specmwmof'uwent. Patented sept. 29, 1914.r
Application tiled August 14, 1913. Serial No. 784,6?5.
l To all whom it may concern:
Be it known that I, JOSEPH KENNEDY, a citizen of the United States, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Expansion Bolt-Anchors, of which the following is a specification, reference beinghad to the accompanying drawings, forming a. part thereof.
My invention relates to .bolt anchors such as can he expanded within a hole drilled in a wall, floor or other structure and thus secui-ely allixed to the structure. lts object is to provide an extremely effective device of this character which has advantages over those heretofore known.
I will describe my invention in the following specification, and then point out the novel features thereof in appended claims.
y Referring to the drawings, Figure l is a sectional elevation of a well with an expansion bolt anchor 'therein' which is made in accordance with this invention. In Fig. 2
the anchor itself is shown in longitudinal` elevation with its outer member shown in section. A. transverse section of the device illustrated in Fig. 2v is shown in Fig. 3, the section in this figure being taken on the line 3-3 of Fig. 2.
Like characters of reference designate corresponding parts in all'the figures.
According to this invention, the bolt anchor tomprises an inner member 10 of hard metal, and an outer member 11 of soft metal. ln va desirable form which is illustrated in Figs. l, 2 and 11, the inner member is internally threaded as at l2 to receive the threads 'of a bolt and its outer surface is constructed 'in the form of a series of truncated cones 13 which taper toward the outer end of the device. These cones may be and preferably are of transverse dimensions progressively increasing toward the inner end of theA device with their major bases overlapping the minor bases of the adjacent cones.
The outer member 1l which may be of lead for example, fits over the notched surface of the inner member and extends bcyond the front end thereof. Through this part which extends in front of the inner member is a clearance hole ll for the bolt which is to be used with the device. The
outer surface of the outer member is shown as cylindrical although l do not 'intend to limit myself t'o-this particular form.
Referring now to Fig. 11 I Will describe the manner in which this device is used. A hole 20 is drilled in a structure 21 of about the diameter of the outer member l1 `and of a depth somewhat greater than the length of the ,anchor device. The latter is then inserted in this hole and a bolt passed through a Washer 23, which overlaps the outer end of the hole 20, and screwed into/ the threads l2 of the inner member. As soon as the head of the bolt en ages the washer, the inner member will be rawn toward the outside of the hole forcing itself through the soft outer member and on account of Athe wedge-like form of its outer surface, forcing the material ofl the outer member against the surface of the hole. The anchorage member thus becomes s ecurely affixed to. the structure 21. If dee sired the bolt may be removed and inserted again at will as the threaded bore of the internal member forms durable screw threads for the reception of the threads of the bolt.
Various modifications o f this invention may be made within the spirit and scope of the claims.
lVhat l claim is: 1,'An expansion bolt anchor comprising an inner member of hard metal having a longitudinal' bore., the outside of said mem ber being in the form ofv a series of truncated cones. and a relatively movable outer member of soft metal fitting over the inner,
member and extending beyond the smaller part olf said outer member being provided with a clearance hole in alinement with the threaded hole in the inner member.
3. An expan menos sion bolt anchor comprising In testimony whereof I have hereunto set'.
m hand n the presence of t wo subscribing wltnesses, this 11th dey of August, 1913.
