SHADE Application led May 3,

To all whom t may concern: e Be it known that I, ANTHONY MoRrnrH a citizen of the United States of America, residing' at Muskegon, in the count-y of Muskegon and State of Michigan, have invented certain new and usetul Improvements in Sha-de Rollers; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

This invention relates to curtain or shade rollers. It is particularly concerned with novel improvements in devices of this character, one of such improvements being directed Ato a means whereby the roller maybe readily and quickly detached from the brackets which are usually made use of t-o carry the `roller and at the same time not have to use the usual bracket with a slot therein cut downwardly from an upper edge of the bracket, the openings in the brackets at both ends of the roller being of a closed type which prevents any disengagement of thevroller from the brackets due to upward movement of the roller with respect to the This is particularly useful in shade rollers used with motor vehicles having ay closed car body, in which, if slotted brackets were used, there would be strong probability of disengagement ot the shade rollers Atrom shocks imparted in travel. A further novel `feature of my invention resides inthe construction of a metal shade roller having a hollow sheet metal body closed at its ends by metal plugs which are soldered in place, on one of which the usual holding dogs or pawls are mounted. It is veryT essential that these dogs or pawls be free to move at all times and to insure this, the plug carrying said pawls is made in a novel manner so that salts used in soldering cannot, under any circumstances, come to the pivotal niountings of the pawls and cause a corrosion which would destroy their free pivotal movement.

The invention by which these and other results not specifically set forth at this point are attained is illustrated in the accompanying drawing, in which,

Fig. 1 is a front eleva-tion of a shade roller made in accordance with my invention.

Fig. 2 is an enlarged vertical longitudinal section taken through the shade roller.

looking in the direction indicated by the arrows, and y Figs. 4 and 5 are end elevations of the constructionsI shown in Fig. 1, illustrating particularly the supporting brackets for the roller.

Like reference characters refer to like parts in the diiiierent figures of the drawing.

The body 1 ot the roller is a tube of metal which is closed at its ends by

plugs

2 and 3, each, preferably being equipped with a flange larger than the body of the roller as shown. The plug 2 at one end ot the roller has a short tube i of metal attached thereto and extends into the roller. A pin 5 passes loosely through the plug 2 and is formed with a head 6 larger in diameter than the opening through the plug, said head entering the tube 4t. Theinner end ot the tube 4l is filled by a plug '7 soldered or otherwise permanently secured in the tube, and a coiled spring 8 is disposed between the head 6 of pin 5 and plug 7, the tendency of which is to keep the pin projected out as :Ear as it will go. However, by pressure against the end of the pin, it may be easily forced inwardly, as is obvious.

The portion 3L of the plug 3 at the opposite end of the roller has an annular groove 9 cut in it entirely around the same. Pawls l() are mounted on pins 11, the ends of which pass into the groove 9 where the same may be conveniently headed over to make a permanent connect-ion. A rod 12 having a iiattened outer end 12a passes loosely through plug 3 and is provided with a slot 13 in position to be engaged by the dogs 10 in the usual manner in shade rollers. rEhe inner end of the rod 12 enters and is connected to a metal tube 14.- which extends to and seats at its inner end in a socket in a wooden piece 15 which is secured to and within the body l o'f the roller. A coiled spring 16 around the tube lliaud attached at one end to the piece 15 serves to connect the rod 12 and. tube 14 at its other end, hold the tube in its socket and act as a torsion spring` to wind the shade on the rollei` in the usual manner with shade rollers.

Brackets 17 and 18 may be used to support the ends of the roller, the bracket 17 having an opening therein to receive the flattened end 12a of the rod 12 and the bracket 1S a circular opening for the entrance ot pin The roller is applied by inserting the end 12a into the opening in bracket 17 and pin 5 is forced inwardly so tliatlthe endV ofthe roller at which it is positioned may be brought into proper position with reference to bracket 18 after which the pin i's released and passes through the opening in" the bracket. rllhe removal of the roller is accomplished by pressing iiron the pin 5 until it is disengaged from the bracket 18.

This construction obviates the necessity of slotting bracket 17 to its outer edge :tor the entrance of the end12a of rod 12, and thus insures against upward movementl of thev end of the roller at ivhich rod 12 is mounted and disengagement of the roller from the brackets `such as may happen, particularly with motor vehicles'- equipped with shade rollers. Atthe same time, the roller is readily removed Whenever desired or put in place between the brackets very readily and quickly.

l l l yThe plugs

2 and 3 are solderedinto the ends of the body 1, in which operation, cer tain l soldering salts `and acids are used. lVithout the groove) on the plug 3,.,s`aid salts ror acids4 'pass along the plug and come veventually to the pa'ivls 10 Where `they are looselymounted onjthe pins 11, ivith` a resultant corrosion which interferes with the free moi/ement of the paivls. The groove brez'iksV the passage of said salts or acids to the paivls and `insures against the possibilityv of such interference with the free moyement of, the paivls. `This is a very necessary 'feature of the invention and the construction, while simple, is particularly practical and efficient. In' addition, the groove allows a ready access to the ends of the pins 11` for securing them in place against disengagement.I l l ,y ,l
