476 to form the first mixing. These mul- tiple jets of oxy-acetylene gas then enter a conical expansion chamber, forming a vortex, before they con- verge in a single passage leading to the flame end of the tip. This mixing of gases under equal pressure in- sures a neutral flame. The cutting tips are made in one piece of special bronze composition with high percentage of copper to withstand the heat of the cutting flame. The seats of the tip are flat, with annualar grooves coinciding with those in the head, the gas passages being drilled in the annular grooves or rings. The rings separate the gases. An outer protecting ridge prevents injury to the tip seat in rough handling. With the flat seat of the tip, sufficient play is given for lateral expansion of the torch head and tip under the locking nut without cracking or distorting the head. The flat seat is easily refaced with a hand burnishing tool, and new tips do not require “grinding”. The oxygen orifices pass directly through the tip, practically in parallel. The acetylene drilling enters the oxygen passage at an angle of 30 degrees from the outer ring, and is accessible for cleaning. New Lake Marine Office The Babcock & Wilcox Co., 85 Lib- erty street, New York, manufacturer of water-tube boilers for land and marine service, has opened a marine office in the Guardian building, Cleveland, where an office for land boilers was already located. The marine representative will be John Coleman, who has been con- MARINE REVIEW Lock Grip Stockless Anchor Im proves Old Style The stockless anchor possesses decided advantages over the old style or stock type anchor, but a valuable feature pos- sessed by the old fashioned type is there- by sacrificed. Un the latter, ‘the weight of the shank, stock and chain helps to hold the point of the fluke in contact with the ground. In the stockless type as it is necessary to pivot the shank to the flukes, the weight of the shank and chain does not help to hold the point of the flukes in contact with the ground. October, 1921 lock the shank of the stockless anchor to the flukes when the anchor was in holding position and automatically re- lease the flukes when the shank was in a vertical position. The accompanying illustrations a comparative test made with a 4000- pound stockless anchor as it is common- ly designed and a 3000-pound anchor equipped with a locking device. The anchor with the locking device began to bury itself before it had been dragged more than three feet, whereas the anchor without the device was dragged 35 feet on hard ground without showing any signs of digging in. It is pointed out that the device will not interfere with the freedom of ro- tation of the flukes in any position. When the shank is raised to the vertical position the pawl head is carried out of the de- pression on the anchor while the counter- weight prevents it from dropping back into the depression until the anchor is again in holding position and the shank lowered to the horizontal. The flukes are, therefore, free to fall, as at present, either way that the direction of the pull demands. Whenever the anchor is brought up to the ship the locking device is automatically disengaged and the flukes are free fo fotate as at present. “The device is designed so that the pawls will not interfere with the stowing of the anchor in the hawse-pipe. The device has been approved by the American Bu- reau of Shipping and Lloyd’s Register of Shipping. This device was originated by A. Trevor Jones, American Steel Foundries, Chicago. show THE UPPER ILLUSTRATION IS A STOCKLESS ANCHOR EQUIPPED WITH A LOCK GRIP WHILE THE LOWER VIEWS SHOW A COMPARATIVE TEST BETWEEN TWO ANCHORS nected with the Babcock & Wilcox Co. for more than 20 years, most of that time being superintendent of the marine erection department. Before coming with the boiler company, Mr. Coleman was for a number of years an engineer on lake steamers and has a wide acquain- tance in that territory. The selection of Mr. Coleman was made to put the office in charge of an expert thoroughly familiar with boiler problems and with lake conditions in particular. As a result, the stockless anchor does not take hold comparatively quickly. The purpose of the device, shown in the ac- companying illustration is to provide the stockless anchor with what might be termed the hook action possessed by the older type. This anchor is manufac- tured by the American Steel Found- ries, Chicago. To accomplish this, a device was in- corporated which would automatically Coal Trimmer Distributes Fuel in Ship Hold For storing coal in portions of the hold of a ship which are inaccessible to gravity flow, a mechanical coal trim- mer recently has been developed and is so devised that this result may be se- cured as necessity demands. The equip- ment consists principally of a rotating cowl and a pivoted frame carrying the
