LOOSE-REED MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No; 576,366, dated February 2, 1897.

.Application filed May 21,1896.

To cz/Z whom, it may concern.-

Beit known that we, GEORGE F. HUTCH- INS, residing at Vorcester, in the county of Worcester and State of Massachusetts, and

JAMES NIG-HTINGALE, residing at Summit, in the county of Union and State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in Loose-Reed Motions for Looms, of which the zo following is a specification.

Our invention relates to looms for weaving textile fabrics provided with spring-reeds,an ld more particularly to a supplemental attachment combined with the spring-reed; and the I5 object of our invention is to provide a supplemental mechanism combined with the spring-reed of a loom by means of which the reed will be caused to strike a sharp quick blow to beat up the filling just as the lay 2o reaches its forward position, thus making a fabric of closer and evener texture, particularly silk fabric.

Referring to the drawings, Figure 1 shows a portion of a loom side, one lay-sword, and a sectional view of the breast-beam, lay, and spring reed frame and our supplemental mechanism applied thereto. Fig. 2shows the lay in a more forward position ,with the sprin greed held back preparatory to being` released 3o to beat up the filling. Fig. 3 shows thespringreed released and in its forward position after it has beaten upthe filling. Fig. 4 shows the lay going back and the spring-reed just being disengaged; and Figs. 5 and 6 show, on an 3 5 enlarged scale, perspective details of the two parts of our mechanism.

ln the accompanying drawings, 1 is the loom side 5 2, the breast-beam; 3, the lay, and

l the lay-sword, pivoted at its lower end at 5 and operated by the crank-shaft 6, through the crank-connector 7, in the usual way. The reed S is pivotally supported atits upper side between uprights 9 at each end of the lay 3 by pins to swing in and out at its lower part,

which extends in a recess in the rear upper part of the lay in the usual way. A iiat spring 11, secured at its lower end on the laysword 4, bears at its upper free end against the rear side of the reed 8. A screw 12 extends through the lay and may be turned in Serial No. 592,398. (No model.)

or out to regulate the forward swing of the reed.

All of the above pari-s are of the ordinary construction and operation in the class of looms to which our supplemental mechanism is intended to be applied.

W'e will now describe our mechanism to be combined with the spring-reed.

To the back of the swing-reed frame, near the end thereof, is secureda stand 13, having 6o an arm 13', which extends down below the lay, and is provided with a socket at its end, in which is adj ustablysecured, by a set-screw 14, a contact-piece 15, preferably of hardened steel.

A bracket 1G is secured to the under side of the breast-beam, and in this instance is slotted to receive the rear end of the knock-off. lever or arm 17, which is pivoted to the bracket 16 by a bolt 18 and carries at its front 7o end in a socket therein a finger or contact piece 19, adjustably secured by a set-screw 20 and adapted to engage the contact-piece 15.

A coiled spring 2l extends in a recess in the bracket 16 a-nd bears on the rear end 17 of 75 the knock-off lever 17 back of its pivotal support and acts to raise the front end of said lever 17. A projection 17 on said lever 17 engages with the projection 16" on the bracket 16 andlimits the raisingof saidlever. The en- 8o gagement of the rearend 17 with the bracket 16 limits the downward motion of said lever.

A downwardly-extending proj ection 17 on the lever 17 is adapted to be engaged by a screw 22, adjustable in an ear or lug 23 on 85 the lay-sword 4t and held in its adjusted position by two nuts 24 and 25. The screw 22 acts as a trip to engage the knock-0E lever '17 on the forward movement of the lay and move it down to cause the finger 19 to be disen- 9o gaged from the contact-piece 15 on the swingreed 8, and allow the spring 11 to act to force the reed forward, as shown in Fig.

From the above description, in connection with the drawings, the operation of our supplemental mechanism to operate the springreed will be readily understood by thosev skilled in the art.

As the lay beats up the finger 19 will engage with the contact-piece 15 and hold or reico tard the reed S at its lower part. Just as the lay reaches the limit of its forward movement the screw 22, which is properly adjusted as desired, engages the lever 17 and moves it down to trip or disen gage the linger 19 from the piece 15 on l[he reed S and allow the spring l1 to act to force the lower part of the reed forward and cause it to beat up the filling with a sudden sharp blow.

It will be understood that the details of oonstruction of our supplemental mechanism may be varied, if desired, and may be adapted to be Combined with any spring-reed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In a loom, the combination with a springreed, of mechanism for stopping the forward movement of the reed on the forward motion of the lay, and mechanism for releasing the reed, substantially as shown and described.

2. In a loom provided with a spring-reed, the combination with the reed having an arm thereon extending down below the reed, of a knock-off lever or arm pi votally supported in front of the lay, and provided with a finger adapted to engage the arm on the reed to stop the forward movement of the reed on the for ward motion of the lay, and also provided with a projection adapted to be engaged by a screw or pin on the lay-sword on the forward movement of the lay, to move down said knock-off lever or arm, and release the reed, substantially as shown and described.
