NO. 1 OR SMALL CASE CRUSHER, HAND AND POWER 



2466 CRUSHER, Case. The Case Improved Laboratory Crusher is designed to meet 

 the constantly increasing demand for a strong Laboratory Ore 

 Crusher with greater capacity than any other similar Crusher. We 

 unhesitatingly recommend it as being the strongest, fastest and best 

 Laboratory Crusher ever built. 



The above cuts represent in detail the Combination Hand and Power Machine, 

 which has the essential features of strength and speed, and, at the same time, requires 

 the least power of any Crusher, for work accomplished, on the market. 



This Crusher is the most easily cleaned Crusher manufactured. It can be so thor- 

 oughly cleaned that there is no possibility of salting. The simple turning of a large 

 hand nut loosens the stationary jaw, which may be removed and brushed off. This 

 large hand nut serves a double purpose it is sufficiently large so that it gives great 

 leverage and the jaw does not work loose when the Crusher is in motion. The movable 

 jaw is provided with loop handle cast on top, by which the jaw is lifted out of the 

 socket for cleaning. 



Another special feature with reference to the jaws is that both are pivoted from a 

 center, so that when one end becomes worn it may be reversed and you receive double 

 wear from the Crusher plates. 



The Case Crusher is shipped with three replaceable shims or liners which fit be- 

 tween the stationary jaw and the Crusher frame. By inserting these shims, your prod- 

 uct may be ground to any fineness. 



This machine is lubricated by means of grease cups in place of the old method of 

 using oil, which means that it will run for days with very little attention. 



The capacity of the Crusher of this character depends on the nature of the product 

 to be crushed. This machine will take rock or soft substances 2 l / 2 " in diameter re- 

 ducing so that same will pass through a 10 mesh sieve or finer at the rate of from 50 to 

 150 pounds per hour. 



The shaft is 1^2" in diameter, driven by a 9" pulley with a 2^4" face, at from 450 to 

 500 revolutions per minute, and requires 1 H. P. for general use. Opening of jaws, 



All parts of this machine are made on jigs in exact duplicate, consequently replace- 

 ments can be had at minimum expense. In other words, the Case Crusher is a thor- 

 oughly standardized machine. 



Floor or bench space required for small size: 14j4"x21". Net weight: 140 Ibs. 

 Shipping weight: 165 Ibs. 



Kindly compare all of the above good Crusher features when in the market for a 

 Crusher and make no mistake.
