PHILIP J. FOLEY, OF CHICAGO, ILLINOIS.

BRACKET FOR RAFTERS.

Application filed July 14, 1911.

To all whom. it may concern:

lieit known that I. lmmr J. FOLEY, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Imn'ovemcnts in Brackets for Rafters, of which the following is a full, clear, and exact specification.

This invention relates to improvements in brackets for rafters, and which is also especially adapted for the sash bars of a reenhouse roof, which have heretofore reuired a plurality of angle plates and bolts or the connection of the rafter with its support. be it the cave or the gutter of the roof.

The prime object of this invention, broadly stated, is to support the rafter or sash bar, as may be, from either the cave or the gutter, in turn supported by means of a post, pillar or column of any construction:

A further object is a bracket simple and cheap of construction which is not only adapted for connecting a beam or sash bar with standard forms of metal beams, such for example as angle and channel beams, but which is self locking thereon, while at the same time the tightening of the lock is increased with increasing weight or pressure of the rafter or sash bars, as may be, and the weight of the glazing and other accessories necessitated by a roof or a sash war construction.

A. still further object of my invention is a have such a self locking bracket so constructed that condensations upon glass or other roofing will be discharged before having time to enter the joints between the glazing or roofing and the sash bars or rafters thereof.

A still further object is a self locking bracket connecting the rafter or sash bar with an cave plate and utter, as may be, and so constructed that tie condensing surface thereof is reduced to a minimum, while at the same time the condensations collected by the sash are dischar ed therefrom entirely free and clear 0 their supporting bracket.

\Vith these ends in view, my invention finds embodiment in certain features of novelty in the construction, combination and-- objects and certain other objects are here- 'nafter attained, all as fully described with eference to the accompanying drawings,

Specification of Letters Patent.

Serial No. 638,590.

and more particularly pointed out in the claims.

In said drawings: Figure 1 illustrates, in detail top plan view, a roof and channel beam gutter in which my invention finds embodiment. Fig. is a detail transverse section through the roof or sash bar with the glazing or rooting supported in its opposite position thereon. Fig. 3 is a detail side elevation of the rafter or sash bar in its operative position on a channel beam "utter in transverse section. Fig.4 is a detail top plan view showing the application of a modified form of a bracket embodyingmy invention connecting a rafter or sash bar with an eaves nlate supported by a post or pillar. Fig. 5 is a side elevation thereof partly in section; and, Fig. 6 is a detail top plan view of a rafter or sash bar and the bracket shown in Fig. 5.

Similar characters of reference indicate the same parts in the several figures of the drawings.

6 indicates a standard form of channel beam forming a gutter supported by a pilla r or post 7, to which the gutter is secured by means of countersunk bolts 8 and nuts 9, but which may be by any other well known and commonly used fastening devices. In practice the channel beam gutter 6 is preferably used as a drain or gutter between duplex roofs, and for which purpose the opposing flanges of the channel cam serve. as a means for supporting the rafters or sash bars of the roof for connecting therewith the self locking bracket 10.

The bracket 10 in practice is preferably of malleable iron, cast. in one piece for purposes hereinafter described, the web ortion 11 of which is quite narrow, as'i lustrated in Fig. 6. the edges of which togcther with the flanges 12 provide a face against which is opposed the end of a rafter or sash bar 13, which rests on a flange 14 projecting inwardly from and forming a part of the bracket, the upper portion of the bracket 10 providing a seat 15 upon which to rest the ends of glazing or other roof covering 16. Latex-ally projecting lugs 17, at each side of the bracket, form an abutment for the glazing or other roof covering, which by an undercut 18 forms an upper hook resting upon and engaging one side flange 19 of: the channel beam. The bracket is also provided at. its outer lower edge with a lug 20 in which is an angular recess 21 adapted to simultaneously embrace the outer and under faces'of the channel beam gutter adjacent thereto, with the result that when the bracket isdriven to place it'will be immovably secured in its operative position without the aid of screws, belts or other fastening devices heretofore necessarily employed for that purpose. It should further be noted that there is an openin between the outer edge of the seat 15 an the lugs 17, which provides for the discharge of condcnsations occurring at that point through the bracket castin and it may also be observed that the iiange 14 of the casting may have the rafter or sash bar secured to it by means of a screw 23 passing through the flange into said rafte or sash bar.

