BEAM CONSTRUCTION.

Application filed. November 28, 1922. Serial No. 603,753.-

To all whom it may concern:

'Be it known that I, WVALTER I. TUTTLE, a

' citizen of the United States, and a resident stand the conditions of hard and long-continued service and wear. Another object is to provide a construction of the above nature which is thoroughly efficient and reliable in action; another object is to provide a construction of the above nature in which the parts are compactly and securely held in assembled relation and joined in such a manner as to promote ease and convenience in manufacture. Other objects will bein part obvious or in part pointed out hereln after. 4

The invention accordingly consists in the features of construction, combinations of elements and, arrangements of parts as will be exemplified in the structure to be hereinafter set forth and the scope of the application of Which will be indicated in the following claims.

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

Figure 1 is an end elevation of a beam, certain parts being cut away; and

Figure 2 is a partial sectional elevation, the section being taken along the line 22 of Fig. 1 viewed in the direction indicated by the arrows. r

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

Referring now to the drawing indetail and first to Fig. 2, there is shown the barrel member 10 of the beam which is preferably of a hollow wooden type. The construction at: both endsof the beam is substantially the same and therefore one end only is shown. Inside the barrel 10 is 'mounted an abutment 11 preferably of wood, and a metalor wooden spacing block 12 may be secured to the face of'the abutment 11. A shaft 13 extendingaxially throughout the shaft.

length of the barrel passes through the abutment 11 and the spacing block 12, and threaded into the latter is a set-screw 30 adapted to engage the shaft 13 and prevent relative rotation between the barrel and the The shaft 13 extends through the beam head, the construction of which will be later described in detail, and is threaded as n14 to receive a nut 15 which bears against the'head and draws it snugly against the end of the barrel 10. The shaft 13 may be provided with an end portion 16 adapted to rest in suitable trunnions to rotatably support the beam.

Referring now to the construction of the head, there is shown a member 17 against which the end of the barrel 10 abuts and WlllCll preferably comprises a solid circular metal disk having its periphery flanged over as at 18 to provide a belt race. Resting against the metal member 17 is a wooden head member which preferably comprises a plurality of radial arms 19 extending from the center of the head substantially to its perlphery. The arms 19 are preferably evenly spaced and adjacent the center of the'head they are tapered to interfit and,

thus form a substantially solid member.

of the head to its periphery and has itsedge portion 23 flanged over and extending between the ends of the wooden arms 19 and the belt race 18, as shown in Fig. 2. Ex

terior of the metal sheath 22 is a metal member or collar 24 of smaller diameter against which the nut 15 bears. Rivets, as

25, headed against the collar 24, pass through the head and are countersunk and headed in the metal member 17, thus securely and dependably clamping the members of the head in assembled relation. The sheath 22 is preferably of comparatively light metal and, as will be seen, its central portion is securely clamped between the collar 24 and the wooden head member. Adja- 28 and adapted to project into ,Thus the exterior face of the assembled beam head, that is,.the face remote from the barrel 10, presents a smooth even surface. The beam head is particularly strong and sturdy and yet light and flexible, the

wooden reinforcing arms 19 lending the desired strength and rigidity without adding greatly to the weight of the head. At the same time, by the use ofthe metal sheath 22 the wooden members and their securing devices are encased and uneven surfaces and projecting parts which might interfere with the operation of the beam are effectually avoided. V f

Secured to'the inner face of the head is a projecting member 27 which preferably takes the form of a metal cap, as shown, secured to thehead member 17 as by rivets the end of the hollow barrel member 10. The rim 27 of the cup-shapedmember 27 rests against the inner surface of the barrel 10, which surface may be recessed slightly to receive it. Thus, the member 27 serves to transmit the weight'ofthe barrel 10 to the head, which weight would be carried entirely by the shaft 13 without the provision of such a construction. 'VVhen these beams are loaded they are often of great weight and being roughly handled in use there is danger of the shaft 13 becoming bent and out of true due to too great stress being'placed upon it. 'A construction such as that just described, for example, overcomes this difficulty in a simple and effectivev manner by making possiblethe'transmission of a part of the weight of the barrel and-its load directly 'to the head, relieving the strain upon the shaft. The strength of the beam and its adaptability to withstand hard usage are thus greatly enhanced.

' It" will thus be "seen that there is herein provided a. device which embodies the featuresaof-this invention, which device in its actiouattams the various ob]ects of the mvention and v is Well adapted' to meet the conditions of'hard practical use.
