J. H. PHILLIPS ANCHORING DEVICE Filed ma 29. 1925 WMQ f/wl 7M M Patented Apr. 1, 1939 UNETED STATS JOHN H. PHILLIPS, OF CHICAGO, ILLINOIS ANCI-IOBING DEVICE Application filed May 29,
My invention relates to anchoring devices and particularly to eXpansible anchor bolts. The invention has among its other objects the production of a device of the kind described,
5 which is simple, convenient, reliable, inexpensive and satisfactory for use wherever found applicable. A particular object of the invention is to provide an improved selfdrilling device of the kind described which 10 can be manufactured at a relatively low cost.
Another particular object of the invention is to provide an improved device of the kind described which can be used in connection with standard pipe fittings and the like.
In accordance with the features of the invention, tubular expansible anchor bolts are formed from pipes, tubes or the like and each is provided with drill teeth at one end and pipe threads at the other end. Preferably, each bolt is threaded for a greater distance than is the conventional practice. The threaded ends of said lengths are then tapered so that the lengths may be seated. 1n
,, chucks or the like to permit them to be used as drills. In the preferred embodiment of the invention the lengths are provided with slots intermediate their ends to form Weakened portions adjacent the drill teeth so that the devices may be easily expanded to secure them in walls and the like. After the bolts have been secured in a wall, standard pipe fittings or the equivalent may be secured thereto to secure other articles or apparatus 0 to the bolts.
" Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.
To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.
In the drawings, wherein like reference characters indicate like or corresponding parts: 7
Figure 1 is a longitudinal section through. an anchoring device embodying my invention, the anchoring device being shown in 1925. Serial No. 33,724.
connection with a chuck ed to be seated; v
Figure 2 shows my improved anchoring device firmly fixed in a ceiling or the like and provided with a coupling member whereby it supports a load; I
Figure 3 is an enlarged longitudial section taken substantially on the same line as Figure 1 but showing in more detail certain features of construction; and i 60 Fig. 4c is a section taken on line 44 of Fig. 1.
Referring to the drawings, wherein I have shown a preferred form of the invention, the reference character 15 designates a tubular shell which is formed of any suitable material such as pipe, tubes, or a plate. In some instances, the tubular shell may be cast, and in other'instance's may comprise complementary sections embodying the features of the invention. The tubular shell 15 is provided at one end with a plurality of cutting teeth 16 and 17, or the equivalent. At its other end it is preferably pipe threaded. as at 18. The pipe 7 threads 18 preferably extend a greater distance along the tubular shell 15 than is the conventional practice in the threading of pipes and the like, but in some instances'I may form a shorter thread upon the shell. The threaded end of the shell is shown ta-' 30 pered, as at 20, so that the shell may be seated in a tapered aperture 21 formed in a chuck in which it is adapt- 22. As best illustrated in Figure 3, the shell is so tapered at its threaded end thatthe shell may be inserted in the tapered aperture 21 without injuring the pipe threads 18. Thus the smallest diameter of the tapered portion is substantially equal to the smallest diameter at the base of the pipe threads. The chuck 22 may be formed with a. plurality of intersect ing bores 24; and 25. This permits material cut by the drill teeth 16 and 17 to pass through the shell 15 and out through the bores 24 and 25, and also permits the shell to be unseated from the chuck by theinsertionof a key into one of the bores 24 and 25. Intermediate-its ends the shell 15 is preferably provided with a plurality of slots 2?, or theequivalent which form weakened portions 28 adjacent ioo the teeth 16 and 17. The purpose of this construction will presently appear.
The shell 15 may be driven into a ceiling 30 or the like or into a Wall formed of concrete, etc., the shell 15 being in the nature of a stone drill. To drive the shell 15 into the ceiling 30, the shell is seated in the chuck 22 and the chuck is attached to any suitable hammer device, whereby reciprocatory motion may be imparted to the shell, the shell being simultaneously rotated or oscillated. lVhen driven into the ceiling, the shell 15 forms a substantially cylindrical hole 31 therein. After the shell 15 has been driven the desired distance into the ceiling 30 it is removed therefrom and a tapered plug 32 is seated in the drill end thereof. The shell is again driven into the hole 31 and as it approaches the bottom of the hole will be e:-; panded by the plug 32 in the manner illustrated in Figure 2, the hole 31 being enlarged at its bottom as indicated at 34:. The shell 15 is then firmly fixed in the ceiling 30 and the chuck 22 may be removed therefrom.
A standard pipe fitting or any suitable coupling member 35 may be threaded upon the threaded upon the lower end of the pipe section 36. The bracket member 37 may be of any suitable size and form but in this instance comprises an annulus 38 adapted to receive a nice 40 which mav be a as or water line or L u b A. 7
other apparatus.
I do not limit myself to the use of the same shell 15 for drilling the hole 31 as for drilling the enlargement 3% at the bottom of the hole, as a plurality of substantially cylindrical holes 31 could be drilled with a drill shell 15 and shells of cheaper manufacture could be employed in the final drilling or reaming operation. Thus, if the drill shell 15 were made of a suitably hard material, it could be employed for drilling a plurality of the holes 31. The anchoring devices finally secured in the holes 31 could be of cheaper form, although after the teeth of the drill shell 13 became Worn, it could be used as an anchor i-ng apparatus therefrom, a portion of said threaded portion being tapered for frictional-' ly engaging a chuck having a correspondingsigned my name.
