EDWARD F. GOODWVIN, OF TAUNTON, MASSACHUSETTS.

SHUTTER WORKERf EPECIFICATION forming part of Letters Patent No. 375,151, dated December 20, 1887.

Application filed August 1, 1887. Serial No. 245.790. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD F. GOODWIN, a citizen of the United States, residing at Taunton, in the county of Bristol and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Blind- Operators, of which the following is a full, clear, and exact specification.

My invention relates to improvements in blind-operators, whereby the blind may be opened or closed and the blind-slats, by the action of an eccentric, raised or lowered from the inside without opening the window.

Figurel of the accompanying drawings represents a side elevation of the device, the blind being in a perpendicular position relative to the window-frame. Fig. 2 is afront elevation in a direction at right angles to the first, the blind being in the same relative position as before. Fig. 3 is a plan view of the same; Fig. 4, an end view of the handles as they would appear from the inside. Figs. 5 and 6 represent parts of the device for operating the slats. Fig. 7 is a view of the ratchet R and the detent M, the handle E being cut off.

A A is the frame of the blind; H, the part of the lower hinge attached to the wall or window-frame, and H the corresponding part attached to the blind.

B is a bevel-gear forming an integral part of the portion of the hinge H, the axis of the wheel B being in the same vertical line as the axis of the pin it, on which the hinge turns. B works with the corresponding bevel-gear, B, which is connected, by the hollow spindle G, to the handle or bevel-knob E on the inner side of the frame or wall. Inside the hollow spindle G is fitted loosely a smaller solid spinthrough a hole in the center of the bevel-gear B, and the upper rod, K, passing through a hole in the center of the pin h of the lower blind-hinge. The upper end of the rod K is attached in anysuitable way to one end of the lever L, which is pivoted at S, so as to turn freely, the other end of the lever being attached loosely by means of the ring T, or in any other suitable manner, to one end of the blind-slats, as shown.

By turning the larger knob,E, the blind may be opened or closed, suitable means-as by a detent, M, and a ratchet or toothed wheel, R being employed to retain the blind in any de sired position.

The detent M is raised by the fingers while the blind is being moved and shut down when the blind is in the desired position.

By turning the knob D the frame I is raised or lowered through the eccentric or cam O, which, by means of the rod K and lever L, operates the blind slats to close or open them.

YVhat I claim is- 1. A blind-operator consisting of a hollow spindle provided with a handle and suitable means for preventingit from turning, attached to a bevel-gear which works with a corre sponding gear attached to and forming auintegral part of the portion of the hinge mounted on the blind, in combination with a solid spindle passing through the hollow spindle, an eccentric turning in a frame, and a connectinglever attached to the blind-slats, all arranged and operated substantially as set forth.

2. In a blind-operator, the combination of a spindle operating an eccentric, a frame provided with vertical guide-rods, one of which passes through the hollow pin of the portion of the hinge mounted on the wall or windowframe, and a lever attached to the blind'slats, substantially as described.

In witness whereof I have hereunto set my hand. I

ED\VARD F. GOODWIN.
