PROVISIONAL SPECIFICATION.
Improvements in Claw Brackets for the Fittings and Accessories of
Velocipedes and like purposes.
We, JOSEPH LUCAS, and HARRY LUCAS, both of the Tom Bowling Lamp
Works, Little King Street, Birmingham, in the County of Warwickshire, Lamp
Manufacturers, do hereby declare the nature of this invention to be as follows:-
Our invention relates to an improved claw bracket or clamp for attaching the
fittings of velocipedes to the frames or parts thereof, though it may also be used
for a similar purpose on other machines or articles, and it consists in making the
one part of the claw or jaw adjustable with respect to the other, the object being to
give increased adjustability and greater security from working loose from vibration
and other causes.
We attain this end by making a clamp or jaw of a greater width than usual. The
one side of the jaw is fashioned to form the fixed part of the jaw or claw, and the
other side is adapted to receive a set screw for adjusting the movable part of the jaw
or claw which consists of a suitable shaped piece having projecting flanges carrying
inwardly projecting studs or their equivalents, adapted to engage with undercut
flanges or their equivalents on the bottom of the fixed part of the jaw or claw
bracket and thus confine the movable piece on the said fixed part and yet allow of
its free movement for adjustment.
It will be seen that with this construction of claw bracket a very wide range of
adjustment can be obtained and that as the movable piece is free enough to bed, or
adjust itself, on the part to which the bracket is adapted to be clamped, it obtains a
firm grip on the said part and is not liable to work loose through vibration and
other causes.

COMPLETE SPECIFICATION.
Improvements in Claw Brackets for the Fittings and Accessories of
Velocipedes and like purposes.
We, JOSEPH LUCAS and HARRY LUCAS both of the Tom Bowling Lamp
Works, Little King Street, Birmingham, in the County of Warwickshire, Lamp
Manufacturers, 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 :-
Our invention relates to an improved claw bracket or clamp for attaching the
fittings of velocipedes to the frames or parts thereof, though it may also be used for
a similar purpose on other machines or articles, and it consists in an improved
method of mounting the adjustable claw or jaw, the object being to give increased
adjustability and greater security from working loose from vibration and other
causes.
We attain this end by making a claw bracket of a greater length than usual.
The one end of this bracket is fashioned to form the fixed jaw or claw, and the

page_text: other is adapted to receive a setscrew for operating the adjustable jaw or claw,
which consists of a suitably shaped piece having flanges carrying inwardly projecting
studs, or their equivalents, adapted to engage with flanges, or their equivalents, on
the claw bracket. I thus confine the adjustable jaw piece on the bracket carrying
the fixed jaw and yet allow of its free movement for adjustment.
In order that our invention may be fully understood we will more particularly
describe it making reference to the accompanying drawing in which
Figure 1 is a view in side elevation of our improved claw bracket.
Figure 2 is a view in transverse section showing the method of attaching the
adjustable jaw.
Figure 3 is a view in side elevation of the bracket carrying the jaw, and
Figure 4 is a view in end elevation thereof.
Figures 5 and 6 are views in side elevation and transverse section respectively
showing another form my invention may assume.
Throughout the several views similar parts are marked with like letters of
reference.
Referring to Figures 1. 2. 3. and 4 of the accompanying drawing, A designates
the claw bracket having a fixed jaw or claw, A¹ formed on one end of it and a
lug A2 on the other end thereof. Through the lug A² is threaded a set screw B
having a round or pointed end. C designates the adjustable jaw or claw having
two flanges c. c carrying inwardly projecting studs or pins c c adapted to
engage with flanges a. a on the bracket A, thereby confining the said adjustable
jaw or claw to the bracket but allowing it free movement thereon, thus enabling
it to accommodate itself to the part to which the bracket is to be fixed. The
adjustable bracket C is preferably provided with a countersunk hole C² for the
end of the set screw B to engage with. The adjustable jaw or claw C is
placed in position on the bracket A either by spreading the flanges c. c to
enable the studs or pins c¹ c¹ to pass over the flanges a. a of the bracket A and
afterwards closing them, or by so shaping the end of the bracket A. carrying
the lug A² that it can be slipped on to the said bracket when the set screw B
is removed.
.
Instead of forming studs or pins c c on the flanges c. c of the adjustable jaw
or claw C, we sometimes form inwardly projecting flanges c¹ c¹ as shown by
Figures 5 and 6 of the accompanying drawing.
It will be seen that with this construction of claw bracket a very wide range of
adjustment is obtained, and that as the adjustable jaw or claw is free to bed or
adjust itself on the part to which the bracket is fixed, it obtains a firm grip thereon
and is not liable to work loose through vibration and other causes.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described and illustrated by the accom-
panying drawing, but that we hold ourselves at liberty to make such changes and
alterations as fairly fall within the spirit and scope of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1st. The improved claw bracket, constructed arranged and operating substantially
as and for the purpose set forth.
2nd. In a claw bracket, the combination of the bracket carrying the fixed claw or
jaw at one end and a lug at the other end, of the adjustable claw or jaw mounted
loosely on the bracket and kept engaged therewith by means of inwardly projecting
studs or flanges carried by the said claw or jaw and engaging with flanges on the
said bracket, and of the set screw threaded into the lug on the bracket and adapted
to operate the adjustable jaw or claw, as and for the purpose set forth.
3rd. The improved claw bracket, constructed as herein before described and
illustrated by Figures 1 and 2 of the accompanying drawing.

page_text: 4th. The improved claw bracket, constructed as hereinbefore described and
illustrated by Figures 5 and 6 of the accompanying drawing.
Dated this 15th day of June 1891.
