l My invention relates to new and useful improvements in cable bearings for walking beams, often spoken of as beam hangers.

One of the objects of the present invention'is yii to provide a device ofk the character described especially designed for application vto a walking beam, and furthermoreto so constructr the beam hanger or cable bearing that there is no possi bility of a parted rod or vtubing being droppedl within the hole shouldlthe wire cable break vonj either side of the hangen y As is well known in the pumping o ffwells, es-

pecially deep'wells, a walking beam iscommonly y employed, which is pivoted to. a support, the

power being applied at one end andthe. beamr hanger or cable bearingbeng supported at the other. Operated byther cable in the hanger isV the pump rod or pump polish rod, which recip-v rocates in a stuffing box, and, Vof course, itjis necessary. that the pump rod operatejin a y verticalmanner. Q

Still another object of the invention, therefore, is to provide a beam hanger that isv strong' in construction, easily installed, so dsgnedthat ity 5 insures a straight' lift stroke, and finally that shouldone bight of the cable that supports the rod break the other bightof the cable Iwill be prevented from leaving the cable bearing, thus v adding a further factorof safety.`

Still another object of the invention is to pror` vide a beam hanger in which all joints may be electrically welded, which beam hanger may be readily and conveniently fastened to a block on the distal end of the walking beam,fand which beam hanger may be quickly swung back to clear the hole when pulling or removing the rods or tubing.y

With these and other objects in view', themvention consists in certain new and novel ar rangements and combination of parts, asnwill be hereinafter more fully described and pointed out in the claims.

Referring now to the drawing showing a pre-v ferred embodiment,

Fig. 1 is a fragmentary side elevation of my improved beam hanger as secured to the end of a walking beam;

Fig.v2 is a front view thereof;

Fig. 3 is a sectional .View of a bracing clamp taken on the line 3-3 of Fig. 1, looking in the direction of the arrows; n

Fig. 4 is a detail of one of the safety clamps provided, partv being broken away for the sake of clearness;

Fig., 5., is adetail sectional View vof rthe beam hanger taken onLthe line 5-#5 of Fig. 2, i Referring now to Figs. v1 and 2 showing', a pref. ferred embodiment, tliere is shown a "fragmen tary portion I yofa walking beam which, as is well known, will Ibe pivoted to a support y(not shown). To the proximal end of the beam will be applied power for operating the same, lthis connectionnot being shown as it is in common .use and well known. v Thisbeam is preferably made of steel andnmay be fabricated, consisting of the channels 2; and 3, as shownin. Fig. 2, andmay have braces, as shown atv 4, along itsy length.v v

There will bel noticed near the endof the'beam is provided a block 5 which is securely bolted, as

at 6, to the outstanding ilanges beams, and it is this block ,that forms a cradle or bearing for a pintle or trunnion 1, fromwhich '1, 2'0

is to be hung the beamlha'nger or, cable bearing.A After the trunnion hasr 4been .properly placed within the blockfit may be Arigidly held in-position by the relatively long bolt 8 that, in turn, may be'held'at its lower end by the plate 9, as maybe seen inthe several views.

Referring now for the moment tothe, beam hanger proper, it will, be vseen that it consists of two arcuate cable guide arms or bearings l0 and I8', whose center wouldbe the pivotal point ing electrically weldedlto the respective plates Il and' i2. These latter platesfare provided with .openings through which thel opposite endsv of` the trunnion4 will passl to `*thus 'adjustably support the beam hanger.

' Also v.extendingin an arcuate manner above the trunnion'l maybeseen vthe plate orcro'WIl of the walking beam,vthese arms land |0.be

l3 over which will passthecable I'4,.fshortly to be described'. Supporting'thiscrown l3may be seen the braces/l5 which bear at, their lower ends on thep'intle y'Lf .I may alsoprovide :the

1 twoeye bolts i6 vto notionly hold-.thefcable ,on5

thecrown but to 'hold the cablein position.

Referring now for the moment to the cable I4, it consists of what might be termed two bights Hl' and i4. It will be noticed that one bight I4 is passed through anopening l1 in the one end of the trunnionfwhile the'bight I4 passes through a like opening I8 in the opposite endof the trunnion. v

To prevent the loosing or possibility 'of drop'- ping the rods or tubing, I provide two clamps 'Y i9 and a description of the one is a description of the other. One clamp is secured to the bight I4 just above the trunnion 'l `and is locked in are two of these braces place by the nuts 20, there being provided a small plate 2| over the ends of the U-shaped member 22, so that on a drawing up of the nuts 20 the cable will be securely clamped in position.

