To all whom t may concern:

Be it known that I, ALFRED N. REEVES, a citizen of the United States, residing at Nashua, in the county of Hillsboro, in the State of New Hampshire, have invented a new and useful Improvement in Looms, of

which the following is a specification, refer-k ence being had to the accompanying drawings.

The invention is in looms of the recipro cating batten type. It relates particularly to means intermediate the protector rod and the shuttle binder of the said binder (as a shuttle enters the box) will be imparted to the protective rod dagger and will be relatively increased both as to the speed of, and the distance traveled by, the said dagger, thus rendering it practicable and safe to operate the loom at high speed.

Heretofore it has been most common, so far as I am familiar with the art of weaving, to transmit the movement of the shuttle binder directly to the protector rod, that is to say in such manner that the dagger carried by said rod moves in unison with, and the same distance as, the'binder; the movement of the dagger being so sluggish that, when the loom is speeded up, the end of the dagger occasionally fails to clear the bunter or rubs said bunter and becomes worn and useless in a short time.

- My present invention is designed to overcome this objectionable result by giving an increased throw, and a quicker action, to the dagger.

In order to explain my invention clearly I have provided the annexed drawing which is a perspective view of a portion of a bat- -ten showing particularly the shuttle box and binder, the protector rod and dagger, and the parts connected therewith which relate to my present improvement.

Referring to the drawing the numeral 20 indicates a part of the batte-n of a loom and 21 denotes the shuttle box mounted on, and carried by, said batten. Journaled in bearings 22 on the hatten is the so-called protector rod 23 having secured thereto the dagger 24.

Fulcrumed at 25, at the side of the shuttle box, is the shuttle-binder lever 26, all of the parts thus far specified being of the usual and common constructions in this class of looms.

Secured to one end of the protector rod whereby the movement 23 is an upwardly extending arm 27 whose free end portion ordinarily lies in the path of the end of the shuttle binder 26 and so that, when the shuttle enters the box and forces the end of the binder outward, the binder, in turn, forces the upper end of arm 27 outward and thus rocks the protector rod and lowers or raises the dagger 24, the degree of movement of the free end of the dagger being about the same as that of the end of the binder 26. In my present improved construction, however, I provide novel means between the binder and the arm 27 whereby the limited movement of the binder is relatively increased in the arm 27 and dagger 2li, as I will now describe in detail. Fixedly secured to the batten or shuttle box is a bracket 28 on one side of which is fulcrumed a lever 29 whose, upper end portion engages the shuttle binder 26. Fulcrumed on the bracket 28, at a point below the fulcrum of lever 29, is a lever 30 whose lower end is slotted to receive a pin 31 in the opposing end of the lever 29, the arrangement of the fulcra of levers 29 and 30 being such that a given movement of the free end of lever 29 will be considerably increased at the upper end of the lever 30, which upper end is formed with an offset plate portion 30 which lies behind the free end of the arm 27 already mentioned and it will now be understood that, when a shuttle enters the box 21 and forces the binder 26 outward, the dagger 24 will be simultaneously moved but with an increased throw, and I find in practice that the action of the dagger is quickly responsive to the movement of the binder instead of slow or sluggish as heretofore. This new and valuable result makes it possible and safe to speed up looms of this type so as to increase the daily product, or to increase the number of picks per minute.

In order to hold the protector rod 23 yieldingly in its normal position, I provide the customary spring 32 one end of which is secured to the arm 27, as here shown, the other end of said spring being secured to the bracket 22 or to the batteri.

I wish to call particular attention to the fact that my described improvement may be applied to looms of ordinary construction without making any material changes in such looms.

Having thus described my invention, I

claim as new and wish to secure by Letters i nection at their lower ends, the movement 10 Patentzof the upper end of one lever being con- In a loom, in combination with the shuttrolled by the shuttle-binderfand the move- Y tle binder and protector rod, an arm se. ment of the corresponding end of the other 5 cured to said rod, and means consisting of lever controlling the movement of said arm,

a plurality of levers between the ree end whereby the movement of the binder will 15 of said arm and the binder, said levers be relatively increased when transmitted to being ulcrumed at diierent elevational the said arm. Y points7 and having a slotted and pin con- ALFRED N. REEVES.
