OF CINCINNATI, OHIO, ASSIGNOIt TO THE LUNKEN STEEL WINDOW (30., OF CINCINNATI, OIIIO.

SASH-WEIGHT.

Specification of Letters Patent.

Application filed October 13, 1908.

Patented Feb. 23, 1909.

Serial No. 457,545.

To all whom it may concern:

Be it known that I, CHARLES M. CoNKLIN, a citizen of the United States, residing at Cincinnati, Ohio, have invented certain new and useful Improvements in Sash-Weights,

of which the fo owing is a specification.

My invention relates to improvements in sash-weights and more particularly to sectional sash-weights in which two or more sections-may be secured together to make up the requisite weight necessary to counterbalance the window sash.

One of the objects of the invention is to provide a sectional sash-weight in which the sections may be coupled tpgether while both members are in approximately upright posi- ,tion and thus obviate the necessity of having to turn one section at right angles to the other when making the connection.

Another object of the invention is to provide in a sectional sash weight a joint secure against accidental dis lacement when in use and yet one capable 0 being easily attached and detached when necessary.

The novel features and details of construction, hereinafter described and particularlyclaimed, are embodied in the. accompanying drawings, in which,

Figure 1 is a side elevation of two sections of my improved weight, with the lower part "of the bottom member in section, Fig. 2 is a front view of the members shown in Fig. 1. Fig. 3 is an end view showing the male couplin member of a section, and, Fig. 4 shows t e reverse end or female.

In these drawings the numeral 1 designates a representative sash-weight section having the ordinary body portion, its upper end being reduced to form the male coupling member 2. This male member 2 com rises a central rib 3v having thereon two suitable bosses or lugs 4 which are adapted to fit into corresponding recesses formed in the adjoining section. At the lower end of the section I provide a suitable bifurcated or female memberl5, which is formed with an enlar ed recess 6 ,to accommodate the lugs 4, an a reduced pa e 7 formed by the lugs 8 on each side omich the lugs 4 rest. The lugs -8 are rovided with shoulders 8 behind which t 1e corners 4 of the lugs 4 rest as indicated at thecenter of Figs. 1 and 2, it being understood that the lower member is connected to the upper by a relative movement from right to left. The extended end 2 of the rib or web 2 bearing against the shoulder 6 limits the movement. After the parts are in the position shown in Figs. 1 and 2 they are locked in position and against accidental displacement by the respective shoulders and disengagement can only be eflected by lifting the lower section.

By the above described construction I am enabled to provide a simple-and efiicient sectional sash-weight at a minimum cost, and one which is readily coupled and uncoupled while remaining in substantially upright position.

It will be obvious from the above description and by reference to the drawings that I provide a sash weight com osed of universal section units, which may e added to or subtracted from according to requirements.

The sash-cords may be conveniently passed around the lugs 4 and tied or otherwise secured. The lower walls or faces of the lugs 4 and the upper faces of the lugs 8 to the left of the shoulder 8 are preferably inclined with relation to each other so that the walls diverge from the center. This makes the point of contact or support directly in the center and causes the sections to hang plumb, even though rough places be left by the casting. All 0 posing walls of the recesses are preferably ormed diverging for convenience in casting.

What I claim is 1. As an article of manufacture, a sash weight comprising a plurality of sections, each section having a web at one end provided with side projections, and a laterally opening recess at the other, the side walls of said recess having inwardly projecting lugs, and oppositely projecting shoulders on said lugs, and the upper wall of the recess, substantially as described.

2. As an article of manufacture, a sash Q magma weight complrising a plurality of sections, 1 having also oppositely extending locking each section aving a web at one end with a shou pair of laterally projecting lugs and a locking portion projecting above said lugs at one side 5 thereof, the other end of said section having a bifurcated portion to receive the In s of the next section; the walls of said b' rcated portion having inwardly extending ribs, and

rs, substantially as describe In testimony whereof, I afiix my signature in presence of two witnesses.
