JULIUS KAHN, OF DETROIT, MICHIGAN.
JOIST-HANGER.
Specification of Letters Patent.
Patented Aug. 8, 1905 Application iiled October 19, 1904. Serial No. 229,096.
Z0 a w/wm t may concern.-
Be it known that I, JULIUs KAHN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Joist- Hanger, of which the following is a specilication.
Myinvention relates to means for supporting the ends of floor joists, beams, girders, braces, and similar building members; and the object of my improvement is to provide a hanger that shall have the maximum capacity for its weight and that can be constructed at a low cost. I obtain this object by the construction shown in the accompanying drawings, in which- Figure 1 is a side view of one form of my hanger. Fig. 2 is a front view of the same. Figs. 3 to 8, inclusive, are perspective views of various modifications of the same.
Similar reference characters refer to like parts throughout the several views.
Joist-hangers are usually made of cast-iron, in which case they are of great weight, or of long bars of steel that are bent to form hooks to engage the main beams and headers and the stirrups for the joists. In the constructions shown in the drawings each hanger is cold-pressed out of a rectangular sheet of mild steel of the requisite size and thickness. The material will usually be rolled to the right width and thickness and 'sheared off to the requisite lengths. The spike or bolt holes are next punched andthe plate then placed between the dies of a press, where by one movement the requisite form is given to it.
In the usual form of wrought-steel hangers the weakest point is at the angle of the hook, the hangers giving way under a heavy load by bending at that point, throwing all the load on the bolt holding the hook down. At the least opening of the angle of the hook the whole weight is thrown on the very edge of the beam or header, crushing it. In my present invention I have provided additional strength at this corner, which varies with the different forms shown.
In Fig. 1 the stirrup is made up of the horizontal bottom 1 and upright rear portion 2. The bottom is joined to the cross-piece 3, which in turn is connected to the hook-plate 4 by the diagonals 5. This hook or bearingplate and the rear portion of the stirrup are struck up to form an arched portion 6, that adds greatly to the strength of the hook. A spike 7 is shown extending through o ne .edge
of the bearing-plate, a hole being provided on the other side of the arch for a second spike. If desired, a third spike may be driven through the hole 8 into the main beam.
In Fig. 3 the rear portion 11 and the base l2 of the stirrup are the same as in Fig. l. The diagonals 13 are reinforced by the side pieces 14, which extend from the lower crossbar 15 to the rear end of the bearing-plate 16, thus forming two very stiff plate-girders at the angle of the hook. Spike-holes may be provided, if desired, in all of the dierent forms.
In Fig. 4 the side pieces 21 extend over the entire space between the diagonals 22 and the upright 23 and the base 24 of the stirrup.
In Fig. 5 I have shown a hanger suitable for attachment to an I-beam or other upright girder having flat sides. It differs from the structure in Fig.`4, in that the bearing-plate extends vertically. Rivets 29 serve to secure this hanger to the I-beam.
Where beams of great width are to be supported, the structure shown in Fig. 6 will be found to be of value. The rear uprights 3l and bases 32 are connected to the diagonals 33 by the side plates 34. The hooks are stiffened at their angles, as before explained. These hangers are formed in pairs, which are secured to both sides of the beams by the bolts 35.
The Wall-hanger 36 is very similar to the structure of Fig. 3. The rear edge of the bearing-plate 41 is bent up to form a hook 42 to engage the rear of the front row of bricks in a Wall. The diagonals 43 and side plates 44 are formed into arched portions 45 at the angle of the hanger, and so strengthen it greatly, while the great width of the plate 4l givles the hanger a large bearing-surface in the wa In the hanger shown in Fig. 8 the diagonal flanges 5l are bent up to stand vertical at the angle between the bearing-plate 54 and the upright rear portion of the stirrup. ln this manner the uprights 55 are very high and being an extension of the side plate 52 of their respective side form a hanger of great stiffness.
In each form of hanger shown the diagonals extend from the front end of the base of the stirrup to the bearing-plate, and in every case where the supporting-plate is at an angle to the upright plate of the stirrup this angle is supported by other portions of the original plate from which the hanger is formed and rendered of the greatest possible strength.
Many changes and variations in the form of these hangers may be made by those skilled in the art without departing from the spirit of my invention.
Having now explained my improvement, what I claim as my invention, and desire to secure by Letters Patent, is-
1. A pressed joisthanger, comprising a plate of uniform width and thickness bent to form a lower cross-bar, a base-plate, an upright rear portion and a bearing-plate, and a diagonal member integrally connected to the cross-bar and bearing-plate yportions of the bent plate.
2. A pressed joist hanger, comprising a plate of uniform width bent to form a front cross-bar, a base, an upright portion and a rearwardly-extending bearing-plate, and flat diagonal members lying in the same plane extending from the ends of the front edge of the bearing-plate to the ends of said cross-bar and iontegrally connected to said plate and cross- 3. A pressed joist hanger, comprising a plate of uniform width bent to form a base and an upright rear portion, and flat diagonal members lying in the same plane, and integrally connected, one on each side, to the upper edge of the upright rear portion and extending to and integrally connected to each side of the front edge of said base.
4. A hanger, comprising an upright rear portion and a horizontal base connected to said rear portion, a rearwardly-extending bearingplate connected to said upright portion, a cross-bar at the front edge of said base, and diagonal members extending from said bearing-plate to said cross-bar.
5. A pressed joist hanger comprising a plate bent to form a base, an upright rear portion and a rearwardly-extending bearingplate, the material being bulged out at the angle between the upright portionand the bearing-plate to stii'fen said angle, and diagonal members extending from both sides ot' the bearing-plate to both sides ot' thefrontedge of the base and integrally connected thereto.
6. A pressed joist hanger comprising a plate bent to form a cross-bar, a base,anup right rear portion and a rearwardly-extending bearing-plate, ,the material at and on both sides of the angle between the upright portion and the bearing-plate being pressed outward to form a hollow arch to strengthen said angle, and diagonal members extending from both sides of the hearing-plate to the ends of'sa-id cross-bar and integrally connected thereto.
In testimony of which I have signed my name to this specification in the presence of two subscribing witnesses.
JULIUS KAHN.
