SHADE-ROLLER.

SPECIFICATION formingpart of Letters Patent N o. 704,738, dated July 15, 1902. Application filed February 26, 1900. Serial No. 6,543. (No model.)

To all whom t may cou/cern:

Be it known that I, OLIVER M. EDWARDS,

My invention relates to that class of shade-I rollers which are movable from and replacefY able in their brackets with the usual facility that this is done in ordinary shade-rollers and in which a pawl or dog is employed for purposes of adjusting the stress or tensin of the springs while the rollers are wholly or partially removed Vfrom their supportingbrackets and is inoperative during the normal use of the rollers. Shade-rollers of this class (which are many times known as bottom or single-notch spring-rollers) as usually used have one or tWo pawls or dogs attached to the body portion of the roller, so as to move relatively thereto by gravity, and only one point of engagement with the spindle. In use the spindle is placed in its bracket, so that this point of engagement, usually a notch in a disk on the spindle, is beneath the spindle, and gravity in this case causes the pawl or dog, as the Vunder side of the spindle is approached inthe revolution of the body portion of the roller around it, to fall away from the spindle and its notch or point of engagement and prevent the engagement of the pawl therewith. Consequently the pawl o'r pawls are inoperative in the normal use of the roller. The stress or tension of the rollers of this class is usually adjusted before the rollers are mounted in their brackets, but after the material to be wound thereon is se'- cured to the rollers and while both spindle and body portion of the roller are free to rotate. The material to be wound upon the roller is,as usual with these single-notch rollers, of such dimensions relatively to the roller and is so secured thereto that the pawl or dog is readily accessible when it is desired to lii't the dog against the action of gravity and cause it to engage with the spindle. To adjust the stress of the spring, the roller is held so that when the dog or pawl is opposite the notch in the spindle it will fall into it,and as soon as this occurs the spindle and body por- Vvtion of the roller are held in Iixed relation to each other, so that the roller can be mounted in its bracket, as explained. 1When this is done, the body portion is turned a little to relieve the frictional contact of the dog and notch,when thel dog is free to fall by gravity, and it cannot engage with the spindle again until forced upward against gravity and made to enter the notch. Spring-rollers of this class are thus used when the thing, whatever it may be, is held in desired positions by means outside of the rollers themselves-as, for instance, the automatic raising of window-sashes, whereA the sash is held in the desired positions by devices acting directly upon the sash. lf rollers of this class be placed in brackets, with the notch or point of engagement for the dog uppermost or above the spindle, each time a dog or pawlpasses such notch or point of engagement it can fall into the notch and engage therewith, if the movement of the dog and body portion of the roller be slow enough to permit of its doing so. Many times rollers of this class have been'placed in their brackets with the notch of the spindle uppermost, when the reverse should have been the case, and quite serious accidents have occurred by reason 0i' Windowsashes falling from this cause.

The object of this invention is to obviate this difiiculty by dispensing with the use of gravity o r other automatically-acting pawls or dogs in this class of rollers and providing other means by which the barrel and spindle may be held or locked in fixed relations to each other for the purpose of adjusting the tension of their springs and yet have all of the convenience of removal and replacement of such rollers in their brackets and of adjustment of the stress or tension of their springs now had in the single-notch roller hereinbefore described and also to provide a construction which is simple and may be cheap to manufacture, convenient to use, and without liability oi." being wrongly placed in its brackets, and'thereby causing accidents;

and it consists in combining with the barrel and spindle of spring-rollers of fixed abutting surfaces, the surface or surfaces on the barrel being adapted to move past the snrface or surfaces on the spindle, the surface IOO or surfaces on the spindle being arranged with a portion of such surface or surfaces in a circle of greater diameter than the body of the spindle, whereby means adapted to engage with the abutting surfaces may be employed solely for locking the spindle to the roller and Vwhich are normally free from a locking position between the abutting surfaces, but are manually movable into such klocking position; and myinvention also consists in certain other novel and useful combinations of parts, all of which will be hereinafter fully described, and pointed out in the claims.

Like letters of reference, wherever they occur, indicate corresponding parts in all of the figures.

