My invention relates to an improvement in" shade-rollers, the object of the invention be ing to provide improved means for protecting the spring against possibility of tacks being driven into the spring-cavity to interfere with the perfect operation of the spring.

With this object in view the invention consists in certain novel features of construetion and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out'in the claims.

In the accompanying drawings, Figure l is a view in section, illustrating my improvements. the same, and Fig. 3 is a view illustrating a modification.

1 represents an ordinary wooden shaderoller provided in one end with a bore of suitable length to receive a spring 2, secured at one end to a block 8 and at its other end to a rod or shaft 4, mounted to turn in the spring and to wind the spring thereon, the block 3 being secured in the bore by a nail or tack.

driven through the roller and into the block. The shaft 4 is provided with a notched hub 7 for the engagement of dogs 8, pivotally supported by a plate 9, secured to the roller; The operation of these ratchet devices being well known, further description thereof is un- V necessary. This bore in the roller must be sufficiently large to accommodate the spring;

This tube 6 will upset any tacks driven thereagainst, and hence will absolutely overcome the well-known objection to wooden rollers, as above set forth.

A great many other slight changes might be made without departing from my invention, and hence I do not wish to be limited to g the precise construction set forth, but consider myself at liberty to make such other slight changes and alterations as fairly fall within the spirit and scope of my invention. -Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a

wooden shade-roller having a cylindrical cavity in one end, a metal tube secured in said cavity and lining the wall thereof, a spring in said tube and connected at one end therewith, and a shaft entering said spring and having the other end of the latter secured thereto.

12. As a new article of manufacture, a shaderoller having a cavity in one end, a metal tube dried in said cavity and constituting a lining for the latter, a plug secured in said cavity :and entering one end of the metal tube, a spring in the tube secured at one end to said
