Application filed septembcr 12,- 1921. Serial N0.v 500,193.

Our invention relates to'means for vibrating objects for the purpose of removal of sand, dirt, or other matter adhering toboXes, foundry flasks, and the like. A

. The object of our invention is an efficientmeansfor vibrating objects for quickly and i thoroughly loosening and removing sand, dirt, or other matter which adheres to boxes, foundry flasks, and the like.

Infoundry flasks for instance, itis custommy to loosen the sand, which adheres to the A walls of .theflasks after a mold iscast,by

manual poundingon the flask with a mallet and labor, but also. causes the flasks tobe broken quite frequently by carelessworkmen.

To overcome these objections, the present invention provides an apparatus whereby' vibrations are created in the. object to be cleaned, which vibrations are sufficiently sharp and rapidto not only loosen but also remove or eject the adherent matter, thereby reducing the time required to vibrate the object vand eliminating the time required for scraping and cleaning.- With the present invention, in most cases, this cleaning or ej ect-- ing is done, or'canbe done'byhaving the vibrators working while the object is being raised or otherwise suspended, thereby further saving time. p A.mechanismto accomplish the above is illustrated in the accompanying drawingas an exemplificationand the apparatus so shown will 'be describ'ed in detail in this specification. i

' Various changes and modifications may be made in the apparatus"without departing from the spirit of this invention and without V sacrificing any of the advantages contained in the appende'dcl'aims; A v i v In the accompanying drawing, Fig; '1 is a general perspective view of 'a' hook mechani'smprovided with means for engaging a foundry flask and withmeans forcreatin'g vibrations therein FigJZis'a section on line 2 ofFig."4"; Fig.[3, is a section on line 3 of" i Fig, 4; Fig, .t'is a centrallongitudinal sec -justecl position by the nuts 201:

tion, one larger scale, of the vibrator mechanism; and Fig. 5 is a partial View showi'nga modification of the hook legs and vibrator mounting. i i v i 1 Similar reference characters refer to similar parts throughout the views; 1 I A. Theapparatus shown'in the drawing'jconsists, mainly, of the hook mechanism A, and the vibrators B, supporting the foundry flask C.

The hook mechanism A has the bale 10 to which the loop 11 is secured, and also hasthe preferably 'roundedat the top as shown, to

permit the legs to rock on the bale upon which the legs aresuspended,andalso has the 14 and 15 and thehook end 16.

lugs

These logs are suspended from the bale by distance from he legs to permit'the same to, rock on the bale. 1

legs .12 each of which has the opening 13,

The vibrators B, presently describediin 7 detail, abut flrrnlyagainst the lugs 14 and,

are held to the legs by the screws 18; The taper'keys 19 are interposed between the'bottom of the vibrators andthe lugs 15 and are adapted to be adjusted to take iup wear or lost motion and arelocked in ad;

The-plates21 hook over the lugs 14 and are provided to re-inforceVt'he.legs- 12 at thepoint where; the vibrations are created and also to, holdthe keys 19 imposition -s ide-- The pipe 22 withthe valve 23 and the ma pipe 24 is secured tothe bale by the'clips 25 and preferably has a hose connectionwith the source" of fluid pressure and also hasthe 3, and 4, c'onsists of the'cylinder 529whichis V top. This cylinder also has the inlet open? "ing 31, open at the top' only and threaded provided with main bore, open at the b'ottom I 1 andv terminating into the: opening 30 atzthe there for the inlet pipe 28, and alsohas the a inlet ports 32 and 33'open'ing into'the open:. i'ng 31. This cylinderalso "has two sets'of exhaust portsj34 @0135, each setconsisting of eight holes; This cylinderalso has threadFI ed -,o 'penings one side -for the] screws-1s J and in thebottom for the screws 36 which hold the cap 3'7 on the cylinder.

Inside of the main bore of the cylinder is the sleeve 38 whichis provided with inlet and exhaust ports corresponding to the ports 32, 33, 34, and 35.

The anvil block 39 is driven into the opening 30 and has the flange 40 to present a large bearing surface against the material of the cylinder and also has the anvil surface 41.

