Application April 24, 1957, Serial No. 654,853

2 Claims. (CI. 81-53) The present invention relates to a special purpose hand tool or implement which is expressly designed and suitably constructed to enable a user thereof to turn and unscrew an upstanding anchor rod from its embedded base and, having done so, to exert a pull thereon sufiicient to withdraw the rod from the ground and to thereafter detach it from the tool.

Briefly, the invention in its preferred embodiment is characterized by a one-piece T-shaped member having hollow tubular portions. One portion hereinafter referred to as the shank has a crosshead connected to its upper end and serving as a turning handle. At the lower end there is an enlarged socket member for reception of the eye at the upper end of the anchor rod which is to be pulled. The socket member has diametrically or equivalently arranged slots to accommodate a bolt. The bolt affords an operating connection between the socket member and eye.

An object of the invention is to structurally, functionally and otherwise improve upon similarly constructed and performing tools and implements and, having done so, to provide a construction in which manufacturers will find their manufacturing requirements and economies satisfactorily met and users will finde a reliably constructed adaptation which will fulfill their needs and enable them to accomplish a job which heretofore could not have been aptly done with available tools.

Another object of the invention is to utilize the open end portions of the handle of the T-member as socket means for attachment and retention of a crank-like handgrip which latter is held mova'bly in place by a simple retaining clip.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views:

Fig. 1 is a perspective view of an exploded type showing the complete anchor rod puller with the parts, of course, separated;

Fig. 2 is an enlarged sectional view with portions appearing in elevation and showing the puller assembled and in use;

Figs. 3, 4 and are detail sections of a fragmentary nature taken on the line 3-3, 44, and 5--5, respectively, of Fig. 2.

With reference briefly to the views of the drawing, the hollow tubular T-shaped member is denoted by the numeral 6, the attachable and detachable crank-like handgrip at 8, the bolt means at 10, and the anchor rod at 12.

The T-shaped member is made up of several pieces of pipe or pipe-sections and one of these is herein denoted as the stem or shank 14 and at the upper end it is connected to the intermediate portion of a crosshead 16 which constitutes convenient handle means. At its lower end it is equipped with a collar 18 joined to the upper end of a larger section 20 constituting a socket member and which is adapted as seen in Fig. 2 to receive the eye 22 of the anchor rod 12 therein for bolted retention. The bolt means 10 comprises a bolt having a head 24 and a screw-threaded shank 26 with the shank extending through elongated diametrically opposite slots 28 formed in the socket member. A retaining nut 30 and

washers

32 and 34 serve to properly join the bolt with the slotted socket member.

The crank-like hand-grip comprises a short tube 36 which is fitted telescopically into the end portion of the handle 16 as shown and is provided with keeper holes 38 registering with associated holes 40 to receive the inturned end portions or keepers 42 on the U-shaped assembling and retaining clip 44. A headed pin 46 is bolted at 48 to the member 36 and is enclosed in a sleeve 50 providing the upstanding hand-grip. In fact this hand-grip is swivelled on the pin and assists in enabling one to more satisfactorily use the tool.

It is repeated that the invention has to do with a simple, economical and practical anchor rod puller which functions, obviously, to enable the user to unscrew and pull an anchor rod from an embedded anchor base or plate. The socket fits over the eye of the anchor rod which is to be pulled in the manner seen in Fig. 2. With the slots opposite the eye the bolt 10 is passed through the slots and is secured in place by the Washer and nut means depicted in Fig. 2. Thus the rod and socket member are operably connected to each other making it possible for the user to not only unscrew but to yank the rod out of the ground. The bolt serves not only in the unscrewing step but also as the means for coupling the eye of the rod to the socket member. The tool affords the user a reliable grip and makes it unnecessary for him to Worry about it slipping off or out of place or having to needlessly stoop and wrestle, as it were, with the job as is the situation in attempting to employ make-shift devices.

The present invention is not to be mistakenly compared to a so-called socket-type wrench as might be employed in applying and removing nuts, bolts or for turning keys and valves and so on. Instead, it is a special purpose tool which is aptly treated as an anchor rod puller. It lends itself properly to the purposes for which it is intended and is highly efiicient.

The foregoing is considered as illustrative only of the principles of the invention. Further, since: numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1 An anchor rod puller comprising a socket member for telescopic reception of the usual eye-equipped upper end of the anchor rod, said socket member having diametrically opposite elongated slots therein adapted to register with the eye on said rod, a bolt having end portions removably mounted in the slots and adapted to extend through the eye and to .thus mechanically and operably connect the eye with the socket member, and handle means carried by said socket member, comprising a T-shaped member, the companion portions of which are of hollow tubular form, one portion constituting a shank and being connected with the socket member, and the other portion a handle the end portions of which are adapted to receive a readily attachable and detachable crank-like hand-grip.

2. A tool which lends itself to the job of pulling and extracting an anchor rod and which assists in unscrewing the rod from its embedded anchoring 'base comprising a T-shaped member the companion portions of which are of hollow form, one portion constituting a shank and being provided at its lower end with a socket member for telescopic reception of the usual eye-equipped upperend,

of the anchor rod, said socket member having diametrically opposite slots, a bolt having end portions reinovably mounted in ,said slots, the otherportion of said bolt providing gripping means and'the respective end portions:

thereof being adaptedto function as selectively usable sockets, a detachable crank-like hand-grip comprising, a

short tube which is adaptedto be telescopically. fitted into cooperating end portion, aheaded pin carried by the outerend, of said short tube and provided with a swivelly mounted hand-grip. o
