April 14, 1931. F. M. wlLLlAMsoN SASH CORD ARRANGEMENT FOR WINDOWS Filed July 13, 1928 lll l INVENTOR Patented Apr. 14, 1931 UNITED STATES FLOYD M. WILLIAMSON, OF DETROIT, MICHIGAN, Assrenon To CROSBY-,Ross WINDOW PATENT OFFICE EQUIPMENT COMPANY, F YPSILANTI, MICHIGAN, A. CORPORATION'OF MICHIGAN SASH-CORD ARRANG-EIVIENT WINDOWS Application med July 13, 1928. serial 1ro. 292,579.
This invention relates to improvements in sash cord arrangements for windows, and refers more particularly to cord arrange ments for windows wherein the sashes are pivotally supported between the slides and are balanced by the cords and the weights on the latter during their pivotal movement between the slides as well as during the vertical movement of the slides and sash. r
In my United States Patent No. 1,671,055 granted on May 22nd, 1928, the slides were provided with rollers around'which the sash cords passed, and the ends of the latter were secured between the sides of the sash and the plates attached to the slides. Such construction however has the following disadvantages: Firstly, in many cases the width of the slides necessitated the use of rollers of such small diameter that they would not opcrate satisfactorily; secondly, the cords were liable to break off near their ends as they were often cut through by the edge of the plates between which and the sides of the sashes they were secured.
The present invention aims to provide a sash cord arrangement wherein cheap, light and easily attached sash cord guides are mounted on the slides, and have, even when employed with very narrow slides, sufficiently large radii to constitute satisfactory bearing surfaces for the cords, and wherein special mounting means are provided on the sides of the sash plates for holding the ends of the cords in such a manner that there is no liability of the latter cutting and breaking ofi'.
Having thus briefly and broadly stated the major purposes and advantages of the invention I will now proceed to describe it in detail with the aid of the accompanying drawings, in which:
Figure 1 illustrates a side elevation of a window with a sash pivotally mounted thereon and partly open.
Figure 2 is a section on the line 2-2 of Figure 1 but showing the sash in nearly closed position.
Figure 3 is a disassembled view of the cord guide and part of the slide, and
Figures 4 and 5 are enlarged side and end views of the cord holder.
a is secured; integral with the latter is a" flange 5. which 'engages the groove 2 when the sash 1s 1n closed position. 1 On the inner side of the slide wall 6 is a longitudinal raised portion 7. i
A cord guide 8 is supported within theslide 1 as by screws 9. One side of this guide rests against the raised portion 7, and pads 10 and 11 at the ends of the guide bear against the inner side ofthe slide wall 6. Avslot 12 eX- tending longitudinally into the upper end of the guide forms a passage for a sash cord 14, and the inner side of this passage continues downwardly and is curved towards its lower end to form a rounded bearing surface 15 for the cord 1li, as the latter is flexed to pass through` a longitudinally slotted opening 16 through the front of the slide. The pads 10 and 11 are intended to prevent air currents from passing through thel hollow slide and entering a room through the opening 16.
The outer end of the sash cord 14 is held in a collar 17 which is rolled after the cord isV in place to insure thelatter being firmly held; and integral with one end of the collar is an eye 18 which is pivotally attached to the side of the plate #l as by a screw 19 which passes through `tl'ie latter and takes into the side of the sash .lhis arrangement permits the collar to turn as the direction of the cord varies due to the amount of the sash opening. Moreover when the sash is closed the collar 17 passes into the opening 16. From the foregoing it will be seen thatthe possibility of the cord being cut by the end of the collar is very remote.
20 designates a stop Secured around the cord 111 to limit the pivotal movement of the sash; when the latter has been swung downwards to a predetermined limit the stop strikes the top of the guide 8 as shown at 20a. When steel sash cord is employed the cord guide is preferably made of a comparatively soft metal composition over whichthe cord will easily slip.
is susceptible to Vsuchmoditications as fall- 15 As the sash 3 and plates 4 are swung pivotally about the slides 1 the weight of the former is counterbalanced by the weights (not shown) on the opposite ends of the sash cords 14, so that the latter are always held taut. Moreover as the sash 3 is raised or lowered the sash cords 14 move upwards and downwards under the cor-d guidewS and e around t-hey A roundedV bearing surface 15 formedl under the latter.
While -in the foregoing the preferred embodiment of the invention has been described Y and shown, it is understood that the invention within the scope ofthe appended claims.
WhatI 'claim as my invention and desire to Y secure by Letters Patent is: n p y 1. A sash cord attachment for swinging windows having a Vhollow casing in which the i window is pivoted; comprising a flat plate-` like guide' member mounted in the casing,v Y elevated Aportions adjacent each end of the guide member abutting the wallof thei'casing,
and a symmetrically curved portion on the guide about which the cord is trained to ride Y thereon (when the window is swung to the open or closed position, the bearing 4surface of said guide being spacedfrom the elevated portions, and the space between one elevated portion and the guide forming a slot through which the sash cord passes. y
Q2. A sash cord attachment for `swinging windows having a hollow casing in which the windowis pivoted; comprising aiat, elongated plate-like guide member formed with a cut-away portion between its ends to reduce its weight, elevated portions adjacent each end of the guide member abutting the wall'of the casing; and a symmetrically curved por-g 4tion on the guide extending lengthwise thereof from one end to a point adjacent the other i endV and about which the sash cord is trained v torride thereon when the windowis swung to the iopen or closed position, the bearing surface of'said guide being spaced from the elevated portions, and the space between one elevated portion and the guide forming a' slot through which the sash cord passes.
