To collie-ham it 17mg concern.-
Be it known that I, ISAAC CHURCH, citizen of the United States, residing at Toledo,
in the county of Lucas and State of Ohio, have inventedcertaih new and useful'lmprovements in Expansion-Bolts; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art. to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
My invention relates to expansion-bolts of the character employed in attaching iron or wood to stone or brick work.
The object of theinvention is to provide an outer shell'that can be expandedwithin a hole or opening formed in the stone or wall, by means of a tapered threaded nut, when a bolt is screwed therein to secure a timber or like article in place.
The invention consists in the parts and coinbinations of parts hereinafter described, and pointed out in the claims.
In the drawings, Figure 1 is a side View of my expansion-bolt in position within a perforation, apart of the clamping-shell being broken away to disclose the position of the nut. Fig. 2 is a like view showing the clamping-shell upon the side at which the two sections meet in parallel relation. Fig. 3 is a longitudinal vertical section throligh the bolt, nut, and shell. Figs. 4, 5, and 6 are transverse views on lines a: as, y y, and 2e, respect ively, of Fig. 2.
A designates an expansion-shell, preferably 1 formed of malleable cast-iron, although it. my be forged from wrought-iron or steel, or
formed of brass, if desired. Shell Ais formed with two semi-cylindrical end portions or sections l3, conn ccied together by a flexible central. portion 0, the shell being opened when first constructed, with the end portions B we tending from the central portion in opposite directions. The central portion (3 is then bent to cause the two end portions to lie one upon the other, thereby forming a cylindrical shell, as shown. Each haif-section of the shell. is formed with a semicircular incline D, extending from the flexible portion 0 toward the end of the section, the incline terminatcan'be constructed with little expense.
ing at E in a diameter corresponding to the diameter of the bolt to be inserted; From the termination of the incline at E there are preferably semicircular recesses F, extending to nearthe end,wliere there is formed a semicircular opening G, corresponding to the diameter of the incline at E. By the construc- I tion described it will be seen that where the two sections are assembled there is an annular inclined portion and two circular hearings or guides for thebolt to be passed through.
ll designates a cone-shaped nut placed Within the inclined annular portion of the shell, with the inclination of the same in inverse order to that of the shell. The interior of the nut is screw-threaded for a portion of its length to receive a screw-threaded bolt I. Nut H is formed with two diametrically-op 7o posite lugs or guides J, which move in slots K, cut fromthe sides-ofthesectiens B, as shown in Figs. 2, 4, and 5. The end portionof the exterior of the shell is milled or corrugated at L, for the purpose of engaging with the *inte- 7 5 rior surface of the perforation or recesses M in the stone or wall.
From the above description the operation will be readily understood. To attach a hanger, whether of timber or iron, to a stone 8 or wall, recesswM is first formed; the shell is then contracted sufficiently to enter the same, nut I-l having been placed in position therein,
when the spring inherent in the central portion C will cause the milled end of the shell to bear against the sides of the recess to prevent the shell from turning therein. BoltIis-now passed. through a perforationin the hanger. and the free end screwed into nut H, when, upon the bolt being screwed sufficiently tight 90. against thehanger to draw the same against the stone or wall, the nut is drawn forward against the incline, thereby expanding the shell andholding the parts firmly in place.
' Bfrthe. construction described the (leglfie 5 e nut may he formed solid, thereby maintaining at all times. a circumferential-hold upon thethread, wherebythe'full power and strength are exercised without danger of i i-.169 juryto the thread of the bolt and allowing a removal of the bolt without disarranging the expansihle feature of the device.
What I claim is 1. In e11 expansion-bolt, ashell formed with an interior inclined annular portion and a cylindrical tapered nut within the same, in
combination with a threaded bolt within the nu t', as and for the purpose set forth.
2. In an expansion-bolt, a, cylindrical internally-inclined shell formed of tWo sections joined by a flexible portion intermediate the same, in combination with an inclined nut movable upon the incline of the shell, as
and for the purpose set forth.
3. In an expansion-bolt, a cylindrical shell formed. of a plurality of sections connected by a flexible central portion, each of the sections being formed with an inclined interior surface and a segment of an annulus, in combination with an oppositely tapered nut movable upon the incline of the sections, and
with projections to move Within the slots, as.
and for the purpose set forth.
I11 testimony that I claim the foregoing as my own I hereby afiix my signature in presence of two Witnesses.
