, Signor to AmericaniArt-Ghar,
tion of. New Jersey -Inc'., a oorpora- Application July 30, 193:2. S eria l No? 627,020" 6 ii-Claims. (o1.- 202 97)' This invention relatesto an improved apparatus for converting wood into charcoal and more particularly to an apparatus for forming charcoal pencils used by artists when making charcoal sketches. Whileit has been stated-that the device is used for making charcoal pencils, it will be obvious that charcoal in stick formation and used for purposes otherthan drawing may be.
formedin the improved apparatus and that the sticks may be of any lengtlrand diameter desired.
When sticks or rods of wood are converted into charcoal, they have a tendency to warp and become distorted so that they cannot be con-.
veniently held in a persons hand whenused as a pencil and therefore one object of this invention is to provide an apparatus of suchconstruc tion that pressure may be applied to sticksof wood while they are being converted into charcoal and therebyprevent them from warping and alsofreely in the oven and cause the sticks to be quickly converted into charcoal.
Still another object of the invention is in construction, easy to operate, and not liable to get out of order when in use. 7
With these and numerous other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more parl t out in the s ecification and tlcularly pom ed p are set in place uponthe trays 2 and since the claims.
In the accompanying drawings forming a part of this application:
Figure 1 is a perspective view of the improved charcoal forming apparatus with portions of the outer hood broken away; I
Figure 2 is a vertical section taken transverse- 7 1y through the apparatus;
with the front broken away and shown insection;
Figure 4 is a perspective view of the oven en Figure 3 is a perspective view of the outer hood closed by the hood; 7
Figure is a fragmentary perspective view of a wood supporting tray forming part of the apparatus.
Figure '6 is a perspective view showing a numand diameter.. The apparatus comprises briefly an oven 1 in which trays 2 and spacers 3 are to provide a device of this character which is simple ber of the't'rays arranged in tiers and a pressure applying weight in place;
In describing'the invention, 1- shall refer to the drawings in which similar reference characters designate corresponding. parts throughout-the sevi .eral views and in which ldesign'atesthe oven.
This impoved apparatus is employed to forinsticks of charcoal which may be used as pencils or for other purposes if they are of the proper length.
stacked as .shown in Figure 2, a weight 4 for applying pressure to prevent warping of sticks of wood 5 while being convertediinto charcoal and a hood 6 which is open at its bottom inorder that it may beeasily. set in place about the'ovenor removed from the same.
The oven-1 is rectangular in shape as shown in Figure 4 and may .be'of any dimensions desired.-
It is open at its front for access to its interior and in .order to close .the oven after it has been charged, there'has been provided 'a door '7 hinged as shown at8 and carrying a suitable number of fasteners 9'serving not only to secure thedoor when closed but alsoas handles. by means ofwhich the door may be opened and closed; Upper and out of placebut also-retain walls of the hood Handles .15 are. pro- ,videdat opposite-sides of the hood in order that it may be easily lifted.
When theoven is charged, the sticksflof wood trays are formed of corrugated sheet metal "each tray is formedgwith longitudinally extending pockets to receive the sticks. As the trays are placed withinthe oven one above another, a spacing sheet 3 is set in place upon each tray and the weight 4 rests upon the sheet on theuppermosttray of thestack. Openings 16, 17 and 18 are formed centrally of the-trays,- spacing sheetsand weight and therefore, hotpirland' gases may pass upwardly through the stack while the sticks of wood arebeing converted into I charcoal. It also be noted that sidewalls ,of the oven carry front and rear rods 19' corresponding to the rods 14 and servi'ngto engage sides ofthe stack andretain the same in spaced relationto wallslof the oven in order that .agood? control the temperature of the spacewithin the" hood about the oven.
When the improved charcoal forming appara-' tus is in use, the trays are loaded with sticks of wood of the desired length and thickness and the loaded trays are placed in the oven 1, in stacked formation with a spacing sheet upon each tray and the weight resting upon the upper spacing sheet. The door 7 is closed and secured and the hood set in place about the oven. Heat is supplied to the oven by setting it upon a stove or in any othermanner desired and since the hood is formed as a hollow shell filled with insulation as shown at 24, heat will be confined about the oven and the oven retained at such a temperature" that the sticks of woodwill be quickly converted into charcoal. By properly adjusting the valve 20 and plate 22, passage of hot air and gases from the oven and hood can be controlled and the oven retained at the desired temperature.
Since the weight 4 exerts pressure upon the stack of trays and spacing plates, the sticks of wood will be retained in a flattened condition and prevented from warping as they are converted into charcoal and the resulting charcoal will be. in
the form of straight sticks which can be easily held in a person's hand and used as a pencil when making charcoal sketches. The pockets of the trays are v-shaped in cross section and therefore, sticks may be heldfirmly in place therein even if they. are not of a predetermined diameter andalso sticks placed in. the pockets of one tray may be of a different diameter from sticks carriedby another tray. Pressure exerted upon the stack of trays and spacing sheets can be controlled by providing a series of blocks 4 of 'difierent weight or a single block can beused and have flexible wires extending from it over guide pulleys and carrying counterweights.
From the foregoing description of the construction .of my improved device, the operation thereof and the method of applying the'same touse will be readily understood. It will be seen that I have provided a simple, inexpensiveand efl'icient means for carrying out the objects of the invention and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing.
from the spirit or sacrificing any of theprinciples of the invention.
