rasante Specification of Letters Patent.
Patented J uly12, 1921i.
Application filed March 19, 1921. Serial No. 453,829.
To all w hom t may 00a-cera Be it known that I, Eton R. LEONARD, a citizenr of the United States, residing at Mountain Lakes, Morris county, New Jersey, have invented certain new and useful lmprovements in Sash-l/Veights, of which the following is a specification.
My invention relates to weights for counterbalancing window sashes, and the like, wherein a plurality of units or sections are attached to each other in order to obtain the desired aggregate weight. And my improvements are directed to the means whereby the weight sections may be attached to each other, so as to be readily connectedand disconnected; and also in the other particulars hereinafter pointed out.
ln the drawings, Figure l is a side View of two of my improved weight sections; Fig. 2 is a similar view, looking to the left on Fig. l, the upper end being partly in section; Fig. 3 is an end view, looking up on Fig. 2; Fig. 4 is a side view showing the two sections in position to be joined or disconnected; and Fig. 5 is a side view of three weight sections, showing the method of inserting them in a window frame; and Figs. 6, 7, 8 and 9 show modications on a reduced scale.
The same parts are designated by the same reference numerals in all the figures.
The weight sections are preferably made of cast iron, or similar material, each being cast as an integral and complete unit, and embodying terminal elements which are adapted to engage detachably with a duplicate section.
Thus, as shown in the drawings, the body 1 of each section is approximately square in cross section, but, is, preferably, slightly curved outward at 2, 2, so that these faces of the weight may not drag flatly against the inside of the window casing, if the weight should happen to touch the casing. However, the sections may have a round, oval or otherwise curved cross section; if desired.
Both ends of each section 1 are cut away to about half t-he thickness of the section, but upon opposite sides of it. And the reduced portion of one end is provided with an integral pivot pin 3, while the reduced portion of the other end is provided with a pivot hole Ll, which passes through the end, and is provided with a constricted portion and with an enlarged socket opening 6 in its outer face. Each end of the section is provided with an undercut groove 7, formed between the body of the section and a flange 8, the central portion of which flange is extended forward at 9, so as to give the end of the flange the form of an obtuse angle. The apex of the groove 7 behind the flange is, however, preferably rounded over, so as not to present an angular elevation.
Each of the extreme ends of the section is provided on its outer side with a curved rabbet 10, the outer shoulder 11 of which may be struck upon a true curve from the center of the pivot 3, or the hole 4, as the case may be, while the adjacent end of the `section l2 is formed upon a curve of the same radius, but from a center nearer the end.
it will be seen then, that when two sections are placed at an angle to each other, as shown in Fig. l, the pivot on one may be slid into the socket in the other; after which, if the sect-ions are straightened out, the end 12 of one section will vswing into the groove 7 of the other section, and the sections will be thereby connected together so that they may be swung in relation to each other, but cannot be separated unless they are carried to such an angle that their flanges 8 are allowed to travel out of the adjacent grooves 7.
The flexibility thus provided for in the string of weights is sufficient to permit it to be slid through the usual opening, as 13, in a window casing 14, into the weight box 15, without the sections becoming separated. And, once within the weight box, and sus pended to the chain 16, the sections will be securely attached to each other and not become separated in ordinary use.
The purpose in forming the hole land socket G in the way described is to afford a convenient means for attaching the chain to any weight section so that the weights will hang true on the chain, and the attaching means will not project beyond the side lines ofthe weight so as to catch or rub against the sides of the weight box.
ln the drawings l have shown the chain 16 as attached to a looped wire 17, the ends 18, 1S of which are passed through the constricted portion 5 of the hole and spread out in the socket 6, so that they cannot be readily withdrawn therefrom. rlhis is illustrative of a suitable method of attachment. But it is obvious that other equivalent methods of attachment might be employed, and that details of construction of the weight sections may be varied, as by the use of mechanical equivalents, Without departing from the spirit and scope of my invention as claimed.
In Figs. 6 and 7 I have shown, on a reduced scale, a side view and an edge View of a modification of the locking means, anges 19, 19 being made to coperate With grooves 20, 2O in the adjacent ends of the sections; and in Figs. 8 and 9 I have shown another modiication wherein inwardly beveled shoulders 2l, 2l are made to coperate With undercut grooves 22, 22 in :the .adjacent ends or" the' sections. These modifications are shown to illustrate possible variations of construction.
Having thus described my invention what I claim and desire to secure by Iietters Iatent of the United States is l. In sectional sash-Weights, the combination of a plurality of duplicate, integral sections each provided at one end with a reduced and extended portion provided With a lug connecting element and With a lateral, locking fiange projecting from the unreduced portion, and at its other end with a reducedand extended portion provided With a socket connecting element and With a lateral, locking flange projectingfrom the unreduced portion.
2. In sectional sash-Weights, the combination of a plurality of duplicate7 integral sections eac-h provided at one end With a reduced and extended portionprovided with a lug connecting element, a locking iiange projecting from the unreduced portion, and a transverse groove behind said locking iiange, and at its other end with a` reduced and eX- tended portion provided with a socket con necting element, a locking flange projecting from the unreduced portion, and a transverse groove behind said locking flange.
3. In sectional sash-Weights, the combinationof a plurality of duplicate, integral sections each provided "at one end with a lug connecting element, a transverse, arcuate vOfroove and With lateral lockinv flanges D 7 7 b C 7 tion of a pluralityy of duplicate, integral sections each provided at one end with a. lug connecting element and with lateral, locking flanges having angularly projectedA terminals, and at its other end with a socket connecting element and with lateral, locking flanges having Yangularly lprojected terminals. *l