As heretofore mentioned, two of these clamps are provided, so that should the bight I4' of the cable part anywhere up to the trunnion the remaining bight' I4" of the cable will still remain fastened to the pump polish rod and prevent the loss of the tools or parts. In Fig. 2 I have shown in dotted lines a pump polish rod and the upper extremity of a clamp which, in turn, will be secured to the respective bights of the cable. The ends of the cable may pass around this clamp (not shown) and then be held by the clamps C. Of course, various forms of clamps might be attached to the ends of the cable but this does not form the subject matter of thev present invention.

Near the lower ends of the guide arms I and I0' is secured a ,bracket 23 to which is pivotally connected, as Aat 24, the brace rod 25 which, in turn, 'is provided with aslot 26 at its upper end which passes over a bolt 21 mounted in a clamp 28. This clamp is shown in detail in Fig. 3 and consists of a body portion with the lower leg 29 and the upper portion 30 which is provided with a slot 3| in which its the ange 32 of the walking beam lI. It will be understood that there 25 and likewise, of course, twoclamps, one on each side of the walking beam extending to the guide arms. The clamps 28, after the machine has been placed in position, will be moved along the walking beam to adjust the guide arms or beam hanger through lock bolts 33, as will be readily understood. The guide arms may be strengthened by cross braces, such as at 34, and on the outer faces of these arms may be seen the guide pins 35, a pair being shown near the lower ends of the said arms and one about midway the arms directly in front of the brace 34.

As heretofore mentioned, the parts are all preferably electrically welded, such as the saddle bearing or brackets 23,the braces 34, the guide arms I0 and l0', and the supporting plates Il and I2, thus providing a fabricated structure of great strength From the foregoing, it will be seen that with my present beam hanger, it may be readily attached to the end of any walking beam and especially toa steel fabricated beam like that illustrated and that the angle of the hanger may be quickly and readily adjusted by a movement of the small clamps `28 which may then be locked in place. Again, when it is desired to swing the beam hanger out of the way, the rods 25 will be slipped off the bolt 21 .to thus allow the rods or tubing to be pulled from the hole without interference with this beam hanger.

IFinally, the supporting cable is in two bights, each of which passes through the supporting trunnion, with further safety means in the way of clamps above the trunnion, so that if either bight should break the remaining bight will still support the rod.

Many slight changes might be made in the construction hereinbefore set forth without in any manner departing from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A beam hanger including a mounting adapted to be secured on a walking beam, a trunnion in said mounting, arcuate guide arms hung near the opposite ends of said trunnion, means secured near the lower ends of said arms and adapted to also be secured to said walking beam to position the hanger, a crown extending above said trunnion, a cable supported on said crown and ex tending down said arms, the lower ends of said cable adapted to be secured to a clamp, and means secured to the cable above the trunnion to prevent the entire cable from slipping from said crown should one of the bights of the cable be parted.

2. A beam hanger including a trunnion, means for mounting the trunnion on a walking beam, a crown above said trunnion, guide arms hung from said trunnion, a cable resting in said arms and passing through said trunnion and extending across the crown thereof, and means secured to the cable above thetrunnion to prevent the cable if broken from passing entirely through said trunnion.

3. In combination with a Walking beam having outwardly extending fianges, a mounting on the end of the walking beam, a trunnion in said mounting, a crown above said trunnion, the said trunnion being perforate near its opposite ends,

guide arms supported from said trunnion, means clamped to the flanges of said walking beam for adjustably positioning the guide arms with angular respect to the walking beam, a cable threaded over said crown andthrough the trunnion and extending down along said guide arms, and means above the trunnion for preventing the cable from leaving said hanger even though one bight of the cable should become parted.

4. In combination with a fabricated metal walking beam, clamps adjustably secured along said walking beam, a trunnion mounted near the outer end of the walking beam, means for holding the trunnion in place, a crown supported by the trunnion, cable bearings in the form of guide arms, means for bracing the arms with respect to each other, braces extending from the lower portion of said arms to said clamps, a cable having its opposite ends threaded through said trunnion and supported on said crown, and further clamps secured to the cable above said trunnion to thereby prevent the loss of said cable.
