UNITED STATES PATENT OFFICE.
CHARLES 'D. FULLER, OF KALAMAZOO, MICHIGAN.
BELT-FASTENING.
SPECIFICATION forming part of Letters Patent No. 499,880, dated June 20, 1893.
Application filed May 31, 1892. Serial No. 435,109. (No model.) 7
T0 on whom it may concern.-
Be it known that I, CHARLES D. FULLER, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented new and useful Improvements in Belt-Fastenings, of which.
the following is a specification, reference being had to the accompanying drawings.
This invention relates to belt fastenings or connections, and it has for its object, to provide an article of this character, which by simple variations of its form and manner of adjusting, will be more univerally applicable to all conditions of both new, and nearly worn out belting, and also to provide an article of extreme cheapness and durability.
With these ends in View, the said invention consists in certain details of construction and fastenings on the under side, with the loops passing through the belt. Fig. 3 is a plan view showing the loops of unequal length as shown in Fig. 6, in use. Fig. 4, a plan view, shows its application to a torn corner of a belt. Fig. 5 is a detail view of the cable and loops as used for a single fastening. Fig. 6 is a detail view of the central cable, with loops of unequal length for a double fastening.
Like letters are used to indicate like parts in the several figures.
Referring to the drawings, A is two wires twisted around each other in regular coils, and having loops 0 and D thrown out at intervals; these loops are equidistant from each other and located on either side of the main cable A, formed by the union of the two wires. I usually locate these loops about one-half inch apart, as practical tests prove this to be very satisfactory, but do not of course limit myself to any particular distance.
In operation, I use a gage punch, which forms the holes at distances corresponding with that of the loops from each other; the ends of the belt E on the side coming next the pulley are slightly chamfered; the right number of loops are cut off and are inserted in each hole in each end of the belt to be joined together. A wireB, of suflicient strength is then threaded through the loops 0, which now project from the outside of the belt E;'the ends are slightlybent to prevent slipping and the fastening is complete; the entire tensile strain of the belt pull being distributed evenly across the back of the belt by the binding wire B, and not on the leather only, immediately in front of each loop.
I make no claim whatever upon the binding wire, or the distribution of the belt pull,
as before mentioned. This method has long been common to almost innumerable varieties of belt hooks, links, wire connections, &c. Having thoroughly tried all I have ever been able to find, and noting their defects, my sole aim has been to supply a connection which would be of extreme cheapness, that could be used until worn out, which could be readily applied, and which unlike any other Wire fastening, would never pull out at the ends next the edges of the belt, or require enough extra length to return, or relace back toward the center of the belt. I have found by practical test, on a large number of my own belts, that the extreme difficulty of holding any kind of wire fastening at the edges of the belt under a hard pull, orsudden strain, furnishes an excellent reason for the fact, that almost none of such are in general use. I have completely overcome this difficulty by the strength of the wrap of the wires around each other, and tests have shown that under great strain the wires will break beforeuntwisting. It should also be noted, that should this fastening break at any point, after long wear, I still have as good a fastening left as if composed of single links. A specialpoint of advantage will also, be found as follows:-All the loops on the right hand side of the central cable are formed of one wire, and those on the left from another. By taking hold of a loop on each side it is seen, that they can be readily rocked back and forth sidewise after the manner of a hinge. Ordinarily in use this does not occur,
but in case of sudden strain,accident or running over very small pulleys, the extreme suppleness and pliability of the joints is most valuable, and peculiar only to this fastening- In Fig. 4,1 show a valuable application peculiar to my fastening. It is a thing of almost hourly occurrence on many machines where the belt travel is very rapid and the pulleys perhaps too small, for the belt to run 01?, when going into a heavy cut, or the belt is a little too slack; almost invariably the joint sufiers worst, and acorner is sometimes torn out; it is undesirable to splice in a short piece, and it is frequently impracticable to cut off enough to secure a new hold; by cutting out the torn corner as shown, an extra set of links are quickly applied and the joint is as good as ever.
Fig. 3 shows the application of the form shown in Fig. 6 where I employ alternately a long loop D,and a short loop 0, to accomplish precisely the same result as where a double sewed lace leather joint is used. The great utility of this form can be readily seen when a canvas, rubber, old rawhide, or common leather belt is used, where from long-use and gradual absorption of lubricating oils; the belt has become. so weak that it is almost impossible to make a joint that willnot keep tearing out. Such belts will in many places do long service. This form of my device, as applied in Fig. 3 is entirely successful and will formaperfect joint, which is impossible to tear out .as long as the belt can be made to run.
Fig. 2 shows the belt E lying next to the rim of a pulley G. It will be observed that thecentral cable A does not touch the pulley,
thus avoiding wear. The manner and direction in-which the loops pass through the belt are also shown inthis figure.
Having described my invention, what I claim, and desire to secure by Letters Patent,
around each other in the form of a cable, said cable being provided with loops which are thrown out at intervals along the same; the said loops being formed from the wires composing the cable, and arranged on nearly or quite opposite sides of the same, and adapted when in use to extend upwardly and after passing through holes in the belt, to have their ends at an angle to the plane of the belt, in order to receive the binding wires on the opposite side, substantiallyas described.
2. In a belt fastening for unitingthe two ends ofa'belt, loops or links, formed at regular intervals by elongations or side extensions of two wires twisted around each other in the form of a cable, in combination with binding wires which passthrough the ends of the-loops or links, after said loops or links have been sufficiently inserted through the holes in the belt to receive the Wires on the opposite side thereof, substautially'as described.
