JOHN FREDRICKSON, OF CHICAGO, ILLINOIS.
JOIST AND GIRDER HANGER.
To all whom it may concern:
Be it known that I, JOHN FREDRICKSON, a citizen of the United States, residing at the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Joist and Girder Hangers, of which the following is a specification.
My invention relates to improvements in joist and girder hangers adapted for use in building construction, the object being to provide a simple and efficient formation of hanger parts whereby a maximum degree of strength with a minimum weight of metal is provided in the hanger.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed, in which.
The invention will be best understood by reference to the accompanying drawing.
Figure 1 is a side elevation of a joist and girder hanger embodying my invention, Fig. 2 is an end elevation of the hanger, and, Fig. f3 is a horizontal section taken on line fc-w of Fig. 2.
The preferred form of construction as illustrated in the accompanying drawing comprises a post 1, a girder 2 and a pair of joists 3. These members are temporarily secured togetherl by means of nails 4 as indicated by dotted lines in the several figures. The girder 2 is supported by means of a metallic hanger 5 having a flat seat 6 on which the end of the girder rests, as illustrated in Fig. 1. Depending from one edge of the seat 6 is a perforated lug 7 which may be secured to the post 1 by means of a lag screw 8 or any other well known securing device. A pair of arms 9 formed integral with the seat 6 project upwardly from the ends thereof in such a manner as to embrace opposite sides of the girder 2, this feature being clearly illustrated in Fig. 2. These arms are curved in such a manner as to project beyond the end of the girder 2 and to embrace opposite sides of the post 1. The free ends of the arms 5 are thus brought into a vertical plane which is offset from the plane of the seat 6 as will be apparent by reference to Fig. 1. Bolt-holes 10 are provided in the free ends of the arms 5, and the portions 11 of said vfree ends through which Specification of Letters Patent.
Application led September 13, 1911.
Patented Mar. 12, 1912.
Serial No. 649,187.
said bolt-holes are passed are raised, as clearly drawn in Fig. 3.
From t-he construction thus far described it is evident that a rigid supporting means is provided for the girder 2, especially after an elongated bolt 12 is passed through the bolt holes 10. In order to support joists 3 a pair of substantiall U-shaped metallic hangers 1B are provi ed. Each of these hangers is provided with a flat seat 14 on which a oist 3 rests and with side fianges 15 to prevent rocking of the joist. The upper ends of the flanges 15 are connected together by means of a tie-head 16 as clearly illustrated in Figs. 1 and 2. Depending from each seat 14 is a joint-lug 17 which is provided with a depressed portion 18 fitting over the raised portion 11 of each free end 5 as illustrated in Fig. 3. In this manner the joistl hangers 13 are maintained in a vertical position after the locking bolt 12 has been positioned as shown in Fig. 2.
A joist and girder' hanger as above set forth is useful in building construction and facilitates the connection of parts similar to those illustrated in the accompanying drawing.
Vhile I have illustrated and described the preferred construction for carrying my invention into effect, the same is capable of variation or modification without departing from the spirit of the invention. I therefore do not wish to be limited to the exact details of construction set forth but desire to avail myself of such variations and modifications as fall within the scope of the appended claim.
Having described my invention what I claim as new and desire' to secure by Letters Patent is:
A metallic girder hanger comprising a flat elongated seat, a perforated lug projecting downward from one edge of said seat, arms disposed at right angles to said seat and projecting upwardly from the ends thereof, said arms having a compound curve such that the free ends thereof lie in a vertical plane offsetfrom said seat, there being bolt-holes in said free ends, joist hangers adapted to be bolted to said free ends of said arms, each joist hanger comprising a seat and flanges extending upwardly therefrom, and :L joint-lug extending In testimony whereof I have signed my downwardly from said last named seat and name to this specification 1n the presence oi having a bolt-hole for registration with a two subscribing witnesses.
bolt-hole in one of said free ends, there be- JOHN FREDRICKSON. ing registering raised and depressed lpor- Vtnesses:
