RUSSELL G. DUDLEY, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO THE DUDLEY SHUTTER WORKER AND BURGLAR ALARM'OOMPANY, OF NEW YORK, N. Y.

WORKER.

SPECIFICATION forming part of Letters Patent No. 315,393, dated April 7, 1885.

Application filed July 12, 1884. (No model.)

To (1% whom it may concern.-

Be it known that I, RUssELL G. DUDLEY, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Shutter-Workers; and I do 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 appertains to make and use IO the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a face view of I 5 my device. Fig. 2 is also a face view of the inner portion of the window-frame. Fig. 3 is avertical sectional View, and Figs. 4, 5, 6, and 7 are detail views. i

This invention has relation to shutter-work 2o ing mechanism; and it consists in the con struction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims. 1

In the accompanying drawings, the letter A designates the side of the window-casing, and B a shutter connected thereto by hinges 0.

Through the casing is bored apassage, D, at right angles to the plane of the window, and in this passage is fitted a tubular bearin g,

0 E. The outer end of the passage D is enlarged a little, as shown at F, usually forming an interior annular shoulder, G, upon which is secured an annular wear-plate, H.

Through the wear-plate, passage, and bearing E extends the rotary operating-shaft K, the outer end of which is provided with a fork, I, in which is pivoted a turning piece or articulation, J, to which is also pivoted the inner forked end of the short tumbler L, form- By means of a similar double-pivot articulation, J, the outer forked end of the tumbler L, which extends obliquely, is connected to a fork-bolt, m. The articulation-pieces J and J are made with plain bearing-balls (1, preferably, said faces working against the parallel inner surfaces of the fork branches, so that the joints have great strength to withstand the leverage strain.

1? represents a lug having a base, I), which is secured to the shutter; or the lug may be at its base, as indicated at e.

formed on the lower hinge. The lug, however, is in vertical line with thehinge-pivots, and is slotted, as shown at N, to form a hearing for the squared shank s of the fork-bolt m, which is thus rendered capable of adjust- 5 5 ment to bring it in line with the hinge-pivots. The squared shank s of the fork-bolt is formed with a threaded extension, 0, on which is applied a securing-nut, '2, whereby the fork-bolt is firmly attached to the lug P after adjust 6o ment.

The inner end of the operating-shaft K is formed with a seat, 0, for the rocking crank Z, the bearing (1 of which is slightly rounded- The seat a is made large enough to allow play to the crank, which is connected to said seat by a pin. A ratchet-plate, R, having a central bearing aperture, 9, for the inner end of the shaft K, is secured tothe inside of the window-casing. The crank Z is radially'arranged with refer ence to the ratchet-plate, and may be held in any position by engagement with the teeth thereof. A spring, h, is usually provided in connection with the crank to hold the latter 7. in engagement with the ratchet, except when a disengagement is purposely effected in or der to move the shutter. i i Thesedevices are readily applied and will be found strong and effective. ing-rod runs squarely through the casing, it can be fitted to one of the narrowest dimen1 sions without interfering with the weight boxes. I p p I am aware that it is not new to employ a gimbal-joint in connection with a shutter I worker, and I do not, therefore, claim such 9 device, broadly.

I am aware of the patent granted to L. (J. Dion, October 3, 1882, in which a single glmo bal-joint is used to connect the shutter with the operating-rod, the, said rod passing diagonally through a windowcasing, and theref fore do not claim such devices.

Having described this invention, what I 5 claim, and desire to secure by Letters Patent, 1s-

1. In a shutter-worker, the combination, with the operating-shaft K, running horizontally through the casing, of the shutter-lug P, rot

As the operat- 8o the fork-bolt m, and the double gimbal-joint, whereby said shaft is connected to said forkbolt, substantially as specified.

2. In a shutter-worker, the combination, with a shaft running horizontally through the casing, of a double gimbaljoint and devices for connecting the same with a shutter, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
