UNITED STATES PATENT FFICE.
FRANCIS MUNN, OF STRATHROY, ASSIGNOR TO WILLIAM THOMSON AND WILLIAM CULVERT, OF TORONTO, ONTARIO7 CANADA.
IMPROVEMENT IN SASH-BALANCES.
Specification forming part of Letters Patent No. 215,281, dated May 13, 187 9; application tiled May 25, 1878.
To all whom it may concern:
Be it known that I, FRANCIS MUNN, of the town of Strathroy, in the county ofMiddleseX and Province of Ontario, Canada, carpenter, have invented certain new and useful Improvements in Sprin g-Regulators for SupportingWindow-Sashes, which improvements are fully set forth in the following specilication and accompanying drawings.
The object of the invention is toprovide a suitable substitute for the weights now commonly used to balance window-sashes; and it consists in the construction and combination Y of the several parts, as hereinafter specilied,
and definitely pointed out in the claim.
The center end of the clock-sprin g fits into a longitudinal slot in the spindle referred to, and its outer end is attached to the periphery of the cylindriform case. One end of a metallic tape of suitable length is similarly attached to and wound around the periphery of this case. The other end is provided with a buckle or clip, which is secured,as shown in the drawings, to the window-sash, the whole being arranged in such a manner that the weight of the sash will be sustained by the spring.
Figure l exhibits application of my sashregulator to a window. Fig. 2 is a detail of bracket. Fig. 3 is a detail of spindle. Fig. 4 shows details of the clip, and Fig. 5 detailsl of the case and cover.
In my invention I make the bracket A of malleable or cast iron, and having the ends of its base-plate rounded, as shown. The jaws A" of this bracket are gracefully formed, and the slotted bearings B cut in them are the proper size to receive the squared or flattened ends of the spindle C. The main diameter of this spindle C should not be less than half an "inch, as a suitable spring can then be more easily attached to it. The inside end, d., of the clock-spring D is bent in toward the end of the said spring,forming the connection between it and the spindle C by entering the longitudinal slot C' in said spindle. Y
The spring D fit-s into the cylindrical case E, which is centrically pivoted upon the spindle C, the ends of which only project outside the case E. The rim of the case Elias a slotted opening, c, into which the outside end, f,
of the spring D tits, as does also the end g of the metallic tape G, the other end of which is provided with a buckle or clip, F, applied for the purpose of connecting the said metallic clip to the window-sash.
Having inserted the spring D and spindle C into the case E, and adjusted these within the bracket A, I wrap the metallic tape G around the case E, to which it is also connected. The regulator is now ready for application, and can in this form be sold to the trade.
The window-frame is cut out to receive the regulator, which is inserted as shown on the right-hand side of Fig. 1, and placed at or about the center of the window-frame. The tape G is wrapped around the case E, :and the clip F is screwed to the bottom of each sash K, as shown in Fig. 1, so that the Weight of the sash K is supported by the strength of the spring. andas the sash is moved the case revolves and the tape unwinds.
As any practical man will understand, two
or more regulators can be attached to each window-sash; but in most cases one will be found sufficient, provided a friction-roller, H, is applied.
Fig. l represents portions of a window-sash and frame to which my attachments are connected. In this ligure Kl is the bottom corner-piece of the sash, and K2 a portion of the sash near the top corner, diagonally opposite to K1, showing how the roller H is applied when only one regulator is used.
I do not confine4 myself to any specific dimensions, as the size will be regulated t0 suit the style of window, whether it be for a house or railway-car.
What I claim as my invention is- The cylindrical case E, having the slot e to receive the outer end, f, of the spring D and the inner end of the tape G, the spindle C, having the longitudinal slot C' and squared ends, and the bracket A, provided with the slotted bearings B to receive the squared ends of the spindle C, combined with the said spring and tape, substantially as specified.
Dated 11th day of April, A. D. 187 8.
FRANCIS MUNN.
