6 Claims.

This invention relates to improvements in shaker conveyers and more particularly relates to a new and improvel swivel for permitting one trough section of a shaker conveyer trough line to deliver material to another trough section of the conveyer trough line, when positioned laterally with respect to said other trough section.

The principal objects of my invention are to provide a new and improved form of swivel for a shaker conveyer trough line including a novel means for controlling the path of swinging movement of the laterally swingable trough section of the conveyer.

A more specific object of my invention is to provide a novel form of articulated connection between two trough sections of a conveyer including a pair of crossing links pivotally connected at one of their ends to a fixed base and having pivotal connection at their opposite ends with a sliding support means for the laterally swingable trough section of the conveyer, for controlling the path of swinging movement of said support means.

Other objects of my invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawings wherein:

Figure 1 is a plan view of a swivel constructed in accordance with my invention, with certain parts broken away and certain other parts shown in section in order to more clearly illustrate certain details of my invention;

Figure 2 is an enlarged longitudinal sectional view taken substantially along line 2-2 of Figure 1;

Figure 4 is a partial fragmentary transverse sectional view taken substantially along line 4 -4 of Figure 1;

Figure 5 is an enlarged detail view showing certain details of the anti-friction mounting for the reciprocating trough section;

Figure 6 is an enlarged detail sectional view taken substantially along line 6-6 of Figure 1; and

Figure '7 is an enlarged detail sectional view taken substantially along line 1-1 of Figure 1.

In the drawings the embodiment of my invention illustrated is shown as providing an articulated connection between a driving trough section II! and a driven trough section II of a shaker conveyer trough line, to permit materialto be carried from the driven to the driving trough section when the driven trough section is positioned laterally with respect to the driving trough section, so the conveyer may carry material around corners or $0 a pick-up member on the forward end of the driven trough section may pick up material from the extreme corners of a wide room or may be extended along a cross cut or entry at an angle to the main part of the conveyer, to pick up material therefrom.

The articulated connection between the driving and driven trough sections of the conveyer includes a base I2 adapted to be firmly held in position on the ground during reciprocation of the conveyer by means of a plurality of jacks l3, l3 engageable at their lower ends with sockets I4, I4 in said base and with the mine roof at their upper ends.

A connecting trough section l5, having a widened outwardly flared receiving end, with curved sides, is reciprocably mounted on said base on a plurality of aligned laterally spaced grooved rollers IT, IT rotatable about parallel vertical axis. Each of said rollers, as herein shown, is journaled on a vertical shaft I8. Said shafts are mounted on the base l2, as their lower ends, and extend through a support member l9 mounted on and extending longitudinally along said base and over the top of said rollers. As herein shown, four rollers are provided on each side of said connecting trough section, although any desired number of rollers may be provided, and each group of spaced rollers is adapted to have supporting engagement with a longitudinally extending rod 20, engaging the grooved portion thereof.

Said rods are mounted on and extend along the lower portion of a frame 2|, which forms a support for said connecting trough section.

The forward end of the trough section 10 is adapted to be connected with the forward end of the connecting trough section by means of the usual connecting bolts 23, 23 extending through abutting eyes 24, 24,

A forward connecting trough section 25, similar to the trough section I5, is mounted on the base in forwardly spaced relation with respect to said trough section on a reciprocably movable support frame 25. Said frame has a pair of laterally spaced depending longitudinally extending rods 21-, 21, which engage the grooves or grooved rollers 28, 28, mounted on a transversely slidable plate 29. Said rollers are mounted be- .tween the top of said plate and the underside of the upper portion of laterally spaced longitudinally extending support members 30, 3!], on vertical shafts 3|, 3|. Said slidable plate is movable transversely of said base, so the entire support for said forward trough section may be laterally moved across said base. Said forward connecting trough section is connected with the driven trough section II by means of the usual connecting bolts 33, 33 extending through laterally spaced eyes 34, 34.

An intermediate trough section 35 having outwardly curved sides, at its ends, which conform to the form of the forward and rear connecting trough sections i5 and 25, is provided to bridge the gap between the connecting trough sections 25 and i5. Said intermediate trough section is pivotally connected at its ends, to adjacent ends of said connecting trough sections and has the discharge end of the connecting trough section 25 nested in the forward end thereof and is nested within the receiving end of the connecting trough section it. Said intermediate trough section bridges the gap between said connecting trough sections and also splits the angle between said trough sections, to eliminate abrupt turns from one trough section to the other and to prevent the piling up of material at the turn.

The intermediate trough section it has a stub shaft 3t secured to and depending from its bottom and journaled in the frame 25 on a bearing 37, mounted in a bearing sleeve mounted on said frame. Said sleeve extends through a bored portion of said frame and upwardly therefrom through the connecting trough section i5, forms a mounting for said connecting trough section on said frame.

The opposite end of the intermediate trough section 35 underlaps the forward connecting trough section 25 and is mounted on a bearing sleeve till, secured to the frame 2% and projecting upwardly therefrom. Said forward connecting trough section has a stub shaft :23 secured theret and depending therefrom, which extends through a bearing mounted in said bearing sleeve. The driven trough section ii and forward ccnnecting trough section 25 may thus be transversely moved across the base i2 about the vertical axes of the stub shafts St and d3.

Referring now in particular to the novel means for controlling transverse .iovement of the plate 253 and the roller support for the forward connecting trough section 25 across the base plate 2, to cause the plate as and rollers to move in the same path as the path of movement of the connecting trough section 25, pair of crossing control links Q5 and t! are provided. The furcations of the rear bifurcated end'of the link 66 extend on opposite sides ofa bracket member id, mounted on the base l2. Said link is pivotally connected to said bracket member by means of a pivotal pin t and extends fromsaid bracket member diagonally across said base, and its forward end is pivotally connected to a bracket member 55, projecting rearwardly from the plate 29, by a pivotal pin 52.

The link t? is like the link it, but its bifurcated end portions are so arranged that said link will cross under the link 35, asis shown in Figures 1 and 6. Said link is pivotally connected to a bracket 53, at its rear end, by means of a pivotal pin 5%, and is connected to a bracket 55 at its forward end by means of a pin 55. As herein shown, the pivotal pins 5 5 are positioned equal distances from opposite sides of the stub shaft 36 and are spaced forwardly therefrom a slight distance and the pivotal pins 52 and 56 are mounted on the plate 2%} beyond the rear end thereof and are laterally spaced the ii" n same distance apart as the pins 55 and E4 and equal distances from the center of the shaft 43. Said links, crossing each other, thus form a controlling connection between the base and the plate as, for controlling the path of movement of said plate so it will move about the spaced vertical axes of connection of the intermediate trough section 35 to the connecting trough sections I5 and 25.

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