.Application filed .Tanualy 11, 1923. Serial No. 611,988.
To (ZZ '107mm itJ may cancer/n:
Be it known that I, AXEL Gr.` J. RAPP, a citizen ofl the' United States, residing at Chicago, in. the county of Cook and State of Illinois,.have invented a certain new and useful Improvement in Casting-Handling Machines, of which the following` is a specification.
vThis invention relates to a moving table which is intended primarily for the handling of castings, and is designed particularly asa means for removing the sand cores .from the castings and for collecting` the sand. One object is to provide in a machine of thetype suggested an apparatus which will permit ofyery great capacity wherein a large numberof castings may be rapidly 'cleaned and which. will occupy a limited space. Another object is to provide a means which will readily recover and=collect the `greatest possible proportion of the sand. vOther objects will appear from time to time /throughontthe specification and claims.
My inivention isfmore or less diagram- 'matieally illustrated in the accon'ipanying dra-wings, wherein:
i Figure l1 is a plan View of one form of the. appa-ratus;
:Figure 3 is a partial cross section ona an :'enlarged seal-etaken on line 3-3 of Figure 1 showing particularly the table supporting means;
` Figure :is a partial cross section taken on line 4-4 of Figure 1 showing one form of the driving means.
Like parts are designated by like characters throughout.
'The table is preferably circular and is tmountedfor rotation. The table consists of an inner bandA'and an enter peripheral bandiAl. Eachofthese hands has on its r'Jinn-er face a grate supportingangle B.
The inner bands are joined by attaching means C. Projecting vertically downward from the inne:` band Av are a plurality of members Dv to which maj/be secured gnsset plates D1. Projecting inwardly and'downwardly fromthe" outer member A1 are a plurality of bracing members E. i These members may have additional supporting` gusset plates E1, and extend downward toward the downward end of lthe members D.
labout a roller L1.
Beneath i the upper surface of the table and parallel to itiand attached to the members D and E are supporting membersF.
Supportednpon the members F, fastened to the'inner'an'gles li and supported by` the 'and downwardly toward` themember G but leaves an opening Ggathrough which sand may be discharged from the hopper.
About the inner edge of the table is mounted an angleiH. Below this is a second angleH1 which has seeured to its under face an inverted rail HQ.
At suitable intervals about the interior of the table are mounted supporting members -which carry bearing's 11. From these bearings, upon axles 12 are supported aA plurality of wheels 13. The rails H2 rest upon and are supported by these Wheels.
'Mountedat the bottom of the table on its inner side is an annular rack J. Meshing with this rack is a'pinionJ1 carriedby a shaft J' which is driven by a motor J3 through a reducing gear Jt. This driving mechanism is not shown in great detail as vit'forms no partof the invention.
Extending snbstantially about1 the table and lyingadjacent to the horizontal portion ofthe hopper member G is a skirt orzscreen K whic-hserves as a Safety guard member for the worlnnan and those working about the machine to prevent injuring them.
L is a conveyor, here shown as an endless belt` conveyor, although another :form of conveyor might be substituted. This con- Veyor extends under the table and runs Discharging' upon the conveyor is a chute L2. Material is directed into thechute from the hopper by means of the plow L3. This plow extends diagonally across the horizontal portion of the part G of the hopper, and as the table moves the sand is directe'd by the plow into the hopper and so into the conveyor.
Resting in the angles B B are a plurality of removable grid Sections. These Sections are formed of=a number of longitudinal rods M M upon which are ;nounted a plurality of barsM'.
Although I have shown an operative device, still it will be obvious that many changes in size, shape and arrangement ofV parts might be made without departing materially from the spirit of my invention, and I wish therefore that my showing be taken as in a sense diagrammatic.
The use and operation of my invention are as follows:
The castings as they are formed are placed upon the grills on the top of the table either by hand or by any simple mechanical conveyor.- As the table rotates the sand cores are'removed fromV the castings. They may be driven out by hand or Vr'emoved in any suitable fashion. The Sand as it Vfalls from `the castings falls through the grill's and down into the annular hopper. As the table carrying the hopper with .it moves, the
plow extends into the path of the sand and thus scrapes it from the horizontal portion of the hopper member and directs it into the chute. From the chute it falls into the conveyor, and is thus removed.
I clam:
1. In combination 'in a casting handling machine an annular table adapted to support castings and provided with passages therethrough to permit material from the castings to pass downwardmounted for rotary movement, an annular hopper beneath said table fastened' thereto, there being an extended open space inside of said table substantially free from obstructions.
2. In combination in a casting handling machine an annular table adapted to support castings and provided with passages therethrough to permit material from the castings to pass downward' mounted for rotary movement, and an annular hopper beneath said table and attached thereto, a
laterally eXtending plate beneath said hopper attached thereto of such width normally to prevent discharge from said hopper.
' 3. In combination in a casting handling' machine an annular table adapted to support castings and provided with passages therethrough to permit material from the castings to pass downward mounted for rotary movement, and an annular hopper beneath said tableand attached thereto,-
having a discharge passage at the bottom thereof, a laterally extending plate beneath said hopper attached thereto of such width normally to prevent discharge from said hopper, and a .plough held stationary and extending over said plate and adaptedV to remove material ltherefrom.
4. In combination in a casting handling machine an annular table adapted to support castings and provided with passages therethrough to permit material from the castings lto pass downward mounted for rotary movement, and an annular hopperv beneath said table and f attached thereto having a discharge passage at the bottom thereof, a laterally extending plate beneath said hopper attached thereto, of such width normally to prevent discharge from said hopper, and a plough held stationary and extending over said plate and adapted to remove material therefrom7 in combination with a conveyor adapted to receive material transmitted thereto by said plough.
