i SAGINAW, MICHIGAN, Av CORPORATION OF NEW YORK SHADE ROLLER VApplication filed August 25, 1931. Serial No. 559,227.

This invention relates toV shade roller construction, andrparticularly to the winding mechanism thereof. Y

One object of the invention is to provide a simple and substantial winding mechanism, made up of a minimum number of parts, which will not get out of-order; which will be cheap to manufacture, and which can be readily installed and assembled.

Another object is to provide new and novel means for anchoring the outer end-of the spring, so that it'can be readily positioned or removed, and which when the rollery is assembled, is locked in position.`

` A further object is to4 provide a large .and

rugged self centering bearing of simple construction, which will run accurate and true, and which will not become sloppy with long use. v

A still further object is to `provide a winding mechanism so constructed and :assembled, that all parts remain in their true assembled working relation, regardless of severe blows or ars caused by hammer blows when gudgeons. are inserted, or when the roller repeatedly falls on the projecting spear.

` `The above Vand other objects will appear as the specification progresses, reference being had to the accompanying drawing in which I have shown the preferred embodi- V ment of my invention, and in which like ref- @rence numerals indicatelike parts throughvout the several nviews thereof.

In the drawing: i j j i Fig. 1 is a part sectional side view of one end of a shade roller constructedin accordance with my invention. A

Fig. 2 is an end view thereof.

Fig. 3 is a longitudinal .sectional view through the winding mechanism.

Fig. 6" is a detail'part sectional side Yview of the spindle and spindle ferrule, the dotted lines showing the position of the `prongs be- Yfore being forced into the spindle. V

Fig. 7 is an end view of the spindle ferrule.

Referring now to the drawing in which I have shown the preferred embodiment of my invention, the numeral 5 indicates the body of the roller which can be of any suitable material, wood being most common in use, this is centrally bored as shown at 6, and is adapted to accommodate the conventional spring and spindle, 7 and 8 respectively, the inner end of the spindle having a saw cut as shown at 9, and the end of the spring is shaped to lit and seat thereon, the opposite end being formed with a loop 10 for a purpose to be later described. Y

A ferrule member 11 fits over the outer end of the spindle, the head being reduced and projecting slightly beyond the end thereof, said head being formed with arectangular opening 12 adapted to accommodate the end of the conventional spear 13,which projects into the end of the spindle, the ferrule being provided with spaced apart legs or prongs 14 (shown in dotted lines in Fig. 7)v and is adapted, when the ferrule is placed in position, to be forced into the spindle to hold the ferrule tightly in place.

A spool bearing 15 is ournaled on the ferrule member 11 and is formed with a reduced neck portion 16 which, when assembled, projects into a centrally disposed opening 17 provided in a spool 18 and is solidly crimped over the edge thereof forming a solid unit therewith, the inner end of said spool bearing fitting over the ferrule member 11 and is formed with spaced apart laterally project- 'ing wings 19 for a purpose to be presently ears being adapted to pierce and be embedded in the roller when the mechanism is assembled.

A ratchet (not shown) is mounted on the spear directly adjacent the turned end of the spool bearing and the usual diametrically opposite pawls' (not shown) are .pivotally mounted on the spool by means of rivets 24, and are adapted to engage the ratchet in the usual manner, a hub 25 being mounted on the spear, and is interposed between the ratchet and the shoulder 26 of said spear, said hub having a centrally disposed dished center tion 27 of a size to receive the head of the spear. A errule 28 fits over the end of the roller in the usual manner, the inner end being crimped to engage the Wood as shown.

ln practice the spool 18 is iirst formed to shape and the pawls 23 are mounted thereon, vthe spool bearing 15 is then secured to the spool forming a unit therewith, l then take the spear and assemble the hub, ratchet, spool, and spindle ferrule thereon, and then force the end of the spear into `the spindle, sWedging the spear in the 'ferrule The spring 7 is then placed in position, the one end being anchored inthe saw cut 9, the opposite looped end being threaded behind the Wings 19, and the loop l() will then be locked behind the ears 2l, and as the Winding unit is mounted in the bore of the roller, these ears together With the looped end of the spring will pierce the Wood and lock the end of the spring securely in position. To detach, it is merely necessary to remove the roller, bend the end of the spring to clear the ears, and it can be easily unwound from the bearing.

I Wish to direct particular attention to the fact that the general assembly absolutely eliminates the possibility of the mechanism becoming sloppy so that the pawls do not engage at all times; there can be no endwise movement of the ratchet Without a correspending movement of the spool on which the paivls are mounted; the mechanism operates smoothly and easily, is evenly balanced, and Will Wear for an indefinite length of time.

From the foregoing description it Will'be obvious that I have perfected a very simple, substantial, and economical Winding mechanism for shade rollers.

lVhat I claim is l. A shade roller comprising a. body, a spindle extending thereinto, a spool mounted on said spindle and secured to said body, and a spring anchored to one end of the spindle, the opposite end of said spring engaging said spool and being embedded and anchored in the end of the roller body when the roller is assembled.

2. A shade roller comprising a body, a spindle extending into said body, a spool rotatably mounted thereon, a spool bearing secured to the spool, a spring mounted on the spindle and anchored to one end thereof, the opposite end being threaded on the spool bearing, and embedded and anchored in the end of the roller body when the roller is assembled.

3. A shade roller comprising a body, a spindle yextending thereinto, a spool mounted 4on the spindle, a spool bearing rigidly secured thereto and havingr Wings projecting` laterally therefrom, a spring mounted on the spindle, one end being anchored thereto, the opposite end being threaded behind said Wings, and means on the spool for preventing the unwinding of the threaded end of said spring during the assembling of the roller.

4. A shade roller comprising a body, a spindle mounted therein and provided with a ferrule on one end thereof, a spool having a spool bearing rigidly secured thereto and mounted on said spindle, laterally projecting wings on said bearings, a spring mounted on the spindle and anchored to one end thereof, the opposite end being looped and threaded behind said Wings, and means on the spool for anchoring the threaded end of the spring as the roller is being assembled.

5. A shade roller comprising a body, a spindle mounted therein, a ferrule on the end of the spindle, a spool, a spool bearing secured thereto and formed With laterally pro` jecting Wings, a. spring mounted on the spindle and anchored to one end thereof, the opposite end being looped and threaded behind the Wings of the spool bearing, and ears on the spool for engaging the looped end of the spring and piercing the body of the roller when said roller is assembled.
