APPARATUS FOR HANDLING MATERIALS.
Application filed March 21, 1924 Serial No. 700,823.
' This invention aims to provide improved apparatus for handling materials, primarily though not exclusively useful in drying operations.
In the drawings, which illustrate a. preferred form of one. embodiment of my invention Figure 1 is a perspective view of the preferred form of material handling apparatus showing a truck carrying a plurality of superimposed frames; V
Fig. 2 is a perspective view of the bottom of one corner of a preferred form of a frame;
Fig. 3 is a perspective view of the parts shown in Fig. 2, as viewed from above the frame;
Fig. &' is a section through the corners of two frames, showing their relation when one frame is stacked upon the other; and
Fig. 5 is a section on the line 55 of Fig. 4-, showing the relation of the foot on the upper frame to the top of the corner brace of the lower frame.
Referring to the drawings and to the preferred form of my'invention selected for illustrative purposes, I have shown a number of :frames piled one upon the other and spaced apart to provide between the frames when stacked, spaces for the material and, for drying operations, to permit free circulation of air to the material on the frames. These frames are preferably, as illustrated, piledupon a truck or frame having rollers thereon so that the whole apparatus may be moved about conveniently from place to place. 7
My invention is particularly useful as a drying apparatus for drying gelatine, glue, shellac and the like, but is not limited to such use, as it may be used for a variety of other purposes.
The preferred form of frame illustrated is not only very strong, because of a highly desirable corner brace construction, but is very sanitary, as is necessary for drying gelatine or other food stuffs, and is well adapted for stacking, and for transportation when stacked, each corner being held in place relative to those'underlying and overlying it, so that the frames cannot shift and upset during transportation by truck or otherwise.
T 1e preferred form of frame illustrated includes four wooden side pieces joined together at the corners by lap or halved joints, as best illustrated in Figs. 3 and 4, each lap or halved joint fitting closely. This type of joint is particularly sanitary because it presents a smooth unbroken surface at the inside of the frame, as is best shown in Fig. 2. The outer corners of the wood are preferably sawn off to provide a flattened face, for purposes hereinafter more fully described.
A wire mesh is fastened to the side pieces and stretched across the intervening opening to support the substance to be dried, at the same time permitting a maximum amount of exposure of the substance to the air.
The corners illustrated are fastened together by bolts passing through corner brackets which hold the frame rigid, protect it, prevent separation of the joints and at the same time provide spacing means for spacing stacked frames apart and preventing shifting of stacked frames relative to each other during transportation. The preferred form ofcorner bracket illustrated includes a top plate 2, a bottom plate 3 and a foot or spacer l.
The top plate 2 is formed of relatively thin sheet metal, generally rectangular and overlying a portion of each of the wooden pieces 5 and 6, but presenting ears laterally engaging the wooden pieces. Two of these ears? and 8 are bent down against the inner surfaces of the wooden pieces Sand '6, while a third ear 9 is bent down against or clenched against the flattened face 10 at the outer corner of the wooden frame. Thus the ear 9 not only protects the exposed corner of the wooden frame, but exerts a substantial pressure opposed to the ears 7 and 8, thereby reinforcing and relieving the holding bolts 11. the case, the ears, or some of them, are clenched by being hammered after assembly of the corner brackets with the frame, the wooden pieces are strongly urged toward one another and a peculiarly strong and rigid joint is provided.
The bottom plate 3 may be identical with the top plate 2. s
The preferred form of foot or spacer 4 presents a downwardly extending leg, preferably as illustrated U-shaped in cross-section, the bottom side of the U facing the inner corner of the frame, and may advantageously be held in place by the bolts. 11, 11, engaging bosses 13, 14 exterior to the U-shaped leg and a web 15. interior-1y of the Where, as is preferably foot. The heads of the bolts 11 projecting above the top plate 2, constitute a preferred form of locating means for engagement with the foot of the superimposed corner, to prevent any slippage of the latter during transportation of the frames.
Thus, as illustrated in Figs. 4 and 5, the foot 4 rests upon the top plate of the frame below and the heads of the bolts 11 provide suitable stops to prevent shift-ing of the frame above relative to the frame below, thereby preventing the drying frames from becoming upset when they are moved on their truck over rough floors and the like. For some purposes, the bottom plate 3 and the foot 4 may be considered collectively to constitute a spacing means.
The type of corner construction described is particularly sanitary and the parts thereof are easily accessible for washing. The corners are strongly held together and there can be no opening of the joints because of the cooperation between the ears and the bolts. The cars 9, 9 also provide a protection for the corner of the wooden frame, thereby preventing damaging due to rough handling, accidental dropping or the like.
While I have shown and described one illustrative embodiment of a preferred form of my invention, it will be understood that I have done so for purposes of clarification and not for purposes of limitation, and that various changes including alteration. omission, and particularly combinations of individual parts may be made without departing from the scope of my invention, which is best described in the following claims.
1. In drying apparatus, the combination of frames spaced apart by spacing members located at each corner of said frame and cooperating with, triangularly arranged abutments located "at each corner of said farms to prevent relative shifting of said frames.
2. A frame for drying apparatus including spacing members secured to one face of said frame adjacent the corners thereof and a plurality of triangularly arranged stops located at the opposite face of said frame for cooperation with the spacing members of a similar frame, thereby to position said frame relative to a similar frame.
3. A sanitary frame for drying apparatus presenting a continuous unbroken face at the inside thereof, means for holding the corners of said frame together and for pro viding abutments for cooperation with spacing means provided on a similar frame to prevent shifting of one frame relative to the other.
f.
