

 Madre range is prompted by the construction 

 of the Southern Pacific Railroad of Mexico 

 down the coast. The timberlands in this sec- 

 tion will be exploited b.v means of tram-lines 

 acting as spurs for the Southern Pacific. 



Red Gum Firm on the British Market 



A conununication from London states that the 

 appreciation in the price of satin walnut or red 

 gum is well maintained. Consumption in the. 

 United Kingdom has increased in the last month 

 and arrivals are considerably lighter, espeeiall.v 

 witli the well-figured l)oards of good quality. 



Stray parcels are offered from time to time on 

 consignment, and described as prime, which very 

 seldom come up to this grade. In any case each 



carload is sold on its merits, and therefore the 

 prices of strictly prime and medium boards are 

 not affected in the least by the miscellaneous 

 parcels. The shortage of supply has rendered it 

 difficult to contract with relialile shippers, a con- 

 dition which will likely continue until fall. In- 

 dications are that the advance in price will con- 

 tinue during the next few months, owing to tlie 

 shortage, and also on account of the increased 

 demand from the continent. 



still it will require considerably more wood than- 

 was formerly consumed for this purpose. Any 

 kind of lumber is suitable. A company has beea 

 formed to put the thing on the market, and 

 they have already booked orders large enough to 

 warrant the purchase of proper machinery. 



•Zimmerman's Instantaneous Glue Converter 



Below is a brief description of the operation 

 of the instantaneous glue filtering converter 

 which has already obtained a wide popularity 

 anions manufacturers of lumber : 



<;iue is soaked in the glue converting vessel, 

 v-hich fits closely in a soaking tank. The con- 

 \Hrting vessel with soaked glue is then lifted 

 from the soaking tank into the melting appara- 

 tus. Steam is then turned on and the glue 

 immediately liquefies, flows from the converting 

 vessel into the catch basin, passes through the 

 brass filter removably seated in the catch basin, 

 and flows on out into gluing machine or bucket. 

 When steam is turned off the flow of glue stops 

 and the glue left in the converting vessel re- 

 mains there iu cold jelly form, ready to be 

 liquefied when steam is again turned on. The 

 temperature never varies, glue is fresh and 

 uniform, and the quality is fully preserved. 



ZIMMKKMAX-S INSTAXTANEOUS CUE 

 CONVERTER. 



Without boiling or stirring, this :ipi)aratus 

 will deliver freshly filtered glue as it may be 

 needed : occupying only a few feet of floor 

 space, it will melt glue at the rate of one pound 

 A minute, equal to about 125 gallons of Ibjiiid 

 glue, or 500 pounds of dry glue, per day. The 

 glue always remains cold, hence there is no 

 di terioration in strength and evaporation is 

 impossible. The glue is ready for immediate 

 use as It flows from the apparatus, and. as 

 stated, simply turning on and off the steam 

 starts and stops the supply as desired. 

 There is no digging out glue from soak- 

 ing buckets, as they are done away with 

 entirely and glue is soaked and melted right in 

 the converter. There is no mess and dirt, and 

 crusty, burnt glue never accumulates on the 

 apparatus. All glue melts away perfectly clean 

 and there is no possibility of clogging at drain 

 pipe. This device is manufactured by the In- 

 stantaneous Glue Converter Co., Cincinnati. (). 



A New Grape Barrel 



An innovation in grape barrel construction is 

 reported as the invention of a man in Almeria, 

 Spain, the name of whom is recorded with the 

 Bureau of Manufactures at Washington. In- 

 stead of being all in one section, as is the case 

 with the old style barrels, thus subjecting the 

 entire mass of grapes to the liability of spoilage, 

 there are four compartments, each allowing of 

 proper aeration and being made of solid wood. 



While the invention is a machine-made product, 

 allowing of but little waste in its construction. 



Remarkable Growth of a Pacific Soaport 

 Town 



I'ntil recent .years the name San Pedro w>is 

 hardly known, even on the Pacific coast, and 

 while today it is but little known east f)f the 

 Mississippi, it is one of the biggest lumber- 

 receiving ports of the country. This town is- 

 located 105 miles southeast of Santa Barbara, 

 and according to the custom house figures, last 

 year's receipts showed a total of 500,000.000 

 board feet of lumber, largely redwood, Douglas 

 fir and yellow pine from the forests of the 

 Northwest. This is considerably more than the 

 total amount of lumber received for the year 

 11)09, by water, in Chicago. 



The lumber business of the Northwest has- 

 been fighting against great odds, in inadequate 

 transportation facilities. They have there beea- 

 striving to cut the trees in accordance with 

 l<lans which- will perpetuate the forest growth. 

 I'Ut the high cost of transportation has lim- 

 ited sales to a great extent. With the opening 

 of the Panama canal the industry should be 

 revolutionized. The conditions now prevailing,, 

 which limit the marketable timber to highest 

 grades, will be eliminated, and a far-sighted and 

 practical polic.v can be carried out. 



Reports from English Markets 



Such British timber merchants as IMwarcT 

 Challoner & Co., Farnsworth & Jardine, and .lobn 

 II. Burrell & Co., report that the receipts from 

 North American ports, on the Liverpool market, 

 were, for June. 19.240 tons compared witit 

 2;i.243 tons during .June of last year. The ar- 

 rival of oak logs from this country consisted of 

 (1.000 cubic feet, while the consumption was but 

 4.000 cubic feet. Moderate stocks and firm, 

 prices prevail. Arrivals and deliveries of wagou 

 planks have been fair and about equal in vol- 

 ume. The market is long on lower grades. 



These companies report light stocks and firm 

 prices for elm. of which the consumption has 

 been 1.000 cubic feet and the import nil. 



A moderate consumption and importation of 

 ash has prevailed, and the market is conse- 

 quently rendered slow with poor prices and 

 abundant stocks. 



The demand for American walnut has been 

 \cry steady during the month and very fail- 

 prices prevail for logs. Sawed stock, however, 

 still exceeds the demand and consequently unsat- 

 isfactory prices prevail. 



A continued increase in the demand for gum- 

 is evident, high grade stock especially being 

 a good seller. 



Yellow poplar logs have been imported in large 

 quantities during the fnonth. As in this country 

 the high grade stock is a good seller and com- 

 mands a good price, but low grades are slow. 



Birch logs have arrived in moderate quan- 

 tities and have sold fairly well. Firm prices 

 Ijrevail, caused by a light stock and a steady 

 market. About the same can be said of manufac- 

 tured stock, of which but a moderate amount has 

 been received. 



The Challoner Company reports having re- 

 ceived from various quarters 2.IJ0ti logs of differ- 

 ent varieties of mahogany. As usual, logs of 

 good quality are hard to secure and sell readily 

 at an excellent figure, but crooked, inferior 

 logs are but poor sellers.
