JASPER BLACKBURN, F WEBSTER GBOVES, MISSOUR.
naam ANCHOR.
Appncanun mea :une 2s, 1924. serial No. 721,929.
To all 'whom t may concern: l
i Be it known that I, JASPER BLACKBURN, a
citizen of the United States, and resident of the city of Webster Groves, county of St. I Louis, and State of Missouri, have invented certain new and useful Improvements in EarthAnchors, of'which the following is a specification, containing a full, clear, and
'exact description, reference being had to the accompanying drawings, forming a part thereof.
.My invention relates to improvements in 'earth .anchorsand has for its primary object a construction ofanchor which may be anchored into the earth at spaced apart positions and the upper portion of the anchor compressing the earth on the remaining or lower portion of the anchor.
In the drawings:
Fig. 1 is a side elevation of my improved anchorcontracted and in a position to be set into the anchor hole formed in the earth;
Fig. 2 is a top plan View with the anchor rod in section;
Fig. 3 is a side elevation of the anchor Vset in the hole and anchored therein when in use;
Fig.4 is a top plan View of the lower p0rtion or expansible part of the anchor, the
0 upper portion being removed, and the rods which expand vthe anchor blades, and the anchor rod being in section;
Fig. 5 is a section taken on 'the line of Fig. 4 and looking in the direction of 35 the arrow illustrating the means by which the anchorblade expanding rodsare secured to the blades;` and Fig. 6 is a sectional elevation taken on mgthe line 6 6 of Fig. 1 looking in the direc- "tion of the arrows. e l Referring to the drawings-7 indicates the bottom or crown plate and is provided at diametrically opposite portions with guide anges 8 and 9. The purpose of these is to guide and hold in position the anchor blades 10 and 11, which are adapted to slide in their in and out movements between these guide flanges. Formed integral with the bottom or crown plate 7 and projecting 5 from Vtheupper surface thereof is an angular stud 1.2, this angular stud 12 is provided near its base and on opposite sides thereof with slots 13, and on its uppir end with a flange 14 on opposite sides thereof.
Formed through the bottoml o1' crown plate and the angular stud l2 is an opening '15 in which the anchor rod 16 is domed,
and located on the lower end of the anchor .rod 16 is a nut 17 for securing the anchor rod 16 to theanchor.` The anchor blades 10 and 11 are provided with slotsI 18 in which the angular stud 12 is mounted and these blades 10 and 11 slidein the slots 13 formed in the angular stud 12. It will be noted in this connection that the angulaistud 12 also answers as a guide for. the movements of the anchor blades 10 and v11..
19 and 20 form,l another pair of anchor blades which are mounted on the iirst mentioned bladeslO and 11. but
or superimposed are arranged to expand together and be collapsed or drawn in a direction at right angles to lthe movement of the blades 10 and l1. The blades 19 and 20 are likewise provided with slots 21 and 22 in which the angular stud 12 is located. These blades 19 and 2O are located beneath the :[ianges 14 face with an integralV pocket 23. This pocket is open at its top and inner end, or in reality is merely composed of two side walls e, and an end wall uniting the same. The inner surfaces ofthe side walls of each pocket are provided with grooves 211:, and connecting the grooves is a slight .Flange 25, and a shoulder 26 arran ed in front of the grooves. The pockets 1n each plate are formed precisely alike and as previously described. These pockets are arranged to receive rods or links 27 for expanding the anchor blades. .It will be observed from Figs. 5 and 6 that each end of these rods is provided with opposite ribs or shoulders 2S and on the inside of the shoulders with re- -cesses 29. In order to connect the endsI of the rods in the pockets 23 the'shoulders 28 formed on -the rods areinserted in the recesses or grooves 24. It will be understood to permit this insertion the rods must be held almost horizontally. After this :is done, if desired, the corners 30 may be bent in the recesses 29 formed in the rods adjaof the rods 27 are pivotally united to the outer ends of the anchor- blades 10, 11, 19 and 20. The upper end ofthe rods 27 are formed similar to the lower ends and are' connected to a frusto conical member 31, this member is of skeleton formation, and
is provided with cut away portions 32 so.
that when this member is collapsed the rods 27 may pass therein (see'Figs 1, 2 and 3).
