COUNTERBALANCED WINDOW.

Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed January 29, .1907, Serial No. 354,624. Renewed May 20, 1909. Serial No. 497,329.

To all whom it may concern Be it known that 1, JAMES S. DOYLE, a citizen of the United States, residing in the city, county, and State of New York, have made a certain new and useful Invention in Counterbalanced Windows, of which the following is a specification.

This invention relates to counterbalanced windows.

The object of the invention is to provide a construction of counterbalanced windows which is simple and efficient, and wherein the window may be held in any position to which it may be raised or lowered.

A further objectis to provide means for clamping and releasing the counterbalanced suspending cords whereby the window is raised or lowered automatically, when such cords are released, and are arrested and held in the position occupied thereby when the counterbalance cords are clamped.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, location and relative arrangement of parts, all'as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference signs appearing thereon, Figure l is a view in front elevation of a counterbalanced window embodying the principles of my invention the counter. Fig. 2 is an enlarged view in section on the line 2, 2, Fig. 1, looking in the direction of the arrows. Fig. 3 is a view similar to Fig. 1 showing the counterbalance weights applied to the upper sash. Fig. i is an enlarged detail view in section on the line 4:, 4, Fig. 2 looking in the direction of the arrows. Fig. 5 is a detached detail view of a counterbalance weight. Fig. 6 is a view similar to Fig. 1 showing another arrangement of sash cord clamping or holding device included within the scope of my in vention. Fig. 7 is a view in vertical section showing a modified construction of counterweight and anti-noise device embraced with in the scope of my invention.

The same part is designated by the same reference sign wherever it occurs throughout the several views.

The Window frames in which the sash are mounted to slide up and down are formed shaped to form such bead and channels.

The channels B, receive and guide the sash side bars of one window sash either the upper or the lower, while the bead D, receives and guides the side barsof the. other window sash, said side bars being constructed and properly shaped to conform to the configuration of the channels and beads, or else being received in guiding pieces which are so shaped and conformed, as more fully set forth in my application for patent Serial No. 353,840 filed January 241-, 1907. The channels C, receive and guidethe fitting for the sash curtain or shade. This construction and arrangement of the hollow metallic box girder and window sash is claimed in my application above referred to, and therefore I make no claim thereto herein. The interior of the hollow metallic box girder forms a chamber in which, in accordance with my invention, is accommodated the sash counterbalance weight E, the edges of such weight being suitably shaped to conform to the in terior channel produced in the sides of the box girder bv the formation of the exterior beads C, therein, whereby the counterbalance weight is guided in its up and down travel.

If desired, and in order to prevent undue rattle and noise, the counterbalance weights are provided with holes or recesses in the surfaces thereof which contact with the guiding surfaces of the channels in the box girder in which such weights move, in which holes or recesses are placed some soft material, such as lead, wood or the like, as indicated at F, Fig. 5, and which fillings take the bearing contact with the guide channels of the box girder, and not only reduce the noise and rattle incident to the movements of the countcrweights within the box girders under rough usage, as for instance in the case of windows for street or railwaycars, but also serve to reduce the friction of the up and down sliding movements of such weights.

In Fig. 7, I have shown a modified construction of counterweight and antirattle device wherein a rod A extends through a transverse hole or opening in the counterweight B and carries the blocks or pieces C, at its ends which take the bearing contact with the interior surface of the guiding channel of tie box girder, and which thereby not only serves to guide the counterbalance in its up and down travel but also prevent noise and rattie or the counterweight. Springs D, are interposed between the anti noise bearing bloclrs C, and the weight B, and allow a limited yielding swing of the weight.

It is "obvious that other constructions and arrangements of'coun-terbala-nce weights may be employed, but the forms shown and described are sufficient to illustrate the principles involved, and demonstrate a practic'al arrangement for the employment of suspended counterbalance weights for window sash even in car structures.

