Reissued Apr. 3, 1934 UNITED STATES PATENT OFFICE SHADE ROLLER Fred J. Burns, Saginaw, Mich., assignor to The Columbia Mills, Saginaw, Mich., a corporation of New York 23 Claims.

This invention relates to shade roller construction, and particularly to the winding mechanism thereof.

One object of the invention is to provide a sim- 5 ple 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. 4 .10 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 roller is assembled, is locked in position.

A further object is to 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. d

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 jars caused by hammer blows when gudgeons are inserted, or when the roller repeatedly falls on the projecting spear. 1

A further object still is to mount and secure the spool bearing on the spool so that it forms a unitary structure therewith, and provide a rugged bearing which will not chatter and which will be noiseless in operation.

The above and other objects will appear as the specification progresses, reference being had to the accompanying drawing in which I have shown the preferred embodiment of my invention, and in which like reference numerals indicate lilre parts throughout the several views thereof .In the drawing Fig. 1 is a part sectional side view of one end of 'a shade roller constructed in accordance with my invention.

Fig. 2 ,isan end view thereof.

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

Fig. 4 is a detail end view illustrating the manner of anchoring the one end of the spring.

Fig. 5 is a view showing the various parts in spaced apart relation.

Fig. -6 is a detail part sectional side view of the spindle and spindle ferrule, the dotted lines showing the position of the prongs before 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 6 saw cut as shown at 9, and the end of the spring is shaped to fit and seat thereon, the opposite end being formed with a loop 10 for a purpose to be later described.

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 a rectangular opening 12 adapted to accommodate the end of the conventional spear 13, which projects into the end of 7 the spindle, the ferrule being provided with spaced apart legs or prongs 14 (shown in dotted lines in Fig. 6) 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 journaled on the ferrule member 11 and is formed with a reduced neck portion 16 which, when assembled, projects into a centrally disposed opening 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 projecting wings 19 for a purpose to be presently described. The outer rim of thespool is turned as shown at 20, and spaced apart ears 21 are punched from the body of the spool and project longitudinally therefrom, said ears being adapted to pierce and be embedded in the roller when the mechanism is assembled.

A ratchet 22 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 section 27 of a size to receive the head of the spear. A ferrule 23 fits over the end of the roller in the usual manner, the inner end being crimped to engage the wood as shown.

In practice the spool 18 is first formed to shape and the pawls 23 are mounted thereon, the spool bearing 15 is then secured to the spool forming a unit therewith, I then take the spear and assemble the hub, ratchet, spool unit, and spindle ferrule thereon, force the spear inwardly to swedge the spear in the ferrule, afterwhich I drive the end of the spear into the spindle and force the prongs 14 of the ferrule into the spindle to rigidly secure it in position. The spring 7 is then placed in position, the one end being an- 5 chored in the saw cut 9, the opposite looped end being threaded behind the wings 19, and the loop will then be locked behind the ears 21,

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 spring assembly from the roller, bend the end of the spring to clear the ears, and it can be easily unwound from the bearing. v

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 i there can be no endwise movement of the ratchet without a corresponding movement of the spool on which the pawls are mounted; the mechanism operates smoothly and easily, is evenly balanced, and will wear for an indefinite length of time. 25 From the foregoing description it will be obvious that I have perfected a very simple, substantial, and economical winding mechanism for shade rollers;
