COMBINED SLIDABLE AND SWINGING SASH.

SPECIFICATION forming part of Letters Patent No. 613,512, dated November 1, 18918.

Application filed February 25, 1898. vSerial No. 671,558. (No model.)

To a/ZZ whom it may concern,.-

Beit known that I, BERNARD HAUsMANN, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in a Oombined Slidable and Swinging IVindow-Sash;

and I hereby declare the following to be a full, q

clear, and exact description of the same.

My invention relates to a mechanism for sliding window-sashes whereby they can be easily disengaged, so as to turn about hinges and swing inwardly for the purpose of obtaining access to the outside of the sash.

It also comprises details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure l is an interior View of my window. Fig. 2 isa face view of the pulley-stile, showing the chain-locking device. Fig. 3 is a vertical section on line y y of Fig. 4t. Fig. 4 is a horizontal section of my window on line @c of Fig. 3.

The object of my invention is to provide a means for conveniently obtaining access to the exterior surfaces of windows.

In large heavy plate-glass windows, which are frequently more than live feet in width and each sash more than four feet in height, the weight of glass and sash will approximate one hundred pounds, and in the present construction of lofty buildings of from eighteen stories upward the danger and diliiculty in attempting to clean the outside of such windows are apparent.

In my invention I have designed such a combination of the sliding and hinged sash that when the sash is used in the usual manner, sliding vertically, it is perfectly counterbalanced and operates in the manner usual to this class of sash. When it is desired to open it inwardly, the counterbalance-weight upon one side is automatically disengaged and latched, thus allowing the sash to be immediately swung on the hinges by which the opposite stile is iixed.

In the drawings, A represents'the pulley- Stiles; B,the parting-strips between which the upper and lower sashes slide. The weights by which the sash is counterbalanced are here shown as suspended from chains D,which pass over the usual pulleys at the top, and extending down in the channel between the stops and parting-strips. The lower end of the chain is fixed to the detachable sliding sash-stile E. This stile is in the form of a strip of wood having a width equal to the thickness of the sash-stile proper and a thickness a little more than equal to the depth of the stop by which it is held in place, so that when the sash is disengaged from this strip it may swing clear of the stop without contact. The chain D is permanently fixed to the sliding strip E at a suitable point between the top and the bottom. Above this point of attachment a short bar F passes through or is fixed to the chain, lying in a transverse groove made in the slide E, so that when the sash G is -in its normal position one edge of the sash will be hinged to the slide E by hinges, (shown at IL) while the opposite edge will be locked to the slide E as follows:

In the edge of the sash G are fixed the hookbolts I, the shanks of which are parallel with and stand out a short distance from the edge of the sash. These hook-bolts normally drop into locking-loops J, which are xed upon the adjacent faces of the slides E and the edges of the sash, and the slide is thus locked Vinto a single structure. As the weight-chains are connected with the outer faces of these slides it will be manifest that the counterweight always pulling upward will cause the two to remain in engagement and slide up and down together. v

When it is desired to open or swing the sash on its hinges H, a link of the chain is pushed into an open slot K, formed in a plate L, which is permanently fixed in the channel in which thesash and slide move and with the slot approximately a little out of the line of the ordinary travel of the chain. mally travels just in front of this plate L; but when, as before stated, it is desired to disengage the sash from this slide E the chain is pressed into the slot K and then moved to one side under the lip K of this slot, so that when The chain northe sash is again raised it and the slide still move up until the transverse bar F, before described as being fixed to the chain, strikes the under part of the socket-plate L, where it is stopped, and the chain and slide are thus prevented from further movement. By then lifting slightly upon the sash the hook-bolts I IOO are disengaged from the loops J, with which they have been hitherto connected, and the sash is then free to swing away from the slide E on the hinges II. rIhese hinges being on the inner faces of the sash, either concealed or visible, as maybe desired, it will be manifest that the sash will turn inwardly, and the face of the glass will then be exposed for cleaning or other purposes.

To prevent the strip to which the sash is hinged from being pulled out of its place by the weight of the swinging sash, I have shown the strip channeled on both edges, and both the stops and parting-strip, between which it slides, have tongues O, which project into the grooves or channels, and thus hold it in place while the sash is swung inward, but will allow it to slide up and down freely when the two are locked together.

Both sashes can be operated in the same manner. The lower one being first opened inwardly, the upper one can be pulled down to near the bottom of the window-opening, and lthe same operation being effected it can also be opened inwardly, leaving both sashes fully exposed inside of the room.

lVhen the sashes are to be again placed in their normal position, they are first closed, with the swinging edges in line with the slides E and the hook-bolts I in line above the loops to which they are en gageable. The sash then droppin g down,either because the single counterweight upon the hinge side is not sufficient to quite balance it or by pulling a little, if necessary, the hook-bolts will engage the loops in the slides E. The sash is then pulled down sufficiently to disengage the bar F from the stop-plate L, and when it has been withdrawn far enough from the lower edge of this plate the chain can be pushed out of the groove in the plate in which it lies and then drawn out through the channel K, so that itassumes its normal position in the channel in which the sash is movable. The parts are then slidable vertically in the usual manner.

In order to make a tight joint where the sashes close against the sliding strips, I have shown coincident channels and projecting tongues, as at M M', which fit together when the sashes are closed, and thus prevent any water which may beat in passing through the joint between the two. These channels and tongues are so disposed with relation to each other that they easily separate when the sashes are to be swung open.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. In a window-sash, the combination of sliding strips channeled on both edges, parting-strips having tongues adapted to engage one of said channeled edges and stops adapted to engage lthe opposite channeled edge, a sash, one edge of which is hinged to one of said strips, a locking-loop fixed to the opposite strip and a hook-bolt fixed in the edge of the sash and with its Shanks parallel with and separated from said edge, and adapted to interlock with said loop, and counterbalanceweights, the chains of which are fixed to the outer faces of the slidable strips, whereby the window is counterbalanced and the parts are slidable in unison.

2. In a window-sash of the character described, strips slidable in the vertical grooves or channels at the sides of the window-frame, a sash one edge of which is hinged to one of said strips, the other edge provided with hookbolts adapted to engage with corresponding loops in the corresponding strip, counterweight-chains connecting with the exterior faces of the strips whereby the windows are counterbalanced and slidable, astop-barfixed upon one chain, and a plate fixed in the channel in which the strip slides and adapted to be engaged by the stop-bar, whereby the strip is arrested and the sash allowed to be lifted and the hook-bolts disengaged preparatory to opening the sash.

3. In a window-sash of the character described, strips slidable in grooves or channels at the sides of the window-frame, a sash, one edge of which is hinged to the adjacent strip, grooves formed in both of the edges of the strip and tongues projecting inwardly from the stops and from opposite sides of the parting-strip into said grooves whereby the slidable strip is retained in place, and a means comprising a loop on the strip and a hook on the sash with its shank parallel with and separated from the edge thereof for interlocking or disengaging the opposite edge of the sash with the correspondingindependent slidable strip.

In witness whereof I have hereunto set my hand.

BERNARD HAUSMANN.
