HANS C. HUTTEBALLE AND CHRISTIAN MORLER, OF BOISE, IDAHO.

PHOTOG-RAPHIC APPARATUS.

Specification of Letters Patent.

Application filed February 21, 1910.

Patented Sept. 27, 1919.

Serial No. 545,154.

To all whom it may concern:

Be it known that we, HANs C. HU'r'rn- BALLE and CHRISTIAN Montana, citizens of the United States, residing at Boise, in the county of Ada and State of Idaho, have invented certain new and useful Improvements in Photographic Apparatus; and we 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 appertains to make and use the same.

This invention relates to improvements in photographic apparatus, and its object is to provide a compact and eiiective drying ma chine for photographic reproductions.

To those experienced in the art it is well known that it consumes a great deal of time to dry photographic prints, after washing, whether the prints are on thin paper or post cards, and besides this where the prints are dried by the ordinary process, unless they are placed between blot-ters, they tend to curl up, which occasions additional labor in straightening the prints out. l Vith respect to the time it takes to dry photographic negatives, whether on glass or films, the same remarks apply, with the exception that where the negatives are on glass there is no curling up like would be the case in films or prints.

While the invention is primarily designed for drying post cards and prints, it will be understood that the broad application of the invention is equally applicable to drying plates and films, and in the following description the use of the word print is intended to cover not only cards or prints but any other photographic production requiring drying.

Broadly, the invention consists in providing means for holding one or a plurality of photographic productions to be dried while an air current is generated to pass around the prints and quickly dry them, and in the particular application of the invention we provide a stationary support for the printswith a rotary fan, driven by any suit able power, so located as to generate currents of air passing between the prints, which are contained in suitable holders.

While the invention is not restricted to the exact details shown and described, still, for the purpose of disclosure, reference is had to the accompanying drawings illustrating a practical embodiment of the same, in which drawings like letters designate the same parts in the several views, and in which Figure 1 is a view in side elevation. Fig. 2 is a top plan view. Fig. 3 is a central cross section on the line 33 of Fig. 2. Fig. 4 is a fragmentary inverted plan view of a motor, showing a pair of injection nozzles in section. Fig. 5 is a sectional view along the line 5-5 of Fig. 4E and showing the upward direction of the nozzles with relation to the impact vanes on the motor, and Fig. 6 is a perspective detail view of one of the print holders, a portion of the covering being broken away.

1 designates a container in the form of a cylindrical pan, provided with brackets 2 supporting a guard rail 3, disposed along said pan and provided with a plurality of radially disposed clips 4 on its upper rail, cooperating with a plurality of vertically disposed radial clips 5 carried by a circular member or plate 6, supported by the hollow shaft 7 encircling a rod 8, which rod is conically bored at its lower end, as at 9, to form a bearing or seat hereinafter referred to.

10 designates a rod extending across the apparatus and secured at its ends by any suitable clamping means, as 11, (Fig. 2) to the top rail of the guard. Centrally of the bar 10 there is aftiXed a sleeve 12, projecting upwardly above said bar around said rod 8, and forming at its upper edge a support for the hollow shaft 7. The lower end of the sleeve 12 projects downwardly below the bar 10, and is provided with a set screw 13 forming a locking means for the rod 8.

14 designates a base bearing within the container 1, and between this stationary bearing 14 and the bearing 9 is disposed a rotatable spindle 15, carrying at its upper end a fan or other suitable drying member 16, and at itslowcr end carrying a motor 17, detachably secured to the spindle by means of a set screw 18, and being provided on its underneath face with a plurality of vanes or impact blades 19, cooperating with a nozzle or a pair of nozzles 20 directed upwardly and inwardly toward said impact blades. Suitably supported between said motor 17 and fan 16 is a guard 21 for preventing the upward splash of the water when the motor is driven by water power. In the drawings this guard is shown as comprising an inverted pan of such a dimension that it rests against the inside wall of the container, and is held in position by a plurality of pivoted fingers 22, (Fig. 2).