The rafter or sash bar 13 (see Fig. 2) is provided in its sides with. opposing channels 24, 25, for gutters receiving and dischar ing condensations from sai rafter or sash ar onl from its lower end, and which directly fal therefrom owing to the narrowness of the web of the bracket, which narrowness of the bracketat this point also serves to prevent its casting shadows which is important when used as a support for sash bars of agreen house.

In Figs. 4, 5 and .6 is illustrated the adaptation of my invention to the connection of a rafter or sash bar with an eaves plate 26, angular in cross section and preferably of standard form, in turn supported from posts 27 and b the girders 28 connecting a number 0 said osts. For its adaptation to an eave the we member 29 of the bracket 10 is rectangular in form, and provided with a hook 30 at its lower end, and with a. la 31 hearing against the eaves plate 26, an is locked to the eaves by swinging it upwardly instead of as in Fig. 3 having the bracket triangularin form, the hook at the to and the bearing lug at the bottom and Ice in" the bracket to the flange of a trough by a dbwnward swinging movement. In principle, and mode of o eration and result, however, the brackets siown in Figs. 8 and 5 are substantially the same in that the form an end an port for a rafter or sash ar, may be locked to the flange and web of an angle iron, in turn supported by a post, that they are self-locking when driven tightly to place, and tighten as the weight imposed upon them by the rafter or sash bar structure is increased.

Both forms of connectin brackets are preferably made of malleab e iron, for'the reason "that they will yield and bend to pressure, and may therebybe fitted closer and tighter to a channel iron trough or an angle iron eaves plate, and without liability to fracturethan if of cast iron or any other (Ionics of this patent m be obtained for five cents each, 'by' addressing the "Commissioner or Eaten".

metal that will not yield to the force to which they are and may be subjected in securing the brackets to their support.

In conclusion, it should be observed that in boththe brackets of Figs. 3 and 5, their hooks and seats are in ditlering perpendicular planes, so that on engaging their hooks with the angle irons forming either a gutter or an eaves plate, the bracket may be swung to its operative position, in which the lag then bears tightly against the face web and the flange of the angel iron, wlth the result that the bracket is locked and self-locked by its swinging movement on swinging it to its operative position.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. A bracket for connecting a rafter or sash with an angle iron support, provided with an an ular seat adapted to embrac both sides 0 the corner of said angle iron and an opposing hook for simultaneously overlapping the flange of the angle iron, which seat and hook form an integral part of the bracket, whereby a perpetually rigid detachable wedging joint is formed between a bracket and angle iron, substantially as described.

2. A bracket for connecting a rafter or sashwith an angle iron support, having formed integrally therewith an angular seat adapted to embrace both sides of a corner of said angle iron, an op osing hook the inner face of which exten s at an oblique angle to the face of said seat, whereby a perpetually rigid, detachable joint formed )etween an angle iron and a rafter supporting'bracket on first engaging the hoo w th the flange, and then swinging the seat 1nwardly to its outwardly engagement with the corner of the angle iron. the bracket is 8. A bracket of approximately triangular form for connecting a rafter or sash with an angle iron support provided at its apex with a hook adapted to hook over the flange of an an le iron, and an angular seat opposing said liook, which said hook and seat are integral with the bracket whereby the bracket may be swung to a permanently locked position by a wedging engagement with the angle iron and sustained at an oblique angle thereto, substantially as and for the purpose described.

In witness whereof, I have hereunto set m hand and allixed my seal, this 11th day '0 July A. D'. 1911.
