POWER DEVICE FOR WINDOW-OPERATORS.
Specification of Letters Patent.
Patented Nov. 1, 1921.
Application filed September 16, 1920. Serial No. 410,727.
T 0 all to from it may concern Be it known that I, JOHN J. PARKER, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Power Devices for Window-Operators, of which the following is a specification.
This invention relates to new and useful improvements in power devices for window sash operators such as are employed for op crating windows at high elevations in factory buildings and like places, and is especially adapted for operating a series of windows when arranged side by side in alinement and connected to be operated simultaneously.
An object of the invention is to simplify the construction of-power devices of this class and to provide a mechanism through which the power is multiplied many times and connected for operating one or more sash with uniformity and ease, and so that the same can be readily opened and closed. A further object is to provide a power device which is simple in construction, embodying a minimum number of parts, and which may be readily attached to a window frame in positionto be manually operated by a suspended chain, or to be operated by a motor or other driving means.
lVith the above and other objects in view, the invention resides and consists in the construction, arrangement and combination of parts as now to be fully described and hereinafter specifically claimed, it being understood that such changes in details of construction and arrangement of parts can be made as fall within the spirit of the invention and within the scope of the claims.
In the accompanying drawing forming a part of this specification, wherein like nu- V merals represent corresponding parts,
Figure 1 shows a perspective View of three windows pivotally hung in frame and provided with window sash operating mechanism to which my improved power device is shown connected for adjusting the window.
Fig. 2 is an enlarged side elevation of the power device shown and applied in Fig. l, and
Fig. 3 is a vertical cross section of the power device on line 33 of Fig. 2, the chain being omitted.
In Fig. 1 of the drawing, 5 represents a window casing and 6 window sash pivotally hung in the openings thereof. The window sash operating mechanism therein shown, is of a well known commercial type, and includes a plurality of arms 7, one or more for each sash, and one end of each of which is pivotally connected to the lower portion of a sash, as indicated at 8, and the other end of each of which is operatively connected at 9 in any desired manner to a longitudinally arranged support rod 10. This supporting rod extends along in front of all of the sash, as shown in Fig. 1. The support rod is, mounted so that it will be capable of moving toward and from the plane of the casing to adjust the several sash, but is held against longitudinal movement, and the operative connections indicated generally by numeral 9 may include suitable clamp devices adapted to adjustably hold each of arms 7 so that each can be initially fixed at any desired distance from the supporting rod as will be understood. The longitudinal movable operating shaft 11, which is preferably made of pipe, is slidably attached to the casing in parallel relation to the bottom face of the casing and the supporting rod, and is adapted to have longitudinal movement only. A link 12 which has one end pivotally fixed to the operating pipe 11 and the other end similarly connected to an operating lever 13 serves to operate the latter in a manner to cause the supporting rod to be moved toward and from the casing for the purpose of opening and closing the sash. One end of this operating lever is hingedly connected to the casing at 14 and the other end is slidably connected at 30 to the support rod so that the latter will be moved in and out as above described by the longitudinal movement of the pipe and through the link and lever connection before mentioned.
The improved and simplified power device of the invention is adapted to impart to the operating pipes 11 their longitudinal or sliding movement, and in part, includes a threaded operating shaft 15. The ends of the shaft are finished to receive the ends of the pipe 11 which are secured thereto by pins 16 as indicated to constitute one continuous operating shaft extending in either direction from the power and adapted to operate sash on either side of the power. If desired but one pipe may be connected to one end only of the operating shaft 15 when the power is located at one end of the line of the sash to be operated. As shown more brackets 17 are attached to the window casing in spaced relation with respect to each other. I Adjustably secured to these L-shaped brackets, as indicated'at 18, are attaching flanges 19 of a housing 20 provided with bearings 21 therein. A wheel 22 located in the housing, is provided with a hub 23 having a threaded opening 24 adapted to aline with the bearings of the housing and to engagingly receive the threaded portion of the operating shaft 15, said shaft being freely arranged in the bearings of the housing. 25 denotes thrust bearings for the wheel hub which are arranged on the threaded portion of the shaft between the wheel and the bearings of the housing. A continuous chain 26 arranged in a groove 27 in the periphery of the wheel is for the purpose of rotating the wheel. Obviously the wheel can be rotated in any desired manner, for example, a motor or other driving means can be used for the purpose. 28 denotes a guide roller for the chain, said guide roller being mounted in the housing and beneath the wheel in position to guide the chain, and 29 are stops arranged at the opposite ends of the threaded portion of the operating shaft to limit the extent of longitudinal movement of said shaft.
It will be at once apparent that since the wheel is mounted in the housing and the housing is fixed to the casing, rotation of the wheel in either direction will cause longitudinal movement of the threaded operating shaft in a corresponding direction, for the reason that the threads of the opening in the hub of the wheel is at all times in engagement with the threaded portion of the operating shaft.
After the operating shaft has been manipulated to place the sash in the desired adjusted position, pressure exerted longi tudinally against the shaft cannot cause the threaded portion of the shaft to slide in the wheel. That is to say, the sash will remain in any position in which placed until a positive rotating force is exerted against the wheel.
It will be apparent that the power device invented by me is a mechanism which multiplies many times the power exerted to operate the sash.
hat I desire to claim is:
1. In combination with a longitudinally movable operating shaft having a threaded portion and adapted to actuate window sash operators, a power device for reciprocating said shaft and comprising a housing having side walls and attaching flanges whereby said housing may be adjustably attached to a window casing, alined bearings in said side walls, the threaded portion of said operating shaft adapted to be mounted in said bearings, an operating wheel mounted in the housing and between the side walls thereof, said operating wheel having threaded .engagement with the threaded portion of said operating. shaft to cause the same to move longitudinally, thrust bearings upon said threaded portion and between said wheel and side walls, a chain upon said operating wheel, and a guide roller for said chain, said guide roller supported beneath said wheel and arranged upon said housing.
2. In combination with a longitudinally movable operating shaft having'a threaded portion and adapted to actuate window sash operators, a power device therefor and comprising a housing having alined bearings in which said operating shaft is adapted to be mounted, means for adjustably attaching the housing to a window casing, an operating wheel mounted in the housing upon and in threadedengagement with the threaded portion of said operating shaft, thrust bearings upon the threaded portion of the operating shaft and between the hub of the wheel and the bearings of the housing, a chain for rotating the wheel, and a guide'roller for the chain, said guide roller mounted in the 7 housing and beneath the wheel.
Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 11th day ofSeptember, A. D., 192 0.
