JOHN C. BROOKS, OF PATERSON, NElV JERSEY, ASSIGNOR OF ONE-HALF TO ROBERT H. STERRETT, OF PATERSON, NEXV JERSEY.

NARROW- -WARE LOOM.

SPECIFICATION forming part of Letters Patent No. 704,295, dated July 8, 1902.

Application filed July 9, 1900,

To (tZZ whom, it may concern.-

Be it known that 1, JOHN C. BROOKS, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Narrow-Ware Looms, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to the needle-motion or the mechanism for inserting the loop of weft or filling in looms used for weaving narrow fabrics; and the invention consists in certain improvements in the construction of such mechanism, as hereinafter described and claimed.

Figure 1 of the drawings is a view in elevation, partly broken out, showing the manher of mounting upon the baton or lay of a loom the sleeve which carries the weft-inserting needle. Fig. 2 is a plan viewof a section of the baton or lay, showing my improvements applied thereto.

A post 11 passes through an opening a in the baton A and is secured to the baton by means of screws a. Mounted so as to oscil late freely on this post is a sleeve 0, having at its lower end a hub 19. The lower face of this hub and the corresponding part of the baton are provided with circular grooves for the reception of a ball-bearing 0, whereby an easy motion of the said sleeve is secured. The said hub 19 is provided at the front thereof with radial pins or projections n. Reciprocating longitudinally at the front of the baton is a rack g, which is provided with upright pins 0', adapted to engage the radial pins n, carried by the hub 19.

Reciprocation longitudinally of the rackq by any desired means will give an oscillating movement to the sleeve 0. Attached at the upper end of the sleeve 0 is an arm e, extending a short distance inward or toward the rear of the loom. This arm constitutes the needle of the loom and is provided with devices by means of which the weft-thread is laid in the shed formed in the warps l3. Extending longitudinally of the arm is a vertical slot 8, and in this slot is located a take-up and tension device for the weft-thread, such device consisting of an eye 1;, through which the weft Serial No. 23,283. (No model.)

passes in the manner hereinafter described, and a spring it, connected at one end to the eye 12 and at the other end to the arm or needle cin a recess t, extending from the slot .9 toward the axis of the arm c. The outer end of the arm or needle 6 is provided with a slot in which is pivoted at h a finger j. A spring Z, attached to the arm or needle 6 near its extreme end f, bears upon the finger j beyond the pivotal point thereof and serves to hold the said finger normally in a position approximately parallel to the arm (2. The part c is provided with a duct or guide w, through which is drawn the weft or filling 115 from any suitable source of supply. The finger j is provided with a corresponding open ing i. Through the duct w the weft passes, thence through the eye v of the tension device, and out through opening 2' of the finger 7'. The filling rests against the outer side of the finger j after passing through the eye therein and is by this device properly laid in the shed.

In looms employing needle-motions it is necessary in order to produce perfect fabrics that the loop of thread inserted by the needle be held at one selvage of the fabric, so as to prevent such loop of thread being retracted when once laid, and it is customary to use a selvage-shuttle to lock the looped thread at the selvage opposite from the side of insertion. Attached to the baton A and in position to be struck by the rear end g of the fingerj when the arm or needle is passed through the shed is a stop y. This stop serves to rock the finger j against the force of the spring Z and by that means widens the space between the two parts of the weft-thread forming the loop, so as to facilitate the passage therethrough of the selvage-thread shuttle or other selvage mechanism, (indicated by the letter 0.)

It is obvious that the face of the finger 3' might be provided with a longitudinal groove extending from the eye 2' therein to better guide the weft-thread as the same is laid in the shed.

Having thus described my invention, what I desire to secure by Letters Patent is 1. In a needle-motion for looms, the combination of an oscillating arm or needle having a weft-tension device, of a weft-delivering'finger pivoted at the end of the said arm engaging device, and a spring inclosed within said needle, one end of the spring being socured to the needle and the other to the threadengaging device.

In testimony whereof I have aflixed my signature, in the presence of two attesting witnesses, this 15th day of June, 1900.

JOHN C. BROOKS.
