SASH-LIFT.

SPECIFICATION forming part of Letters Patent No. 404,666, dated June 4, 1889.

Application filed February 1,1889. Serial No. 298,355. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM ALEX WIL- LIAMSON, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in WVire Sash Lifts or Pulls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in sash lifts or pulls; and the object of the invention is to provide a simple, cheap, and durable sash-lift designed to be attached to a sash-frame by means of screws, and in the accompanying sheet of drawings is illustrated my invention.

Heretofore sash-lifts have been cast, or were made of malleable iron, which necessitated the tumbling of the same in order to clean the surfaces of the lifts before applying a coat of japan to the surface; also, the screwholes had to becountersunk in order to receive the heads of the screws, which forms quite a material proportion of the total cost.

To overcome the above, as well as other objections, is the purpose of my invention.

It consists, essentially, of a lift or pull formed from a continuous piece of wire bent in the middle to form an eye adapted to receive a screw or pin and twisted and bent into shape, the free ends of the wire being bent into hooks to form a handle or pull for the fingers, by means of which the sash may be raised.

The invention will be more fully understood from the description given below, reference being had to the accompanying sheet of drawings, in which similar letters of reference are used to indicate corresponding parts in each of the several views.

In said views, Figure 1 is a front elevation of one form of my improved lift or pull attached to a partof a sash-frame, and Fig. 2 is a side elevation of my improved lift.

The improvement disclosed in the abovedescribed views is made from a.eontinuous piece of wire of any desirable cross-section, and is bent in the middle thereof into an eye (L to receive a screw or pin b for securing the pull or lift to the frame of the sash, and the free ends of the wire are bent, as shown, and formed at the ends thereof into hooks or loops at and a, to form the pull portion for the insertion of the fingers. As illustrated more especially in Fig. 1, the wire, after being bent at the middle and formed into the eye a is twisted, as at a and the free ends of the wire are bent into the hook portions a and a, which extend downwardly and are parallel with each other, or approximately so.

It will be seen that by. the construction shown and described in the above an efficient and inexpensive article is produced, which can be formed of a wire of uniform thickness and of any cross-section, thereby making a very neat and ornamental lift or pull for window-sashes, (to.

This form of sash lift or pull is of great advantage, as additional strength and durability is an essential feature, which has been attained in the device herein described and shown by twisting the wire and thereby preventing the possibility of the pulling open of the eye for securing the lift to the frame of the window-sash. Furthermore, this form of wire sash lift or pull is a very serviceable one, as all danger of the wires or legs of the lift from spreading apart, as is the case in wire sash-lifts as heretofore made, is thereby avoided.

The free ends or hook portions a and a, instead of being round in cross-section, as illustrated in the drawings, may be flattened to conform with the shape of the fingers, in order that the sash may be raised with ease, as will be understood.

The sash lifts or pulls as described in the foregoing may be applied to doors or drawers as well as to window-sashes, and I therefore do not wish to limit myself to the application of my improved lifts or sashes only.

I am aware that it is not entirely new to make sash-hooks from a continuous piece of wire, hooks having been made in which the wire is quadrupled, thereby necessitating a considerable length of wire. In my improved pulls to windowhook, which is simple in construction. and still very strong, I am enabled to reduce the cost of manufacture of the same considerably, requiring but a short piece of Wire, and I am also enabled to make the hooks described in the above by means of machinery which is less complicated in construction than the machines which have been employed to make the hooks as heretofore used.

Having thus described my invention, What I claim is A sash lift or pull made from a continuous piece of wire doubled and bent in the middle to form an eye for the reception of a screw or pin, and twisted, as at a and the free ends thereof bent into hooks to form a pull portion, substantially as and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereunto set myhand this 20 30th day of January, 1880.

WILLIAM ALEX WILLIAMSON.
