PATE T or ice This invention relates to ans-anchoring device. An object of the invention is the provision of a device for anchoring rods in which a plurality of anchoring means are supported by pivotally mounted arms from a base member which is connected to the rod .to be anchored.

Another object of the invention is the provision of an anchoring devicewhich includes a base member and arms radiating therefrom and pivotally connected .to said base member, the upper freeiend of the arms adapted to pivotally support anchoring members which are elongated and dished, the inner free ends of the anchoring means being engageable with a tamping element for forcing the anchoring members supported by the arms from a substantially vertical position to a substantially horizontal position so that when concrete or other material is filled into the hole in which the anchoring device is located, the device will be held against movement.

A further object of the invention is the .provision of an anchoring device provided with a base member from which project arms removably connected with the base member, the upper free endsof thearms being removably connected'with elongated dish-shaped anchoring members which are movable outwardly and supported by th'earms from the .axis of the base member andadapted to.

be .forced through the walls of .a hole .or pit which the anchoring device is placed.

This invention will bebest understood from a consideration of the following detailed description, in view of the accompanying drawing form ing a part of the specification; nevertheless, it is to be understood-that the invention is not confined to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 5 is a vertical section taken along the line 5-5 of Figure 6,

Figure 6 is a vertical section taken along the line 66 of Figure 5, and

Figure 7 is a fragmentary view in perspective,

into

or supporting for the anchoring members.

Figure .8 is .a fragmentary vertical section showing a'pocketl H I v Referring'more particularly to the drawing, .10 indicates a .circular base member having .a centralpassage 11 into which is threaded, as shown at l2, the lower end of a 13 which is adaptedto ,be anchored in position. Nuts 14 and Y15 rigidlysecure the rod to the base member.

Arms 1 6 project radially from the base member 10 and .any number of the arms maybe employed which will vbe suitable for the particu- .lar work.- :Ihese .arms are provided with reinforcing ribs 1.7 located at right :angles to a pair of the :opposite faces =of thearms. These ribs areformed integrally with the arms. The lower end .of each :arm .lfltis substantially circular as shown atilli. Upon the opposite faces of the arm and adjacent the circular portion 18 are lugs .1 9.' These lugs have their opposite ends rounded, .as shown at .20, with the side edges flattened as shown at 21. r .The inner .end 25 ;.of .each of a plurality of pockets-which are formed in the base .member 10 is rounded to conform to the roundedportion 18 of the arm 16. A side wall 26 of the pocket is inclined upon which the outer edge of the arm 16 rests when the arms are in extended position. The mouth of the pocket is sufficiently wide that the lower ends of the arms 16 may be inserted within the pockets. The portion of the'Ipoc-ket just described is the central portion in which the rounded portion 18 of the arm is located.

.At each .side of the central portion a lip .27 L

is provided which is adapted to engage the upper rounded portion 20 of the lugs 19 to prevent the lower ends of the arms from escaping from the pocket when said arms are in a substantially vertical position as shown in Fig. 3. Upon each side of the central portion of the pocket and adjacent the periphery of the base member 10 are provided flanges 30 which engage the portions 31 of the lower end of the arm 16 and the rounded portions 20 of the lugs 19 for aiding in maintaining the arms in the pocket in connection with the lips 2'7. The space 27 between the end of each lip 27 and the free edge of the flange 30 is sufficient to permit the lugs 19 to pass into the pockets when the arms are inclined outwardly from the rod 13, the lips 27 and the flanges 30 being in co-operative engagement with the lug 19 to prevent the base member 10 from dropping off the arms when the rod 13 is lowered into the pit formed in the ground.

The upper ends of the arms 16 are constructed in a manner similar to the construction at the lower ends and the pockets formed in elongated dished anchoring members 36 are somewhat similar to the pockets formed in the base member 10.

Referring more particularly to Figs. 3, 5, and 6, it will be seen that the upper extreme ends of the arms 16 are rounded, as shown at 37, and this rounded portion rides upon the circular portion 38 of the pocket 39 formed in a boss 40 at the underface of each elongated member 36. A pair of flanges 41 and 42 project inwardly from the walls of the central portion and these flanges which are located upon opposite sides of the rounded portion 37 of the arms 16 lie in fiat contact with the flat faces of the upper end of the arm.

Lugs 45 are formed integrally on the opposite flat faces of the upper end of the arm 16 and these lugs are adapted to ride in the

curved portions

46 and 47 of the respective flanges 41 and 42. The opposite ends of the lugs are rounded as shown at 48, and are adapted to ride on the curved portions just mentioned. The upper ends of the lugs are adapted to be located between the

straight edges

50 and 51 of the flanges 41 and 42 when the elongated members 36 are in an operative position, as shown in Fig. 4.

A shoulder 52 is formed in the boss 40 and is adapted to engage an edge of the arm 16 when the member 36 is in inoperative position as shown in Fig. 3. By this construction the members 36 are pivotally connected with the arm 16 but may be readily removed from the arms when desired.

A tamping member 55 has a radial slot 56 which is adapted to receive the rod 13. The tamping member is provided with an eye 57 to which a chain is secured for removing the tamping memher after the anchoring device is in position. The inner face of the'tamping member has a comically-shaped portion 58 for guiding the inner rounded ends 59 of the members 56 toward an annular groove 60 formed beneath a flange 61 of the tamping member 55.

Each of the members 36 are elongated and are dished so that the outer faces of said members will present a hollow portion to the ground when it is forcedthrough the walls of the well 35, as shown in Fig. 4. The outer extreme ends of the members 36 are pointed, as shown at 62, so that said members may be forced through the side walls of the pit. V

The operation of inserting the device in the pit 35 in anchoring position is as follows: The arms 16, as shown in Fig. 3, are moved to a substantially vertical position so that the anchoring members 36 will incline at a slight angle to the vertical with the rounded inner ends 59 of said members being engaged within the annular groove 60 of the tamping head 55.

A spring member 65 is held in place by the nut 14 on the base member 10 and is adapted to engage the arm 16 tending to force the arms outwardly. The anchoring device is let down into the pit and the tamping head 55 is forced downwardly whereby the members 36 will be forced outwardly through the side wall of the pit 35 and these members are guided in their outward movements by the knee action of the arms 16.

When the tamping element 55 has moved the arms to the proper position the chain connected to the eye 5'7 is elevated, thereby raising the tamping member. Due to the slot 56, the tamping member may be readily slid ofi of the rod 13. The pit is then filled with concrete or any suitable material for securing the anchoring device in the pit.

I claim:

1. An anchoring device comprising a base member, a rod secured axially of the base member, radiating arms pivotally and removably connected to the base member, an elongated dished member for each arm, means for pivotally and removably connecting theouter ends of the arms to intermediate portions of the dished members, the inner ends of the dished members being reduced and rounded, and a removable tamping member having an annular groove at the inner face thereof to receive the rounded ends of the dished members.

2. An anchoring device comprising a base member, a rod secured axially of the base member, radiating arms pivotally and removably connected to the base member, an elongated dished member for each arm, means for pivotally and removably connecting the outer ends of the arms to intermediate portions of the dished members, the inner ends of the dished members being reduced and rounded, a spring member secured to the base member and provided with fingers tending to force the arms radially outwardly, a tamping head having a groove to loosely receive the inner ends of the dished members, said head having a central opening and a radial slot extending from the opening to provide for the removal and the application of the tamping head to the rod and dished members.
