Specification of Letters Patent.
Patented June 5, 191?.
Application filed Octoberil, 1916. Serial No. 125,004.
To all whom it may concern:
Be it-known that I, OLEY J. LEAR, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Belts and Processes of Making the Same, of which the following is a specification.
This invention relates to a belt and process of making the same.
The main objections to the present form of laminated belting is the weakness due to splicing orformation of joints, and to the woven form of belt the tendency to stretch. Another objection to belts formed of leather and one especially strong at the present time is the high cost of leather of suitable .quality for this purpose. I
The object of my invention is a belt constructed of cotton yarn or other similar material, and in which joints or splices of any kind throughout the body of the belt are avoided, and in which the material or strand extends along a line parallel to the belt.
edges, thereby distinguishing it from woven structures, thereby practically eliminating stretching of the belt after it has been formed.
With these objects in view I construct the belt as hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which:
Figure 1 is a perspective View of a belt in process of construction.
Fig. 2 is a plan view of the completed belt.
The belts may be of any desired length practical to construct, of any convenient width, and used for any purpose for which they might be adapted Any number of cotton strands may be taken as a unit, and in the drawings I have shown two, the smallest number of strands desirable to use, and I show these strands, 1 brought into the form of a belt, the strands being stitched together in any desired manner. This determines the length of the belt, and is the first unit. The two strands are then continued along a side of the original belt or unit 1, and are stitched thereto, forming a unit which I have designated as 2.
This would form a belt four strands in width. This operation is continued addi: tional units 3 being formed and all extending side by side and being successively stitched in position.
The width of the completed belt will be determined by the number of strands forming a unit, and by the number of units employed.
When the ends of the strands 4 are reached they are secured to the preceding unit as in. Fig. 2.
By this means a belt of uniform strength is formed having no joints or splices in its body portion. I have illustrated the stitching in a conventional manner by dotted lines 6, and it will be understood that I do not desire to be limited to any particular manner of stitching or securing the various strands or units together.
What I claim is:
1. A belt formed of a series of units extended side by side and secured together, each unit being forme f a series of strands also laid side by side, the strands of one unit being continuous with those of adjacent units.
2. A belt formed of a series of units laid side by side, and having their ends secured to their body portions, each unit consisting of at least two strands of fabric, and each unit being secured to its adjacent units.
3. The process of forming a belt comprising uniting ends of two or more strands of yarn or equivalent material to the body portion of said strands, thereby determining, th length of the belt, and then continuing said strands along the sides of the belt so started, stitching them together, until the other ends of the strands are reached and securing said ends to the body portion of the belt at the side opposite the connection of the first mentioned ends.
4c. The process of forming an endless belt which consists in layingstrands side by side and stitching until said belt has reached the desired width, the strands forming the belt being continuous from one side of the belt to the other. 7
In testimony whereof I aflix my signature. OLEY JOSIAH LEAR.
