Abstract: A reciprocating rotary drill bit is disclosed to include a coupling member for coupling the drill bit to a source of drill bit drive power and a cutter member for drilling into a workpiece. The coupling member and the cutter member are slidably associated and include overlapping protruding portions which delimit the upward and downward travel of the cutter member with respect to the coupling member. The slidable association permits reciprocation of the cutter member with respect to the coupling member as the drill bit is rotated into the workpiece. The coupling member also includes protrusions which extend into grooves defined in the cutter member to rotationally secure the two members whereby the cutter member rotates when the coupling member rotates.
Abstract translation: 公开了一种往复式旋转钻头，其包括用于将钻头连接到钻头驱动力的源的联接构件和用于钻入工件的切割构件。 联接构件和切割构件可滑动地相关联并且包括重叠的突出部分，其限定切割构件相对于联接构件的向上和向下行进。 当钻头旋转到工件中时，可滑动关联允许刀具构件相对于联接构件的往复运动。 联接构件还包括延伸到限定在切割器构件中的凹槽中的突起，以可旋转地固定两个构件，由此当联接构件旋转时切割构件旋转。

Abstract: An improved rotary drill bit comprised of two or more elongated generally cylindrical drill members the lower ends of which form a cutting face. Each of the drill members includes a plurality of vertically spaced rows of diamond-shaped openings disposed, or formed, in the sides, or wall, thereof, the openings in adjacent rows being offset from each other and overlapping at their upper and lower ends whereby as the lower ends of the drill member wear away, cutting edges are continuously formed thereon by the diamond-shaped openings.
Abstract translation: 一种改进的旋转钻头，其由两个或更多细长的大体圆柱形钻具构成，其下端形成切割面。 每个钻头构件包括多个垂直间隔开的一排菱形开口，其设置或形成在其侧面或壁中，相邻排中的开口彼此偏移并在其上端和下端重叠，由此 当钻头构件的下端磨损时，切割刃由菱形开口连续地形成在其上。

Abstract: A charcoal concentrating implement for a charcoal grill which restrains the charcoal in an enclosure resting on the firebox of the grill under the cooking surface either by itself, or in combination with the sides of the firebox. The charcoal is concentrated in only a portion of the firebox supporting surface. A quicker, hotter fire for cooking is obtained with a reduction in the amount of charcoal and charcoal lighter fluid required.
Abstract translation: 用于木炭格栅的木炭浓缩工具，其将木炭限制在围绕烹饪表面的格栅火炉下的封闭物中，或者自身或与火炉的侧面组合。 木炭仅集中在火炉支撑表面的一部分。 获得更快，更热的烹饪火焰，同时减少所需的木炭和木炭更轻的液体的量。

Abstract: A drill bit including a support member and a plurality of concentrically positioned, hollow, cylindrical cutting members connected to the support member is disclosed. Each of the cutting members includes a beveled edge obliquely extending between the inner and outer surfaces thereof. The beveled edges are aligned so that a tapered cutting surface is defined.

Abstract: A furniture structure which converts into a bed comprised of a pair of rectangular frame members, one slidably supported on top of the other, so that the top frame member can be moved relative to the bottom frame member from a position whereby the frame members are coincident to an expanded position whereby the top frame member has one end thereof supported on an end of the bottom frame member. A rectangular cushion is attached to the top frame member and a second rectangular cushion is removably positioned on top of the first cushion. The second cushion is of a thickness equal to the thickness of the first cushion plus the thickness of the top frame member whereby when the frame members are moved to the expanded position and the second cushion is disposed on the bottom frame member, the top surfaces of the cushions are positioned at equal heights above the floor.
Abstract translation: 一种家具结构，其转换成由一对矩形框架构件组成的床，一个可滑动地支撑在另一个的顶部上，使得顶部框架构件能够相对于底部框架构件从框架构件重合的位置移动 到扩展位置，由此顶部框架构件的一端支撑在底部框架构件的端部上。 矩形垫子附接到顶部框架构件，并且第二矩形垫子可移除地定位在第一衬垫的顶部上。 第二衬垫的厚度等于第一衬垫的厚度加上顶部框架构件的厚度，由此当框架构件移动到膨胀位置并且第二衬垫设置在底部框架构件上时，顶部表面 垫子位于地板上方相同的高度处。

Abstract: An improved rotary drill bit comprised of two or more elongated generally cylindrical drill members, the lower ends of which form a cutting face. A plurality of vertically spaced rows of rotatable cutting members are positioned around and between the drill members and are journaled thereto whereby as the lowermost row of the rotatable cutting members and the lower ends of the drill members wear away, the next adjacent row of cutting members is exposed.
