BEAM CONSTRUCTION.

Specification of Letters Patent. Patented Apr. 19, 1921.

Application filed August 10, 1918. Seriallo. 249,2?7.

To all whom it may concern."

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

This invention relates to beam construotion. One of'the objects thereof is to provide a simple and practical construction of beams possessing strength and durability in a high degree. Another object is to rovide a beam head construction which s all be' light and yet well adapted to meet the hardest conditions of practical use. Another object' is to provide a loom beam head construction in which the several parts ma be individually replaced. Other objects wi 1 be in part obvious and in part pointed out hereinafter. v

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

In the accompanying drawings in which is shown one or more of various possible embodiments of this invention,

Figure 1 is an end View partially broken away in order to show the construction moreclearly; and

Fig. 2 is a section taken substantially on the line 2-2 of Fig. 1. 7

Similar reference charactersrefer to similar parts throughout both views of' the drawings.

Referring now to Fig-Q of the drawings.

there is shown ahead member 10 preferably pressed out of sheet steel and provided wit the desired flange 11 at itsouter edge to stiffen this part. This member 10 is fitted about a shoulder 12 ona heavy collar 13 which in turn is mounted upon the shaft 14. The head is held securely against the end of the barrel 15 by any suitabie detachable means not here shown as such means forms in itself no part of the present invention. The adjacent surface of the head member is preferably provided with an annular recess within which the end of the cylindrical barrel fits, as shown at 15;

Also mounted upon the shoulder 12 is a pulley 16 preferably stamped out of sheet steel which extends outwardly with the head member 10, resting against the same, and thence in a direction parallel to the barrel to form the pulley face 17. This pulley t'er- Inmates in a flange 18 which serves the double purpose of stiffening the edge and holding the belt thereon in place.

A series of rivets 19 pass through the flange 20 of the collar 13 and through both the members 16and 10 as shown inFig. 2 of the drawings, thus securely holdin these parts together. Furthermore, the'p u ley 16 and head member 10 are additionally held together at points farther outward in a radial direction by rivets, as at 21," or otherwise.

' In considerin the action of the device, it is to be note thatthe head construction as a whole, while light, is extremel rigid as its inner portions which would be subject to the greatest bending stress are formed of two thicknesses of sheet metal rigidly held together. Furthermore, if these parts should become bent in use, they are readily straightened as distinguished from the result in a cast head memberin which a crack not only ruins the head but often the yarn wound on the beam. If for any reason one of the parts becomes injured beyond repair, it may be separated from the remaining parts by suitable toolsand replaced. This action can be followed moreover if it is desired to substitute a head or pulley of larger or smaller size. The entire head construction is readily adaptable to replace the heads of beams of the ordinary construction as it requires no special co-acting parts.

. It is to be understood that the term pulley is used broadly throughout to comprehend either a member which may be employed for driving purposes or as is commonly the case in loom beam construction, for retarding purposes, by having a frictional member wrapped about the same.

It will thus be seen that there is provided a construction in which the several objects of this invention are achieved.

As various possible embodiments might be made of the above invention and as various changes might be' made in the em- LAND ASSIGNOR- TO FRANK MOSSBERG bodiment 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. i

I claim as my invention:

1. In beam construction, in combination, a barrel, a beam head, a pulley member provided with an inwardly extending flange secured to theinner portions of said beam head, a shaft, and means mounted upon said shaft and engaging said flange to hold said headagainst the end of said barrel.

2. In beam construction, in combination, a -sheet metal head provided with a central opening, and a sheet metal pulley member having an inwardly extending continuous flange resting against the inner portions of said head substantially down to said opening and secured thereto whereby the inner portions of said head are reinforced by the flange of said pulley.

3. In beam construction, in combination, a barrel, a beam head, a shaft through said barrel, a pulley member provided with a portion shaped to rest against and be secured to said head, and means mounted upon said shaft and holding said head against the end of said pulley member.

4. In beam construction, in combination, a supporting collar provided with a shoulder directed toward the barrel of the beam, and a sheet metal pulley member having at its side away from the beam an outwardly directed flange and at its side toward the beam an inwardly directed flange fitted about said shoulder and secured to said collar.

5. In beam construction, in combination, a supporting collar, and a pair of sheet metal members secured thereto one of which forms the head of the beam and the other of which is shaped to form a pulley member, said sheet metal members resting against oneuanother at their inner portions to form a head of added thickness with respect to the outer portions thereof.

6. In beam construction, in combination, a supporting collar, anda pair of sheet metal members, one of which forms the head of the beam and the other of which is shaped to form a pulley member secured thereto, said sheet metal members resting,

pulley member, a shaft, and means on said shaft holding said head members against the end of said barrel.

In testimony whereof, I have signed my name to this specification this 29th day of July, 1918.

WALTER i. TUTTLE.
