rI'his invention relates to improvements in endless conveyers primarily intended ifor use in connection with `elevating grading machines. In suchv nmachines the elevator that extends laterally from the wheeled iframe ol the grading machine is Ausually of considerable length sons to carrythe dirt that is deposited on it in the usual manner to the proper distance to discharge it over the upper end of the elevator into awagon or other vehicle standing at a distance rom the side or' the machine. `Various mechanisms are provided f on the machinejfor varying the inclination of the elevator, and in order not to have to adjust the entire elevator each time that it is desired to vary the'height of, the discharge end of' the elevator-.it has been common to construct such elevator of two alined sections hingedI together so Ythat the outer section alone could bemovedvertically to secure the desiredheight ofthe discharging end. Such jointing or hingingtogether of the two sections in former constructionshas, however, beenobjectionable in that by reason of wear f or slight imperfection of lit ot the hinge mem-v bersthe axes of the'sprockets carried by the two sections and over which. the drive chain runs,.and also the axes of the drums or rollers at the endsoil the elevator frame, vwould not be in perfect parallelism, as of course is necessary for perfect driving and smooth, easy movement of the endless convcyer Athat runs over such drums or rollers. ItV is the object of .my invention to provide'improved means for so connecting the two sections of such an elevating apparatus ltogetherthat they can be brought into'pertect'lateral alinement and so maintained, and thus, because of the resulting parallelism of the axesy of the driving sprockets and of the drums or rollers that the belt runsl over, ensure the desired smooth and accurate movement of the belt.

Fig. l is a side elevation of inner end portions of the two sections of a grading machine elevator, said sections being connected together bymeans embodying the invention;

ligz is view partly in plan and partly in horizontal section y illustrating theV improved connection of the elevator sections, some of]V the elevator rparts being partly broken away; andl Fig. 3 is a vertical crosssection taken substantially on the line of Fig. l.

ings,-l0 and lO:l indicate the side members of the inner and outer sections or" the elevator frame of al grading machine, which sections are hinged together ior relative vertical swinging, and, as hereinafter particularly de scribed, are so connected that at all times the corresponding side members of both sections may be maintained in the same vertical plane, whereby the axes of the sprockets of the driving mechanism, and the axes of the rollers over which the conveyer belt runs will always be parallel-it being` understood that one of the sprocket wheels will be mounted upon one y each elevator frame section are a plurality of brackets 12, one of which is shown in connection with each section, which brackets project above the upper margins of the members 10, l0:L and overhang the belt l1, as shown in Fig. 3, and to such brackets are secured side boards 13 whose lower edges are close to said belt, so that such side boardsform means for retaining-on the belt the dirt that the belt is carrying for delivery Yfrom the lower to the upper end thereof. 14 indicates rollers ournaled at intervals on the elevator frame and acting as intermediate supports for the belt 11i, as usual. The side boards 13 are preferably formed of channel iron, as clearly shown in Fig. 3, and the adjacent ends of said side boards are offset and overlap, as shown in Fig. 2, so that, together with the4 belt, a continuous unbroken passage is formedV from oneend of the elevator to the other. As shown in `Figs. l and 2, the lianges of the side boards lare cut away adjacent to their adjoining ends sufficiently to permit of vertical .movement of one section relatively 'to the other whenfthe outer section of the elevator, which is the/one the side members oit which are here indicated by l0, is independently moved to raise or lower its upper or discharge end. y

The two elevator frame sections are hingedly secured together by similar devices secured at opposite sides of the elevator, as clearly shown in Fig. 2. As shown, each of the two side members of one of the frame sections-those numbered 10 in the construction shown-has bolted. to it a stationary hinge member 15 in the form of a bar having a yoke-shaped head 16, which head projects beyond the outer end olf the side member to which it is secured. rlhe cooperating hinge members 17 are connected with the side members 10 of the outer trame section and each is in the form of a stem, preferably angular in cross-section, as shown in Fig. 3, having a yoke-shaped head 18 similar' to the other head 16, and a screw-threaded shank 19 that, as clearly shown in Fig. 2, is oiliset relatively to tie stem so as to lie at a distance from and substantially parallel with the side member 102L of the elevator frame with which it is connected. rl`he hinge members 17 are not bolted or immovably fixed in place as are the hinge members 15, but the stem ot each hinge member 17 is slidingly supported against a side member 10fi of the elevator frame by guide means in the orm of a hood or casing 2O that is shaped to approximately conform to the shape of the stem, such hood or casing being secured to the side member 10d by bolts 2l, as best sh own in Fig. 3. Preferably this hood or casing will be ribbed as at 2Q for strengthening purposes. The offset screw-threaded shank 19 of each hinge member 17 passes loosely through an eye in an abutment or bracket, 23 that is bolted to the face of the adjacent side member 10'VL and upon opposite sides of this eye are nuts 24 that are screwed upon the shank 19. 25 indicates a pintle that passes through the two interlapping yokeshaped heads 16 and 18 of each pair oi* hinge members for the purpose of pivotally connecting them together.

1t will be evident that with the two sections ot an elevator iframe hingedly connected together in the manner described, the outer or upper section of the elevator frame can be swung up or down to raise or lower its discharge end as may be required to suit varying conditionsand it' for any reason the connection of the two sections is such that the outer section becomes slightly deflected laterally so that the axis ot the sprocket wheel, and the drum or roller that it carries, is not in perfect parallelism with the similar parts carried by the other section, such deviation rom parallelism can be very easily remedied, as all that need be done is to loosen the nuts 24, and then, after swinging the outer section laterally to bring it into lateral alinement with the other section, said nuts can again be tightened up against their respective eyes 23 to hold it in position. IThe slight lateral shifting necessary to produce this correct alinement can be accomplished by loosening the proper one of each of the pairs of nuts 24 and then screwing up the other nuts of such pairs so that when the two sections are properly alined the apertured ear portion of each bracket 23 will be lirmly clamped between the nuts. The holes in the brackets through which the Shanks 19 pass are of sufliciently greater diameter than such shanks to permit this sidewise adjustment to be readily made, and during such adjustment the stems of the hinge members 17 slide easily in the guides formed by the hoods 2O and the adjacent outer faces of the frame members 10a to which such hoods are secured.

By my invention perfect alinement of the two sections is always easily attainable, and consequently the sprockets that are carried respectively by the two elevator frame sections may be kept in proper alinement so that excessive wear on the chain and sprockets will be prevented and the belt caused to run smoothly and evenly.

Vhat I claim as my invention and desire to secure by Letters Patent, is`

An elevator for elevating graders comprising adjoining inner and outer frame sec-- tions, an endless belt supported by said sections, hinge members connecting said sections together for relative vertical swinging, guide means for one of said hinge members permitting longitudinal shifting motion of said hinge member relative to the section on which it is mounted but preventing swinging motion thereof relative to said section, and screw threaded adjusting means for effecting 1ongitudinal shifting motion of said latter hinge member, whereby said inner and outer frame sections can be relatively adjusted laterally with reference to the run of the belt.