Thecap 37 is, preferably, centered in the main bore of the eylinder by the projection 42 andhas the outer flat surface 43 against which the key'19 rests and is held to the cylinder by the screws 36. This cap alsohas the'central opening 45 into which the anvil block 46 is driven.

The anvil block iti has the flange 47 to present a large bearing surface against the material of the cap, and also has the anvil surface 48 The openings and 45 permit of ready removal of the anvilblocks 39 and 46 when it is necessary to remove them for any purpose.

Inside of the sleeve 38 is the plunger 49 which-has the anvil'blocks 50 and 51, similar to the anvil blocks 39 and 4:6, driven into the ends thereof, and also has the grooves 52 and 53, and the port holes 54 and 55 be- 7 tween the grooves and the outer ends of the plunger, respectively, as shown.

T lic plun er is, preferably, hardened as a whole andt 1e anvilblocks 39, a6, 50, and 51, and particularly the anvil surfaces thereof, should be as hard as possible to prevent upsetting, but should not be sufliciently brittle to chip or permit pieces to break off. The shank portion of all of the anvil blocks and particularly the juncture of the shank and the flange, which should be rounded, should be comparatively soft to prevent crystallizationat that point. 1 r

The grooves 52 and 53, and the inlet ports 32 and 33, and the exhaust'ports 34 and 35 should be so spaced that the groove 52is o. .posite the exhaust ports 34 and the groove 5 is opposite the inlet port 33 when the plunger is in its lowest position as shown in Fig. 4, and'so that the groove 52 is opposite the inlet port 32 and the groove 53 is opposite the exhaust ports 35 when the plunger is in its uppermost position.

'Ih e'modification shown inFig. 5 eliminates the plate 21 and the key 19 and the nut 20 but, in this instance, the vibrators B should be closely fitted endwise in the legs. If this is not done, the screws'18 willbeco ne loose aftef short use of the vibrator, thereby not only mitigating theeffect of the vibrators, but also causing thescr'ews 18 to crystallize. The operation of the -mechanism shown and described 'is asfollowsz The plunger hein in its down position, due to itsfown we twheni fluldwptessureis shutefi, as

shown'in Fig. 4. Fluid pressure is now turned on "by means of the valve 23 andflows into the pipe 22, through the hose portions 26, into the pipes 28, and into the openingsBl. Both vibrators are now read for action and will act independent of see other but the action of both are alike hence the operation of one vibrator only will be described.

The plunger being in its lowest position, the inlet port 33 registers with the groove 53 and fluid pressure now flows from the opening 31, into tlieport 33 andthe groove53, through the port hole 55, and into the space 56. The fluid pressure now forces, the plunger upward until it strikes the anvil block 39, which action creates vibrations in the block 39 and these vibrations are transmitted to the cylinder 29 and to the legs and to the flask C which is suspended on the legs.

.During this upward l'novenient of the plunger, the groove 52 registers with the exhaust ports 34- and the fluid pressure now in the space 57 exhausts through the port holes 54, the groove and the exhaustports 34. 7

When the plunger reaches this upper position, the groove 52 registers with the inlet port 32 and the groove 53 registers with the exhaust ports 35. Fluid pressure now flows from the opening 31, intothe port 32, into the groove 52, and through the port holes 54 into the space 57 and forces the plunger down-until it strikes the anvil block 46, which action again creates vibrations which are transmitted to the cap 37 to the key 19, tothe legs, andto the flask C.

During this downward movement of the plunger, .the groove 53 registers with the exhaustports 35 and the fluid pressure now in the space 56 exhaust through the port holes 55, theg'roove 53, and the exhaust ports 35.

. This operation of the apparatus and both i of the vibrators is repeated automatically and continues to repeat'as long as fluid pressure is supplied.

It is noted that a seriesof exhaust ports are provided at each exhaust position of the cyl-' inder for the purpose of complete and quick exhaustion, so that no resistance acts on the plunger and so that the plunger strikes the anvil blocks with full force and creates sharp vibrations. V i i It will further be seen that theapparatus of the present invention is efficient since there are few parts, the parts subject to Wear are easily replaced, sharp and effective vibrations are created, and these vibrations are effectively transmitted tothe object operated upon by metal to metal contact.
