To all whom t may ooacem.'

' Bje it known that l, JACK H. BEvEL, citizenof the United States, residing at Dallas, in the County of Dallas and State of Texas, have invented certain new and useful llmprovements in Measuring Devices, of which the following is a specification.

v'llhis invention relates to new and useful improvements in measuring devices.

The invention has particularly to do with measuring devices for use in ascertaining the depth of a' well and involves revolving measurin-g elements co-acting with the cable which is lowered into the well and operating a register whereby each foot of travel of the f cable downward is indicated;

In carrying out'the invention l provide a jointed framevcarrying a pair of measuring wheels having grooved faces and pro? vided with tension means whereby the cable is gripped between the wheels. One of the wheels operates a register once during each revolution thus registering the travel of the cable between the wheels. A particular feature is the arrangementv of the frame-which is provided with a hinged joint on one side opposite the'point where the cable passes between the wheels and a coupling joint on the other side having a removable fastening; whereby the frame may be broken open by removing the fastening, so that one' of the wheels will be swung away from the other, the cable released and an opening` provided -in the side of the frame whereby .the cable may be swung out of the frame,

or the frame removed from the cable. This arrangement affords a solid and substantial frame whereby the wheels are held in alinement when the frame is coupled together and also whereby the spring tension wheel does not lose its adjustment when the frame is broken. Supports are provided for the frame whereby it may be positioned on the top of a well casing and suitably held. The supportsmay be so constructed as to permit of adjustment for casings of various diameters.

The invention will be more readily understood from a reading of the Jfollowing' speelfication and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein: n Fig. 1 is a side elevation of a device constructed vin accordance with my invention,

and

Fig. 2 is` a plan view of the same.-

In the drawings the numeral 10 designates an elongated supportingl frame which comprisesra stationary section or yoke 11 and a swinging section or yoke 12. The yokes are joined together .at their ends which are at the center of the frame by a hinged joint 13. At the opposite side of the frame the ends of the yoke` are provided with intermeshing ears 14 perforated to receive a locking pin l5 whereby a coupling joint is had. When the pin l5 is in place the yokes` are connected and form va'rigid frame. When the pin is removed the yoke 12 may be freely swung on the hinged joint 13 away from the yoke 1l1 ets 22 on the sides of the yoke. rllhe springs are placed under tension by the screws 21 and thus exert pressure upon the airle through means of the stirrups whereby'the wheel 1 8 is placed under tension. A wheel 23 having a grooved face is mounted -on an axle 24: fixed inthe yoke 11. `'.llhe wheel 23 has a width less than that of the wheel 18 so as to be received relatively within the groove of the wheel 18. By this arrangement the cable A is moreeiiciently gripped between the grooved faces of the wheels as will be evident from Fig. 2. The spring tension devices exert suilicient pressure on the wheel 18 as .to cause the same togrip the cablein cooperation with the wheel 23.

The yoke l1 has its outer end fastened on provided with an ofset stepped bracket 27. A similar upright 251 is providedl for the yoke at the opposite end of the frame. The upright 251 has a shoulder 261 at its lower end and a stepped bracket 271. `Keeper plates 28 are secured to the outer sides .of the shoulders 26 and 261 and each platev car.- ries a setscrew 29. The shoulders 26 and 261 may rest on the upper edge of a well casing B so that the keeper plates will overhand the outside of said casing and may be fastened thereto by the set screws 29. For casings of smaller diameters angular brackets 30 are fastened to the stepped yportions of the brackets 27 and 271 by bolts 31 .the upper shouldered end of an upright'25 having a shoulder 26 at its lower end and and may be adjusted to form a jaw for eachv upright to fit over the upper edge of the casing, each bracket 30 being provided with a set screw '32 as will be obvious.

5 The upright 251 has at its upper end an outwardly directed support or bracket 33. An angular support or hanger 34 is fastened to the outer end of the yoke 12. A bolt 35 is passedthrough these partsfand receives a wing nut 36 whereby the yoke 12 is suitably fastened on the upright 251. It will be seen that through the agency of the couplingl joint involving the fastening pin 15 and the support at the end of the 15 yoke 12 employing the fastening bolt 35, the frame 10 will be rigidly sustained and the wheels 18 'and 23 properly held in alinement and caused to properly operate. It will be appreciated that if the parts of the 2 0 frame are not substantially fastened that there is a change for lost motion and a variation in the mechanism; also uneven wear would be had. 0n one side of the yoke 11 a suitable register 37 is mounted and provided with an operating finger 38 which projects into the path of a lateral pin 39 carried by the wheel 23.- Thus once during each revolution of the wheel 23 the pin 39 rides over the finger 38 and operates the register so as to record the revolutions of said wheel. The wheel may have such a diameter as to traverse a certain standard of measurement along the cable at each revolution, and thus a certain number of revolutions ofthe wheel 23 will total a measurement in feet Aand inches. It is obvious that various kinds of recording devices could be used and they form no part of the invention. When it 4.0 is desired to remove the cable it is merely necessary to withdraw the pin 15 and remove the bolt 35. After this has been done the yoke 12'may be swung backward and away from the yoke 11 whereby the ears 14 are separated and the frame broken, an opening thus being provided in the side of the frame through which the cable may be displaced. Thejroke may. be restored to position or it may be opened as described to receive the cable when it is desired to measure the depthof the well. yoke has been removed from the cable the measuring device may be removed from the well casing and likewise replaced when desired.

What I claim, is: 1. In a measuring device of the character described, a pair of substantially horizontal U-shaped frame sections having their open ends arranged innermost, a hinge joint connecting the inner ends of corresponding sides After the of th frame sections whereby one frame section may be swung horizontally with ielation to the other frame section and the frame section securely held against percepti ble vertical movement with relation to ,each other', a plurality of a ertured ears formed upon the inner end of the opposite side of one frame section, a plurality of apertured ears formed upon the inner end of the opposite side of the other frame section and adapted to interfit with the first named apertured ears, a pin adapted for insertion through the apertured ears so that they are securely locked together and one frame section held against vertical movement with relation to the other frame section, a friction wheel arranged within and supported by one frame section, a co-acting friction wheel arranged within and supported by the other frame section and adapted to move bodily toward and away from the first named friction wheel, yielding means to urge the second named friction wheel toward the first named friction wheel, a register supported upon one frame section near one friction wheel and actuated thereby, and supports attached to the outer ends of the U-shaped frame sections and depending therefrom.

2. In a measuring device of the character described, a substantially horizontal frame, a friction wheel mounted within the frame, a co-acting friction wheel ymounted within the frame, yielding means to move one friction wheel toward the other friction wheel, a register carried by the frame and operated by one friction wheel, uprights secured to the ends of the frame and provided at their lower ends with step ed brackets, and clamps adapted to be a justably secured to the steppedbrackets.

3. In a measuring device, a frame, fric-- tion wheels mounted within the frame, a register supported by the frame and operated by one friction wheel, an upright rigidly secured to one end of the frame and provided at its lower end with a stepped bracket, a clamp adapted to be adjustably secured to the stepped bracket, an extension secured to the opposite end of the frame and projecting longitudinally and outwardly from the frame, an upright provided at its upper end with a horizontal ange adapted to contact with said extension, a bolt adjustably connecting the flange and extension, a stepped bracket formed upon the lower end of the last named upright, and a clamp adapted to be adjustably secured to the last named stepped bracket.

In testimony whereof I aiiix my signature.

JACK H. BEvEL.
