Fig. 6 is a detail view.
Fig. 7 is a vertical transverse section taken on line z, z, of Fig. 3.
The frame consists of two plates A, B, held at the required distance apart by
posts or spacer blocks C, one end of which is tapped or secured to one plate and the
other end fitted to receive a screw c that passes through the other plate. In the
centre of this frame is secured, but so as to revolve freely, a ratchet wheel D,
through the centre of which passes a winding arbor shown as a square bar or
spindle E that slides freely so as to allow the end to be adjusted to any desired
width of spring. The lower end of this bar is fitted with a handle F, and the upper
end is provided with a round projection e, upon which is secured a collar G, pro-
vided with a catch or hook g. This collar I prefer to secure to the end e of the
spindle E by means of a screw f, that is of a length equal to the diameter of the
end e, and is screwed into the same, a hole being formed in the collar G so that
after it has been placed on the spindle the screw is turned so as to cause it to
project into the hole in the collar as shown in Fig. 6 thereby holding it in
position.
H, is a two armed pawl fulcrumed at its rear end between the two plates A, B,
so as to swing freely and so that the end of either arm can be thrown into contact
with the ratchet wheel D, by means of a spring i attached at one end to the
fulcrum h and at the other end to a pawl lever I preferably made of wire bent to
the form shown and fulcrumed between the plates A, B, the lower portion & extend-
ing a short distance below the bottom plate and formed with an arm i², by which
either arm of the pawl can be thrown in or out of gear with the ratchet wheel by
the thumb of the operator while holding the instrument in his hand. The object
of this ratchet wheel and two armed pawl is to allow the spindle E to be
turned in either direction so as to wind the spring either to the right or left as
required.
J, is a sliding block through which passes a clamp K a screw k preventing it
from falling out of the block but at the same time allowing a free vertical move-
ment. L is a screw that passes into the block J for clamping the jaws of the
clamp K to the spring when in the required position, the outer end of this screw is
Pavica 1

page_text: provided with a cross bar or thumb piece 7. In each of the plates A, B, is formed
a slot M through which the clamp K passes and can be adjusted in any position in
the said slots. N is a sight hole formed in the upper plate to allow the operator
to see the spring when adjusting the jaws of clamp K. P, P, are sleeves that pass
through both the plates A, B, and are provided at their lower ends with cams Q,
and their upper ends are screw-threaded and are formed with slots (preferably
four).
Rare screw threaded caps that fit on the upper ends of each of these
sleeves so that when the caps are turned down the upper ends of the sleeve are
forced inwards.
S, S are arms bent at right angles, one end of each passing down through one of
the caps R into the sleeve P and can be adjusted and clamped at any desired height
by turning down the cap R. Near the lower end of each of these arms is passed a
small pin r, that works in the slots in the upper end of the sleeve so that they
turn with the sleeves to adjust the arms S. S. at any desired height. The
outer or free end of these arms are bent inwards so as to form a pawl that
takes into one of the spaces between the teeth on the spring barrel shown in dotted
lines Figs. 1 and 3.
T is a screw secured in the lower plate B between the cams Q. Upon this screw
is fitted a clamping bar U, the upper end of which is provided with a loose collar V,
which when the bar U is screwed up tightly clamps, the cams Q thereby holding
the arms S firmly in place.
The cams Q are provided with a projection 9 (see Fig. 5) so that when the cams
are not clamped the arms S will be prevented from turning beyond a certain
distance as the projections q will come into contact with the screw T.
Each winder is provided with several (preferably three) collars G for various
sizes of springs. The collars that are not in use are held between the plates A, B,
as shown in Fig. 4. A spring cover W which swings on one post and snaps over
the other post preventing them from falling out at the end, and there is not room
for them to pass between the posts and the end of the pawl H.
The operation is as follows: Supposing it is required to remove a spring from the
barrel, the barrel is placed on the winder as shown in dotted lines, and the arms S
adjusted to the proper height for the teeth of the barrel. The handle F is then
turned until the catch g engages the spring, and the barrel turned until the hook in
the barrel which holds the outer end of the spring comes within about one half inch
of the jaws of clamp K. The arms S are then brought in contact with the teeth
on the barrel and are thereby clamped by turning the rod U as before described.
The instrument is then grasped with the left hand by the end opposite the arms S,
with the thumb over one end and the fore finger over the other of the ends of the
two arms S. Then the handle F is turned until the spring is nearly wound up.
This leaves the outer end of the spring so that clamp K can be adjusted to the end
of the spring and when done the jaws of clamp K are set firmly to the spring by
means of screw L. The barrel can now be removed by releasing the arms S.
Then by means of arm the lever I is pushed to the opposite side of pawl H, the
handle F is turned up a trifle which will allow the two armed pawl H to act on the
opposite arm and the spring will unwind. When it is desired to replace the spring
in the barrel, it is placed over the collar G and adjusted to hook g. The outer end
is placed in the jaws of clamp K and clamped firmly by screw L. Then the
handle F is turned and winds the spring. The barrel can then be placed over the
spring and the spring transferred from the winder to the barrel by releasing pawl H
letting the spring down by handle F and releasing clamp K.
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. A spring winder consisting of two plates of metal, connected together by posts,
a ratchet wheel mounted in the centre between the plates, an adjustable winding
arbor passing through the ratchet wheel, a two armed pawl and means for operating

page_text: the same, a clamping device for holding the outer end of the spring and arms for
holding the barrel substantially as set forth.
2. In combination with a spring winder means for holding the barrel consisting
of two bent arms S, sleeves P having cams Q at their lower ends, caps R, screw T,
collar V, and clamping bar U arranged and operated substantially as shown and
described.
3. In combination with a spring winder an adjustable clamp for holding the outer
end of the spring consisting of the sliding block J, clamp K and screw L, sub-
stantially as shown and described.
4. In a spring winder the combination of the frame A, B, C, ratchet wheel D,
and adjustable winding arbor E, handle F and collar G with the pawl H, pawl
lever I and spring i substantially as set forth.
5. In a spring winder the combination of the frame A, B, C, ratchet wheel D,
and adjustable winding arbor E, handle F, collar G, pawl H, pawl lever I and
spring with the adjustable block J, clamp K, and screw L, substantially as shown
and described.
6. In a spring winder the frame A, B, C, bent arms S sleeves P, cams Q, caps R,
screw T, collar V, and clamping bar U in combination with the ratchet wheel D,
an adjustable winding arbor E, handle F, collar G, pawl H, pawl lever I, spring i
and adjustable block J, clamp K, and screw L substantially as shown and described.
