BEAM CONSTRUCTION.

Application filed March 6, 1922. Serial No. 541,277.

To all whom it may concern:

Be it known that I, WALTER I. TU'rTLn, a citizen of the United States, and a resident of Providence, in the county of Providence and State of Rhode Island, have invented an Improvement in Beam Construction, of which the following is a specification.

This invention relates to construction of warp beams and the like.

One of the objects thereof is to provide apparatus of the above nature of strong and durable construction. Another object is to provide a construction of the above nature which is light and thereby efficient in action, yet well adapted to meet-the conditions of hardest, practical use. Another object is to provide a construction of the above nature employing wooden members with proper metal reinforcement to add strength and rigidity where they are most needed. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts as will be exemplified in the structure hereinafter described and the scope of the application of which will be indicated in the following claims. l

In the accompanying drawing in which is shown one of the various possible embodiments of this invention,

Figure 1 is an end elevation of a warp beam;- and Figure 2 is a transverse sectional view along the line 22 of Fig. 1 with certain parts cut away.

Similar reference characters refer to simi lar parts in both views of the drawing.

Referring now to the drawing in detail, there is shown in section in Fig. 2 the end construction of a warp beam, it being understood that both ends are identical, and one end only being shown in order to avoid encumbering the drawing. The barrel member or cylinder of the beam is shown at 10 and may be of any desired specific structure, such as that of a hollow wooden type built up of a number of sectors. A shaft 12 reaches the entire longitudinal extent of barrel 1O passing'substantially through its center and also extends a substantial distance beyond either end of barrel 10. Inside barrel 10 and adjacent its end there is preferably mounted a wooden abutment 11 secured to the inside surface of barrel 10 and provided with an opening at its center through which shaft 12 passes. Likewise mounted inside barrel 10 there is shown a clutch member 13 preferably secured to the face of abutment 11 as by means of screws 29. Mating with clutch member 13 is a clutch member 14 which will be hereinafter described.

Referring now to the head of the beam, there is shown resting against the end of barrel 10 a metal head member 15 which is preferably a solid metal disk of substantially the diameter of the head. Snugly contacting with the surface of disk 15 is shown a head member comprising preferably a plurality of built-up wooden elements as 16, 17 and 18. Each of these elements comprises a plurality of wooden members resting edge to edge to form a disk of diameter slightly less than that of disk 15. The three wooden disks are preferably so assembled that the grain of the wood in disks 16 and 18 is substantially at right angles to the grain in disk 17. The individual elements of disks 16, 17 and 18 may besecured together by glue or by other suitable means. The periphery of metal disk 15 is preferably flanged to extend over the peripheries of wooden disks 16, 17 and 18, and this flange extends downwardly toward the axis of the disks and then upwardly to form a groove '19 extending completely around the periphery of the head. Groove 19 thus provides a belt race through which the beam is driven. There is prefen ably inserted between the flange forming belt race 19 and the wooden head members a resilient filler 20, for instance of gutta percha or rawhide.

Resting against the outer surface of wooden disk 18 are shown a pluralityof radially extending metal arms 21 which are preferably bent inwardly at their outer ends to support belt race 19 and are tapered to interfit about shaft 12 at the center of the head as shown in Fig. 1. A plurality of rivets 22 connect each of arms 21 to disk 15 and upon being headed into position, securely and dependably clamp the three wooden elements therebetween. Rivets 22 are preferably countersunk in arms 21 and in disk 15 to avoid projectin parts which might interfere with the operation of the beam. It will be seen that a head structure built up in this manner e'modies the lightness and consequent flexibility which is essential in beam construction and that the same is yet dependably rein-forced where reinforcement is most needed to insure a strong and substantial structure.

The complete head thus built up as above described is provided with a bore 23 at its center through which shaft 12 passes.

Shaft 12 is threaded as at 25 to receive a nut 26 (omitted in '1 ig. 1), 'andthe end 28 is adapted to rest rotatably in suitable trunnions.

Referring now to clutch member 14 before mentionech'it is shownas being guided into clutch member 13 by shaft '12 passing therethrough. Clutch member 14 preferably contacts with the surface of disk 15 and is provided with a pair of lugs 27 registering with openings in disk 15 and slightly entering'wooden head member 16. Thus, as nut 26 is threaded on to sh aft 12,'the head moves along shaft 12 and head member 15 forces clutch member 12% into engagement with clutch member 13 and in this manner the head and barrel members are easily assembled and a positive driving connection is made'therebetween. As described above, the beam is driven through the head member by meansof belt race 19. The driving force is transmitted from the :head through the clutch 14-13 to barrel member 10.

It will thus be seen that there is herein provided an apparatus which embodiesthe Various features of the invention, which apparatus in its action attains'the various obj ects of the invention and is well adaptedto meet the requirements of hard, practical use.

As many possible embodiments might "be madeof the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