It will be understood that the nozzles 20 extend through the container, as shown in Fig. 1, and are connected by means of a rubber tube or piping with the driving power. The container is also provided with an outlet 23, where water is the motive power.

In'Fig. 6 is illustrated a suitable form of print holder which simply consists of a wire frame 24, formed from hinged members and provided with a covering of cheese cloth 25, or other suitable material, between which theprint or card is placed. When used in connection with a plate or film having a soft gelatin surface, the frame could be slightly changed to be adapted to this particular use, omitting the cheese cloth which might otherwise abrade thephotographic surface. One of these holders is shown placed in position in both Figs. 1 and 3, that is in a vertical position and supported by the clips 5 and 4 radiallyof the axis of the fan.

The operation is believed to be obvious from the foregoing description, but it might be stated that when the prints are all placed around the machine, in the position shown in Figs. 1 and 3, by injecting any suitable fluid, such as water, through the nozzles 20, the motor 17 will be rapidly rotated, carrying the fan with it, but causing upwardly directed air currents to pass through the print supporting frames and thus quickly drying the prints. \Vhere water is used as a motive power the pan 21 prevents any upward splash of the water while'the water runs out through the outlet 23, but it is obvious that air might be the driving means, whether cold or hot, in which event the cover or pan 21 would not be used, and the driving air, whether cold or warm, assists the fan in drying the prints.

Of course it w1ll be understood that other motive powers may be used for driving the spindle 15, and the broad invention is, therefore, not restricted to the specific means shown.

Having thus described the invention,what we claim is 1. The combination of a revoluble fan, means for revolving same comprising a motor directly connected with the shaft of said fan, a fiuid injecting nozzle directed against said motor, and means for supporting the photographic productions to be treated di rectly above said fan and in planes substan tially at right angles to the plane of revolution of said fan, substantially as described.

2. The combination of a vessel, a vertically second support provided with a plurality of holding clips, both sets of said clips being arranged radially with reference to said fan, one set being arranged in a horizontal direction and the other in a vertical direction adjacent said fan whereby said clips receive and hold the photographic productions to be treated edgewise 1n substantially parallel planes in a position to allow of the direct passage therebetween ofthe air current generated by said fan, substantially as described.

a. The combination of an open cylindrical support forming also a guard, a rotatably mounted spindle provided with a fan revoluble within said guard, a bar extending across said guard, a sleeve centrally of said bar provided with a set screw, a rod slidable in said sleeve and forming the upper bearing for said spindle, a hollow shaft encircling the upper end of said rod and resting on said sleeve, a second support surmounting said sleeve, vertically disposed clips arranged radially of said second support, horizontally disposed clips arranged radially of said first support or guard, and means for rotating said fan, substantially as described.

5. The combination of an open cylindrical support forming also a guard, a rotatably mounted spindle provided with a fanrevoluble within said guard, a bar extending across said guard, a sleeve centrally of said bar provided with a set screw, a rod slidable in said sleeve and forming the upper bearing for saidspindle, a hollow shaft encircling the upper end of said rod and resting on saidsleeve, a second support surmounting said sleeve, vertically disposed chps arranged radially of said'second support, horizontally disposed clips'arranged radially of said first support or guard, and means for rotating said fan comprising a motor provided with impact vanes on its underneath face and injection nozzles directed against said impact blades or vanes, substantially as described.

6. In apparatus of the character described,

the combination of a vertical spindle, a fan mounted thereon, means for rotating said spindle and fan for generating upwardly directed air currents, supporting means arranged above said fan for the photographic productions to be treated, comprising a lower set of radially disposed horizontal clips, an upper set of radially disposed vertical clips in alinement with said clips and a frame formed of two hinged open members provided With a covering of cheese cloth or similar material mounted in said clips for holding the photo raphic productions to be treated between said covered frame in a substantially edgeWise vertical position, substantially as described.

In testimony whereof, We afiix our signatures, 1n presence of tWo Witnesses.
