Show million dollars. The Gnligher company com-pany will have the machines fabricated fabri-cated Immediately lu Chicago. Tho nurchase ef th!s largo amount of eqifipment Is not only a substantial recognition of tho merits of the Isbell type of vanners, of which the Gall-gher Gall-gher company Is the pole agent and i manufacturer, but it is a matter of ) congratulation that Salt Lake City can provide machines on the large scale conf eniplated. The lsball vsnner Is tho invention of J. F. Isbell. who has had wide experience ex-perience In the milling of pnrphvry ores. The last ten years have seen a great deal of activity in the develop-cient develop-cient of the percussion table nnd concentrating con-centrating machines of the table type, yet machines of the endless belt typo have heen neglected. The commer clallzing of the great low grade porphyry por-phyry deposits of Utah. Nevada and Arizona, which require fine griding and slime treatment, has given fresh stimulus lo the b.dt machines, and the profession realized that while the percussion table; has become Indispensable Indispen-sable for the treatment of sands, tho vanner still remain's without a reer for the treatment of slimes. The profession Is well acquainted with the Frue vanner, and tho Important Im-portant part It ha played in the treatment of ores. The fundamental principal of the Isbell machine Is substantially sub-stantially the same as in all vanuers, consisting of an endless rubber belt with a side shako, but It Is in its mechanical me-chanical arrangements and details of const ruction and its adaptability to modern mill conditions that differentiates differen-tiates it and has given It the preference prefer-ence in the Arizona mills now under construction. The essence of the Isbell design is a foundation girder of heavy channel chan-nel Irons, placed beneath tho center aud at right angles to tho length of I he machine. This girder carries a heavy transverse shaft, fastened to which by suitable brackets are two long leaf steel springs, one ou each side of the machine, the cxtremo ends of which support tho shaking tti'.nie. To this thaft nl'o Is sectnvl the hearings carrying the bead motion mo-tion with its shaft pulleys and eccentric eccen-tric and the side arms which carry the water box and the worm wheel belt traversing gear; this shaft there-fere there-fere becomes the axis to whbph tho entire mechanism is attached, and around which tho whole machine Is ceveloped. The nlceneps and utility of the d-plgn d-plgn Is at once apparent, for It makes the machine perfectly self-contained, the four snpiorting posts common to other types are eliminated, and the li .-spallation of tho machine reduced to the simple act of bolting the foundation foun-dation girder to the floor. The glr-cer glr-cer being also In line with tho vibrations vi-brations gives a rigidity to the ma ehne when In operation Impossible to of tain with the corner post r-onstru: tion. The Inclination Is changed hy tlp- Ing the whole machine with the transverse shaft ns the center of th-3 movement. A short oast iron stand set close to the head end and clamped to the projecting arms .hold the ma rline firmly to the require 1 grad The use of the long side steel b..af springs for carrying the shnkln? frame Is unique In vanner construction, construc-tion, and is a device for this purpose pur-pose Impossible to Improve upon. If combines great strength and positive-ness positive-ness with the necessary side flexibility flexibil-ity and refined leveling adjustments. At any given speed or stroke the mo-t'on mo-t'on is without tho slightest Jar or vibration and la truly horizontal, pn-fibllng pn-fibllng the heaviest loads lo be carried car-ried without any slopping over, and "andy or sloppy corners" are an impossibility im-possibility There aro no struts or 1 in and eye Joints to wear out or to -fiet out of place. In addition to sup-I sup-I porting the shaking frame they also serve, independent of the external bracing of the shaking frame, to maintain main-tain it perfectly square and In alignment, align-ment, no matter how uneven he tension ten-sion on one side of the belt may be. For adjustment ft simple set screw fnd lock nut at each back end ad-.1n?fs ad-.1n?fs the rear roller into perfect ao c.rd with the front on. Thes leaf springs are made of common untem-I untem-I ered quarter-Inch boiler plate, and altQr continuous service of over 13 months with the flr. machine ever built they show even under the most .icvere conditions a to length ot ttroke and speed, no signs of weak-d weak-d ss of crystallgatlon whatever. The Isbell pulp distributor consists ot two decks The upper one is slm-l slm-l ur to tho regular Jrue vanner dl-tilbutor dl-tilbutor and slopes toward the head roller; the lower one is Immedlatel.. tiudernoath and slopes the revers way. This lower deck Is composed of 16 wood slats 3 3-4 Inches wld by 20 inches long, spaced one-quarter of an inch apart and form 17 9lot. through which .the pulp falls. Th linderneath side of the deck so . formed . Is roughed with sawtootn. grooves over its entire surface, so that the pulp is distributed In in-rumerable in-rumerable drops over the entire Area of 12x72 inches, anj Is thereby do-.oslted do-.oslted on the belt without causing tho slightest disturbance of the pulu surface.
