SPECIFICATION forming part of Letters Patent No. 554,853, dated February 18, 1896.

Application filed October 7,1895. Serial No. 564,901. (No model.)

To all whom t may concern.:

Be it known that I, HENRY B. ANDERSON, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Swinging Sashes, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming a part of this specification, wherein* Figure 1 is an elevational view of a window, showing the lower sash swung to a horizontal position. Fig. 2 is a vertical sectional view through the same. Fig. 3 is a horizontal sectional view through the swinging frame and lower sash. Fig. 4t is a vertical sectional view showing the upper and lower sashes swung. Fig. 5 is a sectional view on line 5 5, Fig. 4. Fig. G is a detail of the side frame of the sashes. Fig. 7 is a detail view of the swinging frame. Fig. 8 is a detail view of the locking-plate for the swinging frame. Fig. 9 is a sectional view through the sash-cord stays. Fig. 10 is a slightly-modified form of locking-plate for the swinging frame.

This invention relates to a new and useful improvement in swinging sashes; and it consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

Referring to the drawings, A indicates the lower sash and B the upper sash, which are of any ordinary or approved construction.

C and D indicate the sash-cords for the several sashes, which cords run in grooves a formed in the casing, and over pulleys at the top of the casing into the weight-box, where they are weighted as usual. In order to retain these cords in their grooves, I prefer to arrange a guide-roller over them, as shown in Figs. 4 and 5 and as indicated at E. The lower ends of the cords are knotted as usual, the knot being received in a sash-cord stay in the form of a boX F which is countersunk into the sashes, said box having a contracted opening with a rounded bearing edge,on which are mounted movable wear-surfaces ]",.to pre vent the cord from chang when the sash is being swung.

G indicates swinging frames which are piv- Oted at each side of the casing by pivot-screws g which are preferably received in blocks g'. These frames are pivoted about the center of the lower sash, when the same is down, in order that the lower sash may be swung independently of the upper sash, as shown in Fig. l, or, by placing both sashes within the limits of the frame, both may be swung, as shown in Fig. 4. The frame G consists of a plate H, the edges of which are described from the pivot-point of the frame. This plate is preferably lush with the casing, so as to oder no obstruction to the movement of the sashes when the same are being moved vertically, the casing being countersunk for this purpose, as shown in Fig. 4.

Iindicates the outer guide-strip, J the parting-strip, and K the inner molding, which are attached to or which form a part of plate H. These strips, when the frame is in a vertical position, form a continuation of corresponding strips on the casing. In this manner the sashes can be raised and lowered, as usual in common forms of windows.

The plate H is formed with open-ended slots 71. in its upper edge, located between the outer guide-strip and the parting-strip, and parting-strip and inner molding, respectively, said open-ended slots receiving the protruding ends of the boxes F on the sashes, and also `affording a working space for the sash-cords.

In this manner, when either of the sashes are down, the protruding ends of boxes F rest in the bottoms of the open-ended slots and form stops for the sashes, limiting their downward movement. An additional stop for the sashes is provided at the lower end of the partingstrip, where projections j extend from each side of the parting-strip in the path of the sashes.

To hold the frame in a vertical position I provide locking-plates L on each side of the casing, which are adapted to be slid out in front of the frame to lock it in its vertical position, as shown in Fig. 3, or to hold the frame in its swung position, as shown in Fig. 4, said locking-plate being withdrawn from the path of the frame to permit the same to be swung.

In Fig. l0 I have shown a slightly-modiiied form of locking-plate to be used on the outside of the casing, in which instance I prefer to provide the same with slots m, by which it IOO Vin Fig. 4.

is slidingly mounted on the casing, the edge of the plate being beveled to engage a dovetailed recess in the casing.

The operation of the device is as follows: Assuming the swinging frame to be in position and the sashes in place, as shown in Fig. 2, if it is desired to swing thelower sash the locking-plates L are withdrawn from the path of the frame and the same swung. If it is desired to use a screen or an extra outer sash, as indicated at N, Fig. l, the same may be inserted between the outer strip and partingstrip andthe frame swung to its vertical position, when the lower sash may be operated, as is common. If it is desired to swing the upper and lower sashes together, the upper sashis lowered and the two swung, asshown Vhen the sashes 4are in theposi-` tion shown in Fig. A, the weights on the sashcord hold them in place, as the tendency of the cords is to raise the sashes.

The casing is cutaway, as atO, Figs. 3 and 4, to permit the free movement of the sashcords, and in orderv to prevent the sash-cords from chaiing against the frame-plate H, I

`string a loose sleeve P thereomwhich contacts with the frame-plate and saves the cords. The recessed portion `O in the casing extends to the front edge thereof, so `that `the sashes may be withdrawn from the frame at will.

Having thus described'iny invention, what I claim, and desire to secure byLetters Pattilted, and projections on thelower ends-of i l. The combination with a window--casing, which isgrooved for the sash-cords,vrollers which extend across said grooves to hold the sash-cords inplace, frames pivoted in each side of the easing, said casing being recessed beneath the frames to accommodate the movement of the sash-cords when the yframes are vK,and sashes having boxes F with protruding ends adapted to extend into the openended slots,` saidboxes having loose wearsleeves to prevent chaiing of the sash-cords which are secured therein; substantially as described.

4. The combinationwith awindow-casing,

of `frames Hppivoted in each side thereof,

strips I, J, andK Fixed to said swinging frames and extending above;` and below said frames,

.said frames beingiormed with open-ended slots4 between the strips, andprojectionsy' on the lowerends of strips J substantially as described.

The combination with a window-sash, of

. a hollowboxwhich is adapted to receive and `secure .the end of the sash-cord andto beinserted in the-side of `the sash, said box having a contracted opening with rounded edges,

Lan antichaiing-sleeveL arranged in said contracted opening,;z and a` loose antichaingsleeve strung onthe Sash-cord; substantially as described.

6. The combination withl awindow-casing, of swinging frames pivoted in each side thereof, .said frames comprising plates II, yand strips l, J, .andIQand sliding locking-plates arranged in the casing to co-operate with the stripsK torholdthe frames in a vertical position, vand` with the strips J to hold the frames Ain a tilted position; substantially as described.

In testimony whereof I hereunto aiiix my signature, inipresence of two witnesses`,`this 30th day of September, 1895.