These cut away portions also permit the -upper ends of the rods to be connected in p the ockets formed in the conical member, as illustrated in Fig. 6. It may be noted in this connectionthat the upper ends are first connected in the sockets in the conical mem ber and then the lower ends are connected in the sockets in the anchor blades.
The frusto conical member 31 is formed on its underneath surface with a series of sockets 33 which are constructed like the sockets formed in the ends of the anchor plates and in which the up r ends of the rods 27 are located. It will e noted in this connection that the sockets in the anchor plates and the sockets in the conical member 31 `are formed the same, likewise both ends of the rods 27 are constructed alike, and the upper ends of the 'rods 27 are seated in the sockets formed in the member 31 in the manner described with relation to connecting the lower ends of the rods 27 in the sockets 23 formed on the anchor plates.
The conical member 31 has an opening 34 through which the anchor rod 16 passes, the member 31 is adapted to be moved downwardly on this anchor rod in the expansion of the blades 10, 11, 19 and 20. In other words by forcin this conical member 31 downwardly the ladesare expanded, as illustrated in Figs. 3 and 4, and when it is moved up, as in Fig. 1, the blades are contracted,
When the anchor has been made-as previously described, it is adjusted in the form,
shown in Figs. 1 and 2 and then set in the hole 35 (Fig. 3). After it has been seated in the hole, the anchor blades 10, 11, .19'
and 20 are expanded by. hammering on-the conical member 31 and: these bladesV are forced out into the earth, and when the blades have been expanded,.it will be noted from Fi 3 that the `conical member will be seate on the uppermost anchor blades. When it has been expanded in this form, a'body of rock 36 is thrown into the hole on to of the conical member 31 and tamped, thls tamp'ing will wedge the conical member in the hole. It will also pack the earth above the anchor blades. It will be n'oted'iny this connection that my anchor is anchored in the earth by means of the blades and by means of the conical member 31 and body of rock. It will further be noted that the u per surface of the member 31 is honey-comhed or roughened, so as to vcatch'the rock and not let it pass through or slip off of the surface.
It will be observed that the conical member 31 performs two functions, by driving down on 1t, it expands the blades, and when seated and crushed rocks tamped thereon on top of it, it answers as an` auxiliary anchoringV means.
Having fully described my invention, what I claim is l. An anchor comprising a base plate, an anchor rod secured thereto, a pair of expanding blades mounted on said base plate,
. a conicalmember adapted to slide over the anchor rod, a pivotal connection between the expanding blades and cone whereby when the cone is pressed down, the blades are expanded, said coneada ted `to be wedged into a hole in a position a ove the expanding plates.
2. An anchor comprising a base, a plurality of expanding blades mounted on the base, an anchor rod secured to the base,- a conical member slidabl mounted on the anchor rod and pivotal yconnectedto the expandin blades for expanding the same, when sai cone is moved downward, 3. An anchor comprising a base, expanding blades slidably mounted on the base, an anchor rod secured -to the base, a conical surface mounted on the lanchor rod and links pivotally connected t said ,cone and expanding blades for expanding the same, when said cone is moved toward the base, said cone adapted to `be wedged into a hole by means of a body of crushed rock or like material, and the earth above the expanding blades be simultaneously packed thereby.
4. An anchor comprisinga base, a plu rality of expanding blades mounted on the base, an anchor .rod'secured to the base, a conical member provided with a roughened upper surface and cutaway ortions slidably mounted on the anchor ro and pivotally connected to the ex anding blades for expanding the same, w en said cone is forced toward said base;
5. An anchor comprisinga base, expanding blades mounted on the base, an anchor rod-secured to the base, a'coni'cal member mounted on the anchor rod, and connections between the conical member and the expand- .ing blades whereby saidblades are expanded have signed my name to this specification. Y
