CHARLES A. ALLEN, OF WHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WHITIN MACHINE WORKS, OF W'HITINSVILLE, MASSACHUSETTS, A CORPORATION OF MASSA- SKEWERr-SUPPORT FOR GREELS.

Patented Sept. 7, 1915.

Application filed August 21, 1909. Serial No. 513,957.

To all whom it may concern Be it known that I, CHAnLns A. ALLEN, a citizen of the United States, residing at Whitinsville, in the county of Worcester, State of Massachusetts, have invented certain new and useful Improvements in Skewer-Supports for Creels, of which a full and true specification follows.

This invention is an improvement in the mounting of bobbin skewers in the creels of spinning and like machines, and consists in the provision of concentric step-holding and top-holding means for such skewers, which permits the skewers of an upper deck: of the creel to be mounted in coaxial relation with corresponding skewers of a lower deck. As heretofore mounted the bobbin skewers of the upper and lower decks have been relatively oifset from each other on account of the nature of their supporting devices so that no upper bobbin is directly over any lower bobbin. Such arrangement sacrifices the capacity of the creel and prohibits the use of full bobbins at the ends of the rows or near the upright supports of the creel boards. My invention aims to overcome this objection and other objections in existing creel boards, and to this end comprises a novel device adapted for attachment to any creel board but more particularly to sheet metal creel boards, and provides a suitable foot-step-bearing for an upper skewer as well as a top-holding means for a lower skewer,

both being disposed in substantial coaxial relation to each other, but one being operative above the creel board and the other below it, as will be plain from the following detailed description and the accompanying drawings, of which- Figure 1 is a side elevation of the end of the creel of a spinning frame showing several of the roving bobbins in place; Fig. 2 is an enlarged side elevation of a combined step-and top-holding device embodying this invention; Fig. 3 is a vertical central section of said device; Fig. 4 is a top plan of the same detached from the creel; Figs. 5, 6, 7,.

. and 8 being modified forms of construction,

later explained.

The creel shown in Fig. l by way of illustration of the invention, has three creel-boards marked 1, which are made of flanged sheet-metal plates supported by a number of uprights 2, one only of which is shown, The roving bobbins 3, which are journaled between the three creel boards, supply the machine with roving to be spun into thread, but the spinning mechanism is not herein shown, being well known to those familiar in this art. The roving bobbins are each carried on a skewer 4, which has to be removed and replaced in the creel as often as the roving on any bobbin becomes exhausted, and it is one of the objects of the present invention to provide a skewer holder by which the insertion of the skewers when loaded with a full bobbin will be facilitated.

The combined step-and top-holding skewer support of this invention is most advanta-' geously applied to middle creel boards, wherein it may support the tops of the lower skewers and the bases of the upper skewers as above explained. As shown more clearly in Figs. 2, 3 and 4, the sheet-metal creel board 1 is perforated and the skewer-step 5 is disposed within the perforation so as to be substantially flush with the top surface of the board. A cylindrical tube or sleeve 6 having an interior diameter suiting it to receive the skew-step 5, serves as a holder therefor, being suitably fastened to the creel board concentrically with the perforation therein, so as to hold the step within the perforation. A preferred method of fastening the tubular holder in place is by upsetting it within the skewer-step perforation so that it will be held therein as a bushing with its upper headed end substantially flush with the upper surface of the creel board. By this method of mounting, the holes in the sheet metal creel-board may be left in the rough condition in which they come from the punch and do not require to be smoothed or dressed in order to receive the porcelain step, since the riveted head of the bushing therein will form a recess of proper finish for this purpose.

The holder is extended downwardly below the perforation and the bottom surface of the creel board, and is open at its lower end so as to receive and form a concentric top-holder marked 7 for the top of the lower skewer. The extreme margin of the downward extension 7 is turned backwardly and upwardly against the under side of the board in order to reinforce and safeguard the device against, displacement and dis lodgement when struck by bobbins, but other vmodes of reinforcing the deviceby means of a laterally extended part having a bear- 9 by the top wall 9 of the thimble 8 in Fig. 3.

