This invention relates to apparatus for holding The reels are wet wet reels and for maintainingthe desired tensionon thepaper as itis fed to the dryer.

Another object ofthe invention is toprovide such a reel holder with guides that enable it to serve equally well for holding a single reel or a plurality of reels; and it is a feature of the invention that the apparatus is simple, inexpensive to manufacture, and that it is convenient to use, there being no adjustments required regardless .of the number of reels with which it is used and regardless of the diameter of the respective reels. Inorder to avoid possible damage to pictures as the result of convolutions of the paper becoming "partially dry while reeled up and in the holder, this invention includes means for keeping ."the paper wet while in the" holder.

Figure 3 is a longitudinal sectionalview on the line 3-3 of Figure 1.

The reel holder comprises a trough having a substantially semi-cylindrical bottom Ill connected to end walls II and I2. These end walls are soldered or' otherwise integrally connected with the opposite ends of the bottom MI, and the end walls extend a slight distance below the bottom l and have outwardly turned flanges I4 which serve as legs for supporting the holder on a table or other surface.

The bottom It and the end walls II and. i2 are preferablysheet metal. The bottom extends upward to beads l6 formed by turning over the side edges of the sheet metal from which the bottom is constructed. These beads 16 provide additional strength along the edges of the trough.

The end walls H and I2 extend for a substantial distance above the beads It, and support a rod l8 that extends for the fulllength of the trough. This rod is held against endwise displacement by walls H and I2.

and they are passed through a dryer before the individual pictures .on the strip are cut apart and .sorted. 1

It is an object of this invention to provide improved apparatus for holding one or more of the bushing 2 I.

, l 2 Guides 20 are supported from the rod l8. Each of these guides 20 is a channelrshaped element,

' preferably of sheet metal; and the rod [8 extends through the opposite sides of each channel and supports the guides 20 for angular movement about. the axis of the rod.

The guide 20 nearest to the end wall H is spaced from the end wall by a bushing 2| on the rod l8. The guides 20' are spaced from one another-by similar bushings 22 on the rod l8, and the guide 20 nearest the other end wall I2 is likewise spaced from the end wall by a sleeve or I The drawing shows reels 25 of photographic paper resting on'the. bottom Ii] and with paper from the outercon'volutions paying out through the adjacent guides 28 and held against lateral displacement by these guides 20. The run of the paper passing from each of the reels 25 to a dryer (not shown) is indicated by the reference character 26. The paper passes under the rod I8 and along the guide 20 to a feed belt 21 of the The upper end of the guide 20 rests on the belt 2'l. There is preferably a separate belt 21 for each reel. By preventing transverse dis placement of the run of the paper being withdrawn from each reel, the guides 2!] keep the reels themselves in spaced relation to one another. No matter how small the diameter of the reel becomes, the run of the paper 26 passing along the channelled guide 20 holds the reel against transverse displacement in the trough.

The drawing shows the trough of the reel holder with a semi-cylindrical bottom, and this shape of bottom is preferred. The curve of the bottom It can be less than but it is a feature of the invention that the sides of the trough are steep enough to prevent the reel 25 from rolling up the side of the trough as the paper is drawn from the reel. A radius of curvature for the bottom of the trough somewhat greater than the original diameter of the reels 25 is preferred. This shape of bottom makes the reels pay out evenly with very little friction, and without danger of becoming scratched.

It is also advantageous to have the trough deep enough to immerse a substantial portion of the reels 25 in water because the buoyancy of the water decreases the weight of the reels and reduces the friction of the reels on the bottom ID.

The curved shape of the bottom I0 facilitates washing of the reel holder, but it will be understood that shapes other than a semi-cylindrical shape can be used. Other changes and modifications can be made, and some features of the invention can be used alone or in different comradius of said semi-cylindrical bottom being somewhat greater than the radius of thewfully wound reels with which the apparatus is. intended to be used, and said end walls extending to a level above the top edges of thesemi-jcylindrical bottom and extending to a level below the bottom to provide feet to stably support the apparatus, a rod located above one of said top edges and supported by said end walls, a plurality of guides extending within .the troughand spacedirom one another lengthwise .of the ltrough, ea.ch. of said guides having .sides .space'dfrom one.ano',ther by a distance slightly. greater r than Ithe width of one of the reels, a ,bearingsonitheendnf .each

Apparatusfor holding reels of photographic paper, said apparatus including a substantially "semi-cylindrical bottom and end walls forming a trough for holding water in which the reels are :at least partially submerged when in the holding apparatus, said bottom comprising the support for reels within the apparatus and the radius of said semi-cylindrical bottom being somewhat greater than the radius of the fully wound reels withw-hich the apparatus is intended to be used, a plurality of guides connected with one side of the-trough and spaced from one another lengthwise of the trough and each of which has upstanding sides spacedfromlone another by a distance .slightlygraaterthan'the width ofone of the reels and forming achannel through-which paper payed out from the reel passes, eachroi said channels having one lendcommunicating with the trough and having its length extending outward from the trough in a direction substantially normal to the length of the trough.
