SASH WEIGHT.

Application filed July 19, 1921. Serial No.

To all whom it may concern Be it known that I, WILLIAM S. SANBORN, a citizen of the United States, and resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Sash Weights, of which the following is a specification.

My invention relates to sash-weights and more particularly to that type which are commonly referred to as sectional sash weights and generally comprise weight members adapted for interlocking with one another to provide the required weight. Because of the characteristics of sash-weights in general, it is desirable to construct the same as cheaply as possible and yet in a manner to provide the desired weight and eflicie-ncy of operation. With this in mind, the manufacturers of sash-weights have generally utilized the cheapest materials obtainable, such as scrap-iron, the most common practice being to cast said sash-weights of such scrap-iron. Such saslrweights are, however, extremely brittle, and in the case of sectional sash-weights made therefrom, result in a weight which, while it is eminently satisfactory in all other respects, is weak atits oppositeends because of the connecting devices which must be located thereat for connecting individual weights in series thereat. At the points mentioned the sectional sash-weights, during shipment and in handling, are more or less easily broken, and through the resultant destruction of the connecting devices, are rendered useless for the intended purpose, and consequently represent aloss to the manufacturer, dealer or purchaser. The particular purpose of the present invention is to overcome these objections in a novel and simple manner by providing a sash-weight which includes, as an inherent property, all of the rigidity and mass necessary to provide the required weight and in which the connecting means are incorporated in a manner to overcome any weakness and to prevent breaka e thereat. My invention will be fully described hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings, which. illustrate an example of my invention without defining its limits, and in which Figure 1 is an elevation of the sash-weight showing several sections joined Specification of Letters Fatent. Patrg-ntgd Aug. 1, 1922.

together; Fig. 2 is an elevation of a single weight partly in section; Fig. 3 is an end view thereof, and Fig. 4 is a cross-section on the line l l of Fig. 2.

As shown, the sash-weight comprises a body 5 which may be of any suitable crosssectional shape and axial length and is preferably cast of scrap-iron; at its one end the body 5 is continued in the form of integral spaced extensions 6 which define a space 7 bridged or spanned at an intermediate point by a cross-bar 8 which also comprises an integral part of the weight, said extensions 6 and cross-bar 8 being formed by casting in a suitable mold. At its opposite end the weight is provided with a connecting device whereby the sash-weights are coupled. to gether in sections and. which, generally speaking, is in the form of hook 9 suitably constructed for insertioninto the space and co-operating with the cross-bar 8 to suspend one weight from another. In the present invention the hook 9 is constructed of wrought or malleable iron or of any other metal or material which is not brittle and possesses an inherent rigidity corresponding, at least, to that of the body 5. In the preferred form the hook 9 is of rectangular flat form and has a major width approximately equal to the cross-sectional dimension of the body 5 in at least one direction;

as shown in the illustrated example, the

hook 9 extends into the body 5 and is provided with an aperture 10 through which the cast-iron or other material of which the body 5 is constructed extends in the form of an integral bar 11. This result is secured by casting the body 5 about the hook 9, it being understood that the aperture 10 and bar 11 are intended to be representative of equivalent means whereby a separation of the hook 9 from the body 5 under pulling strains is resisted. The hook 9 extends into the body 5 only to the extent necessary to secure a rigid connection, it being understood that the combination of said hook and body is effected, as previously indicated, by casting the latter about the former, a most intimate and reliable union between the hook and body bein secured in this way and the operation of connecting the same being reduced to the simplest form and made coincident with the construction of the body.

The hook 9, because of its physical. characteristics and because of its inherent flexibility, not itself easily fractured or broken and at the same time, when coupled to another weight section, and because of these properties, absorbs strains and shocks which otherwise would be communicated to the eX- I tensions 6 and tend to break the same. The recognized weaknesses of sash-weights of the type in question are thus overcome in an efficient and simple manner and the possibility of breakage is reduced to a minimum.

In aractice the sash-wei hts are utilized in the recognized manner by attaching the sash-cord to the cross-bar 8 of the terminal section and coupling such additional sections to said terminal section and to each other as may be necessary to provide the desired counterbalance of the particular windowsash in question.

' l/Vith the present invention, in which the desired mass 01? weight is 01' no consequence,

as the connecting operation may be repeated as often and as carelessly as possible without danger oil breakage oi said connecting devices.

The present invention practically eliminates the waste resulting from breakage of: the sash-weight sections and reduces the loss "oftime incident to replacement because'of breakage on the job to a minimum point.

shown and described'may be made within the scope or the claims without departing from the spirit of my invention.

I claim:

l. A sectional sash-Weight comprising a body of castiron provided at one end with integral. coupling means, a relativelyfiat coupling hook ofinalleable iron located at the otherend of said body and extending into the same to an extent which corresponds to a fractional part of the axial length of said body, said malleable iron coupling hook havinga major width corresponding to the cross-sectional width of the body in at least one-direction and means within said body extending transversely to said major width of said malleable iron hook whereby separation of the latter from said body is resisted.

2. A sectional sash-weight comprising'a body of cast-iron provided at one end with an integral coupling means, a coupling hook oi malleable iron located at the other end of said body and extending into the same to an extent which corresponds to a fractional part of the axial length of said body, said hook having a major width corresponding to the cross-sectional width of said body in at least one direction and being provided with an aperture extending through said hook transversely to said major width atan intermediate point; and a bar comprising an integral part of said body and extending through and completely filling the aperture of said hook. y

In testimony whereof I have hereunto set my hand.

WILLIAM s. SANBORN.
