LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 283,128, dated August 14, 1883.

Application filed January 9, 1853. (No model.)

To all whom, 1119 may concern.

Be it known that I EGBERT E. MAs E s, of Woodland, county of Yolo, State of California, have invented an Improved Hinge; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful lock-hinge; and itconsists in certain improve ments in the pawl and-ratchet mechanism by which it operates, as I shall hereinafter explain, reference being made to the accompanying drawings, in which Figure 1 is a perspective view of my hinge.

Fig. 2 is a horizontal section, showing its ap hinge and keep the door shut completely, or

plication to frame and door.

The object of my invention is to provide a useful hinge for screen and inside doors, window-blinds, gates, &c., which require to beheld open temporanily.

A is a portion of a'door-fra me, and B a part of a screen-door.

O 0 are the plates of the hinge, screwed to the frame and door. .Upon these plates are flanges or projections forming bearings 0 c,in which the pintle or shaft D is fitted. ings a of plate 0 have their faces formed into ratchets, as shown. Upon the bearings c are formed guides 6, under which aplate, F,is fitted, and is adapted to be moved forward to engage with the ratchetbearings c, orto be withdrawn to free them. When engaged therewith, the hinge is locked in whatever position it happens to be. When the plates 0 O are in line, the locking plate or pawl F may be moved forward to engage with the under or last tooth of the bearings, and thus lock the hinge works freely.

The bear it may engage with any of the teeth, and thus hold the door ajar. When drawn back, the In, the plate F is made an elongated slot, f, in which an eccentric, g, on a shaft, h, is adapted to operate. The shaft h extends through the door, and is bent to form a handle. -By turning this it moves the plate F into or out of engagement with the ratchet-bearings. i

E is a spring on the pintle D, and operating to close the door when the plate F is re leased. s

I am aware that ratchet-bearings operating similarly to mine have been heretofore used; but their ratchets and the means for operating the pawl mechanism are not constructed like mine, which are easy of separation. I I do not claim, broadly, aratchet-hinge, but simply theconstruction I have shown and described. Having thus described my invention, what I claim. as new, and desire to secure by Letters Patent, is-

In a hinge, the plate 0, having ratchet-bearings c, the plate C, having bearings c and guides e, and the pintle or shaft D, passing through bearings c c, in combination with the locking-plate F on plate C, sliding ;in the guides e, and having slot f, the shaft h, and

eccentric 9, all arranged and operating sub' stantially as herein described.

In witness whereof I hereunto set my hand.
