Improvements in Cleats or Devices for Fastening or Holding Cords,
Picture Wires, or the like.
I, MATTHIAS BOYCE of 28 Brook Street, Bond Street in the County of Middlesex
Solicitor 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 :-
The object of my invention is to provide a cleat or device for fastening or holding
cords picture wires or the like which cleat or device is so made that it will automatically
and firmly hold cords wires or the like of all sizes from the largest to the finest.
According to my invention the cord wire or the like is held between a fixed surface
and a moveable cam piece which has teeth or serrations which consist of ribs situated
transversely to the bearing surfaces that is extending from side to side thereof. The
fixed surface against which the cam face bears may be similarly toothed or serrated or
be left plain.
The accompanying drawing represents a cleat or device made according to my
invention. Fig. 1 is a perspective view Fig. 2 is a section on the line 1. 2 Fig. 3
and Fig. 3 is a section on the line 3. 4 Fig. 2.
A is the body portion consisting of the part a by which the article can be secured
to any desired place or object (by screws or otherwise) and of a side cheek a² the
parts a a² being connected by the stop pin d and by the piece a which constitutes
the fixed surface between which and the cam B the cord wire or the like is jammed
and held. The said cam B is centered on the pin 6 and so arranged that when the
tail piece is in the position indicated in Fig. 2 the surface of the cam B just
touches the inner surface of a³.
By drawing out the tail piece the cam B is turned on its centre to release its
hold of the cord wire or the like. The surface 63 of the cam B is provided with teeth
or serrations which are disposed transversely that is they extend from side to side of
the cam as shewn.
The pin d prevents the cam B from being brought to such a position that it will
not fall automatically.
The interior surface of the part a³ may be either left plain or it may be corrugated
or toothed similarly to the cam when the cleat is fixed perpendicularly the tail piece b³
falls into the position shewn in Figure 2 and when the cord wire or the like c is
passed between a³ and B as shewn in Fig. 1 the upward pull by reason of the teeth
or serrations causes the cam B to turn and this causes the cord wire or the like
however fine it may be to be jammed and held firmly between the cam B and the
inner surface of a³ and the greater the pull the more tightly it is jammed and held.
A downward pull causes the cam B to turn on the centre band release the cord wire
or the like. Instead of the cleat being attached by the part a as shewn in the
drawing the piece a³ can be extended and the cleat be attached by screws or other
fastenings passed through a³. When the part a³ is used as the attaching plate the
part a may be reduced to the size and shape of the part a².
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
A cleat or device for fastening or holding cords nisture wires of the like consisting

page_text: of or containing a cam provided on its bearing face with teeth or serrations
disposed as described and shewn and a fixed surface between which and the said
teeth or corrugations the cord wire or the like is jammed and firmly held.