The counterweights are connected to window sash by cords Gr. These cords may be arranged and connected in any suitable or convenient manner. In one form of -ar rangement, to which, however, my invention is not to be limited or restricted, the cords G, operate around a pulley H, carried by the counterbalance weight E, and over pulleys J, journaled in the upper end of the box girder, as shown. Thence the cords lead and are secured to the window sash. The particular manner of the arrangement of thesash may be varied throughout a wide range. As shown in Fig. 1, the lower sash L, is'd'esigned to'be raised and lowered, and hence the sash cords G, are conrecte'd to the upper corners of said sash, as at K. Where'the lower sash is moved to effect the opening desired, it may simply be moved upwardlyin the side'guides provided by the channels formed in the box girders, or such sash may be lowered into a pocketcr recess adapted to receive the same. In the drawing, Fig. 1, T have shown the lower sash provided with a glass panel W, in its upper half and an open or grated panel X, in its lower half, and normally, when the window is closed the lower half or grated portion extends into a recess or pocket below the window opening. By raising thesash the grated portion is elevated out of the recess orpochet and affords the desired opening, while the grated panel protects against the danger of accident due to thrusting the hands, arms or head out of the window. This is a particularly desirable construction and arrangement for-street or steam railway cars, and for Pullman or other sleeping cars, in which latter instance the trouble and annoyanceof removable screen sections, such as are customarily employed is avoided. If desired the sash cords may be connected to the upper sash N, at the upper corners thereof, as at M, Fig. 3, whereby the upper sash may be lowered to effect the desired opening, or raised to close such opening.

It is obvious that still other modes of operation of the sash may be adopted where desired or required. I do not desire, therefore to be limited or restricted in this respect.

The relative weights of the counterbalance and of the window sash should be so proportioned that the window sash may be moved easily, smoothly and readily up and down in their guide channels. Where the sash is to be raised to eifect the opening the "counterbalance should overbalance the weight of the sash and the friction of the sash and counterwei ht in their respective guideways or channels, so that when the sash cord is released the sash will rise automatically under the influence of the overbalan'ci-ng weight, and where the sash is to be lowered to effect the opening, whether it be the upper or the lower sash, then the weight of the sash should over-balance the counterweight, and the friction. If desired the weight of the counterbalance may just balance the weight of the sash and the friction, whereby the window sash may be readily and easily moved in its guides and maintained in whatever position to which it may have been moved, as clearly shown in Fig. '3.

The sash cord may be gripped or clamped and released in many specifically different ways. I have shown a simple and ethcient arrangement, to which, however, my invention is not to be limited or restricted, wheren-1 provide blocks or bearings O, on the interior of the hollow box girders, and a wed block P, is arranged to operate betwe n the blocks or bearings O. The runs of the sash cord pass the sides of the wedge block and the adjacent surfaces of the bearing blocks, as clearly shown. By raising the wedge block, the sash cord is released'to permit the sash to move automatir 'cally up or down, as the case may be,0r to be r sed or lowered in its guides, and by lowe lng said wedge block the sash cords are gripped or clamped, thereby holding the sash in the position to which it has been moved. Many other different forms of grip or clamp devices forthe sash cord may be employed without departure from the spirit and scope of my invention. The wedge block P, in the particular form shown, may be operated in many specifically different ways. I have shown a simple and ehicient arrangement for accomplishing the desired object wherein tliewedge block is provided with a transversecam or oval shaped opening in which is arranged a similarly shaped rotatable block Q, with which engages the bent end'lt, ot' a rod S, said bent end extending into a transverse slot or opening V, formed in said cam block. The other end of such rod is connected to one member of a spring clip or hand piece, indicated at T, in Fig. 1, and by the mani nilation ofwhich said rod is projected or moved endwise, thereby causing the bent end It, thereof, which extends into the slot of the cam block Q, to rotate said block so as to raise the wedge block P, thereby releasing the normal gripping action exerted thereby upon the sash cord. When the spring clip or hand piece T, is released the wedge block returns to its initial position and again wedges the sash cord against the blocks 0, thereby gripping and locking the same, and hence holding the sash in the position occupied thereby at the time the spring clip or hand piece T, is released. Where the box girder is so formed as to accommodate a window 011 each side of the same, as in the forms shown in the drawing, two wedge block operating rods S are employed, said rods extending in opposite directions from the box girder casing to spring clips or hand pieces T, independent of each other, and each rod having a bent end projecting into the slot or opening in the cam block, whereby said block may be rotated and the wedge block operated bv either red. This is particularly true where the same counterbalance weight is used for sash in windows on opposite sides of the same box girder, though my invention is not to be limited or restricted in this respect. It will be obvious that the operation of one window will not interfere with the adjacent window since the sash cord at only one side of the adjacent window will be released when any particular window is to be raised or lowcred.

