Description
ihttrh' iiurt Letters Patent No. 111,742,
To Il whom -z' t may concern Be it known that I, CHARLES Brooklyn, in the county of Kings a York, have invented a new and ment in Vacuum and other Pumps, oi' which the i'ollowing is a full, clear, and exact description, reference being had to the accompanying drawing forming part oI this specification, and in which- Figure 1 represents a longitudinal section ot' a pump having my improvement applied to it.
Figure 2, a transverse section of the same.
Figure 3, au interior face view, on a larger scale, i ot' one of the valve-box lids o1' covers removed; and
Figure 4, a longitudinal section thereof.
i Y .Similar letters of reference indicate corresponding i parts.
)Iy'invention is mainly designed to be applied to l y pumps which are tted with a. multiplicity of valves Y 'arranged to act in concert at opposite ends ot tho i pumps cylinder alternately, in contradistinction to i single, receiving and deliveryvalves having an arca equal to that ot' the combined area of the many-valve i arrangement, which. latter is more sensitive or quick in its action and better adapted to the obtainment ot' i a perfect result, as in the case of pumps for working vacuum-pans in the manufacture of sugar, for which purpose a high range ot vacuum is requiredor desiri able. `One great dithculty in such vacuum-pumps has .Y o, ,.been the inaccessibility ofthe valves and valve-seats, or impossibility of their removal without disturbance ofthe pump, which is inconvenient, laborious, and expensive, occasioningmuch waste'of time, and being otherwise objectionable. ,A read'yaccessibility and removal of the valves, together with`their seats, withont disturbing the pump-cylinder and its other workl ing parts, and this, too, so that the several valves and their seats in a series may be taken out collectively i tu discover' any defect in the action of one or more of them arising from clogging or otherwise, is, accord', l ingly,veny desirable. This my invention accomplishes li I in a very simple and eicient manner by so constructing the bonnets or covers of the valve-boxes as that .they carry the valves, and have the valve-seats ari ranged in connection with them, whereby, on simply l detachi@ from the eylindel` of the pump a bonnet or cover to one of the valve-boxes1 a series ot' valves, t
with their seats, is simultaneously removed; and
Furthermore, the invention includes a combination, I with .such an arrangement, of a single valve-guiding and spring-holding or base-bar to the several valves in a series, so that, on merely releasing said bar at its opposite endsfrom connection lwith the bonnet or cover, the whole otithe valves may be separately removed from their seats. A
B. HARDIGK, of nd State of New useful Improve Referring to the accompanying (drawing-e i CHARLES B. HARDICK, OF BROOKLYN, NEW YORK double inlet-connections a a., for working vacuum cylinder,
dated February 14. 1871.
IN AIR-PUMPS.
The Schedule remi-red to in these Letters Patent and making part of the same.
A represents the cylinder ot' a vacuum-pump, arranged to occupy a horizontal position, and having pans, inletpump is merely -pan or pans on on bothA or opposite sides of it; but a single connection only maybe used where the required to connect with a vacuum one side of it.
i is the reciprocating piston, arranged within said cylinder, and operated by anyr suitable means. C G nrc the rcceivingwalve boxes or chambers arranged on the lower side ofthe cylinder, and com inunicat-ing, by openings b l, with the cylinder A at SOlDOsite ends, also connecting, through Ithe valve- .box lids or covers D D, with passages c o, that are in t'ree communication with the inlets a a.
Each of these valve-box covers D has the seats 1l (l of a series of puppet-valves f f formed in them 'or in a plate, Q, fitted thereto, the openings in or through said seats establishing communication, byor through a passage, 11, made in the cover, between the receiving-valve box or chamber G and passages c, in connection {vith which such set or series of valves is arranged to operate.
These valves ing their stems 'i 'i to play through guille-l1oles in the valve-seats and apertures in a guiding-bar, E, which latter is common to the several valves-iu the series, and serves as the base-bar for the valve-closing springs 7c k to bear against, said bar resting at its opposite ends on stanchion's or projections l l iiom 0r attached to the valve-covers, and being;` secured thereto by nuts 1nm.
The delivery-valves f' f' on the upper side of the and which control the outlet-passages b'.b, nia-y be similarly carried by their bonnets or covers D' D', that. communicate with passages c e', which open into a general outlet, a; but the seats d d' are here shown as connected with the cylinder ot' the pump, and the construction or arrangement ot' parts otherwise different from that of the receiving-valves, as it is only necessary for. the purpose of illustrating the improvement to show my invention as applied tov certain of the valves.
From this description it will be seen that every facility' is afforded, without disturbing the pump, by merely taking otf either valve-bonnet or cover lt'roin the cylinder, for lifting out and removing, collec 'vely, the several valves f f and their seats d (l in a series, as examination, repair, or removal of an obstacle may require, and that, by unsclewing the `nuts m m., the valve-guiding and spring-holding bar Emay be disconnected for the purpose of separately removing. any one or more of the valves or getting at their seats.
In working the pump it isedesirable to-introdnce a little water into the inlet-passage or passages to fill f fare steadied and guided by arrangthe space left between the head of the piston and end of the cylinder at each termination ofthe stroke, and to seal the valves, also, to prevent heating. Should such water he admitted in quantity greater than necessary for these purposes, such surplus will he discharged through the deliver\'valves.
lVhat is here claimed, and desired to be secured by Letters Patent, is-
1. The valve-box lid or cover D, formed with the valve-seats (l :l in it, and with a suitably-arranged y passage, h, through it, in combination with a series of valves, ff, carried by said lid or cover, and for operation iu relation to the seats dll substantially as specied.
