AUGUST JOHNSON AND JOHN D. CAHILL, OF McNEIL, TEXAS, ASSIGNORS OF
ONE-THIRD TO A. F. MARTIN, OF SAME PLACE.
TIRE-TIG HTEN ER.
SPECIFICATION forming part of Letters Patent No. 600,479, dated March 8, 1898.
Application filed April 20, 1897, Serial No. 6a3,041 (No model.)
To all whom it mzay concern:
Be it known that we, AUGUST JOHNSON and
JOHN D. CAHILL, citizens of the United States,
residing at McNeil, in the county of Travis
5 and State of Texas, have invented a new and
useful Tire-Tightener, of which the following
is a specification.
Our invention relates to tire-tighteners,and
particularly to a spoke-socket and means for
i adjusting the same to take up looseness of
both spokes and felly; and the object in view
is to provide a simple and compact construc-
tion and arrangement of parts adapted for ap-
plication to a spoke of the ordinary construc-
15 tion without material modification, such or-
dinary construction of spoke involving a com-
paratively uniform diameter from the hub to
the shoulder, which is adapted to bear against
a washer on the inner surface of the rim or
20 felly, a tenon extending centrally from said
shoulder and fitting in a mortise in the rim.
We are aware that spoke-sockets having ad-
justable parts to provide for tightening the
rim as well as the spokes have been used here-
25 tofore; but, as above indicated, it is our ob-
ject to construct a device of this class with
such a relative arrangement of parts as to be
applicable to a spoke of the ordinary con-
struction without shaping it specially to suit
30 the socket.
In carrying out our invention we employ a
sleeve or socket portion of an interior diam-
eter corresponding with the diameter of the
contiguous end of the spoke and having a re-
35 duced tubular extension for the reception of
the tenon, said extension closely fitting the
tenon and extending therewith into the mor-
tise in the rim. Thus the shoulder between
the end of the body portion of the spoke and
40 the tenon bears against the offset between the
body portion of the socket or sleeve and its
extension, thereby covering the end of the
grain to prevent moisture from reaching the
same and also forming a firm bearing for the
45 end of the spoke, such bearing remaining the
same in all adjustments of the parts from the
fact that the adjusting devices are applied ex-
teriorly to the sleeve or socket and serve to
adjust the sleeve without affecting its posi-
50 tion with relation to the spoke.
Other objects and advantages of this inven-
tion will appear in the following description,
and the novel features thereof will be particu-
larly pointed out in the appended claim.
In the drawings, Figure 1 is a side view of 55
a spoke-socket constructed in accordance with
our invention. Fig. 2 is a sectional view of
the same. Fig. 3 is a detail view of the same
Similar numerals of reference indicate cor- 6o
responding parts in all the figures of the draw-
The body portion of the device embodying
our invention consists of a tubular socket or
sleeve 1 of a diameter adapted to receive the 65
outer end of the body portion of a spoke 2,
and the outer end of this sleeve is contracted
to form a tubular extension 3, interiorly pro-
portioned to receive a tenon 6, integral with
the spoke and of the ordinary construction 70
well known in the art, said extension 13 be-
ing adapted to fit in the mortise formed in
the rim 5 of a wheel for the reception of the
spoke-tenon. Obviously said mortise must
be slightly counterbored to receive the exten- 75
sion 3, but otherwise the contruction remains
the same as when the shoulder or offset at the
outer extremity of the body portion of the
spoke bears against the inner surface of the
rim with only a washer or its equivalent in- 8o
terposed. In the construction illustrated we
have shown a washer 9 arranged between the
offset outer end of the sleeve 1 and the inner
surface of the rim, said washer being prefer-
ably spurred to engage the surface of the rim 85
and being fitted around the tubular extension
3 of the sleeve.
From the above description it will be seen
that a spoke of the ordinary construction may
be fitted into the sleeve or socket portion of 90
the improved tire-tightener without modifi-
cation as to either construction or propor-
tions, and that when thus seated the end of
the grain at the shoulder between the body
portion and the tenon is completely covered, 95
and thus protected from moisture to avoid
the decay incident to such exposure, as is also
well known in the art. Furthermore, the ex-
tension 3 protects the tenon to a point well
within the mortise of the rim and at the same moo
time is adapted to bear a large proportion of
the strain applied to the tenon by reason of
