page_text: I. ANSON TITUS, of National City. San Diego County, California, U.S.A.,
Inventor, do hereby declare the nature of this invention to be as follows:-
-
This invention has for its object the provision simple means whereby road
scrapers can be made to dump the contents of their receptacles when required.
By these my improvements, the receptacle of the scraper is swung. by suitable
pendant links, from the axle so that it can be rocked to discharge its contents.
At the rear of the receptacle two bars are arranged parallel and reciprocably
in guides. A hand-lever is pivoted near its lower end to the receptacle.
between the bars, and at points, on each side of the pivot it is pivoted to the
bars.
By moving the lever to one side the bars are projected outwardly in opposite
directions to engage the tyres of the wheels which, revolving, carry the receptacle
with them and discharge its contents. The ends of the bars are bevelled so that
they ride easily onto the tyres without being stopped by contact with the edge
or side of the felly.
A spring, connected to the lever and receptacle, respectively, returns the
former into its normal position when released.

I, ANSON TITUS, of National City, San Diego County, California, U.S.A.,
Inventor, do hereby declare the nature of this invention, and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
The object of my invention is to provide a wheeled road-scraper with a simple,
durable, and economic, and readily applied dumping attachment.
Another object of the invention is to so construct the attachment that it may
be brought to an engagement with the wheels of the machine and be auto-
matically operated by the said wheels.
The invention consists in the novel construction and combination of the
several parts, as will be hereinafter fully set forth, and pointed out in the claims.

page_text: Reference is to be had to the accompanying drawings, forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in all the figures.
Figure 1 is a side elevation of a road scraper having the improvement applied.
Fig. 2 is a rear elevation of the said scraper and Fig. 3 is a horizontal section
through the rear portion of the scraper, taken substantially on the line 3-3 of
Fig. 2.
A represents an arch axle or crank-axle, at the ends of which supporting
wheels B are mounted to loosely turn, and C represents a scoop of any approved
construction. The scoop is supported from the crank arm of the axle A by
means of hangers 10. secured to its sides preferably at the centre.
D represents a pole or tongue provided with arms 11 attached at its sides.
which arms extend one at each side of the forward end of the scoop C, having
bearing near their inner ends against pins 12, secured to the side faces of the
scoop. The arms 11 of the tongue or pole are pivotally attached to the yoke
frame 13, which extends rearwardly at the sides of the scoop and across the
upper portion of the scoop at the rear, the said yoke-frame 13 being attached to
the spindle portions of the axle A by means of links 15 or their equivalents, as
shewn best in Fig. 2. A handle 14 is attached to the rear central portion of
the yoke-frame 13. by means of which handle the scoop may be raised from the
ground when it has received its load. Handles 16 are likewise provided for the
scoop, being attached at each side of the rear portion of the scoop, and a lever 17
is pivoted to the central rear portion of the yoke frame 13, the lever being
provided with a hook section 18. adapted to engage with a lug 19 on the rear of
the scoop and hold the scoop in its upper position. All the parts above
enumerated are of the usual construction.
•
The attachment to the scoop consists of two sliding bars 20 and 21. placed
one above the other at the rear of the scoop near the bottom, and the bars 20
and 21 have end movement in guides 22, secured to the back of the scoop, the
bars being supported by pins 23 passed through the central portion of the guides
or like devices. A lever 24 having a fulcrum 25ª upon the scoop. is pivotally
connected with both the upper and lower sliding bars 20 and 21 by means of
pins 25 and 26, and when the lever is moved laterally one of the sliding bars
will be given end movement in direction of the right-hand side of the machine
and the other sliding bar will be given movement in direction of the left-hand
side of the machine. The upper sliding bar 20 is of such length that one of its
ends will extend beyond the outer face of the right-hand wheel B, and this end
of the sliding bar 20 is provided with a forwardly extending arm 20ª, adapted
for engagement with the outer-face of the right-hand wheel. A second for-
wardly extending arm 20h is formed at the left hand side of the sliding bar 20.
and the arm 20 is adapted for engagement with the inside of the left hand
wheel when the arm 20° engages with the outer face of the right-hand wheel.
The lower sliding har 21 is carried beyond the outer face of the left-hand
wheel B and at that end is provided with a forwardly extending arm 21ª arranged
for engagement with the outer face of the said left-hand wheel, while at the
opposite end of the sliding bar 21 a forwardly extending arm 21b is formed.
arranged for engagement with the inner face of the right-hand wheel when the
opposite arm 21ª engages the outer face of the left-hand wheel.
When the locking lever 17 is disengaged from the rear of the scoop and the
shifting-lever 24 is manipulated to bring the forwardly extending arms of the
sliding bars 20 and 21 in engagement with the wheels as the machine advances,
the wheels will carry up the rear end of the scoop and will cause its load io be
dumped.
The dumping bars 20 and 21 are prevented from engaging with the wheels
when not wanted by attaching a spring 27 to the lever 24 and the upper edge of
the scoop, and the spring is prevented from pulling the lever too far to the right
by a stop 27 located upon the scoop,

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
(1) In a wheeled scraper, the combination with the wheels and a piroted
scoop, of bars mounted to slide at the rear end of the scoop, the bars being
arranged for clamping engagement with the said wheels, and means for carrying
the bars to and from engagement with the wheels, as specified.
(2) In a road scraper, the combination, with the wheels of the scraper and a
scoop, of bars mounted to slide at the rear end portion of the scraper, the bars
having their ends arranged for clamping engagement with the wheels of the
scraper, and a lever connected with both bars and arranged to simultaneously
move the bars in opposite directions, as set forth.
(3) In a road scraper, the combination with the wheels of the scraper and a
scoop, of bars held to slide at the rear lower portion of the scoop, the bars being
provided with forwardly extending arms at their extremities, an arm of one bar
being arranged for engagement with the outer face of the right hand wheel and
the opposite arm for simultaneous engagement with the inner face of the left-
hand wheel, the arms of the other bar being arranged for simultaneous engage-
ment one with the outer face of the left-hand wheel and the other with the
inner face of the right-hand wheel, and a lever pivotally connected with both
bars, and arranged to move the bars simultaneously in opposite directions, as
described.
