METALLIC CREEL.

Specification of Letters Patent.

Application filed September '7, 1912.

Patented July 21, 1914. Serial No. 719,071.

To all whom it may concern:

Be it known that I, VViLLIAM O. ALDRICH, a citizen of the United States, residing in hitinsville, \Yorcester county, hilassachusetts, have invented certain new and useful Improvements in the Manufacture of Metallic Creels, of which the following is a full, true, and concise specification.

This invention relates to improved means for mounting porcelain or similar skewersteps in the metallic creel-plates of spinning and twisting machines, and provides a novel construction for this purpose wherein the holders for the skewer-steps can be made and assembled in the creel-plates with the least expense of time and labor, as more fully explained below, forming suitable sockets, securely interlocked with the creel-plate, into which the steps may be placed and held in any suitable manner.

In the drawings forming a part hereof, Figure l is a transverse section of a spinning frame creel of which the creel boards are formed by sheet metal plates, the skewers and bobbins being shown in position between them; Fig. 2 is a full size vertical section of a porcelain skewer-step mounted n one of the creel-plate perforations; Fig. 3 is a similar view of the same parts disassembled; Fig. 4 is a bottom plan view of the holder of Figs. 2 and 3; and Fig. 5 is a modified form, showing an inversion of the holding fingers.

The creel taken for illustration is formed of three creel-plates, each marked 1, and made of sheet metal. The lowermost plate is carried on the main frame of the machine in about the level of the roller beams 2, while the two upper plates are carried on uprights 3, being preferably adjustable thereon so that the vertical distance between the plates can be accommodated to the height of the skewers 4. The latter are journaled 1n upright positions between the plates and form rotary supports upon which the bobbins 5 are placed. The bases of the skewers are stepped on the two lower plates, in bearings or skewer-steps made of glazed porcelain or similar hard or polished material so that the skewers can rotate with the greatest freedom as the yarn is drawn off the bobbins. Their upper ends are suitably held in holes or bushings provided for that purpose in the two upper plates. The bearings or skewersteps are desirably mounted so that their concaved tops are about flush with the top surface of the creel-plate, the latter bein correspondingly perforated, so that they present the least obstruction to the cleansing of the creel, and the step-holders involving the present invention are particularly adapted to this purpose although they may be used or formed otherwise if desired.

The improved step holder consists of a tubular member 6 made of thin sheet metal with its upper part bent or turned at right angles to its barrel-shaped body forming a rim-flange 6 which is adapted to seat upon the margin of the perforation in the creelplate and support the body within and projecting below the perforation. The bottom of the body is closed or partially closed by an interior ledge or shelf 6" which forms a seat upon which the skewer-step 7 placed in r the holder, may rest. The bottom ledge 6 is so formed that an opening is left, herein termed an ejector-hole, through which a suitable instrument may be introduced to eject the step. The side wall of the tubular barrel of the step-holder is slitted at one or more points around its circumference, four in the case shown, to form one or more fingers or tabs which are intended to be bent outwardly underneath the margin of the creel-plate perforation, as shown in the drawings, so that together with the rimflange (5 they will serve to interlock the holder with the perforation in a positive manner, preventing its removal in either direction. In the form illustrated by Fig. 5 the fingers, there marked 6 are cut so that they bend from a point near the top of the tubular barrel and are intended to be bent or curled upwardly toward or against the plate; in Figs. 2, 3 and at, the fingers 6 bend from a point near the bottom and are bent outwardly when made so that when the holder is thrust into the perforation, they spring or snap over the edge thereof into the interlocking position, the fingers in this instance constituting spring prongs which automatically form a positive interlocking connection.

The perforations in the creel-plates are ordinarily and most conveniently formed by punching, and in such case the bur or rough edge left by the punching tool does not have to be dressed or smoothed down when used with holders such as above described, since the edge will in any event be covered and concealed by the rim-flange and the connection effected by the fingers is independent of, and quite indifferent to, the condition of the punch-cut edge of the perforation. The mounting for the step has, thus, a specially neat appearance though produced with economy of labor, both of which are primary objects of this invention. The step-holders are placed in the creel-plate perforations, as they come from the punching machine and whether automatically or manually interlocked therewith as above explained, are immediately ready to receive the skewersteps, the latter being dropped or placed in them and held in place by means of putty or in any other way that may be found suitable. The support thus provided for the skewer is afforded by the rim-flange of the holder which is of ample strength to prevent its passing through the perforation when loaded or knocked, and when the step requires renewal it may be ejected from the holder without removing the latter, in the manner above explained. The holder can also be removed, if desired, by squeezing the fingers together so that they will pass through the creel-plate perforation.

I claim:

1. In a creel, a perforated metallic creelplate and tubular step-holders therein having rim flanges adapted to seat on the margins of the perforations of said plate and each having one or more fingers suitably disposed thereon to engage the under side of said margins,

2. The combination in a metallic creel, of means for mountin the skewer steps therein comprising a tubular skewer-step holder supported in a perforation in the creel-plate, a. supporting ledge in the bottom of said holder forming a seat for the step and having an ejector hole, and one or more fingers or prongs adapted for interlocking said holder wi h and within the perforation.

3. The combination of the creel plate With recesses or perforations therein and means for holding a skewer step, comprising a tubular member, means on said member for positively and automatically interlocking with said recesses or perforations by the insertion of the member into said recess, and a skewer step seated in said member and independent of the said interlocking means.

4:. In a creel, in combination, a metallic creel-plate having a perforation, a stepholder within the same and one or more spring fingers adapted for positively interlocking said holder with the said creel-plate by the insertion of the former in the perforation thereof, and a skewer-step supported in said holder.

In a creel, in combination, a metallic creel-plate having a perforation, a stepholder within said perforation and provided with means adapted for positively interlocking with said creel-plate by the insertion of the holder in the perforation thereof, and a skewer-step supported in said holder independent of said locking means.

6. In a cred, a sheet-1nctal plate forming a creel-l'nau'd or rail and provided with a perforation, in combination with a tubular member having a flange adapted to seat on the margin of said perforation and one or more spdng fingers adapted to spring over and interlock with the under side of the margin of said perforation when thrust therein, and a skewer-step seated in said member.

7. As a means for mounting skewer-steps in metallic creelqilates, a tubular member of thin sheet metal havii'ig its upper part formed as a rim flange adapted to seat on the m: rgin of a creel-plate perforation and its tubular body or barrel portion formed with a bottom ledge or wall adapted to form a seat for the skewer-step and having outwardly bent fingers cut from the sides of said barrel portion, said fingers and rim flange being relatively positioned on the barrel portion to embrace the margin of the creel-plate perforation between them.

8. As a means for mounting skewer-steps in metallic creel-plates, a tubular member of thin sheet metal having an outwardly bent upper portion constituting a rim-flange adapted lo seat on the margin of a creelplate perforation with the body or barrel of said member projecting below the creelplate, the lower end of said member being formed with an interior supporting seat for the ske .ver-step contained therein and having an ejector hole adjacent said seat, in combination with outwardly bent fingers on said tulfmlar member adapted to engage with the under side of the creel-plate.

9. In a creel, a perforated metallic creelplate, a step holder adapted for insertion in perforation thereof, and formed of a tubular barrel portion with integral fingers out in the side wall thereof and bent laterally whereby the ends of said fingers form positive retaining means for said holder within its perforation.

In testimony whereof, I have signed this specification in the presence of two Witnesses.
