THOMAS STEPHEN KEMP, OF CLARENDON, TEXAS.
PUMP-ROD COUPLING.1,067,819.
Specification of
Application iled December 2To all whom it may concern:
Be it known that I, THOMAS S. KEMP, a
citizen of the United States, residing at
Clarendon, in the county of Donley and
5 State of Texas, have invented a new and
useful Pump-Rod Coupling, of which the
following is a specification.
This invention relates to a pump rod
coupling and more particularly to a cou-
10 pling adapted to connect together pump rods
made of wood or similar substance.
An object of the invention in to provide
an improved form of coupling in v-hich the
ends of the rods to be coupled are wedgedly
15 engaged by the coupling member and the
ends of said rods prevented from spreading
by means of suitable ferrules.
With the foregoing and other objects in
view which will appear as the description
20 proceeds, the invention resides in the com-
bination and arrangement of parts and in
the details of construction hereinafter de-
scribed and claimed, it being understood
that changes in the precise embodiment of
25 the invention herein disclosed, can be made'
within the scope of what is claimed, with-
out departing from the spirit of the in-
vention.
In the drawings accompanying this speci-
30 fication and forming a part thereof, the
preferable form of my invention is illus-
trated, in which:-
Figure 1 is a view in elevation of my im-
proved coupling secured to the ends of suit-
35 able pump rods. Fig. 2 is a vertical cross sec-
tional view of the same in which the various
parts have been detached. Fig. 3 is a de-
tail view of one of the rod engaging mem-
bers. Fig. 4 is a detail view of one of the
40 ferrules.
Referring to the drawings in which simi-
lar reference numerals designate correspond-
ing parts throughout the several views, 1
and 2 are the ends of wooden rods which are
45 to be coupled. In the application of my
improved coupling to the ends of these rods,
they are provided with the transverse cy-
lindrical bores 3 and 4 communicating by
the restricted passage 5. Extending down-
50 ward from the bore 4 is the restricted pas-
sage 6, the latter flaring outward adjacent
the end of the rod. As has been illustrated
in the drawings both the rods 1 and 2 are
similarly formed.
55 'The ends of the rods are'turned or cut on
a -bevel to form the frusto - conical er ls.Letters Patent. Patented July 22,1913.
0;1912. Serial No. 737,902.
Adapted to fit within the bored opwiuings
and restricted passage of the rod ends are
the members formed with the lugs 7 and
8 connected by the web 9. Exteriding from go
the lug 8 is the web 10 which is.tlared out-
wardly to conform with the passage 6 'and
terminates in the threaded. portion 1:.t As
illustrated in Fig. 3 the edge' of this iinm-
ber is inclined and rounded in order-to con- 65
form and lie flush with the.outer surface
of the rods 1 and 2. By reason of the en-
larged lugs or bosses 7 and 8 fitting wither
the respective openings 3 and 4, a secure.
grip or hold is obtained upon the rods 1 7o
and 2. In order to prevent the ti-nos of the
rods 1 and' from splitting and being forced
outward, a suitable ferrule as illustrated.
in Fig. 4, is provided which fits upon the
frusto-conical ends of the-rod Iand 2. The 75
said ferrule is shell-likeir5 form and frusto-
conical in configurationaiid fits snugly upon
-the end of the rod andprevents the ttach-
ing ends of the, rods from moving trans-
versely thereof.In this connection it is to 80
be understood that the lugs 7 and 8 with the
webs and threaded ends ae first forced into
position within the openings formed in the
rod ends after which the ferrule 12 is in-
stalled in position. Having thus provided 85
attaching means for gripping the wooden
rod ends in order to secure and couple the
threaded projections or ends 11 together, the
coupling member 13 is provided with the
internally threaded ends 14 and 15. The 90
central portion of this union or coupling
member is solid and the outer surface of
which may be milled to form a suitable
wrench engaging surface. A second cou-
pling member 16 is provided with the 85
threaded plug 17 and the internally thread-
ed socket 18, the threads in this coupling
being both preferably right-handed ones.
The socket 18 threadedly engages the por-
tion 11 of the rod attaching member. . 100
In the assembling of my improved cou-
pling, the rod attaching members with their
transverse extending lugs are first inserted
in the ends of the wooden rods. The fer-
rules 12 are then positioned thereon. The 105
union member is then screwed upon the por-
tion 11 which threadedly engages the socket
14. Attention is called to the fgct ii this
connection that the diameter of the union
is sufficient to extend over the end of the 110
ferrule and hold the latter fir' ly in posi-
tion. The plug and socket member .6 is
