LYDIA J. LANPHEEE, OE WATERLOO, IOWA.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 230,026, dated July 13, 1880. Application filed January 5, 1880.

To all whom t't may concern Be it known that I, LYDIA J. LANPEERE, of Vaterloo, in the county of Black Hawk and State of Iowa, have invented certain new and useful Improvements in Shutter Workers; and I do hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a partofthis specification.

This invention has for its object to furnishv a simple, cheap, and durable shutter-worker.

I will first describe my invention, and then specifically point it out in the claim,

In the drawings, Figures 1 and 2 are horizontal sections of a window frame and shutter with my invent-ion attached thereto, showing the shutter open and closed. Fig. Sis a front view of a portion of a'window frame and shutter with my invention applied thereto.

(t is the windoweasin g. b is the shutter, and c represents the lower hinge of the shutter.

The upper hinge may be of any ordinary form. The invention is applied only to the lower hinge.

The casing a has a horizontal mortise, a', in which is placed a sliding bar, d, on the outer end of which is formed a rack, d. Ihe rack d has the cog cl2 next the last at its outer end formed with a flat top or end, as shown, and has the cog cl3 next the last at its inner end similarly formed. The end cogs ofthe rack have a slightly wider space between them and the cogs d2 d3 than is between the other cogs thereon. The object of this is to permit the fiat-top cogs to pass onto the top of corresponding cogs on the pinion of this hinge, hereinafter described.

The lower leaf, o', of the hinge has a projection and guide-pin, c2, arranged so that the back of the bar d will bear against it. This pin is employed so that less accuracy need be observed in forming the mortise a. The bar can be supported by the side of the mortise;

but this would require great nicety in forming said mortise with reference to the hinge. The use of the pin c2 obviates this exactnessin construction.

On the knuckle c4 of the leaf c3 I form a pinion, e, which is engaged by the rack el on the rack-bar el. On opposite sides of the pinion I form two flat-top cogs, e e2, so arranged that they will engage on the tops of the cogs cl2 cl3, as hereinafter explained.

I have shown the pintle of the hinges c attached to the leaf c3; but this is done for convenience. The pintle may be put on the leaf y o and a hole formed through the pinion c to rest over it.

The operation of the device is very simple. In Fig. 1 the shutter is open and locked by having' the teeth cl2 and .e2 with their ends abutting and the end stop-cog, d4, of the rack-bar pressed against the cog e3 of the pinion. Push the bar cl from the position in Fig. 1 to the position shown in Fig. 2. The cog cl2 will be thrown off the cog e2, and the rack will enga-ge the pinion and turn it, closing the shutter and bringing the end of the cog d3 to abut against the end of the pinion-cog e and the stop-cog d5 against the side of the cog e, thereby looking the shutter.

Havingdescribed myinven tion, what Ici-aim 1s- The combination, with the hinge of a win dow-shutter and the frame a, of the pinion e, iXed to the leaf o3, and having the cogs e e2, formed with ilat ends and arranged as de scribed, and the rack-bar d. having the rack d with the dat-top cogs d2 d3 at its ends, and the stop-cogs Z4 d5, arranged to operate sub stantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I afx my signature in 'presence of two witnesses.

LYDIA J. LANPEEEE.
