SHADE-ROLLER ATTACHMENT.

Specification of Letters latent.

Patented Nov. 27, 1906.

Application filed June 9, 1906. Serial No. 321,026.

have invented certain new and useful Improvements in Shade-Roller Attachments, of which the following is a specification.

Our invention relates to shade-roller attachments; and its object is to provide a spindle-socket device for the end of a shaderoller that shall be simple and inexpensive in construction and effective in operation.

In preferable form the invention is embodied in the device illustrated in the accompanying drawings and hereinafter described.

In the drawings, in which like figures of reference denote the same parts throughout the several views, Figure 1 is a plan view of the socket-plate embodying the invention. Fig. 2 is a similar view showing the end of an ordinary spring-roller spindle in position therein when the roller is locked. Fig. 3 is a similar view showing the relative position of roller and spindle when the former is moved so as to unlock the catch formed by spindle and socket and permit the spring to roll up the shade or the roller to be pulled down. Fig. 4 is an edge view of the socketplate. Fig. 5 is a plan view of the socket-plate applied to the cup of an ordinary spindle shaderoller attachment, and Fig. 6 is a section through Fig. 5.

Referring to the drawings, 1 is the socketplate, which is preferably formed of a flat disklike piece of metal. It is preferably secured to the end of the ordinary wooden shaderoller by means of the struck-out prongs 2.

The spear 3 or projecting end of the sprin -controlled spindle is adapted to project through and rest in an opening 4 in the socket-plate. This opening is substantially pear-shaped in form, being partly circular and having an eccentric prolongation 5. At the end of this prolonged portion there is formed a hook or tongue 6 projecting inwardly from the inner circumference of the opening and substantially parallel with the diameter of the semicircle of the opening, so as to form a retaining stop or catch for the roller. The spindle is preferably provided with a notch or slot 7, with which the tongue 6 is adapted to engage, so as to lock the roller from turning. The spindle is provided with the usual s uared end 8, adapted to fit in the fixture tiat is fastened to the windowcasing. This squared portion may directly engage the socket, if so desired, and the slots 7 be dispensed with.

Normally the spindle is adapted to rest in the recess formed by the eccentric prolongation 5 behind the tongue 6, the latter there engaging the slot 7 in the fixed spindle and being held therein by the, pressure of the spring, thereby preventing the roller from turning. When the shade is pulled down or jerked, the tongue of the roller will be moved past the slot 7 and the circular part of the roller-opening will rotate around the spindle. When the shade is stopped, the spindle will again project into the elongated portion 5 and the tongue will engage the slot or squared portion and hold the roller securely from turning.

In the usual form of catch device now used for spring-rollers a metal cup on the end of the roller is employed, which cup has a circular opening and has two loose pawls riveted thereon and guided by flanges. The pawls are adapted to engage the squared end of the spindle. These pawls must be stamped out and are applied to the cup by hand. In the present invention the expense and labor of making and applying these pawls and rivets are entirely dispensed with and an equally effective catch device provided.

Instead of securing the socket -plate directly to the end of the wooden roller it may be applied to the cup of the ordinary shaderoller attachment, with the pawls left out, as shown in Figs. 5 and 6. In this case, 9 represents the cup, 10 the ordinary securingferrule, and 11 is the socket-plate secured on said cup and provided with a tongue 12.

It is clear that various modes of securing the socket-plate to the roller may be employed and the shape of the opening varied somewhat without departing from the prin ciple of the invention.

Having thus described our invention, what we claim is 1. In combination with a spring shaderoller, a spindle, a plate on the roller, said plate having an opening surrounding the spindle and provided with an eccentric prolongationwhich engages said spindle when the roller is at rest, and is released therefrom when the roller is rotated so as to carry the plate concentrically around the spindle, substantially as described.

2. In combination with a spring shaderoller, a spindle, a plate on the end of the roller, said plate having an opening through which the spindle extends and bearing loosely on said spindle and having an eccentric prolongation of said opening in which the spindle rests when the roller is at rest and a tongue at the end of said prolongation adapted to engage said spindle, said roller adapted to be released from said spindle when pulled to concentric position whereby the roller may be freely rotated, substan tially as described.

3. In combination with a spring shaderoller and its spindle, a catch for said roller consisting of a disk-like plate having a partly-circular opening with an eccentric prolongation provided with a tongue, said roller resting on said spindle in said prolonged portion by its own weight when the spindle is fixed in the bracket and means on said spindle to engage said tongue, substan tially as described.

4. In combination with a spring shaderoller and its spindle, a catch consisting of a I spindle it is rotated around the same, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
