SPECIFICATION forming part of Letters Patent No. 459,512, dated September 15, 1891. Application filed January 7, 1891- Serial No. 376,965- (No model.)

To all whom it may concern.-

Be it known that I, ANSON PARKER MER- RILL, of Fall River, in the county of Bristol and State of Massachusetts, have invented 5 certain new and useful Improvements in Shutter-Fasteners; and I do hereby declare that the following is a full, clear, and exact description of the invention,w'hich will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to certain improvements in shutter or door fasteners.

The object of theinvention is to provide an improved automatic fastenerexceedingly simple in construction, thorough, effective, and automatic in action, composed of a minimum number of parts assembled to operate without the employment of springs, and which will operate to lock the shutter or door easily, whether slammed or swung easily.

These objects are accomplished by and my invention consists in certain novel features of construction and in combinations of parts more fully described hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side elevation showing a portion of the shutter or blind or door and the sill, the fastener being locked; Figs. 2 and 3, plan views, portions being broken away, showing, respectively, the fastening device open and the fastening device closed. Fig. 4 is a detail perspective of one of the eccentricallypivoted swinging operating dogs or blocks.

In the drawings, reference-letter 0 indicates the door or shutter, 19 the sill, and c the pin or book carried by the sill or the wall of the house to lock the shutter or door closed or open. The fastener is doublethat is, it is so formed as to automatically lock the shutter either closed or open against the wall of the house.

(Z is the double-pivoted catch or hook of the fastener extending through and projecting from both sides of the shutter and at its opposite ends having the oppositely-extending shoulders e e and beveled, as shown. This double-swinging hook is pivoted at or about the center of its length at b in the metal box f, secured in the rabbeted out portion in the under edge of the shutter. This box is open at both sides, as shown. The shank of the swinging hook is provided with a pair of shoulders 71., located on opposite sides and a distance from the pivotal point of the hook that is, the shank atits center is enlargedlaterally-and these shoulders are form ed by the diagonally-opposite ends of this enlarged portion, whereby each shoulder h is located opposite the engaging or looking shoulder at its respective end of the shank. These shoulders h are preferably rounded to form bearing-surfaces. The pair of blocks or dogs 2' are pivoted in the box, and extend, respectively, to opposite open sides thereof. Each block has an extended inner end provided with a pair of lateral pintles j on opposite 7o sides thereof and integral therewith, fitting in openings in the sides of the box to form journals on which the dog can swing. Outwardly from said pivotal point each dog is enlarged laterally and inwardly, and is provided with the rounded inwardly-extending shoulder 70, bearing against the shoulder 71, of the locking-hook. The outer end of each dog, located opposite its respective shoulderof the hook and a sufficient distance therefromto receive the stationary pin or hook, is preferably cutoff square, as clearly shown. Each locking shoulder or end of the hook is provided with one of these eccentrically-pivoted operating-dogs,

so that whenthe blind moves in either direc- 8 5 tion toward one of the stationary pins or hooks before mentioned the outer edge of the locking-dog will come in contact with said pin, and will thereby be swung inwardly on. its pivot, and its bearing-shoulder 76 will bear 0 against and press shoulder h of the lockinghook and will swing said hook so as to catch said pin between hook and block, thereby locking the blind quickly and easily and noiselessly. It will be readily seen that a blind or shutter will not have to slain or shut very hard or hard enough to be heard in the house before it would catch and if it should swing very hard it would catch just the same.

It will also be seen that the interposition roo consisting of the laterally-swinging hook having the lateral shoulder on one side of its pivotal point, and the laterally-swingin g eccentrically-pivoted dog having a lateral shoulder engaging said shoulder of the hook and having its outer edge adjacent to and located a short distance from the engaging portion of the hook and arranged to operate as set forth.

2. The combination, in a shutter-fastener, of the metal box, the double hook extending therethrough and pivoted therein and having opposite bearing-shoulders on each side of its pivotal point, and the two separate eccentrically-pivoted dogs located in opposite sides of said box and arranged, as set forth, to operate as described, and each having a lateral bearing-shoulder to bear on one of said shoulders of the hook, as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.

ANSON PARKER MERRILL.
