Singley, Belle Mead, NJ., assignor to Farm Instruments Corporation, New York, N.Y., a corporation of Delaware Original application Nov. 23, 1956, Ser. No. 623,936, now Patent No. 2,931,335, dated Apr. 5, 1960. Divided and this application May 28, 1959, Ser. No. 816,620
4 Claims. (Cl. 119-51) This application is a division of my copending application, Serial Number 623,936, filed November 23, 1956, now Patent No. 2,931,335 entitled Self-Feeding Structures for Animal Foodstuffs and a Method of Manipulating Silage in a Silo and relates to a method of selffeeding foodstuffs to animals and self-feeding structures for animal foodstuffs and more particularly to a method to support silage in a silo and to assure movement of the silage downward in the silo as the lower portion of the silage is consumed by feeding animals to replenish automatically the food supply within the reach of the feeding animal without danger of injury to the animal.
In forming silage the customary practice is to fill the silo with foodstuff such as grass, alfalfa, etc. alone or mixed with corn meal, molasses or other materials. Silage as a mass is a fibrous material. Within a silo the great majority of fibers lie in a horizontal plane. The remainder of the fibers may lie in a vertical position or in random positions. When placed in tension axially, those silage fibers in the mass extending along the horizontal plane contribute strength to the mass; fibers at right angles to a horizontal plane contribute no strength,
while fibers at intermediate angles contribute intermediate strength.
As a basis of comparison, consider a common cotton thread which consists of uni-directional fibers and possesses desirable strength characteristics only when placed in tension. The greater the tensile forces applied the more individual fibers grasp each other and contribute to the total strength of the thread. However, if the threadis placed in compression axially the individual fibers are released from each other and the thread loses its strength. Silage responds in the same way. When the fibers are placed under tension the mass has great strength. However, when the individual fibers are placed under compression the fibers separate and the mass fails easily. If a suspended mass of silage is restrained from expanding upward by the weight of the mass above and is compressed on the sides, the massnecessarily expands downward in the unrestrained direction and the fibers will separate and balloon out.
, The chief object of the present invention is to provide a method of self-feeding foodstuffs such as silage employing this principle.
An object of the invention is to provide a simple method of manipulating silage in a silo to assure ready movement of the silage downward in the silo as the lower portion of the silage is consumed to replenish the food supply within reach of the feeding animal without danger of injury to the feeding animal. Other objects of the invention will be readily perceived by reference to the following description.
The attached drawings illustrate a preferred embodiment of the invention, in which FIGURE 1 is a view partially in elevation and partially in section of the self-feeding structure of the present invention;
FIGURE 2 is a plan view of the foundation and the supporting members taken on the line 11-11 of FIG- URE 1;
FIGURE 3 is a sectional view of the mass constricting members and partial support members of the structure shovm in FIGURES 1 and 2;
FIGURE 4 is a view in elevation of a modified support member in support position;
FIGURE 5 is a view in elevation of the support member shown in FIGURE 4 in retarded or withdrawn position; and
FIGURE 6 is a view in end elevation of the member shown in FIGURES 4 and 5.
Referring to the drawings there is shown a storage structure for the storage crops from which animals may self-feed such as a silo. The silo includes a concrete foundation or a floor 2, support members 3 in the form of a plurality of circumferentially spaced posts which rest on the outer annular portion of foundation 3 and a hollow cylindrical storage chamber 4 having an open bottom mounted on horizontally extending supports 5. The supports 5 rest on and are secured in place by the vertically extending posts 3. The chamber 4 may be constructed of concrete staves, wood, steel, tile, etc.
A suit-able conedike member 6 which may be in the form of a dodecagon is placed substantially centrally of the foundation and serves to separate and direct the silage outwardly from the mass. Preferably member 6 is provided with a stub center column 7 terminating in a conical end or cap 8 for a purpose hereinafter described. If desired the cap may overhang the column by several inches. It will be noted the column 7 and cap 8 punches through the mass of material above the area of manipulation as hereinafter described. Column 7 prevents the mass from resting on the cone proper, thus preventing the mass from becoming so dense that animals cannot consume it when feeding is initiated.
If desired, a larger diameter conical cap supported by a bearing point at its center may be employed to permit the cap to shift with an unbalance of forces and to adjust itself until balanced by uniform forces. Such construction offers greater support in the center of the silo and permits any jam of material which might occur to release itself.
A plurality of baille members 10 are spaced about .the circumference of the structure adjacent the bottom opening of the storage chamber 4. Baflles 10 are fixed in place and are supported, preferably from support 5, be tween adjacent posts 3.
Each bafile 10 includes a bottom portion 11 and an upper portion 12. Bottom portion 11 cooperates with similar portions of other battles to form a constricted area within the silo extending between the stub center column 7 and portions 11. Portion 12 is inclined down-. ward in the silo so as to direct the mass of silage toward the area of greatest restriction (adjacent portions 11) as Well as to form areas of gradually increasing constriction Within the silo. Sleeves 13 extend through baffles 10 through which rods or pins 14 may be forced within the mass of silage for a purpose hereinafter described.
Baflles 10 may be formed of a rear plate 15 and a front plate 16 having its upper section extending outwardly to the wall of the silo. Reinforcing plates 17 are provided welded to plates 15, 16. The sleeves 13 extend through plates 15, 16 and are welded in place in the structure. The bafiles may be welded to supports 5 if desired.
Considering the operation of the structure, the storage chamber is filled with silage. The spaced bafi'les Ill provide a constructed area within the silo and partially support the mass of silage in place. When the mass'is partially supported by the battles and at regulated intervals permitted to move downward over them, the silage is compressed radially to conform or adjust to the reduced area and circumferentially to conform or adjust to the smaller circumference. a
When the silage is suspended on the peripherally placed bafiles 10 and compressed radially, the mass is free to expand downward only, the middle portion of the mass, the constricted area, fracturing and dropping downward. Such action is encouraged by the unsupported weight of the mass in the middle portion thereof. When the mass *is compressed circumferentially it is also free to expand downward and outward between the baffles 10. Ballooning occurs and ragged radial fracture planes are created; thus silage resting on the bafiles separates into segments for individualmanipulation. As stated above the bafiles are fixed in place and provide only partial support of the mass. Pins 14 provide additional support to keep the mass of silage suspended. It isdesirable in my invention that baffies 10 be designed to. provide maximum, uniformly distributed support and yet not completely support the mass of silage. Since each baifie and pin combination supports a segment of silage, the silageis'subjected to a localized vertical compression. Silage is elastic to some extent so that the mass of silage extends the vertical compressive forces outward horizontally in the approximate shape of a V. This means that material beyond the compressed region or area will attempt to maintain its original condition, resulting in the fracture and separation of silage between the peripheral points of support- The fractures created within the material result from forces of gravity, intermittent vertical compression and horizontal compression thus aiding in the ready manipulation of the silage.
It will be appreciated pins 14 are inserted in the lower sleeves 13 when filling begins. After the silo has been filled to the, elevation of the cap 8 on the stub center column 7, the pins 14, bafiles 10 and column 7 support the silagemass above them. The silage below remains loose and retains its quality if the-base closure is airtight. A suitable plastic layer wrapped around the silo base over the feeding openings and bonded to the metal supports ontop and the concrete foundation creates a suitable airtight seal.
After the silo is opened for self-feeding and the silage within the base has been consumed it will be appreciated the mass of silage is still supported and manipulation is required to control the descent of this material. Pins 14 are removed from lower sleeves 13 removing the support such pins provide. The segmentof silage that was contained vertically between the pin and the bottom edge of the inclined portion IZ'of bafile 10 now expands and is free to drop. Usually, however, it will not drop immediately. Accordingly the pins 14 are then inserted in the upper sleeves 13 and pushed within the mass pushing the segment ofi the baflle and permitting the segment to drop in the feeding space below. The pin is then withdrawn and reinserted in the bottom sleeve to accept a loadagain whenthe silage settles on it. Generally several pins need be employedbefore the silage'slips, past the baflles andcomes to rat on the pins again. The amount of silage dropped and the location of the drop are controlled by the number and location of the pins manipulated.
In FIGURES 4, and 6'1 have shown a modified form of partial support which may be employed in place of the pins 14 previously described. Thereis shown in FIG- URE 4, the rotatable shelf member in supporting position. The shelf member includes a plate member 30 carrying a pipe or pin 31 adapted to support the mass of silage. Plate 30 is pivotally supported at 32' from the structure by brackets 32. An on center restraining arm 33 holds plate 30 in position. Arm 33 is rotatable about pivot 34 supported by brackets 35. A handle (handoperable) 36 is connected to arm 33. When frictional forces are overcome andthe arm is moved on center, the weight on the rotating shelf member moves the arm 33 downward out of contact with the rotatingpin 31, and plate 30 as shown in FIGURES; 'Ihe shelfmember 4 then can rotate and the mass of silage is freed and drops into the feeding area below. Handle 36 attached to arm 33 provides sufiicient leverage to move the arm off center. Preferably, a stop 37 is provided'to assurethat the weight of the mass does not force arm '33 fromits operating position. 7 V
The present invention provides a method of manipulation of silage during storage which permits ready feedingof silage to a position in which it may be reached by the animal feeding thereon.
