SPECIFICATION forming part of Letters Patent No. 599,053, dated February 15, 1898.

Application filed June 18, 1897- Serlal No. 641,284. .(No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. BINGHAM,0f Great Falls, Cascade county, Montana, have invented certain new and useful Improvements in Shutter-Workers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it pertains to make and use the same.

My invention relates to so-called shutter workers and locks combined; and it consists in the peculiar construction, combination, and arrangement of parts hereinafter more fully described.

In the drawings, Figure I is a plan view of a shutter worker and lock combined embodying my invention, showing the device in p0- sition when the shutter is closed and locked.

tending out from the plate 0 and being preferably formed integral therewith.

E represents a so-called spud, which is also secured to the lower end of plate 0 and preferably formed integral with it. The function of the spud Eis to engage in a hole formed in the casing, said hole being of such diameter as that the spud E may be easilydriven therein, thus holding the plate 0 more steady and preventing it from playing or loosening. By using the spud E, I also obviate the necessity of using nails, screws, or like securing devices for securing the plate 0 to the frame or casing; but these devices maybe used also in connection with the spud for securing the plate 0 to the casing, if it is so desired. At the upper end of the plate 0, I provide an opening a of such diameter as to accommodate a hub F and allow said hub to freely revolve or oscillate therein. To the outer end of hub F is secured an arm F, the arm F being so secured to hub F as to move with it. To the lower end of arm F and prefvided with means for securely attaching it to the shutter B. This means may, be bolts, screws, or analogous devices. Engaging the hub F and preferably adj ustably secured therein is a spindle II, the length of which is determined by the depth of the casing, it bein g necessary that this spindle 8, after engaging the hub F in such a manner as to operate it, should extend inward and through the casing of the window-frame far enough to allow of the attachment of an operating-lever J, the operating-lever J being attached to the spindle H either in the manner shown in Fig. II or in any other suitable manner so as to operate said spindle.

The construction of my device for holding or looking the shutter in open or closed position is clearly shown in Fig. II of the drawings,wherein it will be seen that I provide the rack or gear F between its ends with teeth f ff, which are adapted to engage and mesh with the teeth g g g of the segmental gear G. I have shown and described but three of these teeth, but do not mean by this to limit myself to this number, inasmuch as thismay be varied as desired or found convenient. At the outer end of the rack or gear F I provide inclines f f one on either end. These inclines f f are adapted to register with and engage cooperating inclines g g formed on the segmental gear G, and, as illustrated in Fig. I, after the shutter has been closed the two inclinesf, g engage and are tightened by means of a lever J, cooperating through the spindle H, hub F, and arm F to move the rack or gear F thus bringing the shutter up tight or close to the engaging parts of the casin g, holding it there and keeping it from rattling or from being opened.

When the shutter is opened, as illustrated in Fig. I, it will be noticed that the inclines f on the rack F will engage the incline g on the segment G, and as the rack or gear F is moved the inclines will engage more closely, and thus the shutter is locked in open position. It will be perceived that it is only necessary to give to the lever J a partial revolution in order to operate the rack orgear F and thus either open or close the shutter. It will also be noticed that by means of the incline f g and the incline f 9 after the shutter has been closed or opened it is securely locked in either position and prevented from rattling, as in ordinary devices of this kind.

\Vhat I claim is- 1. In a combined shutter worker and lock, the combination with the gear secured to the shutter, of a cooperating rack or gear operated from the interior of the window-casing, said gear and said rack having cooperating inclines,which engage for the purpose of looking the shutter, either in open or closed position, substantially as shown and described.

2. In a combined shutter worker and lock, the combination with the segmental gear secured to the shutter and forming the female portion of the lower hinge of the shutter, a suitable pintle upon which said segmental gear operates and a rack cooperating with said segmental gear for the purpose of operatingthe shutter, said rack being provided upon its ends with inclined surfaces which cooperate with inclines on the segmental gear for the purpose of locking the shutter either in open or closed position,substantially as and for the purpose described.

3. In a combined shutter Worker and lock, the combination with the segmental gear secured to said shutter and revolving around a pintle suitably secured to the casing, of arack cooperating with said segmental gear, said rack being located at the lower end of an arm, the upper end of said arm being secured to a suitable spindle, and through said spindle operated by means of a lever on the interior of the window-casing, substantially as and for the purpose shown and described.

In testimony whereof I sign this specification, in the presence of two witnesses, this 9th day of June, 1897.

GEORGE W. BIN GIIAM.
