SHUTTER-WORKER.

, SPECIFICATION formingpart of Letters Patent No. 510,446, dated December 12, 1893.

Applicationfiled December 16, 1891- Serial No. 415,237. (No model.)

To all whom it may concern:

Be it known that I, ALBERT ROSENBERG, a citizen of the United States, residing at Baltimore,in the State of Maryland, have invented certain new and usefullmprovements in Shutter-Workers, of which the following is a specification.

This invention has for its object to provide I a new and improved shutter worker, and it consists in the features of construction and the combinationor arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is an under plan view of thenpper or movable leaf of a butt-hinge provided with a toothed arc and forming part of my improved shutter-worker. Fig. 2 is a side view of the same. Fig. 3 is an edge view and Fig. 4 a side View of the lower or stationary leaf of the butt hinge. Fig. 5 is a face view of the toothed wheel for engaging and operating the toothed are of the upper hinge-leaf. Fig. 6 is a view of the crank shaft with toothed wheel and locking pin. Fig. 7 is a view of a portion of the interior of a window frame showing the position of the shutter-worker with the shutter locked open. Fig. 8 is an elevation of the locking device. Fig. 9 is an end view of the shutter-Worker as seen from the outside of a building when the shutter is closed.

Referring to the drawings, the numeral 1 designates a portion of the wall of a building; 2 a portion of a window frame and 3 a part of a shutter or window blind.

The shutter-worker is connected with and operates the lower hinge of the shutter. The lower or stationary hinge-leaf 4., which is secured to the Window frame as usual, is provided with the usual pintle 5 and with a depending arm 6 having its lower end curved outward away from and out of line with said pintle. In the lower end of this arm 6 is a bearing 7 for a crank shaft 8 that is extended through the Window frame 2 and into the interior of the building. On the inner end of this shaft 8 is a crank 9 and on the outer end of said shaft is secured a toothed wheel 10 through the rotation of which the shutter is opened and closed. The upper or movable hinge-leaf 11 is secured to the sh utter 3 in the usual manner but is preferably provided with a bracing arm 12 that is extended at a right angle to the main portion of the leaf in position to be secured to the outside of the shutter stile. This arm 12 gives additional strength to the hinge and at the same time serves to press the shutter flush up against the sill when the shutter is closed. The upper hinge-leaf 11 is provided with the usual socket 13 for engaging the pintle 5 of the lower leaf. On the lower part of the upper hinge-leaf is cast a toothed are 14 with which the toothed wheel 10 is arranged to mesh. The toothed are 14 is preferably strengthened by a bracket 15 intermediate said are and the main portion of the leaf and integral therewith.

As indicated by the lines X Z, Fig. 9, it will be seen that the center of rotation of the toothed wheel 10 is out of line with the center of rotation of the toothed are 14:, thus adjusting the leverage in such a manner as to greatly facilitate the operation of the shutterworker without straining its several parts. This construction also permits ready removal of the shutter without unscrewing the hingeleaves, and, further, it provides such an arrangement of the toothed wheel 10 that when the shutter is opened'all the way it does not strike against the brick wall, but is prevented from so doing by resting against the said toothed wheel, thereby avoiding the tendency to break off the hinge. This is a very important and desirable feature in this type of shutter workers.

The crank 9 on the inner end of the shaft 8 is provided with a perforation 16 that is countersunk or provided with a recess 17 in its inher end to receive the laterally elongated head 18 of a pin 19 that is loosely supported in said perforation. To the inner side of the window frame 2 is secured a locking plate 20 provided at suitable points with slots 21 into which the head 20 of the pin 19 can be pressed. After the window shutter has been opened or closed, or brought to any intermediate position by means of the shutter-worker, the head of the locking pin 19 can be pressed into one of the slots 21 and be partly turnedtherein to prevent its jarring or working out, and thus the shutter can be easily and quickly locked in the desired position.

It will be observed that when the shutter is closed and locked on the interior it cannot be pried up and lifted out of place, because while the shutter is in this position a portion of the toothed are 14 on the upper leaf of the hinge is below the lower leaf, and by reason of the stout depending arm 6 on said lower hinge leaf any attempt at straining or bending the shaft of the wheel 10 will be prevented.

I am aware that it is common to operate window shutters from the interior of a building by means of toothed gearing rotated by a crank shaft and, also, that looking devices have heretofore been provided for such m echanism; but this I do not broadly claim.

What I claim as my invention is l. The combination of the lower stationary hinge leaf 4 having the pintle 5 and a depending arm 6 provided with a journal hearing at its lower end, the upper movable hinge leaf 11 having the pintle socket 13 and provided on its lower edge with a horizontally arranged toothedarc 14, a shaft 8 extended through the Window frame and through the bearingof the said depending arm on the lower hinge leaf, a toothed wheel 10 secured to the outer end of said shaft in front of the said depending arm to strike the shutter when opened, and means for operating the shaft and looking it in a fixed position, substantially as described.

2. The com binanion of the lower stationary hinge leaf 4: having the pintle 5 and a depending arm 6 extended from below the piutle and havingits lower end portion curved outwardly and provided with a journal bearing 7, the upper movable hinge leaf 11 having a pintle socket 13 and provided on its lower edge with a horizontally arranged toothed are let, the shaft 8 extended through the window frame and through the journal hearing at the lower end of said depending arm, the toothed wheel 10 secured to the outer end of said shaft in mesh with the toothed are so that when the shutter is open it rests against said toothed wheel and is prevented from striking the wall of the building,the crank 9 for operating the said shaft,and means for locking the crank, substantially as described.

In testimony whereof Iaffix my si gnat u rein presence of two Witnesses.
