JOISTAND WALL HANGER.

SPECIFICATION forming part of Letters Patent No. 546,147, dated September 10, 1895.

Application tiled May 24. 1895. Serial No. 550,488. (No model.)

To all whom it may concern.-

Be it known that I, VINCENT E. GREGG, a citizen of the United States, residing at Cleveland,in the county of Cluyahoga and State of Qhio, have invented certain new and useful improvements in Joist and all Hangers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in joist and wall hangers, its object being to improve the construction and simplify the manufacture of the hangers; and it consists in the novel construction, arrangement, and combination of parts to elfect such object, as hereinafter fully described, and pointed out in the claim.

In the drawings,Figure l is adiagrarn showing the manner of cutting and bending the blanks to form my improved hanger. Fig. 2 represents the completed hanger in face or Fig. 3 represents the same in' side elevation, and Fig. 4 in rear elevation. Figs. 5, 6, and 7 are top plan views of the hanger, illustrating various slight modifications of structure to adapt the hanger to special uses. Fig. 8 is a diagram showing in side elevation the effects of strain upon a joisthanger and illustrating some of the effects of my improvement in hangers.

Heretofore hangers have been made of various forms of rod or sheet metal and adapted to be secured to the supporting-beam, either by hooking over the top, as in the patent to L. M. Ham, No. 247,050, dated September 13, 1881, or by having a lug on the hanger inserted into a hole bored in the supportingbeam, as in the patent to W. Renschel, dated October 29, 1889, No. 414,169.

In the hangers made of rod an objectionable feature is found in the necessity for notching or recessing the joist or flooring to.

obviated by my invention and construction of hanger, which is made from moderately thin plate or bar metal, and having an equal thick ness and cross-section throughout, as shown, does away withtho necessity for notching or cutting any of the parts in contact with it and presents an equal resistance and strength throughout. 7

Referring to the drawings, 0, represents the step or seat of the hanger; a, the sides or cheeks; b, the Wings or face-webs extending from the front edge or toe of the seat to the top or front edge of the supporting part; c c, the supporting parts turned back at right angles to the back of the cheeks a, which rest against the side of the supportingbeam, and c the downtnrned lugs which engage the supporting-beam, either by fitting down behind it or being driven down into its top, as may be preferred. This construction of hanger has the advantage, among others, that it can be made without waste from ordinarycommercial bar-iron, and does not require the use ot'specially rolled or prepared metal. The bar such, for instance, as two and one-half by three-sixteenths flat baris out into lengths, as indicated by the full lines at ff in Fig. 1, and the blanks are bent along the lines 9 g h h km 711, each bend being a right-angle bend bringing the blank in but three bends into the completed form. (Shown in Figs. 2, 3,and 4.) Should it be deemed necessary in special cases to provide for fastening the hanger to the joist or supporting-beam, or both, a lug d may be struck up from the seat a, which Will enter the joist and hold it in place, and similar lugs e 6 may be struck down from the parts 0 0, so as to enter the supporting-beam and fasten the hanger securely thereto. When the hanger is to be used as a Wall-hanger, the lugs 6 may be increased in number, or preferably the parts 0 0 may be left without the downturned to an equal extent relieves the weight on the back of the seat, as is illustrated in Fig. 8, in which the arrow shows the direction of the strain, the full lines show the normal position of the joist, hanger, and supporting-beam, and the dotted lines indicate the position into which the joist and hanger are brought by the action of load placed upon the joists. This tendency of the hanger to pull away from the supporting-beam at the top is sometimes opposed by bolting the top of the hanger to the beam, which expedient causes increased expense and labor as well as still further weakening the beam, whereas by my improved hanger the load which bears on the toe of the hanger is transmitted through the wings Z) Z) directly to the top of the beam and is at all points resisted by the full section of the hanger, while in most hangers the sectional area of the hanger becomes less and less as the top or point of attachment is neared.

Other advantages of my improved. form of hanger are its light weight as compared with other hangers of equal strength; no punching, driving of spikes, boring or fitting is required; no specially-prepared material is re quired; no waste in manufacture; simplicity of machinery required, owing to all the bends being at right angles; its no usually wide bearing on the girder or supporting-beam distributes the load more uniformly on the latter; the joist bears directly against the girder or supporting-beam from bottom to top and gives no opportunity for the latter to twist, and, finally, it can be applied more quickly than any other form of hanger.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

A joist hanger having a seat for the joist, side-pieces extending therefrom to the supporting parts, and decreasing in width from the seat to the top, supporting wings extend ing from the toe of the seat to the top and increasing in width to an extent proportionate to the decrease in width of the side pieces, and a supporting part in continuation at right angles of each wing and adapted to rest on the supporting beam, substantially as described.

In testimony whereof I hereto atlix my nature in presence of two witnesses.