In Fig. 6, T have shown another arrangement of sash cord clamping mechanism embraced within the broad scope of my invention, and wherein the sash cord G, is arranged to pass through a hole or opening in the end of a rod E, mounted to slide or to be projected through a stop guide F, arranged to extend into the box girder A, whereby, by withdrawing the rod E, the sash cord G is drawn or wedged against the end of the stop guide F, and thereby gripped or clamped. The rod E, may be operated by means of a lever G, arranged in suitable position to be grasped and rocked or swing whenever it is desired to open or close the window. This lever is pivotally mounted upon a plate H, having a lug J, serving as a guide for the rod E, and through which said rod passes. A spring K, is interposed between lug J, and a collar L, carried by said rod, the tension of said spring being exerted upon the rod E, in a direction to cause the sash cord to be gripped or clamped. Of course it will be obvious that the same lever G, may be connected to sash cord clamping rods operatively connected thereto on opposite Other forms and constructions of sash cord clamping or gripping devices may be employed without departure from the spirit or scope of my invention.

From the foregoing description it will be seen that I provide an exceedingly simple and eflicient construction and arrangement of counterbalance for windows wherein by simply manipulating a spring clip or hand piece the sash to be raised or lowered is released and moves up or down, as the case may be, and is arrested and held in position by releasing the spring clip or hand piece. Where no sash cord gripping or clamping device is employed and the weight of the counterbalance is so proportioned with reference to the weight of the sash as to hold the sash, in whatever position to which it may be raised or lowered, no sash cord gripping device is necessar as seen in Fig. 3.

While my invention is particularly well adapted for use in steel street or railway cars, it is also applicable to windows generally, wherever used, and I do not desire, therefore to be limited or restricted in respect to the particular situation where the same is to be used.

Having now set forth the object and nature of my invention, and a construction embodying the principles thereof, what I claim as new and useful and of my own invention and desire to secure by Letters Patent is 1. The combination with a hollow metallic box girder having the exterior surfaces of the sides thereof shaped to form guides, a window sash mounted to slide in said guides, a counterweight arranged to move within said box girder, a cord connecting said counterweight and sash, a clamping device arranged and normally operating to engage said cord, and means for releasing said clamp.

2. The combination with a hollow metallic box girder having the side walls thereof shaped to form interior and exterior guide grooves, a window sash fitted to slide in the exterior grooves, a counterweight arranged to operate within the box girder and fitted to slide in the interior guide grooves, connections between the counterweight and the sash and means for clamping and releasing said connections.

3. The combination with a hollow metallic box girder having the sides thereof shaped to form interior and exterior guides, a window sash fitted to the exterior guides, a counterbalance weight arranged to operate within the box girder and fitted to the interior guides, bearing blocks carried by said counterweight, and connections between the counterweight and the sash and means for clamping and releasing said connection.

4. The combination with a hollow metallic box girder having the sides thereof shaped to form guides, a window sash fitted to said guides, a counterweight arranged to operate within the box girder, a cord con meeting said counterweight and sash, and means arranged within the box girder for clamping and releasing said cord.

5. The combination with a hollow metallic box girder having the sides thereof shaped to'form guides, a window sash fitted to said guides, a counterweight arranged to operate within the box girder, a cord connecting said counter weight and sash, means arranged within the box girder for clamping and releasing said cord and means extending outside of said box girder for operating said clamping and releasing means.

In testimony whereof I have signed my name to this'specification, in the presence of two subscribing witnesses, on this 24th'day of January A. D. 1907. JAMES S. DOYLE. Witnesses I. LEVINSON, S. E. DARBY.
