PROVISIONAL SPECIFICATION.
Improvements in or relating to Turn Buttons.
I, ANDRE GOBRON of 31 Boulevard Henri IV. Paris in the Republic of France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to turn buttons and consists in the improvements therein
hereinafter described. The improved turn buttons are ospecially applicable to the
heads of the futchel bolts of carriages or to like bolts for receiving and rotaining
the ends of the traces.
Upon a suitable base, which in the case of a futchel bolt is the collar or head on
the end of the bolt, is an upright pin and on this pin is placed a helical spring. A
washer and cross pin retain the spring. The lower end of the spring projects and
takes into a recess in a cap or turn button which covers in the said pin and spring
and may be revolved thercon. The lower edge of this cap or button is cut away
to form a shoulder and on the head of the bolt is a corresponding shoulder, the
downward pressure of the spring causes the shoulders to be pressed or locked
together so that the button cannot turn or he turned until it is lifted against
the pressure of the spring sufficiently to bring the shoulders clear of one another.
In place of shouldering the button and head of the bolt or base as aforesaid. The
upright pin in the centre of the base may be squared at its upper end above the
spring and in the interior of the cavity in the button a square recess is made to
receive this squared end so that the button when pressed down by the spring
cannot turn or be turned upon the fixed central pin until it is lifted against the
pressure of the spring sufficiently to raise the square recess from off the squared
end of the pin.

COMPLETE SPECIFICATION.
Improvements in or relating to Turn Buttons.
I, ANDRE GOBRON, of 31 Boulevard Henri IV, Paris, in the Republic of France,
Manufacturer, 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:-
This invention relates to turn buttons and consists in the improvements therein
hereinafter described. The improved turn buttons are especially applicable to the
heads of the futchel bolts of carriages or to like bolts for receiving and retaining
the ends of the traces.
Upon a suitable base, which in the case of a futchel bolt is the collar or head on
the end of the bolt, is an upright pin and on this pin is placed a helical spring. A
washer and cross pin retain the spring. The lower end of the spring projects and
takes into a recess in a cap or turn button which covers in the said pin and spring
and may be revolved thereon. The lower edge of this cap or button is cut away
to form a shoulder and on the head of the bolt is a corresponding shoulder, the
downward pressure of the spring causes the shoulders to be pressed or locked
together so that the button cannot turn or be turned until it is lifted against the
pressure of the spring sufficiently to bring the shoulders clear of one another. In
place of shouldering the button and head of the bolt or base as aforesaid, the
upright pin in the centre of the base may be squared at its upper end above the
Prior 81

page_text: spring and in the interior of the cavity in the button a square recess is made to
receive this squared end so that the button when pressed down by the spring
cannot turn or be turned upon the fixed central pin intil it is lifted against the
pressure of the spring sufficiently to raise the square recess from off the squared
end of the pin.
In the accompanying drawing the construction of this improved turn button is
illustrated,
Fig. 1 being a side elevation of the base with the bolt to which it forms a hend
and a sectional view of the turn button..
Fig. 2 is an elevation of the same parts.
Fig. 3 a section on line xy of Fig. 1.
Fig. 4 a similar view to Fig. 1 illustrating the modified construction previously
described.
Fig. 5 is a section on line 'y' of Fig. 4.
In this instance the base C is shown upon a bolt A. The base C is preferably
made cylindro-conical and the pin C projects from its upper surface. C is the
helical spring which surrounds the pin C and is held thereon by a washer D and
cross-pin D (Fig. 1) or by washer D and nut J (Fig. 4) according to the
construction adopted. The turn-button preferably of the shape shown is
hollowed at H H' to house the pin C with the spring C" and washer D or as in
Fig. 4 at H H'J' to house the aforesaid parts und provide a squared recess J' to
lock upon the square J. I is the recess in the button E to receive the end of the
spring CB, F indicate the locking shoulders which are employed in the base
and button in the construction first described and illustrated in Fig. 1.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A base C, a pin C thereon and a helical spring in combination with a
turn button E having a recess for the housing of said pin and spring and engaged
with said spring and locking shoulders B F in the base and in the button for action
as described.
2. A base C, a pin C thereon and a helical spring C" in combination with a
turn button E having a recess for the housing of said pin and spring and engaged
with said spring, a prismatic part J fixed in relation to the base (and a
corresponding prismatic recess J¹ in the turn button for action as described.
