JOHN E. ZIMMERMANN, OF WILLOWGROVE, PENNSYLVANIA, ASSIGNOR TO THE AMERICAN PULLEY COMPANY, A CORPORATION OF PENN- SYLYANIA.
SHEET-METAL JACK-SPOOL.
SPECIFICATION forming part of Letters Patent No. 715,729, dated December 9, 1902.
Application filed February 14, 1902. Serial No- 94,051. (No model.)
To all whom it may concern:
Be it known that I, JOHN E. ZIMMERMANN, of Willowgrove, Montgomery county, State of Pennsylvania, have invented an Improvement in Sheet-Metal J ack-Spools, of which the following is a specification.
My invention has reference to sheet-metal jack-spools; and it consists of certain improvements fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.
The object of my invention is to provide a construction of jack-spool which shall be inexpensive, while at the same time embodying the qualities of indestructibility, lightness, and proof against any condition which would cause injury to the yarn when beingwound on or off the spool.
In carrying out my invention I form the spool of metal, and preferably wholly of sheet and tubular steel, the barrel being clamped to the heads in such a manner as to avoid all interference with the yarn in being wound on and 0d the spool.
My invention also embodies details of construction, all of which will be better understood by reference to the drawings, in which- Figure 1 is a side elevation of a jack-spool embodying my. invention. Fig. 2 is an end elevation of same. Fig. 3 is a sect-ionalelevation of one end of the spool. Fig. 4 is an elevation showing the details of the clamp separated. Fig. 5 is a sectional elevation of one end of a jack-spool, showing a modified form of clamp. Fig. 6 is a sectional view similar to Fig. 3, enlarged. Fig. 7 is an end elevation of the spool-disk, and Fig. 8 is a cross-section on line 8 8 of Fig. 6.
A is the barrel, B B are the heads, and C C are the end journals for supporting the spool. The barrel A is made of light steel tubing, and the heads B B are made of stamped or pressed sheet metal. These heads are circular and have their peripheries beaded, as at J, to give strength and smoothness. The
beads are turned outward, so that the inner faces of the heads are smooth and allow the yarn to run on and off properly. The central portion of the heads is preferably cupped out- Wardly, as at K, and of a diameter corre sponding to the diameter of the barrel A for reasons to be explained hereinafter. The ends of the barrel are flanged inwardly, as at D, and preferably so as to form conical ends which are adapted to the cone-shaped central depressions in the heads constituting the cups K.
E represents clamping bushings fitting within the barrel and placed therein before both ends are flanged, said bushings each carrying a long bolt H, extending through the center of the corresponding head, which is held in place by a nut I, screwed upon the bolt. The projecting ends of these bolts form the journals 0 and are smooth and of slightly less diameter than the body of the bolts. The bushings E each consist of the two parts G p and F, the former being stamped and drawn out of sheet-steel and the latter formed of a short section of steel tubing with one end flanged in to form a conical end 6, or stamped and drawn up from sheet-steel, as in the case of the part G. The conical end e is shaped so as to fit snugly against the inner face of the conical flange D of the barrel A, as shown. It will now be readily understood that these parts F G abut upon each other and are centered within the barrel and constitute a clamp E, which is drawn against the inner face of the flange D of the barrel by the bolt H, and the head B is clamped against the outer face of the flange D by the not I of the said bolt. This construction is simple, inexpensive, and durable. It also permits of dismantling, :when desired, if from any cause the head should be badly damaged and a new head required to be attached. The clamp E acts as a firm support for the bolt and holds it centrally. It thereby gives great rigidity to the extension C as a journal. The manner of joining the barrel and heads presents no obstructions by which the yarn could become caught or broken, and the whole spool is most excellently adapted for the special purpose ofa j ack-spool.
While I have preferred to make the flange D conical and the parts eand K to correspond, I do not limit myself to any special angle for the flange, as the essential feature is simply to enable such flange to be clamped between ICO Lil
the head and an internal clamp through the agency of a bolt, which may, if desired, also act as a journal for supporting the spool.
In place of making the clamp E of stamped or drawn sheet-steel I may form it of a casting, as shown, for example, in Fig. 5, the par ticular shape or construction of this clamp being immaterial to my invention.
While my invention is specially designed as a jack-spool, I wish it to be understood that a spool embodying the above improvements may be used for any purpose for which it may be found adapted.
In many cases the rough usage of the spools requires special strengthening of the disk B, and this I accomplish by forming the disks with radial ribs k, which extend from or near the beaded rim to the cupped center K, as clearly shown in Figs. 6 and 7. By extending the ribs into the cupped portions K the junction makes a specially rigid and strong hub portion. If desired, the disks may be ribbed for strengthening in any other manner; but it is advisable in most cases that the ribs shall project outwardly, so as to be out of contact with the yarn or material wound upon the spool. I would also point out that in the constructions shown in Figs. 3, 4, and 5 the bolt H has an ordinary head, and hence cannot be drawn outward through the clamp E for repair in case of the breakage of the journal 0. To obviate this possible difficulty, I prefer to make the head of the bolts T- shaped by providing their inner ends with lugs h It, as shown in Figs. 6 and 7, and providing the aperture in the clamps E with holes G, having notches g, as shown in Fig. 8. In this manner the bolt maynormally be tightly held in place, and yet by loosening nut I it may be turned and withdrawn for replacing with a new bolt or for repairs.
While I prefer the construction herein set out and shown, as being excellently adapted for the commercial embodiment of my invention, I do not limit myself to the minor details of construction, as they may be modified without departing from the spirit of the in vention.
Having now described my invention, what I claim asnew, and desire to secure by Letters Patent, is
