Abstract: A quilting frame including inner and outer co-planar closely, uniformly, adjustably fitting rectangular wooden frames, the inner frame being of a rigidly integrally unyielding character, the co-planar adjustability between the inner and outer frames being provided by mitering and rigidly uniting side and end pieces of said outer frame at both ends of one of the diagonals of said outer frame, and mitering and spreadably adjustably uniting the other ends of said side and end pieces of said outer frame located at the opposite ends of the other diagonal of said outer frame, thereby facilitating the joint use of two hands to simultaneously uniformly adjust the radial peripheral spacing of the two rectangular frames, as well as the telescopic spaced correlation of said frames.

Abstract: A belt drive clutch having a hexagonal sleeve splined on a power output shaft and carrying an outer sheave disc. A drive belt supporting annulus is freely rotatable on the sleeve and located between the outer sheave disc and an inner sheave disc. The inner sheave disc has a stud shaft extending inwardly and having a hexagonal bore matching the hexagonal external conformation on the sleeve. Ball bearings are assembled on the stud shaft and a clutch control ring is assembled on a peripheral race of the ball bearing. A camming arrangement shifts the clutch control ring axially to engage or disengage the belt by optionally constricting or expanding the space between the outer and inner sheave discs.

Abstract: The subject trailer includes a single tubular for-and-aft horizontal tow-bar towed at its front end by a tow ball hitch. Welded vertically to a rear end portion of the tublar tow bar is a tubular mast having pulleys guiding a cable from a winch on said tow bar up and over said mast and connecting to a towing hammock for attaching to a vehicle to be towed. The hammock has a central pair of flanges guiding the hammock vertically on the tubular mast while allowing the mast to rotate 30.degree. on its own axis between the flanges while bolted to the hammock after the latter being hoisted to the vehicle towing level. Welded to the tow bar is a rigidly symmetrically laterally extending tubular axle co-axially rotatably mounting a pair of #15 sized balloon tired wheels on the opposite axle ends, causing the trailer to track straight behind the towing vehicle by flexing, both at the vertical tow-ball socket joint and at the vertical 30.degree. mast-hammock-flange-and-bolt-joint.

Abstract: A rotary cutter head mounted on the end of a handle to power rotate at high speed one or more centrifugally whirled free ends of a reserve of nylon line wound on a spool co-axially pivotally mounted within the head.A co-axially spring biased indexer is subject to inertia applied through the handle while the device is running to effect the feedfing of precise increments of line from the spool to the free line ends. The indexer is automatically self-inhibiting when the line ends reach a predetermined optimum length of approximately eight inches and continues to be self-inhibiting until the line ends wear down, in use, to less than a predetermined minimum length of approximately five inches.

Abstract: A pump barrel open at its lower end is coupled at its upper end by a tubular adapter assembly to the lower end of a pump tubing string, this assembly presenting an internal bevelled sealing-latching annulus, an axially bored pump head being radially expansively spring latched in a fixed axial sealed relation with the annulus to seal the upper end of the pump barrel from the adapter assembly to form a pump compression chamber surrounding a hollow polish rod extending upwardly from a plunger mounted on the lower end of the polish rod for reciprocation in the pump barrel, the plunger carrying tandem travelling valves close beneath its connection with the polish rod, the lower valve opening to receive oil through the barrel and plunger on the down stroke and concurrently delivering such oil into the compression chamber, the upper valve closing on the down stroke and opening on the up stroke during which the lower valve closes to expel oil trapped in the compression chamber upward through the upper valve into the

Abstract: A hydraulic jar apparatus to be disposed in a drilling string embodying inner and outer telescopically arranged elements. Overlapping portions of the elements provide an annual chamber confining an operating liquid by an annular seal fixed to the outer element at the lower end of the chamber and an annular Polly Pack seal fixed to the outer element at the upper end of the chamber. A piston is extended radially from the inner element into the chamber and the chamber is divided by a cylinder on the outer element into low and high pressure sections. Impact shoulders are provided on the elements in axially opposed relation to produce a jarring blow and the elements are telescopically coupled by a hexagonal spline sub assembly.

Abstract: A rotary cutter head mounted on the end of a handle to power rotate at high speed one or more centrifugally whirled free ends of a reserve of nylon line wound on a spool co-axially pivotally mounted within the head.A co-axially spring biased indexer is subject to inertia applied through the handle while the device is running to effect the feeding of precise increments of line from the spool to the free line ends. The indexer is automatically self-inhibiting when the line ends reach a predetermined optimum length of approximately eight inches and continues to be self-inhibiting until the line ends wear down, in use, to less than a predetermined minimum length of approximately five inches.

Abstract: A line supply spool rotatably confined co-axially within a thin housing shell having a splined mounting on a polygonal arbor through which said housing shell is supported at the lower end of a manually held engine powered handle while the shell is being spun at a high speed on a vertical axis. Free line ends are progressively fed peripherally from the spool through equally spaced windows provided in the housing shell by controlled rotation of the spool relative to the housing shell, the control of the rotation of the spool being optionally effected manually while the tool is shut down or automatically while the tool is spinning, the election being made by a minor selective shifting of a few parts, this election being readily reversed, whenever desired.

Abstract: A line supply spool rotatably confined co-axially within a thin housing shell having a splined mounting on a polygonal arbor through which said housing shell is supported at the lower end of a manually supported engine powered handle while the shell is being spun at a high speed on a vertical axis, free line ends being progressively fed peripherally from the spool through equally spaced windows provided in the housing shell by controlled rotation of the spool relative to the housing shell.The housing shell comprises two like die cast halves which abut each other in a medial radial plane with which the line feeding windows are symmetrically related. Each window is formed by two matching notches including four cups enclosing opposite ends of two tubular closely parallel line guiding rollers. Cast integrally with the four cups are four co-axial stub shafts on which the hollow rollers are centered internally.

Abstract: An improvement on the tool shown in U.S. Pat. No. 3,853,187, this tool also embodies in a single structure inner and outer telescopically related tubular elements confining a body of operating liquid and comprising a hydraulically retarded up-blow jar, actuated by placing a lifting strain on the drill string, and a simple mechanically retarded down-blow jar actuated optionally by a controlled downward pressure of the drill string on the jar. This jar differs from the patented jar by inverting said structure and actuating said two jar mechanisms respectively by upward and downward movements of said inner element. It also embraces improved specific control devices for said up-blow and down-blow jar mechanisms.
