Improvements in Anchors.
I, FREDERICK BALDT, residing at the corner of Front and Penn Streets, Chester,
in the County of Delaware and State of Pennsylvania, United States of America,
Gentleman 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 :-
My invention relates to certain improvements in anchors. The object of my
invention is to produce a ball bearing anchor that can be cast; a ball bearing anchor
in which the crown piece and flukes cannot revolve on the shank, whereby the flukes
will catch with certainty.
It consists of a rectangular shank with a round ball or globe on the end, a crown
piece having a socket in which the ball or globe is seated, thus making a true ball and
socket joint, with an opening on two sides to allow the mud and small stone to wash
through. The shank is held in the socket by means of a pin passing through the
lugs on the crown piece back of the ball or globe on the shank. Thus it will be
seen that the anchor is so constructed that it can be cast in steel and not forged.
In the drawings:
Fig. 1 is a front elevation of my improved anchor.
Fig. 2 is a vertical section on the line X-X.
Fig. 3 is a similar view with the shank thrown to one side.
Fig. 4 is a bottom plan view.
A represents the shank, rectangular in cross section which is provided with a
round ball or globe a, on the end. The ball or globe a, is cut away at a' thus
forming a groove with a curved bottom to be hereinafter referred to. B is the crown
piece having a central rectangular longitudinal opening b, on the fluke side and
a round opening 6' on the rear side. 62 are lugs extending from the crown piece
in which are formed openings. 63 are fluke-arms. is the pin with which the
shank is secured in the crown piece.
.
The bottom of the ball is cut away as at a¹ forming
groove which inclines
from the center towards the sides of the ball. Thus when the shank is thrown to
one side, this groove registers with the opening 6, in the crown piece, thereby forming
an opening through which sand, mud, etc. may wash through. Extending from this
groove is a rib a³, which is also provided with a groove a, the bottom of which is
curved as shown in the drawings. The pin 6 works in this groove thereby keeping
the ball at all times snugly in the opening b¹.
The rectangular shank is passed through the rectangular opening b in the crown
piece, and the ball a, is seated in the round opening 6¹ in the crown piece. The
pin & is then passed through the lugs 62 and the groove in the rib a³ on the bottom
of the ball a. It will be noticed that the bottom of this groove is curved. The
pin b* fits snugly against the ball thus holding it, as above stated, at all times close
in the opening b¹ thereby forming a true ball bearing or socket and giving the shank
a full bearing on all sides.
The construction of the few parts of this anchor requires no machine work, and
the assembling of the parts is very simple thereby considerably reducing the cost of
manufacture and the selling price.
The shank being rectangular and the opening b through which it passes being also
rectangular it is impossible for the crown and flukes to revolve, thus enabling the
anchor to catch with certainty.

page_text: 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
In an anchor, a rectangular shank, a ball integral with and on one end of said shank,
a groove having a curved bottom, formed on the bottom of the said ball, a crown piece
having integral flukes, a central longitudinal opening in the fluke side of the crown
piece, and a cup-shaped opening on the rear side, lugs extending from the crown
piece and provided with openings, a pin adapted to pass through said openings and
work in the groove in the bottom of the ball.
