Abstract: A wood cutting machine having a first saw blade adapted to cut a horizontal groove in a wood member, a second saw blade adapted to cut a vertical groove in the wood member, motive means for moving the saw blades selectively into engagement with the wood member, and clamp means automatically operable before operation of the motive means for holding the wood member in place during a cutting operation.

Abstract: A razor blade assembly is provided having a molded plastic body member with a guard member mounted thereon. The body member comprises wall structure defining a pair of slots for receiving a blade means, and forming a support means on which the blade means rests. The blade means comprises a pair of cantilever spring portions formed in the blade means got contacting the support means when the blade means is disposed for slidable movement in the slots whereby the blade means is resiliently mounted in the body member.

Abstract: A safety razor incorporating blade magazines and magazines therefore, the blades being incorporated in individual units, each comprising at least one blade, carried by a support plate. A plurality of units are housed as a stack within a magazine, open at one end and providing a guard and a cap. The units are stacked in the magazine extending transversely thereof, the outermost unit being positioned at the mouth of the magazine with its blade positioned between the guard and the cap and its support plate and the magazine wall providing seal against the ingress of debris and moisture. Means are incorporated in the magazine or razor handle to eject the outermost unit from the magazine and replace it with the next unit in the stack.

Abstract: A safety razor head comprising a guard surface and a cap surface is provided with a plurality of parallel riblets disposed on the head for contact with the surface being shaved, during use of the razor. The riblets may be disposed on the cap surface or on a substantially thin film material extending from the guard surface to the cap surface and are effective to improve shaving comfort.

Abstract: A safety razor assembly is provided comprising a plurality of stacked discrete shaving elements. Each of the shaving elements contains a shaving head mounted in an upwardly facing enclosure, and wall structure forming a downwardly facing cavity for receiving the shaving head enclosure of another shaving element in interfitting engagement therewith. The assembly comprises a sufficient quantity of elements that, when stacked one upon the other, form a gripping handle which is employed when using the topmost shaving head in the shaving process. An overcap is provided having an upwardly projecting protuberance with side wall dimensions equal to those of each shaving head enclosure and a downwardly facing cavity having interal dimensions equal to those of each shaving head cavity.

Abstract: The present disclosure is directed to the combination of a primary box having closed side and end walls, a bottom and a hinged top with a pair of chamfered U-shaped inserts having the bases of the U-shape in unattached abutting relationship with the outside legs of the U-shape glued to the inside walls of the box with a cutting line marked on the outside of the box adjacent to the unattached abutting bases of the U-shaped inserts for cutting the box into two separately transportable secondary boxes of product containers and for selling and transporting less than all the containers of the primary box.

Abstract: A safety razor comprises a pivotal cap member which in a first position is effective to obscure the cutting edge of the blade or blade members to protect the cutting edge from contact with other objects. The cap member when pivoted to a second position exposes the blade cutting edge and positions a skin engaging guard surface adjacent the blade cutting edge to provide a desired shaving geometry.

Abstract: A plurality of individual thin-walled generally disk-shaped blades are resiliently mounted in an elastomeric pad. The elastomeric pad, with its individually mounted blades, is disposed over a flexible sponge-like member. The shaving device is flexible and maintains maximum skin contact regardless of the contour of the area being shaved by providing that each individual blade is independently movable with respect to the other blades.

Abstract: In a twin head dry shaver, the shaver heads are carried at the upper end of a four-bar mounting linkage comprising vertical side members 1A, 1B and bell crank links 2, 3 pivotally connected to the side members at points 7, 8 and 9, 11. The links are pivotally connected to the frame by pivot pins 4 and 6 set above and mid-way between the connections to the side members, thus rendering the heads highly sensitive to cut of balance forces acting on the heads so that they may move vertically, relative to each other to restore the balance.

Abstract: A razor including a handle and a blade unit mounted on the handle for pivotal movement thereon, the blade unit comprising a housing having a blade therein, a pair of projections extending from an underside of the housing toward the handle, and a leaf spring extending from the handle toward the blade unit, the leaf spring being fixed at a first end to the handle, a second end of the leaf spring being disposed between the projections and in contact therewith, the spring being twisted about its lengthwise axis and retained in a twisted condition by the projections, the leaf spring thereby exercising a force on each of the projections to cause the blade unit to be biased toward a neutral position on the handle.

Abstract: A safety razor assembly is provided having a removable cap slideably received in interfitting engagement with the razor head. The cap is provided with a shaving aid member having a skin contacting surface disposed adjacent, and extending along the forward edge thereof, and a cover wall. In the shaving mode, the cap is positioned on the shaving head with the cover wall below the head and the skin contacting surface disposed adjacent the blade edges in a preferred shaving geometry. The cap may be removed and positioned on the shaving head in the inverted position, with the cover wall disposed over the blade edges for protection of the blades, or adjacent items, during non-use of the safety razor.

Abstract: The present disclosure is directed to a shaving cartridge for use with a razor handle having a pair of cartridge engaging shell rocker bearings biased toward one another each of which has at least one undercut rocker bearing for receiving the cartridge. The cartridge has at least one blade thereon and has curved under surfaces pivotal upon and relative to the rocker bearing surfaces of the cartridge engaging shell rocker bearings. At least one protrusion extends from the curved under surfaces of the cartridge and is positioned to engage the shell rocker bearing surfaces on the cartridge when the cartridge is introduced to the shell bearings of the handle to bar reverse insertion of the cartridge in the handle so that the shaving blade of the cartridge when rockably engaged within the grip of the shell bearings is in a shaving ready position every time avoiding accidental reversal of the cartridge and its cutting blades when positioned on the handle for shaving.

Abstract: A set of coloring crayons comprising a number of blocks of crayon each of polygonal form with a central hole to receive a spindle on which the blocks are securely stored with the aid of releasable retaining means, such as nuts.

Abstract: The present disclosure is directed to a plurality of individual protective safety razor head unit open top casings and a tray for storing the plurality of casings in side-by-side relationships. Each of the casings are adapted to retain a single safety razor cartridge unit therein, each of which have at least one blade and a head cartridge member to which the blade is permanently secured and which also provides a guard surface. The head unit is detachably engageable with a safety razor handle. Each casing defines a single chamber in which a single shaving head unit is retained. The structure in each casing retains the head unit therein against accidental removal in such a manner that the cutting edge of the blade is protected against damage and wherein the head unit is engageable by the handle while the head unit is still within the casing. Each head unit when engaged with the handle is withdrawable from its casing by means of rocking the handle.

Abstract: A method of manufacturing a razor blade is disclosed wherein a polymer material is coated onto the blade edge. The polymer material is applied to the blade edge in a coating solution after which the blade is passed through a rapidly changing magnetic field in close proximity to the blade, which induces a current to generate heat for sintering the material to the blade edge.
