SHADE ROLLER COMPANY,' OF SAGINAW, MICHIGAN;
BEARING FOR SHADE-ROLLERS.
srEcrFIoArIon forming part of Letters Patent No. 734,530, dated July 28, 1903. Application filed December 24, 1902. Serial No. 136,43 9. (No model.)
To all whom it may concern:
Be it known that I, CLAUDE FLAGLER, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan,
have invented certain new and useful Improvements in Bearings for Shade-Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the to art to which it appertains to make and use the same.
This is a bear-ing for spring-actuated shaderollers, and relates more particularly to theconstruction of the pintle or spear and to the IS bearing of the roller-cap.
The objects of my invention are to provide a true continuous cylindrical bearing for the roller-cap as near as possible to the bracket which is the point of support, to insure 2o smooth and frictionless running and to prevent binding, to give as large a diameter as possible to the ratchet, thus permitting the use of short pawls, and also close the front opening to exclude dirt and shade ravelings from the Working parts.
My invention consists in the means where-' by these objects are attained and is illus trated in the accompanying drawings, in which- Figure 1. is a section of the end of a roller using my invention. Fig. 2 is a side view of the pintle, commonly termed in the trade the spear. Fig. 3 is an end view of the spear.
Fig. 4 is atop view of the cover-plate. Fig.
5 is an enlarged section on'the line :ncoof .Fig. 4. Fig. 6 is a bottom view of the pawlplate and cover-plate assembled. Fig. 7 is an elevation, partly insection, of the end of a roller using my invention supported in a 0 bracket.
-My invention is particularly applicable to ,the construction shown in Patent No. 713,644, cap for shade-rollers, issued to William D. Janes November 18, 1902.
The supporting-spear 1 in my invention is fixed in the end of the spindle 2 within the roller 3 and has a hole 1, in which one end of the actuating-spring 4 is secured. The outer end 1 of the spear is flatted to support the where the spear receives the weight of the Patented July 28,1903.
roller and the point where the bracket supports it is reduced to the minimum amount. Back of the journal is a shoulder 1, larger than the journal, which prevents the spear playing lengthwise through the cover-plate and also provides a place for the notches 1 independent of the bearing. close the opening in the bushing 5 from the inside, and so excludes dirt and ravelings. The hole 6 in the pawl-plate 7 is larger than the shoulder to allow the spear to be entered It also serves tointo the cap through the pawl-plate, and the hole being larger than the shoulder there is no chance for the shoulder to touch or bind against the pawl-plate, and itis left entirely free to operate in the bushing provided for that purpose in the cover-plate. porting-bearing in the cover-plate is as near as possible to the supporting-bracket, thereby preventing the spearfrom binding or get-' ting out of line.
In this improved construction the shoulder 1 may be of large diameter, thereby reducing the strain on the pawls 7 and permitting the use of shorter pawls, which adds strength and insures smooth running.
What I claim as my invention, and desire to secure by Letters Patent, is as follows:
1. A hearing for shade-rollers comprising The supin combination a cap consisting in an inner pawl-plate with a large central opening, an outer cover-plate with a smaller central opening having a suitable bearing-surface, and pawls pivotally secured between the plates; together with a fixed supporting-spear on which the cap revolves, said spear having a continuous cylindrical journal which is a neat turning fit inthe opening in the cover-plate;
50 roller withoutturning in the slotted bracket a shoulder back of the journal larger than oo the journal but smaller than the opening in the pawl-plate, and notches in said shoulder to engage the pawls.
2. As a bearing for shade-rollers the combination with a cap comprising a cover-plate, a pawl-plate having a central opening and pawls secured between said plates; of a bushing secured in the cover-plate; and a spear having a continuous journal-bearing in the bushing, a shoulder back of the journal prel venting outward movement of the spear 1 through the cover-plate, and notches in the shoulder adapted to engage the pawls, said centralopening in the pawl-platebeing of largerdiameterthanthediameteroftheshoul- I5 der; for the purposes set forth.
In testimony whereof I afiiX my signature in presence of two Witnesses.
CLAUDE FLAGLER.
