CHAIN LINK. APPLICATION FILED D50. 26 1905.

Application filed December 26,1905. Seriallilo. 293,266.

To all whom it may concern:

Be it known that I, Gnonsn J. MEYER, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Chain- Links; and I do hereby declare that the following is a i ull, clear, and exact description thereof.

The object of my invention is to provide a simple and economical link lor drive-chains or the like, the component parts of which constitute two members so arranged as to reduce iric tion and wear to a minimum and th ereby'prox' entstretching, which is common in thechainlinks of the standard types, owing to the inequality of wcaring surfaccs oi the link members, the link being also particularly designed so as to provide for the application of anti-friction rollers thereto; said invention consists in certain peculiarities of construction and combination of parts as hereinafter set forthwith reference to g the accompanying drawings and subsequently claimed.

In the drawings: Figure 1 represents an elevation of a fragment of a chain embodying the various features of my invention, and one of joints thereof, as shown, is equipped with an anti-friction roller, said view being also partly broken away and in section to better illustrate the details of construction; Fig. 2, a plan view of the same with parts broken away and psrtsin section to better illustrate the details; Fig. 3, a detail plan view partly in section, of one link assembled; Fig. 4, a perspective view of the separatedlnembers of a link, and Fig. 5, a detail section of another form of securing the jointed link-members together.

Referring by letter to the drawings, A indicates a strap-member, the ends oi, which are formed with integral rightangle male and female pintlcs B, C, the male pintle B of which, for onv cnience in casting and strength may be cored, while the female pintle C is cored to fit and receive the male pintle B of the adjacent strap. A when the chain is assembled. Each strap A is provided with a retaining strapl) which has openings a, b, at its ends arranged to fit over shouldered ends 0, (i, of the pintles B, Q, respectively.

In assembling a chain of the above described'memhers, the male pintle B of each successive strap A is fitted into the cored opening of the female pintle G of the preceding strsp A. The retaining strap D is then fitted over the shoulder c of pintle B and shoulder d of pintle C, in whichposition said strap D is secured 'by upsetting the end oithe shouldered portion c of male pintle B, as shown in the first three figures of the drawings. I The other end. or said strap is held in place upon the shouldered portion of the female pintle C by the succeeding retaining strap 1);Wilich overlaps the end oi the first named strap and is secured by upsetting, as previously 7 described. In place of confining the retaining straps D Specification. of Letters Patent.

Patented Aug. s,

by upsetting the ends oi the shoulders c, in some in stances, it is desirable to utilize a cotter-pin c, which as readily disconnected and assembled without the use of tools, or the same result may be obtained by passing a bolt through the cored openingof the male pintle, and

fasteningthe bolt in place by a nut in threaded connection therewith.

As shown in Fig. 1 and 2 of the drawings, the construction of my link is such that the rollers E may readily be applied to the link-joint, it necessary, by utilizing the exterior circumference of the female stud f), upon which the rollers may be mounted.

In practice, it is usual to couple the link-members of a chain by loose pins or studs, which are prevente'd from turning in said links by suitable lugs or keys, such construction, owing to continuous oscillative strain upon the pins will, in time, cause looseness'and consequent wear and stretch between t e link couplings.

With my device the above mentioned defects are overcome by reason of the straps being formed with integral male and female pintles fitted one within the other and extending the entire widtl between the parallel strap members constitute a link, which construe tion causes till the oscillation to take place between the nested studs, which owing to their b'roadbearing-surfaces, reduce the wear at the jointsto a minimum, it. being understood that the retaining straps, which are fitted over the link studs have absolutely no motion upon the latter.

From the foregoing description and especial reference to Fig. 5 of the drawings, it will readily be understood that link-members carrying the integral male and female pintles are telescopically jointed so that they nest one within the other, and thereby form bearings the full width between the parallel straps in contmdis tinction to joints of chain-links having loose pintles or parallel straps, wherein the bearings pfsaid straps are of unequal width.

I claim:

1. A drive-chain composed of a succession of straps liuving alternate male and female pintles, the male plntle of one strap being arranged to receive the feinale pintle ofthe next strap, and retaining straps arranged to fit over said ,i

male and female plntles, whereby the latter are held in link connectiori.

2. drive-chain composed of a series of straps, having alternate male and female pintles, the male pintle of one strap being arranged to fit the female pintles of the next strap, suti-frlction rollers mounted upon the female plnties, and means for holding said rollers in position thereon,

3. A chain having a series of joints each comprising n strap provided with an lnteg'ral-temale plntle; a strapjnro vlded with an integral male'pintle' fitted into the 1 9mm,

pintle of the first named strap, othgr straps fittd over the nmle-and female pinflos forming parallel members in connection with the s traps aforesaid, and a fastening device for the'straps in connection with the male pintle.

5 4. chain having a seriesof joints. each comprising a strap p1'o\"ided with an integral female pintle, a roller mounted lumn the pintlu, a strap provided with an integral makprutlc inimgugvment with the female pintie 0f the m sc mum-d strap, otl u-r straps having apertured ends fitted 1O m'ur the fnmahand ma'lc pintlespf the first named st'raps aaapm set my hand at Milwaukee in the county of Milwaukee and State of Wiscomain in the presence of two witnesses. 15
