I, ALBERT E. AYERS MCCLURE Machinist Ledalia, Pettis County, Missouri, United
States of America do hereby declare the nature of my invention for CLAMPS, 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 a cord and rope fastener and is designed for use on paper,
bill and document files, shawl straps, book holders, to hold clothes lines, and awning
ropes, and a variety of other uses.
The object of the invention is to provide at a slight cost a clamp of the character
mentioned which shall be cheap and simple in its construction, light and durable, and
one that will allow the rope to be readily and easily clamped, and detached, when
desired, and yet which will hold the rope firmly and securely against accidental
detachment or slipping.
With these ends in view the invention consists in the improved construction and
combination of parts hereinafter fully described and pointed out in the claims.
In the drawings-
Figure 1 is a perspective view showing the device in use upon a book holder or
carrier.
Fig. 2 is a similar view showing it applied to a file holder.
Fig. 3 shows the device in use as a sack fastener.
Fig. 4 is a view showing the device adapted for holding awning ropes, and clothes
lines.
Fig. 5 is a detail view of the device detached.
Figs. 6 and 7 are sectional views on the lines x- and y-y of Fig. 5, and
Figs. 8 and 9 are detail views of modifications.
Corresponding parts in the several figures are denoted by the same letters of
reference.
Referring to the drawings, A represents a plate, which is preferably cast of any
suitable metal. This plate A is recessed or cut away at its end as shown at
a, to form
a slot b. Said plate A is also recessed on its upper face at one side thereof, as shown
at c, and in said recess is journaled a shaft C.

page_text: D represents a plate which is provided at one end with downwardly-extending ribs
or lugs d, which are formed with holes or openings for the passage of the shaft C,
upon which the plates D is journaled.
E represents a spiral spring which is located on the shaft C, and which has one of
its ends secured to the plate A, or bearing against said plate, and its other end fitting
in a notch in the plate D, which is not shown. By this means the force of the spring
causes the plate D.to be held at all times in the position shown. The plate D has an
inclined front face, which is preferably serrated, as at a', and which allows the rope to
be slid to the end of the plate. The end of the plate, like the inclined side, is
serrated as at 62, and said end rests in a recess e, and is prevented from downward
nfovement below a point on a horizontal plane with the upper face of the plate A, by
a shoulder f, on which the end of the plate D rests or bears.
In the modification shown in Fig. 8, the spring-actuated clamping plate D is
recessed at its inner end or heel, and said inner end or heel made square or nearly so
as shown to serve as a stop in case of great strain.
Fig. 9 illustrates another modification in which the device is adapted for use in
connection with curtain and mosquito-bar cords. In this case a headed screw E²,
which has a projecting headed piece E³. The clamping plate I) in this case consists
of two parts, and is journaled on the upper side of the head of the screw, and extends
upwardly therefrom, the parts being located on opposite sides of the headed piece E³
and adapted to bear against the same at their upper ends.
In operation, the cord or rope is placed in the recess u, and the plate D will be
slightly raised to permit the passage of the rope or cord to the end of the plate, which
when the rope is in place, is forced against and wedges the same by means of the
spiral spring. It will be observed that the greater the strain upon the rope or cord
the tighter it will be wedged, and that it cannot possibly slip since the face of the end
of the plate is serrated.
It will be obvious that the device before described can be used to advantage as a
clamp for ropes upon awnings, can be used as a substitute for cleats upon small boats
where it is necessary to make the ropes fast, can be used as a clamp for shawl and
book holders, file and bill holders, and is also adapted for a variety of uses.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is-
1. The combination with a plate having a recess, of a pivoted plate adapted to clamp
a cord or rope, substantially as described.
2. The combination with a recessed plate, of a spring-actuated plate adapted to
clamp a cord or rope, as set forth.
3. The combination with a plate having a recess, of a pivoted plate having an
inclined serrated face, substantially as set forth.
4. The combination with a plate having a recess and a shoulder, of a spring-actuated
plate pivoted to the first mentioned plate and having a serrated edge or face, as set
forth.
5. The combination with the plate A, having the recess, of the spring-actuated plate
pivoted to said plate A, the spring-actuated plate having an inclined serrated edge or
face, and a shoulder on the plate A, on which the end of plate D rests, as set forth.
Dated this 10th day of July 1886.

In the drawings, (which were sent up with Provisional Specification)
Figure 1 is a perspective view shewing the device in use upon a book holder or
carrier.
Figure 2 is a similar view shewing it applied to a file holder.
Figure 3 shews the device in use as a sack fastener.
Figure 4 is a view showing the device adapted for holding awning ropes and clothes
lines.
Figure 5 is a detailed view of the device detached.
Figures 6 & 7 as sectional views on the lines - and y-y of Figure 5.
Figures 8 & 9 are detail views of modifications. Corresponding parts in the several
figures are denoted by the same letters of reference.

at c and in said recess is journaled a shaft C.
D, represents a plate which is provided at one end with downwardly extending ribs

which the plate D is journaled.
E represents a spiral spring which is located on the shaft C and which has one of its
ends secured to the plate A, or bearing against said plate, and its other end fitting in a
notch in the plate D which is not shewn.
By this means the force of the spring causes the plate D to be held at all times in
the position shown. The plate D has an inclined front face which is preferably
serrated as at a¹, and which allows the rope to be slid to the end 6' of the plate. The
end of the plate like the inclined side is serrated as at 62, such serrations being made
at any suitable angle, and said end rests in a recess e and is prevented from downward

page_text: movement below a point on a horizontal plane with the upper face of the plate a, by a
shoulder f, on which the end of the plate D rests or bears.
In the modification shown in Figure 8, the spring actuated clamping plate D is
recessed at its inner end or heel, and said inner end or heel made square or nearly so
as shown to serve as a stop in case of great strain.
Figure 9 illustrates another modification in which the device is adapted for use in
connection with curtain and mosquito bar cords. In this case a headed screw E³
which has a projecting headed piece E³. The clamping plate D in this case consists
of two parts and is journaled on the upper side of the head of the screw and extends
upwardly therefrom the parts being located on opposite sides of the headed piece E³
and adapted to bear against the same at their upper ends.
In operation the cord or rope is placed in the recess a and the plate D will be

when the rope is in place is forced against and wedges the same by means of the spiral
spring. It will be observed that the greater the strain upon the rope or cord the

the plate is serrated.
It will be obvious that the device before described can be used to advantage as a

where it is necessary to make the ropes fast, can be used as a clamp for shawl and
book holders, file & bill holders and is also adapted for a variety of uses.

2. The combination with a recessed plate of a spring actuated plate adapted to
clamp a cord or rope as set forth.
3. The combination with a plate having a recess of a pivoted plate having an
inclined serrated face substantially as set forth.
4. The combination with a plate having a recess and a shoulder of a spring actuated
plate pivoted to the first mentioned plate and having a serrated edge or face as set
forth.
5. The combination with the plate A having the recess of the spring actuated plate
pivoted to said plate A, the spring actuated plate having an inclined serrated edge or
faco, and a shoulder on the plate A, on which the end of plate D rests as set forth.
