Improvements in and connected with Hay Rakes and the like.
I HENRY WILLIAM MATHERS, of Inchmichael, Errol, in the County of
Perth, N.B., do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to facilitate the fitting of the teeth of hay rakes
and the like.
According to my invention, I form the teeth of two strips of steel, segmental in
section, the ends being welded together to form points at each end.
Suitable projections are formed upon the teeth, at about the middle, so that when
a wedge, fitting the cavity in the tooth, is driven towards the middle of the tooth,
the projections are forced apart and into recesses formed in the frame or cross-bar
of the rake, thus effectually securing the tooth in position.
By the use of my invention, the teeth may be readily interchanged or renewed,
it only being necessary to withdraw the wedge and on pinching the two strips forming
the tooth, together, the tooth can be easily withdrawn, thus saving much time and
expense.

Improvements in and connected with Hay Rakes and the like.
1, HENRY WILLIAM MATHERS, of Inchmichael, Errol, in the County of
Perth, N.B., do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
My invention relates to the manufacture and fitting of improved teeth to hay
rakes and analogous implements, and its object is to afford improved facilities for
fitting and renewing such teeth.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
figures of reference indicate corresponding parts.
Fig. 1 is a longitudinal side view of one of my improved teeth, the frame or
cross-bar being shown in section.
Fig. 2 is a similar plan view, at right angles to Fig. 1.
Fig. 3 is a cross-section of one of the teeth, without the wedge or key.
4 is the frame or cross-bar into which the teeth are driven.
Each tooth consists of two segmental strips of steel 5, 5, the two ends of each
being welded together to form points at 8, at each end of the tooth, and leaving
the intermediate portions separated, as shown in Figs. 2 and 3. About midway on
each side of the tooth a projection 6 is raised in the metal. 7 is a wedge or key,
which is used to expand the central portion of the tooth, after its insertion in the
frame.

page_text: When the wedge is placed near one end of the tooth, the two sides of the tooth
are sufficiently resilient to enable it to be easily pressed into or removed from the
hole made for its reception. When the tooth is inserted in the bar for fixing, the
wedge 7 is driven endwise, whereby the segmental sides of the tooth are expanded,
and the projections 6 on each side are forcibly driven into the grain of the wooden
bar, whereby the tooth is securely locked in position.
When the improved teeth are intended to be fitted into metallic bars or frames,
the projections 6 may be dispensed with.
By the use of my invention, the teeth of rakes and analogous implements may be
readily fitted, removed, renewed and interchanged, it being only necessary to drive
the wedge end wise from the middle, and on pinching the two stripes forming the
tooth together, the tooth, can be easily withdrawn, thus saving much time and
expense.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
:―
1. The improvements in and connected with hay rakes and the like, substantially
as and for the purposes described.
2. The improved construction of teeth, consisting of two resilient segmental side
pieces united at their ends and fitted with an internal wedge or key for expanding
the side pieces, with or without projections 6, substantially as and for the purposes
described and illustrated by the drawings.
