STRUCTURAL SLEEVE roe FOUNDATION sILLs.

Application filed August 29, 1921; Serial .No. 496,440;

T 0 all whom it may concern? Be it known that ROBERT WALKER, a citizen of the United States of America, residing at Dover, in the county of Morris and State of New Jersey, has invented'new and useful improvements in Structural Sleeves for to avoid the necessity of mortising the beams thereinto and at the same time to avoid the waste of timber and the loss of time incident to effecting such joints; and witl'i this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in' the accompanying drawings; wherein Figure 1 is a side view, and Figure 2 is a plan view of a sill joining sleeve constructed in accordance with the invention.

Figure 3 is an end view of the same showing the sill in section.

The device consists essentially of a sleeve.

10 of plate metal, preferably wroughtiron or its equivalent of cross sectional dimensions adapted to receive the extremities of I ad oining sill timbers 11 which are arranged with their ends 1n abutting relation at or about the center of the lengthof the sleeve and are'secured therein by transverse rivets 12 or similar fastening devices serving to prevent relative displacement and reinforce the oint, and carried by this sleeve may be shown respectively at 13 and 14 are illustrated in the drawing with lateral upstanding flanges 13 and 14;, for the reception of the adjacent extremities of timbers 15 and 16 arranged in intersecting planeswith the sills adjacent to the joint. The inner walls 13 and 14 of these chairs or seats are riveted or otherwise fastened as indicated at 17 to the side walls of the sleeve, and

obviously maybe attached thereto at any desired portion of the length thereof according to the plane of intersection of the side timbers, and the latter are secured in the chairs or seatsby rivets 18 Or the equivalents thereof to prevent endwise or upward movement thereof. 7

The use of a joining member such as described while insuring the rigidity of the joints between the sill member and between the extremities of the beams and the sill, avoids the necessity of cutting away or lmortising the sill ends or mortising the intersectingbeams intot-he sills, with the further advantage that the intersecting timbers may be attached either directly opposite the joint between the sill members orat one side or the other thereof according to" the demands of the structurefwithout weakening or affecting thejoint between the sill members or between the beams and the sill members, and without necessitating any complicated cutting of the material.

Not only is the resulting oint equally as strong if not stronger than when a mortise connection is formech but the waste of material incident to the overlapping of the tim hers and the consequent cutting away thereisoaese of is avoided and a large part of the time F occupied in forming the joints is saved.

Having described tlleillVGHlZlOlL what is claimed as newand useful is A steel structural oint COIIJPI'ISlIlg a paralielopiped sleeve which is openfrom end to end, a chair member applied to the side of the sleeve and formed from a sheet of. metal having a bottom portion and side flanges which are spaced from each other. one or more chairs or seats of which two above thebottom portion. said bottom portion andside flanges being provided with inturnedand overlapping inner end flanges,

and securing devices passing through the overlapplng flanges and securing th chair ROBERT WALKER,
