"IMPROVEMENTS IN
LUBRICATORS FOR WHEELS FOR VEHICLES." A communication from abroad by
Francis William Carpenter, of Rye, Westchester County, State of New York,
United States of America.
The nature of my Invention consists in the construction and arrangement of a
lubricator for wheels for vehicles combined with a nut locking device for the same,
or for other places where the same may be applied, as will be herein-after more fully
set forth.
In order to enable others skilled in the art to which my Invention appertains to
make and use the same I will now proceed to describe its construction and operation,
referring to the annexed Drawing, in which Figure 1 is a longitudinal section of my
lubricating device; Figure 2 shows the piston, which forms part thereof.
Figure 3 shows part of my Invention applied as a nut lock.
A represents a tube of any suitable dimensions, provided at its inner end with a
nipple B having exterior screw threads. This tube is further, near its upper end,
provided with a plate or flange C projecting all around the same. To insert this
tube in the hub of a wheel a hole is bored through the hub D and a smaller one
through the box E, which latter hole has female screw threads for the nipple B to
screw into. The hole through the hub must in many cases be larger than the
outside diameter of the tube, to allow the nipple to enter the hole in the box, and
hence the tube will not be held rigidly in the hub but be liable to come loose. To

page_text: obviate this and other difficulties I have provided the tube with the flange C above
mentioned, so that when the tube is inserted and the nipple screwed into the box,
this flange will lie close to the outside of the hub, and is then fastened thereto by
screws, nails, or other suitable means. By this means the tube A is held firmly in
place and cannot come loose, and at the same time it compresses a washer a placed
around the nipple between the box and lower end of the tube, so that there can be
no leakage of oil in between the box and hub. It will thus be seen that, even if
the thread on the nipple should become worn or otherwise injured, the flange C
holds the tube firmly in its place, and also causes a firm and oil-tight joint at the
inner end. The lower end of the tube A is reamed out to form a chamber b a trifle
larger than the bore of the tube, as shown in Figure 1. G represents a piston
packed in any suitable manner to fit the interior of the tube A, and provided with
a stem H extending upwards through the tube and a point I extending downward
into the nipple B. On the upper end of the stem H is fastened a cap J, to be
screwed on to the upper end of the tube A. After the tube A has been inserted
and fastened in the hub, as above described, the tube is filled with oil, and by
inserting the piston G in the tube and forcing it down the oil is forced down
through the nipple B in between the box and the axle. This operation may be
repeated, if necessary, till a sufficient quantity of oil has been injected; the piston
is then pressed down into the lower end of the tube and oil poured on top of the
same, after which the cap J is screwed down tight, a washer d being placed within
the cap to form an oil-tight joint. When thus screwed down the piston G is within
the enlarged chamber b at the lower end of the tube and the point I passed through
the nipple B. As the axle becomes hot the oil in the tube passes around the
piston G, through grooves or channels in the lower face thereof, and between the
point and nipple to the axle. The point I prevents the nipple from becoming
clogged with gum, etc. The cap J on the upper part of the stem H is formed with
a thumb piece J¹ for screwing and unscrewing the same. To prevent this cap from
becoming loose or injured by being knocked against anything I provide a cover L
of globe shape hinged to the flange C at one side and fastened at the opposite side
by a suitable spring catch h. When this cover is closed it comes close down on the
thumb piece J, and of course prevents the same from turning. This lubricator
may be applied to other places or machinery as well as to wheels, wherever a
lubricating device is needed.
The cap L may be used as a nut lock, as shown in Figure 3, wherever such a
device may be needed. In this Figure P is an ordinary bolt; R, the nut; and C¹
a washer plate, bar, or other article placed under the nut on the bolt. If, according
to the situation of the plate C¹ it cannot turn, then it need not be fastened, other-
wise it is to be secured by screws, needs, or other means, and the cap may be hinged
or otherwise secured to said plate. The interior of the. cap is made round and
tapering upwards, so that in whatever position the nut may be placed the cap, when
closed, will bind on the upper corners of the nut and hold the same firmly in place.
If the cap should not thus bind it will be seen that the nut cannot unscrew on
account of the tapering form of the cap. Interior thimbles may be used to adapt
the cap to different sized nuts. It is not essentially necessary in a closed cap that
it should be tapering; if the cap however is open at the top it should be made
tapering.
Having thus fully described my Invention, what I claim as new and desire to
secure by Letters Patent is,-
1st. In a lubricator the combination of the tube A with screw nipple B, and a
piston working within the tube above the nipple, for the purposes herein set
forth.
2nd. In a lubricator the tubular chamber A provided with the screw nipple B
and flange C, substantially as and for the purposes herein set forth.
3rd. The combination with a hub D and box E of the tube A, the screw nipple B,
with packing a around the same, and the flange C, substantially as and for the
purposes herein set forth.

page_text: 4th. The piston G with stem H, cap J, and point I, in combination with the
tube A having enlarged chamber 6 at its lower end, substantially as and for the
purposes herein set forth.
5th. The globe-shaped cover L in combination with the tube A, flange C, and
cap J, with thumb-piece J¹, substantially as and for the purposes herein set
forth.
6th. In combination with a bolt and nut I claim a cap arranged to close over the
nut and end of the bolt, for the purposes herein set forth.
7th. The combination with a bolt and nut of the washer C¹ or its equivalent,
tapering cap L and holding device h, substantially as and for the purposes herein
set forth.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Fourth day of November, in the year of our Lord
One thousand eight hundred and seventy-six.
