(No Model A. F. MOCANN.

LOOM GEAR Patented June 1,1897.

UNlTED STATES PATENT OFFICE.

ANDRElV F. MOCANN, OF FALL RIVER, MASSAOHUSETT S.

LOOM-G EAR.

SPECIFICATION forming part of Letters Patent No. 583,655, dated June 1, 1897.

Application filed February 2, 1897- Serial No. 621,682. Nomodeld To all whom it may concern:

Be it known that I, ANDREW F. MCCANN, of Fall River, in the county of Bristol and State of Massachusetts, have invented. an Improvement in Loom-Gears, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates particularly to loomgears attached to the crank-shaft of looms; and it has for its objects the production of a gear which may be readily replaced when worn or broken, to equalize the wear upon the gear, and to insure safety to the loom attendant.

In the majority of looms as now constructed the fast and loose pulleys are mounted on one end of the crank-shaft and the crank-shaft gear and hand-wheel at the opposite end, the hand-wheel being usually required in order to insure the safety of the operative. Such gears are usually cast in one piece with the hand-wheel and keyed to the shaft with the gear-hub close to the shaft-bearing, the key being driven home from the outside, and when the gear has to be removed it is effected by the aid of a forcing apparatus, the operation usually resulting in the breakage of the hub by forcing it over the key, and the whole casting must be thrown aside. It has been proposed to make the gear and hub detachable, keying the latter to the shaft and securing hub and gear together by bolts; but when;

I the foregoing objections by making the hub,

gear, and hand-Wheel in three separate pieces or castings, securing the gear and hand-wheel together and to the hub by suitable bolts, the

hub alone being keyed to the crank-shaft. In this way the hand-wheel'and gear may be removed from the hub together or separately for any needed repairs, and a guard'is always present for the gear.

' Figure 1 is a rear elevation of a portion of a loom-frame and crank-shaft with my inven- A ring-gearb is provided with aweb 1), ap- 6 5 ertured to snugly fit over the shoulder a of the hub-body, to which it is detachably secured by suitable bolts b I The hand or balance wheel 0 is herein shown as formed on an annular body 0', having at its inn er end an inturned flange 0 which slips over the shoulder a the flat face of the wheelflange c resting against theflange b of the gear.

The bolts b are extended through the adjacent flanges of the gear and wheel into the hub-body, rigidly securing the three parts together to operate as a single casting.

By the construction described a very firm and strong connection is effected between the parts, the hub by its shoulder a providing a common support for the gear and wheel, while the latter effectually guards the gear and prevents accidents to the operative.

As the hub and balance-wheel will under ordinary circumstances last as long as the crank-shaft itself it is only necessary to renew the gear when worn out or to turn it relatively to the hub to present new teeth at the points of greatest wear.

I effect a great saving in repairs, reduce to a minimum the time necessary to replace a gear, usually a matter of several hours, and do away with the use of forcing mechanism, which otherwise must be kept on hand to remove broken or Worn gears.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A hub having an annularly-shouldered body, a separable ring-gear to rest against the body, a hand-wheel provided with an inturned flange to embrace the shoulder of the hub, and bolts to rigidly secure said hub, gear gear having a flange to embrace said shoulder and rest against the hub-body, and a hand-wheel having an inturned flange to embrace the shoulder, said hub, gear and 'wheei being detachably connected by bolts, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ANDREW F. MCCANN.
