Specification of Letters Patent.

Patented July 3,1906.

Application filed December 28. 1904:. Serial No. 238621.

To all whom it may concern:

Be it known that we, WILLIAM H. MULLINS and WILL O. HARE, residents of Salem, in the of sash chains or cords. attached to balancingweights, each sash usually being hung on two sash-chains attached to separate weights which move in the jamb-boxes' at the sides of the window.

Our invention applies especially to any form of window in which the sash is mounted so as to slide both vertically and revolve on horizontal pivots to open the same, which type of window is largely used in metal fireproof constructions. If windows of this character were hung on chains attached to two separate weights, one on each side of the jamb, there would be constant liability that the window would not. move vertically when swung on its pivots to partially or wholly open the same. If one of the weights were even sli htly heavier than the other, when the win ow was swung on its pivots there wouldbe nothing to prevent one side from going up much farther than the other, and thus throw the sash out of its pivot-sockets and cause damage.

Our inventionis applied to windows of the character specified and provides a construc- -.-tion whereby both sides of the sash are compolled to travel parallel, even if the sash stands open on its pivots. To this end we provide a construction of frame-head and pulleys therein such as will permit each sash to be hung from a single balancing-weight, the chains or cords from both sides of each sash being attached to the one weight, this being possible by passing one of the chains or cords through the frame-head and over suitstructiomsuch'as the'frameehead box proably-mounted guiding or hanging pulleys 0rv sheaves.

The inventlon also comprises'ydetalls of convided with a removable bottom plate in order that the suspending pulleys and chains may be readily accessible and also in a form of hanger for the pulleys or sheaves which is strong and cheap of construction.

In the accompanying drawings, Figure 1 is a vertical section taken transversely through the glass, showing a window constructed according to our invention. I Fig. 2 is a vertical section taken parallel with the glass. Fig. 3 is a diagrammatic plan View showing the arrangement of the hanging pulleys and chains. Fig. 4 is a vertical transverse sectionthrou h the frame-head box, on an enlarged sca e.

Fig. 5 is a horizontal section, on an enlarged scale, through one side of the frame and sash; and Fig. 6 is a perspective view of one of the ban ers.

T e window-frame is shown at 1 and is provided on both sides with the jamb-boxes 2, in which move the suspending weights. .3 and 4. 'The upper portion or head of the window-frame is formed as a hollow box 5, in which are mounted the pulleys for the sash cords or chains. The lower sash is shown at 6 and the upper sash at 7. These sashes instead of sliding directly in the jambs of the wlndow are mounted on horizontal pivots ortrunnions 8, secured to weather-bars 9, which slide in the usual jambs of the window, and to which bars the suspending cords or chains are fastened.

All of the parts so far described will preferably be formed of metal, as shown in the drawings, and maybe of the usual or any desired form of meta -window construction having sashes so mounted as to both slide vertically and revolve on horizontal pivots in order to open. The specific form of weatherbar and pivot construction shown is the same as shown and claimed in the patent to Henry C. Nelson, N o. 7 51,747, dated February 9, 1904. This, however, has been selected for purposes of illustration largely, as the invention is applicable to any other construction of weather-bar and sash pivoted thereto.

To the lower sash are connected the chains 10 and 11, the former of which passes over an overhead pulley 12 .and is connected to the Weight 3, while the chain 11 passes over the pulley 13, thence across through the box 5 and over a guide-pulley 14 and is attached to the same weight 3. The upper sash likewise has connected theretotwo chains 15 and 16, the former of which passes over the pulle 17 and rob is attached to the weight '4, while t e'chainf 3, to correspondwith the direction of the chains through the box 5.

The several suspending and guide pulleys described are hung from overhead from suitable head-platcs 20, which are secured. to the top of the head-box 5. Each of these headplates is provided with three pairs of slots 21. The hangers comprise straps 22, bent into U shape and having their legs 23 passing down through the slots 21 and their bases resting upon the upper face of the head-plates. 1f desired,-they may be secured to the plates by means of rivets 24. or like fastenin means.

The bottom plate 25 of the headox is so attached that it is readily removable in order that the overhead pulleys and chains may be accessible when desired. This may be accomplished in various ways. As shown in the drawings, the head-box is provided with a pair oftrausverse bars or brackets 26, secured to the sides thereof, and to which transverse bars the bottom plate 25 is secured by suitable means, such as the tap-screws 27. moving these screws the bottom plate 25 of the head-box maybe removed and access had to the interior of said box.

