J. WQH. CAMPBELL. GRAIN BAG.
Patented July 19; 1864.
NITED STATES PATENT Curios.-
IMPROVEMENT IN GRAIN-BAGS.
Specification forming part of Letters Patent No. 13,567, dated July 19,1864.
To all whom it may concern:
Be it known that I, J. W. H. CAMPBELL, of San Francisco, in the State of California, have invented a new and improved method of consfructing bags designed for thestorage and transportation of grain; and I do hereby decare the following to be'a full, clear, and exact description of the same, reference being had in the accompanying drawings, in which the difl'erent figures represent difi'eren t methods of applying my improvements.
The nature of my invention consists, first, inso strengthening the bottom portion of grain-bags by attaehin g additional thicknesses of suitable material thereto, or by increasing the thickness of the cloth at the proper points in weaving the same, as to rend rthe ba much more durable; and, second, ad it of ihe attachment of handles for the purpose f facilitating the handling of them when filledit is a well-known fact that bags used for the storing and transportation of grain invariably wear out first atthe bottom and lower corners, in consequence of standing up when filled, and in'removal being frequently dragged instead of carried. So great is the difl'erence between durability of the bottom and other portions of the bag that it is acommon practice among farmers to cut open the bottom when it gets WOIIlrfllld sew up the mouth of the bag, thus changing end and is excessively severe-a point which will be touched upon and the cause pointed out farther on.
' 1 construct my bags in any of the usual ways, and having provided suitable strips, (which may properly be of the same material as the. bag itself,) they are sewed to the bags across the bottom in such a manner as to project upward on either sidea distance of several inches, or far enough to cover the bottom when the bag is standing filled or being dragged across the floor. The edges of this piece are securely stitched to the sides of the bag, as is shown in Figures 2 and 3, thus doubling or *treblin g the strength, thickness, and durability of that part of the bag; and as the cost of a new bag must be much greater than the cost of the addition of this strengthener, it must appear obvious that be gs provided. with this improvement must ultimately be much the more economical, as one bag so provided will at least last twice'as long as a bag made in the ordinary way.
It has been said that the labor of handling bags of grain is extremely severe. This arises from the fact that a well-filled bag only presents a part which can be readily grasped at one end when the mouth is gathered and tied, and as a bag of grain weighs from one hundred and forty to one hundred and seventy pounds two men are required to work together in handling. them. When the bag can be grasped'by the gathered end, that portion of the labor is not severe, for a man may without difficulty lift one-half of one hundered and seventy pounds, but when it is necessary to grasp the bottom end of the bag, as one or the other must do, the case is materially changed, for no place-can be found for the hands to grasp but the smooth round surface, hard and unyielding. The difliculty of this operation will be fully appreciated by any one who has ever participated in or even seen the operation of handling bags filled with grain or other hard substances.
The corners of the bag form the only part where it is'possiblc to take'hold of it at the bottom, and the sore fingers, stilt muscles, and torn nails of the workmen sufficiently attest the laborious character of this work. The corners being, when filled, in the form of very obtuse cones, must, it is obvious, he of the worst possible form for the hand to grasp. It is to obv iatc this'ditiieulty and to render the labor less severe that I propose to construct my bags with handles, as representedin drawin gs hereunto attached. This result I accomplish. either by stitching all the thicknesses together-in aline marked fin Fig. 2, or by stitching the thicknesses together around the corners, as shown in Fig. 3. A flap, F or G G, is thereby produced, through which I cut holes, as in Figs. 1, 2, and 3. These holes are securely stitched around or their edges otherwise firmly secured, to prevent raveliu g or tearing. v
"If the bag is of large size, a cord may belaid in the edge, as shown in Fig. 3, where the outside piece is turned up for the purpose of showing the said cord. These holes form excellent handles, and are so situated that they may be readily grasped. They will not undnly strain the bag and will not be liable to catch if the bag be drawn or draggedover the floor.
If the material of which the bag is made is V woven thicker at the bottom portion, then the handle may be attached in the manner shown in Fig. 4, the central portion of the added piece being left loose, so that the hand may be inserted between it and thebag, or they'may be made in the same way as described and as shown in Fig. '1, and this method of weaving vthe cloth for making bags I intend to make the subject of a separate application for a patent. v
The importance to be attached to my improvement maybe estimated when it is considered that two men can handle sacks of I grain when handles are attached with about half the labor required when handles are not attached, (this I give as the'judgment of 1a borers who have expressed an opinion upon the subject,) and when it is considered that in the single State of Galit'orniaalone about "2,- 500,000) two and. a half millions of dollars a1 e annually expended for grain sacks, and that these sacks are handled by men over and over again many times before reaching their final destination, in many casesthe costof handling exceeding the. cost of the sack, it will be con-- ceded that a saving of even one-quarter of the cost of handling the immense number of sacks of grain is a matter of no small consequence, to which should be'added also the increased durability of the sacks.
It is obvious that the bag maybe made with the handles, as shown, without the addition of bag constructed as described.
