Figure 2 is a detail view of a modified arrangement of clutch and latch.
Figure 3 is a view of another modification, and
Figures 4 and 5 show details.
Figure 6 is a detail of the connection between the standard and keel.
Figure 7 shows details of the latch and weight.
Figure 8 is a face view of the upper forked end of the standard shown in
Figure 2.
I have shown only one end of the boat, the mechanism at the other end being
on the same principle but the form may vary to suit boat. The latch 1 for
engaging the fall hook or link is pivoted to the top of the standard 2 extending up
through the thwart and connected at its lower end with the boat bottom keel or
continuation thereto at 3. The latch extending inwardly and downwardly to
engage the wall of the clutch 4 which has an open side 5 Figs. 1 and 4 which when
brought to a position opposite the latch releases the same. The clutch is carried
by a shaft section 5¹ fitted to slide vertically in a hollow section 6 connected to
the rest of the shaft by the universal joint 7. The sections 5 and 6 are connected
to rotate together by a pin 8 in the section 5 entering a slot in the section 6. A
spring 9 in the section 6 keeps the section 5' with its clutch normally up in position
to engage the latch. Bearings 10 extending from the standard 2 supports the
shaft in vertical position. The shaft section 5 has a handle 11 pivoted thereto, to
hang normally down out of the way and which may act as a lock and which by
raising up to a horizontal or approximate horizontal position will enable a man to
turn the shaft for releasing the latch from the clutches, very little effort being
required for this, the flexible shaft causing the latches at the two ends of the boat
to be released simultaneously. A gear wheel may be arranged on the shaft
Price 1

page_text: centrally of the boat and a lever and segment used to operate it. If the latches
and clutches should be in locked position and it is desired to attach the fall or
tackle, this may be readily done if a common or improved self closing hook is used
on the tackle by, simply hooking it under the latch, but, with a link, in order to
avoid the turning of the whole shaft so as to release the latch from the clutch and
then resetting the parts. after the link.is engaged, the man merely forces down the
clutch by pressing the link or block upon its upper edge, the shaft section 51
yielding for this purpose, until the link gets below, the end of the latch when it is
slipped laterally past the point thereof and thus engaged, the clutch rising to engage
the latch as soon as the pressure is released. I have provided a spur on its upper
edge, to form a rest for the link or block.
'
The latch has a check ledge 13 by which its releasing movement is limited and
it is prevented from flying over out of position, which, also serves as a means to
return latch to its normal place by preponderance. A stop. shoulder 13¹ is also
provided which will maintain the latch exactly normal to the clutch.
A tripping lever for operating the shaft is shown in detail. in Figure 5 in side
and plan view.
It has two clamping jaws 14 which when the lever is lifted, embrace 'the shaft
section which is flattened at 5* and thus relieve the pivot of the handle of all strain
in turning the shaft which is of importance in desperate cases when the boat
must be got overboard with a crowd of people in it. With this tripping gear the
boats can be got clear when there is no time, to man the falls. Instead of this
construction the handle may be pivoted in ears formed integral on the shaft section
as indicated in Figure 1. In Figure the standard is shown as in one piece and
as having a lateral extension or support 15, connected to the thwart. In Figure 4
the upper. end of the standard fits into a socket 16 on the under side of the
forging 17 bolted to the thwart and from this the standard 2' for pivotally
supporting the latch extends upward. This forging also has a socket 18 in which
the clutch head fits and turns, the shaft section extending down through the bottom
of the forging and said clutch head extending up above the socket to engage the
link. In Figure 1, the clutch was held by bearing 10 integral with standard and
adapted to permit the clutch head to yield vertically as described. In Figure 2 the
clutch head does not yield vertically but instead the latch is made to yield from its
engagement with the clutch for connecting the link without disturbing the shaft.
For this purpose. the upper bearing standard 21 is in the form of a fork Fig. 8
in which the latch is pivoted, the opening of the fork permitting the latch to
swing backwardly within it to become free from the clutch and allow the link to
pass beneath it. The latch is pivoted on the pin 20 by its bifurcated ears 21
Figure 7 and between these ears is pivoted on the said pin the weight 22 having
a projection 23.bearing against the arm 24 of the latch, the arrangement being such
that the weight will return and hold the latch in engagement with the clutch and
will allow the latch to yield freely when placing the link. The weight is formed
separate from the latch so that the latch. may swing freely upward in releasing
the fall without carrying the, weight with it. In Figure, 3 the latch is arranged
to yield the spring 25 taking the place of the weight described. The action of
the part is shown in dotted lines." In all the forms described the yielding effect
is secured, either by the yielding of the clutch or by the, yielding of the latch or
both. In Figure 4 a stop 26 is shown for limiting the rotary movement of the
clutch so that it will stop exactly in open or closed position. The bearings for
the clutch shaft may either be integral with the standard or clamped thereto.
Figure 6 shows the preferred manner of attaching the standard to the keel and
kelson especially for heavy boats. The lower end of the standard is slightly
reduced and passes through a plate 30 in the keel, the lower threaded end of the
standard being held by a nut below the plate. For additional strength a plate 31
is fixed on the screw threaded part of the standard and the kelson 32. Through
this plate the bolts 33 extend down through the kelson and keel and through the
plate 30 being held by nuts on the lower screw threaded ends of the bolts. This

page_text: construction affords not only means of additional strength but also a means of
adjusting the standard.
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. In a boat detaching device. the clutch the rotary shaft for operating the
same and the latch, either the latch or the clutch or both being yielding, sub-
stantially as described.
2. In a boat detaching device, the yielding clutch and the shaft for operating the
same, substantially as described.
3. In a boat detaching device, the clutch and the yielding latch adapted to
permit the engagement of a link and the spring or weight arranged as set forth
for returning and holding the latch in engagement with the clutch, substantially as
described.
4. The general arrangement and combination of parts herein set forth.
5. In a boat detaching device the standard, the latch pivoted thereto, the clutch,
the shaft therefor, said standard being connected with the bottom of the boat,
substantially as described.
6. The adjustable standard connected with the boat and carrying the detaching
device.
7. In combination the standard having the fall detaching mechanism at its upper
end, the plate 30, the plate 31 connected to the standard and engaging the keel and
kelson and the bolts 33, substantially as described.
8. In combination, the latch, the yielding clutch, the shaft sections 5 and 6 and
the spring, substantially as described.
