June 21, 1938. RD. HILL ROD LINE CARRIER Original Filed Feb. 4, 1935 I I J INVENTOR 'fliara BHi/l Patented June 21, 1938 UNITED STATES PATENT OFFICE ROD LINE CARRIER Application February 4, 1935, Serial No. 5,006 Renewed May 25, 1937 8 Claims.

This invention relates to well pumping apparatus and it has particular reference to supports for well pump rod lines.

The principal object of the invention is to provide a rod line support or carrier which will effectively eliminate the frictional wear to which these types of supports are subjected and. which is imposed upon the rodline or pull rod, such frictional Wear being eliminated by virtue of roller bearings upon which a roller is mounted to receive the rod line.

Another object of the invention is to provide an improved mounting constructed for the roller supporting the rod line and which mounting is provided with the rod retainer of simple and effective design and which is preferably cast integral with the mounting and by simple manipulation of the latter, the retainer will overreach the rod to prevent displacement of the latter in operation.

Still another object of the invention is to afford in the mounting a novel means by which the roller may be readily mounted for normal operation within the mounting.

With the foregoing objects as paramount, the invention has particular reference to its salient features of construction and arrangement of parts which will become manifest as the description proceeds, taken in connection with the. accompanying drawing, wherein:-

Figure 1 is a side elevation of the rod line carrier constructed according to the present invention.

Figure 2 is a side elevation, partly in section on lines 2-2 on Figure 3.

Figure 3 is a view on lines 33 on Figure 2.

Figure 4 is a View on lines 44 on Figure 1.

Figure 5 is a perspective view of the type of roller bearing used in the invention, and

Figure 6 is a plan View of the invention.

Continuing with a more detailed description of the drawing, reference is primarily made to Figure 1 wherein l designates the conventional type of tubular post, shown in broken lines and which is disposed immediately below the rod line in spaced relationship with other posts. These posts serve to retain the rod line carriers in proper relationship with the rod line.

The present invention is comprised of a mount ing which is preferably made in a single one piece casting having a tubular portion 2 which is received in the upper end of the tubular portion l. The upper part of the mounting is comprised of two vertically parallel arms 3, whose upper ends are turned abruptly inward and due to the angular deflections a and b on one side of each of the said arms 3, and which deflections are reversed to one another, an oblique slot is provided intermediate the inwardly turned ends 4 of the arms 3, due to the fact that the angular deflections a1 and b continue upwardly and over the top of the casting. Accordingly, the ends of the arms 3 overreach the longitudinal axis of the mounting and which fact serves to retain the rod 5 in the groove of the roller 6.

It will be observed in Figures 1 and 3 that the flat sides of the arms 3 are provided with webs l which extend from the shoulder 8 below the arms to a point well above the normal location of the axis 9 of the roller 6. The normal location of the axis of the roller 6 is shown only in Figure 1 since in Figures 2 and 3, the roller 6 is shown as being inserted into the mounting hence the axis pin I0 is spaced above the normal axis and in Figure 3, it is shown as being displaced preparatory to mounting the roller 6.

Intermediate the upper and lower terminal points of the web 1, there is provided a boss ll, extending outwardly from the common surfaces of the arms 3 on either side. These bosses provide cavities l2, serving as retainers or bearings for the ends of the pin In. It will be observed that in order to define the bosses II, the. webs I are each divided at a point midway between their ends and continue upward as two parallel webs, intermediate which there is an elliptical opening I3. This opening, while spaced above the location of the normal axis of the pin In, it nevertheless receives this pin in the position shown in Figures 2 and 3 and after insertion of the pin into the roller 6, the roller and pin are dropped to the position shown in Figure 1, in which position, the ends of the pin l0 repose at the bottom of each of the recesses I2 and unless the roller is lifted out or the mounting inverted, it is impossible to displace the roller 6 from its operative position shown in Figure 1. Neither is it possible to lift the rod line 5 from its position within the groove of the roller 6 without first lifting the mounting from post I, rotating the same to an oblique angle with respect to the rod 5 and again lowering the mounting or lifting the rod through the oblique slot defined by the inwardly turned ends 4 of the mounting. It will thus be seen that the invention is thoroughly effective in maintaining alinement of the rod line assembly without the possibility of the rod line becoming displaced from the pulley 6 of the carrier.

One of the outstanding features of the present inventions resides in the roller bearing 14 shown in detail in Figure 5. Conventional types of rod carriers and supports give little attention to frictional wear to which the roller or the rod line is subjected. Some types of rod carriers provide wooden blocks or rollers with wooden centers but these soon give way to frictional wear and must be frequently replaced or repaired. Also, conventional types of carriers are required to be frequently greased or otherwise lubricated and without this attention, they soon become worn and useless and the rod line falls out of alinement. a

The bearing I4 is suitably secured within a central opening in the roller 6 and the rollers of this bearing assume the weight of the rod assem= bly. It has been found in practice, that the roller bearing will give a considerable amount lot.

service even without lubrication and in remote points in the field diflicult of access, this feature is of considerable advantage inasmuch as the rod line carrier continues in service without being oiled,

Manifestly, the construction shown is. capable of considerable modification and such modification as is considered within the scope and meaning of the appended claims is also considered within the spiritand intent of the invention.

What is claimed is:

1. A roller support. for. surface pull rods comprising a. grooved roller having a bearing affixed to. its center and a pin extending therethrough, a mounting having a pair of arms in parallel relationship, said arms extending above the periphery of said roller and having alined openings intermediate the ends thereof and internal complementary grooves communicating. with said openings and terminating at a point below said openings tov receive the ends of .said roller pin, said arms being substantially in the shape of right angle triangles inversely disposed and having their ends turned inwardly to.-define. a diagonal slot to receive said poll rod whereby the latter will lie operatively between said arms. and in. the groove of said roller.

2. A rod line carrier comprising amounting having upwardly extending arms and having a rod receiving guide between, said arms, and. means forming an upright slot. between said arms above said guide extending in an upright plane at an angle to the upright plane of the guide.

3. A rod line carrier comprising amounting between said arms, and means forming an upright slot abovesaid journal extending in an upright plane at an angle to the upright plane of the journal to receive the rod line therethrough with the sides'oisaid slot arranged to hold the red line on the journal.

5. A rod line carrier comprising a mounting having upwardly extending arms and having a. rod line-journal arranged between the arms,

said arms having inwardly extending laterally overlapping projections, said projections being spaced apart transversely to provide an upright slot therebetween for the reception of a rod line.
