To all w/wmt't may concern:

Be it known that I, GHARKES A ALLEN, a citizen of the United States, residlng at Llnwood, in the county of 'Worcester, Common wealth of Massachusetts, have invented certain new and useful Improvements in skewer-Step Mountings, of which the following is a full, true, and concise specification.

This invention relates to improvement in the means for mounting and holding porcelain or glass skewer-steps in or upon sheet metal creelboards or creel-rails, and consists in the formation and relation of the parts as hereinafter described, whereby such skewer-steps can be held in place with security under normal conditions but with the capacity for ready removal when necessary or desired.

In the accompanying; drawing forming part hereof, Figure 1 is a transverse vertical section of the creel of a spinning or twisting frame wherein the creel-boards are made of sheet-metal plates or strips of a kind in which this invention is particularly serviceable; Fig. 2 is a central vertical section through one form of mounting for the skewer-step Fig. 3 a top plan thereof; Fig. 1- is a similar section of a modified form for use with a different form of step; and Fig. 5 is a top plan thereof.

The creel shown by Fig. 1 comprises three sheet-metal creel-boards 1, the lowermost of which is mounted on the frame of the ma chine substantially level with the roller beams 2, while the other two are adjustably supported in spaced relation above the lower board by the uprights 3. The skewers 4 are stepped in bearings presently to be described in the two lower creel-boards, while their tops are suitably supported, respectively, in the two uppermost creel-boards, it being understood that the skewers are intended to carry bobbins of yarn or roving and are adapted to revolve freely as the same is drawn off from them by the action of the machine, to be thereupon spun or twisted, as the case may be.

Step-bearings for skewers are commonly made of small pieces of porcelain or glass, or like vitreous material suitably glazed so as to oifer very little resistance to the rotary motion of the skewer base thereon, but as the glaze or polish wears oil, new skewer steps are required to be substituted for the worn ones. The present invention enables such changes to be made with the least delay and inconvenience although the steps are normally held in place with special security.

In the new form of mountingillustrated by Figs. and 3, the step is formed by. a; shallow d1shshaped disk or tablet 5, which is seated in adepression 6 formed by punching or otherwise in the plate of the creelboard. The depression is preferably of suflicient depth to accommodate the height of the step so that the concave bearing in the upper face thereof will lie substantially flush with the top of the plate, and with the special form of step shown, the bottom of the depression may be formed solid or with an opening through the same, as desired. In Fig. 2 the bottom is solid. The shallow step-picce 5 isheld in place and supported against rocking or tilting in its pocket by means of a latch or cover member 7 lying substantially flat on the creel-board plate and overlapping the edge of the step piece so, as to confine the same against removal, but at the same time exposing the concave bearing surface thereof so that the skewer can be placed therein. The said latch memher is attached to the plate so as to be removable from the skewer-seat or depression 6 to permit the removal of the step. In Figs. 2 and 3 the attachment is provided by one or more prongs or ears 8 bent or projecting at right angles thereto and adapted to en gage or snap over the edge or edges of corresponding slots 9 punched in the creel-plate adjacent the depression or to be clenched therein, if preferred. The latch member can be made of thin, flat sheet metal, punched with an aperture slightly smaller than the diameter of the step piece, and as thus formed it will not constitute an ob struction to the cleaning of the creel nor will it collect dirt. It will be observed that the depression Gto accommodate the shallow step 5 can be made by a single pinching or stamping operation and simultaneously with the punching of the slots 9.

In the form of Figs. 1 and 5, the creelplate is formed with a similar depression, but the bottom of the depressed part is punched out, in order to accommodate the body of a cylindrical step-piece 10 which has a head flange 11 adapted to seat in the depression, as shown, substantially flush with the top of the plate. The latch member for this form may be the same as above described, but for illustration of the invention it is attached to the plate by a rivet 12 forming a pivot on which it can be turned to one side to expose the skewer-step depression. A detent prong 13 is formed on the opposite side of the latch to engage a corresponding slot in the creel plate and fasten the latch over the depression so that the skewer base may engage the confined step through the aperture therein.

In respect of the foregoing mountings, it

will be observed that the step-pieces are positively confined in their respective pocke'ts or sockets while being capable of quick removal whennecessary without the aid of special tools of any kind and that, in the case of Figs. 2 and 3 particularly, the na ture of the confining member is such that it can be tightened upon the creel-plate by appropriate bending of the detent prongs, and that this also can be quickly and easily accomplished.

I claim:

1. The combination in acreel, of a metallic creel-plate provided with a recess suited for holding a skewer-step, and a latch movably secured to said plate and normally overlying said recess and the margin of the step contained therein.

2. The combination of a sheet metal creelplate provided with a perforation therethrough, a skewer step of vitreous material in said perforation and a latch device movably secured to said plate and adapted to be moved laterally into retaining engagement with said step to confine the same to said perforation.

3. The combination in a creel, of a metallic creel-plate having a perforation, a skewer step formed to seat on the margin of said perforation and a latch adapted to overlie the margin of said skewer-step.

l. The combination in a creel, of a metallic creel-plate recessed by depressing a portion thereof, a skewer-step seated on said depressed portion and a latch holding said step in the recess.

5. The combination in a creel, of a metallic creel-plate formed to provide a seat for a skewer-step, a latch for confining the step to its seat and a detent means on said latch for removably holding said latch in its stepconfining position.

6. The combination in a creel, of a metallic creel-plate formed to provide a seat for a skewer-step, a latch for said step having one or more fastening prongs for holding it upon said plate.

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

CHARLES A. ALLEN.
