Such separators are to which the lower end of the separator-rod is commonly employed. The form of the sep ac adj ustably secured, the cross-shaft arm being arators I do not herein claim, as separators partly broken away to show said supplemenof this form are shown, described and claimed tary arm, showing also means of adjusting the in United States Letters Patent No. 496,186, parts which connect said separator-rod to said granted April 25, 1893, to me. scparator-barto vary the distance between the The separator-bar J is preferably a round 9 5 45 extreme points of the traverse of said separarod slightly flattened on the front or outer tors and the yarn-guides, showing, also said face i, to receive the bent inner end of the yarn-guides; Fig. 2, a vertical section on the shank i of the separator l, and to afford a line 22in Fig. 1, showinga left-side elevation suitable bearing therefor. To the separator of a separator and the devices which support, bar J the separators are secured by means of 50 guide, and renderadjust-able said separators; screws 2' passing through slots 2' in the Fig. 3, a front elevation, and Fig. 4 a side shanks of the separator and into or through the separator-bar J. The separator-bar J is supported in a socket L, (see Figs. 3 and 4,) having upwardly -projecting cars Z Z, the front ears Z being curved outwardly at their lower ends at Z to fit the curved surface of the separator-bar and to prevent the separatorbar from rising in said socket when the separators are turned up vertically from between the spindles in the operation of dofiing. The socket-piece L is also provided with an upward projection Z at the back thereof and with avertical slot Z from the top of said projection Z to a point below the lower end of said projection, and one of the screws i extends entirely through the separator-bar into said slot Z and prevents any endwise movement of the socket L on the separatorbar J. The socket-piece is providednear its lower end with a transverse horizontal slot Z to enable said socket-piece to be attached by means of a bolt Z and nut l to the stoppiece M, said bolt passing through the hole on in said stoppiece, and the slot Z allowing the socket-piece and stop-piece tobe adjusted laterally with respect to each other in an obvious manner. The stop-piece M is provided at its upper end (see Figs. 0 and 10) with a forwardly-projecting and upwardly-curved stop on, against which the shank of the sepa rator strikes when restored from its vertical position to its horizontal operative position, the curvature of the shank on the under side thereof where said shank joins the blade or body of the separator causing the separators in descending to slide forward, drawing the separators J into the curvature Z of the ears I, above described, and preventing said separat0r-bar from being thrown upward in the socket by the weight of the attached separators. The lower part of the stop-piece M is provided with a vertical slot m (see Figs. 1, 2, 9, 10, and 11,) by means of which and by meaps of a stud or (having about midway between its ends an annular collar or drawn against the front face of said stop-piece by means of a nut m turning on the threaded rear end of said stud m against the rear face of said stop-piece) said stop-piece is connected to the separator-rod N, said separatorrod having at its upper end an eye n through which passes said stud m said eye being arranged in front of the collar m and being held against said collar by a split spring-pin on, passing through a hole in the front end of said stud in a well-known manner. The lower end of the separator-rod N is provided with an eye a through which passes another stud 12?, which may be precisely like the stud m above described, said stud n having a collar 01, and a nut or, by means of which collar and nut said stud is secured to the slotted supplementary arm f said stud passing forward through the slot f in said supplementaryarm up to said collar n and the nut 72 being turned up against the front face of said supplementary arm, and said eye a being retained on said stud n back of said collar 0: by a split spring-pin f. The supplementary arm f is provided at its inner end with a hook j, which engages the crosssshaft I and near its outer end with a slot f through which passes the stud f above described, said slot f being of sufficient length to enable the sup plementary arm to be applied to crossshaft arms f of diiferent lengths, and the slotted end of said supplementary arm being retained on said stud by a nut f which turns on the outer threaded end of said stud f and holds said supplementary arm up against a shoulder f with which said stud f is provided, as shown in Fig. 2. Bylocsening the nut a the stud a may be moved in the slot finearer to or farther from the cross-shaft F to vary the length of traverse of the separators. The separator-bar J is guided verti cally by a guide-stand P of the form shown in Figs. 7 and 8. Said stand P is provided with a horizontal slot 13 through which a bolt 9 is passed into the roller-beam A, said slot 13 allowing the guidestand to be adjusted laterally, to avoid the necessity of extreme care in making the hole for the bolt 1'). The guidestand P is provided with two vertical guides 19 13, arranged at such a distance apart as to receive and loosely fit the separator-bar J. The rear guide 1) is provided with a vertical. slot p which extends from the bottom of the guide to the top of the same to receive the projecting rear end of one of the screws and to prevent an endwise movement of the separator-bar J, said last-named screw also acting as a stop and by striking against the front lower end of said slot p holding the separators in a vertical position in the opera tion of doffing. The rear guide p is offset forward at 13 just below the upper end of the slot 19 to enable the separator-bar to be lifted out of said guide-stand P.

The projecting rear ends of the screws 1' which enter the slots p 1 are turned down to the bottoms of their screw-threads to produce less friction on the sides of said slots and to prevent said screws from becoming loose in said slots.

I claim as my invention- 1. The combination of a cross-shaft, a crossshaft arm, a separator-bar, separators, secured thereto, a socket, to receive said separator-bar, a plate, connected to said socket, and laterally adjustable thereon, a separatorrod, jointed to said plate, and a horizontal stud, movable with said cross-shaft arm and entering an eye with which the lower end of said separator-rod is provided, as and for the purpose specified;
