SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 365,357, dated June 21, 1887.

Application tiled Octol-er 25,1886. Serial No. 217,294. (No model.)

To alZ whom it may concern.-

Be it known that I, J AMES WAYLAND, acit-izen of the United States,- residing at Newark, in the county of Essex and SijkttGOfNGW Jersey, have invented certain new and useful Improvements in Shutter-W'orkers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as 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 letters of reference marked thereon, which form a part of this specification.

The object of this invention is to more effectively protect the exposed mechanism of the worker from the clogging effect of ice or snow; to secure a more certain and efficient co operation of parts; to provide increased strength,

whereby the worker can more certainly withstand the effect of wind on the shutter; to re: duce the cost ofconstruction and simplify the device.

The invention consists in the improved shutter-worker having the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters indicate corresponding parts in each of the several figures of the two sheets thereof, Figure 1 is a side elevation of a portion of awindow-fralne having the improvements attached thereto.

Figs. 3 and at are plans of the shutter-sections of said hinge, the former showing the preferred any action of the shutter.

construction. Fig. 5 is a side elevation of the house-section of said hinge. tional view of the operating-bar,taken through Fig. 8 is a front elevation of the interior plate adapted to be secured upon the inner casing of said frame and provide bearings forthe operating-barabove mentioned, and hold the same in a fixed position to resist Fig. 9 is asectional View of an outer plate providing bearings for the outer end of said bar. Fig. 10 is a front elevation of aportion of a shutter and shutter- Figs. 2 and 7 are de- Fig. 6 is a sec frame provided with my improved windowworker; and Figs. 11, 12, and 13 are enlarged details showing certain parts of the same.

In said drawings, a indicates a portion of the sash; b, a portion of the shutter, of any suitable construction; 0, a hinge-section for the house, and d a hingesection secured to the shutter, the last being provided with acogged portion,d,the preferred construction of which is shown in plan in Fig. 3.

6 indicates the operating-bar adapted to engage said cogged portion of the shutter-sec tion, and by a straight backward and forward movement to cause said shutter-section to're-- volve with the shutter upon the co-operating section a. The said operating-bar 0 extends through suitable openings or perforations, ff, in the window-frame, and at the inner end is provided with a suitable handle, 9, by which the said operating-bar is manipulated. The outer end ofsaid bar projects through and from said frame, and is preferably provided with a series of perforations, h h, to receive the cogs dof the hinge. Saidperforat ions extendhori- 7 5 zontally through said bar, as shown in Figs.

1, 2, and 9, said bar being provided at the upper and lower edges with connecting flanges or portions h, which give strength to said bar and protect the openings to a certain extent from the entrance of rain and snow, which, freezing fast, would tend to clog said openings. The said openings extend entirely through the bar. Should they become clogged with frozen moisture, upon the introduction of the cogs at one side the said frozen matter may be readily forced out at the opposite side by said cogs, so that the operation of the device is not interfered with. To prevent said frozen matter from clogging the hingesections d, co-operat- 9o ing with said bar, the same is, at the base of the cogs, provided with blade-like formations d formed by contracting the metal at the base of said cogs to an edge, as shown in Fig. 3. When the cogged or toothed portions of the 5 bar enter the spaces between the cogs, should said spaces be filled with said frozen matter, the same is forced against the said edgesor bladelike formations, and thus is forced out of said spaces, so that the operation of the device at this point also will not be hampered.

WhileI prefer the constructions of the hinge sections d and bar 6 thus specified, other constructions may be employed in connect-ion with other features of this invention.

To hold the operating-bar more firmly and securely into operative engagement with the cogged shutter-section,so that thesaid bar cannot be forced away from said cogged portion when the parts are in motion, I have provided or may provide integral with the hinge-plate a projecting brace, 6, having an anti-friction roller thereon to reduce the friction occasioned in operating the worker,wh ich roller bears on the said bar at a point thereon opposite the point of engagement of said bar with the cogs of the hinge-section.

The housesection of the'hinge c is provided with a suitable perforation, through which the bar 0 extends and finds its bearings.

The inner end of the bar may be provided with a series of notches, j, in its lowercdge, to engage a stop-plate, is, Fig. 1, and limit the longitudinal movement of the operating-bar. This bar may engage said stop-plate automatically under the influence of gravity, or I may, and I prefer to, employ a spring, Z, as by the use of the latter I secure a more certain engagement.

I11 lieu of the notches and cooperating stop it, I prefer to employ an automatic clamping device, (illustrated in Fig. 8,) in which case I provide one side of the bar with longitudinal grooves m, Fig. 7, and on the inner casing of the frame or the bearing-plate n thereon I arrange an eccentric pawl, 0,\vhich is toothed in correspondence with the grooves of the bar and engages the same, substantially as shown in Fig. 8. By means of the co-operating grooves and teeth the eccentric and operatingbar are held in the same general relation, so that the said bar can only be held or clamped when in itslowest position in the bearing-plate when forced down automatically by the spring.

The bar works in a vertical slotin said plate a, and by raising the said bar the pawl,while' still engaging the teeth, is relieved of clamping pressure, so that said bar may be readily movedlongitudinally in the slot. By releasing the hand from the said bar the spring Z acts automatically to depress the bar and the latter causes the pawl to descend with it, so that the said parts are brought again into clamping relation, the bar being pressed hard against the side of the slot.

The operation of the device is apparent, and needs but little explanation. By raising the handle and drawing it out toward the person in the room, the shutter is opened. The reverse action tends to close said shutter. By

raising the handle the bar may be easily moved backward or forward. By releasing the handle the bar drops automatically, and the pawl immediately acts to prevent longitudinal movement of the bar, so that the shut ter may be held at any desired point within the limits of its movement.

Having thus fully described my invention, what I claim as new is- 1. In a shutter-worker, the combination. with an operating-bar, of a cogged section, (1, provided with blade-like conformations at the base of the cogs thereof, substantially as and for the purposes set forth.

2. In a shutter -worl er, the combination of the operating bar having longitudinal grooves, and an eccentric, 0, toothed in correspondence with said grooves.

3. In a. shutter-worker, the COll'llllllZLlllOl],

with the operating-bar, of hinge-sections, one

of which is cogged to engage said operating bar, and the other provided with a projecting brace, 73, carrying an anti-friction roller, said parts being arranged and combined substantially as and for the purposes setforth.

In testimony that I claim the foregoing I have hereunto set my hand this 13th day of October, 1886.
