section is secured at its forward end to the driven
trough section I3 by means of connecting bolts
21, 2T extending through .aligned eye pieces 28, 28
in adjacent ends of said trough sections.
The shoe I9, as herein shown, is circular in
form having an upturned periphery to permit
ease in sliding movement along the ground, and
has an upwardly extending hollow. cylindrical
central portion 34. Said hollow cylindrical por
tion is adapted to be engaged by the inner pe
riphery of the depending walls of the hollow
cylindrical frame 24, thus forming a pivotal and
slidable connection between said frame and said
upwardly extending central portion of said shoe.
The means for vertically adjusting the frame
24 with respect to the shoe I9 includes a thread
ed shaft 35 secured at its upper end to a boss
36 disposed centrally of the cylindrical wall por
tion of said frame. The depending end of said
threaded Shaft is threaded within a threaded
member 3l disposed centrally of the cylindrical
portion 34, and herein shown as being formed
integral therewith. A handle 39 is secured to
the shoe I9 and projects outwardly therefrom.
25 This handle is adapted toV receive the end of a
pipe (not shown) or any other means for ob
taining a mechanical advantage for turning said
shoe and thus elevating the frame 24 Yand the
connecting trough sections 20 and 25 with re
30 spect to the ground in an obvious manner.
'
It will be seen from the- foregoing that a
simple form of swivel has been provided for con
necting two portions of a shaker conveyer trough
line together and permitting one to swivel with
respect to the other in a horizontal plane, which
swivel is so arranged as to aiîord vertical lad
justment of adjacent ends of these sections of
a supporting shoe adapted to rest on the ground,
a connecting trough section mounted on Said
shoe for pivotal movement with respect thereto
about a vertical axis, another connecting trough
section mounted for movement with respect to
said ñrst trough section about a coaxial ver
tical axis, said shoe having a hollow upwardly
extending cylindrical portion, a hollow cylin
drical frame extending downwardly from one of
said trough sections adapted to have pivotal en
gagement with said cylindrical portion, a sup
porting connection between said frame and
trough section, means for rotatably moving said
shoe, and an interengaging elevating connection
disposed within said frame and cylindrical por
tion for elevating said frame and trough sec
tions with respect to said shoe upon rotation of
said shoe.
3. In a swivel for shaker conveyer trough lines,
a supporting shoe adapted to rest on the ground,
a connecting trough section mounted on said
shoe for pivotal movement with respect there
to about a vertical axis, another connecting
trough section mounted for movement with re
spect to said first mentioned trough section about
a coaxial vertical axis, said shoe having a hollow
upwardly extending cylindrical portion, a hollow
cylindrical frame extending downwardly from
one of said trough sections and adapted to have
pivotal and slidable engagement with said cylin
drical portion, and an elevating connection be
tween said frame and cylindrical portion for
elevating said frame and trough sections with
respect to said shoe upon rotation of said shoe
including a threaded shaft disposed centrally of ,
said frame, and an internally threaded member
disposed within said cylindrical portion and hav
the pan line and thus permit one trough sec
tion to be disposed along a ledge above the mine
ing threaded engagement with said shaft.
It will also be seen that the means for affording
a connecting trough section, and a vertically

bottom and gather mined material therefrom. ' a supporting shoe adapted to rest on the ground,
vertical adjustment of the trough sections is of >adjustable supporting connection between said
a simple and compact form so arranged that trough section and said shoe including a cylindri
rotation of the supporting shoe for the swivel cal frame member depending from said trough
causes vertical movement of the trough sections sectionl and having pivotal and slidable engage
ment with an upwardly extending cylindrical por
with respect thereto.
While I have herein shown and described one tion of said shoe, and means for elevating said
form in which my invention may be embodied, cylindrical frame member with respect to said
it will be understood that the construction shoe upon rotation thereof including a threaded
thereof and the arrangement of the various parts shaft mounted within said frame member and
may be altered without departing from the spirit having threaded engagement with an internally
and scope thereof. Furthermore, I do not wish threaded member disposed within said cylindrical
to be construed as limiting myself to the speciñc portion.
