c. BORNMANN Filed May is, 1927 INVENTOR CARL BORNMANN AT'i'O Y Patented a. 27, 1931 UNITED S -res PATENT OFFICE" CARL BORN-MANN, OF BINGHAITON, NEW YORK, ASBIGNOR, BY 'MISNE ASSIGNMENTS,
TO AGII'A ANBOO CORPORATION, OI 'BHGHAH'I'ON, NEW YORK, A GOBI'ORLTION OI i NEW YORK rim: racxacn Application ma. Kay 1c. 1921. Serial No. 101,790.
A type of photographic film pack e rap the rece tacle. -Generally these receptacles are ma e of wood in the form of a small block hollowed out on its inside and being provided with metal or other suitable end pieces closing the interior of the receptacle to the light. Metal receptacles are in some instances su tituted for the wooden ones,
, but because of its cheapness and eas handling properties, the wooden-receptac es are generally preferred.
It has been found by experience that in usin wooden rece tacles particularly those whidh have been reshly cut, certain fumes and, as are given off by the fresh cut wo'od whic are deleterious to the photographic film subsequently coiled therein, producing what is generally known as fchemical fog "on the film, thus destroying it entirely orat least greatly reducing its sensitive image receiving quality and impalrmg its use as a photographic film.
Also in the "manufacture of these wooden receptacles, the material is so cut that at different oints about the receptacle, the wood is relatively thin between the hollowed interior and the outside. It will be understood, therefore, that if the wood comprising the re- 'ceptacle happens to be rather porous and loose grained, strong sunlight might readily filter through the interstices of the wood and fo the film inside the receptacle. j he primary object of my invention is to prepare such film receptacles so as to eliminate the possibility of fogging the film by either the chemical action of the wood or from actinic light reaching the film through the wood. I
More specificially, it is an object of my invention to treat such wooden receptacles with a substancewhich at once seals the gases or fumes in the wood thus preventing their escape to act u on the film, and to render the receptacle lig t tight.
Other obj ects and advantages in details of construction and operation will be apparent as the description roceeds, reference now being had to the gures of the drawin s whereinlike reference numerals indicate lie parts.
In the drawings Figure 1 is a perspective view of a wooden film receptacle or package to which my invention is applied.
Fi ure 2 is a detail end view thereof the I met end of the package being removed Reference numeral 1 refers to a wooden film receptacle of the character described, which is hollowed out interiorly as at 2'to"re-- 'ceive a coil of photo a-phic film 3 guided within the receptacle y means of the metal spring uide 4, one end '5 of which extends outwar y through the slit 6 along one edge of the receptacle and is bent back over the top wall 7 thereof. The slit 6 is provided at top and bottom with strips of velvet or other suitable material 8 between which the film 3 may be withdrawn or inserted. These strips efiectively prevent the entrance of light through the .slit to theinterior of the receptacle. One end 9 of the film projects beyond the slit 6 for convenience in threading the film through a camera and adjacent this end 9 film is preferably notched inwardly from its sides as at 10 whereby the film may be readily severed at this point to eliminate the kink in the film caused by the projecting end. This renders the film strip more easily threaded and more adaptable to coiling upon itself within the receptacle when fed therein.
The ends of the receptacle are. preferably closed by means of metal end pieces 11, one corner of which is providedwith an extension 12 engaging over the corners of the receptacle for the double purpose of retaining the end 5 of the film guide in position and .for preventing the entrance of light into the receptaclethrough the ends of the slot 6.
It will be noted with reference to Figure 2 particularly that when the interior of the receptacle is hollowed out, the front and rear walls thereof are left relatively thin as at 13. In the event that the wood from which the receptacle is made is porous, it will be understood that in strong sunlight actinic rays might leak therethrough and 0 the film 3. As has been heretofore ex lain it also occurs that when the woo en receptacle has been cut and hollowed out to the desired size and form, fumes and gases emanating from the freshly cut wood are apt to attack and chemically fog the film.
To obviate the likelihood of spoiling the film by either light fog or chemical fog, due to the foregoing causes, I treat the receptacle after it has been cut to size and form and before the film has been laced therein, with a substance which provi es a coating on said receptacle inside and out, which coating not only seals the wood gases from escaping, but also efiectively prevents the light from passing through the wood. This treatment is preferably accomplished by dipping the receptacles into a solution of silicate of soda carrying therein a suitable black stain. Upon drying, the silicate of soda forms a seal or coating on all parts of the wooden receptacle which efiectively prevents the escape of gases therefrom. The black stain, of course, colors the receptacle black inside and out, thereby eliminating all possibility of reflection of light, the black color tendin to absorb the same. In addition to this, t e solution of silicate of soda and black stain fills the interstices of the wood, thus providing a protection against the passage of light themthrough.
The solution herein mentioned as bein preferable for this treatment is of course lustrative only, and my invention is not limited thereto as there may be other solutions just as readily adaptable to this purpose as the silicate of soda solution.
Furthermore, it will be understood that in the case of wood which is not porous, or in case the receptacles are so cut as to leave the walls thereof thick enough to themselves prevent the passage of light therethrough, the black stain may be omitted from the solution. It will also be understood that where the wood used for these receptacles has been thoroughly dried and cured after cutting so that there is no further possibility of escape of the wood gases therefrom, the silicate of soda solution may be unnecessary. By my invention, however, I have made it possible to use relatively green wood for making up these film packages, without the necessity of going to the expense and delay of drying and curing them before charging them with the photographic film.
In view of the foregoing, I do not limit myself to the exact method and construction herein described, other than by the appended claims.
I claim 1. A wood container, designed and shaped to receive a coil of film, said container having a coating of silicate of soda on the inside walls thereo 2. A wood container, designed and shaped to receive a coil of film therein, the inside walls of said container having a coating of a colored solution of silicate of soda.
CARL BORNMANN.
