-Referringncwginparticularitothe'details shown -inV thedrawing, `a-conveyer trough `111'1 i is; provided. Said conveyer trough is of an ordinarytypemell knownutoithose skilledlinthe art and is adapted to be supported by a carrier, generally indicated by reference character 12.

Suitable means are provided for effecting an accelerated and retarded movement to the conveyer trough 11 for moving material therealong, which means is of an ordinary type Well known to those skilled in the art and is not herein shown in detail since it is no portion of my present invention.

With reference to the details of the carrier 12, said carrier includes a frame member comprising a plurality of parallel spaced members, herein preferably shown as being angle irons 14, 14, extending transversely of the conveyer trough 11 and connected together by a pair of parallel spaced guide members 15, extending generally long i 'mine ties, as is clearly-shownin Figure `-2.

The roller devices 17, 17 are of an antifriction type and include an inner race 19 having an inwardly extending stud 20 formed integral therewith, an outer race 21, suitable balls riding in said inner and outer races, and an annular housing 23 therefor, which housing also forms a roller and rolls along the guide member l5.

The roller devices 17, 17 are connected together by means of a suitable transversely extending carrier member 24 and with said carrier member form a carriage for the conveyer trough 11. Said carrier member has upturned ends 25, 25 adapted to be secured to the studs 20 by means of suitfics able nuts 26, 26 in an ordinary manner. Said carrier member has a raised central portion, the upper surface of which is beneath the axis of rotation of the roller devices 17, which portion is adapted to support the conveyer trough 11. Said carrier member is provided with a relatively long socket 27 formed therein of substantially the same length as the width of the bottom of the conveyer trough 11 for receiving a depending stem 29 of a T member 30 secured to the undersurface of said conveyer trough and of substantially the same length as the width of the bottom portion of said conveyer trough. The underportion of the cross of the T member 30 is adapted to rest cn the upper surface of said carrier member and be supported thereby so that said carrier member will pivot about the axes of the roller devices 17, 17 when said conveyer trough is pivoted with respect to the angle irons 14, 14. It should be noted that in cases where said conveyer trough is supported in such a manner that it does not rest on said carrier member, that the stem 29 of the T member 30 Will reciprocably move said carrier member upon reciprocation thereof. Such a condition, how-l ever, is not desirable inasmuch as the function of the carrier 12 is to form a movable support for said conveyer trough in such a manner that different angular relations between said conveyer trough and the carrier frame are compensated for due to the fact that said carrier member is pivotally movable about the axes of the roller devices 17, 17.

It may thus be seen that the conveyer trough 11 is supported by the roller devices 17, 17 for movement in the guide members 15 and for pivotal movement about the axes of rotation of said roller devices. Thus the carrier 12 may be set on a mine bottom which is of a different angle than said conveyer trough, and may effectively support said conveyer trough in varying angular positions with respect thereto. It should also be noted that due to the fact that the portion of the transversely extending carrier member 24 which supports said conveyer trough is beneath the axes of pivotal movement of the roller devices 17, 17,.that a supporting means for said conveyer trough has been provided which is of a minimum vertical height and which permits the combined height of the carrier 12 and conveyer trough 11 to be reduced to a minimum.

With reference now in particular to Figures 5 and 6, and a modied form of my invention, a carriage for the conveyer trough 11 is formed by means of a transversely extending carrier member 31 which has pivotal connection with the roller devices 17, 17 adjacent their inner ends for pivotal movement about the axes of rotation thereof. Said transversely extending carrier member has an upstanding central web 33, the contour of the upper surface of which conforms substantially to the form of the conveyer trough. Said upstanding central web of said carrier member is adapted to iit between suitable connecting members 34, 34 secured to the ends of adjacent conveyer troughs for connecting said conveyer troughs together. Suitable sleeves 35, 35 are adapted to pass through suitable apertures in the upstanding central web of said carrier member. Suitable connecting bolts 36, 36 are adapted to pass therethrough and secure adjacent conveyer troughs together.

Thus a rigid connection between the carrier member 31 and adjacent conveyer troughs has been provided which permits said conveyer troughs to be carried for reciprocable movement on suitable anti-friction roller devices and permits said troughs to be pivotally adjusted about the axis of said roller devices to compensate for uneven bottom conditions.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction and arrangement of the parts may be altered without departing from the spirit and scope thereof. Furthermore, I do not wish to be understood as limiting myself to the specific construction illustrated herein, excepting as specifically limited in the appended claims.

I claim as my invention;

1. In a shaker conveyer and in combination with a conveyer trough, a carrier therefor including a pair of anti-friction roller devices, a supporting member carrying said anti-friction roller devices for free rotation with respect to each other, means for supporting said conveyer trough cn said supporting member, and a track for said rollers including parallel spaced guide members having retaining members extending outwardly away from the point of contact of the rim of said rollers with said guide members.

2. In a shaker conveyer and in combination with a conveyer trough, a carrier therefor including a pair of anti-friction roller devices, a supporting member carrying said anti-friction roller devices for free rotation with respect to each other, means for supporting said conveyer trough on said supporting member, and a track for said rollers including parallel spaced guide members comprising angles having inwardly extending horizontal legs forming a generally horizontal track for said rollers and upwardly extending legs extending angularly away from the point of contact of the rim of said rollers with said track.
