BEVER-SIBILJEI LOCK HINGE.

To all whom it may concern:

Be it known that I, FRED B. WALTS, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new. and useful Improvements in Reversible Lock Hinges, of which the following is a specification.

This invention relates to reversible lock hinges and -more particularly to easement window hinges.

In is an object of the present invention to provide a simple, practicable, substantial and effective locking means and hinge combination whereby a casement window swinging on a vertical axis may be securely and temporarily fastened in any angular position.

It is also an object to provide a hinge which will enable the window to be swung back practically parallel or close to the con tiguous wall.

Another object is to provide a separable leaf hinge device for right and left hand service and to provide a hinge with the usual pulling or loose pivot pin.

Other objects and advantages will be made manifest in the following specification of an embodiment of the invention illustrated in the accompanying drawings, wherein:

Figure 1 is a plan of a window frame showing a casement window supported by the improved lock hinge.

Figure 2 is a plan showing the easement window swung to full open position and parallel with the adjacent wall.

Figure 3 is an elevation of the hinge with the leaves at an angle to each other.

Figure I} is an edge view of the bearing end of the hinge.

Figure 5 is a side elevation of one leaf member of the hinge, part of .which is broken away.

Figure 6 is a side elevation of the complementary leaf member of the hinge.

Figure 7 is a horizontal section and plan view of the hinge member shown in Figure 5.

The present hingeis' of a type adapted to be used for mounting casement windows, an objectionable feature of the usual mounting for such windows being that the window cannot be conveniently secured in a partially or fully opened position. To overcome this deficiency the hinge device of my present in- .manner of'ordinary butt hinges.

ve'ntion consists of two main leaf members .2,and 3, the former 1n the present case bebolt 7, the screw threads 8 of which project outwardly and are designed to receive a wing or other suitable nut 9. The head of the bolt 7 is designed to healoutwardly against the inner surfaces of the ring parts 5 and 6 and it is adapted to swing around the center of the rings and about the sleeve 2. I

The complementary leaf member 3 of the hinge is proportioned similarly to the member 2 and has axially spaced bearing hubs or sleeves 3* between which may be axially registered the sleeve 2 of the leaf 2 so that the pintle 4: when inserted will connect the leaves in assembled, foldable relation. It is customary to provide a removable pin as 4 and a finishing head or dummy pin 4 is shown as provided in one of the bearings 3 of the hinge leaf 3.

The leaf 3 is provided with a notch 3 in its panel to clear the spaced ring parts 5 and 6 of the hinge leaf. 2 and. is also provided with a segmental finger 10 having a curvaturecorresponding and concentric to the ring members 5 and 6 which are overlapped by the finger 10.

The threaded shank 8 of the 'T-bolt 7 passes outwardly through an aperture 11 in the finger end and thus when the leaves 2 and 3 are relatively folded or unfolded the finger moves about the concentric rings 56. When the sash 2 has been hung on the appropriate hinges and one of these hinges is of the type hereshown, it is possible to term porarily fasten the sash in an opened) or partially opened position simply by tightening up the wing nut 9 so as to clamp the finger against the inner rings 56.

From the above it will beseen that I have provided an extremely simple, inexpensive and practical form of lockable casement window hinge.

Further embodiments, modifications and variations may be resorted to Within the spirit of the invention as here claimed.

What is claimed is:

1. An invertible and reversible hinge comprising a pair of pivotally connected plane leaf members, curved, nesting elements respectively carried by the hinge leaves and being arranged concentric to the axis of the hinge, and means cooperating With the said elements for fastening the hinge leaves in adjusted position.

2. A casement Window hinge comprising pivotally connected fiat leaves, a pair of spaced rings carried by one of the leaves and arranged concentric to the hinge axis, a curved finger member carried by the other hinge leaf and being concentric to said and bearing on rings, and clamping means for binding the rings and finger together.

3. A casement Window hinge comprising leaves pivotally connected, one leaf having a semicircular finger concentric to its axis and the other leaf having a concentric slotted band overlapped by said finger, and a clamp both having a head bearing on the band and a nut bearing externally on the finger and held therein, whereby the band can be rotated on its axis as its leaf is swung and then locked by bolt.

In testimony whereof I have signed my name to this specification.

FRED. B. WALTS.
