Complete Specification Left, 1st June, 1891-Accepted, 11th July, 1891
PROVISIONAL SPECIFICATION.
An Improved Hub Wrench.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Melville Beach, of Ashton, Illinois, U.S.A.
Inventor) to be as follows:-
This invention relates to a new and useful device for removing nuts from the
hubs of carriage wheels; and which consists of two semi-circular pieces of metal,
which are pivoted together intermediate their ends, and terminate at their inner ends
in laterally disposed jaws. One of said members terminates at its outer and in a
threaded and perforated head, and the opposite member at its corresponding end,
in a transverse head, perforated at its opposite ends, and at an angle to each other.
Suitable binding screws are mounted in the perforations, and are adapted to clamp
the wrench to the band of the hub. In this position the inner ends of the curved
piece of metal which form the laterally disposed nut-receiving jaws, bear upon and
grip the nut, which can be removed by turning the wrench.
Dated this 30th day of August. 1890.

COMPLETE SPECIFICATION.
An Improved Hub Wrench.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Melville Beach, of Ashton, Illinois, U.S.A.
Inventor,) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention has relation to hub-wrenches, and among the objects in view are
to provide an exceedingly simple and powerful wrench adapted for clamping and
rigidly connecting the hub-band of a wheel with the axle-nut, whereby said wheel
may be removed and replaced simultaneously with the nut for the purpose of
oiling, cleaning, or repairing the bearing.
With the above general objects in view the invention consists in certain features
of construction, hereinafter specified, and particularly pointed out in the claims.
In the drawings,
Figure 1 is a transverse section of a hub showing its axle, a wrench constructed
in accordance with my invention being applied thereto and shown in side
elevation.
Fig. 2 is a perspective view of the wrench in detail.
Fig. 3 is a perspective view, in detail, of the binding member.
Fig. 4 is a similar view, in detail, of the opposite member.
In practising my invention, I construct the wrench of two opposite sections or
members, which are of substantially semicircular shape, and intermediate their ends
are pivoted.
1 represents the binding-section, and through the two is passed a pivot-bolt 3.
The adjacent faces of the two sections are perfectly plain where they have contact
with each other, so as to permit them to slide readily one upon the other. The
inner ends of the sections are provided with transverse jaws 4, the inner sides of
[Price 8d.1

page_text: which are provided with recesses 5, which receive the upper edges of the opposite
section, and thus serve to maintain said sections in sliding contact with each other.
The outer ends of the soction 1 terminate in a perforated head 6, the perforation
being threaded, and in the same is mounted a binding-screw 8, the inner end of
which projects through the opposite side of the perforation and is provided with a
loose washer 9, which may or may not be provided with a fell or other covering 10.
The outer end of the opposite member is provided with a laterally-disposed
head 11, the opposite extremities of which are provided with threaded openings 12,
arranged at an angle with relation to each other, and in the openings are mounted
set-screws 13, having at their inner ends loose washers 14, covered or not by
pads 15.
16 designates the hub of the wheel; 17, the axle: 18, the mut; and 20, the hub
band. To apply the wrench, the outer ends of the members are introduced over
the hub-band and the inner jaws over the axle-nut, and said members are adjusted
to a proper relative position with regard to the nut and the diameter of the hub-
band through the medium of the binding-screws 13. After such adjustment the
screw 8 is manipulated so as to tightly bind upon the hub-band, and in so doing
the outer ends of the members are laterally spread and the inner ends or jaws
contracted and clamped upon the nut. It will now be apparent that both the nut
and the hub are rigidly connected, and by using the wheel as a leverage and
rotating to the rear the nut is removed from the axle, which latter may be cleaned,
oiled, repaired, or otherwise attended to, and the wheel replaced by simply
introducing the hub over the axle and giving the wheel a few turns. In this way the
wheel may be removed and replaced without separating the nut from the wheel or
being obliged to lay the same down to become filled with sand and grit or soiling
the clothes and hands of the operator.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that
what I claim is :
1. In a wrench, the combination, with two curved members pivoted together
intermediate their ends, the inner extremities of said members being provided with
nut-receiving jaws and the outer extremities of said members with threaded
openings, of binding-screws mounted in the openings, substantially as specified.
2. In a wrench, the combination, with the oppositely-curved members pivoted
together intermediate their ends, the inner ends of said members terminating in
laterally-disposed nut-receiving jaws, each of which is recessed at its inner edge
to receive the upper edge of the opposite member, and the outer ends of which are
provided with threaded openings, of binding-screws mounted in the openings,
substantially as specified.
3. In a wrench, the combination, with opposite semicircular members pivoted
together intermediate their ends and terminating at their inner ends in laterally-
disposed jaws, one of said members terminating at its outer end in a threaded and
perforated head and the opposite member at its corresponding end in a transverse
head perforated at its opposite ends and at an angle to each other, of binding-
screws mounted in the perforations, substantially as specified.
4. In a wrench, the combination, with opposite semicircular sections pivoted
intermediate their ends and terminating at their inner ends in laterally-disposed
nut-receiving jaws, the outer edges of which are recessed to receive the outer
edges of said jaws, the outer end of one jaw terminating in a head having a single-
threaded perforation and the outer end of the opposite jaw terminating in a
laterally-disposed head having opposite angularly-disposed threaded openings, of
set-screws mounted in the openings and in the single perforation, loose washers
mounted on the set-scrows, and pads upon the inner faces of the washer, substan-
tially as described.
5. In a wrench, the combination of two curved members pivoted together

page_text: intermediate their ends, the inner extremities of said members being provided with
nut-receiving jaws and the outer extremities of said members being provided with
clamping devices to engage the hub-band, substantially as specified.
