Show A HOME production heusser assay and anal analytical balance with multiple weight attachment communicated this balance was designed in response to a general demand for a time and labor saving weighing instrument by its use the tedious task of picking up and placing small weights upon the balance pans and arresting the balance each time for this purpose is eliminated with reference to the accompanying illustration the pan hanger on the right side carries a perforated plate or grid back of this pan hanger a short column is ly mounted upon the base plate carrying nine movable levers the front end of each or of these levers carries an upright conically tipped staff which moves centrally and vertically thorough the perforations of the grid the levers are operated from the outside by means of depressible push keys arranged similarly toa typewriter keyboard and located in front of the balance the illustration shows eight levers in their uppermost position with the weights at rest and one lever in its lowermost position with its weight deposited upon the grid the weights are in the form of discs each disc having a central perforation at rest they are supported by means of the conically tipped staffs which extend partly into the perforations when in use they are deposited in countersunk holes in the grid these weights may be deposited and again picked up independently of each other and while the balance beam is free to swing by simply pushing the depressible keys up and down the value of each weight is plainly marked upon an index inde plate placed above the I 1 key board and the possibility of making mistakes is positively excluded the capacity of the weights is mill mili grams for assay balance and is divided as f follows 1 2 3 5 10 20 30 50 and milligrams for extremely delicate where the 12 milligram rider is used the capacity is only milligrams since the greater part of buttons will come within this range the handling of weights with tweezers is almost entirely eliminated these balances will save 50 per cent of the time consumed in weighing with an ordinary balance and for assay offices where considerable weighing must be done this may amount to a great deal for analytical balances tire the weights are ten times heavier or 2220 milligrams in all these balances are manufactured by wil 4 ka L 4 n assay balance with multiple weight attachment frid heusser balance maker board of trade building salt lake city utah |
