BLIND-OPENER AND LATCH CONTROL.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed June 4, 1914. Serial No. 842,852.

To all whom it may concern:

Be it known that I, EDWARD S. JONES, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented new and useful Improvements in Blind-Openers and Latch Controls, of which the following is a specification.

The invention has for an object to provide an improved means for controlling window blinds of the common pivoted type, operable from within a room, without requiring the opening of a window, which will be cheap to manufacture and install, yet efiicient and durable. A particular object is to give a new means for operating a latch by which the shutter is secured at its swinging edge,

operable automatically under manipulation of the opening and closing device. A further important purpose is to provide a simple and eflective means for securing the blinds at various stages of their movement. I am familiar with the patent to Price, 659,419, which, however, does not secure the shutter in the manner I disclose, and utilizes a more expensive construction for controlling the adjustment of the blinds.

Additional objects, advantages and features of invention will appear, some of which will be apparent in the construction, arrangement and combination of parts hereinafter set forth, and shown in the drawings, in which,

Figure 1 is an interior elevation of a window having one embodiment of my invention incorporated therein.

Fig. 2 is a top view of the mechanism with the sill removed.

Fig. 3 is a similar View showing the de vice'in open position.

Fig. 4 is a cross section of the construc tion.

Fig. 5 is a fragmentary plan view showing the shutter open.

There is illustrated a window frame 10, which, except for the sill, may be of the usual construction. The outward appearance and form of the exterior part of the frame are conventional, and half blinds 11 are hinged at opposite sides of the frame in the familiar way, the blinds being also of ordinary construction.

The sill comprises the base member 12 and the top boards 13 spaced thereabove, although it is not essential that the member 12 form an attached part of the window frame, and it may be set in the brickwork or other wall construction. An outer facing member 14 at the outer side is provided, which may be of any desired material, and an inner facing board 15 is shown. I

Mounted on the member 12 adjacent each side of the frame there are horizontal shafts 16, carried by suitable castings 17 fixed upon the member .12, the shafts projecting through the facing 15, immediately beyond which spur wheels 18 are secured thereon, and suitable operating cranks 19 attached. At the outer end of the shaft 16which extends transversely of the sill to a point just without the plane of the lower sash of the window,-there is fixed a beveled gear 20, meshed with a similar gear 21 fixed upon a vertical shaft 22, mounted suitably upon the same casting which supports the outer end of the shaft 16. The shaft 22 extends a short distance above the sill at the outer part, beyond the path of the sash, and is provided with an arm 23 projected horizontally close over the sill and of a length to reach beyond the pivot of the shutter a suitable distance for the purposes hereinafter set forth. The arm is provided with a horizontally disposed elongated eye piece 24 at its outer end engaged slidably on a horizontal guide rod 25 fixed to the inner side of the blind 11 at the adjacent side of the window and offset from the blind in parallel relation thereto. This rod is of sufficient length to allow movement of the eye 24 thereon throughout oscillation of the blind on its pivot. To enable the arm to readily swing with the blind to the outer limit of its movement it may be necessary to form a bend such as shown at 26 therein to accommodate the heel of the blind. The rod 25 is spaced sufliciently from the blind to allow full inward movement of the eye 24 toward the blind. It will be seen from the foregoing that by rotation of the cranks 19 the blinds may be moved in either direction. 4

Immediately adjacent the wheels 18 there are mounted sliding bolts 27 shaped and disposed so as to engage the wheels respectively at one limit of movement of the bolts to hold them against rotation. By this means the blinds may be secured at any stage of their movement with great ease.

The eye piece 24 is provided with an inclined latch lift 28, extending inwardly and upwardly, and pivoted on the blind immediately outward thereof there is a latch 29, having a downwardly projecting bill 30, arranged to engage inwardly of a stop 31 fixed on the sill to receive the bill thereover when the blind is at the inner limit of its movement. The latch has a laterally projected lug or finger 32, extended well over the lift 28 and resting thereon. Under inward movement of the arm 23, the eye moves inwardly on the rod 25that is to say, away from th blindallowing the latch to fall into engaging position, and'its outer side being formed with a properly inclined face to ride over the stop 31, it will engage inwardly thereof as soon as the blind is moved fully to closed position. Under outward bearing movement of the arm 23, the lift 28 will fend the latch upwardly before the rod 25 is engaged to move the blind whereby liability of binding of the latch is reduced. It will be seen that whenever the blind is fully closed it becomes automatically locked to the sill, so that no strain will be communicated to the controlling mechanism in the event that an attempt is made to force the blind open by other means, minimizing the liability of derangement or breakage.

'What is claimed:

A latch and connection for appliances of the character described comprising a horizontal guide rod a pivoted arm, a transversely slotted member having said rod movement of the eye longitudinally of the rod and transversely thereof, a pivoted latch having a lifting laterally projected lug, and a diagonal lift member carried by said arm inclined and arranged to engage beneath the lug under outward movement of the arm on said guide rod, for lifting of the latch in the initial movement of the arm in one direction.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

EDWARD S. JONES.
