Description
ctnited tzrita Letters Patent No. 95,232, dated September 28, 1869; cmtedatczl September 11, 1869.
IMPR'ovJsD SPRING CURTAIN-ROLLER V fighe "Se'zhednle referred to in these Letters Patent and making part of the same.
To all whom fit'ntay conte/rn.-
Beit known that I, EDWARD M. JUDD,-of Wolcottville, inthe county of Litchfield, and YState of Connecticut, have invented and made a certain new and use- .ful Improvement in Spring `Curtain-Rollers; andI do hereby declare thefollowing to be'a full, clear, and exact description of the said invention, reference being 'had to the annexed drawing, making part of' this specication, wherein.-
Figure l is'a longitudinal section of the roller and parts sustaining the helical spring;
'Figure 2 is a view ofthe block for holding'theinner f end 4of the helical spring;
Figure 3 is the ratchetand.stationaryaxis; and,V` Y.
Figure 4 is the diskl that isset into'the end of the roller.
Fignre is an' elevation of the ratchet and stationary axis'. i
Similar marks.ofreferenceidenote the same parts.
Ourtainwixtures have rheretofore been made with a helical wire spring for revolving the 'roller and winding up the curtain. C
In this charactercf curtain-iixtures a pawl has been provided to drop into a notch` or cam-tooth, and hold the shade' or curtain, by preveutingthe roller revolv- In this character of spring-roller-the'stationary axle upon which the roller revolves, has extended through the helical spring, to a block provided at the inner end,
' forming a centre `for said axle,'and also 'holdingmthe inner end of the spring.'
Myjnvention allows the stationaryaxle of the rollery to be short, ,so that the spring will nothave anything inside of. it, and the parts will be more easily e011- Structed and applied.` In the drawing l `a represents the wooden roller, with any ordinary end, la, to revolve in a bracket,`
At the other end of the roller is a holel bored, into 'which the helical spring d is introduced.
The` spring d, previous to its insertion, is attached,
at one end, to the block e, that is of a diameter to fit the interior of the hole in the roller, and there'are proiecting points2 2, cast with the block around its pe riphery, so that the said block c will he firmly fixed to the roller, by driving the saine down into.. the hole inthe roller, and, for this purpose, a metal rod may be introducedlthrough the spring al.
' The stationary axis of the roller. isI made of metal, cast withl the ratchet or cam-disk t', on one side of which the projecting axis 3 is iitted for the outernd ofthe spring d to be connected with, and on the other side, the axis is Viiattened or formed' polygonal, at 4, to
Aenter the bracket f, so that it will `be held from turning. l
' -The roller-end revolving around the axle 3, is made of tivo parts-the disk h, that sets into a'recess in the `'end of -the Wooden roller-a, and is 'kept from Working" loose by the projecting points 5, and the cap It that sets over the end ofthe roller.
The cam-disk t' is between theseparts h and It, and they arcall held in position, relatively to each other, by the cap k, but the roller and its parts can turn freely upon the axis 3, as the curtain is ldrawn down onagain rolled up by the action of' the spring,
.lhe pawl ois hung within slots or mortises, provided for it in the roller a and disk h and cap k, and acts against the ratchet or cam t', to hold the curtain, or saidpawl isrelieved by the centrifugal action, in allowing the blind to roll up. By my improved construction, the parts can be much more easily made than heretofore, and are less liable to injury in use.
What I claim, and4 desire to secure by Letters Patent is- V 1. The disk h and cap k,'reeeiving between them the cam or ratchet tof the axle 3, as and for the purposes speciii'ed. 0
22 The metal block e, with its projecting points 2, for connecting the inner end of the spring to the roller, as set forth.'
In witness whereof, I have hereunto set mysignature, this. 16th day of' February, A. D. 1869.V
