PROVISIONAL SPECIFICATION. .
Improvements in Machinery for Sweeping and Conveying Away
Refuse from Streets, Roadways, and other Places.
WILLIAM MARCH 32 St. Mary Axe in the City of London Engineer do hereby
declare the nature of my invention for IMPROVEMENTS IN MACHINERY FOR SWEEPING
& CONVEYING AWAY REFUSE FROM STREETS, ROADWAYS & OTHER PLACES to be as
follows:-
My invention relates to improvements upon the Machinery patented by me
under number 91 & dated the 1st of January 1884, & consists of a
revolving broom placed in front of the elevator & on the near side of the
machine for the purpose of sweeping the channels of the roads. The broom is
placed at such an angle that it shall when revolving convey the sweepings under
the elevator case. This is accomplished in the following manner:
'A grooved pulley or chain wheel is keyed on to the short shaft of the elevator lever
pinion. From each side of this pulley or chain wheel & resting & centered upon the
pinion shaft springs the arm of a frame which extends forward & supports in suitable
bearings at their respective ends the shaft of the revolving brush. On to one end of
this shaft is keyed another grooved pulley or chain wheel for communicating through
rope or chain the revolving motion.
If grooved pullies are used the grooves are made V shape so as to grip the steel
wire rope which we use. The
rope is directed from the driver to the driven pulley by
means of two or more small grooved pullies, one of which is made to rise & fall for
regulating the tightening of the rope.
For the purpose of regulating the pressure of the revolving broom upon the road it
is suspended from the short end of a lever, the fulcrum of which is fastened to the
elevator case & the long, or handle, end is prevented from rising too high by a
spiral spring which is connected to an eyebolt which passes freely through the frame
of the Machine.
On to the eyebolt is screwed a nut which bears against the under part of the frame.
By screwing up this nut the spiral spring is stretched & the pressure of the broom
upon the road regulated accordingly.
Instead of using chains as we now do for working the brushes & buckets of our
aforesaid machine we apply steel wire ropes & V grooved pullies as hereinbefore
described in reference to the revolving broom.

COMPLETE SPECIFICATION.
Improvements in Machinery for Sweeping and Conveying Away
Refuse from Streets, Roadways, and other Places.
I WILLIAM MARCH of 32, St. Mary Axe, in the City of London, Engineer, do heroby
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 certain improvements upon the subject matter of the
Specification under Letters Patent No. 91, dated the 1st day of January 1884, granted
to me and consists :-(1), of a revolving broom or brush placed in front of the elevator
and on the " near (or left hand) side of the machine for the purpose of sweeping the
channels or gutters of the roads or ways; and, (2), the mounting of the said broom
or brush in, its frame and the means for driving and adjusting the same, and the
fitting in connection with my.aforesaid patented apparatus.
--

page_text: In order that the said Invention may be well understood I have hereunto annexed
a sheet of drawings illustrative thereof wherein;-Fig. 1 is a side view of the con-
struction embodying the improvements with so much of the old machine as is
necessary for purpose of illustration. Fig. 2.is a plan of Fig. 1.
The parts of my old construction of machinery as shown on the drawings are
lettered for purpose of reference as follows, vizt. A, is the elevator case; A', is the
elevator lever pinion; B, is the frame of the machine; C, is the spur ring bolted to
the spokes of the road wheel for giving off motion to the brushes and gearing.
The side broom or brush a, is placed in front of the elevator case A, and on the side
of the machine and is placed and mounted at an angle as shown so that it shall when
revolving convey the sweepings under the elevator case A.
I would here remark that I prefer to employ and do employ with the brush a and
the frame band mounting of same, the chain gear specified for under my Provisional
Specification filed on application for Patent herein, as distinguished from the grooved
pulleys and steel wire rope, as driving means for the shaftings and brush a.
I carry this Invention out as follows:-
.The chain wheel C₁
is keyed on the short shaft d, of the elevator lever pinion A.
From each side of the chain wheel c, and resting and centred upon the pinion shaft d,
springs the arms 1, of the iron frame b, which said frame extends forward and
supports in suitable bearings g, g', at their respective ends the shaft a', of the revolving
side brush a. On to the end g, of this brush shaft a¹, is keyed another chain wheel A, for
communicating through a counter shaft i, chain-wheels i, and chains, the revolving
motion.
For the purpose of regulating the pressure of the revolving broom or brush a, upon
the road it is suspended from the short end of a lever k, the fulcrum 1, of which is
fastened to the elevator case A, and the long or handle end of the lever is prevented
from rising too high by means of a spring m, which is connected to an eye bolt m³,
which passes freely through the frame B, of the machine.
.On to the eye bolt is screwed nuts m³, which bear against the upper and under
parts of the framing B.
.By turning these nuts m², the spring will be put in tension and the pressure
of the broom or brush a upon the road will be regulated accordingly.
The chain wheels h and i, on the shafts a', and i, respectively are not keyed
rigidly on the shafts but are secured by a centre pin which will allow of the said
chain wheels to have a wobbling" or side-wise motion in addition to the motion
around along with the shafts thereof, thus allowing of the employment of chain
driving gear upon shafts the centre lines whereof are out of parallelism relatively
to each other. The detail of this mounting of the chain wheels for the purpose may
form the subject of further application for Patent by me.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
First In sweeping apparatus as herein described the side brush a, mounted and
operating as and for the purpose herein setforth.
Secondly The frame of the side brush a with the shafts and gearing mounted and
operating as and for the purpose herein setforth.
Thirdly-In apparatus or machinery for sweeping and conveying away refuse
from streets road-ways and other places the combination of the side-brush a, the frame
therefor, with the chain-wheels and counter shafts for communicating motion to the
said brush a and constituting my improved apparatus constructed and operating as
and for the purpose herein setforth.
