when said arms are moved, as they neces-
sarily must be, in the same direction, both
catches will be released.
The operation will now.be readily under-
5 stood. Assuming that the bowl has been
loaded in the usual manner by lowering the
same, raising the handle and moving the
scraper forward until a sufficient amount of
dirt has been forced into the bowl, and that
io the same has been transported to the place
for dumping, when it is desired to dump, it
is only necessary for the attendant to move
the arms IH to one side and release the catches
G, thus permitting the rear section to swing
r5 down by its own weight and the weight of
the contained dirt, dumping the dirt con-
tained therein, and if the forward movement
of the scraper is continued in the construc-
tion illustrated, causing the forward edge to
20 be depressed and the scraper-bowl tobe turned
entirely over in the ordinary manner inci-
dent to the use of all scrapers of this charac-
ter.
It is obvious that while I have shown the
25 present improvement as applied to a wheel-
scraper of particular const ruction, the divided
bowl may be applied to any other form of
scraper in which a bowl is employed adapted
to transport the dirt from one place to an-
30 other, and to be emptied or dumped by the
operator or attendant without departing from
the spirit of my invention; and it is further
obvious that in the use of a scraper con-
structed in accordance with this invention it
35 is not essential that the scraper-bowl should
be turned entirely over, as the inclination
given the two sections may be sufficient to
dump all the contained dirt; but it is desir-
able that the whole bowl should turn over,
40 inasmuch as by so doing the rear section is
caused to automatically assume its normal
- closed position by gravity without the neces-
sity of any action on the part of the attend-
ant, as will be readily understood by refer-
45 ence to Fig. 2.
Having thus described my invention, what I
claim as new is--1. In a scraper, the combination, with the
bowl for transporting the dirt, of the rear
bottom section hinged at the rear end thereto 50
and adapted to be swung down to discharge
the dirt, substantially as described.
2. In a scraper, the combination, with the
divided scraper-bowl having the rear section
hinged at the rear end thereto and adapted 55
to be swung down for dumping the dirt, of
the catches for holdingsaid section elevated,
substantially as described.
3. In a scraper, the combination, with the
bowl for transporting the dirt, of the rear 6o
bottom section hinged thereto at the rear end
and adapted to be swung down to discharge
the dirt, substantially as described.
4. In a scraper, the combination, with a di-
vided scraper-bowl having the rear section 65
hinged thereto at the rear end for dumping
the dirt and tilting the bowl, of the catches for
holding the said section elevated, substan-
tially as described.
5. In a wheel-scraper, the combination,with 70
the cranked axle and the bowl pivotally con-
nected thereto, of the rear section of the bowl
hinged thereto for dumping the contained
dirt, substantially as described.
6. In a wheel-scraper,thecombination,with 75
the axle and the reversible bowl connected
thereto and adapted to be reversed to dump
the load, of the rear section pivoted to the
bowl at the rear end and adapted to swing
down to cause said bowl to be tilted, substan- 80o
tially as described.
7. In a scraper, the combination, with the
divided scraper-bowl having the rear section
hinged thereto for dumping the dirt, of the
catches for holding said section elevated, and 85
the arms pivoted on one side in front of the
catch and on the opposite side in rear of the
catch and connected together for simulta-
neously releasing said catches, substantially
as described.
