the balancing weights for window sashes.

The old form of sash weight which is now in general use and which consists of an integral solid cast body havinga perforated ear at one end presents several disadvantages in its use. Inasmuch as window sashes vary greatly in weight, it is often a diflicult matter to procure a sash weight of precisely the weight required to serve itspurpose inbalancing the particular sash to be fitted and under these conditions it is customary to select a weight heavier than the one required and then break otf'a piece of the same so as to suitably reduce its weight. This, however, involves the expenditure of time and labor and there is always the liability of breaking ofi'too large a portion of the weight. Furthermore, dealers in supplies of this kind are required to carry in stock various sizes of the welghts which is another undesirable feature. In the use of the ordinary weight, furthermore, the sash cord end is threaded through the opening in the ear of the Weight and then knotted but as a result of this methodof attachment, the weight is not perpendicularly suspended as regards its long axis but is suspended in a more or less tilted position so that it is liable to run unevenly in the window frame and become hung and, furthermore,the sash cord is liable to become untied. In either event it is necessary to open the window frame to remedy the trouble and this also involves the expenditure of time and labor. In, consideration of the disadvantages presented by the ordinary form of sash weight as briefly pointed out above,the present invention has as one of its primary objects to provide a weight so constructed that its mass may be readily increased or diminished in a simple manner and without destroying or damaging any portion of the weight.

Another object of the invention is to provide a sash weight so constructed that the same may be manufactured in a single standard size or at most in a minimum number of different sizes thus reducing the number and variety of the articles which a dealer is required to keep in stock, the weight being capable of being readily filled to a greater or less extent with a suitable we ghtlng material until it possesses the re qu red mass depending, of course, upon the weight of the sash to be balanced.

A further object of the invention is to so construct the weight that the sash cord may be readily and conveniently connected therewith in a manner to perpendicularly suspend the weight so that the same will travel freely in the stiles of the window frame. The invention also has as one of its obects to so construct the attaching member of the weight that, with equal facility, a sash cord, chain,lor tape may be connected therewith. V

A further object of the invention is to so construct the connectingmember for the sash weight that where the weight is to be employed in connection with a sash cord,

the knot tied in the end of the cord will be same being illustrated as suspended from a sash cord;

Fig. 2 is a vertical longitudinal sectional view through the weight shown in Fig. 1;

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2 and looking in the direction of the arrows;

Fig. 4 is a view similar to Fig. 2 but illustrating the manner in which a sash chain may be connected with the weight;

Fig. 5 is a similar view illustrating the manner in which a sash tape may be connected with the weight.

The weight embodying the present invention is indicated in general by the numeral 1 and the same comprises a hollow cylindrical body 2 which is of metal or other suitable material and which is interiorly threaded at its upper and lower ends as ind cated respectively by the numerals 3 and 4. The lower end of the body is closed by means of a plug 5 threaded into the said end and provided with a polygonal boss 6 for the application of a wrench or other tool for the purpose of fitting into place or removing the said plug.

The upper end of the body 2 is closed by means of a combined plug and attaching member which is indicated by thenumeral 7 and the same comprises a plug body which is threaded intothe upper end of the said body 2 and is formed exteriorly upon its top with a boss 8 which is preferably polygonal for the application of awrench or other tool as in thecase oi the plug 5. This boss and the said top oi the plug 7 are formed with an opening 9 preferably cylindrical and ex tending in line with the axis of the said plug 7 and body 2. The boss 8 is formed also in diai'netrically opposite sides with perform tions 10 which are in alinenient and coin- Inunieate with the opening 9.

i In the use oil the weight the same is tilled or partly filled with any suitable weighting material 1]. such for example as metal disks, punch slugs, metal turnings or; cuttings, dry sand, iron ore, or in fact any material a quantity of which may be contained within the body and which will .in conjunction with the weight of the body provide suliicient mass to properly balance the sash to be hun In il igs. l and oi? the drawings the weight is employed in connection with a sash cord of the ordinary type which is indicated by the numeral '12 and the lower cnd of this cord is fitted downwardly through the opening 5), and is tied in a knot 13; the cord being then drawn through the openin so that the knot will seat and be housed within the concavity of the plug i, the plu being hollow as indicated by the numeral l r, for this pur pose. The cord having been connected with the plug 7 in the manner stated and the body oi? the weight having been. supplied .with a suitable mass of the lilling material or metal disks ll, the plug is threaded into the uppcrwendoi the body and the weight is then ready to perform its functions. Of course, it the weight is found to be too inassive, either the plug 7 or the plug 5 may be removed and a greater or less number of disks or quantity of the filling material may weight is found to be too light after its ends havebcen closed, the plug in either end may be removed and more of the disks or filling material may be introduced.

In the form of the invention shown in l ig. 3 of the drawings, the weight is employed in connection with a sash chain which isindicated by the numeral 15, the lowermost or terminal link of this chain being fitted within the opening 9', and a pin 16 being driven through the periliirations 10 and through the eye of the link so as to connect the link. with the plug 7.

In Fig. (l of the drawings the ninneral 17 indicates a metal tape such as is sometimes eniployed in hanging sashes and the end of this tape is 'lorniedwith a perforation l8 and is fitted into the opening 9 after which a pin 19 corresponding to the. pin 16, is

driven through the perforations 10 aiul through the opening 18 in the sl tape so as to connect the tape with the weight.

The interior walls of the opening 9 at the upper and lower ends thereol v are preferably flared laterally as indicated at 9 so as not to present any sharp edges which would tend to cut or brade the sash rope.

H a vin thus described theinvention, what l I n n is clanned new is: a l y A sash weight comprising a hollow body threaded at one end, and a plug re novably fitted to the said end of the body and closing the sa ine and having its up per side provided with an upstanding rectangular bos the said plug being provided in its under side.

with a eoncmity and the plug being formed with an opening extending axially through its top and axially through the boss, and the said boss being formed with a transverse opening intersecting and connnunieating with the first mentioned opening and opening through opposite sides of the said be 1.
