frrlech.nical Tail Sawyer Invented Lumbir Production One o[ Sn ]or Sawmills ltems Reflecting Business Activity

A mechanical tail sawyer for the sawmill, known as the sawing rig, is one of the latest contributions for meeting economical production methods. It is the invention of 'Charles J. Pettibone, general manager of the Edward Hines ^Western Pine Company at Hines, Ore. Three band sarvs in the Hines' sawmill have been in operation for over a year [vith the mechanical tail sawyer.

The sarving rig pulls lumber from the log carriage and illaces it in position upon the lumber conveyor; it keeps the prea behind the saw clear of wood fragments thrown oft by the saw, and it provides a method for automatically raisiing and lowering the guide on the band. The new invention performs all the duties of the man stationed behind the head saw.

' Two methods are employed for removing the boards from the carriage. First, an inclined guide extending 2O feet along the lumber conveyor dire'cts the lower side of the board away from the carriage. The board is then caught by a series of screw live rolls which pull it into a flat position on the conveyor ready for transportation to other parts of the mill. The second method substitutes a corrugated roller for the inclined guide. The roller is built in three sectiuns and rotates away from the carriage, thus propelling the board immediately upon the live rolls. The screw. tolls are also used here but it is necessary to have but two as compared to five or six required for the satisfactory bperation of the inclined guide.

Located opposite the guides on the conveyor is an inclined shield whi,ch prcvents short boards or slabs from trodging crosswise on the conveyor. The shield also keeps wood fragmehts from falling on the ground. Occupying .the position on the conveyor of the first two live rolls is an Lrrat"r. slat bed which serves as the waste disposing feature of the sawing rig. This waste may be removed by another conveyor to be burned or ground up for fuel.

. The saw guide is raised automatically by an electric -3witch on the carriage. This switch is operated by the foot pedal controlling the dogs which hold the logs on the carriage. Current is supplied the switch from an overhead trolley wire insulated in the center so that the wire is electrified opposite or past the saw but not in the region of the log deck. The operation of the dogs to receive a new log or ,turn the one on the carriage does not affect the switch. It is only when the dogs are raised to release the last board drom the carriage that the circuit is established thereby perileitting the saw guide to rise to its maximum height. To prevent injury to the sawing apparatus limit switches have been installed to break the circuit automatically at its upper and lower extremes of travel'

The sawyer has been assigned the duty of lowering the saw guide. A switch is located on the end of the nigger .level and.the sawybr may arbitrarily lower'.the guide to any desiredlosition by'pressing this switch. Another switch is i"st'jliett near the sawyer to raise the saw gultle in case he tlrops the device too low for the log to clear or if some Fmergency arises.. .. ---.:

Washington, D. C.-;Lumber production, steel mill activity, electric power, freight car loadings, cotton forwardings and automobile production are the six items reflective of national industrial activity which now make up the Weekly Business Index of the New York Times, published each week in the business section of the Sunday issue. These indexes are based on estimated normal (100) and are adjusted for seasonal variation. The lumber production index was initiated through the cooperation of the Nati.onal Lumber Manufacturers Association, the Annalist and the Division of Statistics of the Federal Reserve Board.

A chart of lumber production f.rom 1929 to the current week, graphing the indexes, is published each Friday, also in the Times. The chart is accompanied by a brief statement based on data from the National Lumber Manufacturers Association covering the significant factors in the lumber movement of the preceding week.

Charles F. Grim

Charles F. Grim, pioneer retail lumberman and president of the Ganahl-Grim Lumber Co. of Anaheim, Calif., died at his home on Wednesday evening, July 12. He had been a resident of Anaheim f.or 32 years and was prominent in the city's business and civic affairs. Ife was 75 years old.

Born in Morrow, Ohio, on March 10, 1858, he moved to California in 1887, locating at Santa Ana. In 1901 Mr. Grim moved to Anaheim where he was employed as manager of the Griffith Lumber Co. yard. In 1904 he established the C. Ganahl Lumber Co. yard at Anaheim, now known as the Ganahl-Grim Lumber Co., of which concern he was president at the time of his death.

Mr. Grim took an active interest in lumber affairs and was the first president of the Orange County Lumbermen's Club, which position he held for ten years. He was a director of the Savings, Building and Loan Association of Anaheim, a director of The Sanitarium, and for over ten years served on the advisory boards of the old Golden State Bank, and Anaheim branches of the Bank of Italy and Bank of America.

He is survived by his wife, Mrs. Agnes Grim; two daughters, Mrs. Mary Grim Heying of Anaheim and Mrs. Ruth Grim Minor of Burlingame, Calif., and six grandchildren. Funeral services were held Saturday morning, July 15, at Anaheim.

Sacramento Yard Has Fire

Fire, believed to have been set by "firebugs", destr.oyed the planing mill of Burnett & Son, Sacramento, July 6. The loss was covered by insurance.

The accuracy of the invention is worthy of consideration as eve.ry board cut is removed from the carriage with mechanical precision, and it also offers benefits over the old lneth'ods from a standpoint of safety. All rights to the phtent,{rave been turned over by Mr. Pettibone to the Edward Hines Western Pine Cqmpany of Chicago.
