IMPROVEMENT` IN RAG-MACHINES.

Specification forming part of Letters Patent No. 217,100, dated J nly 1, 1879; application filed May s, 1879.

To all whom it 'may concern:

Be it known that I, THOMAS VALTER HARDING, of the Tower Works, Globe Road, Leeds, in the county of York, Kingdom of Great Britain and Ireland, hackle, gill, and pin manufacturer, have invented new and useful Improvements in Rag-Engines, of which the following is a specication.

My improvements in rag-engines relate to the steelpin coverings of their cylinders. Such coverings have been made in various ways. One usual plan is to make the coverings in wooden segments or lags, into which are driven steel teeth, tapered by forging, and having their shanks square. In some cases teeth with a ground taper and made of round steel have been used; but they are liable to become loose, to fly out in working, and to turn round in the holes when, after the pins have become bent, itis attempted to straighten them, or if their action in workingbe reversed. It has been attempted to obviate these evils by the use of round pins or wires made with nail-heads, or having their roots slightly attened.

Now, my invention has for its object to produce a steel-pin cover for rag-en gine cylinders so constructed that the pins cannot either iiy out orturn round, as aforesaid. For this purpose I cover the cylinder with a case, cover, or lagging of metal in segments, provided with pins ground or tapered at the ends, and made with round parts, bent or curved, as hereinafter described. The ground or tapered ends or prongs of these pills I pass through the thickness of said Case, cover, lagging, o r

l segments, so that said bends bear, rest, or

bed against or between the surfaces of the cylinder-body and case, cover, lagging, or segments, as hereinafter described.

Referring to the accompanying drawings, Figure 1 shows, in section, part of a rag-engine cylinder with my invention. applied to it; and Fig. 2 is a sectional view at right angles to Fig. l.

The cylinder-body c is formed with an annular recess, b, or, in other words, is of larger diameter at its ends c than at its intermediate part, Z.

d is an iron case or cover, in segments, surrounding the cylinder-body a.

c c are round steel pins, ground or tapered at both ends, c* el, bent at e2 into the form of staples, and driven through saidiron case, cover, or segments d, so that the prongs project outwardly, as at el el, and the connecting portions or bends e2 are jammed between the cylinder-body a and the metal case, cover, or segments d, which is, or are, fastened (it may be by screwsf, as shown) to the cylinderbody a.

I `do not, however, limit myself to the use of my improved pins with ground or tapered ends el and round, curved, or bent parts e2, in combination with a metal case, cover, or segments, as they may be used in combination with a case or cover of wood, as shown in Fio. 3, 'where a is the cylinder-body; d, the case or cover, made of wood in segments, (as already practiced and c e are the round steel pins, ground or tapered at both ends, eI c, bent at e2 into the form of staples, and driven through said wooden case or cover d.

The bends e2 are pressed or sunk into the wood d so as to be flush with the inner or back surface thereof 5 or the back of the segment or lag may be grooved to receive the bends e2 ofthe pins.

It is to be remarked that the advantages of my invention may be to a considerable extent realized by the use of halfstaples or pins with curved ends, or bycuttin g the staples in the line A B, or making them in the form of portions of staples, as shown, to the respect ive sides of said line A B, so as to produce a curved part, e2, which will bear, rest, or bed against the surfaces of or between the cylinder-body and the case, cover, or lagging, substantially as and for the purpose specified.

1. As a new article of manufacture, a ragengine-cylinder pin ground or tapered at the ends or end el, and made with a round part, bent or curved, substantially as described, and shown at c2, for the purpose specified.

2. The combination, with a rag-engine-cylinder body, a, and a metallic or other case, cover, or lagging, d, of steel pins e, ground or tapered at the ends or end el, and made with i surfaces ofl or between the cylinder-body a round parts, bent or curved, substantially as described, and shown at e2, the whole constructed, combined, and arranged substantially in manner speeiiied--that is to say, with the ground or tapered ends o1 of said pins protruding through said ease, cover, or lagging d, and their round, bent, or curved parts e2 bearing, resting, or bedding,` against the and the ease, cover, or'lagging d,.all substantially as hereinbefore explained and illustrated.