'. plished, according to the form of invention shown in Figs. 1 to l, by inserting a lining 8 therein in the form of a'thimble with a slightly flared or rounded bottom rim and a top wall marked 9.. The thimble is pressed into the tubular extension 7 and held therein by friction. Its transverse top wall forms an obstruction in the interior of the tubular device, upon which the skewer-step 5 is seated, and which may carry the load of the bobbin, and it also serves as an abutment limiting the upward thrust of inserted skewer-tops and preventing them from dislodging the step. The obstruction thus provided, however, is not required to be a complete closure to the interior of the top holder, but there maybe a restricted opening or hole therein, as shown in Fig. 3, of less diameter than the tip of the skewer, through which the skewer-step can be poked pout when vworn or broken, and as is frequently necessary,

Tn Fig. 5', 1 illustrate a further construction of skewer holder embodying my invention. In this form the tubular step-holder marked 6* is made as a separate part from the top-holder part marked 7", being simply a cup-shapedreceptacle with a hole in its bottom, and firmly wedged inside of the tu- .bular top-holder part with its upper edge flush with the upper edge thereof. parts are upset in the creel board perforation so as to be held therein as in the preceding figures, and the reinforcement of the device provided by the reversely turned flange of the preceding figures is in this form provided by; a flange 10 crimped or otherwise formed on the top-holder tube and bearing againstthe under side of the creel board when riveted in the perforation. The lower open end or orifice of the top holder is somewhatreduced in diameter to provide a fairly snug support for the skewer-top and such reduction inthe orifice leavesv a relatively enlarged. space immediately thereabove which permits skewers to be inserted and removed at somewhat of an angle vand thereby tends to prevent the cramping and the danger of breaking the skewer. The perforated bottom wall of the step-holder" 6 constitutes the same obstruction to upwardly thrust skewers as is formed Fig. 6 illustrates a further skewer support within the present invention, in which the step holder marked 6 fis provided with a conical head adapted to rest upon the beveled, margin of the creel board perforation Both and is exteriorly screw-threaded on its part which projects below the creel-board. The top holder 7 is interiorly screw-threaded and united to the step-holder 6 by screwing it thereon and into. firm abutment against the underside of the creel-board, whereby the necessity of upsetting or riveting the holder when in place in the creel board is eliminated. The edge of the top-holder 7 extends laterally away from the margin of the perforation, bearing against the plate as a reinforcement, and in conjunction with the pressure exerted by the top holder 7" against the underside of the creel board when assembled therewith provides adequate rigidity against accidental displacement.

Fig. 7 shows a still further and simplified form of skewer support. According to this form the step-holder and top-holder are both comprised of one hollow piece 11 which has a reduced neck portion 12 forming the step-holder proper, which is upset as before, within the creel-board perforation, and a laterally extending enlargement 13 immediately beneath the creel board adapted to abut against the under side thereof. The skewer step 5 for this holder is formed to be supported within the neck portion 12 by a head flange, there being no interior stepsupporting ledge shown in this form. The contracted lower orifice of the body 11 forms the top-holder and has a relatively large chamber immediately above it and below the skewer step as in Fig. 5.

The further form shown in Fig. 8 is secured in place in the creel-board perforation, with adequate reinforcement against displacement by means of a connection resembling that of a clenched eyelet. The step-holder 6 serves as the eyelet part, having a number of tongues formed in its lower extremity, some of which are turned inwardly as shown at 15 to form the step-support and interior obstruction above men tioned while the others 1st are turned outwardly and clenched over a washer 16, which clamps the inward flange 17 of the topholder tube 7 between itself and the creel board. The step-holder may have its tongues cut and bent prior to insertion in the top-holder (by inserting it before the top-holder orifice is contracted), so that, attachment to the creel-board may consist in simply upsetting its upper margin as before in the perforation, or the margin of the step-holder can be first headed and the tongues 15 thereafter clenched within the top-holder if desired.

It will be observed that the foregoing several means for supporting skewers require but a single perforation in the creel-board for the base of one skewer and the top of another and that the skewer steps are supported in each instance flush or substantially flush with the top surface of the creelboard, and so that the proper cleansing of the boards is not obstructed.

The skewer-steps may be fastened in place in any suitable manner, as by means of cement or by providing resilient friction producing linings for them, and such skewers may be made of porcelain, glass or of any usual or suitable material.

I claim 1. In a creel, a creel-board having a perforation and a skewer-step therein, a transverse support for said step forming the top wall of a downwardly opening chamber adapted to receive and support the top of a lower skewer, said transverse support being provided with a hole or passageway, forming a communication between said chamber and the step, of suitable shape or size to prevent the ejection of the step by an upwardly thrust skewer.
