Description
Nov. 25,1947. c, E, CLAPPER ANCHOR STAKE Filed July 13, 1945 IN VEN TOR, @0562. [75/7/7612 BY Patented Nov. 25, 1947 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to improvements in anchor stakes and has for its general object a device of this kind which can be driven into the ground, anchored by means of adjustable fiukes, then when desired may be withdrawn by retracing the fiukes and withdrawing it from the ground.
One of the chief objects of the present invention is the provision of an anchor stake having means for forcing a series of flukes into the earth at substantially right angles to the axis of the post,- whereby there will be no tendency to raise the post upwardly as the flukes are set.
Another object of the invention is to produce a structure wherein the fiukes and the fluke operating means is securely anchored adjacent the point of the stake and manually operable from above the ground level.
Other objects are simplicity and sturdiness of construction, ease and efliciency of operation, and
adaptability for many and varied uses.
With these objects in view as well as others which will hereinafter appear during the course of the specification and claims reference will be had to the drawings wherein:
Figure 1 is a side elevation of an anchor stake partly broken away and embodying this invention.
Fig. 2 is a plan or top view of the stake.
Fig. 3 is an enlarged longitudinal sectional view of the lower end portion of the stake with the fiukes shown extended in dotted lines.
Fig. 4 is an enlarged cross sectional view taken on line IV-IV of Fig. 1.
Fig. 5 is a cross sectional view taken on line V-V of Fig. 3 with the fiukes shown extended in dotted lines.
Fig. 6 is an elevational view of the fluke mounting positioned in the sectioned stake casing,
Fig. 7 is a cross sectional view taken on line VII-VII of Fig. 3.
Throughout the several views like reference characters refer to similar parts and the numeral l0 designates a stake casing or tubing shown as circular in cross section and providing at its lower extremity with a substantially conical driving point l2 which is shouldered at l4 to receive the end of easing ill for firm abutment thereagainst. The shank iii of the point extends upwardly into the body of the housing and is securely fastened therein by means of screws IS. The upper portion of shank I6 is slotted at equally spaced intervals to form tongues 20 and grooves 22 having parallel side walls 24. The lower portion of each of these grooves are curved downwardly and outwardly at 26 to serve as a guide and bearing for the curved body of the fluke 28 as it is fluke 28 is extended and retracted. An annular ring 34 fits the inner wall of casing l0 and rests on top of the tongues 20 to each of which it is attached by means of screws 36 thus forming a chamber 38 for the fiukes and the fluke operating means. A rod 40 disposed axially in casing I0 is ofiset at 42 to present a shoulder 4'4 to rest against the bottom of chamber 38 with its reduced end portion rotatably mounted in a picket bearing 46 formed in the point l2. A sleeve 48 is rotatably fitted into ring 34 and is secured to rod 40 by pin 52. For positioning the pin 52 a hole 53 is provided in the wall of casing I0 through which the pin is inserted, after which a plug 55 is inserted to close hole 53. An annular ring 50 integral with sleeve 48 rests against the under side of ring 34 to prevent relative axial movement of the rod and supporting parts. That portion of rod 40 intermediate sleeve 48 and shoulder 44 is threaded at 54 to receive nut 56 which is secured against rotation by radial lugs 58 which rest in grooves 22 to permit movement of the nut axially of said casing.
The lower face of each of the lugs 53 is grooved at 60 to receive the arcuate head 52 of fluke 28. It will be noted that a depending lug 59 is provided at each side of the lug 58 to receive the narrowed head 62 of the fluke therebetween whereby a carrying pin 64 may be provided to pivot the fluke to the nut. The body 66 of the fluke is shown curved and when the nut is in the raised position as shown in solid lines in Fig. 3 the outer end of the fluke will be positioned substantially flush with the periphery of the casing l0 and will be resting on the curved wall 25. The body of the fluke is of a width to slidably fit in the groove 22, thus insuring a definite path of travel for the fluke to and from its position in the casing.
It will be noted that this stake is provided with three like fiukes equally spaced apart so as to provide suitable anchorage at the bottom of the housing. Ihe fiukes when extended are disposed at substantially right angles to the axis of the housing, thus providing good engagement with the unbroken earth structure adjacent the stake.
When the flukes are extended as shown in dotted lines in Fig. 3 it will be noted that the head of the fluke rests in the groove BE] of the nut while the outer curved surface of the body thereof rests against the curved portion 26- otthe groove, thus insuring a secure anchorage for the fluke as force is exerted to pull the istake from the ground.
When the stake is properly set the anchoring cable or guy wire is passed through hole 16 and recessed. It is considered best practice to drive the stake so that it will'be-in substantially parallel relation with the anchoring cable when-the ,lparts are-in the anchoring :posit-ion.
What I claim as new and desire to protect by Letters Patent is:
