BAR-NARD L. OLDS, OF ST. ALBANS, VERMONT.

LINK FOR HORSE-POWERS.

SPECIFICATION forming part of Letters Patent No. 250,957, dated December 13, 1881.

Application filed September 13, 1681. (No model.)

To all whom it may concern:

Be it known that I, BARNARD L. ()Lns, of

-St. Albans, Franklin county, Vermont, have invented a new and useful Improvement in Links for HorsePowers, of which the following is a specification.

My invention relates to the means by which thelags are secured to the jointed links of the endless treadsin horse-powers; and it consists in loops or stirrups forming part of the links and engaging slotted lags, by which arrangement 1 am enabled to use lags of uniform construction and avoid the use of bolts.

In the accompanying drawings, Figure 1 is an inverted plan view of a number of thelinks and the lags connected thereto. Fig. 2 is a side view of the same; and Figs. 3 and 4 are cross-sections, respectively, on thelines 00m and 3 y of Fig. 2.

Similar letters of reference indicate correspondin g parts.

A A are the links, formed of cast-iron, and

having the wrought-iron caps a, that form loops 7 at the ends for the joint-pins b, as usual. B B are the wooden lags, attached to the links A by loops or stirrups c. The loops or stirrups c, by which the links and lags are connected, are preferably malleable iron, and connect rigidly by their ends to the links. They are attached by being placed in the molds in which the links are cast. The lags are formed at their ends with crossmort-ises cl and longitudinal mortises 0, into which the loops enter, so that the ends of the lags are firmly held, and the loops are also covered and protected by the lag. The lags attached to the links, as shown, are held as rigidly as by bolts, and there can be no endwise movement. To obtain the offsetting of the links required to joint them, as seen in Fig. 1, the alternate link has only to be reversed to bring its loop at the 0pposite side, as illustrated by the two positions shown in Figs. 3 and 4.. The lags need no alteration to effect this, and therefore can be got out uniformly, instead of requiring bolt-holes in different positions, as is the case when bolts are used.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. The horse-power link, provided with a rigid loop or stirrup, c, for connection of the wooden lag, substantially as shown and described.

2. The combination of the link A, provided with loop a, and the lag B, provided with mortises that receive the loop, sfibstantially as shown and described.
