I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and C Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of the invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
This invention relates to that class of carpet cleaning apparatus in which the
carpet is lifted or carried upward, and then thrown forcibly forward and downward,
within a rotating drum.
The said invention consists essentially in the employment of saddles for
supporting the lifting devices and limiting the extent of the motion thereof,
whereby there are obtained simplicity and strength of the cleaner, and effective
operation of the lifters, without the latter being liable to clog.
In the accompanying drawings.
Figure 1 represents a cross section of a carpet cleaner embodying my invention.
Figure 2 represents a perspective view of a detached portion thereof.
Similar letters of reference indicate corresponding parts in the two Figures.
A designates a drum, both the side and heads of which are formed of slats or
openwork, to permit the escape of dust, dirt, etc, which drum is mounted in a
suitable frame by means of gudgeons or journals so as to receive a rotating
motion.
Within the drum are situated the lifters or elevators B, which are composed of
suitable vanes or blades, extending parallel with the axis of the drum, and the
ends of which are freely fitted in saddles C, on the ends of the drum; these saddles
being arranged at the proper points to receive the ends of the lifters, and each
constructed of a double sector-shaped box or inclosure C¹, C³, meeting at the
narrow portion or end to form an inner neck D, the side walls of which constitute
a fulcrum on which the lifters may vibrate, as hereinafter more fully described.
The sectors C³, C, are unequal in length, and hence the neck or fulcrum D is
eccentric to the lifters in respect to their width.
It will be seen that when motion is imparted to the drum, the lifters are brought
successively in contact with the carpet within the drum, and raise the former until

page_text: they reach approximately the highest point, when the lifters turn or move from
one side of the saddles C to the other side thereof, the carpet being thrown forcibly
forward and downward, owing to the rotary motion of the drum and the force of
gravity, to the lower portion or bottom of the drum, thus causing the said carpet
to be beaten against the periphery thereof, and thereby become freed of dust
and dirt.
The flanges of the ends of the saddles act as supports for the lifters, and retain
them in position transversely thereof, while the side flanges of the saddles act as
stops to regulate the extent of the vibrating motion of the lifters, and inasmuch
as these purposes are effected without any fixed or rigid connection of the lifters,
a simple and very strong or durable structure is obtained, whilst the lifters operate
effectively and are not liable to clog in the saddles, due to the fact that the saddles
are kept free of dirt by means of the lifters.
In the example shown, the saddles are formed separate from the drum, and
properly connected therewith, but if desirable the saddle may be formed directly
on the drum.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me by my foreign Correspondent I wish it understood that I claim ;---
First. A rotating drum provided with a vibrating lifter and a saddle, substan-
tially as described, freely receiving the ends of the lifter, as stated.
Second. A saddle for the lifter of a carpet cleaner constructed of sector-shaped
pieces connected at their narrow ends, substantially as described.
Third. A saddle for the lifter of a carpet cleaner, constructed of double sector-
shape with flanged ends and sides, substantially as described.
Fourth. In a carpet cleaner, a rotary drum provided with saddles, substantially
as described, and lifters having their ends loosely fitted in the said saddles, sub-
stantially as and for the purpose set forth.
Fifth. In a carpet cleaner a rotary drum having saddles formed with side walls
and a narrow neck, substantially as described, secured to the ends of the drum, in
combination with lifters having their ends loosely fitted in said saddles, and
adapted to rock or vibrate on the walls thereof, substantially as, and for the
· purpose, set forth.
Sixth. A rotary drum provided with saddles C, having necks D and sector-
shaped parts C, C2, and the lifter B, the said saddles being secured to the ends of
the drum, and the lifters having their ends loosely fitted in said saddles, substan-
tially as, and for the purpose, set forth.
