IMPROVEMENTS IN VALVES
Year: 1884

page_text: I, ANDREW THOMSON of Millgate Works Rotherham in the County of York
Brass Founder do hereby declare the nature of my Invention for IMPROVEMENTS
IN VALVES to be as follows:-
.
My Invention consists first of an arrangement of several parts forming a perfect
Lubricator as Fig. 1-Fig. 2 is a cup for holding oil or tallow, and forming the
main part to which the parts hereinafter described are attached. Fig. 3 is a cup
or filler by which the Lubricator can be filled with oil or tallow without taking off
the cover, but by simply screwing down the spindle as Fig. 4 which has a left
hand thread so that in closing Valve attached to it Fig. 3 cannot be unscrewed.
The said spindle is fitted with a Loose Valve as Fig. 5, this valve is ground on both
Bides forming a perfectly tight joint. Fig. 6 is a Spindle for regulating the supply
of Oil or Tallow and is fitted with a rotary valve as Fig. 7 which is joined to
Fig. 6 by being spun over as shown in Fig. 1.-Fig. 8 is a stuffing box which is
screwed into Fig. 2 with a left hand thread as shown in Fig. 1, so that in opening
the valve with Fig. 6 Fig. 8 cannot be unscrewed-Fig. 9 a screw or packing ring
for keeping down packing in Fig. 8.-Fig. 10 a wheel of which there are two one
attached to filling spindle the other to regulating spindle.
Having thus described my said invention I would have it understood that I claim
for loose valve as Fig. 5 and its attachment to Fig. 4 as being original, also for
Rotary valve Fig. 7 and manner of attachment to fig. 6-I make no claim to any
of the other parts separately and the details may be varied without departing
from my invention.

page_text: I, ANDREW THOMSON of Rotherham in the County of York, Brass Founder do
hereby declare the nature of my invention for IMPROVEMENTS IN VALVES and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my Invention is to effect improvements in Valves for lubricators,
steam and water valve taps such improvements being more particularly applicable
to lubricators made in accordance with a certain Invention mentioned and described
in a previous application for Letters Patent dated 13th Nov 1884 No. 14985.
My Invention consists in the method of forming the screw valve and top valve
cover and connections whereby the same are rendered certain in action, durable,
and not liable to get out of order.
And in order that 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. 1. is a sectional elevation of our improved lubricator, and Fig. 2 is a detail
view of the several parts of the Valve. a. is the valve formed as a frustum of a
cone, having a pin a formed in one therewith--b. is a spindle, into the end of
which the valve a. is fitted by "spinning" the lip b¹ over the edge of a., as shewn
in Fig. 1-c is a tube, having screw threads inside and outside. c is a left handed
screw, fitting into the socket c³ (Fig. 1) c is a right hand screw fitting on to the
screw b. d is the gland and e is the gland cover, both of which are shewn in
position in Fig. 1. f. is a hand wheel for actuating the valve a and thereby
opening or closing the passage g. as desired.
The conical valve a is capable of rotating in the spindle b., when fitted as before
described, and as shewn in Figure 1, and thus a perfect fit to the soat is provided
for and secured, and no grinding of the surfaces can take place when the spindle is
being turned.
Fig. 3 is a view of the details of the top valve, cover, and connections; the
whole of which are shewn in position in Fig. 1-h is the cover, which is screwed
on to the main body of the valve, as shewn i is the cap which is kept in its place-
by the screw . and nut l., and is formed with an opening at m for the insertion of
the lubricant n. is a slide fitted with a knob o and capable of partial rotation
upon, as a centre-By means of this slide the opening m. may be covered or
uncovered p. is an inverted loose conical valve which fits the seat p¹, steam tight,
when screwed up. The upper part of the cap i carries a milled flange which is
used as a hand wheel to open and close the valve p, the screw k, being so fitted
that it revolves with the cap, and thereby operates the conical valve p. which
rotates on its spindle, as shown in the drawings.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1. The method of forming and mounting valves for the purposes aforesaid, with
loose plugs capable of rotating on their spindles and of self-adjustment to their
seats, substantially as hereinbefore described and shewn on the drawings.
2. The general arrangement, construction and combination of the several and
respective parts together forming my improvements in valves for lubricators
substantially as herein before described and shewn on the drawings.
