8 Claims.
This invention relates to screening apparatus for cleaning and block knock-out work, and more specifically to a screening apparatus used in foundries and similar plants.
The prime object of the invention is to design a gyrating screening apparatus for causing the cores to be loosened, andthe core sand toflow out' of the block and/or castings as they travel over the screen. l
l0 Another object is 'to provide a gyrating screening apparatus for vibrating castings, etc., and provide means extending into the path of travel of the castings for loosening and cleaning off the sand, slag and other foreign matter adhering to the casting or held on the at surfaces thereof.
A further object is to design a gyrating screening device which is adapted for use in foundries and shops in general for vibrating, brushing and/or cleaning hot castings, such as' cylinder blocks, etc., as they travel through the machine.
Still a further object is to provide means for supporting the weight of the castings above the screening surface in such a manner that there will be no internal strains set up in the castings,
and provide means for retaining the cores in the casting so that they will, at a predetermined point, be discharged into a bin or other receptacle and separated from the core sand and slag.
With the Vabove and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the 3,', appended claims, it being understood that changes may be made in the form, size, and proportion and minor details of construction, without departing from the spirit, or sacriiicing any of the advantages of the invention.
.lo In the drawings:
Fig. 1 is a side elevational View of my gyrating screening apparatus showing a cylinder block in the machine.
Fig. 2 is a top plan View thereof.
Fig. 3 is a transverse sectional View taken in the line 3-3 of Fig. 2.
Fig. 4 is an enlarged detail plan view of one of the resilient iingers, the broken lines showing it sprung.
Fig. 5 is an enlarged sectional view of the gyrating assembly.
Fig. 6 is a fragmentary part sectional view showing the resilient corner mounting.
The cleaning and handling of hot castings as Vthey come from the moulds is quite dicult due to the heat and Weight, and further, because it is difficult to force out and clean all of the cores,. cored openings, and flat surfaces and ledges to which core sand, slag and other foreign matter will adhere, and I have therefore, designed a gyrating screening apparatus which vibrates and cleans the castings so that the sand and slag is removed, which collects the cores and core sand, after which the castings can be either mechanically or manually handled in an efficient and 10 practical manner.
In the accompanying drawings I have shown a screening apparatus B which in the present instance comprises a pair of spaced apart longitudinally disposed plates I0, which form the side 15 walls of the screen frame, said frame being connected to a gyrating shaft assembly II which includes a shaft I2, the ends of which are journaled in bearings I3 provided on the longitudinally disposed frame supports I4, these supports being slightly inclined, and are mounted on posts or foundations I5 as usual.
V Transversely disposed braces and plates I6 and Il respectively secure these side plates in spaced apart relation, and longitudinally disposed mem- 25 bers I8 are mounted on the members VI6 and are connected to the plates II by knee braces I9 as usual.
Power for the operation of the apparatus is supplied from any suitable source, a pulley 25 being provided on one end of the shaft I2 which forms a part of the gyrating mechanism, and can be connected to any satisfactory power plant, or an electrical motor can be mounted on the machine and connected direct to the gyrating shaft assembly, if desired, and I do not deem it necessary to describe this gyrating assembly in detail,
A central longitudinally 35v as it can be of any desired design for agitating,
Vvibrating and/or gyrating the screen.
The'block 24 is placed on the upper end of the VVtrack 20 and the gyrating or vibrating pitched frame andV action of the screen mechanism causes it to travel downwardly on the tracks, the Vcores 23V shaking loose and riding on the T-shaped member 22, the vibrating of the screen' loosening the Ycore sand, slag, etc., which screens through the screen 2| into a suitable hopper or bin (not shown) provided for the reception thereof.
the block travels along, the rows of fingers 26,
which are mounted 'on the side walls 21f1n cer-y tain predetermined positions, engagesthe' at surfaces and ledges on theblock,rcleaning'oiv` the sand, etc., and lwhile I have'shown 'sets of spaced apart resilient lingers 26, it will be obvious that brushes or other cleaning `members may be substituted, if desired.
. It Will be noted that the screen 2l does not ex- Y tend ithe Lentire length of ,the machine, conse- 4:5v Y walls,k wor supporting tracks secured to saidV quently, when the block v24 passes the end of thescreen, Vthe cores 23 dropthrough into a hopper 28, and from which th'ey'areremoved or discharged as desired, the cores vbeing thus separ'at'etlfrom the core sand, slagfjetc.
. The yshaft assembly Il is located'subst'antially in :the longitudinal center of lthe 4screen, andv I therefore, provide resilient .corner mountin'gs 29, angles `3l) being secured to the side plates I', and
Vresilient members 30a are interposed between thseangles andthesupports I4 so thatjprop'er gyrating action is assured."
v The gyrating'shaft I2 is'turn'ed at 3l and is mounted in thebearing 32'as usual, the tubular casing 33 is bolted to the sideplates I0', thus providinga 'dust proof construction.
From the foregoing description it y,will be obvious that I have perfected a very practical, sub'-V stantial and emcient screening apparatus for cleaningy and block core'knockout'work in general.A
What I claim is:
1.' screening'apparatus of the class described andco'mprising a base, a gyrating screen frameV mounted thereon and including 'spaced apartside sidewalls and adapted' toV support'the work, a
screen interposed between said tracks, and driven means for gyratingsaid'irame.
2.'In `ai screening apparatus `of the class dei scribed and including asupporting` baise, a screen frameA Ymounted on the base, inclined tracks mounted on the screen frame and on which the work is adapted to travel, and a'gyrating mechanism drivingly connected to said'frame for posiy:tively gyrating said frame.
Y '3. A screening apparatus for cleaning and Y of the screen,
block core knock-out work, comprising a stipporting base, a screen frame mounted on said base including a screen, spaced apart tracks mounted on the frame and extending beyond the ,one end thereof, saidtracks being adapted to support the work, and a gyrating means connected to said frame for positively gyrating the frame and tracks. Y Y i "4. In a screening apparatus forV cleaning and block core knock-out Work, in combination, a base,
' `arscreen frame mounted thereon and a screen carried bysaid frame, tracks on said frame and adapted to support the work, a core retainingY member mounted on the face of the screen for preventing contact kof the cores with the screen,
.and means for gyrating said screen frame.
5. A screening apparatus for cleaning and block vcore knock-out work, comprising a screen frame,
including'spaced apart side plates, a screen car-` riedby the frame, spaced apart tracks secured to the side fplat'es 'and adapted' to support the work, avc'orle retaining member mounted on the face ofthescren for holding said cores from contact with the face of the screen during the progressof thebl'ock thereoven a hopper for receiving'the cores'afte'r the V'block has traveled past theend'of said screen, Vand means for Y gyrating's'aidscreening apparatus.4
6. In ascreeningapparatus forcle'aning ca'st-Y l30' into the path of traveloi'the work, and means for positively 'gyrating said frame.
8. Inv a screening apparatus for cleaning and block core knock-out work, in combination, asupporting base, a Vframe mounted thereon and in' cluding 'an' inclined" screen, tracks mounted Yon thefframe andadapted'to' support thefwcrk as it travels overthe screen, resilient'nngers sei cured to' the sidewalls of the frame and Vproj'Cting itd the path of travel Off-the Work, a core fr'eceivingl hopper adjacent thef lower end 'and means for positively gyrating said `frame. l,
