HINGE FOR CASEMENT-WINDOWS.

- Specification of Letters Patent.

Patented July 5, 1921.

Application filed September 20,1920. Serial No. 411,431.

T 0 all w ham it may concern Be it known that we, VIoroR S. LUNDELL and GusrAr EDWIN EOKBERG, both citizens of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented new and useful Improvements in Hinges for Casement- Windows, of which the following is a specification.

This invention relates to casement windows, and has for its chief characteristic the provision of a novel form of hinge or pivot so that when the window is swung to an opened position, the pivot or hinged side of the window is moved an appreciable distance away from the window casing, thus providing suflicient space to gain access to the outside of the window when it is desired to clean the same.

Another object of importance resides in the provision of a novel construction of means whereby the" window can be locked at any desired angle.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a front elevation of the casement window mounted in accordance with our invention. I

Fig. 2 is an enlarged view showing the opened position of the window, and the space provided between the hinge side thereof and the window casing.

Fig. 3 is an enlarged horizontal sectional view through the lower hinge or pivot showing the window inan opened position.

Fig. 4 is an enlarged vertical sectional view through the hinge.

Fig. 5 is an enlarged sectional View taken on line 55 of Fig. 3.

Fig. 6 is a perspective view of one of the plates secured to top and bottom of the window casing. i

Fig 7 is a similar view cured to the sash.

Fig. 8 is a detail view of the link connec tion.

Fig.9 is a perspective view of the locking lever and cam.

of the plate se- Fig. 10 is an edge elevation thereof.

Fig. 11 is a detail view of the brace with which the cam cooperates for locking the window at different angles.

Fig. 12 is an elevation showing the invention associated with the steel casement.

Fig. 13 is a sectional view showing the closed and opened positions of the window.

Referring to the drawings in detail, 10 indicates generally the window casing, 11 the window sash, which is pivoted at the top and bottom thereof as clearly shown in Fig.1 so that the window is permitted to swing outwardly from one side of the window casing. The pivot or hinge for the window at the top and bottom is identical in construction, except that the lower pivot or hinge has associated therewith a means for locking the window'at any desired angle when opened. I

Secured to the upper and lower part of the window casing, are elongated plates12, each of which is provided with a longitudinally disposed slot 13, a straight fiange l l along one of its longitudinal edges, and a flange 15 extended across one end of the plate and having an inclined surface or edge 16. Each of these plates is also provided with an opening 17 for the purpose to be hereinafter described. Secured to the upper and lower part of the window sash 11 are plates 18 of a somewhat similar confi ration as the plates12, each'plate 18 including flanges 19 extending along the opposed longitudinal edges for a portion of their length, and connected by a flange 20extended across one end of the' plate as shown. These flanges 19 and 20 are arranged to embrace the adjacent sides of the window sash, while depending from the opposite end of the plate 18 is a flange 21 having an inclined surface or edge 22 to cooperate with the corresponding surface of the plate 12. Each plate 18 is provided with an opening 23 similar to the opening 17 of the plate 12, the respective plates of the top and bottom of the window being connected by means of a link 24. The link 24 is provided with pivot lugs 25 projecting from the opposed sides of the links adjacent the ends thereof, and one of these lugs is received by the opening 17 of the plate 12, while the remaining lug is received by the opening 23 of the plate 18.

Carried by each plate 18 is. a pivot 26 which operates within'the slot 13 of the plates 12, that subsequent to swinging the window 11 upon these pivots to its opened position, the window together with the pivot may be moved longitudinally of the plates 12 so as to provide a space between the pivot side of the window and the adjacent side of the window casing, to allow one to project the arms therethrough when it is desired to clean the window. The opened and adjusted position of the window is clearly illustrated in Figs. 2 and 3;

For apurpose of locking the window in any desired angle,we employ a lever 28 which projects horizontally through a slot 29 in a plate 30 secured to the lowermeinber of the window sash. This lever is termed with the end portion 82 which operates in a bore in the lower member of the window sash and which depending portion is pivotally connected with a duplex cam element which is provided with a central opening to receive the pivotabove referred to. The cam is rotatably mounted upon the pivot and actuated through the instrumentality ot the lever 28. Also carried by the pivotand fixed with relation to the cam, is a slate 34 provided with opposed ends 85 disposed to aline with the slot 13 of the adjacent plate 12 so as to move in the slot when the window is adjusted. The upper ends or" the pins are beveled or inclined as at 36 to cooperate with the cam like projection at 87 of the cam to hold the window in a given position. The lever 28 is provided with a loop or finger receiving opening 28 to facilitate the operation of this lever. As shown in Fig. 1 the only part of the mechanism visible is the operating element.

In practice, when the window is in its closed position as shown in Fig; 1, the lever 28 is arranged against the window sash as shown. Nhen it is desired to, open the window, the window is swung upon its pivots at the top and bottom outwardly and subse quently moved in the position shown in Fig. 2, during which time the pivots travel in the slots 13 of the plates 12, thus moving the pivot or hinged side of the window away fromthe adjacent side of the window casin for the purpose above mentioned. It is of course manifest, that the plate and the pin, and the cam associated with the lever move with the pivot, after thewindow has been given the desired angularity with respect to thewindow sill, the lever 23 is moved awayjfrom the window sash, during which time the cam is actuated and moved to active association with the beveled pm at 34. This provides an effective means of holding the window fixed relatively to the window casing. in its adjusted position. The window 7 1s closed-by simply reversing the movements.

ofthese parts. V In Figs; lland 12wehave shown the invention applied tosteel window casement and wherein 88 indicates the slotted member in an adjusted position.

associated with the window casing, and 39 the window. Secured to the window is a strap 40 which is provided with an apertured lug 41 to accommodate the pivot 42 carried by one end of the links 43, the lug 44 carried by the opposite end of the link being pivoted as at 46. The strap is also provided with a pivot 47 which operates in the slot 7 sorted to. when desired as fall within the scope of what is claimed;
