(Cl. 51--6l 1 . 2 of the dumper, for discharge of graining elements The invention herein disclosed relates to grain thereinto, when the table is tipped. :lng machines of the type disclosed in the Zarkin The trap door is shown as carried by a rec Patent 2,674,633 of March 23, 1937, and partic tanguiar, angle iron frame 2l, secured over the uiarly to the dumper mechanism for returning back of the bottom, as a frame about and be the graining elements to the oscillating tub. neath the trap door opening 22, in the bottom Objects of the invention are to improve the wall 23. Hinge brackets 26, are ,carried by the dumper mechanism in structure and operation upper bar of this frame and these carry the for and in particular, to eliminate any possibility of wardly or upwardly offset hinge knuckles 25, con the marbles, steel balls or other graining ele ments becoming caught in the trap door of the 10 nected with the trap door plate i9. The latter as shown in Fig. 5, seats on the angle iron frame dumper. 2i, within the trap door opening 22. Other desirable objects attained by the invene The upper edge of the door plate is shown as tion are hereinafter set forth or will appear in cutwardìy or upwardly bevelled at 25, to match the course of the following specification. The drawings accompanying and forming part 15 the inwardly and downwardly bevelled upper edge 2l, of the door opening, to fully close any of the specification illustrate a present com gap between the bottom or ñoor of the dumper mercial embodiment of the invention.

This prevents any graining ele this particular illustration, all within the true intent and broad scope of the invention as here- 20 ments or other solid material from getting into the hinge joint as the dumper is lowered and at inafter defined and claimed. the same time, leaves the bed of the dumper Fig, l is a broken plan of the graining tub smooth and iiush to run ofi the graining elements and dumper mechanism. into the tub when the dumper is raised and Fig. 2 is a broken part sectional side elevation of the same. Fig. 3 is a broken sectional detail on substan tially the plane of line 3-3 of Fig. 2. Fig. 4 is a View similar to Fig. 2, but showing the dum er lowered from the position first illus trated. Figs. 5 and 6 are enlarged broken sectional views of the trap door in the two positions shown in Figs. 2 and 4. 25 the trap door is closed as in Fig. 5. The lower edge of the trap door, at the upper face, is shown as downwardly bevelled at 28, to avoid any abrupt shoulder at this point, which 30 ' In the machine illustrated, the graining tub l, is carried by a frame S, mounted for oscillat ing movement on the base 9, and the tub is piv otally connected with the frame at one end at iii, so that it may be tilted to run off the drain ing elements through a spout l l, into a convergent 40 inclined tray or trough I2. The dumper i3, is carried by trunnions I4, journalled in pedestals lìland is rocked by means oi a crank arm i6, on one of the trunnions, con might interfere with or retard flow of> the grain ing elements back into the tub, when the dumper is raised and the door is closed as in Fig. 5. The return chute l2 is shown as adjustable for purposes of changing its inclination, by being fulcrumed at the outer lower end over the bar 29, and by having lugs 3i), toward the upper end of the same engaged in slots 3l, in brackets 32, on the pedestals I5, and secured in adjusted re~ lation by wing nuts or other suitable íastenings 33, in Fig. 3. The angular frame about the trap door open ing reinforces the bed c1" the damper, enabling it to safely carry heavy loads of graining mate rial without warping and the inner portion of this frame, where it extends inwardly beyond this nected with the piston Il, of a power cylinder, 45 opening, forms a ñrm solid seat for uhe trap door, the latter not shown. supporting and holding this door in iiush relation In the` raised position, Figs. 1 and 2, the lip of with surrounding portions of the bottom wall, as the dumper reaches over the end of the tub to will be clear from Fig. 5. This frame also serves pour the graining elements into the tub in front as a substantial and rigid mounting and support of the upraised dam I8. In the lowered position, Figs. 4 and 6, a trap 50 for the trap door hinge. The hinge leaves 2d, may be secured to the frame and hinge leaves 25, be door it, hinged at its upper end in the bottom secured to the trap door before these parts are ci the dumper, is forced open, by engagement applied to the dumper. Then, after the frame is over correspondingly inclined rearward corner secured, as by welding or otherwise, in position edges 2t, cf the chute i2, to thereby admit the lcwer'end of said chute into the lower portion 55 on the back of the bottom wall, the 'door may be 3 2,413,899 dropped into position on top of the frame and the hinge pin or pins 34, then passed through the aligned hinge knuckles.
