SHADE-ROLLER.
Specification of Letters Patent. Part-elite (l Julie 19, 1917.
Application filed May 13, 1915. Serial No. 27,803. Y
To all whom t may concern: y
Be it known that I, AnnisoN J. SoUDnRs,A a citizen of the Dominion of Canada, and
rollers and hasfor anV object to provide an improved arrangement for normallylock-v ing a roller against movement and allowing a movement of the roller in either direction when given a s udden pull or erk.
A further object in view is to provide one or more balls for locking a shade roller against movement b y the spring thereof.
A still further object in view is to provide a hook or catch for a shade roller which utilizes one or more balls and a guide connected with the roller.
ln the accompanying drawings Figure 1 is a front view of a shade and roller. part being shown in section for bet ter illustrating the construction;
Fig. 2 is a sectional view through Fig. l on line 2 2;
F ig. 3 is a sectional view through Fig. 1 on line 3 3;
Fig. 4 is a sectional view through Fig. 1 approximately on line 4-4;
Fig. 5 is a fragmentary side view of one end of the roller showing a notch for rece'ving the ball case;
Fig. 6 is a fragmentary end view of the spring case, showing the notch for receiving the ball case;
Fig. 7 is a view of the inner end of the spring tube.
Referring to the accompanying drawings by numerals, 1 indicates a shade of any desired kind. adapted to be secured to roller 2 in any suitable manner. Roller 2 is provided with bearing members 8 and 4 fitting into suitable brackets and G, bracket 6 being formed with a suitable opening or socket for receiving the squared end of member4. Member 4 is in effect a shaft and extends into a suitable bore or opening in roller 2 so as to have one end of spring 7 secured thereto while the opposite end extends through a suitable opening in the casing 8.
y Casing 8 may be loosely arranged in roller 2 or secured thereto in any suitable manner. Preferably the rear end ofcasing 8 is provided with a transverse end piece 9, as shown in Figs. l and 7, said end piece acting as a thrust bearing for the shaft 4.
'From Fig. l it will be noted that shaft 4 is also provided with an annular enlargement 10 which loosely bears against the ball casing 11 so that there will be no appreciable longitudinal movement of shaft 4 while a free rotary movement will be allowed. Casingv 11 is provided with an Vaperture throughl which .the rounded portion 4 of shaft 4 passes so that the notches 12 and 13 will be located within the casing 11. The notches 12 and 13 are provided with a rounded bottom portion 14 merging into a comparatively straight side wall 15. This form of socket may be provided in any suitable manner, as for instanceby having a drill forced into the shaft at proper angles producing this form of socket.
The balls 16 and 17 are arranged in casing 11 and are adapted to engage the section 4 of s haft 4 within the notches 12 and 13 for locking the shaft against movement in one direction unless such movement has reached a predetermined speed. These balls are intended to displace or take the place of the ordinary pawls in the shade rollers now commonly in use. By the provision of loose balls in this manner, rivets and other fixed members are dispensed withl so that the sticking or failure of such parts has been eliminated. ln order to prevent the balls from passing out of the casing 11 the same may be provided with a top if desired, though preferably a cap 1S is provided which acts as a cover for casing 1l and also as a cap for the roller as the same overlaps the roller in order that it may be secured to the roller by suitable screws or other fastening means. y
What I claim is:
In a shade roller of the character described, a body provided with a bore in one end, a casing arranged in said bore,r a shaft loosely fitting into said casing, said shaft having a plurality of notches near the outer end, a spring connected at one end with said shaft and at the other end with said casing, said casing at the outer end having a notch and said. body having a notch in alinement with the notchl of the casing, an independent: ballcasing extending through all of said notches, said ball casing surrounding the shaft at the point provided with the notches,
and a. ball. for. each. of the notches arranged in said ball casing, said balls being of suiiicient size to act as wedges and become pinched between the sides of the casing and said shaft when the shaft rotates in a certain direction, said notches being formed in such a inanner that if the shaft is rotating rapidly the balls will not enter said notches.
In testimony .whereof I have signed my name to this specification in the presence of two subscribing witnesses.
