JQHN W. KING, or NE`W'fY0-RK,BN.Y.
Leners Patent No. 94,006, dated Augus 24, 1869.
IMPRovnn comuni-FIXTURE.
The Schedule referred to in these Letters Patent and making part of the sam.
To all whom 'it may concern.:
ne it known um I, JOHN W. Kme, of the city, county, .and State of New York, have invented anew and usefuliIrnprovement in Curtain-Fixtures; and IV and in the arrangement of the pulley outside of thel bearing, aswill be hereinafter more fullydescribed.
In the accompanying sheet of drawings- Figure l represents a longitudinal view of the roller, with the pivot and journal and pulley, attached and arranged according to my invention. p
Figure 2 is a cross-section of iig. l, through the line x-x.
Similar letters of reference indicate corresponding parts.
A is the upper or curtain-roller.
This roller is usually revolved on pivots'vwhiclr are neast on -metallic disks, which disks are fastened to the ends of the roller by tack-nails or by Woodscrews, driven through such disks into theend of the roller. This is the arrangement at both ends of the roller. At one end the cord-pulley forms the disk, the pivot being outside.
This method of fastening the pulley and pivots to the roller is extremely objectionable, as there is a constant tendency' of the tacks or screws to work out of the end of the wood, thereby loosening the disks and preventing the proper Working of the roller.
Another diculty inseparable from this arrangement is, if the ends (or either of the ends) are not out perfectly square, or at right angles with the rod, the
pivots are vthrown out of true, and the tendency to general disorder in the fixture is constant and imminent.
B is the cord-pulley.
By making a-joul'nal or bearing for the rod between the pulley and the end of the roller, as seen in the drawing, the cord will not catch between the pulley and the pivot-'bearing should it ever get oi' the pulley,
thus another serious objectionv to the common xtnre is obviated.
To make the fastening of the pivot and journal and pulley tothe ends of the rod perfectly secure anddurable, I form one or more ears, B B, ou the disks C C, which ears I fasten to the roller by nails or screws, as seen in the drawing. This prevents any loosening of the dis'ks, and it is immaterial whether the ends of the roller are square or not, the pivots or pivot and jour- .nal will always remain true with the roller.
from the pulley, and should it, by any means, run off the pulley, it cannot catch and become wedged or tarrgled, as it frequently does.
The ordinary curtain-iixture (especially this portion) isso defective that it is really one of the standing annoyances of the household.
By my arrangement, all objections are obviated. The fixture will operate from year to year' with perfect ease and certainty. I
Having thus described my invention, l
I claim as new, and desire to secure by Letters Patentl. The combination, with a cord-pulley and disk, of the journal E and vears B, all fitted together, as and for the purpose specified.
2. The snbject-matter of above clause, in combination with the roller A, the ears B, disk C, and pivot D, arranged on the other end of the roller, as shown and described.
The above specification of my invention signed by me, this 22d day of J uue,.1 869.
JOHN W. KING.
