2 Claims.
The present invention relates to material separating apparatus of the vibratory type, such as, for example, riddles, strainers and the like and has for its principal object, the provision of separating apparatus of the type mentioned having improved means for mounting the strainer or sifter container, or like separating element, upon the main frame of the apparatus.
A more specific object of the invention is to provide separating apparatus in which the means for mounting the container upon the main frame need not be completely disassembled in order to permit the container to be attached to, or detached from, the frame. The attainment of this particular object is extremely important for it eliminates two of the most serious difficulties encountered with prior arrangements, namely, the loss of connecting parts, such as the nuts and bolts, and the breakage of various parts of the apparatus resulting from a substitution of improperly cooperating parts for the lost parts.
Still another object of the invention is to provide separating apparatus wherein the strainer or sifter container may be easily attached to, or detached from, the main frame.
These and other objects will be more clearly apparent from the following drawings wherein:
Figure 1 represents a perspective view of one form of separating apparatus with the improved strainer or sifter container mounting means of the present invention;
Figure 2 represents a plan view of the apparatus shown in Figure l, the upper portion of the apparatus being broken away to show the container mounting means more clearly;
Figure 3 represents a fragmental elevational view of the apparatus shown in Figure 1;
Figure 4 represents a vertical sectional view through the container mounting means showing the position of the various cooperating parts when the container is held firmly upon the supporting frame;
Figure 5 is a view similar to that of Figure 4 showing the position of the connecting part when the container is only loosely mounted upon the frame, and
Figure 6 is a view similar to that of Figures 4 and 5 showing the position of the connecting parts when the container is free of the frame.
Referring more particularly to the drawings, especially Figure 1 thereof, it will be noted that the separating apparatus shown therein is comvprised of a main frame 2 having a pair of downwardly extending supporting members 4. The lower end of each of these supporting members is provided with a pair of oppositely disposed, transversely projecting footlike extensions 6 which serve to hold, or support, a conventional strainer or sifter container, or other similar separating element 8, which, in the embodiment shown, is provided with a top closure 9.
As customary, the frame 2 is equipped with spring means I!) so that it might be resiliently suspended in operable position from a rigid supporting member (not shown). This resilient mounting of the frame is, of course, necessary to permit the latter to be vibrated to effect the desired separation, the vibratory motion being brought about by any conventional means, such as, for example, an overbalanced weighted rotor housed within the frame 2 and operable through the electrical connection 12. An operating handle I3 is also provided for guiding the apparatus to a desired position over, for example, a foundry mold, or other receiver, for the separated materials.
As apparent from the objects outlined above, the manner in which the container 8 is attached to the footlike extensions 6 constitutes a feature of prime importance to the invention. Specifically, the attaching arrangement includes the provision of a vertical slot in each of the footlike extensions 6, each of the slots in the extensions on one supporting member 4 facing inwardly, that is, opening inwardly towards the other supporting member, as at M while each of the slots IS in the extensions on the other supporting member 4 face outwardly away from the slots I4.
Cooperating with the slots I4 and I6 are outwardly projecting spaced fastening members or bolts [8, which are firmly screwed, or otherwise fixed, in the upper ring 2| of the container 3. The upper ends of the members IB, of course, extend beyond the fiat upper surface of the extensions 6 and receive suitable nuts, or other clamping means, 22, preferably castellated nuts, as shown, the slots being countersunk as best shown in Figures 46 to assist in positioning the nuts 22 as well as to permit a secure connection. Washers 24 of hardened metal complete the connection.
As is readily apparent from the above, the unique container supporting arrangement just described permits the container to be readily attached to, or detached from, the main frame. Specifically, in order to attach the container to the frame, it is simply necessary to raise the nuts 22 a suflicient distance to permit the container fastening bolts l8 to be moved laterally (to the left in the drawings) into the slots [4 and Hi, the castellated nuts 22 thereafter being tightly screwed down into the position perhaps best shown in Figure 4.
To remove the container, it is only necessary to loosen the nuts a distance just enough to clear the upper surface of the extensions 6, as shown in Figure 5, the container thereafter being easily removed by lateral movement to the right as shown in Figure 6. Since the bolts [6 are firmly fastened onto the upper ring, they'remain in projected position even after the container is withdrawn so that, in addition to making possible a connection which need not be completely disassembled to detach the container, they serve the further function of assisting in aligning the container with the cooperating slots in the main frame when the container is to be attached.
Obviously, with the connecting arrangement described, the strainer or sifter container may be easily attached to or removed from the separating apparatus of the present invention. Furthermore, it will be appreciated-that, inasmuch as the connecting parts need'not be completely disassembled to remove the container from the frame, loss of the connecting parts, particularly, the bolts, with resulting breakage of the footlike extensions due to the substitution of improperly fitting materials which soon work themselves loose during operation, is effectively minimized, if not entirely obviated.
It will be apparent from the foregoing description that various modifications in structure can be made Without deviating from the invention. ihus, for example, each of the supporting members may be provided with but one footlike' extension, rather than two as shown. Consequently, it is not intended that the scope of the invention should be limited by the foregoing description but instead should be determined by the.

1. A material separatingapparatus comprising. a frame having a pair of supporting members extending downwardly therefrom, means for resiliently supporting said frame from a rigidsupport, ineans associated with said frame for vibrating. the same to effect the separating action, a pair of foot-like extensions on'the lower end of one of said supporting members, an inwardly facing vertical slot in each of said foot-like extenqicns, another pair of foot-like extensions on the lower end of the other of said supporting. members, said last-named foot-like extensions being oppositely disposed to said first mentioned footlike extensions and each of said last-named footlike extensions having an outwardly facing vertical slot therein, a cylindrical material separating container having a ring about one of its edges, a bolt fixed to, and extending outwardly from, said ring and positioned within each of said slots, the outer end of said bolt being-extended'beyond the foot-like extension with which it is associated and carrying a nut for clamping engagement with said extension.
2. A material separating apparatus comprising a framehavingfla'pair of supporting members extending outwardly therefrom, means associated withsaid frame for. vibrating the same to effect the separating action, an extension at the outer end of "one of said supporting members and transverse thereto, an inwardly facing vertical slot in saidextension, another extension at the outer end oftheother supporting member and transverse with respect thereto, said last-named extension being oppositely disposed to said firstmentioned extension and having an outwardly facing vertical slot therein, a material separating;
