PROVISIONAL SPECIFICATION.
Improvements in Thrust Blocks and other Bearings, and in the
Shafts to which the same are applied, applicable in connection
with Propeller Shafts.
1, HENRY LAMB, of 22 Battle Road, Erith, in the County of Kent, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in shafts to thrust blocks or bearings
applicable to marine screw propeller shafts, which I intend to use in conjunction
with a Patent granted to me No. 1991, bearing date February 6th, 1890; and has
for its object the prevention of excessive friction on the shafts and for the adjust-
ment of the shafts of marine screw propellers or other purposes.
I construct the propeller shaft with a swell and over this swell I place a frame of
suitable metal, and of a circular form to any required dimensions. This frame is
constructed in divisions with an outer and inner rim joined together by the boundaries
of the divisions as described in my Specification No. 1991, February 6, 1890.
If preferable the shaft may be made adjustable by halving two ends together, and
around the halvings I place a cylindrical collar, and above the collar and on the
shaft at each end of the collar I place the frame and other mechanism mentioned in
my Specification No. 1991, of 1890.
The aforesaid may be constructed in another way, viz. :-a long cylinder with a
hole in the centre at each end a short distance down the cylinder, with a shoulder
at each end of a reduced bore, so that the halved ends of the shaft may meet in the
reduced bore of the cylinder. At each end of the cylinder on the periphery I form
a thread in order to receive a large nut, these aforesaid nuts at each end are intended
to keep in position the circular frames or divisions, and in between the said frames,
rollers work on spindles passed from one frame to the other.
It will be understood that the foregoing is given by way of illustration, and that
the materials, parts and shapes, may be varied in many ways within the scope of my
invention.

tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of the bed a' cover a to enclose the frame h, and the rollers c
on the spindles bolted to the frame f by nuts b', the cover g and lock nut l, to enclose
the ends of the shafting d d with the bite or halvings e and indicator g³, substantially
as herein described and according to Figs. 1, 2, 3, 4, 5, 6, 7, and 10, of the accom-
panying drawings.
2. The combination of the bite e swell b on the ends of the shaft d d, with the
clips gl bolted together to form the coupling, substantially as herein described and
according to Fig. 8, of the accompanying drawings.
3. The combination of the bite e indentations kk in the ends of the shaft and the
block and the screwed coupling i with the nuts jj, for coupling all kinds of
machinery together, substantially as herein described and according to Fig. 9, of
the accompanying drawings.
