3,031,75 SAFETY RAZR WlTH HDJGED BLADE COVER Joseph Epifania, B0. Box 18, Paulsboro, NJ. Filed Apr. 24, 1959, Ser. No. 808,637 1 Claim. (Cl. Sti- 58) This invention relates to a safety razor construction.

It is the principal object of the present invention to provide a safety razor construction in which the cover plate for a double edge blade is a single one and swung upon one side of the razor which makes for a single closing action for a double safety razor.

It is another object of the invention to provide a safety razor construction comprising a single plate for covering a double edge blade which is adjustable by the central longitudinal extending guide bar over which the blade is placed without interfering with the operation of the guide bar the cover plate being pivotally connected to arms extending laterally from the opposite ends of the guide bar, and means on the pivotal cover plate engageable with the flxed plate to cam the same to the open position and to limit the outward pivotal movement of the cover plate.

Other objects of the invention are to provide a razor construction having the above objects in mind, which is of simple construction, has a minimum number of parts, inexpensive to manufacture, easy to operate, compact, sanitary, permits easy cleaning of the razor, easy removal of the blade, eiective and eliicient in use.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing in which FIGURE l is a perspective View of a razor construction according to one form of the invention with the cover part closed upon the blade supporting fixed part, and the cover being slotted to permi-t the blade guide member to be extended therethrough,

FIG. 2 is a perspective view of the razor shown in FiG. l with the cover plate in its open position and the blade guide extended,

FIG. 3 is an enlarged vertical sectional View taken on line 3-3 of FIG. 2,

FIG. 4 is an enlarged fragmentary vertical elevational i view of the razor construction with the cover in its open position,

FIG. 5 is a similar elevational view with the cover in its closed position.

Referring now to the figures, represents a hollow handle having a turn knob 11 journalled on its outer end. This turn knob is internally threaded as indicated at 12 for connection with threaded lower` end 13 of a rod 14 having a laterally-extending guide portion 15 for entering the `slot of the razor blade 16 for the purposes of positioning the blade upon a ixed blade supporting body 17 xed to the inner end of the handle 10. The laterally-extending guide portion has

end extensions

18 and 19 from which there extends respectively and transversely of the ends of the razor head respective arms Ztl and 21. Between the outer ends of these

arms

20 and 21 there is pivotally connected a top cover plate 22 by pivot connections indicated at 23 and 24. The cover plate 22 has inwardly extending and laterally spaced

support elements

25 and 26 by the ends of which the cover plate is pivotally' connected to the

arms

20 and 21 carried by the adjustable blade guide portions 15.

The blade supporting body 17 has the usual depending transversely extending portions 27 and 2S over which the edges of the cover

plate support elements

25 and 26 are extended, fulcrumed and limited in their movement to cause the cover plate to be lifted and lowered with the movement of the laterally extending blade guide portion. These

support elements

25 and 26 have lugs 29 which engage with the underside of depending blade guide portion as at 27 to stabilize the inward movement of the cover plate 22 when it has become aligned with the portion 15 and its elongated slot 31 receiving the portion l5. Depending from the sides of the body 17 at each end thereof are depending

lugs

32 and 33 between which the

extensions

18 and 19 pass. Each

lug

32, 33, is spaced from the

respective arm

25, 26 to form a slot through which the adjacent extension 1S or 19 passes, the slots not being provided with a reference numeral for the reason that they do not show in any of the views. The depending lug 33 is longer than the depending lug 32 and extensions of the arms 2t) and 21 thereover serve to guide the downward movement of the cover plate and to hold it aligned so that its slot 31 will receive the guide portion 15. As the cover 22 is moved from its closed position overlying the body 17 to its open position away `from the body 17, control of the same is kept by the lug 2g on the

cover support elements

25 and 26 engaging with the sides of the guides 32 in the manner as best shown in FIG. 4.

Accordingly as the knob 11 is turned, the guide portion 15 is held raised or lowered, by the threading of the portion 13 of rod 14 in the turn knob 11. Since lthe portion 15 has rigidly connected thereto the transversely-extending

arms

20 and 21, the cover plate will be pivoted between open and closed positions since it is fulcrurned upon the depending portion 27 of the blade supporting body 17. The lugs Z9 limit the swinging movement of the cover plate since they engage between the inner ledge 27 of the depending portion 27, FIGS. 4 and 5 and the vertical edges of a depending guide portion 32 on the fixed blade supporting body 17.

While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

What is claimed is:

In a safety razor construction, including a hollow handle, a turn knob journaled on one end of said handle, a rod extending through said handle, and adjusted by said turn knob, said rod having a laterally extending blade guide portion on one end, and a blade supporting body iixedly secured to the other end of said handle and said guide portion being adjustable therethrough, a lug projecting perpendicularly from each end of said body, a transversely extending arm projecting from each end of said blade guide portion and movable therewith, each of said arms being spaced from the adjacent body lug to form a slot, a one piece cover conformably shaped to extend over said blade supporting body disposed in overlying lrelation with respect to said blade supporting body, said cover having a slot extending `through its midportion for substantially the Width of said cover and slidably receiving said blade guide portion of said rod, a support element projecting from each end of said cover and on the same side thereof, and a pivot connection connecting one of the adjacent ends of said support elements to the adjacent arm for movement of said cover from `the overlying position to a position away from said blade supporting body.
