Improvement in Lawn Mowers.
I, JOHN BRAUN of No. 1615 N. 23rd Street, Philadelphia, Pennsylvania,
United States of America, Manufacturer of Lawn Mowers, 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 :-
My invention relates to improvements in lawn mowers, and consists of an
adjustably mounted grass receptacle also an adjustably mounted guard for the
cutter of the mower and further of a frame secured to the boxes or bearings of
the shaft of the running gear for attaching single trees to the mower.
My invention further consists of the combination and arrangement of parts as
hereinafter set forth.
In the accompanying drawing:-
--
Figure 1 represents a perspective view of a lawn mower embodying my
invention.
Figure 2 represents an end view of the grass receptacle thereof.
Figure 3 represents a partial view in perspective of one end of the cutter guard
of the mower.
Figure 4 represents a horizontal sectional view of the means for attaching the
cutter guard to the rear frame of the mower and
Figure 5 represents perspective views of detail portions of the adjusting
mechanism for the grass receptacle.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a lawn mower, the working parts of which, except as hereinafter
set forth, being of ordinary make or construction.
On the axle B of the running gear is mounted a grass receptacle C, consisting
of a box having its front, bottom and ends closed, and provided with an opening in
its rear adjacent to the cutter of the mower, so as to be adapted to receive the
grass as it is cut.
To the bottom of the said receptacle C and at or near each end are secured the
brackets D, which are provided with the downwardly extending legs E, so as to
be adapted to be seated between the flanges or ribs F of the collar G, which
latter are secured on said axle B. To adjust the collars, and thereby the brackets
and receptacle on said axle, each of the collars is split or divided on one side of
the axle, forming ends, each of which has an opening therein, through which
a headed screw-bolt H is passed, a nut J on said bolt tightening the collar on
the axle.
It will be seen that when the nut is loosened, the collar G may be easily moved,
either endwise or rotated on the axle, so that it may be placed in any position
desired for a bracket secured to the receptacle C. The collars when secured in
place on the axle afford a firm seat for the said receptacle, so that the latter
remains steadily fixed in place without moving thereon or may readily be detached
without removing the collars.
K designates a guard which is located behind the cutter, its ends being cut away
at L so that its frame M may form holding or bearing surfaces for the rotatable
pieces or journals N, each of which is mounted on a rear frame P of the machine,
by means of the screw bolt Q, a nut R locking the said bolt in place.
Each of the pieces N is provided with the limbs S and T, one of which engages
or comes directly in contact with the frame M and the other in contact with the
covering of the guard on said frame, as shown in Figure 4.
It will be seen that by loosening the nuts R, the guard K can be readily set

page_text: at different angles or positions, and then secured.thereat by tightening the nut on
the bolt.
To provide means for connecting singletrees to the running gear of the machine,
a frame U is employed; said frame consisting of a bar having a flattened main or
front portion V, with openings W therein for attachment of the singletrees and
limb portions X, the ends of which are inserted in sockets Y on the boxes Z of the
runuing gear, and secured therein by the pins A' passing through openings in the
ends of the limbs X: The frame U is readily secured in place, forming an
inexpensive and convenient means for the purpose designed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I déclare that what I
claim is :-
―
1st. A lawn mower having a grass receptacle adjustable on the axle of its
running gear, substantially as described.
2nd. A lawn mower having an adjustable guard for the cutter thereof substan-
tially as described.
3rd. In a lawn mower, a running gear axle, a collar adjustable thereon .and
adapted to be rigidly secured thereto, a bracket adapted to be seated on said
collar, and a grass receptacle connected with said bracket, said parts being com-
bined substantially as described.
4th. In a lawn mower, a split collar having flanges or ribs thereon, a bracket
with limbs adapted to be seated on said collar, and a grass receptacle connected
with said bracket, said parts being combined substantially as described.
5th. In a lawn mower, a cutter guard a journal or rotating piece adapted to be
secured to said guard and clamping means for said rotating piece, said parts being.
combined substantially as described.
6th. In a lawn mower, a rotatable piece or journal having limbs adapted to
embrace or hold a cutter guard and having a screw bolt therein on which it is
adapted to turn, and a nut for clamping said rotatable piece in place, said parts
being combined substantially as described.
7th. A lawn mower having an attaching frame consisting of a bar with a flat
main portion having openings, therein, and limbs adapted to enter sockets on boxes
of the running gear, substantially as and for the purpose set forth.