Figs. 2.n and 2b show modifications of the construction seen in Figs. l and 2. Fig. 3 is an end elevation of a spring-roller, illustrating a modified construction of myimprovement applied thereto. Fig. -1 is a longitudinal sectional view of a portion of the roller seen in Fig. 3. Figs. 5, 6, 8, and 9 are end elevations of spring-rollers having modified constructions of my improvement applied thereto. Fig. 7 is a longitudinal sectional View of the construction seen in Fig. (i. Fig. S is a longitudinal section of a modification shown in Fig. 8.

In Figs. l and 2, A is the barrel, and it is formed, as is usual with this class of rollers, of sheet metal, cylindrical in form, and provided with the usual slot (not shown) to receive the end of the shade or other material lo be secured thereto and the rod which secures such end to the roller. The barrel A is supplied with the usual heads or end pieces, one of which, B, receives the spindle C, the spindle passingloosely through the head B in the usual manner, so that a portion of it is within the barrel A and a portion extending beyond it, the latter portion being attened on opposite sides, adapting it to be vreceived by the usual slotted bracket and held therein against turning by the slot in the bracket engaging with the flattened sides of the extending end of the spindle. One end of the spring D is connected with the barrel A, and the other end is connected with the spindle C in the usual manner, and as the barrel is turned in the direction ot' the arrow on Fig. vl, the spindle remaining stationary, the spring is unwound or uncoiled, and the reverse movement of the barrel relatively to the spindle winds up the spring D and puts it under stress or tension to enable the roller to do its work, all as is usual with this class of rollers. The barrel A at its end opposite the extending end of the spindle is provided with the usual journal or bearing, which is received in the usual form of bracket used with this class of rollers. The head B is provided with a fixed abutting surface b, which may be formed integral with the head B, as shown, or otherwise, as the judgment of the constructor dictates. The spindle C is provided with a disk C', which disk, as shown, is provided with two fixed abutting surfaces c c', formed therein, as desired, the surfaces c c' on disk C being arranged, preferably, as shown, wholly in a circle of greater diameter than the body of the spindle-as, for instance, taking the body at a point between the end of the spring which is secured to the spindle and where the spindle is enlarged to pass through the head B of the barrel; or the surface c or c may be otherwise arranged so long as the portion farthest from the axial line of the roller is arranged in a circle of greater diameter than the body of the spindle, so that such portion may serve to extend theleverage of the abutting surface to a point beyond the circumference of the body of the spindle, which is usually the smallest portion thereof. These surfaces c and c are preferably formed in the same radial plane with the surface b, and they are preferably made so as to pass in close proximity one with ,the other, but without contact therewith. This construction and arrangement of abutting ,surfaces on the spindle permits of two, three, or more of such surfaces being formed thereon without unduly weakening the spindle at what is usually its weakest point and also gives to the abutting surface au increased leverage, and vconsequently a smaller and weaker device may be manually inserted between the abutting surfaces on the barrel and spindle than otherwise would be the case, the action of the surfaces on the device being of the charactery of a shearing action and not that of simply a bending one.

In order to adjust the stress or tension of the spring D, the barrel A, before the roller is placed in its brackets, is turned relatively tothe spindle C in a direction opposite to that indicated by the arrow on Fig. l until the desired stress or tension is obtained, and then a pin x may be manually inserted between the abutting surface band abutting surface c, (or I) and c,) as seen, andthe stress or tension of the spring D allowed to force the lower portion of the pin a; against surface c by contact of surface b with the middle portion of pin .r, when the barrel A and spindle C will be temporarily held in fixed relations to each other, and in this condition the roller can be placed in its supporting-brackets, as usual. To release the barrel and spindle from such fixed relations, it is only necessary to move the barrel in a direction to wind up the spring and remove the pin.

To remove the roller from its bracket, move the barrel against the stress ofl the spring until the pin a: or a similar acting device can be manually inserted or moved in between the surface h and either c or c, as the case may be,

IOC

and permit the barrel to force the pin in contact with the surface c or c', when the barrel and spindle will again be temporarily'held in fixed relations to each other and the roller can be removed from its brackets and any desired work be done thereon and the roller returned into position for doing its normal work. The pin forms means which is Inannally movable into and out of locking position between the abutting surfaces h and cl or h and c to temporarily hold or lock the barrel and spindle in fixed or locked relation to each other. The pin is independent of the roller, being unattached thereto, but is manually movable into position to lock the spindle to the roller whenever it is desired to adjust the tension of the spring.

