NT OFFICE ASSIGNOR TO J". G. WILSON CORPORA- TION, OF NEW YORK, N. Y., A CORPORATION OF VIRGINIA ROLLING-DOOR-CURTAIN MOUNTING Application fi1ed.0ctober 19, 1928. Serial No. 313,426.

This invention relates to a rolling or coiling door curtain mounting, and more particularly to the drum member to which the As heretofore commonly constructed apparatus of the type to which the invention particularly relates is made to include a suitably journaled shaft, preferably a tubular shaft, a plurality of drums mounted thereon and to which one end of the coiling curtain is connected, together with suitable actuating mechanism for revolving the shaft so that when the door is moved in one direction the curtain is wound thereon to open the door and when the door is moved in the other direction the curtain is unwound therefrom, thus closing the opening. Suitable guideways for the edge portions of the curtain are employed either on the face of the wall in which the door is made, or on the faces of the door jamb. The drums as usually employed in this type of apparatus are made as integral structures and are adapted to be forced onto the shaft from one end therem after the.

curtain is removed from the opening and 1n so dolng to be ad usted to position and thereafter to be secured in place by means of set screws or other similar devices, and then the curtain 1s refastened thereto.

place the drums on the shaft and to adjust and secure them in place, then secure the is set in place.

The object of my invention is to overcome this difficulty and in so doing to provide a hinged drum adapted to beplaced on the shaft after the shaft is set in place, The

required number of drums may be placed in position and secured in place on the shaft and the curtain then connected to the drums.

The invention, therefore, more particularly;

relates to the construction of the drum employed in this type of apparatus. This be placed over the same making it In assembling the parts of an apparatus of this type it has, therefore, been customary to drum is preferably made in parts which are hinged together so as to swingsufliciently far apart to span the drum and thereby to relatively simple to place each drum in the required 7 position on the shaft. The drum is furthermore so constructed as to have the parts thereof clamped about the shaft to secure the same in position thereon. To this end the adjacent ends of the parts of'the drum are provided with walls in which in oppositely disposed positions there are notches for the reception of a draw or tie bolt which may be readily putin place from either side of the drum and when the nut of the bolt is caught thereon it cannot possibly fall out, thereby facilitating the drawing'up of the bolt to secure the drum in place on the shaft, as will be hereinafter more particularly described.

In 'the drawing F igurel is a sectional elevation illustrating the use of the apparatus in which my present invention is incorporated,

Fig. '2 is a front elevation section of the same,

Fig. 3 is a sectional elevation showing the parts of the drum swung open,

Fig. 4 is an elevation of a shaft showing the drums mounted thereon, f

Fig. 5 is a side elevation of a drum made in accordance with my present invention,

Fig. 6 is a bottom plan view of the same,

Fig. 7 is a section on line 7-7, Fig. 5, and

Fig. 8 is asection on line 8-8, Fig. 5.

In the drawing a portion of a wall is indicated at 1O. This is. provided with an opening 11 for a .door or otherwise. The opening is adapted to be closed by-means of and partial a coiling curtain 12 made of steel slats, or

otherwise, interlocked in any suitable manner to be wound and unwound to andffrom a drum, or-a plurality ofidrums. One of the drums to which the coiling curtain is connected is indicated at 13 and is mounted on a shaft or barrel 14. At the ends thereof the shaft 14 is provided with reduced extensions 15 adapted to be mounted in suitably supported bearings 16. These parts, together with a suitable actuating or oper- Ill ating mechanism, may be enclosed in a housing 17. Also as indicated the face of the wall is provided with suitable guides 18 in which the edge portions of the coiling curtain operate in being wound upon and unwound from the drums. These parts of the apparatus, as will be understood, are more or less standard equipment and While no particular mechanism is illustrated for operating the shaft, any of the devices well known in the art may be employed for this purpose so that the shaft may be actuated either manually or by a motor, as circumstances may require.

As hereinbefore stated the invention in the present case relates more particularly to the construction of the hinged drum members upon which the curtain is mounted to be raised and loweredby being woundupon and unwound from the drums. The construction of the improved drum is clearly illustrated in Figs. 5 to 8 inclusive. As shown this drum comprises two parts, indicated at 19 and 20. The drum member 19 includes an outer flange 21 and an inner concentric flange 22 which are connected by a centrally disposed web 23. In these respects the drum member is correspondingly made to include an outer flange 24, an inner flange 25, and a connecting web 26. The webs 23 and 26, as illustrated, may be provided with holes to conserve material and reduce weight.

