UNITED STATES CONARD BAKER, 0F FLORENCE, KANSAS.

Ron CARRIER.

Application filed July 26, 1923. Serial No. 653,964.

Ta all whom it concern Be it known that I, CONARD BAKER, a citizen of the United States, residing at Florence, in the county of Marion and State of Kansas, have invented a new and useful Rod Carrier, or which the following is a specification. I,

Thisinvention aims to provide a means whereby rods of the vkind used in well drilling operations may be transported to some distance from the well casing, and be deposited on the ground or on a platform.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceed's, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows diagrammatically, a device constructed in accordance with the invention; Figure 2 is a side elevation of the carriage, a portion of the track appearing; Figure 3 is a section on the line 33 of Figure 2; Figure 4 is a top plan of the carriage; Figure 5 is a longitudinal sectional view wherein a portion of the track appears in elevation, a part of the mechanism mounted on the carriage appearing in the View; Figure 6 is a fragmental section on the line 6-6 of Figure 3; Figure 7 is a sectional detail showing the means whereby the support is actuated for adjustment.

In carrying out the invention, there is provided, as shown in Figure 1 a track 1 which may be of any desired length. the track having an upwardly inclined end 2 of any desired height. Figure 3 shows that the track 1 comprises main or side rails 3 and an intermediate or auxiliary rail 4. Near to the outer end of the track 1 (Figure 1) the intermediate rail 4 has a depression 5 shown best in Figure 5. Brackets 6 on the part 5 ot the intermediate rail 4 carry a substantially horizontal cam bar 7 having an inclined end 8.

A carriage 9 is provided, and is supplied with wheels 10 adapted to traverse the side rails 8 of the track 1. A plunger 11, in the form of a rack bar, is mounted for vertical reciprocation in the carriage 9. At its lower end, the plunger 11 is provided with a wheel 12 adapted to move along the intermediate rail 4 or the track 1. The plunger or rack bar 11 has a side projection 14, which may be a roller, the same being adapted to cooperate with the end of the cam bar 7 as shown in Figure 5, and being adapted to move along the lower edge of the cam bar.

The carriage 9 embodies an upstanding wing 17 provided with a slot 25. A depending latch 15 is pivotally mounted at 16 on the wing 17 and moves in the slot 25. A spring 35 is secured to the wing 17 and, cooperating with the latch 15, holds the latch in the posi tion delineated in Figure 3. A substantially horizontal tubular guide 18 is mounted at its inner end in the wing 17 and is located. below the latch 15. In the guide 18, an ejector 19 is mounted for right line sliding movement, the ejector embodying a stem 20 mounted to slide in a bearing 21 carried by the outer end of the guide 18. A compression spring 22 is located in the guide 18, about a portion of the stem 20 of the ejector 19, one end of the spring engaging the ejector and the other end of the spring engaging the bearing 21, the ofiice of the spring being to advance the ejector. As disclosed in Figure 6, the guide 18 has depending ears 23, wherein the outer end of a latch 24 (Figure 3) is pivoted at 26. The latch 24 has an upstanding projection 27 operating in an opening 28 in the lower portion of the guide 18. The latch 24, when in the position of Figure 3, serves to hold the ejector 19 retracted against the action 01' the compression spring 22. The vertically movable rack bar or plunger 11 is supplied with an elongated recess 29, wherein the inner end of the latch 24 is received.

hen the plunger 11 moves downwardly, the latch 24 is set free from the ejector 19, the ejector moving to the right in Figure 3, under the action of the spring 22. A means is provided for resetting the ejector 19, responsive to the upward movement of the plunger 11, and, having this consideration in mind, a bell crank lever 30 is fulcrumed for swinging movement, in a vertical plane, on the wing 17 of the carriage 9, the tulcrum for the lever being marked by the numeral 31. The horizontal arm of the bell crank lever 30 is engaged loosely in a recess 32 fashioned in the plunger 11. The vertical arm of the bell crank lever 30 terminates in a fork 33, straddling the guide 18, as delineated in Figure 6, the inner ends of links 34 (Figure 4) being pivoted at 36 to the fork 33, the outer ends of the links being pivoted at 37 to a cross head, through which the stem 20 of the ejector 19 passes, adjusting nuts 39 on the stem forming an abutment for the cross head.

The machine embodies means whereby the rods may be placed in horizontally spaced relation, on the ground or on a platform, as the rods roll out of the carriage 9. Sonsidering this part of the structure, it may be stated that the upstanding wing 17 of the carriage 9 has an outwardly projecting hearing 40 wherein a substantially horizontal shaft 41 is mounted for rotation; A pinion 42, housed within the bearing 40 (Figure 3) meshes with the rack bar 11 and is carried by the shaft 41. A ratchet wheel is mounted on the shaft 41 for rotation with the shaft and for sliding movement on the shaft longitudinally of the shaft. A bearing 44 is mounted on the frame work of the carriage 9. The frame work of the carriage and the wing 7 carry a transverse guide 45. In the bearings and in the guide 45, a shaft 46 is j ournaled, the shafts 46 and 41 being axially alined. The shaft 46 car ries a ratchet wheel 4'? cooperating with the ratchet wheel 43 and abutting against one side of the guide 45, as shown in Figure 4. A compression spring 48 surrounds a portion of the shaft 41, one end of the spring abutting against the bearing 40, and the other end of the spring abutting against the ratchet wheel 43, the function of the spring 41 being to hold the ratchet wheel yieldably engaged with the ratchet wheel 47.

