BENJAMIN W. JOHNSON, OF BUNA, TEXAS.
LOG-CAR ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 554,342, dated February 11, 1896.
Applioation filed Jine 20, 1895. Serial No, 553,462, (No model,)To cll whom it nUay concern.
BeitknownthatI, BENJAMIN W. JOHNSON,
a citizen of the United States, residing at
Bnna, in the county of Jasper and State of
5 Texas, have invented a new and useful Log-
Car Attachment, of which the following is a
specification.
This invention relates to an improvement
in log-car attachments, and has for its object
io to provide, in connection with the bolsters or
bunks thereof, adjustable pins or standards
for engaging the lower tier of logs and pre-
venting their escape.
A further object of the invention is to pro-
15 vide a sway-bar socket in the form of a metal
plate or casting, adapted to be secured to the
inner face of the bolster of each truck for the
purpose of receiving and supporting the ends
of the ordinary sway-bar.
2o Other objects and advantages of the inven-
tion will appear in the course of the subjoined
description.
With the above ends in view the invention
consists in the combination, with a log-car
25 bolster or bunk having a vertical opening, of
a revoluble and vertically-adjustable pin or
standard mounted within said opening, and
means for elevating and lowering said pin or
standard and holding the same at the desired
30 adjustment.
The invention also consists in the combina-
tion, with such bolster or bunk, of a plate or
casting having formed integrally therewith a
laterally-projecting flange disposed in such
35 manner as to constitute a socket for the re-
ception of one end of a sway-bar.
The invention also consists in certain novel
features and details of construction and ar-
rangement of parts, as hereinafter fully de-
40 scribed, illustrated in the drawings, and
finally embodied in the claims.
In the accompanying drawings, Figure 1 is
a side elevation of a log-car with the improve-
ments shown applied thereto, and illustrating
45 the manner of supporting and holding a se-
ries of logs thereon. Fig. 2 is a perspective
view of one end of a bolster or bunk, showing
the stay pin or standard elevated in operative
position, and showing also the form of the
50 sway-bar socket-plate. Fig. 3 is a vertical
longitudinal section through one end of a
bolster or bunk in line with the stay pin orstandard. Fig. 4 is a vertical transverse sec-
tion in line with said pin or standard, taken
at right angles to Fig. 3. Fig. 5 is a topper- 55
spective view of the top plate which receives
the pin or standard. Fig. 6 is a bottom per-
spective view of said top plate. Fig. 7 is a
bottom plan view of the bottom plate through
which the pin or standard passes. Fig. 8 is 6o
a detail perspective view of the vertically-
movable pin or standard and the operating-
lever pivotally connected therewith.
Similar numerals of reference designate
corresponding parts in the several figures of 65
the drawings.
In the ordinary construction of log-cars a
spike is driven into each end of each bolster
or bunk, and the logs, as they are loaded upon
the car or unloaded therefrom, have to be 70
lifted over these spikes, an operation which
is not only laborious by reason of the great
weight of the logs, but dangerous to the men
handling the logs. It is also customary in
log-cars, as at present constructed, to mortise 75
the ends of the bolsters or bunks horizontally
for the reception of the ends of the sway-bars.
The sway-bar consists of a pole to which the
binding-chains which pass over and around
the logs are secured. Two of these bars are 80o
employed upon each car and are attached
thereto by passing the ends thereof through
such mortises in the ends of the bolsters or
bunks. In order to accomplish this, one end
of the sway-bar is hewed off sufficiently to 85
enable it to pass through the mortise in one
bolster to an extent which will enable the
other end to pass inside of the bolster at the
opposite end of the car and into the mortise
therein. This requires a great deal of time co
and labor, and the hewing of the ends of the
sway-bars results in weakening the latter to
such an extent that they are very easily
broken. In addition to this the mortises in
the ends of the bolsters or bunks are neces- 95
sarily large, thus weakening said bolsters so
that they soon split or break out and become
useless. It is to overcome the difficulties just
presented that the herein-described improve-
ments have been provided and which I will oo
now proceed to describe.
Referring to the accompanying drawings, 1
designates a log-car having the usual bolsters
or bunks 2 extending transversely thereof.
