. ApplicationApril 25, 1949, Serial No. 89,440
This invention relates to improvements in to bacco barns employed in the curing of' tobacco and more especially to ventilating apparatus adapted to be mounted at the ridge of gable or A-type roofs of. tobacco barns and which has means depending therefrom 'for, adjusting the same, whereby the, amount of air passing upwardly through the tobacco being dried may be regulated. In the curing oftobacco, the tobacco is placed on tobacco sticks which are arranged in tiers in the interior of a barn and in order to insure uniform curing of the tobacco within a particular barn, it is necessary that air be admitted at the lower part of the barn and to further provide ventilating means at the top of the barn from which the air may escape.
There are many tobacco barns now in use which are not provided with a. suitable ventilating means to permit the air to escape from the barn, and it is, therefore, an object of this invention to provide a simple and easily constructed ventilating apparatus which may be applied to exist- 2 Claims. (Cl. 98--52) ing tobacco barns with a minimum of additional labor and materials.
, It is another object of this invention to provide a longitudinally extending opening at the ridge of a gable-roofed tobacco barn, the opening extending substantially the entire length of. the barn, and to further provide a plurality of frame members of substantially the same width as the opening, each of which is adapted to be secured to two adjacent rafters at their junction point, these frame members extending a substantial distance above the opening. Wall members are and adjacent opposite ends of each of the cover members, are control bars which extend downwardly and terminate closely adjacent the-floor of the learn where they are within easy reach of anoperator so that they may be raised, thus opening the cover members for permitting egress of air from within the barn, there being suitable means associated with these depending bars for locking them in any desired elevated position.
Some of the objects of the invention having secured to opposed edges of these frame nembeen stated, other objects will appear as therde- I scription proceeds, when taken in connection with'the accompanying drawings, in which- Figure 1 is an isometric view of a. tobacco barn provided with a gable or .A-type roof and showing the invention applied thereto; V c
Figure 2 is an enlarged vertical sectional view taken'substantially along the,line 2-2 in Figure 1 and showing the ventilating means in closed position; a I Figure 3 is a view similar to Figure 2 but showing the ventilating means in open position;
Figure 4 is an enlarged vertical sectional view through a tobacco barn with parts omitted and is taken substantially along the line 4-4 in Figure 1;
Figure 5 is an enlarged vertical sectional view with parts broken away and is taken substantially along the line 5-5 in Figure 4;
Figure 6 is an enlarged fragmentary sectiona plan view taken substantially along the line 6-6 in Figure 4;
Figure 'l is a view similar to Figure 6., and is taken along the line 1-1 in Figure 4.
Referring more specifically to the drawings, the. numeral l0 broadly designates a tobacco barn, the foundation of which comprises a plurality of' concrete blocks ll, alternate ones of which are turned on their sides to expose their air spaces I2 and to allow air totpass there- .through. Sills l3 are disposed on top of theblocks H and support a plurality of spaced uprising studs or frame members l4,,on the top ends'of which the usual plate members I5 are secured.
The lower end of gable rafters I6 and I! are secured on opposed plate members [5 and corresponding rafters I6 and I! are joined together at their upper ends, the usual ridge board being omitted from tobacco barns of this type. c
The barn is provided with a plurality of tier poles 20, only two of which are shown in Figure 4, and on which tobacco sticks with tobacco thereon are adapted to be placed for a curing operation. These tier poles 20 are usually suitably secured at their ends-to'the uprising studs The rafters l6 and H are covered with a suitable roofing material, 2|, which, in barns of this type, usually covers the entire area defined by the rafters l5 and [1. However, in this instance,
the covering is cut away at the comb portion of the barn in the event that the present ventilating apparatus is to be applied to an existing barn, and in the even-t of a new barn, obviously the roofing material would terminate a substantial distance from the junction point of the rafters l6 and H at each side thereof, to thus provide an opening which extends substantially the entire length of the comb portion of the roof 2 l.
