| 41 | Method for determining usage rate of breaking hammer, breaking hammer, and measuring device | US13510648 | 2010-12-20 | US08704507B2 | 2014-04-22 | Mika Oksman; Ilkka Lehmusvirta |
| A method and measuring device for determining the usage rate of a breaking hammer, and to a rock breaking device. The measuring device comprises a sensor for measuring a physical phenomenon caused by the operation of the percussion device. The measuring results are processed, and they are used to determine the start and end times of the operation of the percussion device. By means of a timing device, it is possible to determine the duration of an impact cycle which is added to a time counter. The durations of impact cycles added cumulatively to the time counter indicate the total percussion time of the breaking hammer. Impact pauses between impact cycles are also monitored, and pauses shorter than a predefined time limit are taken into account as part of the usage rate. | ||||||

| 43 | OIL PULSE ROTARY TOOL | US13115659 | 2011-05-25 | US20120000684A1 | 2012-01-05 | Manabu SUGIMOTO |
| A sleeve body with bearings interposed between the sleeve body and a center shaft portion is integrally coupled to an oil pulse generator. A coupling body is rotatable together with the output portion. Balls are fitted between an outer surface of the sleeve body and an inner surface of the coupling body. Cam grooves are L-shaped in plan view, and formed in a portion of the outer surface of the sleeve body at which the balls are fitted. Rotation of the output portion is transmitted from the coupling body to the sleeve body and the oil pulse generator via the balls. When rotational speed between the sleeve body and the coupling body is different, the balls relatively turn in the cam grooves to move the coupling body forward against an urging force of the coil spring so as to relieve an impact. | ||||||
| 44 | TOOL FOR INSTALLATION OF TUBING IN FLOORING | US12435610 | 2009-05-05 | US20100281664A1 | 2010-11-11 | Dominic A. DiMambro; Raymond T. Kapala, Jr. |
| A tool for installing tubing in channels of floor panels comprises a handle attached to an upper portion of a front frame and a pair of wheels attached to a bottom portion of the front frame, a pneumatic drive, mounted between a front frame spacer and a bearing block, drives a hammer assembly for pushing the tubing into the channels, and a steering block is secured under the bearing block by a bearing assembly which enables the steering block to rotate about a bearing. An upper portion of a rear strut attaches to the bearing block and a pair of wheels attach to the lower portion of the rear strut. The tool quickly and efficiently installs the tubing into the flooring channels as the tool is rolled along the floor panels when an air source is attached to an air coupling on the pneumatic drive. | ||||||
| 45 | Electrical control system | US111767 | 1987-10-23 | US4802787A | 1989-02-07 | Marvin G. Bays |
| A control apparatus for a pavement breaker which includes a carriage, a lifting means for raising and lowering an impact arm which impact arm includes a tool for impacting a surface, mounted on one end and an oscillating member mounted on the other end. The control apparatus basically includes electrical apparatus for measuring the total weight being applied through the lifting means to the tool when it is in contact with the surface to be impacted and apparatus for limiting the amount of horizontal force that can be applied to the impact arm during the process of impacting the surface of the earth. A processor receives an electrical signal from the electrical apparatus which is applied to the lift control apparatus in a manner to stabilize the lifting force. A signal output is generated by the horizontal force limiting apparatus when a predetermined amount of horizontal force is received by the electrical device. The generated output signal is communicated to the lift control apparatus for removing the vertical force or weight from the tool to an extent necessary to remove the excessive horizontal force being applied to the impacting apparatus. | ||||||
| 46 | Pneumatic impact hammer | US718520 | 1985-04-01 | US4625812A | 1986-12-02 | James L. Pool |
| Pneumatic impact hammer for driving a frost plug into an engine block. The hammer includes a port for interconnection to a supply of compressed air, a chamber, a trigger, an elongate tube, a mallet slidably mounted within the tube, and a driver extending from one end of the tube. Compressed air is received by the chamber. Upon depressing the trigger, the compressed air within the chamber is substantially instantaneously applied to the back of the mallet. Consequently, the mallet is driven down the length of the tube toward the driver. The mallet impacts against the driver which, in turn, drives the frost plug into the engine. | ||||||
| 47 | Pneumatic impact device | US529908 | 1974-12-05 | US3990351A | 1976-11-09 | Bertil Waldemar Sundin |
| A pneumatic impact device comprising a housing, a drive piston and a piston rod. At the forward end of the piston rod there is attached a tool intended for metal working like punching, cropping or forging. The housing contains a drive chamber, an air charge chamber, a reverse chamber and a retard chamber. The piston rod is provided with two forward-facing, annular shoulders one of which constitutes a reverse piston for working in the reverse chamber and the other a retard piston for working in the retard chamber. For being protected from impact strains, the drive piston is longitudinally displaceable relative to the piston rod. During the working strokes, the drive piston cooperates with a backwardly facing shoulder on the piston rod, but just before the latter reaches the point where the tool hits the billet to be worked, the drive piston is stopped in the drive chamber and is thereby separated from the piston rod shoulder. | ||||||
| 48 | Impact tool | US3565183D | 1968-12-13 | US3565183A | 1971-02-23 | JAYNE MURRAY L |
| An impact tool for loosening and breaking homogeneous material such as compacted or frozen earth, black top and concrete. The tool is adapted to be mounted on the boom of a backhoe or the like, and it is powered by the hydraulic system of the apparatus on which it is mounted or by a separate system. A tool element, such as a hardened point, in integral with or mounted on an anvil arranged for limited longitudinal movement in a housing. A hammer coacting with the anvil is energized by a spring, preferably a pneumatic spring. A hydraulic cylinder moves the hammer against the spring, and when the spring is compressed in desired amount, the piston rod of the cylinder is cammed away from the hammer, thereby permitting the spring to drive the hammer with great force against the anvil. The tool is arranged so that operation thereof occurs only when the tool element or point is positioned against the work and the movable anvil has an inward relation with its housing, thereby providing a ''''dead man'''' control feature. In basic form the tool has a single hammer and a single cylinder. Modifications of the basic tool contemplate a double cylinder, single hammer device which increases the frequency of operation by a factor of two, and a double cylinder, double hammer device which in effect is the combination of two single hammer, single cylinder devices in a single tool.
