United States Patent AO M ce TETHERING POST WITH A FREELY ROTATABLE i SWIVEL HOOK Michael Sullivan, Youngstown, Ohio Application April 24, 195,6, Serial No. 580,334

1o claims. (ci. 1194121) This invention relates to a tethcring device or staking means, rwhich has application in the tethering of animals in order to give them a limited range in which to move, but that will prevent movement beyond said range. An especial object of the invention is to prevent the entangling or kinking of the rope or chain that connects the animal to the post during movements of the animal `about the post as a center.

' Another important object is to reduce the cost of manufacture without reducing the advantages or the durability of tethering devices of this character, to thereby increase the volume due to decreased costs and .to thus permit sales at reduced costs. v HOther objects will appear hereinafter throughout the specification.

In the drawings:

Figure 5 isA a horizontal section taken on the lineA 5,--5 of Figure 4; and

Figure 6 is a view taken on the lines 6,--6 of Figure 2.

The present invention is an improvement on the, construction shown and described in4 my PatentYNo. `2,47-2,- 92,6, grantedV June 14, 1949.

In addition to structural improvementsof-the said patented deviceand others of like kir 1d 1 am ablev to reduce thecost of manufacture in the making of devicesof this invention over those of the. prior art. Usingpresent practices irinlakingA the said prior art devices, such as the device of my patent referred` to above, itfis rst necessary to assemble the parts together by anelectrical weldv ing operation, after which the units are sentby truck to aplating shop. The delay usually amountsto 'from l to 4`fweeks at this shop. Following the plating operation the Yarticles are returned-by truck'to the shop of` manufacture, then packed and shipped.

The presentinvention, however, obviates thisfloss of time inasmuch aesY the post, sleeves, disk, snap andrin'g,4 hereinafter referred to, all are received atthezshop after having been plated. It is possible to ship the device of 'this invention iinl krioekdown,A condition in, lots,V of about 200 posts,"400 sleeves, 200 snaps, 200 disks, and 200 rings, and no welding, stamping, or otherforming operations lare employed. inasmuchI as the posts and other elements refered..to aboveare shippedto the manufac-fy tutor, the box containingsaidposts need not bef opened, buttheright Aninnberof snaps, sleeves, disks andringsto go,\with the posts are plaeedein the box or similar con` tainer and forwarded to thenwholesaler. Thus it is not necessary for thel manufacturer vto perform any welding operations or, forward lparts -to a. plating compan, ,and

2,790,419 Patented Apr. 30, 1957 2 no to and .from 4the plating shop is necessary, -thereby saving .a considerable number of man hours fin .the manufacture and sa'le in the device ofV this invention.

Referring -to the drawings, particularly Figures 1-3 and Y5, the numeral 10 indicates a stake or post which may be driven into the ground. The stake is provided with a pointed end 12 and a head 14. A pair of

spaced sleeves

16 and 18 which encircle the stake Aare prevented from moving upwardly by the head 14 of the stake and from downward movement by the ground engaging plate or disk 20. The latter Vis slidably held from downward movement by the fricti'onal engagement of the retaining ring. 22, which is made of spring steel and is of a slightly smaller diameter lthan the post 10 which it frictionally engages. This ring is the Waldes Truarckl retaining ring made by Waldes Kohinoor, Inc. Y

`In the lform shown in Vthese figures, I provide a snap hook 24 having a reduced portion 26 and a head 28 adjacent the reduced portion, the said head bearing on

sleeves

14 and 16. A loop 30 encircles the post 10 and maintains the

sleeves

16 and 18 in separated position as shown, thus providing rotating surfaces both above and below the snap hook 24, which is thus spaced above thc ground by the sleeve 18 and disk 26. Loop 30, as shown in Figure 3, has an aperture 32 for reduced portion 26 of the snap hook. The snap hook thus is swivelled to the loop 30, which latter may be freely rotated about the pin 10. To the opposite end of the snap hook is attached the restraining device which as illustrated may consist of a chain 34 that is attached at its opposite end to the collar .36 of an animal.

In the form shown in Figures 4 and 5, 3S is the post having a pointed end `40 and a head 42. The separated sleeves are` shown at 44 and 46, while 48 is the ground Plate and' 50 the retaining. ring, preferably the same type of ring as shown at 22 in Figures 2 and- 5.

A stud 52 having. a head 54 is swivel'led in aperture 56. of the retaining'loop 58. that separates' the' sleeves 44 andv 46.` The opposite.y end or" the .stud 52 is welded or otherwiseA secured to the ring 60 that` forms one end of the; chain 62, whoseA 'oppositeend, not shown; may be secured toythe collar of the tethered animal, Ring 60, forming partrof the chain, 62,.is therefore' freely swivelledl to loop 60, which.` latter freely rotatesZ aboutthe post 38.

Inf both for-ins,` off` the invention theA sleeves, retainiiig loop and ground engaging plate are heldfrom" sliding otr` they Stake. byY tlie-y retaining, ring, shown inY detail? in Figurez5.l When this ring is-releas`edby a suitable tool, and' thmstakexremoved vfrom ,the ground, theparts noted; above maybe unthreadedfrom; theV post.
