COMPLETE SPECIFICATION.
Improved Anti-rattlers for the Shaft or Pole Couplings of Vehicles.
1, CLARENCE AGUSTUS CARMAN, of Wyanlance, in the County of Suffolk and
State of New York, United States of America, Farmer, do hereby declare the
nature of my invention for anti-rattlers, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The invention relates to anti-rattlers in which provision is made for adjusting the
spring to increase its pressure on the thill when desired, or to relieve the pressure in
removing or replacing the thill; and the object of the invention is to provide an
efficient device of this character of stable construction and neat appearance.
To this end the invention consists in the novel construction and combination of
parts, as hereinafter described, and defined in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1 is a side view of my invention as applied to an axle-clip and thill.
Figure 2 is an inverted plan view thereof.
Figure 3 is a front view, the thill being omitted and the supporting brackets thereof
being in section on line a a, Fig. 1.
Figure 4 is a vertical section on line y y, Fig. 3.
Figure 5 is a side view of a modified anti-rattler, the same being represented as it
appears when in a position for use in connection with a thill coupling.
Figure 6 is a face view of the modified form of attachment, the thill coupling being
shown in section.
Figure 7 is an inverted plan view thereof; and
Figure 8 is a sectional view on line 4, 4 of Fig. 6.
The axle-clip A shown is of ordinary form, having forwardly-extending brackets or
arms a a, that form bearings for the securing-bolt 6 of the thill B.
In constructing my improved device a plate C is provided which is adapted to rest
on the brackets a a of clip A, and is formed with depending arms (, from the
forwardly-extending lower ends of which the spring D of the device is pivotally
supported-as, for instance, through the medium of a plate D¹, which is formed
integrally with or secured to the spring D, the pivot-pin d of the connection passing
through said plate D' and through the ends of the depending arms C₁ C.
2,
Supported from the plate C is an adjustable hanger E, which is formed with a
threaded upper end which passes through an aperture in the plate C, and is engaged
above said plate by a nut E'. The forwardly-extending lower end of the hanger E
is connected with the inner end of the plate D' by a pivot-pin d'. With this con-
struction as the hanger E is moved upwardly by the manipulation of the nut E¹ the
spring will be forced against the thill B, the plate D¹ swinging on the pivot d. The
spring D is slotted at its free end, as at d², to allow it to clear the hanger E when
moving away from the thill B.
The modified construction shown in Figures 5, 6, 7 and 8 is substantially the same
as the construction shown in the first four figures of the drawings and described
above; but instead of using a spring-supporting block or plate D', I form the spring
from a single length of wire that is coiled upon the cross-bar or pivot d, between the
arms CC, the central portion of the wire being carried backward in the form of a
loop 5, while the ends of the wire are carried backward and upward and form spring
arms 6, 6. The adjustable hanger E is connected to the loop 5, and although this
hanger or adjuster could be made in any proper way, I greatly prefer to make it from
malleable iron, making the lower end in the form of an open hook, as 7, which hook

page_text: may be readily brought into engagement with the loop 5, and then the end of the
hook may be forced down to the position in which it is shown in the drawings.
In operation the anti-rattler is adjusted as represented in the drawings, and then
when the shafts or thills are to be changed the adjuster or hanger is lowered, and in
being so lowered the spring arms will be carried to the rear, thus providing for the
easy adjustment of the thill iron eye, as will be readily understood.
As the parts of the clip become worn, or the tension of the spring arms diminishes,
the adjuster or hanger is slightly raised, and the arms will thus be thrown forward
and will act with greater effect upon the thill iron.
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 an anti-rattler, the. combination, with a plate, of a hanger adjustably
supported from said plate, and a spring pivotally connected with the said banger,
substantially as described.
2. The combination, with the plate C, having depending arms CC, of a spring D,
pivotally supported from said arms, and the adjustable hanger E, acting to adjust
said spring, substantially as described.
3. In an anti-rattling attachment, the combination with a frame, of a spring wire
coiled thereon and formed with upwardly-extending arms, and a means for adjusting
the arms, substantially as described.
4. In an anti-rattling attachment, the combination with a frame, of a spring wire
coiled thereon and formed with a rearwardly-extending projection and with upwardly-
extending arms, and an adjuster connected to the rearwardly-extending projection
of the spring wire and extending upward and through the upper portion of the
frame.
5. In an anti-rattling attachment, the combination with a frame, of a spring wire
coiled thereon and formed with a rearwardly-extending projection and with upwardly-
extending arms, an adjuster, formed with a hook-like lower end, which end engages
the rearwardly-extending projection of the spring wire, and with an upwardly-
extending stem that passes through the upper portion of the frame, substantially as
described.
