CURTAIN ROLLER.

SPECIFICATION forming part of Letters Patent No. 662,753, dated November 27, 1906.

Application filed August 18, 1900. Serial No. 26,753. (No model.

.To all whom it may concern:

Be it known that I, BENJAMIN FRANKLIN BELL, residing at Nashville, in the county of Davidson and State of Tennessee, have made certain new and useful Improvements in Ourtain-Rollers, of which the following is a specification.

Myinvention is an improvement in curtainrollers, and has for an object to provide an improved construction by which to prevent the overwinding of the shade as well as the drawing of same too far down in the use of the curtain; and the invention consists in certain novel constructions and combinations of parts, as Will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view, and Fig. 2 a longitudinal section partly broken away,0f a curtain-roller provided with myinvention. Fig. 3 isacross-sectional view on about line 3 3 of Fig. 2. Fig. 4c is a detail perspective View of the nut-holding sleeve. Fig. 5 is a detail perspective View of the nut. Fig. 6is a detail perspective viewof the stopring. Fig. 7 is a detail perspective view of the connecting-sleeve; and Fig. 8 is a longitudinal section, partly broken away, showing a somewhat different construction Within the broad principles of my invention. Fig. 9 is a detail cross-section on about line 9 9 of Fig. 2. Figs. 10, 11, and 12 are cross-sections on about lines 10 1O, 11 11, and 12 12 of Fig. 8; and Fig. 13 is a plan viewof the construction shown in Fig. 8.

The roller A may in general respects be of the ordinary construction, and the curtain or shade B may be secured thereto in any wellknown or desired manner. The roller A is provided in one end with a longitudinal bore 0, in the inner end of which is secured a block D, to which is fixed the screw E, which extends, preferably, to a point beyond the outer end of the roller, as shown in Fig. 2, and is provided at such end with a tenon c, which is adapted to fit in the bracket F, as shown in Figs. 1 and 2.

Upon the outer end of the rollerA, I secure a casing G, in tubular form, having its end plate G perforated at g to form a bearing for the nut-holding sleeve, the opposite end of the casing G being held upon the rollerAby screws, as shown, or in other suitable manner. The casing G is provided at g with slots in which operate the lugs of the stop-ring, as shown in Fig. 2.

An annular cap-plate H is secured upon the end of the roller A within the casing G and supports the pawls I, which maybe of the ordinary construction and operate at their points within the slot 7' of the nut-holding sleeve J, as shown in Fig. 3. The cap-plate H also supports a pin or stud K, preferably forming the extensions of one of the pivots of the pawl andarranged to strike against the radially-projecting portion L of the nut L to stop the downward movement of the curtain or shade in the operation of the device.

The nut-holding sleeve J is shown in detail in Fig. 4E and is supported, as best shown in Fig. 2, at its outer end in the bearing g of the end plate G of the casing G and at its inner end in a bearing h in the cap-plate H.

The sleeve J extends inwardly beyond the cap-plate H and supports on such extension the connecting-sleeve M, which is provided at its inner end with returned portions, forming rings M to hold the outerend of the spring N, and also provided with inwardly-projecting lugs M which enter openings M in the sleeve J,and thus secure the connecting-sleeve upon the nut-holding sleeve, as will be understood from Figs. 2, 4, and 7. end of the spring N is secured to the block D, as shown in Fig. 2.

The sleeve J has a longitudinal slot j and is provided at its outer end with the inwardlyturned perforated ears J and J which form bearings for the outer end of the screw-shaft E, and it also has at its outer end the outwardly-turned arms J whose ends J 4 are arranged to engage the bracket F and prevent the rotation of the sleeve J in either direction.

The nut L fits within the sleeve J and is threaded on the screw E so the turning of the latter will feed the nut back and forth in the sleeve J, and such nut is provided with a radially-projecting arm or portion L, which projects through the slot j beyond the sleeve J in position for engagement by the pin K when such arm L is adjusted into the path of the The opposite pin K in the operation of the invention. The pin K, as before suggested, stops the movement of the roller in one direction. To stop the movement of the roller in the opposite direction, which in the construction shown is the upward movement of the shade to prevent overwinding, Iprovide the stop-ring 0. (Shown in detail in Fig. 6.) This ring 0'' is provided with the lugs O, which project through the slots g in the casingGrand operate to hold the ring 0 to the casing and yet permit it to be adjusted in the casing in the direction of length of the latter. The ring 0 also has an inwardly-projecting lug or portion 0 which projects with such relation to the lug L of the nut L that it will strike suchlug when the latter is moved into the path of the projection O by the operation of the screw E at the upper end or part of the upward movement of the curtain. It will be noticed that in the operation of my invention the curtain is-stopped by the striking of some portion attached to the revolving roller against a portion of the nut as the stop portion on the roller revolves. By this means I avoid anyjamming of the nut upon the threads of the shaft, so the nut will not become bound upon the shaft or screw in such manner as to prevent or hinder the raising or lowering oi'the curtain from its stopped position.

By arranging the stop-ring O for adjustment within the casing G such ring may be set to stop the roller at different points, so the height to which the curtain can be raised may be conveniently regulated.

Manifestly the invention can be used as a combination with the spring shade-roller, as shown in Fig. 2 and before described, or the improvements can be attached to the opposite end of the roller from that containing the spring and be used as a separate attachment.

In Figs. 8 and 10 to 13, inclusive, I showa construction which can be used on the largest or smallest sizes of rollers and which, like that shown in Fig. 2, can be used as a-combination with oron the opposite end of the roller from the roller-actuating spring.

In the construction shown in Fig. 2 the stop-ring O is movable longitudinally in the casing Gand is held from turning. In Fig. 8 the casing 1 is provided with

longitudinal slots

2 and 3, the slot 2 being-serrated at one edge and having at its other edge an inturned fiange'i. The flange a is engaged by the slotted end 5 of the nut 6, which is threaded on the screw-shank 7, so said nut 6 will be caused to travel in and out as the roller is'turned in opposite directions on said screw-shank.

The stop 9 in Fig. 8 is also movable within the casing and preferably has a port-ion operating in the longitudinal slot of such casing, as is also the case with the construction shown in Fig. 2. Thestop 9 includes a center block 10, keyed on and movable along the'screw 7, and has a circumferential groove 11, in=which is held the stop-frame 12, having

theradiallyopposite projections

13 and 14, operating in any desired point.

the

slots

2 and 3, the projection 13 having two arms which spring apart and cause one of them to engage in the serrations at one side of slot 2, as will be understood from Figs. 8, 12, and 13. It will be noticed that the frame 12 is so held in the groove 11 of the block 10 that it can turn on said block as on an axis. By this construction the stop 9 can be adjusted within the casing to stop the roller at In both constructions described the nut will be fed longitudinally along the screw shaft-in oneinstance, Fig. 1, by the turning of the shaftthrough its connection with the roller and in the other case, Fig. 8, by the turning of the nut on the screw-shaft, so the raising and lowering of the roller will adjust the nut to position toengage the projections whiclr are arranged in the patlrof the un t to stop the same",- anjd thus stop the tn ruling of the roller.

Having thus described my in vention, what I claim as new, and desire to secure by Letters Patent, is
