JOHN D. ANSLEY, OF EVERETT, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO ALLSTON FOUNDRY COMPANY, A CORPORATION OF MAINE.

SASH-WEIGHT.

SPECIFICATION forming part of Letters Patent No. 705,992, dated July 29, 1902.

Application filed June 19, 1901. Serial No. 65,168. (No model.)

To all whom it may concern: I

Be it known that I, JOHN D. ANSLEY, a ci-tizen of the United States, residing at Everett, county of Middlesex, State of Massachusetts, have invented certain newand useful Improvements in Sash-Weights; 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 ap pertains to make and use the same.

The invention relates to sash-weights, and has for its general object to provide the end of the weight to which the suspending cord or chain is attached with a recess to receive and completely house, conceal, and protect the knot or ring on the lower end of the cord or chain; and the particular object of the in vention is to make the recess self-centering of the knot or ring on the suspending device, also to make the upper portion of the recess of such size and shape as to freely receive and eifectually hold the knot or ring, and to provide the" recess with 'openings into its lower portion on either or both sides of the weight to facilitate the fastening of the knot or ring on the end of the cord or chain.

Theinvention is the same as that of my prior application,"N o. 707,569, filed March 3, 1899, of which this is a refiling. It is illustrated in the accompanying drawings, wherein Figure 1 is a side View of one of my weights, showing its external form and having therecess indicated in dotted lines. Fig. 2 is a similar view at right angles to that of Fig. 1, showing more clearly how the side openings are arranged and located with respect to the recess and the end of the weight. Fig. 3 is a longitudinal central section through the weight and recess, the weight being suspended by a cord having a knot in its end. Fig. 4 is a cross-section of the weight through the upper part of the recess. Fig. 5 is a sectional View similar to Fig. 3, but the weight being suspended by a chain having a ring at its lower end.

Referring to the views, cdenotes the weight as a whole. It is preferably cylindrical in form and may beof any appropriate length and diameter for the particular use to which it is to be put.

foration 01, through which passes the lower portion of the cord or chain by means of which the weight is suspended. This perforation opens centrally into the top of a recess 6, that is formed longitudinally of the weight in the .center of its upper end, this recess being provided to receive and hold the knot or ring on the end of the suspending cord or chain. The arrangement and conformation of this recess is the important feature of the invention, and the utility of its construction will be understood when it is considered that the knot or ring must be completely housed, concealed, and protected within the Weight,and, moreover, that it must be accurately centered in line with the perforation through which the cord or chain passes in order to insure the hanging of the weight plumb in the well. The recess must therefore be of a size snfti cient to receive and hold the knot or ring with out jamming against its inner side walls. It must also be dome like or provided with arched Walls gradually converging from the largest diameter of the recess to the central perforation e, the value of this construction being that it makes the recess self-centering of the knot or ring. Preferably the recess is circular in cross-section, as best shown in Fig. 4, and' it may be of any desired length in the longitudinal direction of the weight. As will best be seen in Fig. 3, the recess is laterally flared or enlarged upwardly from its lower end and is provided with an opening or openthrough one or the other of the side openings. The knot is then formed or the ring is attached, as the case may be, after which no further attention is required and the weight is ready for .use.

As will be seen in all the figures, the side opening only extends up about midway the height of the recess and is narrower at its upper end than at its lower end. The widest part of the opening is also considerably narrower than the widest part of the recess, and as the recess widens the opening, which is the entrance to it, becomes narrower, and, vice versa, the opening widens as the recess narrows.

As best seen in Figs. 3 and 5, the widest part of the recess is about midway of its length and just above the top of the side openings, and from this widest point the inner walls or crown of the recess is dome-like in I shape and converges toward the center, so as to guide and direct the knot into the line of the center of weight of the device.

In Fig. 3 the suspending-cord is an ordinary manila, hemp,or other rope and the knot is tied in it by hand in the ordinary man ner. In Fig. 5, however, the more general arrangement, especially for heavy windows, is shown-.-viz., a chain and ring.

The self-centering function of the side walls of the recess will beapparent from these views, particularly the fifth, where the ring finds a seat for itself in the top of the recess at the entrance of the perforation, and the ample space provided by the recess for both the knot and the link without cramping will be noticed.

So far as the recess is concerned, considered apart from the opening f, the particular advantages of my weight are that the knot or ring is completely housed in the recess and is also concealed and protected. It is also free to move around in the recess and adjust itself to the inner walls thereof, the circular form of the recess shown in Fig. 4 permitting this accommodation.

. Considered in connection with the openings I upper part and no amount of rebound of the weight can dislodge it.

Such being the construction of my improved weight, it will be seen that it always hangs plumb from the center of the suspending cord or weight and that it is, moreover, free to return to plumb position after any accidental displacement, the freedom of movement of the knot or ring in the recess, which is due to the fact that the weight is all borne by the top of the knot or ring and not by jamming against the sides, permitting the-weight to turn on the cord or chain in case of twisting of the latter.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. A sash-weight, having a central perforation in one end through which the suspending cord or chain passes, a recess in the top 'of which the nut or ring on the end of the cord or chain seats itself, and into the center of whichsaid perforation opens, said recess extending centrally lengthwise the weight, and having its upper portion laterally flared or enlarged and provided with a dome-like top with self-centering walls, and an opening leading into the lower part of the recess, said opening being narrower than the widest part of said recess.

2. A sash-weight, having a central perforation in one end through which the suspending cord or chain passes, a recess in the top of which the knot or ring on the end of the cord or chain seats itself, and into the center of which said perforation opens, said recess extending centrally lengthwise the weight, and having its upper portion laterally flared or enlarged and provided with a dome-like upper end having self-centering walls converging toward the central perforation, and openings on opposite sides of the weightleading into the lower part of the recess, said recess having its greatest diameter above the top of the openings, and the latter being narrower than the widest part of the recess.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN D. ANSLEY.
