LEONARD TILTON, OF BROOKLYN, NEV YORK.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 297,032, dated April 15, 1884.

Application filed October 19, 1883.

To all whom, it may concern:

Be it known that I, LEONARD TILTON, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Holder for VVindow-Blinds, of which the following is a full, clear, and exact description.

The object of this invention is to provide a convenient and practical device to be attached to window sills and blinds for holding the blinds at any desired position; and the invention co nsists, principally, of a jointed arm adapted to be attached to the blind, and pivoted to a stud adapted to be secured upon the window-sill, the arm'and stud being provided with means for locking the arm and the sections thereof at any desired position for holding the blind open or closed or at any intermediate position.

The invention also consists of the special means for locking the arm and of the special construction of the device, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 shows in plan view my invention applied to the window sill and blinds. Fig. 2 is a sectional elevation of my new blindholder. Fig. 3 is an inverted sectional plan view taken on the line as w of Fig. 2, the bottom plate, 70, being removed; and Fig. 418 a perspective view, showing the means employed for attaching the outer end of the holder to the blind, and the position the arm assumes when the blind is held entirely open back against the wall of the building.

My new and improved window-blind holder is composed of the jointed arm A and post or stud B, to the pin b of which the arm A is pivoted, and by which stud the device is adapted to be attached to the window-sill O by screws 0 e, passing through the plate 0 of the said stud B, as shown in Fig. 1.

The arm A is composed of the two sections a a, which are hinged together by the pin 93.

The section a is solid and curved outward at its outer end, and formed at its outer end with the upwardly-projecting knob f, which runs between the flanged plates D D, secured to the window-blinds E, as shown'clearly in Fig. 3. The inner pivot end of the section a is en- (No model.)

larged, and formed with the teeth 9 and stop lips h h, for the purposes hereinafter described. The section a ol' the main arm A is not solid, like the section a, but is made hollow, or formed with the downwardly-projecting side plates, a? t. It is also formed with the lugs j j, which are screw-tapped to receive the screws jj, for securing inplace the bottom plate, Ir, for bold ing the slotted sliding dogs G G and springs Z l in place in the said section, as shown in Fig. 2, and in its centerthis section a is cupped, as shownat m, and in this cup is placed the double-acting cam F, which, when turned to the position shown in full lines in Fig. 3, acts simultaneously upon the adjacent ends of the dogs G and G, for forcing them outwardly against the tension of the springs 11, for causing the dog G to engage with the teeth 9 of the section a, and the dog G to engage with the teeth 9, formed in the collar 0 of the stud or post B, for locking the sections a a at any desired position. The springs Z Z are placed in the slots 0 0 of the dogs G G and act between the lugs j j and rear ends of the said slots, so that when the cam F is turned to the position shown in dotted lines in Fig. 3 the springs will force the dogs simultaneously to ward each other, disengaging them from the teeth 9 9, thus leaving the sections a a free to be turned upon their pivots for shifting the position of the blind, the lips h h serving, in connection with the ends of the flanges i i, to limit the pivotal movement of the section a, and the stop-lips h h, formed on collar 0, serving also, inconnection with the opposite ends of said flanges, to limit the pivotal movement of the section a.

The cam F is formed with the opposite corresponding shoulders, 12 p, which act upon the rear ends ofthe dogs G G, for forcing them out ward, and with the stop lips q g, which come against the ends of the dogs for preventing the cam from being turned too far in either direction; and the said cam F is secured to the lower end of the bolt H, 011 the upper end of which is secured the crank I, for operating the bolt, and through it the cam F.

J is a jamnut placed upon the upper end of the bolt H, above the crank I, for locking the bolt H, and consequently the cam F, in the positionshown in full lines in Fig. 3, for locking the sections a a of the arm A in any position The flanged plate D, secured to the blind,-

overhangs the knob f, while the plate Dserves to support the outer end of the section a and to hold the knob f under the plate D, and

- also to furnish a chafe-plate for the outer end of said section to move against in opening and closing the blind, as will be understood from Fig. 4.

hen the blind is to be held closed or at any intermediate position, the section a of the arm A will be held in line with the section a, as shown clearly in Fig. 1.

Constructed in the manner described, it will be seen that the device is very effective for its purpose, is Very convenient, and easily operated.

Although I have shown and described my invention as applied to window-blinds, it will be understood that it is likewise applicable for holding doors and other hinged objects open or closed, or at any desired position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The window-blind holder herein shown and described, consisting of the jointed arm A and stud B, and combined with means, substantially as described, for locking the sections of the arm A, at their pivotal points,-at any desired position, as and for the purposes set forth.

2. The sections a and a, hinged together and to the stud B, the stud being formed with notches g, and the section a with notches g, in combination with the dogs 'G G, springs Z, and cam F, all arranged to operate substantially as set forth.

3. The section a of the arm A, formed with the flanges '1 i, in combination with the section a, formed with the stop-lips h h, substantially as and for the purposes set forth. W

4-. The stud B, formed with lips h it, in combination with the section a of the arm A,for1ned wit-h the flanges 2' i, substantially as and for the purposes set forth.

5. The hollow section a of the arm A, inclosing the sliding dogs G G, and springs Z Z, in combination with the cam F, arranged between the dogs, and adapted to be turned by crank I and locked by jam-nut J, substantially as described.

(5. The cam F, arranged between the'adjar cent ends of the'dogs G G, and formed with the stop-lips q q, substantially as and for the purposes set forth.

LEONARD TILTON.
