line with the section above.
oblique line and the upper section is suspcnded from above, the weight of each lower section will draw it into and maintain it in Fui'llierniore, the complementary keys4 and keyways pre- Y vent lateral relative displacement of one section with respect to another. Again.
-. since one straight, sliding knuckleA is the exact and full complement of the other knuckle of the interlocking pair of knuckles, there is no space between sections to cause loss of weight or to permit one section to swing ont of line with respect to the next section.
The forms of interlocking knuckles shown in Figs. 2. 3, 4 and G, not only prevent lateral relative displacement of sections, but
,y they prevent swinging of one section with respect to another, even when the weight is not suspended -in a well. The form of knuckle shown in Fig. 5, however, while preventing lateral relative displacement, locs permit swinging of one section with l res ect to another since the hook is 'curved laterallyY on the 'arc 0f a circle, but such swinging cannot take place when the weight `is suspended in the usual well. Each weightv is provided in its` hook c with a hole 1' to re- `ceivc the end of the sash cord Z- which may be knotted underneath the hook, as at l". The hole i is toi-med in the line of tne axis` of the section and the section will, therefore, hang perfectly straight from the cord. As each section has with the next section a bearing in a line which is symmetrical wit-h respect to the vertical axis. each section hangs ina straight line with the one above it.
It will be obvious that if the sectional sashweiglit, when suspended from above and descending, should be allowed to strikek on Y its lower end, the straight, sliding hooks would' p ermit disengagement of the sections if the sections were not held from relative displacement by the walls of the well. Itmay be thought desirable, in cases where the walls of wells cannot be depended upon to' prevent relative displacement of the sections, to guard' against such displacement.
Accordingly, the angle of the hook b, c, may
be recessed or cliamfered oil', as at l, and the other end of the same face or side of the weight may be provided with a low, coniplementary rib m. The height of the rib m does not exceed the extent of play between A the sections, so that it does not. prevent the engagement of one section with another, but
it will he obvious that it the lower end of a sectional weight is about to strike while the weight is descending, the play between successive sections will be taken up and the rib m, although low, will enter the correspoinl-` ing knuckles as described, especially with a key or rib or ridge transverse to the face of the knuckle, the desirable features of a sectional sashweight can be combined and facility in connection, maintenance of alineinentand nonliability to accidental displacement be secured at a minimum cost of manufacture.
venience of the manu-facturerer or the desires of the user and that the invention is not. s
restricted to the precise forms shown and described herein.
I claim as my invention:
1. A sectional sashweight having at each end a straight,slanting knuckle with parallel surfaces, the knuckle at one end being the complementJ of the knuckle at the other end, such sectional sasliweiglit being adapted to beengaged with and disengaged from the lnext by bodily oblique movement with its axis parallel with that of the next.
2. A sectional sash weight having` at each end a straight, slanting interlocking knuckle with parallel surfaces, theV knuckle at one end having a transversekey and the knuckle at the other end having a complementary.
keyway, such sectional sashweight being adapted to be engaged with and disengaged from the next by bodily oblique movement with its axis parallel with that of the next.
3. Sectional sashweights having straight, slanting interlocking knuckles with a low rib across the end of one section to engage the adjacent end of the next section to prevent disengagement of the knuckles when the lower section is held from movement downward.
This specification signed and witnessed this 15th day of December A. D. 1909.
