Description
PAT-ENTED AUG. zo, 1907.
CHARLES E. POPE, OF PITTSBURG, PENNSYLVANIA.
BALANCE-WEIGHT.
Specification of Letters Patent.
Patented Aug'. 20, 1907.
Application filed June 11l 1906. Serial No. 321,134.
To all whom 'it may concern:
Be it known that l, CHARLES E. Porn, a citizen of the United States, and a resident of Pittsburg, county of Allegheny, State of Pennsylvania, have' invented Certain new and useful Improvements in Balance- Weights, of which the following is a specification.
My invention relates to tubular balance weights such as are commonly used to counterpoise window sashes, l
and for Similar purposes. Its object ,is to produce a weight which shall be of substantially the same specific gravity as the ordinary cast iron weight, but of smoother exterior surface, and less frangible, as well as more economical in manufacture.
In the drawings, Figure 1 is a View partly in elevation and partly in vertical section of an unfilled balance Weight embodying my invention. Fig. 2 is a similar view of the weight taken at a right angle with the View shown in Fig. 1 and showing the filling. Fig. 3 is a partial vertical section showing a modified form of my device. Fig. 4 is an elevation of a head adapted to be used in the modied form of the device shown in Fig. 3.
To make the sash weight shown in Figs. 1 and 2 of the drawings, I take a piece of Wrought iron or steel tubing 10 of the proper length and diameter for the required weight and form internal threads 11, 12 at its upper and lower ends respectively. As a closure for one end I make a head 13, which may be of cast or wrought metal, exteriorly threaded at 14 to engage with the thread 11. The plug or head 13 is provided with an axially disposed flattened vertical lug 15 pierced at 16 to form an aperture for the reception of the supporting cord or chain. The lower end of the body 10 is closed by a plug 17 eX- teriorly threaded at 18 and preferably provided with an axial polygonal recess 19 for the reception of a tool by which it may be screwed into position. After one of the plugs 13 or 17 has been screwed into position the body or shell of the Weight is filled with a mass 20 of suitable heavy filler, which may be iron ore dust, pulverized scale or heavy cinder. The other plug 13 or 17, as the case may be, is then screwed into position.
The modified form of construction shown in Figs. 3 and 4 of the drawings Will be readily understood. The head or plug 21 is preferably made with slightly tapered sides 22, as shown, and with a lug 23 perforated at 24, as before described. The lower plug 25 is similar to the plug 21, except that it is unprovided with any projecting lug. 1n this case the threads 11 and 18 are omitted from the shell or body 10 and the plugs 21 and 25 secured in position, as indicated in Fig. 3 of the drawings, by drawing in the end of the tube or body to 'rmly engage them. It will of course be understood that, as before, after one plug is put in position the body is solidly filled with the required filling material and the other plug then placed in position and secured as shown.
l have filed of even date herewith, Serial Nos. 321,132; 321,133 and 321,135 other applications for balance weights formed with mought tubular bodies, and showing different methods of closing the upper and lower, ends thereof. As these closures of the upper and lower ends are independent of each other, it is obvious that they are to a certain extent interchangeable, that is, that the indrawn head of the present application might be used with the form of bottom closure shown in either of the other applications.
lt is of course obvious that 1 do not herein claim anything claimed in any of said applications.
What l claim is l. A balance Weight comprising a tubular wrought body, a separate transversely pierced head made in one piece secured therein, a closed bottom and heavy filler.
2. A balance weight comprising a tubular wrought body, separate end closures made in one piece respectively secured therein, one of said closures having an axially disposed transversely pierced lug, and a heavy filler.
3. A balance weight shell comprising a tubular wrought body interiorly threaded at its ends, and end closures screwed therein, one of said closures having an axially disposed transversely pierced lug.
4. A balance weight shell comprising a tubular Wrought body interiorly threaded at one of its ends, a head closure adapted to be screwed therein and having an axially disposed transversely pierced lug, and means for closingl the other end of said body.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
CHARLES E. POPE.