Instead of the abutting surfaces being arranged in the same radial plane, as seen in Figs. l, 2, 5, 6, and 7, they may be arranged in dierent radial' planes, as seen in Figs. 3 and 4, whereinA abutting surfaces, four` in number, 5,172, b3, and b4, are secured to the head B in any desired manner, all in one radial plane, and four abutting surfaces c2, c3, c4, and c5, are formed on the spindle C2, as shown, and arranged in another radial plane and preferably to pass in close proximity to the surfaces' b, b2, b3, and b4, but so that one series of surfaces may pass the other without contact therewith. In this case the pin may be interposed between any one of one series 'and any one of the other in a direction parallel with the ,axis of rotation of the roller, and it is shown as beinginterposed between the surface b and cr-*but it may be otherwiseinserted,ifdesired-as,forinstance, in the direction shown in Figs. land 2. In Figs. 3 and 4, A' is the barrel; B,the head; C2', the spindle, and D' the spring.

mode of operation are the same as in case of the construction seen in Figs. l and 2.

Instead of having one abutting surface b on the head B and two, c c', on the spindle C,

as shown in Figs. 1 and 2, there maybe two such, b5 and b, onthe head B2 and one, c6,

on the spindle C4, if desired, as seen in Fig. 5, the construction of head and spindle there shown otherwise being the same as in Figs. l and 2. In this case the pin'm2 or other 'device adapted to serve a similar purpose may be manually inserted in a direction parallel with the axis of rotation of the roller, if desired, as indicated in dotted lines in Fig. 5. Also the abutting surfaces may be formed on head B3, as shown in Figs. 6 and 7, and of any desired number-as, for instance, the four, bl, t8, b9, and b1, seen in Fig. 6. In

this case a hole is drilled from the exterior of nine of these notches, c7 cs, 095cm, c, cl2, cl3,

Otherwisel than as just explained the construction andA 014,'and 015, each one of which forms an abutting surface on thefspindle, against which the lower end of pin m3 may abutwhen placed in any one ofthe four holes through which the lower portion of such pin may be thrust. In Figs. 6 and 7, A3 is the barrel; B13, the head; C, the spindle; C?, the disk thereon, and D3 the spring. Otherwise than as above the construction and mode of operation are the same, as in case of the construction seen in Figs. l and 2. j A

More than one abutting surface formed on the barrel-head is advantageous, because it provides for the interposition of the pinl or similar acting device from more than one direction relativelyto the. axis of rotation of the roller, when it is in the bracket, and the roller does not have to be turned so far against the stress of the spring tolreach a given abutting surface on the spindle. Also more than one abutting surface on the spindle is advantageous, because, with two of .such surfaces,

as seen in Fig. l, the roller can be placed in its bracket with the spindle either side up and the pin inserted from below the spindle or above it, as desired; if there be more than two, as seen in Figs. 3 and 6, then `the pin can be inserted at different points in the rotation of the barrel relatively to the spindle, as the circumstances may make it most convenient to do so, also it'permits of a closerv adjustment of the stress or tension of the spring, as well as of placing the roller in its brackets in position for the removal of the pin, if that be the means employed are manually movableinto locking position between e the abutting surfaces, or yit' other means be employed, then to give ready access tothe portion of such means, which means are manually movable'into locking position between the abutting surfaces when the roller is to be removed from its brackets for'any reason.

Instead of the pin shown the pawls y y and IOO IIO

of which is manually movable in to position l to engage with the abutting surfaces on'the head BL1 and spindle C8, as seen Vinf/ Fig. S. Abutting surfaccsc, 61,7, c18.fand amare Vformed on disk C9 of spindle 08, as seen, and

abutting surfaces bu. andl` are formed on the head B4, the latter surfaces being round and in the form of pivots on which the pawl y or y turns and against which a portion of such pawl abuts. Yfheu it is brought into the position, pawl y is'seen in dotted lines in Fig.' 8, where such portion also abuts against the surface c1S onthe spindle. The pawls or dogs y q2 are manuallymovable from the positions shown in Figs. 8 and 9 into locking positions between the abutting surfaces on the barrels and spindlesagainst the stress or tension of the springs w wz, which serves to normally hold the pawls or dogs free from the locking position between the abutting surfaces.

