BOLT-ANCHOR.
Patented Septp'i, 1920.
Application filed August 20, 1917. Serial No.- 187,065.
To aZZ whom it may concern:
Be it known that I, JosEPH KENNEDY, a citizen of the United States of America, and a resident of Richmond Hill, county of (Queens, and State of New York, have invented certain new and useful Improvements in Bolt-Anchors, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
This invention relates to an improved bolt anchor for securing a threaded element as a belt or other fastening device in an aperture in a wall or other building construction of brick, stone, cementitious material and the like.
My improved anchor in its broadest as-f pects is designed to utilize the combined advantages and beneficial effects of one or more plugs or socket members of relatively hard or resistant material, at least one of which is adapted to receive and hold a bolt or other fastening device; and one or more deformable sleeves of relatively soft ma terial swaged or crowded into the space be tween the plug or plugs and the walls of the anchorage aperture, whereby the plug or plugs are gripped and firmly held in the wall or building construction.
A, great advantage of a sleeve or sleeves of soft metal, lies in the fact of the tenacious hold of the metal upon the roughened surface of the wall and upon the exterior of the wall plug, and also in the fact that the soft metal readily accommodates itself to all the irregularities of shape.
In my device, those plugs of relatively hard or resistant material which do not actually receive and hold the bolt, act to form guides or centering devices for the bolt. and the deformable sleeve or sleeves of relatively soft material are preferably sepa rate and independent from the plugs and are swa-ge'd or crowded into contact with each other and displaced laterally, in the space between the plug or plugs and the walls of the anchorage aperture by endwise pressure between the plugs. The swaging and crowding of the soft metal may be aided with a suitable tool, if desired, although in the present form of the invention, this would not be necessary.
My device is extremely practical and cheap to manufacture.
In order that my invention may be thoroughly understood I will now proceed to describe the same in the following specification, and then point outv the novel features thereof in appended claims.
- Referring to the drawings:
Figure 1. is a longitudinal sectional elevation of a device embodying my invention with the parts thereof shown in place with in an aperture in a wall and shown in the relative positions and in the condition be fore expansion.
big. 2 1s a similar view of the same parts after expansion.
Fig. 3 is a longitudinal sectional elevation of a slightly modified'form of construction with theparts shown in the positions and condition they assume after expansion with .a bolt in place holding an object against the wall. Like characters of corresponding parts in all-the figures.
reference designate Aidesignates a portion of a wall or other i building construction, of brick, for instance,
and B the hole for the anchor. t is an interiorly threaded. plug of hard metal provided with a base flange it against which is seated a deformable sleeve o of relatively soft metal, such, for example, as lead or an alloy of lead. Another deformable sleeve it; bears against the sleeve '0 and the meeting edges :23 of these sleeves are meter-ably beveled. Another guiding and centering plug y is inserted in the outer end of the sleeve w. This has an enlarged portion adapted to fit the hole 13 and forming a shoulder e which abuts against the end of the sleeve 10. The sleeves '0 and w are swaged and crowded into the anchorage aperture by driving in the outer plug 3 or by drawing the plugs t and g toward each other by the insertion of a bolt.
The construction shown in Fig. 2 is substantially like that shown in Fig. 1 except that a single deformable sleeve C is shown instead-of a plurality of sleeves as indicated in Fig. 1. In Fig. 2 the sleeve C is shown swaged and crowded into the anchorage aperture and filling the irregularities of the walls ofthe aperture.
Fig. 3 shows a' construction similar to that shown in Fig. 2 but the parts of' the plug 25 and y which fit within the sleeve C are longer than those of the former case so that they nearly or quite meet after eXpansion;.; This figure also shows a bolt 0 in place holding an object P against the/wall.
This application is a continuationin' part of application for a patent filed by. me on the 13th of August, 1914, and given Serial No. 856,612. I I
l/Vhat I claim is:
1. Means for anchoring a bolt or other fastening device in an aperture in a wall or other building construction, comprising a plug of hard metal having a flange and a smaller non-tapering portion, said flange forming an outwardly facing shoulder, a similar plug having a flange and a smaller non-tapering portion, said flange forming an inwardly facing shoulder, and a sepa rate independent deformable hollow sleeve of relatively soft material arranged between said shoulders and fitting over the smaller non-tapering portions of the plugs, and means for moving said plugs toward'each other to thereby cause outward expansion of the sleeve by longitudinal pressure of said shoulders thereon.
fastening device in an aperturein a Wall or other building construction, comprising an internally' threaded plug of hard metal having a flange and a smaller non-tapering portion, said forming an 'outwardlyfacing shoulder, asimilar plug provided with a 2. cans for anchoringa bolt or other between said shoulders and fitting over the smaller non-tapering portions of the plugs,
and a bolt adap'tedto'p s through the'c'l'earance hole in one of"saidplugs"and'toj'engage the threads of the other plug arranged to flan e formin anoutwardl facin shoulf! D b der, a similar plug provided with a central clearan'cehole "having a flange :and a smaller portion,'said' flange forming an inwardly facing shoulder, and a, pair of independent deformable hollow-sleeves of relatively soft material arranged between said shoulders and fitting over the smaller portions of the plugs,'the outer ends of said sleeves fitting against said shoulders and with their inner ends projecting beyond the smaller portions of the plugs, beveledinwardly and abutting against each otheryand 'a bolt adapted to pass through" the clear- .ance hole in one of said plugs and to engage the threads of the other plug.
In witness whereof, I have my hand this lltli day of August, {1917,
