XICHAEL 8'. HMGEBALD, 01 RICHMOND, CALIFORNIA.
LIE-WEIGHTc Specification of Letters rant.
Patented Jan. 20, 1914.
Application m nun :5, 1913. Serial no. 756,662.
To all whom it may consent) Be it known that I, Mueller-L J. Flu-- GERALD, a citizen of the United sta w, residing at Richmond, in the county of Contra Costa and State of California, haveinvented v new and useful Improvements in Sash- Weights, of which the following is a specification.
This invention relates to a sash weight, such as is employed for balancing window sashes.
It is the object of this invention to provide a sash weight which is particularly adapted for use in double hung windows.
A further object is to provide a sash weight which may be so attached to the sash cord as to relieve the latter of sudden strains on the starting and stoppin of the window sash, thlps rendering the sas cord less liable to )rea Further objects will appear hereinaften.
- claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation of a sash weight constructed in accordance with this invention. Fig. 2 is a detail vertical section on the line ma of Fig. 1. Fig. 3 is a detail side elevation of the roller employed in this invention. Fig. 4 is a detail section and elevation of a double hung window of the mullion type, showing the manner of applying the invention.
In the drawings A represents the body of the sash weight, which may be of any suitable construction, but is here shown as consisting of a cylindrical metallic structure which terminates at its upper end in spaced lugs 2. Formed in the lugs 2 are upwardly inclined slots 3 which are open at their lower ends and terminate at their upper ends on the vertical diameter of the weight body A a short distance below the upper ends of the lugs 2. The slots 3 in the lugs 2 are opposite each other, and are designed to receive the ends of a shaft 4, which is any other suitable manner.
engageable with the sides of the lugs 2 to hold the shaft 4 against longitudinal move-. ment. Mounted on the shaft 4 is a wheel 6, provided with a circumferential groove 7, adapted to receive a sash rope 8, as will be later described.
The wheel 6:, is preferably formed of a pair of sheet metal disks, stamped to shape,
which are joined together by rivets 9, or in The plates forming the wheel 6 are bent outwardly at their centers to form recesses adapted to receive rollers 10, arranged to bear upon the peripher of the shaft 4.- The rollers 10 are provide with trunnions 11 on their ends,
which extend through radial slots 12 formed in the wheel 6 and mounted on opposite sides of the wheel .6 are plate springs 13, which bear against the trunnions 11 in such manner as to retain the rollers 10 in contact with the shaft 4, and to provide a resilient bearing for the rollers 10 and the wheel :6. In the present instance I have shown a series of four rollers 10 as mounted in the wheel 6; it being manifest, however, that this number may be increased to any desired extent. It is also obvious that while I have shown plate springs as being employed and providing for resilient bearing for the rollers 10, any other form of construction may be employed by which a yield-able hearing will be obtained. In the application and operation of the invention the sash weight is connected to the sash cord 8, as shown in Fig. 4; that is the provided with collars 5 on its outer end cord 8 is passed around the wheel 6 from the underside, and has one end secured to the sides of a window casing B at C on the interior of the usual channel or box constructed on each side of the sash D, provided for the reception of weights; the other end of the cord being secured to the sash D in the usual manner after passing over direction rollers or sash pulleys E adjacent the upper end of the window frame. From this it will be seen that the weight A is suspended on the cord 8 intermediate the pulley blend the secured end of the cord 8 in such manner,
By the provision of the slidable relation of the weight to the cord, it is possible to.
replace an old worn cord by a new without taking the weight out of its pocket, this being done by attaching the new cord to the end of the old cord after the latter has been detached at one end, then drawing the 'cord through the weight, the new cord being attached at its ends as before described.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. A sash weight, comprising a weighted body portion, spaced lugs on the upper end of said body portion formed with parallel inclined slots, a shaft removably mounted in said slots, and a wheel carried on said shaft.
2. Ina sash weight, the combination with a weighted body 'portion of a shaft removably mounted on the upper end of said body portion, a wheel having a'hollow hub portion and formed with radial slots,'a series of rollers disposed within the hub of the wheel, trunnions on said rollers extending through the radial slots, and spring members mounted on said wheel bearing against said trunnions. i
3. In a sash weight, a weighted body portion, parallel spaced lugs on one end thereof,
having inclined slots open at one end formed 4. In a sash weight, a weighted body por-" tion, parallel spaced lugs on one end thereof,
having inclined slots upon one end formed therein, a shaft adapted to be detachably engaged with said lugs by said slots, collars on the ends of said shaft to prevent longitudinal displacement thereof, a wheel revolubly mounted on said shaft, resilient bearings between said wheel and shaft, comprising a series of rollers adapted to travel on the shaft, trunnions on 'said rollers extending-through radial slots in the hub of the wheel, and springs carried by the wheel bearing against said trunnions. y In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
