## THE USE OF THE TABLE OF

### SUPERFICIAL OR FLAT MEASURE, WHEN APPLIED TO GLAZIERS’ WORK OF ALL KINDS.

#### EXAMPLE I.

In a window of leaded glass which has three lights in it, each light being 3 feet long and 15 inches broad, I desire to know how many feet there are of glazing ?

First, add the length of the three lights together, which makes 9 feet, then look in the table for 15 inches, the breadth, and opposite the 9 feet, the length, you will find 11:5: 3, which is 11 feet, 5 inches, and 3 twelfth parts, the content of the three lights required.

#### EXAMPLE II.

In four windows of leaded glass, each window having two lights, and each light, being 3 feet 6 inches long and 17 inches broad, I demand how many feet there are of glazing ?

First, the length of all the eight lights must be added together, which make 28 feet 6 inches, then look in the table for 17 inches, the breadth. But since the table does not extend to 28 feet, the length, you must take the answer out at thrice, viz.

 F. I. P. S. 20 feet long, and 17 inches the breadth, is . . . . } 29 7 0 0 8 feet long, and 17 inches the breadth, is . . . . . } 11 10 0 0 6 inches long, and 17 inches the breadth, is . . . } 0 8 10 6 The content required . . . . . . . . . . . . . . . . . . . . . 42 1 10 6

So that four windows, each having two lights, and each light being 3 feet 6 inches long and 17 inches wide, contain 42 feet, 1 inch, 10 twelfth parts, and 6 seconds of glazing.

 – 183 – Measuring Glazier’s Work

Note.—If you have any quarters of an inch in the length, they must be found at the bottom of the table, and added as the inches are in this Example.

To measure Sash-squares this table is also very useful.

#### EXAMPLE III.

In a sash-window that has 12 squares of glass, (i.e. 4 high and 3 broad,) each square being 10 inches high and 8 inches broad, I would know how many feet of glass it contains?

First, add together the height of the 12 squares, which make 10 feet, then look in the table for 8 inches, the breadth, and opposite 10 feet, the length, is 6 feet, 10 inches, and 6 twelfth parts, which is the quantity of glass in the said sash-window.

Note.—If you have any odd inches, or quarters of an inch, in the length, you must proceed as in Example II.

#### EXAMPLE IV.

In a sash-window having 18 squares, each square being 20 inches high and l1 inches broad, I would know how many feet of glass are therein?

First, add together the height of the 18 squares, which is 360 inches (or 30 feet,) then look in the table for 11 inches, the breadth. But since the table does not extend to 30 feet, the length, you must take the answer out at twice, viz.

 F. I. P. 20 feet long, and 11 inches in breadth, is . . . } 19 7 0 10 feet long, and 11 inches in breadth, is . . . } 9 9 6 The content required is . . . . . . . . . . . . . . . . . 29 4 6

So that a sash-window that has 18 squares, each square being 20 inches high and 11 inches wide, contains 29 feet, 4 inches and a half of glass.

Note.— Observe that, for the generality, sash-windows have either 12 or 18 squares each, and in such a case the quantities are more easily and expeditiously found by the following method :—

When a window has 12 squares, the inches in height are to be conceived so many feet in length, as will more plainly appear by re-considering the foregoing Example III. where the 12 squares were each of them 10 inches high, and consequently, when added together, make 10 feet in length; so that by this method of conceiving the inches in height to be feet, the trouble and time in adding the 12 together is hereby saved, and the question more easily answered.

 – 184 –

Again, when a window hath 18 squares in it, if you conceive the height in inches to be feet, and take the con­tent as given by the table, and the half of that content, these added together will be the quantity; and this method will be very serviceable (if rightly un­derstood), for by this means you will rarely exceed the extent of the table, (few squares being more than 24 inches high, the bounds of the table in feet,) as for instance :—.

In Example IV. where the height of each square was 20 inches, and 11 inch­es broad, look in the table for 11 inches, and opposite 20 feet long (i.e. inches high) is 19 feet 7 inches, half of which is 9 feet 9 inches, and these being added together make 29 feet 4 inches, which was the content as given before on page 183.

Many more examples might be ad­ded to illustrate this rule, but a little application and practice will make it very easy and familiar.

A bundle of 4 feet oak-heart laths is 120, and 37 bundles is a load.

A bundle of 5 feet oak-heart laths is 100, and 30 bundles is a load.

Note.—Fir and deal laths are of divers length as 3, 4, 5, and 6 feet, but all of them are reduced to the standard length of 5 feet, and so every run of bundles (each bundle containing 100 laths) is a load, being equal to 30 bundles of 5 feet laths.
