LOOM.

SPECIFICATION forming part of Letters Patent N 0. 657,914, dated September 18, 1900.

Application filed November 6, 1899. Serial No. 785,998. (No model.)

I?) all whom it may concern.-

Be it known that I, IRVING W. CHANDLER, a citizen of the United States, residing at Burlington, county of Chittenden, State of Vermon t, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

My invention relates to looms which are provided with means for replenishing automatically the weft or filling as maybe necessary from time to time in the operation of the loom, and I have herein shown one embodiment of my invention as applied to a loom which forms the subject matter of United States Patent No. 596,894. In said patent the supplies of filling are supported in a holder, which is moved step by step by or through the partial unwinding of a spring, to bring one after another of the filling-supplies into position to be acted upon by a transferrer, the latter removing the filling-supply from the holder to the shuttle. After each transfer the spring is wound up by means of an arm connected with a pawl-carrier and lifted by engagement with some moving part of the loom, as the lay, the pawl engaging a ratchet, which is shown as moving with the holder, the pawl being drawn back one or more teeth to take a new hold on the ratchet. thereby compressing the spring. The holder for the filling-supplies is shown in said patent as of the Northrop type, which is illustrated in United States Patent No. 529,940, and I make use of such a holder in my present invention. I have so reconstructed the apparatus above mentioned that the movement of the holder is effected in a step-bystep manner by or through the transferrer, and one practical embodiment of my invention is best illustrated without attempting to show all of the forms in which the invention may be embodied. The step-by-step movement of the holder by or through the trans ferrer is the leading feature of my invention, and while I show one mode of effecting such operation I do not limit or restrict myinvention to such mode.

Referring to the accompanying drawings, Figure 1 is a front elevation of a part of a loom, showing a holder with a number of fillapplied thereto.

ing-supplies support-ed by it, forming a filling-replenishing mechanism of the general character shown in the patents referred to, with one form of my invention operatively Fig. 2 is a perspective view of the holder and means for moving it step by step by or through the transferrer; and Fig. 3 is a detail on a larger scale, to be de scribed in the specification.

' The stand a secured to the breast-beam A of the 100m and supporting a stud-like shaft (t ,on which the holder is mounted,said holder comprising two connected plates CL (1, the

ratchet a movable with the holder, the cooperating pawl e on the pawl-carrier (2, shown as an arm fnlcrumed on the stud a and moved in one direction by the spring 6 attached at one end to the stud a", the detent 6 the stud fon the stand a and the pusher or transferrerf, mounted on the studf, having a linger 21 to act against the tip of the bobbin or filling-carrier, are shown in the accompanying drawings substantially as illustrated in Patent No. 596,854. In that-patent the lay efiected the step-by-step movement of the holder, which I have lettered H in Figs. 1 and 2, so that the filling-supplies b were brought one by one into the path of the transferrer 0r pusher to be removed from the holder, the movement of the holder being thus independent of the transferrer. In order to effect the movement of the holder by or through the transferrer, I have shown a lever on, fulcrumed at m on the stand a one end of the lever having a slot m therein to be entered by a pin f on the hub of the transferrer-arm f, so that movement of the latter will rock the lever on its fulcrum. The opposite or inner end of the lever is connected by a preferably-adjustable link m m with a lateral lug 6 on the pawl-carrier e, and by referring to Figs. 1 and 2 the operation of the device will be made clear. When the transferrer f descends to remove a fillingsupply from the holder H, the slotted end of the lever m will be lifted and its other end depressed, so that through the link the pawl carrier 6 will be rocked on its fulcrum toward the front of the loom. The pawl 6 will slip over one or more of the ratchet-teeth and will take fresh hold on the latter, the spring 6 being wound up meanwhile, so that when 111 being threaded into it for adjustment,

while the member .072 is loose in the turnbuckle and headed at m (see Fig. 3,) providing for slip on the return of the transferrer to normal position and preventing bending or buckling.

- My invention is not restricted to the particular embodiment herein shown, as manifestly changes or variations may be made therein without departing from the spirit or scope of my invention.

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

l. A rotatable filling-supply holder, a spring to rotate it, a transferrer to remove the filling-supplies singly from the holder, and means actuated by or through the transferrer towind the spring.

2. A rotatable filling-supply holder, a spring to rotate it, a transferrer to remove the filling-supplies singly from the holder, and means operative on the active movement of the transferrer to wind the spring.

3. A rotatable filling-supply holder,a ratchet rotatable therewith, a pawl-carrier having a pawl to engage the ratchet, a spring fast at one end and connected at its other end with the pawl-carrier, a transferrer to remove the filling-supplies from the holder, and connections between the pawl-carrier and transferrer, to wind the spring by the operation of the transferrer.

4. A filling-feeder to hold a series of fillingcarriers, an actuating -spring to intermittingly move the feeder and bring the fillingcarriers singly into operative position, a transferrer to engage a filling-carrier in operative position and remove it from the feeder, and means controlled by the operation of the transferrer to wind the feeder-actuating spring.

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

IRVING w. CHANDLER.