It will be observed that by our construc tion both Weather-bars, to which the sash is attached, are compelled to move in unison and in exact parallelism, so that even when the Window stands open both trunnions will be at exactly the same height. As a conse quence the trunnions cannot be thrown out of their sockets or otherwise damaged. The head-box and hangers are so constructed to permit of the attachment of both chains of each sash to a single weight, and the construc tion thereof is simple and strong. All parts are readily accessible for inspection and re pair. The hangers are supported directly by portion of metal of the head-plates in width corresponding to the distance between the logs of the U-shaped hangers, thus giving a firm and strong support therefor.

We are aware that heretofore sliding window-sashes have had both suspending chains or cords attached to a single weight. W e do not, therefore,clair n this construction broadly. As far as we are aware, however, it never has heretofore been proposed to attach a single suspending-weight to both chains or cords of windows having both a sliding and a pivotal or revolving movement, or, in other words, to attach a single Weight to two chains or cords By reconnected to the weather-bars of a revolving window-sash.

What We claim is 1. The combination with a window-frame, of Weather-bars slidably mounted. therein, a sash pivotally mounted on said bars and arranged to swing out of the plane of said bars, a single balancing-weight for suspending said sash, and. a cord or chain attached to. each bar and both connected to said balancing-weight, whereby both weather-bars are caused to travel in unison and the pivoted sash prevented from binding or becoming disconnected from the bars.

2. The combination with a window-frame, of weather-bars slidably mounted therein, a sash pivotally mounted on said bars and arranged to swing out of the plane of said bars;

a single balancing-weight moving in a box inone of the window-j ambs, suspending pulleys or sheaves mounted in the frame-head, and a cord or chain attached to eachbar and both connected to said balancing-weight and the pivoted sash prevented from binding or becoming disconnected from the bars, one of said chains or cords passing across from side to side through the frame-head.

3. The combination with a window-franre, of weather-bars slidably mountedtherein, a sash pivotally mounted on said weath er-bars and arranged to swing out of the plane of said bars, a single balancing-weight moving in a boX in one of the Wil'ldOW-jEIIlbS, suspending pulleys or sheaves mounted in the framehea two on the side on which the weight is located and one on the other side, and a cord or chain attached to each bar and both attached to the single balancing-weight and the pivoted sash prevented from binding or be coming disconnected from the bars, one of said chains passing up and overasuspending or hanging pulley on the same side of the frame-head and thence down to the balancing-weight, and the other guide-chain passing up over a pulley on the same side of the frame-head, thenceacross through said head from side to side and over a suitab e guide-pullay on the opposite side of the frame-head, and thence down and attached to the balancing Weight.

4;. The combina tion with a Window-frame, of weather-bars slidably mounted therein, a sash pivotally mounted 011 said bars and arranged to swing out of the plane of said bars, a single balancing-weight moving in a box in one of the window-jarnbs, a cord or chain attached to each bar and both connected to said single weight, one of said cords passing across through the frame-head from side to side, and Sue ending and guide pulleys for said cords in sai frame-head, two on the side on which the weight is located and one on the other side, the last-named pulley and one of the first-named. pulleys being arranged at an angle.

lates in said box, suspending-pulleys hu ng' rom said head-plate, sash cords or chains passing over said pulleys, and a bottom closin -plate removably secured to said box.

7. metal window-frame head for weightbalanced sashes comprising a cross-box, headlates mounted in said box, suspending-puleys mounted on said head lates, sash cords or chains passing over said pulleys, bars or brackets extending across the lower side of said box, and a bottom closing-plate remov- .ably secured to said bars or brackets.

8. An overhead hanger for sash-cord ulleys and the like comprising a head-p ate, slots cut therethrough, a U-shaped stirrup or hanger having its le s extending down through said slots, and asheave or pulley mounted between said legs.

9. An overhead hanger for sash-cord pulleys and the like comprising a head-plate having a pair of slots cut therethrough, a hanger comprising a U-shaped stirrup having its legs extending through said slots ano its base resting upon that portionof the plate between said slots, and a pulley or sheave mounted between said legs.

' 10. An overhead hanger for sash-cord pulleys and the like comprising a head-plate having a pl rality of pairs of slots out therethroug some of said pairs ofslots eing at an angle to others thereof, U-sha ed hangers having their legs passed throng 1 said pairs of slots and their bases resting upon the portions of the plate between saidslots, and pulleys or sheaves mounted between said legs.

11. In a window, the combination of the frame, sashes mounted therein, weights moving in boxes in the frame-jambs, chains or cords c onnecting said sashes and weights, ulleys over which said chains pass, and rangers for said pulleys com )risin U-shaped stirrups between the le s 0 which said pulleys are mounted, and headlates provided with pairs of slots through w ich the legs of said Uhaped hangers pass with their bases resting upon the metal between said slots.

In testimony whereof we, the said WIL- LIAM H. MULLINs and ILL G. HARE have hereunto set our hands.