A support is provided, along which the rods roll, transversely of the carriage as the rods leave the carriage. This support is in the form of a rack bar 49 (Figures 4 and extended laterally beyond one side of the carriage and mounted for longitudinal adjustment in the guide 45. A pinion 50, located in the guide 45, is carried by the shaft 46 and meshes with the support or rack bar 49. The support or rack bar 49 is downwardly inclined, transversely of the carriage 9, as disclosed in Figure 3. A loop-shaped frame 51 extends laterally from the rack bar or support 49, one end 52 of the frame being attached to the upper end of the rack bar, the frame terminating in an arm 53, disposed parallel. to the lower end of the rack bar and spaced vertically therefrom, as in Figure 3, the arm 53 of the frame terminating in a depending stop 54 located in alinement with the rack bar 49 and spaced horizontally from the lower extremity of the raclt bar, as Figures 3 and 4 will make evident.

Any suitable means may be provided for movii'ig the carriage 9 along the track 1. in Figure 1, the flexible element and a flexible element 56 are shown, the flexible element 55 being rove across an idler 5'? on the end 2 of the track 1 and the flexible element 56 being rove across an idle-r 58 on the outer end of the track 1, and being extended bachwardly to the carriage 9, the flexible element 56 being connected at 60 to the carriage and the flexible element 55 being connected at 59 to the carriage.

Assuming that the carriage 9. is on the upturned end 2 of the track 1 in a position adjacent to the drilling 01" pumping rig (not shown) the rod 61 is engaged between the upper end of the plunger 11 and the ejector 19, as shown in Figure 3, the ejector being advanced to grip the rod, under the impulse of the spring 22, the spring 35 holding the latch or retainer 15 in place above the rod 61. Through the instrumentality of the flexible element 56, the carriage 9 is moved backwardly along the track 1 and, ultimately the wheel 12 on the lower end of the plunger 11 rides downwardly in to the depression 5 of the intermediate rail 4 of the track, the plunger 11 being forced downwardly when the side projection or roller 14 on the plunger cooperates with the inclined end 8 of the cam bar 7, as shown in Figure When the rack bar 11 is carried downwardly, as aforesaid, the bell crank lever 30 is tilted on its fulcrum 31, the links 34 guiding the vcross head 38 forwardly on the stem 20 on the'ejector When the plunger 11 moves downwardly, the upper end of the plunger 11 is moved out of the path of the rod 61, and the latch 24 is disengaged from the ejector 19, whereupon the ejector moves to the left in Figure under the impulse of the spring 22, the ejector advancing the rod 61 and causing it to roll downwardly along the inclined support or rack bar 49. As the rod passes off the lower end of the rack bar 49, the de pending stop 54 on the frame 51 receives the rod and directs the rod downwardly upon the ground or upon any structure provided for the reception of the rod.

When the carriage 9 is advanced into the position shown in dotted line in Figure 5, the downward movement of the rack bar 11 causes a rotation of the shaft 41,by way of the pinion 42, but the ratchet wheel 43 does not, at the time, rotate the shaft 46 by way of the ratchet wheel, 47, the teeth of the ratchet wheel 43 clicking over the teeth of the ratchet wheel 47 and the spring 48 yielding so that the aforesaid movement of the ratchet wheels may take place. When,however, the carriage 9 starts to move toward the inclined end 2 of the track 1, responsive to the flexible element 55, the rack bar 11 moves upwardly'into the solid line position of Figure 5, as the wheel 12 traverses the inclined portion of the part 5 of the intermediate rail 41. Then, reverse rotation is imparted to the shaft 41 by way of the pinion 42 and the shaft 46 is rotated by the interengagement between the ratchet wheels 43 and 47, the pinion on the shaft 46 cooperating with the rack bar 49 to move the rack bar 49 and the stop 54: of the frame 51 a short distance to the left (Figure 3). The result is that when the carriage makes another trip toward the outer end of the track 1, the stop 5% is so positioned that, as a rod rolls from the machine, that rod will be spaced horizontally from the rod which has been previously deposited.

When the plunger 11 moves upwardly to the solid line position of Figure 5, the bell crank lever 30 the links 34 and the cross head 38 retract the ejector 19 into the position shown in Figure 3 and the latch 24 is swung upwardly until its projection 27 engages with the ejector 19, to hold the same retracted.