ed in their brackets or removed therefrom These-.dogs or pawls are thus man- Y ually movable whether therollers are 1nou nt,v

and without disturbing the material wound upon the rollers; As shown in Fig.`8, the disk C9, in'which the abutting surfaces 015,

c, 018, and 019 are formed, is arranged in the same-radial plane with the abuttingsurfaces b and 1912 as is the case in Figs. l and 2, as this arrangement requires less space at the end of the roller for the adjusting and holding devices thereof; but they could be arranged in different planes, as indicated in Fig. 8-, wherein the pawl g4, partly broken away to show surface Z915, and a portion of the disk C12 are seen in side elevation, the free end of pawl y extending from one radial plane to the other, as seen, so that such free end engages with abutting surface in disk C12. Inotherrespectstheconstruction shown is the same as in Fig. 8.

If for any reason it should be thought that by handling of the roller after the stress or tension of its spring had been `adjusted and before it is placed in its supporting-brackets the pawl y or y might by reason of the stress of spring w or 'w' move out from the position between theabutting surfaces, (seen in dotted lines in Fig. 8,) one ofthe abutting surfaces may be undercut, las seen in Fig. 9- that is, the surfaces on the barrel or on the spindle may be cut, so that when the kpawl y2 or y3 is once in full engagement with its abutting surface, as seen in dotted lines in Fig. 9, the barrel A5 will have to move bodily relatively to the spindle C10 against the stress or tension of the spring D5 (not shown) spring cu2 or rws would naturally be made so that it could not overcome the stress or tension of spring D5 when the roller was in the brackets and doing its normal work. Consequently pawl y2 or ya when once it has engaged with its surface it cannot become disengaged until outside force is applied to the barrel or spindle,or both,and move one relatively to the other against the stressof spring D5 andpermit spring w2 or w3 to do its work. In Fig. 9, A5 is the barrel; B5, the head; C10, the spindle, and Cl1 the disk thereon; Z914, abutting surface on head B5, and C20 abutting surface on disk C11, and 1112 spring for pawl y2. The same result is accomplished by constructing the abutting surfaces c and c' and the pin a; (seen in Figs. 1 and 2) as shown in Fig. 25 or Fig. 2b, the barrel being cut away, if desired, to permit of the pin being inserted in a radial direction, the pin m4 or 005 in `each case being preferably made rectangular in cross-section. Otherwise than as just explained the constructions shown in Figs. 25L and 2b are the same as that found in Figs. l and 2, and the mode of operation is also th same. In Fig. 25 portions of the roller are broken away, as seen. In Fig. 25, A6 is thepbarrel; B5, the head thereof; C15, the spindle, and C14 the disk on the same. In Fig. 2"', A7 is the barrel; B7, the head; C15, the Spindle, and C15 the disk on the spindle. 2 To adj ust the stress or teSlOgn of the spring in the construction shown m Figs. S and 9,

aypin 'La in the hand of the operator may be made to engage with pawl 'y' through an opening 'u' in the barrel A4, if desired, by means of which the free end of the pawl is manually moved toward disk C9 against the stress of spring w' until the pawl engages with one of the abutting surfaces formed on such disk, as seen in dotted lines in Fig. 8, where it is `shown in engagement with surface 018, the

barrel and spindle being manipulated as before to obtain the desired stress or tension of the spring. After the roller is placed in its supporting-brackets it is only necessary to move the barrel against the stress of the spring'a short distance, when spring w' is free to move pawl y into the position seen in full lines in Figs. 8 and 9, when thebarrel and spindle are no longer held in fixed relations or locked to each other and the roller is ready to perform its normal Work in connection with a window shade, sash, or other lthing which it is adapted to support and move from one position to another, it being immaterial for the purposes of my improvements what particular use the shade-rollers be put to so long as they are adapted for the work to be done; but they are especially useful in supporting and moving the window-sash of railway-cars. l

It will be observed that whether the pin an, however formed, or the pawl or dog y be used each forms means which are manually movable, irrespective of the position of the spindle in its bracket, into locking position between the abutting surfaces formed on the barreliand spindle, respectively,which means are normally free from such locking position. In each case such means become operative to hold the barrel and spindle in fixed relations to each other when a portion of such means is moved into position between such abutting surfaces, and the stress or tension of the spring of the roller is suicient to hold such portion in such position.

