I, JESSE HASKINS of the firm of Sam. Haskins & Bros., of 24 Old Street,
St. Lukes, in the County of Middlesex, Engineer, do hereby declare the nature of this
invention to be as follows
The object of the invention is to facilitate the raising and lowering of goods or
other matters in warehouses, hotels, private residences or other places.
axes
The apparatus consists mainly of a framework or supports for an axis or
on which is mounted a grooved or supporting pulley or pullies for the rope or
chain or connections for supporting the lifted receptacle or cage and the balance
weight or weights, bearings for same, and pulley wheel or hauling wheel over
which the hauling rope is passed. On the side of the hauling wheel is a flange
which encloses the periphery of a break wheel mounted on the framing.
The axis of the weight carrying pulley and hauling wheel is capable of rocking
in the direction of its length that is at a removable point between the weight
carrying pulley and the haulage wheel, this axis is supported slung from a cross
tie bar or support above and the shifting of this sling in a direction to or from
the load pulley increases or decreases the amount of leverage power exerted by the
baulage means to depress that end of the axis.
The extent of movement thus given is regulated by screw adjustment or in a like
manner.
The motion of the haulage wheel and the break wheel is made sympathetic in the
one direction-that for raising-by ratchet gearing.
The tilting of the axis by the haulage strain, the extent of which relatively to the
amount of load is adjustable by the shifting of the axial support, removes the
flange of the haulage wheel from the friction break wheel whilst its release imme-
diately is followed by their engagement, thus constituting a self sustaining lift
wherein the load or cage will be caught and retained at any point where haulage
ceases.
The rapid lowering of the cage can be effected by means of pressure on a lever
conveniently placed which relieves the flange wheel from pressure on the break wheel,
or instead of a lever, equivalent means of disengagement may be employed.
For heavy work the increase of power required may be provided for by increase of
parts or connection of bearing parts.

Improvements in Lift Apparatus for Raising and Lowering.
I JESSE HASKINS of the firm of Samuel Haskins & Bros., of 24 Old Street,
St. Luke's, in the County of Middlesex, 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 :-
The object of the invention is to facilitate the raising and lowering of goods or
other matters in warehouses, hotels, private residences or other places.
The apparatus consists mainly of a framework or supports for an axis or axes on
which is mounted a grooved or supporting pulley or pulleys for the rope or chain or
connections for supporting the lifted receptacle or cage and the balance weight or
weights, bearings for same and pulley wheel or hauling wheel over which the hauling

This axis carrying the supporting pulley cover which is passed the rope d carrying
the load, not shewn, is mounted towards one end in a bearing block e, and towards
the opposite end in another bearing block e¹, these bearing blocks move vertically in
guide-ways a² and as formed at the upper ends of the frames a at the opposite sides of
the apparatus, so that the axis bis caused to tilt on its centre of support formed by
the hinged slinging collars i, j. On the outer end of this axis is also mounted the
grooved wheel over which is passed the hauling rope g. On the inner face of the
wheel is forined the flange f¹, concentric to the wheel f, and within this flange f¹

page_text: is the wheel which by frictional contact with the inner surface of the flange fl
serves as a break. This wheel his mounted with capability of rotation on the boss /
projecting from the framing a (Fig. 9) and through this hollow boss the end of the
leverpasses.
The amount of movement of the bearing e in its guideway a³ and the con-
sequent extent of tilting of that end of the lover is controlled and adjusted to the
position of the supporting sling i, j by means of the screw a applied in the framing
above the guide way a³ and pressing on the upper side of the bearing e¹ and the
shifting of the collars of the sling along the bark and axis b to or from the

the flange from the frictional break wheel h, the extent of the strain being
adjustable, by the shifting of the axial sling i. j. as already explained, to the
amount of the load and permits the load to be raised, whilst upon release of the
haulage rope is immediately followed by frictional reengagement of the wheel h and
flange and suspension of the load at the point attained.
Rapid lowering of the cage is effected by hauling on the cord m connected to a
ring m attached to the end n³ of a lever n having mounted on its opposite end a
weight n said lever being capable of swinging on a fixed pin n¹ mounted on the
framing a as a pivot or fulcrum and in this lever n is formed another hole n² into
which passes a stud es fixed in and projecting from the tail e dependent from the
sliding bearing e carrying the one end of the axis the depression of the end n³ of
the lever a causing the end to be depressed and the wheel to, be freed from the
break wheel and to descend.
o is a guiding grooved pulley, rotating on the axis p carried adjustably in the
bearing provided for it in the frame a, to guide the rope d carrying the load whilst o
is a similar grooved pulley similarly mounted on the axis p' and bearing g', serving to
guide the rope carrying the counterweight.
For heavy work the increased power required may be attained by duplicating
parts.
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 :-
1. In a lift apparatus the combination with a break wheel of a haulage wheel
having its axis suspended on rocking centre arranged so as to be adjustable as to the
leverago exercised on the load wheel substantially as set forth.
2. In a lift apparatus the arrangement or combination and use of adjustable
sliding suspending bearings linked or hinged together as i, j, forming an adjustable
point of suspension for an axis carrying the haulage wheel or wheels, and the load
supporting wheel or wheels, sliding vertical bearings therefor, a break wheel to
cooperate with said haulage wheel, a lever for disconnecting the same for lowering, all
constructed and operating substantially as set forth.
3. The combination or arrangement and use of parts of lift apparatus substantially
as and for the purpose set forth.
