These are applied to the bottom rail of the lower sash to afford a hold for the fingers when raising the sash.

They should always be specified for plate glass windows and for all sash 3 feet wide and over.

Sash lifts are of four kinds: 1. The flush sash lift (see E, Plate III.), which is mortised into the rail of the sash so as to be flush, or nearly flush with it. 2. The hook sash lift, the most common style of which is shown in Fig. 430. This is about the most convenient shape to take hold of, and is the shape most largely used. 3. Bar sash lifts which are of the shape shown in Fig. E. Plate III., and may be obtained either plain or ornamented. For very heavy windows the flush or bar sash lifts are best, as several fingers can be inserted into the lift. The flush sash lifts are also neater in appearance. 4. Sash lifts and locks combined. One of the most practical styles of these combined sash lifts and locks is shown in Fig. 430a. The hook is fastened with a pivot and terminates in a second hook, which catches over a plate screwed on to the sill. The upper part of the lift is forced out by a spring. Flush lifts with lock catch may also be had if desired. These locks should be used where there is but one sash to the window, or when the sashes are hung with spring balances.

Fig. 431 shows a sash lift intended to go on the stile of the sash about half way up (made by the Wilier Manufacturing Co.), that is very convenient for the ordinary windows of residences, as it can be used equally as well for raising or lowering the sash; it will be found especially convenient on the upper sash, as well to lower it as to raise it.

Sash pull plates or sockets, being small brass plates with a round hole or socket, are often screwed to the top rail of plate glass windows for pulling down the sash. A pole is used for this purpose with a hook, called a sash pull, on the end of it which fits into the socket on the sash.

The use of sash pulls and sockets prevents the sash from being racked and strained and are a great convenience. They should be of solid bronze on all but the very cheapest work.

Stop Adjusters - It is becoming the custom in good buildings to secure the stop beads of the windows, and also of sliding doors with screws passing through an elongated hole in a round plate or socket let into the stop. The elongated hole or slot is placed at right angles to the sash so that the stop can readily be moved in or out as the sash swells or shrinks. They may be obtained in all finishes with screws to match. They cost from 12 to 25 cents a dozen in ordinary finishes.
