This invention, relates to means. for sus pending lengths of sucker rod such as are used in oil wells and the like, the suspension means being'mounted in the upper part.

of the well derrick and engaging the lengths of sucker rod so as to therefrom 1n the derrick;

suspend the latter and it is the object of the invention to provide safety means for engaging the suspended sucker rods so as to positively prevent from theirsupport.

The safety mechanism is particularly displacement thereof adapted for use in connection with suspension means comprising a rack, having a plurality of slots in its edge, so that one or more lengths of sucker rod may be received in each slot with the enlargements at the ends of the sucker rods resting upon the walls of the slots for supporting the rods;

itbeing understood however device 15 also adapted for that the safety general, use n connection -with any type of suspension means for sucker rods or the like.

The invention will be from the following panying drawings,

Fig. 1

readily understood description of the accom-- in which: 1s a vertical section through a well derrick showing the improved rod rack mounted therein.

Fig. 2 is a front elevation of the rod rack partly in vertical section.

Flg. 3 1s a transverse 33 of Fig. 2.

Fig. 4: is a section, on the line fragmentary front elevation of a rod rack, partly in vertical section and showing a modified form of the invention.

In the drawingsI have derrlck at 1, .the particular said derrick forming no,

shown a well construction of part of this nvention. The rack forv supporting lengths of sucker rod 2 is suspended. in said which may be suitably conby a cable derrick nected to the crown block l. k

In the embodiment of the invention ill-ustrated, the rod rack comprises a disc 6 extending inwardly having radial slots from its outer edge, turned peripheral lips and 7 provided with upbetween the slots.

A suitable supporting connection is provided between disc 5 and the cable 3, which in the present instance prising a tripod 8 the disc, and a hook is shown as comextending upwardly from 9 supported by said tripod and adapted to be engaged by the cable.

The sucker rods 2 which are to be suspended from the rack ar e elevated in usual possibility of accidental suiting in the .alinement with the respective manner until the coupling enlargements 10 zit-their upper ends are above disc 5, and the rack having been turned to position. any desired slot. 6.0pposite the sucker'rods, the latter are pulled over into the slot and are then lowered until their coupling enlargements rest upon disc 5, thereby maintaining the sucker rods suspended in the derrick after the elevator has been, disengaged therefrom.

lVhen the sucker rods are thus suspended from the rack, the lips 7 at the peripherv of disc 5 will engage the coupling enlargement 10 of the outer rod in each slot,'.in, order to prevent accidental displacement of the rods from the slots; but since these lips do not provide a positive lock for retaining the rods in the slots,.there is always the displacement, redropping of a length vof sucker rodand the probability of serious 1n ury. 1 I

The present invention-provides positive means for locking the-sucker rods relative to their supporting rack. As aninstance of this arrangement engaging means 'in rack, are mounted on said rack and are adapted to be received around the sucker rods in the respective slots, so as to prevent outward movement of the rods in the slots and thus maintain a positive suspension for said rods.

The engaging means illustrated in Figs. 2 and 3, comprise elongatedclosed, loops 11., of asize to be received over the ends of all. the sucker rods in any one slot of the rack, said loops being preferably suspended by short chains 12 from an annulus l3 which is mounted on the rod rack above disc 5. When a sucker rod'held in. its slot by a loop 11, is to be withdrawn, the loop is first removed from the rod and positioned over the ends of the remaining rods in the slot, and a usual elevator is then connected to the released rod for lifting it from its slotand lowering it into the .bore of the well.

A modified form of engaging means illustrated in Fig. 4, comprises hooks 11 connected to annuius 13 by the chains 12, the shanks of said-hooks beingof length to permit them being hooked around the outer sucker rods in the respective-slots of the rack,"in order to lock all of said sucker rods in the slots as previously described.- The hooks are preferably held against lateral displacement and consequent disengagement from the sucker rods, by lugs 14 depending from the outer ends of the hooks and adapted to be received in slots 6 when the hooks are in operative position. By the hook arrangements as thus described, when a sucker rod is to be Withdrawn from the rack the usual elevator is first connected to the sucker rod, and the hook is then disengaged from the sucker rod held by the elevator and hooked around the remaining rods in the slot; 1 It will thus be seen that the rod which is being withdrawn is never tree for accidental dropping, and the remaining rods in a slot, even if they catch upon the rod which is being withdrawn, are positively held against displacement from their slot.

The annulus 13 supporting the engaging means as thus described, is preferably mounted on a spider 15 having a bolt 16 depending from its center through an'aper-V hire in disc 5, the spider being held in place by nuts threaded onto the bolt in usual manner. A further support for annulus 13 is preferably provided by projecting the legs of tripod 8 through suitable bores 17 formed on said annulus, the legs of the tripod being detachably connected to disc 5 by nuts threaded onto the ends of the legs, in order that the parts may be thus assembled. The supporting annulus is thus positively fixed relative to the rod rack, so as to aline engaging means 11 or 11 With the respective slots 6, and permit said engaging means to be readily received around the sucker rods in the respective slots.

It will thus be seen that I have provided extremely simple but positive means for holding sucker rods or the like against displacement-from 'a support for the same, said engaging means being applicable to either a slotted rack as described, or any other type of suspension means; and that said engagiii-g may be readily mounted upon and secured to the supporting device, in position tor conveniently engaging or disengaging the sucker rods carried thereby.

I- claim:

1. Suspension means for sucker rods having coupling collars comprising a support having a recess, a retaining member, and a flexible connection between the support and retaining member, the recess of the support being adapted for lateral reception of a sucker rod with the Walls of the recess engaged by the coupling collar of the sucker rod so as to support the rod against longitudinal displacement independently of the retaining member, and the retaining-member being adapted to be 'removably received around a sucker rod supported in the recess so as to prevent transverse displacement of the rod.

2. Suspension means for sucker rods comprising a member having a recess adapted to reeeivea sucker rod st). as to hold the same against longitudinal displacement, retaining means adapted to extend across the recess in front of a slicker rod therein so as to prevent transverse displacement of the rod, and means on said retaining means adaptedv to be received in said recess for releasably holding the retaining means against movement laterally of the recess.
