Patented June 8,1897.

TO JOHN L.

FISKEAND ARTHUR K. SMITH, OF CAMBRIDGE, MASSA- LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 584,239, dated June 8, 1897. Application filed September 14,1896. Serial No. 605,704. (No model.)

To (tZl whom it nut-y concern:

Be it known that I, GUSTAF LIBERT BEEN- STIERNA, a citizen of the United States, and a resident of Boston,in the county of Sufiolk and State of Massachusetts, have invented new and useful Improvements in Lock-Hinges, of which the following, taken in connection with the accompanying drawings,is a specification.

This invention relates to improvements in lock-hinges for blinds or shutters for windows, &c., and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents an outside elevation of a blind or shutter provided with my improved lock-hinge. Fig. 2 represents a partial interior view of the same. Fig. 3 represents an enlarged cross-section on the line 3 3, shown in Fig. 1. Fig. 4 represents a vertical section on the line 4. 4:, shown in Fig. 3. Fig. 5 represents a front view of the lock-hinge, partly shown in section. Fig. 6 represents a bottom plan view of the upper member of the hinge. Fig. 7 represents a top plan view of the lower member of the hinge; and Fig. 8 represents a detail perspective view of the releasing cam and lever for unlockingthe hinge preparatory to swinging the blind or shutter from closed to open position, or vice versa.

Similar letters refer to similar parts wherever they occur on the different parts of the drawin gs.

In the drawings, A represents a windowframe, and 15 represents a blind or shutter hinged thereto by means of my improved lock-hinge, as will hereinafter be more fully shown and described.

My improved lock-hinge consists of a lower member O, secured to the window-franie A and provided with upwardly-projecting taporing teeth or cogs 0, adapted to interlock with corresponding teeth or cogs D on the member D, secured to the blind or shutter B, as shown in the drawings.

The teeth or cogs O and D are arranged inward a slight distance from the outer periphery of the disks, so as to provide a free unobstructed trackway for the cam of the operating or releasing lever, presently to be described.

To the member G is secured a vertical pivotpin G", which is loosely journaled in a vertical cylindrical recess in the member D, as shown in Fig. 4c.

The upper end of the blind or shutter may be provided with a similar lock-hinge; but in practice any well-known hinges may be used at the upper end of the blind or shutter, as shown at E F in Fig. 1.

In practice I prefer to make the interlocking teeth 0 D on the parts 0 D tapering, as shown in Figs. i and 5, so as to insure a more positive lock between said parts when said toothed parts are interlocked and thus prevent rattling.

In connection with this niyimproved lockhinge I use a releasing device which is composed of a spindle G, j ournaled in a recess or bearing in the blind or shutter B and provided at its outer end with a suitable cam or crank projection located between the disks 0 D, as shown in Figs. 3 and 4..

The spindle G is provided with asuitable handle G', by means of which it may be turned for the purpose of raising the blind B sufficiently to cause the toothed members 0 D to be disengaged from each other whenever it is desired to open or close the blind or adjust its position.

By raising the handle or lever G the crank or cam projection g is brought in contact with the upper surface of the lower disk O, thus causing the blind B and its locking-disk D to be raised sufficiently to unlock the said disk D from the lower stationary disk 0, after which the blind may be swung to any desired position and locked simply by letting go the hold on the handle G, when the blind will descend by gravity, so as to cause the toothed members O D to be interlocked.

It is to be observed that the releasing-spindle G is journaled in the blind itself and has its operating-handle G projecting through a slot formed therein. \"Vith this construction the said releasing device is in easy access and can be readily operated from within.

It will be noticed that in this my device I make use of no springs for holding the toothed members 0 D in interlocked positions, as in my device such is accomplished by gravity.

only.

In practice I prefer to provide the upper disk D with a peripheral flange D", which serves as a shield for preventing dust, dirt, snow, or rain from getting in between the teeth of the disks (3 and D, as shown in Figs. 1, 4, 5, and 6.

That I Wish to secure by Letters Patent andclaim is- The herein-described lock-11in ge,consisting of a pair of disks having teeth upon their approaching faces, said teeth being arranged inward away from the outer edges of the disks, one of said disks being secured to a windowframe or the like and the other disk secured to a blind or the like, and a releasing device for said hinge consisting of a spindle journaled on the said blind or the like on a line with the lower disk and having a cam at one GUSTAF LIBER'l REENSTIER-NA.
