be readily swung around from their sup-
porting position to permit the pivoted chock-
ing devices to swing downward. The sup-
porting plates or members extend beneath
5 the upper portions of the chocking devices
and receive the horizontal shoulders 11, as
clearly illustrated in Figs. 1 and 3 of the
drawing, and they are locked in such posi-
tion by means of hooks 141, arranged in se-
10 ries and mounted on the exterior of the bol-
ster at the side face opposite that at which
the strip 17 is arranged. The bills of the
hooks engage perforations 18 of the proxi-
mate ends of the supporting plates or mem-
15 bears, and the shanks of the hooks are pro-
vided with eyes 19, which are linked into
suitable eyes 20 of the bolster. The hook-
engaged ends of the supporting plates pro-
ject beyond the bolster, and when it is de-
20 sired to unload a wagon, the hook, which
extends through the supporting plate or
member and projecting slightly below the
lower face of the same, is knocked upward
out of engagement with the supporting plate
25 or member, and the latter is swung horizon-
tally away from the chocking member, which
swings downward and releases the load.
The chocking devices may be almost in-
stantly released to enable a wagon to be
30 quickly unloaded.
When loading a wagon, the skid is placed
against the end of the bolster and the farther
chocking device is arranged in operative po-
sition, the proximate chocking device being
35 arranged within the bolster out of the path
of the logs. After the load has been placed
on the wagon, the chocking devices at the
side where the wagon has been loaded, are
swung upward into engagement with the
40 load and are supported in such position by
the transverse plates or members.
The bolster is provided at the bottom of
the longitudinal space or ways with longi-
tudinal supporting strips 21, extending out-
45 warclly from the central bearing block 3 and
terminating short of the end spacing block
4 to form cleaning openings 22. The strips,
which are preferably constructed of wood
to render the bolster as light as possible, are
50 arranged to support the chocking devices,
so that they may be readily grasped by the
operator. The openings 22 enable any pieces
of bark, chips, and other accumulation to be
readily raked or scraped out of the longi-
55 tudinal spaces or ways to prevent such accu-
mulation from interfering with the chock-
ing devices. The outer ends 23 of the sup-
porting strips are beveled to facilitate the
removal of the bark and chips, and the bol-
60 ster is provided above the openings 22 with
transverse supporting pins 24, arranged to
receive the chocking devices when the latter
are at the limit of their outward adjustment.
The pins prevent the chocking devices from
65 dropping downwardly into the openings 22beyond the reach of the operator. The strip
17, which is provided with the sockets, is
preferably constructed of wood in order to
avoid materially increasing the weight of
the bolster. The pins extend a sufficient dis- e
tance into the sockets, and the bearing re-
cesses 7 of the sides of the bolster are of
sufficient depth to prevent any liability of
the chocking devices and their supporting
means from becoming lost unless the wagon
should upset.
Having thus fully described my inven-
tion, what I claim as new and desire to se-
cure by Letters Patent, is:-
1. The combination of a bolster having 8o
spaced side portions forming a longitudi-
nal opening and provided a t intervals with
bearings, a chocking device provided with
a pivot adapted to be arranged in the said
bearings, whereby the chocking device may
be adjusted along the bolster, and a support
arranged in the opening of the bolster and
located below the said bearings for limiting
the downward movement of the chocking
device to hold the same within reach in any o
adjustment of the said device.
2. The combination of a bolster having
spaced side portions, a pivoted chocking de-
vice mounted between the spaced side por-
tions of the bolster, a transverse supporting
plate or member bridging the space be-
tween and supported directly by the side
portions of the bolster and receiving and
supporting the chocking device, a pin
mounted on the bolster and connected with
the plate or member and forming a pivot
for the same, and means for securing the
plate or member in its supporting position.
3. The combination of a bolster having
spaced side portions, a pivoted chocking 105
device mounted between the side portions,
a plate or member extending across the
space between the side portions of the bol-
ster and receiving and supporting the chock-
ing device, a vertical pin connected with o
and forming a pivot for one end of the sup-
porting plate or member to enable the same
to swing horizontally away from its sup-
porting position, and a fastening device
detachably engaging the other end of the
plate or member for holding the same in
its supporting position.
4. The combination of a bolster having
spaced sides, each side being provided with
a series of duplicate bearings consisting of 120
recesses, which extend from the top part
way down the side, a chocking device fitting
in the space between the sides and having
pivots adapted to engage in any two of the
said recesses, said chocking device being re- 125
movable and insertible from the top, and a
locking device for the said chocking device.
5. The combination of a bolster open at
the top and provided at intervals with bear-
ings, a chocking device fitting in the open- 130
