FILM DRIER Filed Sept. 2, 1947 F56! FIG. 2
I I L N J. TQTRIMBLE Patented Jan. 24, 1950 ITED STATESPATJENT OFFICE FILM DRIER Joe T. Trimble, Tulsa, Okla.
Application September 2, 1947, Serial No."771,65-8
Claims. 1
This invention relates to improvements in him dryers, and more particularly to a dryer of simple, inexpensive and practical construction, designed for the rapid drying of photographic film in a dentists office or clinic.
One of the objects of the invention is to provide a casing with an internal partition defining a steam-lined passageway through which air, preferably heated, is circulated for the drying of film suspended in the casing.
Another object is to provide a device of this character comprising trays of reticulated material designed to support any suitable absorbent to absorb the moisture from the circulating air.
A still further object is to provide a device of this character including a heating lamp, circulating fan and time switch, all arranged in a common circuit, whereby after a predetermined period of time, the fan will be halted and the lamp will be extinguished by operation of the time switch.
With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims:
In the drawing:
Fig. 1 is a front elevation of my improved dryer with the doors in open position, and diagrammatically illustrating the electric circuit for the fan, lamp, and switches.
Fig. 2 is a side elevation, partially broken away, to show one of the reticulated trays.
Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2.
Referring to the drawings, 4 designates a casing having a vertical rear wall 5, side walls 6 and hinged doors 1 which close the front of the casing. The top 8 and bottom 9 is each preferably of semi-cylindrical shape, and as a vertical partition Ill is arranged in the casing midway between and parallel to the side walls 6, a streamlined passageway is provided within the casing. A horizontal perforated partition H is mounted in the casing at the top of and to one side of the partition l0, and it supports any suitable type of electric fan l2. At the opposite side of the partition ill, means are provided for the support of film 13. Such means may consist of horizontal rods l4 projecting forwardly from the rear wall 5 of the casing.
Below the partition H, I arrange a second horizontal partition l5 which is slottedto slidably accommodate perioratedtrays l6 adapted to support any suitable absorbent agent which will remove moisture from the circulating air. When one of the doors 1 is open, these trays may be removed for replenishing or revivifying the absorloent.
A source of heat, such as an infra-red electric bulb :1 is preferably arranged within the top 8 so as to heat the .air as it circulates.
For the purpose of controlling the fan and heat bulb, a conventional time switch in may be secured to the front of the bottom 9 of the casing, and the .ian motor, heat bulb and the time switch are all arranged a circuit l9 having a source of electricity supply Zll, and a manuallly controlled switch 2 I In operation, it may be understood that when one of the doors I is open, film may be suspended on the rods M, and then if the door is closed and the time switch 18 is set for a predetermined period of time, and the switch 25 is closed, the fan will circulate the air and the heat bulb will warm the same. As moisture is extracted from the film, it will be absorbed by the absorbent in the trays H5. At the expiration of the time period, the switch l8 will automatically open the circuit and then the dried film may be removed.
In time, the absorbent becomes saturated and it may be replaced or revivified.
While I have disclosed what I now consider to be a preferred embodiment of the invention in such manner that the same may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed without departing from the spirit of the invention, as expressed in the following claims:
What I claim and desire to secure by Letters Patent is:
1. A film drier comprising a vertically disposed approximately rectangular casing body having parallel rectangular side walls and parallel front and rear walls, each of the front and rear walls being of substantially oval shape, a substantially semi-cylindrical top and bottom for the casing, a substantially vertical partition arranged in the casing parallel to and about midway between the side walls and defining with the casing a substantially oval-shaped passageway, means in the passageway for supporting film, means in the passageway for forcing air to circulate therethrough, perforated trays supported in the passageway for receiving a moisture absorbing agent, and a door forming a part of one of the walls.
passageway for forcing air to circulate therethrough, removable means in the passageway for supporting moisture absorbing material, and
doors forming part of the front wall and hingedly connected to the side walls.
3. A film drier comprising a vertically disposed approximately rectangular casing body having parallel rectangular side walls and parallel front and rear walls, each of the front and rear walls being of substantially oval shape, a substantially semi-cylindrical top and bottom for the casing, a substantially vertical partition arranged in the casing parallel to and about midway between the side walls and defining with the casing a substantially oval-shaped passageway, means in the passageway for supporting film, means in the passage- Way for forcing air to circulate therethrough, a heating element connected to one of said semicylindrical parts and arranged in said passageway, a horizontal partition arranged across the passageway having slots therein, perforated trays slldable in the slots of the horizontal partition, and doors in one of said walls.
4. A film drier comprising a vertically disposed approximately rectangular casing body having parallel rectangular side walls and parallel front and rear walls, each of the front and rear walls being of substantially oval shape, a substantially semi-cylindrical top and bottom for the casing, a substantially vertical partition arranged in the casing parallel to and about midway between the side walls and defining with the casing a substantially oval-shaped passageway, means in the passageway for supporting film, means in the passageway for forcing air to circulate therethrough,
moisture absorbent supporting means arranged with said passageway, and a door forming a part of the front wall to provide access to the film supporting means. 1
5. A film drier comprising a closed casing in-' cluding a vertically disposed approximately rec- 3 tangular body having parallel rectangular side walls and parallel front and rear walls, each of the front and rear walls being of substantially oval shape, a substantially semi-cylindrical top and bottom for the body, a substantially vertical partition arranged within the casing parallel to and about midway between the side walls and defining with the casing a substantially oval-shaped passageway, means in said passageway at one side of the partition for supporting film, a horizontal partition in the passageway at the opposite side of said partition, a driven fan arranged in the passageway and supported by the horizontal partition for circulating air through the passageway, moisture absorbent supporting means arranged within the passageway, a heating element in the passageway for heating the circulating air, and hinged doors forming part of the front wall to permit access to the film supporting means and moisture absorbent means.
