HENRY LIVINGSTON ST. JAMES, OF MARSHALL, TEXAS.
.CONVEYER.
SPECIFICATION forming part of Letters Patent No.705,474, dated.July.22,1902.
Application filed February 11,1902. Serial No. 93,534. (No model.)To all whom it iay concern:
Be it known that I, HENRiY.IvINGSTON ST.
JAMES, a.nitizen .of the'United States, resid-
ing at Marshall, in the countylof Harrison and
5 State of Texas, have invented certain new and.
useful Improvements in Conveyers; and Ido
hereby-declare the following to be a full, clear,
and exact. description of the invention, such
as will enable-othirs skilled in the art to which
1o it appertains .to niake and.use the same.
My invention relates to conveyers, and has
for its object to provide:iiadevice of this class
which is particularly adapted to load or un-
load railroad-car wheels or other heavy ma-
15 terial on or off cars.
A further object of my invention is to pro-
vide a conveyer for the.above purpose which
is particularly simple in its construction and
which' is built with a vie* to' strength and
20 durability. :.
A further object of my invention is to' pro-
vide a conveyer which is so constructed that
it will load or unload scrap car-wheels and
axles on or off cars.
25 With these objects in view my invention
consists in the arrangements of the securing
devices on the slats of the conveyer.
My invention further consists in the par-
ticular method'of fastening the slats of the
30 conveyer to the chain.
My invention further consists in the novel
construction of the chain'sprocket-wheels,and
finally in certain other features of construc-
tion and combination of parts, which will be
35 hereinafter fully described and afterward spe-
cifically pointed :out in the appended claims.
Referring to the accompanying drawings,
Figure 1 is a perspective view of my conveyer
in an operative position. Fig. 2 is a perspec-
40 tive view of the opposite side of my conveyer,
showing the same in operation. Fig. 3 is a
top plan view of the frame or body portion of
my conveyer with the slats removed. Fig. 4
is a sectional vieW* of one of the conveyer-
45 slats, showing manner.of attaching the same
to chain. Fig. '5 'is a front elevation of one of
the chain.sprocket-wheels, partly in section.
Fig. 6 is a side elevation of one of the chain
sprocket-wheels, a portion being broken away
50 to show the construction. Fig. 7 is a sec-
tional view of one of the conveyer-slats and
conveying-pins. Fig. 8 is a fragmentary viewshowing man ner of loading scrap-wheels. Fig.
9 is an elevation of wheel-bridging.
Like numerals ;of reference indicate the 5
same parts throughout the several figures, in
which- -.
1 is the conveyer, composed of the sides 2
and transverse 'braces or=supports 3, upon
which.are laid the longitudinal slides 4, Fig. 6o
3. The tops of said sides 2 and longitudinal
slides .4, are sheathed with iron. 5 indicates
the chain sprocket-wheels, journaled on shaf t
6. The upper shaft and sprocket-wheels are
keyed together, and said shaft extends some 65
distance xn either side of the sides 2 in order
to carry two.sprocket-wheels 7,.also keyed to
the shaft. The lower shaft 6 is secured in
movable journal-boxes, and attached to said
shaft on .the outer side of said boxes are two 70
tightening - rods 8, which extend through a
transverse brace 9, secured to the ends of the
.sides 2. The lower portions of said tighten-
ing - rods are threaded and after passing
through said brace nuts are threaded on,which 75
draws the lower sprockets 5 downwardly, thus
tightening the conveyer-chain 10.
By referring to Figs. 5 and 6 it will be seen
that the sprocket-wheels.are provided with
sprocket-teeth 11, in pairs, which do not ex- 8o
tend beyond the periphery of the wheels, but
are formed on the inner sides of the annular
flanges, which'flanges are formed by the an-
nular groove 12. A space the width of this
groove is left'between the teeth, while a con- 85
siderable portion of the flanges is cut away
between each pair of teeth, thereby forming
recesses 13, the depth of which is not as great
as the depth of the groove 12. In the bottom
of each of said recesses and..on either side of 90
the groove 12 is a smaller recess 14, the pur-
pose of which will be hereinafter fully de-
scribed.
10 indicates the conveyer-chain,to which are
secured the conveyer-slats 16. A T-headed 95
bolt 17 is passed through a horizontal link 18
of the conveyer-chain, and a nut 19 is thread-
ed on said bolt, after which said bolt is passed
through a slat 16, and a nut 21 is then thread-
ed on the end of 'said bolt. When the con- 100
veyer is in operation, the conveyer-chain
passes over the sprocket - wheels and every
horizontal or alternate link is carried in the
recesses 13, the teeth straddling the vertical
