. Bearings for Spindles.
PETER LANCÉ Needle Pointer Redditch County of Worcester do hereby
declare the nature of this invention to be as follows:-
This invention relates to the manner in which I construct the cheeks or bearings
for carrying revolving spindles with pointed ends for grindstones, emery stones or
wheels, polishing buffs and bobs, the object of my invention being to so construct
the checks or bearings that the ends of the pointed spindles are suspended and
revolve in anti-friction metal fixed by any convenient method.

Bearings for p
I, PETER LANCÉ, of Prospect Hill, Redditch in the County of Worcester,
Needle Pointer, do hereby declare the nature of my said invention and in what..
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to improvements in the construction of the bearings or
cheeks which carry revolving spindles with pointed ends, such as are employed for
grindstones, emery stones or wheels, buffs and bobs, used for polishing and such:
like purposes.
The aim and object of my invention being to reduce to a minimum the friction
and thus the wear given by these pointed spindles to the bearings when the said
spindles are in motion.
In needle pointing the mode hitherto employed for forming the bearings or
cheeks, for carrying the spindles, has been by oblong pieces of wood a required
length, rectangular in cross. section the inner ends (when in application) being.
turned down to receive two circular metallic ferrules the wood in the centre carries '
the pointed ends of the spindle, it will be readily seen that by the revolution of
the spindle in the bearings of wood by friction these spindles are soon out of centre,
by burning and wear so that a frequent change is required.
To remedy this is my invention, I will describe my invention to one of its many
purposes, viz. the construction of bearings for spindles of grindstones of the kind
employed in the pointing of needles, and other like articles.
employ two bars of metal of a required length, and rectangular in cross section
by preference the end of each bar that is the inner end is bored out and fitted with
plugs of antifrictional, metal, in a permanent manner, and these plugs of anti-
frictional metal are bored or formed to receive the two ends of the spindle with
pointed ends, one side of each bar has an hole in connection with the spindle, and
this is for lubricating.
These two bars when iu application rest in two troughs of a corresponding size,
and their movement for removal or adjustment is only effected upon a horizontal
line, the troughs being connected with the platten or standard which supports the
whole.

page_text: The grindstone which is grooved and employed in the pointing of needles, and
such like articles, is set upon the spindle in the ordinary way and engages to a
second wheel which finds its bearing (by being set transversely) in the groove of
the grindstone. The mode of imparting motion is effected by any well-known
means.
And in order that this my said invention may be more particularly described
and ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. I is a view in elevation of parts forming an apparatus to be employed in
the pointing of needles, with my invention applied thereto.
Fig. 2 is an end view of one part detached.
Figs. 3 and 4 are modifications of my invention.
a, a are two bars of metal of a required length, rectangular in cross section the
inner ends b, b, are bored and receive the antifrictional plugs of metal c, c, these
are bored or formed to receive the two pointed ends d, d of the spindle e, e as
bearings are views of the troughs (in section) in which a, a find their bearing,
and slide to and fro for adjustment of the bearings, these troughed parts f, fare
secured to the platten or standards g, g. is the grindstone, with groove i, and
jis the transverse wheel working in the groove i and is mounted upon the shaft l.
o is the hole for lubricating. The bars a a are secured to the troughed parts f, f,
or to the platten or standards g, g, by cramps, or in any other convenient
manner.
In Fig. 3 the bar a may be constructed of wood or other suitable material, upon
the inner end 1 should affix a metal cap m, fitted with the plug of antifrictional
metal C, for the points d of e to revolve in as above set forth.
In Fig. 4 the bar a may be of wood or other material, and upon the inner end
I should affix a plate constructed of antifrictional metal c for the points d of e, to
revolve in as above set forth.
I would observe in conclusion that I do not limit myself to the precise details
herein set forth and shown as I may vary or modify the same without departing
essentially from the principle of my said invention.
'
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 1
claim is :-
In "bearings for spindles'
"
1. The combination of bars of metal provided at their ends with antifrictional
metal as bearings, substantially as hereinbefore described and illustrated by the
drawings.
2. The combination "bars of other material than metal provided at their ends
with antifrictional metal bearings," substantially as herein before described and
illustrated by the drawings.
3. The general construction and combination of parts substantially as herein
