METAL FIRE BLOCK.
Specification of Letters Patent. Patented Apr. llll, 11.922
' Application filed September 13, 1920, Serial No. 409,990."
and useful Improvements in Metal Fire Blocks, of which the following is a specification.
This invention relates'to fire blocks and is preferably constructed of sheet metal, the object being to provide a closure forthe space between the studding and weather boarding and plastering of a building to prevent the space between these parts acting as a flue or draft opening in case of fire. The prime feature of the inventio nis in so constructing the fire block that it may be adjusted longitudinally to completely close spaces of varying lengths, it frequently occurring that the studdings are placed at different distances apart.
A further feature of the invention is in providing means for interlocking the adj listable sections together, so that the sections will always remain in a horizontal position, although they may be adjusted lengthwise.
A further feature of the invention is the provision of means for anchoring the fire blocks to the faces of the studding, so that the fire blocks can be quickly and easily applied to use.
Other objects and advantages will be hereinafter more fully set forth and pointed out in the accompanying specification.
In the accompanylng drawings which are made a part of this application,
Figure 1 is a perspective view showing one of the fire blocks applied to use,
Figure 2 is a top plan View of the fire block, Figure 3 is a transverse sectional view as seen on line 3-3, Figure 2,
Figure 4 is an end elevation of the fire block, and
Figure '5 is atop plan view of a slightly modified form of fire block.
Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates studding which is of the usual form used in constructing frame buildings, 2 indicates weather boarding, such as is placed on the outside of the studding, and 3 indicates the plastering, such as isplaced on the inner face of the studding.
It has been the custom heretofore to form fire blocks of wood, such as parts of studding, or the like, and nail the same between the studding to close the space between the plastering and weather boarding and prevent a draft therethrough; but, in the presentinstance the fire block 4 is constructed preferably of sheet'metal and formed in two sections 5 and 6, the section 5 having a channel 7 extended longitudinally thereof for the reception of a rib 8, which is formed upon and extends longitudinally of the section 6, the channel and rib being so shaped in cross section that they will interlock with each other and hold the two sections of the fire block in proper alignment, and as the channel 7 telescopically receives the rib 8 the sections 5 and 6 of the fire block may be adjusted longitudinally to adapt the same for the varying distances between the studding members. The ends 9 and 10 of the sections 5 and 6 are bent upwardly at substantially right angles to the fire block proper and fit against the adjacent faces of the studding, any suitable means being provided for securing said ends to the studding, but preferably by forming brads 11 and 12, which brads are preferably so cut from the end sections that they will each present a pointed edge to the studding and may be readily driven into the studding when a blow is delivered against the inner face of the end members. The brads 11 and 12 are formed by making an angular incision in the end members and bending outwardly the severed portions, thereby leaving the brads integral with the end sections at one edge, consequently, when they are driven into the studding they will securely support the fire block in position. The brads 11 and 12 also serve to hold the blocks 4 against any lateral swinging movement.
The channel 7 and rib 8 not only provide means for holding the sections 5 and 6 together,but as they are formed integrally with these sections by bending up parts of the sections, they form a very rigid structure and lOQ extend the full length of the sections, so that the ends 9 and 10 will be reinforced,
In Figure 5 is shown a modified form of structure in which the "channel and rib are dispensed with and the edges of one of the manufactured and can be quickly applied to use as it does not require any sawing to fit the same, and but very little effort required to anchor the ends of the fire block to the studding, and as these fire blocks are made in sec tions they can be extended or contracted to fit between the studding of varying distances apart, and if the space is so small between the studding that the sections when moved to their -shortest length are still too long, the ends of the sections may be clipped off so as to shorten the structure.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
1. A fire block comprising a pair of sections having angularly disposed ends, interlocking reinforcing means on said sections formed by striking up portions of said sections along their longitudinal centers, and means integral with said ends for anchoring the end members in operative position.
2. Means for closing the spa'cebetween the studding of a building comprising a twopart metallic fire block, a longitudinally extending channel on one section and a co-operamarae ating rib on the other section, said channel and rib being formed b striking up portions of said sections said 0 annel and rib being substantially triangular shaped in cross sections and interlocking with each other and means for anchorin the outer ends of the sections to the stud mg.
3. A fire block for building structures comprising a pair of telescoping sections having their outer. ends extended at an angle, a longitudinally extending channel on one of said members, a co-operating rib on the other member adapted to enter said-channel and telescopically connect the two members, and brads struck from the end portions for anchorin the outer ends of the sections to parts of t e building structure.
In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 10th da of September, A. D. nineteen hundred an twenty.
