WELL-RIG.

Specification. of Letters Patent.

Patented Aug. 14, 1906.

Application filed July 12.1906. Serial No. 269.288.

To a whom it may concern:

Be it known that I, SAMUEL STEPHEN STROTMAN, a citizen of the United States, and a resident of Haynie, in the county of Clarion and State of Pennsylvania, have invented a new and Improved Well-Rig, of which the following is a full, clear, and exact description.

This invention relates to Well-rigs; and it consists, substantially, in the details of con struction and combinations of parts hereinafter more particularly described, and pointed out in the claims.

The invention has referencemore especially to oil or gas well rigs; and one of the principal objects thereof is to overcome numerous disadvantages common to many other structures hitherto devised for similar purposes.

A further object is to provide a structure of this kind which is simple in its embodiment and comparatively inexpensive to install, besides being thoroughly effective and reliable in operation, strong and durable, highly resistive .to working strains from all directions, and possessing the capacity for long and repeated service.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view, partly in section, of

.a well-rig embodying my improvements. Fig

2 is a sectional top plan view thereof, and Fig. 3 is an enlarged sectional view taken on Fig 4 is a side elevation of a Well-rig, showing my special means of bracing the same.

Before proceeding with a more detailed description it may be stated that in the form of my improvements herein shown I employ a well-rig of special construction, comprising special means for bracing the structure in the direction from whence proceeds the driving force for the movable operative parts of the structure, special means being also employed for controlling the reel upon and from which is caused to be wound and unwound the line or cable for the bail or other well-tool. The several parts of the structure are easy of access, adjustable, and smooth-running in operation, and while I have herein represented my improvements in a certain preferred embodiment it will be understood, of course, that I am not limited thereto in precise detail, since immaterial changes therein may be resorted to coming within the scope of my invention.

Reference being had to the drawings by. the designating characters thereon, 1, 2, and 3 represent cross-sills of a suitable base or platform for the framework of the structure, connecting with which are the longitudinal sills 4, 5, and 6, the said cross-sills 1 and 2 being sunken or embedded within the ground for successively decreasing depths or extents, while the said cross-sill 3 rests practically upon the surface of the ground, thus giving to the longitudinal sills 4, 5, and 6 a downward inclination in the direction of the outer ends thereof, connection being had at 7 in any suitable way between the outer ends of the longitudinal sills 4 and 6 with the inner ends of longitudinal brace-rods 8 and 9, the outer ends of which may be connected in any suitable way with the platform, (not shown,) upon which is mounted in the usual way the engine or other motor (not shown) for imparting driving motion to the movableoperative parts of the structure. Mounted upon the base or platform near one side of the structure and preferably directly above the crosssill 1 is a jack-post 9", connected with which is the inner end of another longitudinal bracerod 10, the outer end of which may also be connected in any suitable Way with the platform of the engine or motor, and in virtue of the employment of these brace-rods 8 9 and the said brace-rod 10 it will be seen that a very firm bracing for the structure is derived in the direction from whence proceeds the driving force for operating the movable parts of the structure.

Supported in suitable bearings 1 1 therefor at the upper part of the ack-post 9 is one end portion of a transverse shaft 12, the other end portion of which is supported in a corresponding bearing 13 therefor, mounted in suitable position on the said cross-sill 1, said shaft having rigid therewith a differential drive-wheel 14:, having circumferential bandfaces 15 and 16 of different diameters, the band-face 15 having applied thereto a driving band or belt 17 fromthe engine or other source of power and the band-face 16 having applied thereto in like manner but in the opposite direction another driving connection or belt 18, which extends to and about the circumferential band-face 19 of a reel-turning pulley 20, the remaining circumferential face 21 of which is left free to be engaged by the inner curved face of a brake-shoe 22, in-

' tersected at the upper end thereof by the end of the inclined member 23 of a bracket 24, having a base member 25, the end of which is secured to the lower end of the said shoe 22 by means of a bolt or rivet 26 or in any other suitable way, the said bracket or members being longitudinally movable, so as to permit adjustment forwardly or rearwardly of the said shoe with respect to the band-face 21 of the reel-turning pulley 20. the said bracket may be strengthened, if de sired, by means .of a suitable brace 28 .or in any other way, and it should be stated that the reel -turning pulley 20 is rigid with the reel or shaft 29, upon and from which is caused to be wound and unwound an ordinary line or cable .30, passing upwardly over a guide-pulley .31 therefor, suitably mounted in bearings at the side of one .of the members of an ordinary derrick 32, such as is commonly employed in structures of this kind, said line or cable 3:0 extending downwardly within a well tube 33 and to the lower end of which may be f-astenedcthe bailer or other well-tool. (Not shown.) =One journal or end portion of the said reel or shaft 29 has its bearings at 34 in a lever .35, the lower end of which is loosely mounted on a rod 36, extending transversely of the structure and supported by the vertical member'37 of a shoe 38, having therein a longitudinal slot 39, permitting of the necessary forward and rearward working movement of the said lever Said shoe is provided with longitudinal slots 40 and 41 to enable the same to be adjusted in one direction or the other upon fasteningserews 42 and 43, passing through said slots and-secured to a table 44, upon whichthe shoe is mounted orsupp orted. Theother j ournal .or end portion of the said reel or shaft '29 has its bearing in an upright member 45,, mounted in any suitable manner on the table 44 in al inement with the said lever3'5, and connecting with the upper part of this upright member is an outwardly and downwardly inclined brace 46, the lower end of which is pivoted at 47 to a supporting-beam 48 therefor, located on the table 44, and the upper end portion of which brace is formed with a diagonal slot 49, through which extendsa pin 50, entering the side of the said upright member 45. (See Fig. 3.) The upright member is also provided near its lower extremity with a vertical slot 51, throughwhich extends a pin 52, which enters the side of the hereinbeforementioned beam 48, and it will thus be seen that by loosening the pins 50 and 52 the upright member 45 may be adjusted both vertically and horizontally with respect to the table 44 and brace 46, the latter, it being understood, being normally capable of being shifted on its pivot 47 into conformity with any shifting of the lever '35.

