Application for reissue June 16, 1937, Serial No. 148,613
9 Claims.
The invention provides novel and unique support and guide means for a reciprocating power rod line transmission, such as used in oil fields for operating a number of pumps from a given source of power.
The invention provides a device of simple, sturdy and durable structure, involving few parts and not susceptible of disarrangement when properly installed, or tothe collection. of moisture, sand or other foreign matter tending to detract from its efliciency or shorten its period of service.
While the drawing illustrates a preferred embodiment of the invention, it is to be understood that in adapting the same to meet specific needs and requirements, the design may be varied, and changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.
For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawing hereto attached, in which:
Fig. 1 is a vertical, central sectional view illustrative of an embodiment of the invention;
Fig. 2 is a sectional detail on the line 2-2 of Fig.
Fig. 3 is a vertical detail section on the line 3-3 of Fig. 1;
Fig. 4 is a side view, the upper end of the post being in section;
Fig. 5 is a. sectional view of a bearing on the line 5-5 of Fig, 6;
Fig. 6 is an end view of the bearing;
Fig. 7 is a perspective view of the idler assembly; and
Fig. 8 is a transverse sectional view of the head on the line 8-8 of Fig. 1.
Corresponding and like parts are referred to in the following description and designated in the several views of the drawing by like reference characters.
The head preferably consists of a casting embodying a fork 24 and shank ll. Boxes III are formed at the upper ends of the fork members. Extensions 23 surmount the boxes and their upper edges slope outwardly and downwardly to prevent lodging of the rod or transmission line 23 on the boxes when displaced from the pulley 8, thereby preventing injury to the head by reciprocation of the rod in contact therewith. The boxes III are approximately square and disposed with the diagonal axes vertically and horizontally, as shown most clearly in Fig. 3, presenting a diamond-shaped outline. The boxes are closed except at the inner and the top sides which are open to facilitate removal or insertion of the square bearings 18 therein. The lower inner corners of the boxes are cut away at Hi, to insure aligning 0f the bearings. l8 and to provide clearance for moisture, sand, or other foreign matter that may find its way into the boxes.
Hollow ribs 28 brace and strengthen the fork head 24 and boxes It and connect with the cut away portions IE to carry off any matter tending to accumulate. A raised. seat I9 is formed upon the inner face of each lower side of the boxes ID to engage the bearings l8 and prevent any play thereof. This also results in clearance for the escape of any moisture, sand, or other foreign matter that may find its way into the boxes. The fork 26 is of channel formation for strength and lightness.
The bearings l8 are square and are of appreciably smaller transverse area than the area of the respective boxes, whereby said blocks are loose therein and capable of relative bodily movement up and down as well as from side toside for self-adjustment of the blocks to compensate for wear and may be of any preferred material, such as processed wood which resists wear and does not require frequent or excessive lubrication. The axle openings 2| are closed at their outer ends to exclude the entrance of moisture, sand, and other matter. The extensions 23 are located at the top and at the upper edges of the open sides of the boxes and serve as guides to facilitate the placing of the pulley 8 and bearings l8 in position.
The pulley 8 is grooved to receive the rod line 22 and is fast to the axle l3, being preferably cast thereon and prevented from displacement by projections ll formed on the axle and embedded in the pulley. Plates or washers 9 at the sides of the pulley 8 close the outer ends of the axle openings 2| in the bearings l8, and sustain the lateral thrusts of the pulley.
Tubular posts l4 are positioned at intervals along the length of the rod line and receive idler heads and pulleys. The shank I I of each idler head telescopes the post and is formed at its lower end with projections l2 and at its upper end adjacent the base of the fork with tapering projections l2a which wedgingly engage the upper end of the post to hold the head in place against any movement.
It is noted that the head is a one-piece structure and being of channel formation is light and strong. The extensions 23 function as guards and guides in the manner stated, besides bracing the boxes Ill. The form of the boxes Ill results in preventing displacement of the bearings and pulley by reason of the inward and downward sloping of the lower sides, as best shown in Fig. 3.
I claim:
