IMPROVEMENT IN CURTAIN-FIXTURES.

Specification forming part of Letters Patent N 0. 120,168, dated October 24, 1871.

To all whom it may concern: The object in forming the spurs in the pecu- Be it known that I, ANTHONY ROELOFS, of liar shape as above described is to enable them the city and county of Philadelphia and State to be readily inserted without splitting the of Pennsylvania, have invented certain Improvewood; also, to cause them, when fully inserted ments in Curtain-Fixtures, of which the followto hold the bracket in a rigid position. The ing is a specification: upper spur e is first driven into the wood, and The first part of my invention relates to the while in the act of driving the lower spur 6 construction of the brackets used in supporting the sharp and front edge of the upper one will the journals of the roller and providing them cut into the wood immediately in front of it, with spurs of peculiar formation for securing thus firmly embedding itself. The lower spur them to the window-frame. The second part of e, which enters in a contrary direction and my invention relates to the application of a guide across the grain of the wood similar to a morto one of the brackets which projects over the tising-chisel, will make an aperture to accompulley to retain the shade-cord continually withmodate itself, and the friction of its square and in the groove. vertical sides against the vertical walls of the Figure l is a side view of my improvement opening will cause it to hold firmly and prein having brackets of curtain-fixtures, showing vent its being drawn out by any ordinary mothe guide attached. Fig. 2 is an edge view of tion of the shade and roller. The bottom part the same. Fig. 3 is a side view of one of the of the spur on a line with the lower part of the brackets as made without the guide. Fig. 4 is boss, being made as broad and flat as possible, an edge view of same. Fig. 5 is a perspective also assists in retaining the bracket in position; View, enlarged, of my improvement in curtainresting, as it does, across the grain of the wood, tures. it forms a steady base, and is not liable to be The hanging bracket A is made in the form pressed down into the wood by the weight of as shown in Figs. 1,2, and 5 of the drawing; the curtain and fixtures, or by the tension of and consists of a hollow semi-spherical boss, b, the cord. The bracket A, Figs. 3 and 4 is used and a shank, c, of suitable length, and is proin supporting the journal at the opposite end vided at the upper end with a spur, d, and at of the roller, and is provided with .spurs simithe lower part with a spur, d.

An arbor, G, formed on the boss for the reception of one of the journals of shank of the bracket A, supports a semicircuthe roller-caps. The spur d at the upper end lar guide, H, which covers the shade-cord where of the shank c is made tapering from the back it passes over the pulley and prevents it from part toward the front, where it terminates in a slipping or flying out of the groove. The said sharp edge on a vertical line with the face of guide should be of such dimensions as to perthe shank, and the back part is inclined at any mit the pulley, while the cord is in the groove, suitable angle to facilitate its insertion in the to be raised within it sufficiently to allow the wood.

If desirable, the arbor G may be dispensed with, and the guide H attached directly on the shank of the bracket.

I do not Wish to broadly claim the securing of the bracket to the window-frame by means of spurs formed on the bracket; but

WVhat I do claim and desire to secure by Letters Patent, is

1. The combination and arrangement of the bracket A, spurs d and d, and guide H all constructed and operating substantially as and for the purpose set forth.

2. The arrangement of the arbor G and guide H on the bracket A, in the manner and for the purpose herein specified.
