Improvements in or relating to Eyes or Sockets for Fixing Teeth in
Agricultural Horse Rakes or Hay Collectors.
JOHN MCLAREN, Ironmoulder, Mayfield Cottage, Stenhousemuir, Stirlingshire,
do hereby declare the nature of this invention to be as follows:-
My improvement is in the eye or socket for fixing teeth of horse rake or hay
collector.
I have them made in two or more parts and when placed together and held by
means of screws or bolts, forms the eye or socket, representing now a whole or
those now in use. When the tooth is to be fixed into the eye or socket, the
tooth is put into one half and other on top, secured with bolts or screws as herein-
before described.
The tooth is held or secured in position in said eye or socket by means of a notch
being punched out at end of tooth, while in the one half of eye or socket there is
cast a projection to fit into notch in tooth end, so that when both halves of eve
or socket are together and secured by bolts or screws, the tooth is securely held
in position.

Improvements in or relating to Eyes or Sockets for Fixing Teeth in
Agricultural Horse Rakes or Hay Collectors.
I, JOHN MCLAREN, of Mayfield Cottage, Stenhousemuir, in the County of
Stirling, N.B., Ironmoulder, 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 eyes or sockets applicable for holding and fixing the
teeth of horse rakes or hay collectors. Hitherto each socket has been cast in
one piece, and difficulty has been experienced in fitting the teeth in the socket,
furthermore many sockets are of no use when cast owing to defects in the bore.
By my invention however these defects are avoided and a saving is effected in
the cost of manufacture, while the sockets can be removed if broken and replaced
by new ones without the dislocation of any part of the machine as is necessary
at present.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which,
Figure 1 is a perspective view showing the manner of socketting a horse-rake
tooth or arm in its socket, but with the parts separated;
Figure 2, the application of the invention to a bedstead;
Figure 3. a section on line a b (Figure 1).

page_text: In these, A is the socket, which, according to my invention, is made in two
halves, so that when the two halves are placed together and held by means of
screws passed through the plain holes B and into the screwed holes B₁ form an
entire socket. These screwed holes B₁ are formed in nuts actually moulded into
the casting (Figure 3) and as the nuts can be made of stronger metal than the
socket is made of, this is a feature which should recommend itself to manufacturers.
C is the tooth or arm of a horse rake or hay collector which has to be fixed in the eye
or socket. This arm is held or secured in position in the socket by means of a
cross notch D which is punched out or otherwise formed near the end of the
tooth, while in one half of the socket there is cast a projection E adapted to fit
into the notch, in such manner that when both halves of the eye or socket are
placed together and secured by bolts, the tooth or arm C is firmly held in position
in the socket, and cannot come out by reason of the projection engaging in the
notch. G are abutments in both halves of the socket which keep the tooth C
rigid and prevent lateral movement. Furthermore, one of the two halves of the
socket may be provided with lips at or about H which lap over the corresponding
parts of the other half of the socket and keep the two halves true and square when
placed together. To remove the tooth or arm C all that is necessary is to dis-
connect the two halves of the socket by unscrewing the bolts, it can then be
removed from engagement with the projection E, and replaced by a new arm.
Fis the driving shaft on which the sockets are mounted.
In thus describing my invention it is obvious that it is not confined exclusively
for the purpose of fixing teeth or arms in agricultural horse rakes or hay collectors,
as it may be applied also to fixing ornaments on balustrades or panels, also for
fixing bars in gates, for fixing tubes, bars and the like, on bedsteads, also in the
construction of road scrapers, cycles and other structures where such sockets or eyes
are applicable. Figure 2 shows by way of example the application of the invention
to bedsteads in which the bars C₁ take the place of the tooth or arm C, and the
bars take the place of the driving shaft F. In such case however I prefer to
use screws instead of bolts with their heads flush with the surface of the socket.
so that the screws may be invisible.
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 improvement in fixing the teeth or arms of horse rakes or hay collectors
in their sockets, which consists in forming the socket in halves and the arm or tooth
where it is socketted into the socket with a notch, adapted to be engaged by a
projection in the socket whereby if the two halves of the socket be placed together
and secured by bolts or screws, the tooth or arm is securely locked in position in
the socket by the projection engaging in the notch.
2. For the purpose of fixing teeth in sockets for use in connection with horse
rakes, and hay collectors forming the said teeth where they are socketted into
the socket with a cross notch, and making the socket itself in two halves with a
projection inside adapted to engage the cross notch in the end of the tooth, whereby
if the two halves of the socket are bolted together with the tooth placed therein,
these latter are locked securely and firmly in position substantially as described.
3. The eye or socket for holding the teeth of horse rakes & hay collectors, con-
structed and arranged substantially as described and shown.
