' sAsH WEIGHT Filed March l2, V1928 Patented June 24, 1930 STTES CLAUDE E. BOI/VERS OF LOS ANGELES, CALIFORNIA SASIEI WEIGHT Application filed March 12,1928. Serial No. 260,860.
This invention relates to sash weights, and more particularly to that type which houses a sheave for the sash cord.
The primary object of the invention is to' provide a satisfactory sash weight construction which may be simply and easily built at a comparatively low cost, and which in addition tobeing durable may also be weighted as desired at the time of assembly.
Briefly stated the invention resides in a casing to which and within which there is secured a sheave housing containinga sheave for the sash cord, the casing containing a quantity of material to provide the desired weight. Preferably the casing is filled with alternate quantities of a filler or binder and of small metal bodies, the amounts of each being regulated as required to provide the necessary weight. Preferably the sheave and its housing are formed so that the sheave is journaled on offset portions of the housing, and extensions of the housing are folded into seams which bind together the sections making` up the casing.
The invention resides also in the method of assembling the structure and settling the filling and weighting material into place, as more particularly set forth hereinafter. The invention resides further in such other novel features and constructions as may be herein disclosed.
In'the accompanying drawings wherein certain embodiments of the invention are disclosed by way of illustration- Fig. 1 is -a perspective view of a completed sash weight.
Fig. 2 is in part a face elevation. and 1n part a vertical section showing internal features of construction.
Fig. 3 is a vertical section taken on the line 3 3 of F ig. 2.
Fig. 4 is a cross section taken on line 4.-4 of Fig. 2.
Fig. 5 is chiefly a vertical section showing a. jigging apparatus as employed to settle the material used to fill and weight the device.
rlhe sash weight casing 10 is preferably formed in two sectionsiwhose vertical edges are folded or crimped upon each other to form seams 12. Mounted in one end of the casing is a sheave housing preferably formed in two sections 25 and 26, each provided with semi-circular flanges which are secured together by rivets 16. The upper ends of the flange of housing section 26 are extended to form webs 14 that are folded into the vertical seams 12 of the casing to hold the housing in rigid relation thereto, see Fig. 4. Similarly the sheave 18 is feo formed of two circular members flared at their peripheries tol form the annular cordreceiving groove 20, the housing 15 being correspondingly depressed at 22 to form circular bearings which engage with the flared1 c5 portions of the sheave and upon which the sheave is thus journaled, the relation of the sheave parts being maintained by an eyelet or rivet 24 preferably integral with one of these parts. 10
In assembling the weight, the sheave having been lirst secured in its housing, the sections of the casing 10 are crimped to gether with the edges of the extensions or webs 14 of the sheave housing therebetween7 75 thus forming the side seams 12 and binding the housing 15 in the upper part of the casing. The casing is then inverted and set on a jig so that pins 30 carried by the bed 32 of the jig are received in the spaces v so formed between the sheave groove and the" side walls of the housing, while the ends of the casing are received in a tapered groove 34 so proportioned as to bind upon said ends and to assist retaining the casing on the jig. The casing then receives charges of a filling" or binder material such as tar or asphalt alternated with quantities of heavier weighting material such as small scrap metal bodies or lead shot. As indicated inFig. 3, a quantity of tar filler 35 is first placed, their a quantity of scrap metal 36, then more tar 38, and further quantities of tar 38 and metal 3G as shown. Meanwhile the jig bed 32 is vibrated as by means of an irregular 95 cam or other jigging device 40 which upon rotation imparts a rapid vertical reciprocation to settle the filling materials in the casing and about the housing 15. A stationary support 42,- receiving guiding fingers 44 on 100 the .bed 32, serves to carry the jigging mechanism.
lVhen the casing has been filled and the materials settled, a bottom piece 45 is placed and the ends of the casing Walls folded over as at 4G. The lilled casing is then removed from the jig, and a top plate il-8 having cord receiving holes 50 is placed en top of the sheave housing l5, the upper ends of the side walls then being turned over at 5l, thus completing the assembly. If desired the bottom Ll5 could be set over the pins 30 before the casing is placed for filling.
To use the device it is merely necessary to pass the cord through one oi the holes 50 and force it through the guides which cause it to emerge from the other hole. Since the amount of Weighting materials may be varied as desired, any suitable Weight may be easily obtained with a single size o'f casing.
A sash Weight comprising a sheet metal casing, a sheave housing 'formed oit sheet metal mounted Within the easing adjacent one end thereof, a sheave Within the housing having an annular groove to receive a sashcord7 a Weighting and a plastic binding material therefor packed in said casing, and end plates for closing the ends of said casing7 the end plate adjacent the sheave housing having openings for the passage therethrough ol" the sash cord.
In testimony whereof I allix my signature.
