The subscriber has been IA years engaged I'm
manufacturing and putting springs into windows
land disposed Of about so OO and made use Of seve
raj different kinds for letting upper sash down. but
none heretofore so simple, durable, and convenient
as the plan now adopted, and herewith exhibited
Tor which he has secured Letters Patent Of the u s.
lie therefore hatterS himself that he has arrived At
such n degree Of perfection in said business as he
presumes will admit Of but little Improvement.
Small and middle sized windows properly fixed
with springs, are but little, If any, inferior 20 being
hung with weights; they are by many preferred, as
they cannot be opened on the outside, and the
springs obstruction to their being took out for
cleaning, glazing, painting, &c, and cost from 90 TO
80 per cent less. There are many advantages in
having upper sash TO let down, not generally appre-
cated nor thought Of, for want Of il PRODUCTION Bv
a number Of persons breathing in The same room,
the AIR becomes deprived of its oxygen, winch rem

and lighter, ascend the upper sash being let down

time the lower sash being raised small distance,
consequently current Of fresh air passes in 10 fiji

adding 10 health aud comfort. Churches, seminal
rieS, School-rOOms, &c, should invariably have the
upper sash TO let down, crowded house even i'm
cool weather, requires ventilation and if the lower
sash be raised, persons sitting the windows are
almost certain Of taking cold which would be avoid
ed by lowering the upper sash. Bcd-chambcrs
should always have the upper sash "a let down /;
kitchen windows to let smoke, steam from cook
ing, &c. Upper stories, used dwellings TO pre-
vent the danger Of children falling out. Likewise
manufactures. 1t also makes windows more con-
Nenient Tor cleaning, &c. There are many other
advantages IN having saSheS fixed o. raise or lower
TOO numerous to detail many Of which, upon little
reflection, will readily prcsen; themselves
window frames should he made with PARTING
( beads about 3-S Of an inch thick The protection
corresponding IN thickness with the parting bead
should ONLY be ON the meeting rail Of the lower sash
BON SaSheS should be the SIZE and the breadth
OF thc glass not exceed twO-thIuS its lcugth IL any
variation IN favour of the length. This IS much the
best plan OF making windows, and in general costs
no more than without parting beads.

for putting in properly.
Persons purchasing Springs should be careful TO
get the appropriate numbers.
