6 Claims. (cl; 51-11) This invention relates to a sand blast tool and is shown as an annular passage and receives one more particularly to a sand blast tool adapted to end of a'tubular member 20. be received in a bore having laterally extending "The one end of the tubular member 23 is propassages and to provide a lateral discharge nozzle vided with an annular flange 22 which is received for directing the blast into the laterally extending against the outer surface of the headerlil and passages of the bore. is' held in rotatable position thereon by a collar .Heretofore, it has been the general practice in 24 having screw thread engagement withtheend sand blasting comparatively small, cored passages, of the header 10. The tubular member 29 is proand particularly tortuous passages, to divert the jectedlongitudinally beyond the end 'of' the blastof sand by a correspondinglyshaped pasl0 header [land is adapted to be inserted in a lonsage in the sand blast tool causing the sand to imgitudinally extending bore 26 of a workpiece 28, pinge on the wall of the sand blast conduit. This such as a cored casting having transversely ex-t causes a rapid wearing away of the tool conduit t ndin 'p ages 30. I and repeated replacement. When it is desired to remove core sand, scale It is, therefore, an object of this invention to or the like from passages extending at an angle provide a sand blast nozzle having a fluid pressure to another passage through which the sand blast conduit which delivers the pressure through a tool is inserted, it is necessary to conduct the tortuous passage before the sand is mixedwith b ast, first n a direction corresponding to th the fluid pressure so that there is no diversion direction of the first p ss and then divert e of sand under pressure. direction of blast so that it is directed into the Another object ofthe invention is to provide a lateral passages. Heretofore, this has been done header member having a fluid pressure chamber by di ti t e St e O mixed fluid p s e and a sand chamber with separate passages exand sand in a tortuous path. This causes an tending longitudinally throughamember adapted abrasive action on the diverting wall with the to be received in a cored opening and havin a result that the parts of the passages are quickly laterally extending discharge passage for the fluid worn and must be rep pressure communicating with the longitudinally y y improved construction I maintain a extending sand passage. separation of fluid pressure and sand until the A further object of the invention is to provide fluid pressure has been diverted into the required a header having a fluid pressure chamber and a 30 direction after which the sand is admitted to the separated sand chamber and a rotatable, tubular fluid Pressure Thus the Sand flees not member provided with separate passages c mimpinge on the walls of the conducting conduits. municating respectively with the fluid pressure The end of the tubular member 26 adjacent chamber and the sand chamber. the header I0 is provided with an annular sand Other objects and advantages of the invention passage 32 surrounding t e p it which rms will be more fully understood from the following a'fluid pr ss e pass A member i a description taken in connection with the accoming a y n l Outer end r n substantially panying drawing in which; the diameter of the passage 32, has one side there- Fig. 1 is a longitudinal sectional view through of cut away diagonal. e fo ing a flat my improved sand blast tool Showing the Same 40 face 38 for directing the sand in the passage to ceived in a cored passage having laterally extendga i i gg g gpz gifg g i fig 2 3 5"; 222

A replaceable wear member 52 is fitted in the open end of the passage 50. By this arrangement of parts the sand is fed by gravity into the passage 50 where it is picked up by the diverted fluid pressure Withing 50 of the nozzle 44 may beqrotated to apply a sand blast to all portions of passages 30'. The collar 52 also serves as a stop to limit the depth at which the nozzle is insertedinthe bore 26;
