WEIGHT ELEVATOR FOR PULLING MACHINES.
Application filed April 22, 1926.
This invention relates to well drilling equipment and more particularly to portable types of drilling and pulling machines, and the primary object of the invention re sides in the provision of an arrangement, coacting with the operating machinery of such machines in assembling and pulling rods and tubing, whereby to avoid the necessity of constant operation of the machinery and to thereby alleviate the burden imposed thereon.
lVith the foregoing and other objects and advantages in view, the invention resides in the salient features of construction and arrangement of parts hereinafter defined in detail and illustrated in the accompanying drawings wherein,
Figure 1 is a fragmentary representation of a casing pulling or drilling machine, in elevation.
Figure 2 represents a plan view of the usual drum construction.
Figure 3 is a vertical cross sectional view of the mast, showing the weight therein, and
Figure 1- is a modified exemplification of the manner in which the cable sheave may be mounted in the mast.
Heretofore, in assembling rods, tubing and the like in wells, it was necessary that the machinery be almost constantly oper ated both forward and reverse to maintain control of the lines in lifting the said rods and tubing into position and lowering the same. 1
lVith this in View, particular attention is directed first to Figure 1, in which partial representation of a pulling machine 1 is shown, having a mast 2 of the usual tubular construction. This mast is collapsible upon the machine 1, from which position it is elevated for use to the position shown in the figure by suitable mechanism, not shown, nor forming a part of the present invention. A crown sheave 3 is mounted at the top of this mast, and about which a line 4 is passed, which latter has an end wound about the main drum 5, shown in Figure 2, while the opposite end thereof is used for handling tubing, rods, and the like.
In Figure 2, a plan view of the inclusive drum arrangement, the drum 5, not de parting materially from the conventional drum structure, is fixed to the shaft 5, as is likewise the shorter drum 6, the latter being preferably situated outside the frame Serial No. 103,871.
1 of the machine. While no restrictions are intended as to structure, a ratchet 6 is shown, particularly in Figure 2, which is also fixed to the shaft 5, and is engageable by the pawl 7, pivoted to the side of the frame 1. This pawl and ratchet mechanism, while in the present case is shown as being hand operated, may be of course modified so as to control the shaft 5 and drums 5 and 6 from other points on the machine by foot levers or other such means.
The line 4, which is the line used for handling various tools and the like, is wound upon the main drum 5 in a reverse manner to the position of the line 8 upon the drum 6, the reasons for which will be set forth presently.
Adjacent the top of the mast 2 a slot 9 is cut as shown, and in which a sheave 10 is adapted to be partially inserted, and held therein by bracket 11. The line 8 is mounted over this sheave and a weight member 12 is swung thereon by a pulley 13, after which the line 8 is secured to an eye bolt 14 in the wall of the mast 2, opposite the pulley 10, as in Figure 3. V The weight member 12 is of course selected to outweigh the bodies attached to the line l. Accordingly and in operation, the lines 4 and 8, being wound in a reverse manner about their respective drums 5 and 6, move in opposite directions, hence, an object attached to the operative end of the line 4 would move upward, simultaneous with a descending movement of the weight 12 within the mast 2, and vice versa.
A casing elevator or other type of grapple or hook may be applied to the end of the line i, and in lowering casing, tubing, rods or such equipment into the well for example, the elevator is engaged with the body to be lifted, and when the pawl T is released from the ratchet 6", the weight 12, being of greater weight than the body, would obviously descend within the mast, thus elevating the body to a position whereby it may be accessibly urged into the hole by an attendant. This movement is entirely controlled by the weight 12, no operation of the motor, not shown, is required. However, in order to return the weight 12 to the top of the mast 2, the motor must be operated.
It is readily apparent that through the assembly shown, operation of the machinery is reduced to a minimum, thereby rendering possible a material saving both in time and expense resulting from possible deterioration of machinery through constant operation under other conditions.
Figure 4t of the drawingsillustrates a modified example of the structure described, in that. the tying of the cable 8 tothe eye 13 is dispensed with. In this latter instance, the position of the bracket 11 is reversed and bolted as shown, thereby to dispose the pulley 13 nearer thec enter of the mast 2. The line 8 then placed over the pulley as before and securely ailizred to the weight member 12 as illustrated.
hile specific details of structure and function have been set out herein, itis not desired that the invention be limited thereto, and that certain changes and modifications may be resorted to without departing from the spiritand intent of the invention as set imrth in the iolloi'ving claims.
I claim:
