A further object is to provide a self-sealing swivel joint for the high pressure water line, a feature of this joint being that it compensates for wear on the packing material without hand adjustment and constantly assumes the minimum degree of resistance to turning consistent with the pressure against which it is required to maintain a seal.A further object is to provide the discharge nozzle retaining sleeve with means for cleaning the thread of the gun body when the two are screwed together.A further object is to provide a method and apparatus for cleaning by abrasion in which the abrasive, after a cleaning operation,<a href="http://www.sellercrusher.com/solutions/mini-milling-machine.html">Mini Milling Machine</a> may be collected, classified, and recirculated through the machine.Another object of my invention is to provide a process and apparatus for cutting coherent solids which reclaims and utilizes particles cut from the solid as abrading material.
A further object is to provide a feeder in connection with the collecting means for the used sand or particles, and in which a suction is created by the gun for lifting the sand from the collecting means.A further object is to provide means within the feeder for keeping the sand and water in a mobile condition and to provide easy starting of the gun after a period of inoperation.With the above and other objects in view the invention resides in the method together with the combination and arrangement of parts as hereinafter set forth,<a href="http://www.sellercrusher.com/solutions/stone-crusher-in-quarry.html">Stone Crusher In Quarry</a> shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention. In the drawings: Fig. 1 is a vertical longitudinal sectional view of the gun; Fig. 2 is a vertical longitudinal sectional view of the swivel joint between the inlet water hose and the gun; Fig. 3 is a vertical longitudinal sectional view of the feeder; Fig. 4 is a sectional view of the feeder cut along the line of 4-4 of Fig. 3; Fig. 5 is a vertical longitudinal sectional view through the platform, and sand classifier, showing the feeder in the tank, and the gun and water supply connected therewith; and Fig. 6 is a sectional view of the gun cut along the line 6-6 of Fig. 1.
Referring to the drawings, and particularly to Fig. 1, which shows the gun as a whole, the gun comprises an elongated casing I fitted with a hand grip 2 at the forward end and an arm rest 3 at the rear. Inside this casing is a tube 4 made up of the axially aligned sections 5, 6, 1, 8, and 29. Inside the tube 4 are arranged three tandem nozzles, 9, 10, and II, in spaced relationship to each other so that a chamber 12 is &5 provided inside the tube 4 between the rear nozzle II and the intermediate nozzle 10 and another chamber 13 is provided between the intermediate nozzle 10 and the front nozzle 9. The opening in the intermediate nozzle 10 is larger than that in the rear nozzle I, but smaller than the opening in the front nozzle 9.
