ISAAC O. MEDDOWS, OF BONHAM, TEXAS.
IMPROVEMENT IN RUNNING-GEARS FOR VEHICLES.
Specification forming part of Letters Patent No. 136,331, dated February 25, 1873.To all whom it may concern:
Be it known that I, IsAAc O. MEDDOWS, of
Bonham, in the county of Fannin and State of
Texas, have invented certain new and useful
Improvements in Gearing for Road-Wagons,
Carriages, &c., of which the following is a
specification:
This invention relates to the mode of con-
structing the gearing of road-wagons, car-
riages, &c.; and it consists in forming the
head-block in two pieces, with a central eye or
opening for the passage of the axle; a groove
for the reception of the king-bolt of the rock-
in g bolster; and wrought-iron brackets or loops
for the attach ment of the coupling-pole, tongue,
&c.; also, in friction-boxes for the axles, formed
in two parts, the upper having a key or bear-
ing for the journals of a friction-roller placed
within the box over the axle, and the lower
part of the box having a key or bearing placed
immediately beneath the axle; the whole form-
ing friction-boxes, which are firmly bolted to
the bolsters by means of wrought-iron bands
which encircle the boxes; and in further de-
tails of construction hereinafter more fully set
forth.
In the drawing, Figure 1 is a top or plan
view of the gearing embodying my invention.
Fig. 2 is a side view of the same. Fig. 3 rep-
resents an end view. Figs. 4, 5, 6, 7, 8, and
9 are detached views of my improvements in
wagons.
Like letters of reference indicate correspond-
ing parts.
The letters A A' represent the two parts
forming the head-block. They are of cast-
iron and of similar construction, so that when
brought together a central eye or opening is
formed for the passage of the axle-tree, and a
groove in the upper part of the block is left for
the reception of the king-bolt a. B B' repre-
sent wrought-iron brackets or loops bolted to
the front and rear of the head-block for attach-
ing the tongue and coupling. The sections of
the head-block are extended downward, form-
ing two arms or projections, b b', which em-
brace the said bolster, and form the means for
securing the head-block upon the sand-bolster
C, by bolts and nuts or otherwise. D D' rep-
resent the two sections forming the friction-
box for the axles, the sections being confined
together by a wrought-iron band, E, passingaround the entire box and fastened with bolts
to the bolster C. d d' represent what I term
"friction-keys" or bearing-surfaces, composed
of cast-steel. The one, d, in the upper section,
D, of the box, is made of such a size as will
accommodate the journal f of a friction-roller,
F; the lower one, d', must be of such size as
will admit of free movement of the axle-tree
H. The upper section of the box D is by far
the larger and stronger portion, and is re-
cessed, as shown in Figs. 6 and 8, for the re-
ception of the friction-roller F. The lower sec-
tion D' is little more than a shell for contain-
ing the key or friction-surface d', this construe-
tion being necessary, as the upper portion has
to bear the weight of the load and the jar of
travel. e are loops or brackets bolted to the
band E as fastenings for the guide-braces of
the tongue.
The construction of the several friction-boxes
and their relation to the axle-trees are similar,
and such as above described. Their mode of
attachment to the bolster-coupling tongue I
will now proceed to describe.
The head-block and the two friction-boxes
of the forward axle-tree are placed over the
sand-bolster C, and secured thereto by means
of the bolts and nuts or other suitable devices
passing through the downwardly- projecting
portions b b' of the head-block and bands E E
which surround the friction-boxes. The tongue
is connected to the head-block by a wrought-
iron strap passing around the end of the tongue
and through the loop B on the head-block.
Across the tongue, at right angles to the same,
is arranged a cross-bar; I, which connects with
the guide-braces g g, said guide-braces being
secured at one end to the loops e of the band
E, and at the other end to the tongue in any
suitable manner. K, Figs. 1 and 2, represents
the rocking bolster, which is provided with
circle-bars k, (shown in dotted lines,) placed
underneath the bolster, immediately over the
friction-boxes, and secured to the bolster by
braces fastened nearthe ends thereof. L repre-
sents the coupling or reach secured to the head-
block by a wrought-iron strap passing through
the loop or bracket B', and having a stay or
brace, 1, extending from the coupling to the
sand-bolster C. M represents the rear bolster,
whic' is placed over the friction-boxes and
axle- ree, and connected to the boxes by being
