BENJAMIN F. YOUNG, OF LEAVITT, TEXAS.
TRACK-LEVEL.Specification of Letters Patent.
Patented Aug. 25, 1908.
Application filed April 19, 1907. Serial No. 369,110.
To all whom it may concern:
Be it known that I, BENJAMIN F. YOUNG,
a citizen of the United States, residing at
Leavitt, in the county of Haskell, State of
5 Texas, have invented certain new and useful
Improvements in Track-Levels; and I do
hereby declare the following to be a full,
clear, and exact description of the invention,
such as will enable others skilled in the art to
10 which it appertains to make and use the
same.
This invention relates to track leveling in-
struments and has for its. object to provide a
leveling instrument of this class which may
15 be moved over a section of track to deter-
mine irregularities in the roadbed, the rise
and fall of the track, and the gage of the
rails.
In carrying out my invention I employ a'
20 truck carrying indicating device for indicat-
ing the rise and fall of the track and for de-
termining irregularities in the roadbed,
means for indicating the distance traveled
which means can of course be used to deter-
25 mine the extent of any rise or fall in the track
or roadbed and also the extent of any irregu-
larities. The truck furthermore includes
standards which are hinged and are connect-
ed by telescopic rods one of which is cali-
so brated so that any deviation from the stand-
ard gags of the track rails may be deter-
mined. .
In the accompanying drawings, Figure 1 is
a side elevation of the instrument, Fig. 2 is a1
35 rear elevation thereof, and, Fig. 3 is a detail
view of one of the leveling devices employed
in connection therewith.
In the drawings there. is shown a pair of
track rails 5 upon which the instrument em-
40 bodying my invention .is designed to travel.
The said instrument is in the form of a truck
including a top 6 supported by front and rear
pairs of standards 7 and 8 respectively at the
lower ends of which are journaled wheels 9
45 which travel upon the said track rails. The
rear pair of standards 8 are formed in hinged
sections as indicated at 10 and the movable
sections of these standards are connected in
a manner .which will now be described. A
50 sleeve 11 is formed integral with one mem-
ber 8 and projects inwardly past the middle
of the truck and a rod 12 projects inwardly'
from the other of the members 8 and is tele-
scopically received in the sleeve 11 and isprovided with calibrations 13. A set screw 55
14 is engaged through the sleeve member 11
adjacent its inner end and is adapted to im-
pinge against the rod 12 to hold the movable
sections of the standards in spread relation
and at a degree corresponding to the stand- 60
ard gage of track it being understood that
any deviation from this standard gage will
cause the rear wheels. either to bind or to
tend to leave the track rails.
In order that the irregularities in the road- 65
bed may be indicated, I have 'provided at the
rear end of the machine a calibrated dial 15
upon the face of which is pivoted a pointer
or indicator 16 which is weighted at its lower
end as indicated by the numeral 17, this 70
weighted lower end of the indicator serving
to normally hold the same in vertical posi-
tion and in order that any rise and fall in the
grade of the roadbed may be-determined I
have provided a similar indicating device 18 75
upon one side of the truck substantially at
the middle thereof. To further aid in deter-
mining irregularities in the roadbed I have
provided upon the truck at its- rear end a
spirit level 19. .80
In order that the distance traveled may be
determined, I have provided upon one of the
wheels 9 at the rear end of the truck an inte-
gral shaft 20 carrying a sprocket gear 21 over
which passes a sprocket chain 22. The 85
sprocket chain also passes over a sprocket
gear 23 rotatably mounted upon a stub shaft
24 and the said sprocket 23 has formed inte-
gral with it a finger 25 which is adapted to
contact, at each revolution of the sprocket, 90
with a spur wheel 26 which forms a portion
of an indicator 27 for indicating the distance
traveled 'by the truck. . I also preferably
mount upon the top of the truck.a surveyor's
level 28. 95
What is claimed is:-
1. A track gage comprising a body, sup-
porting sides hinged to the body and includ-
. ing standards, track wheels journale~d at the
lower ends of thestandards, an inwardly pro- 100
jecting sleeve member carried by one stand-
ard, and a rod carried by the opposing stand-
ard and received in said sleeve, the rod being
provided with scale marks.
2. A track gage comprising a body, sup- 105
porting sides hinged to the body and incud-
ing standards, track wheels journaled at the
lower ends of the standards, an inwardly pro-No. 897,045.