i Various forms or shapes of devices to be manually moved into locking positions between the abutting surfaces in different ways and from diierent directions have been shown and described, and hence it is manifest that the shape, the way, or the direction the means or device is manually moved or inserted into locking position is immaterial so long as some vmeans or device is manually moved into locking position between the abutting surfaces,ir respective of the position of the spindle in its bracket, so as to serve as a stop or abutment for such surfaces and temporarily lock the spindle and-barrel together,whether the roller is mounted in its brackets or removed therefrom, and such means or device is normally free from such locking position. As shown in Figs. l to 7, the barrel, spindle, and abutting surfaces are so constructed and arranged relatively to each other that the manually movable or insertible means or device is independent of the roller-that is, not attached thereto-and such means or device is IOO IIO

employed solely for locking the spindle to the roller, and it is bodily removed from the roller before such roller can begin to serve its main purpose, and Ahence it is normally free from 5 its locking position between the abutting-surfaces. In Figs. 8, S, and 9 the parts are so constructed and arranged relatively to each other that the manually movable or insertible means or device is pivoted tothe barrelhead; but in each case it is held out from the locking position between the abutting surfaces by the stress or tension of the spring bearing on such device or means, and hence it is normally free from such locking position, and it is also manually movableinto such position irrespective of the position of the spindle in its bracket or whether the roller is mounted in its brackets or removed therefrom;

Itis to be observed that in each form or embodiment of my improvement the use of a gravity or other automatically operatingpawl or dog is dispensed with and only a manually.- movable part or device is employed, which is manually movable into locking position irrespective of the position of the spindle in its bracket or whether'the' roller is mounted in its brackets or removed therefrom, which movable part is normally free from such locking position, and it is employed solely for locking the spindle tothe-roller.

In each construction herein shown and described, which is the preferred form, the abutting surface or surfaces with which the spindie is provided are formed on a disk or enlargement found on the body of the spindle, and as a result such surface or surfaces are arranged in a circle of greater diameter than the body of the spindle. Thev body of the spindle is usually, as shown, of the smallest diameter of any of its parts. Such surface or surfaces may be arranged as desired, so long as the portion farthest from the axial line of the roller is arranged-in a circle of greater diameter than the body of the spindle, so that such portion'xnay serve to extend the leverage of the abutting surface beyond the circumference of the body of the spindle, and thus may aid in opposing or overcoming the stress or tension of the spring when the spindle and barrel are locked together. This arrangement of the abutting surface or surfaces of the spindle with those portions farthest from the axial line ofthe roller in a circle of greater diameter than that described by such body not only increases the leverage of suchV surface or surfaces, but'also permits, if desired, of the manual movement or insertion of the means or devices into locking position from dilfercnt directions, as shown, Vwhich is very advantageous in certain uses to which rollers of the general form of singlenotch rollers are put.

The several constructions and arrangements of abutting surfaces and manuallymovable means or'devices herein shown and described are the first, so far as I know, in

which the rollers can be placed in their brackets or mountings and removed therefrom with the ease and convenience of the single-notch rollers heretofore described and at the same time without danger of causing accidents by wrongly placing them in working position. Also, so far as I know, the present constructions are the first to retain all of the advantages, including cheapness ofconstruction, of any of the prior constructions without an y of the disadvantages pertaining thereto. No matter how the spindle of any one of these constructions may be placed in its bracket or mounting when the manually-movable means or device is removed from its locking position between the abutting surfaces there is nothing which can in the normal condition of the roller lock orhold the barrel and spindle together, and thereby cause-the accidental fall of a window-sash or similar object connected to the roller and injury to persons using the window containing such sash.

Of course there isthe possibility that springs w, w', and to2 (seen in Figs. 8 and 9)'may break and'permit the pawls or dogs to move into position between the abutting surfaces therein shown; but the roller then would not be in a normal condition. It is because of this possibility, among other things, that the constructions shown in Figs. l to 7, inclusive, are preferred over those showniu Figs. 8 and 9.

I have herein shown and described differing embodiments of my improvement, and it will be manifest to those skilled in this art that other forms or embodiments than those shown may be employed and yet embody in substance one or more of the combinations of elements or devices hereinaftery recited.
