PROVISIONAL SPECIFICATION.
A New or Improved Tool for Forming Grooves or Depressions in
Making the Junctions of Cycle and Motor Car Frames and for
other similar purposes.
We, FREDERICK BILLING, of Livery Street, Birmingham, Manufacturer, and
WILLIAM EDWARD PARTRIDGE, of 722, Coventry Road, Small Heath, Birmingham,
Traveller, and WILLIAM SAMUEL MIDDLETON, of 21 to 23, Coleshill Street, Birming-
ham, Manufacturer, all in the County of Warwick, do hereby declare the nature
of our said invention to be as follows:-
Our invention has for its object a new or improved tool for forming grooves
or depressions in making the junction of cycle and motor car frames and other
similar purpose and which is specially designed to form the junctions which are
the subject of the Patent granted to Frederick Billing and William Edward
Partridge No. 24013 A.D. 1896.
We take two semicircular or curved pieces of steel or other suitable metal and
hinge them to each other in such a manner as to form a nearly complete circle.
One of the curved pieces may finish with a handle for operating the tool or a handle
may be hinged to it which will turn out of the way for convenience in handling
the tool so as to work it in confined positions. In the edge or back of these curved
pieces we drill a number of holes in one two or more rows of such a diameter
as to be suitable to drop in a ball of suitable diameter to form the
necessary groove or grooves required in forming the junctions. The point of
the drill only penetrates sufficiently to allow the balls to project sufficiently
to form the grooves without falling out. These balls are secured and tightened up
by a separate screw set pin behind each ball. This makes a compact and cheap
tool for use in small shops.

page_text: Traveller, and WILLIAM SAMUEL MIDDLETON, of 21 to 23, Coleshill Street, Birming-
ham, Manufacturer, all in the County of Warwick, do. hereby declare the nature
of our said 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 has for its object a new or improved tool for forming grooves or
depressions in making the junctions of cycle and motor car frames and for other
similar purposes and which is specially designed to form the junctions which are
the subject of the application for a Patent granted to Frederick Billing and William
Edward Partridge No. 24013 A.D. 1896.
We take two semicircular or curved pieces of steel or other suitable metal and
hinge them to each other in such a manner as to form a nearly complete circle.
One or both of the curved pieces may finish with a handle for operating the tool
or a handle may be hinged to it which turn out of the way for convenience in
handling the tool so as to work it in confined positions. In the edge or back of
these curved pieces we drill a number of holes in one two or more rows of such a
diameter as to be suitable to drop in a ball of suitable diameter to form the neces-
sary groove or grooves required in forming the junctions. The point of the drill
only penetrates sufficiently to allow the balls to project sufficiently to form the
grooves without falling out. These balls are secured and tightened up by a separate
screw set pin behind each ball. This makes a compact and cheap tool for use
in small shops.
In order that our invention may be more clearly understood and easily carried
into practical effect we have appended hereunto two sheets of drawings upon which
we have illustrated examples of our improved tool.
Figure 1 is a part sectional view of our tool ready for use.
Figure 2 is an edge view of Figure 1.
Figure 3 is an inside edge view of one of the jaws shewing the balls arranged
so as to work around a spiral groove.
Figure 4 shews a modified form of our tool having two rows of balls and only
one shaft or handle.
Figure 5 is an edge view of Figure 4.
Figure 6 shews another modified form of tool with a simple row of balls.
Figure 7 is an edge view of Figure 6.
In carrying our invention into practice we take the two semi-circular or curved
piece or pieces A and A¹ of steel or other suitable metal having the shafts or
handles Band B¹. We then hinge these two semi circular pieces or jaws to each other
at a² so as to form a complete or nearly complete circle. In the edge or back of each of
the semi-circular pieces or jaws we drill and tap say three holes of such a diameter
as to be suitable to drop in the balls D which balls are of suitable diameter to form
the necessary groove or grooves required in making the junctions. The point of
the drill when forming these holes only protrudes sufficiently to allow a portion
of each ball to project when inserted as clearly shewn at Figures 1, 4, and 6.
Each ball is held in position and adjusted by the separate screw set pin F which
is screwed into the hole after the ball has been inserted the end of which form, a
bearing surface for the ball and these ends may be pointed or cupped or hollowed
if necessary. In some cases we may when desired use another ball or balls D₁
which fit into recesses formed in the inner edges of the jaws as shewn at Figure 1.
For the purpose of holding the jaws or circular pieces A and A¹ more firmly
around the junction when forming the grooves we secure the locking device H to
the end of one of the shafts which consists of the U shaped clip H pivotted at h¹
to the shaft B. In the base or end of this clip we drill or tap a hole in which
we insert the screw pin J. It will be readily understood that when this clip is
turned so as to enclose the ends of both shafts or handles as shewn at Figure 1.
and 2 the screw pin tightened up that the end of this pin will bear against the
end of the shaft BI thus forcing the two shafts together.
In the tool as shewn at Figure 3 we drill and tap the holes in which the balls

page_text: are inserted so as to form a portion of a spiral which enables the tool to be used
with a junction in which spiral grooves are formed.
In the tool as shewn at Figures 4 and 5 we have provided a double row of balls
so as to form two grooves simultaneously and we have also dispensed with one of
the shafts or handles and in the loose end of the part A¹ we form a hole for insert-
ing the screwed pin K which screws into a tapped hole in the part A by which
We may
means the jaws are firmly held in position when forming the junction.
if necessary use more than two rows of balls either with a tool having one or two
shafts or handles.
In the modification as shewn at Figures 6 and 7 we also dispense with one of
the handles or shafts and tighten the jaws together by the screw pin K. In this
case we form the handle or shaft 132 at an angle to the jaws so as to enable the
tool to be more conveniently used when making certain junctions. Or the handle
or handles or shaft or shafts may in all cases be hinged or pivotted to the jaws A
and A¹ so as to enable them to turn out of the way for convenience in handling,
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:-
CLAIMS.
First The new or improved tool for forming grooves or depressions in making
the junctions of cycle and motor frames and other similar purposes consisting
essentially in the semi-circular or curved piece or jaws such as A and A' either with
one or two shafts or handles and having a number of holes formed in each for
inserting one or more rows of balls the said balls being held in position adjustably
by the screw set pins such as F in the manner and for the purpose substantially
as herein before described and as shewn upon the drawings.
Second-In the tool as claimed by the preceding claim adjusting the balls by
the screw pins F in the manner and for the purpose as herein set forth and as
shewn upon the drawings.
:
Third In a tool as claimed in the First Claim arranging the balls in the jaws
or circular parts spirally in the manner and for the purpose substantially as herein
set forth and as shewn upon the drawings.
