摘要： A targeting putter having improved alignment and swing compensation means is disclosed. The putter comprises a putter shaft and a putter head having a striking face, heel and toe ends, and a reflective prism mounted thereon. The reflective prism, which is a right triangle prism, is located above the striking face of the putter head, and has a concave top or front face such that a wide-angle image of the green in front of the putter head is reflected to the eye of a golfer viewing the putter head from above. Reticles on the front and top faces of the reflective prism enable the golfer to sight through the prism, across the ball and to the pin, and to align the putter head perpendicularly to the intended path. A set of rotatably adjustable swingweights are located in counterbores in the rearward face of the putter head, allowing the center of mass of the putter head to be easily shifted in both the toe-to-heel and top-to-bottom directions. Such adjustments allow for compensation of deficiencies in the golfer's stroke that tend to twist the putter head, or put too much or too little force into the swing.
摘要翻译： 公开了具有改进的对准和摆动补偿装置的瞄准推杆。 推杆包括推杆轴和具有击打面，脚后跟和脚趾末端的推杆头以及安装在其上的反射棱镜。 作为直角三角棱镜的反射棱镜位于推杆头的击打面的上方，具有凹面的顶面或前面，使得推杆前面的绿色的广角图像被反射到 从上面观看推杆头的高尔夫球手的眼睛。 反射棱镜的前面和顶面上的网状物使得高尔夫球手能够穿过棱镜，穿过球和针头，并将推杆头垂直于预期路径对准。 一组可旋转可调节的摆锤位于推杆头的后表面的沉孔中，使得推杆头的质心能够容易地在脚趾和脚跟和顶部到底部的方向上移动。 这样的调整可以补偿高尔夫球手的中风中存在的倾向于扭曲推杆头部的缺点，或者对摆动施加太多或太小的力。

摘要： A rotating cutting blade and its drive motor are mounted on a wheeled support platform. The blade extends through a skid plate depending from the platform, in order to cut the concrete below the skid plate. The slot in the skid plate has its ends configured to fit within predetermined distances of the corresponding ends of cutting segments on the cutting blade. The cutting segments are configured to have a generally inverted "T" configuration in which a central cutting segment extends radially outward from two cutting segments located on opposite sides of the central segment. The exterior edges of the cutting segments may be square or rounded. The juncture between the central and shoulder segments may be square or rounded. The concrete is advantageously cut before it hardens to 1200 psi, without the use of an added lubricant, or above that hardness with lubricant if the cutting blade is supported within a sufficiently close distance by a skid plate.

摘要： A removal skid plate for use on a saw for cutting wet concrete. The portion of the skid plate in contact with the concrete has a slot therein through which a rotating cutting blade extends to cut a groove in the concrete. At a leading, cutting edge of the slot, a ceramic insert is placed in the skid plate to inhibit wear adjacent the cutting edge of the blade. The insert is removable and held by a resilient means which can vary the force exerted between the insert and the concrete surface being cut in order to minimize any undesirable markings which the insert might exert on the concrete surface.

摘要： In order to cut soft concrete before it has completely hardened, or about 12 to 18 hours after finishing, a rotating cutting blade and its drive motor are mounted on a wheeled support platform. The blade extends through a slot in the platform, and also through a skid plate depending from the platform, in order to cut the concrete below the skid plate. The slot and the skid plate are sized to support the concrete as it is being cut and to inhibit cracking and chipping of the concrete during cutting. The slot preferably has as little space as possible between the sides of the slot and the adjacent sides of the cutting blade. An extendable handle allows the device to be used beyond the physical reach of the operator.
