PROVISIONAL SPECIFICATION.
Improved Drill or Ratchet-brace Stand or Support.
I JOSEF JUERGENS, of Hontrop, Germany, Carriage Inspector, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a holder or carrier for drill or ratchet braces which can
be set and secured for the drill to work at any angle, and is particularly applicable
for drilling railway rails. The brace carrier consists of two arms having the upper
ends screw threaded for a cross piece to screw down, this cross piece carries the
bearing for the point end of brace. The lower end of the arms is connected, by
socket, cross-pins, or other suitable means, to claws to engage the rail or other
article to be drilled, and these claws are fitted with an adjustable clamping or other
device to hold and secure the carrier at any angle. By making the arms separate
from the claw part and to be fitted to same, enables different shapes of claws to be
used to suit different kinds of articles to be drilled.

COMPLETE SPECIFICATION.
Improved Drill or Ratchet-brace Stand or Support.
1, JOSEF JUERGENS, of Höntrop, Germany, Carriage Inspector, do hereby declare
the nature of this invention and in what manner the same is to be perforined, to
be particularly described and ascertained, in and by the following statement :-
This invention relates to a holder or carrier for ratchet or crank braces, capable
of applying the drill to drill a hole at any angle, and is particularly suitable for
drilling railway rails.
To enable the invention to be properly understood, I will proceed to describe
the same with aid of the accompanying drawings, which illustrate an arrangement
for drilling railway rails.
Figure 1, is a front elevation of a brace carrier complete.
Figure 2 a plan of a part shown in the preceding figure.
Figures 3 and 4 modifications.
a, b, are the arms having the upper ends screw threaded to carry a cross piece c,
preferably having a fork at each end in which is a nut d, with female thread to
engage the thread on arms a, b; the nut d is secured by screws e: in the middle
of cross piece c is a bearing m for point of brace. The lower ends of arms a, b,
are made with a socket to fit on to tongues of claw parts to which they are
secured by cross key n. By making the arm parts a, b, separate from the claw
part h, enables different shapes of claws to be connected to suit different kinds of
work. Assuming a rail to be passed through the carrier, the sides of top and
bottom would bear upon the angle part A', and would be prevented from slipping
off by the adjustable collars i, which are first set to secure the rail and then
secured by set screws o.
The drawing shews the position of the carrier when used for drilling a straight
hole. If the hole is desired to be drilled at an angle one of the sides of the carrier
is screwed down so that one claw h will come lower than the other, by this way the
rail laying on the claws h¹, h', will be placed at an angle and so correspondingly
drilled.
In place of the cross piece c, being adjustable and held by screw threads, it can

page_text: be adjusted and secured as shown at Figures 3 and 4. In these views the arm a¹,
slides within a tubular part and is secured at any height by cross pins m, passing
through holes m, m, m, and the cross piece c, is also secured in like manner.
Having now particularly described and ascertained the nature of this inveu-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A holder or carrier for ratchet or drill brace, having the claw ends made
separate from the other parts to enable different shaped claws to be used to suit
different kinds of work, substantially as described and illustrated by the accom-
panying drawings.
2. A holder or carrier for ratchet or drill brace, arranged that one side may be
set lower than the other to enable the article held therein to lay at an angle while
being drilled so that the hole may be drilled at an angle, as hereinbefore described
and illustrated by the accompanying drawings.