Obviously, the rafters I6 and I1 span the longitudinally extending opening at the comb portion of the roof 2|. The proximate sides of the outermost of these rafters l6 and I1 have suitable frame or spacer members 24 and 25 secured thereto and extending a substantial distance above the opening. There is also provided a pair of frame members 26 and 21 which are identical to the frame members 24 and 25 and which are secured to opposite sides of the centermost of the rafters l6 and H as shown in Figure 5.
It is to be understood that a barn of substan tially greater length than the barn shown in the drawings, would, necessarily, have additional frame members, such as the frame members 24 to 21, inclusive, secured to others of the rafters, not shown. However, the distance from one of the framemembers 25 to the frame member 21, for example, maybe approximately eight feet.
Secured to opposite sides of the frame members. 24 to 21, inclusive, are vertical side wall members 30 and,.3|, the lower edges of which engage opposite edges of the opening formed at the comb portion of the roof. Normally resting on the upper ends of the frame members 24 and 26 is a planar cover member 32 which also rests on the side wall members 30"and 3| and the side edges of the covermember32 extend a substantial distance beyond the side wall members 30 and 3| A similar planar cover member 34 normally rests on the upper ends of the frame members 25 and 21, and on the upper edges of the vertical side wall members 30 and 3| and also extends a substantial distance beyond the side wall members 30 and3l. r
from the position shown in Figure 2 to the position shown in Figure3.
It will be noted in Figure that the remote surfaces of theupperportion of the control staffs .35 and 36 slidably engage the proximate surfaces ofthe frame members 24 and 26 while the remote surfaces of the control staffs 31 and 38 slidably engage the proximate surfaces of the frame members and '21. It is thus seen that the control staffs 35 and 3B and 31 and 38 prevent longitudinal movement of the cover members 32 and 34 respectively, as they are raised and lowered for. adjusting the sizeof the opening at the upper ends of the side walls and 3|.
All of the control staffs to 38 being identical, by referring. to Figure 4' there is shown the control staff 31 and it is seen that these'control staffs 35 to 38, inclusive, are mounted for vertical sliding movement in suitable guide blocks 4| and 42 being shown in detail in Figures 6 and '1, respectively. It will be noted in Figure 6 that the guide block 4| bears against spacer blocks 41a and 4 b and the guide block 4| with its spacer blocks 4m and 4|b is secured as by nails 43 to the uppermost of the tier poles 20 shown in Figure 4. The guide block 42 is identical to the guide block 4|, there being spacers 421a and 421) against which the block 42 is adapted to be secured by suitable nails 44 which also secure the guide block 42 and its spacer blocks 42a and 42b to the lowermost of the tier poles 20 in Figure 4.
Referring to Figure 4 it may be observed that the lower portion of the control staif31 is provided with aplurality of bores 46 which are adapted to be slidably penetrated by a locking pin 41 (Figures 4 and 7), this pin 41 being adapted to engage the upper surfaces of the block 42 and the lowermost of the tier poles 20 in Figure 4 to thus hold the cover members 32 and 34 in a desired elevated position. It is to be understood that allof the control staffs 35 to 38, inclusiveare mounted in a manner identical to the control staff 31 in Figure 4.
Referring to'Figures 2, 3 and 5, it may be observ'edfthat each or the control staffs 35 to 38 is provided with a block or stop member 50 which is suitably secured thereto and which is adapt-ed to engage the lower edge of the corresponding frame members 24 to 21, inclusive, to thus prevent an operator from elevating the cover members 32 and 34 above a predetermined position.
The side walls 38 and 3| and the closing frame members 24 and 25 thus provide an effect similar to that of a stacker chimney while the cover members 32 and 34 not only serve as a roof for the opening at the comb of the roof but serve to control the size of the opening. Since the cover members are flat and of relatively thin material, they will not interfere with the normal currents of air passing over and under them while in open position. The side walls 30 and 3| and the flat cover members are conducive to prevent turbulence of air in the case of winds of relatively high velocity and also to prevent down drafts through the-comb opening. Y
In the drawings and specification there has been set forth a preferred ernbodim'ent ofthe invention, and although specific terms are em ployed, they are usedin a generic and descriptive sense only, and not for purposes of limitation, the scope of'the invention being defined in the claims.
I claim:
