Application filed November 1, 1921. Serial No. 512,071.

1 '0 all whom it may concern:

Be it known that I, FRANK Mossnnns, a citizen of the'United States, residing at httleb-oro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements, in Beam Heads, of which the following is a specification.

This invention relates to improvements in the constructing of loom beam heads and the like of sheet metal, and in the method of forming the same, and the object of thls invention is to provide such a head with a friction drum or sheave which is also formed from sheet stock and secured tothe outer face of the head-plate by a welding operation thus providing a head of this character wit-h the maximum strength, the minimum weight and the minimum cost of construction.

v appended claims.

In the accompanying drawings:

Figure 1 is a face view of a loom-beam head of my improved construction.

Figure 2 is a central sectional elevation .through the head.

Figure 8 is a perspective View showing a strip of sheet stock from which a fI'lCtlOIl drum or sheave is formed.

Figure 1 shows this strip of sheet stock as rolled into ring form with its ends abutting and welded together, one edge of the ring being then rolled or turned up to form a flange on the ring, the unturned edge of the-ring being secured to theouter face of the head-plate by a welding operation.

Figure 5 is a modification of the construction of beam head illustrated in Figure 2, showing a different style of central hub welded to the outer face of the head-plate.

I have herein shown and described a construction of beam-head which may be employed for loom beams, spools or other similar articles of manufacture, which head members are formed essentially of a disc having a grooved or channeled member secured to its outer face the same being of a diameter less than that of the face plate thereby providing a sheave or friction drum for the purpose of receiving a friction band or belt to which a tension weight or other tension means may be applied for the purpose of controlling the rotation of the beam as the yarn or warp is drawn from the body portion thereof, and the following is a detailed description of one method by which the same may be constructed 2- -With reference to the drawings, 10 designates the headmember which may be constructed of any suitable material but which is preferably cut from sheet stock such as steel or the like, into disc form. In order to stiffen the outer edge of this disc I roll its periphery outwardly as at 11 thus formmg a coiled or rounded flange.

In this particular construction of loom beam-head it is desired to form the annular groove or channel member 12 of a diameter less than that-of the plate or disc and'to accomplish this in a simple and effective way I cut a strip of sheet stock 13 as illustrated in Figure 3, bend the same int-o ring shape as illustrated in Figure 4, welding together as at 1% their abutting edges. I then roll or turn up the outer edge of this ring to form a flange as at 15 and finally secure the unrolled edge 16 to the outer face of the head-plate by a welding operation which operation is rendered possible by the forming of both the headplate and the sheave of thin sheet stock of a character that adapts itself to a welding operation.

By this construction it will be seen that no rivets are required to fasten the sheave to the face of the plate as rivets in such a case are quite undesirable as when they pass through to the inner face of the head-plate they are apt to work loose and catch and injure the yarn. Therefore by this construction of welding the edge of the friction ring or sheave to the outer face of the plate, the inner face of the plate is left entirely smooth and finished thus doing away with any inner fastenings which the yarn can possibly engage.

In loom beam-heads of this character it is found desirable to provide some means which may be engaged by a driving member for rotating the beam with its sheave and to accomplish this in a simple and effective way I have provided a lug or small plate 17 cut from sheet stock with its outer edge Welded to the inner surface of the sheave member and its side edges welded to the outer face of the head-plate. In this way supported in its position by means of a reinforcing center face plate 20 which engages it and which is preferably secured in position by a Welding operation, its central portion being offset outwardly from the plane of the head-plate to extend over a spacing collar 21 whereby the central hub is firmly supported in its position.

In some other cases 1 provide a central hub 22 as illustrated in Figure 5, the inner edge of which is welded to the outer face of the headplater By my improved method of forming a loom beam-head having a friction drum or sheave of sheet stock the sheave member being of less diameter than that of the head plate and secured to its outer face by a welding process, I am enabled to form such a head of the maximum strength and minimum weight at the minimum expense and in addition to these advantages over the old style heads of this character, I am enabled to meet all the requirements of the heavier and more expensive constructions.

Having thus described one illustrative embodiment of my invention and the best mode known to me for carrying out my method, I desire it to be understood that although specific terms are employed, they; are used in a generic and descriptive sense v; and not for the purpose of limitation, the

scopeof the invention being defined and limited only by the terms of the appended claims.

I claim: 1. A method of forming a loom beanr I head or the like of sheet metal, which consists in providing a main head-plate, punching a hole through its center, forming a bar 2. A method of forming a loom beamhead or the like of sheet metal, which C011? sists in providing a main head, punching a hole through its center, securing a central hub thereto, forming a bar or strip of steel into a ring of a diameter less than that of the head-plate, welding together the ends thereof, rolling one edge of the ring outwardly forming a retaining flange, welding the unrolled edge of the ring to the face of the plate concentric to the center hole.

3. A method of forming a loom beam-head or the like of sheet metal. which consists in providing a main head-plate, punching a hole through its center, attaching a hub about said center hole, forming a bar or strip of steel into a ring of a diameter less than that of the headplate, welding together the ends thereof, welding the edge of the ring to the face of the plate concentric to the center hole, welding a radial driving lug to the face of the main plate at a point intermediate the inner surface of the ring and said hub.

4. In a loom beam-head or the like, a head member comprising a metal disc having its peripheral edge rolled outwardly t stiffen the same, and a friction drum or sheave member constructed of sheet metal in ring form of a diameter less than that of said disc and having one edge turned out wardly with its unturned edge welded to the outer face of said disc, and a central hub' secured to the outer face of said disc.

5. A. method of forming a loom beamhead or the like of sheet metal, which consists in providing a main head-plate, punching a hole through its center, forming a ring of a diameter less than that of the headplate, and welding the edge of the ring to the face of the plate concentric to the center hole whereby the inner working surface .of the head-plate is left smooth and intact.

In testimony whereof I aflix my signature.

FRANK MOSSBERG.
