LAFAYETTE HUNTQON, OF NATICK, ASSIGNOB TO THE HUNTOON MANU- FACTURING COMPANY, OF BOSTON, MASSACHUSETTS.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 257,711, dated May 9, 1882.

Application filed September 1:2, 1881. (No model.)

provide certain improvements whereby the device is made more convenient and desirable.

It also has for its object to enable a shutterworker adapted to be operated from the inside of a building to be applied to a blind composed of an inner fold hinged to the building and an,

outer fold hinged to the inner fold, so that both folds may be operated simultaneously.

To these ends my invention consists in the several improvements which I will 110w proceed to describe and claim.

Ofthe accompanying drawings, forming par t of this specification, Figure 1 represents a front elevation of a part of a blind and window-casing provided with a' shutter-worker embodying some of my improvements, the position of the blind when open being shown in dotted-lines. Fig. 2 represents a section on line 3 y, Fig. 1. Fig. 3 represents a sectionon line 2 2, Fig. 1. Fig. 4 represents an enlarged section on line or m, Fig. 2. Fig. 5 represents a front elevation of a portion of a'blind composed oftwo-ifolds, a portion of the windoweasing, and my improvements applied thereto. Fig. 6 represents a section on line 2 z, Fig. 5.

The same letters refer to the same parts in all the figures.

In the drawings, B represents a blind hav ing at its lower end a downwardly-projectin g stud, o.

d represents a plate formed on the outer end of an operating-rod, j, which extends through the window-casing to the interior of thebuilding, where it is provided with a knob or handle, k

d represents a slot in the plate d, said slot receiving the blind-stud c. In my former patent referred to both sides of the slot d in plate d are shown straight and substantially at rightangles to the operating-rod f. I have found that when the slot is so formed, in case the blind, in being opened or closed, comes to rest upon a dead-point-i. 0., in a position about at right angles with the wall of the building-the operator cannot move the blind from within by pulling inwardly upon the opcrating-rod, the outer side of the slot which is pressed against the shank o to move the blind from the described position being at right angles to the line of movement of the rod, and therefore unable to exert such pressure upon the shank as will move the blind in either direction. Hence the window has to be opened and the blind moved by hand past the deadpoint. To obviate this objection 1 form upon the outer side of the slot (1 a re-entrant angle or projection, e, composed of two-surfaces,1 1, which meet and form an angle at a point in line with the rod f, said surfaces being diag onal to the rod f.

It will be seen that in case the blind stops on the dead-point an inward pull on the rodf will cause one or the other of the diagonal sur' faces 1 1 to bear upon the stud 0 and impart sufficient lateral pressure thereto to cause the blind to swing in one direction or the other, according to the inclination of the surface 1 which bears upon the stud.

a is a metallic bushing composed ofa cylinder threaded upon its periphery, and provided with a longitudinal orifice to receive the rod f, and with a set-screw, 1), adapted to bear upon the rod and hold it at any desired point. The bushing a is secured into the wall of the room into which the rod f projects, the screwthreaded periphery enablin git to be easily applied.

By means of the set-screw b in connection with the slotted plate d and stud c, I am enabled to secure the blind at any desired angle.

The inner section of the operating-rod f is extended beyond its pivot, (said rod being made in two sections pivoted together at i, as,

shown in my aforesaid Letters Patent No. 241,017.) By thus extending the inner section I enable it to project from both sides of the outer section and extend across the inner end of the bushing a, as shown in Fig. 2,'when said inner section gravitates to its vertical position after the blind has been opened or closed. The inner section is thus enabled to form a stop or look to hold the blind either opened or closed, it being impossible to move the rod f outwardly when the inner section of said rod is in its vertical position.

It will be seen that the end of the bushing formsa bearing for the inner section of the rodf when the latter is in position to lock the blind. It will also be seen that the threaded periphery of the bushing enables the same to be adjusted and to project more or less from the wall of the room, so that variations in the thickness of the wall can readily be compensated for.

My improvement relating to blinds made in two folds (illustrated in Figs. 5 and 6) consists in applying a shutter-working device of the kind above described to the inner t'old, B, which is hinged to the building, and in connecting the outer edge of the outer fold, B, (which is hinged to the inner fold at 8,) to the window-sill A by a rod, f which is pivoted both to the outer fold and to the window-sill, and so arranged that when the inner fold is moved by the operator to close the blind the outer fold will be at the same time extended by the rod f until it is in line with the inner fold, as shown in dotted lines in Fig. 6. When form the lock, said bushing being capable of adjustment in and out, so as to adapt the de- Vice to casings of different thicknesses, sub stantially as described.

2. The combination, witha blind composed of an inner fold hinged" to the building, an outer fold hinged to the inner fold of the stud on theinner fold, of the rod and slotted plate cooperating with said stud, and a rod articulated at one end to the'building and at the other to the outer fold of the blind, whereby said outer fold is operated simultaneously with the inner fold, as set forth. I Y

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 7th day ofSeptember, A. D. 1881.
