JOHN LEE AND JAMES LEE, OF HEPPERHOLME, COUNTY OF YORK,
ENGLAND.
MACHINE-BELTING.
SPECIFICATION forming part of Letters Patent No. 352,548, dated November .16, 1886. Application led March 27, 1886. Serial No. 196,763. (No model.) Patented in England September 2, 1884, No. 11,873.
To all whom, t may concern:
Be it known that we, JOHN LEE and JAMES f LEE, both of Hepperholme, in the county oi' April 28, 1885,) of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature. i
The object of this invention is the manufacture of link belting of leather which will conform to the crowning of the pulleys on which it is run. The links of the belting, which are of leather or other suitable substance-as, for instance, of india-rubber fabric, or of rawhide, fulled or otherwise-are stamped out with the requisite holes for the pins,and theselinks are shaped somewhat like' the links of some forms of lag-chain. These links are put together like the links of a lag-chain, each pair of links projecting .in one direction having between them a, link projecting in the Other direction, and through the holes in the links is passed a pin of metal with a head at one end, and the other end provided with a washer, on which the pin is riveted up 5 or the pin may have a washer at each end and be riveted up at each end. Such a belt as this would, it will be seen, have no flexibility from side to side, and would not conform to the perphery of the pulley,which it is desirable for a belt to conform to, and a width of belt of, say, six thicknesses of leather would be about as great a width as could be conveniently used lin such a form. This would give only quite a narrow belt,or,if the belt be made much wider, would require edge flanges upon the pulley, which is not a desirable construction. We therefore divide the width of the belt into two or more sections, each one of which has its pins quite independent of the pins in each of -the others, and we make between these sectional widths of belt flexible joints, either of Aleys upon which itis placed.
In the drawings, Figure 1" shows a'section of link belting upon the rim of a pulley, which "link belting is not made in independent sections hinged -together longitudinally. Fig, 1
-shows link belting jointed together longitudinally upon a pulley, thejoint being of leather and placed with the hinge part next the pulley. Fig. 2 shows a similar piece of belting upon a pulley with the joint placed the other side up. We have found, however, by experience, that where the hinge is of leather the continuous part of the hinge should preferably be placed next the pulley. Fig. 3 shows a similar view of jointed belting where there is a metallic hinge between the 'two sections. Fig. 3 shows a plan' of the metallic links detached. Figs. 4 and 5 are plans of the belting shown in Figs. 1 and 2, respectively. Fig. 6 is a side view of-the belting. Fig. 7 is an end elevation of. the link belting upon a small pulley. Figs. 8 and 9 are plans of the metallic joints. p
Like letters represent like parts in all the gures.
A are the links of the belting,which may be of leather, wood, canvas, compressed paper, cotton, or what is known as rubber belting, or other suitable material, which are stamped out with rounded ends, in the center of which -is a suitable hole for the pins B, which unite them, and on which they hinge. Through these holes the pins B are passed. The pins may be headed at one end, as shown at C, and riveted up at the other on a washer, D 5 or both ends may have the washers and be riveted up. Ribbons or sections of these linked belts are then fastened together side by side by swivels,
links, or joints E, of metal, leather, or other` suitable material, and as many widths are put together as are required to conform to the shape of the pulley. For instance,if the pulley is simply crowned at the center, as it-would be if two frusta of a cone were placed butt to butt, only one joint would be necessary to run upon the crown of the pulley, whereas if the pulley were of a curved surface and quite wide it would be desirable to have several of ICO these longitudinal joints. By means of these joints these linked belts will conform to the pulley and always ride upon it properly.
1f desirable7 the joints may be of metal,and in that case the adjacent ends of the pins in the adjacent ribbons of belting would project somewhat and be linked together by rings orl by threading wire through holes or securing them together in any desirable or suitable way, so as to form a joint or hinge between the two parts of the belting.
It is also obvious that thin U shaped pieces of sheet metal could be used in .the same way that the leather is used7 as shown in Figs. 1 and 2. The ends of these belts are secured together by ordinary rivets, such as are used in the permanent joints, or by nuts and bolts.
By these improvements these link belts will conform accurately to the periphery of the pulleys, and as it is the tendency of belts to run upon the crown of the pulley there will be no pull upon the joints between the ribbons of the belt having a tendency to separate them.
It will be seen that by this form of belt the waste leather can be utilized, and that a very flexible and .strong belt can` be made of comparatively moderate cost,the flexibility allowing excessive changes of speed between the driving and driven pulley without the loss in a stiff belt which arises from the necessity of bending the belt in running around the smaller linked belting, united together from side to` side at even distances apart by iiexible joints E, substantially as described.
