13 Claims.

This invention relates to new and useful immovements in walking beams.

One Yobject of the invention is to provide an improved walking beam having hangers for connec- 5 tion with the usual polish rod and pitman.

An important object of the invention is to provide a hanger for a walking beam arranged to be fastened to said beam and having its end projecting beyond the end of the beam, whereby bearing l supports for a polish rod or a pitman may be mounted thereon.

Another object of the invention is to provide a hanger for a walking beam comprising a pair of angular members engaging over the base flange l of the beam and secured thereto at the end of said beam, said members being spaced apart by the web of the beam so that a rod supported by the hanger may depend between the members.

Still another object of the invention is to provide an improved walking beamwhich is provided with top and bottom reinforcing plates at its central portion, each plate having openings therein spaced along its longitudinal axis, whereby welding or other material may be inserted in said openings to rigidly secure the plates to the beam.

A further object of the invention is to provide a plurality of vertical braces which are secured to the web and flanges of an I-beam and which extend between the flanges of said beam, whereby k the rigidity and strength of said beam is greatly increased.

A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure 1 is a side elevation of a walking beam mounted on a Samson post and constructed in accordance with the invention,

Figure 2 is a transverse vertical sectional view taken on the line 2-2 of Figure 1,

Figure 3 is a plan view of the beam and having part thereof broken away to show one of the hangers which are secured thereto,

Figure 4 is a longitudinal, vertical sectional view of the parts shown in Figure 3,

Figure 5 is a transverse, vertical sectional view, taken on the line 5-5 of Figure 3,

Figure 6 is a vertical sectional view taken on the line 6-6 of Figure 1,

Figure '7 is an isometric view of one of the hangers fastened on the end of thebeam, which is broken away, V

Figure 8 is a side elevation of a short piece of I-beam of which the brace `members are formed.

Figure 9 is a side elevation of another form of I-beam,

Figure 10 is an isometrical, sectional view of the same,

Figure 11 is a transverse, vertical sectional view, taken on the line II-II of Figure 10.

In the drawings the numeral I0 designates-an upright Samson post which may be of any suitable type. The type shown comprises four legs Il converging upwardly to form a pyramid. The usual bearing saddle I2 is mounted on the upper end of the post and receives the transverse fulcrum bar or rockerrl3 of a walking beam I4.

The walking beam is preferably formed of an I-beam I 5 which has its central portion reinforced by longitudinal plates or bars I6. The plates lie along the top and bottom of the beam and are provided with a plurality of elongated openings I1 extending therethrough. The openings are positioned along the longitudinal axis of each plate and when said plate is in position on the beam, these openings are in alinement with the vertical web I5 of said beam.

Welding, or other suitable material I8 is inserted in the openings and it is obvious that since,l the openings are directly above the web, each plate is secured by the welding to said web. If desired, each plate may be further welded to theI beam along its edges. By providing the openings I1, it will be seen that the plates become a part of the web of the beam and are not secured only to the flanges, as is the usual practice. The beam is reinforced and its strength greatly increased without the addition of a great deal to its weight.

To further brace the beam at its central portion, vertical braces I9 extend between the flanges of the beam on each side of the web. The braces may be positioned at any points near the center of the beam and are preferably welded thereto so as to provide an integral structure. It is pointed out that the rigidity of the beam is greatly increased and by providing both bars I6 and braces I9, a beam of lighter weight which can withstand greatly increased loads is formed.

On each end of the beam a hanger is provided. Each hanger comprises a pair of angular bracketsf or members 2 I disposed longitudinally of the beam and extending beyond the end thereof. Each bracket has its horizontal member overlying the base flange of the beam I4 and abutting the web thereof. The vertical member depends from the horizontal member contiguous to the base flange of the beam. I have shown the horizontal member welded to the web and the vertical member welded to the base flange, but the angular brackets may be fastened in any desired manner, although welding has been found satisfactory.

Vertical braces 20, similar to the braces I9, are mounted between the underside of the top ange of the beam and the top of the inner end of each bracket on each side of the web. These braces are preferably welded to the brackets, web, and top flange, and it is obvious that when a load is placed on the outer end of the brackets, the braces 20 will prevent such load from breaking the Weld and jerking the brackets from the beam.

On the projecting end of each hanger are mounted bearing boxes 22. O ne of these boxes has the upper end of the polish rod 23 journaled therein. The other box carries the ordinary operating pitman 24 for imparting motion from the power source (not shown) to the walking beam in the usual manner. It is pointed out that the web of the beam spaces the brackets sumciently far apart to allow the pitman and polish rod to depend therethrough and to freely swing therein.

It will be seen that a very efficient, simple and strong hanger is thus formed. It is pointed out that any suitable means for carrying the pitman and rod may be used on thehanger. 'I'he brackets being merely a pair of angular members, are very cheap, and by welding said members to the walking beam and bracing their inner ends with the braces 20, a sturdy support for the pitman and rod is provided.

on the top and bottom of the beam,

The Sampson post is provided with the customary headache post 25 on one side and the ordinary ladder 26 on the other. At the lower end of the legs, I provide foot plates or members 21. These plates have a tendency to work or breathe during the swinging of the beam, due to the load carried by the polish rod. For overcoming this breathing, I weld triangular brace members 28 to the plates and to the lower portion of the legs. These members may be formed by cutting a short piece of I-beam A diagonally, as shown in dotted lines in Figure 8.

It will be seen that the angular brackets which form each hanger are nothing more than short' pieces of angle bars and a very cheap and inexpensive structure is had. The welding of the longitudinal bars I6 and the hanger to the walking beam, as well as the welding of the braces I9 and 20 between the flange of the beam make for easy and quick assembling of the parts, and also provide a positive fastening means for the same. It is again pointed out, however, that the invention is not to be limited to welding, as satisfactory results may be obtained with other fastenings.

In Figures 9 to l1 I have shown another form of walking beam 30. This beam is constructed of a central longitudinal bar 3| which forms the web of the beam. A pair of longitudinal, angular members 32 are secured at the upper and lower l ends of the bar and each member has its vertical leg 33 contiguous to the bar and its horizontal leg S4 extending outwardly therefrom, whereby an I-beam is formed, as shown in Figures 10 and 11. The flat outer side of the horizontal legs 34 of the angular members is slightly beyond each edge of the central bar SI, whereby a central longitudinal groove 35 is formed in the upper and lower ends of the I-beam.

Thus when the reinforcing plates I6 are placed the openings I'I in the plates will be in alinement with the groove I1. The insertion of welding I8 through the openings I1 will enter the groove, and it is obvious that an integral structure of the plates and the beam is produced, whereby the plates and b-eam are permanently secured together.
