Year: 1879

page_text: LETTERS PATENT to Henry Crowley, of Manchester, in the County of
Lancaster, Engineer for the Invention of "IMPROVEMENTS IN HORSE GEAR
FOR OBTAINING MOTIVE POWER." A communication from abroad by Ivar G.
Hallström, of Köping, in the Kingdom of Sweden.
Sealed the 18th November 1879, and dated the 3rd September 1879.
PROVISIONAL SPECIFICATION left by the said Henry Crowley at the Office
of the Commissioners of Patents on the 3rd September 1879.
HENRY CROWLEY, of Manchester, in the County of Lancaster, Engineer.
"IMPROVEMENTS IN HORSE GEAR FOR OBTAINING MOTIVE POWER." A communi-
cation from abroad by Ivar G. Hallström, of Köping, in the Kingdom of Sweden.
This improved horse gear consists of a large stationary bevel wheel which is
supported on brackets fixed to the ground. In the centre of this wheel is an
upright axle, on which is a mitre wheel and a bevel wheel, and above the large.
bevel wheel is a frame in which are bearings for a horizontal shaft on which is a
pinion gearing into the large bevel wheel, and a mitre wheel gearing into the mitre
wheel on the upright shaft. The poles to which the horses are connected are bolted
to the frame above referred to, and as the horses go round the bevel wheel on the
upright shaft gives motion to a pinion on the shaft connected to the machine to be
driven.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Crowley in the Great Seal Patent Office on the 3rd March
1880.

page_text: bevel wheel is a frame in which are bearings for a horizontal shaft on which is a
pinion gearing into the large bevel wheel, and a mitre wheel gearing into the mitre
wheel on the upright shaft. The poles to which the horse is connected are bolted
to the frame above referred to, and as the horse goes round the bevel wheel on the
upright shaft gives motion to a pinion on the shaft connected to the machine to be
driven.
And in order that the Invention may be fully understood and readily carried
into effect, I will describe the accompanying Sheet of Drawings, reference being had
to the figures and letters marked thereon. Fig. 1 is a longitudinal section; Fig. 2
is a front elevation, and Fig. 3 is a plan of the improved horse gear. a is a large
stationary bevel wheel with six arms b; the wheel has snugs with bolt holes to
bolt it to three wooden supports c, as shewn in the Drawing, the supports c rest
on the ground, and are fastened down by stakes or otherwise; e is a shaft or stud
fixed to the centre boss of the bevel wheel a; fis a cast iron frame which moves
round this centre; is the bearing of the frame f; and v is a washer which retains
it in its place on e; g, g, are the horse shafts or poles fastened by cramps d to the
frame f; on the frame fare two bearings h and 2, in which the horizontal shaft k
revolves; is a bevel pinion keyed on the shaft k and gearing into the bevel
wheel a;, m is a mitre wheel keyed on the shaft k which drives the mitre wheel n,
cast with the bevel wheel n!; 'the bevel wheel n¹ drives the bevel pinion o keyed
on the shaft p, which transmits the power to the machinery to be driven; 8 is a
check nut at the end of the bearing i, and y and z are two rollers or bowls which
revolve on studs fixed to the brackets f' cast on to the frame f, which rollers or
bowls bear against the under side of the rim of the wheel a and prevent the bevel
pinion from being lifted out of gear with the wheel a:
The mode of operation is as follows:-When the shafts are drawn round by
the horses the frame f carries round the bevel pinion 1, the teeth, of which gear into
the teeth of the stationary bevel wheel a, the pinion is thus caused to revolve and
communicates motion through the shaft k and the mitre wheel m to the mitre
wheel n, which, through the bevel wheel n¹, bevel pinion o, and shaft p, transmits
the power to the machinery to be driven.
Having thus stated the nature of the Invention communicated to me by Ivar G.
Hallström, of Köping, in the Kingdom of Sweden, and described the manner of
performing the same, I declare that I claim,--
First. The use of the stationary main bevel driving wheel a as shewn and
described
Secondly. The construction of the frame and the application of the rollers or
bowls y and z, as shewn and described; and,
Thirdly. The combination and arrangement of the horse gearing, shewn and
described, for obtaining motive power.
In witness whereof, I, the said Henry Crowley, have hereunto set my hand
and seal, this Second day of March One thousand eight hundred and eighty.
