Improvements in Roller Bolts for Splinter Bars.
I, STANLEY GEORGE DODSON, of 88, Westbourne Street, Sloane Square, in the
County of Middlesex, Jobmaster's Assistant, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to enable the traces to be readily disconnected
from the splinter bar in case of the horses falling, or kicking over them.
The roller bolt is made hollow and fits a pin fixed to the under side of the
splinter bar and projecting upwards through a hole in it there being a space
between the sides of the hole and the pin to receive the tubular roller bolt.
A spring is interposed inside the bolt between its top and the top of the pin
or the bottom of the hole. The bolt carries a lug or lugs fitting corresponding
grooves in the hole in such manner that when the bolt is pressed home com-
pressing the spring a partial turn secures it to the splinter bar by a bayonet
joint. Preferably there is a sleeve or roller on the outside of the bolt so that
it can be readily turned to unlock it.

I, STANLEY GEORGE DODSON, of 88, Westbourne Street, Sloane Square, in the
County of Middlesex, Jobmaster's Assistant, 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:-
The object of this invention is to enable the traces to be readily disconnected
from the splinter bar in case of the horses falling or kicking over them.
The roller bolt is made hollow and fits a pin fixed to the under side of the
splinter bar and projecting upwards through a hole in it there being a space
between the side of the hole and the pin to receive the tubular roller bolt.
A spring is interposed inside the bolt between its top and the top of the pin
or the bottom of the hole. The bolt carries a lug or lugs fitting corresponding
grooves in the hole in such manner that when the bolt is pressed home com-
pressing the spring a partial turn secures it to the splinter bar by a bayonet
joint. Preferably there is a sleeve or roller on the outside of the bolt so that
it can be readily turned to unlock it.
Figure 1 is a vertical section of a roller bolt constructed according to this
invention in place on the splinter bar, and Figures 2, 3 and 4 show the parts
separately.

page_text: a is the tubular roller bolt having a roller or sleeve b free to turn on its
outside and a spring c fixed inside it. At its bottom are pins or lugs d. e is
the splinter bar having a hole sunk in it in which is a solid pin f fixed by a
nut g. h is a flanged tube fitting the hole in the splinter bar and secured by
screws j. are grooves formed in the tube h to receive the pins d. Preferably
the lower ends of these grooves turn slightly upwards as shown in dotted lines
in Figure 1 to restrain the tendency of the bolt a to rotate.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
-
1. The combination of a tubular bolt fitting a hole in the splinter bar, a spring
inside it, and a pin fixed in the hole.
2. Roller bolts for splinter bars substantially as described and illustrated in
the drawings.
