To all 'aU/rom 'it may concern:
lie it known that l, Demi lflnUsrnnvnLn, a citizen of the United States, and a resident' of llull, in the county of Sioux and State oflowa, have invented a new and improved biuspension liafter and Support, of which the following is a full, clear, and exact description.
The present invention relates to new and useful improvements in building appliances and hardware, and it pertains more particu lai-ly to means for bracing the joints of the rafters of hip roofs.
lit is one of the primary objects of the invention to provide means by which the rafters of a hip roof may besecured` together `at their joints without the use of nails or similar fastenings, except to prevent relative movement of the members at the joint.`
it is a further object of the invention to provide means by `which the joint may be tightened from time to time as coniilitions require.
lt is a further object of the invention to so construct a device of this character that it .is applicable to hip roofs regardless of the angle ofthe rafters.
lit is a still further object ofthe invention to so construct a device of this charzuxter as to render the same adjustable to angles of rafters of varying` degrees.
lWith the above and other objects in view, reference had to the accompanying drawings, in whichlligure 1 is a side elevation of the 'joint of the rafters of a hip roof showing the irnproved device and its method of application in actual practice. i
Fig. 2 is a vertical sectional View taken on the line 2-2 of Fig. 1, and showing the device in rear elevation, a portion of one of the members of the device being broken away.
.Referring more particularly to the drawings, the reference character 5 designates the vertical rafter, and (i designates the horizontal rafter of a hip roof. lit is to be under* stood that the roof supported. by these rafters and that there are a sutlicient number thereof to provide :i proper support for the roof.
Secured to the reiter 5 upon opposite sides thereof, by means of a bolt or the like i", are straps S, :1nd said straps 8 are adapt-ed to extend inwardly of the rafter in a siibstantialliT horizontal plane.
Secured to each of the rafters 6 bv means of arbeit 9 or the like, are oppositelywdisposed depemling` stra-ps 10, and said straps 10 depend adjacent their corresponding strap 2% and have their free end lying` in pixtiqiosition tothe inner free end of their respective free strap 8, as more clearly shown in lfig. 1. Extending through the free ends of the straps 8 and 10 is asingle bolt 12, and surrounding` said bolt 12 is a tubular sleeve 13, by means of which the straps S and 10 are prevented from buckling' or bending to, such a degree vthat tliej,v would slide alongthe bolt 12 in either direction.4
Suiiniiinli1i,g the sleeve 13 is a linlr 1li, and pivotally connected in said linlr 14, is a screwsthreaded eye bolt 15, a nut 16 having; engagement with the threaded end 17 of said eye bolt 15. The reference character 2() designates a rigid angular member, and in use two of these members are employed. Each of these member-sis provided in the ree ends oi'- its legs, with aA series of openngs 21, and said openings are adapted lto eceive bolts 22, by means of which the rigid angular members are secured to the rafters and l. 'lhcse angular members are connected at their apexes by a transversely extending); rigid member 23. The angular niembers 2() and the transverse rigid inember 2? are preferably` formed of anele iron and the rigid member .iis secured to the angular members by means of bolts or the like The transverse rigid member 23 is adapted to receiveV the threaded end of the eye bolt 15 as indicated by the reference character 3() in Fig. l, and the nut 1G is adapted to engage the transverse rigid memA ber in order to tighten the eye bolt 15.
The reference character 31 designates a strap or brace which is secured in position by the heretofore mentioned bolts 22, and it will be noted from Fig. 1 that said strap or brace Bl embraces the straps 8 and l), and prevents bending` thereof when the device is being positioned.
rilhe device functions in the following manner:
rlhe members S and 10 are secured in position by means of their bolts i' and 9, re spectively, after which the bolt 12 and the sleeve 13 are positioned with respect to these members 8 and 10. After this has been done, the angular members 2O are positioned and the eye bolt is passed through the rigid transverse member 23, after `which the nut 16 is threaded upon the threaded end 17 of the eye bolt 15 and the eye bolt 15 is pla-ced under tension. As the eye bolt 15 is placed under tension, the strain exerted will cause the joint of the rafters 5 and 6 to assume the proper position and said rafters 5 and,6 Will be maintained in proper position to support the roof. Simultaneously with the placing of the angular members 20, the straps or braces 31 are positioned to overlap the members 8 and 10, as shown in Fig. 1, and prevent their bending or buckling under the strain exerted by the eye bolt.
From the foregoing it is apparent that the present device provides means for supporting and sustaining the rafters of hip roofs Without employing driven fastenings, such as nails, and cumbersome vertical braces as is the common practice. Furthermore, the improved device permits of the tightening of the rafter joints from time to time as occasion may require, and provides a means vvhich is adaptable for use with hip roofs of various degrees of angle.
1. In combina-tion With the rafters of a hip roof, a plurality of members rigidly secured to said rafters and extending inwardly thereof, rigid means connecting said members, angular members pivotally secured to the rafters, and tension means connecting the firstunentioned members with the rigid angular members, as and for the purpose set forth.
2. In combination With the rafters of a hip roof, a plurality of inwardly-projecting members arranged in triangular form, said members being pivotally secured to the rafters, rigid means connecting said members, a plurality of oppositely disposed angular members pivotally connected to the rafters, a rigid member connecting said angular members, and tension means connected to the first-mentioned members and to the triangular members, as and for the purpose set forth.
3. A brace for the rafters of hip roofs, said brace comprising a plurality of members secured to the rafters of the roof in triangular relation, rigid means connecting said menibers, angular members connected to the rafters of the roof, angularly disposed braces connected to the angular members and overlying the first-mentioned members, rigid means connecting` the angular members, and tension means connected to the first-mentioned members and the rigid means connecting the angularI members, as and for the purpose set forth.
t. A device of the character described comprising in combination with angularly disposed rafters, a plurality of straps secured to said rafters on opposite sides thereof, said straps being arranged at substantially right angles one to the other, rigid right-angular members secured upon opposite sides of the rafters, tension means connecting the rigid right-angular members with the straps, and braces connected to the rigid right-angular members and overlying said straps, as and for the purpose set forth.
5. A device of the character described comprising a brace for angularly disposed rafters comprising a plurality of straps secured to said rafters on. opposite sides thereof, said straps being arrangedv at an angle one to the other, rigid rightangular members secured on opposite sides of the rafters, and tension means connecting the rigid right-angular members with said straps.
