Improvements in Lawn Mowers.
Year: 1895

page_text: I, JAMES EDWARD RANSOME, of Orwell Works, Ipswich, in the County of
Suffolk, Engineer, do hereby declare the nature of this invention to be as
follows.-
The handles of lawn mowers are usually hxed to the frame of the machine and
consequently when the machine runs over haid or 1ough ground an unpleasant
biation is transmitted to the hands of the user. To avoid this inconvenience and
also to lessen the jar on the machine itself the handle bais are, according to this
invention, connected with the fiame by joints which permit the handles to play.
Springs are inter posed between the fiame and the handle bars so that the downward
pressure which the workman exerts on the handles is transmitted to the frame
through the spings. The independent movement of the handles is limited by
stops Preferably a coiled spring is used, one on either side of the machine, it is
interposed between the frame and the handle bar and a bolt passing through the
whole limits the movement. These bolts take the side stiain when turning the
machine by the handles.
O the machine may be made with two frames, an inner and an outer, jointed
together in fiont where the axis of the spiral cutter passes through or near thei eto,
and having springs inter posed between the two frames at the back of the machine.
The inner frame will carry the handles, the front rollers and the cutters, whilst the
outer frame carries the diving oller and the gear which transmits the rotary
motion of this roller to the pinion on the axis of the spiral cutter.

Improvements in Lawn Mowers.
I, JAMES EDWARD RANSOME, of Orwell Works, Ipswich, in the County of
Suffolk, Engineer, 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
This invention cousists in means for lessening the vibration which is transmitted
to the hands of the user, and also to lessen the Jai on the machine itself when the
machine is in work and especially when it runs over hard or rough ground.
One method in carrying out my invention is shown on the accompanying drawings,
Figures 1 and 2, Figure 1 being a side elevation of part of a lawn mower and
Figure 2 is an end view partly in section on the line X Y Figure 1.
In Figure 1, A 18 the handle bar, B is the main fiame of the machine, C is the
Joint where the bar A is connected with the frame B.
On the frame B is a guide bracket D; another bracket E 18 carried by the
handle bar A; between these two brackets is interposed a steel coiled spring F,
but which may be any other forin of spring or elastic material. The guide bracket D
A bolt &
acts as a side guide to the bracket E and thus to the handle bar A.

page_text: passing through the bracket D and over the top of the 'Handle bar A lunits the
vertical movement of the latter. If necessary provision can be made for regulating
the play of the handle bar A and spring F by a vertical adjustment at the top.
Only the left-hand side of the fiamd and handles is described and shown, but the
other side is arranged in the same manner
The second method for carrying out my invention is shown by Figures 3 and 4,
Figure 3 being a side elevation and Figure 4 a section on line V W.
B is an inner finme carrying the cutting bariel H, the bottom blade F, the grass
box supports K, the front supporting tolls L and the handle bars A.
M is an outer frame jointed at or near the axis of the cutting barrel II carrying
the diving roller N and the gear wheels 000, the Intter transmitting the
notary motion between the driving 1oller N and the pinon P fixed on the axis of
the cutting barrel' H.
Between these two frames is placed preferably a coiled sping F To limit the
vertical movement of the frame B and with it the handle bars A, I fix a blacket D
to the frame M. If necessary a set screw at the top can be used for adjustment.
Having now particularly described and ascertamed the nature of my said mven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The interposition of a spring between the frame of a lawn mower and the
bandles to reduce the vibration, substantially as described.
2. Making a lawn mower with two separate frames jointed at or near the axis of
the cutting cylinder, one part carrying the cutting cylinder and handles and the
other part the roller and diving geaning, and introducing a spring at the rear
between the two frames to reduce the vibration substantially as described
