5 Claims.

This inventionrelates to asuspensionrack for suspending sucker rods in the derrick of an oil Well after removing the rods from the well.

An object of the present invention is to provide Va rack of this character provided with improved safety'means to insure against the possibility of dropping a sucker rod while in the act of 'beingengaged with the rack, means being provided whereby, assoonas a sucker rod has entered therack itwillbe impossiblefor the rod to drop through the rack, va safety feature distinguishing the present invention over known racks now inuse.

A further feature of the present invention is in providing the rack with means which will eliminate the danger-of setting the rack down upon th'e workmans feet when in the act of resting the-rack on the floor of the derrick.

Thefinvention together with its objects and advantages will bebest understood from a study of the following description taken in connection with vthe accompanying drawings wherein:

Figure 1 is a top plan view of the rack.

Figure 2 is a front end elevational View thereof.

Figure 3 is a transverse sectional view through the rack.

Figure 4 is a longitudinal sectional View through a slightly modied form of rack and Figure 5 is a fragmentary top plan view of the second form of rack.

Referring to the drawings by reference numerals it will be seen that the rack indicated generally by the reference numeral I0 comprises, in the present instance a substantially rectangular body plate II formed of iron or other suitable material. The body plate II is provided with a longitudinal entrance slot I2 located at about the longitudinal median of the body plate II. At opposite sides of the slot I2 the body plate II is provided with a series of laterally spaced transversely extending supporting teeth I3, which teeth, may extend either at right angles to the slot as illustrated in the form of the invention shown in Figure 1 or extend at an acute angle to the slot I2 and diagonally of the plate as shown in the form of the invention illustrated in Figures 4 and 5.

In both forms of the invention the teeth I3 which at their free ends terminate at the slot I2 are provided with upstanding terminals I4 forming stops. Also, at the entrance mouth of the slot I2 the body plate II has the corners thereof rounded as at I5 to facilitate the guiding and insertion of the sucker rods.

A combined guide and safety tooth IB extends longitudinally of the slot I2 .being integral at one end with the body plate I I as shown. At the free end thereof the side edges of the tooth I5, which latter is substantially T-shaped in cross section as shown in Figure 3 are rounded as at I'I to ,51,

cooperate with the edges I5 in guiding the sucker rods into the slot I2 at either side ofthe guide and safety tooth I6.

To support the body plate I I above the floor 'of the derrick, when the rack is in its lowered posilo tion, the body-plate II is provided on the under side thereof With short legs I8, the provision of which will tend to prevent injury to the workman as might occur, in the absence of such feet I8 when the'workmen are engaged Vin placing or lowering the rack to the loorof the derrick.

As will be understood the rack is adapted to be suspendedV in the derrick, the body plate I I adjacent the corners thereof being'provided withsuitablerapertures I9 for accommodating the eye bolt 20 through the medium of which the lowering and. raising cables 21| areiattached'to the plate v II of the rack, the bolts 20 and cables 2I being indicated by broken lines in Figure 2.

It will also be understood that the rack is adapted to be used in conjunction with the usual sucker rod elevators and transfer devices as are now generally used with the sucker rod hanger rack forming part of the present day oil-production equipment.

Normally the rack, in an elevated position, is suspended from the top of the derrick, and the sucker rod withdrawn from. the well by the usual elevator means and through the medium of the usual transfer device is introduced into the rack, entering the entrance slot I2 at either side of the safety and guide tongue or tooth I6, the sucker rod being thus guided from the slot I2 into the space between a pair of teeth I3, and when properly positioned with respect to the teeth lowered so that the upset end 22 of the sucker rod 23 may rest on the upper surfaces of the teeth in a manner to suspend the sucker rod from the rack as suggested in Figure 3.

As also clearly shown in Figures 2 and 3, the upper surfaces of the teeth I3 are inclined, sloping toward the side edges of the plate I I, and obviously by having the upper edges of the teeth so inclined there will be little or n-o tendency for the sucker rod to creep along the teeth toward 50 the free ends thereof. Also each pair of teeth may support several sucker rods the last sucker rod being arranged between the teeth being held against displacement by reason of the stops I4 as is thought apparent.

It will also be apparent that when the sucker rod has passed into the slot I2, the space between the free ends of the teeth I3 and the side edges of the guard and guide tooth I6 being such, said end 22 of the sucker rod cannot pass between said ends of the teeth I3 at the side edges of the tooth I6, hence it is practically impossible for a sucker rod to drop through the rack, the rack of the present invention being thus provided with a safety feature not possessed by existing racks now known to me.

Any important feature of the present invention is the utility and advantage of the guide tooth in acting as a means for guiding or steering or directing the rods to various points in the rack. By holding the rods or stand of rods against and in contact with the edge of the gui-de tooth, it is possible torslide the rod rapidly into or out of the rack without possibility of the rod or rods catching on the various ends of the teeth during the passage through the center of the rack to or from the various slots in the rack. Without such an elongated center guide tooth, the swaying motion of the rod makes it almost impossible to move them through the rack to the various slots without crashing into the ends of the supporting teeth. Thus, the center tooth serves both as a guiding edge on which to slide the rod an-d as a safety means to prevent rods from falling out of the slots.

Having thus described my invention, what I claim as new is:

1. A hanger for sucker rods comprising a body member provided with a row of teeth adapted to receive therebetween the sucker rod to be suspended from the rack, a single guide tooth bridging the spaces between the teeth at the free ends of the latter and spaced from said ends of the first named teeth sufficient to prevent dropping g of the sucker rod downwardly through the space between the rst named teeth an-d the guide tooth once the rod has been placed within the rack.

2. A hanger for sucker rods comprising a body member provided with a row of teeth adapted to receive therebetween the sucker rod to be suspended from the rack, a single guide tooth bridging the spaces between the teeth at the free ends of the latter and spaced from said ends of the rst named teeth suiicient to prevent dropping of the sucker rod downwardly through the space between the first named teeth and the guide tooth once the rod has been place-d within the rack, and supporting legs on the under side of the body of the rack.

3. A sucker rod hanger rack' provided with a single guide and safety tooth extending longitudinally of the rack and with a series of laterally spaced teeth at opposite sides of the first named tooth, the spacing of the second named teeth relative to one another and relative to the first named tooth being such as to insure engagement of the upset end of a sucker rod therewith in a manner to prevent total passage of the sucker rod downwardly through the rack after once placed therein.

4. A sucker rod hanger rack comprising a. body member having an entrance slot, rows of laterally spaced supporting teeth at opposite sides of the slot, said teeth extending transversely and thel spaces between the teeth opening into the slot,

and a single guide tooth extending longitudinally' of the slot and having the side edges thereof spaced from the free ends of the iirst named teeth.

5. A hanger rack for sucker rods comprising a body having a longitudinal entrance slot and a series of diagonally disposed spaced teeth at opposite sides of the slot with the spaces between the teeth opening into the slot, and a single guide tooth extending longitudinally of the slot and having its side edges spaced from the free ends of the first named teeth as and for the purpose specied.
