IMPROVEMENT lN BELT-SHIPPING MECHANISMS FOR LOOMS.

Specification forming part of Letters Patent No. 198,202, dated December 18, 1877; application filed November 3, 1877.

To all whom it may concern:

Be it known that I, Lucius J. KNowLEs, of the city and county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Shippers for Power-Looms; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which Figure 1 represents a top or plan view of so much of a loom as is necessary to illustrate my present invention. Fig. 2 represents a side view of the parts shown in Fig. 1; and Fig. 3 represents a top or plan view of a portion of the parts shown in Fig. 1, one of the shipper-handles being shown in section on line A B, Fig. 2.

To enable those skilled in the art to which my invention belongs to make and use the sanlne, I will proceed to describe it more in detai In the drawings, the part marked A represents one side of a loom-frame, to which are secured the bearings B B for the shaft 0, upon the end of which are to be secured, in the usual manner, the tight and loose pulleys.

D is the shipper-rod, to which is secured the shipper-fork E, by means of a set-screw, a. The shipper-rod D passes loosely through a guide-piece, b, said guide-piece being rigidly secured to the side of the loom-frame; and between said guide-piece and the shipper-fork a spiral spring, F, is arranged upon the shipperrod D.

The fiont end of shipper-rod D is hinged to the long arm of a bell-crank or connecting lever, G, pivoted at d to a stand, H, fastened to the side of the loom, while the short arm 6 of the bell-crank is provided with a pin, f, which projects up and passes through a slot, g, provided with a notch or recess, h, in the foot I of the shipper-handle J, said shipper-handle being secured to a rod, K, which passes through under the breast-beam L, so that it can be operated from either side of the loom.

The upper end of shipper-handle J is shown broken off in Fig.2; but it will be understood that it is to have a suitable hand-piece, as shown in Fig. 1, and the opposite end of rod K, on the opposite side of the loom, is also to be provided with a suitable handle, so that shipper-rod D can be operated by means of the slotted foot I from either side of the loom.

When shipper-fork E is to be drawn toward the loom-frame for the purpose of throwing the belt upon the tight pulley, the operative takes hold of shipperhandle J and draws the upper end forward, thereby throwing foot I back, as shown in dotted lines, Fig. 3, and by which operation pin f is forced toward the loom-frame, thereby drawing the long arm 0 of bell-crank or connecting lever Gr forward, together with shipper-rod D, as indicated in dotted lines, Fig. 3; and when the parts are in this position, pin f rests in the recessed or notched portion h of slot 9, and the action of spring F upon shipper-rod D holds the parts in such relative positions until the operative, taking hold of the upper end of handle J, forces it back until pin f has been released from the recessed part h, when the action of spring F throws the shipper-rod D, with its fork E, back into the position shown in full lines, Figs. 1 and 2, thus throwing the belt upon the loose pulley again.

It will be observed that slot 9 is cut at an angle with the side of the loom, so that it acts upon pin f in the form of a cam, thereby rotating or swinging bell-crank or connectinglever Gr upon its pivot (1 until pin f reaches and enters the notched or recessed part h in said slot, when pin f reacts upon the slotted foot I in such a manner as to force and keep it back in the position shown in dotted lines, Fig. 3, until, as before explained, the operative removes, by means of handle J, pin f from the notched or recessed part h of said slot g.

In very narrow looms rod K may be dispensed with, and a projecting stud substituted for supporting shipper-handle J, said stud being properly secured to the loom-frame; and in cases where the belt-shaft G is arranged upon the loom at right angles to the position shown in the drawings, a straight connecting lever, Gr, would be used instead of a bell-crank connecting-lever, since the direction of the motion of shipper-r03. D would be at right andie J, provided with notched and slotted. foot gles to its present motion. I, and connecting-lever G, substantially as Having described my improvements in shipand for the purpose set forth. pets for p0Wer-1ooms,what I claim therein as LUOIUS J. KNOWLES. new and of my invention, and desire to secure Witnesses: I by Letters Patent, is- Tnos. H. DODGE,
