| 144 | Folding saw frame | US11111537 | 2005-04-21 | US20060016311A1 | 2006-01-26 | Kerry Seymour |
| A saw frame that may be folded and locked in a more compact position. One saw frame disclosed comprises a first section of the frame that is pivotably attached to a second section of the frame so that the first section can pivot upward and fold back down onto the second section, resulting in a considerably more compact structure when folded. The pivot point is located so that, when folded, the frame can be lifted from a handle or lifting point at the frame's folded center of gravity without substantially tilting. Locking pins secure the frame in its folded or open configurations, so that the frame is not permitted to pivot when not desired. | ||||||

A pair of positioning rods each has an elliptic eccentrically integrated at lower end engaged into the positioning plate for rotatably operated the expanding plates to lock or unlock the positioning plates to achieve a non-step gripping a cutting lumber on the rectangular board. | ||||||
| 147 | Handle including two handgrips and/or a hand alignment mechanism | US10444136 | 2003-05-23 | US20040231172A1 | 2004-11-25 | Eduardo J. Jimenez |
| A handle having improved ergonomics and relatively compact low cost design is provided. In particular, the handle may include two hand grip areas which may be integral with one another. The two hand grips may be approximately perpendicular to one another. Further, one or both of the grip areas may include grip alignment mechanisms that improve the ergonomic alignment of a persons hand on the hand grip area of the handle. In another aspect the hand grip(s) may have smooth rounded grasping surfaces to provide comfort when grasped by a hand. The alignment mechanism(s) may be placed at an optimal location on the hand grip(s) area and result in improved control and comfort during use. In addition, one of the alignment mechanisms may serve a dual purpose of hand alignment and as a stop that prevents a person's hand from slipping off of the grip area during use. | ||||||
| 148 | Device for cutting pieces of wood to size | US10824918 | 2004-04-15 | US20040206221A1 | 2004-10-21 | Franz Loffler |
| A device for cutting pieces of wood to size, in particular meter-long logs, to form log pieces or firewood, has a frame for accommodating meter-long items. The frame comprises spaced-apart holding elements that are designed in a U shape and between which free regions for saw cuts are provided. It is possible for the frame to be shifted from a sawing position about a pivot axis into an unloading position. | ||||||
| 149 | Folding sawhorse with locking shelf | US09634245 | 2000-08-08 | US06488119B1 | 2002-12-03 | Rick DuRapau; Joe Dvoracek |
| A folding sawhorse of the type comprising two trestle like frames that are hingedly connected at their tops. The shelf is hingedly attached to a lower strut of one frame and slidably attached to the legs of the opposite frame. The slidable attachment is by means of pairs of pins that are secured to one end of the pivoting shelf and are also yoked to longitudinal ridges that are in the legs of the opposite frame. To open the sawhorse from its closed, storage position, the frames are spread apart slightly, thereby allowing gravity to pull the shelf downwardly and concurrently causing the frames to spread outwardly to their open, working position. The sawhorse will stay in this locked open position without any additional latching mechanisms until the close procedure is initiated. To close the sawhorse for storage, a light upward pressure is applied on the edge of the pivoting shelf, causing it to move upwardly and concurrently causing the frames to pivot inwardly toward each other to their closed storage position. | ||||||
| 150 | Collapsible sawhorse trestle and leg strut | US821902 | 1997-03-21 | US6021866A | 2000-02-08 | Millard Meeks |
| Disclosed herein is a trestle-type, dual-frame sawhorse including first and second generally rectangular, identical frame members, hinged together along their horizontal top beams, each having depending legs with horizontal leg braces parallel to the top beams. Each leg has a longitudinal slot with a transverse pin which passes through a bound space defined within a rigid, rectangular-framed strut. Each strut has a pair of longer side members and a pair of shorter side members, and is bound by the pins into the slots of both legs of a leg pair. The strut can be moved to a vertical position whereby the legs of the sawhorse are held together, or the strut can be allowed to drop into a horizontal position where it keeps the legs from splaying farther when the sawhorse is under load. Detent notches in the inner surfaces of the strut permit the sawhorse to resist being collapsed back into its folded orientation. An alternative embodiment of the sawhorse includes an additional, generally vertically-oriented structural member integral to each frame member of the sawhorse, having an upper end fixed to the underside of the horizontal top beam and a lower end fixed to the horizontal leg brace. Each vertically-oriented structural member includes a slot with a transverse pin. Thus, a pair may have a single strut bound between them to permit the frames with which they are associated to be fixed securely in either an open or closed orientation. | ||||||

In one aspect, a serrated helical wheel provides adjustment to contact the saw blade to the strainer plug body of the bathtub drain. In another aspect, an adjustable cutter wheel includes a serrated helical wheel for providing adjustment to contact the cutter wheel to the strainer plug body of the bathtub drain. | ||||||
| 152 | Hand power table saw | US749111 | 1976-12-09 | US4096777A | 1978-06-27 | Charles Lee Adams |
| There is disclosed woodworking apparatus which is handpowered but permits accurate cuts by unskilled persons comparable to those which might be made by a radial arm or table saw. The apparatus includes a guide in which a handsaw is retained and restrained for cutting motion along the straight line, a supporting surface to support a workpiece in relation to the handsaw, and guides which co-operate with rulers to permit presetting of the apparatus for a desired cut, together with clamping devices which hold the workpiece to the table securely against the motion of the handsaw, at the same time avoiding interference of the clamps with the handsaw as it passes through the workpiece. The guide for the handsaw is formed of very rigid structural material such as steel angle iron which is faced with a plastic material of moderate hardness that resists abrasion or cutting by the handsaw to a considerable degree but is not so hard as to rapidly dull or distort the teeth of the handsaw. | ||||||
