' CHARLES J EANNIN, OF WATERIBURY, CONNECTICUT.

WINDOW-BLIND ADJUSTER AND HOLDER.

To all who'm it may concern:

Be it known that I, CHARLES JEANNIN, a citizen of the Republic of Switzerland, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Window-Blind Adjusters and Holders, of

which the following is a specification.

The present invention relates to an improved window blind adjuster and holder, designed particularly for use in connection with the window blinds of residences or dwellings,'or other places where such a device is applicable.

The primary object of the invention is the provision of a device used in connection with each of a pair of windowblinds, and operable from the interior of the house, to swing the blinds to adjusted or desired position, and to hold the blinds when so adjusted so that theymay not be swung by the wind, and the blinds are prevented from rattling or making undesirable noises, be-

cause of the fact that they are retained in a rigid immovable position.

The invention consists in certain novel combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the. best mode I have so far devised for. the practical application of the principles of the invention;

Figure l is an outside elevation view of a window and its blinds, showing one of the blinds closed, and another one partly open. Fig. 2 is a horizontal sectional view of Fig. 1, showing both blinds closed. Fig. 3 is an enlarged view in sideelevation, showing the operating parts of my blind opener, some parts being shown in section. Fig. 4 is a sectional view of Fig. 3 at line 44. Fig. 5 is a face view of the operatlng handle or knob. Fig. 6 is a face view of the adjustment plate. Fig. 7 is a view in side elevation showing the actuating device of the invention with the elements thereof separated.

For the purpose of illustrating the application of my invention, I have shown an exemplification ofa window frame 1, equipped with the upper and lower window sashes 2 and 3, respectively, while the two blinds 44 are hinged at 55, to swing outwardly from the window, and a pair of leaf Specification of Letters Patent.

device, and these are indicated as incased within the housings 7 and Sin Fig. 1, where the housings are'shown secured to the win- I dow sill 9. similar construction and, therefore, a description of one will suffice for both. Each window blind is equipped with a bevel gear wheel 10 whose stem 11 is fixed in a retain- The operating devices are of i ing strap 12 that is secured rigidly and firmly to the blind near its lower end. Each of the bevel gear wheels 10 is'provided with a stud or pin 13 projecting into the body of the strap 12 so that the bevel wheel 10 will turn with the swinging movement of the window blind. It will be noted that the two hinge joints 55 of the blind and the axis of the stem 11 are invertical alinement, so that the bevel gear wheel 10 will revolve or rotate as the window blind swings on its hinges. To

permit the stud or pin 13 to swing about its axis, the housings 7 V and 8 are provided with circular slots 14.

To accomplish the swinging motion of the window blind, I employ an actuating device which extends from the outside of the window sill 9 inwardly to the interior of the room with which the blinds to the window sashes are used. These actuating devices comprise a sectional. rod, preferably cylin: drical in cross section, and made up of the portions 15, 16 and 17. The joint between the portion 15 and its reduced extension 17 7 forms afshoulder 15, and the two portions 15 and 16 are cut away at 18 and 19 in order to form' flat faces complementary to each other, and adapted for frictional contact with each other. By this construction whereby the ends of the two bar sections 15, 16 overlap each other, it will readily be seen that the length of the operating bar may be varied within limits to suit the width of the wall of the house in which the device is used, and yet preserve the function of the bar and permit its rotation. At the end of the bar section 16, a bevel gear wheel 20 is fixed which meshes with the bevel gear wheel 10, and at the other end of the operating bar a knob 21 is located. This knob has a base 22,

and isperforated at 23 so that the opening 24 in the reduced extension 17 of the operating bar, alines with the opening 23, and the handle or knob is fixed to the extension 17, which'enters 'a socket 23, by means of a pin 25 passing through the openings 28 and 24:. In this manner the wheel 20, when the handle or knob 21 is turned,will rotate the bevel wheel 10. The head 22 of the knob 21 is provided'with a single pinor'stud 26, and 7 this stud is adapted to co-act with the circular plate 27 to adjust the position of the window blind. The platej27 isfperforated to accommodate the extension bar 17, and

the plate is secured by means .of the lugs 28 and screws 29, to the inner face of the'wall just below the Window sill. "Upon the face of the adjustment plate or disk 27, are arranged in circular form a series of sockets 30, any one of which is adapted to receive the pin 26 of the handle 21, so that the operating bar may be turned by utilizing the handle or knob 21, and the pin 26 may be seated a selected socket 30. g

The "operating bar is preferably incased within a cylindrical sleeve or barrel 31, and thisbar is provided with a head 33 counter bored to form a cupf34=. Thehead is preferably provided with prongs or pointed studs 35 toengage the material inwhich the sleeve 7 is embedded and holdsv the sleeve against displacement. Within the sleeve, confined between the shoulder 15 and the adjustment plate 27, is a spring 36 which surrounds the reduced extension bar 17, and holds the handle 21 in plaoewith'the pin 26 in its socket 30. A second spring 38 is located between the reariof the bevel gear wheel-20 and the "face, 39'of the counter bore head 33,-and it will. be seen that this spring holds the head 20 in mesh with the head. 10. V

The operation of the device will be evident from an inspection of the drawings. When it desired to swing the blind on its hinges, the knob or handle 21 is first pulled to the left in Fig. 3, to withdraw the pin'26 from the socket 30. This action. moves the bar section relation to thesection 16, the

distance the handle 21 is pulled from the adjustment plate 27, and the flat faces of the cut away portions 18, 19, glide over each other, but remain in frictional contact. The entire bar may now be turned to the right or left, as required, and this action revolves the bevel gear wheel 20, and through it the wheel 10 is rotated to swing the blind on its hinges as described. lVhen the blind has been swung to the desired position,-the handle 21 is released and the pin 26 is permitted to enter one of the sockets 30 to lock the handle with relation to the adjustment of the plate, the spring 36 returning the section bar 1517, and handle 21 to proper position, and then holding the pin 26 in its socket 30. When in this position it will be evident that the blind cannot be swung in either direction, for it is locked by the engagement of the pin 26 in its socket 30.

From the above description taken in connection with my drawings it is evident that I have provided an efficient device for performing the functions required of the blind bar within said sleeve having a bevel gear in the head engaging said teeth, a spring between the head and gear coiled about the end of the bar, an adjustment plate secured to the end of the sleeve opposite the bevel gear, a circular series of slots on the plate, and saidsectional bar having a reduced portion supported in the plate, a spring between said. plate and a shoulder on thebar and coiled about the reduced portion, a knob fixed at the end of the reduced portion, and a locking pin on the knob adapted to engage one of said series of sockets.

In testimony whereof I afiix my signature.
