the following description taken in connection Cooperating with the casing 4 and with the with the accompanying drawings forming a barrel heads 38'and 39 and forming the movpart thereof, in which able segment is the endless conveyor 5 suit- ,q Fig. 1 is a vertical sectio'n through a tumably supported upon three pairs of sprockets bling mill; and p 43, 44 and 45, these sprockets being supported Fig. 2 is a section on the line 2-2 of Fig. 1. on suitable shafts, two sprockets on each In the following description and in the shaft. Secured to the casing end walls 6 and claims parts will be identified by specific 7, one on each side, are track members 46 and 50 names for convenience, but theyare intend- 47 for supporting the endless chain at the 100 may be better understood by referring to for a purpose hereinafter described.
point where the articles to be treated exert their weight.
The movable segment or traveling conveyor 5 is made up of chains 52, 53, one on each side, running on the sprockets 43, 44, on each side. These chains are made up of a series of links 54 connected by pins 55 having rollers 56 thereon. Each link 54 has a lateral extension 57 on which seats a pair of angle irons or aprons 58 extending the width of the conveyor from one chain to the other. Each extension 57 has a diagonal sealingn iange 59 riding in abrasive from the tumbling chamber. The angle irons 58 are disposed close together as indicated-in Fig. 1 so that no abrasive can pass through the conveyor. For driving the conveyor a spur gear 85 is mounted upon the shaft 84 which supports the lower sprockets- 44. Drive gear 85 may be driven by a suitable reversible motor (not'shown).
It will be n oted that the chains 52, 53 are voutside of the blasting chamber and are therefore protected from the direct force of the blasting, while only exposed to the blasting are the angle irons 58 and the liners 41 on the barrel heads, all of which maybe replaced when worn. The chain rollers 56 ride on tracks 46,l 47 thereby insuring proper support for the weight of the articles being treated, which may be considerable.
The casing is provided with a composite door 13 comprising an upper section 16 and a lower section 17, this door closing the charge opening. The sections" are suitably pivoted together bhinges 18 and the upper section is suitably pivoted to the `casing by a Vhinge 21. The lower door section 17 carries suitable nozzle holders 29 for supporting nozzles (not shown) which direct abrasivesuch as' sand on the4 articles tobe treated.
a itting 105l is provided comprising, a
l branch 106 and a branch 108. The branch 106 is illustrated as seating in a groove 107 in hub 36 to provide a sealing arrangement at this point. An exhaust fan or other suclhinge 110 is overcome and the gate 109 opens,
allowing the abrasive toy fall upon inclined screenV 112 and thence into pressure tank 113. Y It will be noted from Fig. 1 that the conveyor sags .at its lower part between sprockets 43 andq 44, and that it is taut at other places; Thus the conveyor is self-tightening, the part fitting againsttliefbarrel heads 38 and 39, being kept tight against these heads by the weight of the parts of the conveyor Vbea groove 42 to prevent escape of the' nient of the conveyor causes For removing abrasive and dust from the mill l mOVeS.
Touse the apparatus the door 13 is' opened and the articles to be treated are placed 1n the pocketformed by the movable conveyor 5. The door is then closed to the position shown in Fig. 1 and the driving motor started to rotate the gear 85 in such direction as tocause the conveyorto move in the direction indicated by the arrow the articles upwardly. It will be seen that as these articles are carried upwardly they will slide and tumble down Lcontinuously as the conveyor moves, exposing all sides thereof to the action of the sand blast coming from the nozzles (not shown) in the nozzle holders 29. f
The particles removed from the surface of the articles and the spent abrasive collects upon the conveyor and the draft of air Xin Fig. 1, carrying through the tumbling chamber and movethe abrasive to drift against the head 38. the conveyor againstthe head 38 causes rotation thereof and the abrasive passing through the openings 102 is carried by the vanes 103 and' delivered out through the hollow shaft 36 together with dust into the fitting 105.
lThe dust is carried out through branch 108 while the abrasive falls into the bottomof.
the fitting. The abrasive is delivered to the s creen 112 by the action above described and this screendiscards all coarse particles removed from the articles treated, allowing the abrasive to p ass into' pressure tank 113A where it is picked lup and directed tothenozzle holders 29. The abrasive thereby travels in aclosed path and is-used over and over again.V The air passes" into the mill principally through the opening in shaft 37 and through the vents 12 in the top of thecasing.
After-the articles have been treated suiiciently, if desired the abrasive nozzles are shut off first and the conveyor allowed to run toremoveall loose abrasive from the mill. The suction draft is then shut off and the door 13 opened.' and the driving motor which` drives gear 85 is reversed. This reverses the motion of the'conveyor 5 andquickly carries the articles out through charge opening onto the ioor or receptacle waiting for them.
Thus it will be seen that the above described tumbling rnill is rugged in construction, simple and eicient in operation and occupies but small space. The particular construction of movable conveyor provides,
most useful arrangement in which the worn 'parts may be easily replaced. Theworking The friction of treated. The utilization of a rotating head to convey the abrasive from the machine assists in making a compact construction. Furthermore the vents 12 provide for additionaland necessary air flow into themachine increasing that which is drawn in through the hollow shaft 37 to reduce the resistance to the removal of material through trunnion 36.
This application is a continuation in part of application, Serial N o. 298,194, filed August 8, 1928.