Movably supported on a pivot 53, extend ing between the sides of a longitudinal slot The members of 54, formed in an extension 55 of the shoe 38, is the lower endof .a hand-lever 56, connected with which at 57 is one end of a connectingrod 58,,the other end of which is in movable connection at 59 with a swinging rod 60, the

lower end of which is in movable connection at 61 with a suitable support 62 therefor extending from the jack-post 9 or any other stationary part of the structure, the upper end of said swinging rod being in movable.

connect-ion at 63 with one end of 1a reverse-lyextending-connection-rod 64, the other-lend of which is in movable connection-M465 with the upper end of the aforesaid lever35. It

will thus be seen that when the hand lever' 56 is in the position shown in Fig. 1 .thexdlixV- ing connection 18 between the differential drive-wheel 14 and the reel-turning pulley '20- will be taut, and therefore the ldesiredmotion will be communicated to the shaft or reel 2/9, by which to cause the line or icable39 to bie' wound thereon to raise or elevate the bailer or other tool within the well-tube 33. moving said lever slightly in the idirectionoi the reel-turning pulley 2,0 the shaft or reelt2z9. will be free to rotate in either ldirect'ion and.

consequently the line or cable will be caused to unwind from the reel or shaft 29 by theweight of the bailer or other w.ell-tool., which descends vwithin the well-tube in an obvious. manner, the speed of descent thereof being controlled or regulated by the amount of trio-i tion taking place between'the brake-shoe22- and the face 21 of the reel-turningpulley20.

This pulley 20 is provided with an annuiar flange 66 for preventing the drivingconnection 18 therefor from slipping onto the face 1' 21 thereof, and it is apparent that by moving the lever 56 to a suflicient extent farther the direction of the pulley 20 the desired:

braking relation of the brake-shoe '22 with the said face 21 thereof may be refliected. In

other words, by proper adjustment or swing ing of the said lever :56 the brakeshoe 22 may be made to so engage with the face '21 of the reel-turning pulley 20cas to maintain the reel or shaft 29 stationary with sufficient:

slack in the driving connection 1:8 to permit of the continuous operation of the drive wheel 14 without in any manner affecting for the time being the said reel or shaft 29.

In order to prevent sagging of the driving connection or belt 18, I preferably provide beneath portions thereof suitable supports 67 and 68, which also cause said driving connectionor-belt to remain inactive or loose :(by slight pressure thereon) .at such timesas the reel or shaft 29 may not be in motion, said supports being held in the desired position by means of upright members, (indicated at 6'9 and 70.)

From the foregoing it is thought that the} construction and operation of my improved well-rig structure will be thoroughly understood, and it will be seen that the same pos-v sesses many advantages in point of economy, as well as in other respects hereinbefore mentioned.

Supported on the base or platform are the usual upright frames 72 and standard 73, carrying at its upper end the pivoted beam 74, a further description of which parts is deemed unnecessary herein.

To enable the described adjustments of the bracket 24 and brake-shoe 22 to be effected, a slot 75 is formed in the table 44, through which extends the bolt 26, having thereon the tightening-nut 76.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A well-rig comprising a base inclined downwardly at one end and having braces connected to such end and inclined upwardly therefrom. y

2. A well-rig comprising a base inclined downwardly at one end and partially embedded in the ground, and having braces connected to such end and inclined upwardly therefrom.

3. A well-rig comprising a base inclined downwardly at one end and supporting a jack-post, and braces connected to such end and inclined upwardly therefrom and braces connected to the jack-post and extending horizontally therefrom.

4. A well-rig comprising a base inclined downwardly at one end and partially embedded within the ground, braces connected to such end and inclined upwardly therefrom, said base supporting a jack-post and braces connected to the j ack-post and extei1d- 7 ing horizontally therefrom.

5. A well-rig comprising a base inclined downwardly at one end and partially embedded within the ground having braces connected to such end and inclined upwardly therefrom, said firstnamed base embodying cross-beams and longitudinal beams.