The corresponding ends of these members of the drum are pivotally connected to one another. As illustrated one end of the drum member 19 may be recessed, as indicated at 27, to receive theadjacent end of the'drum member 20, which is correspondingly recessed, as indicated at 28 to receive the adj acent end of the drum member 19. These abutting ends of the drum members are preferably reinforced by suitable bosses in which there are registering holes to receive a bolt 29 by which these parts of the drum are pivotally connected to one another. This pivotal connection is such, as illustrated in Fig. 3, as to permit the opposite ends of the drum members to be separated sufliciently far to permit them to span the shaft or barrel with which they are to be associated and consequently tobe passed over the barrel at any portion of its length. Of course, it will be furthermore understood that the inner flanges 22 and of the drum members'are designed to be of substantially the same diameter as the outer diameter of the barrel shaft or slightly less than the barrel shaft diameter in order that when properly placed the parts of the drum may be drawn together and thus secured in position after having been placed,

as -may be necessary, on the shaft or barrel. The end of the drum member 19 opposite its pivoted end is constructed to comprise a wall 30 and similarly this end of the drum member 20- is made to comprise a, wall 31.

The wall 30 is formed to include oppositely disposed bosses 32 and 33 and in like manner the wall 31 is formed to include oppositely disposed bosses 34 and 35. In the boss 33 there is a transversely disposed notch 36 and in the boss 34 there is a corresponding transversely disposed notch 37.

The notches 36 and 37 are adapted to receive a bolt 38 on which there may be employed suitable washers 39 and 40. The bolt 38, as will be readily understood, is employed to draw the parts of the drum together to secure the same in an adjusted position on the shaft or barrel. It will be appreciated that because of the oppositely disposed notches in which the connecting bolt is received this bolt may be readily placed in position from either side of the drum and the nut of the bolt threaded thereon. Furthermore, as soonas the'nut has engaged the thread of the bolt the bolt will be maintained in position within the notches, that is to say, after the nut has been engaged on the bolt the bolt cannot fall out or away from the parts before the nut is drawn up to bring the parts of the drum together and secure the same in position on the shaft or barrel.

As is customary the curtain is connected to the drum. For this purpose, as illustrated, the drum member 20 is provided with a flat surface 41 and a recess 42 against and into which the parts'of an angle bar 43 contact and fit and by means of which and a suitable bolt or screw 44 the coiling curtain is attached to the drum. Obviously any desired or required number of these drums may be employed in any given installation depending upon the width as well as the length of the curtain.

In assembling the parts of the apparatus in which the improved type of drum is included, the shaft may first be set in its bearings, then the curtain connected to the drum and the drum and curtain mounted on the shaft by having the parts of the drum spread to span the shaft, whereupon the parts of the drum may be closed around the shaft and null llU

secured in position thereon. a In securing each drum in position on the shaft the clamp bolt employed therewith is first passed into the drum from the side thereof in a direction substantially parallel to the shaft, then the bolt is turned to a position transversely disposed to the shaft and at the same time is passed through the space provided therefor by the 3 notches 36 and 37 in the bosses 33 and 34. Obviously this may be accomplished with equal facility from either side of the drum which is a material advantage in many instances. It will also be noted that the parts of the drum are so designed that when the bolt is drawn up there is an appreciable space between the walls 30 and 31 in order to make it possible to secure the drum on the shaft, and moreover the inner surface of the inner concentric flange 22 which fits around the drum may be roughened to a sufficient extent to grip the shaft to insure the drum being maintained in position thereon.

From the foregoing description it will now be appreciated that in the use of the drum as illustrated and described the parts of the apparatus with which it is employed may be crated and shipped separately and the parts assembled where they are to be used; that the power shaft and its actuating devices may be set in their required positions before the drums and curtain are mounted therein: that when all the parts are assembled there is no liability of the drums shifting because of set screws working loose, and that in the event of a drum becoming broken it may be readily replaced without the difficulty and expense of taking down the whole apparatus in order to insert a new drum. From the foregoing therefore, the construction of the drum will be easily understood and the advantage of the use thereof readily appreciated.

I claim as my invention:
