UNITED STATES PATENT "OFFICE. I

DANIEL J. GREEN, OF FALL RIVER, ASSIGNOR TO G-EORGE DRAPER & SONS, OF HOPEDALE, MASSACHUSETTS.

SEPARATOR FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 459,894, dated September 22, 1891.

Application filed February 6, 1891. Serial No. 380,492. (No model.)

To all whom it may concern:

Be it known that I, DANIEL J. GREEN, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Separators for Ring Spinning Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Ring-spinning frames are now commonly provided with separators or blades to stand between adjacent bobbins or spindles above the ring-rail, and various means have been employed for actuating these separators. The separators, as herein shown, are connected to a carryingbar of usual construction, it having-suitable pivots, the bar having co-operating with it suitable backwardlyextended arms, upon which are mounted adjustable counterbalancing-weights, which nearly but not entirely counterbalance the weight of the separator-blades which are extended across the ring-rail, the latter in its upward movement striking the separator-blades and elevating them.

This invention has for its object to provide means whereby the separator-blades may be readily lifted whenever the bobbins are to be doffed, the ring-rail at such time being well down. In accordance with my invention, therefore, I have joined the bar carrying the separator-blades with the usual guide-board by means of a connection, (herein shown as a chain,) so that when the guide-board is lifted it will automatically lift, through the connection, the separator-blades.

Figure 1 in partial section shows a suflicient portion of a ring-spinning frame to enable my invention to be understood. Fig. 2 is a partial front elevation thereof, and Fig. 3 a section in the line 00.

The frame-work A, the rail A, upon which rests the usual spindle-supports B for the usual sleeve-whirl spindles 0, having bobbins D, and the separator-blades E on rods ace, forming the carrier-bar, to which the said blades are secured by screws a, the backwardly-extended ears I), having pivots to rest in bearings on the stands 1), depending from the roller-beam (Z, the arms 6, shown as connected to the ears b, and the cou nterbalancingweights f, the hinged guide-board g, and the stand or are and may be all substantially as common in ring-spinning frames. In accordance with my invention I have added to these old and well-known parts a connection h, shown as a chain, the upper end of which is joined with the guide-board the junction in this instance being shown as made by a hook it, the lower end of the said connection being in turn attached to the separator-carrier bar, or it may be to a separator of whatever construction, the attachment, as represented, being made by a hook, which, after the connection has been passed from above under the lower rod a, is hooked over the upper rod a, as shown best in full lines in Figs. 1 and 2.

When the bobbins are to be doffed,the op erator, by engaging the hand-piece m on the guide-board, lifts the said guide-board into the dotted-line position, Fig.1, until the hook m, pivoted upon the roller-stand m engages a projection m which hook thus acts to hold up the guide-board. Lifting the guide-board as represented also lifts the rod to which the separators are attached, placing the said separators in the dotted-line position, Fig. 1, so that the bobbins may be doffed without interfering with the separators. The lowering of the guide-board enables the separators, which are slightly heavier than the counterbalancing-weights, (one ormore of which may be used, according to number of separatorblades,) to fall into working position.

I claim 1. In a ring-spinning frame, a ring-rail, a series of spindles, a pivoted or hinged guideboard, and a separator-carrying bar provided with a series of separators, the said bar being located below the guide-board, combined with connections whereby the lifting of the guideboard automatically effects the lifting of the separators preparatory to doffing, substantially as set forth.

2. In a ring-spinning frame, a spindle, a ring-rail, a counterbalanced separator-carrying bar located between the ring-rail and the tops of the spindle or bobbin carried thereby, and a series of separators, combined with a hinged or pivoted guide-board and with a connecting device between the said guide-bar and the separators, whereby the lifting of the guide-board lifts the separators and places them in position for doifing, substantialiy as described.

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

DANIEL J. GREEN.
